 ### The root documents split into `docs/` pages (#190)
 The task and explanation parts of `README.md`, `INSTALL.md`, `INSTALL-MCP.md` and `EVALS.md` are now single English pages: eleven how-to guides under `docs/how-to/` (ingest, capture, guideline export, query, maintenance, weekly review, Obsidian, updating an instance, troubleshooting, the MCP read server, tracing and scoring sessions), a hand-written `docs/reference/configuration.md`, and `docs/explanation/architecture.md` and `telemetry-and-evaluation.md`. A guide says what to prepare, what to tell the agent and where it stops; it links an agent's procedure instead of retelling it. `INSTALL-MCP.md` and `EVALS.md` are gone from the root and from `dist export`, so an upgrade removes them as retired; `README.md` is a landing page, and `INSTALL.md` keeps only the installation itself. Pointers in messages and command records, among them `version check`'s, name the new pages.

 # EVALS.md - Telemetry and Evaluation
 How this repository observes what an agent did, and how that record turns into a score.
 **This file is for humans.** It explains the design and points at the code. The rules an
 agent must follow live in [tools/CONTRACT.md](tools/CONTRACT.md) and
 [reports/CONTRACT.md](reports/CONTRACT.md); repeating them here would create the second copy
 that [AGENTS.md](AGENTS.md) exists to prevent.
 ## Why, beyond the unit tests
 The pytest suite under `tools/chemenu/tests/` - in the origin repository; `dist export` does
 not ship it - checks the **compiler**: given this input, does `wikitool` produce that output. It says nothing about the two things that actually go
 wrong in practice - whether the *agent* followed the contracts, and whether the pages it wrote
 are any good.
 Those need a different kind of check, and the vendored knowledge base has the theory:
 - [oracle-strength-spectrum](commonplace/kb/notes/oracle-strength-spectrum.md) - correctness
  checks form a gradient from hard (deterministic) to none (vibes). The engineering move is to
  *harden* oracles progressively, not to reach straight for a judge.
 - [evaluation-automation-is-phase-gated-by-comprehension](commonplace/kb/notes/evaluation-automation-is-phase-gated-by-comprehension.md)
  - comprehension, then specification, then generalization. A judge built before anyone has
  read real failures optimizes a proxy.
 That ordering is why this file describes a lot of telemetry and only a little scoring: reading
 real traces is the first phase, and it cannot be skipped.
 ## Architecture
 Three sources, three different jobs.

 ```
 - **The repo layer is the truth.** `wikitool` records its own calls, so what happened *to the
  wiki* is known even when no hook fired and no runner was involved.
 - **The runner owns session boundaries.** Not every harness reports a session start - Mistral
  Vibe has no such hook - so the process that launches the agent is what brackets a run.
 - **Hooks enrich.** They add the tool calls the repo layer cannot see: file reads, greps,
  shell commands, prompts.
 Everything joins on one session id, resolved the same way by every source that has to pick
 one - see `chemenu.session`. The chain is `WIKITOOL_SESSION_ID`, then a harness's own session
 variable where one is registered (`chemenu.session.HARNESS_ENV_VARS` - Claude Code's
 `CLAUDE_CODE_SESSION_ID` today), then the parent process id. The middle step exists because
 the last one does not survive a harness that runs every tool call in its own freshly
 initialised shell: `os.getppid()` is then a new "session" per call, and neither the join nor
 the Iteration Budget Gate below can see more than one or two calls of a real run. A harness
 only earns an entry in that chain once a live session has been observed setting the variable,
 confirmed to be the exact id its own hooks write elsewhere in a trace - a name that merely
 looks plausible would mis-key a session more quietly than the pid fallback it replaced.
 A trace hook that only *observes* tool calls (a `PreToolUse`/`PostToolUse`-style wiring) does
 not by itself fix a harness whose events carry a different id than `wikitool`'s own emitter -
 the two still would not join. Wiring such a hook is only worth doing once this fallback chain
 already keys both sides on the same id.
 ## The trace
 One JSON object per line, appended to `reports/telemetry/<session>/trace.jsonl`. The contract
 is [tools/chemenu/telemetry/schema.py](tools/chemenu/telemetry/schema.py).
 | Field | Meaning |
 |---|---|
 | `v` | Schema version |
 | `ts` | ISO-8601 UTC, microsecond precision |
 | `session_id` | The join key - `chemenu.session`'s fallback chain: `WIKITOOL_SESSION_ID`, else a registered harness variable, else the parent process id |
 | `pid`, `seq` | `seq` counts **within one process**. Sort a trace by `(ts, pid, seq)` |
 | `source` | `wikitool`, `runner`, or a harness name |
 | `event` | See below |
 | `attrs` | Normalised payload - same field names whichever harness produced it |
 | `run_key` | The `work/<runkey>/` run, when one is open |
 | `trace_id`, `span_id` | From `TRACEPARENT`, when the harness exports it |
 | `redactions` | Which secret patterns fired on this event |
 **Events.** The core - `tool.pre`, `tool.post`, `wikitool.call`, `gate.refused` - is available
 on every surface. Everything else (`session.start`, `session.end`, `session.error`,
 `prompt.submitted`, `assistant.message`, `turn.end`, `tool.error`, `instructions.loaded`,
 `subagent.start`, `subagent.stop`, `compaction`, `page.written`, `publish.commit`,
 `budget.state`, `gate.cleared`) is optional.
 **The degradation rule.** No scorer may *require* an optional event. Claude Code has thirty
 hooks and Mistral Vibe has three, so a scorer built on the rich end would silently report zero
 on the poor end - which reads as "the agent did nothing" rather than "this harness cannot
 say". Every `session.start` carries a `completeness` list naming the classes its harness can
 emit, so a scorer can answer "not measurable here" instead.
 **Budget and trace are not the same set.** The Iteration Budget Gate exempts read-only
 retrieval; the trace records it. What an agent looked at before acting is exactly what a
 trajectory scorer needs, and charging for a `search` would discourage the one habit that
 lowers cost.

 ### Claude Code
 `.claude/settings.json` wires `UserPromptSubmit` to `tools/trace_ingest.py`, through
 `tools/trace-hook` like every hook here (see the load-bearing details under Copilot CLI). That is what makes
 `clearance-ended-the-turn` scorable here: without a `prompt.submitted` event there is no turn
 boundary to place an exit-42 call and its `--confirm` on either side of, and the rule reports
 "cannot say" instead of a verdict.
 **No `PreToolUse` decision hook is wired**, and this is a finding, not an oversight. Verified
 against the live CLI on 2026-08-27 (this repo runs inside Claude Code): a `PreToolUse` hook
 returning `hookSpecificOutput.permissionDecision: "ask"` does **not** override a matching
 `permissions.allow` rule - permissions are evaluated before a hook's decision, so a hook cannot
 force a confirmation prompt on an already-allowlisted command. A `permissions.ask` rule *does*
 win, which is why `.claude/settings.json` carries one on the `--confirm` form of `publish`
 (`Bash(tools/wikitool publish --confirm:*)`): the clearing call prompts, ordinary publishes
 below the threshold do not. It is a prefix match, so it depends on `--confirm` sitting first -
 which is why `git_publish.rerun_command` always emits it there. Treat it as a useful second
 line, not a guarantee: an agent that reorders the flags routes around it.
 ### Copilot CLI
 [.github/hooks/wiki-trace.json](.github/hooks/wiki-trace.json) is committed, so a clone brings
 its own telemetry. Eleven events route to `tools/trace_ingest.py`; `disableAllHooks` in
 `.github/copilot/settings.json` turns them off without deleting anything. `userPromptSubmitted`
 is already among them, so `clearance-ended-the-turn` is scorable on Copilot CLI with no change
 needed.
 A `preToolUse` entry that forces a decision document on the clearing call would need Copilot's
 own decision-document schema verified against a live CLI first (this repo has none installed) -
 unverified, per the same rule that governed the Vibe adapter: an adapter that cannot be verified
 is not written.
 Four details in that file are load-bearing, and the first two hold for all three hook
 configurations:
 - **The interpreter is the venv's, never the script's shebang.** Each `bash` command is
  `./tools/trace-hook ...`, which runs `trace_ingest.py` with `tools/.venv`'s Python in either
  venv layout; each `powershell` command names `tools\.venv\Scripts\python.exe` directly. A
  hook command is a fixed string and cannot read `.wikitool-tools.json`, but the venv is
  created from the recorded interpreter at a fixed place, so it stands in for it. The shebang
  (`python3`) was the Microsoft Store alias in Git Bash on Windows, which made every hook there
  a silent no-op. Before the preflight has created the venv, `trace-hook` records nothing and
  exits 0.
 - **`./tools/trace-hook` has a PowerShell twin, `tools/trace-hook.ps1`.** PowerShell on
  Windows resolves the string to the `.ps1` first; without one, it hands the sh script to a
  file association and Windows asks which app should open it - on every hook event. A `bash`
  field alone does not keep the string out of PowerShell: Copilot CLI also reads
  `.claude/settings.json` and runs its single `command` under PowerShell on Windows. The twin
  keeps the sh script's rules - venv Python, silent without a venv, exit 0 whatever happens -
  and avoids `#Requires -Version 7`, because VS Code starts hooks under Windows PowerShell 5.1.
  Each `powershell` command here is written so 5.1 can parse it, too.
 - **Every command ends in `|| true`.** `preToolUse` hooks are *fail-closed*: a non-zero exit
  denies the tool call. Without the guard, a missing interpreter would turn the observer into
  a blocker that refuses every tool call in the session. (Timeouts are fail-open, so the
  5-second `timeoutSec` is not a hazard.)
 - **The event name is passed explicitly.** Copilot serves two payload dialects - camelCase
  event names give camelCase fields, PascalCase names give the VS Code/Claude snake_case
  shape. `--event` means the mapping does not depend on which one a config chose.
 ### VS Code Chat
 No hooks, so nothing observes a session while it runs. The chronicle store
 (`session-store.db`, same schema as Copilot CLI's) keeps sessions, turns and touched files,
 and [tools/import_chronicle.py](tools/import_chronicle.py) reconstructs a trace from it after
 the fact:
 ```bash
 tools/import_chronicle.py --dry-run     # this repo's sessions
 tools/import_chronicle.py --session 0f1e2d3c
 ```
 The store starts empty; `/chronicle reindex` fills it - and also syncs session data to your
 GitHub account, so run it deliberately rather than from a script. A reconstructed trace marks
 itself `reconstructed: true` and its `completeness` names `tool.post` but not `tool.pre`: the
 store records that a file was touched, not that a tool was about to run.
 ### Mistral Vibe
 [.vibe/hooks.toml](.vibe/hooks.toml) declares the three hooks Vibe has, and
 [.vibe/config.toml](.vibe/config.toml) carries the telemetry policy in the repository rather
 than in someone's shell profile. Both were validated against the installed CLI's own loader
 (`mistral-vibe 2.24.2`) rather than against the documentation.
 What that verification turned up, and what it changes:
 - **A failing hook cannot block anything.** Vibe's failure semantics are the mirror image of
  Copilot's: with `strict = false` - the default - a crash or a timeout is a no-op warning.
  Only a hook that opts into `strict` can deny a tool call.
 - **`post_agent` carries no response text.** Its payload is the session context and nothing
  else, which is why it maps to `turn.end` rather than to `assistant.message`.
 - **`enable_telemetry` defaults to `true`.** Turning it off is a real change, not a
  restatement of the default. It also gates OTel export, which needs both flags true.
 - **Vibe reads `.agents/skills/` and `AGENTS.md` already.** The directory
  `wikitool instructions sync` publishes is a project-scope skill source for Vibe, so this
  repository needs no adaptation to be worked on with it - only a trusted folder.
 ## Whether it runs at all
 The default depends on how this tree got here, not on a single hard-coded switch -
 [tools/chemenu/telemetry/policy.py](tools/chemenu/telemetry/policy.py) is the one place that
 resolves it, so `wikitool doctor`, the writer and the MCP server's start-up guard all answer the
 same question the same way:
 | Installation form | Default | Marker |
 |---|---|---|
 | Git clone of this repo (dev checkout) | **on** (opt-out) | No `.wikitool-release.json` |
 | An instance installed from a release, and every clone of its own repository | **off** (opt-in) | `.wikitool-release.json` present |
 The form is read off `.wikitool-release.json`, the same stamp `version check`, `dist upgrade` and
 `version notes` already use to tell a distribution from the repo it came from - present means an operator never
 asked for telemetry, absent means this is the dev checkout the stack ships from, where the traces
 are its own measuring instrument (the rest of this file). An instance commits the stamp with its
 first `publish`, so a clone of it on a second machine carries the stamp and defaults off too - it
 is a consuming instance, not a measuring stand.
 **Turning it on for a distributed instance** is a per-checkout `.wikitool-telemetry.json` at the
 repo root, gitignored like `.wikitool-remotes.json` and for the same reason: the consent to write
 cleartext prompts to *this* disk belongs to the checkout, not the corpus, so a second clone must
 not inherit it silently. `instructions/setup-instance.md`'s Telemetry decision point asks for it
 during setup; nothing writes it automatically.
 ```json
 { "enabled": true, "max_session_bytes": 5242880, "keep_sessions": 250 }
 ```
 All three keys are optional. `WIKI_TRACE` still overrides `enabled` in both directions and beats
 the file, exactly as it always has.
 **Two independent quantity caps, both enforced fail-silent in `emit()`** - never in
 `write_event()`, which the test suite calls directly to exercise the format without the policy
 wrapped around it:
 - **A byte cap per session trace** (default 5 MiB, `max_session_bytes` / `WIKI_TRACE_MAX_SESSION_BYTES`),
  checked with one `stat` before every append. Once a trace is at or over the cap, further calls
  in that session write nothing except a single `telemetry.limit` event - elected by the same
  single-writer trick `session.start` uses (an exclusive-create on a `.limit` marker file), so a
  trace that was cut off is distinguishable from one whose writer simply crashed.
 - **Retention by session count** (default 250, `keep_sessions` / `WIKI_TRACE_KEEP_SESSIONS`),
  applied once, right before a brand-new session directory is created - never per event, and
  never against the session doing the creating. It deletes exactly `trace.jsonl` and `.limit`
  from the oldest directories beyond the cap and only `rmdir`s one once it is empty; nothing
  under `reports/` is ever removed in bulk.
 The default of 250 is chosen above what this repo's own checkout has accumulated as of
 2026-09-10 (231 session directories, well under 400 KiB total) - the cap starts biting on future
 growth, not on the existing history.
 ## What never reaches a trace
 Prompts and assistant replies **are** recorded in cleartext, locally. A failure taxonomy
 cannot be read out of hashes, and building one is the first phase of any eval work. Four
 guards make that defensible, all of them in
 [tools/chemenu/telemetry/scrub.py](tools/chemenu/telemetry/scrub.py) so there is one
 place to audit:
 1. **Secret scrubbing** - tokens, keys, `Authorization:` headers and `SECRET=` assignments are
   replaced with `[REDACTED:<type>]`. Pattern-based and therefore best effort.
 2. **A content cap** - 60 KiB per attribute, with a `[TRUNCATED n chars]` marker.
 3. **A kill switch** - `WIKI_TRACE_CONTENT=0` keeps only `<field>_length` and
   `<field>_sha256`. The digest is computed either way, so traces stay comparable.
 4. **`raw/` contents never enter a trace at all.** That text is data, not instruction
   ([AGENTS.md](AGENTS.md) invariant 4), and a trace gets read back later. Callers record a
   path and a digest.
 Nothing leaves the machine. `reports/` is gitignored, no exporter is configured, and where a
 vendor offers one it is off: Mistral's `enable_otel` ships prompts to Mistral Studio, so this
 repo leaves it - and `enable_telemetry` - `false`. Claude Code's and Copilot's content gates
 may only be enabled against a collector you run yourself.
 | Variable | Effect |
 |---|---|
 | `WIKI_TRACE` | `0`/`1` overrides on/off in either direction, beating both the installation-form default and `.wikitool-telemetry.json` - see § Whether it runs at all |
 | `WIKI_TRACE_DIR` | Write traces somewhere other than `reports/telemetry/` |
 | `WIKI_TRACE_CONTENT=0` | Lengths and digests instead of text |
 | `WIKI_TRACE_MAX_CONTENT` | Per-attribute cap in characters |
 | `WIKI_TRACE_MAX_SESSION_BYTES` | Per-session trace byte cap (default 5 MiB) - overrides `.wikitool-telemetry.json`'s `max_session_bytes` |
 | `WIKI_TRACE_KEEP_SESSIONS` | How many session directories retention keeps (default 250) - overrides `.wikitool-telemetry.json`'s `keep_sessions` |
 | `WIKITOOL_SESSION_ID` | The join key, and the directory a trace lands in |
 ## Evaluation levels
 Ordered by oracle strength - hard checks first, judgment last.
 | Level | Oracle | What it measures | Status |
 |---|---|---|---|
 | **L0** Pipeline | hard | A wiki the tools built themselves lints clean, and the catalog is a fixed point | **done** - `tools/chemenu/tests/test_pipeline_l0.py` |
 | **L1** Artifact scorecard | hard | Counters from `lint`'s own checks: hard errors and advisories, page count | **done** |
 | **L2** Trajectory | hard | Rules over the trace: was a refused call repeated, was a gate flag passed unearned, did a page change go unlogged | **done** |
 | **L3** Task evals | medium | Gold set: question → expected cited pages; ingest fixture → expected page titles. Scored by set overlap | needs the runner |
 | **L4** Rubric / judge | soft | Prose quality, cramming, tone | **out of scope** until a failure taxonomy exists |
 Evaluation results are statistical, not binary: a case runs several times and reports a pass
 rate with its variance, because sampling is not deterministic. A single failure is not a
 merge blocker; a regression against a baseline is.
 ### L0 lives in pytest, not in a separate harness
 It runs the CLI against an empty wiki in-process and asserts that `new` → write → `xref` →
 `index rebuild` leaves a tree `lint` calls clean, and that rebuilding the catalog again changes
 nothing on disk. That is a hard oracle over the compiler, which is what the test suite is for -
 giving it its own runner would have duplicated the suite to no end.
 One behaviour it pins is easy to mistake for a defect: **a scaffolded page does not lint
 clean**. `new` writes placeholder wikilinks for the author to replace, so a page that was
 created but not yet written reports broken links, and its `TODO`-only sections as the advisory
 *Unfilled Template Sections*. That is the scaffold saying it is unfinished.
 ### How much of the stack the suite reaches
 Coverage is measured in CI - `pytest --cov`, config in `tools/.coveragerc`, HTML and XML
 uploaded as the `coverage-<run id>` artifact of every run.
 **Fetch that artifact from the run's own page, not from the API**: `upload-artifact@v3` writes
 through the older artifact API, and the Actions artifact REST endpoints answer `total_count: 0`
 for a run whose artifact the run page offers for download. The upload works; only the listing
 does not see it. Do not re-derive this, and do not read the empty list as a failed upload.
 It is enforced at a floor of **85%** (`fail_under` in `tools/.coveragerc`), which is what a red
 suite from this axis means: coverage actually fell, not that a wrapper was added. The floor was
 set only after the number had been watched - it was deliberately held back for exactly that, and
 the two points between 85 and the measured 87.0% are the room the taxonomy below asks for. A
 threshold at the measured number goes red on the next thin Typer wrapper, and a threshold that
 goes red for a non-reason gets lowered rather than earned.
 **Measured 2026-09-04, stack 4.7.1: 87.0% of 6498 statements across `chemenu/`, 975 tests** -
 CI run 163. The first measurement, at stack 1.8.1 on 2026-08-31, was 86.9% of 5105 statements
 over 730 tests (CI run 87). Both are what CI reported, never a local run: the local number
 preceding a release measures a tree that is one commit short of the published one.
 The pair says more than either number does. Between them the measured code grew by a quarter
 and the suite by a third, and the quota moved by a tenth of a point - which is the observation a
 threshold was waiting for, rather than the total itself. Reproduce either with
 `cd tools && .venv/bin/python -m pytest -q --cov` (needs `pytest-cov`, which is CI-only and
 deliberately absent from `tools/requirements.txt` - an instance runs the wiki, it does not
 measure this suite).
 The total stays the least interesting number here. What the report is for is *which* modules sit
 low, and three kinds have to be told apart before any of it turns into work:
 - **Thin Typer wrappers**, where the logic lives beside them and is tested there:
  `eval_cmd.py` (36%), `types_cmd.py` (40%), `search.py` (49%), `cli.py` (54%),
  `links_cmd.py` (61%). Low coverage on a wrapper is evidence of a good cut, not of a missing
  test - `search.py`'s uncovered block is its command body alone, while the backends under
  `chemenu/search/` that do the work sit between 91% and 98%.
 - **Code that reaches the network or the filesystem's outside**, where the interesting half is
  already injectable and tested through the seam: `version.py`'s `fetch_latest()` takes a
  `fetcher` parameter for exactly that. The real `urllib` lines are exercised too, but only
  against a local `http.server` in `test_dist_upgrade.py` (`dist upgrade --latest`) - never
  against a real feed, which stays uncovered on purpose.
 - **Genuine gaps**, where uncovered lines are logic nobody exercises: `provenance_cmd.py`
  (44%), `migrate_cmd.py` (65%), `type_resolver.py` (79%). This is the list worth reading, and
  the only one of the three that has not moved while everything around it did:
  `provenance_cmd.py` sits where it sat, and `migrate_cmd.py` fell from 71% because it grew and
  its new lines arrived untested. The floor freezes this; it does not close it.
 <!-- dist:strip-start -->
 Closing it is Gitea #51. (Kept behind a strip marker: the pointer resolves in the origin repo
 and nowhere else.)
 <!-- dist:strip-end -->
 ## Scoring a session
 ```bash
 tools/wikitool eval sessions              # which sessions have a trace
 tools/wikitool eval score                 # score this shell's session
 tools/wikitool eval score --session telemetry-p1 --save
 ```
 Both are read-only and exempt from the Iteration Budget Gate: reading back what a session did
 is not iteration on the wiki, and charging for it would discourage checking one's own work.
 **L1** re-runs `lint`'s checks in-process and reports its counters. It shares the definition
 of what counts as a hard error with `lint --fail-on-error` - one constant, `HARD_ERROR_KEYS`,
 so a run can never pass its score while lint refuses it.
 **L2** checks five rules, and each one restates an invariant the code cannot enforce
 in-process. A gate can refuse a call; nothing stops an agent from calling again with the
 gate's own flag. That gap is the whole point:
 | Rule | Invariant | Severity |
 |---|---|---|
 | `refusal-not-retried` | A refused call, repeated unchanged, is the loop the gate exists to break | error |
 | `gate-not-self-opened` | `--yes`/`-y` no longer exist at all; `--override-budget` is for a human to pass after a refusal; `--force` never | error |
 | `content-change-logged` | A publish that changes `kb/` pages needs a `log append` in the same session | advisory |
 | `clearance-was-asked-for` | A `gate.cleared` token must match one some earlier `gate.refused` issued - catches an invented token, and one reused from a different changeset | error |
 | `clearance-ended-the-turn` | No `wikitool.call` between a clearance request (exit 42) and the next `prompt.submitted` - skipped, not failed, on a harness that cannot report `prompt.submitted` | error |
 New rules belong here only when a real trace shows a real failure. Inventing checks from the
 contract text produces a score that improves while behaviour does not - the failure mode the
 [phase-gate note](commonplace/kb/notes/evaluation-automation-is-phase-gated-by-comprehension.md)
 describes. The first three were chosen because each is a refusal an agent can talk its way
 around; the last two carry the load for the Mass-Update Gate's clearance mechanism
 (2026-08-28), which deliberately enforces very little in-process - see below.
 A rule can now report a third state besides pass/fail: **skipped**, meaning this trace cannot
 answer the question at all (e.g. `gate-refusal-ended-the-turn` on a harness with no prompt
 hook). Skipped reads as neither a pass nor a violation - `scorecard.render_markdown` marks it
 `skip`, distinct from `ok`/`warn`/`FAIL`, and `score()["violations"]` never includes a skipped
 rule regardless of severity.
 ### A worked example, and where the check moved to
 Scoring the session that shipped the telemetry layer itself used to report a failure:
 ```
 FAIL gate-not-self-opened
  call=publish --message "tools: session traces …" --yes, reason=no mass-update refusal preceded it
 ```
 That finding was true and benign at the same time. The change was 17 files, the file list was
 shown, and a human approved it - but the approval happened in conversation, and `--yes` went
 out on the first attempt, so the gate never got to refuse anything. The documented path had the
 refusal first, and the trace records tool calls, not conversations.
 Three sessions did some version of this before the mechanism changed rather than the procedure.
 The interesting part is *which* half changed. The obvious fix - make the gate impossible to open
 without independent proof of a human - was built first: a ticket bound to the changeset, redeemed
 only after a `prompt.submitted` event and a `wikitool approve` typed in a second terminal. It
 worked, and it was unusable: on a harness driving `wikitool` through a shell tool, the agent
 cannot produce the turn signal and the human is asked to leave the conversation to approve
 anything at all. A gate nobody can pass is not a safe gate, it is an abandoned one.
 So the enforcement got cheap and the *verification* got real:
 - **In-process, `publish` enforces only what it can do honestly.** Exit 42 says "a human must see
  this"; `--confirm <token>` says "here is what they saw", and the token digests the file list so
  it cannot silently cover a different one. None of that proves a human was involved, and the
  code says so in as many words.
 - **The trace answers the question the tool cannot.** `clearance-ended-the-turn` looks for a
  `wikitool.call` between an exit-42 call and the next `prompt.submitted` - which is exactly the
  "refused, then confirmed in the same breath" shape all three incidents had, and is invisible to
  any single call. `clearance-was-asked-for` catches a token that no refusal ever issued.
 This is the loop the whole file is about, run to its conclusion: a rule that only a trace could
 check, a trace that showed it being broken three times, a mechanism rebuilt because no procedural
 fix survived - and then the check itself relocated to the layer that can actually see it.
 **What this still cannot see:** an agent that receives the exit-42 output, does not relay it, and
 passes the token anyway *after* the user happens to say something unrelated. `prompt.submitted`
 proves a turn boundary, not that the output was relayed or that the reply meant yes. That gap is
 recorded rather than papered over; closing it needs the harness to report what the agent actually
 said, which no adapter here does yet.
 That gap stopped being hypothetical within the hour. The first agent to receive the new gate -
 the one that had just written the paragraph above - answered the user with a file *count* and a
 pointer to "the output above", which on this harness the user could not see: a command's stdout
 goes to the agent's context, not to anyone's screen. Nothing in the trace distinguishes that from
 a correct relay, and nothing will. The response was to fix the half that *is* fixable, the
 wording: the message now says "THE USER CANNOT SEE THIS OUTPUT", asks for the paths to be copied
 into the reply, and names the near-misses that do not count (a count, a summary, "the output
 above"). An instruction that conflates printing with showing reads as already satisfied by the
 text existing - which is a general lesson about writing for agents, not a detail of this gate.
 ## Using it today
 Tracing is on by default and needs no setup. Scope a session and read what it produced:
 ```bash
 export WIKITOOL_SESSION_ID="my-task"
 tools/wikitool search "amd-pstate"
 tools/wikitool lint --fail-on-error
 # what did that session do?
 jq -r '[.ts, .source, .event, (.attrs.command // .attrs.tool_name // "")] | @tsv' \
  reports/telemetry/my-task/trace.jsonl
 # how well did it do it?
 tools/wikitool eval score --session my-task
 ```
 Feed a harness hook payload in by hand, without writing anything:
 ```bash
 echo '{"session_id":"x","hook_event_name":"post_tool","tool_name":"bash"}' \
  | tools/trace_ingest.py --source mistral-vibe --dry-run
 ```
 ## Status
 | Piece | State |
 |---|---|
 | Event schema, scrubber, writer | done - `tools/chemenu/telemetry/` |
 | `wikitool.call` on every command | done - one hook point in `cli.py`, next to the budget gate |
 | `gate.refused` (loop-breaker, iteration budget, mass-update) | done |
 | `publish.commit` | done |
 | Hook entry point | done - `tools/trace_ingest.py`, mappings for all three hook-capable harnesses |
 | Copilot CLI hooks | done - `.github/hooks/wiki-trace.json` |
 | VS Code chronicle import | done - `tools/import_chronicle.py` |
 | Mistral Vibe hooks | done - `.vibe/hooks.toml`, `.vibe/config.toml` |
 | Session header seeded on every trace | done - a trace declares its own `completeness` even without a session hook |
 | Scoring L1 + L2 | done - `wikitool eval score` |
 | L0 pipeline check | done - in the test suite |
 | Claude Code hooks | **partial** (2026-08-28) - `.claude/settings.json` wires `UserPromptSubmit` (the turn boundary `clearance-ended-the-turn` scores against) plus a `permissions.ask` rule on the `--confirm` form of `publish`; `PreToolUse` verified unable to force a prompt over `permissions.allow`, see "Claude Code" above |
 | Claude Code OTel | not started; not verified against the live CLI yet |
 | Agent runner (`eval run`) and L3 | designed below, not built |
 ## The agent runner, and why it is not here yet
 Scoring reads what a session left behind. The missing half is *starting* one: a runner that
 launches a harness against a task, several times, and reports a pass rate. What it has to do is
 no longer guesswork - the adapter work settled most of it:
 - **Give each run a copy of the repository, not a fixture directory.** `config.ROOT` is derived
  from `chemenu/config.py`'s own location, so `wikitool` cannot be aimed at another tree
  from outside. An agent case therefore needs a worktree or a clone, where the tool sits inside
  the tree it edits. (A *fixture* directory works fine in-process, which is why L0 is a test.)
 - **Give each run its own HOME**: `VIBE_HOME`, `COPILOT_HOME`, plus `WIKI_TRACE_DIR` and
  `WIKITOOL_SESSION_ID`, so state, trust decisions and traces cannot leak between runs.
 - **Never launch Vibe without `--agent`.** Its programmatic mode falls back to `auto-approve`
  when no agent is named, and does not ask about folder trust. The runner must refuse rather
  than inherit that default.
 - **Record a run manifest**: harness and version, model, git SHA, and hashes of `AGENTS.md`,
  the published skills and the fixture. Without it a pass rate cannot be compared to anything.
 What is missing is not the design but the ability to check it. No provider credentials are
 configured on this machine - Vibe's providers declare an `api_key_env_var` and none of those
 variables is set - so a live run cannot be executed, let alone verified. Writing it anyway
 would repeat exactly the mistake the Vibe adapter avoided: the hook format there was wrong in
 the documentation and only the installed CLI showed it. A runner written against an unverified
 mental model of three harnesses would be worse.
 Open questions: whether Claude Code has a redirectable config directory (only `--settings` is
 documented), and whether the scrubber's own patterns are enough or a dedicated secret scanner
 belongs in the verification step.

 # MCP-Leseserver installieren
 Dieses Dokument richtet sich an Menschen. Es beschreibt, wie der MCP-Leseserver eines Chemenu-
 Wikis lokal läuft, wie ein Client ihn einbindet, und wie er hinter einer Authentifizierung
 erreichbar wird. Der agent-seitige Betriebsablauf steht in
 [instructions/mcp-read-server.md](instructions/mcp-read-server.md); die vollständige
 Kommandoreferenz in [tools/CONTRACT.md](tools/CONTRACT.md).
 **Was der Server ist.** Ein zweiter Konsument desselben Kerns, nicht ein zweites Programm. CLI
 und Server rufen dieselben Funktionen auf; ein Golden-Test hält ihre Ausgaben gegeneinander.
 Was `tools/wikitool search --json` liefert, liefert das MCP-Tool `search` auch — plus den
 Commit, aus dem die Antwort berechnet wurde.
 **Was er nicht ist.** Kein Schreibpfad nach `kb/`. Es gibt kein Tool, das eine Seite anlegt,
 ändert oder publiziert — nicht weil eine Liste gefiltert wird, sondern weil der Server nichts
 unter `tools/chemenu/commands/` importiert. Die Funktionen sind aus diesem Prozess heraus nicht
 erreichbar. Optional gibt es ein sechstes Tool, `submit` (Schritt 7): es schreibt, aber nur in
 eine Quarantäne, die kein anderer Befehl liest — eine Positiv-Liste im Code statt einer
 Abwesenheit, und ein Mensch entscheidet über jede Beförderung daraus.
 ## Voraussetzungen
 - Eine funktionierende Instanz nach [INSTALL.md](INSTALL.md) — inklusive `tools/.venv` und
  `ripgrep`
 - Python 3.11 oder neuer (wie die CLI)
 ## Schritt 1: Abhängigkeit installieren
 Sie liegt bewusst nicht in `tools/requirements.txt`. Eine Instanz, die nur die CLI benutzt, soll
 dafür nicht pydantic, starlette, uvicorn und cryptography mitinstallieren müssen.
 ```bash
 tools/.venv/bin/pip install -r tools/requirements-mcp.txt
 ```
 ## Schritt 2: Lokal starten (stdio)
 `stdio` ist der Weg zum Ausprobieren und für einen Client auf derselben Maschine: ein Prozess
 pro Konsument, lokal gestartet, kein Netzwerk.
 ```bash
 WIKI_TRACE=0 tools/.venv/bin/python -m chemenu.mcp
 ```
 Der Prozess spricht MCP über stdin/stdout und gibt für sich genommen nichts aus — das ist
 richtig so. Gestartet wird er normalerweise nicht von Hand, sondern vom Client (Schritt 3).
 **Das `WIKI_TRACE=0` oben ist in einer ausgelieferten Instanz meist redundant, aber trotzdem
 richtig.** Telemetrie-Default hängt vom Installationsweg ab
 ([INSTALL.md](INSTALL.md) § Konfiguration): in einer per `dist export` ausgelieferten Instanz
 steht er auf **aus**, in einem Git-Clone dieses Repos (Testbett/Demo) auf **an**. Der Server
 prüft nicht `WIKI_TRACE` direkt, sondern denselben `chemenu.telemetry.policy`, den auch
 `wikitool doctor` und der Writer befragen - läuft Telemetrie danach, **verweigert der Server den
 Start**, statt still umzuleiten:
 ```
 ERROR Telemetry is on and would write into the served checkout (...). Set WIKI_TRACE=0,
 or point WIKI_TRACE_DIR outside the corpus.
 ```
 Beide Auswege sind gleichwertig: `WIKI_TRACE=0` schaltet ab, `WIKI_TRACE_DIR=/var/log/chemenu`
 lenkt um. Der Grund steht in Schritt 6 — der Sync darf `reports/` wegräumen. Das explizite
 `WIKI_TRACE=0` in den Befehlen dieses Dokuments bleibt der sichere Default: es ist korrekt, egal
 welchen Weg die bediente Instanz genommen hat, und macht die Prüfung oben gegenstandslos, statt
 sich auf den Installationsweg zu verlassen.
 ## Schritt 3: Einen Client einbinden
 Die Konfiguration folgt der üblichen MCP-Client-Form. Absolute Pfade, weil der Client kein
 Arbeitsverzeichnis erbt:
 ```json
 {
  "mcpServers": {
    "chemenu": {
      "command": "/pfad/zur/instanz/tools/.venv/bin/python",
      "args": ["-m", "chemenu.mcp"],
      "cwd": "/pfad/zur/instanz/tools",
      "env": {
        "WIKI_TRACE": "0",
        "CHEMENU_ROOT": "/pfad/zur/instanz"
      }
    }
  }
 }
 ```
 `CHEMENU_ROOT` sagt, **welches** Wiki bedient wird. Ohne die Variable nimmt der Server den
 Checkout, in dem das Paket selbst liegt — für eine einzelne Instanz reicht das, aber wer mehrere
 Korpora hat, setzt sie besser immer.
 Danach kennt der Client fünf Werkzeuge, und optional ein sechstes:
 | Tool | Was es beantwortet |
 |---|---|
 | `search` | Seiten in `kb/` nach Text, nach Frontmatter (`!sources`, `tags~k8s`) oder beidem |
 | `types` | Welche Seitentypen dieses Wiki kennt |
 | `describe_type` | Der vollständige Vertrag eines Typs: Felder, Pflichtangaben, Enums |
 | `lint` | Strukturelle Befunde: kaputte Wikilinks, Waisen, Index-Drift, Schema-Lücken |
 | `status` | Momentaufnahme: Seitenzahl, Verteilung auf Collections, Befundzahlen |
 | `submit` *(optional, Schritt 7)* | Reicht ein Dokument in die Prüf-Warteschlange ein — kein Schreibpfad nach `kb/`, nur in eine Quarantäne |
 ## Schritt 4: Ausgeliefert starten (streamable HTTP)
 Der Transport für den Betrieb, und der einzige, vor den sich ein Reverse Proxy setzen kann.
 ```bash
 WIKI_TRACE=0 CHEMENU_ROOT=/srv/chemenu \
  tools/.venv/bin/python -m chemenu.mcp \
    --transport streamable-http --host 0.0.0.0 --port 8000
 ```
 Der Endpunkt ist dann `http://<host>:8000/mcp`.
 `--host 0.0.0.0` ist bewusst nicht der Default. Ohne die Angabe bindet der Server auf Loopback,
 was lokal richtig und im Container falsch ist — dort muss der Proxy ihn erreichen können. Wer
 `0.0.0.0` setzt, muss also auch dafür sorgen, dass davor etwas steht (Schritt 5).
 `sse` wird nicht angeboten. Es ist der abgelöste Remote-Transport; jetzt darauf zu bauen
 verschiebt den Wechsel nur.
 ## Schritt 5: Authentifizierung davor
 **Der Server authentifiziert nicht selbst, und das ist Absicht.** Nicht sauber
 authentifizierte Zugriffe sollen den Python-Prozess gar nicht erst erreichen. Die
 Authentifizierung ist eine Traefik-ForwardAuth-Middleware:
 > **<https://gitea.nehmer.net/torben/gitea-mcp-forward-auth>**
 Kurz, was sie tut: sie prüft `Authorization: Bearer <token>` gegen SHA-256-Hashes erlaubter
 Tokens, antwortet `200` bei gültigem und `401` bei fehlendem oder falschem Token, und hält
 `GET /healthz` immer offen. Klartext-Tokens liegen weder in der Konfiguration noch im Log — nur
 Hashes und ein kurzer Fingerprint. Konfiguriert wird sie über
 `AUTH_PROXY_TOKEN_HASHES_DIR` (ein Verzeichnis, eine Datei je Token-Hash — passend für ein
 Kubernetes-Secret-Volume) oder `AUTH_PROXY_TOKEN_HASHES` (kommagetrennte Liste). Einzelheiten,
 Referenzmanifeste und ein Testskript stehen im README dort.
 Einen Token-Hash erzeugen:
 ```bash
 echo -n "mein-token" | sha256sum | awk '{print $1}'
 ```
 **Rate Limiting gehört an dieselbe Stelle** — vor den Prozess, neben die Authentifizierung.
 Nicht in den Iteration Budget Gate: der begrenzt eine *Agenten-Session* am unbemerkten Iterieren
 über den Wiki-Zustand, weshalb Retrieval von ihm ausgenommen ist. Ihn als Rate Limiter zu
 benutzen würde ihn dazu verwässern.
 **Ist der `submit`-Pfad scharf geschaltet (Schritt 7), kommt eine zweite Pflicht hinzu:** die
 Middleware muss den konfigurierten Identitäts-Header (Default `X-Forwarded-User`) selbst setzen
 und eine vom Client mitgeschickte Kopie verwerfen. Der Prozess vertraut diesem Header als Wert
 für `submitter` — ein Header, den der Client selbst setzen dürfte, wäre keine Identität, sondern
 eine Behauptung.
 ## Schritt 6: Den Korpus aktuell halten
 Der Server liest den Arbeitsbaum. Ein veralteter Checkout antwortet selbstbewusst falsch —
 deshalb trägt **jede Antwort den Commit**, aus dem sie berechnet wurde:
 ```json
 { "commit": "<40-stelliger SHA>", "as_of": "<ISO-8601, UTC>", "count": 3, "...": "..." }
 ```
 Aktuell gehalten wird der Baum durch Polling, aus einem Timer neben dem Server:
 ```bash
 git -C "$CHEMENU_ROOT" fetch --quiet origin && \
  git -C "$CHEMENU_ROOT" reset --hard --quiet origin/main
 ```
 Polling statt Webhook, weil es keinen eingehenden Endpunkt und keine Signaturprüfung braucht —
 eine kleinere Angriffsfläche als das, was es optimieren würde.
 `reset --hard` ist dabei tragend und keine Bequemlichkeit: der Korpus-Cache verwendet einen
 Parse wieder, solange der Commit gleich bleibt, und cacht einen **schmutzigen Baum überhaupt
 nicht**. Ein abgedrifteter Checkout antwortet also zwar richtig, parst aber bei jeder Anfrage
 neu — und stempelt jede Antwort mit `"commit": null`, weil sie keiner Revision entspricht.
 ## Schritt 7: Optional - den `submit`-Pfad freischalten
 Ohne diesen Schritt existiert `submit` als Tool nicht — nicht ungenutzt, sondern nicht
 registriert. Die Datei `.wikitool-upload.json` im bedienten Korpus schaltet ihn frei:
 ```json
 {
  "schema": 1,
  "identity_header": "X-Forwarded-User",
  "max_bytes": 10485760,
  "allowed_extensions": [".md", ".txt", ".pdf", ".html", ".csv", ".json", ".png", ".jpg"],
  "quota": { "submissions_per_day": 20, "bytes_per_day": 52428800 }
 }
 ```
 Jedes Feld ist Pflicht, keines hat einen eingebauten Default außer `identity_header` — eine
 fehlerhafte Datei ist ein Startfehler des Servers, kein „keine Beschränkung": das Ziel ist
 absichtlich die sichere Richtung. `identity_header` muss der Header sein, den Schritt 5 oben
 gerade eben *scharf gemacht* hat (Middleware setzt, Client-Kopie verworfen) — sonst wird jede
 Einreichung mangels Identität abgelehnt.
 Eingereichte Dateien landen in `mcp-upload/<id>/`, gitignored, von keinem anderen Kommando
 gelesen. Ein Mensch prüft und befördert sie über `wikitool upload accept <id> --confirm <token>`
 (Exit 42 beim ersten Versuch, mit Manifest und Token in der Ausgabe) oder verwirft sie über
 `wikitool upload reject <id> --reason "<warum>"` — siehe
 [instructions/ingest-queue.md](instructions/ingest-queue.md) für den Prüfablauf. Beide Kommandos
 laufen im selben Checkout wie der Server, nicht im Prozess selbst.
 ## Verifikation
 Läuft es? Der schnellste Test ohne Client — startet den Server über stdio, listet die Tools und
 stellt eine Frage:
 ```bash
 cd tools && WIKI_TRACE=0 .venv/bin/python - <<'EOF'
 import asyncio, os
 from mcp import ClientSession, StdioServerParameters
 from mcp.client.stdio import stdio_client
 async def main():
    params = StdioServerParameters(
        command=".venv/bin/python", args=["-m", "chemenu.mcp"],
        env={"WIKI_TRACE": "0", "PATH": os.environ["PATH"]},
    )
    async with stdio_client(params) as (r, w):
        async with ClientSession(r, w) as s:
            await s.initialize()
            print("Tools:", [t.name for t in (await s.list_tools()).tools])
            out = await s.call_tool("status", {})
            d = getattr(out, "structuredContent", None) or out.structured_content
            print("Seiten:", d["pages"], "| Commit:", d["commit"])
 asyncio.run(main())
 EOF
 ```
 Erwartete Ausgabe, sinngemäß:
 ```
 Tools: ['search', 'types', 'describe_type', 'lint', 'status']
 Seiten: 176 | Commit: 576df2cdddc96614a7e6641e562022d52112d411
 ```
 Gegen die CLI gegenprüfen — beide müssen dieselbe Antwort geben:
 ```bash
 tools/wikitool search "<begriff>" --json
 ```
 ## Troubleshooting
 **`ERROR Telemetry is on and would write into the served checkout`** — erwartetes Verhalten,
 kein Fehler in der Installation. `WIKI_TRACE=0` setzen oder `WIKI_TRACE_DIR` aus dem Korpus
 heraus zeigen lassen (Schritt 2).
 **`ModuleNotFoundError: No module named 'mcp'`** — Schritt 1 fehlt, oder der Client startet ein

 **`"commit": null` in jeder Antwort** — der bediente Baum hat uncommittete Änderungen. Entweder
 läuft der Sync nicht, oder etwas schreibt in den Korpus, das dort nichts zu suchen hat. Die
 fünf Lesewerkzeuge schreiben nie, und `submit` (falls scharf) ausschließlich nach
 `mcp-upload/` — gitignored, also selbst kein Grund für `"commit": null`; ein Test prüft das,
 indem er alle Tools aufruft und Dateibaum, `HEAD` und `git status --porcelain` vorher/nachher
 vergleicht.
 **`commit` nennt eine alte Revision** — der Sync aus Schritt 6 läuft nicht.
 **Der Server antwortet anders als `wikitool`** — das ist ein Defekt, keine
 Konfigurationsdifferenz: beide gehen durch dieselben Funktionen, und ein Golden-Test hält sie
 zusammen. Zuerst prüfen, ob beide auf denselben Root zeigen; `CHEMENU_ROOT` ist leicht für einen
 von beiden gesetzt und für den anderen nicht.
 **Von außen nicht erreichbar** — ohne `--host 0.0.0.0` bindet der Server auf Loopback
 (Schritt 4). Wenn er dann erreichbar ist, aber jeder Aufruf `401` bekommt, arbeitet die
 Middleware aus Schritt 5 korrekt und das Token stimmt nicht.

 ## Version und Updates
 Jede Instanz trägt die Version des **Stacks** (Werkzeuge, Typen, Instruktionen, Contracts) -
 nicht die ihres Inhalts. Sie steht in `VERSION`, daneben `.wikitool-release.json` mit Herkunft
 und Exportdatum des Releases.
 ```bash
 tools/wikitool version         # was läuft hier, und woher kommt es
 tools/wikitool version check   # gibt es ein neueres Release?
 ```
 `version check`, `version notes` und `dist upgrade --latest` sind die einzigen Befehle, die
 ins Netz gehen, und alle drei fragen denselben Release-Feed der Ursprungs-Instanz
 (`$WIKITOOL_UPDATE_URL` überschreibt; sonst der Wert aus dem Stamp). `version check` ist dafür da;
 `version notes` greift nur dann darauf zurück, wenn die lokale `CHANGES.md` den Eintrag nicht
 hat - auf einer Instanz also immer, siehe unten - und sagt vorher auf stderr, welche URL es
 fragt; `dist upgrade` fragt den Feed nur, wenn `--latest` dasteht, und lädt dann auch das Release
 herunter (siehe „Eine Instanz aktualisieren"). Ein nicht erreichbarer Feed wird als Fehler
 gemeldet - **nie** als „aktuell" und nie als „keine Notes".
 **Was die Versionsnummer aussagt:** kompatibel ist, was in der *linkesten von Null
 verschiedenen Stelle* übereinstimmt. `0.1.3 → 0.1.4` ist ein sicheres Update, `0.1.3 → 0.2.0`
 nicht, und ab `1.0.0` liest sich dieselbe Regel als das gewohnte „MAJOR bricht". `version check`
 sagt das direkt (`state: update` vs. `state: migration`).
 Was diese Stelle beantwortet, ist **ob die neue Version ein Drop-in-Ersatz ist** - ob sich die
 Maschinerie einfach darüberkopieren lässt und ob die alte danach noch zurückkann. Ob *Inhalt*
 migriert werden muss, ist eine **zweite, unabhängige Frage**. Ein MAJOR-Sprung kann eine leere
 Migrationskette haben und trotzdem Handarbeit verlangen: umbenannter Release-Feed, umbenanntes
 Artefakt, umbenannter Import- oder Kommandoname, geänderte Envvar - `kb/` bleibt dabei
 unangetastet, das Update ist trotzdem keins zum Drüberkopieren. Der Abschnitt „Sonderfall:
 Update von 1.x auf 2.0.0" unten ist genau dieser Fall.
 Deshalb stehen in den Release-Notes eines MAJOR zwei getrennte Zeilen, und beide sind vor dem
 Update zu lesen: **Breaking Change:** sagt, was aufhört zu funktionieren und was diese Instanz
 dagegen tun muss; **Migration:** sagt, ob und wie der Korpus umgeschrieben wird (`none required`,
 wenn nicht). `tools/wikitool version notes` druckt beide Zeilen - im Ursprungs-Repo aus der dort
 gefüllten `CHANGES.md`, auf einer ausgelieferten Instanz aus dem Release-Feed, weil die Instanz
 die Datei nur als Stub bekommt und ein Update sie nie überschreibt. Der Befehl fragt dabei immer
 das **neueste** Release: solange `VERSION` noch die alte Fassung nennt, antwortet er also mit
 einer anderen Version als der eigenen und sagt das auf stderr dazu. Ist der Feed nicht
 erreichbar, nennt die Fehlermeldung die Release-Seite, die `.wikitool-release.json` als
 `release_url` führt; `--offline` verlangt diesen Weg von vornherein.
 ### Eine Instanz aktualisieren
 Das Anwenden eines Updates schreibt in eine Instanz, die bereits Inhalt hat. Der Inhalt hat dabei
 eine **eigene Version**: `.wikitool-kb.json` sagt, in welcher Form die Seiten vorliegen,
 unabhängig davon, welche Maschinerie danebensteht. Genau dieser Unterschied ist der Zustand, in
 dem sich jede Instanz mitten im Upgrade befindet.
 **Die Durchführung selbst steht in `instructions/upgrade-instance.md`** - die Reihenfolge, was
 jeder Schritt entscheidet, wo die Agent-Sitzung neu gestartet werden muss, und die beiden Stellen,
 an denen heute Handarbeit nötig ist. Sie steht dort und nicht hier, weil sie von einer
 Agent-Sitzung ausgeführt wird; eine zweite Fassung derselben Schrittfolge an dieser Stelle wäre
 genau die Kopie, die irgendwann auseinanderläuft. Wer den Lauf selbst fahren will, liest dieselbe
 Datei.
 Was dieses Dokument beiträgt, ist die Entscheidung *davor* - welches Release, ob überhaupt, und
 wem die Instanz als Quelle vertraut - und zwei Sonderfälle, die die Instruktion nicht abdecken
 kann, weil es sie dort noch nicht gibt.
 **Das Release kommt mit einem Befehl.** `tools/wikitool dist upgrade --latest --expect <version>`
 fragt den Release-Feed, lädt Tarball und `.sha256` in ein Arbeitsverzeichnis, prüft den Tarball
 gegen die Summe und wendet ihn an; das Arbeitsverzeichnis verschwindet bei jedem Ausgang wieder,
 auch bei `--dry-run`. `<version>` ist die, die `version notes` gedruckt hat: der Feed kennt nur
 sein *neuestes* Release, und `--expect` verweigert den Lauf **vor** dem Download, wenn inzwischen
 ein neueres erschienen ist, statt es ungelesen einzuspielen. Beides zusammen entscheidet vor dem
 Download über „schon aktuell", Downgrade und Vor-Release (`-beta.N` braucht `--pre`); fehlt dem
 Release der Tarball oder die Summe, bricht der Befehl vor dem ersten Download ab und nennt die
 Release-Seite. Wer offline arbeitet oder einen Tarball vom Betreiber bekommen hat, gibt statt
 `--latest` weiter die Datei an (`dist upgrade <tarball>`).
 **Was die Prüfsumme leistet - und was nicht.** Die `.sha256` liegt beim selben Feed wie der
 Tarball. Sie schützt vor einer beschädigten Übertragung, nicht vor einem Feed, der selbst
 kompromittiert ist: die Echtheit eines Releases beruht auf dem Vertrauen in den Host, dessen
 Feed die Instanz fragt (`update_url` im Stamp). Es gibt keinen https-Zwang; wer einen
 `http://`-Feed konfiguriert, tut das bewusst. `$WIKITOOL_UPDATE_TOKEN` geht nur an Downloads
 auf demselben Host wie der Feed.
 **Beim ersten Sprung auf ein Release, das `--latest` kennt, gibt es die Option in der Instanz
 noch nicht** - die Instruktion, die dort steht, gehört zum Release, das die Instanz verlässt.
 Dann Tarball und `.sha256` einmal von der Release-Seite holen, nebeneinander ablegen und
 `dist upgrade <tarball>` geben; ab dem Release danach trägt die Instanz `--latest` selbst.
 **Beim ersten Sprung auf `4.5.0` oder höher gibt es `dist upgrade` in der Instanz noch nicht** -
 es kam erst mit `4.5.0`. Dann das Werkzeug aus dem entpackten *neuen* Tarball verwenden, gegen die
 alte Instanz gerichtet:
 ```bash
 tar -xzf chemenu-stack-<version>.tar.gz
 CHEMENU_ROOT="$PWD" chemenu-stack-<version>/tools/wikitool \
  dist upgrade chemenu-stack-<version>.tar.gz --dry-run
 ```
 `CHEMENU_ROOT` sagt dem Paket, auf welchen Korpus es zeigen soll (siehe § Konfiguration); ohne die
 Variable würde es den entpackten Tarball selbst für die Instanz halten. Ab dem zweiten Upgrade
 trägt die Instanz Kommando und Instruktion selbst, und der normale Weg greift.
 Was `dist upgrade` dabei genau tut, klassifiziert und verweigert, steht in
 [tools/CONTRACT.md](tools/CONTRACT.md) - einschließlich des vollständigen Fehlerkontrakts. Eine
 lokal veränderte Stack-Datei ist damit sichtbar, statt von Hand gegen die sha256-Summen im
 `files`-Block geprüft werden zu müssen - genau der Schritt, der vor `4.5.0` hier stand.
 `doctor` warnt, solange `kb_version` hinter `VERSION` zurückliegt und noch Migrationen offen
 sind. Einer Instanz, die älter ist als `.wikitool-kb.json`, fehlt die Datei ganz - dann einmalig
 `tools/wikitool migrate baseline <version>` aufrufen; geraten wird nichts.
 **Fallstricke.** Eine Instanz ohne lokale `.wikitool-release.json` (oder eine ohne `files`-Block,
 aus der Zeit vor `4.5.0`) hat für `dist upgrade` keine Basis, gegen die es eine lokale Änderung
 erkennen könnte, und verweigert den Tausch - dafür gibt es heute keine Reparatur.
 Mit `<tarball-oder-verzeichnis>` lädt der Befehl selbst nichts herunter; die Datei muss vorher
 von der Release-Seite geholt werden. Nur `--latest` lädt, und ein Tarball muss in beiden Fällen genau ein
 Top-Level-Verzeichnis enthalten - die Form, in der `.gitea/workflows/release.yml` es baut.
 Vor `4.5.0` stand hier ein rein manueller Ablauf (Maschinerie von Hand kopieren, `kb/CONTRACT.md`
 eingeschlossen, sha256-Vergleich von Hand). `dist upgrade` ersetzt genau diesen Teil; wer ihn
 dennoch von Hand nachvollziehen will oder muss (ein Werkzeug, das `wikitool` selbst nicht
 ausführen kann), findet die Dateiliste im `files`-Block der `.wikitool-release.json` und die
 Ausnahmen (`kb/CONVENTIONS.md`, `kb/*/COLLECTION.md`, `.wikitool-kb.json`) in
 [tools/CONTRACT.md](tools/CONTRACT.md)s `dist upgrade`-Datensatz (oder direkt:
 `tools/wikitool dist upgrade -h`).
 ## Konfiguration
 | Variable | Zweck | Fallback |
 |----------|-------|----------|
 | `WIKI_AUTHOR` | Override für den Autornamen neuer Source-Seiten | `git config user.name` - fehlt beides, bricht `new` mit `ERROR` ab |
 | `WIKITOOL_SESSION_ID` | Scopt das Iteration-Budget-Gate auf eine Aufgabe statt auf ein Terminal | Eine vom Harness selbst gesetzte Sitzungs-Variable, wo eine bekannt ist (z. B. `CLAUDE_CODE_SESSION_ID`), sonst die Parent-Process-ID (siehe [instructions/session-setup.md](instructions/session-setup.md)) |
 | `WIKITOOL_UPDATE_URL` | Release-Feed, den `version check` abfragt | Wert aus `.wikitool-release.json`, sonst der Feed der Ursprungs-Instanz |
 | `WIKITOOL_UPDATE_TOKEN` | Gitea-Token für den Release-Feed | keiner - gegen `torben/chemenu` nicht nötig, nur gegen einen Feed in einem nicht öffentlichen Repo |
 | `WIKITOOL_TASKS_CONFIG` | Pfad zu einer Tracker-Konfiguration, die `task`, `review` und `doctor` statt `.wikitool-tasks.json` lesen - um einen Checkout der Reihe nach gegen mehrere Tracker laufen zu lassen | die `.wikitool-tasks.json` im Repo-Root. Nennt die Variable eine Datei, die es nicht gibt, ist das ein Fehler und nie „kein Tracker konfiguriert" |
 | `CHEMENU_ROOT` | Auf welchen Korpus das Paket zeigt - für einen Aufrufer, der nicht im Checkout selbst liegt | der Checkout, in dem das Paket liegt (`tools/wikitool` verhält sich ohne die Variable unverändert) |
 | `WIKI_TRACE` / `WIKI_TRACE_DIR` | Telemetrie abschalten bzw. aus dem Arbeitsbaum heraus umlenken | Aus - siehe unten |
 | `WIKI_TRACE_MAX_SESSION_BYTES` / `WIKI_TRACE_KEEP_SESSIONS` | Byte-Deckel je Session-Trace bzw. wie viele Session-Verzeichnisse die Retention behält | 5 MiB je Session, 250 Verzeichnisse |
 **Gegen das Ursprungs-Repo braucht es kein Token.** `torben/chemenu` ist öffentlich lesbar;
 `version check`, `dist upgrade --latest` und die Installation funktionieren ohne Konfiguration.
 **Telemetrie ist in einer Instanz aus.** Jede Instanz trägt die `.wikitool-release.json` ihres
 Releases, und daran erkennt `chemenu.telemetry.policy`, dass niemand Telemetrie bestellt hat.
 Das gilt auch für jeden weiteren Klon der Instanz, weil die Datei mit dem ersten Commit ins Repo
 kommt. Nur ein Klon des Ursprungs-Repos zur Entwicklung trägt keine; dort sind die Traces das
 Messinstrument, mit dem der Stack sich selbst bewertet, und sie stehen auf **an**.
 Wer den Default umdrehen will, legt `.wikitool-telemetry.json` im Repo-Root an (pro Checkout,
 gitignored, kein `.template` - genau wie `.wikitool-remotes.json`):
 ```json
 { "enabled": true, "max_session_bytes": 5242880, "keep_sessions": 250 }
 ```
 Alle drei Schlüssel sind optional. `WIKI_TRACE` überschreibt `enabled` weiterhin in beide
 Richtungen und schlägt diese Datei. `wikitool doctor` meldet den aktuellen Zustand (an/aus,
 warum, und die Menge gegen beide Deckel); mehr dazu in [EVALS.md](EVALS.md) § "Whether it
 runs at all".
 **Tool-Pfade - schreibt der Preflight, nicht der Mensch.** `.wikitool-tools.json` im Repo-Root
 hält die absoluten Pfade von Python, git und ripgrep, so wie der Preflight sie auf diesem Rechner
 gefunden hat; `wikitool` startet git und rg von dort statt über `PATH`. Pro Checkout und
 gitignored - ein Pfad auf einem Rechner sagt über den nächsten nichts. Fehlt die Datei oder ist
 sie unvollständig, startet `tools/wikitool` nicht (Exit 42) und nennt den Preflight. Liegt ein
 Tool woanders, als der Preflight sucht, nennt man den Pfad mit
 `tools/preflight.sh --set rg=<pfad>` (PowerShell: `pwsh -NoProfile -ExecutionPolicy Bypass -File tools/preflight.ps1 --set rg=<pfad>`); von Hand
 bearbeitet wird die Datei nicht. `doctor` meldet
 unter `tool-paths`, ob alle Pfade noch stimmen.
 **Aufgaben-Tracker anbinden - optional.** Der Wochenrückblick (`tools/wikitool review`, Skill
 `gtd-weekly-review`) gleicht die Projektseiten unter `kb/gtd/` gegen einen Aufgaben-Tracker ab. Welcher
 das ist, steht in `.wikitool-tasks.json` im Repo-Root - der dritten Datei dieser Art neben
 `.wikitool-telemetry.json` und `.wikitool-remotes.json`: pro Checkout, ohne `.template`, und
 **gitignored, sobald ein Token darin liegt**. Fehlt sie, ist schlicht kein Tracker konfiguriert;
 das ist ein gültiger Endzustand, kein Fehler. Kaputt ist sie dagegen ein `FAIL` - eine
 unlesbare Konfiguration darf nicht als „kein Tracker" durchgehen.
 ```json
 {
  "schema": 1,
  "provider": "superproductivity",
  "thresholds": {
    "stalled_waiting_days": 14,
    "unpaged_project_weeks": 3,
    "someday_stale_months": 5
  },

    "access": "api",
    "api_base_url": "http://127.0.0.1:3876",

  }
 }
 ```
 ```json
  "superproductivity": {
    "access": "snapshot",
    "backups_dir": "~/.config/superProductivity/backups"
  }
 ```
 `provider` wählt den Adapter - ausgeliefert werden `superproductivity` und `caldav`. Der
 `thresholds`-Block trägt die drei Schwellwerte des Rückblicks (Konfiguration, nicht Schema): ab
 wann ein Waiting-For überfällig ist, ab welchem Alter ein Tracker-Projekt ohne `kb/`-Seite
 gemeldet wird, und ab wann ein Someday-Eintrag als verstaubt gilt. Ein Wert, den der Provider
 gar nicht liefern kann - ein Waiting-Posten ohne Wiedervorlagedatum, ein Tracker-Projekt ohne
 bestimmbares Anlagedatum - wird vom Rückblick nicht still übersprungen, sondern als eigene
 Fundstelle gemeldet (`waiting_no_follow_up`/`project_age_unknown`).
 Der gleichnamige Provider-Block trägt dessen Verbindungsangaben, und bei Super Productivity
 entscheidet `access` **verpflichtend und ohne Rückfall**, welcher von zwei sich ausschließenden
 Wegen das ist: eine headless bediente Instanz setzt `access: "snapshot"` und liest
 ausschließlich den jüngsten Backup-Schnappschuss unter `backups_dir` (läuft auch ohne laufende
 App, aber rein lesend - der Tracker ist von dort aus nicht schreibbar); eine Desktop-Instanz
 setzt `access: "api"` und spricht ausschließlich die lokale REST-API an, die nur antwortet,
 solange die App läuft, dafür aber auch den aktuellen Zustand liefert und den Schreibpfad trägt.
 Der Block nennt nur die Felder seines eigenen Wegs - ein `backups_dir` neben `access: "api"` oder
 ein `api_token` neben `access: "snapshot"` wird beim Lesen der Konfiguration abgelehnt, nicht
 ignoriert. `api_token` ist bei `access: "api"` Pflicht, da jeder Endpunkt außer `GET /health`
 `Authorization: Bearer <token>` verlangt.
 `tools/wikitool new project` legt einen gleichnamigen Tracker-Eintrag nur auf einer
 `access: "api"`-Instanz an (und auch dort nicht automatisch - siehe die Kommandotabelle). Auf
 einer `access: "snapshot"`-Instanz verweigert das Kommando vollständig, exit 1: der Tracker ist
 von dort aus nur lesbar. Dasselbe gilt für `tools/wikitool task new`, den zweiten Schreibweg:
 es legt einen einzelnen Posten im Tracker an - ohne `kb/`-Seite - und existiert ebenfalls nur
 auf einer `access: "api"`-Instanz. `tools/wikitool task close --id` ist der dritte und letzte
 Schreibweg - er markiert einen Posten erledigt, löscht ihn nie - und verweigert auf
 `access: "snapshot"` auf dieselbe Weise. `tools/wikitool task list --project` ist rein lesend
 und beantwortet daher auf beiden Zugriffsarten.
 **`caldav`** ist der standardbasierte zweite Adapter (RFC 4791/5545), gegen Nextcloud Tasks
 verifiziert, mit iOS *Erinnerungen* als mobilem Client - gebaut nach dem Zuschnitt: auf dem
 Telefon wird abgehakt, gepflegt wird am Schreibtisch. Anders als bei Super Productivity gibt es
 nur einen Zugriffsweg - CalDAV ist immer ein Netzwerkzugriff, kein `access`-Feld nötig:
 ```json
  "caldav": {
    "url": "https://<host>/remote.php/dav/calendars/<user>/",
    "username": "<login>",
    "app_password": "<Nextcloud-App-Passwort>",
    "inbox_list": "Inbox",
    "someday_list": "Someday",
    "exclude_lists": ["<vorhandene Liste, die kein Projekt ist>"]
  }
 ```
 `url` zeigt auf das CalDAV-Calendar-Home-Set des Kontos; sie darf ein Alias sein (Nextcloud
 akzeptiert dort einen Kurznamen), da jede spätere Adresse ausschließlich aus den vom Server
 gelieferten `href`s stammt, nie aus dieser URL und einem Namen zusammengesetzt wird. `username`
 ist der Login-Name, der von der Benutzer-ID in der URL abweichen kann - ein
 Nextcloud-App-Passwort wird empfohlen, nicht das Kontopasswort. `inbox_list`/`someday_list`
 nennen die beiden festen Listen (je genau eine pro Instanz); `exclude_lists` nimmt vorhandene
 reine Aufgabenlisten heraus, die keine Projekte sind - eine Liste mit `VEVENT`-Anteil zählt
 ohnehin nie als Projekt.
 Ein Projekt ist dort eine Liste, deren unterstützte Komponente ausschließlich `VTODO` ist; `tools/wikitool
 new project` legt sie automatisch per `MKCALENDAR` an - anders als bei Super Productivity ohne
 Rückfrage, weil CalDAV einen echten Anlage-Befehl für Listen kennt. Die Eindeutigkeitsprüfung
 läuft gegen **jede** Liste im Konto, auch gegen ausgeschlossene, Inbox, Someday und gemischte
 Kalender - kollidiert ein neuer Name mit einer davon, wird nichts angelegt und die Kollision
 genannt; die vorhandene Liste in Nextcloud umzubenennen bleibt Handarbeit. `tools/wikitool task
 new`/`task close` funktionieren auf einer `caldav`-Instanz uneingeschränkt - es gibt keinen
 reinen Lesemodus wie `access: "snapshot"`. Beim Abhaken ändert `task close` ausschließlich
 `STATUS`, `COMPLETED`, `PERCENT-COMPLETE`, `LAST-MODIFIED` und `DTSTAMP` an der bestehenden
 `.ics`-Ressource; jede andere Eigenschaft - auch eine unbekannte `X-`-Eigenschaft oder ein Alarm
 - bleibt unverändert erhalten, und eine seit dem Lesen veränderte Ressource (ETag-Konflikt)
 schreibt nichts und bricht mit exit 1 ab. Gelöscht wird nie etwas.
 Listen abgeschlossener Projekte bleiben nach dem Archivieren bestehen - der Adapter löscht nie
 eine Liste; das übernimmt der Betreiber von Hand in Nextcloud, sobald gewünscht.

 A directory under `kb/` is a **collection** exactly when it holds a `COLLECTION.md`; a
 subdirectory inside one is an **area** that inherits it, and that is as deep as a page goes -
 nothing nests below an area, because the generated catalog reads exactly two path segments
 under `kb/` and would fold a deeper page into the area silently (`kb/CONTRACT.md` § Collections
 has the rule; `wikitool lint` reports a violation as a hard error).
 Which areas a collection has is not chosen per page: a type-spec's `layout:` maps its subtype
 field onto directories, and `wikitool new` writes the page straight into the one its subtype
 names. That is also what makes the catalog's shard threshold do anything - `index rebuild`
 splits **per area**, so a collection with no areas keeps one table however large it grows.
 `wikitool lint` reports such a collection once it is past the threshold, as a recommendation
 rather than an error, together with the split its subtype field would produce; it stays quiet
 when the split would not actually help. `kb/comparisons/` is the worked example of a collection
 that stays flat - it has no subtype field for a `layout:` to key on at all. A *lopsided* subtype
 field is a different case and is fixed rather than left flat: `kb/sources/` looked lopsided only
 because `source_type` had a schema `default:` that the compiler applied whenever nobody chose a
 value, and once that was removed and the pages reclassified it split into six real areas.
 `COLLECTION.md` never appears outside `kb/` - the other layers carry a `CONTRACT.md` or a root
 type-spec instead. A stage may carry both a `README.md` and a `CONTRACT.md`: they have different
 readers. The README is for humans working *on* that layer, the contract is what binds an agent
 working *with* it.
 ## How to Use
 ### Adding Knowledge (Ingest)
 1. Drop a file into `incoming/` - directly, no classification to make. Files that belong
   together go into one folder there instead: a folder is one source, accepted whole with
   its structure kept. Everything past that (the destination in `raw/`, which is a `YYYY/MM`
   shard of the day it was accepted, and whether several files of one source get bundled)
   is computed by `tools/wikitool raw accept`, never chosen by hand
 2. Tell the LLM: `Ingest incoming/my-article.md` - or just `Ingest`, which takes the oldest
   entry waiting in `incoming/` (`tools/wikitool raw pending` lists them). It will ask you
   two things before promoting: how faithful the capture is (`fidelity`) and what the material may claim
   about its subject (`authority`). Both are recorded once and never guessed - they are
   knowable now and unrecoverable later
 3. The LLM will:
   - Promote it into `raw/` with `raw accept`
   - Read and summarize the source
   - Create a source page in `kb/sources/`
   - Create or update relevant entity pages
   - Create or update relevant concept pages
   - Add cross-references between everything
   - Rebuild the catalog and append to `kb/log.md`
 A document can also arrive from outside, through the MCP server's optional `submit` tool
 (see [INSTALL-MCP.md](INSTALL-MCP.md)): it lands in `mcp-upload/`, not `incoming/`, and a human
 reviews and promotes it with `wikitool upload accept` before step 1 above applies - see
 [instructions/ingest-queue.md](instructions/ingest-queue.md).
 A web page needs no download of your own: tell the LLM `Ingest https://example.org/post`, and
 `tools/wikitool raw fetch` puts the page into `incoming/` - the HTML exactly as received, plus a
 text derived from it with a header recording where and when it was fetched. Behind a paywall or a
 login, save the page from your browser into `incoming/` (HTML only) instead; the LLM derives the
 same text from that file with `raw fetch --html`. See [raw/CONTRACT.md](raw/CONTRACT.md).
 Documentation that lives in a git repository is captured, not copied: `tools/wikitool raw capture
 <repo-url> --ref main --path 'docs/**/*.md' --name <bundle> ...` writes the matching files, byte
 for byte, into `incoming/<bundle>/` together with a `_capture.json` manifest naming the repository,
 the ref rule and the commit. Later, `tools/wikitool raw status` tells you which captured bundles
 have fallen behind their repository, file by file; `raw capture --update` and `raw accept
 --replaces-bundle` take the new edition in as a whole. You need not run any of that yourself:
 tell the LLM `Update the captured repositories`, and it checks them, takes one changed bundle per
 run into the wiki and says how many are still behind. Git uses your own keys and credential
 helpers - nothing is stored in the repository.
 The same repositories can get something back: the wiki's guidelines, as one generated
 `GUIDELINES.md` in their root. Which pages count as guidelines is your decision, written down in
 `kb/CONVENTIONS.md` (§ Guidelines for other repositories); `tools/wikitool export guidelines
 --tag guideline` prints the file as it would be written. A repository takes part by carrying a
 `GUIDELINES.md` whose first line is `<!-- wikitool:export kind=guidelines -->` - commit that one
 line there, and point the repository's own `AGENTS.md` at the file (Claude Code:
 `@GUIDELINES.md`). A hand-written `GUIDELINES.md` is never touched. Then tell the LLM
 `Roll out the guidelines to the captured repositories`: it runs `export guidelines --push`, which
 stops before pushing anything (the **Guideline Push Gate**) and shows you, per repository, what
 would change - the LLM puts every diff in front of you, and only your approval pushes one commit
 per repository, changing only that file, straight onto its branch.
 ### Querying Knowledge
 Ask questions naturally:
 - "What projects use MQTT?"
 - "Show me the architecture of HA Integration"
 - "Compare gdeploy and plugnburn-edl"
 - "What decisions were made about E3DC integration?"
 The LLM will search the wiki, synthesize an answer, and cite sources.
 ### Maintaining Knowledge (Lint)
 Periodically run: `Lint the wiki`
 The LLM will:
 - Run `tools/wikitool lint` for a deterministic structural + provenance scan
  (broken wikilinks, orphan pages, index drift, schema gaps, uncovered raw
  files, citation/frontmatter drift)
 - Check for contradictions (semantic judgment)
 - Find stale claims
 - Identify orphan pages and missing cross-references
 - Rebuild `kb/index.md` and `kb/provenance.md`, append to `kb/log.md`
 - Generate a report
 See the [Maintenance](#maintenance) section below for the full schedule and
 command reference.
 ### Reviewing Commitments (Weekly Review)
 Say: `Run the weekly review`
 Knowledge and commitments keep different clocks, so they live in different
 places. A page under `kb/gtd/` is one committed initiative's durable memory -
 its goal, who is involved, where it stands, why it is worth doing - and it never
 summarizes the task list. The open items live in a task tracker that owns them,
 configured per checkout in `.wikitool-tasks.json` (see
 [INSTALL.md](INSTALL.md) § Konfiguration; no tracker configured is a valid
 state, and the pages work without one).
 Nothing syncs between the two. `tools/wikitool review` joins them at read time
 over the project name and prints what needs a decision: initiatives with no next
 action, waiting-fors past their follow-up date, tracker projects with no page,
 active pages with no open loop, someday items gone stale. It stores nothing -
 not even a report file. The `gtd-weekly-review` skill then walks the findings with
 you and turns each one into a decision; `tools/wikitool new project` is what
 gives a new initiative its page and its tracker project under one name, and
 `tools/wikitool task new` files a single open item into the tracker - the
 commitment half of a source that carries both something to know and something
 to do, with no page of its own. `tools/wikitool task list` reads a project's
 open items back with their tracker id, and `tools/wikitool task close --id`
 marks one done - never deletes it - closing the loop the same source-driven
 way `task new` opened it, or the way the weekly review proposes it for a
 `waiting_overdue`/`someday_stale` finding once you confirm.
 Why the split runs this way, rather than syncing the two:
 [docs/explanation/knowledge-and-commitment.md](docs/explanation/knowledge-and-commitment.md).
 ## Page Types
 Every page type the stack ships - entity, concept, source, comparison, project - with its
 subtypes, the directory each is written to and its required fields, is listed in
 [docs/reference/page-types.md](docs/reference/page-types.md), generated from the type-specs. An
 instance adopts those type-specs and may change them, so for the types *this* instance has, ask
 the tool:
 ```bash
 tools/wikitool types list
 tools/wikitool types describe entity
 ```
 ## Workflows
 ### For You (Human)
 1. **Curate sources** - Drop files you want processed into `incoming/` - directly, or one folder
   per source
 2. **Ask questions** - Query the wiki naturally
 3. **Review changes** - Check `kb/log.md` and `kb/index.md`
 4. **Direct the LLM** - Guide it on what to emphasize or investigate
 5. **Browse in Obsidian** - Open the wiki directory in Obsidian for visualization
 ### For the LLM
 `AGENTS.md` is the cross-cutting schema/policy; the step-by-step procedures
 themselves live as independently-discoverable skills under `.agents/skills/`
 (mirrored to `.claude/skills/` for Claude Code via `tools/wikitool instructions sync`).
 Which skills ship, what each does and which requests start it:
 [docs/reference/skills.md](docs/reference/skills.md), generated from the skills themselves.
 Each skill's underlying mechanical work (frontmatter, cross-references, index/log,
 decay math, publishing) is delegated to `tools/wikitool` - never hand-edited.

 ## Tips
 ### Naming
 - Use human-readable titles with spaces for files: `Hybrid Search.md`, not kebab-case
 - Use singular for entities: `HA Integration.md` (not `HA Integrations.md`)
 - Use wikilinks matching the file name exactly: `[[Entity Name]]`
 - A title is a file name, so it has to work on Windows and macOS as well: no `< > : " / \ | ? *`,
  no reserved names such as `CON` or `Index`, no trailing dot, and no second page whose title
  differs only by case. `wikitool new` and `wikitool rename` refuse such titles, `wikitool lint`
  reports existing ones, and `kb/CONTRACT.md` § Titles are identifiers has the full rule
 - A file's whole path below the instance root stays at 160 characters or fewer, so a Windows
  checkout works without long paths: `new`, `rename`, `move` and `raw accept` refuse a longer
  one, and `lint` reports existing ones as Long Paths (advisory; `wikitool rename` is the fix)
 - **Titles follow the subject's own established name, not the wiki's language.** `Act Runner` and
  `GitOps Ownership Model` keep theirs. A title is the only identifier a page has - it also lives
  in every wikilink and citation id pointing at it - so translating one is a rename, never an
  edit: `tools/wikitool rename`, per `instructions/page-lifecycle.md`
 ### Organization
 - Start with a few broad categories, refine as needed
 - Don't over-organize early - let structure emerge
 - Use tags for cross-cutting concerns
 ### Quality
 - The LLM will maintain quality standards from `AGENTS.md`
 - Review changes periodically
 - Flag issues to the LLM
 ## Maintenance
 The wiki is kept healthy by deterministic `tools/wikitool` commands, run by the
 LLM (via the skills above). The schedule - which task runs how often, and with
 which command - lives in [`tools/CONTRACT.md`](tools/CONTRACT.md#maintenance-schedule),
 next to the command reference it depends on, so the two cannot drift apart.
 The notes below explain the three parts of it that need more than one line.
 **Provenance.** Every fact should trace back to a raw file. Source pages
 declare their backing `raw_files:`; entity/concept pages declare `provenance:`
 (`sourced`/`general`/`mixed`) and cite specific claims inline with a
 `[^cite-id]` footnote (`tools/wikitool cite add` mints the id and definition;
 placing the marker in the prose is still manual). `tools/wikitool sources
 coverage` finds raw files with no source page yet, `sources trace` answers
 "where did this come from?" in either direction, and `sources rebuild-index`
 regenerates the reverse index at `kb/provenance.md`. `lint` cross-checks that
 citations and frontmatter `sources:` lists agree, and hard-errors on any
 leftover pre-migration `^[[...]]` marker.
 **Git automation.** `tools/wikitool publish` stages everything, commits with
 an auto-generated changed-file list, and pushes to `origin/main` in one step -
 never run raw `git commit`/`git push` for wiki changes. Without `--no-push` it stops with
 exit 1 before committing when the remote is not configured or cannot be reached; a local-only
 instance passes `--no-push` on every call. Publishes touching
 ≥10 files exit **42** (the **Mass-Update Gate**) - a distinct "a human must see
 this" code, not an error - printing the full file list and the
 `--confirm <token>` line that publishes it. The token digests that file list,
 so a clearance never carries to a changeset the user did not see.
 **Guideline push.** `tools/wikitool export guidelines --push` exits **42** the same way (the
 **Guideline Push Gate**) before it writes `GUIDELINES.md` into any captured repository, printing
 every target's status and diff and the `--confirm <token>` line. The token digests each target's
 branch tip and the file, so a moved branch or an edited guideline asks again.
 **Iteration/cost limits.** Every `tools/wikitool` call is checked against a
 hard, code-enforced per-session budget before it runs (default: 60 calls, or
 3 identical calls in a row) - not just a prompt instruction to stop. Past the
 limit, the command refuses to run until a human approves continuing with
 `--override-budget`. `budget status` stays readable at all times; `budget
 reset` clears the counter and therefore needs `--yes` of its own. See
 AGENTS.md's "Gates" section.
 ## Telemetry and evaluation
 In this checkout, every `wikitool` call appends an event to
 `reports/telemetry/<session>/trace.jsonl`, and the hook files under `.github/hooks/` and
 `.vibe/` add what the agent did between those calls. Nothing leaves the machine: `reports/` is
 gitignored and no exporter is configured.
 **A distributed instance records nothing unless it asks to.** The default follows the
 installation form - on for a git clone of this repo, where the traces are the stack's own
 measuring instrument, off for an instance installed from a release, where nobody ordered
 telemetry. Two
 quantity caps apply either way: 5 MiB per session trace, and 250 session directories.
 `wikitool doctor` reports which state a checkout is in and why; EVALS.md § "Whether it runs at
 all" has the precedence rules and the opt-in file.
 That record is what makes it possible to ask how a session *worked*, not just what it left
 behind:
 ```bash
 tools/wikitool eval sessions              # which sessions have a trace
 tools/wikitool eval score                 # score this session
 ```
 A score has two halves - the structural state of the tree, from lint's own checks, and
 trajectory rules over the trace, which catch things no unit test can: a refused call repeated
 unchanged, a gate flag passed without that gate having refused anything.
 [`EVALS.md`](EVALS.md) is the full picture: the event contract, what each agent harness can and
 cannot report, what is redacted, and why there is deliberately no LLM judge yet.
 ## Tools Integration
 ### wikitool (deterministic CLI)
 Mechanical wiki operations - never hand-edited by the LLM - are handled by
 `tools/wikitool`: scaffolding pages, renaming and deleting them, cross-references,
 index/log/provenance regeneration, structural linting, and publishing.
 Every command carries one data record - synopsis, properties, copyable examples,
 each exit cause with what to do about it, prohibitions, and notes on its
 behaviour - kept next to its code. `tools/wikitool <command> -h` prints it,
 `tools/wikitool -h` prints a one-line index of all of them, a command that fails with
 exit 1 prints the record's reactions on stderr right under its `ERROR` line, and
 [`tools/CONTRACT.md`](tools/CONTRACT.md) holds a generated copy together with the
 maintenance schedule; `tools/wikitool docs verify` checks that copy and every
 command's flags against the CLI in both directions. [`tools/README.md`](tools/README.md)
 is the other half: how the CLI is built and how to add a command. `AGENTS.md`
 holds the invariants that say when each command is mandatory.
 ```bash
 tools/wikitool -h
 tools/wikitool <command> -h
 ```
 <!-- dist:strip-start -->
 Dev-instance-only: extending `tools/wikitool`, the type schema, or the instruction/skill layer
 itself is a separate session type with its own rules, covered by the `stack-dev`,
 `stack-build` and `stack-close` skills nested under `instructions/dev/` (never present in a
 distributed instance - `tools/CONTRACT.md` explains why).
 <!-- dist:strip-end -->
 ### MCP read server (optional)
 The terminal is not the only way in. `tools/chemenu/mcp/` serves the same wiki read-only over
 MCP - `search`, `types`, `describe_type`, `lint` and `status` - so a consumer that is not a
 shell on this machine can ask the same questions and get the same answers. Literally the same:
 the CLI and the server are two adapters over one core, and a golden test holds their output
 together rather than trusting that it agrees.
 There is no tool that writes, and not because one is filtered out of a list: the server imports
 nothing under `chemenu/commands/`, so `new`, `publish` and the rest are unreachable from it.
 Every answer carries the commit it was computed from, so a checkout that has fallen behind
 produces a visibly stale answer instead of a confident wrong one.
 ```bash
 tools/.venv/bin/pip install -r tools/requirements-mcp.txt
 WIKI_TRACE=0 tools/.venv/bin/python -m chemenu.mcp                # stdio
 WIKI_TRACE=0 tools/.venv/bin/python -m chemenu.mcp \
    --transport streamable-http --host 0.0.0.0 --port 8000        # deployed
 ```
 The dependency is deliberately not in `requirements.txt`: an instance that only uses the CLI
 should not have to install a web stack to do it.
 Installing it, wiring a client to it, and putting authentication in front of it:
 [`INSTALL-MCP.md`](INSTALL-MCP.md), for humans. The agent-side operating procedure - keeping the
 checkout current, and what a stale answer looks like - is
 [`instructions/mcp-read-server.md`](instructions/mcp-read-server.md).
 ### Obsidian
 Open this directory in Obsidian for:
 - Graph view of connections
 - Easy navigation with wikilinks
 - Plugins: Dataview, Marp, etc.
 ### Git
 This is a git repo. Use it for:
 - Version history
 - Branching for experiments
 - Collaboration
 ### Search
 `tools/wikitool search "<text>"` searches `kb/` directly - by text, or by frontmatter with
 `--field entity_type=system` or `--field '!sources'`. It is read-only and is the one
 command not counted against the session budget, because looking before acting is the habit
 worth encouraging.
 For browsing rather than searching, `kb/index.md` is the catalog map and each collection
 carries its own `INDEX.md`.
 ## IT-Specific Features
 This wiki is tailored for IT work with:
 - **Entity types** specific to software development and systems
 - **Relationship types** like `hängt ab von`, `verwendet`, `implementiert` - the vocabulary is in
  [kb/CONVENTIONS.md](kb/CONVENTIONS.md), because it is this instance's rather than the stack's
 - **Templates** per page type, and per subtype where its pages need a shape of their own - a person, a decision record (ADR)
 - **Guidelines** for documenting technical decisions
 - **Cross-reference patterns** for code and architecture
 ## Files Created Automatically
 The LLM will create and maintain:

 a red run means is in
 [instructions/dev/tracker-testing.md](../../instructions/dev/tracker-testing.md).
 ### How much of the stack the suite reaches
 Coverage is measured in CI - `pytest --cov`, config in `tools/.coveragerc`, HTML and XML
 uploaded as the `coverage-<run id>` artifact of every run.
 **Fetch that artifact from the run's own page, not from the API**: `upload-artifact@v3` writes
 through the older artifact API, and the Actions artifact REST endpoints answer `total_count: 0`
 for a run whose artifact the run page offers for download. The upload works; only the listing
 does not see it. Do not re-derive this, and do not read the empty list as a failed upload.
 It is enforced at a floor of **85%** (`fail_under` in `tools/.coveragerc`), which is what a red
 suite from this axis means: coverage actually fell, not that a wrapper was added. The floor was
 set only after the number had been watched - it was deliberately held back for exactly that, and
 the two points between 85 and the measured 87.0% are the room the taxonomy below asks for. A
 threshold at the measured number goes red on the next thin Typer wrapper, and a threshold that
 goes red for a non-reason gets lowered rather than earned.
 **Measured 2026-09-04, stack 4.7.1: 87.0% of 6498 statements across `chemenu/`, 975 tests** -
 CI run 163. The first measurement, at stack 1.8.1 on 2026-08-31, was 86.9% of 5105 statements
 over 730 tests (CI run 87). Both are what CI reported, never a local run: the local number
 preceding a release measures a tree that is one commit short of the published one.
 The pair says more than either number does. Between them the measured code grew by a quarter
 and the suite by a third, and the quota moved by a tenth of a point - which is the observation a
 threshold was waiting for, rather than the total itself. Reproduce either with
 `cd tools && .venv/bin/python -m pytest -q --cov` (needs `pytest-cov`, which is CI-only and
 deliberately absent from `tools/requirements.txt` - an instance runs the wiki, it does not
 measure this suite).
 The total stays the least interesting number here. What the report is for is *which* modules sit
 low, and three kinds have to be told apart before any of it turns into work:
 - **Thin Typer wrappers**, where the logic lives beside them and is tested there:
  `eval_cmd.py` (36%), `types_cmd.py` (40%), `search.py` (49%), `cli.py` (54%),
  `links_cmd.py` (61%). Low coverage on a wrapper is evidence of a good cut, not of a missing
  test - `search.py`'s uncovered block is its command body alone, while the backends under
  `chemenu/search/` that do the work sit between 91% and 98%.
 - **Code that reaches the network or the filesystem's outside**, where the interesting half is
  already injectable and tested through the seam: `version.py`'s `fetch_latest()` takes a
  `fetcher` parameter for exactly that. The real `urllib` lines are exercised too, but only
  against a local `http.server` in `test_dist_upgrade.py` (`dist upgrade --latest`) - never
  against a real feed, which stays uncovered on purpose.
 - **Genuine gaps**, where uncovered lines are logic nobody exercises: `provenance_cmd.py`
  (44%), `migrate_cmd.py` (65%), `type_resolver.py` (79%). This is the list worth reading, and
  the only one of the three that has not moved while everything around it did:
  `provenance_cmd.py` sits where it sat, and `migrate_cmd.py` fell from 71% because it grew and
  its new lines arrived untested. The floor freezes this; it does not close it. Closing it is

 ## A wiki that is compiled, not searched
 Chemenu is a pattern for a personal knowledge base maintained by an LLM. A plain retrieval setup goes
 back to the raw documents for every question. Here, the LLM **builds and maintains a persistent
 wiki** incrementally instead, and the wiki compounds over time. Knowledge is compiled once and kept
 current, not re-derived for every question.
 That one decision shapes everything else. Raw material is kept unchanged as evidence, and compiled
 pages cite it. Every mechanical step of the compilation - frontmatter, cross-references, the catalog,
 the log, publishing - is done by a deterministic tool, never by hand, so it comes out the same way
 every time.
 ## The language of the pages
 Source material in `raw/` is never touched and stays in whatever language it arrived in. The
 compiled pages under `kb/` are written in the instance's own language. The origin repository's demo
 corpus, for instance, is German. What stays in its original form inside a page is everything that
 is an *identifier* rather than prose: page titles, section headings the tool owns, wikilink targets,
 citation ids, schema enum values, tags, commands, paths and code. So `GitOps Ownership Model` and a
 German section heading sit in the same page without contradiction.
 Which lines count as identifiers is the stack's rule,
 [kb/CONTRACT.md § Language and identifiers](../../kb/CONTRACT.md#language-and-identifiers).
 *Which language* the prose is in, and what the tool-owned headings are called, is the instance's own
 `kb/CONVENTIONS.md`. That is a per-instance decision, not a property of the pattern, so it lives in a
 file the instance owns rather than in one the stack ships. A new instance picks its language when it
 fills in `kb/CONVENTIONS.md`, before the first ingest. Why the control plane stays English
 regardless: [language-boundaries.md](language-boundaries.md).

 The collections and areas under `kb/` shown here are the origin repository's. An instance's own come
 from its type-specs, as described below.
 <!-- dist:strip-start -->
 Only in the origin repository (`tools/CONTRACT.md` explains how an instance comes to lack them):
 ```
 ├── docs/dev/           # Human-readable: development environment and release workflow
 └── commonplace/        # Vendored, read-only knowledge base
 ```
 <!-- dist:strip-end -->
 ## Collections and areas
 A directory under `kb/` is a **collection** exactly when it holds a `COLLECTION.md`. A subdirectory
 inside one is an **area**, which inherits it, and that is as deep as a page goes. Nothing nests
 below an area, because the generated catalog reads exactly two path segments under `kb/`, and it
 would silently fold a deeper page into the area. `kb/CONTRACT.md` § Collections has the rule, and
 `wikitool lint` reports a violation as a hard error.
 Which areas a collection has is not chosen page by page. A type-spec's `layout:` maps its subtype
 field onto directories, and `wikitool new` writes each page straight into the one its subtype names.
 That is also what gives the catalog's shard threshold any effect: `index rebuild` splits **per
 area**, so a collection with no areas keeps one table however large it grows. Once such a collection
 is past the threshold, `wikitool lint` reports it as a recommendation rather than an error, together
 with the split its subtype field would produce. It stays quiet when the split would not actually
 help.
 `kb/comparisons/` is the worked example of a collection that stays flat: it has no subtype field for
 a `layout:` to key on at all. A *lopsided* subtype field is a different case, and it gets fixed
 rather than left flat. `kb/sources/` looked lopsided only because `source_type` had a schema
 `default:`, which the compiler applied whenever nobody chose a value. Once the default was removed
 and the pages reclassified, it split into six real areas.
 Every page type the stack ships, with its subtypes, its directories and its required fields, is in
 [page-types.md](../reference/page-types.md). An instance adopts those type-specs and may change
 them; `tools/wikitool types list` and `tools/wikitool types describe <type>` show what one instance
 has.
 ## Contracts and READMEs
 `COLLECTION.md` never appears outside `kb/`. The other layers carry a `CONTRACT.md` or a root
 type-spec instead. A stage may carry both a `README.md` and a `CONTRACT.md`, because they have
 different readers: the README is for humans working *on* that layer, and the contract binds an agent
 working *with* it. `AGENTS.md` § File naming says which file is for which reader, and
 `wikitool docs verify` checks it.
 ## Who does what
 **You** curate sources by dropping them into `incoming/`, ask questions, review what changed in
 `kb/log.md` and `kb/index.md`, and steer the agent on what to emphasise or look into. The
 [how-to guides](../how-to/README.md) cover each of these.
 **The agent** follows `AGENTS.md`, the cross-cutting schema and policy, and runs the step-by-step
 procedures as skills. They are published into `.agents/skills/`, and mirrored into
 `.claude/skills/` for Claude Code, by `tools/wikitool instructions sync`. Which skills ship, what
 each does and which requests start it: [skills.md](../reference/skills.md).
 **`tools/wikitool`** does every mechanical step a skill needs: scaffolding, renaming and deleting
 pages, cross-references, regenerating the catalog, log and provenance index, structural linting,
 decay math, and publishing. The agent calls it and never does that work by hand. Along the way it
 maintains:
 - `kb/index.md`, the catalog, always current;
 - `kb/log.md`, the complete audit trail;
 - `kb/provenance.md`, the reverse index from raw files to pages;
 - pages of every type, each in the directory its type-spec names;
 - lint reports, session traces and eval scores in `reports/`, which is gitignored.
 ## The compiler: `tools/wikitool`
 Every command carries one data record kept next to its code: synopsis, properties, copyable
 examples, each exit cause with what to do about it, prohibitions, and notes on its behaviour. The
 same record is rendered four ways:
 - `tools/wikitool <command> -h` prints it, and `tools/wikitool -h` prints a one-line index of every
  command;
 - a command that fails with exit 1 prints the record's reactions on stderr, right under its `ERROR`
  line;
 - [tools/CONTRACT.md](../../tools/CONTRACT.md) holds a generated copy for agents, together with the
  maintenance schedule;
 - [the command reference](../reference/commands/README.md) is a generated copy for humans.
 `tools/wikitool docs verify` checks the copies, and every command's flags, against the CLI in both
 directions. [tools/README.md](../../tools/README.md) is the other half: how the CLI is built and how
 to add a command. `AGENTS.md` holds the invariants that say when each command is mandatory.
 The wiki is also a git repository, and `tools/wikitool publish` is the one way its changes are
 committed and pushed. That gives every change a version history, and the gates in front of
 `publish` decide what needs a human to look first
 ([why-gates-are-code.md](why-gates-are-code.md)).
 <!-- dist:strip-start -->
 Extending `tools/wikitool`, the type schema or the instruction layer itself is a separate kind of
 session, with rules of its own: the `stack-dev`, `stack-build` and `stack-close` skills under
 `instructions/dev/`, which only the origin repository has.
 <!-- dist:strip-end -->
 ## The MCP read server
 The terminal is not the only way in. `tools/chemenu/mcp/` serves the same wiki read-only over MCP -
 `search`, `types`, `describe_type`, `lint` and `status` - so a consumer that is not a shell on this
 machine can ask the same questions and get the same answers. Literally the same: the CLI and the
 server are two adapters over one core, and a golden test holds their output together rather than
 trusting that it agrees.
 There is no tool that writes to `kb/`, and not because one is filtered out of a list. The server
 imports nothing under `chemenu/commands/`, so `new`, `publish` and the rest cannot be reached from
 it. Every answer carries the commit it was computed from, so a checkout that has fallen behind gives
 a visibly stale answer instead of a confident wrong one. The server's dependency is deliberately
 not in `requirements.txt`: an instance that only uses the CLI should not have to install a web stack
 for it.
 Setting it up: [set-up-the-mcp-server.md](../how-to/set-up-the-mcp-server.md).
 ## Built for IT work
 The shipped defaults are tailored to IT work:
 - **entity types** for software development and systems - codebases, systems, tools, technologies;
 - **relationship labels** such as "depends on", "uses" and "implements". The vocabulary is in the
  instance's `kb/CONVENTIONS.md`, because it belongs to the instance rather than the stack;
 - **templates** per page type, and per subtype where its pages need a shape of their own, such as a
  person or a decision record (ADR);
 - **guidelines** for documenting technical decisions, which can be exported back into the
  repositories they are about ([export-guidelines.md](../how-to/export-guidelines.md));
 - **cross-reference patterns** for code and architecture.

 ## Why, beyond the unit tests
 The test suite that ships with the origin repository checks the **compiler**: given this input, does
 `wikitool` produce that output? It says nothing about the two things that actually go wrong in
 practice: whether the *agent* followed the contracts, and whether the pages it wrote are any good.
 Those need a different kind of check. Two notes in the
 [Commonplace](https://github.com/zby/commonplace) research base, which the origin repository
 vendors, supply the theory:
 - *oracle-strength-spectrum* - correctness checks form a gradient, from hard (deterministic) to none
  (vibes). The engineering move is to *harden* oracles step by step, not to reach straight for a
  judge.
 - *evaluation-automation-is-phase-gated-by-comprehension* - comprehension, then specification,
  then generalisation. A judge built before anyone has read real failures optimises a proxy.
 That ordering is why this page describes a lot of telemetry and only a little scoring. Reading real
 traces is the first phase, and it cannot be skipped.

 - **The repo layer is the truth.** `wikitool` records its own calls, so what happened *to the wiki*
  is known even when no hook fired and no runner was involved.
 - **The runner owns session boundaries.** Not every harness reports a session start - Mistral Vibe
  has no such hook - so the process that launches the agent is what brackets a run.
 - **Hooks enrich.** They add the tool calls the repo layer cannot see: file reads, greps, shell
  commands, prompts.
 Everything joins on one session id, which every source that has to pick one resolves the same way
 (`chemenu.session`). The chain is `WIKITOOL_SESSION_ID`, then a harness's own session variable where
 one is registered (`chemenu.session.HARNESS_ENV_VARS` - Claude Code's `CLAUDE_CODE_SESSION_ID` today),
 then the parent process id. The middle step exists because the last one does not survive a harness
 that runs every tool call in its own freshly started shell. There, `os.getppid()` is a new "session"
 for every call, and neither the join nor the Iteration Budget Gate could see more than one or two
 calls of a real run. A harness only earns an entry in that chain once a live session has been
 observed setting the variable, and it has been confirmed to be the exact id the harness's own hooks
 write elsewhere in a trace. A name that merely looks plausible would mis-key a session more quietly
 than the pid fallback it replaced.
 A trace hook that only *observes* tool calls (a `PreToolUse`/`PostToolUse`-style wiring) does not by
 itself fix a harness whose events carry a different id than `wikitool`'s own emitter. The two would
 still not join. Wiring such a hook is worth doing only once this fallback chain already keys both
 sides on the same id.
 ## The trace
 One JSON object per line, appended to `reports/telemetry/<session>/trace.jsonl`. The contract is
 [tools/chemenu/telemetry/schema.py](../../tools/chemenu/telemetry/schema.py).
 | Field | Meaning |
 |---|---|
 | `v` | Schema version |
 | `ts` | ISO-8601 UTC, microsecond precision |
 | `session_id` | The join key - `chemenu.session`'s fallback chain: `WIKITOOL_SESSION_ID`, else a registered harness variable, else the parent process id |
 | `pid`, `seq` | `seq` counts **within one process**. Sort a trace by `(ts, pid, seq)` |
 | `source` | `wikitool`, `runner`, or a harness name |
 | `event` | See below |
 | `attrs` | Normalised payload - the same field names whichever harness produced it |
 | `run_key` | The `work/<runkey>/` run, when one is open |
 | `trace_id`, `span_id` | From `TRACEPARENT`, when the harness exports it |
 | `redactions` | Which secret patterns fired on this event |
 **Events.** The core - `tool.pre`, `tool.post`, `wikitool.call`, `gate.refused` - is available on
 every surface. Everything else is optional: `session.start`, `session.end`, `session.error`,
 `prompt.submitted`, `assistant.message`, `turn.end`, `tool.error`, `instructions.loaded`,
 `subagent.start`, `subagent.stop`, `compaction`, `page.written`, `publish.commit`, `budget.state` and
 `gate.cleared`.
 **The degradation rule.** No scorer may *require* an optional event. Claude Code has about thirty
 hooks and Mistral Vibe has three. A scorer built on the rich end would silently report zero on the
 poor end, which reads as "the agent did nothing" rather than "this harness cannot say". Every
 `session.start` carries a `completeness` list naming the classes its harness can emit, so a scorer
 can answer "not measurable here" instead. What each harness can report is tabled in
 [trace-and-score-sessions.md](../how-to/trace-and-score-sessions.md#what-each-harness-can-report).
 **Budget and trace are not the same set.** The Iteration Budget Gate exempts read-only retrieval,
 and the trace records it. What an agent looked at before acting is exactly what a trajectory scorer
 needs, and charging for a `search` would discourage the one habit that lowers cost.
 ## Whether it runs at all
 The default depends on how the tree got here, not on one hard-coded switch.
 [tools/chemenu/telemetry/policy.py](../../tools/chemenu/telemetry/policy.py) is the one place that
 resolves it, so `wikitool doctor`, the writer and the MCP server's start-up guard all answer the
 same question the same way:
 | Installation form | Default | Marker |
 |---|---|---|
 | Git clone of the origin repository (dev checkout) | **on** (opt-out) | No `.wikitool-release.json` |
 | An instance installed from a release, and every clone of its own repository | **off** (opt-in) | `.wikitool-release.json` present |
 The form is read off `.wikitool-release.json`, the same stamp `version check`, `dist upgrade` and
 `version notes` already use to tell a distribution from the repository it came from. Present means
 an operator never asked for telemetry. Absent means this is the dev checkout the stack ships from,
 where the traces are the stack's own measuring instrument. An instance commits the stamp with its
 first `publish`, so a clone of it on a second machine carries the stamp and defaults to off too. It
 is a consuming instance, not a measuring stand.
 **Turning it on for a distributed instance** takes a per-checkout `.wikitool-telemetry.json` at the
 root, gitignored like `.wikitool-remotes.json` and for the same reason. The consent to write
 prompts in cleartext to *this* disk belongs to the checkout, not the corpus, so a second clone must
 not inherit it silently. The setup instruction asks about it; nothing writes it automatically. Its
 shape is in the [configuration reference](../reference/configuration.md#telemetry).
 **Two independent quantity caps, both enforced fail-silent in `emit()`.** Neither is enforced in
 `write_event()`, which the test suite calls directly to exercise the format without the policy
 around it.
 - **A byte cap per session trace** (default 5 MiB), checked with one `stat` before every append.
  Once a trace is at or over the cap, further calls in that session write nothing except a single
  `telemetry.limit` event. It is elected by the same single-writer trick `session.start` uses, an
  exclusive create on a `.limit` marker file, so a trace that was cut off can be told apart from one
  whose writer simply crashed.
 - **Retention by session count** (default 250), applied once, right before a brand-new session
  directory is created. It is never applied per event, and never against the session doing the
  creating. It deletes exactly `trace.jsonl` and `.limit` from the oldest directories beyond the cap,
  and `rmdir`s a directory only once it is empty. Nothing under `reports/` is ever removed in bulk.
 The default of 250 was set above what the origin repository's own checkout had accumulated as of
 2026-09-10: 231 session directories, well under 400 KiB in total. The cap bites on future growth,
 not on the existing history.
 ## What never reaches a trace
 Prompts and assistant replies **are** recorded in cleartext, locally. A failure taxonomy cannot be
 read out of hashes, and building one is the first phase of any evaluation work. Four guards make
 that defensible, all of them in
 [tools/chemenu/telemetry/scrub.py](../../tools/chemenu/telemetry/scrub.py), so there is one place to
 audit:
 1. **Secret scrubbing.** Tokens, keys, `Authorization:` headers and `SECRET=` assignments are
   replaced with `[REDACTED:<type>]`. The scrubbing is pattern-based, so it is best effort.
 2. **A content cap.** 60 KiB per attribute, with a `[TRUNCATED n chars]` marker.
 3. **A kill switch.** `WIKI_TRACE_CONTENT=0` keeps only `<field>_length` and `<field>_sha256`. The
   digest is computed either way, so traces stay comparable.
 4. **`raw/` contents never enter a trace at all.** That text is data, not instruction
   ([AGENTS.md](../../AGENTS.md) invariant 4), and a trace gets read back later. Callers record a path
   and a digest.
 Nothing leaves the machine. `reports/` is gitignored, no exporter is configured, and where a vendor
 offers one it is off. Mistral's `enable_otel` ships prompts to Mistral Studio, so it stays `false`,
 and so does `enable_telemetry`. Claude Code's and Copilot's content gates may only be enabled
 against a collector you run yourself.
 The variables that steer all of this are in the
 [configuration reference](../reference/configuration.md#environment-variables).
 ## Evaluation levels
 Ordered by oracle strength: hard checks first, judgment last.
 | Level | Oracle | What it measures | Status |
 |---|---|---|---|
 | **L0** Pipeline | hard | A wiki the tools built themselves lints clean, and the catalog is a fixed point | **done** - in the origin repository's test suite |
 | **L1** Artifact scorecard | hard | Counters from `lint`'s own checks: hard errors and advisories, page count | **done** |
 | **L2** Trajectory | hard | Rules over the trace: was a refused call repeated, was a gate flag passed unearned, did a page change go unlogged | **done** |
 | **L3** Task evals | medium | Gold set: question → expected cited pages; ingest fixture → expected page titles. Scored by set overlap | needs the runner |
 | **L4** Rubric / judge | soft | Prose quality, cramming, tone | **out of scope** until a failure taxonomy exists |
 Evaluation results are statistical, not binary. A case runs several times and reports a pass rate
 with its variance, because sampling is not deterministic. A single failure is not a merge blocker;
 a regression against a baseline is.
 ### L0 lives in the test suite, not in a separate harness
 It runs the CLI in-process against an empty wiki. It asserts that `new` → write → `xref` →
 `index rebuild` leaves a tree `lint` calls clean, and that rebuilding the catalog again changes
 nothing on disk. That is a hard oracle over the compiler, which is what the test suite is for.
 Giving it its own runner would have duplicated the suite for nothing.
 One behaviour it pins is easy to mistake for a defect: **a scaffolded page does not lint clean**.
 `new` writes placeholder wikilinks for the author to replace. So a page that was created but not yet
 written reports broken links, and reports its `TODO`-only sections as the advisory
 *Unfilled Template Sections*. That is the scaffold saying it is unfinished.
 ## Scoring a session
 `tools/wikitool eval score` scores one session. It only reads, and it is exempt from the Iteration
 Budget Gate: reading back what a session did is not iterating on the wiki, and charging for it
 would discourage checking one's own work.
 **L1** re-runs `lint`'s checks in-process and reports their counters. It shares its definition of a
 hard error with `lint --fail-on-error` - one constant, `HARD_ERROR_KEYS` - so a run can never pass
 its score while lint refuses it.
 **L2** checks five rules. Each one restates an invariant the code cannot enforce in-process. A gate
 can refuse a call, but nothing stops an agent from calling again with the gate's own flag. That gap
 is the whole point:
 | Rule | Invariant | Severity |
 |---|---|---|
 | `refusal-not-retried` | A refused call, repeated unchanged, is the loop the gate exists to break | error |
 | `gate-not-self-opened` | `--yes`/`-y` no longer exist at all; `--override-budget` is for a human to pass after a refusal; `--force` never | error |
 | `content-change-logged` | A publish that changes `kb/` pages needs a `log append` in the same session | advisory |
 | `clearance-was-asked-for` | A `gate.cleared` token must match one some earlier `gate.refused` issued - catches an invented token, and one reused from a different changeset | error |
 | `clearance-ended-the-turn` | No `wikitool.call` between a clearance request (exit 42) and the next `prompt.submitted` - skipped, not failed, on a harness that cannot report `prompt.submitted` | error |
 New rules belong here only when a real trace shows a real failure. Checks invented from the contract
 text produce a score that improves while behaviour does not - the failure mode the phase-gate note
 describes. The first three rules were chosen because each guards a refusal an agent can talk its way
 around. The last two carry the load for the Mass-Update Gate's clearance mechanism (2026-08-28),
 which deliberately enforces very little in-process, as described below.
 A rule can report a third state besides pass and fail: **skipped**, meaning this trace cannot answer
 the question at all - for example `clearance-ended-the-turn` on a harness with no prompt hook.
 Skipped reads as neither a pass nor a violation. `scorecard.render_markdown` marks it `skip`,
 distinct from `ok`, `warn` and `FAIL`, and `score()["violations"]` never includes a skipped rule,
 whatever its severity.
 ### A worked example, and where the check moved to
 Scoring the session that shipped the telemetry layer itself used to report a failure:
 ```
 FAIL gate-not-self-opened
  call=publish --message "tools: session traces …" --yes, reason=no mass-update refusal preceded it
 ```
 That finding was true and benign at the same time. The change was 17 files, the file list was shown,
 and a human approved it. But the approval happened in conversation, and `--yes` went out on the
 first attempt, so the gate never got to refuse anything. The documented path had the refusal first,
 and the trace records tool calls, not conversations.
 Three sessions did some version of this before the mechanism changed rather than the procedure. The
 interesting part is *which* half changed. The obvious fix was built first: make the gate impossible
 to open without independent proof of a human. That meant a ticket bound to the changeset, redeemed
 only after a `prompt.submitted` event and a `wikitool approve` typed in a second terminal. It worked,
 and it was unusable. On a harness that drives `wikitool` through a shell tool, the agent cannot
 produce the turn signal, and the human is asked to leave the conversation to approve anything at all.
 A gate nobody can pass is not a safe gate, it is an abandoned one.
 So the enforcement got cheap and the *verification* got real:
 - **In-process, `publish` enforces only what it can do honestly.** Exit 42 says "a human must see
  this". `--confirm <token>` says "here is what they saw", and the token digests the file list, so it
  cannot silently cover a different one. None of that proves a human was involved, and the code says
  so in as many words.
 - **The trace answers the question the tool cannot.** `clearance-ended-the-turn` looks for a
  `wikitool.call` between an exit-42 call and the next `prompt.submitted`. That is exactly the
  "refused, then confirmed in the same breath" shape all three incidents had, and it is invisible to
  any single call. `clearance-was-asked-for` catches a token that no refusal ever issued.
 This is the loop this whole page is about, run to its conclusion: a rule that only a trace could
 check, a trace that showed it being broken three times, a mechanism rebuilt because no procedural fix
 survived - and then the check itself moved to the layer that can actually see it.
 **What this still cannot see:** an agent that receives the exit-42 output, does not relay it, and
 passes the token anyway *after* the user happens to say something unrelated. `prompt.submitted`
 proves a turn boundary, not that the output was relayed or that the reply meant yes. That gap is
 recorded rather than papered over. Closing it needs the harness to report what the agent actually
 said, which no adapter here does yet.
 That gap stopped being hypothetical within the hour. The first agent to receive the new gate - the
 one that had just written the paragraph above - answered the user with a file *count* and a pointer
 to "the output above". On that harness the user could not see the output: a command's stdout goes
 to the agent's context, not to anyone's screen. Nothing in the trace distinguishes that from a
 correct relay, and nothing ever will. The response was to fix the half that *is* fixable, the
 wording. The message now says "THE USER CANNOT SEE THIS OUTPUT", asks for the paths to be copied
 into the reply, and names the near-misses that do not count: a count, a summary, "the output above".
 An instruction that conflates printing with showing reads as already satisfied by the text existing.
 That is a general lesson about writing for agents, not a detail of this gate.

 ## The agent runner, and why it is not here yet
 Scoring reads what a session left behind. The missing half is *starting* one: a runner that launches
 a harness against a task, several times, and reports a pass rate. What it has to do is no longer
 guesswork, because the adapter work settled most of it:
 - **Give each run a copy of the repository, not a fixture directory.** `config.ROOT` is derived from
  `chemenu/config.py`'s own location, so `wikitool` cannot be aimed at another tree from outside. An
  agent case therefore needs a worktree or a clone, where the tool sits inside the tree it edits. (A
  *fixture* directory works fine in-process, which is why L0 is a test.)
 - **Give each run its own HOME:** `VIBE_HOME`, `COPILOT_HOME`, plus `WIKI_TRACE_DIR` and
  `WIKITOOL_SESSION_ID`, so that state, trust decisions and traces cannot leak between runs.
 - **Never launch Vibe without `--agent`.** Its programmatic mode falls back to `auto-approve` when no
  agent is named, and it does not ask about folder trust. The runner must refuse rather than inherit
  that default.
 - **Record a run manifest:** harness and version, model, git SHA, and hashes of `AGENTS.md`, the
  published skills and the fixture. Without it, a pass rate cannot be compared to anything.
 What is missing is not the design but the ability to check it. No provider credentials were
 configured on the machine the design was worked out on, so a live run could not be executed, let
 alone verified. Writing the runner anyway would repeat exactly the mistake the Vibe adapter avoided:
 the hook format there was wrong in the documentation, and only the installed CLI showed it. A runner
 written against an unverified mental model of three harnesses would be worse.
 Open questions: whether Claude Code has a redirectable config directory (only `--settings` is
 documented), and whether the scrubber's own patterns are enough, or a dedicated secret scanner
 belongs in the verification step.

 # Browse the wiki in Obsidian
 The wiki is a folder of Markdown files joined by `[[wikilinks]]`, so any Markdown editor can read
 it. Obsidian adds a graph of the links between pages, which makes it a good way to look around.
 ## What you prepare
 Open the instance's root directory as an Obsidian vault. Obsidian keeps its own settings in
 `.obsidian/`. That folder is personal state: it is never shipped with a release, and it has no
 effect on the wiki.
 What you get:
 - the graph view of how pages connect;
 - navigation by wikilink, the way the agent writes them;
 - plugins such as Dataview, which can query page frontmatter, or Marp for slides.
 ## Reading, not writing
 Browse and read freely. Change pages through the agent, though, not by editing them in Obsidian. A
 page carries generated frontmatter, cross-references and footnote citations that `tools/wikitool`
 keeps consistent across the whole wiki. A hand edit can quietly break them. Renaming or moving a
 file in Obsidian is the clearest case: a title is the page's only identifier, so it also appears in
 every wikilink and citation that points at the page. A rename goes through
 `tools/wikitool rename`, which updates every reference. The full procedure is
 [instructions/page-lifecycle.md](../../instructions/page-lifecycle.md).
 Generated files - `kb/index.md`, `kb/log.md`, `kb/provenance.md` and every `INDEX.md` - are
 rebuilt by the tool and never edited by hand.
 ## How pages are named
 Knowing the naming rules makes the vault easier to find your way in:
 - **Titles are human-readable names with spaces:** `Hybrid Search.md`, not kebab-case. A wikilink
  matches the file name exactly: `[[Hybrid Search]]`.
 - **Entities are singular:** `HA Integration.md`, not `HA Integrations.md`.
 - **A title follows the subject's own established name, not the wiki's language.** `Act Runner`
  and `GitOps Ownership Model` keep their names in a German wiki too. Translating a title is a
  rename, not an edit.
 - **A title works on every operating system.** It contains none of `< > : " / \ | ? *`, is not a
  reserved name such as `CON` or `Index`, does not end in a dot, and does not differ from another
  page's title by case alone. A file's whole path below the instance root stays at 160 characters
  or fewer, so a Windows checkout works without long paths. `wikitool new` and `wikitool rename`
  refuse titles that break these rules, and `wikitool lint` reports existing ones.
  [kb/CONTRACT.md](../../kb/CONTRACT.md) has the full rule.
 ## Letting the structure grow
 - Start with a few broad categories and refine as the material arrives. Don't over-organise early.
 - Use tags for concerns that cut across collections.
 - Review what the agent changed from time to time - `kb/log.md` lists every operation - and tell it
  when something is off. It keeps to the standards in `AGENTS.md` and the contracts, but you are the
  one who notices when a page misses the point.

 # Capture documentation from a git repository
 Documentation that lives in a git repository is captured, not copied by hand. A capture records the
 repository, the ref rule and the commit it came from. Later, the wiki can tell which captured
 material has fallen behind its repository, and take in the new edition as a whole.
 ## What you prepare
 Access to the repository from this machine. Git uses your own keys and credential helpers, and
 nothing is stored in the instance. Then decide three things:
 - the repository URL;
 - the ref to follow, usually a branch such as `main`;
 - which files count, as a glob, for example `docs/**/*.md`.
 ## Taking a repository in for the first time
 You can run the capture yourself, or name the three values to the agent and let it run the
 command:
 ```bash
 tools/wikitool raw capture <repo-url> --ref main --path 'docs/**/*.md' --name <bundle>
 ```
 This writes the matching files, byte for byte, into `incoming/<bundle>/`, together with a
 `_capture.json` manifest naming the repository, the ref rule and the commit. From there it is an
 ordinary source: `Ingest incoming/<bundle>` ([Ingest a source](ingest-a-source.md)), with the same
 questions and the same gate.
 ## Keeping it current
 ```bash
 tools/wikitool raw status
 ```
 This lists every captured bundle that has fallen behind its repository, file by file, marking each
 file as added, modified or deleted. It only reads.
 To bring them in, say:
 ```text
 Update the captured repositories
 ```
 The agent checks every captured bundle. It takes one changed bundle per run into the wiki, replacing
 the old edition as a whole, and tells you how many are still behind. Run it again for the next one.
 `raw capture --update` and `raw accept --replaces-bundle` are the commands underneath. What each one
 does is in the [command reference](../reference/commands/raw-material-and-uploads.md).
 ## Where the agent stops
 The same places as any ingest: the `fidelity`/`authority` questions, the discussion of what
 matters, and the Mass-Update Gate when it publishes. When one repository cannot be reached, the
 agent reports the error and carries on with the others. A failure in one never stops the run.

 # Export guidelines to captured repositories
 The repositories the wiki captures documentation from can get something back: the wiki's
 guidelines, as one generated `GUIDELINES.md` in each repository's root, which that repository's own
 agents then read.
 ## What you prepare
 - **Decide which pages count as guidelines.** That decision is yours, and it is written down in
  `kb/CONVENTIONS.md` § Guidelines for other repositories. Usually it is a tag. To see the file
  exactly as it would be written, without touching any repository:
  ```bash
  tools/wikitool export guidelines --tag guideline
  ```
 - **Opt each repository in, by hand, once.** A repository takes part only if it carries a
  `GUIDELINES.md` whose first line is exactly:
  ```markdown
  <!-- wikitool:export kind=guidelines -->
  ```
  Commit that one line there. Then point the repository's own `AGENTS.md` at the file (for Claude
  Code: `@GUIDELINES.md`). A `GUIDELINES.md` without that first line is hand-written, and the export
  never touches it.
 The repository has to be one the wiki has captured
 ([Capture documentation from a git repository](capture-repository-docs.md)). That is how the export
 knows where the repository lives. Its capture also has to follow a branch: a repository captured by
 a tag pattern is skipped, because a tag has no branch to commit onto.
 ## What you say
 ```text
 Roll out the guidelines to the captured repositories
 ```
 ## Where the agent stops
 The agent runs `export guidelines --push`, which stops before pushing anything. This is the
 **Guideline Push Gate** (exit 42). For every repository, it prints the status, the diff it would
 write and a `--confirm <token>` line. The agent puts every diff in front of you. Only your approval
 pushes, and then only one commit per repository, which changes only `GUIDELINES.md` and goes
 straight onto its branch.
 The token is a digest of each target's branch tip and of the generated file. If a branch has moved
 or a guideline was edited since you looked, the gate asks again rather than pushing something you
 did not see.

 # Ingest a source
 Turn a file, a folder or a web page into wiki pages: a source page that summarises it, and the
 entity and concept pages it touches, cross-referenced and published. The agent does the work, using
 the `wiki-ingest` skill ([skill catalogue](../reference/skills.md)). This page covers what you hand
 it and where it waits for you.
 ## What you prepare
 Put the material into `incoming/` at the root of the instance. You don't have to classify it or
 pick a directory:
 - **One file** goes in directly: `incoming/my-article.md`.
 - **Several files that belong together** go into one folder, `incoming/<name>/`. The folder is one
  source. It is accepted whole, and its structure is kept.
 - **A web page** needs no download of your own. Name the URL to the agent, and
  `tools/wikitool raw fetch` puts two files into `incoming/`: the HTML exactly as received, and a
  text derived from it with a header recording where and when it was fetched.
 - **A page behind a paywall or a login** is saved from your browser into `incoming/`, HTML only. The
  agent derives the same text from that file with `raw fetch --html`.
 Where a file ends up in `raw/` is computed by `tools/wikitool raw accept`: a `YYYY/MM` shard for the
 day it was accepted. So is whether several files of one source get bundled. You never choose either.
 `incoming/` itself is gitignored, so whatever waits there is never published by accident.
 ## What you say
 ```text
 Ingest incoming/my-article.md
 Ingest https://example.org/post
 Ingest
 ```
 A bare `Ingest` takes the oldest entry waiting in `incoming/`. `tools/wikitool raw pending` lists
 what is waiting and names the entry the next bare `Ingest` will take.
 ## Where the agent asks you
 - **Before promoting the file into `raw/`**, the agent asks how faithful the capture is
  (`fidelity`) and what the material may claim about its subject (`authority`). Both are recorded
  once and never guessed: you know the answers now, and nobody can recover them later.
  [raw/CONTRACT.md](../../raw/CONTRACT.md) defines the values.
 - **Before writing pages**, the agent presents the key takeaways and asks which points matter most
  and what to emphasise. The pages follow your answer.
 - **When it publishes**, a source that touches ten or more files stops at the Mass-Update Gate
  (exit 42). The agent shows you the file list and the `--confirm` line. Nothing is committed until
  you approve. [Exit codes and gates](../reference/exit-codes.md) lists every gate.
 ## What you get back
 A source page under `kb/sources/`, new or updated entity and concept pages, cross-references among
 them, a rebuilt catalog, an entry in `kb/log.md`, and one commit. If the source also contains
 something you have to *do*, and a task tracker is configured, the agent files it there as an open
 item. A commitment never becomes a page
 ([why](../explanation/knowledge-and-commitment.md)).
 Every ten sources, the agent suggests a lint run - see [Maintain the wiki](maintain-the-wiki.md).
 ## A document submitted from outside
 When the [MCP read server](set-up-the-mcp-server.md) has its optional `submit` tool turned on,
 documents can arrive from another machine. They land in the quarantine `mcp-upload/`, not in
 `incoming/`, and nothing else reads them there. Before an ingest can start, a human has to promote
 the submission:
 ```bash
 tools/wikitool upload list            # what is waiting
 tools/wikitool upload show <id>       # one submission's manifest: who sent it, size, checksum
 ```
 Ask the agent to review the queue, and it follows
 [instructions/ingest-queue.md](../../instructions/ingest-queue.md). Accepting a submission stops at
 the Upload Review Gate (exit 42), which shows you the manifest and the `--confirm` line. Once you
 approve, the file is in `incoming/`, and from there it is ingested like any other. Rejecting it needs
 no clearance. The file is deleted, and its checksum and your reason stay in the ledger.

 # Maintain the wiki
 Keep the wiki healthy: find broken links, orphan pages, raw files no page covers yet,
 contradictions and stale claims, then repair what can be repaired mechanically. The agent does
 this with the `wiki-lint` skill ([skill catalogue](../reference/skills.md)), and `tools/wikitool`
 does the mechanical part.
 ## What you say
 ```text
 Lint the wiki
 ```
 Do this periodically. The agent suggests it on its own every ten sources. The full schedule - which
 task runs how often, and with which command - is the
 [maintenance schedule](../../tools/CONTRACT.md#maintenance-schedule) in `tools/CONTRACT.md`, next
 to the command records it depends on.
 ## What you get back
 - A deterministic structural scan by `tools/wikitool lint`: broken wikilinks, orphan pages, catalog
  drift, schema gaps, raw files without a source page, and citations that disagree with
  frontmatter.
 - The judgment half, which no command can do: contradictions between pages, stale claims, subjects
  that deserve a page of their own, and a rule stated in two places.
 - Repairs for what is mechanical, a rebuilt catalog and provenance index, and an entry in
  `kb/log.md`.
 - A report under `reports/`, which is gitignored and never published. The agent carries the
  findings that need you into its reply.
 For a quick look without a full pass, say `Wiki status` instead. That is read-only.
 ## Provenance: where a claim came from
 Every fact should trace back to a raw file. A source page lists its raw files, and other pages
 cite specific claims inline with a footnote that points at a source page. You can ask the
 questions yourself:
 ```bash
 tools/wikitool sources coverage                  # raw files no source page covers yet
 tools/wikitool sources trace --raw raw/2026/09/x.md     # which pages rest on this file
 tools/wikitool sources trace --page "HA Integration"    # which raw files this page rests on
 ```
 `kb/provenance.md` is the generated reverse index. The commands are in the
 [provenance reference](../reference/commands/provenance.md).
 ## Where the agent stops
 - **Publishing ten or more files** stops at the Mass-Update Gate (exit 42). A lint pass that repairs
  many pages does this routinely. The agent shows you the full file list and the `--confirm` line,
  and publishes only after you approve. The token is a digest of that file list, so your approval
  never covers a changeset you did not see.
 - **The call budget.** Every `wikitool` call counts against a per-session budget: 60 calls, or 3
  identical calls in a row. Past it, calls are refused. The agent stops and summarises where it is.
  If you want it to go on, tell it so. Only then may it pass `--override-budget` on the command it
  needs. A refusal usually means the task should be split, not pushed through.
 - **No reachable remote.** Without `--no-push`, `publish` refuses with exit 1 before committing when
  the remote is not configured or cannot be reached. An instance that is meant to stay local passes
  `--no-push` on every publish.
 Every gate, and which command it belongs to: [exit codes and gates](../reference/exit-codes.md).

 # Query the wiki
 Ask the wiki a question and get an answer built from its compiled pages, with the pages and sources
 it came from. The agent answers using the `wiki-query` skill
 ([skill catalogue](../reference/skills.md)), which only reads unless you ask it to keep an answer.
 ## What you say
 Ask the way you would ask a colleague:
 ```text
 What projects use MQTT?
 Show me the architecture of HA Integration
 Compare gdeploy and plugnburn-edl
 What decisions were made about E3DC integration?
 ```
 ## What you get back
 An answer that names the wiki pages it came from and the sources behind them. Where the wiki has no
 source for a claim, the agent says so instead of filling the gap. An answer it cannot back is never
 written into the wiki either.
 If an answer is worth keeping - a comparison you will want again, a synthesis across several pages -
 the agent proposes filing it back as a page. It names the pages it would create before it creates
 any, and nothing is written unless you agree.
 ## Searching yourself
 The agent searches with the same command you can run:
 ```bash
 tools/wikitool search "<text>"
 tools/wikitool search --field entity_type=system
 tools/wikitool search --field '!sources'          # pages without a sources: list
 ```
 `search` covers all of `kb/`, by text, by frontmatter or both. Each hit carries the page's path and
 full title, so you can open it directly. It only reads, and it does not count against the
 session's call budget, because looking before acting is the habit worth encouraging. The predicate forms are in the
 [command reference](../reference/commands/finding-and-checking.md).
 For browsing rather than searching, `kb/index.md` is the catalog map, and each collection carries
 its own `INDEX.md`. All of these are generated. Read them, but never edit them. To browse the pages as
 a graph, see [Browse the wiki in Obsidian](browse-with-obsidian.md).

 # Run the weekly review
 Go through your committed initiatives once a week and decide what each one needs: a next action, a
 pause, a close. A machine prepares the list, so you don't have to reconstruct it from memory. The
 agent runs the `gtd-weekly-review` skill ([skill catalogue](../reference/skills.md)).
 ## Two places, on purpose
 Knowledge and commitments change at different speeds, so they live in different places:
 - **A page under `kb/gtd/`** is one initiative's durable memory: its goal, who is involved, where it
  stands, and why it is worth doing. It never summarises the task list.
 - **The open items** live in a task tracker, which owns them.
 Nothing syncs between the two. `tools/wikitool review` joins them when it reads, matching on the
 project name, and stores nothing - not even a report file. Why the split runs this way rather than
 syncing: [knowledge-and-commitment.md](../explanation/knowledge-and-commitment.md).
 ## What you prepare
 A task tracker, configured for this checkout in `.wikitool-tasks.json`. Super Productivity and
 CalDAV (for example Nextcloud Tasks) are supported. The file's shape, and the difference between a
 tracker the wiki can only read and one it can write to, is in the
 [configuration reference](../reference/configuration.md#task-tracker). Without a tracker, the
 review has nothing to join against. That is a valid state, though, and the pages work without one.
 ## What you say
 ```text
 Run the weekly review
 ```
 ## What you get back
 The agent runs `tools/wikitool review` and walks you through its findings, one at a time:
 - initiatives with no next action;
 - waiting-fors past their follow-up date;
 - tracker projects that have no page;
 - active pages with no open item;
 - someday items that have gone stale.
 For each finding, the agent asks what is actually true, because "this looks stalled" can mean a
 next action is missing, the initiative was paused on purpose, or it is finished. Then it proposes the
 exact change: a new item in the tracker, an item marked done, or a page's state moved to `dormant`,
 `completed` or `abandoned`. Nothing is written to the tracker until you confirm that exact call.
 What was decided goes onto the page, and the page is published.
 A quiet week is a valid result. If one of the checks could not run because the tracker did not
 answer, the agent says which check was skipped. An empty result under a skipped check means nothing.
 ## Starting something new
 Ask the agent for a new project and name it. It runs `tools/wikitool new project`, which gives the
 initiative its page under `kb/gtd/` and, where a tracker is configured, a tracker project under the
 same name. A CalDAV tracker gets that project created automatically. On Super Productivity the
 command stops with exit 42 and asks you to create the project in the app yourself. Tell the agent
 when you are done, and it continues with `--resume`. A tracker the wiki can only read refuses the
 command outright.
 A single open item with no page of its own - a commitment that came with a source, say - is filed
 with `tools/wikitool task new`. `task list` reads a project's open items back, and `task close --id`
 marks one done. Nothing deletes an item. The commands are in the
 [command reference](../reference/commands/pages.md).

 # Set up the MCP read server
 Serve an instance's wiki read-only over MCP, so that a consumer that is not a terminal on this
 machine - another agent, a chat client, a service - can ask it the same questions and get the same
 answers. This page covers what you set up around the server: the client, the authentication in
 front of it, the optional `submit` path, and how to check that it works. Installing, starting and
 syncing the server itself is

 ## What the server is, and what it is not
 The server is a second consumer of the same core as the CLI, not a second program. Both call the
 same functions, and a golden test in the origin repository holds their output together. What
 `tools/wikitool search --json` returns, the MCP tool `search` returns too, together with the commit
 the answer was computed from.
 It is not a write path into `kb/`. No tool creates, changes or publishes a page - not because a list
 is filtered, but because the server imports nothing under `tools/chemenu/commands/`. Those functions
 cannot be reached from its process. The one exception is opt-in: a sixth tool, `submit`, which
 writes only into a quarantine no other command reads. A human decides about everything that leaves
 it ([below](#optional-the-submit-path)).
 | Tool | What it answers |
 |---|---|
 | `search` | Pages in `kb/` by text, by frontmatter (`!sources`, `tags~k8s`), or both |
 | `types` | Which page types this wiki knows |
 | `describe_type` | A type's full contract: fields, required values, enums |
 | `lint` | Structural findings: broken wikilinks, orphans, catalog drift, schema gaps |
 | `status` | A snapshot: page count, distribution over collections, finding counts |
 | `submit` *(optional)* | Hands a document to the review queue - into a quarantine, never into `kb/` |
 ## What you prepare
 - A working instance ([INSTALL.md](../../INSTALL.md)), including `tools/.venv` and ripgrep.
 - For a deployment, a reverse proxy that can authenticate requests before they reach the server
  ([below](#authentication-in-front-of-it)).
 Then ask the agent:
 ```text
 Set up the MCP read server for this instance
 ```
 It installs the server's optional dependency, which is deliberately not in
 `tools/requirements.txt`: an instance that only uses the CLI should not have to install pydantic,
 starlette, uvicorn and cryptography. It also checks that tracing cannot write into the served tree.
 The server refuses to start if it could:
 ```text
 ERROR Telemetry is on and would write into the served checkout (...). Set WIKI_TRACE=0,
 or point WIKI_TRACE_DIR outside the corpus.
 ```
 That refusal is expected, not an installation fault. Telemetry is off by default in an instance
 installed from a release and on in a clone of the origin repository
 ([configuration](../reference/configuration.md#telemetry)). The server consults the same policy
 `wikitool doctor` does. Setting `WIKI_TRACE=0` explicitly, as every example here does, is correct
 either way and makes the check moot.
 ## Wiring a client to it
 Locally, over `stdio`, the client starts the server itself: one process per consumer, no network.
 The configuration follows the usual MCP client shape, with absolute paths, because the client
 inherits no working directory:
 ```json
 {
  "mcpServers": {
    "chemenu": {
      "command": "/path/to/instance/tools/.venv/bin/python",
      "args": ["-m", "chemenu.mcp"],
      "cwd": "/path/to/instance/tools",
      "env": {
        "WIKI_TRACE": "0",
        "CHEMENU_ROOT": "/path/to/instance"
      }
    }
  }
 }
 ```
 `CHEMENU_ROOT` says **which** wiki is served. Without it, the server takes the checkout its own
 package sits in. That is enough for a single instance, but with several corpora it is safer to always
 set it. The process speaks MCP over stdin and stdout and prints nothing of its own, which is correct.
 ## Running it as a service
 Deployed, the server speaks `streamable-http`, the only transport a reverse proxy can sit in front
 of. The command a service unit or container runs looks like this:
 ```bash
 WIKI_TRACE=0 CHEMENU_ROOT=/srv/chemenu \
  tools/.venv/bin/python -m chemenu.mcp \
    --transport streamable-http --host 0.0.0.0 --port 8000
 ```
 The endpoint is then `http://<host>:8000/mcp`. `--host 0.0.0.0` is deliberately not the default:
 without it the server binds to loopback, which is right locally and wrong in a container, where the
 proxy has to reach it. If you set it, make sure something stands in front. `sse` is not offered. It
 is the superseded remote transport, and building on it now would only postpone the switch.
 ## Authentication in front of it
 **The server does not authenticate on its own, by design.** A request that is not properly
 authenticated should never reach the Python process at all. The authentication is a Traefik
 ForwardAuth middleware:
 > **<https://gitea.nehmer.net/torben/gitea-mcp-forward-auth>**
 In short, it checks `Authorization: Bearer <token>` against SHA-256 hashes of allowed tokens. It
 answers `200` for a valid token and `401` for a missing or wrong one, and always leaves
 `GET /healthz` open. Plaintext tokens appear neither in the configuration nor in the log, only
 hashes and a short fingerprint. It is configured with `AUTH_PROXY_TOKEN_HASHES_DIR` (a directory with
 one file per token hash, which suits a Kubernetes secret volume) or `AUTH_PROXY_TOKEN_HASHES` (a
 comma-separated list). The README there has the details, reference manifests and a test script.
 To create a token hash:
 ```bash
 echo -n "my-token" | sha256sum | awk '{print $1}'
 ```
 **Rate limiting belongs in the same place,** in front of the process and beside the
 authentication. It does not belong in the Iteration Budget Gate. That gate stops an *agent session*
 from iterating over the wiki's state unnoticed, which is why retrieval is exempt from it. Using it
 as a rate limiter would water it down.
 ## Keeping the served tree current
 The server reads the working tree, and a stale checkout answers confidently and wrongly. So **every
 answer carries the commit** it was computed from:
 ```json
 { "commit": "<40-character SHA>", "as_of": "<ISO-8601, UTC>", "count": 3, "...": "..." }
 ```
 A timer beside the server keeps the tree current by polling: a fetch, then a hard reset to the
 remote branch. The two commands, and why the hard reset is load-bearing, are in the instruction's
 sync step. Polling rather than a webhook, because it needs no inbound endpoint and no signature
 check, which is a smaller attack surface than the thing a webhook would optimise. **Never add
 `git clean` to that timer.** The reset leaves every gitignored path alone, which is what keeps the
 `submit` quarantine and any traces intact. A clean would silently delete a submission nobody has
 reviewed yet.
 ## Optional: the submit path
 Without this, `submit` does not exist as a tool - not unused, but not registered. A file
 `.wikitool-upload.json` in the served corpus turns it on:
 ```json
 {
  "schema": 1,
  "identity_header": "X-Forwarded-User",
  "max_bytes": 10485760,
  "allowed_extensions": [".md", ".txt", ".pdf", ".html", ".csv", ".json", ".png", ".jpg"],
  "quota": { "submissions_per_day": 20, "bytes_per_day": 52428800 }
 }
 ```
 Every field is required, and none has a built-in default except `identity_header`. A malformed file
 stops the server from starting. It never means "no limits": the failure deliberately goes the safe
 way. Size and quota are your deployment's decision, not defaults worth copying blindly.
 **With `submit` on, the middleware has a second duty.** It has to set the identity header itself, on
 every authenticated request, and discard any copy the client sent. The server trusts that header as
 the value for `submitter`. A header the client could set itself would be a claim, not an identity.
 If `identity_header` names a header the middleware does not set, every submission is refused for
 lack of an identity.
 Submitted files land in `mcp-upload/<id>/`, which is gitignored and read by no other command. From
 there a human promotes or rejects them, in the same checkout as the server rather than in its
 process. That review is part of
 [ingesting a source](ingest-a-source.md#a-document-submitted-from-outside).
 ## Checking that it works
 The quickest test without a client starts the server over stdio, lists its tools and asks one
 question:
 ```bash
 cd tools && WIKI_TRACE=0 .venv/bin/python - <<'EOF'
 import asyncio, os
 from mcp import ClientSession, StdioServerParameters
 from mcp.client.stdio import stdio_client
 async def main():
    params = StdioServerParameters(
        command=".venv/bin/python", args=["-m", "chemenu.mcp"],
        env={"WIKI_TRACE": "0", "PATH": os.environ["PATH"]},
    )
    async with stdio_client(params) as (r, w):
        async with ClientSession(r, w) as s:
            await s.initialize()
            print("Tools:", [t.name for t in (await s.list_tools()).tools])
            out = await s.call_tool("status", {})
            d = getattr(out, "structuredContent", None) or out.structured_content
            print("Pages:", d["pages"], "| Commit:", d["commit"])
 asyncio.run(main())
 EOF
 ```
 Expected output, roughly:
 ```text
 Tools: ['search', 'types', 'describe_type', 'lint', 'status']
 Pages: 176 | Commit: 576df2cdddc96614a7e6641e562022d52112d411
 ```
 Then cross-check against the CLI. Both have to give the same answer:
 ```bash
 tools/wikitool search "<term>" --json
 ```
 ## Troubleshooting
 **`ERROR Telemetry is on and would write into the served checkout`**: expected behaviour, not an
 installation fault. Set `WIKI_TRACE=0`, or point `WIKI_TRACE_DIR` outside the corpus.
 **`ModuleNotFoundError: No module named 'mcp'`**: the optional dependency is not installed, or
 the client starts a different Python than the instance's. Give the client the absolute path to
 `tools/.venv/bin/python`.
 **`"commit": null` in every answer**: the served tree has uncommitted changes. Either the sync is not
 running, or something writes into the corpus that has no business there. The five read tools never
 write. `submit`, when it is on, writes only to `mcp-upload/`, which is gitignored and so is never a
 cause of `"commit": null` either.
 **`commit` names an old revision**: the sync timer is not running.
 **The server answers differently from `wikitool`**: that is a defect, not a configuration
 difference, since both go through the same functions. First check that both point at the same root.
 `CHEMENU_ROOT` is easy to set for one and not the other.
 **Not reachable from outside**: without `--host 0.0.0.0` the server binds to loopback. If it is
 reachable but every call gets `401`, the middleware is working correctly and the token is wrong.
 ## What is deliberately not here
 Deployment specifics - the cluster, ingress hosts, the secret store, the GitOps source - are
 private infrastructure, and this repository is public.
 There is no container image for the server yet. Until there is, the path above - the venv,
 `python -m chemenu.mcp`, a proxy in front - is the complete one. With `submit` on, `mcp-upload/`
 has to survive restarts the same way the rest of the checkout does. Otherwise a submitted file that
 nobody has reviewed yet loses its quarantine.

 # Trace and score agent sessions
 Record what an agent did in a session, read the record back, and score it. A score covers the state
 the session left the wiki in and how it got there: whether it repeated a refused call, or passed a
 gate's flag without that gate ever refusing. Why this exists, what the trace contains, and what a
 score means are covered in [telemetry-and-evaluation.md](../explanation/telemetry-and-evaluation.md).

 <!-- /wikitool:toc -->
 ## What you prepare
 **Turn tracing on, if it is off.** It is on in a clone of the origin repository and off in an
 instance installed from a release. `tools/wikitool doctor` reports which state this checkout is in,
 and why. To turn it on for one checkout, create `.wikitool-telemetry.json` at the root:
 ```json
 { "enabled": true }
 ```
 The file and its other keys are in the [configuration reference](../reference/configuration.md#telemetry).
 Everything stays on this machine: traces land under `reports/telemetry/`, which is gitignored, and
 no exporter is configured.
 **Scope the session to the task.** Every source of events joins on one session id. Setting it
 yourself keeps one task in one trace:
 ```bash
 export WIKITOOL_SESSION_ID="my-task"
 ```
 [instructions/session-setup.md](../../instructions/session-setup.md) has the line for each shell,
 and what to do on a harness that starts a fresh shell for every command.
 ## Reading a session back
 ```bash
 tools/wikitool eval sessions                       # which sessions have a trace
 # what did that session do?
 jq -r '[.ts, .source, .event, (.attrs.command // .attrs.tool_name // "")] | @tsv' \
  reports/telemetry/my-task/trace.jsonl
 # how well did it do it?
 tools/wikitool eval score --session my-task
 tools/wikitool eval score --session my-task --save  # also write the scorecard under reports/evals/
 ```
 Both `eval` commands only read, and neither counts against the session's call budget: reading back
 what a session did is not iterating on the wiki. Their options are in the
 [telemetry command reference](../reference/commands/telemetry.md).
 To see how a harness hook payload would be recorded, feed one in by hand without writing anything:
 ```bash
 echo '{"session_id":"x","hook_event_name":"post_tool","tool_name":"bash"}' \
  | tools/trace_ingest.py --source mistral-vibe --dry-run
 ```
 ## What each harness can report
 `wikitool` records its own calls on every harness. What the agent did *between* those calls -
 file reads, searches, shell commands, prompts - comes from the harness's hooks, and harnesses differ
 a lot in what they offer. Verified against vendor documentation on 2026-08-23:
 | | Claude Code | Copilot CLI | VS Code Chat | Mistral Vibe |
 |---|---|---|---|---|
 | Hook events | ~30 | 14 | none | 3 (`pre_tool`, `post_tool`, `post_agent`) |
 | Session start/end hook | yes | yes | - | **no** |
 | Prompt submit hook | yes | yes | - | **no** |
 | Which instructions loaded | yes (`InstructionsLoaded`) | no | no | no |
 | Block / rewrite a tool call | yes | yes | - | yes |
 | OTel to your own collector | yes | via MDM `telemetry` | no | **no** - `enable_otel` targets Mistral Studio only |
 | `TRACEPARENT` to subprocesses | yes | undocumented | - | undocumented |
 | Programmatic mode | `-p`, `stream-json` | `-p` | no | `-p`, `--output streaming` |
 | Isolated config home | to be confirmed | `COPILOT_HOME` | no | `VIBE_HOME` |
 | Local session log | `~/.claude/projects/*.jsonl` (unstable format) | `~/.copilot/session-state/<id>/events.jsonl` | chronicle SQLite | `$VIBE_HOME/logs/` (no format guarantee) |
 | Wired up here | **partial** - `.claude/settings.json` (`UserPromptSubmit` + a `permissions.ask` rule on the clearing publish) | **yes** - `.github/hooks/wiki-trace.json` | **yes** - `tools/import_chronicle.py` | **yes** - `.vibe/hooks.toml` |
 A rule that needs an event a harness cannot report is shown as *skipped*, not as passed or failed.
 ### Claude Code
 `.claude/settings.json` wires `UserPromptSubmit` to `tools/trace_ingest.py`, through
 `tools/trace-hook` like every hook here. That gives the trace its turn boundaries, which the rule
 `clearance-ended-the-turn` needs. Without a `prompt.submitted` event it reports "cannot say"
 instead of a verdict.
 **No `PreToolUse` decision hook is wired, and that is a finding, not an oversight.** Verified against
 the live CLI on 2026-08-27: a `PreToolUse` hook that returns
 `hookSpecificOutput.permissionDecision: "ask"` does **not** override a matching `permissions.allow`
 rule. Permissions are evaluated before the hook's decision, so a hook cannot force a confirmation
 prompt on a command that is already allowed. A `permissions.ask` rule *does* win, which is why
 `.claude/settings.json` carries one on the `--confirm` form of `publish`
 (`Bash(tools/wikitool publish --confirm:*)`). The clearing call prompts, and ordinary publishes below
 the threshold do not. It is a prefix match, so it depends on `--confirm` coming first, which is why
 `publish` always prints its re-run line in that order. Treat it as a useful second line, not a
 guarantee: an agent that reorders the flags gets around it.
 ### Copilot CLI
 [.github/hooks/wiki-trace.json](../../.github/hooks/wiki-trace.json) is committed, so a clone
 brings its own tracing. Eleven events go to `tools/trace_ingest.py`. `disableAllHooks` in
 `.github/copilot/settings.json` turns them off without deleting anything. `userPromptSubmitted` is
 among them, so `clearance-ended-the-turn` can be scored on Copilot CLI with no change.
 A `preToolUse` entry that forces a decision on the clearing call would first need Copilot's own
 decision-document schema verified against a live CLI. That has not happened, and an adapter that
 cannot be verified is not written.
 Four details of the hook configuration matter. The first two hold for all three harnesses that have
 hooks:
 - **The interpreter is the venv's, never the script's shebang.** Each `bash` command is
  `./tools/trace-hook ...`, which runs `trace_ingest.py` with `tools/.venv`'s Python in either venv
  layout. Each `powershell` command names `tools\.venv\Scripts\python.exe` directly. On Windows in
  Git Bash, the shebang's `python3` was the Microsoft Store alias, which made every hook a silent
  no-op. Before the preflight has created the venv, `trace-hook` records nothing and exits 0.
 - **`./tools/trace-hook` has a PowerShell twin, `tools/trace-hook.ps1`.** PowerShell on Windows
  resolves the string to the `.ps1` first. Without the twin, it hands the sh script to a file
  association, and Windows asks which app should open it - on every hook event. Copilot CLI also
  reads `.claude/settings.json` and runs its single `command` under PowerShell on Windows, so a
  `bash` field alone does not keep the string out of PowerShell. The twin follows the sh script's
  rules - venv Python, silent without a venv, exit 0 whatever happens - and stays parseable by
  Windows PowerShell 5.1, because VS Code starts hooks under 5.1.
 - **Every command ends in `|| true`.** `preToolUse` hooks fail closed: a non-zero exit denies the
  tool call. Without the guard, a missing interpreter would turn the observer into a blocker that
  refuses every tool call in the session. Timeouts fail open, so the 5-second `timeoutSec` is no
  hazard.
 - **The event name is passed explicitly.** Copilot serves two payload dialects: camelCase event
  names give camelCase fields, and PascalCase names give the snake_case shape that VS Code and Claude
  use. `--event` means the mapping does not depend on which one a configuration chose.
 ### VS Code Chat
 VS Code Chat has no hooks, so nothing observes a session while it runs. Its chronicle store
 (`session-store.db`, the same schema as Copilot CLI's) keeps sessions, turns and touched files, and
 [tools/import_chronicle.py](../../tools/import_chronicle.py) rebuilds a trace from it afterwards:
 ```bash
 tools/import_chronicle.py --dry-run     # this repository's sessions
 tools/import_chronicle.py --session 0f1e2d3c
 ```
 The store starts empty, and `/chronicle reindex` fills it. That command also syncs session data to
 your GitHub account, so run it deliberately rather than from a script. A rebuilt trace marks itself
 `reconstructed: true`, and its `completeness` names `tool.post` but not `tool.pre`: the store records
 that a file was touched, not that a tool was about to run.
 ### Mistral Vibe
 [.vibe/hooks.toml](../../.vibe/hooks.toml) declares the three hooks Vibe has, and
 [.vibe/config.toml](../../.vibe/config.toml) keeps the telemetry settings in the repository rather
 than in someone's shell profile. Both were checked against the installed CLI's own loader
 (`mistral-vibe 2.24.2`) rather than against its documentation. What that turned up:
 - **A failing hook cannot block anything.** With `strict = false`, the default, a crash or a timeout
  is only a warning. Only a hook that opts into `strict` can deny a tool call - the mirror image of
  Copilot.
 - **`post_agent` carries no response text,** only the session context. That is why it maps to
  `turn.end` rather than `assistant.message`.
 - **`enable_telemetry` defaults to `true`.** Turning it off is a real change, and it also gates OTel
  export, which needs both flags on. This repository leaves both off: Vibe's `enable_otel` sends
  prompts to Mistral Studio.
 - **Vibe already reads `.agents/skills/` and `AGENTS.md`.** The directory that
  `wikitool instructions sync` publishes is a project-scope skill source for Vibe, so working with
  Vibe needs no adaptation, only a trusted folder.

 # Troubleshoot an instance
 What a common failure means, and what to do about it. During installation itself, the preflight
 names its own stops - what is missing, why, and the command that fixes it - and
 [INSTALL.md](../../INSTALL.md) explains them. This page covers an instance that is already set up.
 For the MCP read server, see the troubleshooting section of
 [Set up the MCP read server](set-up-the-mcp-server.md#troubleshooting).
 ## `tools/wikitool` ends with `STOP - this checkout is not set up yet` (exit 42)
 The preflight has not run in this checkout yet, or not since the last update. Run it:
 ```bash
 tools/preflight.sh
 ```
 In PowerShell 7 on Windows, the call is
 `pwsh -NoProfile -ExecutionPolicy Bypass -File tools/preflight.ps1`. The `-ExecutionPolicy Bypass`
 applies to that one process only and changes no setting.
 [instructions/preflight.md](../../instructions/preflight.md) is the procedure, and its output says
 what to install if anything is missing.
 ## The agent offers no skills (`wiki-ingest`, `wiki-query`, ...)
 `.agents/skills/` and `.claude/skills/` are generated and not committed. Run:
 ```bash
 tools/wikitool instructions sync
 ```
 Then restart the agent session. A harness reads its skills only when the session starts.
 ## `doctor` reports `personalization: FAIL`
 `USER.md` or `SOUL.md` is missing, or still carries the sentinel line from its template. A renamed
 template does not count as a filled one. Ask the agent to run the personalization step of
 [instructions/setup-instance.md](../../instructions/setup-instance.md). For a further clone of an
 older instance, that is the only step to catch up on.
 ## `doctor` reports `environment: WARN`
 `ENVIRONMENT.md` exists but still carries the template's sentinel line. Fill it in (the template is
 `ENVIRONMENT.md.template`) and remove the line, or delete the file. It is optional, and `absent` is
 a valid state.
 ## `new` stops with "No author configured"
 Neither `$WIKI_AUTHOR` nor `git config user.name` is set. Run `git config user.name "<Name>"`, or
 export `WIKI_AUTHOR` ([configuration](../reference/configuration.md)).
 ## `publish` ends with exit 42 (Mass-Update Gate)
 Expected when ten or more files are counted, for example on the very first commit of a new instance
 or after a lint pass. It is not an error. It asks that a human see the output: the complete file
 list and the exact `--confirm <token>` line that publishes once you approve.
 [instructions/gates.md](../../instructions/gates.md) has the details.
 ## `publish` ends with exit 42 (Publish-Remote Gate)
 This checkout has a `.wikitool-remotes.json`, and the remote being pushed to is not listed in it.
 Also not an error: the output names the push URL it would write to and the URLs that are allowed.
 Unlike the Mass-Update Gate, there is **no token and no flag** here. If the target really is right,
 you add its URL to the file yourself. An agent that edits the file to get past the refusal is
 opening a gate on its own initiative, which it must never do.
 ## Setup or an update fails, and you want to report it
 Ask the agent to follow [instructions/bug-report.md](../../instructions/bug-report.md), or call
 `tools/bugreport` yourself. It works the same from Bash, Git Bash and PowerShell. It finds a
 Python 3.8 or newer by itself, skipping the Store aliases `python3` points at on Windows. It needs
 neither the preflight nor a working `wikitool`, and if it finds no Python, it says why.
 The script writes a bundle to `reports/bugreport-<timestamp>/`, with a zip beside it.
 - **What is removed:** secrets, and page titles from everything the script itself produces.
  `--titles` keeps the titles.
 - **What may still be in it:** the session trace is included by default (`--no-trace` leaves it
  out). Like the chronology and the transcripts, it can contain page content and titles. The bundle
  also contains machine, user and path names.
 - **Pseudonymising:** `--pseudonymise` replaces user, host, path, git and remote names with
  placeholders that keep their length, spaces, hyphens and path depth. The agent can then add more
  names - people, companies, customers, projects - with `--bundle … --candidates …`. That is a
  model's judgment, and it leaves a remainder: read the bundle before you share it. The mapping,
  the checklist and the candidates file contain the originals, and they sit beside the bundle,
  never in it.
 Nothing is uploaded anywhere. You choose the channel.

 # Update an instance
 Bring an instance installed from a release up to a newer release of the stack: the tools, types,
 instructions and contracts. Your pages stay yours. The agent carries out the upgrade by following
 [instructions/upgrade-instance.md](../../instructions/upgrade-instance.md), which sets the order of
 the steps, what each one decides, and where the session has to restart. This page covers the
 decision before it, and what you'll see along the way.

 ## What is running, and is there something newer?
 Every instance carries the version of the **stack**, not of its content. It is in `VERSION`, and
 `.wikitool-release.json` beside it records where the release came from and when it was exported.
 ```bash
 tools/wikitool version         # what runs here, and where it came from
 tools/wikitool version check   # is there a newer release?
 tools/wikitool version notes   # what the newest release changes
 ```
 `version check`, `version notes` and `dist upgrade --latest` are the only commands that go to the
 network. All three ask the same release feed: the one named in the stamp, unless
 `WIKITOOL_UPDATE_URL` overrides it. A feed that cannot be reached is reported as an error, **never**
 as "up to date" and never as "no notes".
 ## Read the notes first
 What a version number promises: two versions are compatible when they agree in the *leftmost
 non-zero part*. `0.1.3 → 0.1.4` is a safe update and `0.1.3 → 0.2.0` is not. From `1.0.0` on, the
 same rule reads as the familiar "a MAJOR breaks". `version check` says which case you are in
 (`state: update` or `state: migration`).
 That number only answers whether the new machinery can simply be copied over the old. Whether your
 *content* has to be migrated is a second, independent question. So the release notes of a MAJOR
 carry two separate lines, and both are worth reading before you start:
 - **Breaking Change:** what stops working, and what this instance has to do about it.
 - **Migration:** whether and how the pages are rewritten (`none required` when they are not).
 `version notes` prints both. On an instance it reads them from the release feed, because an
 instance's own `CHANGES.md` is a stub that an update never overwrites. It always asks for the
 **newest** release, so while `VERSION` still names the old one, it answers with a version other than
 the one installed, and says so on stderr. If the feed cannot be reached, the error names the release
 page recorded as `release_url` in `.wikitool-release.json`. `--offline` sends you there directly.
 Why the two questions are kept apart: [version-model.md](../explanation/version-model.md).
 ## What you say
 ```text
 Update this instance to the latest release
 ```
 ## Where the agent stops
 In the order you'll meet them:
 - **The release notes.** The agent shows you both lines before it touches anything. A migration the
  instance already owes from an earlier release is finished first.
 - **A stack file you changed by hand.** `dist upgrade` lists every file that differs from what the
  installed release shipped, instead of overwriting it silently. For each one, you decide: take the
  release's version, or keep yours. Keeping yours means the file is reported again at every future
  upgrade.
 - **The preflight.** A new release may need other tools than the old one. If something is missing,
  the preflight stops with exit 42 and says what to install, exactly as during installation.
 - **The first publish.** The swapped machinery is published on its own, before any content changes.
  That is far more than ten files, so the Mass-Update Gate (exit 42) shows you the list and the
  `--confirm` line.
 - **The session restart.** The running session still holds the *old* `AGENTS.md`, contracts and
  skills, so the agent asks you to restart it before migrating content. The new session picks up
  where the old one stopped.
 - **An offered migration.** A required migration is simply carried out. An *offered* one changes a
  file the instance owns, so taking it or declining it is your decision.
 - **The second publish,** of the migrated content, behind the same gate.
 If a step fails for a reason that isn't obvious, the agent stops and offers you a bug report rather
 than improvising ([Troubleshoot](troubleshoot.md)).
 `doctor` warns as long as the content's version (`kb_version` in `.wikitool-kb.json`) is behind
 `VERSION` and migrations are still open. An instance older than `.wikitool-kb.json` has no such file
 at all. In that case `tools/wikitool migrate baseline <version>` is called once, and nothing is
 guessed.
 ## Where the release comes from, and whom you trust
 `tools/wikitool dist upgrade --latest --expect <version>` asks the release feed for its newest
 release, downloads the tarball and its `.sha256` into a scratch directory, checks one against the
 other and applies the release. The scratch directory is removed on every exit, including
 `--dry-run`. `--expect` is the version `version notes` showed you: the feed only knows its *newest*
 release, and `--expect` refuses **before** downloading if a newer one has appeared since, rather
 than applying something nobody read. Pre-releases (`-beta.N`) need `--pre`.
 **What the checksum does, and what it does not do.** The `.sha256` comes from the same feed as the
 tarball. It protects against a damaged transfer, not against a compromised feed. Whether a release
 is genuine rests on your trust in the host whose feed the instance asks (`update_url` in the stamp).
 Nothing forces https. A configured `http://` feed is a deliberate choice. `WIKITOOL_UPDATE_TOKEN`
 is sent only to downloads on the same host as the feed.
 **Offline, or with a tarball from someone else:** put the tarball and its `.sha256` side by side,
 and the agent passes the file instead of `--latest` (`dist upgrade <tarball>`). A tarball has to
 unpack to exactly one top-level directory, which is the shape the release workflow builds.
 ## Two first-time cases
 **The first jump to a release that knows `--latest`:** the option does not exist in the instance
 yet, because the instruction there belongs to the release being left. Fetch the tarball and the
 `.sha256` once from the release page, put them side by side, and run `dist upgrade <tarball>`. From
 the next release on, the instance has `--latest` itself.
 **The first jump to `4.5.0` or later:** `dist upgrade` itself does not exist in the instance yet,
 because it arrived with `4.5.0`. Use the tool from the unpacked *new* tarball and point it at the old
 instance:
 ```bash
 tar -xzf chemenu-stack-<version>.tar.gz
 CHEMENU_ROOT="$PWD" chemenu-stack-<version>/tools/wikitool \
  dist upgrade chemenu-stack-<version>.tar.gz --dry-run
 ```
 `CHEMENU_ROOT` tells the package which corpus to work on ([configuration](../reference/configuration.md)).
 Without it, the package would take the unpacked tarball itself for the instance. From the second
 upgrade on, the instance carries the command and the instruction itself.
 ## Pitfalls
 - An instance without a local `.wikitool-release.json`, or with one that has no `files` block (from
  before `4.5.0`), gives `dist upgrade` nothing to detect a local change against, so it refuses
  the swap. There is no repair for that today.
 - Given a tarball or directory, `dist upgrade` downloads nothing. Only `--latest` downloads.
 - To follow the swap by hand anyway, perhaps with a tool `wikitool` cannot run, use the file list in
  the `files` block of `.wikitool-release.json`. The exceptions - `kb/CONVENTIONS.md`, every
  `kb/*/COLLECTION.md`, `.wikitool-kb.json` - are in the
  [`dist upgrade` record](../reference/commands/distribution-and-versioning.md#dist-upgrade), along
  with what the command classifies and refuses.

 | `WIKI_TRACE_KEEP_SESSIONS` | How many session directories retention keeps; beats the file's `keep_sessions` | 250 |
 ## Telemetry
 **Telemetry is off in an instance.** Every instance carries the `.wikitool-release.json` of its
 release, and that is how `chemenu.telemetry.policy` recognises that nobody asked for telemetry. The
 same holds for every further clone of the instance, because the file is committed with the first
 publish. Only a clone of the origin repository, used to develop the stack, has no stamp. There the
 traces are the instrument the stack measures itself with, and they are **on**.
 To turn the default around, create `.wikitool-telemetry.json` at the root. It is per checkout and
 gitignored, with no `.template`, like `.wikitool-remotes.json`:
 ```json
 { "enabled": true, "max_session_bytes": 5242880, "keep_sessions": 250 }
 ```
 All three keys are optional. `WIKI_TRACE` still overrides `enabled` in both directions and beats
 this file. `wikitool doctor` reports the current state: on or off, why, and how much has been
 recorded against both caps. What the caps do and what never reaches a trace:
 [telemetry-and-evaluation.md](../explanation/telemetry-and-evaluation.md).
 ## Tool paths
 **The preflight writes this file, not you.** `.wikitool-tools.json` at the root holds the absolute
 paths of Python, git and ripgrep, as the preflight found them on this machine. `wikitool` starts git
 and rg from there instead of from `PATH`. It is per checkout and gitignored, because a path on one
 machine says nothing about the next.
 If the file is missing or incomplete, `tools/wikitool` does not start (exit 42) and names the
 preflight. If a tool sits somewhere the preflight does not look, name it:
 `tools/preflight.sh --set rg=<path>`, or in PowerShell
 `pwsh -NoProfile -ExecutionPolicy Bypass -File tools/preflight.ps1 --set rg=<path>`. Never edit the
 file by hand. `doctor` reports under `tool-paths` whether every path still works.
 ## Allowed push URLs
 `.wikitool-remotes.json` at the root restricts where `publish` may push, per checkout and
 gitignored:
 ```json
 { "allowed_push_urls": ["git@example.org:me/my-wiki.git"] }
 ```
 Without the file, any remote is allowed. With it, `publish` refuses with exit 42 (the Publish-Remote
 Gate) before pushing to a URL not on the list. A malformed file is an error, not permission. Only you
 edit this file. The gate has no token and no flag, and an agent that edits the list to get past a
 refusal is opening a gate on its own initiative.
 ## Task tracker
 **Optional.** The weekly review (`tools/wikitool review`, skill `gtd-weekly-review`) checks the
 project pages under `kb/gtd/` against a task tracker. Which tracker that is goes in
 `.wikitool-tasks.json` at the root. Like the telemetry and remotes files, it is per checkout and has
 no `.template`, and it is **gitignored as soon as a token is in it**. Without the file, no tracker is
 configured, which is a valid state, not an error. A broken file, on the other hand, is a `FAIL`: an
 unreadable configuration must never pass as "no tracker".
 ```json
 {
  "schema": 1,
  "provider": "superproductivity",
  "thresholds": {
    "stalled_waiting_days": 14,
    "unpaged_project_weeks": 3,
    "someday_stale_months": 5
  },
  "superproductivity": {
    "access": "api",
    "api_base_url": "http://127.0.0.1:3876",
    "api_token": "<token from the SP settings>"
  }
 }
 ```
 `provider` picks the adapter. The stack ships `superproductivity` and `caldav`.
 The `thresholds` block holds the review's three thresholds (configuration, not schema): when a
 waiting-for counts as overdue, how old a tracker project without a `kb/` page has to be before it is
 reported, and when a someday item counts as stale. A value the provider cannot supply at all - a
 waiting item with no follow-up date, a tracker project with no creation date - is not skipped silently
 but reported as its own finding (`waiting_no_follow_up`/`project_age_unknown`).
 The provider block of the same name holds the connection details.
 ### Super Productivity
 `access` is **mandatory and has no fallback**. It chooses between two mutually exclusive ways in:
 - **`access: "snapshot"`** for an instance run headless: it reads only the newest backup snapshot
  under `backups_dir`. That works without the app running, but only reads. The tracker cannot be
  written from there.
  ```json
    "superproductivity": {
      "access": "snapshot",
      "backups_dir": "~/.config/superProductivity/backups"
    }
  ```
 - **`access: "api"`** for a desktop instance: it talks only to the local REST API. That answers only
  while the app runs, but it gives the current state and carries the write path. `api_token` is
  required, because every endpoint except `GET /health` demands `Authorization: Bearer <token>`.
 The block names only the fields of its own way in. A `backups_dir` beside `access: "api"`, or an
 `api_token` beside `access: "snapshot"`, is refused when the configuration is read, not ignored.
 What can write:
 - `tools/wikitool new project` creates a tracker project of the same name only with `access: "api"`,
  and even there not automatically. The command stops (exit 42) and asks a human to create it, then
  continues with `--resume`.
 - `tools/wikitool task new` creates a single item without a `kb/` page.
 - `tools/wikitool task close --id` marks an item done. It never deletes one.
 With `access: "snapshot"`, all three refuse completely with exit 1, because the tracker is read-only
 from there. `tools/wikitool task list --project` only reads, so it answers with either `access`.
 ### CalDAV
 `caldav` is the standards-based second adapter (RFC 4791/5545). It is verified against Nextcloud
 Tasks, with iOS *Reminders* as the mobile client, and built for that split: tick items off on the
 phone, maintain them at the desk. Unlike Super Productivity, there is only one way in. CalDAV is
 always a network access, so no `access` field is needed:
 ```json
  "caldav": {
    "url": "https://<host>/remote.php/dav/calendars/<user>/",
    "username": "<login>",
    "app_password": "<Nextcloud app password>",
    "inbox_list": "Inbox",
    "someday_list": "Someday",
    "exclude_lists": ["<an existing list that is not a project>"]
  }
 ```
 - `url` points at the account's CalDAV calendar home set. It may be an alias - Nextcloud accepts a
  short name there - because every later address comes only from the `href`s the server returns,
  never from this URL joined with a name.
 - `username` is the login name, which can differ from the user id in the URL. A Nextcloud app
  password is recommended, not the account password.
 - `inbox_list` and `someday_list` name the two fixed lists, exactly one of each per instance.
 - `exclude_lists` leaves out existing plain task lists that are not projects. A list with a
  `VEVENT` component never counts as a project anyway.
 A project is a list whose only supported component is `VTODO`. `tools/wikitool new project` creates
 it automatically with `MKCALENDAR` - without asking, unlike Super Productivity, because CalDAV has a
 real create command for lists. The uniqueness check runs against **every** list in the account,
 including excluded lists, the inbox, someday and mixed calendars. If a new name collides with any of
 them, nothing is created and the collision is named. Renaming the existing list in Nextcloud stays a
 manual step.
 `task new` and `task close` work without restriction on `caldav`, which has no read-only mode like
 `access: "snapshot"`. When ticking an item off, `task close` changes only `STATUS`, `COMPLETED`,
 `PERCENT-COMPLETE`, `LAST-MODIFIED` and `DTSTAMP` on the existing `.ics` resource. Every other
 property, including an unknown `X-` property or an alarm, is kept unchanged. A resource that changed
 since it was read (an ETag conflict) is not written, and the command stops with exit 1. Nothing is
 ever deleted. The lists of finished projects stay after archiving, because the adapter never deletes
 a list. Remove them by hand in Nextcloud when you want to.
 ## MCP submissions
