feat: docs/ carries the operator's how-to guides, a configuration reference and the architecture and telemetry explanations carved out of README.md, INSTALL.md, INSTALL-MCP.md and EVALS.md; the last two retired (#190)

+# 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.

+  repositories.
