Workshop: link-taxonomy-migration

• Run key: link-taxonomy-migration (this directory's name - there is no other identifier)
• Input: none - this run is not an ingest
• Started: 2026-09-02
• Session id form: WIKITOOL_SESSION_ID="link-taxonomy-migration/u<N>", one per unit
• Issue: Gitea #40, sections Label werden Enum and Toolgeführte Blöcke

Goal

Move every relationship in kb/ from free-text German prose in a body bullet to a machine value in related:, and every tool-owned body region from heading-matching to a marker pair. Afterwards the compiler contains no heading text and no relationship label, and lint can enforce the vocabulary because there is one.

Why this is assisted and not mechanical

Measured on 2026-09-02, against the corpus rather than against the documentation:

Pages	180
Distinct relationship labels in body bullets	152
Labelled bullets	337
Labels occurring exactly once	102
Top 20 labels cover	167 of 337
Bare - [[X]] bullets under ## Siehe auch	555
...of those, provably redundant (a labelled edge already exists)	353
...of those, the only connection between the two pages	202, across 63 target pages

kb/CONVENTIONS.md documents thirteen labels. Nothing ever checked that, and the corpus does not follow it - so there is no mapping table to apply, and roughly 539 edges need a judgment call each. A large minority are reverse directions (Verwendet von 20x, implementiert durch, Ersetzt durch), which under authored directional edges are exactly the edges that stop being stored and start being rendered.

Rejected alternative, recorded so it is not re-proposed: map the top 20 mechanically and set everything else to see-also. That would start the new taxonomy with ~370 of ~539 edges on its weakest label - the verwandt mit sediment this whole change exists to end, re-created as the documented initial state.

Closes when

Every unit in plan.md is published, and:

• wikitool lint reports zero unlabelled edges and zero labels outside the authorising collection's outbound: block
• wikitool migrate verify --from <pre-migration rev> reports no wikilink or citation count change, and no unbalanced marker
• wikitool migrate done 4.0.0 --pages <N> has run

Checklist

• u0 mechanism - taxonomy, links.py, blocks.py, xref rewrite, lint checks, links show for the inbound view, deletion of the matching layer. No page touched.
• u1 kb/entities/ (systems, tools, technologies) - 57 pages, 199 edges, run as five sub-sessions (u1, u1-technologies, u1-technologies-2, u1-tools-1, u1-tools-2, u1-close) against one 60-call-per-session ceiling; published together as commit b137359. Deferred cross-collection edges recorded in glossary.md for u2/u3.
• u2 kb/entities/ (projects, people) + kb/comparisons/ - 16 pages, ~45 edges, single session (link-taxonomy-migration/u2, closed as u2-close). Discovered comparisons pages carry no related: field at all (only entities:, unlabelled by the type spec); labelled the prose by hand instead. Confirmed taxonomy gap for person-authored/extended relationships, resolved as see-also throughout - see glossary.md.
• u3 kb/concepts/ - 80 pages, ~250 edges, run as seven sub-sessions (u3, u3-b2..u3-b7, close u3-close) against the 60-call ceiling, including one gate-forced pause mid-batch resumed with explicit user approval. Two self-caught defects: 14 pages left unlabelled after a wrong "already covered elsewhere" call (fixed via lint --full's unlabelled-edges report), and one real content loss - a cited, substantive Verwandte Concepts line deleted alongside a bare wikilink during prose cleanup, caught by migrate verify's cite-refs diff and restored. Published as commit a35c94e. See glossary.md for the add-is-safe/remove-is-risky mechanism note this unit established.
• u4 kb/sources/ - zero page edits needed. types/source.md declares no related: field (only entities:/concepts:, same structural gap as comparisons), and all 27 source pages already had those fields correctly populated via xref link-source at ingest time - there was never an unlabelled edge here to fix. migrate verify --from 177c7e9 --path kb/sources: 0 findings. No commit, no session id spent beyond the check itself. See glossary.md.
• u5 close-out - migrate done, version bump, CHANGES.md, workshop close

Measured after u0

lint against the corpus, with the machinery in place and no page touched:

Finding	Count
unlabelled_edges	480 - every related: entry, since none carries a label yet
unauthorised_labels	0 - nothing declares a label at all, so nothing can be unauthorised
malformed_edges	0
unbalanced_markers	0
orphan_pages	1 (GRUB, pre-existing)
broken_links, dangling_frontmatter_refs, schema_validation_errors	0

480 is the number u1-u4 have to bring to zero. It is larger than the 337 labelled body bullets because related: also holds entries whose bullet was lost or never written - which is itself a finding: the frontmatter and the body had already drifted apart under the old model, and nothing could see it while the label lived only in the prose.

Open decisions

• Settled 2026-09-02: edges are directional; the reverse edge is authored only when it is a primary statement on its own page. The inbound view is rendered, not stored.
• Settled 2026-09-02: the 353 provably-redundant ## Siehe auch edges are dropped mechanically. The 202 that are the only connection get a real label each, or are dropped with a reason - never converted to see-also in bulk.
• Settled 2026-09-02: labels are not localized. - **depends-on:** [[Hermes]] is what a German page carries.
