- footnote-sync: remove the now-dead `refReids` (CollisionPlan field, local,
return, the 6a consumer loop) — references are never re-id'd under reuse, so it
was dead structure on the hot reconciliation path. Rewrite the stale comments
(plugin header, step 0, refOccurrences field) that still described the old
"duplicates re-id'd so both survive" model to the reuse model.
- Shared footnote lexer: new packages/mcp/src/lib/footnote-lex.ts
(lexFootnoteLines + forEachFootnoteReference). extractFootnotes (collaboration)
and analyzeFootnotes now consume the SAME fence-aware lexer, so "the analyzer
sees exactly what the importer keeps/strips" is structural, not comment-kept.
Removed the duplicated DEF_RE/fence machine from both consumers.
- Tests: new mock test for the footnoteWarnings plumbing on createPage (problems
-> field present; clean -> omitted); new paste-reuse case for TWO colliding
pasted definitions (reservation -> distinct ids). Updated the derive-id golden
test header (no MCP copy / parity test anymore).
- CHANGELOG: [Unreleased] entries for footnote reuse (Changed, supersedes 0.93.0)
and footnoteWarnings (Added).
editor-ext 129, MCP 301, server roundtrip 2; client+server tsc clean.

Footnotes were strict 1:1: a repeated `[^a]` reference was treated as a
collision and re-id'd to `a__2`, and a reference with no definition synthesized
its own empty one — so an agent-authored article with reused labels produced
dozens of empty `kowiki__N` footnotes. Move to Pandoc REUSE semantics and add
non-fatal import diagnostics.
Reuse (core):
- resolveCollisions (footnote-sync): repeated references sharing an id are REUSE
(recorded once in document order, never re-id'd) — one number, one shared
definition. Only a duplicate DEFINITION is re-id'd deterministically and, with
no matching reference, dropped by the existing orphan policy (first-wins).
CollisionPlan.refReids is now always empty (harmless no-op downstream).
- extractFootnoteDefinitions (marked) and extractFootnotes (MCP): duplicate
definition ids are FIRST-WINS (keep first, drop rest); reference markers are
never rewritten. Removed the marker-rewriting and the now-dead deriveFootnoteId
mirror + helpers from the MCP path.
Import diagnostics:
- New analyzeFootnotes() (MCP): fence-aware pure scan reporting dangling
references, empty/duplicate definitions and `[^id]` markers inside table rows.
- createPage / updatePage / importPageMarkdown now attach `footnoteWarnings`
(only when non-empty) so an agent can fix its markup; the page is still created.
Paste-reuse:
- footnotePastePlugin remaps only ids the pasted slice DEFINES (a colliding
definition); a pasted lone reference to an existing id keeps it (reuse).
Tests: reuse/first-wins rewrites of footnote.test, footnote-markdown.test,
footnote.marked.orphan.test and the MCP footnotes.test; new footnote-paste.test
(editor-ext) and footnote-analyze.test (MCP). Deleted derive-id-parity.test.mjs
(the MCP no longer derives ids; editor-ext's deriveFootnoteId keeps its own
golden test). editor-ext 128, MCP 299, server roundtrip 2, client views 3,
client+server tsc clean.
Two review suggestions applied: corrected a stale "duplicated in MCP" comment and
the dangling-reference warning wording.
Note: the multi-backlink editor UI (a reused definition linking back to each of
its references) is deferred to a follow-up — this PR delivers the data-integrity
core (reuse + warnings + paste-reuse). Forward links and numbering already reuse
correctly; the backlink currently targets the first reference.
