F1 [blocking]: a suggestion whose anchor matched via normalization could never
be applied (spurious 409). The comment mark lands on the doc's ACTUAL text
(Docmost auto-converts to typographic quotes/dashes/nbsp), but the stored
selection — used as expectedText at apply — was the raw ASCII agent input
(+substring(0,250)). So replaceYjsMarkedText's strict joined!==expectedText
always failed and threw "text changed" though nobody edited. Fix: new pure
getAnchoredText(doc, selection) reconstructs the exact raw doc substring the mark
covers (slicing identical to spliceCommentMark); on the suggestion path
client.createComment stores THAT as selection, so expectedText equals the marked
text and apply returns applied:true. Live anchoring still uses the raw agent
selection (normalization still finds the anchor). Truncation raised 250->2000
(+ DTO @MaxLength(2000)) so the anchored substring is never cut below the mark
span. Ordinary comments unchanged. AI-chat shares client.createComment, so
covered. Regression tests: getAnchoredText raw-vs-ASCII; create payload selection
is the typographic substring; apply with typographic expectedText -> applied.
F2 [blocking]: added comment.controller.spec.ts pinning that validateCanEdit runs
before applySuggestion (Forbidden -> applySuggestion never called; happy path ->
called; missing comment -> 404 without authorizing).
MCP 448 pass; server comment+yjs 54 pass. MCP build/ rebuilt.

Agents can attach a suggested replacement when creating an inline comment, via
both the MCP create_comment tool and the AI-chat createComment tool.
Because applying a suggestion edits the EXACT anchored text, an ambiguous anchor
would let Apply corrupt the wrong occurrence. So when suggestedText is set the
selection must occur EXACTLY ONCE:
- new countAnchorMatches(doc, selection) counts occurrences across all blocks
(same normalization/traversal as canAnchorInDoc), counting occurrences (2 in
one block => 2) — stricter than block-count, never under-counting distinct
occurrences (false-unique is the dangerous direction).
- client.createComment gains suggestedText: a pre-check (getPageJson +
countAnchorMatches: 0 => not-found, >=2 => ambiguity error) before create, and
an AUTHORITATIVE live check inside the anchoring mutation that recomputes on the
live doc and, if != 1, aborts and rolls back the just-created comment (reusing
the existing safeDeleteComment "anchor not found" path). Ordinary comments keep
first-occurrence behavior unchanged.
- suggestedText is rejected on a reply or without selection in all three layers
(MCP handler, MCP client, AI-chat tool), mirroring the server DTO/service.
- filterComment surfaces suggestedText/suggestionAppliedAt/suggestionAppliedById.
- DocmostClientLike.createComment signature updated. MCP build/ rebuilt.
Tests: countAnchorMatches (0/1/N, within/across/nested block, span nodes,
quote normalization); createComment (ambiguous refused pre-create, reply and
no-selection rejected, unique succeeds and forwards suggestedText, filterComment
surfaces it); ai-chat schema accepts suggestedText. MCP 443 pass; ai-chat 601 pass.

The in-app AI chat hardcoded type='page' and the shared createComment
swallowed anchoring failures silently, so agent comments never got a
text anchor/highlight.
- Forbid page-type comments for the agent: top-level comments are always
inline and require an exact `selection`; replies inherit the parent
anchor (stored as the historical `page` type).
- Throw and roll back the just-created comment when the selection cannot
be anchored, instead of leaving an orphan unanchored comment.
- Add comment-anchor module: text normalization (smart quotes, dashes,
nbsp, collapsed whitespace) and matching across adjacent text nodes
within a block, so selections crossing inline-code/bold/link anchor.
- Update create_comment (MCP) and createComment (ai-chat) tool schemas
and descriptions; add unit + mock-HTTP orchestration tests.
