F5: document the #184 feature under [Unreleased] -> Added — runs survive a
browser disconnect, reconnect-and-live-follow, POST /ai-chat/run + /ai-chat/stop,
the settings.ai.autonomousRuns flag, the ai_chat_runs table, and the phase-1
single-instance constraint.

F3: the load-bearing `effectiveSignal = handle.signal` -> streamText
`abortSignal` had no test; a regression to the socket-bound signal would pass
green and silently break Stop + durability. Add a happy-path test (runHooks.begin
returns the run signal -> streamText is driven with abortSignal === handle.signal,
NOT the socket) and a legacy-path test (no runHooks -> the socket signal is used).

F1 (DECISION C): make the crash-recovery boot sweep UNCONDITIONAL. A fast
restart (deploy/OOM within the old 10-min window of the last step) left a run
stuck `running` forever, and the one-active-run gate then 409'd every future
turn in that chat. On a fresh single-process boot any pending|running run is
definitionally hung, so onModuleInit now settles ALL of them to `aborted` with
no staleness window. AiChatRunRepo.sweepRunning takes an optional { staleMs }
window, kept ONLY for the future phase-2 multi-instance timer sweep (the boot
path passes no window). Repo + service tests assert a fresh `running` run
(updatedAt = now) is settled, not skipped.
F2 (DECISION A): treat phase-1 autonomousRuns as SINGLE-INSTANCE-ONLY. Stop and
its AbortController are process-local, so cross-instance Stop is unreliable
(phase 2). AiChatRunService now logs a startup WARNING when a horizontally-scaled
deployment is detected — via EnvironmentService.isCloud() (CLOUD=true), the only
horizontal-scaling signal this codebase has (the socket.io Redis adapter is
always wired since REDIS_URL is mandatory, so it is not a discriminator). The
constraint is documented in AGENTS.md.

CRITICAL: any failure between a successful beginRun and streamText's terminal
callbacks taking ownership (the bare awaits: user-message insert, history load,
convertToModelMessages, settings resolve; the buildSystemPrompt/forUser block;
and synchronous streamText wiring) left ai_chat_runs stuck 'running' forever
(sweepRunning only runs at startup), which then 409'd every future turn in the
chat and made the observer tab poll forever. Wrap the body of stream() after
beginRun in a safety-net try/catch that settles the run to 'error' (via
onSettled) before rethrowing, and make finalizeRun idempotent (active.delete is
the once-guard) so a settle here and a settle from a streamText callback collapse
to a single terminal write.
Also from review comment 2519:
- correct three client comments that falsely claimed /ai-chat/run is "flag-gated
server-side and would 403" — it is owner-gated only; with the feature off the
chat simply has no runs so the endpoint returns { run: null }
(ai-chat-window.tsx, ai-chat-service.ts, ai-chat-query.ts).
- remove the dead UpdatableAiChatRun type (zero usages; the repo update uses an
inline Partial<...>).
- add controller specs for POST /ai-chat/run and /ai-chat/stop (owner-gating,
run:null when no run, run+message, stop by runId and by chatId).
- add tests: an exception after beginRun settles the run to 'error' and drops the
in-memory entry (next turn is not 409'd); finalizeRun is idempotent.

Reopening a chat whose agent run is still going showed a frozen snapshot
from the moment it was opened. Add a passive-observer reconnect-poll path:
when this tab did NOT start the run locally, poll POST /ai-chat/run every
2s while the run is pending/running and merge its incrementally-persisted
assistant message into the thread, so new steps/tool-calls and the growing
text appear live. Polling stops on terminal status (refetchInterval keyed
on run.status, mirroring the reindex polling); a final messages invalidate
shows the persisted end state.
Observer-vs-streamer detection: ChatThread reports its local useChat
streaming status up; the window only polls/merges while NOT locally
streaming (the streamer's SSE owns the view — no double-render). Gated by
settings.ai.autonomousRuns; the query is disabled when the feature is off
so the flag-gated endpoint is never hit, and a failed fetch can't loop
(retry:false -> refetchInterval(undefined)=false).
Pure decisions (poll interval, observe gate, message merge) extracted to
run-polling.ts and unit-tested; added query enable-gating and ChatThread
observer-merge tests. Client-only change — the reconnect endpoint already
returns the run plus the assistant message with its metadata.parts.

The "one active run per chat" guard was bypassable under a race. Two
simultaneous POST /ai-chat/stream on the same chat both passed the
controller's pre-hijack 409 check (a check-then-act TOCTOU), then the
loser's INSERT into ai_chat_runs hit the partial unique index
(ai_chat_runs_one_active_per_chat, 23505). That error was SWALLOWED, so
the second turn streamed UNTRACKED: no runId, not targetable by /stop,
and (autonomousRuns on) onClose won't abort it -> an orphan unstoppable
run that also spends provider tokens.
Make the unique-index INSERT the authoritative gate:
- AiChatRunService.beginRun: when the run-row INSERT fails with a 23505 on
ONE_ACTIVE_RUN_PER_CHAT_INDEX (via isUniqueViolation/violatedConstraint),
no longer swallow it -> throw a distinct RunAlreadyActiveError. Any other
error (incl. a 23505 on a different constraint) propagates unchanged.
- AiChatService.stream: when begin throws RunAlreadyActiveError, reject the
turn with a 409 ConflictException (code A_RUN_ALREADY_ACTIVE) BEFORE any
AI/provider call -> no tokens spent, no untracked turn. Other begin
failures keep the legacy best-effort fallback (stream socket-bound).
- ai-chat.controller: post-hijack catch honors an HttpException's real
status/body (clean 409) instead of a blanket 500, since the race 409 is
raised before a byte is written. Pre-check 409 now carries the same code.
The controller's cheap pre-check stays as a fast-path for the common
sequential double-submit; the INSERT violation is the race-safe backstop.
Tests: ai-chat-run.service.spec proves beginRun throws RunAlreadyActiveError
on the active-index 23505 (and only that constraint), leaks no controller,
and an integration-style two-concurrent-begins test where exactly one wins;
new ai-chat.service.run-race.spec proves stream rejects with a 409
ConflictException BEFORE any streamText/generateText and never persists an
untracked turn. The latter fails without the fix.

Make an agent turn a first-class, server-side RUN that keeps executing and
persisting its steps after the browser window closes, and that a later client
can reconnect to — the core invariant of #184. Phase 1 only; the full proposal
(cross-process BullMQ runner, resumable live-tail transport, autonomy triggers,
budgets, history compaction) is explicitly deferred.
What lands:
- `ai_chat_runs` lifecycle table + repo: the run as a persistent object
(status pending->running->succeeded|failed|aborted, trigger, createdBy,
assistantMessageId projection link, error, step_count, timings). A partial
unique index enforces ONE ACTIVE run per chat; a startup sweep recovers
dangling runs (mirrors #183's sweepStreaming).
- AiChatRunService: owns the run lifecycle + an in-memory abort registry. The
abort is governed by the RUN (an explicit user stop), NOT the HTTP socket —
so a browser disconnect no longer ends the turn. Reuses #183's socket-
independent durable write path (consumeStream + flushAssistant) unchanged.
- Controller, behind `settings.ai.autonomousRuns`: /stream wraps the turn in a
run and does NOT abort on disconnect (logs only); a clean 409 rejects a
concurrent run on the same chat; new POST /ai-chat/stop (explicit stop) and
POST /ai-chat/run (reconnect -> latest persisted run + its projection). The
runId is surfaced on the streamed start metadata. Flag OFF = byte-for-byte
legacy behavior.
Tests: AiChatRunService unit spec (lifecycle, disconnect != stop, explicit
stop aborts the signal, best-effort sweeps); ai_chat_runs integration spec
(one-active-run index, detached persist+reconnect with no subscriber, explicit
stop, stale-run sweep). Server tsc + build clean; touched jest green.

Rework the fact-checker editorial role prompt so it stops commenting on
correct facts and only flags problems (errors, doubtful, unverifiable).
- Add the directive "don't write/comment that a fact is right or confirmed:
your job is to find errors, not confirm facts" to both RU and EN bundles.
- Remove the [Подтверждено]/[Verified] verdict; reframe the verdict list as
"for problem claims only".
- Reword the role description (no longer "confirms") and the
comment-on-every-claim rule to "problem claims only".
- Bump fact-checker role version 2 -> 3 and refresh the content-hash lock.

Review #6 (approve-with-comments) follow-ups:
1. canonicalize step 7 now strips bare footnoteDefinitions at ANY depth
(stripFootnoteDefinitionsDeep), not just footnotesList, in BOTH copies. A
definition hand-authored outside a list (e.g. nested in a callout via a
raw-JSON write path) was left in place while a copy was also added to the
rebuilt list -> duplicate, idempotent, self-perpetuating. Runs only in the
rebuild path (after the lists are stripped); the fast-path / placement-keep
branch is untouched. Added a shared-corpus case (bare def nested in a callout)
to pin it in both mirrors.
2. markdown-clipboard: removed the dead top-level footnoteReference check in
canonicalizePastedFootnotes (an inline atom is never a top-level slice child;
only the descendants scan can find it).
Test coverage:
4. New MCP binding tests (full-doc-write-canonicalize.test.mjs): update_page_json
and copy_page_content canonicalize the persisted full doc, asserted via a new
`replacePage` seam (symmetric to the existing `mutatePage` seam) so no live
collab socket is needed. Routed both writers through the seam.
5. New server spec (file-import-task.service.footnote-canonicalize.spec.ts): the
zip-import path (processGenericImport) canonicalizes footnotes — real
markdown->HTML->JSON via a real ImportService over a temp-dir .md file, DB trx
stubbed to capture the persisted page content. FileImportTaskService had no
spec before.

Must-fix:
- insertInlineFootnote could glue a footnoteReference inside an EXISTING
definition (nested footnotesList, or a bare footnoteDefinition with no list
wrapper), which canonicalize then dropped as an orphan — silently losing the
definition's prose. Now: (a) the body/notes boundary is computed from the first
top-level block that IS or CONTAINS (recursively) a footnotesList/
footnoteDefinition, not just a top-level list; and (b) the insertNodesAfterAnchor
core skips footnotesList/footnoteDefinition subtrees entirely (skipSubtreeTypes),
so an anchor whose only match is inside a definition -> inserted:false (clean
abort, no write). Added tests: nested-definition, bare-definition, and
body-before-nested-list-still-inserts.
- editor-ext footnote-canonicalize header listed `markdownToProseMirror` among the
canonicalizing MCP paths; it is the NON-canonicalizing primitive. Replaced with
`markdownToProseMirrorCanonical` (+ note that the plain primitive is for comment
bodies) and added copy_page_content.
- Client paste: canonicalizePastedFootnotes now skips a definitions-ONLY paste
(no footnoteReference anywhere) — canonicalizing it would strip the
reference-less list and yield an EMPTY paste. Added a test.
Suggestions:
- docmost_transform now runs validateDocStructure/validateDocUrls on the RAW
transform output BEFORE canonicalizeFootnotes (mirrors updatePageJson), so a
too-deep doc gives the intended max-depth error instead of a stack overflow.
- docmost_transform tool description now states the RESULT is footnote-canonical
(dryRun diff may show tidy-ups; idempotent after first run).
- insertFootnote: dropped the dead `result ? … : undefined` ternaries and the
`as any` casts (result is always set by the time we return; the not-found path
throws and aborts mutatePage). `const r = result!;`.
Tests / architecture:
- Added a LIVE-plugin golden case: the real footnoteSyncPlugin leaves a list with
non-empty content after it in place, and canonicalize agrees (placement parity
is now a driven property, not a hand-set expected).
- Added generateFootnoteId uuidv7 shape + uniqueness test.
- Item 9: added the ENFORCEMENT-RULE comments at the server parseProsemirrorContent
and the MCP canonicalizer header (any NEW full-doc persist path MUST canonicalize;
fragments/append/prepend and comment bodies MUST NOT). Kept per-call-site over a
brittle grep CI test (the replace-vs-fragment + comment-vs-page nuance makes a
single wrapper unsafe).

Must-fix (REAL DATA LOSS):
- markdownToProseMirror is reused for COMMENT bodies (createComment/updateComment).
It unconditionally canonicalized, so a comment carrying a standalone footnote
definition ([^1]: text with no matching reference) had its whole footnotesList
stripped (referenceIds.length===0 -> stripFootnotesListsDeep) — the text
vanished. Fix: markdownToProseMirror no longer canonicalizes (content-preserving
primitive); a new markdownToProseMirrorCanonical wraps it for the PAGE write
paths (markdown import via importPageMarkdown, update_page markdown via
updatePageContentRealtime). Comment callers keep the non-canonicalizing
primitive. Updated the now-false header comment and added create/update-comment
inline notes. Added collaboration tests: comment path PRESERVES a reference-less
definition; page path still drops it AND still reorders real footnotes. Updated
the page-import canonicalization test to use the canonical variant.
Suggestions / architecture:
- #2: collapsed transforms.footnoteDefinition onto the shared
makeFootnoteDefinition factory (adds only the inner paragraph block id); kept
the dependency direction transforms -> footnote-authoring (no circular import,
mirror stays pure).
- #3: confirmed docmost_transform auto-canonicalization is documented (inline
comment, tool description, CHANGELOG) — no code change.
- #4: copyPageContent is a FULL-document write (replacePageContent of a
type:"doc"); added a defensive canonicalizeFootnotes pass (no-op on
already-canonical source).
- CHANGELOG entry refined to list the FULL-document write paths (incl.
copy_page_content) and to state canonicalization is NOT applied to comment
bodies.

Approve-with-comments follow-ups (no blockers):
- callout: unify the GitHub-callout feature ticket on #192 (the callout-paste
feature the CHANGELOG already tracks); #218 is the public-share security work.
Fixed the code comment and test reference.
- export/utils.spec: pin current behavior of a leading-dot name (".gitignore" ->
"") — same bug class as #204 but unreachable via the sole caller, so document
not change.
- share.types: narrow ISharedPage to the actual /shares/page-info allowlist
(page -> Pick of id/slugId/title/icon/content; trimmed share; dropped the
spurious `extends IShare`). Verified all three consumers (shared-page,
link-view, mention-view) read only allowlist fields.
- editor-ext: extract shared CALLOUT_TYPES / normalizeCalloutType /
renderCalloutHtml into callout-common.marked.ts; both tokenizers
(`:::type` and `> [!type]`) now share the renderer + type dict while staying
separate. Eliminates the byte-identical renderer + duplicated type list.
- share.service: extract named predicate shareIdGrantsAccess(requestedShareId,
resolvedShare) for the id-or-key fast path (naming only, no control-flow
change); kept narrower than resolveReadableSharePage's id-only gate.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Must-fix:
- REAL BUG: insertInlineFootnote could splice a footnoteReference (inline atom)
into a codeBlock or an existing footnoteDefinition, persisting a schema-invalid
doc (insert_footnote skips validateDocStructure). Now the search is bounded to
the BODY (before the first footnotesList) and the insertNodesAfterAnchor core
refuses textblocks that can't hold the atom (codeBlock); when the only match is
in such a place the insert returns inserted:false and the write aborts cleanly.
Reachable via docmost_transform too. Added codeBlock / definition / fall-through
tests.
- Fixed the deepEqualJson doc comment in both copies: arrays are order-SENSITIVE
(correctness depends on it), only object keys are order-insensitive.
- README.ru.md MCP tool count 38 -> 39 (lines 36/47/63), matching README.md/AGENTS.
- CHANGELOG [Unreleased] Added entry for insert_footnote + server-side footnote
canonicalization on non-editor write paths (#228).
Suggestions:
- canonicalize step 5/7 now strips footnotesList at ANY depth (both copies), so a
schema-valid list nested in a callout/blockquote can't leave duplicate defs.
- Exclude the test-only footnote-corpus.ts fixture from the editor-ext build
(tsconfig), so it no longer ships in dist/.
- Removed the duplicate manual canonicalize cases from the MCP unit test (the
shared corpus covers them via full deepEqual); kept idempotence + immutability.
- insertInlineFootnote dedup key now keys off the inline array directly
(footnoteContentKey({ content: inline })) instead of a throwaway node.
Tests / architecture:
- New client-wrapper test (#9): overrides a small mutatePage seam to assert the
not-found path throws and persists NOTHING, and the success path shapes
footnoteId/reused/message/verify and writes the right content. Fixed the
misleading comment in footnote-write.test.mjs.
- B: cross-copy corpus parity guard test (loads both corpora, asserts deep-equal)
so a typo in one copy can't pass both suites green.
- A: declined — the full-vs-fragment decision lives at the call site, so a
prepareDocForPersist wrapper would be a bare alias for canonicalizeFootnotes;
kept the existing per-call-site comments instead.

Approve-with-comments follow-ups:
- breadcrumb: fix the reverse regression where navigating A->B to a page absent
from the lazily-built tree (before its ancestors load) left the previous
page's clickable chain on screen. New pure computeBreadcrumbState clears a
stale chain that doesn't end at the current page, while keeping one that does
(no blank flash for an already-resolved page); unit-tested for the
navigated-to-absent-page case.
- share.service: getShareAncestorPage no longer swallows DB errors silently —
now a live public-share path (isPageReachableThroughShare), so a transient
error is logged with ancestor/child ids and still fails closed (caller 404s)
instead of becoming a traceless misleading "not found".
- i18n: register the new "Connecting… (read-only)" key (U+2026 ellipsis) in
en-US (source of truth) and ru-RU (Подключение… (только чтение)).
- share.service: correct the FUTURE note — 3 callers pass no shareId
(share-alias.controller/.service, share-seo.controller); the two ai-chat
callers already pass a real shareId.
- CHANGELOG: add Unreleased Changed/Fixed/Security entries for #216 opt-in
sub-pages default, #218 trimmed page-info payload + forged-shareId 404, #204
export internal-link name, #206/#218 breadcrumb, #192 callout paste, #218
editor pre-sync read-only gate.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Must-fix:
- Move canonicalizeFootnotes OUT of parseProsemirrorContent. It now runs only
on FULL writes (createPage, updatePageContent operation==='replace'), never on
an append/prepend fragment (a fragment would lose definition-only footnotes or
synthesize a bogus empty list). Add a server binding spec.
- Match the live plugin's list PLACEMENT: a single already-canonical
footnotesList is left exactly where it sits (the plugin never repositions a
sole correct list), so the first write no longer reorders content that follows
the list. Applied to BOTH the editor-ext copy and the MCP mirror; pinned by a
shared golden corpus case with content after the list.
- Fix MCP tool count 38 -> 39 (README x3, AGENTS.md) and the transformJs param
help (add canonicalizeFootnotes/insertInlineFootnote).
Simplifications:
- Remove the dead duplicate re-id mechanism (deriveFootnoteId/suffix/occurrence)
from the PURE canonicalizer in both copies — references are never renamed, so
the derived ids were never requested; first-wins-drop is the real behaviour.
This also makes the editor-ext footnote-util note about "no cross-package copy"
true again.
- Remove the sentinel round-trip in insertInlineFootnote: a generalized
insertNodesAfterAnchor core inserts the footnoteReference node directly.
- Drop the redundant per-definition deep clone in step 4 (shallow id-normalizing
copy; out is already deep-cloned).
Docs / architecture:
- Correct the editor-ext copy's "It exists because…" header to its real
consumers (server import, page.service create/update, client paste).
- Note markdownToProseMirror reuse for create/update comment in collaboration.ts.
- A: shared golden JSON corpus exercised by BOTH the editor-ext copy and the MCP
mirror (footnote-corpus.ts / .mjs) so "the two copies behave identically" is
checkable.
- C: split the MCP canonicalizer into a pure mirror + footnote-authoring.ts.
- B: import services persist via a different path, so left one-line consolidation
comments at the call sites rather than folding (does not fall out cleanly).
Tests: insertFootnote wrapper guards + docmost_transform dryRun auto-canonicalize
(MCP mock), page.service create/update + append/prepend binding (server jest),
shared corpus incl. nested-container reference.

Review follow-ups for the combined QA-UI fixes (#216/#206/#204/#218/#192):
- export/utils: correct the misleading getInternalLinkPageName comment — a
bare `v1.2` loses its last dot-segment (`v1`); dots survive only in
multi-segment names like `v1.2.md` -> `v1.2`.
- share: extract toPublicSharePayload(page, share): PublicSharePayload, an
explicit allowlist type+mapper replacing the inline literal in the
/shares/page-info anonymous path (#218). Add share.controller.spec.ts that
stubs getSharedPage returning internal fields and asserts the response key
set EXACTLY equals the whitelist (page + share), so any `...shareData`
regression or new leaking field fails. Also key-tests the extracted mapper.
- breadcrumb: extract pure resolveBreadcrumbNodes(treeData, ancestors, pageId)
(tree-hit -> tree; tree-miss -> map ancestors via canonical pageToTreeNode,
dropping the as-any casts; else null) and unit-test all three branches.
- share-modal: RTL test asserting enabling a share calls mutateAsync with
includeSubPages: false (#216 security default).
- share.service: one-line note at getSharedPage on the deferred consolidation
of the ancestor-aware match into resolveReadableSharePage.

The footnote canonicalizer was wired into the MCP and editor-ext write paths
but NOT into the server's user-facing markdown/HTML import paths, so importing
or pasting markdown with out-of-order, reused, or orphan footnotes did not
canonicalize -- the exact trigger bug #228 fixes was still reproduced on
import. markdownToHtml -> htmlToJson builds ProseMirror JSON directly and never
runs the editor's footnoteSyncPlugin, and that plugin does not reorder an
existing list, so the stored footnotes kept the source's physical definition
order, retained orphans, and did not collapse reused references.
Wire canonicalizeFootnotes (already exported from @docmost/editor-ext) into
every server markdown/HTML -> page-JSON seam, before persisting:
- ImportService.importPage (REST single-file .md/.html import)
- FileImportTaskService (zip import worker)
- PageService.parseProsemirrorContent (API createPage / updatePageContent)
Also hook the client markdown paste: handlePaste applies a manual transaction
(returns true), bypassing transformPasted/footnoteSyncPlugin, so a pasted
out-of-order markdown footnote block would persist out of order.
canonicalizePastedFootnotes reorders a self-contained pasted block (one that
carries its own footnotesList) to reference order, deduped and orphan-free; it
is deliberately scoped to whole-block pastes so a reference-only paste that
reuses a footnote already defined in the target doc is left untouched.
canonicalizeFootnotes is pure, idempotent and shape-safe (a doc with no
footnotes is unchanged), so it is safe on every write path.
Residual: when a pasted block merges into a doc that already has footnotes,
ordering relative to the pre-existing footnotes is still governed by the live
sync plugin (which does not reorder across the boundary).

Make footnotes author-inline: the agent/tool inserts a footnote at its point
of use (anchor + text) and the numbering plus the bottom list are DERIVED
deterministically server-side. The agent has no access to footnotesList and
cannot desync — out-of-order lists, orphan definitions, and raw trailing
[^id] blocks become structurally impossible.
editor-ext:
- canonicalizeFootnotes(docJSON) -> docJSON: a pure, EditorView-free port of
footnoteSyncPlugin's end-state. Distinct reference ids in document order are
the source of truth; exactly one trailing footnotesList holds one definition
per referenced id in reference order (reusing the existing node or
synthesizing an empty one); orphans dropped; duplicate definitions resolved
deterministically (first wins, never lost); idempotent.
- Unit tests + a golden parity suite: on every editor-reachable steady state
the live footnoteSyncPlugin's JSON is a canonicalize no-op (byte-for-byte
parity), and the canonicalizer additionally repairs the out-of-order list a
non-editor write produces.
mcp:
- footnote-canonicalize.ts: behavioural mirror of the editor-ext canonicalizer
(the MCP package is intentionally decoupled from the editor barrel, like
footnote-lex/docmost-schema), plus footnoteContentKey for content dedup.
- Auto-canonicalize on EVERY write path: markdownToProseMirror (fixes import
ordering), update_page_json, and after every docmost_transform. Idempotent,
so it is a no-op when footnotes are already canonical.
- insert_footnote tool + insertInlineFootnote: anchor + markdown text -> a
mark-safe footnoteReference and a content-dedup'd definition; the list and
numbering are derived. Same-content footnotes reuse one number/definition.
- canonicalizeFootnotes + insertInlineFootnote exposed as docmost_transform
sandbox helpers.
Tests: editor-ext 157 green; MCP 325 green; server + client tsc clean.

Additive test coverage across server, editor-ext, client and mcp.
#192 — AiChatService.stream integration (Section 3, against real Postgres):
- new apps/server/test/integration/ai-chat-stream.int-spec.ts drives the real
streamText through a seeded ai/test MockLanguageModelV3 and a real Node
ServerResponse, covering: onError persists an assistant error record
(status 'error' + partial answer + provider cause in metadata); external MCP
client closed exactly once on BOTH onFinish and onError; anti-tamper —
history is rebuilt from the DB transcript, not from body.messages.
#206 — red-team findings (most already fixed+tested in #212):
- mdrt-2 (UNFIXED, data loss): turndown.dataloss.test.ts documents that
pageBreak / transclusionReference / mention are silently dropped on Markdown
export (characterization + it.fails for the desired survive-export contract).
- persist-6 (UNFIXED, data loss): persistence-store.spec.ts adds an it.failing
documenting that a momentarily-empty live doc overwrites non-empty content
(left unfixed — a store-side empty-guard is a behaviour change).
#204 — test-strategy plan, highest-priority subset:
- Phase 1: mcp-clients.lease.spec.ts covers the external MCP client
lease/refcount/eviction lifecycle (leak / premature-close / double-close).
- Phase 2 data-integrity pure functions: editor-ext table-utils
(transpose/moveRow/convert round-trip) and math tokenizer false-positive
guard; client emoji-menu (+ it.fails for the unguarded localStorage
JSON.parse bug), sort-cells, normalizeTableColumnWidths; mcp htmlEmbed/
pageBreak markdown data-loss + footnote-diff; server export
getInternalLinkPageName extensionless-path bug — FIXED (small/clear) + tested.

Public sharing (#218):
- Bind public-share content to the requested shareId. getSharedPage now
enforces dto.shareId (forwarded from /share/:shareId/p/:slug): the page must
be reachable THROUGH that exact share (its own share, or an includeSubPages
ancestor that contains it). A forged/mismatched shareId 404s instead of
rendering off the slug alone and no longer leaks the real canonical key via
redirect. A request with no shareId keeps the legacy slug-capability path.
- Trim /shares/page-info: drop internal metadata (creatorId, spaceId,
workspaceId, contributorIds, lastUpdated*, parent/position, lock/template
flags, timestamps) from the anonymous payload.
- Default share-to-web includeSubPages to false (opt-in), so enabling a share
no longer silently exposes the whole sub-tree (#216).
Editor (#218):
- Harden the new-page pre-sync window: the body editor is kept read-only until
the collab provider is Connected and synced, so early keystrokes can't land
only in local ProseMirror and then be clobbered by the server's empty doc.
- Surface a "Connecting… (read-only)" affordance during the static phase so
input isn't silently swallowed.
Other:
- Breadcrumb: resolve from the page's own ancestor data (/pages/breadcrumbs)
instead of waiting for the lazily-built sidebar tree, so deep pages don't
render a blank breadcrumb for seconds.
- Pasting GitHub `> [!type]` callouts now converts to a callout node instead of
a literal blockquote (new marked extension wired into markdownToHtml).
Tests: editor-sync-state gate (client), getSharedPage share-binding (server),
github-callout markdown conversion (editor-ext).

The proofreader role content was changed (STYLE SHEET block removed) without
bumping its catalog version, so clients never saw an update. Bump proofreader
2 -> 3, and add a content-hash guard so this can't happen silently again.
- index.json: proofreader version 2 -> 3
- scripts/check.mjs: new content-hash guard. A scripts/content-hashes.json lock
maps slug -> { version, hash } (sha256 over emoji/autoStart/name/description/
instructions/launchMessage across all languages). check.mjs now fails when a
role's content changed without bumping its version; the new --update-hashes
(alias --fix) refreshes the lock but refuses to write when a bump is missing.
- check.mjs: also require every index.json role to carry a finite numeric
version (matches the server's catalog validation), with defense-in-depth so a
missing version can't bypass the bump guard.
- scripts/content-hashes.json: new lock artifact (not part of the served catalog).
- README.md: document the guard, the lockfile, --update-hashes, and the
prune-then-readd limitation.

The agent-roles catalog source is no longer hardcoded in app code and no longer
supports a local filesystem directory. The provider fetches only from an
http(s):// base URL read at runtime from AI_AGENT_ROLES_CATALOG_URL; an empty or
non-http value yields a 502 (catalog unavailable). The image ships a per-branch
default for that URL (set in CI), still overridable at runtime via the env var.
- provider: drop readLocal + node:fs/node:path; readRelative requires http(s)
and 502s otherwise; remote fetch/streaming-cap/SSRF guards unchanged.
- environment.service: keep AI_AGENT_ROLES_CATALOG_URL (default ''); comment
reflects the per-branch build-time default that is runtime-overridable.
- Dockerfile: add ARG+ENV AI_AGENT_ROLES_CATALOG_URL in the installer stage as
the image default.
- CI: develop.yml builds with the develop raw URL; release.yml defines the main
raw URL once in workflow env and references it from both build steps.
- tests: replace local-fixture tests with remote-mock happy/malformed bundle
tests and a non-http => 502 case; path-traversal block uses an https source.
- docs: update .env.example, CHANGELOG (#222), agent-roles-catalog/README.

Address PR #227 re-review (comment 2193).
- Stability: `updatePageId`/`updateAlias` now `executeTakeFirstOrThrow`, so a row
reaped by a concurrent `removeAlias` between the read and the UPDATE (READ
COMMITTED) raises `NoResultError` instead of returning `undefined`. The service
maps that to a retryable `ConflictException` (`ALIAS_PAGE_RACE`) rather than a
200-without-alias (swap) or a generic 400 from `undefined.id` (rename). Tests
cover both branches.
- Simplification: drop the redundant secondary "unexpected unique index" warn and
the now-unused `UNIQUE_ALIAS_INDEX` const (the constraint name is already logged
unconditionally; both index branches still distinguish "Alias already taken" vs
ALIAS_PAGE_RACE).
- Architecture: extract `isUniqueViolation`/`violatedConstraint` into
database/utils.ts; adopt them in the share-alias service and favorite.repo
(the bare `23505` check). ai-agent-roles (#222) is on a separate unmerged branch
and should adopt them after #227 merges (noted at the helpers). Helper unit test
added.

The share modal flagged a custom address already owned by another page with a
red "This address is already in use" error driven by the availability probe.
That reads as terminal even though Save actually triggers the server's
409 `ALIAS_REASSIGN_REQUIRED` and opens the "Move custom address?" confirm
modal that retargets the address to the current page — so the reassign path was
hidden behind what looked like a hard stop.
Replace the red error with an informational description hint ("This address is
in use. Saving will move it to this page.") and keep Save enabled, so the
existing confirm-reassign flow is discoverable. Renaming to a FREE name was
already correct (the probe returns available -> no error -> server renames the
single row in place); this only changes the taken-name presentation.
Verified end-to-end in a real browser against a live stand on this branch:
- A (free rename `test`->`test2`): 200, same alias row renamed in place, link
becomes `/l/test2`, no error, exactly one DB row for the page.
- B (`test2` owned by another page): hint shown (no dead-end error), Save ->
409 ALIAS_REASSIGN_REQUIRED -> "Move custom address?" modal -> confirm -> 200,
the single row retargets, one row each.
- C (same-name re-save): Save disabled (no-op); first-time set inserts.
Add a client component test covering both branches (taken name -> hint not
error + Save enabled; 409 -> reassign modal -> confirm sends confirmReassign).

Addresses review on PR #227.
- setAlias confirmed-reassign branch: DELETE the target page's existing
alias row(s) BEFORE retargeting `byName` onto the page, instead of after.
The new partial unique index `(workspace_id, page_id)` is non-deferrable
and checked at each statement, so retargeting first momentarily left two
rows for the page -> immediate 23505 -> rolled-back tx surfaced as a
misleading "Alias already taken" (regressing a previously-working swap onto
a page that already had its own alias). The reordered branch needs no
trailing self-heal. JSDoc updated to describe the real ordering.
- catch block: the postgres@3.x driver exposes the violated index as
`err.constraint_name` (with `.constraint` as a fallback). Map
`share_aliases_workspace_id_alias_unique` -> "Alias already taken" and the
new `share_aliases_workspace_id_page_id_unique` -> a distinct ALIAS_PAGE_RACE
outcome (a concurrent same-page write, not a name clash). Always log the
constraint name on any 23505 so the race is diagnosable.
- migration 20260627T120000: document that the dedup DELETE is intended,
irreversible data loss (old duplicate `/l/<old>` links start 404ing after
upgrade; `down()` cannot restore the rows). Same note added to CHANGELOG
[Unreleased] Fixed.
Tests:
- integration: confirmed reassign onto a page that ALREADY has its own alias
(RED before the reorder); migration up() dedup scoping across pages and a
second workspace; mid-transaction error -> BadRequest with clean rollback.
- unit: constraint_name distinguishing (alias index, page_id index, fallback
`.constraint`, no-info default) and non-unique error -> BadRequest; retarget
test now asserts delete-before-update order.

Editing an existing share alias (e.g. slug `te` -> `ted`) failed to update
the displayed `/l/<alias>` link: `setAlias()` looked the requested slug up by
name and, if free, INSERTed a brand-new row, leaving the page with multiple
alias rows. The modal then read via `findByPageId().executeTakeFirst()` with no
`ORDER BY`, so Postgres returned an arbitrary (in practice the oldest, stale)
row. Every edit also spawned an orphan row that kept a live `/l/<old>` link
forever. Regression of #205.
Enforce the invariant "a page has EXACTLY ONE custom address":
- `setAlias()` now resolves the page's current alias row and RENAMES it in
place when the requested name is free (insert only when the page has none),
keeps the same-name no-op and the cross-page 409 `ALIAS_REASSIGN_REQUIRED`
+ confirmed-retarget flow, and after any successful write DELETEs all other
alias rows for the page (self-heal). Runs in one transaction so the page is
never transiently empty or duplicated.
- repo: add `updateAlias` (rename) and `deleteOthersForPage`; make
`findByPageId` deterministic with `ORDER BY created_at DESC, id DESC`.
- migration: dedup existing rows (keep newest per page) + a PARTIAL unique
index `(workspace_id, page_id) WHERE page_id IS NOT NULL` so dangling
aliases still coexist while live ones are one-per-page.

ITEM 1: cover useImportAiRolesFromCatalogMutation onSuccess notifications.
Add import-from-catalog-message.test.tsx (twin of update-from-catalog-message)
asserting the always-shown summary (errors:[]) and the additional red
"Failed to import N role(s)" notification when result.errors is non-empty.
ITEM 2: pass redirect:'error' to the remote catalog fetch in fetchRemote so a
compromised-but-trusted upstream cannot 3xx the fetch into the internal network
(redirect-SSRF). Add provider specs asserting the option is passed and that a
redirect rejection maps to BadGatewayException.

MUST-FIX
- isSourceUniqueViolation read the wrong error field: kysely-postgres-js
(postgres@3.4.8) puts the violated constraint on `constraint_name`, not
node-postgres' `.constraint`, so a concurrent same-slug+language import's
23505 was never recognized as a source-collision and surfaced a false
"name already exists" error. Now read `constraint_name` (with `.constraint`
as a fallback for other drivers). Fix the faked test fixture (it built the
error with the same wrong `.constraint` field, masking the bug): it now
uses `constraint_name`, so the test genuinely exercises the skip path and
FAILS against the unfixed code.
- Extract the catalog modal's role-state computation into a pure
`catalogRoleInstallState(role, workspaceRoles, language)` helper (mirrors
role-launch.ts) and cover it with vitest: import / installed / update /
same-slug-different-language.
SUGGESTIONS
- Restore IAiRoleUpdateFromCatalogResult as a discriminated union mirroring
the server; narrow the consumer via `"reason" in result` (the boolean
discriminant does not narrow under strictNullChecks:false).
- README: add a "How it's served" section documenting AI_AGENT_ROLES_CATALOG_URL
(remote http(s) base / local path / empty => in-repo folder).
- check.mjs: drop the redundant `const key = slug` alias.
- Cover the reason->message mapping in useUpdateAiRoleFromCatalogMutation
(4 branches) via renderHook with a mocked service.
- Cover importFromCatalog "bundle not in index" => BadGateway.
- Cover updateFromCatalog "slug in index but missing in bundle file" =>
not-in-catalog.
ARCHITECTURE
- Extract the shared catalog read prefix: a private `loadBundleById`
(fetchIndex -> meta -> fetchBundle -> versionMap) reused by getCatalogBundle
and importFromCatalog, and a `catalogRoleContentFields` mapper shared by the
import insert and update patch. The three orchestrations and their distinct
write paths stay separate.

Address review comment 2159 on the temporary-notes UI work.
Tests:
- tree-model: cover handleCreate's race-guard temporaryExpiresAt patch — (a)
server node inserted WITHOUT a deadline + create response carries one => node
gains the deadline; (b) node already has a deadline => not overwritten, prev
returned by reference.
- ws-tree.service.spec: broadcastPageCreated now asserts the deadline is carried
when present and pinned to null (`?? null`) when absent.
- page-embed-query (new spec): syncTemporaryExpiresInCache patches the in-tree
node's temporaryExpiresAt, and leaves the atom value at the same reference when
the id is absent from the loaded tree (no write).
Refactor (closes the drift bug-class at the root):
- Client: extract one canonical pageToTreeNode(page, overrides) mapper in
tree/utils and route buildTree, handleCreate's optimistic insert, the restore
mutation and the duplicate handler through it. Restore stays permanent (server
nulls temporaryExpiresAt) and duplicate stays permanent (server arms no timer)
— both now reflect the server without a reload, where before they dropped the
field entirely.
- Server: extract one toTreeNodeSnapshot(page) helper called by both the
PAGE_CREATED event enrichment (page.repo) and the addTreeNode broadcast
(ws-tree.service), so the optional temporaryExpiresAt can't drift between the
two literals.

Issue 1 — the sidebar tree's temporary-note clock marker did not appear/
disappear until a page reload when a note's temporary state changed.
- Make/unmake permanent from the page header menu and the in-page banner went
through syncTemporaryExpiresInCache(), which patched the page query cache but
never touched treeDataAtom, so the sidebar node kept its stale
temporaryExpiresAt. Patch the tree node there too (via jotai's default store),
so the marker updates without a reload.
- Creating a note as temporary showed no marker until reload: the create flow's
cache write (invalidateOnCreatePage) omitted temporaryExpiresAt, so the tree
rebuild (buildTree -> mergeRootTrees) overwrote the optimistic/socket node's
marker with undefined. Carry temporaryExpiresAt in that cached entry.
- Thread temporaryExpiresAt through the server addTreeNode broadcast (PAGE_CREATED
snapshot -> TreeNodeSnapshot -> broadcastPageCreated) so OTHER clients watching
the space also render the marker immediately, and harden handleCreate's
idempotency guard to patch the deadline if the broadcast won the insert race.
Issue 2 — the home and space-overview "New note" / "New temporary note" buttons
sat side-by-side and the temporary label clipped on narrow mobile widths. Lay
them out full-width, stacked vertically, and tint the temporary button orange
(matching the clock marker + banner) while the regular one stays neutral gray.
Tests: extend tree-socket-reducers.test.ts (addTreeNode carries
temporaryExpiresAt). Verified live with Playwright: marker appears on create and
toggles both ways with no reload; mobile buttons are stacked, full-width,
unclipped, and differently colored.

Item 1 (concurrency-safe import): add a partial UNIQUE index on
(workspace_id, source->>'slug', source->>'language') WHERE source IS NOT NULL
AND deleted_at IS NULL, so two concurrent imports of the same bundle can no
longer create duplicate roles for one catalog slug+language. The in-memory
installedKeys snapshot cannot see a sibling request's writes; the index is the
backstop. importFromCatalog now catches the 23505 from THIS index (keyed off
the constraint name) and treats it as "already installed" -> skip, batch
continues. A 23505 from the name-uniqueness index keeps its existing friendly
per-role error behavior (distinguished by constraint name; an indeterminate
23505 falls back to that path, so no regression).
Item 2 (single source validator): strengthen parseSource into THE single form
validator for the source jsonb column -> returns a fully-valid RoleSource | null
(slug/language non-empty strings, version a number). The service's weaker
roleSource is removed and both layers share the RoleSource type (defined in the
db entity.types module both already import AiAgentRole from, so no import
cycle). normalizeRow / the read path now only ever yield a valid RoleSource or
null; a malformed stored source normalizes to null (tolerated by the service).
Tests: parseSource null for {} / {slug:123} / {slug:'a'} / empty-string keys /
string version, typed value for a full valid shape; service test that a
source-uniqueness 23505 is skipped (not errored) and the batch continues.
Verified the partial index rejects a duplicate source-not-null row but allows
two source-NULL rows, and the migration up/down run cleanly.

- CHANGELOG: document the importable multilingual agent-roles catalog under
[Unreleased] (browse/import/update, 4 new endpoints, source column, the new
AI_AGENT_ROLES_CATALOG_URL env var) (#222).
- Fix importFromCatalog docstring: a role is skipped only on source.slug AND
source.language; another language of the same slug still imports.
- Provider: map a timeout/abort (or any failure) during the response-BODY read
to a logged BadGatewayException, so a slow/dripping source yields a 502, not a
generic 500. Existing too-large BadGateway cases are rethrown as-is.
- Service: inject a Nest Logger and log the root cause (with workspaceId/
bundleId/slug) on a non-23505 insert error during import.
- Modal: hoist the duplicated i18n base-subtag into a single baseLang const.
- Tests: AbortError body-read -> BadGateway; null-body text() fallback (under
and over cap); invalid-JSON and malformed-index BadGateway; non-23505 import
error -> generic message + logged root cause.

- Rename catalog-source migration 20260626T120000 -> T150000 so it sorts
after develop's latest migration (T140000-page-temporary-notes); the old
timestamp predated ai-chat-message-status/share-aliases and tripped
Kysely's #ensureMigrationsInOrder, aborting server boot.
- Provider: inject a Nest Logger and log the real cause (incl. response
status) in the parseJson / readLocal / fetchRemote catch blocks, and
propagate a useful cause into the BadGatewayException message; add a
shortError helper (robust to jest's realm-shifted Error-likes).
- Provider: replace the manual Uint8Array assembly with
Buffer.concat(chunks).toString('utf8'); keep the streaming size cap.
- Controller spec: add admin-gate coverage for the 4 catalog routes
(catalog/catalogBundle/import/updateFromCatalog) - non-admin Forbidden +
service untouched, admin delegates with the right args.
- Service spec: add getCatalog/getCatalogBundle tests covering the
localized() three-tier fallback, the sorted language union, the
missing-bundle BadGateway, and the role-version default.
- Provider spec: add remote fetch-rejects and non-ok (503) error branches.
- Service: drop the dead Date.now() tail in freeName (now an explicit
unreachable throw) and extract a shared isUniqueViolation() predicate.

Admins can browse a curated catalog of agent roles, import roles/bundles
into a workspace, and update an imported role when the catalog ships a
newer version.
Catalog: a set of JSON files (index.json manifest + bundles/<id>/<lang>.json)
served from a local folder (dev) or a remote http(s) base URL via
AI_AGENT_ROLES_CATALOG_URL. Seeded with the existing 7 RU roles (editorial +
research bundles) plus EN translations.
Server:
- migration: nullable jsonb `source` column on ai_agent_roles
({ slug, language, version }; null => manually created)
- catalog provider: remote fetch with timeout + streaming size cap, or local
read; ^[a-z0-9-]+$ segment guard against path-traversal/SSRF
- admin endpoints: catalog, catalog/bundle, import, update-from-catalog
- import/update match by slug+language; update preserves `enabled`
Client:
- catalog modal with language selector and Import/Installed/Update states
- "Import from catalog" button + empty-state CTA in the roles settings panel
- en-US/ru-RU strings

PR #224 fixed an AI-chat streaming-render regression by moving the React.memo
content signature into the parent: MessageList now snapshots
messageSignature(message) per render and passes it to MessageItem as the
immutable `signature` prop. The existing memo tests only SIMULATED that
parent half by hardcoding `signature={messageSignature(message)}` in their
harness; the real MessageList was never exercised (chat-thread.test.tsx mocks
it out, and there was no message-list.test).
Add message-list.test.tsx that mounts the REAL MessageList (without mocking
MessageItem or messageSignature) and asserts that an in-place mutation of a
reused message object surfaces on re-render. This guards the parent-side
contract: re-caching the signature on message identity (stable across deltas
while parts mutate) would refreeze the row, and this test would fail.
