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.

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.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The floating AI chat rendered NOTHING for the assistant turn (user bubble +
"thinking" dots showed, but the streamed text and tool-call cards never
appeared) even though the agent ran server-side. The parts DID arrive in
`useChat.messages` — this was purely a render freeze.
Root cause: the MessageItem `React.memo` comparator (#182) decided whether to
re-render by recomputing `messageSignature(prev.message)` vs
`messageSignature(next.message)` inside `arePropsEqual` (plus a
`prev.message === next.message` fast path). But the AI SDK (ai@6 /
@ai-sdk/react@3) streams a turn by MUTATING the same `parts` in place and
handing back a message wrapper that SHARES those mutated parts. So inside the
comparator both `prev.message` and `next.message` already reflect the latest
content — the two signatures are ALWAYS equal — and the memo skipped every
post-mount render. The assistant row therefore froze at its initial empty
(null) render; reasoning-first providers (e.g. z.ai/GLM) start with a
non-visible reasoning part, so the whole answer + tool cards never showed.
Fix: snapshot the signature in the PARENT (MessageList) at render time and pass
it to MessageItem as an immutable `signature` string prop; `arePropsEqual` now
compares that prop. A captured string is immutable, so `prev.signature` holds
the previous render's content and `next.signature` the new content — they differ
as the turn streams in and the row re-renders. Drop the now-incorrect
`prev.message === next.message` fast path (same-ref-but-mutated must still
re-render). MarkdownPart's per-part memo is unaffected (it already keys on the
primitive `text`).
Verified end-to-end against a real OpenAI-compatible provider: the assistant
turn (reasoning + streamed text + tool-call card) now renders live and on
finish. Regression tests added (render + comparator) that fail before / pass
after.

- use-open-ai-chat.ts: call setWindowOpen(true) before awaiting
getBoundChat so the header button feels instant on slow connections;
the chat switch (setActiveChatId/setDraft/setSelectedRoleId) is applied
after the round-trip resolves. Also drop the redundant no-op
setWindowOpen(true) in the already-open branch (bare early return).

On opening the floating AI-chat window from the header on a document page,
auto-open the LAST chat bound to that document. Binding reuses the existing
ai_chats.page_id (no migration): the bound chat is the requesting user's
most-recent non-deleted chat created on that page, so a new chat on the page
becomes the bound one for free. Resolution happens only on a genuine
closed -> open transition; the provenance badge deep-link is untouched.
Server: AiChatRepo.findLatestByPage + POST /ai-chat/bound-chat (BoundChatDto),
both read-only and owner/workspace-scoped.
Client: getBoundChat service + useOpenAiChatForCurrentPage hook wired into the
app-header entry point (fail-soft to a fresh chat; draft/role cleared only on a
real switch).
Tests: repo scoping/ordering, controller wiring, and hook behavior.

Port the only substantive fix#211 was missing relative to #203 (which is
being closed): the "Send now" handler branched on the closure-captured
isStreaming, but a turn can finish between render and click. In that window
stop() is a no-op, so arming flushOnAbortRef/interruptNextSendRef would strand
those one-shot flags and leak into a later, unrelated Stop (auto-sending a
queued message the user never asked to send).
- Mirror the live useChat status in statusRef (updated each render) and branch
sendNow on it instead of isStreaming, so the not-streaming path runs when the
turn has already ended and the interrupt flags are never armed against a
no-op stop().
- Belt-and-suspenders: clear flushOnAbortRef/interruptNextSendRef when a new
turn starts streaming, defusing the sub-render-tick window where a flag could
still be armed but the expected abort never fired. No-op for the legit
interrupt path (both refs are consumed synchronously beforehand).
Keeps #211's existing structure and its flushNext-returns-boolean fix. The
rest of #203's divergence is comment rewording, a server-side rename of the
same pure interrupt-gate, and fewer tests — nothing else to port.

- Register the new AI-chat keys "Send now" and "Interrupt and send now" in
both en-US and ru-RU catalogs so the UI never renders mixed-language
tooltip/aria-label (i18n policy).
- Make INTERRUPT_NOTE module-private (drop the unused re-export), matching the
module's private DEFAULT_PROMPT/SAFETY_FRAMEWORK siblings.
- Reset interruptNextSendRef in the flush-on-abort branch when nothing is
actually sent, so a stuck one-shot interrupt flag cannot tag the next
unrelated send; flushNext now reports whether it sent.
- Add a CHANGELOG [Unreleased]/Added entry for #198.

Add an AI button in the page byline that generates a note's title from the
live editor content (including unsaved edits) and applies it immediately.
Server: one-shot, non-streaming POST /ai-chat/generate-page-title mirroring
the chat generateTitle path — gated by settings.ai.generative, throttled via
AI_CHAT_THROTTLER, resolves the workspace chat model and returns { title }.
The endpoint never touches the page; the client applies the title through the
existing /pages/update route (which enforces edit permission).
Client: ai-chat-service.generatePageTitle, a useGeneratePageTitle hook that
converts the editor HTML to markdown, calls the endpoint, applies the title
via updateTitle + updatePageData, reflects it in the unfocused title editor,
and broadcasts the UpdateEvent (mirroring TitleEditor.saveTitle). A sparkles
button (GenerateTitleGroup) renders next to dictation, edit-mode + flag gated.
Tests: pure cleanGeneratedTitle helper + controller gate/delegation/error-map.
i18n: en-US + ru-RU strings.

Add a "send now" button to queued AI-chat messages: it interrupts the
running agent and immediately sends that message, while the agent's
partial output at interruption is kept in history and the next turn is
marked as a user interrupt.
Client:
- queue-helpers: pure `promoteToHead` to move a queued message to the head.
- chat-thread: `sendNow` (promote head + abort + flush-on-abort), one-shot
`flushOnAbortRef`/`interruptNextSendRef`, `interrupted` flag in the
request body, and the "send now" ActionIcon in the queued list.
Server:
- `interrupted` on AiChatStreamBody; pure `isInterruptResume` confirms the
client hint against persisted history (prev assistant turn aborted/
streaming) before honouring it.
- prompt: INTERRUPT_NOTE injected in the context section only on a
confirmed interrupt-resume turn so the model treats the partial answer
above as incomplete.
Tests: promoteToHead, chat-thread send-now (abort + resend + one-shot
interrupt flag + non-streaming immediate send), isInterruptResume, and
the prompt interrupt-note injection.

Code-review follow-ups (Approve-with-comments) for batch #197
(context badge #189 / e2e in CI #187 / inline MCP test #170):
- server: extract the duplicated chatContextWindow ::text->positive-int
coercion (resolve() + getMasked()) into an exported parsePositiveInt
helper and unit-test its branches (200000/1.9/0/-5/""/abc/undefined),
closing the untested read-path gap.

exported selectContextBadge helper (numerator and denominator still
taken from the most recent row carrying EACH value) and unit-test the
different-rows and fresh-zero-doesn't-shadow cases.
- client: extract the MCP "Test" button tristate presentation into a pure
mcpTestButtonView helper (collapses the two parallel if/else chains) and
unit-test idle/ok-with-tools/ok-no-tools/failed label+tooltip branches.

Address non-blocking review items on the AI-chat stream-perf PR:
- Drop the unused `metadata` param from the `msg` test factory in
message-item.test.ts; no caller passed it.
- Add a per-part-kind coupling guard to message-signature.test.ts that, for
each part kind rendered today (text, reasoning, tool-*) plus the metadata
banners, asserts that mutating a field the MessageItem render body DRAWS
flips messageSignature — an executable lock for the load-bearing memo
invariant documented in message-signature.ts.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
PR #182 review (post-fix pass) surfaced two latent correctness risks in the
new MessageItem memo: the per-message signature tracks only [type, text length,
state, error/output presence] + metadata, so a part kind whose VISIBLE content
can change WITHOUT changing those fields would silently freeze a stale row.
Neither is reachable with the current toolset (tool output is set once;
streaming is append-only with a fixed id), so the correct fix is to harden the
documented invariant rather than hash output content on every delta (getPage
returns full page content — hashing it per-delta would tax the hot path this
PR optimizes).
Add a WARNING in messageSignature naming the two future triggers (a tool that
streams `preliminary` output; a client-side regenerate/edit that mutates a
finalized row in place) and the required action (extend the signature).
No behavior change (comment only). vitest src/features/ai-chat 189/189 pass,
tsc clean for the touched files.

The floating chat window's header badge flipped meaning — a live per-turn token
counter while streaming, the persisted context size at rest — so it "reset to 1"
on each prompt and conflated two different numbers. Replace it with a stable
"current / max" context badge (e.g. `572 / 200k`). The live "Thinking · N tokens"
inside the chat body stays; only the duplicate live counter is removed from the
header.
Max comes from a new admin setting "Context window (tokens)". The server resolves
it and attaches `maxContextTokens` to the completed assistant turn's metadata
(next to contextTokens), so the badge needs no client-side model resolution and
this survives public shares / per-role models.
Server:
- ai.types: chatContextWindow on AiProviderSettings + PROVIDER_SETTINGS_KEYS +
ResolvedAiConfig + MaskedAiSettings.
- workspace.repo: chatContextWindow in AI_PROVIDER_SETTINGS_ALLOWED (parity).
- update-ai-settings.dto: @IsInt @Min(0) chatContextWindow.
- ai-settings.service: coerce the ::text-stored value to a positive int in
resolve()/getMasked().
- ai-chat.service: flushAssistant writes metadata.maxContextTokens (>0); the
completed turn passes resolved.chatContextWindow.
Client:
- ai-chat.types: maxContextTokens on the message-row metadata.
- ai-chat-window: read maxContextTokens; render "current [/ max]"; drop the
liveTurnTokens state/branch and the onLiveTurnTokens prop; new tooltip.
- chat-thread: remove the live-turn-token throttle effect and plumbing.
- count-stream-tokens: drop the now-dead liveTurnTokens()/types; keep
estimateTokens.
- settings: chatContextWindow on IAiSettings(+Update) + a NumberInput in the AI
provider settings form.
i18n: add the badge/settings keys (en, ru); remove the two now-unused keys.
Tests: flushAssistant maxContextTokens, DTO validation, trim token tests.

Resolve the PR #182 code-review (Request changes) on top of the already-merged

collapseBlankLines fix in reasoning-block.tsx).
- Extract messageSignature from message-item.tsx into utils/message-signature.ts
(matches the feature's "pure UIMessage helper + colocated test" convention) and
export arePropsEqual so the memo seam is unit-testable. No logic change.
- Add utils/message-signature.test.ts covering every change signal (text grows,
part appended, state flip, output appears, errorText appears, usage.reasoningTokens
arriving on finish-step, metadata error/finishReason) plus the negative
content-identical-clone case.
- Add components/message-item.test.ts for arePropsEqual (each prop diff -> false,
identity fast-path -> true, same-content-different-object -> true, changed -> false).
- Add components/message-item-memo.test.tsx: render-level proof that finalized text
parts are not re-parsed when only a tail part grows (MarkdownPart memo).
- CHANGELOG: add the user-facing 100% CPU freeze fix under [Unreleased] / Fixed.

15-point review of the persistent-history PR. Architecture decisions: crash
recovery = recency threshold; tool-label duplication = leave as-is.
Must-fix:
1. Boot-sweep bounded by recency. sweepStreaming now also requires
`updatedAt < now() - SWEEP_STREAMING_STALE_MS` (10 min), so a fresh replica's
startup sweep can't abort a turn another replica is actively streaming
(multi-instance deploy). Int-spec: a FRESH 'streaming' row is NOT swept, a
STALE one IS.
2. Restore export during the FIRST streaming turn of a new chat (#174). The
server chatId is now adopted EARLY (in-place, on the start-chunk metadata) via
a new `onServerChatId` callback wired through use-chat-session → chat-thread,
so `activeChatId` is set at turn start and the Copy button is live mid-first-
turn (canExport = !!activeChatId). Hook tests for early/in-place/no-op adopt.
3. Cover finalizeAssistant's fallback-insert branch: extracted pure
`planFinalizeAssistant(assistantId)` (update when id present, insert when the
upfront insert failed) + a dispatch harness test for both arms.
Tests: onModuleInit lifecycle spec (sweep called; throw → resolves + warns);
int-spec updatedAt assertion → toBeGreaterThan.
Cleanups: cap findAllByChat at 5000 rows; upfront-insert-failure log carries
chatId+workspaceId; removed the now-dead buildPartialAssistantRecord (only the
spec consumed it; shapes still pinned by the flushAssistant suite); controller
passes `lang: dto.lang` (normalizeLang handles undefined); dropped a no-op
`?? undefined` in errorOf; documented the content-column semantics change
(concatenated step text, UI renders from metadata.parts); CHANGELOG [Unreleased]
entry (#183, #174); reworded the stale LABELS parity comment.
Verified: server build + 323 ai-chat unit + 5 integration; client tsc + 160
ai-chat unit; prettier clean.

The "Thinking" (reasoning) block rendered with large vertical gaps: models
emit reasoning with a blank line (\n\n) between every list item and
paragraph, which `marked` turns into loose lists (each <li> wrapped in a
<p>) and separate <p> paragraphs, each carrying a margin.
- Add `collapseBlankLines(text)`: collapse 2+ newlines to one, EXCEPT inside
fenced code blocks (``` / ~~~) where blank lines are significant. Applied
in reasoning-block.tsx before renderChatMarkdown, so loose lists become
tight (no <li><p>) and paragraphs join; `breaks: true` keeps single \n as
<br>, preserving line breaks. Reasoning-only — the normal answer is
untouched.
- Drop `white-space: pre-wrap` from `.reasoningText`: on the rendered
markdown <div> it turned the newlines between block tags into visible
blank lines on top of the margins. The plain-text fallback <Text> that
needs pre-wrap already sets it inline.
Tests: collapseBlankLines unit (collapse, fence preservation incl. tilde and
unclosed fences) + rendered-HTML assertions that a blank-line-separated list
becomes a tight list and still parses as a list after a paragraph.

The header token badge (and the "Thinking… · N tokens" line) froze between
agent steps and jumped in chunks instead of ticking smoothly. liveTurnTokens
returned the authoritative server `usage` VERBATIM as soon as it appeared, but
the server only attaches usage at a step boundary and it is cumulative over
COMPLETED steps — so during the next (in-flight) step the figure stayed frozen
at the previous boundary and the running text estimate was ignored.
Combine both sources per component via max: always compute the running estimate
(chars/≈4 over the message's reasoning/text parts, which includes the in-flight
step) and take max(authoritativeBase, estimate). Between boundaries the estimate
ticks the number up; at a boundary the authoritative figure snaps it exact; and
because the server usage is cumulative and we only ever take the max, the counter
is monotonic (never drops). Reasoning/output stay split; the #151 reasoning-only
authoritative count is preserved.
Backward compatible: in every existing test the estimate is <= the authoritative
figure, so max returns the same value. +4 tests for the in-flight-step-exceeds-
base case (output + reasoning), the authoritative-wins case, and monotonicity.

Assistant answers containing GFM tables rendered badly in the narrow AI
side panel: `.markdown` only styled p/pre/code/ul/ol and had no table
rules, so tables used the browser default `table-layout: auto`. Combined
with the inherited `word-break: break-word`, columns collapsed to a
single glyph and headers wrapped mid-word ("Секция" -> "Секци / я").
Add table styling scoped to `.markdown`, in line with the editor's
table.css house style:
- make the table a horizontally scrollable block (display:block +
overflow-x:auto) so wide tables scroll instead of squishing;
- give cells a 6em min-width and restore word-boundary wrapping
(word-break:normal + overflow-wrap:break-word);
- add 1px borders, padding and a th background (light-dark for dark
mode); zero out the default <p> margin inside cells.
CSS-only; no markdown-pipeline change (marked already emits GFM tables,
DOMPurify already allows table tags). Applies to the public share too.

The chat lived in inconsistent paradigms (in-memory stream + client export vs.
DB-as-context), which made export flaky and lost the assistant answer if the
process died mid-turn. Make the DB the single source of truth.
A. STEP-GRANULAR DURABILITY (server)
- ai_chat_messages gains a nullable `status` column (migration; NULL = legacy =
completed). The assistant row is now INSERTED UPFRONT as `status:'streaming'`
and UPDATEd on every onStepFinish with all finished steps (text + tool calls +
tool RESULTS), then finalized once to completed/error/aborted on the terminal
callback. So a process death mid-turn keeps every finished step; a startup
sweep (OnModuleInit → sweepStreaming) flips any dangling 'streaming' row to
'aborted'. The write path no longer depends on a live socket.
- Pure exported `flushAssistant(steps, inProgressText, status, extra?)` builds
the persist payload (metadata.parts byte-identical to the old builder), so a
future background worker can call the same path. AiChatMessageRepo gains
`update`, `sweepStreaming`, and `findAllByChat`.
- consumeStream drain, external-MCP client close-once, SSE heartbeat preserved.
B. SERVER-SIDE EXPORT
- New pure `chat-markdown.util.ts` renders Markdown from DB rows ONLY (server
port of the client builder). Because A persists the in-progress row, the
export now includes an interrupted turn up to its last finished step (flagged
"still generating"). `POST /ai-chat/export` (owner-gated via assertOwnedChat,
workspace-scoped) returns it; `lang` accepts a full client locale tag
('en-US'/'ru-RU') and is normalized server-side (normalizeLang) — a strict
@IsIn(['en','ru']) DTO rejected the real client's i18n.language with a 400,
caught in real-browser testing.
- Client: handleCopy calls the endpoint; `canExport = !!activeChatId`. The whole
liveThreadRef/liveStateRef/onLiveContentChange/hasLiveContent hybrid (and the
client chat-markdown util + test) is removed — the server is now authoritative.
Tests: flushAssistant unit (status shapes + parts parity), chat-markdown.util
unit (incl. legacy NULL-status + interrupted note + ru + normalizeLang locale
tags), controller export wiring + owner-gate, integration update/sweepStreaming.
Verified: server build + 318 ai-chat unit + 3 integration; client tsc + 157
ai-chat unit; and END-TO-END in a real browser — a chat turn persists mid-stream
and the Copy button exports the DB-sourced markdown (showing the in-progress
row), HTTP 200 after the locale fix.

The "Copy chat" button was hidden during a brand-new chat's very first
turn: both the `canExport` gate and the `handleCopy` early-return required
an `activeChatId` AND persisted `messageRows`, neither of which exists yet
while the first turn is streaming or after it was interrupted before any
row was persisted.
Decouple the export gate from persisted state. ChatThread now reports a
reactive `onLiveContentChange(messages.length > 0)` signal (the live
snapshot lives in a non-reactive ref, so a separate reactive flag is
needed to re-render the button); the parent keeps it in `hasLiveContent`
and exports whenever there is anything on screen OR persisted. `handleCopy`
passes a `"unsaved"` placeholder chat id when none exists yet, and the
live-first builder serializes the on-screen thread WYSIWYG.
Builds on #160 (WYSIWYG export); covers the first-turn edge case that was
explicitly out of scope there.

"Copy chat" built the Markdown from persisted rows plus a live tail that was
only included while isStreaming. When a turn was interrupted (dropped stream /
"Lost connection" banner) isStreaming flipped false, the live tail was dropped,
and the partial assistant reply visible on screen — whose row often never
persisted — vanished from the export, leaving only the user messages.
- buildChatMarkdown is now live-first: the on-screen `live` messages ARE the
document. Each is matched to a persisted row by id to enrich it with token
usage / error / timestamp; authoritative usage/error already on the live
message win over the row. When `live` is empty it falls back to the persisted
rows (old format preserved). Only the tail assistant is flagged "still
generating", and only when it is genuinely the streaming tail — so the
status==="submitted" window (tail is the user message) never mislabels the
previous, completed answer.
- The on-screen banner (classified error / dropped connection / manual stop) is
flattened to a string in ChatThread, mirrored into liveStateRef alongside the
messages/isStreaming snapshot, and appended at the end of the export.
- handleCopy maps the live messages and passes live/rows/isStreaming/banner.
Tests: chat-markdown rewritten for the live/enrichment/fallback/banner paths and
the submitted-window regression (26); full ai-chat suite green (186). tsc clean.

On long agent runs (dozens of tool calls) the desktop app froze at 100% CPU with
no user interaction: useChat updated state on every streamed token, and
MessageItem/ReasoningBlock re-parsed the whole transcript's markdown (the marked
pipeline + DOMPurify) on every delta. Per-turn work grew quadratically and
saturated the main thread; the SSE stream drove it, so it hung "on its own".
- chat-thread: pass experimental_throttle (50ms) to useChat so the streamed
messages state re-renders at most ~20 Hz instead of once per token.
- message-item: memoize MessageItem on a cheap per-message content signature
(the streaming tail still re-renders as it grows; finalized rows are skipped),
and render each text part via a memoized MarkdownPart so finalized parts are
not re-parsed. The signature includes usage.reasoningTokens so the
authoritative "Thinking - N tokens" count still snaps in at finish-step.
- reasoning-block: memoize the markdown render (useMemo on the text) and wrap the
component in React.memo.

showTypingIndicator hid the standalone thinking dots for any non-empty
trailing text part, so during the pause after the model finished an
intermediate narration and before its next step (e.g. a tool call) the
UI looked frozen. Suppress the dots only while the text part is still
streaming: a finalized ("done") trailing text part on an in-flight turn
now shows the dots again, matching the function's documented intent.
- message-list: guard the text branch with state !== "done" (AI SDK v6
TextUIPart.state); stateless parts keep their previous behavior
- show-typing-indicator.test: add done -> shown and streaming -> hidden cases

The name label was crowding the bouncing dots when displayed. Adding extra bottom margin (mb={8}) gives the dots room and improves readability. The change only applies when the name is shown.
The live typing placeholder now shows only the bouncing dots; the
"Thinking… · N tokens" line is removed. Clean up the dead plumbing:
- typing-indicator: remove thinkingTokens prop, thinkingLine and the
<Text> line; keep the animated dots and the dimmed name label
- message-list: remove tailThinkingTokens helper, the thinkingTokens
prop pass-through, and the now-unused liveTurnTokens import
- delete tail-thinking-tokens.test.ts (tested the removed helper)

Review of #158 (Request changes) — core logic verified correct; addressed the
test-coverage + localization items:
1. i18n pluralization: the token-count keys were called with {count} but had one
form, so ru-RU always rendered the genitive ("1 токенов"). Added _one/_other
(en) and _one/_few/_many (ru: токен/токена/токенов) for both "Thinking… ·
{{count}} tokens" and "Thinking · {{count}} tokens"; de-duped the PR-added
duplicate "Thinking" key. Call sites unchanged.
2. ReasoningBlock: new reasoning-block.test.tsx (4 branches: authoritative count
wins / estimate fallback / header-only when count-but-no-text / body render).
3. Reasoning-token attribution: extracted the #151 anti-double-count rule into a
pure `reasoningTokensForPart(message)` (single reasoning part -> authoritative
turn total; multiple/none -> undefined so each estimates). message-item uses
it; removed the now-dead lastReasoningIndex reduce (review #5). Unit-tested.
6. adopt-chat-id.ts: refreshed 3 stale `chatStreamStartMetadata` ->
`chatStreamMetadata` comment references.
7. chat-markdown.test.ts: assert the export footer's `reasoning: N` line appears
when reasoningTokens>0 and is absent at 0/undefined.
Skipped optional #4 (mantine useThrottledCallback): the manual throttle has two
distinct exit paths (turn-end revert-to-null + the captured-total trailing emit)
with no guarding test; remapping risks the streaming behavior — non-blocking.
Client tsc clean; ai-chat suite green (171 tests).

Review of #156 (Request changes) flagged the new CLIENT logic as untested. Extract
the decision logic from chat-thread.tsx into pure, unit-testable helpers and cover
both branches the reviewer called out:
- `roleLaunchMessage(role, default)` — the three-way handleRolePick behavior:
autoStart=false -> null (send nothing); autoStart=true + custom -> trimmed
message; autoStart=true + empty/null/whitespace -> default fallback.
- `shouldResetRolePicked(chatId, roleId, flag)` — the #149 render-phase reset; the
regression test asserts the stuck-flag case (New chat after an autoStart=false
pick -> cards return) that the pre-fix code never handled, and that a still-bound
role keeps the cards hidden.
chat-thread.tsx now calls these helpers (behavior unchanged). 9 new pure tests.
Also folded the review's cosmetic suggestion: `x ? x : null` -> `x || null` in
ai-agent-roles.repo.ts (identical for string|null|undefined).
Client tsc clean; role-launch + role-cards green; repo spec green.

Tokens were only counted post-hoc (onFinish) and the header badge updated only on
chat open/switch; reasoning wasn't requested or shown. Now a counter ticks LIVE
during generation and surfaces reasoning ("thinking") tokens separately, like
Claude Code's `Thinking… · N tokens`.
Architecture (AI SDK v6): no provider gives exact per-token usage mid-stream, so
the live number is a cheap client estimate (chars/≈4) reconciled to AUTHORITATIVE
provider usage at step boundaries and turn end. The useChat per-delta re-render is
the existing realtime engine.
- server: `chatStreamMetadata` now also forwards usage on `finish-step` + `finish`;
`sendReasoning: true`; persisted `metadata.usage` carries `reasoningTokens`
(normalized from `outputTokenDetails` or the deprecated field).
- client: pure `count-stream-tokens` (estimateTokens / liveTurnTokens, prefers
authoritative usage else estimate); `Thinking… · N tokens` in the typing
indicator; collapsible "Thinking" reasoning block; throttled (~8 Hz) live
turn-token header badge; `reasoningTokens` in types + Markdown export.
Review fixes folded in:
- v6 `finish-step.usage` is PER-STEP, not cumulative — the server now ACCUMULATES
a running sum (new pure `accumulateStepUsage`) and sends the cumulative, which
converges to `finish.totalUsage`, so the live counter never jumps DOWN on a
multi-step agent turn.
- reasoning double-count: the authoritative turn-total is attributed to a block
ONLY for a single-reasoning-part (one-step) turn; multi-step blocks each show
their own estimate (the authoritative total stays in the header).
- no "0" badge flash at turn start (require live > 0, else show context size).
- comment refreshed (finish-step trigger).
Tests: server `accumulateStepUsage` + updated `chatStreamMetadata` (34 in the
suite); client pure-fn tests. Both tsc clean; 162 client ai-chat + the ai-chat
server suite pass.

Agent role cards always auto-sent a hardcoded "Take a look at the current
document" on pick. Make it configurable per role:
- autoStart (bool, default true): whether picking the role auto-sends a message.
- launchMessage (nullable text): the text sent on auto-start; empty -> the
built-in default. autoStart=false -> bind the role and send nothing (the user
types the first message, which still carries the roleId).
Existing roles default to autoStart=true / launchMessage=null => identical old
behavior.
Full-stack:
- migration 20260624T120000 adds `auto_start boolean NOT NULL DEFAULT true` +
`launch_message text` (additive; down drops both); db.d.ts updated by hand.
- DTO: autoStart (@IsBoolean) + launchMessage (trim @Transform, @MaxLength 2000).
- repo/service: thread + normalize (undefined=unchanged, ""=>null, autoStart??true).
Both fields exposed in the picker-view for ordinary members (they decide
whether/what to auto-send); instructions/modelConfig stay ADMIN-ONLY.
- client: IAiRole types, role form (Switch + Textarea, re-hydrated on edit),
handleRolePick branches on autoStart; i18n en-US + ru-RU.
Review follow-ups folded in: reset the `rolePickedNoSend` flag when the thread
returns to an empty role-less state (the "New chat after autoStart=false pick"
stuck-UI bug — render-phase one-shot reset); made create/update launchMessage
normalization symmetric (raw value, server normalizes ""→null).
Server: 68 role tests pass, tsc clean. Client: tsc clean, role tests pass.

The standalone "Thinking…" indicator's agent-name label switched owners a couple seconds into a turn: at first TypingIndicator rendered name+dots (4px gap), then once useChat materialized the empty/reasoning-only assistant message the name moved to the empty MessageItem row (16px messageRow margin), pushing the dots ~20px away — a visible layout jump.
Introduce a shared pure helper assistantMessageHasVisibleContent() as the single source of truth mirroring MessageItem's render decisions. MessageItem now returns null for an assistant message with no visible content, and typingIndicatorShowsName keeps the name on the indicator until the assistant row has visible content. Exactly one element owns the name throughout the pre-content gap, so the layout no longer reflows.
- new utils/message-content.ts + unit tests (12 cases)
- message-list.tsx: typingIndicatorShowsName uses the helper
- message-item.tsx: early return null when no visible content
- typing-indicator-shows-name.test.ts: updated expectations

- [warn 1] Document the is_agent operator setup so it survives plan deletion:
added an AI-agent block to .env.example (use a DEDICATED account, set is_agent
via SQL, never flag a human/shared account) + a CHANGELOG "Added" entry.
- [warn 2] Test the badge deep-link side effects: ai-agent-badge.test.tsx now
renders inside an explicit jotai store, clicks the badge, and asserts the
active chat id, window-open, cleared draft, closed history modal, AND that
stopPropagation keeps a parent onClick from firing.
- [suggestion 3] Hoist the window.matchMedia stub into vitest.setup.ts and drop
the duplicated beforeAll block from the three test files (ai-agent-badge,
comment-list-item, role-cards).
- [suggestion 4] Merge the two near-duplicate "non-clickable" cases via it.each.
- [follow-up 6] Introduce a single ProvenanceSource = 'user' | 'agent' type in
jwt-payload.ts and reference it from AuthProvenanceData, JwtPayload/
JwtCollabPayload, and resolveSource() — so a typo can't slip through as a bare
string. (Server auth chain; client IComment mirroring left as a follow-up.)
Follow-up 5 (shared agentSourceFields write-stamp helper) is deferred as the
review marked it — the 6 REST sites use varied shapes (create-spread vs
resolve-conditional-null vs page move), so it's a separate focused refactor.
Tests: client badge/comment/role-cards suites 11/11 pass; server auth+comment
suites 62 pass; typecheck clean.

While a multi-step agent turn is "thinking between tool steps", the
assistant identity name (e.g. the role name) was rendered twice, stacked:
once by the assistant message row (MessageItem) and once by the standalone
TypingIndicator below it. The indicator's name label only makes sense when
it stands in for a not-yet-started assistant row; between steps the row
above already shows the same name.
Render the indicator's dimmed name label only when it is standalone (no
assistant row at the tail yet); otherwise show just the "Thinking…" dots.
- typing-indicator.tsx: optional showName prop (default true); the name
label renders only when showName !== false
- message-list.tsx: exported typingIndicatorShowsName(messages) helper;
pass showName to the indicator at the render site
- typing-indicator-shows-name.test.ts: unit-cover the four cases

Closes the 4th PR #138 review (3 suggestions, no blockers).
- Double-call safety: a failed turn fires both useChat onFinish AND onError, so
onTurnFinished can run twice in one turn (streamed id, then no id) before a
re-render. onTurnFinished now reads the live id from a ref (set imperatively on
primary adoption) instead of the stale closure, so the 2nd no-id call cannot
re-arm the error-path fallback at the source; the render-phase reconciler is the
second layer. Added a hook test for the sequence — verified it fails only if
BOTH layers are removed (non-tautological).
- Conventions: extracted named UseChatSessionOptions / UseChatSessionResult
interfaces (was an inline param literal + ChatSession); the test derives its
driver props from them.
- Simplification: extracted the chatIdSnapshot(chats) projection used at both the
fallback arm site and the resolver effect.
Architecture notes from the review (caller-driven disarm contract; cross-process
{chatId} type) intentionally left as Variant A per the reviewer's recommendation.
tsc clean; 128 ai-chat tests green.

Closes the 3rd PR #138 review.
Warning fix: the render-phase reconciler only disarms the error-path adoption
fallback when activeChatId actually changes. Pressing 'New chat' while ALREADY
in a new chat keeps activeChatId === null (a no-op atom write), so the reconciler
never fired and a stale armed fallback could adopt the just-failed chat from a
late refetch, yanking the user out of their fresh chat. useChatSession now
returns cancelPendingAdoption(); the window calls it from startNewChat AND
selectChat. (The hook call moved above those callbacks so they can reference it.)
Added a hook test that fails without the explicit disarm, plus a test for the
existing-chat onTurnFinished branch (no adoption + per-chat invalidation).
Cleanups: removed the dead pickNewlyCreatedChatId (the fallback effect uses
newlyAddedChatIds directly with the 0/1/>1 decision inline) and its tests/doc
mention; inlined the two invalidation closures (onTurnFinished is read live by
useChat's onFinish, never in an effect dep array, so memoizing them was needless
ceremony).
Verified: tsc clean, 127 ai-chat tests green; live (z.ai glm-5.2) new chat + 2nd
turn recalled the number in the SAME row (1 chat / 4 messages), no page errors.

Addresses the 2nd PR #138 review (test debt + the Variant-B architecture ask).
The new→persisted chat id lifecycle (mount key, both adoption paths, the
history-load latch, the render-phase reconciler, onTurnFinished) is moved out of
the 768-line window into a new useChatSession hook driven by a pure
threadSessionReducer (reconcile/adopt), so adopt-vs-switch is one explicit
dispatch point and the scattering the review flagged is gone (window: 768→~620).
Tests (the blockers):
- use-chat-session.test.tsx — hook-level locks incl. the #137 regression
(adopts the authoritative streamed id 'A', NOT chats.items[0]='B' — fails on
the old heuristic), the error-path fallback (arm/adopt/ambiguous/add+delete),
the disarm-on-reconcile lock (a fallback armed then switched away must not be
adopted by a late refetch), in-place-adopt-keeps-key vs external-switch-remount,
and the waitingForHistory latch.
- extractServerChatId (reading message.metadata.chatId) and newlyAddedChatIds
extracted as pure helpers with unit tests; threadSessionReducer tested.
Cleanups: single canonical #137 explanation in adopt-chat-id.ts (other sites
reference it); fallback effect computes the set diff once; invalidate callbacks
memoized; redundant invariant tests folded.
Behavior preserved — re-verified live (z.ai glm-5.2): new-chat adopt + 2nd turn
in the same row, no mid-conversation remount, two-tab race leak-free, switch to
an existing chat reseeds full history, reload restores history.

Addresses the PR #138 review's architecture note (the deferred 'non-blocking'
item). The brand-new -> persisted chat identity was spread across two separate
useState slots (threadKey + liveThreadChatId) plus a render-phase guard, so the
mount key and the live thread's chat id could in principle diverge.
Consolidate them into ONE atomic state object { key, chatId } with pure,
unit-tested transitions in thread-identity.ts:
- newThread(newKey) — a brand-new id-less chat (fresh session key);
- switchThread(chatId) — switch to an existing chat (key := chat id) -> remount;
- adoptThread(prev, id) — a new chat learns its real id IN PLACE (key unchanged
-> no remount, live useChat store preserved).
The 'key vs chatId diverged' state is now unrepresentable. The render-phase
reconciliation stays (the atom is also set externally, e.g. page-history's
history-item opening a referenced chat), but adoption vs switch is now explicit.
Behavior is unchanged; verified live: new-chat adopt + 2nd turn in the same row,
no mid-conversation remount, the two-tab race stays leak-free, switch-to-existing
remounts + reseeds, and reload restores full history. Adds thread-identity.test.ts.
