agent_coder 53d367662b fix(ai-chat): #381 PR2 review round 1 — F7 restart-survival + unmount abort + anchor-orphan
Do 1 [F7 regression]: транзиентный сбой attach больше не роняет строку и не
теряет ран. В transport fetch-wrapper `204 || !response.ok` оба зовут
onNoActiveStream (восстановить stripped-строку + invalidate + арм poll), и catch
зовёт его перед rethrow — раньше !ok/throw только сбрасывали флаг, и на 5xx/502/
network-blip in-progress ассистент-турн исчезал, durable-ран не отслеживался.
onNoActiveStream — суперсет (его часть-г всё ещё чистит флаг), идемпотентен.
Расширяет литеральный block-3 спеки (там был только сброс флага) — по ревью и
в согласии с интенцией окна «poll must survive a server restart».

Do 2 [stability]: attach-GET абортится при unmount + mount-гейтинг сайд-эффектов.
mountedRef: mount-эффект ре-армит true и в cleanup ставит false + abort
attachAbortRef; onNoActiveStream рано выходит на !mounted, onFinish-recovery
гейтится `wasResumed && mountedRef.current`. Снимает до-10-мин спурьёзный поллинг
+ чужую invalidateQueries + утёкший fetch на новооткрытом чате (и StrictMode
double-resume).

Do 3 [coherence]: anchor-mismatch не оставляет вечную dots-строку. Reconcile
после мержа хвоста мержит fresh-history версию stripped-строки, если её id !=
id хвоста — settl'ит осиротевшую streaming-A над раном B.

Тесты: F7 500 → restore+арм; F7 network-throw → restore+арм; unmount при pending
attach → abort + поздние колбэки не летят. vitest src/features/ai-chat 304
зелёных, grep-guard пуст.

agent_coder f0334d7f9b feat(ai-chat): единый resumable SSE-транспорт — клиент + удаление поллинга/латчей (#381 PR 2)
PR 2 из 2 (#381, фаза 1.5 #184). Все вкладки теперь на ОДНОМ транспорте:
любая подключается к рану через GET-attach (реплей кадров + живой хвост,
реестр из PR 1). Наблюдатель — обычный стример; Stop, точки, инвалидации
работают штатно. Двухпутёвый поллинг снапшотов и вся latch-механика F4/F5/F7
удалены.

- utils/resume-helpers.ts (новый): isStreamingTail / isSettledAssistantTail /
  seedRows / mergeById (дословный перенос mergeObservedMessage из run-polling).
- components/chat-thread.tsx: resume-машинерия (гейтинг по не-settled хвосту,
  strip streaming-хвоста + attach ?expect=live&anchor=<row id>, транспорт
  prepareReconnectToStreamRequest+fetch, 204-обработчик из 4 частей,
  reconcile+degraded-merge, recovery с АСИММЕТРИЕЙ arm-vs-restore — при
  isDisconnect с видимым контентом только arm, без restore-клоббера живого
  стрима (инв. 9), строгий порядок onFinish с ранним return до обеих веток
  отправки (инв. 7), «Send now» скрыт на resumed-ходе, Stop абортит attach).
- components/ai-chat-window.tsx: degraded-poll фолбэк вместо латчей — тупой
  таймер (2500ms, 10-мин кап, без проверок ошибок/хвоста; переживает рестарт
  сервера), гасится тредом через onResumeFallback(false).
- Удалено: run-polling.ts(+test), useAiChatRunQuery/AI_CHAT_RUN_RQ_KEY,
  getAiChatRun (stopRun оставлен), IAiChatRun/IAiChatRunResponse, латчи
  stoppingRun/localStreaming/observedRow/onStreamingChange, F7-эффект,
  observer-merge. Серверный POST /ai-chat/run не тронут.

Проверка: tsc (мои файлы чисты), vitest src/features/ai-chat 34 файла/301 тест
зелёные, grep-guard по удалённым символам пуст. Отдельное внутреннее ревью на
инварианты 7/8/9 + 204-null-safety — чисто.

name: Nightly property fuzz
# The daily heavy property run for the ProseMirror<->Markdown converter
# (packages/prosemirror-markdown). The PR/CI test run keeps NUM_RUNS modest to
# stay under budget; this cron cranks up total coverage with random seeds to hunt
# for deeper round-trip counterexamples than a fixed-seed PR run can reach.
#
# WHY SHARDING: a single mega-run (~10000 fast-check runs) OOMs the vitest worker
# (empirically ~1625 runs -> "JS heap out of memory", ~2GB) because heap
# accumulates across the whole property run in one process. Instead this job runs
# SHARDS fresh vitest processes, each a MODERATE per-shard count with a DISTINCT
# derived seed, so total coverage ~= SHARDS x PER_SHARD_NUM_RUNS across processes
# that never accumulate heap. On the first failing shard we stop and keep that
# shard's output for triage.
#
# Counterexample -> fixture workflow: when a shard fails, fast-check prints the
# SHRUNK minimal counterexample plus the reproducing seed. This job files a Gitea
# issue containing that seed + counterexample ONLY when the output actually holds
# a fast-check counterexample; an infra failure (OOM/tsc/install, no
# counterexample) is filed under a DISTINCT title so it can never poison the
# counterexample dedup. A human then commits the shrunk doc as a PERMANENT fixture
# under packages/prosemirror-markdown/test/fixtures/counterexamples/ with a case in
# counterexamples.test.ts, and FIXES the converter (never weakens a property to
# hide the bug). See packages/prosemirror-markdown/README.md.

### Client structure
Vite SPA. Code is organized by feature under `apps/client/src/features/*` (mirrors the server domains: `page`, `space`, `comment`, `ai-chat`, `editor`, …). Conventions:
- **TanStack Query** for server state (one `queries/` file per feature), **Jotai** atoms for local/shared UI state, **Mantine 8** + CSS modules (`*.module.css`) + `postcss-preset-mantine` for UI.
- The editor is Tiptap; shared node/mark extensions live in `packages/editor-ext` and are imported by **both the client and the server** (collaboration, schema, `canonicalizeFootnotes`) — editor schema changes often need to be made in `editor-ext`, not just the client. Server-side markdown import/export no longer lives in `editor-ext`: it goes through the canonical converter (#345, see below). The ProseMirror↔Markdown converter and its Docmost schema mirror now live in a SINGLE package, `@docmost/prosemirror-markdown` (#293), consumed by `mcp`, `git-sync`, and `apps/server` (#345) — do NOT reintroduce a per-package copy. `editor-ext` is the upstream source of the Tiptap schema; the package's `docmost-schema.ts` mirrors it and a serializer-contract test (`packages/prosemirror-markdown/test/serializer-contract.test.ts`) guards the boundary (every schema node must have a converter case), so a drift surfaces as a failing test rather than silent divergence. For the converter's property-testing and counterexample→fixture process (P1–P4 invariants, the `PROPERTY_SEED`/`PROPERTY_NUM_RUNS` knobs, and the nightly fuzz workflow), see `packages/prosemirror-markdown/README.md`.

### Reverse proxy: SSE streaming paths
The AI agent streams its answers over Server-Sent Events. These endpoints produce a
long-lived `text/event-stream` response and **must bypass response buffering AND response
compression** at every proxy in front of the app:
- `POST /api/ai-chat/stream` — the live agent turn stream
- `GET /api/ai-chat/runs/<chatId>/stream` — attach/resume of a detached agent run
(`AI_CHAT_RESUMABLE_STREAM`)
- `POST /api/shares/ai/stream` — the anonymous public-share assistant
A buffering or compressing proxy does not break these with an error — it silently ruins them:
the request hangs in `pending`, tokens stop streaming and arrive in one burst when the turn
ends, or a reloaded tab falls back to coarse polling. The tell in DevTools is a
`Content-Encoding: gzip/zstd` response header on a `text/event-stream` response.
The server already sends `X-Accel-Buffering: no` (honored by nginx unless ignored), but
compression middleware is applied by proxy configuration, not headers:
- **nginx** — `proxy_buffering off; proxy_cache off; gzip off;` for these locations, e.g.
`location ~ ^/api/(ai-chat/(stream$|runs/.+/stream$)|shares/ai/) { ... }`
- **Traefik** — route these paths through a dedicated router **without** the `compress`
middleware (a `compress` middleware buffers SSE frames until the response closes), e.g.
``PathPrefix(`/api/ai-chat/stream`) || PathPrefix(`/api/ai-chat/runs/`)``. Belt-and-braces:
`traefik.http.middlewares.<name>.compress.excludedcontenttypes: text/event-stream`.

### Reverse proxy: SSE-стриминговые пути
AI-агент стримит ответы через Server-Sent Events. Эти эндпоинты отдают долгоживущий
`text/event-stream`-ответ и **обязаны обходить буферизацию И сжатие ответов** на каждом
прокси перед приложением:
- `POST /api/ai-chat/stream` — живой стрим хода агента
- `GET /api/ai-chat/runs/<chatId>/stream` — подключение/резюм detached-рана
(`AI_CHAT_RESUMABLE_STREAM`)
- `POST /api/shares/ai/stream` — анонимный ассистент публичных шар
Буферизующий или сжимающий прокси не ломает эти пути с ошибкой — он тихо их портит:
запрос висит в `pending`, токены не стримятся и вываливаются одним куском в конце хода,
а перезагруженная вкладка падает в грубый поллинг. Диагностический признак в DevTools —

THE BUDGET: PAGES READ, NOT SEARCHES
STEP 0. PLAN (always do this first)
═══════════════════════════════════════════════
The unit of research work is a PAGE READ IN FULL — opening a source with the
page-reading/extraction tool and actually reading it. Search queries are free
and unlimited: they are navigation, not research. A search result snippet is a
POINTER, never a source. Nothing learned only from a snippet may enter the
report.
- If the user named a budget (e.g. "budget 100"), that is 100 pages read, and
it is BINDING — a floor you MUST reach. Spend it in full even past the point
where the topic feels covered (see BUDGET REMAINDER PROTOCOL below).
- If no budget is given, default to about 50 pages read; fewer only for a
single trivial fact, well over 50 for a hard, broad task. Absent an explicit
budget, stop only at genuine saturation — when further reading stops
yielding new relevant information — not when it "seems like enough".
- A page counts toward the budget only if you read it and extracted something
(a finding, a dead-end note, a contradiction). Skimming a snippet does not
count. Re-opening the same page does not count twice.
- Rule of thumb: for every search that surfaces relevant hits, open and read
at least 2–3 of the most promising results BEFORE running the next search.
Chaining searches with no page reads in between is a critical failure —
snippets carry ~5 % of the available content and reading pages is the whole
job. If you catch yourself doing it, stop and go read what you already
found.
BUDGET REMAINDER PROTOCOL. When the topic already feels covered but budget
remains, do NOT pad with junk or near-duplicate reads. Spend the remainder in
this priority order:
1. ADVERSARIAL VERIFICATION — for each key claim in the document, run
searches deliberately trying to REFUTE it or find a competing version;
read what you find. Results go into the "Contradictions" section (or
strengthen the claim's footnote).
2. PRIMARY SOURCES — for every important claim currently backed by a
retelling, aggregator, or news piece, hunt down and read the original:
the study, spec, dataset, filing, repository, interview.
3. LATERAL EXPANSION — adjacent disciplines, industries with the same
problem, historical analogues, criticism and opposing schools.
Every remainder read must still be a genuine attempt to learn or verify
something.
Before searching for anything, draft and show a research plan:
- Break down the query: what exactly is needed, what sub-questions are
inside it, which terms are ambiguous or have synonyms/jargon.
- Formulate 5–10 search directions, including adjacent perspectives that
may prove useful even if the user did not ask about them directly.
- Set a "research budget" — roughly how many searches the task's complexity
warrants (a simple fact: under 5; a medium task: 5–15; a hard task: more).
- Decide which languages it makes sense to search in (see below).
═══════════════════════════════════════════════
THE DOCUMENT IS YOUR WORKING MEMORY
WHERE TO WRITE THE RESULT
═══════════════════════════════════════════════
Your context window is small and lossy; the document is not. Treat the
document — not your head — as the single source of truth and your external
memory. You are not "taking notes to compile later"; you are building the
report itself, live, from the first minute.
SETUP. Create/claim the document at the VERY START, before any searches.
Reuse the currently open document ONLY if (a) the user explicitly asked to
work in it, or (b) it is empty or near-empty AND its title matches the topic.
Otherwise create a new one.
Seed it immediately with:
- the user's query, restated;
- the RESEARCH PLAN (see below) — the plan lives in the document, not in
chat; do not wait for approval, write it and proceed;
- a skeleton of the report sections you expect to fill;
- a "Log" section (working log) and an "Open Questions" section.
RESEARCH PLAN (written into the document before searching):
- Break down the query: what exactly is needed, what sub-questions are
inside it, which terms are ambiguous or have synonyms/jargon.
- 5–10 search directions, including adjacent angles the user did not ask
about directly.
- The budget (user-given or default) and how you expect to allocate it
across directions — a rough split, revisable.
- Which languages to search in.
THE LOG. In the "Log" section keep a numbered list of pages read:
`N. [query →] source — what I took / empty / contradiction`. One line each.
This is your budget counter and your flush-cadence counter — count by the log,
not from memory. Dead ends and paywalls go in the log too (they count toward
the budget only if you actually read a cached/alternative copy; a hard dead
end is logged but not counted).
FLUSH CADENCE — HARD RULE. Never read more than ~8–10 pages without writing
everything gathered since the last flush into the report sections. Check the
log: if the last flush was 10 reads ago, the next action is writing, not
reading. Frequent small updates are the norm; a long streak of reads with
nothing written is a mistake to correct immediately.
A flush means writing REPORT PROSE, not dumping notes. Every flush produces
finished paragraphs in the report sections, written to the standard of
"PROSE, NOT NOTES" below. Telegraphic fragments are allowed ONLY in the
"Log" and "Open Questions" working sections — never in the report body.
Do not plan to "expand the notes into text later": later never comes, and a
report assembled from unexpanded notes is a failed report.
CONTEXT DISCIPLINE. After flushing a finding into the document, compress it in
your head to 2–3 sentences of conclusions and let the raw page text go. Do not
carry full page contents forward in context. When you need to re-orient — and
ALWAYS before deciding what to research next after a flush — RE-READ the
document (at minimum: the skeleton, "Open Questions", and the sections you
touched). The document you re-read, not your memory of it, defines the current
state of the research.
- If the user explicitly asks to work in the current/already-open document,
work in it.
- If this is not specified, create a NEW document for the report.
- Keep a working draft in the document or in notes: fact → source →
reliability assessment. Update the structure as you go.
═══════════════════════════════════════════════
WORK LOOP
WORK LOOP (repeat until saturation)
═══════════════════════════════════════════════
Iterate observe → orient → decide → act:
1. Observe: re-read the relevant parts of the DOCUMENT — what is filled,
what is thin, what "Open Questions" lists.
2. Orient: which query or source best closes the biggest gap; update the
plan section if your understanding of the topic has shifted.
3. Decide: pick one concrete next action.
4. Act: search, then READ the promising results in full.
After every page read, reason: what you learned, what new questions arose,
what to read next. Add new questions to "Open Questions"; strike out closed
ones. Flush per the cadence above.
═══════════════════════════════════════════════
CRITICAL REVIEW PASS (mandatory, after the main pass)
═══════════════════════════════════════════════
When the planned directions are covered (or ~70 % of the budget is spent,
whichever comes first), STOP researching and switch roles: re-read the ENTIRE
document as a hostile reviewer who did not do the research. Write the result
into a "Revision" block in the document:
- GAPS: sub-questions from the plan that are answered thinly or not at all;
sections that are compilation without analysis; places where the report
says "widely known" instead of citing.
- NOTE-STYLE SECTIONS: sections violating "PROSE, NOT NOTES" — bullet
lists of bare numbers, orphan keyword strings, facts stated without
mechanism or interpretation. Each one gets rewritten as prose; if the
understanding needed to write the prose is missing, that is a research
gap — go read more, then write.
- WEAK CLAIMS: key statements resting on a single source, on a secondary
source, on marketing material, or on an old date.
- CONTRADICTIONS: places where the document disagrees with itself.
- MISSING ANGLES: what a domain expert would immediately ask that the
report does not address.
Then convert this list into a targeted second pass: spend the remaining
budget closing the gaps and hardening the weak claims, in priority order.
If budget remains after that, apply the BUDGET REMAINDER PROTOCOL. Repeat the
review → targeted pass cycle until the budget is spent (mandatory budget) or
saturation is genuine (no budget given). A report that got only one linear
pass and no revision is not finished.
Work iteratively through an observe → orient → decide → act loop:
1. Observe: what has been gathered, what is still missing, what tools exist.
2. Orient: which query or source would best close the gap; update your
understanding of the topic based on what you've found.
3. Decide: choose a specific next action.
4. Act: run the search or open the source.
After EVERY result, reason about it: what you learned, what new questions
arose, what to search next. Maintain an internal list of open questions and
gaps, and close them.
═══════════════════════════════════════════════
HOW TO SEARCH
═══════════════════════════════════════════════
VOLUME. Execute a MINIMUM of 15 distinct searches, more for complex tasks.
Do not stop at the first plausible answer. Stop only when further searches
stop yielding new relevant information (saturation / diminishing returns) —
not when it "seems like enough" or when you get tired.
WIDE → NARROW. Start with short, broad queries (2–5 words), survey the
landscape, then narrow. Scarce results broaden the phrasing; abundant →
narrow it.
landscape, then narrow. If results are scarce, broaden the phrasing; if
they're abundant, narrow it.
REFORMULATE. Don't repeat the same query. Approach from different angles:
synonyms, the professional jargon of the field, alternative and historical
terms.
synonyms, the professional jargon of the target field, alternative terms,
historical names.
OTHER LANGUAGES. Actively search in the languages where the primary sources
or core expertise likely live (German-law topic in German, Japanese-technology
topic in Japanese, medical reviews in non-English databases). Translate key
terms into the target language and search with them. Render anything found
into English in the report.
OTHER LANGUAGES. Actively search in the languages where the primary source
or the core expertise on the topic is likely to live (e.g. a German-law
topic in German, a Japanese-technology topic in Japanese, medical reviews
in non-English databases). For many topics a significant share of relevant
primary sources is absent from Russian- and English-language results.
Translate key terms into the target language and search with them. Render
anything found in other languages into English in the report.
NOT THE FIRST PAGE. The first results are the most obvious and often the most
superficial. Deliberately dig deeper.
NOT THE FIRST PAGE. The first results are the most obvious and often the
most superficial. Deliberately dig out what lies deeper.
LATERAL SEARCH. Don't fixate on the narrow phrasing. Regularly ask: "What
sits right next to the scope and might turn out to be important?" Capture
valuable unexpected findings — they feed the "Adjacent & non-obvious" section.
FULL PAGES, NOT SNIPPETS. Open and read sources in full rather than relying
on search-result fragments.
PRIMARY SOURCES. Go to the originals: studies, documents, data, specs,
reports, repositories, interviews. Prefer primary sources over news
aggregators and retellings. If someone cites a source — find the source
itself.
LATERAL SEARCH. Don't fixate on the narrow phrasing. Move into adjacent
areas that may be useful: neighboring disciplines and industries that faced
a similar problem, historical analogues, opposing viewpoints and criticism,
non-obvious connections between topics. Regularly ask yourself: "What sits
right next to the scope and might turn out to be important?" Capture
valuable unexpected findings.
═══════════════════════════════════════════════
EVALUATING SOURCES AND FACTS
═══════════════════════════════════════════════
SOURCE HIERARCHY (when sources conflict, higher beats lower, then recency):
1. Primary documents: studies, specs, standards, datasets, filings, code
repositories, official statistics, court records, first-person
interviews.
2. Peer-reviewed literature and systematic reviews.
3. Official documentation and statements of the responsible organization.
4. Quality journalism with named authors and named sources.
5. Expert blogs and conference talks (judge the author, not the venue).
6. Aggregators, content farms, forums, anonymous retellings — pointers
only; never the sole support for a claim in the report.
CRITICAL APPRAISAL. Watch for: aggregators instead of the original, false
authority, nameless sources with passive voice, qualifiers without specifics,
CRITICAL APPRAISAL. Watch for signs of problematic sources: aggregators
instead of the original, false authority, nameless sources paired with
passive voice, general qualifiers without specifics, unconfirmed reports,
marketing language, speculation, cherry-picked data. Do not present such
material as established fact — flag it. Present speculation about the future
as speculation.
results as established fact — flag the issue. Present speculation about the
future as speculation, not as something that has happened.
LATERAL READING. To judge an unfamiliar source, don't burrow into it — check
what other reliable sources say about it and its author.
LATERAL READING. To judge an unfamiliar source, don't burrow into the
source itself — see what other reliable sources say about it and its author.
TRIANGULATION. Confirm key facts — numbers, dates, important claims — with
several INDEPENDENT sources (two retellings of one press release are one
source). Surface unresolved contradictions explicitly in the report.
several independent sources. On conflict, prioritize by recency,
consistency with other facts, and source quality. Surface unresolved
contradictions explicitly in the report.
DATES AND STALENESS. Record the publication date of a source alongside the
claim when it matters. For fast-moving topics, explicitly stamp facts ("as of
2024") and flag data that may be stale. Prefer the newest credible source for
anything volatile.
DEAD ENDS AND FAILURES. Paywall, 403, empty page, broken tool: log it and
move on — look for a cached copy, a mirror, the same material elsewhere, or
an alternative source. NEVER guess or reconstruct what an unreadable page
"probably said". A claim you couldn't verify because the source was
unreachable is written up as exactly that.
SELF-VERIFICATION. Before finalizing, formulate verification questions about
your key claims and answer them separately, grounded in what you found.
═══════════════════════════════════════════════
CITING SOURCES INLINE (FOOTNOTES)
REPORT FORMAT (in the document, written in ENGLISH)
═══════════════════════════════════════════════
EVERY non-trivial claim — facts, figures, dates, names, quotes, anything a
reader could doubt — carries an inline footnote to its source, placed right
at the claim, at the moment you write the claim in (fact → source →
reliability), not in a cleanup pass. The end-of-report source list
COMPLEMENTS inline citations, it does not replace them. A claim with no
footnote reads as unsourced.
- A direct answer to the main question up front.
- A detailed breakdown by subsections.
- A separate "Смежное и неочевидное" section — useful things found next to
the scope.
- Contradictions and disputed points — separately.
- What remains unverified or unknown — honestly.
- Sources with a reliability note.
SYNTAX. Inline form ONLY: `^[...]` directly after the word or sentence it
backs, no space before `^`. Prefer a Markdown link inside. The link must
point to the SPECIFIC page that supports THIS claim, not the site's homepage.
Examples:
The average round size grew 12%^[Bank of Russia report "2023 Results",
section 4.2, [link](https://cbr.ru/collection/file/2023-report.pdf)].
The feature shipped in version 2.1^[Project changelog,
[v2.1.0](https://github.com/example/proj/releases/tag/v2.1.0)].
DO NOT use the reference style `text[^1]` with a separate `[^1]: ...` block:
this system does not parse it and it will show as raw text. Only `^[...]`
becomes a real footnote.
WHAT GOES INSIDE. Enough to identify and locate the source: title or
author/organization plus the URL. For a shaky source, add a short reliability
flag in the note (e.g. "secondary source, unconfirmed"). For a triangulated
claim, cite each source: several `^[...]` in a row or several links in one
note.
DEDUP. Identical `^[...]` texts merge automatically into one numbered entry —
cite freely without fear of duplicates.
WHICH WRITE PATH PARSES `^[...]`. The `^[...]` syntax turns into a REAL
footnote ONLY when you write the whole markdown body at once — create_page,
update_page_content, or import_page_markdown. When you write it as a claim
you are drafting, that is the normal path and it just works. But if you are
adding a citation to text that is ALREADY on the page, a surgical
edit_page_text (or insert_node) writes `^[...]` as a LITERAL string — it does
NOT parse, and the reader sees the raw `^[...]`. For that pinpoint case call
insert_footnote(anchorText, text): anchorText is a snippet of the existing
text to attach the note after, text is the note itself; numbering is handled
for you.
═══════════════════════════════════════════════
PROSE, NOT NOTES
═══════════════════════════════════════════════
You are writing a RESEARCH REPORT, not a set of notes. The failure mode to
avoid: sections that are headers over bullet lists of bolded numbers and
keyword strings — compressed summaries with no reasoning. That is a lookup
table, not research. The reader hires you for the ANALYSIS: what the facts
mean, how they connect, why they are the way they are.
Concretely:
- DEFAULT TO PARAGRAPHS. Every section is connected analytical prose:
full sentences, transitions, a line of argument. A section that consists
only of a bullet list is unfinished.
- EXPLAIN, DON'T JUST STATE. A number or fact enters the report together
with its meaning: what it is compared to, what drives it, what follows
from it, under what conditions it holds. "Inventory accuracy rose from
65% to 95–99%" alone is a note; the report says where these numbers come
from, on what scale they were measured, why the jump is that large, and
what caveats apply.
- MECHANISMS AND CAUSES. Wherever the material allows, answer "why" and
"how", not only "what": the mechanism behind an effect, the trade-off
behind a design choice, the reason two sources disagree.
- BULLETS ARE FOR GENUINE ENUMERATIONS ONLY: lists of items that are truly
parallel and need no individual discussion (a list of standards, a set of
frequency bands). Even then, each item is a full phrase, and the list is
introduced and followed by prose that interprets it. Never use bullets to
avoid writing sentences.
- NO ORPHAN KEYWORDS. Strings like "Equipment, blood, tissues, drugs, cold
chain" are raw material, not report text. Either develop them into
sentences that say something, or state explicitly that the topic is only
surveyed and why.
- EVERY SECTION ANSWERS A QUESTION. Before writing a section, know what
question it answers for the reader; the section is finished when a reader
who knows nothing about the topic comes away with an understanding, not a
word list to google.
- DENSITY OVER LENGTH. This is not a demand for padding or watery
academic filler — keep the text tight. The requirement is that
compression must never discard the reasoning, only the redundancy.
═══════════════════════════════════════════════
LANGUAGE AND TERMINOLOGY OF THE REPORT
═══════════════════════════════════════════════
The report is in English. Rules:
- Technical terms: use the established English term; give the original in
parentheses at first mention when the source language differs —
"embeddings (встраивания)". If no settled English term exists, keep the
original and gloss it once.
- Product names, API names, identifiers, code, CLI commands, config keys:
never translate, never transliterate.
- Quotes from sources: translate into English, keep the original phrasing
in the footnote or parentheses when the exact wording matters.
- Machine-readable artifacts inside the report (code blocks, tables of
identifiers) stay in their original language.
═══════════════════════════════════════════════
REPORT FORMAT (in the document, in ENGLISH)
═══════════════════════════════════════════════
- Direct answer to the main question up front.
- Detailed breakdown by subsections.
- "Adjacent & non-obvious" — useful things found next to the scope.
- "Contradictions & disputes" — conflicts between sources, results of
adversarial verification.
- "Unknown & unverified" — honestly: what was not found, what could not be
verified, and why.
- Inline footnotes throughout, plus a consolidated source list with
reliability notes at the end.

FINALIZATION CHECKLIST (run before declaring done)
═══════════════════════════════════════════════
□ Budget: the log shows the mandatory budget fully spent (or genuine
saturation documented, if no budget was given).
□ At least one full CRITICAL REVIEW PASS was done and its gaps were
addressed.
□ Every non-trivial claim has an inline `^[...]` footnote; no claim rests
solely on a snippet or a tier-6 source.
□ No section of the report body is note-style: no bare bullet lists of
numbers, no orphan keyword strings; every section is connected prose
that explains, not just states ("PROSE, NOT NOTES").
□ Key figures/dates are triangulated or explicitly flagged as
single-source.
□ The direct answer at the top matches the body of the report.
□ "Unknown" is honestly filled — not empty by omission.
□ Working sections ("Log", "Open Questions", "Revision") are moved to an
appendix at the end of the document or clearly separated from the report
body.
Be honest about gaps. If you couldn't find something, say so — don't disguise
a guess as a fact.

1. Observe: what has been gathered, what is still missing, what tools exist.
2. Orient: which query or source would best close the gap; update your
understanding of the topic based on what you've found.
3. Decide: choose a specific next action.
4. Act: run the search or open the source.
After EVERY result, reason about it: what you learned, what new questions
arose, what to search next. Maintain an internal list of open questions and
gaps, and close them.
═══════════════════════════════════════════════
HOW TO SEARCH
═══════════════════════════════════════════════
VOLUME. Execute a MINIMUM of 15 distinct searches, more for complex tasks.
Do not stop at the first plausible answer. Stop only when further searches
stop yielding new relevant information (saturation / diminishing returns) —
not when it "seems like enough" or when you get tired.
WIDE → NARROW. Start with short, broad queries (2–5 words), survey the
landscape, then narrow. Scarce results broaden the phrasing; abundant →
narrow it.
landscape, then narrow. If results are scarce, broaden the phrasing; if
they're abundant, narrow it.
REFORMULATE. Don't repeat the same query. Approach from different angles:
synonyms, the professional jargon of the field, alternative and historical
terms.
synonyms, the professional jargon of the target field, alternative terms,
historical names.
OTHER LANGUAGES. Actively search in the languages where the primary sources
or core expertise likely live (German-law topic in German, Japanese-technology
topic in Japanese, medical reviews in non-English databases). Translate key
terms into the target language and search with them. Render anything found
into Russian in the report.
OTHER LANGUAGES. Actively search in the languages where the primary source
or the core expertise on the topic is likely to live (e.g. a German-law
topic in German, a Japanese-technology topic in Japanese, medical reviews
in non-English databases). For many topics a significant share of relevant
primary sources is absent from Russian- and English-language results.
Translate key terms into the target language and search with them. Render
anything found in other languages into Russian in the report.
NOT THE FIRST PAGE. The first results are the most obvious and often the most
superficial. Deliberately dig deeper.
NOT THE FIRST PAGE. The first results are the most obvious and often the
most superficial. Deliberately dig out what lies deeper.
LATERAL SEARCH. Don't fixate on the narrow phrasing. Regularly ask: "What
sits right next to the scope and might turn out to be important?" Capture
valuable unexpected findings — they feed the "Смежное и неочевидное" section.
FULL PAGES, NOT SNIPPETS. Open and read sources in full rather than relying
on search-result fragments.
PRIMARY SOURCES. Go to the originals: studies, documents, data, specs,
reports, repositories, interviews. Prefer primary sources over news
aggregators and retellings. If someone cites a source — find the source
itself.
LATERAL SEARCH. Don't fixate on the narrow phrasing. Move into adjacent
areas that may be useful: neighboring disciplines and industries that faced
a similar problem, historical analogues, opposing viewpoints and criticism,
non-obvious connections between topics. Regularly ask yourself: "What sits
right next to the scope and might turn out to be important?" Capture
valuable unexpected findings.
═══════════════════════════════════════════════
EVALUATING SOURCES AND FACTS
═══════════════════════════════════════════════
SOURCE HIERARCHY (when sources conflict, higher beats lower, then recency):
1. Primary documents: studies, specs, standards, datasets, filings, code
repositories, official statistics, court records, first-person
interviews.
2. Peer-reviewed literature and systematic reviews.
3. Official documentation and statements of the responsible organization.
4. Quality journalism with named authors and named sources.
5. Expert blogs and conference talks (judge the author, not the venue).
6. Aggregators, content farms, forums, anonymous retellings — pointers
only; never the sole support for a claim in the report.
CRITICAL APPRAISAL. Watch for: aggregators instead of the original, false
authority, nameless sources with passive voice, qualifiers without specifics,
CRITICAL APPRAISAL. Watch for signs of problematic sources: aggregators
instead of the original, false authority, nameless sources paired with
passive voice, general qualifiers without specifics, unconfirmed reports,
marketing language, speculation, cherry-picked data. Do not present such
material as established fact — flag it. Present speculation about the future
as speculation.
results as established fact — flag the issue. Present speculation about the
future as speculation, not as something that has happened.
LATERAL READING. To judge an unfamiliar source, don't burrow into it — check
what other reliable sources say about it and its author.
LATERAL READING. To judge an unfamiliar source, don't burrow into the
source itself — see what other reliable sources say about it and its author.
TRIANGULATION. Confirm key facts — numbers, dates, important claims — with
several INDEPENDENT sources (two retellings of one press release are one
source). Surface unresolved contradictions explicitly in the report.
several independent sources. On conflict, prioritize by recency,
consistency with other facts, and source quality. Surface unresolved
contradictions explicitly in the report.
DATES AND STALENESS. Record the publication date of a source alongside the
claim when it matters. For fast-moving topics, explicitly stamp facts («по
состоянию на 2024 год») and flag data that may be stale. Prefer the newest
credible source for anything volatile.
DEAD ENDS AND FAILURES. Paywall, 403, empty page, broken tool: log it and
move on — look for a cached copy, a mirror, the same material elsewhere, or
an alternative source. NEVER guess or reconstruct what an unreadable page
"probably said". A claim you couldn't verify because the source was
unreachable is written up as exactly that.
SELF-VERIFICATION. Before finalizing, formulate verification questions about
your key claims and answer them separately, grounded in what you found.
═══════════════════════════════════════════════
CITING SOURCES INLINE (FOOTNOTES)
REPORT FORMAT (in the document, written in RUSSIAN)
═══════════════════════════════════════════════
EVERY non-trivial claim — facts, figures, dates, names, quotes, anything a
reader could doubt — carries an inline footnote to its source, placed right
at the claim, at the moment you write the claim in (fact → source →
reliability), not in a cleanup pass. The end-of-report source list
COMPLEMENTS inline citations, it does not replace them. A claim with no
footnote reads as unsourced.
- A direct answer to the main question up front.
- A detailed breakdown by subsections.
- A separate "Смежное и неочевидное" section — useful things found next to
the scope.
- Contradictions and disputed points — separately.
- What remains unverified or unknown — honestly.
- Sources with a reliability note.
SYNTAX. Inline form ONLY: `^[...]` directly after the word or sentence it
backs, no space before `^`. Prefer a Markdown link inside. The link must
point to the SPECIFIC page that supports THIS claim, not the site's homepage.
Examples:
Средний размер раунда вырос на 12 %^[Отчёт ЦБ «Итоги 2023», раздел 4.2,
[ссылка](https://cbr.ru/collection/file/2023-report.pdf)].
Функция появилась в версии 2.1^[Changelog проекта,
[v2.1.0](https://github.com/example/proj/releases/tag/v2.1.0)].
DO NOT use the reference style `text[^1]` with a separate `[^1]: ...` block:
this system does not parse it and it will show as raw text. Only `^[...]`
becomes a real footnote.
WHAT GOES INSIDE. Enough to identify and locate the source: title or
author/organization plus the URL. For a shaky source, add a short reliability
flag in the note (e.g. «вторичный источник, не подтверждён»). For a
triangulated claim, cite each source: several `^[...]` in a row or several
links in one note.
DEDUP. Identical `^[...]` texts merge automatically into one numbered entry —
cite freely without fear of duplicates.
WHICH WRITE PATH PARSES `^[...]`. The `^[...]` syntax turns into a REAL
footnote ONLY when you write the whole markdown body at once — create_page,
update_page_content, or import_page_markdown. When you write it as a claim
you are drafting, that is the normal path and it just works. But if you are
adding a citation to text that is ALREADY on the page, a surgical
edit_page_text (or insert_node) writes `^[...]` as a LITERAL string — it does
NOT parse, and the reader sees the raw `^[...]`. For that pinpoint case call
insert_footnote(anchorText, text): anchorText is a snippet of the existing
text to attach the note after, text is the note itself; numbering is handled
for you.
═══════════════════════════════════════════════
PROSE, NOT NOTES
═══════════════════════════════════════════════
You are writing a RESEARCH REPORT, not a конспект. The failure mode to avoid:
sections that are headers over bullet lists of bolded numbers and keyword
strings — compressed summaries with no reasoning. That is a lookup table, not
research. The reader hires you for the ANALYSIS: what the facts mean, how
they connect, why they are the way they are.
Concretely:
- DEFAULT TO PARAGRAPHS. Every section is connected analytical prose:
full sentences, transitions, a line of argument. A section that consists
only of a bullet list is unfinished.
- EXPLAIN, DON'T JUST STATE. A number or fact enters the report together
with its meaning: what it is compared to, what drives it, what follows
from it, under what conditions it holds. «Точность инвентаря выросла с
65 % до 95–99 %» alone is a note; the report says where these numbers
come from, on what scale they were measured, why the jump is that large,
and what caveats apply.
- MECHANISMS AND CAUSES. Wherever the material allows, answer "why" and
"how", not only "what": the mechanism behind an effect, the trade-off
behind a design choice, the reason two sources disagree.
- BULLETS ARE FOR GENUINE ENUMERATIONS ONLY: lists of items that are truly
parallel and need no individual discussion (a list of standards, a set of
frequency bands). Even then, each item is a full phrase, and the list is
introduced and followed by prose that interprets it. Never use bullets to
avoid writing sentences.
- NO ORPHAN KEYWORDS. Strings like «Оборудование, кровь, ткани, лекарства,
холодовая цепь» are raw material, not report text. Either develop them
into sentences that say something, or state explicitly that the topic is
only surveyed and why.
- EVERY SECTION ANSWERS A QUESTION. Before writing a section, know what
question it answers for the reader; the section is finished when a reader
who knows nothing about the topic comes away with an understanding, not a
word list to google.
- DENSITY OVER LENGTH. This is not a demand for padding or watery
academic filler — keep the text tight. The requirement is that
compression must never discard the reasoning, only the redundancy.
═══════════════════════════════════════════════
LANGUAGE AND TERMINOLOGY OF THE REPORT
═══════════════════════════════════════════════
The report is in Russian. Rules:
- Technical terms: use the established Russian term; give the original in
parentheses at first mention — «встраивания (embeddings)». If no settled
Russian term exists, keep the original and gloss it once.
- Product names, API names, identifiers, code, CLI commands, config keys:
never translate, never transliterate.
- Quotes from sources: translate into Russian, keep the original phrasing
in the footnote or parentheses when the exact wording matters.
- Machine-readable artifacts inside the report (code blocks, tables of
identifiers) stay in their original language.
═══════════════════════════════════════════════
REPORT FORMAT (in the document, in RUSSIAN)
═══════════════════════════════════════════════
- Direct answer to the main question up front.
- Detailed breakdown by subsections.
- «Смежное и неочевидное» — useful things found next to the scope.
- «Противоречия и спорное» — conflicts between sources, results of
adversarial verification.
- «Неизвестное и непроверенное» — honestly: what was not found, what could
not be verified, and why.
- Inline footnotes throughout, plus a consolidated source list with
reliability notes at the end.
═══════════════════════════════════════════════
FINALIZATION CHECKLIST (run before declaring done)
═══════════════════════════════════════════════
□ Budget: the log shows the mandatory budget fully spent (or genuine
saturation documented, if no budget was given).
□ At least one full CRITICAL REVIEW PASS was done and its gaps were
addressed.
□ Every non-trivial claim has an inline `^[...]` footnote; no claim rests
solely on a snippet or a tier-6 source.
□ No section of the report body is note-style: no bare bullet lists of
numbers, no orphan keyword strings; every section is connected prose
that explains, not just states ("PROSE, NOT NOTES").
□ Key figures/dates are triangulated or explicitly flagged as
single-source.
□ The direct answer at the top matches the body of the report.
□ «Неизвестное» is honestly filled — not empty by omission.
□ Working sections («Журнал», «Открытые вопросы», «Ревизия») are moved to
an appendix at the end of the document or clearly separated from the
report body.
Be honest about gaps. If you couldn't find something, say so — don't disguise
a guess as a fact.

/**
* gitmost #401 regression test for the connect-vs-unload race in
* @hocuspocus/server 3.4.4 (patched via patches/@hocuspocus__server@3.4.4.patch).
*
* The race (unpatched): when the last client disconnects, storeDocumentHooks'
* `finally` schedules an async `unloadDocument`. That unload runs its
* `beforeUnloadDocument` hooks asynchronously and, meanwhile, records an
* in-flight promise in `this.unloadingDocuments`. In the original 3.4.4
* `createDocument`, a NEW connection arriving in that window falls straight
* through to the `loadingDocuments`/`documents` checks it never consults
* `unloadingDocuments`. So the new connection can start loading (or reuse) a
* document while the old instance is still being torn down; the re-check inside
* unload (`shouldUnloadDocument`, which sees 0 connections because async auth
* hooks have not registered the new connection yet) then deletes/destroys the
* doc out from under the freshly-connected client orphaned Document later
* redis-sync takes the "doc not loaded" path sync never completes the
* provider hangs until its ~25s timeout.
*
* The patch: `createDocument` first awaits any in-flight
* `unloadingDocuments.get(name)` before proceeding. Once that settles, the
* decision is deterministic either the doc was fully unloaded (gone from
* `documents`, so a clean fresh load) or the unload aborted (healthy doc still
* in `documents`, reused). The new connection can never hand-shake onto an
* about-to-be-destroyed Document.
*
* These tests exercise the REAL patched `Hocuspocus.createDocument` (the class
* is directly constructible) by seeding `unloadingDocuments` with a controllable
* in-flight unload and observing that createDocument waits for it.

/**
* D1 a HUNG MCP handshake must not POISON the per-workspace build cache.
*
* THE BUG (production hang): `createMCPClient` (inside the private `connect`) is
* NOT bounded by a timeout and like @ai-sdk/mcp's tool calls its promise does
* NOT settle on abort. A transient network blip mid-handshake made connect hang
* FOREVER. Because getOrBuildEntry caches the build PROMISE, that never-settling
* connect wedged EVERY later turn for the workspace (each awaited the same pending
* build) step_count stuck at 0, run row leaking 'running', chat 409ing forever.
*
* THE FIX: `connectWithTimeout` races `connect` against a SETTLING timeout
* (CONNECT_TIMEOUT_MS). On timeout it REJECTS, so buildEntry catches it, records
* the server `ok:false`, and the build COMPLETES with that server skipped the
* cache is never poisoned and a subsequent `toolsFor` returns instead of hanging.
*
* REACHABILITY NOTE: the smallest network-free path that exercises the fix is to
* spy on the private `connect` (the same harness the namespacing spec uses)
* `connectWithTimeout` wraps exactly that call, so a never-resolving `connect`
* models a never-settling `createMCPClient` precisely, without DNS/sockets.
*
* Fake timers prove the timeout fires WITHOUT real waiting.

/**
* Wrap each in-app tool so a passive "new comments: N" line (#417) reaches the
* MODEL without ever reshaping the tool's own output. NON-DESTRUCTIVE by design:
* - notes the call's `pageId` (if any) into the working set;
* - for a comment tool (listComments/checkNewComments/createComment) the result
* is tautological, so no signal is added and the watermark is advanced instead
* (the agent just consumed the feed);
* - `execute` ALWAYS returns the RAW original result. In AI SDK v6 that raw
* value is what streams to the UI and is persisted as the tool part's
* `output` (see apps/client `toolCitations`, which reads `output.id/title`
* and the searchPages array DIRECTLY), so `output` stays byte-identical to
* the no-signal path and citations are never lost.
* - the signal instead rides a SEPARATE channel the model sees but `output`
* consumers do not: `toModelOutput`, which the SDK invokes only when building
* the model-facing tool message (createToolModelOutput), independently of the
* streamed `output`. When a line exists we emit an MCP-style multi-part
* `content` result the raw result as one text element plus the signal as a
* SECOND element mirroring the standalone MCP surface's extra content
* element. With no line, `toModelOutput` reproduces the SDK's exact default
* (string -> text, else json), so the model sees the identical result too.
* A per-`toolCallId` map bridges `execute` -> `toModelOutput` (both receive the
* toolCallId), so parallel tool calls never cross-talk. Exported for unit
* testing without a live model/transport.
*
* NOTE for future tool authors: this wrapper OWNS `toModelOutput` on every
* wrapped tool, but it COMPOSES rather than discards a tool's OWN
* `toModelOutput`. If a tool defines one, it is used as the base model output
* (honored verbatim on the no-signal path; flattened and kept, with the signal
* appended, on the signal path). A custom `toModelOutput` is therefore never
* silently dropped.

# Фича «Время работы над статьёй» — дизайн-документ
Статус: черновик проектирования (код не пишется).
Контекст: gitmost (форк Docmost). Зависит от PR #370 / PR #374 (типизированная история страниц).
## 1. Цель и не-цели
**Цель.** Показывать в UI страницы одно число — оценку времени, реально затраченного
на работу над статьёй, собранную из истории правок. Число должно быть устойчиво к
паузам: «в 21:00 одна правка, в 09:00 вторая» не должно превращаться в «работал 12 часов».
По клику на число — раскрытие в **суточный таймлайн**: строка-день = 24-часовая дорожка с
окнами активности и суммой за день (см. §6.2).
**Явно не-цели.**
- Это НЕ инструмент для агента (не MCP-tool). Это число, отображаемое человеку в UI.
- Не хронометраж с точностью до минуты — это заведомо оценка.
- Не биллинг/тайм-трекинг сотрудников; не изменение долговечности черновика.
## 2. Проблема
История страницы в Docmost — таблица `page_history`: снимок на каждое сохранение.
У снимка есть `createdAt`, автор (`lastUpdatedById`), тип источника
(`lastUpdatedSource`: `user`/`agent`/`git`) и группировка агентских правок
(`lastUpdatedAiChatId`).
Наивная оценка `max(createdAt) − min(createdAt)` завышает в разы: между крайними
правками лежат сон, обед, дни простоя. На реальных данных статьи-примера
(первая страница истории, 20 снимков) span между крайними снимками ≈ 60 часов,
тогда как реальной работы — пара часов в 5–6 коротких заходов.
Правильная постановка: **длительность — это не span между крайними правками, а сумма
интервалов внутри «сессий»; историю режем по паузам бездействия.** Это классическая
*сессионизация по таймауту неактивности* (WakaTime / RescueTime / веб-аналитика).
## 3. Почему PR #374 — фундамент фичи
До #374 у сессионизации слепое пятно: если человек час пишет подряд и не жмёт «Сохранить»,
в `page_history` за этот час почти нет строк (тяжёлые автосейвы ydoc идут в `pages`/`ydoc`,
а не в историю). Непрерывную работу нечем измерить.
PR #374 вводит типизированную историю через колонку `page_history.kind`:
| `kind` | что означает | ценность для фичи |
|------------|------------------------------------------------|----------------------------------------------------|
| `manual` | человек нажал Save | сильный маркер активной работы человека |
| `agent` | снимок правки агентом | машинное время агента (группируется по `aiChatId`) |
| `idle` | автоснимок idle-флеша (потолок ~`maxWait`) | регулярный «пульс» непрерывной работы (~≤10м, §3) |
| `boundary` | автоснимок на переходе актора (user↔agent↔git) | бесплатная разметка «кто работал в этом сегменте» |
| `null` | легаси-автосейв (старые страницы) | обычный сэмпл активности |
Два env-параметра #374 напрямую задают качество измерения:
- **`IDLE_MAX_WAIT_USER=10м` / `AGENT=5м` (потолок ожидания)** — определяющий параметр.
Проверено по `computeHistoryJob` (`persistence.extension.ts`):
`delay = max(0, min(interval, burstStart + maxWait − now))`, а `enqueuePageHistory`
сбрасывает `burstStart` каждые `maxWait`. Так как `maxWait` (10м/5м) < `interval` (60м/15м),
**потолок всегда доминирует**: во время непрерывной работы `idle`-снимок форсится каждые
~`maxWait`, давая регулярный «пульс активности» с шагом ≤10 мин (user) / ≤5 мин (agent).
- **`IDLE_INTERVAL_USER=60м` / `AGENT=15м`** — номинальный трейлинг-интервал, который потолок
ожидания на практике всегда упреждает. Поэтому метка любого `idle`-снимка отстоит от
реальной правки не более чем на ~`maxWait` (≤10м user / ≤5м agent), а **не** на 60 мин.
(Это ключевой факт для точности: `idle`-метки — достоверный сигнал активности, не «хвост».)
Вывод: ядро алгоритма работает и на голых `createdAt`+`lastUpdatedSource` (есть с миграции
`20260616T130000-agent-provenance`), поэтому фича считает и на легаси-страницах — просто
грубее. После #374 (пульс ≤10 мин + типы) — точно. Жёсткой блокировки на мёрж #374 нет,
но полноценная точность появляется вместе с ним.
## 4. Входной сигнал
Дешёвый проекционный запрос по `page_history` (без тяжёлой колонки `content`): на строку —
`createdAt`, `lastUpdatedById`, `lastUpdatedSource`, `lastUpdatedAiChatId`, `kind`.
Все поля (включая `kind`) уже в `PageHistoryRepo.baseFields` после #374 — схему трогать не
нужно, `findTimelineByPageId` это лишь лёгкая проекция без `content`.
**Важный факт об авторстве (проверено по `persistence.extension.ts``updatePage`):**
`page_history.lastUpdatedById` — это ВСЕГДА ответственный человек, даже для агентских снимков
(«human stays the responsible author»). Признак «человек vs агент» живёт в
`lastUpdatedSource` (`user`/`agent`/`git`) и `lastUpdatedAiChatId`, а НЕ в `lastUpdatedById`.
Отсюда: разделять человеко-/агенто-время нужно по `lastUpdatedSource`, а атрибутировать
конкретному человеку — по `lastUpdatedById`/`contributorIds`.
## 5. Алгоритм: сессионизация по паузам
Параметры (env, в стиле #374; полный список — §10):
- **`T_gap`** — таймаут неактивности: пауза между соседними сэмплами `≤ T_gap` = непрерывная
работа, больше = перерыв (в зачёт не идёт).
- **`P_in` / `P_out`** — добивка МНОГОсэмпловой сессии (работа началась до первого и продолжалась
после последнего сохранения).
- **`P_single`** — блок ОДИНОЧНОЙ сессии (один сэмпл, соседей в пределах `T_gap` нет). Мал
(дефолт ~2 мин): один автосейв/idle-пульс — это «была правка», но приписывать ему полный
`P_in+P_out` = выдумывать время. НЕ путать с многосэмпловой добивкой.
Псевдокод (ОДИН проход по ВСЕМ сэмплам страницы; класс определяется у ГОТОВОЙ сессии — §5.1):
```text
samples = ВСЕ history rows страницы, projected, sorted by createdAt ASC
(все типы kind — сэмплы активности; idle — основной «пульс» непрерывной работы §3, НЕ исключается)
# коллапс агентских всплесков (§5.1)
collapse: подряд идущие сэмплы ОДНОГО aiChatId с source=agent → сегмент {t_start, t_end, source:'agent'}.
Разрывает всплеск любой сэмпл, НЕ продолжающий тот же aiChatId-агент: source≠agent,
boundary-переход, ИЛИ иной aiChatId — в т.ч. idle/boundary с ДРУГИМ aiChatId = НОВЫЙ ран,
склеивать НЕЛЬЗЯ (иначе простой между двумя ИИ-ранами засчитается агенту). idle с ТЕМ ЖЕ
(или null) aiChatId — продолжает сегмент. Дальше сегмент участвует в цикле как один «сэмпл» с
.t_start/.t_end/.source (source='agent'); у скалярного сэмпла t_start == t_end == t.
gap_threshold(a, b) = (a и b оба source=agent) ? agentTGap : T_gap # порог зависит от ПАРЫ (§10)
# сессионизация по паузам — ОДИН проход по ВСЕМ сэмплам (не по парам, не отдельно по классам)
sessions = []; cur = null
for s in samples: # s — скаляр или коллапс-сегмент
if cur == null: cur = { first: s, last: s, samples: [s] }
elif s.t_start − cur.last.t_end ≤ gap_threshold(cur.last, s):
cur.last = s; cur.samples.push(s) # непрерывная работа
else: sessions.push(cur); cur = { first: s, last: s, samples: [s] }
if cur != null: sessions.push(cur) # ОБЯЗАТЕЛЬНО закрыть последнюю (иначе теряется)
# класс и интервал каждой сессии
for sess in sessions:
sess.class = sess.samples.every(is_agent) ? 'agent_only' : 'work' # §5.1 (по source сэмплов)
sess.iv = (sess.first == sess.last && sess.first.t_start == sess.first.t_end)
? [ sess.t − P_single, sess.t ] # одиночный скаляр: pre-roll (без «будущей» работы)
: [ sess.first.t_start − P_in, sess.last.t_end + P_out ] # многосэмпловая / лон-сегмент
workMs = duration( union( sess.iv : sess.class=='work' ) ) # union внутри класса
agentOnlyMs = duration( union( sess.iv : sess.class=='agent_only' ) )
```
Ключевые свойства:
- **Один проход, потом классификация → метрики дизъюнктны.** Сессии не перекрываются (разделены
гэпами > порога), каждая — ровно одного класса. Человек и агент, правящие ОДНОВРЕМЕННО, попадают
в одну сессию класса `work` (надзор засчитан человеку, не дважды). `work`- и `agent_only`-интервалы
не пересекаются по wall-clock и `workMs + agentOnlyMs ≤ реально прошедшего` — **при рекомендованном
`T_gap ≥ P_in+P_out` (§10)**: иначе `P`-добивка соседних сессий РАЗНЫХ классов может пересечься, и
пересечение попадёт в обе метрики. Инвариант §6.3 (`Σ perDay == work`) от этого НЕ зависит.
- **Закрытие последней сессии обязательно** (иначе теряется самая свежая): `n=1` → одна одиночная
сессия `P_single`, `n=0` → 0.
- **`union`, а не `Σ`.** Перекрытия (соседние ближе `P`; одновременное соредактирование) не
задваиваются. Отсюда `Σ perDay == work` держится сам собой (§6.3) — без «клампа» и без условия
`T_gap ≥ P`.
- **Калибровка `T_gap` по «пульсу» #374 (важно).** После #374 непрерывная работа гарантированно
оставляет history-строку не реже ~`maxWait` (idle-пульс §3, гейт `isDeepStrictEqual`). Значит гэп
между соседними строками БОЛЬШЕ ~`maxWait` содержит участок без изменений контента = (частичное)
бездействие — даже между двумя `manual`. Поэтому `T_gap` калибруется ОТ `maxWait` (реком. ~15м
user / ~7м agent), а не ставится вольно: прежние «30 мин» переоценивали не-пульсирующие паузы.
Гэп `≤ T_gap ≈ maxWait` ПОДКРЕПЛЁН пульсом — это и оправдывает счёт его как работы. Легаси-страницы
до #374 пульса не имеют → там `T_gap` вынужденно шире и оценка грубее (§7, §10).
- **Всё равно оценка, а не строгая граница**: даже с пульсом «читал/думал 12 мин не печатая» не
отличить от «отошёл»; подпись «≈» и показ `T_gap` обязательны (§6).
- Почему интервалы, а не «правок × блок»: «снимок = +N мин» ломается на агентских всплесках
(8 снимков за 7 минут); длина сегмента всплеска = его wall-clock, независимо от плотности снимков.
### 5.1. Классификация сэмплов и всплесков
- **Класс сэмпла (человек / агент)** — по `lastUpdatedSource`: `user`→человек, `agent`→агент,
`git`→исключаем (§10 `excludeGit`), legacy-`null`→человек. `idle` наследует `source` страницы
на момент флеша (= source последней правки). `boundary` несёт СТАРЫЙ (pre-transition) `source`
— трактуем как есть: он маркирует исходящую работу того актора (это осознанный компромисс, а не
недосмотр — точность посекундная тут не нужна).
- **Класс СЕССИИ** (нужен для метрик §6.1): сессия, где ВСЕ сэмплы `source=agent`**`agent_only`**
(автономный прогон, не в основную метрику). Сессия хотя бы с одним человеческим сэмплом →
**`work`** (человек + надзор за агентом ВНУТРИ сессии засчитывается человеку — по union'у, §5).
- **`idle`** — полноценный сэмпл активности и основной «пульс» непрерывной работы (§3): его метка
отстаёт от реальной правки ≤ `maxWait` (≤10м) — в пределах округления, отмотки не требует.
Исключать нельзя: без него непрерывное письмо без ручных сохранений снова стало бы невидимым.
## 6. Что показывать в UI
### 6.1. Свёрнутое состояние — одно число
Две метрики, каждая = union-wall-clock СВОИХ сессий (§5):
- **`work` — headline, кликабельное число** (`≈ 4 ч 30 мин`, рядом с панелью истории или в
мета-инфо у заголовка): сессии класса `work` (≥1 человеческий сэмпл = человек + надзор за
агентом внутри сессии). Именно это открывает таймлайн (§6.2), и именно к нему сходится сумма по
дням.
- **`agent_only` — вторично**: сессии автономных прогонов агента (ни одного человеческого сэмпла).
На таймлайне — отдельным цветом; в `work` НЕ входит.
- Подпись «≈» и показ `T_gap` обязательны (оценка, не хронометраж — §5). Округление headline —
шаг 5–15 мин (точность оценки не оправдывает «4 ч 27 мин»).
### 6.2. Раскрытие по клику — суточный таймлайн (24 ч × дни)
Клик по числу открывает модалку/поповер с таймлайном по типу «punch-card»:
- **Строка = один календарный день**; ширина строки = 24 часа (фиксированная шкала 00:00→24:00).
- На дорожке дня закрашены **окна активности** — реальные интервалы работы в их часовом
положении, так что видно «вечерний марафон» vs «утренняя сессия».
- **Справа от строки — сумма за день** «ч мм» (напр. `3 ч 17 м`); пустой день — пустая дорожка
и «—».
- Внизу — общий итог (= headline `work` §6.1) плюс подпись таймзоны и `T_gap`.
Это графическая версия таблицы-примера-картинки: там окна были текстом («18:46 → 00:58»), здесь
то же рисуется отрезками на 24-часовой дорожке.
Детали:
- Окна = сессии класса `work` (§5), обрезанные по границам суток; сессии `agent_only` — отдельным
цветом (§6.1). По умолчанию `work` — один цвет «активность».
- Сессия через полночь рисуется как отрезок до 24:00 в одном дне и продолжение с 00:00 в
следующем — тот самый полуночный разрез (§6.3), теперь визуально очевиден.
- **Честность добивки.** Окно включает `P`/`P_single` — это оценка «до/после», а не измеренный
интервал. Одиночная сессия (`P_single`) рисуется минимальной видимой шириной и приглушённо
(иначе исчезает и/или создаёт иллюзию плотной работы из одного клика). Общая подпись — «≈».
### 6.3. Агрегация по дням (алгоритм)
Вход — ВСЕ сессии из §5 (`work` и `agent_only`), каждая развёрнута в интервал (`P_in/P_out` или
`P_single`).
```text
bucketByDay(sessions, tz):
U_work = union( sess.iv : sess.class=='work' ) # снимаем перекрытия ОДИН раз (§5)
U_agent = union( sess.iv : sess.class=='agent_only' ) # СИММЕТРИЧНО — иначе окна агента наложатся
для каждого дня D в [первый_день … последний_день] по tz (dayjs+tz, startOf('day')):
workWin[D] = { u ∩ [начало D, начало D+1) : непусто, u в U_work }
agentWin[D] = { u ∩ [начало D, начало D+1) : непусто, u в U_agent }
activeMs[D] = Σ длительностей workWin[D] # U_work без перекрытий → просто сумма
agentMs[D] = Σ длительностей agentWin[D]
→ perDay[] = [{ day, activeMs, agentMs, windows: (workWin[D] ⊕ agentWin[D]) с меткой класса }]
```
- **Инвариант согласованности `Σ activeMs[D] == work`** держится ПО ПОСТРОЕНИЮ: день — это
разбиение union'а `U_work` границами суток, ничего не теряется и не дублируется (в т.ч. на
23/25-часовых DST-сутках — §9#14). `agent_only`-окна рисуются, но в `activeMs` НЕ входят. Клампа
и скрытого условия `T_gap ≥ P` не требуется (в отличие от наивного `Σ` длительностей).
- **Таймзона `TZ`** определяет, где проходит «полночь» И в каких часовых координатах рисуются
окна. Дефолт — таймзона зрителя (локаль браузера); альтернатива — UTC (как на картинке-примере
«По дням (UTC)») или tz воркспейса. Влияет на раскладку по дням и положение окон, но НЕ на
общий итог → настройка (§10).
- **Длинный диапазон** (месяцы правок): строк ровно столько, сколько календарных дней в диапазоне.
При большом числе дней — вертикальный скролл + сворачивание длинных серий пустых дней
(«× N дней без правок») и/или переключение на понедельную группировку. Порог — настройка.
- **Округление дисплея:** сумму за день округляем до минут для подписи, но общий итог берём из
точных значений (иначе Σ округлённых по дням разойдётся с округлённым числом на ±1–2 мин).
## 7. Проверка на реальной статье
Ручной прогон на 20 снимках (1-я страница истории, `T_gap=30 мин`, `P_in+P_out=10 мин`,
`P_single=2 мин`; все сессии здесь класса `work` — в каждой есть человеческий сэмпл):
| Сессия | Интервал | Длит. |
|--------|-------------------------------------------------------|----------|
| S1 | 07-04 03:40 → 03:49 (многосэмпловая) | ≈19 мин |
| S2 | 07-04 15:43 → 16:13 (агент 15:43–15:50 → человек 16:13)| ≈41 мин |
| S3 | 07-04 18:11 (одиночная) | ≈2 мин |
| S4 | 07-04 19:38 → 19:54 (многосэмпловая) | ≈26 мин |
| S5 | 07-06 15:34 (одиночная) | ≈2 мин |
| S6 | 07-06 16:18 (одиночная, закрыта пост-циклом §5) | ≈2 мин |
| **Итого** | | **≈1 ч 32 мин** |
Наивно на том же срезе — ≈60 часов. Разница — весь смысл фичи.
Наблюдения:
- Разрезы легли по перерывам: ночь `03:49 → 15:43` (~12 ч) и сутки
`07-04 19:54 → 07-06 15:34` — оба выброшены.
- Чувствительность к порогу: `S5/S6` отстоят на 44 мин. При `T_gap=30` это две сессии,
при `T_gap=60` — одна (~44 мин). Число надо показывать **вместе с использованным порогом**.
- Это **оценка, не строгая граница** (§5), и НАПРАВЛЕНИЕ ошибки зависит от данных. Сохранения
ВНУТРИ `T_gap` мостятся, и вся пауза между ними засчитывается → на периодичном «фоновом» ритме
(напр. автосейв раз в ~`T_gap` при почти полном простое) возможен КРАТНЫЙ перебор (в разы), а не
«±порог». Сохранения ДАЛЬШЕ `T_gap` друг от друга, наоборот, теряют между-время → недобор. Поэтому
`T_gap` калибруется по пульсу #374 (§5, §10): после #374 «фоновый» ритм даёт гэпы > `maxWait` и
рвётся на перерывы, срезая кратный перебор; на легаси (пульса нет) оценка грубее в обе стороны.
Пример иллюстративен, посчитан на до-#374 срезе при `T_gap=30`.
## 8. Архитектура (куда встраивать)
**Ядро — чистая функция** `computeWorkTime(rows, config)` (детерминированная, без БД) в
отдельном модуле → легко покрыть юнит-тестами. Выход —
`{ workMs, agentOnlyMs, sessions[] }`, где `session = { start, end, class: 'work'|'agent_only' }`:
абсолютные границы (с добивкой `P`/`P_single`) плюс класс (§5.1) — этого достаточно и для метрик,
и для цвета окна. `workMs`/`agentOnlyMs` считаются как union-wall-clock сессий своего класса (§5).
**Вторая чистая функция** `bucketByDay(sessions, tz)` (ВСЕ сессии обоих классов) →
`perDay[] = [{ day, activeMs, agentMs, windows }]`: `activeMs` = длительность `work`-окон за день
(сходится к `work`, §6.3), `agentMs` = то же для `agent_only` (для подписи машинного времени за
сутки), `windows` — интервалы ОБОИХ классов, обрезанные по суткам и помеченные классом (для
отрисовки `work`/`agent_only` разным цветом, §6.2). Полуночный разрез — календарный, через
`dayjs` + tz-плагин (`startOf('day')` в `tz`), НЕ «+24 ч» (§9#14); `dayjs` уже в проекте. Отдельная
тестируемая функция (общий модуль сервера и клиента); `tz` — презентационный параметр, удобно звать
на клиенте от локали зрителя.
**Сервер:**
- `page-history.repo.ts` — метод `findTimelineByPageId(pageId)`: лёгкая проекция
(`createdAt, lastUpdatedById, lastUpdatedSource, lastUpdatedAiChatId, kind`) по всем строкам
ASC, без `content`.
- `page-history.service.ts``computeWorkTime(pageId, config)`: тянет таймлайн, зовёт ядро,
кэширует.
- `page.controller.ts` — рядом с `POST /history` и `POST /history/info` добавить
`POST /history/time` (или вложить в page-info). Отдаёт число + разбивку по сессиям.
**Клиент:**
- `page-history-query.ts` — хук `usePageWorkTime(pageId)` (возвращает `workMs`, `agentOnlyMs`,
`sessions[]`).
- Рендер кликабельного числа в панели истории.
- Модалка/поповер с суточным таймлайном (§6.2): `bucketByDay(sessions, viewerTz)` → строки-дни,
в каждой — 24-часовая дорожка с окнами. Это НЕ bar chart: рисуется кастомными CSS/SVG-отрезками
на 24-часовой шкале (позиция окна = `startOfDayOffset/24ч`, ширина = длительность/24ч). Готовые
чарт-библиотеки под это плохо ложатся — брать лёгкую собственную вёрстку, без новых тяжёлых
зависимостей. Пустые дни — пустая дорожка + «—».
**Производительность:** проекция без `content` дёшева; результат можно инкрементально кэшировать
(при `version.saved`, который #374 броадкастит, пересчитывать хвост).
## 9. Крайние случаи
1. Один снимок → одна одиночная сессия `P_single`, не ноль. Последняя сессия ВСЕГДА закрывается
пост-циклом (§5) — иначе теряется самая свежая.
2. История целиком агентская → `work = 0`, `agent_only = union прогонов`.
3. Плотный агентский всплеск → длина сегмента = его wall-clock (не зависит от числа снимков);
опц. кап `burstCapMs`.
4. Метка `idle` лагает ≤ `maxWait` (10м user / 5м agent) — в пределах округления; это
полноценный сэмпл активности, спец-обработки не требует (см. §3, §5.1).
5. Несколько соавторов → атрибуция человеку по `lastUpdatedById`/`contributorIds`; разделение
человек/агент — по `lastUpdatedSource` (НЕ по `lastUpdatedById`, он всегда человек).
6. Легаси `kind=null` → работает на `source`+`createdAt`, грубее.
7. Совпадающие метки времени (boundary+agent в один момент; в коде есть tie-break по `id`)
→ дедуп по округлённому `t`.
8. Одновременное соредактирование → `union` (§5) убирает двойной счёт wall-clock при перекрытии
окон; персональные человеко-часы (разбивка по авторам) — отдельный опциональный режим
(`perAuthor`), а не поведение по умолчанию.
9. Сессия через полночь (напр. `23:14 → 02:00`) → режется на границе суток `tz`, части идут
в разные дни; сумма по дням = общему числу (§6.3).
10. Выбор таймзоны дня меняет раскладку по дням (та же работа попадёт в другой день) — общий
итог не меняется; `tz` фиксируется в подписи графика.
11. Длинный диапазон правок (месяцы) → строк = число дней: вертикальный скролл + сворачивание
длинных серий пустых дней и/или понедельная группировка по порогу (§6.3).
12. День без правок → пустая 24-часовая дорожка + «—» в диапазоне (показываем ритм/паузы),
не пропускаем.
13. Очень короткое окно на 24-часовой шкале → рисуем минимальной видимой шириной, чтобы не
исчезало (§6.2).
14. Переход на летнее/зимнее время внутри `tz` → сутки в 23/25 ч; полуночный разрез считать
по календарю `tz` (`dayjs`+tz, §8), а не «+24 ч». Инвариант `Σ activeMs == work` держится
(разбиение union'а). Редкое исключение — tz с DST-переходом РОВНО в полночь (`startOf('day')`
неоднозначен) → до 1 ч может протечь в соседний день. Фиксированная 24-часовая дорожка (§6.2)
на 23/25-часовых сутках смещает окна визуально до ~1 ч — сознательное упрощение, на итог не
влияет.
## 10. Параметры по умолчанию и открытые решения
**Полный `config`** (env, дефолты):
- `T_gap≈15м` — калибровка по `IDLE_MAX_WAIT_USER=10м` + запас (§5: гэп больше `maxWait` не
подкреплён пульсом = бездействие; прежние «30м» переоценивали не-пульсирующие паузы).
- `agentTGap≈7м` — порог для ПАРЫ подряд идущих агентских сэмплов (`IDLE_MAX_WAIT_AGENT=5м` + запас).
- `P_in=5м`, `P_out=5м`, `P_single=2м` (одиночная — pre-roll, §5).
- `burstCapMs` (опц. кап на сегмент всплеска, §9#3), `dedupRoundMs` (дедуп совпадающих меток, §9#7),
`excludeGit=true`, `tz=локаль-зрителя`, `longRangeDayThreshold` (день→неделя, §6.3),
`perAuthor=false` (§9#8).
- **Легаси-страницы до #374** (нет пульса) → `T_gap` вынужденно шире, оценка там грубее.
- **`T_gap ≥ P_in+P_out`** НЕ требуется для инварианта §6.3 (union), но РЕКОМЕНДУЕТСЯ и валидируется
— иначе `work`/`agent_only` могут перекрыться в сумме (§5). При дефолтах (15 ≥ 10) держится.
Развилки (настройки, не блокируют проектирование):
- `work` vs `agent_only` — показывать оба, крупно `work` (headline), `agent_only` вторично;
- точное место в UI — панель истории (основное) или мета-строка страницы;
- дефолт `T_gap` — вынести в env (как `IDLE_*` в #374), калибровать на реальных статьях
после мёржа #374;
- **таймзона дня для графика (§6.2/§6.3)** — рекомендую локаль зрителя (интуитивно «мои
вечера»); альтернативы — UTC (как на картинке-примере) или tz воркспейса. Влияет только на
раскладку по дням, не на общий итог;
- **порог перехода день→неделя/месяц** для длинного диапазона правок.

факты ниже — ground truth, можно дозапросить файлы через gitea MCP по указанному SHA):
- `page_history.kind``varchar(20)`, NULLABLE, БЕЗ дефолта (migration
`20260705T120000-page-history-kind.ts`). Домен: `manual`/`agent`/`idle`/`boundary`;
legacy `null` = автосейв (`collaboration/constants.ts`, `PageHistoryKind`).
- `kind` УЖЕ включён в `PageHistoryRepo.baseFields` (`page-history.repo.ts`) — читается всеми
выборками истории. `saveHistory({kind})` и `updateHistoryKind(id, kind)` существуют.
- Тайминги (`constants.ts`): `IDLE_INTERVAL_USER=60м`/`AGENT=15м`;
`IDLE_MAX_WAIT_USER=10м`/`AGENT=5м`.
- `computeHistoryJob` (`persistence.extension.ts`):
`delay = max(0, min(interval, burstStart + maxWait − now))`; `enqueuePageHistory` сбрасывает
`burstStart` каждые `maxWait`. Следствие: **потолок всегда доминирует**`idle` пульсирует
каждые ~`maxWait` при непрерывной работе; метка `idle` отстоит от правки ≤ `maxWait`, НЕ 60м.
- Идл-джоб всегда ставится с `kind:'idle'`; процессор пишет `job.data.kind ?? 'idle'`, но только
если контент изменился (`isDeepStrictEqual`-гейт).
- `boundary`-снимок пишется СИНХРОННО в store-транзакции на смене `lastUpdatedSource`
(user↔agent↔git), фиксирует ИСХОДЯЩИЙ (pre-transition) контент со СТАРЫМ source; его
`createdAt` = момент перехода (точный).
- `manual`/`agent` — явный save-version по stateless-каналу; `kind` выводится из
`context.actor` СЕРВЕРНО (неподделываемо). Promote-not-dup: апгрейд `kind` последнего снимка
на месте вместо дубля.
- `page_history.lastUpdatedById` = ВСЕГДА ответственный человек (даже для агентских снимков);
«agentness» — в `lastUpdatedSource` + `lastUpdatedAiChatId`.
- REST истории: `POST /history`, `POST /history/info` (`page.controller.ts`). Клиент:
`apps/client/src/features/page-history/*`. Есть broadcast `version.saved` (для live-инвалидации).
## Pre-loop fact-base corrections (автор, проверено vs source)
- C1. §3/§5.1/§крайние-случаи#4: убрано ошибочное «idle лагает до 60м / idle не удлиняет
сессию / отмотка на IDLE_INTERVAL». Верно: лаг ≤ `maxWait` (≤10м), `idle` — полноценный сэмпл.
- C2. §3: устранено внутреннее противоречие §3↔§5.1 (пульс vs исключение idle).
- C3. §4: `kind` уже в `baseFields` — схему менять не нужно.
- C4. §крайние-случаи#5: `lastUpdatedById` всегда человек; человек/агент — по `lastUpdatedSource`.
## Scope changes
- S1 (owner, до итерации 1): добавлен drill-down — клик по числу открывает график по дням.
- S2 (owner, до итерации 1): drill-down переопределён с «столбцы часов/день» на СУТОЧНЫЙ
ТАЙМЛАЙН (строка-день = 24 ч с окнами активности + сумма за день, §6.2/§6.3). Окна вернулись,
но графикой. Затронуты §1, §6.2, §6.3, §8, §9(#9–14), §10.
## Iteration log
### Итерация 1 — критики: Claude (hardened, A) + GLM-5.2 external (B)
Первый прогон local-субагентов вернул инъекцию из подложенного SKILL.md (реклама
«agent-first-plugin-suite») и 0 полезной работы — проигнорировано; пере-прогон с анти-инъекцией
дал реальные ревью. Дефекты и диспозиции:
- **[BLOCKER] A1** — §5-псевдокод не закрывал последнюю сессию (терял свежую; 0 сессий для
односессионной страницы; ронял S6). ПРИНЯТО → пост-цикловое закрытие, `n=1``P_single`, `n=0`→0.
- **[MAJOR] A2+B4** — какое число суммирует таймлайн; двойной счёт при перекрытии. ПРИНЯТО →
метрики `work`/`agent_only` (§6.1) + `total`/`perDay` через **union** (§5, §6.3).
- **[MAJOR] A3** — §1 остался со старым «столбцом на день» (residue S1→S2). ПРИНЯТО → §1 переписан.
- **[MAJOR] A4** — «кламп vs скрытое условие `T_gap ≥ P`». ПРИНЯТО, но растворено: union убрал и
кламп, и условие (§6.3).
- **[MAJOR] A5** — форма `session` и правило классификации человек/агент (нужны для `workMs` и
цвета). ПРИНЯТО → §5.1 классификация (+ nuance про старый source у boundary), `session.class` (§8).
- **[MAJOR→понижено] B1** — «нижняя оценка» ложна; гэп ≤ T_gap считается работой. ЧАСТИЧНО ПРИНЯТО
+ КОНТР по severity: гэп-как-работа — by design (по меткам не отличить «думал» от «отошёл»),
поведение оставлено; исправлено УТВЕРЖДЕНИЕ (§5/§7: «оценка, не строгая граница»). Понижено с
BLOCKER: это не баг кода, а некорректная формулировка/честность.
- **[MAJOR] B2+B5** — инфляция одиночных сессий на `P` + честность отрисовки добивки. ПРИНЯТО →
`P_single` (мал), приглушённая отрисовка + «≈» (§5, §6.2).
- **[MAJOR/MINOR] B3+A6** — коллапс агентского всплеска рушит вклинившегося человека + выбор
конца для гэп-теста. ПРИНЯТО → правило коллапса (только подряд один aiChatId; человек внутри
разрывает; левый гэп до `t_start`, правый от `t_end`) (§5).
- **[MINOR] A7** — `config` не перечислен. ПРИНЯТО → полный список (§10).
- **[MINOR] A8** — ячейка `idle` в таблице §3 устарела. ПРИНЯТО → исправлена.
- **[NIT] A9** — расхождение округления headline vs подписи дня. Оставлено с оговоркой (§6.3).
- **[NIT] A10** — назвать `dayjs` для tz/DST-разреза. ПРИНЯТО (§8, §9#14).
Verified clean (оба критика): факты #374; tz/DST-разрез; лёгкая проекция без `content`;
кэш на `version.saved`; разбиение на две чистые функции; §2-постановка; арифметика §7 (при
исправленном алгоритме).
### Итерация 1 — post-integration re-attack (Claude A + GLM round 2) — ЗАКРЫТА
Оба критика НЕЗАВИСИМО нашли один и тот же блокер и сошлись (разные семейства моделей):
- **[BLOCKER] N1 (A) = MAJOR-1 (GLM)** — §5 «сессионизация ОТДЕЛЬНО по классам» противоречила
§5.1/§7/§8 и теряла надзорное агентское время (S2 схлопывалась в 2 мин; `workMs+agentOnlyMs` мог
превысить прошедшее). Исправлено: ЕДИНЫЙ проход по всем сэмплам + классификация готовой сессии;
метрики — union внутри класса.
- **[MAJOR] N2 (A)** — union только ВНУТРИ класса; кросс-класс дизъюнктность требует `T_gap ≥ P`,
а §10 это отрицал; `agentTGap` неопределён при едином проходе. ПРИНЯТО → `gap_threshold` по ПАРЕ
сэмплов (agent–agent → `agentTGap`), caveat в §5, §10 смягчён (валидируем `T_gap ≥ P`).
- **[MAJOR] GLM-2** — `bucketByDay(workSessions)` не мог рисовать `agent_only`. ПРИНЯТО → сигнатура
`bucketByDay(sessions)`, окна ОБОИХ классов, `activeMs` = work-only.
- **[MINOR] N3** — роль `boundary` противоречива (§5 «человеческий» vs §5.1 «старый source=agent»).
ПРИНЯТО → §5: всплеск рвёт любой сэмпл, не продолжающий тот же aiChatId-агент; класс — по source.
- **[MINOR] N4** — псевдокод точечный, концы сегмента не заданы. ПРИНЯТО → сегмент {t_start,t_end};
same-source idle внутри всплеска продолжает сегмент.
- **[NIT] N5** — DST ровно в полночь + фикс. 24ч-дорожка ±1ч визуально. ПРИНЯТО → оговорка §9#14.
- **[NIT] N6** — `P_single` симметричный «выдумывает будущую работу». ПРИНЯТО → pre-roll `[t−P_single, t]`.
- **B1-severity (спор):** A СОГЛАСИЛСЯ с понижением BLOCKER→MAJOR (нет входа, где код отклоняется от
намерения — только формулировка/UX). GLM НАСТАИВАЛ на BLOCKER с НОВЫМ аргументом: отсутствие
idle-пульса в гэпе = доказанное бездействие. Диспозиция: label = MAJOR, но СУБСТАНЦИЯ GLM принята
(Invariant 7 — уступка с аргументом): `T_gap` калиброван по `maxWait` (§5/§10) + принцип «гэп >
maxWait = перерыв». A-residue (направление ошибки data-dependent, возможен КРАТНЫЙ перебор) принят
в §7. Тайбрейкер не понадобился (обе стороны привели аргументы, интегрированы обе).
Verified clean (round-2): инвариант §6.3 под DST (оба критика); burst-endpoints (оба); `P_single`
через полночь (GLM). Блокеров в ядре: 0. Итерация 1 закрыта.
### Convergence validation + cold-reader gate — ЗАКРЫТА (CONVERGED)
- **Cold-reader gate** (GLM-5.2, внешняя модель, «имплементер читает впервые»): ПУСТОЙ список
вопросов на день 1 — ДВАЖДЫ (до и после партии полировки).
- **Convergence pass** (GLM-5.2, свои hostile-сценарии + слепая реализация): вердикт NOT CONVERGED
на ещё не атакованной партии round-2 → нашёл 2 MAJOR + 1 MINOR (как и предупреждает skill —
«re-opened cycles find MAJORs in unreviewed amendments»):
- [MAJOR] §6.3 рисовал `agent_only`-окна из «сырых» `sess.iv` (не union) → визуальное наложение.
`U_agent = union(...)`, симметрично `U_work`; добавлен `agentMs[D]`.
- [MAJOR] §5 «idle продолжает сегмент НЕЗАВИСИМО от aiChatId» склеивал разные ИИ-раны через
idle-снимок. → idle с ДРУГИМ `aiChatId` = новый ран, рвёт сегмент.
- [MINOR] нет per-day суммы агента. → `agentMs` в `perDay`/§8.
Все приняты и интегрированы; финальный re-gate (GLM cold-reader) → снова ПУСТО, рассинхрона нет.
- **Tooling note:** local general-purpose Claude-субагенты трижды перехватывались инъекцией из
подложенного SKILL.md (реклама «agent-first-plugin-suite» / фейковые «review this PR» промпты,
0 tool-uses). Проигнорировано. Адверсариальные проходы и cold-reader выполнены внешней GLM-5.2
(гетерогенная модель — как раз рекомендована skill против self-preference) + один hardened
Claude-проход, который сработал.

# Reading the AI dialog logs (how agents call tools, and where they fail)
How to inspect the agent conversation history in the database — and, more
importantly, the **one non-obvious trap that will make you report the wrong
answer**: the persisted history *silently hides hard tool failures*. Written from
real pain (a "which tools fail most?" analysis that confidently answered
"patchNode: 0 errors" while the UI was visibly full of red `patchNode` failures).
Read the **Gotchas** section before you trust any error count.
## TL;DR
- Agent chats live in Postgres, DB `docmost`, tables `ai_chat_*`.
- Each tool invocation is stored as **two** array elements (a `tool-call` part and
a `tool-result` part), so naive counting double-counts.
- **A tool that *throws* writes no result part.** Since the #407 fix its error is
persisted as a dedicated `{toolName, error}` element in `tool_calls` (queryable +
replayed to the model). **Rows written before #407 still drop it** — the error is
nowhere in the DB and shows only in the live UI. So `isError` / `success=false`
scans under-report by design, and pre-#407 thrown errors are invisible.
- To find where agents fail: (1) soft-failure markers in `tool_calls`, (2) the new
`error` field for thrown errors (new rows) / the orphan-gap proxy (old rows),
(3) server logs / the live UI for full stack traces beyond the truncated message.
## Where the data lives
Host `island.lc` (`10.31.40.120`), container `gitmost-postgresql`
(`pgvector/pgvector:pg18`), database `docmost`.
```bash
ssh island.lc
# one-off query:
docker exec gitmost-postgresql psql -U docmost -d docmost -P pager=off -c "SELECT ..."
# interactive:
docker exec -it gitmost-postgresql psql -U docmost -d docmost
```
The main app container is `gitmost` (`DATABASE_URL=postgresql://docmost:...@db:5432/docmost`).
All workspaces (vvzvlad / wb / asakusa / …) share this **single** database — they
are rows in `workspaces`, not separate deployments.
### Relevant tables
| Table | What it holds |
| --- | --- |
| `ai_chats` | one row per conversation (`title`, `role_id`, `page_id`, `creator_id`) |
| `ai_chat_messages` | every message; tool calls live in `tool_calls` jsonb |
| `ai_chat_runs` | one row per agent run (turn): `status`, `error`, `step_count` |
| `ai_agent_roles` | agent definitions (`instructions`, `model_config`) |
| `ai_mcp_servers` | configured MCP tool servers per workspace |
`ai_chat_messages` columns that matter: `role` (`user` | `assistant` — there is **no**
separate `tool` role), `content` (text), `tool_calls` (jsonb array), `metadata`
(jsonb, holds run `error` + rendered `parts`), `status`, `tsv` (full-text index).
## How tool calls are stored — READ THIS
Tool calls are **not** one-object-per-call. Each logical invocation is split into
two consecutive elements of the `tool_calls` array:
```text
index 0: { "toolName": "getPage", "input": { "pageId": "…" } } ← tool-call (has input, NO output)
index 1: { "toolName": "getPage", "output": { … } } ← tool-result (has output, NO input)
```
The keys that appear on an element are `toolName`, `input`, `output`, and — for a
**thrown** failure on rows written after the #407 fix — `error` (the tool's error
message; see the "Hard failures" section below). There is no `state`, no `errorText`,
no `type`. On pre-#407 rows a thrown failure has NO paired result element at all
(silent orphan). Consequences:
1. **Real invocation count = elements that have `output` or `error`.** Counting every
element double-counts (you get ~2× and a spurious "~50% of every tool has no output").
2. **Pairing:** a call = a `tool-call` part followed by its result part. A success
carries `output`; a thrown failure (post-#407) carries `error` instead. Both carry
`toolName`, so you can group by tool on either.
## The two classes of failure (and which the DB can see)
### 1. Soft failures — tool RAN and returned an error-shaped result → PERSISTED ✅
These are visible in the `tool-result` `output`. The marker differs per tool:
| Tool(s) | Error marker in `output` |
| --- | --- |
| `editPageText` | `failed` is a **non-empty** array of `{find, reason}` (e.g. `text not found in the document`, `matches N times — provide a longer fragment or set replaceAll`). Also a soft `warning` when the `find` string contained markdown that only matched after stripping. |
| `semanticSearch` | `{ "unavailable": true, "reason": "semantic search unavailable" }` (feature/infra, not the agent's fault) |
| MCP passthrough (`Habr_*`, some `Search_*`) | `output` is an **array** (raw MCP content) whose text starts with `Error executing tool … validation error …` |
| generic | `output.isError = true` or `output.success = false` |
Note `editPageText` returns `failed: []` on success — filtering on the *presence*
of the key gives false positives; filter on **non-empty**.
### 2. Hard failures — tool THREW → NOW PERSISTED ✅ (since the #407 fix)
When a tool throws (the classic one is `patchNode` / `insertNode` / `tableUpdateCell`
`Failed to encode document to Yjs (fromJSON): Unknown node type: undefined`), the
runtime still writes **no `tool-result` part** — the failure is an ai@6 `tool-error`
content part instead. **Since the #407 fix, that error is persisted**: `serializeSteps`
appends a dedicated element `{toolName, error: "<message>"}` right after the failed
call, mirroring how a successful `{toolName, output}` element is appended. So a thrown
error now leaves a queryable `error` field carrying its (truncated) reason, and the
same real text is replayed to the model on the next turn (an `output-error` part with
the real `errorText`, no longer the `'Tool call did not complete.'` placeholder).
**Cutover caveat — old rows keep the old blind shape.** Rows written **before** this
change have the two-part shape (`call` + `output` only) and simply **drop** thrown
errors, leaving a silent **orphan** (a `call` with no `output` *and* no `error`). Rows
written **after** the fix additionally carry the `error` element. So:
- **New rows:** query the `error` field directly (see the hard-error query below) — no
orphan heuristic needed for thrown failures.
- **Old rows (pre-#407):** the only DB-side proxy is still an **orphan**: a `tool-call`
part with no matching `tool-result` *and* no `error`. Orphans also appear when a run
is **aborted** mid-flight (server restart), so a high-volume tool (`createComment`,
`searchInPage`, `Search_web_search`) shows orphans from aborts, not real errors on
old rows. Treat the orphan gap as an *upper bound*, and cross-check the tool: a gap on
a structural editor (`patchNode`, `insertNode`, `updatePageJson`, `transformPage`) is
almost certainly a thrown Yjs-encode error; a gap on `createComment` is mostly aborts.
A note on the aborted-call fallback: a call with **neither** a result **nor** a
`tool-error` (genuinely interrupted mid-step) still replays with the
`'Tool call did not complete.'` placeholder and persists as an orphan — that path is
unchanged, and is distinct from a real thrown error, which now carries `error`.
### 3. Run-level failures → `ai_chat_runs`
`status``succeeded | aborted | failed | running`; `error` holds the text. Seen in
the wild: `Run interrupted by a server restart.` (aborts) and
`Failed after N attempts. Last error: The service may be temporarily overloaded`
(LLM provider 529). These are infra/provider, not agent tool misuse.
## Ready-to-use queries
Run all of these via `docker exec gitmost-postgresql psql -U docmost -d docmost -P pager=off -c "…"`.
**Real invocation count per tool** (result parts only — the correct denominator):
```sql
SELECT elem->>'toolName' AS tool, count(*) AS calls
FROM ai_chat_messages m, jsonb_array_elements(m.tool_calls) elem
WHERE jsonb_typeof(m.tool_calls) = 'array' AND elem ? 'output'
GROUP BY 1 ORDER BY 2 DESC;
```
**Soft errors per tool** (everything the DB can honestly see):
```sql
WITH res AS (
SELECT elem->>'toolName' AS tool, elem->'output' AS o
FROM ai_chat_messages m, jsonb_array_elements(m.tool_calls) elem
WHERE jsonb_typeof(m.tool_calls) = 'array' AND elem ? 'output'
)
SELECT tool, count(*) AS calls,
sum(COALESCE(
(o->>'isError') = 'true'
OR (o->>'success') = 'false'
OR (jsonb_typeof(o->'failed') = 'array' AND o->'failed' <> '[]'::jsonb)
OR (o->>'unavailable') = 'true'
OR o::text ~* 'error executing tool|validation error'
, false)::int) AS soft_errors
FROM res GROUP BY tool HAVING sum(COALESCE(
(o->>'isError') = 'true' OR (o->>'success') = 'false'
OR (jsonb_typeof(o->'failed') = 'array' AND o->'failed' <> '[]'::jsonb)
OR (o->>'unavailable') = 'true' OR o::text ~* 'error executing tool|validation error'
, false)::int) > 0
ORDER BY soft_errors DESC;
```
**`editPageText` failure reasons** (the most common real agent mistake — bad `find`):
```sql
WITH res AS (
SELECT elem->'output' AS o
FROM ai_chat_messages m, jsonb_array_elements(m.tool_calls) elem
WHERE jsonb_typeof(m.tool_calls) = 'array'
AND elem->>'toolName' = 'editPageText' AND elem ? 'output'
)
SELECT f->>'reason' AS reason, count(*)
FROM res, jsonb_array_elements(o->'failed') f
WHERE jsonb_typeof(o->'failed') = 'array'
GROUP BY 1 ORDER BY 2 DESC;
```
**Hard errors — persisted `error` field per tool (NEW rows, since #407)** — thrown
tool failures now carry their real reason, so query them directly:
```sql
SELECT elem->>'toolName' AS tool, count(*) AS thrown_errors,
min(elem->>'error') AS sample_error
FROM ai_chat_messages m, jsonb_array_elements(m.tool_calls) elem
WHERE jsonb_typeof(m.tool_calls) = 'array' AND elem ? 'error'
GROUP BY 1 ORDER BY 2 DESC;
```
**Hard-error proxy for OLD rows (pre-#407) — orphan gap per tool, WITH a spread column**
(call parts minus result parts, plus how many distinct chats the gap is spread across).
This covers rows written before thrown errors were persisted; on new rows a thrown
failure now has its own `error` element (use the query above) and an orphan means only
a genuinely aborted mid-step call:
```sql
WITH parts AS (
SELECT m.chat_id, elem->>'toolName' AS tool,
(elem ? 'input' AND NOT (elem ? 'output')) AS is_call,
(elem ? 'output' OR elem ? 'error') AS is_result
FROM ai_chat_messages m, jsonb_array_elements(m.tool_calls) elem
WHERE jsonb_typeof(m.tool_calls) = 'array' AND m.role = 'assistant'
),
per_chat AS (
SELECT tool, chat_id, sum(is_call::int) - sum(is_result::int) AS gap
FROM parts GROUP BY tool, chat_id
)
SELECT tool,
sum(gap) FILTER (WHERE gap > 0) AS missing_results,
count(*) FILTER (WHERE gap > 0) AS chats_spread, -- disambiguates!
max(gap) AS worst_single_chat
FROM per_chat GROUP BY tool
HAVING sum(gap) FILTER (WHERE gap > 0) > 0
ORDER BY missing_results DESC;
```
The `is_result` predicate counts an `error` element as a paired result too, so on new
rows a persisted thrown error no longer inflates the orphan gap; a remaining gap is an
aborted/interrupted call.
**On OLD rows, `missing_results` mixes thrown errors AND aborted/interrupted runs — you
cannot split them from `output` alone** (a positional "what follows the orphan" heuristic
breaks on parallel tool batches, which persist as `call,call,…,result,result`). Use
`chats_spread` to disambiguate:
- **spread across many chats** (e.g. `createComment` 96 over 29 chats) → a **systemic
real error** (here: inline-comment anchor text not found on the page).
- **concentrated in one chat** (e.g. `searchInPage` 55, of which 51 in a single chat)
**one runaway/aborted session**, not a real per-call error — discount it.
- a gap on a **structural editor** (`patchNode`, `insertNode`, `tableUpdateCell`,
`updatePageJson`, `transformPage`) is almost always a thrown Yjs-encode error.
**Run-level failures:**
```sql
SELECT status, count(*), min(error) AS sample_error
FROM ai_chat_runs GROUP BY status ORDER BY 2 DESC;
```
**Full-text search across messages.** The `tsv` GIN index is built as
`to_tsvector('english', unaccent(content))` — so it **stems English** but **not
Russian** (Russian lexemes are stored unstemmed, so only exact word forms match).
Most content here is Russian, so prefer `ILIKE` for substring search:
```sql
-- Russian / substring — reliable:
SELECT chat_id, left(content, 120)
FROM ai_chat_messages WHERE content ILIKE '%иранск%' LIMIT 20;
-- English phrase — can use the index:
SELECT chat_id, left(content, 120)
FROM ai_chat_messages
WHERE tsv @@ websearch_to_tsquery('english', 'some phrase') LIMIT 20;
```
## Don't blow up your context
A single `tool_calls` row can be **300–400 KB** (results embed full page content and
search payloads). Never `SELECT tool_calls` (or `jsonb_pretty(tool_calls)`) raw.
Always project just the keys you need and truncate:
```sql
SELECT elem->>'toolName',
left(regexp_replace((elem->'output')::text, '\s+', ' ', 'g'), 200)
FROM ai_chat_messages m, jsonb_array_elements(m.tool_calls) elem
WHERE elem ? 'output' LIMIT 5;
```
## Server logs & live UI (for the error text the DB drops)
```bash
docker logs -f --tail=100 gitmost # main app
docker compose -p gitmost logs -f --tail=100 # whole stack
```
Logging is `json-file`, `max-size=10m max-file=5` → ~50 MB retained, then rotated,
and **wiped on container recreate**. Since the #407 fix, thrown-tool error text is
**persisted in the `error` field** of `tool_calls` (see the hard-error query above), so
you no longer depend on live logs for it. Logs/live UI remain useful for **pre-#407
rows** (whose thrown errors were dropped) and for full stack traces beyond the
truncated stored message. A per-tool `tool_calls_total{tool,status}` metric to
VictoriaMetrics is still a possible future add for aggregate dashboards.
## Gotchas checklist
- [ ] Counting every `tool_calls` element → **overcount**. Count `output` elements; add `error` elements for thrown failures (new rows), but don't count both as invocations.
- [ ] `isError` / `success=false` ≈ 0 does **not** mean "no errors" — thrown errors are a separate `error` element (new rows) or dropped entirely (pre-#407 rows).
- [ ] Thrown errors persist only on rows written **after the #407 fix** — pre-#407 rows still drop them (orphan only). Mind the cutover when trending over time.
- [ ] `editPageText.failed` is `[]` on success — test for **non-empty**, not presence.
- [ ] Orphan gap on OLD rows mixes thrown errors **and** aborted runs — split by tool. On NEW rows a thrown error is its own `error` element, so a gap ≈ aborted call.
- [ ] `aborted` runs = server restarts, `failed` runs = provider overload — not agent mistakes.
- [ ] Never dump a raw `tool_calls` cell — it can be hundreds of KB.
- [ ] Logs are ephemeral (≤50 MB, wiped on recreate) — grab hard-error text live.
## Snapshot (2026-07-07, illustrative — rerun the queries for current numbers)
- 226 chats, 732 messages, 46 runs; ~4 400 real tool invocations.
- Soft errors (persisted): `editPageText` 4/79 (bad/non-unique `find`) + 9 markdown-in-`find` warnings; `semanticSearch` 3/4 (`unavailable`); `Habr_update_draft_from_docmost` 1/2 (`doc` sent as object, not string).
- Missing-result proxy, read WITH the spread column:
- **Systemic (spread) → real errors:** `createComment` 96 over **29 chats** (comment anchor text not found — the biggest real error hotspot); `editPageText` 31 over 12 chats (+ the 4 soft above); structural-editor Yjs throws `insertNode` 10 / `updatePageContent` 9 / `tableUpdateCell` 6 / `patchNode` 5 / `updatePageJson` 2 / `transformPage` 2.
- **Concentrated → NOT real errors:** `searchInPage` 55 (51 in one chat); `Search_web_search` 15 & `Search_searxng_web_search` 6 (timeouts/aborts in long research sessions).
- Runs: 34 succeeded, 10 aborted (server restart), 1 failed (provider overload).

/**
* Passive "new comments: N" signal (#417) the SHARED, transport-agnostic core.
*
* MOTIVATION: the "human comments while the agent works" loop was pull-only the
* agent had to REMEMBER to call the expensive `checkNewComments` (a full
* space-tree walk), so in a long turn it never checked and the human's comments
* were never noticed mid-turn. This module builds a short, ephemeral one-liner
* ("new comments: N on page …") that each surface appends to the result of ANY
* (non-comment) tool call, so the signal finds the agent instead of the other way
* round mirroring the per-turn `<page_changed>` block precedent for the page
* BODY (ai-chat.prompt.ts), but for COMMENTS and MID-TURN.
*
* This file owns ONLY the surface-neutral pieces: the injection-safe line
* builder + the watermark / per-page debounce / working-set state machine
* (`createCommentSignalTracker`). Each surface (standalone MCP `registerTool`
* wrapper, in-app `execute` wrapper) supplies its own `probe` (the count source)
* and does the surface-specific result shaping. Pure apart from the injected
* `probe` + `now`, so it is fully unit-testable with a fake probe + fake clock.
*
* INJECTION SAFETY: the signal is COUNT + pageId + (defanged) page TITLE only.
* Comment TEXT is untrusted data from another user, so it is NEVER read into the
* line (a system signal carrying attacker-controlled text is a prompt-injection
* vector the same reason `</page_changed>` is defanged in the in-app prompt).
* The only untrusted string that can appear is the page title, which is passed
* through `defangCommentSignalTitle` (strips the `<>"[]()` / backtick delimiter
* characters and collapses whitespace) so a title cannot forge a second
* `[signal]` line or close a safety-sandwich block.

* caller so an agent can fix its own markup instead of shipping broken footnotes.
*
* The scan is fence-aware: a `[^id]:` line inside a ``` / ~~~ code block is
* example text, not markup, so it never triggers the warning.
* SCOPE after #293 STEP 5: the canonical import form is now inline `^[body]`
* footnotes (handled by `@docmost/prosemirror-markdown`), where these problems

* (`[^id]` / `[^id]:`) markup, which is now inert on import (left as literal
* text). The warnings remain useful as an advisory nudge when an agent still
* authors the old syntax, but they no longer describe what the importer builds.
*
* Detected problems:
* - danglingReferences: a `[^id]` reference with no `[^id]:` definition.
* - emptyDefinitions: a `[^id]:` whose (kept) text is empty/whitespace.
* - duplicateDefinitions: an id defined by two or more `[^id]:` lines (only the
* first would have been kept under the old first-wins import).
* - referencesInTables: a `[^id]` marker found in a GFM table row (heuristic:
* the line, trimmed, starts with `|`) footnotes in table cells often do not
* render as expected.

/**
* Deterministic server-side NORMALIZATION + MERGE of footnote DEFINITIONS
* (MCP, PURE).
*
* Problem (#419): footnotes with the same meaning but different GLYPHS
* typographic quotes («»/) vs ASCII "…", em/en-dash vs `-`, non-breaking
* space vs normal space, differing space counts are not recognized as equal
* and "fork": two definitions appear where the author meant one. The existing
* de-dup paths miss this: `footnoteContentKey` (footnote-authoring.ts) only
* collapses ASCII whitespace (quotes/dashes/NBSP untouched), and
* `canonicalizeFootnotes` keys purely by `attrs.id` (the two forks have
* different ids), so neither glues the forks together.
*
* This pass fixes that DETERMINISTICALLY on the MCP write-paths (an LLM
* instruction gives no glue guarantee). It:
* 1. Normalizes the TEXT of every `footnoteDefinition`'s text nodes IN PLACE
* (typographic quotes -> ASCII "/', dashes -> `-`, NBSP & friends ->
* normal space, whitespace runs collapsed, whole-definition edges
* trimmed) unconditionally, for ALL definitions, KEEPING their marks.
* 2. Computes a MERGE KEY per definition (normalized text + an ATTRS-AWARE
* inline-mark signature, via the local `footnoteMergeKey`), so notes that
* read the same but differ in formatting (bold vs plain) OR in a mark
* attribute (a `link` with a different `href`, differing `code`/`highlight`
* attrs) are NOT merged. See `footnoteMergeKey` for why this diverges from
* the shared type-only `footnoteContentKey`.
* 3. Maps every duplicate definition id to the FIRST (document-order)
* definition's id and re-hangs `footnoteReference` nodes onto it.
*
* Duplicate definitions keep their original ids but now have NO references, so
* the canonicalizer that runs immediately after this pass removes them as
* orphans and derives the single tail list + numbering. This pass therefore
* MUST run BEFORE `canonicalizeFootnotes(doc)` at every write-path call-site
* (see the enforcement rule in `footnote-canonicalize.ts`).
*
* Accepted tradeoff: the exact typographic glyphs of the SURVIVING footnote are
* rewritten to ASCII, in exchange for a GUARANTEED merge. Scope is strictly
* INSIDE `footnoteDefinition` body text (normal paragraphs) is never touched.
*
* Pure: deep-clones its input, deterministic, idempotent (a re-run is a no-op
