* 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.

|

* 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.

a `tool-result` part), so naive counting double-counts.

- **A tool that *throws* writes no result part.** Since the #407 fix its 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.

### 2. Hard failures — tool THREW → NOW PERSISTED ✅ (since the #407 fix)
|
||||
### 2. Hard failures — tool THREW → NOT PERSISTED ❌ (the trap)
|
||||
|
||||
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).
|
||||
runtime writes **no `tool-result` part**. The orphaned `tool-call` part stays, but
|
||||
the error text is **nowhere in the DB**. It is streamed to the UI live and (until
|
||||
rotation) to server logs — that is it.
|
||||
|
||||
**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:
|
||||
So any query like `count(*) FILTER (WHERE output.success = false)` will happily
|
||||
return **0** for `patchNode` even when the chat is visibly full of red failures.
|
||||
That is survivorship bias, not reliability.
|
||||
|
||||
- **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`.
|
||||
The only DB-side proxy for a thrown error is an **orphan**: a `tool-call` part with
|
||||
no matching `tool-result`. Caveat: 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 from real errors. Treat the

## 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.
|
||||
- [ ] Counting every `tool_calls` element → **2× overcount**. Count elements with `output`.
|
||||
- [ ] `isError` / `success=false` ≈ 0 does **not** mean "no errors" — thrown errors aren't persisted.
|
||||
- [ ] `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.
|
||||
- [ ] Orphan gap mixes thrown errors **and** aborted runs — split by tool before concluding.
|
||||
- [ ] `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.

|
||||
* 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.
