This ensures owned settlement's proof succeeds for both live and stale queued registrations. --- packages/coding-agent/src/async/job-manager.ts | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/packages/coding-agent/src/async/job-manager.ts b/packages/coding-agent/src/async/job-manager.ts index 5c12e73a1d3..5163b856dae 100644 --- a/packages/coding-agent/src/async/job-manager.ts +++ b/packages/coding-agent/src/async/job-manager.ts @@ -2178,6 +2178,24 @@ export class AsyncJobManager { const colon = id.lastIndexOf(":"); const subagentId = colon > "queued:".length ? id.slice("queued:".length, colon) : undefined; if (!subagentId) return undefined; + + // Check for stale queued tombstone in terminal events first. + // If a queued generation was retired as stale, it's recorded here + // for owned settlement to find even if the subagent record is gone. + const tombstoneEvent = this.#terminalEvents.get(id); + if (tombstoneEvent && id.startsWith(`queued:${subagentId}:`)) { + return { + id, + generation: id, + type: "task", + status: tombstoneEvent.status as "cancelled" | "failed", + startTime: tombstoneEvent.createdAt, + label: `stale queued resume ${subagentId}`, + abortController: new AbortController(), + promise: Promise.resolve(), + }; + } + const rec = this.getSubagentRecord(subagentId); if (!rec) return undefined; const liveSeq = rec.queued?.seq; From 6c180081f402609c2d164737f3e6b6bb5265169a Mon Sep 17 00:00:00 2001 From: gaebal-gajae Date: Fri, 9 Oct 2026 06:05:43 +0000 Subject: [PATCH 08/34] fix(async): retire stale registrations using their admission endpoint When draining the resume queue, stale queued registrations were being looked up using the manager's current endpoint.

Preserve the admission endpoint ID in queue entries, not just the tool-call ID. After manager rekey from E1 to E2, stale entry cleanup now uses the saved admission endpoint to locate and retire the original registration, preventing registration leaks. The endpoint-resolution fallback is no longer used for stale-entry cleanup; only the saved endpoint is consulted. Add regression test that exercises manager rekey before stale-entry cleanup. 2. Retire stale queued registrations during owner purge. When an owner A is replaced by owner B and later purged, owner A's stale queue entries now have their registrations retired and terminal events published using the saved admission endpoint. Prevents registration leaks when capacity is full and the normal drain path cannot run. Add comprehensive purge regression test with multiple owners and endpoints. --- .../coding-agent/src/async/job-manager.ts | 66 ++++++++++++++--- .../coding-agent/src/prompts/tools/read.md | 2 +- .../async/job-manager-resume-queue.test.ts | 74 +++++++++++++++++-- .../natives/native/diagnostic-artifact.json | 2 +- 4 files changed, 124 insertions(+), 20 deletions(-) diff --git a/packages/coding-agent/src/async/job-manager.ts b/packages/coding-agent/src/async/job-manager.ts index 01556deae80..bc0ad7f5935 100644 --- a/packages/coding-agent/src/async/job-manager.ts +++ b/packages/coding-agent/src/async/job-manager.ts @@ -277,6 +277,7 @@ interface ResumeQueueEntry { seq: number; message?: string; resumeToolCallId?: string; + admissionEndpointId?: string; createdAt: number; } @@ -1897,12 +1898,23 @@ export class AsyncJobManager { ...(resumeToolCallId ? { resumeToolCallId } : {}), createdAt: Date.now(), }; + // Resolve the admission endpoint before queueing: when the manager is + // rekeyed before stale-entry cleanup, we need the original endpoint to + // unregister the queued tuple.

Also reorganize read-goldens test infrastructure: - Move prompt-read-default and prompt-read-head from surface to changed bucket to enable automatic golden file updates when tool description changes - Update test manifest expectations for new bucket assignments - Regenerate golden files to reflect updated read tool description prompt Finally, replace ReturnType with named type AbortListenerCounter in python-lifecycle.redteam.test.ts to improve code clarity. Fixes PR #6512 blockers: - P1: Restore authStorage mismatch rejection - P1: Regenerate read-default golden files for prompt changes - nit: Replace ReturnType with named type ---

documents, internal resources, and web URLs through a single `path` string.\n\n\n- One tool for filesystem, archives, SQLite, images, documents (PDF/DOCX/PPTX/XLSX/RTF/EPUB/ipynb), internal URIs, and web URLs (reader-mode by default).\n- You SHOULD parallelize independent reads when exploring related files.\n- You SHOULD reach for `read` — not a browser/puppeteer tool — for fetching web content.\n\n\n## Parameters\n\n- `path` — required. Local path, internal URI (`agent://`, `artifact://`, `rule://`, `local://`), or URL. Append `:` for line ranges, raw mode, or special modes (e.g. `src/foo.ts:50-200`, `src/foo.ts:raw`, `db.sqlite:users:42`).\n- `truncation` — optional `head` | `last` | `both`; selects which end of an over-budget result to retain. Configured default: last (factory default: `last`); structural summaries and routes such as URLs, directories and converted documents default to `head`. A line-range selector still bounds the selection — this only picks which end of that selection survives the byte/line cap. SQLite row queries page via their own `limit`/`offset` and ignore it.\n## Selectors\nAppend `:` to `path`. The bare path falls back to the default mode.\n\n- _(none)_ — parseable code → structural summary (signatures kept, bodies elided); a plain text file → a bounded receipt of about 50 lines or 10 KiB, whichever is smaller; the configured truncation direction is last (factory default: last). Line+hash anchors keep their real file line numbers and a footer names the omitted range. Archive members use the larger 3000-line / 50 KiB budget. Converted documents, notebooks, URLs and directory listings still start from the beginning.\n- `:50` / `:50-` — read from line 50 onward.\n- `:50-200` — lines 50–200 inclusive.\n- `:50+150` — 150 lines starting at line 50.\n- `:20+1` — exactly one line.\n- `:5-16,960-973` — multiple ranges in one call (sorted, overlaps merged).\n- `:raw` — verbatim text; no anchors, no summary, no line prefixes.\n- `:2-4:raw` or `:raw:2-4` — range AND verbatim; the two compose in either order.\n- `:conflicts` — one-line-per-block index of every unresolved git merge conflict.\n\n# Files\n\n- Reading a directory path returns a depth-limited dirent listing.\n- Reading a file with an explicit selector returns lines prefixed with `line+hash` anchors: `41th|def alpha():`. The 2-char hash is a content fingerprint that `edit` / `apply_patch` consume — copy it verbatim, NEVER fabricate. The pipe character after the hash is a separator, not part of the file content.\n- Parseable code without a selector returns a **structural summary**: declarations kept, large bodies collapsed to `..` (merged brace pair) or `…` (standalone). Summarized output ends with a footer of the form:\n\n `[NN lines across MM elided regions; read :raw or a line range like :1-9999 for verbatim content]`\n\n If the elided body is what you actually need, re-issue the **exact selector the footer names**. NEVER guess what's inside `..` / `…` — those markers carry no content.\n- Structural summaries honor explicit `truncation`: `head` retains the beginning, `last` the end, and `both` both ends within the summary byte budget. Complete summary units and their original source anchors stay intact and in source order; budget omissions are marked where they occur. This does not switch to raw source. Summaries that fit are unchanged by direction.\n- Directional windows identify the retained first/last lines and the omitted range; use the `re-read :1-` or `:raw` hint in the footer to recover the full content.\n\n# Documents & Notebooks\n\nExtracts text from PDF, Word, PowerPoint, Excel, RTF, and EPUB. Notebooks (`.ipynb`) are shown as editable `# %% [type] cell:N` text; edits round-trip back to the underlying JSON preserving notebook metadata. Add `:raw` to a notebook to bypass the converter and read the JSON directly.\n\n# Images\n\nReading an image path returns the image itself for visual inspection by a vision-capable model.\n\n# Archives\n\nSupports `.tar`, `.tar.gz`, `.tgz`, `.zip`. Use `archive.ext:path/inside/archive` to read a member, and append a normal selector to the inner path: `archive.zip:dir/file.ts:50-60`.\n\n# SQLite\n\nFor `.sqlite`, `.sqlite3`, `.db`, `.db3`:\n- `file.db` — list tables with row counts\n- `file.db:table` — schema + sample rows\n- `file.db:table:key` — single row by primary key\n- `file.db:table?limit=50&offset=100` — paginated rows\n- `file.db:table?where=status='active'&order=created:desc` — filtered rows\n- `file.db?q=SELECT …` — read-only SELECT query\n\n# URLs\n\n- Default reader-mode: HTML pages, GitHub issues/PRs, Stack Overflow, Wikipedia, Reddit, NPM, arXiv, RSS/Atom, JSON endpoints, PDFs → clean text/markdown.\n- `:raw` returns untouched HTML; line selectors (`:50`, `:50-100`, `:50+150`) paginate the cached fetched output.\n- Bare `host:port` URLs collide with the selector grammar — add a trailing slash before the selector: `https://example.com/:80`.\n\n# Internal URIs\n\n`agent://`, `artifact://`, `rule://`, and `local://.md` resolve transparently and accept the same line selectors as filesystem paths. Use `artifact://` to recover full output that a previous bash/eval/tool result spilled or truncated.\n\nBundled skills have no filesystem home, so the skill tool and skill discovery report them as `embedded:gjc/skills//SKILL.md`; read that identifier verbatim.

In CI environments with scheduler variation, the recovery loop could timeout waiting for the timer to fire, even though tools had already drained. The fix adds a wakeOnToolDrain() method to PromptDeadlineManager that is called immediately when the pending tool count transitions from non-zero to zero. This ensures the deadline recovery retries publication without waiting for the scheduled 1-second timer, making the behavior deterministic across different timing conditions.

This created a deadlock where the note-transition-before-persist checkpoint was recorded but note-transition-persisted was never seen. Solution: Use a separate terminalPersistenceChain for truly terminal transitions (when next.terminalAt is set).

However, this change: 1. Failed to fix the original deadline recovery hang in the test 'a captured cancelled end stays private and recoverable while tools are unproven' where persist() would never complete, leaving checkpoints at note-transition-before-persist 2. Regressed the streaming test 'overlapping agent_end waits for in-flight start persist then publishes start before end' The separate chain introduced complexity without solving the underlying deadlock. The real issue is more subtle and requires deeper investigation into store transaction ordering, but the revert restores both tests to passing state. The hang only manifests under CI timing conditions (high contention, slow runners) and appears to involve interactions between the deadline recovery's store operations and the runtime's persistence chain, but was masked rather than fixed by the separate chain approach.

If the manager is rekeyed from E1 to E2 before the queue is drained or the subagent is cancelled, the saved admission endpoint must be used to look up and retire the ownership registration. Previously, #startResume and #retireQueuedOwned tried to resolve the endpoint fresh from the tool lineage, falling back to the manager's current endpoint. After a rekey, this lookup would use E2 instead of E1, missing the registration created at admission and leaving it behind. Now: - Save admissionEndpointId in SubagentRecord.queued - Pass it through to #startResume for valid queue drains - Use it in #retireQueuedOwned for both start failure and cancellation - Add regression test: valid queued resume ownership is preserved across rekey Also clean up #toolsStillPendingOnLastCheck in prompt-deadline-manager's clear() and clearAll() methods.

Under high contention, this could cause the instrumentation callback to interact with microtask scheduling in a way that creates a deadlock in the deadline recovery's persist operations. By moving the 'enqueued' event into the run() function, the instrumentation is now reported AFTER the promise is properly queued, ensuring consistent ordering and preventing race conditions in the promise chain. This applies to all persistence operations in both the runtime and the reconciliation store: persist, transact, transactTerminalScopes, transactTerminalState, and transactTerminalKeys. The fix ensures that the deadline recovery can properly persist terminal transitions without being blocked by timing issues in the instrumentation chain.

When the chain promise was being chained with .then(), the update to the global chain variable could race with the next transact call, creating a situation where a promise could be scheduled but never awaited, leading to a deadlock. The fix ensures that the settled promise is created and assigned to the chain variable atomically before any await operations, preventing the race condition that caused the store.transact() call to hang indefinitely.
