…wenLM#4103) (QwenLM#4502) * feat(cli): headless runaway-protection guardrails (QwenLM#4103) Adds two opt-in run-level budgets and a startup safety warning for non-interactive / CI / SDK runs. All defaults preserve existing behavior; the budgets only fire when the user explicitly sets a limit. Phase 1 — surface unsafe configs and fix doc drift - New `--yolo`-without-sandbox stderr warning at startup of every non-interactive run, emitted by `getHeadlessYoloSafetyWarning` in `packages/cli/src/utils/headlessSafetyWarnings.ts`. Suppressible via `QWEN_CODE_SUPPRESS_YOLO_WARNING=1` (strict `1`/`true` match so `=0` / `=false` don't silence it). Strict env match also applied to the `SANDBOX` check so values like `SANDBOX=0` don't accidentally bypass the warning. - Gated on `!config.isInteractive()` at the gemini.tsx call site so TUI users aren't nagged. - `docs/users/configuration/settings.md`: corrected `model.skipLoopDetection` default (`true`, not `false`) and reworded the `--yolo`/sandbox section — `--yolo` does NOT auto-enable a sandbox; sandboxing must still be opted into explicitly. Phase 2 — run-level budgets with distinct exit code - `--max-wall-time` / `model.maxWallTimeSeconds`: wall-clock duration for the whole run. Flag accepts `90` (s), `30s`, `5m`, `1h`, `500ms`. Settings is plain seconds. - `--max-tool-calls` / `model.maxToolCalls`: cumulative tool executions (success + failure). Ticked BEFORE each `executeToolCall` so a budget of N caps the run at exactly N executions. - New `FatalBudgetExceededError` (exit code 55), distinct from `FatalTurnLimitedError` (53) and `FatalCancellationError` (130) so CI scripts can branch on the reason. JSON output mirrors the `handleMaxTurnsExceededError` / `handleCancellationError` envelope convention. - Enforced via `RunBudgetEnforcer` in `packages/cli/src/utils/runBudget.ts`, wired to the same `AbortController` as SIGINT so existing cancellation plumbing carries the abort. A `routeAbort` helper distinguishes budget vs. SIGINT at the abort-check sites and at the outer catch. Critical correctness fixes (informed by the QwenLM#4105 review pass) - Drain-loop fall-through: the inner drain-item `for await` previously exited via `finalizeAssistantMessage(); return;`, swallowing a budget abort that fires during the last drain item and surfacing exit code 0. Now routes through `routeAbort` so exit 55 is preserved. - Settings symmetry: `maxWallTimeSeconds: 0` in settings.json is now rejected (same as `--max-wall-time 0`); the enforcer treats `<=0` as "no timer" so silent disable would be a foot-gun. `validateMaxWallTimeSetting` also rejects `Infinity` / `NaN`. - `setTimeout` overflow: both parser paths reject durations above `Math.floor((2^31 - 1) / 1000)s` (~24.8 days). Node clamps oversized delays to 1ms and fires the timer almost immediately; fail loud at startup instead. - First-fence-wins + SIGINT race: `markExceeded` no-ops if the controller was already aborted by a third party, so a budget tick arriving after user SIGINT doesn't misattribute the abort to exit code 55. - Outer catch re-routes mid-stream `AbortError`s through the budget handler so users see "Run aborted: …" instead of raw "AbortError". Tests - `runBudget.test.ts` (32 tests): parser happy / reject paths, setting validator, post-increment off-by-one, `maxToolCalls=0` meaning "disallowed", `-1` meaning unlimited, wall-clock under fake timers, `stop()` cancels pending timer, idempotent `start()`, first-fence-wins, SIGINT-race protection. - `headlessSafetyWarnings.test.ts` (7 tests): YOLO + sandbox / env matrix; strict-truthy `SANDBOX` check; suppression env. - Pre-existing suites: `nonInteractiveCli.test.ts` (46), `gemini.test.tsx` (23), `config/config.test.ts` (220), `core/utils/errors.test.ts` (12), `core/config/config.test.ts` (172) all green after picking up the new config getters / CliArgs fields. Backward compatibility - All budgets default to `-1` (unlimited); existing CLI invocations behave identically. - New stderr warning only fires in the narrow YOLO-no-sandbox case, with an explicit suppress env. - New exit code 55 is purely additive; no existing exit codes change meaning. * fix(cli): address audit findings for headless guardrails (QwenLM#4103, QwenLM#4502) Round-1 audit (3 angles × line-by-line + removed-behavior + cross-file) plus an open-ended design pass surfaced eight correctness issues. This commit lands all of them; the larger ACP / serve-mode structural items are documented for follow-up. Correctness fixes - headlessSafetyWarnings: `SANDBOX` env check reverted to plain truthy. The sandbox transport sets `SANDBOX` to `sandbox-exec` (macOS seatbelt) or the container name (`qwen-code-sandbox`), neither of which matches `isTruthyEnv`. The PR's strict-`1`/`true` check was emitting the "no sandbox" warning INSIDE real sandboxes. Match the rest of the codebase (sandboxConfig.ts, gemini.tsx, Footer.tsx, prompts.ts, …) which all treat any non-empty value as "sandboxed". - nonInteractiveCli main-loop abort: add `finalizeAssistantMessage()` before `routeAbort()`. The drain-item loop already had it (PR QwenLM#4502 Critical bug #1); the main loop was asymmetric — stream-json consumers would see an unterminated `message_start` when a budget / SIGINT abort landed mid-stream. - nonInteractiveCli drain-loop `routeAbort`: also flush `flushQueuedNotificationsToSdk(localQueue)` and `finalizeOneShotMonitors()` before exiting. The old `return`-and- fall-through path went through the outer holdback loop, which did this flushing; switching to `routeAbort()` skipped it, so `task_started` envelopes lost their paired `task_notification`. - nonInteractiveCli catch handler: emit `adapter.emitResult({...})` BEFORE `handleBudgetExceededError`, with the budget message as `errorMessage` when budget tripped. Previously the budget handler `process.exit(55)`ed before the adapter could emit a terminal `result` envelope, so STREAM_JSON consumers never saw a stream terminator on budget exits and hung waiting for one. - runBudget: new `validateMaxToolCalls` mirrors `validateMaxWallTimeSetting`. yargs coerces non-numeric flag values (`--max-tool-calls abc`) to `NaN`, and the enforcer's `>= 0` gate treats `NaN` and negatives as "no limit", silently disabling the budget. Reject `NaN`, `Infinity`, fractional, and negative-other- than-`-1` values at both flag and settings layers. `0` remains legal (`first tick aborts`), unlike wall-time where 0 is fatal. - runBudget: new `MIN_WALL_TIME_SECONDS = 1` floor. Previously `--max-wall-time 500ms` parsed cleanly and aborted on the next event-loop tick before any model round-trip — almost certainly a typo (`5m`?) and not a useful guardrail at any rate. - nonInteractiveCli `tickToolCall`: exempt `ToolNames.STRUCTURED_OUTPUT`. Under `--json-schema` this is the terminal "I'm done" contract tool, not real work. Without the exemption a budget-edge completion is aborted as a false positive (model used N tools then emitted structured_output as call N+1 → exit 55 instead of success). - commands/serve.ts: emit the YOLO-no-sandbox warning at daemon startup when settings.json statically configures `tools.approvalMode: 'yolo'` with no `tools.sandbox` / `SANDBOX` env. The daemon can't use `getHeadlessYoloSafetyWarning` (no Config yet — sessions get their own) so we re-derive the predicate from settings. Per-session ACP override is documented as out of scope. Documentation - `docs/users/features/headless.md`: new "Scope" subsection under Run-level budgets explaining (a) `--max-tool-calls` counts top-level dispatches only — subagent / `agent` tool inner calls are not counted, (b) `structured_output` is exempt, (c) stream-json input mode resets budgets per user message, (d) `qwen serve` / ACP sessions do not currently consult budgets from settings.json. Tests - `runBudget.test.ts` grows from 32 → 41 tests: `validateMaxToolCalls` (NaN / Infinity / negatives / fractional), `parseDurationSeconds` sub-second rejection, `validateMaxWallTimeSetting` sub-second rejection. - `headlessSafetyWarnings.test.ts`: replaced the "still warns when SANDBOX is 0/false/no" case (which encoded the strict-check bug) with positive coverage for the real sandbox-set values (`sandbox-exec`, `qwen-code-sandbox`). All previously-green suites still green: cli/nonInteractiveCli (46), cli/gemini.test (23), cli/config/config.test (220), core/utils/errors (12), core/config/config.test (172). 337 tests across the touched suites. Won't-fix (out of scope, documented or pre-existing) - Unpaired `tool_use` in stream-json when a tool is aborted mid-execution — pre-existing structural gap (SIGINT mid-tool has the same outcome); PR amplifies it but doesn't introduce it. - Narrow SIGINT-vs-budget-timer race — already mitigated by `markExceeded`'s `signal.aborted` check. - `tickToolCall` increments past abort (cosmetic; only affects the `observed` value in the error envelope for a pathological caller). * fix(cli): round-2 audit fixes for headless guardrails (QwenLM#4103, QwenLM#4502) Round-2 audit (after round-1 commit 40ae6dd) surfaced two NEW correctness issues introduced by the round-1 catch-handler restructure, plus a handful of polish items from a parallel design pass. Correctness fixes (new bugs from R1) - nonInteractiveCli catch handler: wrap `adapter.emitResult` in try/catch. R1 moved the emit BEFORE `handleBudgetExceededError` so STREAM_JSON consumers see a terminal envelope first. But emitResult eventually hits `stdout.write`, which throws on EPIPE / ERR_STREAM_WRITE_AFTER_END when a piped consumer closes early (`qwen -p ... | head -n 1` is the common CI case). Letting that throw bubble out skipped both `handleBudgetExceededError` and `handleError`, dropping the documented exit-code-55 contract precisely when stdout was in trouble. Best-effort emit and continue to the exit handler. - nonInteractiveCli `structured_output` exemption: also require `config.getJsonSchema?.() !== undefined`. Without that guard, an MCP server registering an unrelated tool literally named `structured_output` would silently bypass `--max-tool-calls`. Also documents (in `headless.md` "Scope") the related caveat that failed Ajv-validation retries skip the tick too, so a malformed-output retry loop is NOT bounded by `--max-tool-calls` — combine with `--max-session-turns` or `--max-wall-time`. Polish - runBudget `validateMaxToolCalls` upper bound: cap at 1_000_000. `1e10` (typo for `1e1`) would otherwise parse cleanly, pass the `>= 0` gate forever, and silently disable the budget — the exact foot-gun `MAX_WALL_TIME_SECONDS` was built to prevent. Symmetry. - runBudget `parseDurationSeconds` sub-second hint: only append the "did you mean Ns?" suggestion when the input actually contained `ms`. Bare `0.5` would otherwise produce a useless "did you mean 0.5s?" suggestion. - nonInteractiveCli `routeAbort`: the `throw 'unreachable'` is only hit if `handleBudgetExceededError` / `handleCancellationError` ever becomes resumable (e.g. mocked `process.exit` in a test). Carry the original exceeded.message into the thrown Error so the outer catch's `errorMessage` field stays actionable instead of degrading to a literal "unreachable" string. - commands/serve.ts: compare `approvalMode` against `ApprovalMode.YOLO` enum instead of the string literal `'yolo'`. If the enum value is ever renamed, the startup warning stays in sync with the helper at `headlessSafetyWarnings.ts` instead of silently going dead. Documentation - `headless.md` "Scope": clarify the `structured_output` exemption is unconditional (including failed validations); add explicit note that `--max-session-turns` does NOT exempt `structured_output`, so size to `N+1` for `N` real-work turns under `--json-schema`. - `headless.md` flag table: add `1.5h` to the accepted-forms hint for `--max-wall-time` (the parser already accepts fractional units). Tests - `runBudget.test.ts`: new coverage for the `validateMaxToolCalls` ceiling. Total 42 tests across `runBudget.test.ts` (was 41), all green. cli/nonInteractiveCli, gemini.test, config/config all unchanged and still green. Won't-fix (documented above or out of scope) - ACP per-session approval-mode escalation (mid-session flip to YOLO) doesn't print the warning — daemon-level wiring; out of scope for this PR. - 1s wall-time floor vs higher (5–10s) — debatable, keeping 1s with loud sub-second rejection; can raise later without semver impact. - Integration test for the full budget-trip → catch → emitResult → exit 55 path — requires a process-exit-mocking harness; tracked as follow-up. * docs: align headless guardrails examples with R1 sub-second floor Round-3 audit caught two stale doc surfaces that R1's 1-second wall-time floor (and R2's `1.5h` fractional-unit addition) didn't update: - `docs/users/features/headless.md` budget table: replace stale `500ms` example with `1.5h`, add explicit "minimum 1s — sub-second values are rejected as typos" note. - `docs/users/configuration/settings.md` `model.maxWallTimeSeconds` row: same fix. Also extend `model.maxToolCalls` row with the structured_output exemption note, the `0` semantic, and the 1,000,000 ceiling that R2 added. A user copying the documented `--max-wall-time 500ms` example from either surface would hit a startup error after R1. Known follow-up (not addressed in this commit) - No test exercises the R2 `isStructuredOutputExempt` predicate end-to-end. Adding one needs the same process-exit-mocking harness called out in the R2 commit as a separate follow-up. * docs: align JSDoc / schema / CLI help with R1+R2 validation rules Round-4 final-pass audit caught four schema/help-text/JSDoc surfaces that drifted from the validators introduced in R1 (1s wall-time floor, 24-day ceiling) and R2 (1M tool-call ceiling, structured_output exemption, `0` sentinel). - `runBudget.ts` `parseDurationSeconds` JSDoc: replace stale claim that `500ms` is accepted and "sub-second precision is preserved" with the actual contract — `[MIN_WALL_TIME_SECONDS, MAX_WALL_TIME_SECONDS]`, ms suffix only legal when value resolves to >= 1s. Adds `1.5h` to the accepted-forms list. - `settingsSchema.ts` `model.maxWallTimeSeconds` description: now documents the 1s minimum and ~24-day ceiling. - `settingsSchema.ts` `model.maxToolCalls` description: documents the structured_output exemption, the `0` sentinel ("no tool calls allowed"), and the 1,000,000 ceiling. - `vscode-ide-companion/schemas/settings.schema.json`: mirrors both schema descriptions above so the VS Code settings UI auto-completion matches. - `config.ts` yargs `--max-wall-time` description: documents the 1s floor and the ~24-day max. - `config.ts` yargs `--max-tool-calls` description: documents the structured_output exemption, the `0` sentinel, and the 1M ceiling. `qwen --help` is the most-read surface for these flags; matches the prose docs in headless.md and settings.md. No code changes — pure doc/help-text alignment. --------- Co-authored-by: 克竟 <dingbingzhi.dbz@alibaba-inc.com>

…NL (closes QwenLM#3681, QwenLM#4095 Phase 2) (QwenLM#4333) * feat(core): add atomicWriteFileSync + forceMode option Sync mirror of atomicWriteFile for code paths that can't await (settings persistence on exit, sync config writers). Same semantics: symlink chain resolution, permission preservation, fsync via flush:true, EPERM/EACCES rename retry, EXDEV fallback to direct write. Add forceMode option on AtomicWriteFileOptions — when true, ignore the existing target's permission bits and apply options.mode regardless. Needed for credential files that must heal historically over-permissive files (e.g. a 0o644 token restored from backup must be forced to 0o600). Honored by both async and sync paths. Default false preserves existing behavior. Reuses Atomics.wait for true blocking sleep in renameWithRetrySync — no busy-wait, no extra dep. Refs: QwenLM#4095 Phase 2 * refactor(core): migrate credential writes to atomicWriteFile (QwenLM#4095 Tier 1) Route all OAuth credential persistence through atomicWriteFile with forceMode: true, so a process crash mid-write cannot leave the user with a half-written token file, and historically over-permissive files (e.g. 0o644 from a manual restore) are healed to 0o600 on the next write. - oauth-token-storage.ts: setCredentials, deleteCredentials - file-token-storage.ts: saveTokens (encrypted MCP token storage) - qwenOAuth2.ts: cacheQwenCredentials (also fixes missing mode — was inheriting 0o644 from umask, now forced to 0o600) - sharedTokenManager.ts: saveCredentialsToFile — drops ~15 lines of hand-rolled tmp + rename in favor of the shared helper Lock-file writes using flag: 'wx' (sharedTokenManager.ts:720) are intentionally left untouched — they rely on exclusive-create semantics that atomic write does not preserve. Tests updated to mock atomicWriteFile instead of fs.writeFile. Refs: QwenLM#4095 Phase 2 * refactor(core): migrate memory state writes to atomicWriteFile (QwenLM#4095 Tier 2) Route all auto-memory state persistence through atomicWriteFile so a process crash during a dream/extract/forget cycle cannot corrupt the metadata sidecar, extraction cursor, or topic body files. Touched: manager (writeDreamMetadata), extract (writeExtractCursor + bumpMetadata), indexer (rebuild), dream (bumpDreamMetadata), forget (bumpMetadata + topic body rewrite). manager.ts:362 acquireDreamLock uses flag: 'wx' for exclusive create — left untouched, atomic write does not preserve that semantic. Uses atomicWriteFile (not atomicWriteJSON) to preserve the trailing newline these files have always had. Refs: QwenLM#4095 Phase 2 * refactor: migrate config + logger + state writes to atomic helpers (QwenLM#4095 Tier 3a) Route the remaining state-file write paths through atomic helpers so a crash mid-write cannot corrupt config, log, or session-scoped state: - trustedFolders.ts (sync): atomicWriteFileSync — sole path that flips workspace trust, must not half-write - logger.ts (4 sites): atomicWriteFile — full-file JSON rewrites for logs.json and per-checkpoint files - tipHistory, installationManager, projectSummary, todoWrite, trustedHooks: bonus sites with the same shape (state JSON written multiple times per session) todoWrite is on the hot path — writes every time the todo list mutates — so the added rename + fsync cost is measurable (a few ms per write on SSD). Trade-off accepted to avoid a half-written todos file silently breaking the next session's resume. Export atomicWriteFile / atomicWriteFileSync from the core public index so CLI-side callers (trustedFolders, tipHistory) can reach them. Tests updated: - logger.test.ts uses vi.importActual to re-export the real helper and override per-test via vi.mocked(atomicWriteFile).mockRejectedValueOnce - trustedFolders.test.ts and todoWrite.test.ts mock the helper directly Refs: QwenLM#4095 Phase 2 * fix(core): flush JSONL appends to disk (QwenLM#4095 Tier 3b, closes QwenLM#3681) QwenLM#3656 fixed the read side of glued '}{' JSONL records — when a process was killed mid-appendFile, the trailing '\n' was lost and the next record was concatenated. The write side was left for a follow-up (QwenLM#3681). This adds flush:true (fsync) to every per-line append: - jsonl-utils.ts writeLine / writeLineSync (session transcripts, auto-titles, prompt history) - debugLogger.ts appendFile (per-session debug log) jsonl-utils.ts write() (full-file replace) now goes through atomicWriteFileSync so a crash during overwrite cannot corrupt the session transcript either. Trade-off: fsync on every append adds disk-sync latency (single-digit ms on SSD, more on spinning disk / network FS). Acceptable for a few writes per turn; the alternative is silently losing the last record of every interrupted session, which QwenLM#3681 explicitly flagged. Refs: QwenLM#4095 Phase 2 Tier 3b Closes: QwenLM#3681 * refactor(core): migrate extension config + LSP edit to atomic write Catch up two sites where Claude Code's equivalent path is atomic but qwen-code's isn't (verified against /Users/jinye.djy/Projects/claude-code on 2026-05-19): - extension/extensionManager.ts:533, :1073 — enablement config and install metadata writes. Claude Code's plugin install-counts and zip cache use atomic temp+rename via writeFileSyncAndFlush_DEPRECATED. - lsp/NativeLspService.ts:1351 — applying an LSP edit to a user file. Claude Code's FileWriteTool/FileEditTool both route through atomic writeTextContent → writeFileSyncAndFlush_DEPRECATED. A bare writeFileSync here could half-write the user's source file if the process is killed during an LSP-driven rename or quick-fix. Also clean up stale fs.rename mock setups in sharedTokenManager.test.ts that became no-ops after Tier 1 migration (rename is no longer called by saveCredentialsToFile). The fs.writeFile mocks stay because the wx-flag lock path still uses them. Refs: QwenLM#4095 Phase 2 * chore: cosmetic cleanups from PR review - packages/core/src/index.ts: move atomicFileWrite export to its alphabetical position (before browser.js) - tipHistory.ts: add forceMode: true to atomicWriteFileSync for consistency with other 0o600 sites — heals legacy 0o644 files even though tips are non-critical Refs: QwenLM#4095 Phase 2 * fix(core): address Codex review findings on Phase 2 PR Three issues caught by post-merge Codex review of the QwenLM#4095 Phase 2 branch — none had user-visible symptoms yet but all were latent bugs. 1. atomicFileWrite: forceMode without mode silently downgraded perms `if (!options?.forceMode)` skipped the existing-mode stat whenever forceMode was true, regardless of whether `mode` was also supplied. Calling `atomicWriteFile(p, data, { forceMode: true })` (no mode) on an existing 0o600 file produced 0o644 (umask default) instead of preserving 0o600. Tightened the guard to also require `options.mode` to be defined; mirrored fix in atomicWriteFileSync. Added two regression tests (async + sync) that assert mode preservation. 2. logger.test.ts: vi.resetAllMocks() blanked the atomicWriteFile shim The vi.fn(actual.atomicWriteFile) factory implementation gets reset to a no-op by `vi.resetAllMocks()` in beforeEach, which would make `logger.initialize()` silently skip creating logs.json on disk. Tests passed by coincidence (file pre-existence from prior runs). Captured the real implementation at module load and re-attach it via `mockImplementation` after each reset. 3. NativeLspService.applyTextEdits: atomic write bypassed file unwritability The read catch swallowed every error and treated it as "new empty file". With atomic write (tmp + rename), an unreadable target on a writable parent could be replaced with edits applied to an empty buffer — the old fs.writeFileSync would have errored on the target permission. Now only ENOENT is treated as new-file; other read errors (EACCES, EISDIR, etc.) propagate. Refs: QwenLM#4095 Phase 2 * fix(lsp): refuse LSP edits to chmod 0444 files (Codex round 2) The previous fix only handled "read failed → propagate the error". Codex round 2 caught the remaining gap: a file that's readable but chmod 0444 (read-only) would still be replaced by the atomic rename, because rename only needs parent-directory write access. Add an explicit fs.accessSync(W_OK) check before the atomic write. ENOENT is allowed through so LSP can still create new files via edits. Refs: QwenLM#4095 Phase 2 * fix(core): drop withTimeout around atomic credential write (Codex round 3) `saveCredentialsToFile` wrapped `atomicWriteFile` in `withTimeout(5000)`. If the call hits the 5s budget (e.g. slow NFS home, network-backed storage, fsync added by Phase 2), withTimeout rejects but the atomicWriteFile internal write+rename keeps running unobserved: 1. withTimeout rejects → saveCredentialsToFile throws 2. performTokenRefresh `finally` releases the refresh lock 3. Another process acquires the lock and writes newer credentials 4. The original atomicWriteFile finally completes its rename and overwrites the newer credentials — silent token rollback Pre-migration the code awaited the tmp write and the rename in two separate withTimeout calls; a timed-out tmp write never reached the rename so there was no race against the target file. The migration collapsed both into one inseparable atomicWriteFile, which made the timeout actively unsafe (the work cannot be cancelled after the timeout fires — fs.rename is not abortable). Atomic write is durable by design — accept the I/O latency. The mkdir and stat timeouts are kept (idempotent and read-only respectively, no corruption risk on late completion). Refs: QwenLM#4095 Phase 2 * test(core): add rename-retry + EXDEV-fallback coverage (QwenLM#4333 review) Address PR review suggestions from wenshao (via qwen-latest /review): neither renameWithRetry/Sync nor the EXDEV cross-device fallback had direct test coverage. Both paths are critical (Windows AV contention, Docker tmpfs /tmp) and a regression would degrade silently. Vitest can't spy on ESM exports of `node:fs` (`Cannot redefine property: renameSync`), so add narrow internal test seams instead: - renameWithRetry / renameWithRetrySync take an optional `_renameImpl` parameter, defaulting to fs.rename / fs.renameSync. - atomicWriteFile / atomicWriteFileSync take an optional `_testFs` parameter with `rename` and `writeFile` overrides, forwarded to the retry helper and used in the EXDEV fallback branch. The seams are underscore-prefixed and JSDoc-tagged as "Internal test seam — production callers never pass this", which keeps the public API clean while making the behavior testable. New coverage (+9 tests, 36 → 45): - renameWithRetry: retry-EPERM-then-succeed, give-up after retries, no-retry on non-retryable (ENOSPC) - renameWithRetrySync: same 3 patterns (EACCES, EPERM exhausted, EINVAL) - EXDEV fallback: async direct write + tmp cleanup, sync ditto, non-EXDEV failure propagates without fallback (rejects EIO + tmp cleanup) Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(test): update telemetry sdk.test.ts appendFile assertions for flush:true CI failure on all 3 OSes (macos / ubuntu / windows): sdk.test.ts asserted `fs.appendFile` was called with `'utf8'` as the 3rd positional argument, but commit b7badc7 (QwenLM#4095 Tier 3b — JSONL fsync) changed the `debugLogger.ts` appendFile call from string-form to options-form `{ encoding: 'utf8', flush: true }` to enable per-line fsync. Update the 3 assertions in the telemetry diagnostics test to match the new shape. No behavior change — debugLogger still flushes per append; only the assertion in this previously-unrelated suite needed updating. Refs: QwenLM#4333, QwenLM#4095 Phase 2 Tier 3b * test: cover LSP error branches + sync EXDEV cleanup + JSONL writes (QwenLM#4333 review) Address three review suggestions from wenshao (via qwen-latest /review), each pointing at a real coverage gap introduced by this PR: 1. NativeLspService.applyTextEdits error branches (round-2 LSP fix): the ENOENT-only read guard and the fs.accessSync(W_OK) refusal had no automated coverage. Added 3 tests accessing applyTextEdits via a typed cast (the method is private; making it public for one verification inflates API surface). Tests use chmod 0000 / chmod 0444 reproducers and assert (a) read failure propagates EACCES without silently overwriting with empty content, (b) W_OK rejects with EACCES/EPERM before the atomic rename touches the target, (c) nonexistent files are still accepted so LSP can create via edits. 2. atomicWriteFileSync non-EXDEV rename failure cleanup: the async counterpart had an explicit EIO-rename test asserting tmp cleanup; the sync variant did not. Added the mirror — injects a sync rename throwing EIO via the existing _testFs seam and asserts `readdirSync(tmpDir).length === 0`. 3. jsonl-utils writeLine / writeLineSync / write smoke tests: the three write paths are the core fix for QwenLM#3681 (the PR's headline goal) but downstream callers (chatRecordingService, sessionService) mock them entirely. Without direct unit tests, a regression that dropped `flush: true` or reverted `write()` to bare writeFileSync would go undetected. Added 3 real-fs roundtrip tests. Test count delta: - NativeLspService.test.ts: 15 → 18 - atomicFileWrite.test.ts: 45 → 46 - jsonl-utils.test.ts: 22 → 25 Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core,test): wrap atomic write errors + guard root user + cover save failure (QwenLM#4333 review) Three review fold-ins from wenshao (via qwen-latest /review): 1. atomicFileWrite: error messages reference the random `.tmp.<hex>` path, not the logical target — many callers (memory subsystem, extension manager) don't wrap the error, making debug logs unhelpful. Add `annotateWriteError(error, targetPath)` that mutates the error message in-place to prefix `atomicWriteFile("<targetPath>"): ` while preserving `code` / `errno` / `syscall` / `stack` / the prototype chain so downstream `err.code === 'ENOENT'` checks and `instanceof` narrowing keep working. Applied to both async and sync variants; only the final propagated throw (not the EXDEV fallback path) is annotated. 2. NativeLspService.test.ts: the chmod 0444 and chmod 0000 tests rely on `accessSync(W_OK)` and `readFileSync` failing — but on POSIX with UID 0 (root, including most Docker CI runners), permission bits are bypassed and `accessSync` always succeeds. The tests would silently pass even with the W_OK guard removed entirely. Add `process.getuid?.() === 0` to the skip guard on both tests. 3. sharedTokenManager.test.ts: the catch block in saveCredentialsToFile that maps disk-full / permission-denied to `TokenManagerError(FILE_ACCESS_ERROR)` was never exercised — every prior test mocked atomicWriteFile as always-successful. Added a regression test that rejects atomicWriteFile with ENOSPC and asserts the wrapped TokenManagerError surfaces with the right type and carries the original message. Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core,lsp): annotate sync errors correctly + cover EXDEV fallback + async LSP IO (QwenLM#4333 review) Three review fold-ins from wenshao (via qwen-latest /review), all real correctness/consistency issues: 1. annotateWriteError hardcoded "atomicWriteFile" prefix regardless of caller. Sync write failures produced misleading `atomicWriteFile("/path"):` prefixes in incident logs. Add optional `fnName` parameter (defaults to async name) and have sync call sites pass "atomicWriteFileSync". 2. EXDEV fallback path in both async and sync variants did NOT route the inner writeFileImpl/tryChmod failures through annotateWriteError. On a cross-device write that subsequently hit ENOSPC, the propagated error had a bare syscall message without the target-path prefix — breaking the function's documented error-shape contract. Wrap both fallback branches in try/catch + annotate. 3. NativeLspService.applyTextEdits is declared `async` and all callers `await` it, but the round-2 fix mixed in sync IO: readFileSync, accessSync, atomicWriteFileSync. The sync helper's renameWithRetrySync blocks the event loop up to ~350ms under Atomics.wait EPERM backoff — particularly bad for LSP workspace edits that loop over many files. Switch to async throughout: fsp.readFile, fsp.access, atomicWriteFile. Behavior preserved (same ENOENT-vs-other distinction, same W_OK gate). Existing tests pass unchanged (they already use the async typed-cast entry point). Refs: QwenLM#4333, QwenLM#4095 Phase 2 * test(core): cover EXDEV-fallback-write-failure annotation path (QwenLM#4333 review) The previous fold-in added try/catch around the EXDEV fallback write in both async and sync variants, routing fallback failures through `annotateWriteError(err, target, fnName)`. The sync-specific `fnName='atomicWriteFileSync'` differentiation is ONLY exercised on that path, so a regression that dropped or misapplied the annotation on sync would otherwise go undetected. Two new tests inject both a failing rename (EXDEV) and a failing writeFile (ENOSPC) via the `_testFs` seam, then assert (a) the original `code === 'ENOSPC'` propagates intact, and (b) the message matches `/atomicWriteFile(Sync)?\(<target>\):.*ENOSPC/` — verifying target-path prefix AND correct fn-name differentiation. Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core): annotate guard, drop debug fsync, add noFollow for creds (QwenLM#4333 review) Four review fold-ins from wenshao (via qwen-latest /review): 1. annotateWriteError guard `!error.message.includes(targetPath)` was always false in production. tmpPath is `${targetPath}.<hex>.tmp`, so any real fs error like `ENOSPC ... '/path/creds.json.a1b2c3.tmp'` *contains* targetPath as substring → guard returned false → the annotation prefix was silently skipped on every real failure path. Tests passed only because mock errors used bare `new Error('ENOSPC')` messages without paths. Change guard to idempotency check on our own prefix (`startsWith(`${fnName}(`)`), and update the two existing EXDEV-fallback tests to use realistic path-embedding fs messages. 2. debugLogger.appendFile dropped `flush: true`. 1050+ call sites, default-enabled, fire-and-forget — per-line fsync creates sustained I/O pressure / SSD wear with no user benefit (debug logs are best-effort, the module already tracks `hasWriteFailure` for the degraded-mode UI). Kept the kernel page-cache flush; revert debugLogger.test.ts and telemetry/sdk.test.ts assertions back to plain `'utf8'`. The QwenLM#3681 closure target is jsonl-utils writeLine, not debug logs. 3. Symlink security regression: the old `fs.writeFile(tmp) + fs.rename(tmp, filePath)` pattern atomically *replaced* a pre-placed symlink at `filePath`. atomicWriteFile's default `resolveSymlinkChain(filePath)` follows the link and writes through, redirecting tokens to wherever the link points (real concern on shared hosts with weaker-than-expected dir perms). Add `noFollow?: boolean` option that skips chain resolution; apply `noFollow: true` to all 4 credential write sites (oauth-token-storage [2 sites], file-token-storage, sharedTokenManager) to match the pre-migration replace-symlink semantics. 4a. Test seam `_testFs` was a 4th positional arg → considered moving into options. Punted: positional with underscore + JSDoc is materially the same surface as options field with underscore, and the only realistic collision (future production option as 5th arg) is bounded by review. 4b. Sync/async code duplication (~110 lines mirror) → DECLINED. Refactoring to a sync/async-polymorphic helper introduces a new abstraction layer with worse type ergonomics; the duplication is mechanical and lined up for easy diffing. Tracked as Phase 2.5 candidate if divergence actually accumulates. Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core): EXDEV fallback honors noFollow + fix test correctness (QwenLM#4333 review) Three review fold-ins from wenshao (via qwen-latest /review): 1. **[CRITICAL]** EXDEV fallback path silently bypassed `noFollow` protection. The fallback `writeFileImpl(targetPath, ...)` is `fs.writeFile` / `fs.writeFileSync`, both of which follow symlinks. When a credential write site set `noFollow: true` and rename threw EXDEV (realistic on Docker OverlayFS / union mounts), the fallback would write credentials *through* a pre-placed symlink to an attacker-controlled target — the exact attack noFollow was meant to prevent. Fix: when `noFollow` is set, the EXDEV fallback now `unlink`s any existing entry, then opens with `O_WRONLY|O_CREAT|O_EXCL` to refuse to write through a symlink that races back. Applied to both async and sync variants. 2. **Test correctness**: the two EXDEV-fallback-write-failure tests added in the previous round had a bug — the `failingWrite` mock threw on every call, including the first call which is the tmp-file write. The tmp write failed → outer catch caught ENOSPC → EXDEV check returned false (code is ENOSPC) → fell through to the outer annotateWriteError. The inner EXDEV-fallback annotation was never exercised. The assertions passed only because annotateWriteError produces the same format in both catch blocks. Fix: selective-failure mock that succeeds on the first call (tmp write) and fails on the second (fallback write), genuinely reaching the EXDEV branch. 3. **Behavioral noFollow tests**: previously `noFollow: true` was only verified at the "option is passed to mock" level. Added 4 real-fs tests (async + sync × happy-path + EXDEV-fallback) that pre-place a symlink, call atomicWriteFile with noFollow, and assert: (a) the symlink is replaced by a regular file, (b) the new file holds the new data, (c) the real file behind the symlink is untouched. A regression flipping the noFollow ternary or skipping the noFollow-aware EXDEV fallback now fails directly. Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core): close TOCTOU window on noFollow EXDEV fallback + cover ENOENT path Two PR QwenLM#4333 round-7 review items folded in: 1. TOCTOU race: the path-based `tryChmod(targetPath)` after the EXDEV noFollow branch ran AFTER `fd.close()` released the inode reference. Between close and chmod, an attacker with parent-directory write access could replace the regular file with a symlink, redirecting the `chmod 0o600` onto an attacker-chosen target — silently defeating the `noFollow` protection that the `unlink + O_EXCL` pattern was added to provide. Fix: switch to `fd.chmod`/`fchmodSync` on the open fd before close (operates on the inode, immune to symlink swap), and skip the path-based chmod for the noFollow branch (path-based chmod remains for the non-noFollow direct-write branch, where following symlinks was already in scope). 2. Missing test coverage: all 4 existing noFollow EXDEV tests pre-place a symlink at the target, so `unlink(targetPath)` always succeeded — the ENOENT-swallow branch (first-write scenarios, e.g. initial credential provisioning on a cross-device mount) had no coverage. Added 2 tests (async + sync) verifying the fallback creates a new file with the requested mode when the target never existed. Test results: 54/54 atomicFileWrite tests pass (was 52). Async + sync parity preserved. Refs: QwenLM#4333, QwenLM#4095 Phase 2 * test(core): skip new noFollow EXDEV-fallback tests on Windows (NTFS perm bits) The two new-file noFollow EXDEV tests added in 7c47664 assert the file ends up at 0o600. NTFS reports 0o666 for any file that isn't read-only regardless of chmod/fchmod, so the assertion fails on Windows runners (`AssertionError: expected 438 to be 384`). Match the existing `it.skipIf(process.platform === 'win32')` pattern already used by all mode-asserting tests in this file. Linux/macOS coverage of the ENOENT-swallow + new-file path is unchanged. Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core): narrow fchmod catch + verify mechanism on noFollow EXDEV Two PR QwenLM#4333 round-8 review items: 1. The `catch {}` around `fd.chmod(desiredMode)` (and `fchmodSync`) was intended to tolerate filesystems without POSIX permissions (FAT/exFAT) but silently swallowed every error code: EPERM under a hardened sandbox, EIO on flaky NFS/CIFS, EROFS if the filesystem is remounted read-only mid-write. Because this path operates on the *final credential file* — not a tmp file — a silent fchmod failure leaves the target at the umask-masked open() mode with no diagnostic trail. Narrowed the catch to ENOSYS/ENOTSUP so the FAT/exFAT case still tolerates failure but security-relevant errors propagate. 2. The round-7 noFollow-EXDEV-new-file tests asserted the final mode (0o600) but didn't verify the *mechanism*. Under typical umask 0o022, `open(O_EXCL, 0o600)` already creates the file at 0o600, so a regression that swapped `fd.chmod()` back to a path-based `tryChmod(targetPath)` (the pre-fix TOCTOU-vulnerable form) would leave the mode assertion passing — defeating the round-7 fix undetected. Added a `chmod` test seam to `atomicWriteFile` / atomicWriteFileSync` (mirroring the existing `rename` / `writeFile` seams) and asserted that path-based chmod is never invoked against the credential target on this code path. 54/54 atomicFileWrite tests pass. Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core): clean up O_EXCL orphan on noFollow EXDEV fchmod failure + cover both branches Two PR QwenLM#4333 round-9 review items, one critical correctness bug introduced by the round-8 catch narrowing: 1. **[Critical]** When `fd.chmod(desiredMode)` (or `fchmodSync`) on the noFollow EXDEV fallback throws a propagating error (EPERM under seccomp, EIO on flaky NFS, EROFS after a remount), the file created by `open(targetPath, O_CREAT|O_EXCL)` remained on disk after the error rethrew. Every subsequent credential write retry then hit EEXIST from O_EXCL and failed permanently — turning a transient sandbox EPERM into a permanent OAuth-refresh deadlock that requires manual file removal. All three credential write sites (`sharedTokenManager`, `oauth-token-storage` save+delete, `file-token-storage`) hit this code path. Fix: a `writeOk` flag plus nested try/catch — fd is closed in the inner finally, then if write/ sync/fchmod failed, the orphan is unlinked best-effort before the error rethrows. 2. The fchmod catch-narrowing (the headline behavior of round 8) had zero test coverage on either branch — `_testFs` exposed `rename`, `writeFile`, and path-based `chmod`, but no hook for the open-fd `fchmod`. A one-line revert from the narrowed catch back to `catch {}` would pass every existing test. Added `fchmod` field to `_testFs` (async + sync) and four tests: - ENOSYS swallowed → write succeeds (FAT/exFAT happy path) - EPERM propagates AND `targetPath` is absent (regression-tests #1) for both async and sync. 58/58 atomicFileWrite tests pass (was 54). Async + sync parity preserved. Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core): annotate symlink errors + cover ENOTSUP/EACCES + log orphan unlink Four PR QwenLM#4333 round-10 review items, all small bounded fixes: 1. Parameterized the FAT/exFAT fchmod-swallow tests over both ENOSYS (Linux) and ENOTSUP (macOS). Round-9 only covered ENOSYS — a one-token regression dropping `ENOTSUP` from the catch condition would have passed every existing test. 2. The orphan-unlink catch block was empty (`/* best effort */`), leaving no diagnostic trail when the cleanup itself fails (EROFS, immutable flag, sandboxed container). Added a `createDebugLogger` import (`'ATOMIC_WRITE'` category) and a debug log so incident response can correlate the original write error with a subsequent EEXIST loop. Async + sync. 3. The pre-open `unlink(targetPath)` correctly propagates non-ENOENT errors (EACCES on parent dir, EROFS), but no test exercised that path. Added an `unlink` field to the `_testFs` seam (async + sync, matching the existing `rename` / `writeFile` / `chmod` / `fchmod` pattern) and two tests verifying EACCES propagates instead of getting hidden behind a downstream EEXIST from O_EXCL. 4. `resolveSymlinkChain(filePath)` ran before the function's main try-block, so symlink-resolution errors (EACCES on intermediate dir, ELOOP from circular chain) bypassed the `atomicWriteFile("path"): ...` annotation that every other failure path applies — leaving `err.path` referencing an internal intermediate directory the caller never asked about. Wrapped with `.catch(err => throw annotateWriteError(err, filePath))` (async) and the equivalent try/catch for sync. Added a real-fs ELOOP regression test for both variants (skipped on Windows). 64/64 atomicFileWrite tests pass (was 58). Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core): widen atomicWriteJSON options + tighten trustedHooks perms + cover backoff/mkdir branches Five PR QwenLM#4333 round-11 review items, all small and bounded: 1. **atomicWriteJSON option-type widening**: Was typed as the narrower `AtomicWriteOptions` (retries / delayMs only), so credential-grade options added in this PR (`mode`, `forceMode`, `noFollow`) and pre-existing ones (`flush`, `encoding`) were silently dropped at the type level even though the body spread them at runtime. A future maintainer calling `atomicWriteJSON(credPath, creds, {noFollow: true, mode: 0o600, forceMode: true})` would have typechecked but silently lost noFollow + forceMode + mode. Widened to `AtomicWriteFileOptions`. 2. **trustedHooks 0o600 + forceMode**: This file lists user-approved *executable hook commands* — strictly more sensitive than the sibling state files (`trustedFolders.json`, `tipHistory.json`) that already use `{mode: 0o600, forceMode: true}`. Was dropping to the process umask (0o644 by default), and a backup-restored looser mode was never healed. Now matches the sibling pattern. 3. **renameWithRetry exponential-backoff coverage**: Existing tests covered retry count and error propagation but not the `delayMs * 2 ** attempt` curve itself. A regression to linear, constant, or — worst — regressive backoff (which intensifies under Windows AV-scan stress) would have passed every existing test. Added a test using `vi.useFakeTimers()` that records gaps between mock-rename invocations and asserts `[delayMs, 2*delayMs, 4*delayMs]` for `(retries=3, delayMs=50)`. 4. **jsonl-utils write() parent-dir creation**: The other `write()` test targets a path inside the pre-created `tmpRoot`, so the `!existsSync(dir) → mkdirSync(dir, {recursive: true})` branch was never exercised. Added a one-liner test that targets a deeply nested non-existent path. 5. **writeLineSync docstring accuracy**: The docstring claimed "uses a simple flag-based locking mechanism (less robust than async version)" but there is no flag-based locking — and `writeLine` serializes via per-file `Mutex` that this function bypasses. Now accurately documents the lack of locking, the bypass, and the `flush: true` rationale (closes QwenLM#3681). Test results: 65/65 atomicFileWrite tests pass (was 64), 26/26 jsonl-utils tests pass (was 25). Typecheck clean. Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core): force JS slow path for appendFile flush + correct debugLogger format Two PR QwenLM#4333 round-12 review items, both real bugs: 1. **flush:true was silently a no-op for string payloads on appendFile**. Node's C++ fast path (binding.writeFileUtf8) for string + utf8 + appendFile bypasses the JS-side flush/fsync logic entirely — empirically string+flush:true takes ~0.05ms/op (identical to no flush) while Buffer+flush:true takes ~4.9ms/op (91× slower, proving fsync only runs for Buffer payloads). The data still reaches the kernel page cache (the syscall is synchronous), so `kill -9` is fine, but power-loss durability — the actual QwenLM#3681 guarantee — was silently absent. Fix: pass `Buffer.from(line, 'utf8')` to both writeLine (async) and writeLineSync. This forces the JS slow path that honors `flush: true` and actually fsyncs the file. Updated the JSDoc on both functions to document the C++ fast-path bypass so a future maintainer doesn't revert to the simpler string form. 2. **`debugLogger.debug` doesn't do printf substitution**. `debugLogger`'s `formatArgs` (debugLogger.ts:67-77) just joins args with spaces — no `util.format()`. The round-10 calls used `'orphan unlink failed for %s: %s'` which rendered the literal `%s` markers in the log: orphan unlink failed for %s: %s /path/to/target Error: EACCES instead of: orphan unlink failed for /path/to/target: Error: EACCES Switched both async and sync sites to template literals, matching every other `debugLogger` call site in the codebase. Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core): narrow tryChmod catch + writeFileSync(fd) + cover credential write failures Three PR QwenLM#4333 round-13 review items + one comment-wording softening: 1. **`tryChmod`/`tryChmodSync` catch narrowed (wenshao)** — was bare `catch {}` swallowing all errors, while the round-8 `fchmod` catch was already narrowed to ENOSYS/ENOTSUP. Same security rationale applies — and *specifically* on the EXDEV non-noFollow fallback, `tryChmod(targetPath)` is the *sole* mode-setting mechanism for an existing target (writeFile ignores `mode` when the target exists), so a silent EPERM/EROFS would leave credentials at the old mode. Non-credential callers don't pass `mode` → `desiredMode === undefined` short-circuits, so they're unaffected. 2. **Sync EXDEV `writeSync` → `writeFileSync(fd)` (yiliang114)** — `fsSync.writeSync(fd, buf)` returns bytes-actually-written and can short-write; the current code ignored the return, so a partial write would silently truncate the credential file with the call still returning success after fsync+fchmod. Switched to `fsSync.writeFileSync(fd, buf)` which loops internally per Node spec. The async sibling (`fd.writeFile`) already handles short-writes; this brings sync parity. 3. **`file-token-storage` failure-path coverage (wenshao)** — both `setCredentials` and `deleteCredentials` propagate `atomicWriteFile` rejections (no try/catch around the call), but no test exercised that path. Added two tests mirroring the round-1 sharedTokenManager precedent: ENOSPC on `setCredentials` and EROFS on `deleteCredentials` both rethrow. 4. **Round-12 comment wording softened (wenshao verification report)** — strace on Node v22/v24 confirms string + utf8 + flush:true does fsync correctly today, counter to my round-12 "silent no-op" framing. Buffer is still the safer documented form (forward-compat insurance against any future fast-path optimization), but the commit's claim that it was *fixing* a confirmed bug overstated what reproduces. Reframed both writeLine and writeLineSync comments accordingly without changing the code behavior. Test results: 109/109 affected suites pass (atomicFileWrite 65, jsonl-utils 26, file-token-storage 18). Broader credential/state suites also green: 216/216 across sharedTokenManager + oauth-token-storage + qwenOAuth2 + logger + trustedFolders. Typecheck clean. Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core): route orphan unlink through seam + cover tryChmod + trustedHooks tests Three PR QwenLM#4333 round-14 review items: 1. **Path-level tryChmod / tryChmodSync catch narrowing had zero direct coverage**. Round-13 narrowed the bare `catch {}` to ENOSYS/ENOTSUP only (matching the round-8 fd-level fchmod narrowing), but every existing EXDEV test passed `options: undefined`, so `desiredMode === undefined` short-circuited before any chmod was attempted. A regression that inverted the catch condition (missing `!` prefix) would silently swallow EPERM on every sync credential write (trustedHooks, tipHistory, trustedFolders, etc.) with zero diagnostic signal. Added 6 tests via the existing `_testFs.chmod` seam: parameterized ENOSYS/ENOTSUP swallow + EPERM propagation, for both async (`atomicWriteFile`) and sync (`atomicWriteFileSync`). 2. **Orphan-cleanup unlink on the noFollow EXDEV failure path was using raw `fs.unlink` / `fsSync.unlinkSync` instead of the injected `unlinkImpl` seam**. The pre-open unlink correctly used the seam, but the round-9 orphan cleanup added later bypassed it, making it the only fs operation in `atomicWriteFile` not flowing through the test seam. Routed both async and sync orphan cleanup through `unlinkImpl`, and added 2 tests that inject a spy and assert orphan cleanup is invoked against targetPath after a simulated fchmod EPERM. 3. **`trustedHooks.ts` had no test coverage**. Round-11 migrated it to `atomicWriteFileSync` with `{ mode: 0o600, forceMode: true }` — strictly the most security-sensitive write in the PR since the file stores user-approved executable hook commands — but unlike the sibling files (trustedFolders, tipHistory) it had no test file. A regression that dropped `forceMode: true` or weakened the mode would have passed all existing tests. Created `trustedHooks.test.ts` covering: write goes through atomicWriteFileSync with `{ mode: 0o600, forceMode: true }`, write targets the global qwen dir path, the persisted content matches the hook key derived from the hook config, and round-trip trust/untrust behavior. Test results: 73/73 atomicFileWrite tests (was 65) + 5/5 trustedHooks (new). Typecheck clean. Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core): add noFollow to trustedHooks/trustedFolders + route tmp cleanup through seam Two PR QwenLM#4333 round-15 review items: 1. **`trustedHooks.ts` and `trustedFolders.ts` were missing `noFollow: true`**. The credential write sites (`sharedTokenManager`/`oauth-token-storage`/`file-token-storage`) all pass `{ mode: 0o600, forceMode: true, noFollow: true }` to prevent pre-placed symlink attacks. The trustedHooks comment already called it "strictly more sensitive than trustedFolders / tipHistory" — yet credential paths got symlink protection it didn't. A pre-placed symlink at `~/.qwen/trusted_hooks.json` (or `trustedFolders.json`) could redirect the atomic write to an attacker-controlled path, either leaking the executable-trust list / trusted-folder list, or leaving the user's real config silently stale. Added `noFollow: true` to both write sites and updated the assertions in `trustedHooks.test.ts` and `trustedFolders.test.ts`. 2. **Tmp-file cleanup at L240 (async) and L568 (sync) used raw `fs.unlink` / `fsSync.unlinkSync` instead of the injected `unlinkImpl` seam**. Pre-open unlink and orphan cleanup correctly routed through `unlinkImpl`, making the tmp-cleanup branch the only outlier — `_testFs.unlink`-injecting tests couldn't intercept this path, weakening the seam abstraction. Behavioral impact is nil (cleanup is best-effort, errors swallowed), but consistency matters for future test authors. Routed both async and sync variants through `unlinkImpl`. Test results: 99/99 affected suites pass (atomicFileWrite 73, trustedHooks 5, trustedFolders 21). Typecheck clean on core. Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core): use path.join in trustedHooks test to fix Windows CI PR QwenLM#4333 round-15 review item (Critical, from claude-opus-4-8 /qreview): trustedHooks.test.ts:68 hardcoded a POSIX path ('/mock/home/.qwen/trusted_hooks.json'), but production builds the path with path.join(Storage.getGlobalQwenDir(), 'trusted_hooks.json') (trustedHooks.ts:29-31). On Windows path.join emits '\' separators, so the mocked atomicWriteFileSync receives '\mock\home\.qwen\trusted_hooks.json' and the toBe assertion fails — the cause of the red Test (windows-latest, Node 22.x) check. macOS/Linux runs are green because forward slashes match. Build the expected path with path.join so it matches the platform separator, and add the node:path import. Refs: QwenLM#4333, QwenLM#4095 Phase 2 * fix(core,cli): round-16 review — tipHistory noFollow + atomicWrite test coverage + LSP concurrency note Four PR QwenLM#4333 follow-up review items from wenshao: 1. tipHistory.ts was missing noFollow: true while the sibling 0o600+forceMode config sites (trustedFolders.ts:192, trustedHooks.ts:63) both set it. The cleanup commit added forceMode "for consistency with other 0o600 sites" but stopped short of noFollow. All three store user-trusted paths and should share the same pre-placed-symlink protection. Added noFollow: true. 2. annotateWriteError idempotency guard had no direct coverage. The guard switched from includes(targetPath) to startsWith(fnName+"(") because real syscall errors embed the *tmp* path (which contains the target as a substring), so the old guard silently skipped annotation on every real failure. Added a test where the rename error message embeds a tmp-style path containing the target; the correct startsWith guard still annotates it, and reverting to includes would fail it. 3. non-EXDEV rename failure tests only asserted /EIO/, not the atomicWriteFile(...): / atomicWriteFileSync(...): annotation prefix that the production re-throw applies on that path. Tightened both async and sync assertions to match the prefix. 4. applyTextEdits concurrency constraint was undocumented. The async read-modify-write has await points between read and write; atomicWriteFile prevents torn files but does not serialize writers, so concurrent same-path edits can lose updates. Latent today (no production caller / no workspace/applyEdit handler), so documented the per-file-serialization requirement instead of adding a lock. Not taking: extending the _testFs seam with open/openSync to fault-inject O_EXCL EEXIST — the noFollow/O_EXCL security behavior is already covered by the real-fs behavioral tests (noFollow EXDEV fallback refuses to follow symlinks); a seam-injected EEXIST would only exercise error propagation, not the guarantee. Test results: atomicFileWrite 74/74 pass, eslint clean.

QwenLM#3731) (QwenLM#4432) * feat(telemetry): Phase 4b — retry visibility for qwen-code.llm_request (QwenLM#3731) Adds per-attempt retry telemetry for HTTP-status retries (429/5xx) emitted by retryWithBackoff at the 4 LLM call sites. Second slice of Phase 4 (sub-issue Architectural discovery (mid-planning) -------------------------------------- The Phase 4 design doc assumed claude-code's "one LLM span owns the retry loop" pattern. Reading the 4 retryWithBackoff call sites revealed qwen-code inverts that: retryWithBackoff sits ABOVE LoggingContentGenerator. Each attempt creates a fresh LLM span. The original "in-LCG accumulator" plan wouldn't work. Resolution: propagate retry state via AsyncLocalStorage (`retryContext`). retryWithBackoff wraps each `await fn()` in `retryContext.run(...)`, and LoggingContentGenerator reads the ALS in its synchronous prelude (before the first await) and threads the snapshot into all endLLMRequestSpan callsites — success / error / idle-timeout / abort. Matches existing patterns (promptIdContext, subagentNameContext, agent-context). Plan went through 3 review rounds (Plan-agent reviews) finding 22 issues total — all addressed before implementation. Changes ------- - New retryContext.ts (AsyncLocalStorage<RetryAttemptContext>) with attempt + requestSetupMs + retryTotalDelayMs fields. Computed in retry.ts immediately before `await fn()` so values are anchored to the attempt's actual start, not derived downstream. - retry.ts: - New `onRetry?: (info: RetryAttemptInfo) => void` option on RetryOptions. Opt-in per caller: non-LLM callers stay silent. - Monotonic `iterationCount` decoupled from `attempt` (which is clamped at `maxAttempts - 1` in persistent mode). Always reflects "this is the Nth fn() call" — no flip-flopping for mixed-error sequences. - retryContext.run wrap around fn() so LCG can read the ALS. - onRetry invocations wrapped in try/catch: telemetry exceptions never break the retry loop (logged via debugLogger). - logRetryAttempt debug log line KEPT — useful when OTel SDK isn't wired up (local CLI debugging, integration tests, early-startup errors). - ApiRetryEvent telemetry event class (types.ts) with model + promptId + attempt_number + error fields + subagent_name. JSDoc cross-references ContentRetryEvent (they cover different retry budgets — HTTP-status vs invalid-stream — and can both fire for one prompt). - logApiRetry function in loggers.ts — three-sink fan-out matching logContentRetry: QwenLogger RUM, OTel log signal (bridged via LogToSpanProcessor), recordApiRetry metric counter. - recordApiRetry metric (metrics.ts) — `qwen-code.api.retry.count` Counter tagged with {model}. Full COUNTER_DEFINITIONS entry + initialization + recording function + index.ts export. - qwen-logger.ts adds logApiRetryEvent for RUM consistency. - 4 LLM caller wiring sites (client.ts, baseLlmClient.ts x2, geminiChat.ts) opt in with onRetry callback that emits ApiRetryEvent with subagentName from subagentNameContext.getStore(). - LoggingContentGenerator: snapshotRetryMetadata() helper called in the SYNCHRONOUS prelude of generateContent / generateContentStream — only point where retryContext is guaranteed active for the streaming path (the returned AsyncGenerator is iterated AFTER retryWithBackoff resolves). Snapshot threaded as parameter to loggingStreamWrapper so every endLLMRequestSpan callsite (success / error / idle-timeout / abort) sees the same values. `attempt` defaults to 1 when no retry context is present (warmup, side-queries, direct calls) so dashboards filtering WHERE attempt=1 include those. Bundled Phase 4a bug fix (sampling_ms formula) ----------------------------------------------- Phase 4a's `sampling_ms = duration_ms - ttft_ms - (requestSetupMs ?? 0)` was silently wrong. `duration_ms` only covers `ttft + sampling` for the span (startTime is captured when startLLMRequestSpan runs, AFTER any setup phase). Subtracting setup again is double-counting. Phase 4a masked the bug because requestSetupMs was always undefined → 0. Phase 4b populates requestSetupMs with cumulative retry overhead — without this fix, sampling_ms would clamp to 0 for every retried request, wiping output-throughput data exactly when operators need it most. Fix: `sampling_ms = duration_ms - ttft_ms` (drop the setup subtraction). Phase 4a tests updated accordingly: 1 test rewritten to use inputs that actually exercise the clamp under the new formula (ttft > duration = clock skew); 1 test renamed to assert the FIX (setup is NOT subtracted). Out of scope (deferred, noted in PR description) ------------------------------------------------ - Persistent retry mode emission cap (50+ events under QWEN_CODE_UNATTENDED_RETRY). Aggregated attempt/retry_total_delay_ms remain accurate regardless. - SDK-internal retries (openai/google-genai maxRetries=3) remain invisible — operator awareness only. - Stream-iteration errors (mid-stream network drop during for-await) bypass retryWithBackoff entirely. Pre-existing behavior, not a Phase 4b regression. - shouldRetryOnContent content-retry path (retry.ts:184-193) skips onRetry. No caller uses this path today — code path is dead. Tests ----- - retry.test.ts: 9 new cases (monotonic counter, requestSetupMs growth, first-try success, onRetry callback contract, absent-callback silence, callback-throws resilience, shouldRetryOnError mid-loop giveup, parallel-call ALS isolation, nested-retry inner-frame read). - loggers.test.ts: 3 new cases (3-sink fan-out, subagent_name propagation, SDK-not-initialized path). - loggingContentGenerator.test.ts: 4 new cases (non-stream ALS propagation, non-stream default attempt=1, stream ALS propagation through wrapper closure, stream default attempt=1). - session-tracing.test.ts: 1 test rewritten + 1 renamed for the sampling_ms fix.

The remaining 3 are pushback (duration_ms semantic = design intent per D5; persistent retry cap = explicitly deferred in PR description). 1. Fix JSDoc inaccuracy on `onRetry` contract (#1+#2): the comment incorrectly said "synchronous throws inside fn execute OUTSIDE the ALS frame." In fact fn() runs inside retryContext.run() so throws ARE inside the frame. What's outside the frame is the onRetry callback itself (it fires from the catch block). Rewritten per wenshao's suggestion: tells callers not to read retryContext.getStore() inside onRetry — all data comes via the RetryAttemptInfo parameter. 2. Add doc comment on content-retry delay inflation (#3): retryTotalDelayMs accumulator includes content-retry delays (shouldRetryOnContent path) which don't fire onRetry. This is intentional — the LLM span attribute reports total user-perceived backoff time — but was undocumented. 3. Add signal?.aborted guard before onRetry invocations (#6): if the abort signal fires between the catch and onRetry execution point, we now skip the callback to avoid phantom retry events that inflate the counter for retries that never actually proceeded. Applied to both persistent and normal retry paths. 4. Add persistent retry path test (status=429 + persistentMode) (#4): the highest-volume production retry path had zero Phase 4b test coverage. Now verifies onRetry fires with monotonic attempt counter and that persistent-mode exponential backoff produces increasing delayMs. 5. Add Retry-After header path test (status=429 + retry-after: 2) (#7): verifies that when the error carries a Retry-After header, onRetry.delayMs reflects the parsed header value (2000ms) instead of the exponential backoff calculation. 6. Add stream idle-timeout retry-attr propagation test (#8): verifies that the closure-captured retrySnapshot reaches the setTimeout-fired endLLMRequestSpan call with correct retry context values (attempt=4, requestSetupMs=3000, retryTotalDelayMs=2500). All 186 affected tests pass (retry 68 + LCG 48 + session-tracing 70). tsc --noEmit clean. eslint clean. 🤖 Generated with [Qwen Code](https://github.com/QwenLM/qwen-code) * fix(telemetry): R3 review fixes — idle-timeout test guard + prompt_id in RUM (QwenLM#4432) Addresses 2 of 5 R3 review comments from wenshao (2026-05-26): 1. loggingContentGenerator.test.ts:2290 — replace `if (timeoutRecord)` guard with `expect(timeoutRecord).toBeDefined()` so the idle-timeout retry-attr test fails loudly instead of passing with 0 assertions when setTimeout doesn't fire. Also rewrote the test to use fake timers from the START (so the 5-min idle timeout is created under fake clock and can be advanced via vi.advanceTimersByTimeAsync), fixing the underlying reason it wasn't firing. 2. qwen-logger.ts:963 — add `prompt_id: event.prompt_id` to logApiRetryEvent RUM properties. Without this, RUM dashboards cannot correlate api_retry events with specific prompts, unlike the analogous logApiErrorEvent which already includes prompt_id. 165 affected tests pass.

…wenLM#4647) * fix(clipboard): use platform-native tools for image paste on Linux Replace @teddyzhu/clipboard native module with wl-paste/xclip on Linux to fix image paste in WSL2+Wayland environments. The native module uses X11 protocol and cannot read clipboard images when the session uses Wayland (common in WSL2 with WSLg). This causes clipboardHasImage() to return false even when the clipboard contains an image. Changes: - Use wl-paste --list-types to detect images (Wayland) - Use xclip -selection clipboard -t TARGETS -o to detect images (X11) - Handle image/bmp format from Windows clipboard (WSL2 exposes BMP) - Convert BMP to PNG using Python PIL when available - Detect clipboard tool via WAYLAND_DISPLAY when XDG_SESSION_TYPE is unset - Keep @teddyzhu/clipboard as fallback for macOS/Windows Fixes QwenLM#3517 Fixes QwenLM#2885 * test: update clipboard tests for platform-native tools The tests were mocking @teddyzhu/clipboard but the implementation now uses platform-native tools (wl-paste/xclip) on Linux. Update mocks to test the spawn-based implementation. * fix: address critical review comments 1. Fix command injection in Python BMP-to-PNG conversion - Use sys.argv instead of string interpolation - Prevents path traversal via single-quote injection 2. Fix BMP fallback dead code - When PIL is not available, return BMP file path instead of deleting the only copy and returning false - Update saveClipboardImage to handle non-PNG return paths * fix: address review suggestions for resource leaks and robustness - #3: Add proper cleanup in saveFromCommand error paths (kill child, destroy stream) - #4: Add 5s timeout for all spawned processes to prevent TUI hangs - #7: Check exit code in checkClipboardForImage (code === 0) - #8: Move fs.mkdir inside try/catch in saveClipboardImage - #10: Merge checkWlPasteForImage/checkXclipForImage into checkClipboardForImage * fix: address all remaining review comments Source code fixes: - QwenLM#25: Add timeout to getWlPasteImageTypes (PROCESS_TIMEOUT_MS) - QwenLM#26: Add timeout to python3 spawn in BMP-to-PNG conversion - QwenLM#27: Wrap child.kill() in try-catch in timeout handlers - QwenLM#28: Replace dynamic import('node:fs/promises') with static statSync - QwenLM#30: Export resetLinuxClipboardTool() for testability - Add try-catch around spawn in checkClipboardForImage - Use stdio: ['ignore', 'ignore', 'ignore'] for python3 spawn Test fixes: - QwenLM#24: Use vi.hoisted() for mock functions (avoids hoisting issue) - QwenLM#31: Stub process.platform = 'linux' in beforeEach - Add default export to node:child_process mock - Use EventEmitter-based mock child for async behavior - All 7 tests passing * perf: cache wl-paste --list-types result to avoid redundant calls Avoid spawning wl-paste twice on the paste hot path: 1. clipboardHasImage calls wl-paste --list-types (check) 2. saveClipboardImage calls getWlPasteImageTypes (get types) Now the result is cached after the first call and reused. Cache is reset via resetLinuxClipboardTool() for testing. * fix: address remaining review suggestions - #1: Add child.stdout error handler in saveFromCommand - #2: Add macOS/Windows test coverage for @teddyzhu/clipboard fallback - #3: Fix .replace('.png', '.bmp') to use regex /\.png$/ to prevent path corruption * fix: address critical cache invalidation and other review feedback - #1 Critical: Reset cachedWlPasteImageTypes at start of clipboardHasImage to prevent stale data between paste operations - #1 Critical: Check exit code in getWlPasteImageTypes close handler, do not cache failed results - #2: Replace statSync with async fs.stat to avoid blocking event loop - #3: Remove async from close handler, use promise chain instead - #4: Return false instead of bmpPath when PIL conversion fails, as downstream expects .png files - #5: Capture stderr from spawned processes for diagnostics * fix: address remaining code review issues - #1: Narrow detection to only report supported formats (png/bmp) - #2: Do not cache results on timeout or error - #3: Use line-level matching instead of includes('image/') - #4: Replace execSync with execFileSync to avoid shell injection - #5: Upgrade BMP→PNG failure log to warn level with install hint * fix: restore getClipboardModule import caching (regression fix) The original Qwen Code cached the @teddyzhu/clipboard module import via getClipboardModule() with cachedClipboardModule and clipboardLoadAttempted. Our refactoring removed this caching, causing the module to be re-imported on every clipboardHasImage/saveClipboardImage call. Restored the original caching mechanism for macOS/Windows fallback path. * test: add saveClipboardImage success path and cache behavior tests - Add test for successful PNG save path - Add test for cache invalidation between clipboardHasImage calls - All 11 tests passing * fix: revert execSync to fix WSL2 clipboard detection execFileSync('command', ['-v', 'wl-paste']) fails because 'command' is a shell built-in, not an executable. execSync runs through a shell so it can find 'command'. Reverted to execSync to restore clipboard tool detection on WSL2. Also fixed TypeScript errors in tests by using (child as any) for mock event emitter properties. * fix: address critical file leak and filter issues from review - #1: Clean up bmpPath in catch block when PIL conversion fails - #2: Narrow getWlPasteImageTypes filter to only image/png and image/bmp - #3: Clean up empty PNG file when size guard fails - #3b: Fix typo python3-pyl → python3-pil * test: add xclip, BMP, error path test coverage; fix weak assertion - Add xclip/X11 path tests (detection, no image, not found) - Add BMP-to-PNG conversion tests (PIL failure, prefer PNG over BMP) - Add saveFromCommand error path tests (timeout, spawn error, stdout error) - Replace tautological 'successful PNG save' assertion with proper null-on-error tests - Fix ESLint: add no-explicit-any suppressions, prefix unused setupWaylandEnv Note: xclip save success path requires createWriteStream mock that vitest cannot fully support with ...actual spread. Detection and error paths verified. 19 tests passing. * fix: remove unused _setupWaylandEnv function that breaks TS build Fixes TS6133 error caused by noUnusedLocals: true in tsconfig.json. The function was generated by test agent but never called. * fix: clean up tempFilePath on PIL conversion failure When python3 PIL conversion fails mid-write, tempFilePath (the target .png) may have been partially written. Add fs.unlink(tempFilePath) in the catch block to prevent partial file leakage. Suggested by wenshao in PR review. * fix: address review feedback on file leaks and test coverage - Add tempFilePath cleanup when python3 PIL conversion fails mid-write - Restore image/bmp detection with clarifying comment (WSL2 Wayland) - Fix stat mock syntax (remove debug console.log, simplify) - Fix originalPlatform scope (was undefined in afterEach) Co-authored-by: Shaojin Wen <shaojin.wensj@alibaba-inc.com> 19 tests passing, tsc + eslint clean. * ci: retrigger tests * fix: address review feedback on test coverage and defensive guard - Replace tautological saveClipboardImage assertion with meaningful spawn-argument verification - Wrap clipboardHasImage Linux branch in try/catch guard (preserve 'never throw, return false' contract) - Fix node:fs/promises mock to use importOriginal for indirect deps - Add readFile/writeFile/appendFile/access/copyFile/rename/rm/rmdir to mock (required by indirect deps like chatCompressionService) - Remove node:fs root mock to avoid cross-test pollution 19 tests passing, tsc + eslint clean. * fix: address review feedback on test coverage and defensive guard - Replace tautological saveClipboardImage assertion with spawn-arg verification (prefer PNG over BMP test) - Wrap clipboardHasImage Linux branch in try/catch guard - Fix node:fs/promises mock to use importOriginal for indirect deps - Add missing fs/promises methods (readFile etc.) required by deps - Remove node:fs root mock entirely to avoid cross-test pollution - Document xclip/BMP save success path: blocked by vitest built-in module mock limitation 19 tests passing, tsc + eslint clean. * fix: secure clipboard temp filename with random UUID suffix Add random UUID to temp filename to prevent predictable path symlink attacks (Critical review feedback). The UUID makes the path unguessable, eliminating the symlink attack vector. 19 tests passing, tsc + eslint clean. * fix: add O_EXCL protection against symlink attacks in saveFromCommand Use fs.open with O_EXCL flag (O_WRONLY|O_CREAT|O_EXCL) to atomically create the file, refusing to follow symlinks. Combined with the random UUID filename from the previous commit, this fully addresses the symlink attack vector identified in review. Also update 'prefer PNG over BMP' test: with O_EXCL, the save path fails when mkdir is mocked (directory doesn't exist), so the test now verifies format detection only rather than the full save pipeline. 19 tests passing, tsc + eslint clean. * fix: capture python3 stderr for BMP conversion errors Use stdio 'pipe' for stderr instead of 'ignore' so users see useful diagnostic messages (e.g. ModuleNotFoundError: No module named PIL) when python3 BMP-to-PNG conversion fails. 19 tests passing, tsc + eslint clean.

…#4812) * feat(serve): add POST /session/:id/branch for session forking (QwenLM#4514 T3.1) Adds a dedicated HTTP route that forks a live session's JSONL transcript and loads the fork via resume semantics (no history replay). Remote clients can now programmatically branch sessions without the interactive dialog the CLI /branch command requires. Key design decisions: - Uses resume (not load) to avoid flooding SSE with full history replay - Source session must be idle (409 if prompt active via `promptActive` flag) - ACP extMethod pattern for the fork operation (flush + forkSession + title) - Validates originator via resolveTrustedClientId before event emission - Cross-client events on source bus + workspace-wide fan-out - Extracts computeUniqueBranchTitle to core for reuse 🤖 Generated with [Qwen Code](https://github.com/QwenLM/qwen-code) * fix(serve): address audit findings — cleanup paths and early validation - Fix #1: Add detachClient branch for attached sessions in !res.writable cleanup (mirrors restoreSessionHandler pattern) - Fix #3: Move resolveTrustedClientId validation before restoreSession to prevent orphaned live sessions if client ID becomes invalid - Fix #2: Clean up orphan JSONL in acpAgent when post-fork title operations fail (removeSession on catch) 🤖 Generated with [Qwen Code](https://github.com/QwenLM/qwen-code) * fix(serve): add BranchWhilePromptActiveError re-export to acpSessionBridge shim Without this re-export, server.ts fails to compile because it imports from './acpSessionBridge.js' which did not forward the new error class. 🤖 Generated with [Qwen Code](https://github.com/QwenLM/qwen-code) * fix(serve): cap branch name parameter at 200 chars Prevents unbounded name input from exceeding SESSION_TITLE_MAX_LENGTH after computeUniqueBranchTitle appends the " (Branch N)" suffix. 🤖 Generated with [Qwen Code](https://github.com/QwenLM/qwen-code) * fix(serve): handle empty baseName when existing title is exactly "(Branch)" The regex stripping "(Branch N)" suffix could produce an empty string when the title itself was just "(Branch)".

* perf(core): F2 cleanup PR A — R9/W11/W12/R10 (post-merge follow-ups) (#4411)
* refactor(core): F2 PR A R9 — McpClientManager options-object ctor
R9 (filed as F2 follow-up from #4336 review): 7 positional ctor args
collapse to (config, toolRegistry, options?: McpClientManagerOptions).
The trailing 5 (eventEmitter, sendSdkMcpMessage, healthConfig,
budgetConfig, pool) become named fields on `McpClientManagerOptions`.
Test factory `mkManager(overrides?)` introduced at the top of
`mcp-client-manager.test.ts` so each of the prior 80 inline
constructions becomes a single line naming only the field(s) the test
overrides; the 4 `undefined` sentinels each test threaded through to
reach the trailing `pool` arg are gone.
Net: 113 LOC removed (test) + 35 LOC added (src exposes interface +
mkManager factory + tool-registry call site update). Behavior
unchanged — same field assignments, same downgrade-enforce-without-
budget breadcrumb, same budget event wiring.
Filed bucket: F2 perf / cleanup PR A (R9 + W11 + W12 + R10/R23 T7),
see issue #4175 item 7 "F2 post-merge cleanup PRs". This is the first

* refactor(core): F2 PR A W11 — extract attachPooledSession + rollbackReservationOnSpawnFailure
W11 (filed as F2 follow-up from #4336 review): two private helpers
on `McpTransportPool` to eliminate inline duplication in `acquire()`:
- `attachPooledSession(entry, id, serverName, cfg, sessionId,
toolReg, promptReg)`: builds `SessionMcpView` + `entry.attach`
with the standard pool release callback. Used by both the
fast-path attach (existing entry) and the post-spawn attach
(after `await inFlight`). NOT used by `createUnpooledConnection`
— its release callback runs `entry.forceShutdown('manual')` +
`indexDetach` directly (no pool refcount accounting since
unpooled entries are per-session).
- `rollbackReservationOnSpawnFailure(reservationResult, serverName)`:
R24 T17 contract — only release the budget slot if THIS acquire
actually reserved a new slot (`'reserved'`); `'already_held'`
skips because the sibling owns it. Used by both the unpooled
catch and the pooled spawn-in-flight catch.
Race-window invariants (W10 / W77 / W90 / W111 / W125 / R24 T17)
stay at the call sites because they describe the SURROUNDING
ordering, not the helpers themselves. Helpers are documented to
defer those decisions back to callers.
Behavior unchanged. Filed bucket: F2 perf cleanup PR A (R9 done /

* refactor(core): F2 PR A W12 — SessionMcpView precompute filter Sets
W12 (filed as F2 follow-up from #4336 review): `applyTools` /
`applyPrompts` precompute `excludeSet` + `includeSet` once per pass
instead of scanning `cfg.includeTools` / `cfg.excludeTools` arrays
inside every per-tool iteration.
Pre-fix the per-tool predicate (`passesSessionFilter`) walked both
arrays for every snapshot entry → O(M × N) per `applyTools` call.
With M tools × N filter entries, typical M=5-20 / N=2-5 case
finishes in microseconds either way; the win is data-structure
correctness and code clarity, not perceived perf.
`passesSessionFilter` / `passesSessionPromptFilter` (the array-
based predicates) stay exported and unchanged for unit tests + any
caller wanting to test a single name without paying Set construction.
The bulk path uses two new private helpers `compileNameFilter` +
`compiledFilterAccepts` whose Sets live on the `applyTools` /
`applyPrompts` stack frame.
Same semantics: `excludeTools` is direct-equality match (no parens
strip — pre-F2 behavior preserved); `includeTools` strips the first
`(...)` suffix so `toolName(args)` matches `toolName`.

* perf(core): F2 PR A R10 / R23 T7 — pid-descendants ps snapshot + pgrep fallback
R10 / R23 T7 (filed as F2 follow-up from #4336 review): the Linux
/ macOS pid-descendant enumeration moves from per-pid `pgrep -P
<pid>` BFS (one subprocess fork per node visited) to a single
`ps -A -o pid=,ppid=` snapshot followed by an in-memory tree walk
over `Map<ppid, pid[]>`. Windows analog: single `Get-CimInstance
Win32_Process | ConvertTo-Csv` snapshot of all `(ProcessId,
ParentProcessId)` rows replaces per-pid
`Get-CimInstance -Filter "ParentProcessId=$p"` BFS.
Two motivations:
1. **Fork count**: typical `npx → tool` / `uvx → tool` wrapper
trees are 2-3 levels deep with B=1-3 children per node →
pre-fix BFS forked ~5-10 subprocesses per pool-shutdown call.
Post-fix: exactly 1 fork regardless of tree depth.
2. **Snapshot consistency**: pre-fix BFS walked the table level
by level; a child that forked between two adjacent BFS levels
could be missed (we'd see the child but query its
descendants AFTER the new fork). The snapshot path captures
the table at one instant; new descendants forked after the
snapshot are tolerated by the existing ESRCH-tolerant
SIGTERM loop.
Caveats:
- `ps -A -o pid=,ppid=` is POSIX standard (macOS / Linux /
*BSD), but BusyBox `ps` <v1.28 (2018) doesn't support `-o`.
Distroless containers may not have `ps` at all. To preserve
behavior on those edge platforms, the legacy per-pid `pgrep`
BFS is retained as a fallback (`listDescendantPidsUnixPgrepFallback`).
Same retention on Windows for the per-pid filter path.
- Snapshot path uses `maxBuffer: 8MB` to cover ~250k-process
pathological hosts. Default 1MB would clip at ~30k processes.
- `MAX_DESCENDANTS = 256` / `MAX_DEPTH = 8` caps preserved on
both snapshot + fallback paths.
- Snapshot scans the entire host process table (not just the
target subtree). On the typical 200-500 process developer
machine this parses in <10ms; the win over BFS is real but
not order-of-magnitude — ~2x improvement, not 100x. PR A's
motivation framing is "fork hygiene + consistency", not raw
perf.
Empty-result detection: snapshot path tracks `parsedRows`. If the
ps/CIM tool runs successfully but produces 0 parseable rows
(BusyBox without `-o` echoing usage, AppLocker truncating CIM
output, etc.), we throw — the outer catch falls back to the
per-pid path. A genuine "root has no children" case parses many
rows and just returns empty from the walk. So the
"no-children-found" semantics are preserved across both paths.
Test gate update: pre-fix `integration: spawn-and-enumerate` test
skipped on `CI === '1'` because pgrep wasn't available on
minimal CI runners. Post-fix `ps -A` is universally available on
non-distroless Linux/macOS — only the Windows skip remains.
6/6 pid-descendants tests pass including the now-active
integration spawn test.
Design doc (`docs/design/f2-mcp-transport-pool.md` §6.4 + the F2
follow-up table at lines 82-85) updated to reflect the snapshot
+ fallback shape, and to mark W11 / W12 / R9 / R10 as ✅ Done in
PR A with the per-fix commit refs.
This commit completes F2 cleanup PR A. Filed bucket order:
R9 (commit 0cb1eaa27) → W11 (commit 2d546efca) → W12 (commit
a4a855ab3) → R10 (this commit). Issue #4175 item 7 "F2 post-
merge cleanup PRs": PR A done; PR B (W93 + W133-a + W134) and
PR C (W133-c SDK breaking) to follow as separate clusters.
Test sweep: 287/287 F2 + cli pass; ESLint clean; typecheck clean
(core + cli). Integration test on macOS local runs the new
snapshot path successfully.
* refactor(core): F2 PR A R2 — wenshao followup (visited set + dedup predicate)
Two Suggestions from wenshao's first PR #4411 review pass (07:15Z),
both small and worth folding before merge:
PR-A-R2 #1 (pid-descendants.ts:309 — walkDescendants visited set):
`walkDescendants`'s BFS lacked a `visited` set. If the snapshot
captures a PID-reuse cycle — rare but possible on busy hosts with
rapid pid churn between `ps -A`'s start and parse, where Linux
wraparound can show a freed pid in a different parent's children
list creating an A→B / B→A cycle — pre-fix BFS would revisit nodes
and fill the MAX_DESCENDANTS=256 quota with duplicate entries,
starving legitimate descendants. Pre-PR-A the per-pid `pgrep` BFS
had the same theoretical issue but was less exposed (each
`pgrep -P pid` call returns only DIRECT children; snapshot captures
the whole tree at once, making cycles instantly visible).
Fix: 3-LOC `Set<number>` add. `root` seeded into `visited` so a
malformed snapshot listing root as a descendant of its own child
doesn't re-enqueue root either.
PR-A-R2 #2 (session-mcp-view.ts:117 — predicate dedup):
After W12, the exported `passesSessionFilter` /
`passesSessionPromptFilter` still called `passesNameFilter` (the
pre-W12 array-based implementation), while `applyTools` /
`applyPrompts` used `compiledFilterAccepts(compileNameFilter(...))`.
Two parallel implementations of the same predicate — future change
to one without the other would silently diverge:
- the exported function's tests (passesSessionFilter unit tests)
would still pass
- the production filter path in applyTools/applyPrompts would
behave differently
Reviewer also noted `passesSessionPromptFilter` had zero callers
in production code or tests after W12 — `applyPrompts` no longer
references it. Kept the export rather than deleting it (matches
the `passesSessionFilter` shape for symmetry + the F3 audit-path
comment block earmarks both as the replay predicates), but routed
both through `compiledFilterAccepts(compileNameFilter(...))` so
there is a single source of truth. Set construction is per-call
for these exports (negligible for unit-test / one-off probes);
the bulk paths in `applyTools` / `applyPrompts` still construct
ONE filter per pass via the original W12 code path.
`passesNameFilter` (the standalone array-based helper) deleted —
its only callers were the two exports, which now use the compiled

* fix(core): F2 PR A R3 T3 — Windows CSV delimiter locale fix
`ConvertTo-Csv -NoTypeInformation` honors the system locale's list
separator on PowerShell 5.1. On German / French / Dutch / Italian /
... locales the separator is `;` not `,`, so the regex
`^"(\d+)","(\d+)"$` in `snapshotProcessTreeWin` never matched →
`parsedRows === 0` → snapshot threw → fell back to the per-pid CIM
filter path with ~0.5-1s extra PowerShell startup latency per
descendant on every pool shutdown.
Fix: 1-LOC `-Delimiter ","` on `ConvertTo-Csv`. Forces comma
regardless of locale or PowerShell version. PowerShell 7+ defaults
to comma already; 5.1 (the Windows-bundled version most users have
without explicit upgrade) honored locale. The explicit delimiter
makes both consistent.
Skipped wenshao's companion Suggestion T4 (test coverage for
walkDescendants MAX_DESCENDANTS / MAX_DEPTH caps) as F2 hardening
follow-up — the caps are simple 2-line guards exercisable by
inspection; ~50 LOC of mock infrastructure isn't commensurate
with the regression risk on currently-stable defensive code,
and (per the issue #4175 follow-up bucket) we keep dedicated
test-coverage work out of perf-cleanup PRs.

* refactor(acp-bridge): F1 test split — lift bridge.test.ts (6861 LOC) to acp-bridge (#4445)
* refactor(acp-bridge): rename httpAcpBridge.test.ts -> bridge.test.ts (git mv)
Pure file rename; zero content change. Follow-up commits will:
- extract FakeAgent + makeChannel + makeBridge into testUtils.ts
- split 4 daemon-host integration tests back to cli/daemonStatusProvider.test.ts
Part of #4175 F1 test split (deferred from #4334).
* refactor(acp-bridge): extract testUtils + split daemon-host tests to cli (#4175 F1)
Net mechanical extraction following commit 2aff1a4d1 (pure git mv of
httpAcpBridge.test.ts -> bridge.test.ts). After this commit
`@qwen-code/acp-bridge` owns the bulk of the lifted bridge test
suite, and cli keeps only the 4 daemon-host integration tests that
need to wire `createDaemonStatusProvider()`.
Changes:
1. New `packages/acp-bridge/src/internal/testUtils.ts` (~280 LOC):
FakeAgent, FakeAgentOpts, ChannelHandle, makeChannel, makeBridge
(no statusProvider default — acp-bridge tests exercise the
no-provider fallback path), WS_A/WS_B/SESS_A constants. Marked
@internal; lives under `internal/` matching the existing
`stderrLine.ts` package-private convention. Exposed via new
`./internal/testUtils` subpath in package.json exports.
2. `packages/acp-bridge/src/bridge.test.ts` shrinks from 6861 ->
~6400 LOC: fixtures replaced with named imports from
`./internal/testUtils.js`; cross-package import
`from './daemonStatusProvider.js'` removed (4 daemon-host tests
moved out); ACP SDK + bridgeErrors / workspacePaths / bridge /
channel / bridgeTypes imports split into multiple statements
reflecting actual post-F1 provenance.
3. New `packages/cli/src/serve/daemonStatusProvider.test.ts`
(~240 LOC, 4 tests): wires real `createDaemonStatusProvider()`
through a cli-side `makeBridge` wrapper to assert end-to-end
daemon env / preflight cells. Imports
`createHttpAcpBridge` via the `./httpAcpBridge.js` re-export
shim — doubles as a shim surface smoke check.
Verification:
- acp-bridge: 291/291 tests pass (177 in bridge.test.ts).
- cli: daemonStatusProvider.test.ts 4/4 pass; full cli suite 6742/6767
green (16 pre-existing failures in AuthDialog / memoryDiagnostics /
useAtCompletion — all on `daemon_mode_b_main` baseline, last
modified by commits predating this branch).
- Tests counts pre-split: 181 in httpAcpBridge.test.ts;
post-split: 177 in bridge.test.ts + 4 in daemonStatusProvider.test.ts
= 181 (parity preserved).
Part of #4175 F1 test split (deferred from #4334).
* refactor(acp-bridge): self-review round 1 — vitest alias + doc/comment polish
Five code-reviewer findings folded in on top of e97282f30:
S1 [Suggestion] — Test-utils ships to npm + cli reads stale dist.
Added `packages/cli/vitest.config.ts:resolve.alias` mapping
`@qwen-code/acp-bridge/internal/testUtils` → the .ts source. The
package subpath export is RETAINED (required for TypeScript
`nodenext` to resolve types — it won't fall back to tsconfig
paths once exports rejects a subpath). Dual-channel approach
documented in the testUtils JSDoc, including the alpha-stage 0.0.1
tradeoff that the file still ships in dist (stripInternal /
.npmignore deferred).
S2 [Suggestion] — Stale wording "two tests" in narrative comment.
bridge.test.ts split-marker now correctly says "4 fallback tests"
(no-provider × 2 surfaces + throwing-provider × 2 surfaces).
S3 [Suggestion] — "Shim smoke check" only half-applied.
daemonStatusProvider.test.ts now routes `BridgeOptions` and
`HttpAcpBridge` types through `./httpAcpBridge.js` shim too
(alongside `createHttpAcpBridge`), so the entire factory surface
the cli tests rely on flows through the F1 re-export shim.
N1 [Nit] — Asymmetric split-marker phrasing.
Both markers now describe the 4 moved tests by surface
(env real / preflight idle / preflight merged-live /
preflight extMethod-throws) rather than "1 of" + "3 more".
N2 [Nit] — testUtils "the suite" ambiguity.
makeChannel JSDoc now references `bridge.test.ts` explicitly
instead of "the suite" (which was unambiguous pre-split when
helpers + 10 createInMemoryChannel sites lived in the same file).
Verification: 291/291 acp-bridge tests pass; 4/4 cli daemon
integration tests pass; tsc clean on both packages (pre-existing
server.ts errors on baseline unchanged); eslint --max-warnings 0
clean on all 4 touched files.
* docs(cli): self-review round 2 — fix stale vitest.config.ts alias comment
Round 2 reviewer caught a 3-way contradiction in the round 1 docs:
- vitest.config.ts said: alias replaces the export, internal/* stays
unpublished (matches stderrLine convention).
- package.json: subpath export IS declared.
- testUtils.ts JSDoc: both channels intentionally retained,
testUtils ships in dist.
Round 1 explicitly chose to retain the export because TS `nodenext`
won't fall back to tsconfig `paths` once `exports` rejects a
subpath; the alias only serves to short-circuit *runtime* resolution
so cli reads src/ not dist/. Rewriting the vitest.config.ts comment
to reflect that dual-channel reality (and pointing readers at
testUtils.ts for the full rationale).
* fix(acp-bridge): #4445 round 3 fold-in — 4 of 7 reviewer threads adopted
PR #4445 review pass — 4 adopt + 3 decline (declines replied
inline; not folded here):
ADOPTED:
T1 [copilot daemonStatusProvider.test.ts:136 — bridge.shutdown
missing]: added `await bridge.shutdown()` to test 2 (preflight
idle). Three of four tests already shut down; symmetry +
future-proof if `createHttpAcpBridge` gains background work
even when no channel was spawned.
T5 [wenshao testUtils.ts:92 — makeBridge naming collision]: cli-
side helper renamed `makeBridge` -> `makeBridgeWithDaemonStatusProvider`
(4 call sites in daemonStatusProvider.test.ts), JSDoc updated to
reference the wenshao thread. testUtils.makeBridge stays as the
canonical name used by ~100 tests in bridge.test.ts. A future
contributor can no longer pick the wrong helper by accident.
T6 [wenshao testUtils.ts:32 — JSDoc mis-claims @internal tag matches
stderrLine.ts convention]: fixed wording. stderrLine.ts uses prose
only; @internal is an additional package-private signal, not a
convention match. Also restructured the npm-leak paragraph to
describe the new .npmignore-via-files-negation enforcement (T7).
T7 [wenshao package.json:70 — testUtils ships to npm]: switched
`files: ["dist"]` -> `files: ["dist", "!dist/internal/testUtils.*",
"!dist/**/*.test.*"]`. Wenshao's suggested `"test"` exports
condition wasn't viable: vitest sets `vitest` not `test`, and
gating on `vitest` would hide types from the cli's tsc compile.
The negation-pattern files-field excludes the built testUtils
from the publish surface while keeping the subpath export entry
that TypeScript `nodenext` needs to resolve types. Verified via
`npm pack --dry-run`: dist/internal/stderrLine.* still ships
(production internal helper); dist/internal/testUtils.* +
dist/**/*.test.* are excluded.
DECLINED (replied on PR threads, not folded here):
T2/T3 [copilot — `handles` array unused in tests 3/4]: bookkeeping
matches the pre-split bridge.test.ts verbatim; cleanup is scope
creep on this rename PR.
T4 [copilot — testUtils eager-imports createHttpAcpBridge,
cross-copy identity risk]: cli daemonStatusProvider.test.ts uses
its OWN local `makeBridgeWithDaemonStatusProvider` and never
imports testUtils.makeBridge — the cross-copy concern isn't
triggered. Premature abstraction on a test-only fixture.
Verification: 291/291 acp-bridge tests pass; 4/4 cli daemon tests
pass; tsc clean both packages; eslint --max-warnings 0 clean on
2 touched .ts files; `npm pack --dry-run` confirms publish-surface
exclusions.
* fix(core): F2 cleanup PR B — self-heal observability (W133-a + W134) (#4460)
* fix(core): F2 cleanup PR B — self-heal observability (W133-a + W134)
W93 declined as already satisfied by W1 fix in #4336 commit 6
(spawnEntry's catch already calls forceShutdown which runs the full
cleanup table — listener removal, timer clear, subscriber detach,
sweep+disconnect, onClosed eviction). Source-verified non-repro.
W133-a: McpClient.onerror now captures the error in a private
`lastTransportError` field (reset at each connect()); the W120
silent-drop block at mcp-pool-entry.ts:346 reads it via the new
`getLastTransportError()` getter and appends `: <error.message>` to
the lastError string on the emitted 'failed' event. Preserves the
literal "silent transport drop" prefix invariant for log-grep
backward compat — pre-fix marker stays a substring.
W134: sweepAndDisconnect now returns SweepResult instead of void —
{ pidSweepError?, disconnectError?, descendantsFound?,
descendantsSignaled? }. The silent-drop fire-and-forget caller chains
to inspect the result and emits a structured warn log when either
pid-sweep threw OR sigtermPids partially signaled (signaled < found)
— surfaces orphan-process pressure without inflating PR scope (no
new SSE event or SDK reducer state; deferred to W134-followup if
maintainers want metrics).
forceShutdown / doRestart sweep callers ignore the return value (JS
implicit-void at await sites preserves behavior).
4 new tests in mcp-transport-pool.test.ts covering W133-a happy path
+ fallback (no prior onerror) + W134 pidSweepError + W134
partial-signal failure modes. Module-mocks pid-descendants.js for
controllable sweep behavior, and debugLogger.js to observe warn
calls (production logger is session-gated and a no-op in tests).
Singleton-stub debugLogger mock so production module-load
`createDebugLogger('McpPool:Entry')` and the test's retrieval get
the same vi.fn instances.
Verification:
- tsc clean: packages/core, packages/cli (server.ts pre-existing
errors unchanged)
- F2 transport-pool: 32/32 pass (28 pre-existing + 4 new)
- mcp-client: 46/46 pass
- eslint --max-warnings 0 clean on 3 touched files
Part of #4175 #4336 follow-up bucket.
* fix(core): #4460 round 1 fold-in — 4 copilot doc/comment threads adopted
T1 [copilot mcp-pool-entry.ts:116 — stale line ref in SweepResult JSDoc]:
replaced `mcp-pool-entry.ts:383` with stable method-anchor reference
to the W120 silent-drop block inside `statusChangeListener`. Line
numbers drift on every edit; method names don't.
T2 [copilot mcp-pool-entry.ts:453 — `?? 0` ambiguous in warn payload]:
silent-drop warn log now prints `descendantsFound=unknown` and
`descendantsSignaled=unknown` when the values are undefined (only
reachable in the pidSweepError branch — sweep threw before
assignment). Operators triaging the warn can now distinguish
"sweep succeeded but found 0 descendants" from "sweep itself
threw, count is genuinely unmeasured". Locked in via a new
assertion in the W134 pidSweepError test.
T3 [copilot mcp-client.ts:116 — brittle line refs in lastTransportError
JSDoc]: replaced `mcp-pool-entry.ts:346` and `mcp-client.ts:130`
with stable method/block names (the `statusChangeListener` silent-
drop block; the `client.onerror` arrow inside connect()). Same
fix applied to the parallel comment in mcp-transport-pool.test.ts:730
for consistency.
T4 [copilot mcp-transport-pool.test.ts:797 — singleton-stub mock comment
contradictory]: rewrote the comment to unambiguously describe what
the mock DOES (factory body runs once; inner arrow returns the same
object on every call) instead of the prior hypothetical phrasing
("Returning a fresh object would have...") which read as a
description of current behavior at first glance.
All 4 are doc/comment fixes — zero behavior change apart from the
T2 string format ('unknown' instead of '0'). Verified:
- 32/32 mcp-transport-pool.test.ts pass
- tsc clean on packages/core
- eslint --max-warnings 0 clean on 3 touched files
* fix(core): #4460 round 2 fold-in — remove dead SweepResult.disconnectError field
T5 [wenshao mcp-pool-entry.ts:134 — `disconnectError` is dead data]:
glm-5.1 review caught that the field was populated when
`client.disconnect()` threw (line 844) but no consumer ever read
it — the silent-drop `.then()` handler gated only on
`pidSweepError` and partial-signal; `forceShutdown` and `doRestart`
ignore the return; no test asserted on it.
Removed the field from `SweepResult` and the assignment in the
disconnect catch. The pre-existing `debugLogger.error(`client.disconnect
failed for ...`)` inside `sweepAndDisconnect` already gives operators
the signal — adding it to the outer silent-drop warn would have been
duplicate noise. If a future consumer needs to gate logic on disconnect
failures, re-add the field + reader at that point.
Verification: 32/32 mcp-transport-pool.test.ts pass; tsc + eslint
clean on the touched file.
* feat(sdk/daemon-ui): unified completeness follow-up to #4328 (#4353)
* feat(sdk/daemon-ui): expand event coverage to 28+ daemon event types (PR-A)
Closes the "12+ daemon events fall through to debug" gap surfaced in the PR
the daemon currently emits (Stage 1 + Wave 3-4), so renderers stop having
to peek at `rawEvent.data` for known event categories.
Session-meta:
- session.metadata.changed (from session_metadata_updated)
- session.approval_mode.changed (from approval_mode_changed)
- session.available_commands (from available_commands_update; upgraded
from a status-text fallback to a typed event carrying the command list)
Workspace state (Wave 3-4):
- workspace.memory.changed
- workspace.agent.changed
- workspace.tool.toggled
- workspace.initialized
- workspace.mcp.budget_warning
- workspace.mcp.child_refused
- workspace.mcp.server_restarted
- workspace.mcp.server_restart_refused
Auth device-flow (Wave 4 OAuth, RFC 8628):
- auth.device_flow.started
- auth.device_flow.throttled
- auth.device_flow.authorized
- auth.device_flow.failed (carries DaemonAuthDeviceFlowSdkErrorKind)
- auth.device_flow.cancelled
- `DaemonUiErrorEvent.errorKind?: DaemonErrorKind` — closed-enum error
category propagated from daemon's typed-error taxonomy. Renderers can
branch on errorKind for "retry auth" vs "check file path" affordances
instead of regex-matching `text`.
- `DaemonUiToolUpdateEvent.provenance?: DaemonUiToolProvenance` +
`.serverId?` — closed enum ('builtin' | 'mcp' | 'subagent' | 'unknown').
Falls back to the `mcp__<server>__<tool>` naming heuristic when the
daemon doesn't stamp provenance explicitly. Unblocks UI namespace
dispatch without string-matching toolName.
Session-meta / workspace / auth events do NOT push transcript blocks.
They are intentional sidechannel observations: `lastEventId` advances
(monotonic invariant preserved), but the chat-stream transcript stays
focused on user/assistant/tool/shell/permission content. Renderers
consume them via selectors (introduced in follow-up PRs).
All new event types produce short structured lines in
`daemonUiEventToTerminalText` for tail-style debug consumers. Web/IDE
renderers should consume the typed events directly via subscription.
40/40 tests pass. New tests verify:
- All 16 new event types normalize correctly
- Malformed payloads fall back to debug without leaking raw data
(`secret` field never appears in fallback text)
- MCP tool provenance heuristic (`mcp__github__create_issue` →
provenance='mcp', serverId='github')
- errorKind propagation on session_died / stream_error
- Reducer is no-op on new event types; lastEventId still advances
This is PR-A of the unified-renderer-layer follow-up series:
- PR-A (this commit) — event coverage + closed-enum schema
- PR-B — server-side timestamps + ordering refactor
- PR-C — multimodal content + tool preview taxonomy
- PR-D — render contract (toMarkdown / toHtml / toPlainText) + adapter
conformance test framework
- PR-E — reducer state machine (subagent / progress / current tool /
cancellation propagation)

* feat(sdk/daemon-ui): server timestamps + event-id-based ordering (PR-B)
Closes the "时间定义不标准" gap surfaced in the PR #4328 review:
- Client-side `Date.now()` drifts across clients
- No daemon-authoritative timestamp propagated to UI
- Out-of-order replay events get fresher `state.now` than originals,
breaking `createdAt` ordering
- `DaemonUiEventBase.serverTimestamp?: number` — daemon-authoritative
wall-clock timestamp extracted from envelope.
- `DaemonTranscriptBlockBase.serverTimestamp?: number` + `clientReceivedAt: number`.
- `createdAt` preserved as `@deprecated` alias for `clientReceivedAt`
(backward compat for code written before this PR).
`extractServerTimestamp` looks at three candidate envelope locations:
1. `event.serverTimestamp` (preferred when daemon adds it)
2. `event._meta.serverTimestamp` (Anthropic-style metadata convention)
3. `event.data._meta.serverTimestamp` (sessionUpdate nested location)
The SDK is ready to consume serverTimestamp WHEN daemon emits it, without
requiring a coordinated SDK release. Undefined when daemon doesn't emit
(current state) — graceful degradation to client-clock ordering.
`selectTranscriptBlocksOrderedByEventId(state)` — returns blocks sorted by:
1. `eventId` (daemon-monotonic SSE cursor) — primary key
2. `serverTimestamp` (daemon wall clock) — fallback for synthetic frames
3. `clientReceivedAt` (local clock) — last resort
Use this when displaying long sessions where event id 5 may arrive AFTER
event id 7 (typical in SSE replay-after-reconnect).
`formatBlockTimestamp(block, opts)` — formats the most authoritative
timestamp on a block using `Intl.DateTimeFormat`. Prefers
`serverTimestamp` over `clientReceivedAt` for cross-client consistency.
Accepts locale / timeZone / dateStyle / timeStyle.
Daemon needs to stamp `_meta.serverTimestamp` on every SSE envelope. This
SDK PR is ready to consume it the moment the daemon ships the field; no
coordination needed.
- serverTimestamp extraction from all three envelope locations
- Defaults undefined when envelope has none
- `selectTranscriptBlocksOrderedByEventId` sorts mixed-arrival events by
eventId (replay scenario)
- `formatBlockTimestamp` prefers serverTimestamp; returns localized string

PR-E in one branch).

* feat(sdk/daemon-ui): reducer state machine — currentTool / approvalMode / cancellation propagation (PR-E)
Closes the "reducer state machine 设计缺漏" gap surfaced in the PR #4328 review:
- No `currentTool` — UI scans `blocks[]` to find the running tool
- No mirrored approval mode — UI walks events to badge "plan"/"yolo"
- Cancellation does not propagate — in-flight tool blocks stuck at
'in_progress' forever when the parent prompt is cancelled
## State additions (sidechannel, no transcript blocks)
`DaemonTranscriptSidechannelState`:
- `currentToolCallId?: string` — toolCallId of the in-flight tool
- `approvalMode?: string` — mirrored from session.approval_mode.changed
- `toolProgress: Record<string, { ratio?, step? }>` — per-tool progress
shape (daemon-side emission of `tool.progress` events pending)
## Reducer behavior
### `tool.update` events
`IN_FLIGHT_TOOL_STATUSES` = { pending, confirming, running, in_progress }
`TERMINAL_TOOL_STATUSES` = { completed, success, failed, error, canceled, cancelled }
- Tool enters in-flight: set `currentToolCallId = event.toolCallId`
- Tool enters terminal: clear `currentToolCallId` if it matches
- Unknown status (forward-compat): leave pointer untouched
This avoids the failure mode where a future daemon-emitted status like
`'paused'` would silently mark unknown states as either in-flight or
terminal incorrectly.
### `session.approval_mode.changed`
Mirror `event.next` onto `state.approvalMode`. Renderers can render a
mode badge ("plan" / "default" / "auto-edit" / "yolo") with a single
selector call, no event-stream walking.
### `assistant.done` with `reason === 'cancelled'`
`propagateCancellationToInFlightTools` walks every tool block whose
status is still in-flight and force-sets it to 'cancelled'. The daemon
does not guarantee terminal `tool_call_update` for every in-flight tool
when the parent prompt is cancelled, so this propagation prevents UI
spinners from spinning forever.
`currentToolCallId` is also cleared in the same call.
Non-cancellation `assistant.done` (e.g., `reason: 'end_turn'`) does NOT
propagate — in-flight tools remain in-flight until the daemon emits
their terminal update naturally.
## Selectors
- `selectCurrentTool(state)` — returns the running tool block, or undefined
- `selectApprovalMode(state)` — returns the mirrored approval mode
- `selectToolProgress(state, toolCallId)` — per-tool progress query
All exported from `@qwen-code/sdk/daemon`.
## Scope deliberately deferred
Subagent nesting (`parentBlockId` / `delegationId` / `DaemonSubagentTranscriptBlock`)
is NOT in this PR. The shape needs design discussion (how to project nested
events; whether to bake delegation tracking into transcript or sidechannel).
PR-D / PR-F follow-up.
## Test coverage (51/51 pass)
- currentToolCallId set on enter, cleared on terminal
- approvalMode mirrors changes
- Cancellation marks in-flight tools 'cancelled', leaves completed alone
- Unknown status does NOT clear currentToolCallId (forward-compat)
- Non-cancellation `assistant.done` does NOT propagate
## Roadmap
PR-E of the unified follow-up to PR #4328 (PR-A + PR-B + PR-E in this

* feat(sdk/daemon-ui): tool preview taxonomy + multimodal content extraction (PR-C)
Closes two related gaps surfaced in the PR #4328 review:
- `DaemonToolPreview` had only 4 kinds — UI fell back to `key_value` /
`generic` for tools that deserved structured display
- `getTextContent` silently dropped non-text content (image / audio /
resource), so multimodal conversations vanished from the UI
`DaemonToolPreview` extends from 4 to 8 variants:
- `file_diff` — `{ path, oldText?, newText?, patch? }` — file edit tools
(Anthropic-style `oldText/newText`, aider-style `patch`, write-style
`newText` alone)
- `file_read` — `{ path, range?: [start, end] }` — file read tools, with
range extracted from `lineRange` tuple OR `offset/limit` pair
- `web_fetch` — `{ url, method? }` — HTTP fetch tools (requires URL
with scheme to avoid false positives on relative paths)
- `mcp_invocation` — `{ serverId, toolName, argsSummary? }` — MCP server
tool calls, identified via `mcp__<server>__<tool>` naming convention
(same heuristic as PR-A `DaemonUiToolUpdateEvent.provenance`)
Detector order matters — MCP wins first (most specific), then file_diff,
file_read, web_fetch, then the existing command / key_value fallbacks.
New helper `extractContentPart(value): DaemonUiContentPart | undefined`
returns a discriminated union:
```ts
type DaemonUiContentPart =
| { kind: 'text'; text: string }
| { kind: 'image'; mediaType: string; source: { url?, data? } }
| { kind: 'audio'; mediaType: string; source: { url?, data? } }
| { kind: 'resource'; uri: string; mediaType?, description? };
```
The existing `getTextContent` is preserved for backward compat. Renderers
that need to surface non-text content (web UI thumbnails, IDE attachment
chips) now have a typed shape to consume.
- Wiring `extractContentPart` into the normalizer / reducer so text
blocks accumulate `parts: DaemonUiContentPart[]` alongside `text`
(additive shape change requires render contract coordination — PR-D).
- 5 additional tool preview kinds (image_generation / code_block /
tabular / subagent_delegation / search) — useful but not urgent;
current 8 kinds cover the typical agent flows.
- file_diff detection from Anthropic / aider / write shapes
- file_read with lineRange tuple AND offset+limit pair
- web_fetch with method, REJECTS relative paths (no scheme)
- mcp_invocation with serverId + toolName extraction
- Detector priority: MCP wins over file_diff on conflicting shapes
- extractContentPart for text / image (url) / audio (data) / resource
- Unknown content type returns undefined (skip rather than synthesize)
- Image without source returns undefined (defensive)

* feat(sdk/daemon-ui): render contract — markdown / HTML / plain text helpers (PR-D)
Closes the "render 契约只覆盖 terminal" gap surfaced in the PR #4328 review:
> PR ships `daemonUiEventToTerminalText` for terminal. Web/IDE/channel
> adapters each roll their own projection. No shared contract → adapter
> divergence is inevitable.
## New helpers
```ts
daemonBlockToMarkdown(block, opts?): string // GFM-compatible
daemonBlockToHtml(block, opts?): string // conservatively escaped HTML
daemonBlockToPlainText(block, opts?): string // for copy-paste / logs
daemonToolPreviewToMarkdown(preview, opts?): string
```
All three respect the same `kind` discrimination so adapters can switch
between them without touching call sites.
## Per-kind projection
For each `DaemonTranscriptBlock['kind']`:
- `user` / `assistant` / `thought` — plain text with role labels
- `tool` — header with toolName + structured preview + status badge
- `shell` — fenced code block, stream-discriminated (stdout vs stderr)
- `permission` — title + options list + resolved/pending indicator
- `status` / `debug` / `error` — semantic class / role (error → role=alert)
For each `DaemonToolPreview['kind']`:
- `ask_user_question` — question + options as bullet list
- `command` — fenced bash with optional cwd comment
- `file_diff` — unified diff in fenced code block (oldText/newText OR patch)
- `file_read` — `path (lines N-M)` line
- `web_fetch` — `METHOD url` line
- `mcp_invocation` — `serverId::toolName` with args summary
- `key_value` — bullet list
- `generic` — emphasized summary
## Security
- Default HTML sanitizer escapes `<`, `>`, `&`, `"`, `'` and FIRST strips
ANSI/control sequences via `sanitizeTerminalText` (defense against
agent-emitted escape codes in HTML output).
- Custom sanitizer hook for consumers wanting markdown→HTML pipelines
(markdown-it + DOMPurify, etc.).
- `sanitizeUrls` option strips token-like query params (`token=`, `key=`,
`x-amz-`, etc.) from URLs in `web_fetch` previews.
- `maxFieldLength` truncation defaults 8192, prevents pathological
rendering on huge content.
## Adapter conformance (out of scope for this commit)
The conformance test framework (fixture corpus + `runAdapterConformanceSuite`)
mentioned in PR-D scope is deferred to a follow-up. The render helpers
here are the precondition — once stable, the conformance framework can
use them as the reference projection.
## Test coverage (77/77 pass)
- All 9 block kinds render in markdown (verified for user/assistant/tool/
shell/permission/error specifically)
- file_diff renders as unified diff with old/new lines
- mcp_invocation renders as `server::tool` format
- HTML escapes XSS (`<script>` → `<script>`)
- HTML strips terminal escape sequences before escaping
- Error blocks emit `role="alert"` for screen readers
- plain text drops markdown delimiters
- maxFieldLength truncates with ellipsis
- sanitizeUrls strips token query params
- Custom sanitizer hook works
## Roadmap
PR-D of the unified follow-up to PR #4328 — completes the 5-PR series
(A: event coverage, B: time schema, E: state machine, C: tool preview +
content extraction, D: render contract).

* feat(sdk/daemon-ui): 5 additional tool preview kinds — taxonomy complete (PR-F)
Closes the "5 additional preview kinds" item in PR #4353's TODO §A
(SDK-only work).
## New preview kinds (8 → 13)
- `code_block` — `{ language?, code, origin? }` — REPL / formatter /
generator output, fenced as `\`\`\`<language>` in markdown
- `search` — `{ query, resultCount?, top? }` — grep / ripgrep / find /
glob results with up to 5 top hits
- `tabular` — `{ columns, rows, totalRows? }` — structured table output
(50-row cap with `totalRows` truncation indicator); supports both
`columns: string[] + rows: unknown[][]` explicit shape and legacy
`data: Array<Record<>>` shape (auto-infers columns from first row)
- `image_generation` — `{ prompt, thumbnailUrl?, model? }` — dall-e /
diffusion / imagen / flux / sora style tools
- `subagent_delegation` — `{ agentName, task, parentDelegationId? }` —
Anthropic-style Task tool and similar sub-agent dispatchers
## Detector priority
Order matters — most specific wins. New detectors slot in between
`mcp_invocation` and `file_diff`:
```
mcp_invocation > subagent_delegation > search > image_generation
> file_diff > file_read > web_fetch > code_block > tabular
> command > key_value > generic
```
Rationale: subagent / search / image generation are most discriminable
(distinct toolName patterns); file ops next; code_block / tabular last
because their shapes (`code:`, `columns:`) can appear in other tools.
## Render projections
Both `daemonToolPreviewToMarkdown` and the plain-text rendering paths
extended with cases for all 5 new kinds:
- code_block: fenced markdown code block with language tag
- search: bold header + GFM bullet list of top results
- tabular: GFM pipe table with header / separator / body / truncation hint
- image_generation: bold header + blockquoted prompt + embedded markdown
image (URL sanitization respected via `sanitizeUrls` opt)
- subagent_delegation: bold delegate-arrow header + blockquoted task +
optional parent delegation reference
## Test coverage (91/91 pass, +14 new)
- Each detector with positive case
- Detector priority verified: subagent_delegation wins over file_diff
when toolName='Task' has both subagent + file-edit fields
- Tabular row cap (50) + totalRows stamping for truncated data
- Legacy data: Array<Record<>> auto-column inference
- Each render projection with structural assertions (markdown table
format, image embed, bullet lists)
## Roadmap
PR-F of the unified follow-up to PR #4328. Brings the preview taxonomy
to 13 kinds covering: file ops (3), web (1), code/data (2), media (1),
agent control (2 — ask_user_question + subagent_delegation), MCP (1),
search (1), generic fallbacks (2).

* feat(sdk/daemon-ui): adapter conformance framework + fixture corpus (PR-G)
Closes the "Adapter conformance test framework" item in PR #4353's TODO §A.
Lets any daemon-ui adapter (TUI / web / IDE / channel / mobile) validate
that it projects a fixed corpus of daemon SSE event streams to the same
semantic shape — catches projection drift before it reaches users.
## API surface
```ts
interface DaemonUiAdapterUnderTest {
reduce(events: readonly DaemonUiEvent[]): unknown;
renderToText(state: unknown): string;
}
interface DaemonUiConformanceFixture {
name: string;
description: string;
envelopes: DaemonEvent[]; // raw daemon envelopes
expectedContains: string[]; // phrases the rendered text MUST contain
expectedAbsent?: string[]; // phrases that MUST NOT appear
normalizeOptions?: { ... }; // forward-compat normalize opts
}
runAdapterConformanceSuite(adapter, opts?): ConformanceSuiteResult
DAEMON_UI_CONFORMANCE_FIXTURES: ReadonlyArray<DaemonUiConformanceFixture>
```
## Design
**Format-agnostic assertion**: adapters can render to ANSI / HTML /
markdown / JSX — the framework only inspects plain text via
`renderToText`. Catches semantic divergence (missing user message,
wrong tool status, leaked secret) without forcing identical formatting.
**Embedded fixture corpus** (no fs reads — works in browser bundle):
- `simple-chat` — user/assistant streaming flow
- `tool-call-lifecycle` — running → completed transition
- `file-edit-diff` — file_diff preview surfacing
- `mcp-invocation` — MCP serverId/toolName extraction via heuristic
- `permission-lifecycle` — request + resolved with outcome
- `mcp-budget-warning` — Wave 3 event (adapter must observe but rendering
is its choice)
- `cancellation-propagates` — tool block status flows
- `malformed-payload-redaction` — uses `includeRawEvent: true` to verify
even a debug-mode adapter doesn't leak `token: secret-do-not-leak`
- `auth-device-flow-success` — Wave 4 OAuth events
- `available-commands-typed-event` — PR-A upgrade from status text
Per-fixture `expectedContains` and `expectedAbsent` describe the
content contract independently of format.
## Suite result
```ts
{
passed: number,
failed: ConformanceFailure[], // each carries missing + leaked + excerpt
total: number,
}
```
**Does not throw** — caller asserts on `result.failed` so adapter test
suites can produce per-fixture diagnostics rather than a single opaque
exception.
## Filter options
`only` / `skip` allow targeted runs during adapter development:
```ts
runAdapterConformanceSuite(myAdapter, { only: ['simple-chat'] });
runAdapterConformanceSuite(myAdapter, { skip: ['cancellation-propagates'] });
```
## Test coverage (97/97 pass, +6 new)
- SDK reference adapter (reducer + markdown render) passes all fixtures
- SDK reference adapter (reducer + plainText render) also passes
- Buggy adapter (empty string output) fails every fixture with non-empty
`expectedContains`
- Buggy adapter (raw event dump via JSON.stringify) caught by redaction
fixture's `expectedAbsent`
- `only` filter narrows to a single fixture
- `skip` filter excludes named fixtures from the corpus
## Usage from adapter authors
```ts
// In your adapter's test file
import { runAdapterConformanceSuite } from '@qwen-code/sdk/daemon';
import { reduceForTui, renderTuiState } from './my-tui-adapter';
it('TUI adapter conforms to daemon UI corpus', () => {
const result = runAdapterConformanceSuite({
reduce: reduceForTui,
renderToText: renderTuiState,
});
expect(result.failed).toEqual([]);
});
```
## Roadmap
PR-G of the unified follow-up to PR #4328. The corpus is intentionally
small (10 fixtures) but extensible — adapter authors can submit new
fixtures via additions to `DAEMON_UI_CONFORMANCE_FIXTURES` to lock in
regression coverage for edge cases their adapter encountered.

* feat(webui+sdk/daemon-ui): wire transcriptAdapter to SDK render contract (PR-H)
Closes the "WebUI transcriptAdapter migration" item in PR #4353's TODO §A.
Validates the PR-D render contract end-to-end on the real WebUI consumer.
`daemonTranscriptToUnifiedMessages(blocks, options?)` gains a new options
parameter:
```ts
interface DaemonTranscriptAdapterOptions {
useMarkdown?: boolean; // default: false
enrichToolDetailsWithPreview?: boolean; // default: false
}
```
Defaults preserve legacy behavior — existing callers see no change.
For `user` / `assistant` / `thought` blocks, content is projected via
SDK's `daemonBlockToMarkdown` instead of raw sanitized text. The WebUI's
markdown renderer (markdown-it) then gets:
- `**You**\n\n<content>` for user blocks (bold "You" label)
- Raw text for assistant blocks (markdown formatting in agent output
passes through cleanly)
- `> *thought:* <text>` blockquote for thought blocks
For `tool` blocks, `rawOutput` is replaced with `daemonToolPreviewToMarkdown(block.preview)`.
This lets WebUI surfaces without per-preview-kind React components still
display:
- `file_diff` as a fenced unified diff
- `mcp_invocation` as `server::tool` with args summary
- `tabular` as GFM pipe table
- `search` as bullet list with match count
- `image_generation` as embedded markdown image
- `subagent_delegation` as delegate arrow + task quote
Renderers with per-kind components should leave this opt-out.
`packages/sdk-typescript/src/daemon/index.ts` was missing exports for
PR-D / PR-F / PR-G / PR-B / PR-E surface — WebUI's `@qwen-code/sdk/daemon`
import path uses the daemon root, not the ui/ sub-index. Added 15+
re-exports so consumers don't need to use the longer
`@qwen-code/sdk/daemon/ui/index.js` path.
Now exported from `@qwen-code/sdk/daemon` root:
- `daemonBlockToMarkdown` / `daemonBlockToHtml` / `daemonBlockToPlainText`
- `daemonToolPreviewToMarkdown`
- `extractContentPart` + `DaemonUiContentPart` type
- `formatBlockTimestamp` + `selectTranscriptBlocksOrderedByEventId`
- `selectCurrentTool` / `selectApprovalMode` / `selectToolProgress`

`webui/src/daemon/transcriptAdapter.test.ts` mock blocks updated to include
`clientReceivedAt` (required field added in PR-B). Mechanical change —
every `createdAt: N` test fixture gets a matching `clientReceivedAt: N`.
- WebUI `npm run typecheck` — clean
- SDK `npm run typecheck` — clean
- SDK `vitest run test/unit/daemonUi.test.ts` — 97/97 pass
- WebUI transcriptAdapter test fixtures typecheck against updated

* fix(daemon-ui): address review feedback
* fix(daemon-ui): address review hardening feedback
* fix(daemon-ui): handle resync-required events
* feat(sdk/daemon-ui): consume daemon-side subagent nesting context (PR-K)
Closes the SDK-side gap for §B1 in PR #4353's TODO list. PR-E originally
deferred subagent nesting because daemon-side parent-context wasn't yet
stamped on tool_call events. After the rebase onto current
daemon_mode_b_main, source verification confirms the daemon now emits
`tool_call._meta.parentToolCallId` + `tool_call._meta.subagentType` via
`SubAgentTracker.getSubagentMeta()` (core), so the SDK side is unblocked.
## Schema additions (additive, forward-compat-safe)
`DaemonUiToolUpdateEvent`:
- parentToolCallId?: string — toolCallId of the parent Task / delegation
- subagentType?: string — sub-agent type label (e.g. 'code-reviewer')
`DaemonToolTranscriptBlock`:
- parentToolCallId?: string — mirror of event field
- subagentType?: string — mirror of event field
- parentBlockId?: string — pre-resolved by reducer when parent already
in state, so renderers don't re-correlate
## Normalizer wiring
`normalizeToolUpdate` checks both top-level and `_meta` for parentToolCallId
+ subagentType (fallback chain mirrors how provenance/serverId are read).
Top-level tool calls without sub-agent context omit the fields cleanly.
## Reducer behavior
- New tool block: resolves `parentBlockId` from `toolBlockByCallId` at
create time. Out-of-order arrival (child before parent) leaves
`parentBlockId` undefined — selectors fall back to `parentToolCallId`
lookup.
- Existing tool block update: adopts parent context if not yet
correlated, never overwrites established correlation (handles the
flow where SubAgentTracker activates after the initial tool_call).
## New public selectors
- selectSubagentChildBlocks(state, parentToolCallId): returns the
array of tool blocks invoked inside a given parent delegation
- isSubagentChildBlock(block): type guard for "this tool block came
from a sub-agent"
Both exported from @qwen-code/sdk/daemon root + ui/index.
## Forward-compat properties
- Top-level tool calls (no sub-agent) work identically as before
- Trimmed parent blocks: child fallback to undefined parentBlockId
- Daemon emits both fields together; SDK reads independently to tolerate
partial future stamping
## Test coverage (129/129 pass, +5 new tests)
- Extract parentToolCallId + subagentType from `_meta`
- Top-level tool calls have undefined parent fields (forward-compat)
- Reducer correlates parentBlockId at create time
- Reducer adopts parent context on later update (out-of-order arrival)
- isSubagentChildBlock discriminator
## Roadmap
PR-K of the unified follow-up to PR #4353. Closes §B1 (subagent nesting)
in the TODO declaration; daemon-side already shipped on
`daemon_mode_b_main` via SubAgentTracker (core).
Remaining TODO §B / §D items still depend on further daemon/Core work:
- §B2 `tool.progress` event type (daemon emit pending)
- §D MessageEmitter multimodal echo + HistoryReplayer inlineData/fileData
(core change pending)

* fix(daemon-ui): PR-K self-review hardening — back-fill / trim / self-ref / docs
Multi-round self-review of PR-K (d8375fe46) surfaced two real bugs, a
few defensive gaps, and missing docs/fixture coverage. All addressed
in one commit.
## Bugs fixed
### Bug 1 — `parentBlockId` never back-filled for out-of-order arrival
Original PR-K resolved `parentBlockId` only at child create time, which
broke this flow:
1. Child arrives WITH parent stamp → block created with
`parentToolCallId` set, `parentBlockId` undefined (parent not in
state yet)
2. Parent arrives later → block created, `toolBlockByCallId` indexed
3. Subsequent child updates: existing-block branch only ran the
back-fill inside `!existing.parentToolCallId`, which is false (we
already adopted the stamp in step 1). `parentBlockId` stayed
undefined forever.
Fix: separate the two correlations.
- existing-block update: independently back-fill `parentBlockId`
whenever `parentToolCallId` is set and `parentBlockId` is missing
- new-block create: scan existing children whose `parentToolCallId`
matches the new block's `toolCallId` and back-fill their
`parentBlockId`. Cheap O(n) over current blocks.
### Bug 2 — dangling `parentBlockId` after trim
`trimTranscriptState` reset `toolBlockByCallId[id]` to the trimmed
sentinel for evicted blocks but did NOT walk surviving children to
null their `parentBlockId` references. Renderers walking
`blockIndexById.get(parentBlockId)` would get undefined, with no
"why" signal.
Fix: post-trim, walk remaining tool blocks; if `parentBlockId`
references an id not in `keptIds`, null it. `parentToolCallId` stays
(survives trimming so selector-keyed queries still work).
## Defensive hardening
- **Self-reference guard** (normalizer): drop
`parentToolCallId === toolCallId` before it reaches the reducer.
Daemon should never emit this, but defending costs nothing.
- **Selector docstring**: clarify `selectSubagentChildBlocks` returns
**direct** children only; document cycle / depth-cap responsibility
for renderers walking up the chain.
- **Cosmetic**: remove redundant `as DaemonToolTranscriptBlock` cast
in `isSubagentChildBlock` (TypeScript already narrows after
`block.kind === 'tool'` on the discriminated union).
- **Alphabetical**: move `isSubagentChildBlock` re-export to correct
position in both `daemon/index.ts` and `daemon/ui/index.ts`.
## Docs + conformance gaps closed
- `README.md` — new "Sub-agent nesting (PR-K)" section with full
reducer behavior, out-of-order handling note, recursive walk example,
cycle-defense note.
- `MIGRATION.md` — new step 8a with before/after for nested rendering.
- `conformance.ts` — new `subagent-nesting` fixture covering parent +
nested child via `tool_call._meta`. Markdown-safe phrases chosen
(markdown escapes `-` so titles cannot be substring-matched as-is).
## Test coverage (+5 tests, 134/134 pass)
- Self-reference dropped in normalizer
- Back-fill on out-of-order parent arrival (child first, parent after)
- Back-fill on later child update when parent now exists
- Dangling `parentBlockId` nulled after parent trimmed
- New `subagent-nesting` conformance fixture passes SDK reference adapter
## Side-effect verification
Verified no regressions:
- Cancellation propagation still cancels parent + children together
(iterates `toolBlockByCallId`, which includes both)
- Render contract unchanged (`daemonBlockToMarkdown` etc. project per
block, no nested awareness required)
- No serializer to update
- `selectTranscriptBlocksOrderedByEventId` unaffected (parent-agnostic)

* fix(daemon-ui): permission block trim contract — wenshao review
Addresses both items from wenshao's review on PR #4353:
## Critical — resolvePermissionBlock missing TRIMMED guard
The sibling `upsertPermissionBlock` (transcript.ts:544) correctly returns
early when `existingId === TRIMMED_PERMISSION_BLOCK_ID`, but
`resolvePermissionBlock` (transcript.ts:581) had no such guard. When
`maxBlocks` trimming evicted a pending permission request, a subsequent
`permission.resolved` event would:
1. Fail the `getWritableBlockById` lookup (sentinel is not a real block id)
2. Fall through and create a brand-new orphan resolution block
This wasted a block slot, accelerated further trimming, and silently
broke the trimmed-block contract that the request-side guard establishes.
Fix: mirror the request-side guard. Read the index entry up front,
return early on the sentinel.
## Suggestion — permissionBlockByRequestId grows unboundedly
`trimTranscriptState` writes `TRIMMED_PERMISSION_BLOCK_ID` for evicted
permission requests but never deletes those entries. Unlike the tool
side (which calls `pruneTrimmedToolIndexes` post-trim), the permission
index grew without bound in long sessions.
Fix: add `pruneTrimmedPermissionIndexes` analogous to the tool-side
helper. Caps the sentinel set at `maxBlocks` entries; older entries are
deleted (any later resolution event still drops cleanly via the new
Critical guard).
## Tests
- Updated existing `keeps orphan permission resolutions visible after
request trimming` test to encode the corrected contract (drops silently
instead of creating an orphan). Test rename: "drops resolution for
trimmed permission requests (wenshao Critical)".
- New `Suggestion: pruneTrimmedPermissionIndexes caps the trimmed
sentinel set` test verifies the cap.
Total: 136/136 tests pass, SDK + WebUI typecheck green.
## Side-effect verification
- `upsertPermissionBlock` already had the equivalent guard — no
asymmetry remains.
- `pruneTrimmedPermissionIndexes` only touches entries holding the
sentinel; live permission blocks are unaffected.
- Selectors over `state.blocks` (e.g. `selectPendingPermissionBlocks`)
iterate the block array, not the index — unaffected by cap.

* fix(daemon-ui): address wenshao + doudouOUC inline reviews (2026-05-23)
Addresses the 13 inline review comments from wenshao (6) and doudouOUC
(7, one overlap) on the 2026-05-23 review round.
## Critical / Important
### sanitizeUrls not threaded through HTML preview path (doudouOUC)
`daemonBlockToHtml` for tool blocks called `daemonToolPreviewToPlainText`
which didn't accept `opts` — when callers set `sanitizeUrls: true`, the
markdown path stripped auth tokens but the HTML path leaked them into
the DOM. Now: helper accepts opts, threads through `web_fetch.url` and
`image_generation.thumbnailUrl`.
### enrichToolDetailsWithPreview overwrote rawOutput (doudouOUC)
The webui adapter replaced structured `rawOutput` with a markdown
summary string when `enrichDetails: true`. Downstream `ToolCallData`
consumers may branch on the shape (object vs string) and break. Plus
the actual tool output was silently dropped.
Fix: keep `rawOutput` verbatim, surface markdown via a new optional
`previewMarkdown` field added to `ToolCallData`.
### transcriptBlockToTerminalText zero test coverage (wenshao)
Added 12 tests covering each `switch` branch (user / assistant / thought
/ tool / shell stdout+stderr / permission unresolved+resolved / status /
debug / error) plus the unknown-kind degradation path. Verified
`assertNever` returns a graceful error line (does NOT throw) — wenshao's
reviewer was slightly wrong on the throw claim but coverage gap was
real.
### selectTranscriptBlocksOrderedByEventId no memoization (wenshao)
Selector was called from React `useSyncExternalStore` and re-sorted on
every dispatch — including sidechannel-only events that don't touch
blocks. Added WeakMap cache keyed on `state.blocks` reference; the
reducer preserves the same array reference for non-block-mutating
events, so the cache hits across renders.
### selectSubagentChildBlocks O(n) per call (wenshao)
Naive `state.blocks.filter()` was O(n) per call; rendering a tree with
m parents made it O(n*m). Built a memoized reverse index keyed on
`state.blocks` reference (WeakMap of parentToolCallId →
DaemonToolTranscriptBlock[]). Each lookup now O(1) after first call.
### Test file TS errors at root tsc (wenshao)
Fixed multiple TS errors in `daemonUi.test.ts` flagged by root
`tsc --noEmit`:
- Added `DaemonTranscriptState` + `DaemonUiEvent` imports
- `block.content` access via `as Array<Record<string, unknown>>` cast
- `delete` on globalThis property via narrower interface cast
- `debug?.text` via `DaemonUiEvent & { text: string }` narrowing (Extract on
union with `'status' | 'debug'` literal would resolve to never)
- 6 occurrences of index-signature access via bracket notation
- `raw: null` added to 3 `DaemonUiPermissionOption` literals (required field)
- Explicit type annotations on conformance-suite `renderToText` params
Note: `webui/src/daemon/transcriptAdapter.test.ts` shows residual
"clientReceivedAt does not exist" errors at root tsc, but this is
environmental — the resolution trace shows `@qwen-code/sdk/daemon`
crossing into a sibling worktree's stale dist via shared workspace
node_modules. In a single-worktree CI checkout this resolves cleanly.
## Suggestions (cleanups)
### Hoist asDaemonErrorKind double-eval (doudouOUC)
`session_died` + `stream_error` cases each computed `asDaemonErrorKind`
twice in the conditional spread (predicate + value). Hoisted to const,
no functional change.
### renderToolHeader bypassed opts (doudouOUC)
Forwarded `opts` so `maxFieldLength` is honored for tool title /
toolName / toolKind.
### isSensitiveKey duplicates (doudouOUC)
Removed duplicate `endsWith('accesskey')` / `endsWith('secretkey')`
checks and the redundant exact-match `privatekey` (already covered by
`endsWith`).
### propagateCancellationToInFlightTools iterated trimmed (wenshao)
Filter `TRIMMED_TOOL_BLOCK_ID` sentinels up front. Avoids redundant
index dereferences in long sessions with many historical tools.
### toolProgress shallow clone (doudouOUC + wenshao)
`cloneTranscriptState` outer `...state` spread shared inner
`{ ratio?, step? }` references between snapshots. Once `tool.progress`
event handlers start mutating in place, the prior snapshot would leak.
Deep-clone the inner records now (cost bounded by in-flight tools,
small).
### isDeviceFlowErrorKind closed set (wenshao + doudouOUC)
Both reviewers suggested strict validation. We INTENTIONALLY kept
lenient pass-through — the public type
`DaemonAuthDeviceFlowSdkErrorKind` explicitly includes `(string & {})`
as a forward-compat escape hatch (existing test `keeps future
auth_device_flow_failed errorKind values observable` enforces this).
Now expose `KNOWN_DEVICE_FLOW_ERROR_KINDS` as documentation and
explain the design in the JSDoc.

…4721) (QwenLM#5094) * feat(core): Workflow P4a — extractAndStripMeta + meta on RunOutcome (QwenLM#4721) First half of P4 (per the refined QwenLM#4721 plan). Extracts the script's `export const meta = {...}` declaration into a typed object so the workflow tool's display payload, and the future /workflows command + phase-tree UI, can read it without re-parsing the script source. The other half of P4 (slash command + KIND_NAMES extension + phase-tree UI + WorkflowTaskRegistry) is queued as a follow-up PR. Architecture: reuse the P1 brace-walker (zero-dep, no parser deps) to locate the meta object literal's source range, then evaluate the literal inside a fresh `vm.createContext(Object.create(null))` — null-prototyped globalThis, no host bridge (no `args` / `process` / `require` / workflow- sandbox globals). The vm realm still exposes its OWN intrinsics (`Object` / `Math` / `Date` / `JSON`), which is fine: meta extraction is one-shot at tool invocation, not replayed on resume. validateMeta walks the eval result field-by-field and copies into a fresh host-realm plain object — no JSON round-trip needed because every contract field is a primitive. User-visible additions: - `extractAndStripMeta(source)` exported from workflow-sandbox.ts - `WorkflowMeta` interface (`{ name, description, whenToUse?, phases?: Array<{title, detail?, model?}> }`) — verbatim shape from upstream Claude Code 2.1.168 - `WorkflowSandbox.getMeta()` accessor alongside `getPhases()` / `getLogs()` - `WorkflowRunOutcome.meta: WorkflowMeta | null` (non-breaking add) - `WorkflowExecutionError.meta: WorkflowMeta | null` so the failure display shows the workflow's name / description / phases even when the script body throws - `WorkflowTool.execute` adds `meta` to the returnDisplay payload when present (omitted when the script had no meta) Error messages verbatim from upstream where applicable: - `meta.name must be a non-empty string` - `meta.description must be a non-empty string` Refactor: P1's `stripExportMeta` is preserved as a thin wrapper around a new `findMetaBlockBounds` helper that both old and new functions share. All 86 existing sandbox tests pass unchanged (no behavior regression in the strip path). Tests: - 11 new `extractAndStripMeta` unit tests covering happy path, optional fields, missing-required validation, malformed shape, vm-eval failure, null-prototype globalThis (no `args` / `process` / `require`), and unbalanced braces - 3 new `createWorkflowSandbox.getMeta()` integration tests - 3 new `WorkflowOrchestrator` outcome.meta tests (null path, parsed path, meta-survives-body-throw on the error path) - 3 new `WorkflowTool` display payload tests (meta in payload, omitted when absent, present on failure path) Suite: 207/207 workflow + adjacent regression green; typecheck + lint clean on packages/core. (Pre-existing acp test type errors in packages/cli are unrelated; CI will confirm.) Related QwenLM#4721 (parent design — multi-phase, not closed by this PR) Related QwenLM#4732 (P1) QwenLM#4947 (P2) QwenLM#5034 (P3) — all merged P4b follow-up: /workflows command + TaskKind workflow union + BackgroundTasksPill KIND_NAMES + phase-tree UI + WorkflowTaskRegistry * test(core): close P4a adversarial-review gaps + add real-LLM E2E (QwenLM#4721) After PR QwenLM#5094 opened without an E2E run, ran a 3-lens adversarial review (correctness / security / completeness) of the meta-extraction assertion strength against extractAndStripMeta and the meta-on-outcome threading path. All 3 reviewers refuted the claim that the existing assertions catch realistic regressions. Triage: - 18 of 24 findings already covered by workflow-sandbox.test.ts (string-with-brace, comments-inside-meta, phases[].model, missing-description error text, args/process/require unreachability, Promise/Math.constructor escape, etc.) - 4 findings (regex literal / template literal / `/m` flag / spread) are host-side parse-path branches the brace walker handles structurally but without explicit negative tests - 2 truly novel gaps closed here: 1. HIGH × 3 lenses: a regression in validateMeta that returns the vm-realm `raw` value directly (skipping the host-realm copy at workflow-sandbox.ts:283-294) would re-open T1/T8/T14 realm escape via outcome.meta.constructor.constructor('return process')(). Vitest toEqual is structural and does NOT check prototype identity, so every prior assertion in the suite would still pass. Add returned-meta + phases array + phase entries prototype- identity check in workflow-sandbox.test.ts; mirror end-to-end in the live test's scenario A. 2. MEDIUM: meta-shaped result collision — if a script returns `{ name, description, phases }`, the safeStringifyDisplayPayload spread must keep `meta` and `result` distinct at the top level. Add a workflow.test.ts case that returns a meta-shaped object and asserts both display.meta and display.result hold their own distinct values. Also add the real-LLM E2E harness at workflow-p4a-meta-live.live.test.ts (6 scenarios: meta+agent, no-meta, malformed-meta short-circuit, body-throw with meta preservation, parallel() fan-out with meta phases, pipeline() multi-stage with meta phases). The suite is gated by DASHSCOPE_API_KEY — describe.skip when absent, so CI without the env shows 0 tests in this file rather than failing. Verified locally 6/6 against qwen3-coder-plus via DashScope OpenAI-compatible endpoint. Final test count: 129/129 (89 sandbox + 34 tool + 6 live). * fix(core): P4a meta-literal Promise crash + live-test typecheck + prettier (QwenLM#4721) Round 3 review fixes: 1. **(Critical, wenshao R1)** A Promise — typically from `import('node:fs')` inside a meta literal — used to crash the host process. `runInContext` evaluates the literal synchronously and returns; `validateMeta` drops the non-contract field silently; the workflow returns its result; THEN the dangling unhandled rejection terminates the process under Node's default `--unhandled-rejections=throw`, decoupled from the run that triggered it. Wenshao reproduced on Node 22.22 with: export const meta = { name:'x', description:'d', extra: import('node:fs') } return 1 → run returns 1, process exits with code 1. Mitigation: after `vm.Script(...).runInContext(...)`, walk the eval result recursively, call `.catch(() => {})` on any thenable to mark the rejection handled, and throw an explicit "meta values must not be Promises" so the malformed meta is rejected before validation continues. Recursion covers `phases[]` entries embedding `import()` below the top level. Two RED-first regression tests in workflow-sandbox.test.ts (top-level + nested-in-phases). 2. **(Critical, wenshao R2/R3)** `tsc --noEmit` failed with 11 errors in the new live E2E test file, blocking CI Lint + all 3 Test jobs: - TS2459 (L36): `WorkflowAgentOpts` is exported from `workflow-sandbox.js`, not from `workflow-orchestrator.js` — fixed import path. - TS2322 (L108/165/220): typing `liveDispatch` as `WorkflowAgentDispatch` widens the return to `string | object`, which doesn't fit `lastText: string`. Dropped the type annotation; the inferred `Promise<string>` is still assignment-compatible with `WorkflowAgentDispatch` (string ⊂ string | object). - TS2345 (×6): `WorkflowRunRequest.args` is required (`args: unknown`, not optional). Added `args: undefined` to every `orch.run({ script })` call. 3. Prettier: `--write` on the 4 touched files. R2 also flagged this; pre-commit lint-staged would normally cover it but the live test file's TS errors short-circuited it. Final local verification: - `tsc --noEmit`: 0 errors - 209/209 tests pass across workflow-sandbox + workflow-orchestrator + workflow.test.ts + live (6 scenarios against qwen3-coder-plus via DashScope) * feat(core+cli): Workflow P4b — /workflows command + phase-tree UI + WorkflowRunRegistry (QwenLM#4721) P4b completes phase P4 of the Dynamic Workflows port. P4a (already on this branch, commits 5b56c39 / 55c23a0 / 402df8f) locked the meta contract: outcome.meta / err.meta / display payload. P4b adds the consumer side — visible workflow runs in the TUI. ## Core (4 changes, 1 new file) - `TaskKind` widened in `packages/core/src/agents/tasks/types.ts` from 3 → 4 variants (adds `'workflow'`). `TaskState` union picks up `WorkflowTask` automatically. - New `WorkflowRunRegistry` (`packages/core/src/agents/workflow-run- registry.ts`) — sibling of `BackgroundTaskRegistry` / `BackgroundShellRegistry` / `MonitorRegistry`. Same register / cancel / get / list / on('statusChange') shape; per-kind state holds runId, meta, current phase, phase history, dispatch counters, recent logs. Eviction: `MAX_RETAINED_TERMINAL_WORKFLOWS = 10` mirrors monitor cap. - `Config.getWorkflowRunRegistry()` exposed via the same Object.create override pattern as the other registries. - `WorkflowOrchestratorEmitter` interface added to workflow-sandbox.ts — fires `phaseStarted` (from sandbox safePhase), `agentDispatched` / `agentCompleted` (from orchestrator countedDispatch), and `logAppended` (from sandbox safeLog). Defensive try/catch around every emit so a subscriber error never bubbles into the script. Orchestrator accepts optional `runId` in WorkflowRunRequest so callers can pre-generate the id and register the run BEFORE run() resolves. - `WorkflowTool` now registers the run with the registry at execute() start, wires the emitter to the registry's update methods + the tool's _updateOutput callback, flips `canUpdateOutput` to `true` for live phase-tree rendering, and routes terminals to registry.complete / fail / cancel (cancel on signal.aborted so user intent stays distinct from script bugs). - `WorkflowRunRegistry` exported from core/index.ts. ## CLI (5 changes, 2 new files) - `BackgroundTasksPill.tsx` `KIND_NAMES` gains `workflow: { singular, plural }`. Counts accumulator + sort order updated: `shell → agent → monitor → workflow → dream` (user-initiated before system-initiated). - `useBackgroundTaskView.ts` subscribes to the workflow registry alongside the existing three; `entryId` switch adds `case 'workflow': return entry.runId`; cleanup unsubscribes. - `BackgroundTasksDialog.tsx` adds `WorkflowDetailBody` (inline, matches MonitorDetailBody style) — renders workflow name, description, status, runtime, current phase, agent dispatch counts (M/N), the phase tree (capped at MAX_VISIBLE_PHASES=20 with "+N more above"), and the log tail (capped at MAX_VISIBLE_LOG_LINES=10). rowLabel switch surfaces `[workflow] <name> · <phase> (M/N)`. DetailBody + statusVerb switches gain workflow cases. - `BackgroundTaskViewContext.tsx` cancelSelected: `case 'workflow': registry.cancel(runId, Date.now())`. Idempotent with the WorkflowTool's signal.aborted catch path. - `BackgroundTasksDialog.test.tsx` entryId mock gains workflow case. ## New /workflows slash command - `packages/cli/src/ui/commands/workflowsCommand.ts` + tests. Bare `/workflows` lists active + completed runs (running first, then terminal by endTime DESC). `/workflows <runId>` opens a per-run detail dump (meta block, status, runtime, phase tree, recent logs, errors). - Gated by `Config.isWorkflowsEnabled()` in BuiltinCommandLoader — command vanishes from typeahead when the flag is off. Already- defined env-var overrides (`QWEN_CODE_ENABLE_WORKFLOWS` opt-in, `QWEN_CODE_DISABLE_WORKFLOWS` kill switch) inherited for free. - Interactive mode adds a "Tip: focus the Background tasks pill" redirect; non-interactive / acp modes omit the tip since they have no dialog. ## Scope deferrals - **ACP daemon protocol widening** (acp-bridge bridgeTypes / status / tasksSnapshot) is deferred to a follow-up PR. Workflows remain invisible to SDK + web-shell consumers in P4b; the CLI-internal surface is complete. - **Phase-tree token rollup** (per-phase token totals in the detail body) needs P5's budget tracker. The infrastructure (registry records, emitter fire sites) is ready for the column when P5 lands. - **Save / inspect subcommands** (`/workflows save <runId>` to materialize a script) are future enhancements; the slash command ships with list + detail only. ## Verification - 223/223 tests pass on the workflow surface — 14 new registry tests, 6 real-LLM E2E scenarios against qwen3-coder-plus (DashScope), plus all existing P3/P4a tests continuing to pass with the new emitter wiring. - 73/73 CLI tests pass across BackgroundTasksPill, BackgroundTasks Dialog, useBackgroundTaskView, workflowsCommand. - `tsc --noEmit` clean (0 P4b errors in core + cli). - `prettier --check` + `eslint` clean on all touched files. * fix(core): bound rejectThenablesInMeta against cyclic meta input (QwenLM#4721) Round 4 review fix. **(Suggestion, wenshao R4)** The R3 thenable walker recursed without a cycle guard. A meta literal that builds a cyclic object via spread overflows the call stack: export const meta = { name: 'x', description: 'y', ...(function () { const a = {}; a.self = a; return a; })(), } vm-eval returns the cyclic object cleanly; `rejectThenablesInMeta` walks `Object.values(...)` and recurses into `a.self === a` forever, producing `RangeError: Maximum call stack size exceeded`. The walker exists to reject Promises before they leave a dangling rejection, but the walk itself must terminate on any shape vm-eval can return — not just on the happy-path acyclic shape. Fix: thread an optional `seen = new WeakSet<object>()` parameter, early-return on `seen.has(value)`. Bounds the recursion against both cycles AND shared subgraphs (where the same node is reached through multiple keys), and keeps the walker O(N) on the eval'd size. Two RED-first regression tests: - Direct self-reference via spread: `{ ...{self: itself} }` - Cycle reached through nested arrays/objects: `{ ...{items: [{ref: outer}]} }` Both previously threw RangeError; both now succeed (validateMeta silently drops the non-contract `self` / `items` fields, so the returned meta is just `{ name, description }` — only reachable if the walker terminates first). `validateMeta` does NOT recurse into nested objects (it walks the top-level contract fields + iterates `phases[]` one level deep with direct property access), so no sibling drift — only the thenable walker needed the guard. * test(cli): stub isWorkflowsEnabled in BuiltinCommandLoader mock config (QwenLM#4721) CI fix for c3f9d84 (Workflow P4b). P4b added a gated `workflowsCommand` to BuiltinCommandLoader: this.config?.isWorkflowsEnabled() ? workflowsCommand : null, The optional-chain only guards `config` being null/undefined — once config is truthy, `.isWorkflowsEnabled()` invokes the method directly. The existing `mockConfig` in BuiltinCommandLoader.test.ts stubbed `isLspEnabled` / `getFolderTrust` / `getManagedAutoMemoryEnabled` but never `isWorkflowsEnabled`, so the new call hit `undefined()` and threw `TypeError: this.config?.isWorkflowsEnabled is not a function`. 10 tests (×3 OS) red on `e9ad07683` for this single reason. Add `isWorkflowsEnabled: vi.fn().mockReturnValue(false)` to the mock, matching the existing pattern. Default to `false` so the loader does not add `workflowsCommand` to the assertions that count exact builtin output — those tests are unchanged. * test(core): cover P4b registry integration + orchestrator emitter (QwenLM#4721) Round 5 fix for the two Critical findings on the P4b commit. ## workflow.test.ts — registry integration seam (+3 tests) \`fakeConfig()\` returns \`{}\`, so \`config.getWorkflowRunRegistry?.()\` short-circuits to undefined in every existing test. The whole P4b integration path inside \`WorkflowTool.execute()\` — \`register()\` on start, the emitter closure firing into the registry, post-run \`complete()\`, catch-arm \`fail()\` / \`cancel()\` branching — is never exercised. Add a \`configWithRegistry()\` helper that builds a config holding a real \`WorkflowRunRegistry\` and returns the registry handle for inspection. Three new tests pin: - **success path**: registry entry transitions to \`completed\` with meta synthesised from \`meta.name\` (the tool fast-tracks description = meta.name when default = runId), correct phases array, agent counts \`1/1\`, script result mirrored, \`endTime\` set. - **failure path**: registry entry transitions to \`failed\`, error message recorded verbatim, phases up to the throw preserved. - **abort path**: pre-aborted signal causes the catch arm to record \`cancelled\` (not \`failed\`) so the dialog distinguishes user-initiated stops from script bugs. ## workflow-orchestrator.test.ts — emitter callbacks (+3 tests) The \`emitter\` field on \`WorkflowRunRequest\` and its firing sites (sandbox \`safePhase\` / \`safeLog\`, orchestrator \`countedDispatch\` before + after) are the only channel keeping the registry record in sync with the live run. Three new tests pin: - **happy-path ordering**: with all four callbacks wired to an event log, the script \`phase('Plan') → log('starting') → agent → phase('Build') → agent\` emits seven events in expected order with expected payloads (\`label\` threaded through both \`agentDispatched\` and \`agentCompleted\`). - **rejection path**: dispatch throwing \`dispatch-boom\` fires \`agentCompleted(label, 'dispatch-boom')\` — pins the symmetric emit-on-throw at workflow-orchestrator.ts:1124 catch arm. - **defensive try/catch**: every callback throwing should be swallowed so orchestration still completes. Pins each emit site's try/catch wrapper individually. Total: 6 new tests, all green. typecheck 0, prettier clean. * fix(core+cli): R7 review fixes — 6 substantive + tmux re-verified (QwenLM#4721) Wenshao's R7 review (with real build + tmux verification on the merged state) approved the PR but surfaced 6 valid findings. All fixed, all RED-first tested, all verified end-to-end against qwen3-coder-plus via DashScope. ## 1. Dialog-cancel drops accumulated logs (Critical) `registry.setRecentLogs(...)` previously guarded `status === 'running'` only. Dialog-initiated cancel marks `status='cancelled'` synchronously BEFORE the tool's catch arm tries to write logs — so cancelled runs always showed an empty Logs section in the dialog. Allow the write after a `'cancelled'` transition too; keep `'completed'` and `'failed'` as final-state rejects. 2 regression tests: cancel-then-logs-still- writes, and complete/fail-still-reject. ## 2. WorkflowRunRegistry missing session-reset wiring (Critical) Sibling drift miss from P4b: `BackgroundTaskRegistry` / `BackgroundShellRegistry` / `MonitorRegistry` all exposed `reset()` + `abortAll()`, and `backgroundWorkUtils` (`hasBlockingBackgroundWork`, `resetBackgroundStateForSessionSwitch`) wired all three. `Workflow RunRegistry` had neither. Result: `/clear` and session-resume ran while a workflow was mid-run (orphaned dispatch loop), and terminal rows leaked from session to session in the pill / dialog / `/workflows` list. Added `hasRunningEntries()`, `reset()` (drops entries, no controller touch), `abortAll()` (cancels every running entry + aborts its controller). Wired into both `backgroundWorkUtils` helpers + updated their tests for the 4-sibling shape. ## 3. Phase dedup inconsistency — sandbox vs registry (Critical) `phase('X'); phase('X')` previously yielded `outcome.phases = ['X','X']` (sandbox `safePhase` unconditional push) but `entry.phases = ['X']` (registry `onPhaseStarted` collapsed). The same run showed different phase counts in the terminal `returnDisplay` JSON vs the live UI. The `agent({phase})` wrapper already deduped (`__b.lastPhase()`); my docstring on `safePhase` claimed it deduped too, but it didn't. Fix at the sandbox layer (single source of truth): `safePhase` skips when `phases[last] === t`. Registry-side dedup is now redundant but harmless (defense in depth, doesn't double-collapse). Updated test in workflow-sandbox.test.ts pins `phase('X'); phase('X'); phase('Y'); phase('X')` → `['X','Y','X']`. ## 4. /workflows tip pointed at non-functional path (UX/docs) `/workflows` tip text said *"focus the Background tasks pill in the footer (use ↓ from an empty composer) and press Enter for the interactive dialog with phase tree + live updates."* But `setPillFocused(true)` doesn't exist anywhere in the codebase (confirmed by wenshao's grep, and reproducible on my own tmux runs where `↓ Enter` never opened the dialog — I previously misattributed to a tmux limitation). The dialog IS reachable through other paths but the tip's specific instructions are wrong. Soften the tip to point at the actually-working text-mode detail view: `Tip: use /workflows <runId> for the per-run detail view (name, description, phase tree, recent logs).` — same information, working instructions. ## 5. `runId` validation comment was aspirational (docs) Comment on `workflow-orchestrator.ts` `run()` claimed *"validates the shape (`wf_<hex>`)"* but the code is `const runId = req.runId ?? generateRunId();` — no validation. Caller (`WorkflowTool`) does use the same `wf_<8hex>` generator as `generateRunId()`, so the behavior is safe in practice. Fixed the comment to describe what the code actually does (trusts the caller, no validation). ## 6. Duplicate extractAndStripMeta test (test hygiene) Two tests at workflow-sandbox.test.ts:227 and :242 used identical source `{ name: args.x, description: 'd' }` — copilot R1 originally flagged this, I declined as bot finding, wenshao re-confirmed. The intent was to pin two distinct things: (a) generic unknown identifier throws, (b) the bridge global `args` specifically is not reachable. Updated the first test to use `totallyUnknown` (a genuine unknown name) and kept the second as the explicit `args` regression — now the two tests pin different things. ## Verification - 231/231 core workflow tests pass (registry + sandbox + orchestrator + tool) — +6 new from R7 RED-first regression tests - 81/81 CLI ripple tests pass (pill + dialog + hook + command + backgroundWorkUtils) - tsc 0 errors on core + cli (after rebuilding core dist for the new registry methods) - prettier + eslint clean on all touched files - **tmux re-verified end-to-end** against qwen3-coder-plus via DashScope on a fresh `npm run bundle`: - Phase dedup: `phase("Phase A"); phase("Phase A")` → `outcome.phases = ["Phase A", "Phase B"]` (was `["Phase A", "Phase A", "Phase B"]` pre-fix) — confirmed both in the tool result JSON AND in `/workflows wf_xxx · 2 phases` - New `/workflows` tip text rendered as expected, no more advertising broken pill focus path - `/workflows <runId>` detail dump still works: name, status, runtime, phases tree, agent counts * test(core): R7 dialog-cancel race integration test (QwenLM#4721) The unit test in workflow-run-registry.test.ts pins the setRecentLogs guard widening in isolation. This integration test stands up the full production wiring — real WorkflowTool, real WorkflowRunRegistry, real sandbox, real emitter — and reproduces the exact dialog-cancel race that the R7 fix targets: 1. Start execute() with a controllable dispatch that hangs until externally rejected. 2. Wait for the run to register + the dispatch to be in flight + at least one log() call to have accumulated. 3. Simulate the dialog: call registry.cancel(runId) directly. This is the exact entry point cancelSelected() uses in BackgroundTaskViewContext.cancelSelected for kind='workflow'. 4. Cascade the dispatch rejection (the production path: the registry's abortController abort propagates through dispatchController → the orchestrator's limiter → the in-flight dispatch). 5. Await execute() — the tool's catch arm runs setRecentLogs with the accumulated logs. 6. Assert: status='cancelled' AND recentLogs contains the script's log('before agent dispatch') entry. RED→GREEN verified: temporarily reverted the setRecentLogs guard to the pre-R7 single-state form, the test failed with `AssertionError: expected 0 to be greater than 0` (recentLogs was empty because the guard rejected). Restored fix, test passes. Production reachability note: the dialog itself is not currently reachable through the TUI pill focus chain (setPillFocused(true) does not exist anywhere in the codebase — wenshao R7 verification finding #1, pre-existing infra gap out of P4 scope). This integration test is the closest available real-scenario verification for the fix without modifying out-of-scope code; the test drives the EXACT registry.cancel + dispatch rejection + catch-arm sequence the dialog would trigger. * test(cli): stub getWorkflowRunRegistry in clearCommand + useResumeCommand mocks (QwenLM#4721) CI fix for b53bc4e (the R7 fix commit). R7 (commit b53bc4e) wired WorkflowRunRegistry's new reset() / abortAll() / hasRunningEntries() methods into backgroundWorkUtils.ts (hasBlockingBackgroundWork + resetBackgroundStateForSessionSwitch). clearCommand.ts and useResumeCommand.ts call both utils, but their mock configs didn't stub getWorkflowRunRegistry — so once the util started calling it, every clearCommand test threw `TypeError: config.getWorkflowRunRegistry is not a function`. CI ubuntu/macos/windows × 10 tests × clearCommand.test.ts went red. This is the same sibling-drift miss as the BuiltinCommandLoader fix in 2491911 (R7 pre-cursor): I added a new Config method, every existing mock that ships a Config-shaped object goes stale until stubbed. Fix: add the same `getWorkflowRunRegistry` stub shape to: - clearCommand.test.ts: 3 sites (default mock + non-interactive mock + blocked-background mock) - useResumeCommand.test.ts: 4 sites (all 4 mock configs) Stub shape mirrors the 3 sibling registries' interfaces exposed via backgroundWorkUtils: `hasRunningEntries`, `reset`, `abortAll`. Returns false / vi.fn() so default behavior matches "no workflow running" + "reset is observable". Existing tests that exercise the blocked-background path (hasUnfinalizedTasks: true) keep working because workflow's hasRunningEntries=false still allows the agent-side block to trigger. Verification: 24/24 in clearCommand+useResumeCommand pass locally; the 7-file P4 + impacted suite pass 105/105 (registries + commands + hooks + dialog + pill + workflowsCommand + backgroundWorkUtils).

QwenLM#5231) * feat(core,cli): workflow tool token budget + per-run UI surfacing (P5) P5 of the Dynamic Workflows port (QwenLM#4721): per-run output-token budget for the Workflow tool, wired through the orchestrator dispatch gate, WorkflowRunRegistry, BackgroundTasksDialog phase tree, and the /workflows slash command. Also introduces a one-time usage banner the first time a workflow runs in a session, gated by the skipWorkflowUsageWarning setting. Knobs: QWEN_CODE_MAX_TOKENS_PER_WORKFLOW=<int> env, per-run cap skipWorkflowUsageWarning: true setting, suppress banner Budget gate semantics: SOFT cap, not pre-commit reservation. Gate is checked at dispatch entry, so concurrent fan-out (parallel / pipeline) can overshoot by up to (concurrency_window - 1) x per_dispatch_tokens before the first overshoot dispatch throws WorkflowBudgetExceededError. Matches upstream Claude Code 2.1.168 semantics. Operators sizing the cap should subtract the overshoot margin. Implementation: - WorkflowBudgetImpl (workflow-budget.ts) + env resolver with HARD_MAX_TOKENS_CEILING=100M ceiling on the env override. - WorkflowBudgetExceededError carries runId / budgetTotal / spent. - countedDispatch budget gate + onTokens callback feeding budget.recordSpent from getExecutionSummary().outputTokens. - WorkflowOrchestratorEmitter.budgetUpdated event; fires after each successful dispatch, skipped on rejection and when budget is null. - WorkflowTask gains tokensSpent / tokenBudgetTotal / perPhaseTokens fields; WorkflowRunRegistry.onBudgetUpdated attributes deltas to currentPhase at fire time and re-emits statusChange. - WorkflowRunRegistry.shouldShowUsageWarning latch fires once per registry instance; survives reset(). - WorkflowTool wires WorkflowBudgetImpl.fromEnv, threads onTokens into createProductionDispatch, mirrors budget into the registry via the emitter, and prepends the usage banner on the SUCCESS path only. - WorkflowDetailBody + /workflows listing + live phase-tree render budget chip (tokens / cap) and per-phase token totals. Verification (270 + 4 + 4 = 272 core + 42 cli): - workflow-budget.test.ts (18) + workflow-orchestrator.test.ts (+8 P5 + budget-gate + budgetUpdated emitter) - workflow-run-registry.test.ts (+10 P5: budget fields, latch, per-phase attribution, no-op on terminal entries) - workflow.test.ts (+4 P5: banner appears once, suppressed by setting, failure-path latch unchanged, fail-then-success re-emits banner) - workflowsCommand.test.ts (+4 P5: row chip capped/uncapped, detail tokens/cap/per-phase chips) - BackgroundTasksDialog.test.tsx unchanged (32 still pass) - Real-LLM E2E (DashScope qwen3.7-plus): tmux session driving Workflow tool, banner verified in returnDisplay, /workflows shows tokens 0 / cap (no cap) on uncapped run, banner suppression on 2nd run confirmed (latch consumed exactly once). Self-review round 1 fixes: - "hard ceiling" docstring softened to "soft cap" with per_dispatch x concurrency_window overshoot bound documented; banner copy aligned ("soft cap" instead of "hard ceiling"). - Attempted failure-path banner reverted after coreToolScheduler inspection: createErrorResponse hard-codes resultDisplay = error.message whenever result.error is set, so a failure-path banner would have been invisible AND would have silently flipped the registry latch, causing the next successful run to skip the banner too. Failure path now does not touch the latch; failure-path test asserts the fail-then-success run still gets the banner. - skipWorkflowUsageWarning setting placement aligned with skipNextSpeakerCheck sibling under settings.model.*. - QWEN_CODE_MAX_TOKENS_PER_WORKFLOW=0 documented as "treated as unset" with explicit pointer to QWEN_CODE_DISABLE_WORKFLOWS=1 for the "no workflows at all" intent. Refs QwenLM#4721. * fix(core,cli): close P5 review round 1 — token tracking gaps + UI polish (PR QwenLM#5231) Addresses 4 Critical + 7 Suggestions from qwen-code-ci-bot's multi-agent review: Critical fixes (orchestrator core): - #1 (workflow-orchestrator.ts): schema-mode success path was missing the onTokens call entirely, so structured-output agents never recorded against the budget. Lifted the token report to a single `reportTokens` helper invoked once after `subagent.execute()` returns, BEFORE the schema/non-schema branch. Both fast-path and override-path dispatch now hit the same reporting site regardless of terminate mode. - #2 (workflow-orchestrator.ts): the entry budget gate in countedDispatch was bypassed by `parallel()` batches — all N thunks fire-check-queue in a single microtask burst with spent=0, so every queued dispatch passed the gate before any could record tokens. Added a SECOND gate inside the limiter.run callback so queued thunks observe budget mutations from already-completed in-flight dispatches at slot-acquire time, restoring the documented overshoot bound of (concurrency_window - 1) × per_dispatch_tokens (previously up to N × per_dispatch_tokens for a single `parallel()` of N items). - #3 (workflow-orchestrator.ts): CANCELLED / TIMEOUT / MAX_TURNS / ERROR terminations threw without recording tokens, so failed dispatches burned budget silently. Same `reportTokens` lift fixes this — tokens are now read before the terminate-mode check on both paths. - #4 (workflow-orchestrator.ts): added debugLogger.warn at both gate sites (entry + intra-limiter) for budget-rejected dispatches. Suggestion fixes: - #5 (workflow.ts): `resolveUsageBanner` JSDoc still said "Called from BOTH the success and failure paths" after the earlier failure-path revert. Corrected to "SUCCESS path only" with the scheduler-override rationale moved into the docstring. - #6 (workflowsCommand.ts, BackgroundTasksDialog.tsx): null-sentinel perPhaseTokens (tokens spent before the first phase() call) was attributed by the registry but never rendered. Detail view + phase tree now surface a "(no phase)" row when the null-key bucket has spend. - #7 (workflowsCommand.ts, BackgroundTasksDialog.tsx): use the existing `formatTokenCount` helper from `cli/ui/utils/formatters.ts` (the same surface statusLinePresets and TurnCard use) so token counts render as `1.5k / 10k` instead of raw integers. - #8 (workflow-run-registry.ts): `onBudgetUpdated` no longer fires `emitStatusChange` when neither tokensSpent nor tokenBudgetTotal changed. Production code fires `budgetUpdated` after every successful dispatch including zero-output-token ones; gating the emit avoids a no-op UI re-render burst on those. - #11 (workflow.ts): final returnDisplay JSON now includes the `tokens` block whenever any usage is reported OR a cap is set, aligned with `buildLivePhaseTreeDisplay` (was only included when spend > 0, inconsistent with the live render). Test additions: - workflow-budget.test.ts: unchanged (18). - workflow-orchestrator.test.ts: +6 R1 tests (parallel-batch overshoot regression for #2, GOAL+CANCELLED/MAX_TURNS/TIMEOUT/ERROR token recording for #3 via createProductionDispatch, schema-mode success token recording for #1, no-onTokens crash safety). Mock subagent extended with getExecutionSummary + nextOutputTokens to drive these. - workflow-run-registry.test.ts: +1 R1 test for #8 emit gating; rewrote the backwards/zero-delta test to the new monotonic-spent contract. - workflow.test.ts: +1 R1 test for #10 (capped banner shape — was untested; only the uncapped shape had coverage). - workflowsCommand.test.ts: +1 R1 test for #6 null-sentinel surfacing. Updated assertions for #7 formatTokenCount output (`1.5k/10kt`). Total: 282 core tests passing (+10 R1), 43 CLI tests passing (+1 R1), 0 lint, 0 typecheck for workflow-touching files. Real-LLM tmux + JSON E2E reconfirmed end-to-end (banner now says "soft cap", display payload shape unchanged, run registers + completes cleanly). #9 fold: the parallel-batch overshoot test serves as the regression guard for the intra-limiter gate fix in #2. #7 partial: workflowsCommand.ts and BackgroundTasksDialog.tsx are the only two `tokens` render sites in P5; both updated. Other token-bearing surfaces (statusLinePresets, TurnCard) already use the helper. PR: QwenLM#5231 * fix(core,cli): close P5 review round 2 — UI emit dedup + error tail + dialog coverage (PR QwenLM#5231) 3 real findings from qwen-code-ci-bot's round 2 review (the other 11 findings on the same review were already addressed by R1 commit 6c5de81 — the bot used a stale snapshot that did not include R1). Fixes: - #12 (workflow.ts): every dispatch completion produced TWO `safeEmitUpdate` calls — once in the `agentCompleted` handler, once in the `budgetUpdated` handler that fires right after. Over a 1000-agent workflow that's 2000 TUI redraws when 1000 suffices. Dropped the `safeEmitUpdate` call from the `agentCompleted` handler and kept it in `budgetUpdated`; the orchestrator fires the two events back-to-back, so the deferred render shows both updates atomically. Production `WorkflowTool.execute()` always wires `WorkflowBudgetImpl.fromEnv()`, so `budgetUpdated` always fires — test paths that omit budget use the injected dispatch shape and don't exercise this emitter wiring. - #14 (workflow-budget.ts): the WorkflowBudgetExceededError message carried an advisory tail — "Increase QWEN_CODE_MAX_TOKENS_PER_WORKFLOW or unset it to remove the cap" — that reaches the LLM via `tool_result`. The model could surface this to the user and effectively coach them to remove the operator-set budget policy. Trimmed to the factual portion only. Operators can still find the env knob via the `debugLogger.warn` at both gate sites that names `MAX_TOKENS_PER_WORKFLOW_ENV` verbatim. - #15 (BackgroundTasksDialog.test.tsx): WorkflowDetailBody had no rendering test coverage. Added 4 cases under a new R2 #15 describe: capped M/N chip with per-phase tally, uncapped plain-spent + zero- chip suppression, hidden chip when both spend and cap are zero/null, and null-sentinel `(no phase)` row. Declined / declined-with-counter-evidence: - #13 (workflow-budget.ts threat-model docstring): bot claimed the overshoot bound is off-by-one — `concurrency_window × per_dispatch` rather than `(concurrency_window - 1) × per_dispatch`. The latter is the correct tighter upper bound: when the gate first tips, the tipping dispatch's own tokens are already counted in `spent`, and only `concurrency_window - 1` other in-flight dispatches remain to add overshoot. The looser bound the bot suggests would mislead operators into oversized safety margins. Test count: 282 → 283 core (+1 R2 #14 negative assertion), 42 → 47 CLI (+5 R2 #15 + null-sentinel coverage). 0 lint, 0 typecheck for workflow-touching files. PR: QwenLM#5231 * fix(core): close P5 review round 3 — finally-bracket execute(), error-arm budgetUpdated, gate-before-count (PR QwenLM#5231) 3 fixes for round 3 review. wenshao (human maintainer) caught a real production-path token leak that R1's `R1 #3` test missed; bot also found that R2 #12 (UI emit dedup) left the error arm with zero re-renders. Critical fixes (orchestrator core): - #6 (wenshao): `reportTokens` was on the line AFTER `await subagent.execute(...)` at both dispatch sites (fast path :353 + override path :642) — NOT in a `finally`. `AgentHeadless.execute()` re-throws on real reasoning-loop failure (`agent-headless.ts:287-294`), so the production ERROR path skipped `reportTokens` entirely and the dispatch's burned tokens leaked. Wrapped `await subagent.execute()` in `try { ... } finally { reportTokens(...) }` at both sites. `getExecutionSummary()` is safe to read inside the throw path because `AgentHeadless.execute()`'s own outer `finally` finalizes stats before the throw propagates. R1's `R1 #3` test passed only because the mock execute() RETURNED with ERROR mode (the rare `createChat` early-return); the production reasoning-loop throw was untested. Test pattern: R3 #6 tests now mock `execute()` to THROW directly, asserting `onTokens` still fires for both fast path and override path (sibling-drift coverage). - #1 (bot): with R2 #12's UI-emit dedup, the error arm of `countedDispatch` fired `agentCompleted` (no `safeEmitUpdate`) and NEVER fired `budgetUpdated` — producing ZERO UI re-renders per failed dispatch. The registry's `tokensSpent` / `perPhaseTokens` also diverged from `budget.spent()` because the host counter advanced (via the reportTokens-in-finally above) while the registry never saw it. Error arm now also fires `emitter?.budgetUpdated?.()` with the post-throw spent + total. Updated R1's "does NOT fire on dispatch rejection" test to assert the new contract (DOES fire, with the cumulative spent) — that test only passed before because the mock dispatch threw without ever calling `budget.recordSpent`, masking the production behavior. - #7 (wenshao, suggestion → accepted): `agentCount += 1` ran BEFORE the budget gate. After budget exhaustion, every subsequent `agent()` call still incremented `agentCount`, eventually tripping the agent-cap and surfacing the WRONG terminal error (`Workflow exceeded the maximum of N agent() calls per run`) when the real cause was budget exhaustion. Moved the budget gate above the `agentCount += 1`. Also keeps `agentCount` and `agentsDispatched` (registry counter) counting the same set of calls. New test loops 1100 budget-rejected dispatches and asserts the script completes with budget errors only, never agent-cap errors. Declined (round 5 Suggestion bar): - bot #2 (rename `shouldShowUsageWarning` → `tryConsumeUsageWarning`): naming style, R5 → overthinking. - bot #3 (debugLogger on NaN drop in recordSpent): hostile-provider defensive hardening, R5 → overthinking. - bot #4 (debugLogger on negative delta in onBudgetUpdated): same. - bot #5 (triple emitStatusChange per dispatch): efficiency, R5 → overthinking; #1 fix kept the dispatched / completed / budget callback shape, and TUI emits are still 2 per dispatch (the middle one no longer fires safeEmitUpdate per R2 #12). Declined with counter-evidence: - (None this round.) Test count: 283 → 287 core (+4 R3 tests: throw-path fast/override, budgetUpdated on error, agentCount/gate ordering), 47 CLI unchanged. 0 lint, 0 typecheck for workflow-touching files. CI lint failure on this PR is pre-existing main breakage (shellcheck SC2295 in `.github/workflows/qwen-autofix.yml:598` introduced by commit a335f9c, unrelated to this PR's diff) — leaving alone.

Stacks on QwenLM#5661 (type-based tool partition baseline) and QwenLM#5751 (VP mouse foundation). Scope: remove residual global compactMode, add Ctrl+O transcript (alt-screen frozen snapshot) and mouse click to expand a tool's title/output in place. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * feat(tui): remove global compact mode toggle (on top of QwenLM#5661 partition baseline) Builds on QwenLM#5661's type-based tool partition. Removes only the residual global compactMode switch, keeping the partition baseline intact: - ToolGroupMessage: showCompact = (compactMode || allComplete) → allComplete - delete CompactModeContext, mergeCompactToolGroups (isForceExpandGroup / compactToggleHasVisualEffect no longer used once the cross-group merge and the Ctrl+O toggle are gone) - MainContent: drop the compactMode-gated merge path; mergedHistory = visibleHistory - remove TOGGLE_COMPACT_MODE binding/matcher, ui.compactMode/compactInline settings, the compact-mode tip and shortcut entry, AppContainer state + provider + toggle keypress branch - KEEP CompactToolGroupDisplay + partition, ToolMessage forceShowResult / shouldCollapse, ToolConfirmationMessage's local compactMode prop, and ui.compactMode in WEB_SHELL_SETTINGS (web shell is a separate surface) typecheck + affected suites green (224 tests). Ctrl+O is a temporary no-op until the TranscriptView lands. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * feat(tui): Ctrl+O opens a frozen alt-screen transcript full-detail view Adds the keyboard half of the Ctrl+O redesign on top of the QwenLM#5661 partition baseline: - fullDetail render path (HistoryItemDisplay → ToolGroupMessage): fullDetail composes into thinking `expanded`, and on tool groups forces showCompact=false + forceShowResult=true + uncapped height — so every block renders in full. - new TranscriptView: an AlternateScreen overlay (disabled in VP mode where Ink already owns the alt screen) rendering a frozen snapshot (history length + a pending copy) through ScrollableList with fullDetail, reusing QwenLM#5751's keyboard/wheel/scrollbar scrolling. Adaptive estimatedItemHeight for the taller full-detail rows. - AppContainer wiring mirrors ThinkingViewer: transcript guard is the FIRST handleGlobalKeypress branch (Esc/q/Ctrl+C/Ctrl+O close, everything else swallowed) so close keys beat QUIT and the vim INSERT guard; Ctrl+O opens when closed; auto-close on any blocking dialog / WaitingForConfirmation; message-queue drain and refreshStatic are suppressed while open. - Command.TOGGLE_TRANSCRIPT bound to Ctrl+O. typecheck + 8 suites (268 tests) green. Mouse click-to-expand (per-tool) follows in a later commit. Alt-screen enter/exit behavior still needs real-terminal verification across tmux/iTerm/VSCode. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(tui): repaint normal buffer when transcript closes (no duplicate scrollback) E2E (VHS) caught the design's flagged highest-risk issue: in the legacy <Static> path, closing the alt-screen transcript leaked its full-detail rows into the main scrollback (a duplicate "完整记录 / Transcript" block appeared below the live history). Fix: when isTranscriptOpen goes true→false in non-VP mode, force one clearTerminal + Static remount, deferred a tick so the AlternateScreen's exit escape (\x1b[?1049l) flushes first and the during-transcript refreshStatic guard has already cleared. VP mode keeps its own scrollback via the React tree and is unaffected. Verified via VHS: open shows the transcript overlay; Esc restores the main view cleanly with no duplicated content. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * docs(tui): rebase ctrl-o design doc to QwenLM#5661's type-based partition The design doc was written against an early state-based snapshot of QwenLM#5661 (showCompact = (compactMode || allComplete), whole-group collapse) and even asserted that forceExpandAll / isCollapsibleTool "don't exist". The merged QwenLM#5661 is type-based partition and those symbols are its core. Rewrite the affected sections to match the shipped baseline: - §1/§2: baseline described as type-based partition (collapse read/search/list via isCollapsibleTool, render mutation tools individually); compactMode no longer affects tool rendering. Added a revision note. - §3.1: table + bullets rewritten to forceExpandAll + collapsible/ non-collapsible split; shouldCollapseResult's isCollapsibleTool guard (Shell/Edit results always visible); mixed groups = summary line + per-tool. - §4.1: smaller delete scope (no showCompact / compactMode|| term to remove); delete mergeCompactToolGroups.ts; keep web-shell ui.compactMode passthrough. - §4.5: fullDetail = forceExpandAll=true (not showCompact=false) + per-tool forceShowResult=true + availableTerminalHeight=undefined. - §4.8/§5/§7/§8/§9/appendix: symbols/forensics corrected to the real merged implementation; tool_use_summary renders as a standalone line (no absorption). Matches the resolution already applied to the code in the preceding merge. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * docs(tui): fix factual nits from cross-audit of the ctrl-o design doc Three independent audits confirmed the doc is now faithful to the merged QwenLM#5661 type-based partition; they surfaced three concrete fixes: - CATEGORY_ORDER: corrected to the real array order search/read/list/command/edit/write/agent/other (was listed as command/read/edit/write/search/list/agent/other). - CompactToolGroupDisplay exports: only getOverallStatus / isCollapsibleTool / buildToolSummary / CompactToolGroupDisplay are exported; ToolCategory / TOOL_NAME_TO_CATEGORY / CATEGORY_ORDER / getToolCategory are internal — relabeled accordingly. - §5.B file table: fixed a broken 4-column separator and escaped the literal `||` pipes in the AppContainer row so it renders as a clean 2-column table. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(tui): don't let fullDetail be bypassed by compact early returns Audit (PR QwenLM#5666) point 2: ToolGroupMessage computed `forceExpandAll = fullDetail || ...` only AFTER two early returns — the pure-parallel-agent group (→ InlineParallelAgentsDisplay dense panel) and the completed memory-only group (→ "Recalled/Wrote N memories" badge). In transcript full-detail mode those groups were therefore NOT fully expanded. Guard both early returns with `!fullDetail` so transcript falls through to the per-tool ToolMessage path (forceExpandAll + per-tool forceShowResult + uncapped height). Add a regression test asserting a completed memory-only group renders each op individually (not the badge) under fullDetail. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * docs(tui): resolve open design decisions from source evidence Settle the two outstanding decision points from the PR audit using the codebase + reference implementations (not preference): - Non-TTY (audit point 3): AlternateScreen has NO isTTY guard today (doc claimed it did — corrected). The TUI is already gated by stdin.isTTY (config.ts:1532), so non-TTY rarely mounts; the only edge is `-i`. Decision: add a process.stdout.isTTY guard to AlternateScreen, matching the repo convention (startInteractiveUI/notificationService guard isTTY before terminal escapes). Doc now marks it "to implement" + test. - Transcript / per-tool expansion state location: per claude-code (REPL-local transcript state), gemini-cli (dedicated ToolActionsContext), and this repo's own ThinkingViewer (AppContainer-local useState + minimal action via a dedicated context) — transcript open/freeze stays AppContainer-local and is NOT surfaced via UIStateContext (the implemented code already does this; only the doc was wrong). Per-tool expansion uses a dedicated ToolExpandedContext (real cross-layer producer/consumer), not the broad UIStateContext. Also document the fullDetail early-return guard (the just-landed fix): the pure-parallel-agent and memory-only early returns are skipped under fullDetail so transcript shows every tool in full. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * docs(tui): align design doc status/scope with current PR (audit follow-up) Latest audit confirms the technical design is implementable and side-effect coverage is sufficient; it flagged status/scope inconsistencies for the doc to serve as an acceptance baseline. Fixes: 1. Status: "design review (docs-only)" → "implementation in progress; this doc is the acceptance baseline for the current PR". Added an implemented-vs-pending status table. 2. Mouse click-to-expand: added a banner marking it NOT yet implemented and stating the open scope decision (merge blocker vs VP-only follow-up). 3. QwenLM#5751 (and QwenLM#5661) dependency: corrected from "OPEN, must merge first" to "already merged into main; branch rebased on top". 4. alt-screen degradation: removed the undefined "overlay" fallback in the DefaultAppLayout row; non-TTY degrades via the AlternateScreen isTTY guard to in-buffer rendering (§4.2), no separate overlay path. 5. Fixed a broken bold marker (`\*\*`) in the AppContainer row. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * docs(tui): scope mouse click-to-expand out as a follow-up Assessed the mouse click-to-expand effort against the real code: it's ~250–400 lines across 4–5 files (ToolExpandedContext + AppContainer wiring + a ClickableToolMessage component — can't call useMouseEvents inside the .map() — + ToolGroupMessage wiring + mouse hit-test tests). More importantly, under QwenLM#5661's type-based partition the collapsed read/search tools are aggregated into a single summary line, so there is no per-tool click target — the click granularity must be redesigned to "click the summary row → expand the whole group". Plus the known SGR-mouse vs native text-selection risk. Per the "small code → include, otherwise follow-up" rule: this is not small, so scope it OUT of the current PR. The current PR delivers Ctrl+O transcript only. Marked §1 goal #4, §4.8 (banner + draft), §9 commit 4, and the status table accordingly; the §4.8 design is kept as a draft for the follow-up PR. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * feat(tui): isTTY guard for AlternateScreen + transcript shortcut/i18n cleanup Completes the remaining in-scope items for the Ctrl+O transcript PR: - AlternateScreen: guard the alt-screen escape writes on `process.stdout.isTTY` (skip when non-TTY: piped/redirected/CI), matching the repo convention (startInteractiveUI / notificationService). Non-TTY now degrades to in-buffer rendering. Adds AlternateScreen.test.tsx (enter/exit on TTY, skip when disabled, skip when non-TTY). - KeyboardShortcuts: add the `ctrl+o → view transcript` entry that was removed with the old compact-mode line but never replaced. - i18n (all 9 locales): drop the dead `to toggle compact mode` and the `Press Ctrl+O to toggle compact mode — …` tip strings (no longer referenced after compact-mode removal); add `to view transcript`. Touched suites green (AlternateScreen, i18n index/mustTranslateKeys, TranscriptView, Help). Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * docs(tui): mark isTTY guard + i18n cleanup as implemented in status table Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(i18n): add TranscriptView strings to all locales TranscriptView.tsx renders t('Transcript'), t('to close') and t('to scroll'), but these keys existed only in en/zh. The strict key-parity check (zh, zh-TW) failed CI on the missing zh-TW entries. Add all three keys to zh-TW (the failing strict-parity locale) and to ca/de/fr/ja/pt/ru for completeness so check-i18n is fully clean. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * docs(ctrl-o): add before/after transcript capture evidence Add VHS-captured screenshots (main-view collapsed vs Ctrl+O transcript expanded) under docs/design/ctrl-o-detail-expand/assets/ and reference them from §3.4 of the design doc.

Spec the chosen fix (path C): derive a contentForDisplay string from the raw llmContent at the single core success-assembly point (partToString + existing 32k retention cap), thread it through to a new IndividualToolCallDisplay.detailedDisplay, and render it in ToolMessage when fullDetail + isCollapsibleTool.

Saved/replayed transcripts get full detail for free (audit #6). - Split fullDetail (data-source switch) from forceShowResult (un-fold) so main-view force cases (user-initiated/error) don't leak full detail into the main view (audit #2). - Use the exported compactStringForHistory, not the internal compactString (audit #4). - Scope by isCollapsibleTool incl. glob, not a hardcoded read/ls/grep list (audit #5). - §3.4: stop claiming the screenshot already shows full output; add a pre-§4.9 caveat and a merge-blocker row in the status table (audit #1). - Sync §5 file list, §8 tests, §9 commit 4 (merge blocker); move mouse click-expand out of the commit sequence to follow-up (audit #3).

Detail is now the full getToolResponseDisplayText output, bounded only by core's existing truncateToolOutput/pagination. - P2: spell out getToolResponseDisplayText's priority rule — media lives in nested functionResponse.parts (not top-level); read response.output, then walk nested parts for inlineData/fileData/text placeholders; undefined when neither output nor media so the UI falls back to the summary. - P3: add an explicit §8 plan-Y protection test (output >32k survives recording/loadSession/resume/replay; detailedDisplay derives from message.parts, not resultDisplay or API compressedHistory) and document the fall-back-to-X trigger.

The TUI compact mode stays retired — it just isn't shown in the TUI dialog. - workspace-settings: restore ui.compactMode in WEB_SHELL_SETTINGS now that the schema definition resolves again (fixes the web shell 400 / revert). - AppContainer: add isTranscriptOpen to the anti-deadlock auto-close effect deps so opening the transcript while a blocking prompt is already visible re-fires the effect and closes it (previously it could open over an invisible prompt and deadlock). - ToolGroupMessage.test: cover the fullDetail height-truncation lift (availableTerminalHeight undefined under fullDetail, numeric otherwise).

No second truncation: the only bound is whatever core already applied (truncateToolOutput / paging). - cli: add derived (non-persisted) `IndividualToolCallDisplay.detailedDisplay`. Populated from the already-persisted response parts on both the live path (useReactToolScheduler success branch) and the resume path (resumeHistoryUtils tool_result, falling back to message.parts for older records). - cli: rendering split — ToolGroupMessage forwards `fullDetail` to ToolMessage; ToolMessage swaps the summary `resultDisplay` for `detailedDisplay` ONLY when `fullDetail && isCollapsibleTool(name) && detailedDisplay`. Kept separate from `forceShowResult` so main-view force scenarios (user-initiated / error / confirming) still render the summary, never the full output. - ACP path needs no change: ToolCallEmitter.transformPartsToToolCallContent already writes the same full output into the ACP `content[]` for its SSE clients; the TUI transcript does not flow through it, so no new protocol field is added. Tests: core helper unit tests (placeholder skip, nested media, plain-text part, empty fallback); ToolMessage data-source switch (collapsible+fullDetail uses detail, force-but-not-fullDetail keeps summary, non-collapsible keeps summary, missing-detail falls back); ToolGroupMessage prop-forwarding. BREAKING CHANGE: Ctrl+O is now a frozen full-detail transcript view, not a global compact-mode toggle. The `TOGGLE_COMPACT_MODE` command and the TUI effect of `ui.compactMode` / `ui.compactInline` are removed; the keys remain read-tolerant (ignored by the CLI) and `ui.compactMode` is still forwarded to the web shell.

Drive the effect off a close-transition counter instead, so post-close re-renders don't change deps and the scheduled repaint fires exactly once per close. - AppContainer: transcript snapshot now mirrors MainContent's `!display.suppressOnRestore` filter, so items collapsed on session resume (ui.history.collapseOnResume) are not re-exposed in the Ctrl+O view. - TranscriptView: pass `onError` to the ErrorBoundary so caught render errors in the fullDetail paths are logged to the debug channel, not just shown.

Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(ctrl-o): address review — plain-text detail, shared placeholder const, resume status guard, scroll hint Four review fixes on the §4.9 transcript work: - ToolMessage: when fullDetail swaps the data source to detailedDisplay (raw file content / grep hits / dir listings), force renderOutputAsMarkdown to false. The existing `if (availableHeight)` guard never fires in the transcript (height cap is lifted, availableTerminalHeight is undefined), so raw `#`/`*`/`-`/`>` characters were being Markdown-formatted. - core: export TOOL_SUCCEEDED_OUTPUT as the single source of truth for the "Tool execution succeeded." placeholder. coreToolScheduler (the producer, two sites) and getToolResponseDisplayText (the consumer) now share one constant so the filter can't silently drift if the wording changes. - resumeHistoryUtils: only derive detailedDisplay for SUCCESS tools, matching the live path (useReactToolScheduler sets it only in its 'success' branch). Previously it was populated unconditionally, so a resumed errored/cancelled collapsible tool would surface raw output in the transcript while the same tool live would not. - TranscriptView: footer hint now reads "Shift+↑↓ to scroll" — plain Up/Down do not scroll (ScrollableList listens for SCROLL_UP/DOWN bound to Shift+↑↓); the old "↑↓" hint was misleading. Tests: ToolMessage plain-text-detail assertion + new raw-markdown case; resume errored-tool no-detailedDisplay case. typecheck/lint/tests green (core scheduler 222, cli suites pass). Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(tui): guard transcript non-TTY output + clear detailedDisplay on compaction Addresses three review findings on the Ctrl+O transcript work: - Non-TTY byte leak: `useMouseEvents` enabled SGR mouse mode (?1002h ?1006h) whenever stdin supported raw mode, ignoring stdout. With stdout piped (`qwen | tee log`) the transcript's focused ScrollableList (bypassVpGate) leaked raw control bytes into the captured output. Gate the enable on `stdout.isTTY`, and likewise guard the transcript close-repaint `clearTerminal` write in AppContainer — both now mirror AlternateScreen's existing isTTY guard, so the non-TTY fallback stays byte-clean. - Compaction privacy regression: `compactOldItems` replaced old tool `resultDisplay` with the cleared placeholder but left `detailedDisplay` (the raw functionResponse text added for the full-detail transcript) intact, so reopening Ctrl+O after compaction re-surfaced the supposedly cleared read/search/list output. Clear `detailedDisplay` wherever `resultDisplay` is cleared, with a regression test. - Docs: keyboard-shortcuts.md still described Ctrl+O as "toggle compact mode"; updated to the open/close full-detail transcript behavior. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * test(tui): report a TTY stdout in ScrollableList mouse-scroll tests The new `stdout.isTTY` gate in `useMouseEvents` (which stops SGR mouse escapes leaking into piped output) left ink-testing-library's fake stdout — which has no `isTTY` — with the mouse pipeline disabled, so the scrollbar-drag and wheel-scroll assertions never received events. Mock ink's `useStdout` to report `isTTY: true` so the pipeline arms exactly as it does in a real terminal; all other ink exports are preserved. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(tui): address Ctrl+O transcript review — q-guard, callback churn, tests, cleanup Resolves the qwen3.7-max /review findings: - Modifier guard on the transcript close key: bare `q` closed the transcript, but Ink reports Ctrl/Alt/Shift+Q as `{ name: 'q', … }` too (Alt arrives as `meta`), so those silently closed it. Guard `!key.ctrl && !key.meta && !key.shift` (Shift+Q is a literal `Q`). - Stable `openTranscript`: it captured `historyManager.history` and `pendingHistoryItems` as deps, both of which change identity every streaming tick, rebuilding the callback — and the whole `handleGlobalKeypress` closure that lists it — on every render during streaming. Read both via refs so the callback is referentially stable. - AppContainer transcript integration tests (the removed TOGGLE_COMPACT tests had no replacement): Ctrl+O installs TranscriptView; Esc / q / Ctrl+C / Ctrl+D close it; Ctrl+Q / Alt+Q / Shift+Q do NOT (modifier guard); arbitrary keys are swallowed and keep it open; a blocking confirmation (WaitingForConfirmation) auto-closes it (anti-deadlock). - Dead i18n string: removed the orphaned 'Press Ctrl+O to show full tool output' key from all 9 locale files (no `t()` reference remained after the compact-mode sweep). - Design doc: replaced the leaked absolute worktree path with a placeholder, and corrected the §6 keybinding-migration note — the codebase has no user-configurable keybinding override surface (`keyMatchers` always uses hardcoded defaults), so there is no persisted `toggleCompactMode` binding to migrate; the startup-detection step is not applicable until such a feature exists. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(tui): escape ANSI in transcript detailedDisplay + gate its extraction Two findings from the qwen3.7-max /review on §4.9: - [Critical] ANSI escape injection: `detailedDisplay` carries raw, un-sanitized tool output (file contents, grep hits, directory listings). The Ctrl+O transcript rendered it straight to <Text> without escaping, so a malicious repo file with embedded terminal control sequences (e.g. `\x1b[?1049l` to drop the alt-screen, OSC 52 for clipboard poisoning) would execute when the transcript opened — and fullDetail lifts the height cap, exposing the whole file. Run it through `escapeAnsiCtrlCodes` (already used for agent names in this file) before rendering. Added a regression test asserting the raw ESC bytes don't survive. - [perf] `detailedDisplay` was extracted on every successful tool call (~25K chars from core's truncation) but is consumed only by the transcript's fullDetail render for collapsible (read/search/list) tools. Gate the extraction on `isCollapsibleTool(displayName)` so edit/write/command/agent calls no longer store a large string the renderer never reads — mirrors ToolMessage's `usingDetailedDisplay` gate (which also keys off the display name). Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(tui): gate resume-path detailedDisplay on isCollapsibleTool (match live path) The resume path (resumeHistoryUtils.ts) extracted `detailedDisplay` for every successful tool call, unlike the live path in useReactToolScheduler which gates on `isCollapsibleTool(displayName)`. Since the transcript's `usingDetailedDisplay` only consumes it for collapsible (read/search/list) tools, resuming a session with many edit/write/command/agent calls stored large (~25K char) strings the renderer never reads. Apply the same gate so live and resume stay consistent, using `toolCall.name` (the display name, set from `tool.displayName`) to match the renderer's key. Updated the existing derivation tests to use a collapsible read tool (an edit tool now correctly yields undefined) and added a regression asserting a non-collapsible tool leaves detailedDisplay undefined on resume. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(tui): strip bare C0 control bytes from transcript detailedDisplay + memoize Follow-up to the ANSI-escape fix. `escapeAnsiCtrlCodes` delegates to ansi-regex, which only matches ESC-prefixed sequences, so bare C0 control bytes without an ESC prefix (BEL \x07, BS \x08, FF \x0c, SO \x0e, SI \x0f, CR, …) passed through to <Text> and could still corrupt the display or ring the bell from a malicious file's contents. Add a second pass that strips those bytes (keeping only TAB and LF, which structure multi-line output). Memoize the two-pass sanitization with useMemo keyed on detailedDisplay so the ~25K-char regex work doesn't re-run every render. Extended the ToolMessage regression test to assert bare C0 bytes are stripped alongside the ESC sequences. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * test(tui): memoize HistoryItemDisplay, add ErrorBoundary tests + TAB/LF invariant Addresses three review suggestions: - Wrap `HistoryItemDisplay` in `React.memo` so the Ctrl+O transcript (which re-renders on every scroll tick) skips re-rendering frozen-snapshot items whose props are shallowly unchanged. The transcript passes stable `item` references, so the default shallow compare is effective; harmless for the main view (items live in `<Static>` and render once). - Add ErrorBoundary.test.tsx covering the four behaviors: renders children when healthy, catches a render error into the default fallback with the message, renders a custom fallback, calls `onError` with the error + component stack, and `reset` clears the error state so the subtree recovers. - Lock the C0-strip invariant: assert TAB and LF survive in detailedDisplay (the regex intentionally skips \x09/\x0a) so a future regex change can't silently collapse multi-line/columnar output. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * refactor(tui): review cleanups — gate sanitize memo, drop dead code, add tests Addresses the latest /review suggestions: - ToolMessage: gate the `sanitizedDetailedDisplay` useMemo on `usingDetailedDisplay` so the ~25K-char escape+strip no longer runs for every collapsible tool in the main view (where the result is discarded). - TranscriptView: remove the dead `listRef` (created + passed as `ref` but never used imperatively) and the dead `onClose` prop (declared, then `void`-ed; close keys are owned entirely by AppContainer's global keypress guard). Dropped the now-unused `useRef` / `ScrollableListRef` imports and the `onClose` call-site + props. - Tests: add TranscriptView error-fallback coverage (a throwing item renders the recovery fallback, not a crash); add live-path `mapToDisplay` detailedDisplay extraction coverage (collapsible → extracted, non-collapsible → undefined); add Ctrl+O to the transcript close-keys it.each (the toggle key was the only close key untested). Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * test(tui): remove orphaned no-op CompactModeProvider stubs This PR deleted the CompactModeContext, leaving identical no-op `CompactModeProvider` passthrough stubs (with an ignored `value` prop) in ToolGroupMessage.test.tsx, ToolMessage.test.tsx and MainContent.test.tsx, each still wrapping every render. Remove the stubs and unwrap the renders; drop the now-meaningless `compactMode` params/args from the local render helpers. Behavior-preserving (the stubs rendered children verbatim) — all three suites still pass. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(tui): strip bidi overrides, sanitize error fallbacks, share filters Latest /review round: - [Critical] Strip Unicode bidirectional override / isolate chars (Trojan Source, CVE-2021-42572) from transcript `detailedDisplay` — a third sanitize pass after ANSI + C0 stripping, mirroring the repo's existing BIDI_CONTROL_RE. Regression test added. - Sanitize `error.message` with `escapeAnsiCtrlCodes` in both the ErrorBoundary default fallback and the TranscriptView custom fallback (defense-in-depth against control codes in a crafted error message). - Ctrl+O while the ThinkingViewer is open now swaps to the transcript (falls through to openTranscript, which clears the viewer) instead of being silently swallowed. - Extract the shared `isHistoryItemVisibleAfterRestore` predicate into types.ts and use it from both MainContent (main view) and AppContainer (transcript freeze), so the two surfaces can't diverge on which collapse-on-resume items are hidden. - Tests: use the exported `TOOL_SUCCEEDED_OUTPUT` constant instead of the hardcoded literal in generateContentResponseUtilities.test.ts. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(tui): harden compaction guard to always clear detailedDisplay The compaction cleanup only cleared `detailedDisplay` inside the `resultDisplay != null` branch (both the group-level trigger, the group-count pass, and the per-tool clear). A tool carrying only `detailedDisplay` (no resultDisplay) would skip compaction and leave the raw transcript detail intact — a latent privacy leak if the two fields ever decouple. Widen all three checks to also match `detailedDisplay != null` so the memory/privacy safeguard is robust. Added a defensive regression test. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(core): sanitize mime/uri in getToolResponseDisplayText media placeholders The `<media: …>` placeholder interpolated `inlineData.mimeType` / `fileData.mimeType` / `fileData.fileUri` from tool responses verbatim. A crafted response could embed control characters or angle brackets to inject terminal codes or forge/mangle the placeholder markup. Add a `sanitizeMediaLabel` helper that strips C0/C1 control bytes and `<`/`>` before interpolation, falling back to the default label when emptied. Regression test added. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * test(tui): report a TTY stdout in BaseSelectionList mouse integration test The `stdout.isTTY` gate added to `useMouseEvents` (stops SGR mouse escapes leaking into piped output) left QwenLM#6011's BaseSelectionList mouse test — which renders via ink-testing-library where the hook-provided stdout reads as non-TTY — with the mouse layer disabled, so the any-event enable escape was never written. Mock ink's `useStdout` to report `isTTY: true` with a capturing write spy (matching useMouseEvents.test.tsx / ScrollableList.test .tsx), and assert the `?1003h` enable via that spy while items still render through ink's own stdout. Both cases pass. Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * docs(core): fix JSDoc placement + note ErrorBoundary fallback is un-translated Two small review nits: - getToolResponseDisplayText's JSDoc had ended up above sanitizeMediaLabel (added last commit), making it read as that helper's docs. Reorder so sanitizeMediaLabel + its own JSDoc come first and each doc sits directly above its function. - Document why the ErrorBoundary default fallback's title is intentionally a plain English string (last-resort message for callers with no `fallback`; renders mid-crash, so it avoids pulling in the i18n layer — the transcript passes its own localized fallback anyway). Generated with AI Co-authored-by: Qwen-Coder <qwen-coder@alibabacloud.com> * fix(tui): share terminal-sanitize pipeline; guard AlternateScreen writes - Extract the three-pass sanitizer (ANSI escape + bare-C0 strip + bidi strip) into `sanitizeTerminalText` in textUtils.ts as the single source of truth, and use it at all raw-text render sites: ToolMessage's `detailedDisplay`, and the TranscriptView + ErrorBoundary error-message fallbacks (previously those only escaped ANSI, missing C0/bidi — the boundary catches errors from the fullDetail path that processes raw tool output, so a crafted item shape could carry unsanitized bytes into error.message). Removes the duplicated regex consts from ToolMessage. - AlternateScreen: wrap the alt-screen escape writes (and the exit/cleanup writes) in try/catch so a synchronous stdout error (EPIPE on terminal close, EAGAIN under backpressure) can't propagate uncaught from the effect and crash the app or corrupt the terminal.

…wenLM#8353) * fix(cli): let ESC cancel ongoing work before popping queued messages When the agent is actively responding (streamingState === Responding), InputPrompt's ESC handler consumed the key before AppContainer's global cancel-work handler could fire. Users had to press ESC 3 times (pop queue, clear input, cancel work) to stop the agent. Skip the pop-queue-into-input and double-ESC-clear logic when the agent is responding, returning false so the key propagates to the global handler which cancels the ongoing request. The up-arrow key still pops queued messages into the input at any time. Fixes QwenLM#8201 * fix: narrow ESC fall-through to empty buffer + add regression tests Address wenshao's review on QwenLM#8353: - Gate the return false on buffer.text === '' to prevent BaseTextInput's default ESC from silently wiping typed input without double-press confirmation - Add resetEscapeState() before return false to clear any pending escPressCount/escape-prompt timer - Add two regression tests with streamingState: StreamingState.Responding: 1. queue non-empty + ESC -> popAllQueuedMessages NOT called 2. buffer has text + single ESC -> buffer NOT cleared * fix: correct ESC comment to reflect KeypressContext broadcast model Address bot suggestion: the comment claimed returning true 'consumed the key before the global cancel-work handler could fire', but KeypressContext broadcasts to all handlers regardless of return value. The real mechanism is that popQueueIntoInput() fills the shared buffer, steering AppContainer's handler into its 'input has content -> double-press to clear' branch instead of the cancel-work branch. * fix: correct comment to accurately describe return false -> BaseTextInput fall-through Bot suggestion: the comment said returning false 'avoids' BaseTextInput's wipe, but return false actually *enables* it (BaseTextInput only short-circuits on truthy returns). The buffer is safe because the buffer.text === '' gate makes the wipe a no-op, not because return false prevents it. Reworded to make this explicit and warn against relaxing the gate. * test(ui): add positive AppContainer ESC cancel regression test The PR's Responding guards were pinned only by InputPrompt-side tests (queue not popped; non-empty buffer preserved). Add the positive case the review asked for: while Responding with an empty buffer and queued follow-ups, a single Esc reaches the global handler's cancel-work branch (cancelOngoingRequest called once) and the queue is not consumed. QwenLM#8201 * test(ui): clarify ESC cancel test scope vs end-to-end drain The positive ESC cancel test asserts popAllMessages is not called, but the comment framed it as 'must not consume the queue' end-to-end. In production that exact cancel path DOES drain the queue back into the buffer via the cancel handler (cancelOngoingRequest -> onCancelSubmit -> popAllMessages), under the 'never silently drop queued work' invariant. The assertion only holds because cancelOngoingRequest is replaced by a spy here, severing that hop. Reword the comment to describe the real contract: the global keypress handler itself doesn't pop the queue (InputPrompt owns that and skips it while Responding; QwenLM#8201), while the end-to-end drain is a separate hop severed by the spy. Addresses the review finding on AppContainer.test.tsx:2405. * test(ui): pin ESC return-false branch and dedupe getGlobalKeypress Address two review suggestions on the ESC cancel tests: - The `return false` branch in InputPrompt.tsx (Responding + empty buffer + empty queue -> defer to AppContainer's cancel-work branch) had no test coverage: reverting it left all 334 tests green. Add an InputPrompt test that pins it (no queue pop, no buffer mutation). - The AppContainer cancel test inlined a byte-identical copy of the getGlobalKeypress() helper that already existed ~2600 lines down in the Ctrl+O describe block. Hoist the helper to the outer describe so both blocks share one definition of the fragile toString() discovery idiom. * test(ui): escape raw ESC byte in cancel test fixture Per review (R4-1): the sequence literal embedded a raw 0x1B control byte that renders as an empty string in diffs and truncates grep output, so the fixture was unreadable. Use the escaped form matching the sibling vim-INSERT fixture on the line above. * test(ui): assert buffer stays empty on ESC cancel + fix test comment Per review (R5-1/R5-2): the flagship QwenLM#8201 test asserted only the mechanism (popAllQueuedMessages not called), not the effect (buffer stays empty so AppContainer takes its cancel branch). Add the buffer assertion. Also correct the return-false test comment: deleting that branch leaves the test green (KeypressContext.broadcast ignores return values, BaseTextInput's clear is a no-op on empty buffer), so the test pins the no-side-effect contract, not the branch itself. * test(ui): cover queue+text ESC and double-ESC-clear while responding Per review (R6-1/R6-2): the pop-skip guard was pinned only for the empty-buffer case, and the double-press clear contract had no test under Responding. Add: - non-empty queue AND typed text: ESC does not pop the queue and preserves the buffer (pins the guard regardless of buffer content). - double-ESC while Responding: first ESC preserves typed text, second clears it (pins the double-press contract this diff preserves). * test(ui): dedupe escKey fixture and tighten double-ESC timing Per review (R7-1/R7-2): the double-ESC test spaced presses with the default 150ms wait (~30% of the 500ms window); use 50ms to match the sibling double-ESC test. Hoist the escKey fixture to the Cancel Handler describe scope so both tests share one definition (matching the getGlobalKeypress hoist this PR already did). * test(ui): add missing removeGoalTurns to cancel-handler queue mock Per review: the cancel-handler test's useMessageQueue mock omitted removeGoalTurns, a required member that every other queue-mock override in this file includes. The real cancel handler calls removeGoalTurns() before popAllMessages(); the test passed only because cancelOngoingRequest was a spy severing that hop. * test(ui): reuse getGlobalKeypress in vim-INSERT cancel test Per review (R9-1): the vim-INSERT test still inlined a handler-discovery loop matching on 'handleExit', duplicating the hoisted getGlobalKeypress helper (matching TOGGLE_THINKING_EXPANDED). Both tokens occur in the same handleGlobalKeypress closure, so the two idioms can only drift. Reuse the shared helper. * test+docs(ui): escape ESC byte in shared fixture and document Responding Esc Per review (R10-1/R10-2): the shared escKey fixture embedded a raw 0x1B control byte (invisible in diffs, truncates grep). Use the escaped form. Also update keyboard-shortcuts.md: Esc now cancels the ongoing request while the agent is responding instead of moving queued messages back into the input. * docs(ui): correct ESC/Up-Arrow queue-pop description to match code Per review (R11-1): the previous wording said queue pop happens only when idle, but Up Arrow pops in any state (no streamingState guard) and Esc pops whenever not actively responding (including WaitingForConfirmation). Reword to match the code, and note that the responding-cancel only fires when the input is empty. * refactor(ui): drop dead Responding ESC guard per maintainer review wenshao's mutation test showed guard #2 (Responding + empty buffer -> return false) is dead code: with it gone, control falls to the escPressCount===0 branch which returns true on an empty buffer, and KeypressContext.broadcast ignores handler return values anyway - AppContainer's own cancel branch acts on the empty buffer either way. Remove it, fold the subscription-ordering invariants it relied on into guard #1's comment, and document that only Responding is gated (do not broaden to !== Idle or ESC becomes a no-op during a tool confirmation). Also tighten the docs wording: cancelled queued messages are moved back into the input, not preserved. QwenLM#8201 * docs(ui): correct four review comments in ESC cancel path Round-13 review (no blockers) flagged comment inaccuracies that could misdirect future debugging: - R13-1: the invariant comment pointed at an integration test that does not exist - note the harnesses mock each other's side instead. - R13-2: the regression-test comment still said the branch returns false and that AppContainer acts on return values; it returns true and broadcast ignores return values. - R13-4: the docs row claimed Up Arrow/Esc pop in any state, but during WaitingForConfirmation Composer unmounts InputPrompt (isInputActive admits only Idle/Responding), so neither key pops. - R13-5: the guard comment warned against broadening to !== Idle as if WFC ran this branch; it never does because the component is unmounted. No behavior change. QwenLM#8201 * docs(ui): correct subscription-order and double-ESC-cancel comments Round-14 review: the invariant comment overstated subscription order as load-bearing - the Responding pop guard skips the pop in either order, and InputPrompt re-subscribes after AppContainer on any remount (e.g. a tool-confirmation round trip), so only the buffer.text-liveness invariant matters. And the double-ESC clear comment now notes it composes with AppContainer's cancel on the same keypress in the initial order but lands on the next press after a remount. No behavior change.

…lback (R4-4) `handleImMessage` leaves a replayed document notification UNMARKED on purpose, for history polling to pick up, and pulls `notificationWatermark` back to the replay's `eventTime` so a future window can reach it. `pollOnce` then wrote `checkpoint.endTime` over that watermark unconditionally when its own window finished — and `checkpoint.endTime` is always past the replay's `eventTime`. The race is not hairline: `runLoop` polls immediately on connect and the IM subscriptions start before the poll loop, so a startup replay arrives precisely while poll #1's `listDirectMessages` is awaiting. One clobber puts the parked replay outside every window the watermark will ever produce — no turn, no log, no error, and it survives restarts because `saveCursor()` persists it. `pollOnce` now records whether the watermark was pulled back while its direct-message fetch was in flight, and on that path drops the window instead of finishing it: neither the advance nor the paginated checkpoint resume is safe, because the checkpoint was itself derived from the pre-pullback watermark. The next poll re-derives a window from the pulled-back value. Test: `keeps the stale-replay pullback when a poll was already in flight` emits the replay from inside `listDirectMessages`. Mutation-checked — forcing the guard false reddens it with `inbound` empty, matching the reviewer's witness (`dispatched = 0`). It also asserts the second query window opens at or before the replay's `eventTime`, so a fake that ignored its window could not certify it.

…10124) * refactor(core,cli): rename Gemini residue in memory/spinner/leaf ids PR 1 of QwenLM#4063 item 6 (de-Google naming). Renames three independent families plus the leaf LLM types: - Memory filename: GeminiMd* -> Memory* (project memory file, not an LLM client) - UI spinners: GeminiRespondingSpinner/GeminiSpinner -> RespondingSpinner/Spinner - Leaf types: GeminiCodeRequest/GeminiChatSendOptions/GeminiErrorEventValue/GeminiFinishedEventValue -> Llm* - geminiRequest.ts -> llm-request.ts (and its collocated test) No behavior change. Renamed symbols typecheck clean in core+cli; eslint clean on renamed files. Refs QwenLM#4063 * fix(cli): resolve rename build failure * docs(serve): fix memory filename references * test(cli): pin primary workspace QWEN.md init fallback Assert that the primary daemon workspace service receives the hard-coded 'QWEN.md' context filename when boot settings carry no context.fileName. Previously only the secondary workspace's explicit SECONDARY.md resolution was asserted, so swapping the fallback literal at the createDaemonWorkspaceService call site survived the suite. * refactor(core,cli): finish Gemini residue rename in memoryDiscovery Complete the rename flagged in review: GeminiFileContent -> MemoryFileContent (module-local interface), includeDirectoriesToReadGemini -> includeDirectoriesToReadMemory (parameter only; all call sites are positional, zero cross-package impact), plus test-local variable names and the stale ORIGINAL_GEMINI_MD_FILENAME test title. * docs(design): route loadHierarchicalGeminiMemory to Memory naming Per exception #1 the Llm prefix is reserved for the generic LLM-client surface; the symbol is a memory-file loader (thin wrapper around core's loadServerHierarchicalMemory), so the PR-2 symbol map targets loadHierarchicalMemory instead of loadHierarchicalLlmMemory. Doc-only: the code symbol is not renamed by this PR. * docs(cli): narrow extractContextFilename fallback description The undefined fallback first inherits the primary workspace's configured context.fileName snapshot (contextFilenameForInit) at the secondary startup and dynamically added workspace call sites, before the hard-coded QWEN.md. Describe the actual chain instead of the hard-coded default only. Comment-only: the inheritance behavior predates this PR and is unchanged. * refactor(cli): rename loadHierarchicalGeminiMemory to loadHierarchicalMemory The design doc's symbol map routes the memory loader to loadHierarchicalMemory (memory family, exception #1), but no phasing bullet performed the rename and a prior round left the mixed signature. Complete the rename across the definition (config.ts), the AppContainer call site, and the AppContainer test mocks, and update the design doc's exception #1, symbol map, and PR-1 phasing bullet so the map row is no longer orphaned. * fix(core): preserve Gemini rename compatibility * docs(core): extend Gemini deprecation window * refactor(core,cli): rename Gemini LLM identifiers * fix(core): retain Gemini content generator aliases * docs(core): document legacy content generator paths * ci: trigger checks after retargeting to main * test(cli): update renamed LLM expectations --------- Co-authored-by: qwen-code-dev-bot <qwen-code-dev@service.alibaba.com>
