Bound the final-transcription phase with a deadline (resubmission of #1246) - #1301
Conversation
… engine is slow A slow-but-alive primary engine previously had no remedy: automatic recovery fallback only fires on a hard error, so a degraded provider meant waiting out the full request. This adds an opt-in hedge to the Automatic Fallback feature: when the primary transcription has not answered within a configurable threshold, the same audio is dispatched to the recovery fallback engine in parallel; whichever result arrives first wins and the losing request is cancelled. - The race lives in DictationViewModel.transcribeFinalAudio via a task group; a primary failure before the hedge fires is rethrown so the existing sequential error-path fallback applies unchanged, and a primary failure after the hedge fires awaits the in-flight fallback. - Off by default; the toggle and threshold stepper sit in the Dictation Recovery settings under Automatic Fallback, gated on the same license and engine-configuration checks, with a note that a dispatched race costs one extra API call. - The primary engine call is now routed through an injectable PrimaryTranscriptionRunner (mirroring RecoveryFallbackRunner), which keeps the race deterministic under test. - New settings are included in settings backup/restore. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…shold; keep the fallback engine selection - The race no longer uses a task group, which waits for every child before its scope exits: with a losing engine that does not honour cooperative cancellation (the plugin contract does not guarantee it) the winner was delayed until the loser gave up, defeating the feature. Both requests now run as unstructured tasks under an arbiter that resumes the caller on the first decisive event, cancels both tasks, and drops whatever the loser reports later; the loser is never awaited. Outer cancellation is forwarded. Regression test uses a primary that ignores cancellation entirely and asserts the fallback result returns without waiting. - The hedge threshold is clamped to the range the UI offers (1...15 s) at every entry point - stored value, live value, and settings-backup restore, where a non-finite or out-of-range value is rejected - so a value like 1e308 can never reach the sleep conversion. - The threshold label uses locale-aware number formatting. - DictationRecoveryViewModel no longer erases the stored recovery engine when the plugin manager cannot resolve it at that instant (plugin bundles still loading after a relaunch, or a reload in flight). That reconcile runs on every plugin-manager change and was silently wiping the fallback engine, which turns the hedge off entirely; an unresolved selection already degrades safely to no fallback until the plugin is available.

A cloud transcription request that neither errors nor completes (a stalled upload, a server that accepted the audio and went silent) left the app in "Transcribing..." indefinitely; the only way out was Escape. The hedge race does not help here because both engines can hang the same way. transcribeFinalAudio now races the whole phase (primary, hedge, and the sequential fallback together) against a deadline of 60 seconds plus the recording's own length. When the deadline passes the in-flight requests are cancelled and a TranscriptionDeadlineExceeded error flows through the existing failure path, so the user sees an error and the recording is kept in Dictation Recovery instead of the app hanging. The bound is injectable for tests and scales with audio length so long recordings on slow local engines are not cut off. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
… imported recovery preferences Review follow-ups for the transcription deadline: - The deadline no longer depends on cooperative cancellation. The whole final-transcription phase runs as an unstructured task settled through a DeadlineArbiter (the same first-decisive-event design the hedge race uses): when the deadline fires the caller receives TranscriptionDeadlineExceeded at the bound, the in-flight work is cancelled (which aborts the transport for runners that honour cancellation) but never awaited, and a late result is dropped. Outer cancellation is forwarded. Regression test with runners that wait on plain dispatch timers no Task cancellation can interrupt. - Imported hedge settings now update the live configuration: SettingsBackupExporter.importBackup reports when any recovery preference was applied, and the settings view reloads DictationRecoveryViewModel.shared from UserDefaults, so the values ServiceContainer consults change without a restart. Tests cover the import notification and the reload (including clamping). Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

The error text claimed the recording was kept in Dictation Recovery, which is not true under the 'Immediately' retention policy or after a failed file move. The description now covers the timeout only; the failure path appends the recovery confirmation and the Open Recovery action itself when a file was actually preserved. Two API-path tests cover the timeout feedback with recovery disabled and with a preserved recording, using a transcription mock that hangs on a timer no cancellation can interrupt, and the dictation context harness can now inject a transcription deadline.

Verified the requested correction: timeout text no longer promises a saved recording. The API-path tests cover both disabled recovery and successful preservation with the Open Recovery action. The exact test command is now documented.
Merged current main and checked the conflict resolution: the deadline/reload changes are preserved alongside the already-merged hedge implementation. All 310 selected local tests passed with zero failures on 03de9e8. This supersedes my previous changes-requested review. Remote app, SDK, and release-build checks must finish successfully before merging.

Resubmission of #1246. Apologies for letting that one sit — the September 2 review went unanswered while I was working through the other PRs, and that's on me. GitHub does not allow reopening #1246 after its head was rebased, so this is the same change resubmitted on a corrected base with all three points from that review addressed. Fixes #1245.
Base. Updated with
mainafter #1230 merged. The hedge implementation and threshold validation are now part of the base. The remaining changes add the final-transcription deadline, accurate timeout/recovery feedback, and live reload of imported recovery preferences through both the settings UI and automation API.The bound no longer depends on cooperative cancellation.
transcribeFinalAudioruns the whole phase (primary, hedge, sequential fallback) as an unstructured task settled through a smallDeadlineArbiter, the same first-decisive-event design Add hedged transcription: race the recovery fallback when the primary engine is slow #1230 now uses for the race. When the deadline fires, the caller getsTranscriptionDeadlineExceededimmediately; the in-flight work is cancelled — which aborts the transport for runners that honour cancellation (URLSession's async APIs do) — but it is never awaited, so a runner that ignores cancellation cannot hold the phase open, and whatever it produces later is dropped. Outer cancellation is forwarded. Regression testtestTranscriptionDeadlineHoldsAgainstRunnersThatIgnoreCancellation: both runners wait on plain dispatch timers that no Task cancellation can interrupt (3 s), the deadline is 0.5 s, and the test asserts the error is returned in under 1.5 s while both runners are still hung. The earlier cooperative test is kept as well.Stacked base corrected as above; the threshold conversion in the race is now guarded by the
1...15clamp from Add hedged transcription: race the recovery fallback when the primary engine is slow #1230.Imported hedge settings update the live configuration.
SettingsBackupExporter.importBackupgained adictationRecoveryPreferencesDidChangecallback, fired when any recovery preference was applied; the settings view uses it to call the newDictationRecoveryViewModel.reloadPreferencesFromDefaults(), which re-reads engine, model, language, automatic-fallback, hedge toggle and threshold (clamped) into the already-initialized instance thatServiceContainerconsults. Tests:testImportNotifiesWhenRecoveryPreferencesWereApplied(no recovery preference → no callback; threshold or toggle → callback, value persisted) andtestReloadPreferencesFromDefaultsPicksUpImportedValues(imported values become the live ones, model survives the engine reload, an out-of-range threshold is clamped).

A cloud transcription request that neither errors nor completes (a stalled upload, a server that accepted the audio and went silent) left the app in "Transcribing..." indefinitely; the only way out was Escape. The hedge race in #1230 does not help because both engines can hang the same way.
transcribeFinalAudionow bounds the whole phase with a deadline that scales with the recording length (60 s + audio duration by default); when it fires, the recording is kept in Dictation Recovery and the user sees a timeout message instead of an open-ended spinner.🤖 Generated with Claude Code
