It does not change +physical-device privacy settings. It also rejects network clients, network/cloud +capabilities, and Network.framework linkage in iOS product sources. + +`build_ios_device.sh` reads the private `HC_EXPECTED_TEAM_ID` from +`.env.local`. It emits the signed `.app` path but does not install it. + +## Current scope + +This production target promotes the Gate K0 ownership boundary into the +repository's canonical `apps/ios/voice_input/` location. Local-first onboarding +explains privacy before permission, requests microphone access only after an +explicit tap, provides exact denial recovery, and observes the enabled keyboard +through the same-team local handoff. + +The containing app owns microphone capture and the audio file. The keyboard +remains a normal QWERTY keyboard and exchanges only bounded snapshot and command +JSON through a same-team local Keychain access group. The records use a this- +device-only protection class and never opt into iCloud synchronization. + +The containing app can import a local Model-package folder. It copies only a +bounded, link-free inventory into private storage, validates the exact package +through the linked Rust boundary, installs matching identity/version bytes +atomically, and preserves the original folder. Installed models use Data +Protection and stay outside OS backup. Files-picker imports are labeled manual; +the user explicitly selects an admitted compatible package for transcription. +The library defaults to 12 GiB and eight installed versions. These limits are +configurable policy; rejected admission leaves every installed package +unchanged. The app never implicitly evicts a model and provides explicit +removal of only its private installed copy. + +An active compatible package now drives pinned local whisper.cpp file ASR in +the containing app. The runtime revalidates selected model bytes before load, +prewarms one actor-owned context, and returns bounded Raw text with timed +segments. Neither extension links the runtime or can read model bytes. + +The app applies the shared deterministic spoken-edit and semantic-formatting +core, then commits Raw, Edited, Formatted, Style, model provenance, and copied +audio evidence to searchable local SQLite History before publishing text. +History supports retained-audio playback and configurable age, byte, and count +caps; its default 90-day, 1-GiB, 2,000-artifact policy expires audio without +deleting transcripts. History storage presets persist in a versioned local +preference. Users can pin retained successful or Recovery audio. Automatic +maintenance skips pinned audio, restores a 1 GiB basic-volume free-space +reserve, and surfaces failures without invalidating a durable capture. Future or +damaged preference state is preserved read-only instead of being overwritten. + +The keyboard cannot access the microphone or launch the containing app. A cold +capture starts from the containing app, its stateful Control Center/Lock Screen +control, the Action button, Siri, or Shortcuts. The containing app owns capture +and publishes a Live Activity with an exact stop action. System-surface stops +use Natural; in-app and keyboard stops retain their selected Style. While the +app owns capture, the keyboard can request stop, wait for a matching result, and +make one automatic insertion attempt. If UIKit cannot confirm that update, one +explicit same-process retry and one 10-minute local-only copy remain available +only while the exact result and target still match; otherwise History is the +recovery path. App and keyboard menus persist separate defaults for Natural, +Casual, Formal, Technical, and Verbatim. The keyboard freezes its selection on +the exact stop command, and a matching session can insert only once. The durable +insertion claim precedes the host-field change; after a crash, History is the +recovery source for a claimed result that did not reach the field. Physical +iPhone keyboard evidence remains required. + +After a keyboard-free capture, use History to copy or share the completed text, +or retrieve the bounded Ready result from the keyboard later. The app never +guesses a target field. On relaunch, orphaned Live Activities end and old active +state becomes Interrupted while exact partial audio remains recoverable. + +Recording and Transcribing publish local heartbeats. If the app stops responding +for three seconds, the keyboard clears its pending target, stops polling, and +shows one `Restart…` action with the app/Control Center restart steps. It never +launches the app. Delivery also requires a result sequence newer than the stop +request; the durable session receipt defeats every replay after insertion. + +Voice is available only in recognized general-text fields. Constrained, +sensitive, and unverified traits keep the keyboard usable but disable its mic. +The keyboard retains only an ephemeral session/document/change identity while +waiting; changing text, selection, or fields sends recovery to History instead +of inserting at a changed target. + +The containing app maps audio interruptions, route changes, media-service loss, +background transitions, Low Power Mode, and thermal pressure into explicit +capture decisions. Background recording continues only while its Live Activity +is owned. Capture never automatically resumes after a sensitive interruption. +Stopped audio gets a bounded background-finalization task; expiration or another +stop condition preserves the exact partial as playable Recovery History when +storage is available. On first History access after launch, only readable exact +session artifacts are adopted. Damaged, empty, unknown, and noncanonical files +remain untouched and cannot hide valid History. Recovery audio expires after 24 +hours without inventing transcript or model evidence. diff --git a/apps/ios/voice_input/VoiceInput.xcodeproj/project.pbxproj

It owns a dependency- +free retention policy using UUID bytes, Unix epoch milliseconds, immutable +candidates, typed validation failures, and ordered decisions. It imports no +Apple type and denies unsafe Rust. `Tests/cuj/voice_retention_v1.json` is read by +both Rust and Swift, proving policy parity while the shipped macOS app still +uses the Swift baseline. + +`voice_ffi` exposes synchronous `V1` retention, Model-package, and History- +archive functions. The +caller owns every input and output buffer; capacity-probe calls report required +storage without partial output. No callback, allocator, thread, runtime handle, +file, or pointer survives return. Reserved bytes and Boolean encodings fail +closed. Rust layout tests plus a real C17 consumer protect the source-controlled +header. Swift and Kotlin wrappers remain typed platform adapters and may not add +portable policy. See [decision 0035](decisions/0035_portable_voice_c_abi.md). + +`HardwareControllerVoiceFFI` is the Apple adapter. Its immutable `Sendable` +values translate paths, caller-owned buffers, fixed metadata, and typed status +codes without exposing an unsafe pointer to application code. A narrow C target +imports the source-controlled header and statically links the optimized Rust +archive. Canonical scripts build that archive first and update an ignored +digest-stamp Swift source only when its bytes change, forcing SwiftPM to relink +instead of reusing a stale executable. The packaged app has no Rust dynamic +library or non-system runtime dependency. See +[decision 0039](decisions/0039_linked_apple_voice_adapter.md). + +The iOS build produces device and simulator static archives, wraps them in one +generated XCFramework, and imports the same C module into the typed adapter. +The XCFramework is a build artifact, not a source-controlled dependency. + +`voice_models` owns bounded Model-package admission before any runtime sees +weights. It strictly decodes V1 manifests, rejects symbolic links and +undeclared or nonportable paths, streams SHA-256 over exact declared bytes, and +optionally compares an authenticated catalog manifest digest. License evidence, +capabilities, languages, runtime family, memory claims, and installed bytes +cross `voice_ffi` through caller-owned UTF-8 buffers and fixed scalar fields. +The verifier retains no pointer or file and links no inference runtime. See +[decision 0037](decisions/0037_portable_model_package_validation.md). + +`voice_archive` owns the portable History container boundary. It admits only +the exact link-free V1 inventory, enforces configurable manifest/checksum/audio +and result limits, parses canonical session/result UUIDs, streams SHA-256 over +the manifest and optional CAF, and returns fixed verified metadata. Swift and +Rust consume the same fixture; the C ABI retains no archive path or file. The +archive hashes establish internal integrity, not external authenticity.

Snapshot and single-slot command JSON is limited to +64 KiB per record, marked this-device-only, and excluded from Keychain +synchronization. Recording and Transcribing publish 500-millisecond heartbeats; +the keyboard rejects active state after three seconds. Session identity, a +strictly newer monotonic result sequence, 30-second command freshness, and a +keyboard-local insertion receipt reject stale, duplicate, and late results. The +keyboard polls Keychain only while awaiting a matching result and stops before +showing one documented restart path. Audio, models, History, logs, host +identity, and target context stay outside the handoff. + +Gate K0 established signing, extension, and lifecycle feasibility. The same +generated project now lives at `apps/ios/voice_input/` as the production iOS +target. Its onboarding policy distinguishes undetermined, denied, authorized, +keyboard-unobserved, and ready states without requesting permission at launch. +Its Model library imports one security-scoped folder, applies independent +entry/file/byte limits, rejects links, validates through the statically linked +Rust boundary, and atomically installs by identity/version. Packages use Data +Protection, remain outside backup, and retain manual-versus-pinned provenance. +The library separately defaults to 12 GiB and eight installed versions, with +both limits injected as policy. It never age-evicts Model packages. Explicit +removal revalidates and quarantines only the app-owned copy before deleting its +provenance and bytes. + +The first C4 runtime is pinned whisper.cpp file ASR. Rust revalidates the active +package and authenticated manifest immediately before resolving one model-role +payload. A Swift actor owns one prewarmed opaque C context, converts the +app-owned 16 kHz mono CAF to finite float PCM, and receives bounded UTF-8 plus +timed segments. The containing app alone links and embeds whisper.cpp; neither +extension sees runtime symbols or model paths. Stop produces real timed Raw text +or an explicit failure, never the K0 placeholder. The same platform-neutral +spoken-edit, semantic-document, renderer, Style, and retention sources used by +macOS compile into a narrow static iOS core target. The containing app applies +those deterministic stages, copies the stopped CAF into actor-owned History, +and commits a versioned SQLite payload before it publishes matching Formatted +text to the Keychain handoff. History stores immutable Raw, Edited, Formatted, +timed-segment, model, Style, digest, byte-count, and audio-expiry evidence; its +UI searches, discloses Raw/model provenance, and plays retained CAFs. Startup +reconciliation on first History access adopts only exact readable lowercase +session partial/orphan audio into typed Recovery sessions. Invalid, unknown, or +noncanonical files remain untouched and cannot block valid History. An exact +post-commit partial is removed only when its digest matches committed audio; +differing bytes recover under a new session identifier. Recovery +audio expires after 24 hours without inventing transcript stages. Data +Protection and backup exclusion apply to the owned History directory, database +family, and audio. History payload revision 3 persists `isPinned`; earlier +revisions migrate to unpinned. A versioned local preference envelope configures +age, byte, and recording-count caps, while basic volume capacity requests a +1 GiB free-space reserve. Retention runs after durable commit and on History +access; maintenance failure stays visible and retries without invalidating the +capture. Pinned and sole-Recovery audio remain protected. Model-package limits +remain a separate admission boundary and never trigger implicit eviction. +The app and keyboard retain separate surface Style defaults. A schema-revision-2 +stop command captures the keyboard's explicit Style for its exact session; the +app maps that bounded identifier exhaustively into the canonical formatter. +A bounded same-device Keychain claim is written before the first host-field +insertion and deduplicates every automatic path by session identity, including +re-published ready snapshots. If UIKit provides no text-change callback within +500 milliseconds, the keyboard offers one explicit same-process retry and one +local-only copy expiring after ten minutes. Both actions revalidate the exact +Ready result, receipt, document, and host-change revision; any mismatch or +extension restart recovers through History. The copy path is capped at 256 KiB +of UTF-8 and never reads the pasteboard. See +[decision 0040](decisions/0040_ios_keyboard_activation_and_handoff.md), +[decision 0041](decisions/0041_ios_model_package_admission.md), +[decision 0042](decisions/0042_ios_whisper_file_asr.md), +[decision 0043](decisions/0043_ios_local_formatting_and_history.md), and +[decision 0044](decisions/0044_ios_style_qualified_keyboard_delivery.md). Only +recognized general-text UIKit traits permit Voice. An ephemeral session UUID, +opaque document UUID, and text/selection revision bind delivery without +retaining target text or app identity; mismatch recovers from History. See +[decision 0045](decisions/0045_ios_host_field_and_delivery_target_safety.md). +The bounded insertion-recovery contract is in +[decision 0048](decisions/0048_ios_bounded_insertion_recovery.md). +The capture actor maps interruption, route, media-service, background, power, +and thermal signals into explicit lifecycle policy. Visible Live Activity +ownership is mandatory for background recording; stopped capture gets one +bounded background-finalization task. Expiration invalidates late output, +preserves the exact partial, and never auto-resumes. See +[decision 0046](decisions/0046_ios_capture_lifecycle_and_recovery.md). +The keyboard treats missing, future, expired, or unknown-schema active state as +stale, clears its ephemeral delivery target, and never launches the app. See +[decision 0047](decisions/0047_ios_stale_service_recovery.md). The iOS build +also runs a static local-only source and capability check. See +[decision 0049](decisions/0049_ios_offline_storage_enforcement.md). + +The WidgetKit control reads only the bounded current snapshot and uses a +`SetValueIntent`; Audio Recording start/stop intents write the same single-slot +command. Start foregrounds the containing app. Recording publishes a Live +Activity with an exact stop action, and the actor consumes stop while recording +under lock or in background.

A bounded nonblocking tee writes audio on a +utility task; successful finalization synchronizes and atomically renames the +CAF before an actor-owned system SQLite transaction stores the Voice session. +Deterministic tests cover one insertion, every final text stage, playable audio, +database reopen, typed storage unavailability, and cancellation cleanup. Timed +Raw spans, UI, retention, crash reconciliation, portable Rust, alternate ASR, +and iOS remain subsequent CUJ slices. + +M2 adds one disabled-by-default, machine-wide exact Voice chord to the existing +app. Its first key-down begins the coordinated Local AI workflow immediately; +release after a hold finishes, while two short presses latch and the next two +finish once. One Carbon owner reserves both active-Profile Binding fallbacks +and this distinct chord. Replacement and lifecycle interruption cancel Voice +ownership before registration teardown. Application preference schema 4 stores +the validated settings and migrates earlier schemas with the chord disabled. + +M3 advances application preferences to schema 5 and stores one versioned +Natural, Casual Message, Formal, Technical, or Verbatim Style. Prompt revision +5 carries Style as typed untrusted payload data and centralizes its bounded +instructions. Verbatim bypasses the model. The Swift baseline converts +validated output into evidence-backed paragraph/list blocks, renders structure +only where the captured target supports it, and stores the encoded document in +a nullable SQLite column. Earlier schema-4 preferences default to Natural and +earlier Voice databases retain their rows with no structured document. + +M4 adds a deterministic Swift spoken-edit engine before formatting. Exact +backtrack, sentence-delete, paragraph, numbered-list, and literal-escape phrases +become typed operations with source and affected-output UTF-8 evidence. One +strict replayer validates the revision and canonical trace before SQLite stores +or returns it from a nullable column. Raw is the trace source, so a Dictionary +replacement cannot synthesize a command; exact replacements run afterward to +produce Edited text. Provider failure delivers Edited text, while an empty +Edited result skips generation and insertion without discarding the session. +Ambiguous, near-match, and structurally inapplicable commands remain literal. +This amends the earlier Raw-only fallback wording: Raw remains recoverable, but +the one automatic fallback delivery uses deterministic Edited text whenever +that stage exists. + +The M5 ownership guard requires Local AI to capture an empty caret without +discarding the target's native, web, or terminal delivery route. Before every +mutation it distinguishes target-process replacement, secure-state change, +focused-element replacement, and caret movement. Any invalidation withholds +automatic insertion, retains the final text and audio, and stores a stable +typed reason beside the human-readable failure. Existing History databases add +the nullable reason column without rewriting prior sessions. Copy recovery is +available immediately. M6 adds explicit History re-delivery as a new result +rather than mutating the failed one. + +M6 adds History as the fourth destination in the existing macOS window. Each +session owns at most one CAF and an append-only graph of immutable results. +Search spans every stage; provenance and timed spans remain inspectable; and +correction, retranscription, reformatting, and explicit delayed re-delivery +append linked results. Export writes an open versioned package, pinning protects +future audio retention, and transactional deletion removes the session and its +owned audio.

Do not duplicate every combination +as E2E. + +E2E tests use accessibility identifiers and user-visible outcomes, not screen +coordinates, incidental view hierarchy, private call order, exact generative +prose, or arbitrary sleeps. Model tests use protected-token and semantic +invariants plus bounded quality/performance metrics. A behavior may change when +one focused PR updates the CUJ, test, implementation, and rationale while +preserving equivalent safety coverage. + +## macOS journeys + +### M1 — Hold to dictate and recover + +**Given** a nonsecure focused text field, microphone/Accessibility permission, a +ready local ASR provider, Natural Style, and enabled History. + +**When** the user holds the configured exact chord, says a short phrase, and +releases it. + +**Then** capture starts on key-down; provisional text may update; release stops +capture; local ASR creates timed Raw text; formatting validates; Delivered text +is inserted exactly once; and searchable History contains the audio and every +final text stage. If insertion fails, the same History item remains copyable and +retryable. + +**First tracer:** a fixture saying “send the revised plan tomorrow” produces one +session, one validated document, one delivery attempt, and one playable artifact +without any network-capable provider receiving content. + +### M2 — Latch a long prompt + +Two short chord presses within the configured interval latch one session without +delaying the first PCM frame. The user may read and speak across pauses. The next +valid double press stops once. Key repeat, an unmatched release, or a third press +does not create another session. Sleep and lost key-up terminate through the +same recovery state. + +**Current evidence:** the independent, opt-in exact Voice chord begins Local AI +Dictation on its first key-down. A long release finishes; two short presses +latch; the next two short presses finish. Pure-state, command-controller, +Carbon-boundary, preference-migration, and runtime tests cover immediate begin, +decision timeout, repeats, unmatched release, interruption, registration +conflict, and transactional replacement. Sleep and shortcut replacement cancel +before Carbon synthesizes a release. + +### M3 — Format for purpose + +The same Raw transcript can be rendered as Casual Message, Formal, Technical, +Natural, or Verbatim without retranscription. Dictated ordinal structure becomes +validated list blocks. A single-line target receives a safe plain-text rendering; +a multiline target preserves list and paragraph structure. Protected names, +commands, URLs, code tokens, and Dictionary spellings remain unchanged. + +**Current evidence:** General stores one versioned Natural, Casual Message, +Formal, Technical, or Verbatim Style. The prompt carries the selected Style as +typed data; Verbatim bypasses model preparation and generation. Validated model +text becomes evidence-backed paragraph, unordered-list, or ordered-list blocks; +Verbatim uses an opaque evidence-backed block so its text is not interpreted. +Sequential ordinal cues normalize to an ordered-list block even when a safe +model response retains them as prose. One deterministic renderer preserves +those blocks for multiline targets and +flattens them for single-line targets. SQLite stores the structured document +beside distinct Raw, Edited, Formatted, and Delivered text, and migrates M1/M2 +databases without rewriting their rows. + +### M4 — Backtrack explicitly + +“Scratch that,” “delete that sentence,” “new paragraph,” list boundaries, and +“literal” produce typed, replayable operations. An ambiguous command remains +literal text. A destructive command cannot remove stable text outside its +defined range. The Raw transcript remains inspectable. + +**Current evidence:** the deterministic Swift engine recognizes only the five +exact command phrases and one exact `literal` prefix. Operations record source +UTF-8 evidence, the affected Edited suffix, and a typed replacement. Clause and +sentence deletion stop at stable punctuation or an active list-item marker; +`new paragraph` begins the next item while a numbered list is active. Revision, +command evidence, canonical ranges, ordering, replay, and stored-result +corruption are rejected during SQLite write and read. Commands run against Raw +before Dictionary output can synthesize one. The formatter receives Edited text, provider fallback delivers +the same Edited text, and a fully scratched session retains Raw/audio evidence +without generation or insertion. Near-misses and inapplicable commands remain +literal. Deterministic engine, replay, controller, fallback, empty-result, JSON, +SQLite migration, and corruption tests cover the journey. + +### M5 — Preserve ownership when the target changes + +If focus, caret ownership, secure status, or target process changes after capture +begins, automatic insertion is withheld. Capture and local finalization finish, +History records the reason, and the user can copy or explicitly retry. The app +never submits the target or types into the replacement field. + +**Current evidence:** Local AI captures an empty selected range and preserves +the target's delivery route. Delivery rechecks process, secure status, focused +element, and expected caret before each mutation; a failed lease performs no +later mutation. The copyable Formatted/Edited result, audio, human-readable +failure, and stable typed reason remain in the stored session. Deterministic +policy, route-preservation, per-chunk writer, controller, SQLite migration, and +database-reopen tests cover this guard. M6 adds explicit re-delivery as a new +result linked to the immutable session. + +### M6 — Browse and reuse History + +The user searches Raw, Formatted, Delivered, or corrected text; opens a result; +plays from a timed span; sees source, Style, and model evidence; corrects without +mutating earlier stages; and independently retranscribes, reformats, exports, +pins, or deletes the session. Re-running a stage creates a new result linked to +the same immutable audio. + +**Current evidence:** History is a fourth native destination backed by actor- +owned SQLite. It searches every result stage, exposes provenance and bounded +timed spans, appends correction/retranscription/reformat/re-delivery results, +exports a versioned package with at most one CAF, and transactionally deletes +the session and owned audio. Re-delivery captures a fresh empty caret only after +the explicit three-second delay and records failed attempts. Migration lazily +backfills immutable baseline results without rewriting session rows. Unit, +database-reopen, corrupted-evidence, 5,000-session search, model, export, +playback, and signed packaged-UI checks cover the journey; measured warm search +p95 is 2.639 ms against the 250 ms requirement. + +### M7 — Bound storage without surprise + +When age, byte, or artifact-count quota is exceeded, cleanup skips active, pinned, +and sole recovery artifacts; removes oldest unpinned audio to the low-water mark; +retains transcript metadata; and records an Audio-expired reason. Derived cache +eviction does not change History. `Unlimited`, zero retained audio, low-disk +cleanup, corrupt sizes, and concurrent finalization have explicit results. + +Implemented evidence: the Swift baseline and dependency-free Rust planner pass +one versioned cross-language CUJ fixture; a versioned C ABI passes layout and +real-consumer checks. Separate SQLite session and retention actors share one +injected History service; preference schema 6 exposes independent macOS +controls; and database-reopen tests cover startup/post-finalization enforcement, +protected recovery audio, missing or invalid sizes, low disk, rapid shared- +service finalization, search preservation, expiration provenance, and revision-2 +export. + +### M8 — Recover from interruption and crash + +A crash or process kill during capture leaves at most one partial artifact. +Startup reconciles it into a recoverable session or removes it under the partial +retention rule. Corrupt SQLite state, an orphan audio file, full disk, audio-route +loss, and model cancellation do not block app launch or lose unrelated sessions. + +**Current evidence:** one pure planner and one startup actor reconcile exact +app-owned partial, orphan, and expiration-quarantine names before retention. +Finalization, audio import, and archive restore complete that one-time +reconciliation before creating a new finalized artifact, so concurrent +maintenance cannot recover an in-flight session. +Readable audio becomes a typed Recovery session with empty immutable evidence, +whole-file playback, and retranscription; unpinned recovered audio expires after +24 hours while its session remains. Recent unreadable audio is preserved and +stale unreferenced audio is removed. Malformed rows are isolated, a physically +corrupt SQLite family is preserved before clean storage opens, and audio +finalization failure stores completed text before surfacing its typed failure. +Deterministic planner, real CAF/SQLite, export, retention, corruption, and +presentation tests cover the journey. The current corpus passes 475 tests in 71 +suites, including a retention-first recovery ordering regression. + +### M9 — Remain local and degrade honestly + +Airplane/no-network state does not change successful local behavior. A remote- +capable provider is rejected before content transfer. When formatting is +unavailable or misses its deadline, validated Raw/Edited text is delivered under +the declared fallback policy. When ASR is unavailable, audio remains recoverable +and the target is not modified. + +**Current evidence:** every formatting adapter declares typed provider identity +and locality. The router admits only in-process and fixed numeric-loopback +providers, validates response identity, and invokes no method on a remote- +capable adapter. A production-controller acceptance test rejects such an +adapter, inserts deterministic Edited fallback once, and stores playable audio. +A separate real CAF/SQLite test fails ASR after a captured buffer, performs no +formatting or target mutation, and stores empty text stages with delivery not +attempted and playable audio. Existing deadline, provider-unavailable, +validation, late-output, and target-revalidation tests cover the other fallback +branches. The complete 475-test/71-suite host corpus passes. + +### M10 — Share one session behavior across triggers + +A physical Control, Hold chord, latch chord, and in-app record button invoke the +same Voice-session state and History contract. Trigger-specific momentary/toggle +semantics remain adapters; none changes ASR, formatting, retention, or delivery +meaning. + +**Current evidence:** the physical Action path, exact Hold/latch chord adapter, +and menu-bar record action all submit `DictationCommand` to the process-owned +Local AI dispatcher. Phase-policy tests cover Record, Stop, unavailable, and +post-capture states. Boundary tests cover Hold, double-press latch/finish, and +runtime start/suspend/resume/stop gates. The complete 480-test/72-suite host +corpus passes. + +### M11 — Prove the first portable policy boundary + +The Swift and dependency-free Rust retention planners produce the same ordered +decisions from one versioned CUJ fixture. A synchronous versioned C ABI exposes +that policy with caller-owned buffers, stable typed errors, and no retained +pointer or callback. + +**Current evidence:** Swift and Rust conformance tests share +`Tests/cuj/voice_retention_v1.json`; Rust layout and domain tests pass; and a +real C17 consumer compiles, links, and executes against the optimized static +library. Decision +[`0035`](decisions/0035_portable_voice_c_abi.md) owns the boundary. + +### M12 — Import a local recording + +**Given** History is available and the user selects a supported local audio +file within configured source-byte, decoded-byte, and duration limits. + +**When** the user chooses **Import Audio Recording**. + +**Then** the app balances access to the selected file, runs local ASR and the +selected Style, streams the recording into one app-owned CAF, and stores a +searchable session with typed imported-audio provenance. It never changes or +deletes the selected file and never inserts text automatically. Formatting +failure stores the Raw transcript fallback; ASR failure stores replayable audio +with empty text for explicit retranscription. Cancellation, unsupported audio, +corruption, or a breached limit creates no History row or owned artifact. + +**Current evidence:** the macOS defaults cap source and decoded audio at 2 GiB +and duration at 12 hours before model work. Actor-owned tests cover the real +streaming CAF/SQLite path, source preservation, Raw/Formatted provenance, +search selection, source/duration/decoded-size rejection, cancellation, +formatting fallback, ASR fallback, and legacy JSON/database defaults. Portable +archive export and restore are owned by M14. +Decision [`0036`](decisions/0036_imported_voice_audio.md) owns the boundary. + +### M13 — Admit only verifiable Model packages + +**Given** a Model package in a private staging directory and configurable +manifest-byte, installed-byte, and file-count limits. + +**When** a platform adapter asks the portable engine to validate it. + +**Then** V1 accepts only typed, stage-compatible metadata; mandatory license +evidence; portable canonical paths; a complete link-free declared inventory; +exact file sizes and SHA-256 digests; and, for an approved download, the +out-of-band expected manifest digest. It returns the exact verified identity, +capabilities, resource metadata, byte count, and manifest digest without +retaining caller memory or files. A manual package without an expected digest +is internally verified but not publisher-authenticated. + +**Current evidence:** one shared package fixture passes the Rust verifier and a +linked optimized C17 consumer. Rust and ABI tests cover buffer negotiation, +layout, malformed UTF-8, optional manifest pinning, payload tampering, +undeclared files, traversal/nonportable paths, duplicates, stage mismatch, +case-insensitive language aliases, independent limits, empty payloads, and +symbolic links. Decision +[`0037`](decisions/0037_portable_model_package_validation.md) owns the boundary. + +### M14 — Move one Voice session without losing evidence + +**Given** a user-selected V1 `.voice_history` archive, configurable byte/result +limits, and no network connectivity. + +**When** the user chooses **Import → Voice History Archive**. + +**Then** the app snapshots and verifies the exact bounded manifest, checksums, +optional CAF, session identity, and immutable result graph before copying audio +into app-owned storage and atomically restoring History. Restore never delivers +text. Reimporting identical evidence is a no-op; a UUID collision with different +evidence, tampering, undeclared entry, link, unsupported schema, or breached +limit creates no row or owned artifact. The final revision 4 macOS archive +migrates during import; all new exports use portable V1. + +**Current evidence:** Swift exports and imports the shared V1 fixture and a real +CAF/SQLite round trip. The production importer invokes the statically linked +Rust verifier on its private snapshot, compares fixed identity metadata, then +restores through Swift. Focused suites cover legacy migration, idempotence, +conflict, tampering, inventory, limits, custody, typed Swift/C translation, and +an optimized C17 consumer. Decision +[`0038`](decisions/0038_portable_voice_history_archives.md) owns the boundary. + +## iOS journeys + +### I1 — Onboard locally + +The containing app explains local processing and History retention, requests +microphone permission, validates an installed/imported Model package, guides the +user through adding the custom keyboard, and explains Full Access only when +needed for same-team local handoff. Denial leaves a usable app/keyboard +with exact recovery instructions. No permission prompt originates in the +keyboard extension. + +**Current evidence:** the production `apps/ios/voice_input/` target explains +local-only processing before permission, never prompts at cold launch, models +undetermined/denied/authorized microphone recovery as pure policy, and guides +the exact keyboard setup path. The keyboard writes a bounded this-device-only +presence marker only after Full Access exists; the app uses it to confirm local +handoff. The app also imports a folder under security-scoped access, bounds and +copies it into private storage, invokes the linked Rust validator, preserves +language and provenance metadata, cleans failed staging, and lists a valid +manual package without claiming runtime readiness. Focused tests execute the +real iOS Rust symbol and cover limits, links, tampering, identity conflicts, +idempotence, corrupt records, configured library byte/version caps, explicit +removal, and user-visible import availability. The default library cap is 12 +GiB or eight installed versions; neither limit silently evicts a package. + +### I2 — Dictate from a warm custom keyboard + +**Given** the custom keyboard is visible in an editable nonsecure field and the +containing app already owns a confirmed capture. + +**When** the user speaks and taps the keyboard mic to stop. + +**Then** the keyboard reflects only confirmed Capture-owner state; the containing +app records and runs local ASR/formatting; the keyboard requests one matching +stop and reflects bounded status; final text is inserted once through +`textDocumentProxy`; and the containing app stores History. No audio is captured +by the extension. + +**Current C4 evidence:** the containing app can persist one compatible active +ASR package, prewarm a pinned whisper.cpp context, revalidate all selected bytes +through Rust immediately before use, and convert its CAF to timed Raw text. One +shared deterministic engine applies typed spoken edits and validated semantic +paragraph/list blocks while preserving Raw. The containing app commits Raw, +Edited, Formatted, timed segments, Style, model provenance, digest-verified CAF, +and retention metadata to searchable local History before publishing +keyboard-ready text. History reload, escaped search, playback, age/byte/count +expiry, transcript preservation, and partial/orphan cleanup pass real +SQLite/filesystem tests. Wrong runtimes, missing selection, changed bytes, +bounded-output failures, and unavailable History remain explicit and do not +invent or deliver text. A native C integration test crosses the production +framework with pinned model/audio and enforces a permissive RTF gate. App and +keyboard expose separate persisted surface defaults for all five Styles. The +schema-V2 stop command freezes one explicit Style for the matching session, +real-Keychain tests cross recording/stop/ready, and insertion receipts reject a +re-published result by session identity. The keyboard persists its claim before +host-field insertion, so a crash can omit delivery but cannot replay it; History +remains available for recovery. Physical signed-device keyboard evidence +remains required before I2 is accepted. + +**Gate K0 evidence:** a signed app, keyboard, and Control Center extension share +only bounded this-device-only Keychain records. The containing app records a real +16-kHz mono CAF; the enabled keyboard types in Messages, requests a result, and +inserts the matching result once. Policy, persistence, latency, capture, and UI +tests cover the deterministic handoff behavior. + +### I3 — Start when the containing app is cold or suspended + +Apple does not permit a keyboard extension to launch its containing app, and a +custom keyboard has no microphone access even with Full Access. The keyboard mic +therefore never claims to start a cold capture. It presents one accurate action: +start Voice from the containing app, its Control Center control, or another +approved `AudioRecordingIntent`, then return to the field. The containing app +confirms capture and publishes a Live Activity before background continuation. + +Gate K0 confirms the documented ownership and handoff design in the simulator +and a correctly entitled generic-device build. The paired physical iPhone is +reachable, but installation remains required production evidence because its +free provisioning profile already contains three unrelated development apps. +No existing app is removed automatically. This does not block independent C4 +implementation. Decision +[`0040`](decisions/0040_ios_keyboard_activation_and_handoff.md) owns the boundary. + +### I4 — Type without Full Access + +Without Full Access, QWERTY typing, deletion, shift, return, space, and the globe +key remain functional. Mic is visibly unavailable with concise setup guidance. +No text, audio, or model operation crosses the unavailable shared-Keychain +boundary. + +### I5 — Respect unsupported fields + +Secure fields receive the system keyboard. Phone-pad, numeric, one-time-code, +banking, managed-device, and custom host fields follow declared capabilities. +The keyboard never starts capture where insertion or privacy cannot be assured; +it reports unsupported state without retaining target context. + +**Current evidence:** iOS itself replaces the extension for secure and phone-pad +fields and permits hosts to reject custom keyboards. If the extension is +present, a typed UIKit boundary allows only recognized general-text traits; +numeric, credential, one-time-code, payment, sensitive-identifier, and unknown +custom traits keep typing available while disabling Voice. Unsupported controls +do not read shared capture state. Decision +[`0045`](decisions/0045_ios_host_field_and_delivery_target_safety.md) owns the +boundary. Physical-iPhone host-field evidence remains required. + +### I6 — Choose a Style without target identity + +The keyboard exposes a compact Style selector and remembers the explicit +keyboard/surface default. It does not infer the host application's identity. +Casual, Formal, Technical, Natural, and Verbatim outputs pass the same shared +formatting fixtures as macOS. + +**Current evidence:** both surfaces persist only a validated stable identifier. +The keyboard displays a compact menu without widening its extension boundary, +and the containing app exhaustively maps every identifier to the canonical +shared `VoiceStyle`. The exact stop command, History record, and rendered result +retain the selected Style; later preference changes cannot alter the in-flight +session. Decision +[`0044`](decisions/0044_ios_style_qualified_keyboard_delivery.md) owns the +boundary. + +### I7 — Survive interruption and background transitions + +Incoming calls, Siri, audio-route changes, lock, background expiration, low power, +thermal pressure, and another app taking the microphone produce explicit state. +Live Activity/system recording indication matches Capture ownership. A partial +session remains recoverable; automatic resume never occurs after privacy- +sensitive interruptions without an approved rule. + +**Current evidence:** the containing-app actor owns recorder, audio session, +Live Activity, heartbeat, and bounded background-finalization task. Exhaustive +notification mapping distinguishes route swaps from category/override changes; +policy stops calls/Siri-class interruptions, media-service loss, missing +background ownership, critical thermal pressure, and background expiration. +Low Power Mode and serious thermal pressure continue with explicit advisories. +Interruption commits typed Recovery History before ownership release when +storage is available; first History access adopts exact readable partial/orphan +audio, preserves damaged or unknown files, migrates revision 1, and expires the +sole recovery artifact after 24 hours. No path automatically resumes. Signed +physical-iPhone lifecycle evidence remains open under the free-profile limit. +Decision +[`0046`](decisions/0046_ios_capture_lifecycle_and_recovery.md) owns the boundary. + +### I8 — Detect a stale service + +If the containing app is killed, upgraded, or no longer publishing a valid +heartbeat, the keyboard stops showing active state, never queues unbounded audio +commands, and offers one restart action. Duplicate or late shared-Keychain messages +cannot insert text twice or revive a completed session. + +**Current evidence:** Recording and Transcribing publish 500-millisecond +heartbeats, and the keyboard expires active state after three seconds. It polls +only after one exact stop, then clears its ephemeral target, stops polling, and +shows one `Restart…` action with the approved app/Control Center instructions. +Missing, future, expired, and unknown-schema heartbeats fail closed. Ready must +carry a strictly newer sequence than the stop-triggering snapshot, while a +durable same-session insertion receipt dominates every replayed phase. The +app alone consumes the single command slot and rejects commands older than 30 +seconds. Pure +policy, blocked-finalization actor, and real-Keychain tests cover the journey; +physical kill/suspension/upgrade evidence remains open. Decision +[`0047`](decisions/0047_ios_stale_service_recovery.md) owns the boundary. + +### I9 — Recover failed insertion + +If the host field disappears, rejects insertion, or changes during finalization, +the transcript remains in containing-app History. The keyboard offers bounded +retry/copy behavior only for the same confirmed session and target state. A late +completion from an earlier session never overwrites a newer field. + +**Current evidence:** writing a keyboard stop captures only the session UUID, +UIKit's opaque document UUID, and an in-memory revision advanced by every text +or selection callback. All must still match before the durable insertion claim +and first automatic attempt. If no text-change callback arrives within 500 +milliseconds, `Recover…` offers one explicit same-process retry and one local- +only copy capped at 256 KiB and expiring after ten minutes. Every action +revalidates Full Access, field eligibility, exact Ready session/sequence/text, +durable receipt, document, and revision. Text change confirms delivery; +selection, field, session, result, receipt, or extension-process change directs +recovery to containing-app History. History also exposes bounded copy. No path +retains target text or host identity, and no automatic path retries. Pure policy +tests cover exact matches, every mismatch class, retry exhaustion, copy bounds, +and expiry. Physical host rejection/callback evidence remains open. Decision +[`0048`](decisions/0048_ios_bounded_insertion_recovery.md) owns the boundary. + +### I10 — Remain offline and within storage limits + +Airplane mode completes keyboard and in-app capture with local models. iOS +applies its age/byte quota, pinning, partial recovery, Data Protection, and low- +disk rules without blocking capture. Installed active models are not silently +evicted as History cache. The Model library separately rejects admission at its +configured byte or installed-version cap and permits explicit package removal. + +**Current evidence:** schema-revision-3 History persists pin state and migrates +older rows unpinned. Versioned local preferences expose age, byte, and recording +presets; invalid or future state is preserved read-only. Real SQLite/filesystem +tests cover protected Recovery audio, low-disk expiry, transcript preservation, +post-commit inspection failure, Data Protection where CoreSimulator exposes it, +and backup exclusion. Model tests prove rejected admission does not evict an +installed package. `scripts/check_ios_local_only.sh` rejects network clients, +linkage, and cloud/network capabilities. Physical airplane-mode evidence remains +part of final signed-iPhone verification. Decision +[`0049`](decisions/0049_ios_offline_storage_enforcement.md) owns I10. + +### I11 — Capture without an active keyboard + +An approved App Intent, Action button, Control Center control, Siri phrase, or +in-app button starts a visibly owned Voice session. Lock/background behavior +uses the required Live Activity and finishes into History. Delivery is explicit +copy/share or a later keyboard retrieval; it never guesses a target field. + +**Current evidence:** one stateful WidgetKit control uses a current Recording +heartbeat for Control Center, Lock Screen, and Action button state. Audio +Recording start, exact stop, and toggle intents share only the bounded Keychain +command slot; Siri and Shortcuts expose named start/stop actions. The Live +Activity provides a stop button. System stops use Natural, while app and +keyboard stops preserve their own explicit Style. Relaunch without actor-owned +capture ends orphaned Live Activities, publishes Interrupted, and leaves the +exact partial for History adoption. Completed History exposes copy and share, +and no system path stores or infers a target. Pure command tests, actor tests, +generated App Intents metadata, and simulator UI cover the source contract. +Physical Lock Screen, Action button, Siri, and locked-stop evidence remains +signed-iPhone work.

identified earlier range. | +| Raw transcript | Final ASR text before spoken-edit commands or formatting. | +| Edited transcript | Raw transcript after deterministic spoken-edit commands. | +|

History +should feel like a quiet tape archive: typography, spacing, waveform, and +playback position provide hierarchy; color remains reserved for recording, +attention, and failure. + +### macOS + +Hardware Controller stays quiet in the menu bar. A configured exact chord works +without a physical Device: + +- Hold begins on key-down and finishes on key-up. +- Two short presses within a measured interval latch capture; the next two + short presses finish it. +- Capture begins on the first key-down. A long hold never waits for the + double-press interval. +- Repeats, lost key-up, sleep, permission loss, process termination, and target + replacement end ownership through the same idempotent state machine. + +The menu-bar **Record Voice** action starts or finishes that same process-owned +session without opening the main window or replacing the external text target. +Controls, chord interpretation, and the menu action remain input adapters; none +owns ASR, formatting, History, retention, or delivery. + +The HUD shows capture state and provisional text. It does not become a permanent +floating widget, follow the pointer, or submit the target. + +The existing window gains a Voice workspace: + +1. History lists sessions by time, duration, source app, Style, and outcome. +2. Session detail synchronizes playback with Raw, Edited, Formatted, Delivered, + and user-corrected text. +3. Explicit actions copy, reformat, retranscribe, export, pin, or delete. +4. Settings expose Models, Dictionary, Styles, Capture, Storage, Privacy, and + Control/keyboard trigger bindings. + +### iOS containing app and keyboard + +The iOS product includes a full custom keyboard with a mic button. That is a +required experience, not a later optional study. The architecture must respect +the extension boundary: + +- Apple does not give a custom keyboard extension microphone access, including + with Full Access. The containing app owns AVAudioSession, audio capture, local + ASR, formatting, History, and model packages. +- The keyboard owns QWERTY input, globe/next-keyboard behavior, mic/status/stop, + Style selection, recovery actions, and final insertion through + `textDocumentProxy`. +- A same-team Keychain access group carries bounded commands, session state, and + final output with this-device-only protection and cloud synchronization off. + No audio, model, History database, or target context enters that channel. +- Full Access enables the local Keychain handoff. Without it, the keyboard + remains a functional QWERTY keyboard and explains why voice input is disabled. +- The main app requests microphone permission, installs or imports models, + manages History, and starts any background-capable Voice session. The + extension never attempts to request microphone permission. + +The supported warm CUJ begins after the containing app has confirmed Capture +ownership. The keyboard mic requests stop, waits for the same session to become +ready, and makes one automatic insertion attempt at the current cursor. Tapping +mic while idle provides concise instructions instead of displaying false +recording state. + +Recording and Transcribing publish bounded heartbeats. After three seconds +without a valid pulse, the keyboard clears its target, stops polling, and shows +one `Restart…` action that explains the approved app or Control Center path. +The action never launches the app. A result must be newer than the snapshot that +caused the stop, and a durable same-session receipt defeats every replay. +If UIKit does not confirm a field update within 500 milliseconds, one +`Recover…` menu offers a single explicit same-process retry or local-only copy. +Every action revalidates the exact result, receipt, document, and host-change +revision. Copy is capped at 256 KiB of UTF-8 and expires after ten minutes; +target ambiguity and extension restart use containing-app History. + +Gate K0 confirms that a keyboard cannot access the microphone or launch its +containing app under documented App Review rules. Cold capture starts through +the containing app, Control Center, Siri, Action button, or another approved +`AudioRecordingIntent`. Intent-started recording publishes the required Live +Activity; the user then returns to the target app manually. Proprietary behavior +is UX evidence, not authorization for an undocumented activation mechanism. + +The keyboard cannot reliably identify the host application. Styles therefore +resolve from explicit keyboard selection and device/surface defaults, not an +assumed target bundle identity. + +### Platform priority and line of sight + +| Platform | Program position | Architectural requirement | +| --- | --- | --- | +| macOS | Active roadmap | Voice writing and History inside the existing Hardware Controller app. | +| iOS | Active roadmap | Containing app, custom keyboard, local inference, insertion, and History. | +| Android | Line of sight | Reuse the portable engine, schemas, archive, provider capabilities, and CUJ corpus later. | +| Windows/Linux | Line of sight | Keep the portable engine free of Apple UI, lifecycle, storage, and audio assumptions. | +| Web/mobile web | Deferred | No implementation or prototype in this program; browser constraints do not shape current milestones. | + +## Voice-session state + +```mermaid +stateDiagram-v2 + [*] --> Preparing + Preparing --> Capturing + Capturing --> Finalizing + Finalizing --> Editing + Editing --> Formatting + Formatting --> Validating + Validating --> Delivering + Delivering --> Stored + Validating --> Stored: No target or explicit save + Preparing --> Failed + Capturing --> Recovery + Finalizing --> Recovery + Formatting --> RawFallback + RawFallback --> Delivering + RawFallback --> Stored + Delivering --> Recovery + Recovery --> Stored + Failed --> Stored: Recoverable evidence exists + Stored --> [*] +``` + +Persistence and target delivery are independent outcomes.

Inference, +encoding, persistence, indexing, UI publication, and delivery consume outside +the callback and cannot apply backpressure to it. Overflow is a typed failure, +not silent audio loss. + +This is an in-process library design. A local REST daemon would add process +lifecycle, authentication, serialization, installation, and latency costs +without improving local portability. HTTP belongs only in later remote provider +adapters. + +## Model stages and options + +Use two specialized model stages with deterministic processing around them: + +1. a small VAD/segmentation step identifies speech boundaries; +2. an ASR model converts audio into timed Raw transcript revisions; +3. deterministic spoken-edit logic applies explicit corrections; +4. a small text model optionally creates structured paragraphs and lists; and +5. a deterministic validator and renderer reject unsupported additions and + produce Delivered text. + +One audio-language model is not the default. It couples transcription and +rewriting, weakens streaming and raw-history recovery, raises mobile resource +requirements, and makes failure harder to isolate. A future composite provider +may be benchmarked, but it must emit the same evidence-bearing stages. + +### ASR candidates + +| Option | Streaming/file | Portability | Planned role | +| ---------------------------------------------------------------------------- | -------------------------------------------- | --------------------------------------------------------------------------------- | ----------------------------------------------------------- | +| Apple Speech/SpeechAnalyzer | Native live and file capabilities vary by OS | macOS/iOS only | Existing baseline and Apple fallback. | +| sherpa-onnx with a streaming Zipformer or supported Whisper/Parakeet package | Strong local streaming/offline surface | macOS, iOS, Android, Linux, and Windows; Rust API over optimized native kernels | Leading portable spike. | +| WhisperKit/Core ML | Live and file | macOS/iOS | Apple-optimized comparator. | +| whisper.cpp with quantized Whisper | Live chunking and file | Broad native and WASM; C++ kernel behind Rust validation and a narrow C bridge | Selected first iOS file-ASR provider. | +| Candle Whisper | Model-dependent | Rust-first with Metal/CUDA/CPU | Rust-purity research candidate, not assumed mobile default. | + +Model packages initially benchmark: + +- a streaming sherpa-onnx Zipformer for first-partial latency; +- NVIDIA Parakeet TDT 0.6B v3 where language/device constraints fit; +- quantized Whisper large-v3-turbo for multilingual quality; and +- the current Apple on-device recognizer as the integration baseline. + +Qwen3-ASR remains a file/offline research candidate until its portable streaming +path is measured. No model wins by reputation: select per device tier using the +shared corpus and published quality, latency, memory, energy, size, and license +evidence. + +### Formatting candidates + +| Option | Portability | Planned role | +| --------------------------------------------- | -------------------------------------------------- | --------------------------------------------------------- | +| Deterministic punctuation/list/filler rules | All platforms | Always-available no-model fallback. | +| Apple Foundation Models `SystemLanguageModel` | Eligible macOS/iOS devices with Apple Intelligence | Zero-download Apple provider when available. | +| Existing Ollama Qwen3.5 4B | macOS | Development and desktop quality baseline. | +| `mistral.rs` with Qwen3.5 0.8B or 4B | Rust, Metal/CPU; mobile packaging must be proven | Preferred Rust-native portable spike. | +| `llama.cpp` with quantized Qwen | Broad optimized C++ backends | Portable comparator if the Rust-native path misses gates. | + +The Formatting provider receives text, never audio. A small 0.8B-class model is +the mobile target; desktop may use 4B when latency and memory gates pass. Styles +are versioned data, not prompts scattered through UI code. + +### Runtime policy + +Own orchestration, schemas, retention, validation, and provider APIs in Rust. +Prefer a proven Rust-native model engine when it meets measured gates. Permit +optimized C/C++ kernels such as sherpa-onnx, ONNX Runtime, whisper.cpp, or +llama.cpp only behind a narrow Rust safety boundary. Do not rewrite mature SIMD, +Metal, or Core ML kernels merely to satisfy language purity. Go has no planned +hot-path role because it adds another runtime without a model-serving advantage +on Apple devices. + +The first engine spike selects a narrow synchronous C ABI under +[decision 0035](decisions/0035_portable_voice_c_abi.md). Caller-owned buffers, +versioned layouts, no retained pointers or callbacks, and a real C consumer +make ownership explicit and let thin Swift/Kotlin wrappers remain typed. The +dependency-free Rust domain imports no Apple type. Reevaluate UniFFI for a later +object-heavy or asynchronous boundary when its Swift 6 `Sendable` support meets +the same gates. WASM compatibility is not a current selection gate. + +Decision [0042](decisions/0042_ios_whisper_file_asr.md) selects the official +whisper.cpp `b4938` XCFramework for the first iOS completed-file adapter. Rust +revalidates the active package and resolves the digest-verified model role; a +Swift actor exclusively owns the opaque C runtime context and prewarms it. +Framework and model binaries stay out of source control. sherpa-onnx remains +the streaming challenger and must beat the same physical-device corpus. + +Decision [0043](decisions/0043_ios_local_formatting_and_history.md) compiles the +existing deterministic spoken-edit, semantic-document, renderer, Style, and +retention sources into the iOS app. The containing app keeps the full Raw stage, +commits Raw/Edited/Formatted plus copied audio and model evidence to system +SQLite before publishing keyboard-ready text, and applies the accepted iOS +90-day/1-GiB/2,000-artifact limits. A later local text-model adapter may improve +surface style, but it must preserve these stages and deterministic fallback. + +Decision [0044](decisions/0044_ios_style_qualified_keyboard_delivery.md) keeps +separate app and keyboard surface defaults, freezes the keyboard selection on +the exact schema-V2 stop command, and maps its stable identifier into the +canonical formatter only inside the containing app. A session insertion receipt +wins over any later sequence for the same session and is durably claimed before +the host field changes. + +Decision [0045](decisions/0045_ios_host_field_and_delivery_target_safety.md) +permits Voice only for recognized general-text traits and binds delivery to one +ephemeral session/document/change-revision tuple. It retains neither target text +nor host identity; any mismatch recovers from History. + +Decision [0048](decisions/0048_ios_bounded_insertion_recovery.md) preserves one +automatic attempt and adds one explicit same-process retry plus local-only, +expiring copy. Recovery requires the exact claimed result and unchanged target; +History remains authoritative across ambiguity or process loss. + +## Formatting and backtracking + +The spoken-edit engine handles high-confidence commands before generative +formatting: + +- `scratch that` removes the current clause since the last stable pause; +- `delete that sentence` removes the current sentence; +- `new paragraph` emits a paragraph boundary; +- `start a numbered list` and `end list` emit structure boundaries; and +- `literal …` forces the following command phrase to remain text. + +Do not ask a language model to infer destructive edits without evidence. The +formatter may remove fillers, resolve an immediate restatement, punctuate, and +choose paragraph/list blocks. Validation rejects semantic additions, protected- +token changes, invalid structure, and output with no transcript evidence. + +Style resolution order is: + +1. explicit Voice session Style; +2. target application Style where target identity is available; +3. active Profile Style; +4. surface default, such as iOS keyboard; +5. device default; and +6. product default. + +Initial Styles are Natural, Casual Message, Formal, Technical, and Verbatim. + +The current macOS M4 baseline implements the machine-wide General selection, +product-default fallback, and typed replayable spoken edits. Its Swift spoken- +edit schema/engine/replayer, formatting schema, validator, renderer, and +fixtures are the conformance source for the later Rust extraction; target-, +Profile- and device-specific Style overrides remain future resolution inputs; +iOS now implements explicit app and keyboard surface defaults. + +## Durable local History and storage caps + +Use system SQLite for metadata, transcript stages, and search; store at most one +retained audio file per Voice session. Search indexes, decoded PCM, waveform +summaries, and model caches are derived and rebuildable. Do not create one file +per transcript revision. + +| Class | Recommended default | Eviction | +| ------------------------------------ | -------------------------------------------------------- | --------------------------------------------- | +| Successful-session audio on macOS | 90 days, 2 GiB, and 5,000 artifacts; first limit reached | Oldest unpinned audio first. | +| Successful-session audio on iOS | 90 days, 1 GiB, and 2,000 artifacts; first limit reached | Oldest unpinned audio first. | +| Transcript/session metadata | Retain until explicit deletion | Not automatically removed when audio expires. | +| Derived waveform/decoded/model cache | 256 MiB per device | Least recently used; always rebuildable. | +| Installed model packages | 12 GiB and eight versions on iOS; separate from History | Never evict implicitly; explicit removal only. | +| Partial/recovery artifacts | 24 hours after reconciliation | Remove only after a typed recovery decision. | + +Age, byte, and artifact-count limits are independently configurable; `Unlimited` +is an explicit choice. Users can pin important audio. Retention never removes an +active session, a pinned artifact, or the only recoverable evidence for an +incomplete session. When audio expires, its transcript remains searchable and +the detail view says why playback is unavailable. + +Enforce quotas after session finalization and at startup on a utility executor, +never on the capture or delivery path. Evict to 90% of the configured byte limit +to prevent deletion churn. Low-disk handling may temporarily override normal +cleanup timing but must use the same deterministic order and disclose every +removal. + +On iOS, a versioned local preference exposes restrained age, byte, and count +presets. Future or invalid preference bytes are preserved and become read-only. +The repository requests basic volume capacity and restores a 1 GiB reserve; it +never calls the important-usage capacity key. Maintenance runs after durable +commit, on History access, and after a settings change. Failure leaves committed +evidence usable, displays one retryable status, and never blocks delivery. + +Write audio to a session-scoped partial file, finalize and sync it, atomically +move it to its permanent name, then commit the SQLite transaction. Startup +reconciles partial and orphaned files. Portable V1 export contains a versioned +`manifest.json`, `checksums.json`, and optional `audio.caf`. Import snapshots the +package privately, enforces configurable byte/result caps, verifies the exact +inventory and digests, and restores the immutable result graph without delivery. +The final pre-portable revision 4 `session.json` remains importable on macOS. + +Deletion removes the owned record and files. Product copy must not promise +secure erasure from SSD wear-leveling, filesystem snapshots, or device backups. + +The current M14 macOS baseline stores linked immutable results in SQLite, +searches every text stage, plays bounded timed CAF spans, and supports explicit +correction, retranscription, reformatting, re-delivery, export, pinning, and +transactional deletion. A portable policy plus dedicated SQLite retention actor +enforces age, count, byte low-water, and low-disk rules after finalization and at +startup while preserving searchable transcript metadata and typed expiration +evidence. Startup reconciliation now repairs interrupted expiration, converts +readable partial and orphan audio into typed Recovery sessions, isolates +malformed rows, preserves physically corrupt databases, and retains completed +text when audio finalization fails. Recovery audio remains playable and locally +retranscribable for 24 hours unless pinned. + +M12 adds a native History import path: it validates independent source-byte, +decoded-byte, and duration limits, balances security-scoped access, streams a +supported external recording into one app-owned CAF, and stores typed +imported-audio provenance. The original file remains untouched. Apple +on-device ASR and the selected local Style run before commit; ASR and formatting +fail independently to audio-only and transcript-only History evidence. +Formatting adapters now declare typed identity and locality. The router rejects +remote-capable adapters before any invocation, while in-process Apple and fixed- +loopback Ollama remain independent of external network availability. Formatting +failure delivers deterministic Edited text after target validation. ASR failure +after capture retains playable audio, stores truthful empty stages, and marks +delivery not attempted. + +## Privacy and security + +Local-only is a product invariant: + +- No accounts, analytics, telemetry, remote inference, remote storage, or sync + ship in the local-only milestones. +- Capture occurs only during a confirmed, visibly indicated owned session. +- Secure targets are rejected. Target context is bounded and absent from + terminals, browser URLs, screenshots, pasteboard history, and whole documents. +- iOS uses the strongest Data Protection class compatible with intentional + background capture. The keyboard shares only bounded, this-device-only + Keychain state and no audio or target context. +- Model packages carry identity, digest, license, capability, and size metadata. +- M13 validates the V1 package schema in portable Rust before installation or + inference: strict typed metadata, configurable manifest/file/byte limits, + portable paths, no links or undeclared payloads, exact sizes and SHA-256, + mandatory notice evidence, and optional out-of-band manifest pinning. +- M14 validates bounded V1 History archives in Swift and portable Rust, checks + the same source-controlled fixture through the C ABI, and treats self-declared + checksums as integrity rather than external authenticity. +- Explicit Model-package downloads are allowed before capture from approved + sources, contain no Voice content, and require digest/license verification. +- Mark owned Voice stores and artifacts as excluded from OS backup where the + platform supports it. Disclose that manual and external backups remain beyond + the app's secure-erasure guarantee. +- A provider declaring remote capability is rejected before it receives audio, + text, context, or history in local-only mode. +- Every iOS check rejects network clients, Network.framework linkage, + transport-security configuration, push, associated-domain, iCloud, and + networking capabilities in product sources and configuration. + +API-powered providers are a separately approved milestone. They must be +explicitly enabled and visible per session, minimize payloads, define retention, +support cancellation, and preserve a local fallback. A provider seam does not +authorize network code now. + +## Latency and quality gates + +Measure on the reference and lowest-supported device for each platform. Report +p50, p95, p99, maximum, sample count, model identity/digest, cold/warm state, +thermal state, audio duration, and power mode. + +| Interval | Proposed warm target | +| -------------------------------------------- | -----------------------------: | +| Trigger callback to accepted capture command | p99 ≤ 15 ms | +| Accepted command to first owned PCM frame | p95 ≤ 150 ms; maximum ≤ 250 ms | +| Speech onset to useful provisional text | p95 ≤ 750 ms | +| ASR decoding real-time factor | p95 ≤ 0.5 | +| Stop to Raw transcript | p95 ≤ 600 ms | +| Stop to validated Delivered text | p95 ≤ 1.5 s; maximum ≤ 3 s | +| Completed session to searchable History item | p95 ≤ 250 ms | + +Quality gates include word-error rate, proper-noun recall, revision stability, +spoken-command precision/recall, filler-removal precision, list accuracy, +protected-token preservation, semantic-addition rejection, audio-drop count, +peak memory, installed size, and energy per audio minute. + +## Program delivery and test balance + +Use `dev` as the integration branch. Each coherent vertical slice uses a fresh +`codex/voice_*` branch in a separate Git worktree and a focused pull request into +`dev`. A slice includes its acceptance/documentation change, behavior test, +implementation, migration, and verification where those responsibilities change +together. Do not use layer-only batches or unrelated cleanup to manufacture PR +boundaries. + +Merge a PR to `dev` after required checks pass when repository policy permits. +If policy requires unavailable human review, keep later work in explicit stacked +PRs without bypassing protections. `main` remains unchanged until the complete +`dev` state receives user verification and separate merge approval. + +Testing uses four complementary levels: + +| Level | Purpose | Rigidity policy | +| --- | --- | --- | +| CUJ contract | Fast regression spine through public Voice behavior | Stable outcomes; deterministic providers; no internal call/layout assertions. | +| Adapter integration | Real SQLite/files, audio conversion, FFI, shared Keychain, lifecycle, and delivery seams | Assert boundary contracts, not third-party implementation details. | +| E2E/system | A small set of highest-risk complete macOS and iOS paths | Use accessibility identifiers and user outcomes; do not multiply tests across every combination. | +| Model/performance | Production model quality, latency, memory, energy, and provenance | Use semantic invariants and bounded metrics, not brittle exact prose. | + +Intentional behavior changes may update a CUJ and its test in the same PR when +the rationale and equivalent safety coverage are explicit. This keeps the E2E +spine strong without turning exploratory architecture or model work into +snapshot maintenance. + +## CUJ-first TDD roadmap + +[`voice_cujs.md`](voice_cujs.md) is the acceptance authority. Each implementation +slice follows red → green → refactor through public behavior. Do not write every +test first or batch the entire implementation behind mocked internals. + +### C0 — integrate contracts and prove the harness + +- Reconcile the accepted decision, canonical language, CUJ observations, + retention defaults, and current source without reopening approved choices. +- Establish `dev`, the per-PR worktree workflow, and required CI checks. +- Create the repository directory skeleton only as needed by the first test. +- Add one failing, deterministic Mac CUJ M1 tracer test using a short sanitized + audio fixture, fake capture clock, temporary repository, and fake delivery + boundary. +- Implement the minimum vertical path to make M1 pass while preserving current + Local Dictation behavior. +- Establish performance measurement and local-only network-denial fixtures. + +### C1 — macOS daily voice writing + +- Implement M2–M5 one failing behavior at a time: latch, formatting and Styles, + backtracking, and safe focus/delivery recovery. +- Add one History path before expanding its UI: stored audio, timed transcript, + playback, and retry. +- Extract existing code into `apps/macos/` only at boundaries exercised by a + green test. + +### C2 — portable model and storage spine + +- Retention tracer complete: one shared CUJ fixture passes through the Swift + baseline and dependency-free Rust policy; the versioned C ABI passes layout + and real-consumer checks. +- Benchmark ASR candidates against the same corpus and device tiers; publish the + selection evidence before choosing defaults. +- Introduce the Rust engine behind the stable CUJ contract; run the same tests + against Swift baseline and Rust implementation during migration. +- M6–M12 now pass for History, retention, crash recovery, imported files, + offline enforcement, trigger convergence, portable retention, and model + fallback. +- M13 now passes one shared Model-package fixture through bounded Rust + verification and the versioned caller-owned C ABI; no inference runtime or + default package is selected by that admission contract. +- M14 now passes one shared History archive fixture through Swift, Rust, and the + caller-owned C ABI. macOS V1 export/restore is transactional, idempotent for + identical evidence, conflict-safe for reused UUIDs, and migrates revision 4. +- M15 statically links the Rust ABI into the Apple executable behind typed, + pointer-free Swift values. Production V1 import verifies the private snapshot + in Rust before complete Swift graph validation and transactional restore; + digest-stamped builds cannot silently reuse stale Rust code. +- Design separate streaming ownership before exporting ASR or formatting; do + not assume the synchronous retention ABI fits an async model boundary. + +### C3 — macOS hardening + +- Complete long-session, corruption, migration, permission, Accessibility, + latency, memory, energy, signing, installation, and removal evidence. +- Validate Messages, Notes, mail, browsers, terminals, coding tools, and long AI + prompts without claiming unsupported target behavior. +- Publish no binary until its exact version receives separate release approval. + +### K0 — iOS keyboard feasibility gate + +- **Implemented:** the containing app owns local PCM capture and its CAF; a full + QWERTY keyboard remains usable without Full Access; and app, keyboard, and + Control Center extension exchange only bounded local Keychain state. +- **Implemented:** `AudioRecordingIntent`, Live Activity, heartbeat, single-slot + commands, stale-session policy, one-time insertion, and honest cold-start + guidance use documented public APIs. The keyboard never opens the app. +- **Evidence:** 14 unit tests, two containing-app UI tests, a real 51,188-byte + simulator capture, Messages typing/insertion/manual de-duplication, and a + strictly verified generic-device build signed by the configured Team. The + 100-round-trip Keychain handoff measured p50 0.819 ms, p95 1.047 ms, and max + 2.990 ms on the reference Mac/simulator pair. +- **Open evidence:** install and exercise the same build on the available + physical iPhone after one of its three unrelated free-profile development + apps is removed; benchmark production ASR/formatting on the lowest intended + iPhone during C4. Neither blocks independent C4 work. + +### C4 — iOS containing app and keyboard + +- Implement onboarding, model management, History, and in-app local capture. +- **Current evidence:** the K0 project is promoted to + `apps/ios/voice_input/` with the production identity, local-first permission + disclosure, explicit microphone request/recovery, exact keyboard guidance, + and same-device Full Access confirmation. Four policy tests and one real + Keychain integration test extend the 14-test K0 baseline. Four + presentation-model tests isolate permission and handoff failures, and a + focused UI test keeps capture reachable at an accessibility text size. +- **Current Model evidence:** the iOS app links the optimized portable Rust + validator for device and simulator, imports under security-scoped access, + applies independent staging limits, atomically installs valid packages into + protected backup-excluded storage, and labels unpinned origin honestly. The + library applies injected total-byte and package-version limits, defaulting to + 12 GiB and eight versions, and supports explicit removal without silent age + eviction. Fourteen focused unit/integration cases cover the model library, + real linked fixture, limits, links, tampering, identity, idempotence, cleanup, + removal, and corrupt records; the cold-launch UI CUJ requires the import + surface. +- **Current ASR evidence:** one compatible package can become the persisted + active ASR model; app launch, selection, and capture prewarm its exclusive + whisper.cpp context. Rust revalidates the exact manifest and every payload + before returning one model path. Stop converts the real CAF to timed Raw text + through bounded caller-owned buffers. A pinned native integration corpus + measured warm CPU RTF 0.0111 on the reference Mac; the UI fails explicitly + when no model is selected. The containing app now applies shared deterministic + formatting, commits bounded History before publish, and accepts an exact + Style-qualified keyboard stop. Real-Keychain tests prove warm stop/ready and + session-level automatic replay suppression. Typed UIKit traits now disable Voice in + constrained or unverified fields without disabling QWERTY, and an opaque + document/session plus host-change revision prevents late target-state + insertion. Physical-iPhone + percentiles and keyboard evidence remain open because its free profile is at + the three-app limit. +- **Current lifecycle evidence:** the containing-app actor maps every audio + interruption, route, background, Low Power Mode, and thermal event into an + explicit continue/stop decision. Visible Live Activity ownership is required + for background recording. Stop receives a bounded background task; expiration + invalidates late finalization and commits exact partial audio to Recovery + History. Startup reconciliation runs on first History access, adopts only + readable canonical session artifacts, preserves damaged/unknown files, and + never auto-resumes. Decision + [`0046`](decisions/0046_ios_capture_lifecycle_and_recovery.md) owns I7. +- **Current stale-service evidence:** Recording and Transcribing maintain one + phase-aware heartbeat task. Missing, future, expired, and unknown-schema + active state stops the keyboard wait within three seconds and exposes one + honest restart-instruction action. Result sequencing and the durable receipt + reject regressed or same-session replay. Policy, actor, and real-Keychain + tests cover I8; physical kill/suspension/upgrade evidence remains open. + Decision [`0047`](decisions/0047_ios_stale_service_recovery.md) owns I8. +- **Current insertion-recovery evidence:** an unconfirmed insertion exposes one + bounded `Recover…` surface. A single explicit retry and ten-minute local-only + copy require the exact Ready result, durable receipt, document, and host-change + revision; every mismatch recovers from History. The app History surface also + offers bounded copy. Pure policy tests run within the complete simulator + build; host-specific callback and rejection behavior remains physical-iPhone + evidence. Decision + [`0048`](decisions/0048_ios_bounded_insertion_recovery.md) owns I9. +- **Current offline-storage evidence:** History revision 3 persists pin state; + local versioned presets apply age/count/byte and 1-GiB-reserve cleanup after + durable commit without turning maintenance failure into delivery failure. + Real repository tests cover migration, protected Recovery audio, low disk, + Data Protection where CoreSimulator exposes it, and backup exclusion. Model + admission regressions prove byte/version rejection leaves installed packages + unchanged. A static local-only check runs before every iOS build. Decision + [`0049`](decisions/0049_ios_offline_storage_enforcement.md) owns I10; + physical airplane-mode evidence remains final signed-device work. +- **Current system-capture evidence:** a stateful Control Center/Lock + Screen/Action button control, Siri/App Shortcuts, and Live Activity stop use + Audio Recording intents and the bounded exact-session command slot. Control + state reloads only on Recording transitions. Relaunch ends orphaned visible + ownership, marks the stale session Interrupted, and preserves partial audio + for History. Copy/share and later keyboard retrieval are explicit; target + inference is absent. Decision + [`0050`](decisions/0050_ios_system_surface_capture.md) owns I11; physical + system-surface evidence remains final signed-device work. +- Every repository check runs the real pinned native transcription and output + safety assertions. `HC_RUN_IOS_ASR_PERFORMANCE=1` additionally enforces the + RTF ≤ 0.75 gate only on named hardware; shared virtual CI is not performance + evidence. +- Keep I1–I11 regressions outcome-based: exact ownership, bounded commands, + visible recording, durable History, and explicit delivery. +- Run signed-device UI tests for behaviors extension simulators cannot prove. + +### C5 — preserve later portability + +- Run portable-core conformance and compile checks that prevent Apple-only types + or lifecycle assumptions from entering the Rust boundary. +- Document the later adapter seams for Android, Windows, and Linux without + building speculative applications. +- Keep web and mobile web outside the program; do not add WASM/WebGPU work. +- Design
