# Changelog

All notable changes to D3RO Voice will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

### Planned
- macOS / Linux support
- Additional Whisper model management UI
- Cloud-optional backup (encrypted, opt-in)
- Plugin system for custom pipelines

## [1.4.0] - 2026-09-21

### Added
- **Several shortcuts per action.** Every action now holds a list of bindings
  instead of a single one, so a second (or third) shortcut can be added with the
  `+` button and removed individually.
- **Mouse buttons as shortcuts.** Side buttons (back / forward) can be bound on
  their own; right and middle click require a modifier. Left click cannot be
  bound because it drives every on-screen interaction. Mouse events cannot be
  swallowed, so a bound button still performs its original action — the settings
  screen says so before the binding is saved.
- **Pick a key from a searchable list.** Besides pressing the key, a shortcut can
  now be chosen from a grouped dropdown with a search box inside it, which also
  makes keys reachable that are awkward to press while recording.
- **The history and command popups are rebindable.** `Ctrl+Shift+V` and
  `Ctrl+Shift+C` were fixed in code and had no settings entry; they are now
  ordinary actions. The voice command shortcut, which had never been exposed in
  settings, is visible as well.

### Fixed
- **Double-press hands-free never triggered.** Dictation and hands-free ship with
  the same default key and are told apart by the double press, but shortcut
  lookup stopped at the first match, so hands-free was unreachable in installed
  builds. Both actions now receive the event and are split by press type.
- **Reserved system shortcuts could be assigned anyway.** The check compared
  joined key names, so pressing the modifiers in a different order let `Ctrl+C`
  and friends through. Combinations are now compared structurally.
- **Turning shortcuts off also killed the popup shortcuts permanently.** Disabling
  global shortcuts released every registration in the process, including ones it
  did not own, and re-enabling never restored them.
- **Enabling shortcuts after starting with them off left nothing bound.**
- **Shortcut labels were frozen in the language they were recorded in** and did not
  follow the app language or platform conventions. They are now derived on display.
- **The dashboard caption indicator never reflected the real state** because the
  event payload was stored instead of the state inside it.

### Changed
- Shortcuts are stored as one list per action. Existing shortcuts are migrated
  automatically on first launch; no reconfiguration is needed.

## [1.3.7] - 2026-09-19

### Fixed
- **Recording and live caption overlays never worked in installed builds.** Popup
  pages loaded their scripts as classic `<script src>` tags, which the renderer
  build does not bundle, so a packaged app rendered only the static markup: the
  recording tip froze at 0:00 with no wave bars and captions showed nothing.
  Popup scripts are now module scripts, a packaging check fails when a renderer
  page references an asset that was never emitted, and popups hold IPC until
  their renderer is ready and re-assert visibility on every show.

## [1.3.6] - 2026-09-18

### Fixed
- **Installing the local speech engine always failed** with a hash mismatch, leaving local
  transcription unusable. The downloaded parts were checked against bytes counted from the
  network stream, while the joined archive was checked against what was actually written to
  disk, so a truncated write passed part verification and only surfaced later as an archive
  mismatch with no usable diagnostic. Every check now reads the file on disk, the joined
  archive is size-checked before hashing, mismatch errors report the actual and expected
  values, and a failed part is discarded and retried up to three times.

## [1.3.5] - 2026-09-18

### Fixed
- The Ollama guide still listed the retired  models as its recommendation while the
  app already defaults to . The guide now leads with the model the app actually
  uses and lists current lightweight alternatives.

## [1.3.4] - 2026-09-18

### Fixed
- **Automatic updates could not start on 1.3.3**: its installer was missing the updater
  configuration file, because the packaging path used to guarantee the native module build
  does not create it. The file is now written from the single feed source and its presence
  in the packaged app is verified before publishing, so an installer that cannot update is
  never shipped.

## [1.3.3] - 2026-09-18

### Fixed
- **The released installer could not start**: it carried a `better-sqlite3` build for the
  host Node runtime instead of Electron, so the app failed immediately with a
  `NODE_MODULE_VERSION` mismatch when opening its database. Packaging now guarantees and
  verifies the Electron build of every runtime-sensitive native module before an installer
  or archive is produced, and publishes only from that verified tree.
- **The local language model default still pointed at a retired model**: the stored default
  was a `*.gguf` file name that Ollama cannot serve, and the settings, onboarding, and
  Ollama guide still recommended `gemma2:2b` while the service code already preferred
  `gemma4:e4b`. All surfaces now default to `gemma4:e4b`.

## [1.3.2] - 2026-09-18

### Changed
- **Auto-update works again**: the installer no longer carries the local speech engine
  and ffmpeg. Bundling them pushed the installer to 189 MB, and the download feed sits
  behind Cloudflare, which rejects uploads over ~100 MiB with HTTP 413 — so update
  metadata could not be published at all. The installer is now 90.5 MiB and the update
  feed is published again.
- **The app fetches its speech engine and ffmpeg when they are first needed**, verifying
  every part and the joined archive by SHA-256 before installing them under the app data
  folder. Updates stay small (the engine is not re-downloaded on every release), and the
  Settings > STT tab shows the runtime status with a manual download action.

## [1.3.1] - 2026-09-18

### Fixed
- **Manual install no longer needs 7-Zip**: the signing-free channel now also publishes the
  app as byte-split `zip` parts. The install script joins them and extracts with the built-in
  Windows `Expand-Archive`, so a user with nothing but Windows can install (the 7z volumes
  remain the smaller Scoop path). Split volumes from a different build are never mixed:
  every artifact of a release comes from one build, and a published version is not overwritten.

## [1.3.0] - 2026-09-18

> Published from an annotated tag through CI. Installer and update metadata are
> served by the canonical Forgejo feed; no binaries are committed to this repository.

### Added
- **Live partial transcript while dictating**: while the hotkey is held, the app now
  transcribes the recent window of audio every 1.5 seconds and shows it in the recording
  tip, so the text can be seen forming before the key is released. Partials never reach
  the clipboard or the result popup; only the final transcription is inserted.
- **Instant first dictation**: the local speech engine (sidecar process + Whisper model)
  is warmed up in the background at app start, so the first press does not wait for the
  model to load.
- **Packaged local speech engine**: desktop installers now ship the faster-whisper
  sidecar (`sidecar.exe` plus runtime data, including the Silero VAD model) and ffmpeg, so
  local transcription works on a fresh install without Python on the machine.
- Sidecar build tooling: `npm --prefix apps/desktop run sidecar:setup` and
  `sidecar:build`, plus a packaging-time bundle verifier that fails the build when the
  engine or its VAD data is missing.

### Added
- **Signing-free install path (`portable` channel)**: the canonical feed sits behind
  Cloudflare, which rejects any upload body over ~100 MiB with HTTP 413 (measured:
  60 MiB accepted, 110 MiB rejected). The sidecar-carrying app exceeds that, so releases
  are now also published as 95 MiB 7z split volumes (688 MB app → 162 MiB) with a Scoop
  bucket manifest and a verifiable manual installer script. This channel never touches the
  auto-update feed and needs no Authenticode certificate, so users can install while the
  signing certificate is still being procured.

### Changed
- Local engine connections now target the IPv4 loopback (`127.0.0.1`) instead of
  `localhost`. On machines where `localhost` resolves only to IPv6, every local request
  (Ollama and the speech sidecar) was refused and local AI silently did nothing.
- Whisper decoding is tuned for dictation: previous-text conditioning is disabled so
  repeated hallucinations cannot compound, silence is trimmed more aggressively, and
  low-confidence fallbacks are bounded. Same transcript quality, roughly five times
  faster on the same machine.
- The sidecar reuses an already-loaded model instead of reloading it, and reports the
  load time it measured.
- Local engine logs stream to the app log as complete UTF-8 lines instead of mangled
  fragments, so failures are diagnosable.
- Failed local-engine startup now fails immediately with an actionable message (missing
  bundled engine, damaged virtualenv, or missing SoX) instead of waiting for a 30 second
  health check and reporting a generic error.

### Fixed
- **Local transcription never worked in packaged builds**: the sidecar was not part of
  the packaged resources and no pipeline step built it, so the app always fell back to a
  system Python that had no faster-whisper installed.
- **Local transcription and local LLM never worked in development**: the sidecar and SoX
  paths were resolved against the Vite output directory (`out/main`) instead of the app
  root, so recording failed with a SoX `ENOENT` and the sidecar fell back to a Python
  without the runtime dependencies.
- **Silero VAD data was missing from the bundled engine**, which would have made
  silence-trimmed transcription fail at runtime even with the engine bundled.
- Audio capture and the speech sidecar no longer flash a console window on Windows, and
  SoX/spawn failures name the fix (`npm --prefix apps/desktop run setup:sox`).

## [1.2.0] - 2026-09-16

> Published from an annotated tag through CI. Installer and update metadata are
> served by the canonical Forgejo feed; no binaries are committed to this repository.

### Added
- **Canonical desktop release channel**: desktop auto-update now reads one Forgejo Generic Package Registry feed, published by a version-agnostic publisher (`scripts/ci/publish-forgejo-release.mjs`) from tag-triggered Forgejo Actions, GitLab, and GitHub pipelines. The GitLab registry stays a legacy mirror for pre-Forgejo installs.
- **Update policy SSOT** (`release/update-policy.json`): channels (`latest`/`beta`/`alpha`), minimum supported version, forced install, full-installer thresholds, staged rollout percentage, and a remote kill switch, enforced at runtime by `apps/desktop/src/main/update-policy.ts`.
- **Dictionary import/export on desktop and web**: round-trip import with per-entry conflict reporting, a web dictionary client, and an expanded knowledge add form.
- **Multi-transport push delivery**: Web Push (VAPID) and token-based Apple Push (APNs) transports join Firebase Cloud Messaging, with a Cloudflare Worker cron drain over an outbox table.
- **Team activity feed**: team activity events, migration, and the web feed component.
- **Shared entitlement gating** in `@d3ro/core` for free/paid feature boundaries.
- **Infrastructure map** (`docs/map/`) documenting the infrastructure and feature status per platform, with an update protocol so feature work and the map stay in step.
- 21 unit tests for update policy decisions and feed helpers, plus tests for dictionary I/O, entitlements, push drain, Web Push, and APNs payloads.

### Changed
- Desktop runtime updater feed moved from GitLab project 1172 to the canonical Forgejo registry; `electron-builder.yml`, the metadata verifier, and both CI publishers now enforce the canonical/mirror split.
- Release metadata verifier self-test expanded to negative cases covering the feed contract, policy schema, and Forgejo publisher invariants.
- The canonical publisher refuses to re-publish a version whose registry assets already hold different bytes, so a same-version re-release fails closed instead of overwriting a shipped installer.
- Landing site and web console download centers now link the canonical Forgejo feed instead of repository-local installer paths, which are not part of any deploy artifact.
- Admin console data views (models, pipelines, users, subscriptions, audit log) read live back-office data, with a unified sidebar and console theme.
- Desktop settings, ad surfaces, license, and meeting-export UI aligned on the shared theme tokens; meeting export filenames now go through one sanitizer.
- Developer-only automation, scratch captures, .NET build output, and Playwright run output left the release checkout.
- Product version moved to `1.2.0` with Android version code and iOS build number `1020001`.

### Fixed
- Desktop configuration writes fail explicitly when the config store is unavailable instead of falling back to a throwaway in-memory store.
- Speech provider and model failures reach the UI as errors instead of surfacing as empty transcriptions.
- Removed the Forgejo release-publishing prohibition; the legacy hardcoded-version script is replaced by a version-gated publisher.
- Dropped a stale admin bundle from the API server web root.
- Mobile team, meeting, memo, template, command, and dictionary screens follow the server contract, and report submission no longer hangs without confirming to the user.

## [1.1.0] - 2026-08-29

### Added
- **Android/iOS product mobile app**: implemented account bootstrap and lifecycle, onboarding, recording and audio import, transcription, history, meetings, templates, memos, teams and invitations, notifications, knowledge, AI Talk, generated documents, data portability, and role-aware administration flows.
- **Mobile-native recording and intake**: added Android foreground recording with persistent controls and recovery, external `ACTION_SEND` audio/video intake, durable upload processing, and supported-device on-device Whisper transcription.
- **Server-verified mobile monetization**: added Google Play purchase and restore verification, entitlement reconciliation, AdMob rewarded SSV validation, and replay-safe reward receipts.
- **Generated-content safety controls**: added generation receipts, shared generative-AI safety instructions, and an authenticated report flow for owned AI-generated meeting documents.
- **Release verification tooling**: added Android artifact, App Links, production Firebase/AdMob configuration, Play asset, secret scanning, signed provenance, and publication-boundary checks.
- **Complete mobile icon set**: added canonical Android legacy/adaptive/monochrome launchers, the 512px Play icon, and all required iPhone, iPad, and App Store marketing icon slots.

### Changed
- Unified mobile authentication and invitation links on the canonical `d3ro-voice` app scheme and added fail-closed verification for the HTTPS App Links contract.
- Hardened Supabase and mobile production configuration to fail closed when required public configuration is absent or does not match the release identity.
- Expanded CI coverage across Node.js 24, .NET 10, Deno Edge Functions, React Native tests, Android emulator gates, 16 KB page-size compatibility, and reproducible release evidence.
- Aligned account deletion guidance with external subscription cancellation requirements and centralized local sensitive-data purge on logout, account deletion, and session loss.
- Centralized product version `1.1.0`, Android version code `1010001`, release notes, updater metadata, and app-store changelogs under release SSOT checks.
- Finalized benchmarked `ko-KR`/`en-US` Play listing copy and a Console-previewed
  1024×500 canonical feature graphic with preserved generation prompt, source,
  output, and hashes.

### Security
- Added atomic authorization and replay protection for teams, invitations, push delivery, transcription quotas, billing, ad rewards, administrative actions, data portability, and content reports.
- Removed synthetic success fallbacks from protected STT and AI paths; provider and configuration failures now return explicit failures without creating fabricated user data.
- Strengthened generated-document reporting so only the owner can report an existing document backed by immutable generation audit evidence.
- Removed the repository-exposed desktop license private key and prefix-only paid-tier activation; production now accepts only Ed25519 licenses signed by the rotated external key.
- Made Windows stable packaging fail closed unless an external public-trust code-signing PFX is provided and both the NSIS installer and unpacked app pass exact-version, updater SHA-512, Authenticode `Valid`, and expected signer-subject verification; local self-signed development certificates are rejected.

### Fixed
- Corrected realtime Edge Function model routing and type checks for team and enterprise tiers.
- Removed the legacy `d3ro://` deep-link surface to prevent divergent authentication callback identities.

## [0.2.1-alpha] - 2026-07-22

### Fixed
- **v0.2.0-alpha 치명적 버그 (앱 실행 불가)**: refactor-wave WS2(AppConfig SSOT)에서 7개 키(`customInstructions`, `llmChains`, `voiceCommandRules`, `voiceCommandsEnabled`, `activeInstructionId`, `activeChainId`, `captionAudioSource`)를 AppConfig 인터페이스에 추가하고 `as never` 16건을 제거했으나 **`CONFIG_DEFAULTS`(ConfigService.ts) 기본값을 누락** → 기존 사용자 config(0.1.x) 마이그레이션 시 `configGet()`이 `undefined` 반환 → main 프로세스 `.map()` 크래시. `CONFIG_DEFAULTS`에 기본값(`[]`, `[]`, `[]`, `false`, `''`, `null`, `'mic'`) 추가.
- **교훈**: typecheck/lint/unit test가 GREEN이어도 런타임을 보장하지 않음. **배포 전 `npm run dev` 실행 + 산물 설치 e2e 필수** — 이번에 e2e를 건너뛰어 사용자가 발견.

## [0.2.0-alpha] - 2026-07-22

> **다운로드**: Windows `D3RO-Voice-Setup-0.2.0-alpha-x64.exe` · macOS `D3RO-Voice-0.2.0-alpha-arm64.dmg`
> (Release assets 첨부) — 기존 Windows 사용자는 자동 업데이트(4시간 주기)로 수신됩니다.
> macOS는 ad-hoc 서명 — Gatekeeper 차단 시 우클릭→열기.

### Fixed
- **한국어 날짜 "TODAY"/"YESTERDAY" 표시 버그** — `date.today/yesterday` 중복 정의(JSON last-wins) 해소
- **팝업/렌더러 색상 충돌** — 팝업이 v1 주황(`#f25b29`)으로 렌더되던 것을 파랑(`#3b82f6`)으로 SSOT 정합
- **받아쓰기 파이프라인 4버그**: press 액션이 STT 초기화를 await하며 큐 점유→release 지연/유령 세션; 사이드카 crash 루프; RecordingTip hide 타이머 leak; 빈 STT 가드
- **온보딩 무진행 구간 UX**: verifying(모델 검증) 단계 피드백 + 중복 실행 가드
- **마이크 테스트 조기 종료**: 초기 `level:0`을 종료 신호로 오인하던 버그
- **트레이 아이콘 빈 이미지** 버그

### Changed
- **`accent.amber` → `accent.main` 전면 통일** (162건, deprecated 별칭 2곳 제거) — desktop/web/admin/mobile/ui-native 전역. 6 테마 일관.
- **IPC 채널 SSOT 일원화**: `ipc-channels.ts`에 9 그룹/키 추가(INSTRUCTION, POPUP_*, CLIPBOARD, APP 등), 하드코딩 채널 문자열 제거, `ipcSuccess/ipcError` 헬퍼 통일, `catch(error)` 패턴 32건
- **AppConfig 타입 강화**: 7개 누락 키 추가, `as never` 16건 제거, dynamic `require` → static import

### Removed
- DS 미사용 3종: **MetalDial, ButtonGroup, CrtDisplay** (barrel export 포함)
- **미사용 의존성 8종**: `@mui/icons-material`, `@d3ro/api-client`, `fluent-ffmpeg`(+`@types`), `pdf-parse`, `node-record-lpcm16`(+`.d.ts`), `electron-audio-loopback`, `@electron-toolkit/preload`
- **i18n 고아 키 967건** (12 locale) — camelCase license.feature 15키 등 동적 참조는 P1 재검증으로 보존
- `services/index.ts` 데드 레지스트리, `electron-builder.yml` Linux 섹션

### Internal
- **refactor-wave Wave 1+2**: 정책(`docs/REFACTOR_POLICY.md`) 수립 → 공격적 감사(106건) → 9 워크스트림 병렬 → 분리 커밋 9개 + 메타 2. 공유 패키지 토큰 SSOT, IPC/타입 정합, 데드코드 대량 제거. 보고서 `docs/REFACTOR_WAVE1_REPORT.md`·`WAVE2_REPORT.md`.
