chore: finalize v0.5.6 changelog fragments

- show a dedicated startup OSD "building" phase for character dictionary sync
- forward bare `Tab` from visible overlay to mpv so AniSkip works while focused
- fix Windows plugin env override resolution for `SUBMINER_BINARY_PATH`

-
-          ### AppImage (Recommended)
-          1. Download the AppImage below
-          2. Make it executable: `chmod +x SubMiner.AppImage`
-          3. Run: `./SubMiner.AppImage`
-
-          ### macOS
-          1. Download `subminer-*.dmg`
-          2. Open the DMG and drag `SubMiner.app` into `/Applications`
-          3. If needed, use the ZIP artifact as an alternative
-
-          ### Manual Installation
-          See the [README](https://github.com/${{ github.repository }}#installation) for manual installation instructions.
-
-          ### Optional Assets (config example + mpv plugin + rofi theme)
-          1. Download `subminer-assets.tar.gz`
-          2. Extract and copy `config.example.jsonc` to `~/.config/SubMiner/config.jsonc`
-          3. Copy `plugin/subminer/` directory contents to `~/.config/mpv/scripts/`
-          4. Copy `plugin/subminer.conf` to `~/.config/mpv/script-opts/`
-          5. Copy `assets/themes/subminer.rasi` to:
-             - Linux: `~/.local/share/SubMiner/themes/subminer.rasi`
-             - macOS: `~/Library/Application Support/SubMiner/themes/subminer.rasi`
-
-          Note: the `subminer` wrapper script uses Bun (`#!/usr/bin/env bun`), so `bun` must be installed and on `PATH`.

+## PR Feedback
+
+- Active PR: `gh pr view --json number,title,url --jq '"PR #\\(.number): \\(.title)\\n\\(.url)"'`.
+- PR comments: `gh pr view …` + `gh api …/comments --paginate`.
+- Replies: cite fix + file/line; resolve threads only after fix lands.
+- When merging a PR: thank the contributor in `CHANGELOG.md`.
+
+## Changelog
+
+- User-visible PRs: add one fragment in `changes/*.md`.
+- Fragment format:
+  `type: added|changed|fixed|docs|internal`
+  `area: <short-area>`
+  blank line
+  `- bullet`
+- `changes/README.md`: instructions only; generator ignores it.
+- No release-note entry wanted: use PR label `skip-changelog`.
+- CI runs `bun run changelog:lint` + `bun run changelog:pr-check` on PRs.
+- Release prep: `bun run changelog:build`, review `CHANGELOG.md` + `release/release-notes.md`, commit generated changelog + fragment deletions, then tag.
+- Release CI expects committed changelog entry already present; do not rely on tag job to invent notes.
+
+## Docs
+
+- The documentation for this project lives in a separate sister directory: [`../subminer-docs/`](https://github.com/ksyasuda/subminer-docs)
+- Read the [`../subminer-docs/development.md`](https://github.com/ksyasuda/subminer-docs/blob/main/development.md) and [`../subminer-docs/architecture.md`](https://github.com/ksyasuda/subminer-docs/blob/main/architecture.md) before making changes and follow the guidelines unless there is a specific reason to deviate
+- Make sure the changelog [`../subminer-docs/changelog.md`](https://github.com/ksyasuda/subminer-docs/blob/main/changelog.md) is updated on each release
+- Ensure the docs are kept up to date if any new or breaking changes are introduced
+- If the sister repo does not exist at `../subminer-docs`, then do not attempt
+  to update the docs and reference the files from GitHub if needed
+
+## Flow & Runtime
+
+- Use repo’s package manager/runtime; no swaps w/o approval.
+- Use Codex background for long jobs; tmux only for interactive/persistent (debugger/server).
+
+## Build / Test
+
+- Before handoff: run full gate (lint/typecheck/tests/docs).
+- CI red: `gh run list/view`, rerun, fix, push, repeat til green.
+- Keep it observable (logs, panes, tails, MCP/browser tools).
+
+## Git
+
+- Safe by default: `git status/diff/log`. Push only when user asks.
+- `git checkout` ok for PR review / explicit request.
+- Branch changes require user consent.
+- Destructive ops forbidden unless explicit (`reset --hard`, `clean`, `restore`, `rm`, …).
+- Don’t delete/rename unexpected stuff; stop + ask.
+- No repo-wide S/R scripts; keep edits small/reviewable.
+- Avoid manual `git stash`; if Git auto-stashes during pull/rebase, that’s fine (hint, not hard guardrail).
+- If user types a command (“pull and push”), that’s consent for that command.
+- No amend unless asked.
+- Big review: `git --no-pager diff --color=never`.
+- Multi-agent: check `git status/diff` before edits; ship small commits.
+
+## Language/Stack Notes
+
+- Swift: use workspace helper/daemon; validate `swift build` + tests; keep concurrency attrs right.
+- TypeScript: use repo PM; keep files small; follow existing patterns.
+
+## macOS Permissions / Signing (TCC)
+
+- Never re-sign / ad-hoc sign / change bundle ID as “debug” without explicit ok (can mess TCC).

+# Changelog
+
+## v0.5.6 (2026-03-10)
+
+### Fixed
+
+- Dictionary: Persist merged character-dictionary MRU state as soon as a new retained set is built so revisits do not get dropped if later Yomitan import work fails, and skip merged dictionary rebuilds for reorder-only revisits when the retained anime set itself has not changed.
+- Startup: Fixed early Electron startup writing config and user data under a lowercase `~/.config/subminer` path instead of the canonical `~/.config/SubMiner` directory.
+- Overlay: Kept JLPT underline colors stable during Yomitan hover and selection states, even when tokens also use known, N+1, name-match, or frequency styling.
+
+## v0.5.5 (2026-03-09)
+
+### Changed
+
+- Overlay: Added `f` as the default overlay fullscreen toggle and changed the default AniSkip intro-jump key to `Tab`.
+- Dictionary: Aligned AniList character dictionary generation more closely with the upstream reference by preserving duplicate shared names across characters, skipping characters without native Japanese names, restoring richer character info fields, and using upstream-style role mapping plus hint-aware kanji readings.
+- Startup: Ordered startup OSD messages so tokenization loads first, annotation loading appears next if still pending, and character dictionary sync progress waits until annotation loading finishes.
+- Dictionary: Added a visible startup OSD step for merged character-dictionary building so long rebuilds show progress before the later import/upload phase.
+
+### Fixed
+
+- Dictionary: Fixed AniList media guessing for character dictionary auto-sync by using filename-only `guessit` input and preserving multi-part guessit titles instead of truncating them to the first segment.
+- Dictionary: Refresh the current subtitle after character dictionary auto-sync completes so newly imported character names highlight on the active line instead of waiting for the next subtitle change.
+- Dictionary: Show character dictionary auto-sync progress on the mpv OSD without sending desktop notifications.
+- Dictionary: Keep character dictionary auto-sync non-blocking during startup by letting snapshot/build work run in parallel and delaying only the Yomitan import/settings phase until current-media tokenization is already ready.
+- Overlay: Fixed visible overlay keyboard handling so pressing `Tab` still reaches mpv and triggers the default AniSkip skip-intro binding while the overlay has focus.
+- Plugin: Fix Windows mpv plugin binary override lookup so `SUBMINER_BINARY_PATH` still resolves to `SubMiner.exe` when no AppImage override is set.
+
+## v0.5.3 (2026-03-09)
+
+### Changed
+
+- Release: Publish unsigned Windows `.exe` and `.zip` artifacts directly from release CI instead of routing them through SignPath.
+- Release: Added `bun run build:win:unsigned` for explicit local unsigned Windows packaging.
+
+## v0.5.2 (2026-03-09)
+
+### Internal
+
+- Release: Pinned the Windows SignPath submission workflow to an explicit artifact-configuration slug instead of relying on the SignPath project's default configuration.
+
+## v0.5.1 (2026-03-09)
+
+### Changed
+
+- Launcher: Removed the YouTube subtitle generation mode switch so YouTube playback always preloads subtitles before mpv starts.
+
+### Fixed
+
+- Launcher: Hardened YouTube AI subtitle fixing so fenced SRT output and text-only one-cue-per-block responses can still be applied without losing original cue timing.
+- Launcher: Skipped AniSkip lookup during URL playback and YouTube subtitle-preload playback, limiting AniSkip to local file targets where it can actually resolve anime metadata.
+- Launcher: Keep the background SubMiner process running after a launcher-managed mpv session exits so the next mpv instance can reconnect without restarting the app.
+- Launcher: Reuse prior tokenization readiness after the background app is already warm so reopening a video does not pause again waiting for duplicate warmup completion.
+- Windows: Acquire the app single-instance lock earlier so Windows overlay/video launches reuse the running background SubMiner process instead of booting a second full app and repeating startup warmups.
+
+## v0.3.0 (2026-03-05)
+
+- Added keyboard-driven Yomitan navigation and popup controls, including optional auto-pause.
+- Added subtitle/jump keyboard handling fixes for smoother subtitle playback control.
+- Improved Anki/Yomitan reliability with stronger Yomitan proxy syncing and safer extension refresh logic.
+- Added Subsync `replace` option and deterministic retime naming for subtitle workflows.
+- Moved aniskip resolution to launcher-script options for better control.
+- Tuned tokenizer frequency highlighting filters for improved term visibility.
+- Added release build quality-of-life for CLI publish (`gh`-based clobber upload).
+- Removed docs Plausible integration and cleaned associated tracker settings.
+
+## v0.2.3 (2026-03-02)
+
+- Added performance and tokenization optimizations (faster warmup, persistent MeCab usage, reduced enrichment lookups).
+- Added subtitle controls for no-jump delay shifts.
+- Improved subtitle highlight logic with priority and reliability fixes.
+- Fixed plugin loading behavior to keep OSD visible during startup.
+- Fixed Jellyfin remote resume behavior and improved autoplay/tokenization interaction.
+- Updated startup flow to load dictionaries asynchronously and unblock first tokenization sooner.
+
+## v0.2.2 (2026-03-01)
+
+- Improved subtitle highlighting reliability for frequency modes.
+- Fixed Jellyfin misc info formatting cleanup.
+- Version bump maintenance for 0.2.2.
+
+## v0.2.1 (2026-03-01)
+
+- Delivered Jellyfin and Subsync fixes from release patch cycle.
+- Version bump maintenance for 0.2.1.
+
+## v0.2.0 (2026-03-01)
+
+- Added task-related release work for the overlay 2.0 cycle.

 SubMiner is an Electron overlay that sits on top of mpv. It turns your video player into a full sentence-mining workstation:
 
-- **Hover to look up** — Yomitan dictionary popups directly on subtitles
-- **Keyboard-driven lookup mode** — Navigate token-by-token, keep lookup open across tokens, and control popup scrolling/audio/mining without leaving the overlay
-- **One-key mining** — Creates Anki cards with sentence, audio, screenshot, and translation
-- **Instant auto-enrichment** — Optional local AnkiConnect proxy enriches new Yomitan cards immediately
-- **Reading annotations** — Combines N+1 targeting, frequency-dictionary highlighting, and JLPT underlining while you read
-- **Hover-aware playback** — By default, hovering subtitle text pauses mpv and resumes on mouse leave (`subtitleStyle.autoPauseVideoOnHover`)
+- **Look up words as you watch** — Yomitan dictionary popups on hover or keyboard-driven token-by-token navigation
+- **One-key Anki mining** — Creates cards with sentence, audio, screenshot, and translation; optional local AnkiConnect proxy auto-enriches Yomitan cards instantly
+- **Reading annotations** — N+1 targeting, frequency-dictionary highlighting, JLPT underlining, and character name dictionary for anime/manga proper nouns
 - **Subtitle tools** — Download from Jimaku, sync with alass/ffsubsync
-- **Immersion tracking** — SQLite-powered stats on your watch time and mining activity
-- **Custom texthooker page** — Built-in custom texthooker page and websocket, no extra setup
-- **Jellyfin integration** — Remote playback setup, cast device mode, and direct playback launch
-- **AniList progress** — Track episode completion and push watching progress automatically
+- **Jellyfin & AniList integration** — Remote playback, cast device mode, and automatic episode progress tracking
+- **Texthooker & API** — Built-in texthooker page and annotated websocket feed for external clients

-**From source** or **macOS** — see the [installation guide](https://docs.subminer.moe/installation#from-source).
+**macOS (DMG/ZIP):** download the latest packaged build from [GitHub Releases](https://github.com/ksyasuda/SubMiner/releases/latest) and drag `SubMiner.app` into `/Applications`.
 
-### 2. Install the mpv plugin and configuration file
+**Windows (Installer/ZIP):** download the latest `SubMiner-<version>.exe` installer or portable `.zip` from [GitHub Releases](https://github.com/ksyasuda/SubMiner/releases/latest). Keep `mpv` installed and available on `PATH`.
+
+**From source** — initialize submodules first (`git submodule update --init --recursive`). Bundled Yomitan is built from the `vendor/subminer-yomitan` submodule into `build/yomitan` during `bun run build`, so source builds only need Bun for the JS toolchain. Packaged macOS and Windows installs do not require Bun. Windows installer builds go through `electron-builder`; its bundled `app-builder-lib` NSIS templates already use the third-party `WinShell` plugin for shortcut AppUserModelID assignment, and the `WinShell.dll` binary is supplied by electron-builder's cached `nsis-resources` bundle, so `bun run build:win` does not need a separate repo-local plugin install step. Full install guide: [docs.subminer.moe/installation#from-source](https://docs.subminer.moe/installation#from-source).

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+
+Add a config option under `texthooker` to launch the built-in texthooker server automatically when SubMiner starts.
+
+Scope:
+
+- Add `texthooker.launchAtStartup`.
+- Default to `true`.
+- Start the existing texthooker server during normal app startup when enabled.
+- Keep `texthooker.openBrowser` as separate behavior.

+
+<!-- AC:BEGIN -->

+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Added `texthooker.launchAtStartup` with a default of `true`, wired it through config defaults/validation/template generation, and started the existing texthooker server during app-ready startup without coupling it to browser auto-open behavior.
+
+Also added regression coverage for config parsing/template output and app-ready dependency wiring, then regenerated the checked-in config example artifacts.

+
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+
+- [x] #1 Character fetch reads AniList alternative character names needed for lookup coverage
+- [x] #2 Generated term banks include alias-derived terms for subtitle lookups like シャドウ
+- [x] #3 Regression coverage proves alternative-name indexing works end to end
+<!-- AC:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Character dictionary generation now requests AniList `name.alternative`, indexes those aliases as term candidates, and expands mixed aliases like `Minoru Kagenou (影野ミノル)` into usable outer/inner variants. Also extended kana alias synthesis so the AniList alias `Shadow` emits `シャドウ`, which matches the subtitle token the user hit in The Eminence in Shadow.
+
+Bumped the character-dictionary snapshot format to invalidate stale cached snapshots, and updated merged-dictionary rebuilds to refresh invalid snapshots before composing the ZIP so old cache files do not hard-fail the merge path.
+
+Verified with `bun test src/main/character-dictionary-runtime.test.ts` and `bun run tsc --noEmit`.

+
+Make the packaged Linux no-arg launch path behave like a quiet background start instead of surfacing startup-only noise.
+
+Scope:
+
+- Treat default background entry launches as implicit `--start --background`.
+- Keep the `--password-store` diagnostic out of normal startup output.
+- Suppress known startup-only `node:sqlite` and `lsfg-vk` warnings for the entry/background launch path.
+- Avoid noisy protocol-registration warnings during normal startup when registration is unsupported.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+
+- [x] #1 Initial background launch reaches the start path without logging `No running instance. Use --start to launch the app.`
+- [x] #2 Default startup no longer emits the `Applied --password-store gnome-libsecret` line at normal log levels.
+- [x] #3 Entry/background launch sanitization suppresses the observed `ExperimentalWarning: SQLite...` and `lsfg-vk ... unsupported configuration version` startup noise.
+- [x] #4 Regression coverage documents the new startup behavior.
+<!-- AC:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+
+Normalized no-arg/password-store-only entry launches to append implicit `--start --background`, and upgraded `--background`-only entry launches to include `--start`.
+
+Applied shared entry env sanitization before loading the main process so default startup strips the `lsfg-vk` Vulkan layer and sets `NODE_NO_WARNINGS=1`; background children keep the same sanitized env.
+
+Downgraded startup-only protocol-registration failure logging to debug, and routed the Linux password-store diagnostic through the scoped debug logger instead of raw console output.
+
+Verification:
+
+- `bun test src/main-entry-runtime.test.ts src/main/runtime/anilist-setup-protocol.test.ts src/main/runtime/anilist-setup-protocol-main-deps.test.ts`
+- `bun run test:fast`
+
+Note: the final `node --experimental-sqlite --test dist/main/runtime/registry.test.js` step in `bun run test:fast` still prints Node's own experimental SQLite warning because that test command explicitly enables the feature flag outside the app entrypoint.
+
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Default packaged startup is now quiet and behaves like an implicit `--start --background` launch.

+- No-arg AppImage entry launches now append `--start --background`, and `--background`-only launches append the missing `--start`.
+- Entry/background startup sanitization now suppresses the observed `lsfg-vk` and `node:sqlite` warnings on the app launch path.

+- [x] #1 Regular `websocket.enabled: "auto"` behavior remains unchanged and still skips the regular websocket when `mpv_websocket` is installed.
+- [x] #2 A separate `annotationWebsocket` config controls an independent annotated websocket with default port `6678`.
+- [x] #3 Bundled texthooker is pointed at the annotation websocket when it is enabled.

+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Added `annotationWebsocket.enabled`/`annotationWebsocket.port` with defaults of `true`/`6678`, started that websocket independently from the regular auto-managed websocket, and injected the bundled texthooker websocket URL so it connects to the annotation feed by default.
+
+Also added focused regression coverage and regenerated the checked-in config examples.

Keep the lightweight texthooker UX, but preserve token metadata for hover, match overlay color-precedence rules across known/N+1/name/frequency/JLPT, expose name-match highlighting as a toggle, and emit a structured annotation payload on the dedicated websocket so non-SubMiner clients can treat it as an API.

+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Extended the dedicated annotation websocket payload to ship `version`, plain `text`, rendered `sentence`, and structured `tokens` metadata while keeping backward-compatible `sentence` consumers working. Updated the vendored texthooker to preserve hover metadata attrs, follow overlay color precedence for known/N+1/name/frequency/JLPT annotations, add a character-name highlight toggle plus standalone-web dictionary note, and render lightweight hover labels for frequency/JLPT metadata. Added focused regression coverage and rebuilt both the vendored texthooker bundle and SubMiner.

+<!-- SECTION:PLAN:END -->

+## Implementation Notes

+
+Initial triage: `ipc-command.ts` emits raw `${sid}`/`${secondary-sid}` placeholder strings, and `showMpvOsdRuntime` sends `show-text` via mpv client API without enabling property expansion.
+
+User approved implementation plan on 2026-03-07.
+
+Implementation: proxy mpv command OSD now supports an async resolver so subtitle track cycling can show human-readable labels instead of raw `${sid}` placeholders.
+
+Implementation: `showMpvOsdRuntime` now prefixes placeholder-based messages with mpv client-api `expand-properties`, which fixes raw `${...}` OSD output for subtitle delay/position messages.
+
+Testing: `bun test src/core/services/ipc-command.test.ts src/core/services/mpv-control.test.ts src/main/runtime/mpv-proxy-osd.test.ts src/main/runtime/ipc-mpv-command-main-deps.test.ts src/main/runtime/ipc-bridge-actions.test.ts src/main/runtime/ipc-bridge-actions-main-deps.test.ts src/main/runtime/composers/ipc-runtime-composer.test.ts` passed.

+
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Fixed subtitle-cycle OSD handling for the default J/Shift+J keybindings. The IPC mpv command path now supports resolving proxy OSD text asynchronously, and the main-runtime resolver reads mpv `track-list` state so primary and secondary subtitle cycling show human-readable track labels instead of raw `${sid}` / `${secondary-sid}` placeholders.
+
+Also fixed the lower-level mpv OSD transport so placeholder-based `show-text` messages sent through the client API opt into `expand-properties`. That preserves existing template-based OSD messages like subtitle delay and subtitle position without leaking the raw `${...}` syntax.
+
+Added regression coverage for the async proxy OSD path, the placeholder-expansion `showMpvOsdRuntime` path, and the runtime subtitle-track label resolver. Verification run: `bun x tsc --noEmit`; focused mpv/IPC tests; and the maintained `bun run test:core:src` lane (423 pass, 6 skip, 0 fail).

+
+Validated Claude's PR #15 review summary against the current branch and applied the actionable fixes. In `.github/workflows/release.yml`, the release `quality-gate` job now restores the dependency cache before installation, no longer installs twice, and runs `bun run typecheck` before the fast test suite to match CI expectations. In `.gitmodules`, removed the duplicate `vendor/yomitan-jlpt-vocab` stanza with the conflicting duplicate path. Through Backlog MCP, updated `TASK-101` references from an absolute local path to repo-relative paths so the task metadata is portable across contributors.
+
+Verification: `git diff --check`, `git config -f .gitmodules --get-regexp '^submodule\..*\.path$'`, `bun run typecheck`, and `bun run test:fast` all passed. `bun run format:check` still fails on many pre-existing unrelated files already present on the branch, including multiple backlog task files and existing source/docs files; this review patch did not attempt a repo-wide formatting sweep.

+
+GitHub Actions run 22810400921 failed in job build-test-audit, step `Test suite (source)`, with a single failing test: `JLPT CSS rules use underline-only styling in renderer stylesheet` in src/renderer/subtitle-render.test.ts.
+
+Reproduced the failing test locally with `bun test src/renderer/subtitle-render.test.ts`. The failure was a brittle stylesheet assertion, not a renderer behavior regression.
+
+Updated the renderer stylesheet test helper to split selectors safely across `:is(...)` commas and normalize multiline selector whitespace, then switched the failing hover/JLPT assertions to inspect extracted rule blocks instead of matching the entire CSS file text.
+
+Verification passed with `bun test src/renderer/subtitle-render.test.ts` and `bun run test`.
+
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Investigated GitHub Actions CI run `22810400921` for PR #15 and confirmed the only failing job was `build-test-audit`, step `Test suite (source)`, with a single failure in `src/renderer/subtitle-render.test.ts` (`JLPT CSS rules use underline-only styling in renderer stylesheet`).
+
+The renderer CSS itself was still correct; the regression was in the test helper. `extractClassBlock` was splitting selector lists on every comma, which breaks selectors containing `:is(...)`, and the affected assertions fell back to brittle whole-file regex matching against a multiline selector. Fixed the test by teaching the helper to split selectors only at top-level commas, normalizing selector whitespace around multiline `:not(...)` / `:is(...)` clauses, and asserting on extracted rule blocks for the plain-word hover and JLPT-only hover/selection rules.
+
+Verification: `bun test src/renderer/subtitle-render.test.ts` passed, and `bun run test` passed end to end (the same fast lane that failed in CI).

+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+
+The repository already had Windows packaging configuration (`build:win`, NSIS include script, Windows helper asset packaging), but the release workflow still built Linux and macOS only.
+
+Added a `build-windows` job to `.github/workflows/release.yml` that runs on `windows-latest`, validates required SignPath secrets, builds unsigned Windows artifacts, uploads them with `actions/upload-artifact@v4`, and then calls the official `signpath/github-action-submit-signing-request@v2` action to retrieve signed outputs.
+
+Checked in `build/signpath-windows-artifact-config.xml` as the source-of-truth artifact configuration for SignPath. It signs the top-level NSIS installer EXE and deep-signs `.exe` and `.dll` files inside the portable ZIP artifact.
+
+Updated the release aggregation job to download the signed Windows artifacts and added a Windows install section to the generated GitHub release body.
+
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Windows release publishing is now wired into the tag-driven workflow. `.github/workflows/release.yml` builds Windows artifacts on `windows-latest`, submits them to SignPath using the official GitHub action, and publishes the signed `.exe` and `.zip` outputs alongside the Linux and macOS artifacts. The workflow now requests the additional `actions: read` permission required by the SignPath GitHub integration, and the generated release notes now include Windows installation steps.
+
+The checked-in `build/signpath-windows-artifact-config.xml` file defines the SignPath artifact structure expected by the workflow artifact ZIP: sign the top-level `SubMiner-*.exe` installer and deep-sign `.exe` and `.dll` files inside `SubMiner-*.zip`.
+
+Verification: workflow/static changes were checked with `git diff --check` on the touched files. Actual signing requires configured SignPath secrets and a matching artifact configuration in your SignPath project.

+3. Patch the Publish Release step in .github/workflows/release.yml to remove the invalid gh CLI usage while preserving non-prerelease release creation/update behavior.
+4. Re-run the targeted regression test and any relevant lightweight verification, then record results in task notes.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+
+Identified root cause from GitHub Actions run 22812335927: Publish Release failed with `accepts 1 arg(s), received 2` because the workflow passed a value to gh's boolean prerelease flag.
+
+Added a workflow comment clarifying that omitting the prerelease flag keeps normal releases as non-prerelease releases.
+
+Added src/release-workflow.test.ts and wired it into `bun run test:fast` so CI catches the invalid workflow shape before the next tag.
+
+Verification: `bun test src/release-workflow.test.ts`, `bun run typecheck`, and `bun run test:fast` all passed locally.
+
+Code-review pass found no issues; remaining caveat is that prerelease tag semantics are still not modeled for tags like `v1.0.0-beta.1`, which is outside this fix scope.
+
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Fixed the GitHub Actions release publish step so tagged releases no longer fail on invalid gh CLI usage. The workflow now omits the prerelease flag when creating or editing normal releases, which preserves existing non-prerelease behavior and avoids the `accepts 1 arg(s), received 2` failure seen in run 22812335927.
+
+Added a small regression test that reads `.github/workflows/release.yml` and asserts the publish step does not set the prerelease flag, then included that test in `bun run test:fast` so the main verification lane catches this class of workflow regression before the next release.
+
+Validation run locally: `bun test src/release-workflow.test.ts`, `bun run typecheck`, and `bun run test:fast`. Residual risk: prerelease-tag semantics remain unchanged for tags such as `v1.0.0-beta.1`; this fix is intentionally scoped to restoring normal tagged release publication.

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+
+Allow SubMiner to follow subtitles from a separate Jellyfin client session, such as a TV app, without requiring local mpv playback. The feature should fetch the active subtitle stream from Jellyfin, map the remote playback position to subtitle cues, and feed the existing subtitle tokenization plus annotated texthooker websocket pipeline so texthooker-only mode can be used while watching on another device.
+
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+
+- [ ] #1 User can target a remote Jellyfin session and stream its current subtitle cue into SubMiner's existing subtitle-processing pipeline without launching local Jellyfin playback in mpv.
+- [ ] #2 Texthooker-only mode can display subtitle updates from the tracked remote Jellyfin session through the existing annotation websocket feed.
+- [ ] #3 Remote session changes are handled safely: item changes, subtitle-track changes, pause/seek/stop, and session disconnects clear or refresh subtitle state without crashing.
+- [ ] #4 The feature degrades clearly when the remote session has no usable text subtitle stream or uses an unsupported subtitle format.
+- [ ] #5 Automated tests cover session tracking, subtitle cue selection, and feed integration; user-facing docs/config docs are updated.

+
+Reproduced against https://www.youtube.com/watch?v=MXzQRLmN9hE with yt-dlp --list-subs: manual zh/en/ja/ko subtitle tracks are available from YouTube.
+
+Adjusted launcher YouTube orchestration so detected manual subtitle tracks suppress whisper generation but are no longer materialized as external subtitle files. SubMiner now relies on the native YouTube/mpv subtitle tracks for those languages.
+
+Added orchestration tests covering the manual-track reuse plan and ran a direct runtime probe against MXzQRLmN9hE. Probe result: primary/secondary native tracks detected, no external subtitle aliases emitted, output directory remained empty.

+
+Improve the release changelog workflow so changelog fragments are reliable, release output is more readable, and pull requests get early feedback when changelog metadata is missing or malformed.
+
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+
+- [x] #1 `scripts/build-changelog.ts` ignores non-fragment files in `changes/` and validates fragment structure before generating changelog output.
+- [x] #2 Generated `CHANGELOG.md` and `release/release-notes.md` group public changes into readable sections instead of a flat bullet list.

+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+
+1. Add failing tests for changelog fragment discovery, structured fragment parsing/rendering, release-note output, and CI workflow expectations.
+2. Update scripts/build-changelog.ts to ignore non-fragment files, parse fragment metadata, group generated output by change type, add lint/PR-check commands, and simplify output paths to repo-local artifacts.
+3. Update CI and PR workflow files to run changelog validation on pull requests with an explicit skip path, and keep release workflow using committed changelog output.
+4. Refresh changes/README.md, docs/RELEASING.md, and any PR template text so contributors know how to write fragments and when opt-out is allowed.
+5. Run targeted tests and changelog commands, then record results and finalize the task.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+
+Implemented structured changelog fragments with required `type` and `area` metadata; `changes/README.md` is now ignored by the generator and verified by regression tests.
+
+Added `changelog:lint` and `changelog:pr-check`, plus PR CI enforcement with `skip-changelog` opt-out. PR check now reads git name-status output so deleted fragment files do not satisfy the requirement.
+
+Changed generated changelog/release notes output to grouped sections (`Added`, `Changed`, `Fixed`, etc.) and simplified release notes to highlights + install/assets pointers.
+
+Kept changelog output repo-local. This aligns with existing repo direction where docs updates happen in the sibling docs repo explicitly rather than implicit local writes from app-repo generators.
+
+Verification: `bun test scripts/build-changelog.test.ts src/ci-workflow.test.ts src/release-workflow.test.ts` passed; `bun run typecheck` passed; `bun run changelog:lint` passed. `bun run test:fast` still fails in unrelated existing `src/core/services/subsync.test.ts` cases (`runSubsyncManual keeps internal alass source file alive until sync finishes`, `runSubsyncManual resolves string sid values from mpv stream properties`).
+
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Hardened the changelog workflow end-to-end. `scripts/build-changelog.ts` now ignores helper files like `changes/README.md`, requires structured fragment metadata (`type` + `area`), groups generated release sections by change type, and emits shorter release notes focused on highlights plus install/assets pointers. Added explicit `changelog:lint` and `changelog:pr-check` commands, with PR validation based on git name-status so deleted fragment files do not satisfy the fragment requirement.
+
+Updated contributor-facing workflow docs in `changes/README.md`, `docs/RELEASING.md`, and a new PR template so authors know to add a fragment or apply the `skip-changelog` label. CI now runs fragment linting on every run and enforces fragment presence on pull requests. Added regression coverage in `scripts/build-changelog.test.ts` and a new `src/ci-workflow.test.ts` to lock the workflow contract.
+
+Verification completed: `bun test scripts/build-changelog.test.ts src/ci-workflow.test.ts src/release-workflow.test.ts`, `bun run typecheck`, and `bun run changelog:lint` all passed. A broader `bun run test:fast` run still fails in unrelated existing `src/core/services/subsync.test.ts` cases outside the changelog/workflow scope.

+<!-- SECTION:DESCRIPTION:BEGIN -->
+
+Simplify launcher YouTube playback by removing the configurable subtitle generation mode. For YouTube targets, the launcher should treat subtitle generation/loading as the canonical behavior instead of supporting off/preprocess/automatic branches. This change should remove the unreliable automatic/background path and the mode concept from config/CLI/env/docs, while preserving the core YouTube subtitle generation pipeline and mpv loading flow.
+
+<!-- SECTION:DESCRIPTION:END -->

+2. Update playback orchestration so YouTube targets always run subtitle generation/loading before mpv startup and delete the background automatic path.
+3. Adjust mpv YouTube URL argument construction to no longer branch on mode while preserving subtitle/audio language behavior and preloaded subtitle file injection.
+4. Add/modify tests first to cover removed mode parsing and the single YouTube preload flow, then update config/docs/examples to match the simplified interface.
+5. Run focused launcher/config tests plus typecheck, then summarize any remaining gaps.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->

+
+Verification: bun test launcher/config-domain-parsers.test.ts launcher/parse-args.test.ts launcher/mpv.test.ts launcher/main.test.ts src/config/config.test.ts; bun run test:config:src; bun run typecheck.
+
+Broader repo checks still show pre-existing issues outside this change: bun run test:launcher:unit:src fails in launcher/aniskip-metadata.test.ts (MAL id assertion), and format scope check reports unrelated existing files launcher/youtube/orchestrator.ts, scripts/build-changelog.test.ts, scripts/build-changelog.ts.

+<!-- SECTION:NOTES:END -->
+
+## Final Summary

+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Removed the launcher YouTube subtitle generation mode surface so YouTube playback now always runs the subtitle generation pipeline before starting mpv. The launcher no longer accepts youtubeSubgen.mode from shared config, CLI, or env normalization, and the old automatic/background loading path has been deleted from playback.
+
+Updated mpv YouTube startup options to keep manual subtitle discovery enabled without requesting auto subtitles, and refreshed user-facing config/docs to describe a single YouTube subtitle generation flow.

The launcher now skips AniSkip before mpv launch, and the mpv plugin now also refuses AniSkip lookups for remote URL media during file-loaded, overlay-start, or later refresh triggers. Added regression coverage in both launcher/mpv.test.ts and scripts/test-plugin-start-gate.lua, plus a changelog fragment. Wider `bun run test:launcher:unit:src` is still blocked by the unrelated existing launcher/aniskip-metadata.test.ts MAL-id failure.

+2. Update launcher teardown so normal mpv-session cleanup only stops mpv/helper children and preserves the background SubMiner process for future reconnects.
+3. Run the focused launcher tests and smoke coverage for the affected behavior, then record results in the task.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+
+Split launcher cleanup so normal mpv-session shutdown no longer sends `--stop` to SubMiner or SIGTERM to the tracked overlay process. Added `cleanupPlaybackSession()` for mpv/helper-child cleanup only, and switched playback finalization to use it.
+
+Updated launcher smoke coverage to assert the background app stays alive after mpv exits, and added a focused unit regression for the new cleanup path.
+
+Validation: `bun test launcher/mpv.test.ts launcher/smoke.e2e.test.ts` passed; `bun run typecheck` passed. `bun run test:launcher:unit:src` still reports an unrelated pre-existing failure in `launcher/aniskip-metadata.test.ts`.
+
+Added changelog fragment `changes/task-130.md` for the launcher fix and verified it with `bun run changelog:lint`.
+
+User verified the bug still reproduces when closing playback with `q`. Root cause narrowed further: the mpv plugin `plugin/subminer/lifecycle.lua` calls `process.stop_overlay()` on mpv `shutdown`, which still sends SubMiner `--stop` even after launcher cleanup was fixed.
+
+Patched the remaining stop path in `plugin/subminer/lifecycle.lua`: mpv `shutdown` no longer calls `process.stop_overlay()`. Pressing mpv `q` should now preserve the background app and only tear down the mpv session.
+
+Validation update: `lua scripts/test-plugin-start-gate.lua` passed after adding a shutdown regression, and `bun test launcher/mpv.test.ts launcher/smoke.e2e.test.ts` still passed.
+
+Fixed a second-instance reconnect bug in `src/core/services/cli-command.ts`: `--start` on an already-initialized running instance now still updates the MPV socket path and reconnects the MPV client instead of treating the command as a no-op. This keeps the already-warmed background app reusable for later mpv launches.
+
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Kept the background SubMiner process reusable across both mpv shutdown and later reconnects. The first fix separated launcher playback cleanup from full app shutdown. The second fix removed the mpv plugin `shutdown` stop call so default mpv `q` no longer sends SubMiner `--stop`. The third fix corrected second-instance CLI handling so `--start` on an already-running, already-initialized instance still reconnects MPV instead of being ignored.
+
+Net effect: background SubMiner can stay alive, keep its warm state, and reconnect to later mpv instances without rerunning startup/warmup work in a fresh app instance.
+
+Coverage now includes: launcher playback cleanup (`launcher/mpv.test.ts`), launcher smoke reconnect/keep-alive flow (`launcher/smoke.e2e.test.ts`), mpv plugin shutdown preservation (`scripts/test-plugin-start-gate.lua`), and second-instance start/reconnect behavior (`src/core/services/cli-command.test.ts`).

+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+
+When SubMiner is already running in the background and mpv is launched from the launcher or mpv plugin, the live app should reuse startup tokenization warmup state instead of re-entering the Yomitan/tokenization/annotation warmup path on first overlay use.
+
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+
+- [x] #1 Background startup tokenization warmup is recorded in the runtime state used by later mpv/tokenization flows.
+- [x] #2 Launching mpv from the launcher or plugin against an already-running background app does not re-run duplicate Yomitan/tokenization annotation warmup work in the live process.
+- [x] #3 Regression tests cover the warmed-background path and protect against re-entering duplicate warmup work.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+
+1. Add a regression test covering the case where background startup warmups already completed and a later tokenize call must not re-enter Yomitan/MeCab/dictionary warmups.
+2. Update mpv tokenization warmup composition so startup background warmups and on-demand tokenization share the same completion state.
+3. Run the focused composer/runtime tests and update acceptance criteria/notes with results.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+
+Root-cause hypothesis: startup background warmups and on-demand tokenization warmups use separate state, so later mpv launch can re-enter warmup bookkeeping even though background startup already warmed dependencies.
+
+Implemented shared warmup state between startup background warmups and on-demand tokenization warmups by forwarding scheduled Yomitan/tokenization promises into the mpv runtime composer. Added regression coverage for the warmed-background path. Verified with `bun run test:fast` plus focused composer/startup warmup tests.
+
+Follow-up root cause from live retest: second mpv open could still pause on the startup gate because the runtime only treated full background tokenization warmup completion as reusable readiness. In practice, first-file tokenization could already be ready while slower dictionary prewarm work was still finishing, so reopening a video waited on duplicate warmup completion even though annotations were already usable.
+
+Adjusted `src/main/runtime/composers/mpv-runtime-composer.ts` so autoplay reuse keys off a separate playback-ready latch. The latch flips true either when background warmups fully cover tokenization or when `onTokenizationReady` fires for a real subtitle line. `src/main.ts` already uses `isTokenizationWarmupReady()` to fast-signal `subminer-autoplay-ready` on a fresh media-path change, so reopened videos can now resume immediately once tokenization has succeeded once in the persistent app.
+
+Validation update: `bun test src/core/services/cli-command.test.ts src/main/runtime/mpv-main-event-actions.test.ts src/main/runtime/composers/mpv-runtime-composer.test.ts launcher/mpv.test.ts launcher/smoke.e2e.test.ts` passed, `lua scripts/test-plugin-start-gate.lua` passed, and `bun run typecheck` passed.
+
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Background startup tokenization warmups now feed the same in-memory warmup state used by later mpv tokenization. When the app is already running and warmed in the background, launcher/plugin-driven mpv startup reuses that state instead of re-entering Yomitan/tokenization annotation warmups. Added a regression test for the warmed-background path and verified with `bun run test:fast`.
+
+A later follow-up fixed the remaining second-open delay: autoplay reuse no longer waits for the entire background dictionary warmup pipeline to finish. After the persistent app has produced one tokenization-ready event, later mpv reconnects reuse that readiness immediately, so reopening the same or another video does not pause again on duplicate warmup bookkeeping.

+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+
+Added `KeyF -> ['cycle', 'fullscreen']` to the built-in overlay keybindings in `src/config/definitions/shared.ts`.
+
+Changed the mpv plugin AniSkip default button key from `y-k` to `TAB` in both the runtime default options and the shipped `plugin/subminer.conf`. The AniSkip OSD hint now also falls back to `TAB` when no explicit key is configured.
+
+Adjusted `plugin/subminer/ui.lua` fallback registration so the legacy `y-k` binding is only added for custom non-default AniSkip bindings, instead of always shadowing the new default.
+
+Extended regression coverage:
+
+- `src/config/definitions/domain-registry.test.ts` now asserts the default fullscreen binding on `KeyF`.
+- `scripts/test-plugin-start-gate.lua` now isolates plugin runs correctly, records keybinding/observer registration, and asserts the default AniSkip keybinding/prompt behavior for `TAB`.

+<!-- SECTION:NOTES:END -->

+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Default overlay playback now has an easier fullscreen toggle on `f`, and AniSkip's default intro-end jump now uses `Tab`. The mpv plugin hint text and registration logic were updated to match the new default, while keeping legacy `y-k` fallback behavior limited to custom non-default bindings.
+
+Regression coverage was added for both defaults, and the plugin test harness now resets plugin bootstrap state between scenarios so keybinding assertions can run reliably.

+<!-- SECTION:PLAN:END -->

+## Implementation Notes

+
+Extended the base window tracker with optional focus-state callbacks/getters and wired initializeOverlayRuntime to re-sync overlay shortcuts whenever tracker focus changes.
+
+Updated the macOS helper/tracker contract to return geometry plus frontmost/focused state for the tracked mpv process and added parser coverage for focused and unfocused output.
+
+Verified with `bun x tsc -p tsconfig.json --noEmit`, targeted shortcut/tracker tests, and `bun run test:core:src` (439 passing).
+
+No user-facing config or documentation surface changed, so no docs update was required for this fix.
+
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Fixed the macOS background shortcut interception bug by gating SubMiner's global overlay shortcuts on tracked mpv focus instead of overlay-runtime initialization alone. The macOS window helper now reports whether the tracked mpv process is frontmost, the tracker exposes focus change callbacks, and overlay shortcut synchronization re-runs when that focus state flips so `Ctrl+C`/`Ctrl+V` and similar shortcuts are no longer captured while mpv is in the background.
+
+The change keeps existing non-macOS shortcut behavior unchanged. Added regression coverage for the activation decision, tracker focus-change re-sync, and macOS helper output parsing. Verification: `bun x tsc -p tsconfig.json --noEmit`, targeted shortcut/tracker tests, and `bun run test:core:src` (439 passing).

+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+
+The tag-driven Release workflow currently fails the Windows lane if the SignPath connector returns transient 502 errors during submission, and the tagged build scripts also allow electron-builder to implicitly publish unsigned artifacts before the final release job runs. Harden the workflow so transient SignPath outages get bounded retries and release packaging never auto-publishes unsigned assets.
+
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+
+- [ ] #1 Windows release signing retries transient SignPath submission failures within the release workflow before failing the job.
+- [ ] #2 Release packaging scripts disable electron-builder implicit publish so build jobs do not upload unsigned assets on tag builds.
+- [ ] #3 Regression coverage fails if SignPath retry scaffolding or publish suppression is removed.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+
+1. Add a regression test for the release workflow/package script shape covering SignPath retries and `--publish never`.
+2. Patch the Windows release job to retry SignPath submission a bounded number of times and still fail hard if every attempt fails.
+3. Update tagged package build scripts to disable implicit electron-builder publishing during release builds.
+4. Run targeted release-workflow verification and capture any remaining manual release cleanup needed for `v0.5.0`.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+
+The failed Windows signing step in GitHub Actions run `22836585479` was not caused by missing secrets or an artifact-shape mismatch. The SignPath GitHub action retried repeated `502` responses from the SignPath connector for several minutes and then failed the job.
+
+Hardened `.github/workflows/release.yml` by replacing the single SignPath submission with three bounded attempts. The second and third submissions only run if the previous attempt failed, and the job now fails with an explicit rerun message only after all three attempts fail. Signed-artifact upload is keyed to the successful attempt so the release job still consumes the normal `windows` artifact name.
+
+Also fixed a separate release regression exposed by the same run: `electron-builder` was implicitly publishing unsigned release assets during tag builds because the packaging scripts did not set `--publish never` and the workflow injected `GH_TOKEN` into build jobs. Updated the relevant package scripts to pass `--publish never`, removed `GH_TOKEN` from the packaging jobs, and made the final publish step force `--draft=false` when editing an existing tag release so previously-created draft releases get published.
+
+Verification: `bun test src/release-workflow.test.ts`, `bun run typecheck`, and `bun run test:fast` all passed locally after restoring the missing local `libsql` install with `bun install --frozen-lockfile`.

+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Windows release signing is now resilient to transient SignPath connector outages. The release workflow retries the SignPath submission up to three times before failing, and only uploads the signed Windows artifact from the attempt that succeeded.
+
+Release packaging also no longer auto-publishes unsigned assets on tag builds. The `electron-builder` scripts now force `--publish never`, the build jobs no longer pass `GH_TOKEN` into packaging steps, and the final GitHub release publish step explicitly clears draft state when updating an existing tag release.
+
+Validation: `bun test src/release-workflow.test.ts`, `bun run typecheck`, `bun run test:fast`.
+Manual follow-up for the failed `v0.5.0` release: rerun the `Release` workflow after merging/pushing this fix, then clean up the stray draft/untagged release assets created by the failed run if they remain.

+Surface an immediate startup OSD that the character dictionary is being checked, and show a distinct generating message only when the current AniList media actually needs a fresh snapshot build instead of reusing a cached one.
+
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+
+- [x] #1 Auto-sync emits a `checking` progress event before snapshot resolution completes.
+- [x] #2 Auto-sync emits `generating` only for snapshot cache misses and keeps `updating`/`importing` as later phases.
+- [x] #3 Startup OSD sequencing still prioritizes tokenization then annotation loading before buffered dictionary progress.
+<!-- AC:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Character dictionary auto-sync now emits `Checking character dictionary...` as soon as the AniList media is resolved, then emits `Generating character dictionary...` only when the snapshot layer misses and a real rebuild begins. Cached snapshots skip the generating phase and continue straight into the later update/import flow.
+
+Wired those progress callbacks through the character-dictionary runtime boundary, updated the startup OSD sequencer to treat checking/generating as dictionary-progress phases with the same tokenization and annotation precedence, and added regression coverage for cache-hit vs cache-miss behavior plus buffered startup ordering.

+<!-- SECTION:NOTES:BEGIN -->
+
+Extracted visible-overlay input handling into `src/core/services/overlay-window-input.ts` so the `Tab` forwarding decision can be unit tested without loading Electron window primitives.

+3. Update `src/renderer/subtitle-render.test.ts` to verify JLPT hover/selection rules keep the predefined JLPT underline color, then rerun focused and relevant verification commands.
+
+4. Add JLPT-specific `text-decoration-color` overrides directly on child `.c` spans and their hover/selection states, since Yomitan lookup likely paints the decorated child text runs rather than only the parent token span.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Added a renderer regression test that asserts JLPT underline color stays explicit through hover and selection styling.
+
+Updated `src/renderer/style.css` to route JLPT underline color through `--subtitle-jlpt-underline-color` and re-apply it on word/character hover and selection states.
+
+Verification: `bun test src/renderer/subtitle-render.test.ts`, `bun run typecheck`, `bun run test:fast`, `bun run build`, `bun run changelog:lint`, `bunx prettier --check src/renderer/style.css src/renderer/subtitle-render.test.ts changes/jlpt-underline-yomitan.md`. `bun run format:check:src` still fails because of unrelated existing formatting issues in `src/main-entry-runtime.test.ts` and `src/main-entry-runtime.ts`.
+
+User verified the original CSS variable propagation fix did not resolve the live issue; continuing investigation and reopening the task.
+
+Confirmed Chromium was repainting native `text-decoration` underlines with the selected text color; reproduced it in a temporary browser repro and verified that switching the JLPT marker to an inset box-shadow keeps the JLPT color stable during selection.
+
+Replaced the previous native underline approach with a fragment-safe JLPT marker using `box-shadow` plus `box-decoration-break`, then updated stylesheet regression coverage to match the new implementation.
+
+Verification: `bun test src/renderer/subtitle-render.test.ts`, `bunx prettier --check src/renderer/style.css src/renderer/subtitle-render.test.ts`, `bun run typecheck`, `bun run test:fast`, `bun run build`.
+
+User requested reverting the box-shadow marker experiment. Narrowing the fix to preserve native JLPT underline color during Yomitan hover/selection instead of changing the underline rendering method.
+
+Reverted the box-shadow experiment per user request. Restored native JLPT underline styling and added explicit JLPT hover/selection rules so Yomitan lookup states keep the predefined JLPT underline color with `!important`.
+
+Verification after revert/fix: `bun test src/renderer/subtitle-render.test.ts`, `bunx prettier --check src/renderer/style.css src/renderer/subtitle-render.test.ts`, `bun run typecheck`, `bun run build`.
+
+Issue still reproduces specifically during Shift-held Yomitan lookup. Investigating decoration propagation onto child `.c` spans during lookup-triggered hover/selection states.
+
+Added JLPT-specific `text-decoration-color` overrides directly to child `.c` spans and their hover/selection states, in addition to the token span itself, so lookup-triggered decoration painting on child runs keeps the JLPT color.
+
+Verification: `bun test src/renderer/subtitle-render.test.ts`, `bunx prettier --check src/renderer/style.css src/renderer/subtitle-render.test.ts`, `bun run typecheck`, `bun run build`.
+
+Added a final high-specificity combined-state JLPT override after the annotation hover/selection rules. It targets tokens that are both JLPT-tagged and known/N+1/name-match/frequency-highlighted, forcing `text-decoration-color` back to the JLPT variable after the later annotation state blocks.
+
+Verification: `bun test src/renderer/subtitle-render.test.ts`, `bunx prettier --check src/renderer/style.css src/renderer/subtitle-render.test.ts`, `bun run build`.
+
+Switched the JLPT underline from native `text-decoration` to a separate painted underline layer using `background-image` on JLPT tokens. Also changed hover token highlight rules to use `background-color` so the JLPT underline layer survives Shift+Yomitan hover/lookup interactions.
+
+Verification: `bun test src/renderer/subtitle-render.test.ts`, `bunx prettier --check src/renderer/style.css src/renderer/subtitle-render.test.ts`, `bun run build`.
+
+User reports the latest background-image JLPT underline change introduced grey-looking token highlights. Investigating the interaction between the new underline layer and hover background styling.
+
+The background-image underline layer interacts poorly with hover fills and makes highlighted tokens look grey. Switching the separate JLPT underline layer to an inset box-shadow so hover background color and JLPT underline paint can coexist cleanly.
+
+Adjusted the separate JLPT underline layer from `background-image` to inset `box-shadow`. This keeps the underline decoupled from Yomitan hover color while avoiding the grey-looking underline artifact introduced by the background-image approach.
+
+User reports the separate underline layer still disappears/greys out during lookup. Switching strategy again: use a dedicated `border-bottom` JLPT marker instead of box-shadow/background so the underline stays independent from Yomitan hover paint without blending artifacts.
+
+Replaced the separate JLPT underline layer with `border-bottom` plus a small bottom padding. This keeps the underline visually separate from Yomitan hover paint and avoids the disappearing/grey artifact seen with background-image and box-shadow.

+4. Re-run the focused auto-sync suite, then run the relevant broader checks required for handoff.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Added a focused regression in `src/main/runtime/character-dictionary-auto-sync.test.ts` for the `1,2,3,1,4,1` revisit-before-eviction flow. The current MRU auto-sync logic passed: merged builds were `[1]`, `[2,1]`, `[3,2,1]`, `[1,3,2]`, `[4,1,3]`, `[1,4,3]`, so I have not reproduced the reported eviction bug in the in-process auto-sync service yet.
+
+Inspected local cache under `~/.config/SubMiner/character-dictionaries/` and found Little Witch Academia snapshot `anilist-21858.json` already present, so the reported regeneration path was not a snapshot-cache miss. The on-disk `merged.zip` revision (`9251ae23e136`) also differed from `auto-sync-state.json` (`bc16c5b5af17`), indicating a rebuilt merged dictionary artifact could land without the MRU state being persisted.
+
+Fixed `src/main/runtime/character-dictionary-auto-sync.ts` to persist the rebuilt retained-set state immediately after a merged dictionary revision/title is known, before later Yomitan mutation steps. This keeps MRU eviction state aligned even if import/settings work fails after the rebuild artifact is written.
+
+Added regression coverage in `src/main/runtime/character-dictionary-auto-sync.test.ts` for the revisit-before-eviction sequence and for post-build import failure preserving the rebuilt MRU state. Verified with `bun test src/main/runtime/character-dictionary-auto-sync.test.ts src/main/character-dictionary-runtime.test.ts`, `bun run typecheck`, `bun run changelog:lint`, and `bun run test:fast`.

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Keep per-title MRU retention ordering for eviction decisions, but do not rebuild or reimport the merged character dictionary when the retained set membership is unchanged and only the MRU order changes.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Revisiting an anime already inside the retained set updates MRU ordering used for later eviction decisions without rebuilding or reimporting the merged dictionary when retained membership is unchanged.
+- [x] #2 Merged dictionary revisions and contents are stable for the same retained membership regardless of MRU ordering.
+- [x] #3 Adding a new anime that changes retained membership still rebuilds and imports the merged dictionary with the correct eviction behavior.
+- [x] #4 Regression tests cover reorder-only revisits and stable merged revisions for equivalent retained sets.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Add a failing auto-sync regression showing that a revisit which only reorders MRU state should update `activeMediaIds` but skip merged rebuild/import.
+2. Add a runtime-level regression showing `buildMergedDictionary` produces a stable revision for equivalent retained memberships regardless of input order.
+3. Update merged-dictionary build normalization and auto-sync rebuild gating so rebuilds are driven by retained membership changes (or snapshot changes), not MRU reordering alone.
+4. Re-run focused dictionary tests plus the local verification lanes impacted by the change.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Changed `src/main/runtime/character-dictionary-auto-sync.ts` so MRU order still updates in `activeMediaIds`, but merged rebuild/import now keys off retained membership changes rather than order-only reordering. Order-only revisits no longer force a merged ZIP rewrite or Yomitan reimport.
+
+Changed `src/main/character-dictionary-runtime.ts` to canonicalize merged dictionary media ids before building, which makes merged revisions stable for equivalent retained memberships regardless of MRU ordering.
+
+Updated regression coverage in `src/main/runtime/character-dictionary-auto-sync.test.ts` for reorder-only revisits and membership-change rebuilds, and extended `src/main/character-dictionary-runtime.test.ts` to assert stable merged revisions for reordered inputs. Verified with `bun test src/main/runtime/character-dictionary-auto-sync.test.ts src/main/character-dictionary-runtime.test.ts`, `bun run typecheck`, `bun run changelog:lint`, and `bun run test:fast`.

+Added launcher command dispatch (`launcher/commands/dictionary-command.ts`) and wired `launcher/main.ts` to forward `--dictionary` (plus non-default `--log-level`) to app binary.
+
+Added app CLI flag `--dictionary` in parser/help and startup routing (`src/cli/args.ts`, `src/cli/help.ts`).
+
+Added dictionary runtime service (`src/main/character-dictionary-runtime.ts`) that resolves AniList media id from current playback guess, fetches AniList character edges, builds Yomitan-compatible banks/index, writes zip, and caches by AniList id in user data.
+
+Threaded dictionary generation dependency through CLI runtime/context builders and `src/main.ts` context composition so command executes from launcher/app entrypoints.

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+
+Apply the accepted follow-up fixes from Claude's PR review for the AniList character dictionary work: remove dead launcher code, deduplicate video extension handling where practical, and add explicit pacing for AniList character-page requests / character image downloads so the integration stays within AniList rate-limiting expectations.
+
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+
+- [x] #1 Launcher dictionary command no longer contains unreachable dead code after the app handoff.
+- [x] #2 Character dictionary runtime no longer maintains a separate ad hoc video extension list when existing shared extension data can be reused safely.
+- [x] #3 Character dictionary generation spaces outbound AniList-related requests with explicit named delays, and tests cover the pacing behavior and unchanged command forwarding behavior.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+
+1. Add failing tests for dictionary command handoff semantics and dictionary runtime request pacing.
+2. Remove unreachable boolean return path from the launcher dictionary command while preserving call sites.
+3. Reuse the shared launcher video extension set inside the character dictionary runtime with extname normalization, then add named AniList pacing constants for page fetches and character image downloads.
+4. Run targeted tests, then broader relevant test slices, and update acceptance criteria / notes with the validated result.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+
+Added a shared `src/shared/video-extensions.ts` source and rewired both launcher/runtime consumers to remove the duplicated runtime extension list.
+
+Replaced the hardcoded AniList page sleep with a per-generation AniList request pacer (2000ms between API requests) plus 250ms spacing between character image download attempts, including failed image fetches.
+
+Hardened `runDictionaryCommand` so an unexpected return from the `never`-typed app handoff throws immediately instead of silently falling through.
+
+Validated with targeted and adjacent test slices plus `bun run tsc --noEmit`.
+
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Removed the dead post-handoff return from the launcher dictionary command and replaced it with an explicit invariant error if the `never`-typed app handoff ever returns unexpectedly. Extracted video extension data into `src/shared/video-extensions.ts` so the launcher and character dictionary runtime share one source of truth.
+
+Adjusted character dictionary generation to use a per-run AniList request pacer with a conservative 2000ms delay between AniList API calls, and added 250ms spacing between character image download attempts so repeated image fetches are not bursty even when an image URL fails. Added regression coverage for the pacing behavior and the launcher handoff invariant.

+
+<!-- SECTION:NOTES:BEGIN -->
+
+Launcher dictionary subcommand now requires a positional target path (`subminer dictionary <path>` / `dict <path>`) via commander argument wiring in `launcher/config/cli-parser-builder.ts`.
+
+Added `dictionaryTarget` flow in launcher normalization/types and path validation (must be existing local file or directory) in `launcher/config/args-normalizer.ts`.
+
+Launcher dictionary command now forwards `--dictionary --dictionary-target <resolved-path>` to app binary in `launcher/commands/dictionary-command.ts`.
+
+App CLI now parses optional `--dictionary-target` in `src/cli/args.ts`; dictionary handler passes target through to runtime in `src/core/services/cli-command.ts`.
+
+Dictionary runtime now resolves explicit target inputs in `src/main/character-dictionary-runtime.ts`: file target uses file path/title; directory target selects first video file recursively (fallback to directory name), and still falls back to current playback when target is absent.
+
+Updated context/dependency pass-through for dictionary target argument (`src/main.ts`, `src/main/runtime/cli-command-context-main-deps.ts`).
+
+Updated tests/docs for new syntax and forwarding behavior (`launcher/main.test.ts`, `launcher/parse-args.test.ts`, `launcher/commands/command-modules.test.ts`, `src/cli/args.test.ts`, `src/cli/help.test.ts`, `docs/usage.md`, `docs/launcher-script.md`).
+
+Follow-up noise reduction: dictionary commands now opt into lightweight startup path by extending `shouldSkipHeavyStartup` in `src/main.ts` to include `initialArgs.dictionary`. This skips heavy app-ready initialization (mpv client creation/background warmups/overlay bootstrap) for dictionary CLI runs.

 <!-- SECTION:PLAN:BEGIN -->
 
-1. Inventory the current test surface under src/ and launcher/ and compare it to package.json scripts to classify fast, full, slow, and environment-specific suites.
-2. Replace or reduce the brittle hand-maintained allowlist so new maintained tests do not silently miss the standard matrix.
-3. Update contributor docs with the intended fast/full/environment-specific commands.
-4. Verify the new matrix by running the relevant commands and by demonstrating at least one previously omitted runtime/Anki/entry test now belongs to an automated lane.
+1. Update `package.json` to replace the current file-by-file test allowlists with a documented lane matrix: keep `test`/`test:fast` as the quick default lane, add `test:full` for the maintained source test surface, and add `test:env` for slower or environment-specific checks.
+2. Use directory-based discovery for maintained suites so new tests under stable surfaces such as `src/main`, `src/anki-integration`, and `launcher` are not silently omitted by default script maintenance.
+3. Split environment-specific verification into explicit commands for checks such as launcher smoke/plugin coverage and sqlite-gated tests, instead of leaving them undocumented or mixed into the default signal.
+4. Update `README.md` with a contributor-facing testing matrix that explains fast, full, and environment-specific verification, including any prerequisites or expected skip behavior.
+5. Verify the matrix by running representative targeted tests plus the documented lane commands, demonstrating that previously omitted entry/runtime, Anki integration, and main runtime tests now belong to automated commands.
 <!-- SECTION:PLAN:END -->

+
+<!-- SECTION:NOTES:BEGIN -->
+
+Reviewed task context via Backlog MCP plus repo audit. Current package.json test scripts still rely on hand-maintained file allowlists and omit large maintained areas including src/main/runtime, src/anki-integration, and src/main-entry-runtime.test.ts. Preparing an implementation plan and contributor-facing test matrix update before code changes.
+
+Saved detailed implementation plan to docs/plans/2026-03-06-testing-workflow-test-matrix.md and recorded the approved direction in the Backlog task before implementation.
+
+Implemented a lane-based test matrix. Added `scripts/run-test-lane.mjs` so Bun-managed `src/**` and launcher unit lanes discover files automatically while excluding a small explicit Node-only set instead of relying on large hand-maintained allowlists. Added `test:node:compat` for `ipc`, `anki-jimaku-ipc`, `overlay-manager`, `config-validation`, `startup-config`, and `registry` suites, kept `test:env` for launcher smoke/plugin plus SQLite-backed immersion checks, and updated `README.md` with the contributor-facing matrix and exclusions.
+
+Validated the new matrix with `bun run test:fast`, `bun run test:full`, `bun run test:env`, `bun run test:src`, `bun run test:launcher:unit:src`, `bun run test:node:compat`, and targeted `bun test src/core/services/anilist/anilist-updater.test.ts`. Representative previously omitted surfaces now run through automated commands: `src/main-entry-runtime.test.ts` via `test:fast`, `src/anki-integration/anki-connect-proxy.test.ts` via `test:fast`/`test:src`, and `src/main/runtime/registry.test.ts` via `test:node:compat`/`test:full`.

-1. Audit the existing subtitle-sync test surface, especially src/core/services/subsync.test.ts, and decide whether test:subtitle should reuse or regroup that coverage.
-2. Replace the placeholder script with a real automated command and keep the matrix legible alongside TASK-87.1 work.
-3. Update README or related docs so the advertised subtitle verification path matches reality.
-4. Verify both alass and ffsubsync behavior remain covered by the resulting lane.
+Plan of record:
+
+1. Replace the placeholder package-script lane with a real `test:subtitle:src` command that runs the maintained subtitle-sync tests directly (`src/core/services/subsync.test.ts` and `src/subsync/utils.test.ts`), and point `test:subtitle` at that lane instead of build+echo behavior.
+2. Add one focused ffsubsync non-happy-path test in `src/core/services/subsync.test.ts` so the dedicated lane explicitly covers both engines plus failure propagation relevant to current functionality.
+3. Update `README.md` contributor guidance to name `bun run test:subtitle` as the subtitle verification command and explain that it reuses the maintained subsync tests already included in broader core coverage.
+4. Verify the final strategy by running `bun run test:subtitle` and `bun run test:core:src` so the dedicated lane stays aligned with the repository-wide matrix instead of creating a divergent hidden suite.

+
+Reviewed task references and current subtitle verification surface. Existing coverage already lives in `src/core/services/subsync.test.ts` and `src/subsync/utils.test.ts`; `test:subtitle` is still a placeholder build+echo wrapper. The referenced report `docs/reports/2026-02-22-task-100-dead-code-report.md` is not present in the workspace, so planning used the task body plus repository state instead.
+
+Implementation plan written and saved to `docs/plans/2026-03-06-subtitle-sync-verification.md`. Proceeding with execution per the task request.
+
+Replaced the placeholder subtitle lane with `test:subtitle:src` in `package.json`, pointing `test:subtitle` directly at `src/core/services/subsync.test.ts` and `src/subsync/utils.test.ts` instead of build+echo behavior.
+
+Added explicit ffsubsync failure-path coverage in `src/core/services/subsync.test.ts`, asserting non-zero command failures surface detailed `ffsubsync synchronization failed` messaging alongside existing alass coverage.
+
+Updated `README.md` verification guidance to point contributors at `bun run test:subtitle` and explain that the lane reuses the maintained subsync tests already included in `bun run test:core`.
+
+Verification: `bun run test:subtitle` passed (15 tests across 2 files). `bun run test:core:src` also passed (373 pass, 6 skip, 0 fail), confirming the dedicated subtitle lane stays aligned with the broader matrix.
+
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Implemented a real subtitle verification lane by replacing the placeholder `test:subtitle` build+echo flow with a source-level `test:subtitle:src` command that runs the maintained subtitle-sync tests directly from `src/core/services/subsync.test.ts` and `src/subsync/utils.test.ts`. This keeps subtitle verification explicit for contributors while still reusing the same maintained test surface already covered by `test:core`.
+
+Expanded subtitle-sync coverage with an explicit ffsubsync failure-path test so the dedicated lane now exercises both engines plus a user-visible non-happy path. Updated `README.md` to document `bun run test:subtitle` as the contributor-facing subtitle verification command and to explain its relationship to the broader core suite.
+
+Verification run:
+
+- `bun run test:subtitle`
+- `bun run test:core:src`
+
+Notes:
+
+- The task reference `docs/reports/2026-02-22-task-100-dead-code-report.md` was not present in the workspace during execution, so implementation used the task body and live repository state as the source of truth.

 ## Implementation Plan
 
 <!-- SECTION:PLAN:BEGIN -->
 
-1. Confirm which SQLite-backed immersion tests are currently skipped and why in the standard Bun environment.
-2. Establish a reproducible command or lane for the DB-backed cases, or make the unsupported-runtime limitation explicit and actionable.
-3. Document prerequisites and expected behavior for contributors and CI.
-4. Verify at least one persistence/finalization path beyond the seam tests is exercised by the new lane.
+Implementation plan recorded in `docs/plans/2026-03-06-immersion-sqlite-verification.md`.
+
+1. Update `src/core/services/immersion-tracker-service.test.ts` and `src/core/services/immersion-tracker/storage-session.test.ts` so unsupported `node:sqlite` runtimes emit an explicit skip reason instead of a silent top-level skip alias.
+2. Add a dedicated `package.json` SQLite verification lane that runs both immersion persistence suites together under a runtime with `node:sqlite` support, likely via built `dist/**` tests executed by Node.
+3. Wire that lane into `.github/workflows/ci.yml` and `.github/workflows/release.yml` so automated verification includes a real DB-backed persistence/finalization check.
+4. Document the new command, prerequisites, and coverage in `README.md`, including the distinction between Bun's default lane and the reproducible SQLite lane.
+5. Validate the final lane by running the dedicated command and confirming it exercises persistence/finalization behavior beyond the seam-only tests.
+
+Execution adjustment: the reproducible lane uses `node --experimental-sqlite --test ...` because Node 22 exposes `node:sqlite` behind the experimental flag. Running that lane also exposed placeholder-count mismatches in `src/core/services/immersion-tracker/storage.ts`, so the final implementation includes a small SQL placeholder fix required for the new cross-runtime verification path.
+
 <!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+
+Confirmed Bun 1.3.5 lacks `node:test` `t.skip()` support, so explicit unsupported-runtime messaging is surfaced with file-level warnings while the SQLite-backed tests remain conditionally skipped.
+
+Added `test:immersion:sqlite:src`, `test:immersion:sqlite:dist`, and `test:immersion:sqlite` scripts; the source lane now prints explicit warnings when `node:sqlite` is unavailable, and the dist lane runs both SQLite-backed immersion suites under Node with `--experimental-sqlite`.
+
+Wired the dist SQLite lane into `.github/workflows/ci.yml` and `.github/workflows/release.yml` after the bundle build, with explicit `actions/setup-node@v4` provisioning for Node 22.12.0.
+
+Fixed SQL prepared-statement placeholder counts in `src/core/services/immersion-tracker/storage.ts`, which the new Node-backed SQLite lane surfaced immediately.
+
+Verification: `bun run test:immersion:sqlite:src` -> pass with explicit unsupported-runtime warnings and 10 skips under Bun 1.3.5; `bun run test:immersion:sqlite` -> pass with 14/14 tests under Node 22.12.0 + `--experimental-sqlite`.
+
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Added an explicit SQLite-backed immersion verification lane and documented it so persistence-heavy coverage is no longer hidden behind Bun-only skips. `package.json` now exposes source and dist SQLite scripts, the source test files print actionable warnings when `node:sqlite` is unavailable, and `README.md` explains the dedicated contributor command plus its Node 22 `--experimental-sqlite` prerequisite.
+
+Automated verification now includes the new dist lane in both `.github/workflows/ci.yml` and `.github/workflows/release.yml` after build output is available. While wiring the reproducible Node lane, it exposed placeholder-count mismatches in `src/core/services/immersion-tracker/storage.ts`; fixing those placeholders makes the SQLite-backed persistence/finalization tests pass cross-runtime, covering session finalization, telemetry persistence, and storage-session write paths.

+
+Restored a guard in `src/core/services/cli-command.ts` that ignores second-instance `--start` when the overlay runtime is already initialized, but still allows other flags in the same invocation to run.
+
+Verification: `bun test src/core/services/cli-command.test.ts`, `bun run test:core:src`, and `bun run test` all pass; the six immersion tracker tests remain skipped as before.
+
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+
+Restored the missing second-instance `--start` guard in `src/core/services/cli-command.ts`.
+
+- Added an `ignoreSecondInstanceStart` check so `handleCliCommand` logs `Ignoring --start because SubMiner is already running.` when a second-instance `--start` arrives after the overlay runtime is already initialized.
+- Updated start gating so pure duplicate `--start` requests no longer reconnect the MPV client, while combined commands such as `--start --toggle-visible-overlay` still execute their non-start behavior and can connect through those paths.
+- Verified the regression with existing CLI command coverage and reran the broader test targets.
+
+Tests run:
+
+- `bun test src/core/services/cli-command.test.ts`
+- `bun run test:core:src`
+- `bun run test`
+
+Notes:
+
+- The six skipped immersion tracker tests are unchanged from the pre-fix baseline.
