 # Changelog
 
+## v0.12.0 (2026-04-11)
+
+### Changed
+- Overlay: Added configurable overlay shortcuts for session help, controller select, and controller debug actions.
+- Overlay: Added mpv/plugin and CLI routing for session help, controller utilities, and subtitle sidebar toggling through the shared session-action path.
+- Overlay: Improved dedicated overlay modal retry and focus handling for runtime options, Jimaku, session help, controller tools, and the playlist browser.
+- Overlay: Fixed controller configuration and controller debug shortcut opens so configured bindings bring up their modals again instead of tripping renderer recovery.
+- Stats: Sessions are rolled up per episode within each day, with a bulk delete that wipes every session in the group.
+- Stats: Trends add a 365-day range next to the existing 7d/30d/90d/all options.
+- Stats: Library detail view gets a delete-episode action that removes the video and all its sessions.
+- Stats: Vocabulary Top 50 tightens the word/reading column so katakana entries no longer push the scores off screen.
+- Stats: Episode detail hides card events whose Anki notes have been deleted, instead of showing phantom mining activity.
+- Stats: Trend and watch-time charts share a unified theme with horizontal gridlines and larger ticks for legibility.
+- Stats: Overview, Library, Trends, Sessions, and Vocabulary now use generic "title" wording so YouTube videos and anime live comfortably side by side in the dashboard.
+- Stats: Session timeline no longer plots seek-forward/seek-backward markers — they were too noisy on sessions with lots of rewinds.
+- Stats: Replaced the "Library — Per Day" section on the Stats → Trends page with a "Library — Summary" section. The new section shows a top-10 watch-time leaderboard chart and a sortable per-title table (watch time, videos, sessions, cards, words, lookups, lookups/100w, date range), all scoped to the current date range selector.
+
+### Fixed
+- Overlay: Fixed overlay drag-and-drop routing so dropping external subtitle files like `.ass` onto mpv still loads them when the overlay is visible.
+- Overlay: Addressed the latest CodeRabbit follow-ups on PR #49, including generation-scoped Lua session binding names, stricter session command validation, session-help shortcut visibility, the numeric-selection key guard, stats-overlay startup classification, and safer session-binding persistence.
+- Overlay: Addressed the latest CodeRabbit follow-ups on the Windows overlay flow, including exact mpv target resolution, lower-overlay helper arguments, Win32 failure detection, and overlay cleanup on tracker loss.
+- Overlay: Fixed Windows overlay z-order so the visible subtitle overlay stops staying above unrelated apps after mpv loses focus.
+- Overlay: Fixed Windows overlay tracking to use native window polling and owner/z-order binding, which keeps the subtitle overlay aligned to the active mpv window more reliably.
+- Overlay: Fixed Windows overlay hide/restore behavior so minimizing mpv immediately hides the overlay and restoring mpv brings it back on top of the mpv window without requiring a click.
+- Overlay: Fixed stats overlay layering so the in-player stats page now stays above mpv and the subtitle overlay while it is open.
+- Overlay: Fixed Windows subtitle overlay stability so transient tracker misses and restore events keep the current subtitle visible instead of waiting for the next subtitle line.
+- Overlay: Fixed Windows focus handoff from the interactive subtitle overlay back to mpv so the overlay no longer drops behind mpv and briefly disappears.
+- Overlay: Fixed Windows visible-overlay startup so it no longer briefly opens as an interactive or opaque surface before the tracked transparent overlay state settles.
+- Overlay: Fixed spurious auto-pause after overlay visibility recovery and window resize so the overlay no longer pauses mpv until the pointer genuinely re-enters the subtitle area.
+- Overlay: Fixed Windows secondary subtitle hover mode so the expanded hover hit area no longer blocks the native minimize, maximize, and close buttons.
+- Overlay: Fixed Windows Yomitan popup focus loss after closing nested lookups so the original popup stays interactive instead of falling through to mpv.
+- Stats: Fixed immersion-tracker timestamp handling under Bun/libsql so library rows, session timelines, and lifetime summaries keep real wall-clock millisecond values instead of truncating to invalid negative timestamps.
+- Mpv Plugin: Fixed the mpv Lua plugin so hover and environment modules no longer use the `goto continue` pattern that can fail to parse on some user Lua runtimes.
+
+### Internal
+- Release: Added a dedicated beta/rc prerelease GitHub Actions workflow that publishes GitHub prereleases without consuming pending changelog fragments or updating AUR.
+- Release: Added prerelease note generation so beta and release-candidate tags can reuse the current pending `changes/*.md` fragments while leaving stable changelog publication for the final release cut.

+- Launcher: Replaced the launcher-only fullscreen toggle with `mpv.launchMode` so SubMiner-managed mpv playback can start in normal, maximized, or fullscreen mode.
+
+### Fixed
+- Launcher: Fixed launcher-managed mpv spawning to force an explicit X11 GPU path when Wayland trackers are unavailable.
+- Launcher: Local playback now promotes a single unlabeled external subtitle sidecar to the primary slot instead of leaving mpv's embedded English auto-selection in place.
+- Release: Fixed Linux AppImage startup packaging so Chromium child relaunches can resolve the bundled `libffmpeg.so` instead of crash-looping on startup.

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+User report: toggling the visible overlay with mpv `y-t` is inconsistent. After manually toggling through the `y-y` menu, `y-t` may allow one hide, but after toggling back on it can stop hiding the overlay again, forcing the user back into the menu path.
+
+Initial assessment:
+
+- no active backlog item currently tracks this exact report
+- nearest prior work is `TASK-248`, which fixed a macOS-specific visible-overlay restore bug and is marked done
+- current targeted regressions for the old fix surface pass, including plugin ready-signal suppression, focused-overlay `y-t` proxy dispatch, autoplay-ready gate deduplication, and blur-path restacking guards
+
+This should be treated as a fresh investigation unless reproduction proves it is the same closed macOS issue resurfacing on the current build.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [ ] #1 Reproduce the reported `y-t` / `y-y` inconsistency on the affected platform and identify the exact event sequence
+- [ ] #2 Determine whether the failure is in mpv plugin command dispatch, focused-overlay key forwarding, or main-process visible-overlay state transitions
+- [ ] #3 Fix the inconsistency so repeated hide/show/hide cycles work from `y-t` without requiring menu recovery
+- [ ] #4 Add regression coverage for the reproduced failing sequence
+- [ ] #5 Record whether this is a regression of `TASK-248` or a distinct bug
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Reproduce the report with platform/build details and capture whether the failing `y-t` press originates in raw mpv or the focused overlay y-chord proxy path.
+2. Trace visible-overlay state mutations across plugin toggle commands, autoplay-ready callbacks, and main-process visibility/window blur handling.
+3. Patch the narrowest failing path and add regression coverage for the exact hide/show/hide sequence.
+4. Re-run targeted plugin, overlay visibility, overlay window, and renderer keyboard suites before broader verification.

+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Assessed PR #49 CodeRabbit threads. Fixed the real regressions in first-run CLI gating, IPC session-action validation, renderer controller-modal lifecycle notifications, async subtitle-sidebar toggle guarding, plugin config-dir resolution priority, prerelease artifact upload failure handling, immersion tracker lazy startup, win32 z-order error handling, and Windows socket-aware mpv matching.
+
+Review assessment: the overlay-shortcut lifecycle comment is obsolete for the current architecture because overlay-local shortcuts are intentionally handled through the local fallback path and the runtime only tracks configured-state/cleanup. Refactor-only nit comments for splitting `scripts/build-changelog.ts` and `src/core/services/session-bindings.ts` were left as follow-up quality work, not behavior bugs in this PR round.
+
+Verification: `bun test src/main/runtime/first-run-setup-service.test.ts src/core/services/session-bindings.test.ts src/core/services/app-ready.test.ts src/core/services/ipc.test.ts src/renderer/handlers/keyboard.test.ts src/main/overlay-runtime.test.ts src/window-trackers/mpv-socket-match.test.ts`, `bun test src/window-trackers/windows-tracker.test.ts`, `bun run typecheck`, `lua scripts/test-plugin-lua-compat.lua`.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Assessed the current CodeRabbit round on PR #49 and addressed the still-valid behavior issues rather than blanket-applying every bot suggestion. The branch now treats the new session/stats CLI flags as explicit startup commands during first-run setup, validates the new session actions through IPC, points session-binding command diagnostics at the correct config field, keeps immersion tracker startup lazy until later runtime triggers, and notifies overlay modal lifecycle state when controller-select/debug are opened from local keyboard bindings. I also switched the subtitle-sidebar IPC callback to the async guarded path so promise rejections feed renderer recovery instead of being dropped.
+
+On the Windows/plugin side, the mpv plugin now prefers config-file matches before falling back to an existing config directory, prerelease workflow uploads fail if expected Linux/macOS artifacts are missing, the Win32 z-order bind path now validates the `GetWindowLongW` call for the window above mpv, and the Windows tracker now passes the target socket path into native polling and filters mpv instances by command line so multiple sockets can be distinguished on Windows. Added/updated regression coverage for first-run gating, IPC validation, session-binding diagnostics, controller modal lifecycle notifications, modal ready-listener dispatch, and socket-path matching. Verification run: `bun run typecheck`, the targeted Bun test suites for the touched areas, `bun test src/window-trackers/windows-tracker.test.ts`, and `lua scripts/test-plugin-lua-compat.lua`.

+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Assessed five unresolved PR #49 threads after 9ce5de2f. Fixed prerelease workflow cache keys to include `runner.arch`, changed prerelease publishing to validate artifacts before release creation/edit and only undraft after uploads complete, tightened Windows socket matching to require exact argument boundaries, and stopped memoizing null command-line lookup misses in the Win32 cache path.
+
+Stale assessment: the `src/core/services/overlay-shortcut.ts` thread is still obsolete. Current code at `registerOverlayShortcuts()` returns `hasConfiguredOverlayShortcuts(shortcuts)`, not `false`, and the overlay-local handling remains intentionally driven by local fallback dispatch rather than global registration in this runtime path.

+Verification: `bun test src/prerelease-workflow.test.ts src/window-trackers/mpv-socket-match.test.ts`, `bun test src/window-trackers/windows-tracker.test.ts src/prerelease-workflow.test.ts src/window-trackers/mpv-socket-match.test.ts`, `bun run typecheck`.

+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Handled the next CodeRabbit round on PR #49 by fixing the still-valid prerelease workflow and Windows socket-matching issues while documenting the stale overlay-shortcut comment instead of forcing a no-op code change. The prerelease workflow now scopes all dependency caches by `runner.arch`, validates the final artifact set before touching the GitHub release, creates/edits the prerelease as a draft during uploads, and only flips `--draft=false` after all assets succeed. On Windows, socket matching now requires an exact `--input-ipc-server` argument boundary so `subminer-1` no longer matches `subminer-10`, and transient PowerShell/CIM misses no longer get cached forever as null command lines.
+
+Regression coverage was added for the workflow invariants and exact socket matching. Verification passed with targeted prerelease workflow tests, Windows tracker tests, socket-matcher tests, and `bun run typecheck`.

+
+Fix shipped by parsing timestamp strings without the broken `Number(largeString)` path, migrating `imm_session_events.ts_ms` to `TEXT`, ordering/retention queries via `CAST(ts_ms AS REAL)`, and avoiding `Number(currentMs)` when reusing already-normalized timestamp strings.

+Reapplied the stable changelog build entrypoint fix on main: added `writeStableReleaseArtifacts`, covered it with a focused regression test, and updated `package.json` so `changelog:build` forwards `--version` and `--date` through a single `build-release` command.
+
+Verified the formatted mainline release tree with `bun run changelog:lint`, `bun run changelog:check --version 0.12.0`, `bun run verify:config-example`, `bun run typecheck`, `bun run test:fast`, `bun run test:env`, `bun run build`, `bun run docs:test`, `bun run docs:build`, and `bun run test:smoke:dist`; all passed.
+
+Remote main CI also completed successfully for `Windows update (#49)` after the local release-prep pass. Remaining operational steps are commit/tag/push only.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Prepared `main` for the stable `v0.12.0` cut. Formatted the previously failing source files so `bun run format:check:src` is now clean, bumped `package.json` from `0.12.0-beta.3` to `0.12.0`, and generated the stable release artifacts with the explicit local cut date `2026-04-11`, which consumed the pending changelog fragments into `CHANGELOG.md`, `docs-site/changelog.md`, and `release/release-notes.md`.
+
+Also reintroduced the release-script fix on main: the old `changelog:build` package script still used `build && docs`, which can drop `--version/--date` on the first step. Added a focused regression test in `scripts/build-changelog.test.ts`, implemented `writeStableReleaseArtifacts` in `scripts/build-changelog.ts`, and switched `package.json` to `build-release` so release flags propagate correctly. Verification on the final tree passed for formatting, changelog lint/check, config example verification, typecheck, fast tests, env tests, build, docs tests/build, dist smoke, and remote main CI. The branch is release-ready pending commit, tag, and push.

 # Changelog
 
-## v0.11.1 (2026-04-04)
+## v0.12.0 (2026-04-11)
 
-- Fixed Linux packaged builds to expose the canonical `SubMiner` app identity to Electron's startup metadata so native Wayland compositors stop reporting the window class/app-id as lowercase `subminer`.
-- Fixed Linux to restore the runtime options, Jimaku, and Subsync shortcuts after the Electron 39 regression by routing those actions through the overlay's mpv/IPC shortcut path.
+**Changed**
+- Overlay: Added configurable overlay shortcuts for session help, controller select, and controller debug actions.
+- Overlay: Added mpv/plugin and CLI routing for session help, controller utilities, and subtitle sidebar toggling through the shared session-action path.
+- Overlay: Improved dedicated overlay modal retry and focus handling for runtime options, Jimaku, session help, controller tools, and the playlist browser.
+- Overlay: Fixed controller configuration and controller debug shortcut opens so configured bindings bring up their modals again instead of tripping renderer recovery.
+- Stats: Sessions are rolled up per episode within each day, with a bulk delete that wipes every session in the group.
+- Stats: Trends add a 365-day range next to the existing 7d/30d/90d/all options.
+- Stats: Library detail view gets a delete-episode action that removes the video and all its sessions.
+- Stats: Vocabulary Top 50 tightens the word/reading column so katakana entries no longer push the scores off screen.
+- Stats: Episode detail hides card events whose Anki notes have been deleted, instead of showing phantom mining activity.
+- Stats: Trend and watch-time charts share a unified theme with horizontal gridlines and larger ticks for legibility.
+- Stats: Overview, Library, Trends, Sessions, and Vocabulary now use generic "title" wording so YouTube videos and anime live comfortably side by side in the dashboard.
+- Stats: Session timeline no longer plots seek-forward/seek-backward markers — they were too noisy on sessions with lots of rewinds.
+- Stats: Replaced the "Library — Per Day" section on the Stats → Trends page with a "Library — Summary" section. The new section shows a top-10 watch-time leaderboard chart and a sortable per-title table (watch time, videos, sessions, cards, words, lookups, lookups/100w, date range), all scoped to the current date range selector.
 
-## v0.11.0 (2026-04-03)
+**Fixed**
+- Overlay: Fixed overlay drag-and-drop routing so dropping external subtitle files like `.ass` onto mpv still loads them when the overlay is visible.
+- Overlay: Addressed the latest CodeRabbit follow-ups on PR #49, including generation-scoped Lua session binding names, stricter session command validation, session-help shortcut visibility, the numeric-selection key guard, stats-overlay startup classification, and safer session-binding persistence.
+- Overlay: Addressed the latest CodeRabbit follow-ups on the Windows overlay flow, including exact mpv target resolution, lower-overlay helper arguments, Win32 failure detection, and overlay cleanup on tracker loss.
+- Overlay: Fixed Windows overlay z-order so the visible subtitle overlay stops staying above unrelated apps after mpv loses focus.
+- Overlay: Fixed Windows overlay tracking to use native window polling and owner/z-order binding, which keeps the subtitle overlay aligned to the active mpv window more reliably.
+- Overlay: Fixed Windows overlay hide/restore behavior so minimizing mpv immediately hides the overlay and restoring mpv brings it back on top of the mpv window without requiring a click.
+- Overlay: Fixed stats overlay layering so the in-player stats page now stays above mpv and the subtitle overlay while it is open.
+- Overlay: Fixed Windows subtitle overlay stability so transient tracker misses and restore events keep the current subtitle visible instead of waiting for the next subtitle line.
+- Overlay: Fixed Windows focus handoff from the interactive subtitle overlay back to mpv so the overlay no longer drops behind mpv and briefly disappears.
+- Overlay: Fixed Windows visible-overlay startup so it no longer briefly opens as an interactive or opaque surface before the tracked transparent overlay state settles.
+- Overlay: Fixed spurious auto-pause after overlay visibility recovery and window resize so the overlay no longer pauses mpv until the pointer genuinely re-enters the subtitle area.
+- Overlay: Fixed Windows secondary subtitle hover mode so the expanded hover hit area no longer blocks the native minimize, maximize, and close buttons.
+- Overlay: Fixed Windows Yomitan popup focus loss after closing nested lookups so the original popup stays interactive instead of falling through to mpv.
+- Stats: Fixed immersion-tracker timestamp handling under Bun/libsql so library rows, session timelines, and lifetime summaries keep real wall-clock millisecond values instead of truncating to invalid negative timestamps.
+- Mpv Plugin: Fixed the mpv Lua plugin so hover and environment modules no longer use the `goto continue` pattern that can fail to parse on some user Lua runtimes.
 
-- Added a playlist browser overlay modal for browsing sibling video files and the live mpv queue during playback, with a default `Ctrl+Alt+P` keybinding.
-- Made mpv plugin installation mandatory in first-run setup (removed skip path); Finish stays disabled until the plugin is installed.
-- Fixed the Windows `SubMiner mpv` shortcut to launch mpv with required default args directly instead of requiring an `mpv.conf` profile named `subminer`.
-- Fixed the Windows mpv idle launch so loading a video after opening the shortcut keeps mpv in the SubMiner-managed session and auto-starts the overlay.
-- Added a blank-by-default `mpv.executablePath` config override for Windows playback when mpv is not on `PATH`, exposed in first-run setup.
-- Fixed Kiku duplicate grouping to reuse duplicate note IDs from both sentence-card creation and Yomitan popup mining, with background card addition and proper merge-modal sequencing.
-- Fixed configured subtitle-jump keybindings to keep playback paused when invoked from a paused state.
-- Fixed managed local subtitle auto-selection to reuse configured language priorities instead of staying on mpv's initial `sid=auto` guess.
-- Kept tracked macOS visible overlays click-through by default so subtitle sidebar passthrough works immediately.
-- Stopped AniList post-watch from sending duplicate progress updates when already satisfied by a retry item.
-- Kept integrated `--start --texthooker` launches on the full app-ready startup path.
-- Honored `SUBMINER_YTDLP_BIN` consistently across all YouTube flows (playback URL resolution, track probing, subtitle downloads, metadata probing).
-- Added `windows` as a recognized launcher backend option and auto-detection target.
-- Added a dedicated Subtitle Sidebar guide to the docs site with links from homepage and configuration docs.
+**Internal**
+- Release: Added a dedicated beta/rc prerelease GitHub Actions workflow that publishes GitHub prereleases without consuming pending changelog fragments or updating AUR.
+- Release: Added prerelease note generation so beta and release-candidate tags can reuse the current pending `changes/*.md` fragments while leaving stable changelog publication for the final release cut.
 
-## v0.10.0 (2026-03-29)
+## Previous Versions
 
-- Fixed stats startup so the immersion tracker can run when `Bun.serve` is unavailable.
-- Added a Node `http` fallback for Electron/runtime paths that do not expose Bun, so stats keeps working there too.
-- Updated Discord Rich Presence to the maintained `@xhayper/discord-rpc` wrapper.
-- Fixed the macOS visible-overlay toggle path so manual hides stay hidden and the plugin uses the explicit visible-overlay toggle command.
-- Restored macOS mpv passthrough while the overlay subtitle sidebar is open so clicks outside the sidebar can refocus mpv and keep native keybindings working.

+<summary>v0.11.x</summary>
 
-## v0.9.3 (2026-03-25)
+<h2>v0.11.2 (2026-04-07)</h2>
 
-- Moved YouTube primary subtitle language defaults to `youtube.primarySubLanguages`.
-- Removed the placeholder YouTube subtitle retime step; downloaded primary subtitle tracks are now used directly.
-- Removed the old internal YouTube retime helper and its tests.
-- Clarified optional `alass` / `ffsubsync` subtitle-sync setup and fallback behavior in the docs.
-- Removed the legacy `youtubeSubgen.primarySubLanguages` config path from generated config and docs.
+**Changed**
+- Launcher: Replaced the launcher-only fullscreen toggle with `mpv.launchMode` so SubMiner-managed mpv playback can start in normal, maximized, or fullscreen mode.
 
-## v0.9.2 (2026-03-25)
+**Fixed**
+- Launcher: Fixed launcher-managed mpv spawning to force an explicit X11 GPU path when Wayland trackers are unavailable.
+- Launcher: Local playback now promotes a single unlabeled external subtitle sidecar to the primary slot instead of leaving mpv's embedded English auto-selection in place.
+- Release: Fixed Linux AppImage startup packaging so Chromium child relaunches can resolve the bundled `libffmpeg.so` instead of crash-looping on startup.
 
-- Fixed overlay pointer tracking so Windows click-through toggles immediately when the cursor enters or leaves subtitle regions.
-- Fixed Windows overlay window tracking on scaled displays by converting native tracked window bounds to Electron DIP coordinates.
-- Fixed Windows direct `--youtube-play` startup so MPV boots reliably, stays paused until the app-owned subtitle flow is ready, and reuses an already-running SubMiner instance.
-- Fixed standalone Windows `--youtube-play` sessions so closing MPV fully exits SubMiner instead of leaving hidden overlay windows behind.
-- Fixed `subminer <youtube-url>` on Linux so the YouTube playback flow waits for Yomitan to load before creating the overlay window.
+<h2>v0.11.1 (2026-04-04)</h2>
 
-## v0.9.1 (2026-03-24)
+**Fixed**
+- Release: Linux packaged builds now expose the canonical `SubMiner` app identity to Electron's startup metadata so native Wayland compositors stop reporting the window class/app-id as lowercase `subminer`.
+- Linux: Linux now restores the runtime options, Jimaku, and Subsync shortcuts after the Electron 39 regression by routing those actions through the overlay's mpv/IPC shortcut path.
 
-- Reduced packaged release size by excluding duplicate `extraResources` payload and pruning docs, tests, sourcemaps, and other source-only files from Electron bundles.
-- Restored controller navigation and lookup/mining controls while the subtitle sidebar is open, while keeping true modal dialogs blocking controller actions.
-- Fixed subtitle annotation clearing so explanatory contrast endings like `んですけど` are excluded consistently across the shared tokenizer filter and annotation stage.
+<h2>v0.11.0 (2026-04-03)</h2>
 
-## v0.9.0 (2026-03-23)
+**Added**
+- Overlay: Added a playlist browser overlay modal for browsing sibling video files and the live mpv queue during playback.
+- Overlay: Added the default `Ctrl+Alt+P` keybinding to open the playlist browser and manage queue order without leaving playback.
 
-- Added an app-owned YouTube subtitle flow with absPlayer-style timedtext parsing that auto-loads the default primary subtitle plus a best-effort secondary at startup and resumes once the primary is ready.
-- Added a manual YouTube subtitle picker on `Ctrl+Alt+C` so subtitle selection can be retried on demand during active YouTube playback.
-- Added yt-dlp metadata probing so YouTube playback and immersion tracking record canonical video title and channel metadata.
-- Disabled conflicting mpv native subtitle auto-selection for the app-owned flow so injected explicit tracks stay authoritative.
-- Added OSD status updates covering YouTube playback startup, subtitle acquisition, and subtitle loading.
-- Stopped forcing `--ytdl-raw-options=` before user-provided mpv options so existing YouTube cookie integrations are preserved.
-- Improved sidebar startup/resume behavior, scroll handling, and overlay/sidebar subtitle synchronization.
-- Stats Library tab now shows YouTube video title, channel name, and thumbnail for YouTube media entries.
-- Added a new WebSocket / Texthooker API integration guide covering payload formats, custom client patterns, and mpv plugin automation.
-- Fixed Anki media mining for mpv YouTube streams so audio and screenshot capture work correctly during YouTube playback sessions.
-- Fixed YouTube media path handling in immersion tracking so YouTube sessions record correct media references and AniList state transitions do not fire for YouTube media.
-- Reused existing authoritative YouTube subtitle tracks when present, fell back only for missing sides, and kept native mpv secondary subtitle rendering hidden so the overlay remains the visible secondary subtitle surface.
+**Changed**
+- Setup: Made mpv plugin installation mandatory in the first-run setup flow, removed the skip path, and kept Finish disabled until the plugin is installed.
+- Setup: Clarified that the mpv plugin requirement applies to setup on every platform, while the optional `SubMiner mpv` shortcut remains the recommended Windows playback entry point.
+- Launcher: Streamlined Windows setup and config by making the `SubMiner mpv` shortcut self-contained and keeping `mpv.executablePath` as the simple fallback when `mpv.exe` is not on `PATH`.
+- Overlay: Changed fresh-install default config to keep texthooker and stats from auto-opening browser tabs.
+- Overlay: Changed fresh-install default config to enable AnkiConnect, Discord Rich Presence, subtitle-sidebar, and Yomitan-popup auto-pause by default, while disabling controller input by default.
 
-## v0.8.0 (2026-03-22)
+**Fixed**
+- Main: Resolve the YouTube playback socket path lazily so startup honors CLI and config overrides.
+- Main: Add regression coverage for the lazy socket-path lookup during Windows mpv startup.
+- Main: Keep integrated `--start --texthooker` launches on the full app-ready startup path so the texthooker page and websocket servers start together during normal playback startup.
+- Main: Stop the mpv/plugin auto-start flow from spawning a separate standalone texthooker helper during normal `subminer <video>` launches.
+- Overlay: Keep tracked macOS visible overlays click-through by default so subtitle sidebar passthrough works immediately without requiring a subtitle hover cycle first.
+- Overlay: Add regression coverage for the macOS visible-overlay passthrough default.
+- Anilist: Stop AniList post-watch from sending a second progress update when the current episode was already satisfied by a ready retry item in the same watch-completion pass.
+- Anilist: Add regression coverage for the retry-queue plus live-update duplicate path.
+- Overlay: Fixed Kiku duplicate grouping to reuse duplicate note IDs from both generic sentence-card creation and Yomitan popup mining instead of running extra duplicate scans after add.
+- Overlay: Fixed the Yomitan popup mining flow to add cards in the background while keeping the stock popup progress feedback, then pause playback and close the lookup popup before the Kiku merge modal opens.
+- Overlay: Fixed configured subtitle-jump keybindings so backward and forward subtitle seeks keep playback paused when invoked from a paused state.
+- Launcher: Fixed the Windows `SubMiner mpv` shortcut and `SubMiner.exe --launch-mpv` flow to launch mpv with SubMiner's required default args directly instead of requiring an `mpv.conf` profile named `subminer`.
+- Launcher: Clarified the Windows install and usage docs so the shortcut path is documented as self-contained, while the optional `subminer` mpv profile remains available for manual mpv launches.
+- Launcher: Hardened the first-run setup blocker copy and stale custom-scheme handling so setup messages stay aligned with config, plugin, and dictionary readiness.
+- Launcher: Fixed the Windows `SubMiner mpv` shortcut idle launch so loading a video after opening the shortcut keeps mpv in the expected SubMiner-managed session, auto-starts the overlay, and re-arms subtitle auto-selection for the newly opened file.
+- Launcher: Removed the redundant `.` subtitle search path from the Windows shortcut launch args and deduped repeated subtitle source tracks in the manual sync picker so duplicate external subtitle entries no longer appear from the shortcut path.
+- Playback: Fixed managed local playback so duplicate startup-ready retries no longer unpause media after a later manual pause on the same file.
+- Playback: Fixed managed local subtitle auto-selection so local files reuse configured primary and secondary subtitle language priorities instead of staying on mpv's initial `sid=auto` guess.
+- Launcher: Added a blank-by-default `mpv.executablePath` override for Windows playback so users can point SubMiner at `mpv.exe` when it is not on `PATH`.
+- Launcher: Kept the Windows shortcut and `--launch-mpv` flow simple by preserving PATH auto-discovery as the default and exposing the override in first-run setup.
+- Launcher: Added `windows` as a recognized launcher backend option and auto-detection target on Windows.
+- Launcher: Honored `SUBMINER_YTDLP_BIN` consistently across YouTube playback URL resolution, track probing, subtitle downloads, and metadata probing.
+- Launcher: Kept the first-run setup window from navigating away on unexpected URLs.
+- Launcher: Made Windows mpv honor an explicitly configured executable path instead of silently falling back to PATH.
+- Launcher: Hardened `--launch-mpv` parsing and Windows binary resolution so valueless flags do not swallow media targets and symlinked launcher installs do not short-circuit PATH lookup.
+- Launcher: Fixed first-run setup blocking playback on macOS when the SubMiner mpv plugin was already installed at the canonical `~/.config/mpv` path.
+- Launcher: Fixed setup gating so stale cancelled setup state no longer prevents playback when the canonical mpv plugin entrypoint already exists.
+- Playback: Prevented stale async playlist-browser subtitle rearm callbacks from overriding newer subtitle selections during rapid file changes.
 
-- Added a configurable subtitle sidebar feature (`subtitleSidebar`) with overlay/embedded rendering, click-to-seek cue list, and hot-reloadable visibility and behavior controls.
-- Added a rendered sidebar modal with cue list display, click-to-seek, active-cue highlighting, and embedded layout support.
-- Added sidebar snapshot plumbing between main and renderer for overlay/sidebar synchronization.
-- Added sidebar configuration options for visibility and behavior (enabled, layout, toggle key, autoOpen, pauseOnHover, autoScroll) plus typography and sizing controls.
-- Documented `subtitleSidebar` configuration and behavior in user-facing docs (configuration.md, shortcuts.md, config.example.jsonc).
-- Updated subtitle prefetch/rendering flow to keep overlay and sidebar state in sync through media transitions.
-- Kept sidebar cue tracking stable across playback transitions and timing edge cases.
-- Fixed sidebar startup/resume positioning to jump directly to the first resolved active cue.
-- Prevented stale subtitle refreshes from regressing active-cue state.
+**Docs**
+- Docs Site: Added a dedicated Subtitle Sidebar guide and linked it from the homepage and configuration docs.
+- Docs Site: Linked Jimaku integration from the homepage to its dedicated docs page.
+- Docs Site: Refreshed docs-site theme tokens and hover/selection styling for the updated pages.
 
-## v0.7.0 (2026-03-19)
+**Internal**
+- Release: Retried AUR clone and push operations in the tagged release workflow.
+- Release: Kept GitHub Releases green when AUR publish flakes and needs manual follow-up.
+- Release: Updated Electron to 39.8.6 and pinned patched transitive build dependencies to clear the reported high-severity audit findings.
 
-- Added a full local immersion dashboard release line with Overview, Library, Trends, Vocabulary, and Sessions drill-down views backed by SQLite tracking data.
-- Added browser-first stats workflows: `subminer stats`, background stats daemon controls (`-b` / `-s`), stats cleanup, and dashboard-side mining actions with media enrichment.
-- Improved stats accuracy and scale handling with Yomitan token counts, full session timelines, known-word timeline fixes, cross-media vocabulary fixes, and clearer session charts.
-- Improved overlay/runtime stability with quieter macOS fullscreen recovery, reduced repeated loading OSD popups, and better frequency/noise handling for subtitle annotations.
-- Added launcher mpv-args passthrough plus Linux plugin wrapper-name fallback for packaged installs.
-- Added a hover-revealed ↗ button on Sessions tab rows to navigate directly to the anime media-detail view, with correct "Back to Sessions" back-navigation.
-- Excluded auxiliary-stem `そうだ` grammar tails (MeCab POS3 `助動詞語幹`) from subtitle annotation metadata so frequency, JLPT, and N+1 styling no longer bleed onto grammar-tail tokens.
+</details>
 
-## v0.6.5 (2026-03-15)
+<details>
+<summary>v0.10.x</summary>
 
-- Seeded the AUR checkout with the repo `.SRCINFO` template before rewriting metadata so tagged releases do not depend on prior AUR state.
+<h2>v0.10.0 (2026-03-29)</h2>
 
-## v0.6.4 (2026-03-15)
+**Changed**
+- Integrations: Replaced the deprecated Discord Rich Presence wrapper with the maintained `@xhayper/discord-rpc` package.
 
-- Reworked AUR metadata generation to update `.SRCINFO` directly instead of depending on runner `makepkg`, fixing tagged release publishing for `subminer-bin`.
+**Fixed**
+- Stats: Fixed stats startup so the immersion tracker can run when `Bun.serve` is unavailable.
+- Stats: Stats server now falls back to a Node `http` listener in Electron/runtime paths that do not expose Bun.
+- Overlay: Fixed the macOS visible-overlay toggle path so manual hides stay hidden and the plugin uses the explicit visible-overlay toggle command.
+- Subtitle Sidebar: Restored macOS mpv passthrough while the overlay subtitle sidebar is open so clicks outside the sidebar can refocus mpv and keep native keybindings working.
 
-## v0.6.3 (2026-03-15)
+**Internal**
+- Release: Added a maintained source coverage lane that shards Bun coverage one test file at a time and merges LCOV output into `coverage/test-src/lcov.info`.
+- Release: CI and release quality-gate now upload the merged source-lane LCOV artifact for inspection.
+- Runtime: Extracted remaining inline runtime logic from `src/main.ts` into dedicated runtime modules and composer helpers.
+- Runtime: Added focused regression tests for the extracted runtime/composer boundaries.
+- Runtime: Updated task tracking notes to mark TASK-238.6 complete and confirm follow-on boot-phase split can be deferred.
+- Runtime: Split `src/main.ts` boot wiring into dedicated `src/main/boot/services.ts`, `src/main/boot/runtimes.ts`, and `src/main/boot/handlers.ts` modules.
+- Runtime: Added focused tests for the new boot-phase seams and kept the startup/typecheck/build verification lanes green.
+- Runtime: Updated internal architecture/task docs to record the boot-phase split and new ownership boundary.
 
-- Expanded `Alt+C` into an inline controller config/remap flow with preferred-controller saving and per-action learn mode for buttons, triggers, and stick directions.
-- Automated `subminer-bin` AUR package updates from the tagged release workflow.
+</details>
 
-## v0.6.2 (2026-03-12)
+<details>
+<summary>v0.9.x</summary>
 
-- Added `yomitan.externalProfilePath` so SubMiner can reuse another Electron app's Yomitan profile in read-only mode.
-- Reused external Yomitan dictionaries/settings without writing back to that profile.
-- Let launcher-managed playback honor external Yomitan config instead of forcing first-run setup.

+<h2>v0.9.3 (2026-03-25)</h2>
 
-## v0.6.1 (2026-03-12)
+**Changed**
+- Launcher: Moved YouTube primary subtitle language defaults to `youtube.primarySubLanguages`.
+- Launcher: Removed the placeholder YouTube subtitle retime step and now uses downloaded primary subtitle tracks directly, so there is no fake path rewrite before playback/sidebar loading.
+- YouTube: Removed the `src/core/services/youtube/retime` helper and its tests after retiring the internal retime strategy.
+- Docs: Clarified optional `alass` / `ffsubsync` subtitle-sync requirements and setup steps, including fallback behavior when sync tools are absent.
+- Launcher: Removed the old `youtubeSubgen.primarySubLanguages` config path from the generated config and docs.
 
-- Added Chrome Gamepad API controller support for keyboard-only overlay mode.
-- Added configurable controller bindings for lookup, mining, popup navigation, Yomitan audio, mpv pause, and d-pad fallback navigation.
-- Added smooth, slower popup scrolling for controller navigation.
-- Expanded `Alt+C` into a controller config/remap modal with preferred-controller saving, inline learn mode, and kept `Alt+Shift+C` for raw input debugging.
-- Added a transient in-overlay controller-detected indicator when a controller is first found.
-- Fixed cleanup of stale keyboard-only token highlights when keyboard-only mode is disabled or when the Yomitan popup closes.
-- Added an enforced `verify:config-example` gate so checked-in example config artifacts cannot drift silently.
+<h2>v0.9.2 (2026-03-25)</h2>
 
-## v0.5.6 (2026-03-10)
+**Fixed**
+- Overlay: Fixed overlay pointer tracking so Windows click-through toggles immediately when the cursor enters or leaves subtitle regions, without waiting for a later hover resync.
+- Overlay: Fixed Windows overlay window tracking on scaled displays by converting native tracked window bounds to Electron DIP coordinates before applying overlay bounds.
+- Launcher: Fixed Windows direct `--youtube-play` startup so MPV boots reliably, stays paused until the app-owned subtitle flow is ready, and reuses an already-running SubMiner instance when available.
+- Launcher: Fixed standalone Windows `--youtube-play` sessions so closing MPV fully exits SubMiner instead of leaving hidden overlay windows or a background process behind.
+- Overlay: Fixed `subminer <youtube-url>` on Linux so the YouTube playback flow waits for Yomitan to load before creating the overlay window, avoiding the broken lookup popup state that previously required a manual overlay refresh.
 
-- Persisted 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.
-- Fixed early Electron startup writing config and user data under a lowercase `~/.config/subminer` path instead of canonical `~/.config/SubMiner`.
-- Kept JLPT underline colors stable during Yomitan hover and selection states, even when tokens also use known, N+1, name-match, or frequency styling.
+<h2>v0.9.1 (2026-03-24)</h2>
 
-## v0.5.1 (2026-03-09)
+**Changed**
+- Release: Reduced packaged release size by excluding duplicate `extraResources` payload and pruning docs, tests, sourcemaps, and other source-only files from Electron bundles.
 
-- Removed the old YouTube subtitle-generation mode switch; YouTube playback now resolves subtitles before mpv starts.
-- Hardened YouTube AI subtitle fixing so fenced/text-only responses keep original cue timing.
-- Skipped AniSkip during URL/YouTube playback where anime metadata cannot be resolved reliably.
-- Kept the background SubMiner process warm across launcher-managed mpv exits so reconnects do not repeat startup pause/warmup work.
-- Fixed Windows single-instance reuse so overlay and video launches reuse the running background app instead of booting a second full app.
-- Hardened the Windows signing/release workflow with SignPath retry handling for signed `.exe` and `.zip` artifacts.
+**Fixed**
+- Overlay: Restored controller navigation and lookup/mining controls while the subtitle sidebar is open, while keeping true modal dialogs blocking controller actions.
+- Tokenizer: Fixed subtitle annotation clearing so explanatory contrast endings like `んですけど` are excluded consistently across the shared tokenizer filter and annotation stage.
 
-## v0.5.0 (2026-03-08)
+<h2>v0.9.0 (2026-03-23)</h2>
 
-- Added the initial packaged Windows release.
-- Added Windows-native mpv window tracking, launcher/runtime plumbing, and packaged helper assets.
-- Improved close behavior so ending playback hides the visible overlay while the background app stays running.
-- Limited the native overlay outline/debug frame to debug mode on Windows.
+**Added**
+- Docs: Added a new WebSocket / Texthooker API and integration guide covering WebSocket payloads, custom client patterns, mpv plugin automation, and webhook-style relay examples. Linked from configuration and mining workflow docs for easier discovery.
 
-## v0.3.0 (2026-03-05)
+**Changed**
+- Launcher: Added an app-owned YouTube subtitle flow that pauses mpv, uses absPlayer-style YouTube timedtext parsing/conversion to download subtitle tracks, and injects them as external files before playback resumes.
+- Launcher: Changed YouTube subtitle startup to auto-load the best-available primary and secondary subtitle tracks at launch instead of forcing the picker modal first. Secondary subtitle failures no longer block playback resume.
+- Launcher: Added `Ctrl+Alt+C` as the default keybinding to manually open the YouTube subtitle picker during active YouTube playback.
+- Launcher: Added yt-dlp metadata probing so YouTube playback and immersion tracking record canonical video title and channel metadata.
+- Launcher: Stopped forcing `--ytdl-raw-options=` before user-provided mpv options so existing YouTube cookie integrations in user `--args` are no longer clobbered.
+- Launcher: Disabled mpv native YouTube subtitle auto-loading for the app-owned flow so injected external subtitle files remain authoritative.
+- Launcher: Added OSD status messages for YouTube playback startup, subtitle acquisition, and subtitle loading so the flow stays visible before and during the picker.
+- Subtitle Sidebar: Added startup-auto-open controls and resume positioning improvements so the sidebar jumps directly to the first resolved active cue.
+- Subtitle Sidebar: Improved subtitle prefetch and embedded overlay passthrough sync so sidebar and overlay subtitle states stay consistent across media transitions.
+- Subtitle Sidebar: Updated scroll handling, embedded layout styling, and active-cue visual behavior.
+- Stats: Stats Library tab now displays YouTube video title, channel name, and channel thumbnail for YouTube media entries, with retry logic to fill in metadata that arrives after initial load.
+
+**Fixed**
+- Launcher: Fixed Anki media mining for mpv YouTube streams by unwrapping the stream URL so audio and screenshot capture work correctly for YouTube playback sessions.
+- Immersion: Fixed YouTube media path handling in the immersion runtime and tracking so YouTube sessions record correct media references, AniList guessing skips YouTube URLs, and post-watch state transitions do not fire for YouTube media.
+- Launcher: Fixed startup-launched YouTube playback so primary subtitle overlay updates continue after auto-load completes.
+- Launcher: Fixed auto-loaded YouTube primary subtitles so parsed cues appear in the subtitle sidebar without needing a manual picker retry.
+- Launcher: Fixed the YouTube picker to guard against duplicate subtitle submissions and tightened YouTube URL detection so follow-up runtime flows only treat real YouTube hosts as YouTube playback.
+- Launcher: Fixed primary subtitle failure notifications being shown while app-owned YouTube subtitle probing and downloads are still in flight.
+- Launcher: Preserved existing authoritative YouTube subtitle tracks when available; downloaded tracks are used only to fill missing sides, and native mpv secondary subtitle rendering is hidden so the overlay remains the sole secondary display.

+- IPC: Added sidebar snapshot plumbing between renderer and main process for overlay/sidebar synchronization.
+

+<summary>v0.7.x</summary>
+
+<h2>v0.7.0 (2026-03-19)</h2>
+
+**Added**
+- Immersion: Added Mine Word, Mine Sentence, and Mine Audio buttons to word detail example lines in the stats dashboard.
+- Immersion: Mine Word creates a full Yomitan card (definition, reading, pitch accent) via the hidden search page bridge, then enriches with sentence audio, screenshot, and metadata extracted from the source video.
+- Immersion: Mine Sentence and Mine Audio create cards directly with appropriate Lapis/Kiku flags, sentence highlighting, and media from the source file.
+- Immersion: Media generation (audio + image/AVIF) runs in parallel and respects all AnkiConnect config options.
+- Immersion: Added word exclusion list to the Vocabulary tab with localStorage persistence and a management modal.
+- Immersion: Fixed truncated readings in the frequency rank table (e.g. お前 now shows おまえ instead of まえ).
+- Immersion: Clicking a bar in the Top Repeated Words chart now opens the word detail panel.
+- Immersion: Secondary subtitle text is now stored alongside primary subtitle lines for use as translation when mining cards from the stats page.
+- Stats: Added `subminer stats -b` to start or reuse a dedicated background stats server without blocking normal SubMiner instances.
+- Stats: Added `subminer stats -s` to stop the dedicated background stats server without closing browser tabs.
+- Stats: Stats server startup now reuses a running background stats daemon instead of trying to bind a second local server in another SubMiner instance.
+- Launcher: Added launcher passthrough for `-a/--args` so mpv receives raw extra launch flags (`--fs`, `--ytdl-format`, custom audio/video settings, etc.) from the `subminer` command.
+- Launcher: Added `subminer stats` to launch the local stats dashboard, force-start the stats server on demand, and open the dashboard in your browser.
+- Launcher: Added `subminer stats cleanup` to backfill vocabulary metadata and prune stale or excluded immersion rows on demand.
+- Launcher: Added `stats.autoOpenBrowser` so browser launch after `subminer stats` can be enabled or disabled explicitly.
+- Immersion: Added a local stats dashboard for immersion tracking with Overview, Anime, Trends, Vocabulary, and Sessions views.
+- Immersion: Added anime progress, episode completion, Anki card links, and occurrence drill-down across the stats dashboard.
+- Immersion: Added richer session timelines with new-word activity, cumulative totals, and pause/seek/card event markers.
+- Immersion: Added completed-episodes and completed-anime totals to the Overview tracking snapshot.
+
+**Changed**
+- Anki: Changed known-word cache settings to live under `ankiConnect.knownWords` instead of mixing them into `ankiConnect.nPlusOne`.
+- Anki: Kept legacy `ankiConnect.nPlusOne` known-word keys and older `ankiConnect.behavior.nPlusOne*` keys as deprecated compatibility fallbacks.
+- Stats: Added session deletion to the Sessions tab with the same confirmation prompt used by anime episode/session deletes, and removed all associated session rows from the stats database.
+- Immersion: Kept immersion tracking history by default while preserving daily/monthly rollup maintenance.
+- Immersion: Added exact lifetime summary reads for overview/anime/media stats so dashboard totals no longer depend on rescanning raw telemetry.
+- Immersion: Reduced tracker storage overhead by removing duplicated subtitle text from subtitle-line event payloads.
+- Immersion: Deduplicated episode cover-art blobs through a shared blob store and updated cover-art reads/writes to resolve shared images correctly.
+- Immersion: Added indexes for large-history session, telemetry, vocabulary, kanji, and cover-art queries to keep dashboard reads fast as the SQLite database grows.
+- Immersion: Renamed the stats dashboard's Anime tab to Library so the media browser label matches non-anime sources like YouTube and other yt-dlp-backed content.
+- Anilist: Standardized episode completion threshold by introducing `DEFAULT_MIN_WATCH_RATIO` and using it for both local watched state transitions and AniList post-watch progress updates.
+- Anilist: Episode auto-marking now uses the same threshold as AniList (`85%`), removing divergent completion behavior.
+- Overlay: Excluded interjections and sound-effect tokens from subtitle annotation styling so they no longer inherit misleading lexical highlight treatment while still remaining visible and hoverable as plain subtitle tokens.
+- Overlay: Expanded subtitle annotation noise filtering to also strip annotation metadata from standalone grammar-only helper tokens such as particles, auxiliaries, adnominals, common explanatory endings like `んです` / `のだ`, and merged trailing quote-particle forms like `...って` while keeping them tokenized for hover lookup.
+
+**Fixed**
+- Launcher: Fixed mpv Lua plugin binary auto-detection on Linux to also search `/usr/bin/subminer` and `/usr/local/bin/subminer` (lowercase), matching the conventional Unix wrapper name used by packaged installs such as the AUR package.
+- Stats: Fixed the in-app stats overlay so it connects to the configured `stats.serverPort` instead of falling back to the default port.
+- Overlay: Fixed subtitle frequency tagging for merged lookup-backed tokens like `陰に` by falling back to exact surface-form Yomitan frequencies when the normalized headword lookup misses.
+- Overlay: Fixed MeCab merged-token position mapping across line breaks so merged content-plus-particle tokens like `陰に` keep their matched Yomitan frequency instead of inheriting shifted POS tags.
+- Overlay: Fixed grouped frequency parsing in both Yomitan and fallback frequency-dictionary lookups so display values like `118,121` use the leading rank instead of collapsing the rank and occurrence count into `118121`.
+- Overlay: Fixed frequency-rank ingestion to ignore Yomitan dictionaries explicitly marked `occurrence-based`, so raw occurrence counts are no longer treated as subtitle rank values.
+- Overlay: Fixed inflected headword frequency tagging to prefer ranks from the selected Yomitan `termsFind` popup entry itself, ordered by configured dictionary priority, so forms like `潜み` use primary-dictionary ranks like `4073` before falling back to lower-priority raw lemma metadata such as `CC100`.
+- Overlay: Fixed annotation-stage frequency filtering so exact kanji noun tokens like `者` keep their matched rank even when MeCab labels them `名詞/非自立`, instead of dropping the highlight after scan-time frequency lookup succeeds.
+- Anki: Fixed repeated character-dictionary startup work by scheduling auto-sync only from mpv media-path changes instead of also re-triggering it from connection and media-title events for the same title.
+- Overlay: Fixed macOS fullscreen overlay stability by keeping the passive visible overlay from stealing focus, re-raising the overlay window when reasserting its macOS topmost level, and tolerating one transient macOS tracker/helper miss before hiding the overlay.
+- Overlay: Kept subtitle tokenization warmup one-shot for the lifetime of the app so later fullscreen/media churn on macOS does not replay the startup warmup gate after the first file is ready.
+- Overlay: Added a bounded macOS tracker loss-grace window so fullscreen enter/leave transitions do not immediately hide and reload the overlay when the helper briefly loses the mpv window.
+- Overlay: Skipped subtitle/tokenization refresh invalidation on character-dictionary auto-sync completion when the dictionary was already current, preventing startup flash/reload loops on unchanged media.
+- Stats: Fixed session stats so known-word counts track real known-word occurrences without collapsing subtitle-line gaps.
+- Stats: Fixed session word totals in session-facing stats views to prefer token counts when available, preventing known words from exceeding total words in the session chart.
+- Stats: Fixed the stats Vocabulary tab blank-screen regression caused by a hook-order crash after vocabulary data finished loading.
+- Anki: Fixed card-mine OSD feedback so the final mine result stops the Anki spinner first, then shows a single-line `✓`/`x` status without being overwritten by a later spinner tick.
+- Stats: Removed the misleading `New words` series from expanded session charts; session detail now shows only the real total-word and known-word lines.
+- Stats: Restored the cross-anime word table behavior in stats vocabulary surfaces so shared vocabulary entries no longer disappear or merge incorrectly across related media.
+- Stats: `subminer stats -b` now runs as a standalone background stats daemon instead of reusing the main SubMiner app process, so the overlay app can still be launched separately for normal video watching.
+- Stats: Dashboard word mining still works against the background daemon by using a short-lived hidden helper for the Yomitan add-note flow.
+- Stats: Load full session timelines by default in stats session detail views so long sessions preserve complete telemetry history instead of being truncated by a fixed sample limit.
+- Stats: Replaced heuristic stats word counts with Yomitan token counts, so session, media, anime, and trend subtitle totals now come directly from parsed subtitle tokens.
+- Stats: Updated stats UI labels and lookup-rate copy to refer to tokens instead of words where those counts are shown.
+- Overlay: Reduced repeated `Overlay loading...` popups on macOS when fullscreen tracker flaps briefly hide and recover the visible overlay.
+- Stats: Scaled expanded session-detail known-word charts to the session's actual percentage range so small changes no longer render as a nearly flat line.
+- Jlpt: Reduced JLPT dictionary startup log noise by summarizing duplicate surface-form collisions instead of logging one line per duplicate entry.

+
+**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.

+- 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.

+- Supported prerelease channels are `beta` and `rc`, with versions like `0.11.3-beta.1` and `0.11.3-rc.1`.
 - Pass `--date` explicitly when you want the release stamped with the local cut date; otherwise the generator uses the current ISO date, which can roll over to the next UTC day late at night.
 - `changelog:check` now rejects tag/package version mismatches.
+- `changelog:prerelease-notes` also rejects tag/package version mismatches and writes `release/prerelease-notes.md` without mutating tracked changelog files.
 - `changelog:build` generates `CHANGELOG.md` + `release/release-notes.md` and removes the released `changes/*.md` fragments.
 - In the same way, the release workflow now auto-runs `changelog:build` when it detects unreleased `changes/*.md` on a tag-based run, then verifies and publishes.
 - Do not tag while `changes/*.md` fragments still exist.
+- Prerelease tags intentionally keep `changes/*.md` fragments in place so multiple prereleases can reuse the same cumulative pending notes until the final stable cut.
 - If you need to repair a published release body (for example, a prior version’s section was omitted), regenerate notes from `CHANGELOG.md` and re-edit the release with `gh release edit --notes-file`.
+- Prerelease tags are handled by `.github/workflows/prerelease.yml`, which always publishes a GitHub prerelease with all current release platforms and never runs the AUR sync job.
 - Tagged release workflow now also attempts to update `subminer-bin` on the AUR after GitHub Release publication.
 - AUR publish is best-effort: the workflow retries transient SSH clone/push failures, then warns and leaves the GitHub Release green if AUR still fails. Follow up with a manual `git push aur master` from the AUR checkout when needed.
 - Required GitHub Actions secret: `AUR_SSH_PRIVATE_KEY`. Add the matching public key to your AUR account before relying on the automation.

+# Library Summary Replaces Per-Day Trends — Design
+
+**Status:** Draft
+**Date:** 2026-04-09
+**Scope:** `stats/` frontend, `src/core/services/immersion-tracker/query-trends.ts` backend
+
+## Problem
+
+The "Library — Per Day" section on the stats Trends tab (`stats/src/components/trends/TrendsTab.tsx:224-254`) renders six stacked-area charts — Videos, Watch Time, Cards, Words, Lookups, and Lookups/100w, each broken down per title per day.
+
+In practice these charts are not useful:
+
+- Most titles only have activity on one or two days in a window, so they render as isolated bumps on a noisy baseline.
+- Stacking 7+ titles with mostly-zero days makes individual lines hard to follow.
+- The top "Activity" and "Period Trends" sections already answer "what am I doing per day" globally.
+- The "Library — Cumulative" section directly below already answers "which titles am I progressing through" with less noise.
+
+The per-day section occupies significant vertical space without carrying its weight, and the user has confirmed it should be replaced.
+
+## Goal
+
+Replace the six per-day stacked charts with a single "Library — Summary" section that surfaces per-title aggregate statistics over the selected date range. The new view should make it trivially easy to answer: "For the selected window, which titles am I spending time on, how much mining output have they produced, and how efficient is my lookup rate on each?"
+
+## Non-goals
+
+- Changing the "Library — Cumulative" section (stays as-is).
+- Changing the "Activity", "Period Trends", or "Patterns" sections.
+- Adding a new API endpoint — the existing dashboard endpoint is extended in place.
+- Renaming internal `anime*` data-model identifiers (`animeId`, `imm_anime`, etc.). Those stay per the convention established in `c5e778d7`; only new fields/types/user-visible strings use generic "title"/"library" wording.
+- Supporting a true all-time library view on the Trends tab. If that's ever wanted, it belongs on a different tab.
+
+## Solution Overview
+
+Delete the "Library — Per Day" section. In its place, add "Library — Summary", composed of:
+
+1. A horizontal-bar leaderboard chart of watch time per title (top 10, descending).
+2. A sortable table of every title with activity in the selected window, with columns: Title, Watch Time, Videos, Sessions, Cards, Words, Lookups, Lookups/100w, Date Range.
+
+Both controls are scoped to the top-of-page date range selector. The existing shared Anime Visibility filter continues to work — it now gates Summary + Cumulative instead of Per-Day + Cumulative.
+
+## Backend
+
+### New type
+
+Add to `stats/src/types/stats.ts` and the backend query module:
+
+```ts
+type LibrarySummaryRow = {
+  title: string;              // display title — anime series, YouTube video title, etc.
+  watchTimeMin: number;       // sum(total_active_min) across the window
+  videos: number;             // distinct video_id count
+  sessions: number;           // session count from imm_sessions
+  cards: number;              // sum(total_cards)
+  words: number;              // sum(total_tokens_seen)
+  lookups: number;            // sum(lookup_count) from imm_sessions
+  lookupsPerHundred: number | null; // lookups / words * 100, null when words == 0
+  firstWatched: number;       // min(rollup_day) as epoch day, within the window
+  lastWatched: number;        // max(rollup_day) as epoch day, within the window
+};
+```
+
+### Query changes in `src/core/services/immersion-tracker/query-trends.ts`
+
+- Add `librarySummary: LibrarySummaryRow[]` to `TrendsDashboardQueryResult`.
+- Populate it from a single aggregating query over `imm_daily_rollups` joined to `imm_videos` → `imm_anime`, filtered by `rollup_day` within the selected window. Session count and lookup count come from `imm_sessions` aggregated by `video_id` and then grouped by the parent library entry. Use a single query (or at most two joined/unioned) — no N+1.
+- `imm_anime` is the generic library-grouping table; anime series, YouTube videos, and yt-dlp imports all land there. The internal table name stays `imm_anime`; only the new field uses generic naming.
+- Return rows pre-sorted by `watchTimeMin` descending so the leaderboard is zero-cost and the table default sort matches.
+- Emit `lookupsPerHundred: null` when `words == 0`.
+
+### Removed from API response
+
+Drop the entire `animePerDay` field from `TrendsDashboardQueryResult` (both backend in `src/core/services/immersion-tracker/query-trends.ts` and frontend in `stats/src/types/stats.ts`).
+
+Internally, the existing helpers (`buildPerAnimeFromDailyRollups`, `buildEpisodesPerAnimeFromDailyRollups`) are still used as intermediates to build `animeCumulative.*` via `buildCumulativePerAnime`. Keep those helpers — just scope their output to local variables inside `getTrendsDashboard` instead of exposing them on the response. The `buildPerAnimeFromSessions` call for lookups and the `buildLookupsPerHundredPerAnime` helper become unused and can be deleted.
+
+Before removing `animePerDay` from the frontend type, verify no other file under `stats/src/` references it. Based on current inspection, only `TrendsTab.tsx` and `stats/src/types/stats.ts` touch it.
+
+## Frontend
+
+### New component: `stats/src/components/trends/LibrarySummarySection.tsx`
+
+Owns the header, leaderboard chart, visibility-filtered data, and the table. Keeps `TrendsTab.tsx` from growing. Component props: `{ rows: LibrarySummaryRow[]; hiddenTitles: ReadonlySet<string>; windowStart: Date; windowEnd: Date }`.
+
+Internal state: `useState<{ column: ColumnId; direction: 'asc' | 'desc' }>` for sort, defaulting to `{ column: 'watchTimeMin', direction: 'desc' }`.
+
+### Layout
+
+Replaces `TrendsTab.tsx:224-254`:
+
+```
+[SectionHeader: "Library — Summary"]
+[AnimeVisibilityFilter — unchanged, shared with Cumulative below]
+[Card, col-span-full: Leaderboard — horizontal bar chart, ~260px tall]
+[Card, col-span-full: Sortable table, auto height up to ~480px with internal scroll]
+```
+
+Both cards use the existing chart/card wrapper styling.
+
+### Leaderboard chart
+
+- Recharts horizontal bar chart (matches the rest of the page — existing charts use `recharts`, not ECharts).
+- Top 10 titles by watch time. If fewer titles have activity, render what's there.
+- Y-axis: title (category), truncated with ellipsis at container width; full title visible in the Recharts tooltip.
+- X-axis: minutes (number).
+- Use `layout="vertical"` with `YAxis dataKey="title" type="category"` and `XAxis type="number"`.
+- Single series color: `#8aadf4` (matching the existing Watch Time color).
+- Reuse `CHART_DEFAULTS`, `CHART_THEME`, `TOOLTIP_CONTENT_STYLE` from `stats/src/lib/chart-theme.ts` so theming matches the rest of the dashboard.
+- Chart order is fixed at watch-time desc regardless of table sort — the leaderboard's meaning is fixed.
+
+### Table
+
+- Plain HTML `<table>` with Tailwind classes. No new deps.
+- Columns, in order:
+  1. **Title** — left-aligned, sticky, truncated with ellipsis, full title on hover.
+  2. **Watch Time** — formatted `Xh Ym` when ≥60 min, else `Xm`.
+  3. **Videos** — integer.
+  4. **Sessions** — integer.
+  5. **Cards** — integer.
+  6. **Words** — integer.
+  7. **Lookups** — integer.
+  8. **Lookups/100w** — one decimal place, `—` when null.
+  9. **Date Range** — `Mon D → Mon D` using the title's `firstWatched` / `lastWatched` within the window.
+- Click a column header to sort; click again to reverse. Visual arrow on the active column.
+- Numeric columns right-aligned.
+- Null `lookupsPerHundred` sorts as the lowest value in both directions (consistent with "no data").
+- Row hover highlight; no row click action (read-only view).
+- Empty state: "No library activity in the selected window."
+
+### Visibility filter integration
+
+Hiding a title via `AnimeVisibilityFilter` removes it from both the leaderboard and the table. The filter's set of available titles is built from the union of titles that appear in `librarySummary` and the existing `animeCumulative.*` arrays (matches current behavior in `buildAnimeVisibilityOptions`).
+
+### `TrendsTab.tsx` changes
+
+- Remove the `filteredEpisodesPerAnime`, `filteredWatchTimePerAnime`, `filteredCardsPerAnime`, `filteredWordsPerAnime`, `filteredLookupsPerAnime`, `filteredLookupsPerHundredPerAnime` locals.
+- Remove the six `<StackedTrendChart>` calls in the "Library — Per Day" section.
+- Remove the `<SectionHeader>Library — Per Day</SectionHeader>` and the `<AnimeVisibilityFilter>` from that position.
+- Insert `<SectionHeader>Library — Summary</SectionHeader>` + `<AnimeVisibilityFilter>` + `<LibrarySummarySection>` in the same place.
+- Update `buildAnimeVisibilityOptions` input to use `librarySummary` titles instead of the six dropped `animePerDay.*` arrays.
+
+## Data flow
+
+1. `useTrends(range, groupBy)` calls `/api/stats/trends/dashboard`.
+2. Response now includes `librarySummary` (sorted by watch time desc).
+3. `TrendsTab` holds the shared `hiddenAnime` set (unchanged).
+4. `LibrarySummarySection` receives `librarySummary` + `hiddenAnime`, filters out hidden rows, renders the leaderboard from the top-10 slice of the filtered list, renders the table from the filtered list with local sort state applied.
+5. Date-range selector changes trigger a new fetch; `groupBy` toggle does not affect the summary section (it's always window-total).
+
+## Edge cases
+
+- **No activity in window:** Section renders header + empty-state card. Leaderboard card hidden. Visibility filter hidden.
+- **One title only:** Leaderboard renders a single bar; table renders one row. No special-casing.
+- **Title with zero words but non-zero lookups:** `lookupsPerHundred` is `null`, rendered as `—`. Sort treats null as lowest.
+- **Title with zero cards/lookups/words but non-zero watch time:** Normal zero rendering, still shown.
+- **Very long titles:** Ellipsis in chart y-axis labels and table title column; full title in `title` attribute / ECharts tooltip.
+- **Mixed sources (anime + YouTube):** No special case — both land in `imm_anime` and are grouped uniformly.
+
+## Testing
+
+### Backend (`query-trends.ts`)
+
+New unit tests, following the existing pattern:
+
+1. Empty window returns `librarySummary: []`.
+2. Single title with a few rollups: all aggregates are correct; `firstWatched`/`lastWatched` match the bounding days within the window.
+3. Multiple titles: rows returned sorted by watch time desc.
+4. Mixed sources (anime-style + YouTube-style entries in `imm_anime`): both appear in the summary with their own aggregates.
+5. Title with `words == 0`: `lookupsPerHundred` is `null`.
+6. Date range excludes some rollups: excluded rollups are not counted; `firstWatched`/`lastWatched` reflect only within-window activity.
+7. `sessions` and `lookups` come from `imm_sessions`, not `imm_daily_rollups`, and are correctly attributed to the parent library entry.
+
+### Frontend
+
+- Existing Trends tab smoke test should continue to pass after wiring.
+- Optional: a targeted render test for `LibrarySummarySection` (empty state, single title, sort toggle, visibility filter interaction). Not required for merge if the smoke test exercises the happy path.
+
+## Release / docs
+
+- One fragment in `changes/*.md` summarizing the replacement.
+- No user-facing docs (`docs-site/`) changes unless the per-day section was documented there — verify during implementation.

+# Stats Dashboard Feedback Pass — Design
+
+Date: 2026-04-09
+Scope: Stats dashboard UX follow-ups from user feedback (items 1–7).
+Delivery: **Single PR**, broken into logically scoped commits.
+
+## Goals
+
+Address seven concrete pieces of feedback against the Statistics menu:
+
+1. Library — collapse episodes behind a per-series dropdown.
+2. Sessions — roll up multiple sessions of the same episode within a day.
+3. Trends — add a 365d range option.
+4. Library — delete an episode (video) from its detail view.
+5. Vocabulary — tighten spacing between word and reading in the Top 50 table.
+6. Episode detail — hide cards whose Anki notes have been deleted.
+7. Trend/watch charts — add gridlines, fix tick legibility, unify theming.
+
+Out of scope for this pass: English-token ingestion cleanup and Overview stat-card drill-downs (feedback items 8 and 9). Those require a larger design decision and a migration respectively.
+
+## Files touched (inventory)
+
+Dashboard (`stats/src/`):
+- `components/library/LibraryTab.tsx` — collapsible groups (item 1).
+- `components/library/MediaDetailView.tsx`, `components/library/MediaHeader.tsx` — delete-episode action (item 4).
+- `components/sessions/SessionsTab.tsx`, `components/library/MediaSessionList.tsx` — episode rollup (item 2).
+- `components/trends/DateRangeSelector.tsx`, `hooks/useTrends.ts`, `lib/api-client.ts`, `lib/api-client.test.ts` — 365d (item 3).
+- `components/vocabulary/FrequencyRankTable.tsx` — word/reading column collapse (item 5).
+- `components/anime/EpisodeDetail.tsx` — filter deleted Anki cards (item 6).
+- `components/trends/TrendChart.tsx`, `components/trends/StackedTrendChart.tsx`, `components/overview/WatchTimeChart.tsx`, `lib/chart-theme.ts` — chart clarity (item 7).
+- New file: `stats/src/lib/session-grouping.ts` + `session-grouping.test.ts`.
+
+Backend (`src/core/services/`):
+- `immersion-tracker/query-trends.ts` — extend `TrendRange` and `TREND_DAY_LIMITS` (item 3).
+- `immersion-tracker/__tests__/query.test.ts` — 365d coverage (item 3).
+- `stats-server.ts` — passthrough if range validation lives here (check before editing).
+- `__tests__/stats-server.test.ts` — 365d coverage (item 3).
+
+## Commit plan
+
+One PR, one feature per commit. Order picks low-risk mechanical changes first so failures in later commits don't block merging of earlier ones.
+
+1. `feat(stats): add 365d range to trends dashboard` (item 3)
+2. `fix(stats): tighten word/reading column in Top 50 table` (item 5)
+3. `fix(stats): hide cards deleted from Anki in episode detail` (item 6)
+4. `feat(stats): delete episode from library detail view` (item 4)
+5. `feat(stats): collapsible series groups in library` (item 1)
+6. `feat(stats): roll up same-episode sessions within a day` (item 2)
+7. `feat(stats): gridlines and unified theme for trend charts` (item 7)
+
+Each commit must pass `bun run typecheck`, `bun run test:fast`, and any change-specific checks listed below.
+
+---
+
+## Item 1 — Library collapsible series groups
+
+### Current behavior
+
+`LibraryTab.tsx` groups media via `groupMediaLibraryItems` and always renders the full grid of `MediaCard`s beneath each group header.
+
+### Target behavior
+
+Each group header becomes clickable. Groups with `items.length > 1` default to **collapsed**; single-video groups stay expanded (collapsing them would be visual noise).
+
+### Implementation
+
+- State: `const [collapsedGroups, setCollapsedGroups] = useState<Set<string>>(...)`. Initialize from `grouped` where `items.length > 1`.
+- Toggle helper: `toggleGroup(key: string)` adds/removes from the set.
+- Group header: wrap in a `<button>` with `aria-expanded` and a chevron icon (`▶`/`▼`). Keep the existing cover + title + subtitle layout inside the button.
+- Children grid is conditionally rendered on `!collapsedGroups.has(group.key)`.
+- Header summary (`N videos · duration · cards`) stays visible in both states so collapsed groups remain informative.
+
+### Tests
+
+- New `LibraryTab.test.tsx` (if not already present — check first) covering:
+  - Multi-video group renders collapsed on first mount.
+  - Single-video group renders expanded on first mount.
+  - Clicking the header toggles visibility.
+  - Header summary is visible in both states.
+
+---
+
+## Item 2 — Sessions episode rollup within a day
+
+### Current behavior
+
+`SessionsTab.tsx:10-24` groups sessions by day label only (`formatSessionDayLabel(startedAtMs)`). Multiple sessions of the same episode on the same day show as independent rows. `MediaSessionList.tsx` has the same problem inside the library detail view.
+
+### Target behavior
+
+Within each day, sessions with the same `videoId` collapse into one parent row showing combined totals. A chevron reveals the individual sessions. Single-session buckets render flat (no pointless nesting).
+
+### Implementation
+
+- New helper in `stats/src/lib/session-grouping.ts`:
+  ```ts
+  export interface SessionBucket {
+    key: string;              // videoId as string, or `s-${sessionId}` for singletons
+    videoId: number | null;
+    sessions: SessionSummary[];
+    totalActiveMs: number;
+    totalCardsMined: number;
+    representativeSession: SessionSummary; // most recent, for header display
+  }
+  export function groupSessionsByVideo(sessions: SessionSummary[]): SessionBucket[];
+  ```
+  Sessions missing a `videoId` become singleton buckets.
+
+- `SessionsTab.tsx`: after day grouping, pipe each `daySessions` through `groupSessionsByVideo`. Render each bucket:
+  - `sessions.length === 1`: existing `SessionRow` behavior, unchanged.
+  - `sessions.length >= 2`: render a **bucket row** that looks like `SessionRow` but shows combined totals and session count (e.g. `3 sessions · 1h 24m · 12 cards`). Chevron state stored in a second `Set<string>` on bucket key. Expanded buckets render the child `SessionRow`s indented (`pl-8`) beneath the header.
+- `MediaSessionList.tsx`: within the media detail view, a single video's sessions are all the same `videoId` by definition — grouping here is by day only, and within a day multiple sessions render nested under a day header. Re-use the same visual pattern; factor the bucket row into a shared `SessionBucketRow` component.
+
+### Delete semantics
+
+- Deleting a bucket header offers "Delete all N sessions in this group" (reuse `confirmDayGroupDelete` pattern with a bucket-specific message, or add `confirmBucketDelete`).
+- Deleting an individual session from inside an expanded bucket keeps the existing single-delete flow.
+
+### Tests
+
+- `session-grouping.test.ts`:
+  - Empty input → empty output.
+  - All unique videos → N singleton buckets.
+  - Two sessions same videoId → one bucket with correct totals and representative (most recent start time).
+  - Missing videoId → singleton bucket keyed by sessionId.
+- `SessionsTab.test.tsx` (extend or add) verifying the rendered bucket rows expand/collapse and delete hooks fire with the right ID set.

+
+## Item 3 — 365d trends range
+
+### Backend
+
+`src/core/services/immersion-tracker/query-trends.ts`:
+- `type TrendRange = '7d' | '30d' | '90d' | '365d' | 'all';`
+- Add `'365d': 365` to `TREND_DAY_LIMITS`.
+- `getTrendDayLimit` picks up the new key automatically because of the `Exclude<TrendRange, 'all'>` generic.
+
+`src/core/services/stats-server.ts`:
+- Search for any hardcoded range validation (e.g. allow-list in the trends route handler) and extend it.
+
+### Frontend
+
+- `hooks/useTrends.ts`: widen the `TimeRange` union.
+- `components/trends/DateRangeSelector.tsx`: add `'365d'` to the options list. Display label stays as `365d`.
+- `lib/api-client.ts` / `api-client.test.ts`: if the client validates ranges, add `365d`.
+
+### Tests
+
+- `query.test.ts`: extend the existing range table to cover `365d` returning 365 days of data.
+- `stats-server.test.ts`: ensure the route accepts `range=365d`.
+- `api-client.test.ts`: ensure the client emits the new range.
+
+### Change-specific checks
+
+- `bun run test:config` is not required here (no schema/defaults change).
+- Run `bun run typecheck` + `bun run test:fast`.
+
+---
+
+## Item 4 — Delete episode from library detail
+
+### Current behavior
+
+`MediaDetailView.tsx` provides session-level delete only. The backend `deleteVideo` exists (`query-maintenance.ts:509`), the API is exposed at `stats-server.ts:559`, and `api-client.deleteVideo` is already wired (`stats/src/lib/api-client.ts:146`). `EpisodeList.tsx:46` already uses it from the anime tab.
+
+### Target behavior
+
+A "Delete Episode" action in `MediaHeader` (top-right, small, `text-ctp-red`), gated by `confirmEpisodeDelete(title)`. On success, call `onBack()` and make sure the parent `LibraryTab` refetches.
+
+### Implementation
+
+- Add an `onDeleteEpisode?: () => void` prop to `MediaHeader` and render the button only if provided.
+- In `MediaDetailView`:
+  - New handler `handleDeleteEpisode` that calls `apiClient.deleteVideo(videoId)`, then `onBack()`.
+  - Reuse `confirmEpisodeDelete` from `stats/src/lib/delete-confirm.ts`.
+- In `LibraryTab`:
+  - `useMediaLibrary` returns fresh data on mount. The simplest fix: pass a `refresh` function from the hook (extend the hook if it doesn't already expose one) and call it when the detail view signals back.
+  - Alternative: force a remount by incrementing a `libraryVersion` key on the library list. Prefer `refresh` for clarity.
+
+### Tests
+
+- Extend the existing `MediaDetailView.test.tsx`: mock `apiClient.deleteVideo`, click the new button, confirm `onBack` fires after success.
+- `useMediaLibrary.test.ts`: if we add a `refresh` method, cover it.
+
+---
+
+## Item 5 — Vocabulary word/reading column collapse
+
+### Current behavior
+
+`FrequencyRankTable.tsx:110-144` uses a 5-column table: `Rank | Word | Reading | POS | Seen`. Word and Reading are auto-sized, producing a large gap.
+
+### Target behavior
+
+Merge Word + Reading into a single column titled "Word". Reading sits immediately after the headword in a muted, smaller style.
+
+### Implementation
+
+- Drop the `<th>Reading</th>` header and cell.
+- Word cell becomes:
+  ```tsx
+  <td className="py-1.5 pr-3">
+    <span className="text-ctp-text font-medium">{w.headword}</span>
+    {reading && (
+      <span className="text-ctp-subtext0 text-xs ml-1.5">
+        【{reading}】
+      </span>
+    )}
+  </td>
+  ```
+  where `reading = fullReading(w.headword, w.reading)` and differs from `headword`.
+- Keep `fullReading` import from `reading-utils`.
+
+### Tests
+
+- Extend `FrequencyRankTable.test.tsx` (if present — otherwise add a focused test) to assert:
+  - Headword renders.
+  - Reading renders when different from headword.
+  - Reading does not render when equal to headword.
+
+---
+
+## Item 6 — Hide Anki-deleted cards in Cards Mined
+
+### Current behavior
+
+`EpisodeDetail.tsx:109-147` iterates `cardEvents`, fetches note info via `ankiNotesInfo(allNoteIds)`, and for each `noteId` renders a row even if no matching `info` came back — the user sees an empty word with an "Open in Anki" button that leads nowhere.
+
+### Target behavior
+
+After `ankiNotesInfo` resolves:
+- Drop `noteId`s that are not in the resolved map.
+- Drop `cardEvents` whose `noteIds` list was non-empty but is now empty after filtering.
+- Card events with a positive `cardsDelta` but no `noteIds` (legacy rollup path) still render as `+N cards` — we have no way to cross-reference them, so leave them alone.
+
+### Implementation
+
+- Compute `filteredCardEvents` as a `useMemo` depending on `data.cardEvents` and `noteInfos`.
+- Iterate `filteredCardEvents` instead of `cardEvents` in the render.
+- Surface a subtle note (optional, muted) "N cards hidden (deleted from Anki)" at the end of the list if any were filtered — helps the user understand why counts here diverge from session totals. Final decision on the note can be made at PR review; default: **show it**.
+
+### Tests
+
+- Add a test in `EpisodeDetail.test.tsx` (add the file if not present) that stubs `ankiNotesInfo` to return only a subset of notes and verifies the missing ones are not rendered.
+
+### Other call sites
+
+- Grep so far shows `ankiNotesInfo` is only used in `EpisodeDetail.tsx`. Re-verify before landing the commit; if another call site appears, apply the same filter.
+
+---
+
+## Item 7 — Trend/watch chart clarity pass
+
+### Current behavior
+
+`TrendChart.tsx`, `StackedTrendChart.tsx`, and `WatchTimeChart.tsx` render Recharts components with:
+- No `CartesianGrid` → no horizontal reference lines.
+- 9px axis ticks → borderline unreadable.
+- Height 120 → cramped.
+- Tooltip uses raw labels (`04/04` etc.).
+- No shared theme object; each chart redefines colors and tooltip styles inline.
+
+`stats/src/lib/chart-theme.ts` already exists and currently exports a single `CHART_THEME` constant with tick/tooltip colors and `barFill`. It will be extended, not replaced, to preserve existing consumers.
+
+### Target behavior
+
+All three charts share a theme, have horizontal gridlines, readable ticks, and sensible tooltips.
+
+### Implementation
+
+Extend `stats/src/lib/chart-theme.ts` with the additional shared defaults (keeping the existing `CHART_THEME` export intact so current consumers don't break):
+```ts
+export const CHART_THEME = {
+  tick: '#a5adcb',
+  tooltipBg: '#363a4f',
+  tooltipBorder: '#494d64',
+  tooltipText: '#cad3f5',
+  tooltipLabel: '#b8c0e0',
+  barFill: '#8aadf4',
+  grid: '#494d64',
+  axisLine: '#494d64',
+} as const;
+
+export const CHART_DEFAULTS = {
+  height: 160,
+  tickFontSize: 11,
+  margin: { top: 8, right: 8, bottom: 0, left: 0 },
+  grid: { strokeDasharray: '3 3', vertical: false },
+} as const;
+
+export const TOOLTIP_CONTENT_STYLE = {
+  background: CHART_THEME.tooltipBg,
+  border: `1px solid ${CHART_THEME.tooltipBorder}`,
+  borderRadius: 6,
+  color: CHART_THEME.tooltipText,
+  fontSize: 12,
+};
+```
+
+Apply to each chart:
+- Import `CartesianGrid` from recharts.
+- Insert `<CartesianGrid stroke={CHART_THEME.grid} {...CHART_DEFAULTS.grid} />` inside each chart container.
+- `<XAxis tick={{ fontSize: CHART_DEFAULTS.tickFontSize, fill: CHART_THEME.tick }} />` and equivalent `YAxis`.
+- `YAxis` gains `axisLine={{ stroke: CHART_THEME.axisLine }}`.
+- `ResponsiveContainer` height changes from 120 → `CHART_DEFAULTS.height`.
+- `Tooltip` `contentStyle` uses `TOOLTIP_CONTENT_STYLE`, and charts pass a `labelFormatter` when the label is a date key (e.g. show `Fri Apr 4`).
+
+### Unit formatters
+
+- `TrendChart` already accepts a `formatter` prop — extend usage sites to pass unit-aware formatters where they aren't already (`formatDuration`, `formatNumber`, etc.).
+
+### Tests
+
+- `chart-theme.test.ts` (if present — otherwise add a trivial snapshot to keep the shape stable).
+- `TrendChart` snapshot/render tests: no regression, gridline element present.
+
+---
+
+## Verification gate
+
+Before requesting code review, run:
+
+```
+bun run typecheck
+bun run test:fast
+bun run test:env
+bun run test:runtime:compat   # dist-sensitive check for the charts
+bun run build
+bun run test:smoke:dist
+```
+
+No docs-site changes are planned in this spec; if `docs-site/` ends up touched (e.g. screenshots), also run `bun run docs:test` and `bun run docs:build`.
+
+No config schema changes → `bun run test:config` and `bun run generate:config-example` are not required.
+
+## Risks and open questions
+
+- **MediaDetailView refresh**: `useMediaLibrary` may not expose a `refresh` function. If it doesn't, the simplest path is adding one; the alternative (keying a remount) works but is harder to test. Decide during implementation.
+- **Session bucket delete UX**: "Delete all N sessions in this group" is powerful. The copy must make it clear the underlying sessions are being removed, not just the grouping. Reuse `confirmBucketDelete` wording from existing confirm helpers if possible.
+- **Anki-deleted-cards hidden notice**: Showing a subtle "N cards hidden" footer is a call that can be made at PR review.
+- **Bucket delete helper**: `confirmBucketDelete` does not currently exist in `delete-confirm.ts`. Implementation either adds it or reuses `confirmDayGroupDelete` with bucket-specific wording — decide during the session-rollup commit.
+
+## Changelog entry
+
+User-visible PR → needs a fragment under `changes/*.md`. Suggested title:
+`Stats dashboard: collapsible series, session rollups, 365d trends, chart polish, episode delete.`
