fix: allow missing git in yomitan build; clean up README formatting

- Guard `getSourceState()` with `SUBMINER_YOMITAN_ALLOW_MISSING_GIT=1` escape hatch for environments without a git submodule
- Fix README requirements table column alignment and remove stray horizontal rule
- Update task-268 with follow-up CodeRabbit round notes and final summary

-description: "Use when working in the SubMiner repo and you need to verify code changes actually work. Covers targeted regression checks during debugging and pre-handoff verification, with cheap-first lane selection for config, docs, launcher/plugin, runtime-compat, and optional real-runtime escalation."
+name: 'subminer-change-verification'
+description: 'Compatibility shim. Canonical SubMiner change verification workflow now lives in the repo-local subminer-workflow plugin.'

-# SubMiner Change Verification
+# Compatibility Shim
 
-Use this skill for SubMiner code changes. Default to cheap, repo-native verification first. Escalate only when the changed behavior actually depends on Electron, mpv, overlay/window tracking, or other GUI-sensitive runtime behavior.
+Canonical source:
 
-## Scripts
+- `plugins/subminer-workflow/skills/subminer-change-verification/SKILL.md`
 
-- `scripts/classify_subminer_diff.sh`
-  - Emits suggested lanes and flags from explicit paths or current git changes.
-- `scripts/verify_subminer_change.sh`
-  - Runs selected lanes, captures artifacts, and writes a compact summary.
+Canonical helper scripts:
 
-If you need an explicit installed path, use the directory that contains this `SKILL.md`. The helper scripts live under:
+- `plugins/subminer-workflow/skills/subminer-change-verification/scripts/classify_subminer_diff.sh`
+- `plugins/subminer-workflow/skills/subminer-change-verification/scripts/verify_subminer_change.sh`
 
-```bash
-export SUBMINER_VERIFY_SKILL="<path-to-skill>"
-```
+When this shim is invoked:
 
-## Default workflow
-
-1. Inspect the changed files or user-requested area.
-2. Run the classifier unless you already know the right lane.
-3. Run the verifier with the cheapest sufficient lane set.
-4. If the classifier emits `flag:real-runtime-candidate`, do not jump straight to runtime verification. First run the non-runtime lanes.
-5. Escalate to explicit `--lane real-runtime --allow-real-runtime` only when cheaper lanes cannot validate the behavior claim.
-6. Return:
-   - verification summary
-   - exact commands run
-   - artifact paths
-   - skipped lanes and blockers
-
-## Quick start
-
-Repo-source quick start:
-
-```bash
-bash .agents/skills/subminer-change-verification/scripts/classify_subminer_diff.sh
-```
-
-Installed-skill quick start:
-
-```bash
-bash "$SUBMINER_VERIFY_SKILL/scripts/classify_subminer_diff.sh"
-```
-
-Classify explicit files:
-
-```bash
-bash .agents/skills/subminer-change-verification/scripts/classify_subminer_diff.sh \
-  launcher/main.ts \
-  plugin/subminer/lifecycle.lua \
-  src/main/runtime/mpv-client-runtime-service.ts
-```
-
-Run automatic lane selection:
-
-```bash
-bash .agents/skills/subminer-change-verification/scripts/verify_subminer_change.sh
-```
-
-Installed-skill form:
-
-```bash
-bash "$SUBMINER_VERIFY_SKILL/scripts/verify_subminer_change.sh"
-```
-
-Run targeted lanes:
-
-```bash
-bash .agents/skills/subminer-change-verification/scripts/verify_subminer_change.sh \
-  --lane launcher-plugin \
-  --lane runtime-compat
-```
-
-Dry-run to inspect planned commands and artifact layout:
-
-```bash
-bash .agents/skills/subminer-change-verification/scripts/verify_subminer_change.sh \
-  --dry-run \
-  launcher/main.ts \
-  src/main.ts
-```
-
-## Lane guidance
-
-- `docs`
-  - For `docs-site/`, `docs/`, and doc-only edits.
-- `config`
-  - For `src/config/` and config-template-sensitive edits.
-- `core`
-  - For general source changes where `typecheck` + `test:fast` is the best cheap signal.
-- `launcher-plugin`
-  - For `launcher/`, `plugin/subminer/`, plugin gating scripts, and wrapper/mpv routing work.
-- `runtime-compat`
-  - For `src/main*`, runtime/composer wiring, mpv/overlay services, window trackers, and dist-sensitive behavior.
-- `real-runtime`
-  - Only after deliberate escalation.
-
-## Real Runtime Escalation
-
-Escalate only when the change claim depends on actual runtime behavior, for example:
-
-- overlay appears, hides, or tracks a real mpv window
-- mpv launch flags or pause-until-ready behavior
-- plugin/socket/auto-start handshake under a real player
-- macOS/window-tracker/focus-sensitive behavior
-
-If the environment cannot support authoritative runtime verification, report the blocker explicitly. Do not silently downgrade a runtime-required claim to a pass.
-
-## Artifact contract
-
-The verifier writes under `.tmp/skill-verification/<timestamp>/`:
-
-- `summary.json`
-- `summary.txt`
-- `classification.txt`
-- `env.txt`
-- `lanes.txt`
-- `steps.tsv`
-- `steps/*.stdout.log`
-- `steps/*.stderr.log`
-
-On failure, quote the exact failing command and point at the artifact directory.
+1. Read the canonical plugin-owned skill.
+2. Follow the plugin-owned skill as the source of truth.
+3. Use the wrapper scripts in this shim directory only for compatibility with existing commands, docs, and backlog history.
+4. Do not duplicate workflow changes here; update the plugin-owned skill and scripts instead.

-description: "Use in the SubMiner repo when a request should be turned into planned work and driven through execution. Assesses whether backlog tracking is warranted, creates or updates tasks when needed, records a plan, dispatches one or more subagents, and requires verification before handoff."
+name: 'subminer-scrum-master'
+description: 'Compatibility shim. Canonical SubMiner scrum-master workflow now lives in the repo-local subminer-workflow plugin.'
 ---
 
-# SubMiner Scrum Master
+# Compatibility Shim
 
-Own workflow, not code by default.
+Canonical source:
 
-Use this skill when the user gives a feature request, bug report, issue, refactor, or implementation ask and the agent should manage intake, planning, backlog hygiene, worker dispatch, and verification through completion.
+- `plugins/subminer-workflow/skills/subminer-scrum-master/SKILL.md`
 
-## Core Rules
+When this shim is invoked:
 
-1. Decide first whether backlog tracking is warranted.
-2. If backlog is needed, search first. Update existing work when it clearly matches.
-3. If backlog is not needed, keep the process light. Do not invent ticket ceremony.
-4. Record a plan before dispatching coding work.
-5. Use parent + subtasks for multi-part work when backlog is used.
-6. Dispatch conservatively. Parallelize only disjoint write scopes.
-7. Require verification before handoff, typically via `subminer-change-verification`.
-8. Report backlog actions, dispatched workers, verification, blockers, and remaining risks.
+1. Read the canonical plugin-owned skill.
+2. Follow the plugin-owned skill as the source of truth.
+3. Do not duplicate workflow changes here; update the plugin-owned skill instead.
 
-## Backlog Decision
-
-Skip backlog when the request is:
-- question only
-- obvious mechanical edit
-- tiny isolated change with no real planning
-
-Use backlog when the work:
-- needs planning or scope decisions
-- spans multiple phases or subsystems
-- is likely to need subagent dispatch
-- should remain traceable for handoff/resume
-
-If backlog is used:
-- search existing tasks first
-- create/update a standalone task for one focused deliverable
-- create/update a parent task plus subtasks for multi-part work
-- record the implementation plan in the task before implementation begins
-
-## Intake Workflow
-
-1. Parse the request.
-   Classify it as question, mechanical edit, bugfix, feature, refactor, investigation, or follow-up.
-2. Decide whether backlog is needed.
-3. If backlog is needed:
-   - search first
-   - update existing task if clearly relevant
-   - otherwise create the right structure
-   - write the implementation plan before dispatch
-4. If backlog is skipped:
-   - write a short working plan in-thread
-   - proceed without fake ticketing
-5. Choose execution mode:
-   - no subagents for trivial work
-   - one worker for focused work
-   - parallel workers only for disjoint scopes
-6. Run verification before handoff.
-
-## Dispatch Rules
-
-The scrum master orchestrates. Workers implement.
-
-- Do not become the default implementer unless delegation is unnecessary.
-- Do not parallelize overlapping files or tightly coupled runtime work.
-- Give every worker explicit ownership of files/modules.
-- Tell every worker other agents may be active and they must not revert unrelated edits.
-- Require each worker to report:
-  - changed files
-  - tests run
-  - blockers
-
-Use worker agents for implementation and explorer agents only for bounded codebase questions.
-
-## Verification
-
-Every nontrivial code task gets verification.
-
-Preferred flow:
-1. use `subminer-change-verification`
-2. start with the cheapest sufficient lane
-3. escalate only when needed
-4. if worker verification is sufficient, accept it or run one final consolidating pass
-
-Never hand off nontrivial work without stating what was verified and what was skipped.
-
-## Pre-Handoff Policy Checks (Required)
-
-Before handoff, always ask and answer both of these questions explicitly:
-
-1. **Docs update required?**
-2. **Changelog fragment required?**
-
-Rules:
-- Do not assume silence implies "no." Record an explicit yes/no decision for each item.
-- If the answer is yes, either complete the update or report the blocker before handoff.
-- Include the final answers in the handoff summary even when both answers are "no."
-
-## Failure / Scope Handling
-
-- If a worker hits ambiguity, pause and ask the user.
-- If verification fails, either:
-  - send the worker back with exact failure context, or
-  - fix it directly if it is tiny and clearly in scope
-- If new scope appears, revisit backlog structure before silently expanding work.
-
-## Representative Flows
-
-### Trivial no-ticket work
-
-- decide backlog is unnecessary
-- keep a short plan
-- implement directly or with one worker if helpful
-- run targeted verification
-- report outcome concisely
-
-### Single-task implementation
-
-- search/create/update one task
-- record plan
-- dispatch one worker
-- integrate
-- verify
-- update task and report outcome
-
-### Parent + subtasks execution
-
-- search/create/update parent task
-- create subtasks for distinct deliverables/phases
-- record sequencing in the plan
-- dispatch workers only where scopes are disjoint
-- integrate
-- run consolidated verification
-- update task state and report outcome
-
-## Output Expectations
-
-At the end, report:
-- whether backlog was used and what changed
-- which workers were dispatched and what they owned
-- what verification ran
-- explicit answers to:
-  - docs update required?
-  - changelog fragment required?
-- blockers, skips, and risks
+This shim exists so existing repo references and prompts keep resolving during the migration to the repo-local plugin workflow.

 # Changelog
 
+## Unreleased
+
+### Fixed
+- AniList: Stopped post-watch tracking from sending a second progress update when the current episode was already satisfied by a ready retry item in the same watch-completion pass.
+
+## v0.10.0 (2026-03-29)
+
+### Changed
+- Integrations: Replaced the deprecated Discord Rich Presence wrapper with the maintained `@xhayper/discord-rpc` package.
+
+### 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.
+
+### 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.

+Addressed the actionable latest CodeRabbit comment on PR #36. `src/core/services/immersion-tracker/maintenance.ts` now skips retention deletions when a window is disabled with `Infinity`, so `toDbMs(...)` is only called for finite retention values. Added a regression test in `maintenance.test.ts` that verifies disabled retention windows preserve session events, telemetry, and sessions while returning zero deletions.

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Follow up the March 2026 codebase-health work with a narrower pass over the biggest remaining production hotspots. The latest review correctly flags `src/main.ts` and `src/types.ts` as maintainability pressure, but it also misses the next real large surfaces that will keep slowing future work: `src/main/character-dictionary-runtime.ts` and `src/core/services/immersion-tracker/query.ts`. This parent task should track focused decomposition work that preserves behavior, avoids redoing already-completed dead-architecture cleanup, and keeps each slice small enough for isolated implementation.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+- [ ] #1 Child tasks exist for each focused cleanup slice instead of one broad “split the monoliths” effort.
+- [ ] #2 The parent task records sequencing so agents do not overlap on `src/main.ts` and other shared surfaces.
+- [ ] #3 The selected follow-up tasks target still-live pressure points, not already-completed work like TASK-87.4, TASK-87.5, or TASK-87.6.
+- [ ] #4 Completion of the child tasks leaves runtime wiring, shared types, character-dictionary orchestration, and immersion-tracker queries materially easier to review and extend.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+Recommended sequencing:
+
+1. Start TASK-238.3 first. A compatibility-first type split reduces churn risk for the later runtime/query refactors.
+2. Run TASK-238.4 and TASK-238.5 in parallel after TASK-238.3 if desired; they touch different domains.
+3. Run TASK-238.1 after or alongside the domain refactors, but keep it focused on window/bootstrap composition only.
+4. Run TASK-238.2 after TASK-238.1 because both touch `src/main.ts` and the CLI/headless flow should build on the cleaner composition root.
+5. Run TASK-238.6 after the current composer/setup-window-factory work lands, so the remaining inline runtime logic and composer gaps are extracted from the already-cleaned composition root.
+6. Run TASK-238.7 only after TASK-238.6 confirms the remaining entrypoint surface still justifies a boot-phase split; then move the boot wiring into dedicated service/runtime/handler modules.
+
+Shared guardrails:
+
+- Do not reopen already-completed dead-module cleanup from TASK-87.5 unless new evidence appears.
+- Keep `src/types.ts` migration compatibility-first; avoid a repo-wide import churn bomb.
+- Prefer extracting named runtime/domain modules over moving code into new giant helper files.
+- Verify each slice with the cheapest sufficient lane, then escalate when a task crosses runtime/build boundaries.

+`src/main.ts` still directly owns several `BrowserWindow` construction and window-lifecycle paths, including overlay-adjacent windows and setup flows. That keeps the composition root far larger than intended and makes window behavior hard to test in isolation. Extract the remaining window/bootstrap composition into named runtime modules so `src/main.ts` mostly wires dependencies and app lifecycle events together.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+- [ ] #1 At least the main overlay window path plus two other window/setup flows are extracted from direct `BrowserWindow` construction inside `src/main.ts`.
+- [ ] #2 The extracted modules expose narrow factory/handler APIs that can be tested without booting the whole app.
+- [ ] #3 `src/main.ts` becomes materially smaller and easier to scan, with window creation concentrated behind well-named runtime surfaces.
+- [ ] #4 Relevant runtime/window tests pass, and new tests are added for any newly isolated window composition helpers.

Migrated the highest-value import surfaces away from `src/types.ts` in config/runtime/Anki-related modules and shared IPC surfaces. Added type-level regression coverage in `src/types-domain-entrypoints.type-test.ts`.

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Users currently have to infer what card output will look like from config fields and post-mine results. Add a live preview surface that shows the resolved card template output before mining so users can catch broken field mappings, missing media, or undesirable formatting earlier.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+- [ ] #1 Users can open a preview that renders the resolved front/back field output for the current note/card template configuration.
+- [ ] #2 The preview clearly surfaces missing or unmapped fields instead of silently showing blank content.
+- [ ] #3 Preview generation uses the same transformation logic as the live card-creation path so it stays trustworthy.
+- [ ] #4 The first slice works with representative sample mining payloads and handles missing optional media gracefully.
+- [ ] #5 Tests cover preview rendering for at least one valid and one invalid/missing-field configuration.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Identify the current card-creation data path and extract any logic needed to render a preview without duplicating transformation rules.
+2. Add a focused preview UI in the most relevant existing configuration/setup surface.
+3. Surface validation/warning states for empty mappings, missing fields, and media-dependent outputs.

+Investigate and fix the visible overlay toggle path on macOS so the user can reliably hide the overlay after it has been shown. The current behavior can ignore the toggle or hide the overlay briefly before it is restored immediately.

+## Acceptance Criteria

+- [x] #1 Pressing the visible-overlay toggle hides the overlay when it is currently shown on macOS.
+- [x] #2 A manual hide is not immediately undone by startup or readiness flows.
+- [x] #3 The mpv/plugin toggle path matches the intended visible-overlay toggle behavior.
+- [x] #4 Regression tests cover the failing toggle path.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Reproduce the toggle/re-show logic from code paths around mpv plugin control commands and auto-play readiness.
+2. Add regression coverage for manual toggle-off staying hidden through readiness completion.
+3. Patch the plugin/control path so manual visible-overlay toggles are not undone by readiness auto-show.
+4. Run targeted tests, then the relevant verification lane.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Root cause: the mpv plugin readiness callback (`subminer-autoplay-ready`) could re-issue `--show-visible-overlay` after a manual toggle/hide. Initial fix only suppressed the next readiness restore, but repeated readiness callbacks in the same media session could still re-show the overlay. The plugin toggle path also still used legacy `--toggle` instead of the explicit visible-overlay command.
+
+Implemented a session-scoped suppression flag in the Lua plugin so a manual hide/toggle during the pause-until-ready window blocks readiness auto-show for the rest of the current auto-start session, then resets on the next auto-start session.
+
+Added Lua regression coverage for both behaviors: manual toggle-off stays hidden through readiness completion, repeated readiness callbacks in the same session stay suppressed, and `subminer-toggle` emits `--toggle-visible-overlay` rather than legacy `--toggle`.
+
+Follow-up investigation found a second issue in `src/core/services/cli-command.ts`: pure visible-overlay toggle commands still ran the MPV connect/start path (`connectMpvClient`) because `--toggle` and `--toggle-visible-overlay` were classified as start-like commands. That side effect could retrigger startup visibility work even after the plugin-side fix.
+
+Updated CLI command handling so only `--start` reconnects MPV. Pure toggle/show/hide overlay commands still initialize overlay runtime when needed, but they no longer restart/reconnect the MPV control path.
+
+Renderer/modal follow-ups: restored focused-overlay mpv y-chord proxy in `src/renderer/handlers/keyboard.ts`, added a modal-close guard in `src/main/overlay-runtime.ts` so modal teardown does not re-show a manually hidden overlay, and added a duplicate-toggle debounce in `src/main/runtime/overlay-visibility-actions.ts` to ignore near-simultaneous toggle requests inside the main process.
+
+2026-03-29: added regression for repeated subminer-autoplay-ready signals after manual y-t hide. Root cause: Lua plugin suppression only blocked the first ready-time restore, so later ready callbacks in the same media session could re-show the visible overlay. Updated plugin suppression to remain active for the full current auto-start session and reset on the next auto-start trigger.
+
+2026-03-29: live mpv log showed repeated `subminer-autoplay-ready` script messages from Electron during paused startup, each triggering plugin `--show-visible-overlay` and immediate re-show. Fixed `src/main/runtime/autoplay-ready-gate.ts` so plugin readiness is signaled once per media while paused retry loops only re-issue `pause=false` instead of re-signaling readiness.
+
+2026-03-29: Added window-level guard for stray visible-overlay re-show on macOS. `src/core/services/overlay-window.ts` now immediately re-hides the visible overlay window on `show` if overlay state is false, covering native/Electron re-show paths that bypass normal visibility actions. Regression: `src/core/services/overlay-window.test.ts`. Verified with full gate and rebuilt unsigned mac bundle.
+
+2026-03-29: added a blur-path guard for the visible overlay window. `src/core/services/overlay-window.ts` now skips topmost restacking when a visible-overlay blur fires after overlay state already flipped off, covering a macOS hide-in-flight path that could immediately reassert the window. Regression coverage added in `src/core/services/overlay-window.test.ts`; verified with targeted overlay tests, full gate, and rebuilt unsigned mac bundle.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Confirmed with user that macOS `y-t` now works. Cleaned the patch set down to the remaining justified fixes: explicit visible-overlay plugin toggle/suppression, pure-toggle CLI no longer reconnects MPV, autoplay-ready signaling only fires once per media, and the final visible-overlay blur guard that stops macOS restacking after a manual hide. Full gate passed again before commit `c939c580` (`fix: stabilize macOS visible overlay toggle`).

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+When the overlay-layout subtitle sidebar is open on macOS, users should still be able to click through outside the sidebar and return keyboard focus to mpv so native mpv keybindings continue to work. The sidebar should stay interactive when hovered or focused, but it must not make the whole visible overlay behave like a blocking modal.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Opening the overlay-layout subtitle sidebar does not keep the entire visible overlay mouse-interactive outside sidebar hover or focus.
+- [x] #2 With the subtitle sidebar open, clicking outside the sidebar can refocus mpv so native mpv keybindings continue to work.
+- [x] #3 Focused regression coverage exists for overlay-layout sidebar passthrough behavior on mouse-ignore state changes.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Add renderer regression coverage for overlay-layout subtitle sidebar passthrough so open-but-unhovered sidebar no longer holds global mouse interaction.
+2. Update overlay mouse-ignore gating to keep the subtitle sidebar interactive only while hovered or otherwise actively interacting, instead of treating overlay layout as a blocking modal.
+3. Run focused renderer tests for subtitle sidebar and mouse-ignore behavior, then update task notes/criteria with the verified outcome.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Confirmed the regression only affects the default overlay-layout subtitle sidebar: open sidebar state was treated as a blocking overlay modal, which prevented click-through outside the sidebar and stranded native mpv keybindings until focus was manually recovered.
+
+Added a failing regression in src/renderer/modals/subtitle-sidebar.test.ts for overlay-layout passthrough before changing the gate.
+
+Verification: bun test src/renderer/modals/subtitle-sidebar.test.ts src/renderer/overlay-mouse-ignore.test.ts; bun run typecheck
+
+User reported the first renderer-only fix did not resolve the macOS issue in practice. Reopening investigation to trace visible-overlay window focus and hit-testing outside the renderer mouse-ignore gate.
+
+Follow-up root cause: sidebar hover handlers were attached to the full-screen `.subtitle-sidebar-modal` shell instead of the actual sidebar panel. On the transparent visible overlay that shell spans the viewport, so sidebar-active state could persist outside the panel and keep the overlay interactive longer than intended.
+
+Updated the sidebar modal to track hover/focus on `subtitleSidebarContent` and derive sidebar interaction state from panel hover or focus-within before recomputing mouse passthrough.
+
+Verification refresh: bun test src/renderer/modals/subtitle-sidebar.test.ts src/renderer/overlay-mouse-ignore.test.ts; bun run typecheck
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Restored overlay subtitle sidebar passthrough in two layers. First, the visible overlay mouse-ignore gate no longer treats the subtitle sidebar as a global blocking modal. Second, the sidebar panel now tracks interaction on the real sidebar content instead of the full-screen modal shell, and keeps itself active only while the panel is hovered or focused. Added regressions for overlay-layout passthrough and focus-within behavior. Verification: `bun test src/renderer/modals/subtitle-sidebar.test.ts src/renderer/overlay-mouse-ignore.test.ts` and `bun run typecheck`.

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+AniList login currently appears to succeed during setup, but some environments cannot persist the token because Electron safeStorage is unavailable or unusable. On the next app start, AniList tracking cannot load the token and re-prompts the user to set up AniList again. Align AniList token persistence with the intended login UX so a token the user already saved is reused on later sessions.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Saved encrypted AniList token is reused on app-ready startup without reopening setup.
+- [x] #2 AniList startup no longer attempts to open the setup BrowserWindow before Electron is ready.
+- [x] #3 AniList auth/runtime tests cover stored-token reuse and the missing-token startup path that previously triggered pre-ready setup attempts.
+- [x] #4 AniList token storage remains encrypted-only; no plaintext fallback is introduced.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Add regression tests for AniList startup auth refresh so a stored encrypted token is reused without opening setup, and for the missing-token path so setup opening is deferred safely until the app can actually show a window.
+2. Update AniList startup/auth runtime to separate token resolution from setup-window prompting, and gate prompting on app readiness instead of attempting BrowserWindow creation during early startup.
+3. Preserve encrypted-only storage semantics in anilist-token-store; do not add plaintext fallback. If stored-token load fails, keep logging/diagnostics intact.
+4. Run targeted AniList runtime/token tests, then summarize root cause and verification results.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Investigated AniList auth persistence flow. Current setup path treats callback token as saved even when anilist-token-store refuses persistence because safeStorage is unavailable. Jellyfin token store already uses plaintext fallback in this environment class, which is a likely model for the AniList fix.
+
+Confirmed from local logs that safeStorage was explicitly unavailable on 2026-03-23 due macOS Keychain lookup failure with NSOSStatusErrorDomain Code=-128 userCanceledErr. Current environment also has an encrypted AniList token file at /Users/sudacode/.config/SubMiner/anilist-token-store.json updated 2026-03-29 18:49, so safeStorage did work recently for save. Repeated AniList setup prompts on 2026-03-29/30 correlate more strongly with startup auth flow deciding no token is available and opening setup immediately; logs show repeated 'Loaded AniList manual token entry page' and several 'Failed to refresh AniList client secret state during startup' errors with 'Cannot create BrowserWindow before app is ready'. No recent log lines indicate safeStorage.isEncryptionAvailable() false after 2026-03-23.
+
+Implemented encrypted-only startup fix by adding an allowSetupPrompt control to AniList token refresh and disabling setup-window prompting for the early pre-ready startup refresh in main.ts. App-ready reloadConfig still performs the normal prompt-capable refresh after Electron is ready. Added regression tests for stored-token reuse and prompt suppression when startup explicitly disables prompting.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Root cause was a redundant early AniList auth refresh during startup. The app refreshed AniList auth once before Electron was ready and again during app-ready config reload. When the early refresh could not resolve a token, it tried to open the AniList setup window immediately, which produced the observed 'Cannot create BrowserWindow before app is ready' failures and repeated setup prompts. The fix keeps token storage encrypted-only, teaches AniList auth refresh to optionally suppress setup-window prompting, and uses that suppression for the early startup refresh. App-ready startup still performs the normal prompt-capable refresh once Electron is ready, so saved encrypted tokens are reused without reopening setup and missing-token setup only happens at a safe point. Verified with targeted AniList auth tests, typecheck, test:fast, test:env, build, and test:smoke:dist.

+2026-03-30: Fixed playlist-browser local playback regression where subtitle track IDs leaked across episode jumps. `playPlaylistBrowserIndexRuntime` now reapplies local subtitle auto-selection defaults (`sub-auto=fuzzy`, `sid=auto`, `secondary-sid=auto`) before `playlist-play-index` for local filesystem targets only; remote playlist entries remain untouched. Added runtime regression tests for both paths.
+
+2026-03-30: Follow-up subtitle regression fix. Pre-jump `sid=auto` was ineffective because mpv resolved it against the current episode before `playlist-play-index`. Local playlist jumps now set `sub-auto=fuzzy`, switch episodes, then schedule a delayed rearm of `sid=auto` and `secondary-sid=auto` so selection happens against the new file's tracks. Added failing-first runtime coverage for delayed local rearm and remote no-op behavior.
+

+2026-03-30 PR #37 unresolved CodeRabbit threads currently reduce to three likely-actionable items plus one outdated renderer dblclick thread to verify against HEAD before touching code.
+
+2026-03-30 Addressed latest unresolved CodeRabbit items on PR #37: preserved playlist-browser selection across mutation snapshots, taught nowMs() to honor string-backed test clocks so it stays aligned with currentDbTimestamp(), and normalized maintenance test timestamp fixtures to toDbTimestamp(). The older playlist-browser dblclick thread remains unresolved in GitHub state but current HEAD already contains that fix in playlist-browser-renderer.ts.
+
+2026-03-30 latest CodeRabbit remediation on PR #37: switched nowMs() numeric test-clock branch from Math.floor() to Math.trunc() so numeric and string-backed mock clocks agree for negative fractional values. Refactored playlist-browser modal tests onto a shared setup/teardown fixture that restores global window/document descriptors correctly, and added regression coverage that injected globals are deleted when originally absent. Verification: `bun test src/core/services/immersion-tracker/time.test.ts src/renderer/modals/playlist-browser.test.ts`, `bun run typecheck`.
+
+2026-03-30 CodeRabbit follow-up: wrapped the injected-globals cleanup regression in try/finally so restore always runs, and changed the keydown test append mock to return createMutationSnapshot() before exercising Ctrl+ArrowDown. Verified with `bun test src/renderer/modals/playlist-browser.test.ts` and `bun run typecheck`.
+
+2026-03-31 assessment: the playlist-browser feature is landed on `main` via `d51e7fe4 Add playlist browser overlay modal (#37)` with runtime, IPC, renderer, keybinding, and changelog/docs coverage present. Verified passes: `bun test src/main/runtime/playlist-browser-runtime.test.ts src/main/runtime/playlist-browser-open.test.ts src/main/runtime/playlist-browser-sort.test.ts src/renderer/handlers/keyboard.test.ts src/core/services/ipc.test.ts src/core/services/ipc-command.test.ts src/config/definitions/domain-registry.test.ts`.
+
+Remaining action item before close: fix `src/renderer/modals/playlist-browser.test.ts` so the cleanup regression does not assume `globalThis.window` / `globalThis.document` start absent under Bun, rerun the playlist-browser modal lane (and then typecheck/build if you want the full closeout proof), then finalize the task.

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Investigate why the bundled texthooker page loads at the local HTTP endpoint but does not reliably connect to the configured websocket feed or receive/display live subtitle lines. Identify the regression in the SubMiner startup/bootstrap or vendored texthooker client path, restore live line delivery, and cover the fix with focused regression tests and any required docs updates.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Bundled texthooker connects to the intended websocket endpoint on launch using the configured/default SubMiner startup path.
+- [x] #2 Incoming subtitle or annotation websocket messages are accepted by the bundled texthooker and rendered as live lines.
+- [x] #3 Regression coverage fails before the fix and passes after the fix for the identified breakage.
+- [x] #4 Relevant docs/config notes are updated if user-facing behavior or troubleshooting guidance changes.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Add a focused CLI regression test covering `--texthooker` startup when the runtime has a resolved websocket URL, proving the handler currently starts texthooker without that URL.
+2. Extend CLI texthooker dependencies/runtime wiring so the handler can retrieve the resolved texthooker websocket URL from current config/runtime state.
+3. Update the CLI texthooker flow to pass the resolved websocket URL into texthooker startup instead of starting the HTTP server with only a port.
+4. Run focused tests for CLI command handling and texthooker bootstrap behavior; update task notes/final summary with the verified root cause and fix.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Root cause: the CLI `--texthooker` path started the HTTP texthooker server with only the port, so the served page never received `bannou-texthooker-websocketUrl` and fell back to the vendored default `ws://localhost:6677`. In environments where the regular websocket was skipped or the annotation websocket should have been used, the page stayed on `Connecting...` and never received lines.
+
+Fix: added a shared `resolveTexthookerWebsocketUrl(...)` helper for websocket selection, reused it in both app-ready startup and CLI texthooker context wiring, and threaded the resolved websocket URL through `handleCliCommand` into `Texthooker.start(...)`.
+
+Verification: `bun run typecheck`; focused Bun tests for texthooker bootstrap, startup, CLI command handling, and CLI context wiring; browser-level repro against a throwaway source-backed texthooker server confirmed the page bootstraps `ws://127.0.0.1:6678`, connects successfully, and renders live sample lines (`テスト一`, `テスト二`).
+
+Docs: no user-facing behavior change beyond restoring the intended existing behavior, so no docs update was required.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Restored texthooker live line delivery for the CLI/startup path that launched the page without a resolved websocket URL. Shared websocket URL resolution between app-ready startup and CLI texthooker context, forwarded that URL into `Texthooker.start(...)`, added regression coverage for the CLI path, and verified both by focused tests and a browser-level throwaway server that connected on `ws://127.0.0.1:6678` and rendered live sample lines.

+Investigate and fix `--texthooker` / `subminer texthooker` startup so it launches the texthooker page without the overlay window but still initializes the runtime pieces required for live subtitle delivery. Today texthooker-only mode serves the page yet skips mpv client and websocket startup, leaving the page pointed at `ws://127.0.0.1:6678` with no listener behind it.

+- [x] #1 `--texthooker` mode starts the texthooker page without opening the overlay window and still initializes the websocket path needed for live subtitle delivery.

+- [x] #4 Docs/help text remain accurate for texthooker-only behavior; update docs only if wording needs correction.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Replace the existing texthooker-only startup regression test so it asserts websocket/mpv startup still happens while overlay window initialization stays skipped.
+2. Remove or narrow the early texthooker-only short-circuit in app-ready startup so runtime config, mpv client, subtitle websocket, and annotation websocket still initialize.
+3. Run focused tests plus a local process check proving `--texthooker` now opens the websocket listener expected by the served page.
+4. Update task notes/final summary with the live-process root cause (`--texthooker` serving HTML on 5174 with no 6678 listener).
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Live-process repro on the user's machine: `ps` showed the active process as `/tmp/.mount_SubMin.../SubMiner --texthooker --port 5174`. `lsof` showed 5174 listening but no listener on 6678/6677, while `curl http://127.0.0.1:5174/` confirmed the served page was correctly bootstrapped to `ws://127.0.0.1:6678`. That proved the remaining failure was startup mode, not page injection.
+
+Root cause: `runAppReadyRuntime(...)` had an early `texthookerOnlyMode` return that reloaded config and handled initial args, but skipped `createMpvClient()`, subtitle websocket startup, annotation websocket startup, subtitle timing tracker creation, and the later texthooker-only branch that only skips the overlay window.
+
+Fix: removed the early texthooker-only short-circuit so texthooker-only mode now runs the normal startup pipeline, then falls through to the existing `Texthooker-only mode enabled; skipping overlay window.` branch.
+
+Verification: `bun run typecheck`; focused Bun tests for app-ready startup, startup bootstrap, CLI texthooker startup, and CLI context wiring. Existing local live-binary repro still reflects the old mounted AppImage until rebuilt/restarted. Current-binary workaround is to launch normal startup / `--start --texthooker` instead of plain `--texthooker`.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Fixed the second texthooker regression: plain `--texthooker` mode was serving the page but skipping mpv/websocket initialization, so the page pointed at `ws://127.0.0.1:6678` with no listener. Removed the early texthooker-only startup return, kept the later overlay-skip behavior, updated the startup regression test to require websocket/mpv initialization in texthooker-only mode, and re-verified with typecheck plus focused test coverage.

+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Design approved by user: normal in-app startup should own texthooker/websocket; `texthookerOnlyMode` should stay explicit external-only.
+
+Root cause path: mpv/plugin auto-start in `plugin/subminer/process.lua` launched `binary_path --start ...` and then separately spawned `binary_path --texthooker --port ...`. That created the standalone helper process observed live (`SubMiner --texthooker --port 5174`) instead of relying on the normal app instance.
+
+Fix: `build_command_args('start', overrides)` now appends `--texthooker` when texthooker is enabled, and the old helper-launch path is reduced to a no-op so normal auto-start remains single-process.
+
+Verification: `lua scripts/test-plugin-start-gate.lua`, `lua scripts/test-plugin-process-start-retries.lua`, `bun test launcher/mpv.test.ts launcher/commands/playback-command.test.ts launcher/config/args-normalizer.test.ts`, and `bun run typecheck`. Standalone launcher/app entrypoints for explicit `subminer texthooker` / plain `--texthooker` were left untouched.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Stopped the mpv/plugin auto-start path from spawning a second standalone texthooker helper. Texthooker now rides on the main `--start` app instance for normal startup, with Lua regressions updated to require `--texthooker` on the main start command and reject separate helper subprocesses. Explicit standalone `subminer texthooker` / plain `--texthooker` entrypoints remain available.

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+On macOS, opening the overlay-layout subtitle sidebar should allow click-through outside the sidebar immediately. Users should not need to first hover subtitle content before passthrough/click-through starts working, including when no subtitle line is currently visible.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 With the overlay-layout subtitle sidebar open on macOS, areas outside the sidebar pass clicks through immediately after open without requiring a prior subtitle hover.
+- [x] #2 When no subtitle line is currently visible, opening the subtitle sidebar still leaves non-sidebar overlay regions click-through on macOS.
+- [x] #3 Regression coverage exercises the first-open/idle passthrough path so overlay interactivity does not depend on a later hover cycle.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Add/adjust focused overlay visibility regressions for the tracked macOS visible overlay so the default idle state stays click-through instead of forcing mouse interaction.
+2. Update main-process visible overlay visibility sync to keep the tracked macOS overlay passive by default and let renderer hover/sidebar state opt into interaction.
+3. Run focused verification for overlay visibility and any dependent runtime tests, then update task notes/criteria/final summary with the confirmed outcome.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Investigation points to a main-process override on macOS: renderer sidebar open path already requests mouse passthrough outside the panel, but visible-overlay visibility sync still hard-sets the tracked overlay window interactive on macOS (`mouse-ignore:false`). Window-tracker focus/visibility resync can therefore undo renderer passthrough until a later hover cycle re-applies it.
+
+Added a failing regression in `src/core/services/overlay-visibility.test.ts` showing the tracked macOS visible overlay was still forced interactive by main-process visibility sync (`mouse-ignore:false`) instead of staying forwarded click-through.
+
+Updated `src/core/services/overlay-visibility.ts` so tracked macOS visible overlays now default to `setIgnoreMouseEvents(true, { forward: true })`, matching the renderer-side passthrough model and preventing window-tracker/focus resync from undoing idle sidebar clickthrough.
+<!-- SECTION:NOTES:END -->

+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Fixed the macOS subtitle-sidebar passthrough regression by changing tracked visible-overlay startup/visibility sync to stay click-through by default in the main process. Previously `updateVisibleOverlayVisibility` forced the macOS overlay window interactive, which could override renderer sidebar passthrough until a later hover cycle repaired it.

+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Thread Yomitan popup/search duplicate note IDs through the existing SubMiner bridge so Kiku/manual grouping can reuse the same duplicate context that already drives the Add duplicate button. Implement and test against the vendored Yomitan copy first; do not rely on upstreamed fork changes yet.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Vendored Yomitan bridge returns duplicate note IDs for popup/search mining when available
+- [x] #2 SubMiner consumes the bridged duplicate IDs and prefers them for Kiku/manual grouping on the Yomitan mining path
+- [x] #3 Regression tests cover the popup/search bridge payload and duplicate-id reuse behavior
+- [x] #4 No commit is made for vendored Yomitan-only changes in this repo state
+<!-- AC:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Vendored files changed locally for validation only: vendor/subminer-yomitan/ext/js/display/display-anki.js, vendor/subminer-yomitan/ext/js/comm/api.js, vendor/subminer-yomitan/ext/js/comm/anki-connect.js, vendor/subminer-yomitan/ext/js/background/backend.js. Do not commit those vendor changes in this repo; port them to the fork instead.

+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Vendored Yomitan popup/search mining now precomputes duplicate note IDs, sends them to the SubMiner Anki proxy as private addNote metadata, and still returns note/duplicate data through the parser bridge. The proxy strips the private metadata before forwarding to upstream AnkiConnect, associates the duplicate IDs with the created note before auto-enrichment begins, and SubMiner also records the bridge result as a secondary cache path. Verified with bun test src/anki-integration/duplicate.test.ts src/anki-integration/card-creation.test.ts src/anki-integration/field-grouping.test.ts src/anki-integration/anki-connect-proxy.test.ts src/core/services/tokenizer/yomitan-parser-runtime.test.ts and bun run typecheck.
