Refactor startup, queries, and workflow into focused modules (#36)

* chore(backlog): add mining workflow milestone and tasks

* refactor: split character dictionary runtime modules

* refactor: split shared type entrypoints

* refactor: use bun serve for stats server

* feat: add repo-local subminer workflow plugin

* fix: add stats server node fallback

* refactor: split immersion tracker query modules

* chore: update backlog task records

* refactor: migrate shared type imports

* refactor: compose startup and setup window wiring

* Add backlog tasks and launcher time helper tests

- Track follow-up cleanup work in Backlog.md
- Replace Date.now usage with shared nowMs helper
- Add launcher args/parser and core regression tests

* test: increase launcher test timeout for CI stability

* fix: address CodeRabbit review feedback

* refactor(main): extract remaining inline runtime logic from main

* chore(backlog): update task notes and changelog fragment

* refactor: split main boot phases

* test: stabilize bun coverage reporting

* Switch plausible endpoint and harden coverage lane parsing

- update docs-site tracking to use the Plausible capture endpoint
- tighten coverage lane argument and LCOV parsing checks
- make script entrypoint use CommonJS main guard

* Restrict docs analytics and build coverage input

- limit Plausible init to docs.subminer.moe
- build Yomitan before src coverage lane

* fix(ci): normalize Windows shortcut paths for cross-platform tests

* Fix verification and immersion-tracker grouping

- isolate verifier artifacts and lease handling
- switch weekly/monthly tracker cutoffs to calendar boundaries
- tighten boot lifecycle and zip writer tests

* fix: resolve CI type failures in boot and immersion query tests

* fix: remove strict spread usage in Date mocks

* fix: use explicit super args for MockDate constructors

* Factor out mock date helper in tracker tests

- reuse a shared `withMockDate` helper for date-sensitive query tests
- make monthly rollup assertions key off `videoId` instead of row order

* fix: use variadic array type for MockDate constructor args

TS2367: fixed-length tuple made args.length === 0 unreachable.

* refactor: remove unused createMainBootRuntimes/Handlers aggregate functions

These functions were never called by production code — main.ts imports
the individual composeBoot* re-exports directly.

* refactor: remove boot re-export alias layer

main.ts now imports directly from the runtime/composers and runtime/domains
modules, eliminating the intermediate boot/ indirection.

* refactor: consolidate 3 near-identical setup window factories

Extract shared createSetupWindowHandler with a config parameter.
Public API unchanged.

* refactor: parameterize duplicated getAffected*Ids query helpers

Four structurally identical functions collapsed into two parameterized
helpers while preserving the existing public API.

* refactor: inline identity composers (stats-startup, overlay-window)

composeStatsStartupRuntime was a no-op that returned its input.
composeOverlayWindowHandlers was a 1-line delegation.
Both removed in favor of direct usage.

* chore: remove unused token/queue file path constants from main.ts

* fix: replace any types in boot services with proper signatures

* refactor: deduplicate ensureDir into shared/fs-utils

5 copies of mkdir-p-if-not-exists consolidated into one shared module
with ensureDir (directory path) and ensureDirForFile (file path) variants.

* fix: tighten type safety in boot services

- Add AppLifecycleShape and OverlayModalInputStateShape constraints
  so TAppLifecycleApp and TOverlayModalInputState generics are bounded
- Remove unsafe `as { handleModalInputStateChange? }` cast — now
  directly callable via the constraint
- Use `satisfies AppLifecycleShape` for structural validation on the
  appLifecycleApp object literal
- Document Electron App.on incompatibility with simple signatures

* refactor: inline subtitle-prefetch-runtime-composer

The composer was a pure pass-through that destructured an object and
reassembled it with the same fields. Inlined at the call site.

* chore: consolidate duplicate import paths in main.ts

* test: extract mpv composer test fixture factory to reduce duplication

* test: add behavioral assertions to composer tests

Upgrade 8 composer test files from shape-only typeof checks to behavioral
assertions that invoke returned handlers and verify injected dependencies are
actually called, following the mpv-runtime-composer pattern.

* refactor: normalize import extensions in query modules

* refactor: consolidate toDbMs into query-shared.ts

* refactor: remove Node.js fallback from stats-server, use Bun only

* Fix monthly rollup test expectations

- Preserve multi-arg Date construction in mock helper
- Align rollup assertions with the correct videoId

* fix: address PR 36 CodeRabbit follow-ups

* fix: harden coverage lane cleanup

* fix(stats): fallback to node server when Bun.serve unavailable

* fix(ci): restore coverage lane compatibility

* chore(backlog): close TASK-242

* fix: address latest CodeRabbit review round

* fix: guard disabled immersion retention windows

* fix: migrate discord rpc wrapper

* fix(ci): add changelog fragment for PR 36

* fix: stabilize macOS visible overlay toggle

* fix: pin installed mpv plugin to current binary

* fix: strip inline subtitle markup from sidebar cues

* fix(renderer): restore subtitle sidebar mpv passthrough

* feat(discord): add configurable presence style presets

Replace the hardcoded "Mining and crafting (Anki cards)" meme message
with a preset system. New `discordPresence.presenceStyle` option
supports four presets: "default" (clean bilingual), "meme" (the OG
Minecraft joke), "japanese" (fully JP), and "minimal". The default
preset shows "Sentence Mining" with 日本語学習中 as the small image
tooltip. Existing users can set presenceStyle to "meme" to keep the
old behavior.

* fix: finalize v0.10.0 release prep

* docs: add subtitle sidebar guide and release note

* chore(backlog): mark docs task done

* fix: lazily resolve youtube playback socket path

* chore(release): build v0.10.0 changelog

* Revert "chore(release): build v0.10.0 changelog"

This reverts commit 9741c0f020.

-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."
+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`
+Canonical helper scripts:
-  - 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.
 
-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
+When this shim is invoked:
-export SUBMINER_VERIFY_SKILL="<path-to-skill>"
-```
 
-## Default workflow
+1. Read the canonical plugin-owned skill.
-
+2. Follow the plugin-owned skill as the source of truth.
-1. Inspect the changed files or user-requested area.
+3. Use the wrapper scripts in this shim directory only for compatibility with existing commands, docs, and backlog history.
-2. Run the classifier unless you already know the right lane.
+4. Do not duplicate workflow changes here; update the plugin-owned skill and scripts instead.
-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.

-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."
+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.
+1. Read the canonical plugin-owned skill.
-2. If backlog is needed, search first. Update existing work when it clearly matches.
+2. Follow the plugin-owned skill as the source of truth.
-3. If backlog is not needed, keep the process light. Do not invent ticket ceremony.
+3. Do not duplicate workflow changes here; update the plugin-owned skill instead.
-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.
 
-## Backlog Decision
+This shim exists so existing repo references and prompts keep resolving during the migration to the repo-local plugin workflow.
-
-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

 # Changelog
 
+## 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.
+
+## v0.9.3 (2026-03-25)
+
+### 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.
+
 ## v0.9.2 (2026-03-25)

+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Addressed the confirmed latest CodeRabbit review items on PR #36. `scripts/run-coverage-lane.ts` now uses the Bun-style `import.meta.main` entrypoint check with a local ts-ignore to preserve the repo's CommonJS typecheck settings. `src/core/services/immersion-tracker/maintenance.ts` no longer shadows the imported `nowMs` helper in retention functions. `src/main.ts` now centralizes the startup-mode predicates behind a shared helper and releases `resolvedSource.cleanup` on the cached-subtitle fast path so materialized sources do not leak.

+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+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.
