+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Current commit history and repo state are analyzed
+- [x] #2 Recommended history-cleanup strategy is justified
+- [x] #3 initial-release.md contains exact copy/paste commands with safety checks and team cutover steps

+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Analyzed `main` history and repository state, then recommended an orphan-branch history rewrite with curated commits as the safest pre-release cleanup path. Added `initial-release.md` with exact copy/paste commands for backups, optional stash handling, orphan branch creation, 7-commit split staging strategy, tree-equivalence validation, force-with-lease cutover, tagging, and collaborator resync instructions.

+
+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Recent `plugin/subminer.lua` change added an IPC readiness gate in `start_overlay()` that rejects start when no SubMiner process exists yet. This blocks manual start (`y-s`) and script-message start even when binary path overrides are valid (`SUBMINER_APPIMAGE_PATH`, `SUBMINER_BINARY_PATH`, `binary_path`).
+
+Need to restore expected behavior:
+- allow cold start when process is not running,
+- preserve mismatch/misconfiguration checks when process is already running,
+- add regression coverage for the new start gate behavior.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Action Steps
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Add failing regression test covering cold-start path from plugin start gate.
+2. Patch `start_overlay()` gate logic so process-not-running does not block initial start.
+3. Keep existing IPC mismatch/missing-socket checks for running-process path.
+4. Re-run plugin validation and focused tests.
+<!-- SECTION:PLAN:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 `y-s` / `subminer-start` can launch overlay when SubMiner is not yet running and binary is available.
+- [x] #2 Plugin still surfaces clear refusal for true IPC/socket mismatches after process is running.
+- [x] #3 Regression test exists and fails before fix / passes after fix.
+<!-- AC:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+- Patched `plugin/subminer.lua` start gate: `start_overlay()` now treats `SubMiner process not running` as a valid cold-start condition and only refuses start for other IPC readiness failures.
+- Added regression harness `scripts/test-plugin-start-gate.lua` to load plugin with mocked mpv APIs and assert `subminer-start` triggers `--start` command for cold-start path.
+- Validation:
+  - red: `SUBMINER_APPIMAGE_PATH=/tmp/subminer-binary lua scripts/test-plugin-start-gate.lua` (failed before patch with expected cold-start assertion),
+  - green: same command passes after patch,
+  - `luac -p plugin/subminer.lua`,
+  - `bun test launcher/mpv.test.ts`.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Fixed mpv plugin start regression by allowing cold-start launch when SubMiner process is not yet running, while preserving existing refusal path for non-cold-start IPC readiness errors. Added an executable Lua regression harness for this path and validated with syntax + focused launcher MPV tests.

+The main process has three layers: `main.ts` delegates to composition modules that wire together domain services. Three overlay windows (visible, invisible, secondary) run in separate Electron renderer processes, connected through `preload.ts`. External runtimes (launcher CLI and mpv plugin) operate independently and communicate via IPC socket or CLI passthrough.

 ## Program Lifecycle
 
-- **Startup:** `startup.ts` parses CLI args and detects the compositor backend. If `--generate-config` is passed, it writes the template and exits. Otherwise `app-lifecycle.ts` acquires the single-instance lock and registers Electron lifecycle hooks.
+- **Module-level init:** Before `app.ready`, the composition root registers protocols, sets platform flags, constructs all services, and wires dependency injection. `runAndApplyStartupState()` parses CLI args and detects the compositor backend.
-- **Initialization:** Once `app.whenReady()` fires, `composeAppReadyRuntime()` runs the critical path first (strict config reload, runtime options + keybindings, mpv client creation, overlay/IPC setup). Non-critical warmups are launched asynchronously (`mecab`, `yomitan-extension`, dictionary prewarm, optional Jellyfin remote session).
+- **Startup:** If `--generate-config` is passed, it writes the template and exits. Otherwise `app-lifecycle.ts` acquires the single-instance lock and registers Electron lifecycle hooks.
-- **Runtime:** Event-driven. mpv events, IPC messages, CLI commands, overlay shortcuts, hot-reload notifications, and integration callbacks route through runtime handlers/composers, update `AppState`, and broadcast to overlay windows.
+- **Critical-path init:** Once `app.whenReady()` fires, `composeAppReadyRuntime()` runs strict config reload, resolves keybindings, creates the `MpvIpcClient` (which immediately connects and subscribes to 26 properties), and initializes the `RuntimeOptionsManager`, `SubtitleTimingTracker`, and `ImmersionTrackerService`.
-- **Overlay window model:** runtime manages three overlay windows: `visible`, `invisible`, and `secondary`. `splitOverlayGeometryForSecondaryBar()` reserves the top 20% for the secondary subtitle bar and routes the remaining area to the active primary overlay layer.
+- **Overlay runtime:** `initializeOverlayRuntime()` creates three overlay windows — **visible** (interactive Yomitan lookups), **invisible** (mpv-matched subtitle positioning), and **secondary** (secondary subtitle bar, top 20% via `splitOverlayGeometryForSecondaryBar`) — then registers global shortcuts and sets initial bounds from the window tracker.
-- **Shutdown:** `onWillQuitCleanup` tears down tray + watchers + integrations, stops subtitle/texthooker servers, flushes buffered MPV OSD log writes, closes token/session windows, and stops Jellyfin/Discord runtime services.
+- **Background warmups:** Non-critical services are launched asynchronously: MeCab tokenizer check, Yomitan extension load, JLPT + frequency dictionary prewarm, optional Jellyfin remote session, Discord presence service, and AniList token refresh.
+- **Runtime:** Event-driven. mpv property changes, IPC messages, CLI commands, overlay shortcuts, and hot-reload notifications route through runtime handlers/composers. Subtitle text flows through `SubtitlePipeline` (normalize → tokenize → merge), and results broadcast to all overlay windows.
+- **Shutdown:** `onWillQuitCleanup` destroys tray + config watcher, unregisters shortcuts, stops WebSocket + texthooker servers, closes the mpv socket + flushes OSD log, stops the window tracker, closes the Yomitan parser window, flushes the immersion tracker (SQLite), stops Jellyfin/Discord services, and cleans Anki/AniList state.

+# Initial Release Git History Cleanup Plan
+
+## Recommendation
+
+Given the current `main` history shape (325 commits, heavy refactor churn, and many internal maintenance commits), the best pre-release cleanup path is:
+
+1. Preserve the old `main` history in remote backup refs.
+2. Build a **new orphan history** from the current project snapshot.
+3. Recreate history as **7 curated commits** grouped by release-facing domains.
+4. Verify tree equality with old `main` and replace `origin/main` once.
+
+This avoids fragile `rebase -i --root` over 300+ commits while still keeping meaningful archaeology for future maintenance.
+
+## Why this is best for this repo
+
+- Current history is dominated by refactor/noise commits (`refactor`: 138, `other`: 91).
+- Commit velocity is very high and bursty (multiple 30-45 commit days), so interactive cleanup is risky/time-expensive.
+- Codebase is already mature and release-shaped (Electron app + launcher + plugin + docs + CI), so snapshot regrouping is cleaner.
+- You are pre-release and private; a one-time force update is low risk if coordinated.
+
+---
+
+## Pre-cutover checklist
+
+Run from repository root.
+
+```bash
+git checkout main
+git pull --ff-only origin main
+```
+
+Coordinate freeze:
+
+- Pause merges/pushes to `main`.
+- Ask teammates to stop rebasing onto `main` during cutover.
+
+---
+
+## Copy/paste command sequence
+
+### 1) Safety backups (local + remote)
+
+```bash
+set -euo pipefail
+
+git checkout main
+git pull --ff-only origin main
+
+OLD_MAIN_COMMIT="$(git rev-parse main)"
+STAMP="$(date -u +%Y%m%dT%H%M%SZ)"
+
+echo "Old main commit: ${OLD_MAIN_COMMIT}"
+echo "Cutover stamp: ${STAMP}"
+
+git tag "pre-release-history-backup-${STAMP}" "${OLD_MAIN_COMMIT}"
+git branch "archive/pre-release-history-${STAMP}" "${OLD_MAIN_COMMIT}"
+
+git push origin "pre-release-history-backup-${STAMP}"
+git push origin "archive/pre-release-history-${STAMP}"
+```
+
+### 2) Handle dirty workspace safely
+
+If `git status --short` is not empty:
+
+```bash
+git stash push -u -m "initial-release-history-cleanup-${STAMP}"
+```
+
+### 3) Build new clean history on orphan branch
+
+```bash
+git checkout --orphan release/main-clean
+git reset
+```
+
+Now create curated commits.
+
+```bash
+# Commit 1: repository scaffolding and build toolchain
+git add .gitignore .gitmodules .npmrc .prettierignore .prettierrc.json AGENTS.md LICENSE Makefile package.json bun.lock tsconfig.json tsconfig.renderer.json build scripts .github
+git commit -m "chore: bootstrap repository tooling and release automation"
+
+# Commit 2: core desktop app runtime
+git add src
+git commit -m "feat(core): add Electron runtime, services, and app composition"
+
+# Commit 3: launcher and mpv plugin integration
+git add launcher plugin subminer
+git commit -m "feat(integration): add launcher and mpv plugin workflows"
+
+# Commit 4: bundled assets and vendor payloads
+git add assets vendor
+git commit -m "feat(assets): bundle runtime assets and vendor dependencies"
+
+# Commit 5: test suites and verification harnesses
+git add tests
+git commit -m "test: add regression suites and harness coverage"
+
+# Commit 6: documentation and examples
+git add README.md docs config.example.jsonc
+git commit -m "docs: add setup guides, architecture docs, and config examples"
+
+# Commit 7: project/backlog metadata and remaining files (if any)
+git add -A
+if ! git diff --cached --quiet; then
+  git commit -m "chore: add project management metadata and remaining repository files"
+fi
+```
+
+### 4) Validate tree equivalence to old main snapshot
+
+```bash
+git diff --stat "${OLD_MAIN_COMMIT}^{tree}" HEAD^{tree}
+git diff --name-status "${OLD_MAIN_COMMIT}^{tree}" HEAD^{tree}
+```
+
+Expected: no output. If output exists, stop and inspect before pushing.
+
+### 5) Replace `origin/main`
+
+```bash
+git push --force-with-lease origin release/main-clean:main
+```
+
+### 6) Tag cleaned initial-release baseline
+
+```bash
+git fetch origin
+git checkout main
+git reset --hard origin/main
+git tag "v0.1.0-initial-clean-history"
+git push origin "v0.1.0-initial-clean-history"
+```
+
+### 7) Restore local stashed work (if stashed earlier)
+
+```bash
+git stash list
+git stash pop
+```
+
+---
+
+## Team resync message (send after cutover)
+
+```text
+main history was rewritten for initial release cleanup.
+
+If you have no local work:
+  git fetch origin
+  git checkout main
+  git reset --hard origin/main
+
+If you have local work:
+  git fetch origin
+  git checkout -b backup/<name>-before-main-rewrite
+  # then rebase/cherry-pick your feature commits onto new origin/main
+```
+
+---
+
+## Notes
+
+- This plan intentionally avoids `git rebase -i --root` to reduce conflict risk.
+- `--force-with-lease` is mandatory safety rail.
+- Keep the backup tag/branch until after public release stabilization.
