+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+When cycling subtitle tracks with the default J/Shift+J keybindings, the mpv OSD currently shows raw template text like `${sid}` instead of a resolved subtitle label. Update the keybinding OSD behavior so users see the active subtitle selection clearly when cycling tracks, and ensure placeholder-based OSD messages sent through the mpv client API render correctly.
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+<!-- AC:BEGIN -->
+- [x] #1 Pressing the primary subtitle cycle keybinding shows a resolved subtitle label on the OSD instead of a raw `${sid}` placeholder.
+- [x] #2 Pressing the secondary subtitle cycle keybinding shows a resolved subtitle label on the OSD instead of a raw `${secondary-sid}` placeholder.
+- [x] #3 Proxy OSD messages that rely on mpv property expansion render resolved values when sent through the mpv client API.
+- [x] #4 Regression tests cover the subtitle-cycle OSD behavior and the placeholder-expansion OSD path.
+<!-- AC:END -->
+
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+1. Add focused failing tests for subtitle-cycle OSD labels and mpv placeholder-expansion behavior.
+2. Update the IPC mpv command handler to resolve primary and secondary subtitle track labels from mpv `track-list` data after cycling subtitle tracks.
+3. Update the mpv OSD runtime path so placeholder-based `show-text` messages sent through the client API opt into property expansion.
+4. Run focused tests, then the relevant core test lane, and record results in the task notes.
+<!-- SECTION:PLAN:END -->
+
+## Implementation Notes
+
+<!-- SECTION:NOTES:BEGIN -->
+Initial triage: `ipc-command.ts` emits raw `${sid}`/`${secondary-sid}` placeholder strings, and `showMpvOsdRuntime` sends `show-text` via mpv client API without enabling property expansion.
+
+User approved implementation plan on 2026-03-07.
+
+Implementation: proxy mpv command OSD now supports an async resolver so subtitle track cycling can show human-readable labels instead of raw `${sid}` placeholders.
+
+Implementation: `showMpvOsdRuntime` now prefixes placeholder-based messages with mpv client-api `expand-properties`, which fixes raw `${...}` OSD output for subtitle delay/position messages.
+
+Testing: `bun test src/core/services/ipc-command.test.ts src/core/services/mpv-control.test.ts src/main/runtime/mpv-proxy-osd.test.ts src/main/runtime/ipc-mpv-command-main-deps.test.ts src/main/runtime/ipc-bridge-actions.test.ts src/main/runtime/ipc-bridge-actions-main-deps.test.ts src/main/runtime/composers/ipc-runtime-composer.test.ts` passed.
+
+Testing: `bun x tsc --noEmit` passed.
+
+Testing: `bun run test:core:src` passed (423 pass, 6 skip, 0 fail).
+
+Docs: no update required because no checked-in docs or help text describe the J/Shift+J OSD output behavior.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Fixed subtitle-cycle OSD handling for the default J/Shift+J keybindings. The IPC mpv command path now supports resolving proxy OSD text asynchronously, and the main-runtime resolver reads mpv `track-list` state so primary and secondary subtitle cycling show human-readable track labels instead of raw `${sid}` / `${secondary-sid}` placeholders.
+
+Also fixed the lower-level mpv OSD transport so placeholder-based `show-text` messages sent through the client API opt into `expand-properties`. That preserves existing template-based OSD messages like subtitle delay and subtitle position without leaking the raw `${...}` syntax.
+
+Added regression coverage for the async proxy OSD path, the placeholder-expansion `showMpvOsdRuntime` path, and the runtime subtitle-track label resolver. Verification run: `bun x tsc --noEmit`; focused mpv/IPC tests; and the maintained `bun run test:core:src` lane (423 pass, 6 skip, 0 fail).

+
+Validated Claude's five review items. Fixed release workflow ordering/typecheck, removed the duplicate .gitmodules entry, and normalized TASK-101 references to repo-relative paths via Backlog MCP.
+
+Left the vendor/subminer-yomitan branch-pin suggestion unchanged. The committed submodule SHA already controls reproducibility; adding a branch would only affect update ergonomics and was not required to address a concrete defect.
+<!-- SECTION:NOTES:END -->
+
+## Final Summary
+
+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Validated Claude's PR #15 review summary against the current branch and applied the actionable fixes. In `.github/workflows/release.yml`, the release `quality-gate` job now restores the dependency cache before installation, no longer installs twice, and runs `bun run typecheck` before the fast test suite to match CI expectations. In `.gitmodules`, removed the duplicate `vendor/yomitan-jlpt-vocab` stanza with the conflicting duplicate path. Through Backlog MCP, updated `TASK-101` references from an absolute local path to repo-relative paths so the task metadata is portable across contributors.
+
+Verification: `git diff --check`, `git config -f .gitmodules --get-regexp '^submodule\..*\.path$'`, `bun run typecheck`, and `bun run test:fast` all passed. `bun run format:check` still fails on many pre-existing unrelated files already present on the branch, including multiple backlog task files and existing source/docs files; this review patch did not attempt a repo-wide formatting sweep.

+

+
+Updated `make pretty` to call `bun run format:src`. Verified with `make -n pretty` and shell tracing that the helper only targets the maintained allowlist and does not traverse `backlog/` or `vendor/`.
+
+Excluded `Makefile` and `.prettierignore` from the allowlist after verification showed Prettier cannot infer parsers for them.
+<!-- SECTION:NOTES:END -->

+## Final Summary

+<!-- SECTION:FINAL_SUMMARY:BEGIN -->
+Scoped the repo's day-to-day formatting entrypoint without changing the existing broad repo-wide Prettier scripts.

+
+Verification: `make -n pretty` now resolves to `bun run format:src`. `bash -n scripts/prettier-scope.sh` passed, and shell-traced `bash -x scripts/prettier-scope.sh --check` confirmed the exact allowlist passed to Prettier. `bun run format:check:src` fails only because existing files inside the allowed source scope are not currently formatted; it no longer touches `backlog/` or `vendor/`.

+
+Reproduced the failing test locally with `bun test src/renderer/subtitle-render.test.ts`. The failure was a brittle stylesheet assertion, not a renderer behavior regression.
+
+Updated the renderer stylesheet test helper to split selectors safely across `:is(...)` commas and normalize multiline selector whitespace, then switched the failing hover/JLPT assertions to inspect extracted rule blocks instead of matching the entire CSS file text.
+
+Verification passed with `bun test src/renderer/subtitle-render.test.ts` and `bun run test`.

+
+The renderer CSS itself was still correct; the regression was in the test helper. `extractClassBlock` was splitting selector lists on every comma, which breaks selectors containing `:is(...)`, and the affected assertions fell back to brittle whole-file regex matching against a multiline selector. Fixed the test by teaching the helper to split selectors only at top-level commas, normalizing selector whitespace around multiline `:not(...)` / `:is(...)` clauses, and asserting on extracted rule blocks for the plain-word hover and JLPT-only hover/selection rules.
+
+Verification: `bun test src/renderer/subtitle-render.test.ts` passed, and `bun run test` passed end to end (the same fast lane that failed in CI).

-
-**Goal:** Disable subtitle character-name lookup/highlighting when the AniList character dictionary feature is disabled, while keeping tokenization and all other annotations working.
-
-**Architecture:** Gate `getNameMatchEnabled` at the runtime-deps boundary used by subtitle tokenization. Keep the tokenizer pipeline intact and only suppress character-name metadata requests when `anilist.characterDictionary.enabled` is false, regardless of `subtitleStyle.nameMatchEnabled`.

-
-**Architecture:** Keep the existing Bun fast lane intact for routine local verification, but add an explicit SQLite verification lane that runs the database-backed immersion tests under a runtime with `node:sqlite` support. Surface unsupported-runtime behavior clearly in the source tests and contributor docs so skipped or omitted coverage is no longer mistaken for a fully green persistence lane.
-
-**Tech Stack:** TypeScript, Bun scripts in `package.json`, Node's built-in `node:test` and `node:sqlite`, GitHub Actions workflows, Markdown docs in `README.md`.

-### Task 1: Audit and expose the SQLite-backed immersion test surface
-
-**Files:**
-
-- Modify: `src/core/services/immersion-tracker-service.test.ts`
-- Modify: `src/core/services/immersion-tracker/storage-session.test.ts`
-- Reference: `src/main/runtime/registry.test.ts`
-
-**Step 1: Write the failing test**
-
-Refactor the SQLite-gated immersion tests so missing `node:sqlite` support is reported with an explicit skip reason instead of a silent top-level `test.skip` alias.
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test src/core/services/immersion-tracker-service.test.ts src/core/services/immersion-tracker/storage-session.test.ts`
-Expected: the current output shows generic skips or hides the storage-session suite from normal scripted verification, which is too opaque for contributors.
-
-**Step 3: Write minimal implementation**
-
-Mirror the `src/main/runtime/registry.test.ts` pattern: add a helper that either loads `DatabaseSync` or skips with a message like `requires node:sqlite support in this runtime`, then wrap each SQLite-backed test through that helper.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test src/core/services/immersion-tracker-service.test.ts src/core/services/immersion-tracker/storage-session.test.ts`
-Expected: PASS, with explicit skip messages in unsupported runtimes.
-
-### Task 2: Add a reproducible SQLite verification command
-
-**Files:**
-
-- Modify: `package.json`
-- Reference: `src/core/services/immersion-tracker-service.test.ts`
-- Reference: `src/core/services/immersion-tracker/storage-session.test.ts`
-
-**Step 1: Write the failing test**
-
-Add a dedicated script contract for the SQLite-backed immersion verification lane so both persistence-heavy suites are intentionally grouped and runnable together.
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun run test:immersion:sqlite`
-Expected: FAIL because no such reproducible lane exists yet.
-
-**Step 3: Write minimal implementation**
-
-Update `package.json` with explicit scripts for the SQLite lane. Prefer a command shape that actually executes the built JS tests under Node with `node:sqlite` support, for example:
-
-- `test:immersion:sqlite:dist`: `node --test dist/core/services/immersion-tracker-service.test.js dist/core/services/immersion-tracker/storage-session.test.js`
-- `test:immersion:sqlite`: `bun run build && bun run test:immersion:sqlite:dist`
-
-If build cost or runtime behavior requires a small adjustment, keep the core contract the same: one documented command must run both SQLite-backed immersion suites end-to-end.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun run test:immersion:sqlite`
-Expected: PASS in a Node runtime with `node:sqlite`, executing both persistence suites without Bun-only skips.
-
-### Task 3: Wire the SQLite lane into automated verification
-
-**Files:**
-
-- Modify: `.github/workflows/ci.yml`
-- Modify: `.github/workflows/release.yml`
-- Reference: `package.json`
-
-**Step 1: Write the failing test**
-
-Add the new SQLite immersion lane to the repo's automated verification so contributors and CI can rely on a real persistence check rather than the Bun fast lane alone.
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun run test:immersion:sqlite`
-Expected: local command may pass, but CI/release workflows still omit the lane entirely.
-
-**Step 3: Write minimal implementation**
-
-Update both workflows to provision a Node version with `node:sqlite` support before the SQLite lane runs, then execute `bun run test:immersion:sqlite` in the quality gate after the bundle build produces `dist/**` test files.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun run test:immersion:sqlite`
-Expected: PASS locally, and workflow definitions clearly show the SQLite lane as part of automated verification.
-
-### Task 4: Document contributor-facing prerequisites and commands
-
-**Files:**
-
-- Modify: `README.md`
-- Reference: `package.json`
-- Reference: `.github/workflows/ci.yml`
-
-**Step 1: Write the failing test**
-
-Extend the verification docs so contributors can discover the SQLite lane, know why the Bun source lane may skip those cases, and understand which command reproduces the persistence coverage.
-
-**Step 2: Run test to verify it fails**
-
-Run: `grep -n "test:immersion:sqlite" README.md`
-Expected: FAIL because the dedicated immersion SQLite lane is undocumented.
-
-**Step 3: Write minimal implementation**
-
-Update `README.md` to document:
-
-- the Bun fast/default lane versus the SQLite persistence lane
-- the `node:sqlite` prerequisite for the reproducible command
-- that the dedicated lane covers session persistence/finalization behavior beyond seam tests
-
-**Step 4: Run test to verify it passes**
-
-Run: `grep -n "test:immersion:sqlite" README.md && grep -n "node:sqlite" README.md`
-Expected: PASS, with clear contributor guidance.
-
-### Task 5: Verify persistence coverage end-to-end
-
-**Files:**
-
-- Test: `src/core/services/immersion-tracker-service.test.ts`
-- Test: `src/core/services/immersion-tracker/storage-session.test.ts`
-- Reference: `README.md`
-- Reference: `package.json`
-
-**Step 1: Write the failing test**
-
-Prove the final lane exercises real DB-backed persistence/finalization paths, not just the seam tests.
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun run test:immersion:sqlite`
-Expected: before implementation, the command does not exist or does not cover both SQLite-backed suites.
-
-**Step 3: Write minimal implementation**
-
-Keep the dedicated lane pointed at both existing SQLite-backed test files so it covers representative finalization and persistence behavior such as:
-
-- `destroy finalizes active session and persists final telemetry`
-- `start/finalize session updates ended_at and status`
-- `executeQueuedWrite inserts event and telemetry rows`
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun run test:immersion:sqlite`
-Expected: PASS, with those DB-backed persistence/finalization cases executing successfully under Node.

-# Merged Character Dictionary Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Replace per-anime character dictionary imports with one merged Yomitan dictionary driven by MRU usage retention.
-
-**Architecture:** Persist normalized per-media character dictionary snapshots locally, maintain MRU retained media ids in auto-sync state, and rebuild a single merged Yomitan zip only when the retained set changes. Keep external AniList fetches only for media without a local snapshot; normal revisits stay local.

-# Subtitle Sync Verification Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Replace the no-op `test:subtitle` lane with real automated subtitle-sync verification that reuses the maintained subsync tests and documents the real contributor workflow.
-
-**Architecture:** Repoint the subtitle verification command at the existing source-level subsync tests instead of inventing a second hidden suite. Add one focused ffsubsync failure-path test so the subtitle lane explicitly covers both engines plus a non-happy path, then update contributor docs to describe the dedicated subtitle lane and how it relates to `test:core`.
-
-**Tech Stack:** TypeScript, Bun test, Node test/assert, npm package scripts, Markdown docs.
-
----
-
-### Task 1: Lock subtitle lane to real subsync tests
-
-**Files:**
-
-- Modify: `package.json`
-
-**Step 1: Write the failing test**
-
-Define the intended command shape first: `test:subtitle:src` should run `src/core/services/subsync.test.ts` and `src/subsync/utils.test.ts`, `test:subtitle` should invoke that real source lane, and no placeholder echo should remain.
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun run test:subtitle`
-Expected: It performs a build and prints `Subtitle tests are currently not configured`, proving the lane is still a no-op.
-
-**Step 3: Write minimal implementation**
-
-Update `package.json` so:
-
-- `test:subtitle:src` runs `bun test src/core/services/subsync.test.ts src/subsync/utils.test.ts`
-- `test:subtitle` runs the new source lane directly
-- `test:subtitle:dist` is removed if it is no longer the real verification path
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun run test:subtitle`
-Expected: PASS with Bun executing the real subtitle-sync test files.
-
-### Task 2: Add explicit ffsubsync non-happy-path coverage
-
-**Files:**
-
-- Modify: `src/core/services/subsync.test.ts`
-- Test: `src/core/services/subsync.test.ts`
-
-**Step 1: Write the failing test**
-
-Add a test that runs `runSubsyncManual({ engine: 'ffsubsync' })` with a stub ffsubsync executable that exits non-zero and writes stderr, then assert:
-
-- `result.ok === false`
-- `result.message` starts with `ffsubsync synchronization failed`
-- the failure message includes command details surfaced to the user
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun test src/core/services/subsync.test.ts`
-Expected: FAIL because ffsubsync failure propagation is not asserted yet.
-
-**Step 3: Write minimal implementation**
-
-Keep production code unchanged unless the new test exposes a real bug. If needed, tighten failure assertions or message propagation in `src/core/services/subsync.ts` without changing successful behavior.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test src/core/services/subsync.test.ts`
-Expected: PASS with both alass and ffsubsync paths covered, including a non-happy path.
-
-### Task 3: Make contributor docs match the real verification path
-
-**Files:**
-
-- Modify: `README.md`
-- Modify: `package.json`
-
-**Step 1: Write the failing test**
-
-Use the repository state as the failure signal: README currently advertises subtitle sync as a feature but does not tell contributors that `bun run test:subtitle` is the real verification lane.
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun run test:subtitle && bun test src/subsync/utils.test.ts`
-Expected: Tests pass, but docs still do not explain the lane; this is the remaining acceptance-criteria gap.
-
-**Step 3: Write minimal implementation**
-
-Update `README.md` with a short contributor-facing verification note that:
-
-- points to `bun run test:subtitle` for subtitle-sync coverage
-- states that the lane reuses the maintained subsync tests already included in broader core coverage
-- avoids implying there is a separate hidden subtitle test harness beyond those tests
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun run test:subtitle`
-Expected: PASS, with docs and scripts now aligned around the same subtitle verification strategy.
-
-### Task 4: Verify matrix integration stays clean
-
-**Files:**
-
-- Modify: `package.json` (only if Task 1/3 exposed cleanup needs)
-
-**Step 1: Write the failing test**
-
-Treat duplication as the failure condition: confirm the dedicated subtitle lane reuses the same maintained files already present in `test:core:src` rather than creating a second divergent suite.
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun run test:subtitle && bun run test:core:src`
-Expected: If file lists diverge unexpectedly, this review step exposes it before handoff.
-
-**Step 3: Write minimal implementation**
-
-If needed, do the smallest script cleanup necessary so subtitle coverage remains explicit without hiding or duplicating existing core coverage.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun run test:subtitle && bun run test:core:src`
-Expected: PASS, confirming the dedicated lane and the broader core suite agree on subtitle coverage.

-# Testing Workflow Test Matrix Implementation Plan
-
-> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
-
-**Goal:** Make the standard test commands reflect the maintained test surface so newly added tests are discovered automatically or intentionally documented outside the default lane.
-
-**Architecture:** Replace the current hand-maintained file allowlists in `package.json` with directory-based Bun test lanes that map to maintained test surfaces. Keep the default developer lane fast, move slower or environment-specific checks into explicit commands, and document the resulting matrix in `README.md` so contributors know exactly which command to run.
-
-**Tech Stack:** TypeScript, Bun test, npm-style package scripts in `package.json`, Markdown docs in `README.md`.
-
----
-
-### Task 1: Lock in the desired script matrix with failing tests/audit checks
-
-**Files:**
-
-- Modify: `package.json`
-- Test: `package.json`
-- Reference: `src/main-entry-runtime.test.ts`
-- Reference: `src/anki-integration/anki-connect-proxy.test.ts`
-- Reference: `src/main/runtime/registry.test.ts`
-
-**Step 1: Write the failing test**
-
-Add a new script structure in `package.json` expectations by editing the script map so these lanes exist conceptually:
-
-- `test:fast` for default fast verification
-- `test:full` for the maintained source test surface
-- `test:env` for environment-specific checks
-
-The fast lane should stay selective and intentional. The full lane should use directory-based discovery rather than file-by-file allowlists, with representative coverage from:
-
-- `src/main-entry-runtime.test.ts`
-- `src/anki-integration/**/*.test.ts`
-- `src/main/**/*.test.ts`
-- `launcher/**/*.test.ts`
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun run test:full`
-Expected: FAIL because `test:full` does not exist yet, and previously omitted maintained tests are still outside the standard matrix.
-
-**Step 3: Write minimal implementation**
-
-Update `package.json` scripts so:
-
-- `test` points at `test:fast`
-- `test:fast` runs the fast default lane only
-- `test:full` runs directory-based maintained suites instead of file allowlists
-- `test:env` runs environment-specific verification (for example launcher/plugin and sqlite-gated suites)
-- subsystem scripts use stable path globs or directory arguments so new tests are discovered automatically
-
-Prefer commands like these, adjusted only as needed for Bun behavior in this repo:
-
-- `bun test src/config/**/*.test.ts`
-- `bun test src/{cli,core,renderer,subtitle,subsync,main,anki-integration}/*.test.ts ...` only if Bun cannot take the broader directory directly
-- `bun test launcher/**/*.test.ts`
-
-Do not keep large hand-maintained file enumerations for maintained unit/integration lanes.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun run test:full`
-Expected: PASS, including automated execution of representative tests that were previously omitted from the standard matrix.
-
-### Task 2: Separate environment-specific verification from the maintained default/full lanes
-
-**Files:**
-
-- Modify: `package.json`
-- Test: `src/main/runtime/registry.test.ts`
-- Test: `launcher/smoke.e2e.test.ts`
-- Test: `src/core/services/immersion-tracker-service.test.ts`
-
-**Step 1: Write the failing test**
-
-Refine the package scripts so environment-specific checks are explicitly grouped outside the default fast lane. Treat these as the primary environment-specific examples unless repo behavior proves a better split during execution:
-
-- launcher smoke/plugin checks that rely on local process or Lua execution
-- sqlite-dependent checks that may skip when `node:sqlite` is unavailable
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun run test:env`
-Expected: FAIL because the environment-specific lane is not defined yet.
-
-**Step 3: Write minimal implementation**
-
-Add explicit environment-specific scripts in `package.json`, such as:
-
-- a launcher/plugin lane that runs `launcher/smoke.e2e.test.ts` plus `lua scripts/test-plugin-start-gate.lua`
-- a sqlite lane for tests that require `node:sqlite` support or otherwise need environment notes
-- an aggregate `test:env` command that runs all environment-specific lanes
-
-Keep these lanes documented and reproducible rather than silently excluded.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun run test:env`
-Expected: PASS in supported environments, or clear documented skip behavior where the tests themselves intentionally gate on missing runtime support.
-
-### Task 3: Document contributor-facing test commands and matrix
-
-**Files:**
-
-- Modify: `README.md`
-- Reference: `package.json`
-
-**Step 1: Write the failing test**
-
-Add a contributor-focused testing section requirement in `README.md` expectations:
-
-- fast verification command
-- full verification command
-- environment-specific verification command
-- plain-language explanation of which suites each lane covers and why
-
-**Step 2: Run test to verify it fails**
-
-Run: `grep -n "Testing" README.md`
-Expected: no contributor testing matrix section exists yet.
-
-**Step 3: Write minimal implementation**
-
-Update `README.md` with a concise `Testing` section that documents:
-
-- `bun run test` / `bun run test:fast` for fast local verification
-- `bun run test:full` for the maintained source test surface
-- `bun run test:env` for environment-specific verification
-- any important notes about sqlite-gated tests and launcher/plugin checks
-
-Keep the matrix concrete and reproducible.
-
-**Step 4: Run test to verify it passes**
-
-Run: `grep -n "Testing" README.md && grep -n "test:full" README.md && grep -n "test:env" README.md`
-Expected: PASS with the new contributor-facing matrix present.
-
-### Task 4: Verify representative omitted suites now belong to automated lanes
-
-**Files:**
-
-- Test: `src/main-entry-runtime.test.ts`
-- Test: `src/anki-integration/anki-connect-proxy.test.ts`
-- Test: `src/main/runtime/registry.test.ts`
-- Reference: `package.json`
-- Reference: `README.md`
-
-**Step 1: Write the failing test**
-
-Use targeted command checks to prove these previously omitted surfaces are now in the matrix:
-
-- entry/runtime: `src/main-entry-runtime.test.ts`
-- Anki integration: `src/anki-integration/anki-connect-proxy.test.ts`
-- main runtime: `src/main/runtime/registry.test.ts`
-
-**Step 2: Run test to verify it fails**
-
-Run: `bun run test:full src/main-entry-runtime.test.ts`
-Expected: either unsupported invocation or evidence that the current matrix still does not include these surfaces automatically.
-
-**Step 3: Write minimal implementation**
-
-Adjust the final script paths/globs until the full matrix includes those representative surfaces without file-by-file script maintenance.
-
-**Step 4: Run test to verify it passes**
-
-Run: `bun test src/main-entry-runtime.test.ts src/anki-integration/anki-connect-proxy.test.ts src/main/runtime/registry.test.ts && bun run test:fast && bun run test:full`
-Expected: PASS, with at least one representative test from each required surface executing through the documented automated lanes.
