+name: "subminer-change-verification"
+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."
+---
+
+# SubMiner Change Verification
+
+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.
+
+## Scripts
+
+- `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.
+
+If you need an explicit installed path, use the directory that contains this `SKILL.md`. The helper scripts live under:
+
+```bash
+export SUBMINER_VERIFY_SKILL="<path-to-skill>"
+```
+
+## 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.

+name: "subminer-scrum-master"
+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."
+---
+
+# SubMiner Scrum Master
+
+Own workflow, not code by default.
+
+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.
+
+## Core Rules
+
+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.
+
+## 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

 # Changelog
 
+## v0.6.2 (2026-03-12)
+
+### Changed
+- Config: Added `yomitan.externalProfilePath` to reuse another Electron app's Yomitan profile in read-only mode.
+- Config: SubMiner now reuses external Yomitan dictionaries/settings without writing back to that profile.
+- Config: Launcher-managed playback now respects `yomitan.externalProfilePath` and no longer forces first-run setup when external Yomitan is configured.
+- Config: SubMiner now seeds `config.jsonc` even when the default config directory already exists.
+- Config: First-run setup now allows zero internal dictionaries when `yomitan.externalProfilePath` is configured, and falls back to requiring at least one internal dictionary if that external profile is later removed.
+
+## v0.6.1 (2026-03-12)
+
+### Added
+- Overlay: Added Chrome Gamepad API controller support for keyboard-only overlay mode, including configurable logical bindings for lookup, mining, popup navigation, Yomitan audio, mpv pause, d-pad fallback navigation, and slower smooth popup scrolling.
+- Overlay: Added `Alt+C` controller selection and `Alt+Shift+C` controller debug modals, with preferred controller persistence and live raw input inspection.
+- Overlay: Added a transient in-overlay controller-detected indicator when a controller is first found.
+- Overlay: Fixed stale keyboard-only token highlight cleanup when keyboard-only mode turns off or the Yomitan popup closes.
+
+### Docs
+- Install: Added Arch Linux AUR install docs for `subminer-bin` in the README and installation guide.
+
+### Internal
+- Config: add an enforced `verify:config-example` gate so checked-in example config artifacts cannot drift silently
+- Release: Fixed the release workflow token permissions so tagged builds can download `oven-sh/setup-bun` and publish artifacts again.
+
 ## v0.5.6 (2026-03-10)

+
+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+
+Add Chrome Gamepad API support to the visible overlay as a supplement to keyboard-only mode. By default SubMiner should bind to the first available controller, allow the user to pick and persist a preferred controller, expose a raw-input debug modal, and map controller actions onto the existing keyboard-only/Yomitan flow without breaking keyboard input. Also fix the current keyboard-only cleanup bug so the selected-token highlight clears when keyboard-only mode turns off or when the Yomitan popup closes.
+
+<!-- SECTION:DESCRIPTION:END -->
+
+## Acceptance Criteria
+
+<!-- AC:BEGIN -->
+
+- [x] #1 Controller input is ignored unless keyboard-only mode is enabled, except the controller binding for toggling keyboard-only mode itself.
+- [x] #2 Default logical mappings work: smooth popup scroll, token selection, lookup toggle/close, mining, Yomitan audio navigation/play, and mpv play/pause.
+- [x] #3 Controller config supports named logical bindings plus tuning knobs (preferred controller, deadzones, smooth-scroll speed/repeat), not raw axis/button maps.
+- [x] #4 `Alt+C` opens a controller selection modal listing connected controllers; saving a choice persists the preferred controller for next launch.
+- [x] #5 `Alt+Shift+C` opens a debug modal showing live raw controller axes/buttons as seen by SubMiner.
+- [x] #6 Keyboard-only selection highlight clears immediately when keyboard-only mode is disabled or the Yomitan popup closes.
+- [x] #7 Renderer/config regression tests cover controller gating, mappings, modal behavior, persisted selection, and highlight cleanup.
+- [x] #8 Docs/config example describe the controller feature and new shortcuts.
+
+<!-- AC:END -->
+
+## Implementation Notes
+
+- Added renderer-side gamepad polling and logical action mapping in `src/renderer/handlers/gamepad-controller.ts`.
+- Added controller select/debug modals, persisted preferred-controller IPC, and top-level `controller` config defaults/schema/template output.
+- Added a transient in-overlay controller status indicator when a controller is first detected.
+- Tuned controller defaults and routing after live testing: d-pad fallback navigation, slower repeat timing, DOM-backed popup-open detection, and direct pixel scroll/audio-source popup bridge commands.
+- Reused existing keyboard-only lookup/mining/navigation flows so controller input stays a supplement to keyboard-only mode instead of a parallel input path.
+- Verified keyboard-only highlight cleanup on mode-off and popup-close paths with renderer tests.

 # Changelog
 
+## v0.6.2 (2026-03-12)
+- Added `yomitan.externalProfilePath` so SubMiner can reuse another Electron app's Yomitan profile in read-only mode.
+- Reused external Yomitan dictionaries/settings without writing back to that profile.
+- Let launcher-managed playback honor external Yomitan config instead of forcing first-run setup.
+- Seeded `config.jsonc` even when the default config directory already exists.
+- Let first-run setup complete without internal dictionaries while external Yomitan is configured, then require an internal dictionary again only if that external profile is later removed.
+
+## v0.6.0 (2026-03-12)
+- Added Chrome Gamepad API controller support for keyboard-only overlay mode.
+- Added configurable controller bindings for lookup, mining, popup navigation, Yomitan audio, mpv pause, and d-pad fallback navigation.
+- Added smooth, slower popup scrolling for controller navigation.
+- Added `Alt+C` controller selection and `Alt+Shift+C` controller debug modals, with preferred controller persistence and live raw input inspection.
+- Added a transient in-overlay controller-detected indicator when a controller is first found.
+- Fixed cleanup of stale keyboard-only token highlights when keyboard-only mode is disabled or when the Yomitan popup closes.
+- Added an enforced `verify:config-example` gate so checked-in example config artifacts cannot drift silently.
+
 ## v0.5.6 (2026-03-10)
 - Persisted merged character-dictionary MRU state as soon as a new retained set is built so revisits do not get dropped if later Yomitan import work fails.
 - Fixed early Electron startup writing config and user data under a lowercase `~/.config/subminer` path instead of canonical `~/.config/SubMiner`.

+### Controller Support
+
+SubMiner can read controllers through the Chrome Gamepad API and map them onto the existing keyboard-only overlay workflow.
+
+Important behavior:
+
+- Controller input is only active while keyboard-only mode is enabled.
+- Keyboard-only mode continues to work normally without a controller.
+- By default SubMiner uses the first connected controller.
+- `Alt+C` opens the controller selection modal and saves the selected controller for future launches.
+- `Alt+Shift+C` opens a live debug modal showing raw axes/button values plus a ready-to-copy `buttonIndices` config block.
+- Turning keyboard-only mode off clears the keyboard-only token highlight state.
+- Closing the Yomitan popup clears the temporary native text-selection fill, but keeps controller token selection active.

+- SubMiner reads the external profile's currently active Yomitan profile selection and installed dictionaries.
+- SubMiner does not open its own Yomitan settings window in this mode.
+- SubMiner does not import, delete, or update dictionaries/settings in the external profile.
+- SubMiner character-dictionary features are fully disabled in this mode, including auto-sync, manual generation, and subtitle-side character-dictionary annotations.
+- First-run setup does not require any internal dictionaries while this mode is configured. If you later launch without `yomitan.externalProfilePath`, setup will require at least one internal Yomitan dictionary unless SubMiner already finds one.

+5. **Mine** — press `X` to create an Anki card for the current sentence (same as `Ctrl+S`).
+6. **Close** — press `B` to dismiss the Yomitan popup and return to subtitle navigation.

+## Controller Support
+
+SubMiner supports gamepad/controller input for couch-friendly usage via the Chrome Gamepad API. Controller input drives the overlay while keyboard-only mode is enabled.
+
+### Getting Started
+
+1. Connect a controller before or after launching SubMiner.
+2. Enable keyboard-only mode — press `Y` on the controller (default binding) or use the overlay keybinding.
+3. Use the left stick to navigate subtitle tokens and the right stick to scroll the Yomitan popup.
+4. Press `A` to look up the selected word, `X` to mine a card, `B` to close the popup.
+
+By default SubMiner uses the first connected controller. Press `Alt+C` in the overlay to open the controller selection modal and persist your preferred controller across sessions. Press `Alt+Shift+C` to open a live debug modal showing raw axes and button values.
+
+### Default Button Mapping
+
+| Button | Action |
+| ------ | ------ |
+| `A` (South) | Toggle lookup |
+| `B` (East) | Close lookup |
+| `Y` (North) | Toggle keyboard-only mode |
+| `X` (West) | Mine card |
+| `L1` | Play current Yomitan audio |
+| `R1` | Next Yomitan audio track |
+| `L3` (left stick press) | Toggle mpv pause |
+| `Select` / `Minus` | Quit mpv |
+| `L2` / `R2` | Unbound (available for custom bindings) |
+
+### Analog Controls
+
+| Input | Action |
+| ----- | ------ |
+| Left stick horizontal | Move token selection left/right |
+| Left stick vertical | Smooth scroll Yomitan popup |
+| Right stick horizontal | Jump inside popup (horizontal) |
+| Right stick vertical | Smooth scroll popup (vertical) |
+| D-pad | Fallback for stick navigation |
+
+All button and axis mappings are configurable under the `controller` config block. See [Configuration — Controller Support](/configuration#controller-support) for the full options.

+# Overlay Controller Support Design
+
+**Date:** 2026-03-11
+**Backlog:** `TASK-159`
+
+## Goal
+
+Add controller support to the visible overlay through the Chrome Gamepad API without replacing the existing keyboard-only workflow. Controller input should only supplement keyboard-only mode, preserve existing behavior, and expose controller selection plus raw-input debugging in overlay-local modals.
+
+## Scope
+
+- Poll connected gamepads from the visible overlay renderer.
+- Default to the first connected controller unless config specifies a preferred controller.
+- Add logical controller bindings and tuning knobs to config.
+- Add `Alt+C` controller selection modal.
+- Add `Alt+Shift+C` controller debug modal.
+- Map controller actions onto existing keyboard-only/Yomitan behaviors.
+- Fix stale selected-token highlight cleanup when keyboard-only mode turns off or popup closes.
+
+Out of scope for this pass:
+
+- Raw arbitrary axis/button index remapping in config.
+- Controller support outside the visible overlay renderer.
+- Haptics or vibration.
+
+## Architecture
+
+Use a renderer-local controller runtime. The overlay already owns keyboard-only token selection, Yomitan popup integration, and modal UX, and the Gamepad API is browser-native. A renderer module can poll `navigator.getGamepads()` on animation frames, normalize sticks/buttons into logical actions, and call the same helpers used by keyboard-only mode.
+
+Avoid synthetic keyboard events as the primary implementation. Analog sticks need deadzones, continuous smooth scrolling, and per-action repeat behavior that do not fit cleanly into key event emulation. Direct logical actions keep tests clear and make the debug modal show the exact values the runtime uses.
+
+## Behavior
+
+Controller actions are active only while keyboard-only mode is enabled, except the controller action that toggles keyboard-only mode can always fire so the user can enter the mode from the controller.
+
+Default logical mappings:
+
+- left stick vertical: smooth Yomitan popup/window scroll when popup is open
+- left stick horizontal: move token selection left/right
+- right stick vertical: smooth Yomitan popup/window scroll
+- right stick horizontal: jump horizontally inside Yomitan popup/window
+- `A`: toggle lookup
+- `B`: close lookup
+- `Y`: toggle keyboard-only mode
+- `X`: mine card
+- `L1` / `R1`: previous / next Yomitan audio
+- `R2`: activate current Yomitan audio button
+- `L2`: toggle mpv play/pause
+
+Selection-highlight cleanup:
+
+- disabling keyboard-only mode clears the selected token class immediately
+- closing the Yomitan popup also clears the selected token class if keyboard-only mode is no longer active
+- helper ownership should live in the shared keyboard-only selection sync path so keyboard and controller exits stay consistent
+
+## Config
+
+Add a top-level `controller` block in resolved config with:
+
+- `enabled`
+- `preferredGamepadId`
+- `preferredGamepadLabel`
+- `smoothScroll`
+- `scrollPixelsPerSecond`
+- `horizontalJumpPixels`
+- `stickDeadzone`
+- `triggerDeadzone`
+- `repeatDelayMs`
+- `repeatIntervalMs`
+- `bindings` logical fields for the named actions/sticks
+
+Persist the preferred controller by stable browser-exposed `id` when possible, with label stored as a diagnostic/display fallback.
+
+## UI
+
+Controller selection modal:
+
+- overlay-hosted modal in the visible renderer
+- lists currently connected controllers
+- highlights current active choice
+- selecting one persists config and makes it the active controller immediately if connected
+
+Controller debug modal:
+
+- overlay-hosted modal
+- shows selected controller and all connected controllers
+- live raw axis array values
+- live raw button values, pressed flags, and touched flags if available
+
+## Testing
+
+Test first:
+
+- controller gating outside keyboard-only mode
+- logical mapping to existing helpers
+- continuous stick scroll and repeat behavior
+- modal open shortcuts
+- preferred-controller selection persistence
+- highlight cleanup on keyboard-only disable and popup close
+- config defaults/parse/template generation coverage
+
+## Risks
+
+- Browser gamepad identity strings can differ across OS/browser/runtime versions.
+  Mitigation: match by exact preferred id first; fall back to first connected controller.
+- Continuous stick input can spam actions.
+  Mitigation: deadzones plus repeat throttling and frame-time-based smooth scroll.
+- Popup DOM/audio controls may vary.
+  Mitigation: target stable Yomitan popup/document selectors and cover with focused renderer tests.

+# Overlay Controller Support Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add Chrome Gamepad API controller support to the visible overlay as a supplement to keyboard-only mode, including controller selection/debug modals, config-backed logical bindings, and selected-token highlight cleanup.
+
+**Architecture:** Keep controller support in the visible overlay renderer. Poll and normalize gamepad state in a dedicated runtime, route logical actions into the existing keyboard-only/Yomitan helpers, and persist preferred-controller config through the existing config pipeline and preload bridge.
+
+**Tech Stack:** TypeScript, Bun tests, Electron preload IPC, renderer DOM modals, Chrome Gamepad API
+
+---
+
+### Task 1: Track work and lock the design
+
+**Files:**
+- Create: `backlog/tasks/task-159 - Add-overlay-controller-support-for-keyboard-only-mode.md`
+- Create: `docs/plans/2026-03-11-overlay-controller-support-design.md`
+- Create: `docs/plans/2026-03-11-overlay-controller-support.md`
+
+**Step 1: Record the approved scope**
+
+Capture controller-only-in-keyboard-mode behavior, the modal shortcuts, config scope, and the stale selection-highlight cleanup requirement.
+
+**Step 2: Verify the written scope matches the approved design**
+
+Run: `sed -n '1,220p' backlog/tasks/task-159\\ -\\ Add-overlay-controller-support-for-keyboard-only-mode.md && sed -n '1,240p' docs/plans/2026-03-11-overlay-controller-support-design.md`
+
+Expected: task and design doc both mention controller selection/debug modals and highlight cleanup.
+
+### Task 2: Add failing config tests and defaults
+
+**Files:**
+- Modify: `src/config/config.test.ts`
+- Modify: `src/config/definitions/defaults-core.ts`

+- Modify: `src/types.ts`
+- Modify: `config.example.jsonc`
+
+**Step 1: Write the failing test**
+
+Add coverage asserting a new `controller` config block resolves with the expected defaults and accepts logical-field overrides.
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test src/config/config.test.ts`
+
+Expected: FAIL because `controller` config is not defined yet.
+
+**Step 3: Write minimal implementation**
+
+Add the controller config types/defaults/registry/template wiring and regenerate the example config if needed.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test src/config/config.test.ts`
+
+Expected: PASS
+
+### Task 3: Add failing keyboard-selection cleanup tests
+
+**Files:**
+- Modify: `src/renderer/handlers/keyboard.test.ts`
+- Modify: `src/renderer/handlers/keyboard.ts`
+- Modify: `src/renderer/state.ts`
+
+**Step 1: Write the failing tests**
+
+Add tests for:
+
+- turning keyboard-only mode off clears `.keyboard-selected`
+- closing the popup clears stale selection highlight when keyboard-only mode is off
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test src/renderer/handlers/keyboard.test.ts`
+
+Expected: FAIL because selection cleanup is incomplete today.
+
+**Step 3: Write minimal implementation**
+
+Centralize selection clearing in the keyboard-only sync helpers and popup-close flow.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test src/renderer/handlers/keyboard.test.ts`
+
+Expected: PASS
+
+### Task 4: Add failing controller runtime tests
+
+**Files:**
+- Create: `src/renderer/handlers/gamepad-controller.test.ts`
+- Create: `src/renderer/handlers/gamepad-controller.ts`
+- Modify: `src/renderer/context.ts`
+- Modify: `src/renderer/state.ts`
+- Modify: `src/renderer/renderer.ts`
+
+**Step 1: Write the failing tests**
+
+Cover:
+
+- first connected controller is selected by default
+- preferred controller wins when connected
+- controller actions are ignored unless keyboard-only mode is enabled, except keyboard-only toggle
+- stick/button mappings invoke the expected logical helpers
+- smooth scroll and repeat throttling behavior
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test src/renderer/handlers/gamepad-controller.test.ts`
+
+Expected: FAIL because controller runtime does not exist.
+
+**Step 3: Write minimal implementation**
+
+Add a renderer-local polling runtime with deadzone handling, action edge detection, repeat timing, and helper callbacks into the keyboard/Yomitan flow.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test src/renderer/handlers/gamepad-controller.test.ts`
+
+Expected: PASS
+
+### Task 5: Add failing controller modal tests
+
+**Files:**
+- Modify: `src/renderer/index.html`
+- Modify: `src/renderer/style.css`
+- Create: `src/renderer/modals/controller-select.ts`
+- Create: `src/renderer/modals/controller-select.test.ts`
+- Create: `src/renderer/modals/controller-debug.ts`
+- Create: `src/renderer/modals/controller-debug.test.ts`
+- Modify: `src/renderer/renderer.ts`
+- Modify: `src/renderer/context.ts`
+- Modify: `src/renderer/state.ts`
+
+**Step 1: Write the failing tests**
+
+Add tests for:
+
+- `Alt+C` opens controller selection modal
+- `Alt+Shift+C` opens controller debug modal
+- selection modal renders connected controllers and persists the chosen device
+- debug modal shows live axes/buttons state
+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test src/renderer/modals/controller-select.test.ts src/renderer/modals/controller-debug.test.ts`
+
+Expected: FAIL because modals and shortcuts do not exist.
+
+**Step 3: Write minimal implementation**
+
+Add modal DOM, renderer modules, modal state wiring, and controller runtime integration.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test src/renderer/modals/controller-select.test.ts src/renderer/modals/controller-debug.test.ts`
+
+Expected: PASS
+
+### Task 6: Persist controller preference through preload/main wiring
+
+**Files:**
+- Modify: `src/preload.ts`
+- Modify: `src/types.ts`
+- Modify: `src/shared/ipc/contracts.ts`
+- Modify: `src/core/services/ipc.ts`
+- Modify: `src/main.ts`
+- Modify: related main/runtime tests as needed

+
+**Step 2: Run test to verify it fails**
+
+Run: `bun test src/core/services/ipc.test.ts`
+
+Expected: FAIL because no controller preference IPC exists yet.
+
+**Step 3: Write minimal implementation**
+
+Expose renderer-safe getters/setters for the controller config fields needed by the selection modal/runtime.
+
+**Step 4: Run test to verify it passes**
+
+Run: `bun test src/core/services/ipc.test.ts`
+
+Expected: PASS
+
+### Task 7: Update docs and config example
+
+**Files:**
+- Modify: `config.example.jsonc`
+- Modify: `README.md`
+- Modify: relevant docs under `docs-site/` for shortcuts/usage/troubleshooting if touched by current docs structure
+
+**Step 1: Write the failing doc/config check if needed**
+
+If config example generation is covered by tests, add/refresh the failing assertion first.
+
+**Step 2: Implement the docs**
+
+Document controller behavior, modal shortcuts, config block, and the keyboard-only-only activation rule.
+
+**Step 3: Run doc/config verification**
+
+Run: `bun run test:config`
+
+Expected: PASS
+
+### Task 8: Run the handoff gate and update the backlog task
