 - [ ] #4 Malformed payloads are handled gracefully and test-covered
 <!-- AC:END -->
 
+## Implementation Plan
+
+<!-- SECTION:PLAN:BEGIN -->
+Plan of record (2026-02-22):
+1) Add central typed IPC contract module at `src/shared/ipc/contracts.ts` and migrate `src/core/services/ipc.ts`, `src/core/services/anki-jimaku-ipc.ts`, and `src/preload.ts` from string literals to contract constants/types.
+2) Add runtime IPC payload validators at `src/shared/ipc/validators.ts` for externally supplied payloads (runtime option id/direction/value boundary, subsync request shape, overlay modal, subtitle position, and kiku/jimaku payloads where renderer-supplied).
+3) Wire validators at IPC boundaries so malformed payloads are handled gracefully (return structured `{ ok: false, error }` for invoke handlers or no-op/log for fire-and-forget channels) and avoid unsafe `as` casts in boundary code.
+4) Reduce unsafe casts in runtime IPC wiring (`src/main/dependencies.ts`, `src/main.ts`, IPC composer generics) by narrowing types before domain calls.
+5) Add/extend IPC tests for malformed payload behavior (`src/core/services/ipc.test.ts`, `src/core/services/anki-jimaku-ipc.test.ts`), then run `bun run build`, `bun run test:core:src`, and `bun run test:core:dist`.
+6) Update `docs/architecture.md` with central IPC contract and boundary-validation conventions; then finalize TASK-80 AC/DoD evidence in Backlog MCP.

+Plan-of-record (2026-02-22, codex-task82-smoke-20260222T002523Z-3j7u)
+
+Goal
+- Add deterministic e2e smoke coverage for launcher -> mpv IPC socket -> app overlay start/stop runtime wiring.
+- Run suite in CI + release quality gates with actionable failure artifacts.
+- Document command, coverage, and release-checklist linkage.
+
+Execution slices (parallel where safe)
+1) Launcher smoke harness (core implementation)
+   - Create launcher/smoke.e2e.test.ts with fake mpv + fake app fixtures in temp dir.
+   - Validate startup path, socket readiness, app --start args/env, and post-run --stop behavior.
+   - Emit actionable artifact logs under .tmp/launcher-smoke/<run-id>.
+
+2) Script + workflow wiring (can run in parallel after command exists)
+   - package.json: add test:launcher:smoke:src and include in launcher lane.
+   - .github/workflows/ci.yml: run launcher smoke suite and upload smoke artifacts on failure.
+   - .github/workflows/release.yml: mirror quality-gate step and failure artifact upload.
+
+3) Docs wiring (parallel with workflows)
+   - docs/development.md: command usage + what it validates + artifact path.
+   - docs/installation.md: release/checklist reference to launcher smoke gate.
+
+4) Validation + closure
+   - Run focused lane: bun run test:launcher:smoke:src and bun run test:launcher.
+   - Run integration lane: bun run test:fast.
+   - Run dist confidence lane: bun run build && bun run test:smoke:dist (or record unrelated blockers).
+   - Update TASK-82 AC/DoD checks with exact evidence and final summary.
+
+Scope guardrails
+- No commit/push in this run.
+- Keep smoke suite dependency-free (local fakes only).
+- If new required scope appears, pause and request user scope decision before expanding AC.
