Agent Session: opencode-task80-ipc-contract-20260222T001728Z-obrv

• alias: opencode-task80-ipc-contract
• mission: Execute TASK-80 IPC contract typing + runtime payload validation via writing-plans + executing-plans (no commit).
• status: done
• started_utc: 2026-02-22T00:17:28Z
• last_update_utc: 2026-02-22T00:56:00Z

Intent

• Load TASK-80 from Backlog MCP and capture implementation plan before edits.
• Strengthen typed IPC channel contracts and runtime payload validation at boundaries.
• Reduce unsafe unknown casts in IPC handlers and add malformed payload coverage.

Planned Files

• src/main/ipc.ts
• src/main/runtime/*
• src/shared/ipc/*
• src/main/**/*.test.ts
• docs/architecture.md

Files Touched

• src/shared/ipc/contracts.ts
• src/shared/ipc/validators.ts
• src/core/services/ipc.ts
• src/core/services/anki-jimaku-ipc.ts
• src/preload.ts
• src/main/dependencies.ts
• src/main.ts
• src/main/runtime/composers/ipc-runtime-composer.ts

• src/core/services/ipc.test.ts
• src/core/services/anki-jimaku-ipc.test.ts
• package.json
• docs/architecture.md

Assumptions

• TASK-80 scope is main-process IPC boundary; keep external behavior/backward compatibility.
• Existing validation helpers may exist and should be reused over introducing heavy deps.
• Parallel subagents can split contracts/validation/tests/docs with non-overlapping files.

Phase Log

• 2026-02-22T00:17:28Z Session started; read backlog overview and TASK-80 details; beginning planning.
• 2026-02-22T00:21:00Z Plan written to docs/plans/2026-02-22-task-80-ipc-contract-validation.md and recorded in Backlog TASK-80.
• 2026-02-22T00:55:30Z Implemented IPC contract/constants + validators and rewired main/preload/anki-jimaku IPC boundary handlers with runtime payload checks and graceful malformed handling.
• 2026-02-22T00:56:00Z Validation complete: bun run build, bun run test:core:src, bun run test:core:dist all passing; TASK-80 finalized Done in Backlog.
