# 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: `planning`
- started_utc: `2026-02-22T00:17:28Z`
- last_update_utc: `2026-02-22T00:17:28Z`

## 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`

## 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.
