Agent Session: opencode-task79-runtime-reducers-20260221T235652Z-n4p7

• alias: opencode-task79-runtime-reducers
• mission: Execute TASK-79 explicit runtime state transitions/reducers in main via writing-plans + executing-plans (no commit).
• status: done
• started_utc: 2026-02-21T23:56:52Z
• last_update_utc: 2026-02-22T00:10:51Z

Intent

• Load TASK-79 from Backlog MCP; capture plan in task.
• Produce implementation plan doc under docs/plans/.
• Execute code/test/docs updates end-to-end without commit.

Planned Files

• src/main.ts
• src/main/state.ts
• src/main/state.test.ts

Assumptions

• Backlog task TASK-79 exists and is ready for execution.
• Existing startup/IPC/overlay behavior must remain unchanged.
• Parallel subagents can own independent slices (state domains/tests/docs) without overlap.

Phase Log

• 2026-02-21T23:56:52Z Started; loaded backlog overview + TASK-79 context; beginning planning.
• 2026-02-22T00:06:10Z Slice A implementation: added explicit AniList state transition helpers + initializers in src/main/state.ts; rewired migrated src/main.ts AniList writes through transitions; added focused reducer tests in src/main/state.test.ts; focused bun test src/main/state.test.ts blocked by Bun runtime missing node:sqlite.
• 2026-02-22T00:10:51Z Finalized TASK-79: switched state.ts import to direct mpv-render-metrics module (removes node:sqlite test coupling), focused state/anilist invariant tests passing, build + test:core:src passing, backlog TASK-79 marked Done.
