Agent Session: opencode-task105-unsafe-casts-20260222T194704Z-zfcm

• alias: opencode-task105-unsafe-casts
• mission: Execute TASK-105 eliminate unsafe non-test runtime casts in main boundaries end-to-end without commit.
• status: done
• started_utc: 2026-02-22T19:47:35Z
• last_update_utc: 2026-02-22T21:56:30Z

Intent

• Load TASK-105 context from Backlog MCP and collect exact unsafe cast hotspots.
• Write implementation plan via writing-plans skill with test-first steps and verification gates.
• Execute plan with executing-plans skill, parallelizing independent slices where safe.

Assumptions

• TASK-105 scope excludes test-only casts and non-main-runtime paths.
• Existing compile/test lanes are authoritative for regression detection.

Phase Log

• 2026-02-22T19:47:35Z Session started; loaded backlog workflow overview, subagent coordination docs, and TASK-105 details.
• 2026-02-22T19:52:30Z Wrote plan at docs/plans/2026-02-22-task-105-unsafe-runtime-casts.md, set TASK-105 In Progress, and executed runtime cast-elimination with parallel subagents.
• 2026-02-22T21:10:04Z Completed cast elimination in non-test target scope; follow-up type harmonization done for tray/bootstrap/test contracts.
• 2026-02-22T21:55:38Z Verification complete: cast scan after=0, targeted runtime tests green, test:core:src green; temporarily blocked on unrelated note-update-workflow.test.ts TS errors during bun run build.
• 2026-02-22T21:56:30Z Re-ran bun run build after concurrent compile-fix; build passes. TASK-105 finalized Done in Backlog with AC/DoD evidence.

Next Step

• TASK-105 complete. Optional next step: stage/commit focused TASK-105 diff once user requests commit.
