# Agent Session: opencode-task93-sync-20260221T070842Z-71c6

- alias: `opencode-task93-sync`
- mission: `Synchronize TASK-85 closure tracking and child-task status in Backlog`
- status: `done`
- started_utc: `2026-02-21T07:08:42Z`
- completed_utc: `2026-02-21T07:11:58Z`
- backlog_task: `TASK-93`

## Intent

- Load TASK-93 + TASK-85 + related child tasks from Backlog MCP.
- Build execution plan via writing-plans skill.
- Execute plan via executing-plans skill.
- Update Backlog task metadata/notes/checklists to satisfy TASK-93 AC.

## Planned Files/Surfaces

- `backlog/tasks/task-93 - Synchronize-TASK-85-closure-tracking-and-child-task-status.md` (via MCP)
- `backlog/tasks/task-85 - Refactor-large-files-for-maintainability-and-readability.md` (via MCP)
- Child task tickets linked to TASK-85 (via MCP)
- `docs/subagents/INDEX.md` (own row only)
- `docs/subagents/collaboration.md` (append-only note)

## Assumptions

- Backlog already initialized (folder exists).
- TASK-85 was recently marked Done and needs consistency cleanup.

## Heartbeat Log

- `2026-02-21T07:08:42Z` session started; reading backlog + planning context.
- `2026-02-21T07:11:58Z` execution complete; TASK-85 synchronized and TASK-93 finalized Done.

## Outcome

- Created plan: `docs/plans/2026-02-21-task-93-sync-task85-closure-plan.md`.
- Updated `TASK-85` description + implementation notes with child ownership map and ordered remaining scope.
- Updated `TASK-93` implementation notes, checked all AC/DoD items, set final summary, marked status Done.
- No product-code changes; backlog/process/documentation surfaces only.
