- alias: `codex-kiku-modal-overlay`
- mission: `Fix Kiku field-grouping modal overlay visibility restore when modal closes`
- status: `handoff`
- branch: `main`
- started_at: `2026-02-22T22:05:02Z`
- heartbeat_minutes: `5`

## Current Work (newest first)
- [2026-02-22T22:07:38Z] handoff: added failing regression test for hidden->modal->close restore path; patched `field-grouping-overlay` to sync visible overlay state for external senders; focused tests green.
- [2026-02-22T22:05:02Z] intent: investigate Kiku modal + overlay visibility restore regression; add failing test first, then minimal fix.
- [2026-02-22T22:06:10Z] progress: traced leak to `createFieldGroupingOverlayRuntime` path using `sendToActiveOverlayWindow` without syncing `visibleOverlayVisible` state.

## Files Touched
- `docs/subagents/INDEX.md`
- `docs/subagents/collaboration.md`
- `docs/subagents/agents/codex-kiku-modal-overlay-20260222T220502Z-r4m1.md`
- `src/core/services/field-grouping-overlay.ts`
- `src/core/services/field-grouping-overlay.test.ts`

## Assumptions
- Bug reproduces when visible overlay is initially hidden and Kiku modal auto-opens overlay.
- Existing callback restore path should remain source of truth (hide on resolve/cancel).

## Open Questions / Blockers
- none

## Next Step
- User validation in real overlay flow (hidden visible overlay -> Kiku modal open/close -> hidden restored).
