## Current Work (newest first)
- [2026-02-22T07:45:58Z] progress: Added `src/core/services/overlay-window-config.test.ts` red test for explicit `webPreferences.sandbox=false`; patched `src/core/services/overlay-window.ts` with `sandbox: false`; verified focused tests + full build pass.
- [2026-02-22T07:44:40Z] test: Added red regression in `src/renderer/error-recovery.test.ts` proving `resolvePlatformInfo` incorrectly preferred preload layer over query layer; patched `src/renderer/utils/platform.ts` to prioritize `?layer=` and reran tests/build green.
- [2026-02-22T07:34:50Z] intent: Initialize session record, associate work with TASK-107, inspect overlay runtime + renderer regressions after rebase.

## Files Touched
- `backlog/tasks/task-107 - Fix-post-rebase-overlay-toggle-regression.md`
- `docs/subagents/agents/codex-overlay-toggle-regression-20260222T073450Z-q7m4.md`
- `docs/subagents/INDEX.md`
- `docs/subagents/collaboration.md`
- `src/renderer/error-recovery.test.ts`
- `src/renderer/utils/platform.ts`
- `src/core/services/overlay-window.ts`
- `src/core/services/overlay-window-config.test.ts`

## Assumptions
- Regression likely introduced by recent rebase merge in main/runtime overlay wiring.
- Existing overlay regression tests can be extended for red-green fix.

## Open Questions / Blockers
- Exact break location (window options vs renderer preload/load path vs toggle handler state).

## Next Step
- Hand off fix summary + validation commands to user for runtime confirmation on host machine.
