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.

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

Exact break location (window options vs renderer preload/load path vs toggle handler state).

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