<<<<<<< HEAD
- **2026-10-21 (BRIEF-4 drawable cache):** Reuse `8ed11cc7`/`ad173490` drawable caching and SDL3 pixel-size event publication. Seven query/event hardware controls match all output hashes; resize and zero-per-frame-query checks pass on Windows and Mac. A loaded repeat before this fix has a 51.795ms host-event span; final performance validation remains open.
=======
- **2026-10-21 (Windows sleep concurrency):** Concurrent guest/render pacers
exposed a shared auto-reset waitable timer: one caller cancels/consumes the
other's wake. Replaced it with FLS-owned timers and synchronized QPC setup.
Eight-sleeper regression fails old source at 10 s and passes the fix in
0.49 s, including timer-handle cleanup. No guest time model changed.
- **2026-10-21 (BRIEF-4 production follow-up):** Remove production-only PGXP diagnostic receipt copies and reuse the FLS-owned Windows sleep timer fix from `2ca004ba`. The PGXP quiet repeat reduces p99 busy from 70.6% to 50.5%, but two >25ms completion gaps remain. Only failing acceptance runs are repeated under the owner minimum-testing rule.
- **2026-10-21 (production R4 follow-up):** Removed debug-only PGXP receipt
writes from no-debug-tools builds; numeric PGXP and word-shadow suites pass.
Added disk-state-anchored applied-input replay and bounded frame/work/span
exports for production measurements. Five focused framework CTests and 26
R4 checks pass on Windows. The owner's stricter default-Ultra acceptance bar
remains open; evidence is in R4 `analysis/render-60fps/SLOWDOWNS.md`. No guest
timing or projection arithmetic changed.

A loaded repeat before this fix has a 51.795ms host-event span; final performance validation remains open.
- **2026-10-21 (BRIEF-4 cap edges):** Apply the display ceiling after supersampling and resolve the physical-monitor supersample policy after creating the window, including fixed presets. Saved large factors cannot exceed the Match display ceiling; legacy unset scales stay intact. Resolution tests pass on Windows/Mac; all 21 R4 production-build CTests pass. Final regeneration and receipt verification pending.
