+## Done this session (M-25) — 3 commits, port-layer QoL
+
+Free-roam QoL pass, `port/` only, zero `src/` / game-logic change. Full
+review sheet: **`docs/M-25-QOL-REVIEW.md`**. All defaults reproduce prior
+behavior exactly.

+- **`9ebed821` — `[Video]` ge007.ini knobs.** `Video.VSync` / `FpsCap` /
+  `MSAA` (1/2/4/8) / `TextureFilter` (0 nearest, 1 bilinear) / `Fullscreen`,
+  wired in `video.c videoInit`. Plus **config auto-migration**: `config.c`
+  now rewrites `ge007.ini` once when the build registers a key the file
+  never had (so a new section actually appears) — an up-to-date file with a
+  user comment is left untouched.
+- **`5a7a1035` — `tools_pc/playtest.sh`** takes a level *name*
+  (`playtest.sh bunker2`) or number, `--list` prints the 21-level table, and
+  a crash now auto-runs `addr2line` on the faulting PCs.
+- **`863f436b` — `[Input]` ge007.ini knobs.** `MouseYScale`,
+  `MouseSmoothing` (0 = off = today), `PadDeadzone` (7000), `PadTriggerPct`
+  (23), `PadLookInvertY`.
+- Verified per commit: build green, `-level_09` crash-free to frame 620 @
+  91.6% (unregressed), `-level_20` crash-free.
+- **New bug logged (not fixed — out of scope):** Silo `-level_20` freezes
+  ~3 s in on the silo→Bond camera descent (no crash; capture wedges
+  ~frame 320). Reproduces on a clean pre-M-25 build. User-reported. Goes
+  with the in-level playtest / camera-transition work.

 Last full re-sweep: 2026-08-29 (M-22), after D134 landed (SP/DP task-done
 event no longer dropped into a full sched interruptQ — the "frame-2 hang"
 that M-13..M-21 wrote off as D117/machine-load flakiness). Build = HEAD
