Builds, fast tier, walk 21425/21425, seams bit-identical, floor 7.884 mm, 18/18 hashes = v225, captures 23/23. Headless near-ready vs pre-merge: SW +11..14%, other six cells faster. UE start->LOD0-2 2.23-2.73 -> 2.22-2.51 s. 30 m/s UE: near coverage 43.4 -> 40.2%, far holes 3.14 -> 3.46%, p99 11.25 -> 10.80 ms, worst 13.97 -> 13.27 ms.

# Linux127 — smooth-tunnel merge
|
||
|
||
Target: `aeb60bb` on `merge/smooth-tunnels`.
|
||
|
||
Build, fast-tier, walkability, seam, floor, determinism, and capture checks pass. The UE moving comparison shows a repeatable coverage drop and is the item to review before landing.
|
||
|
||
- Clang and GCC headless builds pass. UE builds pass: c743 baseline 157/157 actions; merge 29/29, using `-NoUBA -MaxParallelActions=4`.
|
||
- Fast tier passes (259 checks; 5 diagnostic checks). Walkability is 21,425/21,425. Four seam pairs (4,900 shared samples) are bit-identical. Floor probe maximum is 7.884 mm.
|
||
- All 18 owner4/owner2 Clang/GCC W1/W8/W12 hash runs match the L125 v225 baselines.
|
||
- L80 timing protocol on a quiet machine (load 0.69, CPU idle 99.4%): five interleaved measurements per cell, W8/W12 across all four strates. Merge vs L125 is within -4.05% to +2.83% near-ready and -4.58% to +0.95% whole-view. Vs c743, S0 is slower (+10.90% to +14.33% near, +1.26% to +3.52% whole); the other six cells are faster.
|
||
- UE startup reaches full LOD0–2 in all four strates: c743 2.232–2.726 s; merge 2.221–2.514 s. Far-apply CVar reads back as 1 and produces applies in every start and moving run.
|
||
- Five 30 m/s movement runs per build: median near coverage 43.36% → 40.22%; far holes 3.14% → 3.46%; tick p99 11.25 → 10.80 ms; worst tick 13.97 → 13.27 ms. Both builds reach 100% near coverage and zero far holes after stopping. The lane works; moving coverage remains lower on the merge.
|
||
- 23/23 L125 poses rendered and verified from the merge binary; 19 pass pixel quality, 4 show visible low-contrast geometry. See [`captures/INDEX.md`](captures/INDEX.md) and [`captures/COMPARE.html`](captures/COMPARE.html).

No source fix was made. Logs and summaries are in `Saved/Linux/l127`. An early probe wrapper wrote to the L125 probe output; the L125 binary regenerated it, with restoration checksums recorded in `Saved/Linux/l127/restore-l125-probe.log`.
