FTL only stocks redfin (Pixel 5 / Adreno 620) on Android 11 (API 30), so swap the Adreno job to a52sxq (Galaxy A52s, Adreno 642L) on Android 14 — the next-closest mid-range Snapdragon device available. Bump the Mali job from oriole-32 → oriole-33 (same Pixel 6 hardware, Android 13) for the same reason. While diagnosing the previous CI run on FTL, the Pixel 6 hit a real NPE in CoreEngine::nativeSendCameraFrame: AHardwareBuffer_lock returned non-zero for the camera-side buffer, leaving cpuData null, and the subsequent memcpy SIGSEGV'd. Check both lock return codes + pointer non-null before copying, and drop the frame on failure instead of crashing. Also add an `ls` assertion after each perfetto capture in FrameLatencyCapture — UiAutomation.executeShellCommand swallows exit codes and stderr, so a misbehaving perfetto used to silently pass the test with zero traces produced. The assertion gives us a clear failure with the output-dir listing in the message.

Drop .github/workflows/build.yml — its job is byte-identical to the build job in benchmark.yml (which already gates PRs). Main-branch push builds go away; re-add as a separate workflow if/when needed. 2. Per-PR comment with the consolidated p50/p90/p99 delta table: - compare-baseline.py learns --output-md FILE. - Each benchmark-{adreno,mali} job writes comparison-*.md alongside results-*.json and uploads it with the existing artifact. - New `comment` job runs after both (if: always() so regressions still show), downloads both artifacts, and upserts a single PR comment via actions/github-script (marker comment to find-and-update). Merge gating is unchanged — the benchmark-{adreno,mali} jobs still fail on regression, so branch protection blocks merge as before. 3. New .github/workflows/baselines.yml — manual workflow_dispatch: - Optional run_id input (default: latest Benchmark run on the branch). - Downloads benchmark-results-{adreno,mali}, copies results-*.json over baseline-*.json, commits to the same branch. - Next Benchmark run sees a populated baseline and turns green, making a previously-red "needs baseline refresh" PR mergeable without a manual commit.

Gate calibration — sub-ms metrics like frame_native_proc.avg (~0.7 ms baseline) trivially trip the percent gate on noise: a 0.1 ms jitter becomes +14% even though it's far below any frame-budget significance. Add an absolute floor per tier; a metric passes when EITHER |Δ%| ≤ tolerance_pct OR |Δabs| ≤ abs_floor. Real regressions exceed both thresholds, pure relative noise on tiny absolutes is filtered. tight: ±5% AND ±0.5 ms loose: ±10% AND ±0.5 ms (or ±5 frames for dropped_frames counters) PR-comment layout — group metrics by renderer (OpenGL ES vs Vulkan) in two sub-tables with the renderer prefix stripped from the row keys, so the same stage in gl/vk lines up visually for side-by-side reading. New Δabs column next to Δ% makes the absolute jitter obvious at a glance (handy when a flagged metric turns out to be sub-ms noise). Also clarifies the PR-comment text about how to dispatch the Baselines workflow now that the file is finally landing on the default branch.
