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.

; move all avgs to watch MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit avg metrics aren't representative — one slow frame in 500+ skews the mean even when steady-state behavior is fine. p90 captures the steady state, p99 the tail, but avg is noisy in a way that mixes both. Move every *.avg metric to the watch tier (still emitted in the PR comment, just never fails the build). The PR comment now shows only gated metrics by default per renderer (p90 tight, p99 loose, to_screen.p90 tight) and collapses watch metrics under a
Watch-only metrics (N) — informational, never fail the build block. Reduces ~38 rows per renderer to ~3 in the default view; reviewers expand if they want to inspect the tail distributions.
