From 1f40e9d8fa3d3ee5d9bf6888a5897b78ab200208 Mon Sep 17 00:00:00 2001 From: Chris Wolfgang <210299580+Chris-Wolfgang@users.noreply.github.com> Date: Tue, 21 Jul 2026 20:16:43 -0400 Subject: [PATCH 1/3] ci: add per-PR perf-regression detection (#144) Adds perf-regression.yaml: runs the BenchmarkDotNet suite on the PR and compares against the gh-pages dev/bench baseline via github-action-benchmark, commenting on regressions. Path-filtered to src/** and benchmarks/**; report-only (fail-on-alert:false, auto-push:false) given shared-runner noise. Ported from D20-Dice; canonical refreshed pins.

Set SHELLCHECK_OPTS to --severity=warning so it gates on warning+ (real issues), not style nits. - zizmor flagged error[dangerous-triggers] on pr.yaml's pull_request_target. That is the intentional *gated* pattern (runs from trusted main, checks out PR refs, re-fetches config from main). Added a documented dangerous-triggers ignore for pr.yaml to .zizmor.yml and wired --config .zizmor.yml into the zizmor step (it is not auto-discovered). - Enabling the config also activates the existing unpinned-uses:hash-pin policy, which then flagged pr.yaml's three remaining tag-pinned actions (checkout@v7, setup-dotnet@v5, upload-sarif@v4). SHA-pinned them to the repo canonical commits (also fixing a real SHA-pin-convention gap). Verified locally: zizmor --config at high severity reports no findings.

Re-pin every codeql-action reference (init / analyze / upload-sarif across pr, codeql, actions-audit, scorecard, semgrep) to e4fba868 — the actual commit v4 resolves to (verified via the GitHub tags API) — so each # v4 comment now matches.
