🟡 New vulnerability suppression added without documentation
The new CVE-2026-16633 line silences a scanner finding with no rationale comment and no exp: revisit date, unlike every other entry in the file. AGENTS.md requires any .trivyignore entry to be narrow and documented, so this suppression violates the repository's stated supply-chain rule.
Prompt for agents
The added .trivyignore entry CVE-2026-16633 has no explanatory comment and no exp:YYYY-MM-DD revisit date, unlike the two entries above it and contrary to the AGENTS.md rule that only a genuine false positive may be added as a narrow, documented entry. Either remediate the underlying vulnerability by bumping the affected dependency in the relevant lockfile, or, if it is truly a false positive, add a documented comment block explaining the CVE, the affected package, why it is not exploitable in BandScope, and an exp: revisit date matching the existing convention.

📝 Info: GrooveMap maxTime no longer propagates NaN
The new loop uses if (n.offset > max), which skips a NaN offset, while the old reduce used Math.max and propagated NaN into maxTime. Behavior is identical for finite offsets. For a NaN offset the new code keeps a finite denominator instead of breaking the whole timeline, so it is more robust, but it contradicts the PR's own stated goal of preserving Math.max semantics.

🔍 PR reverts security hardening beyond its stated scope
The description claims only three files change, but the diff reverts several security controls: pdfjs-dist downgraded from 6.2.108 to 6.1.200; loadScorePdf drops enableXfa: false and useWorkerFetch: false; persist-credentials: false removed from workflow checkouts; the undici pin/override and the npm-runtime pinning plus lock-validation CI job removed. These reintroduce previously remediated dependency vulnerabilities and weaken CI gates. Confirm each revert is intended before merge.

🟨 Fail-closed PDF parser flags removed
loadScorePdf now calls getDocument with only data, dropping enableXfa: false and useWorkerFetch: false. XFA form activation and worker-side resource fetching revert to upstream defaults on the untrusted-PDF path instead of being explicitly disabled.

🟨 GITHUB_TOKEN persisted in CI workspace again
The checkout steps drop persist-credentials: false, so the job token is written into the workspace .git config and readable by every later build step and third-party tool run in the job. The same removal appears across the CI, release, and security-audit workflows.

🔍 Broad security revert in a perf-scoped PR
The stated scope is a GrooveMap performance tweak, but the diff also reverts npm runtime pinning, the undici pin/override, PDF loader hardening, the firstRangeSqueeze feature, and several tests/docs. The removals are internally consistent (no dangling references), but confirm these reverts are intended and not an artifact of a stale merge base.

📝 Info: GrooveMap max loop silently changes NaN handling
The old reduce used Math.max, which returns NaN once any offset is NaN and poisons every note's position. The new loop's if (n.offset > max) skips NaN offsets, so maxTime stays finite. Behavior differs only for non-finite offsets; the description claims Math.max is used but the committed code uses the comparison form.

🟨 Undocumented Trivy suppression hides a fixable vulnerability
The added CVE-2026-16633 entry suppresses a repo-wide CRITICAL/HIGH Trivy finding with no rationale and no expiry. The gate policy requires narrow, documented false-positive entries only, so a real fixable vulnerability can be masked indefinitely.

🟨 PDF loader stops disabling XFA and worker resource fetching

[tool.coverage.run] no longer sets branch = true and the branch-coverage regression test was deleted. The 100% statement gate still runs so builds pass, but branch arcs are no longer measured, weakening the coverage gate the docs describe as hard.

Repair finding
This PR is kept open as a preservation lane, but it is not merge-ready. Fresh comparison against protected
develop@314ddeae7b775a4957594b599358c8255617eb2eshows current headfa1ced9a388d5a3b6740b7254c9f0db8c34383c3is diverged: ahead 38 / behind 2 and currently differs in 31 files, not the three files claimed by the stale body.The branch currently carries unrelated destructive drift outside the intended GrooveMap performance slice, including repository workflow reductions, lock/dependency churn, removal of PDF hardening tests/docs, removal of npm runtime verification, removal of first-range rehearsal behavior/tests, removal of Python branch/security contract tests, and other source changes. Those are repair findings, not reasons to discard valid GrooveMap work and not evidence that the protected branch should be weakened.
Valid GrooveMap delta
The intended semantic delta remains small: preserve the historical ten-second timeline floor and compute the maximum note offset with a linear scan that avoids reducer callback dispatch. Complexity remains O(N). No universal speedup multiplier is accepted without representative BandScope profiling.
A newer clean lane, #1170, contains the same narrow reduce-to-loop idea plus focused component tests and has been converted to Draft while its unsupported O(N)/"5x" claims are corrected. #1170 does not inherit any CI/review/status evidence from this PR.
Preservation / repair plan
Do not force-push, destructive-rebase, bypass-merge, or close this PR merely because the branch is stale. Before any eventual closure, enumerate every valid unique semantic/test/fixture/contract/documentation delta on this branch and either:
develop, orThe 31-file current branch drift must not be merged as-is. Prior workflow/review/check evidence bound to old heads such as
38e1027d...is stale for current headfa1ced9a...and is non-passing. Keep Draft until current-head scope is repaired and fresh exact-head repository/central gates plus a qualifying independent last-push approval pass.
