Current authority

  • canonical parent: #1273 exact 4c45491dc1441c2b6fae0a3ec290a982a2de15ad, tree d67ee23c4a59a0fae169d394f38fe72d40487e2e
  • exact head: 7ceae5e0c0b98edf17a07a0aa8f74b83d1244440
  • exact tree: 020b73e2c747eb0a9f6e13f12ea44402ae200af8
  • lifecycle: Draft / open / mergeable
  • parent ancestry: 5 ahead / 0 behind
  • effective delta: 4 files

Ordinary two-parent restack

#1273 advanced to repair malformed SARIF helpUri admission. This PR was therefore stale even though its previous tree preserved the earlier OWASP URI mapping. The new exact head is an ordinary two-parent commit with both previous #1269 afa17f1c... and current #1273 4c45491d... in ancestry.

The resulting tree preserves:

Relative to current #1273 the effective files remain exactly:

  • .jules/bolt.md;
  • CHANGELOG.d/1269-sarif-rule-index.md;
  • appguardrail_core/sarif.py;
  • tests/test_sarif.py.

No force update, destructive rebase, source copy from a mutable branch, or valid delta loss occurred.

Exact-tree verification

  • focused SARIF suite: 7/7 passed;
  • production and finding-normalizer compile: passed;
  • conflict-marker and trailing-whitespace checks: passed;
  • current-parent compare: 5 ahead / 0 behind, four effective files;
  • mergeability: true;
  • hosted workflows: none associated at first exact-head fetch; absence is not passing evidence;
  • qualifying exact-head approval: 0.

The prior controlled benchmark remains bounded evidence for the same rule_indices delta: 10,000 findings / 1,000 rules / seven runs, median 0.363498 s → 0.176561 s. It is not end-to-end p95 evidence and is not relabelled as a universal speedup.

Delivery gate

Keep Draft behind #1273. Require #1273 ordinary protected integration first, then terminal hosted Checks and qualifying independent review on this unchanged exact head. Do not transfer predecessor evidence, self-approve, force-push, source-neutrally retrigger, weaken gates, merge, tag or release.

Replaced the $O(N^2)$ `list(rules).index(rule_id)` operation inside
the loop with an $O(1)$ dictionary lookup using `rule_indices`.
This resolves a major performance bottleneck for reports containing
a large number of findings across distinct rules.

In @.jules/bolt.md:
- Line 82: Update the SARIF generation documentation in bolt.md to describe the
original repeated rule lookup cost as O(M × R), where M is the number of
findings and R is the number of unique rule IDs, then describe the
rule_indices-based lookup as O(M + R). Retain the explanation that each
rule_indices lookup is average O(1).

Please review exact head afa17f1cb65478ec8dba5fc5f027a71b4a17fdfc. The preceding concurrent head removed stacked #1273 security behavior and tests; this normal descendant restores the audited tree. Do not transfer findings or approvals from predecessor heads.

@seonghobae I will review commit afa17f1cb65478ec8dba5fc5f027a71b4a17fdfc as an independent head. I will not transfer findings or approval from predecessor heads.

Duplicate PR #1330 exact 92fcc78a…/tree 5d28bcfe… has been verified as completely carried by this successor: identical rule_indices production semantics, plus this PR's repeated-rule regression, CHANGELOG, bounded measurement, exact O(M × R) model, and #1273 fail-closed URI prerequisite. #1330 is being retired unmerged by complete successor carryover; this does not change #1269's Draft status or delivery gates.
