Scope

Canonical chart-export de-duplication owner. services/analysis-engine/src/bandscope_analysis/exports/chart.py uses insertion-ordered dictionaries instead of repeated list-membership scans for active role ids, display names, cue values, and rehearsal-priority lines. First-occurrence order is preserved while ordinary-string membership changes from repeated linear scans to average constant-time keyed lookup.

Exact current identity

  • Protected target: develop@314ddeae7b775a4957594b599358c8255617eb2e.
  • Exact head: 4d154e6c1dcf840c0cbac76f789c30d58903b9e0.
  • Open, Draft; predecessor checks/reviews do not transfer.
  • Fresh protected-base comparison: behind_by=0; semantic delta is exactly five owner files: .jules/bolt.md, CHANGELOG.md, exports/chart.py, and the two chart-export de-duplication regression suites.

Non-force protected-base adoption

Intervening protected work after the previous owner head b0d403ee0e9b7849b74ac5e8afe3e42d424106c2 was adopted through ordinary two-parent commit 3e34efef996c8e6c2e4c3833413a229f908c0606, using the current protected tree as the base and overlaying only the five canonical owner blobs. force=false was used. Follow-up 4d154e6c1dcf840c0cbac76f789c30d58903b9e0 corrected the Unreleased changelog composition so the protected #1165 workflow-consolidation line is retained alongside this optimization. No protected workflow or supply-chain delta is reversed.

Correctness / safe-failure boundary

The optimization normalizes string-like values through _hashable_text before they become dictionary keys or footer values. Regressions cover duplicate role ids/display names/cue values/priorities, unhashable string subclasses, hashable subclasses, truthiness-overriding subclasses, first-occurrence order, and rehearsalPriority normalization. Malformed caller-controlled string subclasses therefore cannot introduce new hashing/truthiness exceptions relative to the pre-optimization list path.

Succession / overlap

Earlier #849, #1154, and #1161 chart de-duplication proposals are already represented here; their valid behavior was transferred before closure and their checks/reviews do not transfer.

#1176 proposes the same four list-to-dictionary substitutions on current protected develop, but directly admits arbitrary str subclasses as dict keys and provides no dedicated chart-export regression for the malformed-text compatibility boundary; its third file is formatting-only test_supply_chain_policy.py. The useful O(N²)-removal intent is therefore a strict subset of this canonical owner, while the simpler implementation would regress the safe-failure contract. No #1176 check/review evidence transfers.

Claim boundary

This is an algorithmic-complexity repair: affected duplicate-membership traversal becomes linear expected traversal for ordinary strings. It is not a measured end-to-end latency claim. Do not infer a percentage or buyer-visible speedup without a representative benchmark.

Merge gate

Keep Draft and unmerged until every applicable required exact-head gate is terminal-success on unchanged head 4d154e6c1dcf840c0cbac76f789c30d58903b9e0, zero actionable review findings remain, a qualifying independent non-author last-push approval exists, and ordinary protected-branch acceptance succeeds. No self-approval, bypass, gate weakening, force-push, destructive rebase, or branch-local workaround for the known retired-CodeQL-context protection defect.

@coderabbitai review

Please review exact head 4d154e6c1dcf840c0cbac76f789c30d58903b9e0 after its ordinary protected-base adoption. Focus on _hashable_text compatibility/safe-failure semantics, first-occurrence ordering, malformed str subclass behavior, and whether the five-file tree preserves protected #1165 state without importing #1176's formatting-only delta. Predecessor evidence is non-passing.

@seonghobae Reviewed exact head 4d154e6c1dcf840c0cbac76f789c30d58903b9e0 against protected base 749511c3ad4000090048718f685c6bee6b3d2c25.

No blocking findings in the requested scope.

  • HEAD exactly matches the requested commit.
  • The protected #1165 tree is retained. The final tree differs from #1165 in only five files.
  • The #1176 formatting-only change in services/analysis-engine/tests/test_supply_chain_policy.py is not present.
  • _hashable_text fails closed for non-string, unhashable, and exception-raising string subclasses. It normalizes accepted text to a built-in str before truthiness and dictionary use.
  • Dictionary assignment preserves first-occurrence order for active role IDs, display names, cue values, and name: priority entries.
  • Regression coverage includes duplicate role IDs and graph nodes, display names, cue values, cross-section priorities, unhashable subclasses, hashable subclasses, and truthiness-raising subclasses.

The sandbox did not execute repository tests. This conclusion is based on the exact tree and static regression coverage.
