+## 2026-08-16 - Graph traversal memory optimization
+**Learning:** Using `frozenset` unions inside a tight dependency path graph traversal loop (like `cargo_lock_has_named_dependency_path`) creates significant memory allocation overhead, becoming a major performance bottleneck for large lockfiles.
+**Action:** Use a single shared `set` tracking `(current_node, state)` pairs to achieve O(1) loop allocations and drastically reduce execution time without sacrificing correctness.

Subject: [PATCH 10/13] fix(supply-chain): restore simple dependency-path cycle
 semantics

Bolt reapplied a shared (package_key, matched_count) cache on top of the
already-restored simple-path walk. That cache lets one package key satisfy
two owner-chain positions through a cycle. Restore path-local frozenset
prevention, keep the cycle and distinct-key regressions in two test
modules, drop the unauthorized pdfjs-dist Trivy ignore, and record the
unsafe optimization as a rejected change.

 ## 2026-07-13 - Array.from mapping optimization
 **Learning:** Using `Array.from({ length: N }).map(...)` creates an intermediate array of `undefined` values which requires memory allocation and garbage collection, adding O(N) unnecessary overhead in frequently re-rendered UI components.
 **Action:** Use `Array.from({ length: N }, (_, index) => ...)` to map elements directly during array creation, avoiding intermediate allocations.
-## 2026-08-16 - Graph traversal memory optimization
-**Learning:** Using `frozenset` unions inside a tight dependency path graph traversal loop (like `cargo_lock_has_named_dependency_path`) creates significant memory allocation overhead, becoming a major performance bottleneck for large lockfiles.
-**Action:** Use a single shared `set` tracking `(current_node, state)` pairs to achieve O(1) loop allocations and drastically reduce execution time without sacrificing correctness.

Subject: [PATCH 13/13] fix(supply-chain): restore simple-path cycle
 regressions after Bolt rewrite

Head bcf22eea replaced the validated frozenset walk with recursive DFS and
deleted the cycle/distinct-key tests plus the simple-path policy citation.
Restore the locked iterative walk, both regression modules, and the Cormen
et al. (2022) owner-chain authority so the next rewrite cannot drop the lock.

+## Named dependency-path authority
+
+`scripts/checks/verify_supply_chain.py` treats a Cargo owner chain as a
+*simple path*: a package key may appear at most once on a candidate walk
+(Cormen et al., 2022, Appendix B.4). A shared
+`(package_key, matched_count)` cache is not an equivalent optimization.
+On a cycle such as `root → alpha@1 → beta → alpha@1 → charlie`, that cache
+can reuse `alpha@1` to satisfy a second `alpha` position and falsely accept
+the chain. Distinct keys that share a name (`alpha@1` then `alpha@2`) remain
+valid. Do not reintroduce a global state cache to save `frozenset` copies.
+Keep cycle and distinct-key regressions in
+`services/analysis-engine/tests/test_supply_chain_dependency_path_cycles.py`.
