## 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.

generated regression
Restore the validated preservation tree while retaining the intervening generated commit in ancestry. The reverted delta reintroduced the non-equivalent if(offset > max) loop, removed the note-derived geometry regression, and added an unmeasured performance claim already rejected in favor of canonical #1170.

## 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.

+## 2026-09-23 - Replace reduce with for...of loop on large arrays
+
+**Learning:** Using `Array.prototype.reduce()` on large arrays incurs significant callback function call overhead in tight loops.
+**Action:** Replace `.reduce()` with a `for...of` loop to iterate and compute the accumulated value directly, resulting in faster execution by avoiding massive O(N) callback overhead on critical paths.

Subject: [PATCH 09/17] repair(perf): restore GrooveMap preservation after
repeated generated regression
Retain the intervening generated commit in ancestry while restoring the validated preservation tree. The reverted delta again changed NaN semantics, removed the note-derived geometry regression, reintroduced an unprofiled performance claim, and copied the #1176 formatter delta.

Subject: [PATCH 14/17] preserve(perf): collapse GrooveMap duplicate to
provenance-only
Remove the generated GrooveMap/test delta from the active diff. Canonical #1170 already contains the semantics-preserving max-offset scan and the useful >10s rendered-geometry regression, while #1254 owns shared timing admission. Keep this branch only as ancestry/provenance until verified protected succession satisfies PR-0.
