Current boundary

This is a Draft performance/behavior-equivalence candidate with one independently justified loading-contract repair; it is not a completed performance claim.

  • protected/base: develop@2c328875e00e86537df3e965170be80532571cad
  • exact head: 13cf9c03012bb7dfd3968488c6ea4f6101f6c2ae
  • effective protected-base delta: cloud-sync.js, index.html, CHANGELOG.md
  • generated .jules/bolt.md appendix is restored byte-for-byte to protected authority

Existing RED contract

Protected tests/e2e/scopeweave.spec.js already requires exactly one modulepreload link for each of cloud-sync.js, analytics.js, and app.js, while protected index.html currently declares only the app.js hint. The two added hints therefore repair an existing executable browser contract independently of any speedup claim. The contract establishes resource-discovery markup, not buyer-visible TTI.

Map candidate

openAttachmentsModal() and openCommentsModal() previously resolved each rendered task id with Array.find() over the current task list. The candidate snapshots the current task array once per successful refresh into a Map, so the lookup portion changes structurally from repeated linear scans to one map construction plus keyed lookups. That source-level complexity reduction is real, but it is not evidence of a material buyer-visible latency or GC improvement.

Intervening-delta repair and #644 succession

After reviewed head bf2ac10fe1978ecd1fa578de68dadc52f77015df, four normal descendants reintroduced a repository-wide .jules/bolt.md prescription asserting a general O(N*M) rule. Fresh compare showed that was the only tree delta. Normal descendant 034e1b5c0eebedf97a43e2a33cf9aa4bb2b1e969 restores the exact protected Bolt blob; history is retained.

Sibling #644@56dbb956a50e48bf1b62fb02b9960afc6d2b81e8 contributed the same two modulepreload links, plus generated repository doctrine and an Unreleased line that claimed TTI improvement without measured browser evidence. This lane now carries the complete valid preload semantic and a corrected code-current changelog entry. Fresh audit found no unique focused test, fixture, or product contract only on #644, so #644 was closed only after complete valid succession here; no predecessor GREEN or merge authority transferred.

Required behavioral evidence

Before promotion, prove that attachments/comments still resolve task labels correctly for normal, missing-task and refreshed-state cases; empty/error modal behavior and keyboard/focus behavior must remain unchanged. The Map must be rebuilt on every refresh and must not become durable task authority.

For the preload repair, run the existing Playwright contract on this exact head. Before making a performance claim, additionally inspect the current browser request graph and ensure no duplicate/unnecessary fetch or CSP/static-serving regression across the supported static-server/Pages paths.

Performance acceptance

If the Map refactor remains justified by performance, compare protected base and this exact candidate under the same browser/runtime and representative/right-cleared project sizes. Record task count, attachment/comment cardinality, repeated samples, median/p95 render latency, main-thread profile and allocation/GC evidence. Do not use unit/E2E pass counts or asymptotic notation alone as buyer-visible performance evidence. If the measured gain is immaterial, keep the independently justified preload contract and prefer the simpler protected modal lookup.

Keep Draft until one unchanged exact head has terminal applicable CI/Security/SAST/CodeQL/E2E evidence, zero valid current-head findings, and qualifying independent review. No self-approval, no-op retrigger, scanner suppression, gate weakening, force-push or destructive rebase.

cloud-sync.js의 openAttachmentsModal 및 openCommentsModal에서 발생하던 O(N*M) 시간 복잡도 병목 현상을 해결했습니다. 반복문 내에서 Array.prototype.find()를 호출하던 taskName 클로저를 개선하여, 반복문 외부에서 작업(task)들의 O(1) 조회용 Map을 사전 계산(precompute)하도록 변경했습니다. 또한, index.html에 cloud-sync.js 및 analytics.js에 대한 modulepreload 링크를 추가하여 모듈 로딩 성능을 최적화하고 간헐적인 E2E 테스트(modulepreload 확인) 실패 문제를 해결했습니다.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to bf2ac

Attachment and comment lists now use faster task lookups, but tasks identified only by activity or phase can display their IDs instead of readable names. Align the fallback fields before merge to avoid this presentation regression.

작업명 fallback을 기존 표시 규칙과 맞춰 주세요.

현재 taskNamenametask만 확인합니다. activity 또는 phase만 가진 작업은 첨부 및 코멘트 목록에서 실제 작업명 대신 ID로 표시됩니다. Line 1209의 작업 선택 목록과 buildWeeklyReport의 작업명 규칙은 이 필드들을 지원합니다. 두 taskName 함수에서 동일한 fallback 순서를 사용하세요.

수정 예시
-      return t ? (t.name || t.task || id) : id;
+      return t ? (t.name || t.task || t.activity || t.phase || id) : id;

Also applies to: 1384-1384
