P0 single-writer / data-integrity finding on exact 19adf2d051c0fce4db88fb378ed9e863ab8af77c.
현재 PR 제목/본문은 Workspace.tsx의 roleMap에서 forEach → for...of만 설명하지만, live effective diff는 그 경계를 더 이상 소유하지 않고 apps/desktop/src/features/score/scoreStorage.ts의 PDF bridge byte validation을 다시 쓰고 있습니다. 이 경계는 이미 canonical score-storage owner #1190 exact **61eddb084b40e63f0a09ec06f661eafa8b7dc23e**이 소유합니다.
더 중요한 것은 #1236 current implementation이 #1190보다 semantic contract를 약화한다는 점입니다. 여기서는 array element에 typeof x === "number"만 검사한 뒤 Uint8Array.from()으로 넘기므로 NaN, Infinity, 음수, 소수, >255 값이 모두 number로 admission되고 typed-array 변환 과정에서 0/모듈러/절삭 값으로 조용히 coercion될 수 있습니다. 반면 #1190은 Number.isInteger(byte) && 0 <= byte <= 255를 동일 순회에서 검증하고 이 hostile set을 fail closed하는 focused regression을 이미 소유합니다. IPC/Tauri bridge response는 외부 입력 경계이므로 이 차이는 단순 micro-optimization이 아니라 byte-truth/data-authority 회귀입니다.
RED:
- current #1236에
[NaN],[Infinity],[-1],[1.5],[256]를 각각 주면Invalid score bridge response가 아니라Uint8Array로 coercion되어 반환되는 것을 고정하십시오. - protected
develop기준 #1236 effective diff와 #1190 diff를 비교해 동일readScorePdfowner boundary를 병렬 소유하고 있음을 검증하십시오. - PR authority text가
roleMapoptimization을 current source라고 주장하면서 실제 source는 scoreStorage를 수정하는 stale-traceability 상태도 fail해야 합니다.
GREEN: 이 PR에서 scoreStorage/source/test 학습 delta를 독립적으로 완성하거나 merge하지 마십시오. #1190 또는 명시적 verified successor 하나가 single-pass validation/copy, byte-domain hostile fixtures, benchmark harness와 관련 evidence를 canonical하게 보존하도록 하고, #1236에서 유효했던 원래 Workspace.roleMap 성능 delta가 아직 존재한다면 그 delta만 owner-safe ancestry로 ordinary-forward 복구하십시오. 만약 #1190이 #1236의 모든 현재 유효 scoreStorage delta를 완전히 승계한다면 그 사실을 exact blob/test/fixture/evidence compare로 입증한 뒤에만 해당 중복 delta를 PR=0으로 볼 수 있습니다.
성능 주장도 분리해야 합니다. forEach/every callback 제거는 방향성 후보일 뿐 unit/lint 통과가 buyer-visible 성능 evidence가 아닙니다. rights-cleared realistic Score PDF payload에서 동일 runtime으로 CPU, allocation/GC/RSS, wall median/p95를 비교하고 semantics parity를 먼저 고정하십시오.
현재 판정: current-title/authority traceability FAIL / scoreStorage single-writer FAIL / byte-domain semantic parity FAIL / #1190 canonical successor candidate PASS / performance evidence FAIL/PENDING.

바이트 값의 정수 및 범위를 검증하십시오.
typeof response[i] === "number"는 바이트 값 검증이 아닙니다. NaN, -1, 256, 1.5가 통과합니다. Uint8Array.from()은 이 값을 변환하므로 잘못된 브리지 응답이 오류 대신 변경된 PDF 바이트로 반환됩니다.
Number.isInteger(byte) && byte >= 0 && byte <= 255를 요구하십시오. 각 경계 밖 값에 대한 거부 테스트도 추가하십시오.

Fleet exact-head review for b49dbf0541ba5ffedce9fb857d7250f390d77d14.
There is a real correctness defect in the current optimization, not just stale title/body metadata. The new loop accepts every value whose typeof is number; Uint8Array.from() then silently coerces values outside the byte domain. Examples: NaN -> 0, Infinity -> 0, -1 -> 255, 256 -> 0, and fractional values are truncated. The new regression only covers a non-number ("a"), so this head can convert malformed bridge data into different PDF bytes instead of failing closed.
Open #1190 is already the bounded canonical readScorePdf owner for this exact bridge boundary. It owns single-pass validation/copy plus the stronger invariant that each element is a finite integer in 0..255, with NaN/Infinity/negative/fractional/>255/non-number coverage and a reproducible benchmark harness. Do not run a parallel scoreStorage production writer here.
RED: on the real readScorePdf boundary, assert rejection of NaN, Infinity, -Infinity, negative numbers, fractions, 256+, and non-numbers; preserve empty/valid byte arrays byte-for-byte. Add a differential fixture proving malformed inputs do not reach PDF rendering as coerced bytes.
GREEN: ordinary-forward any unique valid delta from #1236 into #1190 (or one explicitly designated successor), keep #1190's byte-domain contract, and benchmark the same realistic bridge payloads on one exact head. Title/body/.jules/bolt.md must be current to the actual scoreStorage change, not Workspace.tsx roleMap. The formatter-only test_supply_chain_policy.py delta is foreign to this lane and should remain with its canonical owner rather than be carried here.
Do not close this PR merely because #1190 exists; first verify complete semantic/test/evidence succession.

Preservation / ownership status
이 PR은 Open / Draft / mergeable 상태로 보존합니다. Score bridge delta는 canonical owner #1190보다 약하고 #1176 formatter delta까지 함께 들고 있으므로 독립 merge 대상이 아닙니다.

이 branch는 bridge array에서
Array.every()를 수동 loop로 바꾸지만 validation은typeof value === "number"까지만 수행하고 검증 뒤Uint8Array.from()을 다시 호출합니다. 따라서 strict integer/range admission과 bounded one-pass copy를 제공하지 않습니다.#1190은 현재 한 canonical renderer lane에서 다음을 소유합니다.

지금 단순 Close하지 않습니다. #1190은 아직 #1176 feature branch 위의 Draft이므로 protected/released successor가 아닙니다. #1176 정상 통합 → #865 정상 통합 → #1190 ordinary/non-force reconciliation → fresh exact-head tests/security/review → protected succession이 확인된 뒤 이 branch의 still-valid optimization/test intent가 완전히 승계됐는지 다시 확인하고 closure를 판단합니다.
특정 성능 향상 배수는 주장하지 않습니다. Representative payload, exact runtime/host, repeated measurement와 buyer-path heap/GC/latency evidence가 필요합니다.
