Summary

  • Make problem-registry:check reject Problem constructors that accept an Error, an Error union, or an error-named unknown value without forwarding it through super(..., { cause }).
  • Keep current intentional exceptions in an allowlist that requires an owner, reason, and expiry date; reject stale or unused entries.
  • Cover direct and guarded forwarding, normalized aliases, spreads, union narrowing, computed keys, and mutations that mask a dropped cause.

Closes #2455

Validation

Elevated profile for a repository verification gate. Head: af7c975e82f1358f98d4b5e608b3836fb4ff2d9f; inspected trunk: 67a0380e0a52d44a20039d806920876c6f6ecadc.

  • Cause-focused registry tests: 11 passed; negative-control fixtures failed before the relevant fixes.
  • Problem registry check: passed, 793 codes from 761 discoveries. Oxlint and Oxfmt: passed.
  • Two independent reviews of the final detection changes: passed with no actionable findings.
  • Exact-head GitHub CI: validate, repository-contracts, docs-sync-check, and benchmark-gate passed. The other impact-selected checks, including core-verification, coverage-security, and companion, also passed (Actions runs 36017516546, 36017516177, and 36017516319).
  • The local full-file test and pre-push monorepo hook did not complete under host contention; the exact-head CI supplies repository-wide verification.

Integration

The change is limited to the registry gate, its allowlist, and fixtures. Existing package constructors remain separate issue work. The current allowlist contains nine reviewed exceptions.

Summary by CodeRabbit

Walkthrough

Problem 레지스트리 검사에 Error.cause 전달 분석을 추가했다. 전달되지 않는 생성자는 진단한다. 만료일과 소유 정보가 있는 allowlist 예외를 검증한다. 테스트는 전달 방식과 예외 검증 사례를 다룬다.

Changes

Layer / File(s) Summary
생성자 cause 전달 분석
scripts/problem-registry.mts
Problem 서브클래스 생성자에서 Error 계열 파라미터와 super() 옵션의 cause 전달 여부를 분석한다. 별칭, 조건 분기, 가드, 스프레드 형태도 검사한다.
검사 연결 및 allowlist 검증
scripts/problem-registry.mts, scripts/problem-cause-allowlist.json
새 진단을 기존 preflight 검사에 연결한다. allowlist 스키마와 항목을 검증하고, 미사용 예외를 진단한다. allowlist에는 9개 예외 항목이 있다.
진단과 예외 테스트
scripts/tests/problem-registry.spec.ts
cause 미전달 진단, 여러 전달 형태, allowlist 필수 필드·만료·미사용 항목·기준 항목 수 검사를 테스트한다.

Merge Risk: 🔵 Low · up to 4994b

The new check that makes Problem subclasses forward their original error can still miss some deliberately obscured ways of dropping the cause. Examples include mutating the options object through a type assertion or through a conditional reassignment. This makes the gate less strict than intended, but it does not affect application behavior. Merging is low risk; fixing these gaps now or as a follow-up would tighten enforcement.

corresponding package fix and record its reference with the relevant entry if
the schema supports it; add a warning beginning seven days before expiry only if
the existing allowlist flow can support it without disrupting checks or artifact
sync.

In `@scripts/problem-registry.mts`:
- Around line 850-863: Update the mutation tracking around mutatedAliases to
recognize delete operations on property or element accesses and mark the target
identifier as mutated. Propagate mutation state across aliases that reference
the same object so mutation through one alias invalidates the others.
- Around line 1107-1109: Update the cause-detection logic and isCauseFreeSpread
to resolve static computed keys such as string literals and treat members that
can define cause, or whose keys cannot be resolved, as cause overrides. Ensure
accessors and methods named cause are detected rather than skipped.
