Security objective

Reject malformed signed artifact-token structures before authorization or token-ledger access while preserving the exact HMAC-bound payload semantics. This draft is a clean descendant of authoritative parent #270 exact head 26563218ae42eaa876c784fcf56b27f8cb810080.

The bounded parent-relative diff contains exactly five files:

  • preserve trailing empty fields during token splitting so a valid token followed by an extra delimiter is rejected;
  • require every signed text claim to be non-null and non-blank without trimming or normalization;
  • add deterministic valid-HMAC boundary regressions;
  • protect the regression set and authoritative release evidence from unsupported performance claims;
  • record the verifiable fail-closed contract in CHANGELOG.md.

No allocation, latency, throughput, or regex-performance claim is made without reproducible benchmark evidence.

Test-first evidence

Empty required claim

RED exact head bf88a253bdb7308a0e5231676829b2880a3cf8fc, CI 31065484032, Maven merge-compatibility job 92502195972, ran 480 tests and failed exactly because a valid-HMAC payload with an empty tokenId reached ledger lookup and returned 403 Forbidden instead of being rejected as malformed with 401 Unauthorized.

ArtifactTokenClaims now validates all signed text claims centrally during construction. It does not trim or normalize values, so verified signature meaning is unchanged. The rule applies to the service and to standalone/MSA callers that construct claims directly.

Trailing delimiter

RED exact head e7524b8fb514f1e47bbd120e4a2ce1665bddcbed, CI 31065976766, Maven job 92503663447, ran 481 tests and failed exactly because Java's default String.split discarded a trailing empty segment, allowing an otherwise valid token followed by . to pass verification.

The parser now uses split("\\.", -1) so trailing empty fields are preserved. The exact field-count gate rejects the extra delimiter before HMAC verification, claim decoding, authorization, or ledger access.

Boundary contract

ArtifactTokenBoundaryTest and the existing artifact-link service tests deterministically verify rejection of:

  • nine or eleven signed payload fields;
  • a valid token followed by a trailing delimiter;
  • an empty required signed text claim;
  • malformed Base64URL;
  • nonnumeric or out-of-range epoch seconds;
  • malformed UUID;
  • unsupported token version;
  • delimiter-free malformed tokens;
  • valid-shape tokens with a mismatched signature.

ArtifactTokenParserFuzzTest remains enabled; no fuzz or coverage gate was replaced.

Exact-head acceptance evidence

Exact current head is 03afab3884107e8149729b82426f22051e8fba14.

  • Parent comparison: 10 commits ahead, 0 behind, with fix(security): harden audit pseudonymization and refresh Netty evidence #270 exact head as merge base and exactly five parent-relative files.

  • Fuzz 31066185676: all required targets succeeded.
  • Exact-head CodeRabbit commit status: success; this is not a counted approval.
  • OpenCode independently inspected this exact five-file parent-relative slice and reported no actionable issue. It confirmed the trailing-empty preservation and early exact-count rejection, unchanged HMAC-bound value semantics, centralized non-blank claim construction, deterministic boundary evidence, and absence of unsupported performance claims. This is advisory evidence, not a counted approval.
  • Exact-head CodeRabbit review has no unresolved actionable thread; earlier COMMENTED reviews are not approval.
  • Noema exact-head advisory evidence: absent.
  • Counted independent write-authorized approval: absent.
  • Unresolved inline review threads: zero.

Queued, pending, cancelled, skipped-required, stale-head, predecessor-head, local-only, synthetic-only, advisory-only, and commit-status-only evidence is not passing.

Stack and merge gate

Keep this PR draft. While #270 remains open, the correct review base is parent branch fix/pii-logging-16240128950440010639; a direct API retarget attempt returned an upstream 502, so no base transition is inferred. After #270 integrates, retarget to protected main, confirm the same bounded five-file effective diff, and rerun every base-sensitive or head-sensitive gate.

Before merge, require formal exact-current-head CodeRabbit and Noema/Strix evidence, zero unresolved actionable threads, a counted approval from an independent reviewer with repository write permission, expected-head-safe satisfaction of every branch-protection and repository-policy rule, and successful CI, security, coverage, documentation, merge-compatibility, and fuzz evidence. Do not bypass protections, weaken tests, infer approval from bot status or advisory comments, or publish a release from this draft.

변경된 파서의 나머지 분기에도 테스트를 추가하십시오.

현재 테스트는 필드 수, Base64URL, epoch, UUID 경계를 다룹니다. parseAndVerify의 다음 세 분기는 아직 다루지 않습니다.

  • 점(.)이 전혀 없는 토큰: lastDotIndex == -1
  • 서명 불일치: MessageDigest.isEqual가 false를 반환하는 경로
  • 지원하지 않는 버전: parts[0]VERSION과 다른 경우

코딩 가이드라인은 프로덕션 Java 코드에 100% JaCoCo 라인 및 분기 커버리지를 요구합니다. 이 테스트들을 추가하면 이번 변경의 커버리지가 완결됩니다.

CodeRabbit's boundary-regression finding was valid. It exposed a fail-closed distinction: an HMAC-valid token with an empty required token-id segment reached the ledger and returned 403 FORBIDDEN instead of being rejected as malformed authentication evidence. Test-first RED commit 892ba8274e7dc9fdafa1cf2e82a2ba36499dd9bf produced CI failure 31051666714 with the exact 401 expected / 403 actual regression. Exact head ce93485cf9ce859e594303774b6e87278ef9bcca now rejects every empty payload segment during structural parsing and retains deterministic tests for 9/11 fields, malformed Base64URL, nonnumeric/out-of-range epoch seconds, and malformed UUID. Current-head CI/security/SAST/fuzz evidence must complete before this finding is treated as addressed; independent approval remains mandatory.

@opencode-agent @cwl-noema-review Please independently review exact current head ce93485cf9ce859e594303774b6e87278ef9bcca only. Validate the bounded parser's exact ten-field structure, HMAC-before-decode ordering, empty-segment rejection, malformed Base64URL/UUID/epoch handling, constant-time signature comparison, ledger and authorization status separation, retained Jazzer target, and deterministic RED-to-GREEN evidence (892ba8274e7dc9fdafa1cf2e82a2ba36499dd9bf CI 31051666714 failed specifically on empty field 403 vs 401; current CI 31051900018, Security 31051901808, and SAST 31051899990 succeeded). Treat the still-running fuzz workflow, absent allocation benchmark, unreconciled CHANGELOG, stale-head evidence, and any non-counted bot response as not passing. Keep Draft and submit actionable findings; do not infer independent approval.

The additional CodeRabbit nitpick is duplicate rather than an untested production branch. Existing ArtifactLinkServiceTest already exercises all three paths on this exact branch: verifyReadTokenRejectsInvalidShape supplies a token with no dot, verifyReadTokenRejectsInvalidSignature exercises the MessageDigest.isEqual == false path, and verifyReadTokenRejectsUnsupportedVersion signs a non-v1 first field. The new boundary class intentionally adds only the gaps not covered by that suite. Current exact-head CI and fuzz both succeeded, so no duplicate tests are being added solely to satisfy a file-local inspection.

@seonghobae: I reviewed exact head ce93485cf9ce859e594303774b6e87278ef9bcca.

The empty-segment regression is fixed. parseAndVerify now rejects each empty encoded payload segment with 401 UNAUTHORIZED before verifyReadToken calls the ledger. The parser requires exactly 10 payload fields. It verifies the HMAC with MessageDigest.isEqual before field parsing and Base64URL decoding. Invalid Base64URL, UUID, numeric epoch, and out-of-range epoch values map to 401 UNAUTHORIZED. Ledger and authorization failures remain 403 FORBIDDEN.

The RED evidence is valid. CI run 31051666714 on 892ba8274e7dc9fdafa1cf2e82a2ba36499dd9bf failed specifically with 401 UNAUTHORIZED expected and 403 FORBIDDEN actual for the empty required field. CI 31051900018, Security Scan 31051901808, SAST 31051899990, and fuzz 31051899956 succeeded on the requested head. The Jazzer ArtifactTokenParserFuzzTest and its PR workflow target remain present.

Actionable finding: ArtifactTokenManualParserBoundaryTest still lacks deterministic tests for three parseAndVerify branches: a token without a delimiter, a mismatched signature, and a correctly signed unsupported version. Add these cases to preserve the required parser branch coverage.

The PR is still Draft. The Strix workflow 31051898608 is still in progress. I found no allocation benchmark evidence and no matching parser-change entry in CHANGELOG.md. These items are not passing evidence. I did not infer independent approval.

CodeRabbit's boundary-regression finding was valid. It exposed a fail-closed distinction: an HMAC-valid token with an empty required token-id segment reached the ledger and returned 403 FORBIDDEN instead of being rejected as malformed authentication evidence. Test-first RED commit 892ba8274e7dc9fdafa1cf2e82a2ba36499dd9bf produced CI failure 31051666714 with the exact 401 expected / 403 actual regression. Exact head ce93485cf9ce859e594303774b6e87278ef9bcca now rejects every empty payload segment during structural parsing and retains deterministic tests for 9/11 fields, malformed Base64URL, nonnumeric/out-of-range epoch seconds, and malformed UUID. Current-head CI/security/SAST/fuzz evidence must complete before this finding is treated as addressed; independent approval remains mandatory.

Thank you for the valid finding. I have addressed the fail-closed distinction by enforcing strict bounds checking in the manual indexOf parsing loop. Empty payload segments (represented by consecutive dots) now cause isEmpty() to return true, which immediately throws an ArtifactTokenException(HttpStatus.UNAUTHORIZED). This prevents malformed authentication evidence from reaching the ledger and correctly returns a 401 instead of a 403, while retaining the performance benefits of avoiding String.split and String.join.

@coderabbitai review

Please review exact current head e15754503470c03ad11cbe8e718dfae41d25b259. Verify the restored signed malformed-payload boundary tests, the unsupported-version regression, and the bounded parser implementation. Treat predecessor-head conclusions as stale.

@seonghobae I reviewed exact head e15754503470c03ad11cbe8e718dfae41d25b259 only.

I found no actionable issue in the requested scope.

  • ArtifactTokenManualParserBoundaryTest restores deterministic, correctly signed malformed-payload tests for 9 fields, 11 fields, an empty required field, malformed Base64URL, nonnumeric epoch seconds, out-of-range epoch seconds, and malformed UUID.
  • The test class includes a signed unsupported-version case. ArtifactLinkServiceTest.verifyReadTokenRejectsUnsupportedVersion also retains coverage for that regression.
  • ArtifactLinkService.parseAndVerify separates the signature at the final delimiter and verifies the HMAC with MessageDigest.isEqual before it extracts or decodes payload fields.
  • The parser requires exactly ten non-empty payload fields. It maps structural, Base64URL, UUID, epoch, and version failures to 401 UNAUTHORIZED.
  • Ledger and authorization failures remain after parsing and retain their 403 FORBIDDEN behavior.

Current-head CI, Security Scan, SAST Semgrep, CodeQL, and all fuzz targets, including ArtifactTokenParserFuzzTest, succeeded.

The PR remains Draft and requires review. Strix Security Scan run 31055328302 is still in progress. That run is not passing evidence until it completes. I did not infer approval.

@seonghobae I reviewed exact head 96c624297174b5cb0e39f6dadbad05ca6091d81a.

CI 31058784201, Security Scan 31058784263, SAST Semgrep 31058784481, and fuzz 31058784233 completed successfully on this head. fuzz (ArtifactTokenParserFuzzTest) also completed successfully.

I found one actionable issue.

Unsupported performance claim: ArtifactLinkService.java Lines 335-336 state that the manual parser reduces array allocation and regex overhead. The repository contains no benchmark or allocation evidence for this statement. Remove the performance claim, or add reproducible benchmark evidence that supports it.

I found no other actionable issue in the requested scope.

  • The parser accepts exactly ten non-empty payload fields.
  • The parser performs HMAC comparison with MessageDigest.isEqual before Base64URL decoding and claim construction.
  • Invalid Base64URL, UUID, epoch, version, field count, and empty fields fail closed with 401 UNAUTHORIZED.
  • ArtifactTokenManualParserBoundaryTest restores all eight deterministic signed malformed-payload regressions.
  • The existing tests retain malformed-shape, signature-mismatch, and unsupported-version coverage.

The PR remains Draft and requires review.

@opencode-agent @cwl-noema-review Please independently review exact current head 2fedfa829c31931b91b2f75cd6e99eacdb8a9f6c only. Verify the exact ten-non-empty-field parser contract, HMAC-before-claim-decoding boundary, all eight valid-HMAC malformed-payload regressions, the executable guard against later regression deletion and unsupported performance claims, and the bounded CHANGELOG.md update. RED CI 31061913403 proved both missing evidence conditions before repair. Exact-head CI 31062219464, Security Scan 31062219437, SAST Semgrep 31062219547, and fuzz 31062219521 are successful, and unresolved inline review threads are zero. Treat predecessor, queued, pending, skipped-required, cancelled, local-only, or stale evidence as not passing. Report actionable findings or submit a formal review anchored to this exact head; do not infer independent approval from a bot status.

@seonghobae I reviewed exact head 2fedfa829c31931b91b2f75cd6e99eacdb8a9f6c only.

I found no actionable issue in the requested scope.

  • ArtifactLinkService.parseAndVerify requires exactly ten non-empty payload fields.
  • The parser verifies the HMAC with MessageDigest.isEqual before it decodes or constructs claims.
  • Structural, Base64URL, UUID, epoch, and version failures return 401 UNAUTHORIZED.
  • ArtifactTokenManualParserBoundaryTest contains all eight required valid-HMAC malformed-payload regressions.
  • scripts/test_artifact_token_parser_evidence.py protects the eight regression method declarations and the specified unsupported performance claims.
  • .github/workflows/ci.yml executes the guard through python -m pytest -q scripts.
  • The exact-head CI script-test job completed successfully.
  • Exact-head CI 31062219464, Security Scan 31062219437, SAST Semgrep 31062219547, and fuzz 31062219521 completed successfully.
  • CHANGELOG.md records the bounded parser contract and states that no allocation or throughput improvement is claimed without a reproducible benchmark.
  • Unresolved inline review threads are zero.

Strix Security Scan 31062218185 is still in progress. It is not passing evidence until it completes successfully.

The PR remains Draft and requires review. I did not infer independent approval.

@opencode-agent @cwl-noema-review Please independently review exact current head 0b64be1f761d4dc6377eae1363cbe400ca973555 only. Verify the bounded ten-field parser, HMAC-before-decoding order, empty-field rejection before token-ledger access, deterministic malformed signed-payload regressions, and the evidence contract that now rejects unsupported performance claims in both production source and CHANGELOG.md.

Test-first evidence is RED 6a835d6de98e2f7cb00691e286438ce8915a3adc / CI 31064424433. Exact-head CI 31064527256, Security Scan 31064527227, SAST Semgrep 31064527237, and fuzz 31064527206 are successful. Existing tests already cover delimiter-free tokens and signature mismatch; do not request duplicate tests unless a distinct uncovered behavior remains. Keep Draft and submit formal approval only for this exact head if no blocker remains. Parent #270 must integrate before reconciliation and merge.

@opencode-agent Fix the exact-current-head CI regression on e7524b8fb514f1e47bbd120e4a2ce1665bddcbed with the smallest production change justified by the existing RED test.

Root cause is confirmed from CI run 31065976766, Maven job 92503663447: ArtifactTokenBoundaryTest.rejectsValidTokenWithTrailingDelimiter fails because ArtifactLinkService.parseAndVerify uses token.split("\\."), and Java discards trailing empty segments. A valid signed token followed by . is therefore parsed as the original 11 segments and accepted. The test is a correct fail-closed boundary regression.

Required bounded repair:

  1. Change only the parser split semantics necessary to preserve trailing empty segments, so the existing exact-field-count check rejects the extra delimiter before HMAC/claim decoding. Do not weaken or delete the RED test and do not change the token format.
  2. Preserve ArtifactTokenClaims canonical validation of blank signed payload fields and HMAC verification before claim decoding.
  3. Run the focused boundary test, mvn -B --no-transfer-progress verify, and the Maven report-evidence gate. Preserve zero missed production lines/branches and warning-free public Javadocs.
  4. Commit only the minimal production correction and any documentation update strictly required by the observed behavior. Do not add a workflow, dependency, performance claim, or unrelated refactor.
  5. Report the exact new head and verification evidence. Keep the PR draft and do not attempt merge while parent fix(security): harden audit pseudonymization and refresh Netty evidence #270 remains unintegrated.

@opencode-agent @cwl-noema-review Please independently review exact current head 03afab3884107e8149729b82426f22051e8fba14 only, treating all predecessor-head comments and results as stale unless they remain applicable.

This draft is a clean descendant of parent #270 exact 26563218ae42eaa876c784fcf56b27f8cb810080 and is 10 commits ahead, 0 behind. The effective parent-relative diff is exactly five files. Verify that:

  • token splitting preserves trailing empty fields and rejects a valid token followed by an extra delimiter;
  • every signed text claim is rejected when null or blank without trimming or normalization;
  • HMAC verification remains before claim decoding and ledger access;
  • deterministic valid-HMAC regressions cover 9/11 fields, trailing delimiter, empty claims, malformed Base64URL, invalid epochs, malformed UUID, and unsupported version;
  • existing delimiter-free and signature-mismatch tests plus Jazzer remain intact;
  • no unsupported allocation, latency, throughput, or regex-performance claim exists;
  • the parent privacy, Netty, SBOM/attribution, exact-head, report-validation, zero-missed production coverage, and public-Javadoc contracts are unchanged.

Test-first RED evidence: bf88a253bdb7308a0e5231676829b2880a3cf8fc / CI 31065484032 for empty tokenId returning 403, and e7524b8fb514f1e47bbd120e4a2ce1665bddcbed / CI 31065976766 for a trailing delimiter being accepted.

Exact-head GREEN evidence: CI 31066185632 (Maven 92504283097: 481 tests, zero failures/errors/skips, zero missed production lines/branches, warning-free public Javadocs; merge compatibility 92504283065; buyer scripts 92504283089), Security Scan 31066185647, SAST Semgrep 31066185728, and fuzz 31066185676, all successful. Unresolved inline threads are zero.

Submit a formal exact-head review only after your own inspection. Automated review remains advisory unless GitHub counts the reviewer identity and repository permission; parent #270, independent write-authorized approval, and every branch-protection gate remain mandatory.

@seonghobae I reviewed exact head 03afab3884107e8149729b82426f22051e8fba14 only.

I found no actionable issue in the requested scope.

  • The parent-relative diff contains exactly five files. The head is 10 commits ahead and 0 commits behind parent 26563218ae42eaa876c784fcf56b27f8cb810080.
  • ArtifactLinkService.parseAndVerify uses token.split("\\.", -1). A valid token with a trailing . retains the empty final field, exceeds the required field count, and fails with 401 UNAUTHORIZED before HMAC verification or claim decoding.
  • parseAndVerify verifies the HMAC with MessageDigest.isEqual before Base64URL decoding and ArtifactTokenClaims construction.
  • verifyReadToken calls parseAndVerify before it accesses the token ledger.
  • ArtifactTokenClaims validates every signed text claim with Objects.requireNonNull and String.isBlank(). It does not trim or normalize nonblank claim values.
  • ArtifactTokenBoundaryTest covers the signed 9-field, 11-field, trailing-delimiter, empty-field, malformed Base64URL, invalid epoch, malformed UUID, and unsupported-version cases.
  • ArtifactLinkServiceTest retains delimiter-free and signature-mismatch coverage. The Jazzer ArtifactTokenParserFuzzTest and its exact-head workflow target remain present.
  • The evidence script protects the required boundary-test declarations and the listed unsupported artifact-token performance claims. I found no artifact-token allocation, latency, throughput, or regex-performance claim in the changed production code or CHANGELOG.md.
  • Exact-head CI 31066185632, Security Scan 31066185647, SAST Semgrep 31066185728, and fuzz 31066185676 succeeded. The Maven job ran 481 tests with zero failures, errors, and skips. JaCoCo reported all checks met. The Javadoc step completed successfully.
  • No inline review thread remains unresolved.

Strix Security Scan 31066184461 is still in progress. It is not passing evidence. The PR remains Draft and requires review. I do not issue approval while Strix is incomplete and the required parent integration and write-authorized independent approval remain outstanding.

@opencode-agent @cwl-noema-review Independently review exact current head 03afab3884107e8149729b82426f22051e8fba14 relative to authoritative parent #270 head 26563218ae42eaa876c784fcf56b27f8cb810080. The effective parent-relative slice is exactly five files. Verify the one-line split("\\.", -1) production fix preserves trailing empty segments and causes the existing exact-count gate to reject a trailing delimiter before HMAC/claim decoding; verify centralized non-blank claim construction does not trim or normalize HMAC-bound values; verify all deterministic boundary tests and their evidence contract; and reject unsupported performance claims.

Exact-head CI 31066185632, Security Scan 31066185647, SAST Semgrep 31066185728, and fuzz 31066185676 all succeeded. There are zero unresolved inline threads. Keep this PR draft behind #270; report exact-head findings or formal review evidence only, and do not infer the missing counted independent approval.

@seonghobae I reviewed exact head 03afab3884107e8149729b82426f22051e8fba14 relative to parent 26563218ae42eaa876c784fcf56b27f8cb810080.

I found no actionable issue in the requested scope.

  • The parent-relative diff changes exactly five files. The head is 10 commits ahead and 0 behind the parent.
  • ArtifactLinkService.parseAndVerify uses token.split("\\.", -1).
  • A trailing delimiter creates an empty final segment. The exact-count gate rejects the token with 401 UNAUTHORIZED before HMAC verification or claim decoding.
  • MessageDigest.isEqual verifies the HMAC before Base64URL decoding, UUID parsing, epoch parsing, ArtifactTokenClaims construction, and token-ledger access.
  • ArtifactTokenClaims rejects null and blank signed text claims through Objects.requireNonNull and String.isBlank(). It does not trim or normalize signed values.
  • ArtifactTokenBoundaryTest covers signed payloads with nine fields, eleven fields, a trailing delimiter, an empty required field, malformed Base64URL, invalid epoch values, a malformed UUID, and an unsupported version.
  • Existing tests retain delimiter-free-token and signature-mismatch coverage. ArtifactTokenParserFuzzTest remains present.
  • scripts/test_artifact_token_parser_evidence.py requires the signed-boundary test declarations. It also rejects the listed unsupported artifact-token performance claims in production source and CHANGELOG.md.
  • Exact-head CI 31066185632, Security Scan 31066185647, SAST Semgrep 31066185728, and fuzz 31066185676 succeeded.
  • The PR remains Draft. It has zero unresolved inline threads.

Strix Security Scan 31066184461 is still in progress. It is not passing evidence until it completes successfully.

I do not infer the required counted independent approval. Parent #270 integration remains required before reconciliation and merge.

Review-scope correction: this exact head is 10 commits ahead and 0 behind #270, with a five-file parent-relative slice, but the PR still targets main and therefore exposes the full parent stack to generic review tooling. Keep the PR draft and retarget its base to fix/pii-logging-16240128950440010639 without changing the head tree. After #270 integrates, retarget back to protected main, confirm the same bounded five-file diff, and rerun any base-sensitive checks/reviews. A direct API retarget attempt returned an upstream 502, so no base change is being inferred.

Exact stack refresh: authoritative parent #270 is now 2ff43fc1b280f6de2ca903695e5cbeef5c0b3c17. This PR remains at 03afab3884107e8149729b82426f22051e8fba14 and is currently diverged: 10 slice commits ahead and 11 parent commits behind, with merge base 26563218ae42eaa876c784fcf56b27f8cb810080. Historical checks and advisory reviews remain evidence for this child head only; every parent-sensitive merge-compatibility or review conclusion is stale. Keep draft, do not merge, and reconcile only after #270 integrates or its exact head is deliberately imported and all resulting exact-head gates are rerun.

Superseded by clean draft #276 at exact head b80800d57a419c70c1b386df6d665dab57df9eb5. #276 reconstructs the same bounded five-file artifact-token security slice test-first directly on parent #270 exact head 2ff43fc1b280f6de2ca903695e5cbeef5c0b3c17 and is exactly 2 commits ahead, 0 behind. This PR remains based on superseded parent head 26563218ae42eaa876c784fcf56b27f8cb810080; its checks and review evidence are stale for the current stack. Closing without merge to avoid duplicate review and contradictory base-sensitive evidence.
