Closes #132.

The draft defines the status claim for any JWT (§6.1), and JWT credentials use it too. So the Token Status List no longer sits behind sd-jwt.

Names

I kept the names the issue proposed:

• module status_list
• feature status-list
• variant CredentialStatus::StatusClaim

Changes

• New module status_list:
  • It holds Status, StatusListRef, StatusMechanism, StatusList, StatusListToken, StatusType and StatusListError.
  • With did-web it also holds StatusListCheck, in status_list/check.rs.
  • It is an upper-layer module beside vc, sd_jwt_vc, domain_linkage and linked_vp, and uses vc for Jwt and JwtClaims.
  • sd_jwt_vc/status.rs moved with git mv, so its history follows.
• Features:
  • New status-list = ["vc", "dep:miniz_oxide"].
  • sd-jwt = ["vc", "status-list", "dep:getrandom"].
  • status-list is listed in default too. It was already on there through sd-jwt.
  • The crate-internal numeric_date helpers are now gated on status-list.
• CredentialStatus::SdJwt is now CredentialStatus::StatusClaim, behind status-list:
  • vc::validation parses and checks the status claim of JWT credentials whenever status-list is on.
  • Without it, the claim still fails under StatusPolicy::Strict and is ignored otherwise.
  • This is the only break cargo semver-checks reports (enum_variant_missing), hence the !.
• Deprecated old paths:
  • sd_jwt_vc::{Status, …, StatusType} and sd_jwt_vc::validation::StatusListCheck remain for one release, with since = "0.3.0".
  • They are #[deprecated] type aliases rather than re-exports, because #[deprecated] on a pub use has no effect (Allow deprecating a re-export rust-lang/rust#30827). I checked this on rustc 1.99: no warning at the use site.
  • Limitation: a type alias can't build a tuple struct or match on one. So sd_jwt_vc::StatusType(3) no longer compiles; status_list::StatusType(3) and sd_jwt_vc::StatusType::INVALID still do.
• Other surfaces:
  • The utoipa schema of StatusType moves to status-list.
  • prelude::credentials now exports Status, StatusList and StatusListToken from status_list, behind status-list.

Docs

• docs/DESIGN.md: the upper-layer list, the module tree, the feature table, the vc and sd_jwt_vc sections, and a new status_list section.
• docs/FEATURES.md: a new status_list section with the moved rows (their feature column is now status-list), the renamed variant, a ✅ row for Move the Token Status List out of sd_jwt_vc #132, and the specification table.
• AGENTS.md: status_list added to the upper-layer list in the ground rules.
• README.md and the crate docs describe the new feature.

Tests

• The status list tests pass with only their import paths changed (CredentialStatus::SdJwt becomes StatusClaim).
• vc,status-list without sd-jwt: the status_claim tests in tests/vc_validation.rs are now gated on status-list. A new CI step in the Features job runs them with --no-default-features --features vc,status-list,did-key,did-jwk. In that configuration a JWT credential's status claim reaches the StatusCheck as CredentialStatus::StatusClaim. The test without the feature is gated on not(status-list) and passes with vc alone.
• Deprecated paths: deprecated_sd_jwt_vc_paths_still_work (in tests/sd_jwt_vc.rs) uses every old path under #[expect(deprecated)]. It fails if an alias stops being deprecated or stops naming the same type.
• Layer boundary: --no-default-features --features did-key,software still pulls in neither chrono nor miniz_oxide.
• Local checks, all passing:
  • cargo fmt --check
  • clippy with all features and all targets, -D warnings
  • cargo hack clippy --each-feature -D warnings
  • rustdoc with -D warnings
  • cargo test --all-features
  • the lower-layer build and cargo tree check
  • cargo publish --dry-run
  • semver-checks, which reports only the intended variant rename
  • cargo check of the sd_jwt_vc_metadata fuzz target

Walkthrough

This change moves Token Status List types and checking into feature-gated status_list, adds status-list independently of sd-jwt, and routes JWT and SD-JWT status claims through CredentialStatus::StatusClaim. Deprecated sd_jwt_vc paths remain available for one release.

Changes: Token Status List support

Layer / File(s)	Summary
Feature and public module surface Cargo.toml, src/lib.rs, src/status_list/mod.rs, src/prelude.rs, src/sd_jwt_vc/mod.rs, src/sd_jwt_vc/validation.rs, src/jose/mod.rs, src/vc/jwt.rs, src/vc/mod.rs, src/openapi.rs, README.md, docs/DESIGN.md, docs/FEATURES.md, AGENTS.md, .github/workflows/qa.yml, tests/openapi.rs, tests/sd_jwt_vc.rs, fuzz/fuzz_targets/sd_jwt_vc_metadata.rs	The new status-list feature enables status_list and is enabled by default. sd-jwt now implies status-list. The public module, exports, feature gates, documentation, schema tests, and feature-check workflow use the new module. Deprecated aliases retain the previous sd_jwt_vc paths.
Status list fetching and verification src/status_list/check.rs, src/status_list/mod.rs, src/sd_jwt_vc/credential.rs, src/sd_jwt_vc/credential_v2.rs, src/sd_jwt_vc/validation.rs, docs/DESIGN.md	StatusListCheck now lives in status_list. It fetches status-list tokens, follows up to three HTTPS redirects, resolves and verifies issuer keys, and evaluates status references. The former implementation is removed from SD-JWT validation, and SD-JWT credential code imports Status from the new module.
Shared credential status validation src/vc/validation/*, src/vc/validation/presentation.rs, src/sd_jwt_vc/validation.rs, tests/vc_validation.rs, tests/sd_jwt_validation.rs, tests/sd_jwt_v2.rs, docs/DESIGN.md, docs/FEATURES.md	CredentialStatus::StatusClaim replaces CredentialStatus::SdJwt for JWT and SD-JWT status claims. Parsing and checking use the status-list feature. The affected validation tests and documentation use the shared status variant.

Merge Risk: Low · up to cefc0

The change is mergeable with a bounded testing gap: CI will not catch a regression in strict rejection of status claims when status-list is disabled.

Explanation

The PR addresses active issue #132. It adds the upper-layer status_list module and the status-list feature with vc and miniz_oxide. It makes sd-jwt imply status-list and retain getrandom. It moves StatusListCheck behind did-web. It renames CredentialStatus::SdJwt to CredentialStatus::StatusClaim and validates JWT status claims without sd-jwt. Deprecated sd_jwt_vc paths, the utoipa schema, documentation, feature tests, compatibility tests, and the layer-boundary check are included.

Full details: Out of Scope Changes check

Explanation

The changed source, tests, documentation, CI configuration, and fuzz-target imports support the module move, feature separation, API rename, compatibility paths, or required validation. No unrelated change is established by the reviewed summary or focused source inspection.

Full details: Docstring Coverage

Explanation

Docstring coverage is 51.43% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 35 functions across 20 files. (6 skipped: 6 unsupported.)

Write docstrings for the functions missing them to satisfy the coverage threshold.

Run the vc_validation test with status-list disabled in CI.

The features job runs vc_validation only with status-list enabled. The test job runs --all-features, which also enables status-list. cargo hack clippy --each-feature compiles the disabled configuration but runs no tests.

status_claim_without_status_list_feature in tests/vc_validation.rs is compiled only under not(feature = "status-list"). It checks that StatusPolicy::Strict refuses a status claim when no check can receive it. No CI step compiles this test, so a regression in the not(feature = "status-list") branches of src/vc/validation/mod.rs would not fail CI.

🧪 Proposed fix

       # The Token Status List without SD-JWT: the `status` claim of a JWT credential reaches the
       # `StatusCheck` with `vc` and `status-list` alone.
       - run: cargo test --no-default-features --features vc,status-list,did-key,did-jwk --locked --test vc_validation
+      # Without the Token Status List: a `status` claim cannot reach a check, so `Strict` refuses it.
+      - run: cargo test --no-default-features --features vc,did-key,did-jwk --locked --test vc_validation
