Release notes

Unreleased

0.15.0

• Registry Notary now requires every configured CEL worker to complete one bounded protocol probe and remain live before listener binding or readiness. Worker startup uses one 10-second wall-clock bound for the complete concurrent batch, evaluations retain their independent 2-second default, and failed evaluations return without waiting for background replacement startup. Healthy members of a mixed replacement batch are retained while initial activation remains all-or-nothing. Startup failures use the value-free notary.cel.worker_unavailable category.

0.13.0

• BREAKING: The closed Relay-result decoder rejects the retired provenance.consent member and accepts only the reduced registry.relay.consultation-result.v1 contract. Registry-backed issuance still requires compiler-pinned Relay evidence. Consent verification, policy enforcement, legal-basis handling, and authorization are unchanged.
• BREAKING: Deployment waivers replace reason with a required validated reference and optional validated summary. Strict configuration parsing rejects the retired field. Startup and readiness gates that were non-waivable remain non-waivable.

0.12.2

• Registry Notary has no new product features relative to v0.12.1. This release fixes forward from the incomplete v0.12.1 publication with a canonical reproducible release-build path for the Notary binary, CEL worker, and runtime image.
• The single-use eSignet authorization-code exchange now uses short-lived DNS-pinned transport. Redirects and proxies remain denied, request timeouts remain bounded, and the non-idempotent token exchange is not transparently retried. Public routes and authentication contracts are unchanged.

0.12.1

• Registry Notary has no new product features relative to v0.12.0. The release reviews the three non-fixable Debian 13 libc6 findings and binds that time-bounded accepted risk to the ordered runtime root filesystem layer digest. Fixable, expired, mismatched, and unreviewed findings fail the image advisory gate.

0.12.0

• BREAKING: The 1.0 wallet facade supports only issuer-initiated pre-authorized code backed by a stored registry transaction. The former credential-offer and public nonce routes are removed, and the credential response has no next nonce. Start with /oid4vci/offer/start, complete the identity-provider callback, redeem the rendered offer at /oid4vci/token, and use its transaction-bound proof nonce. The identity provider’s authorization code is never a wallet grant.
• OID4VCI source tests now cover complete issuance and client verification for EdDSA and ES256 issuer keys with an EdDSA did:jwk holder. Metadata advertises the exact configured issuer algorithm and only the supported holder profile.
• tx_code remains enabled by default. A no-PIN wallet profile must opt out explicitly and use a pre-authorized-code TTL no longer than 300 seconds. The offer is bearer credential material until its single use, so operators must prevent disclosure and retain redemption rate limits.
• Source-free claims remain evaluation-only. OID4VCI issuance reloads the registry transaction and exact Relay-backed evaluation provenance before signer access.
• Status-bearing credentials are verified fail closed from the configured exact HTTPS status origin. The reserved top-level status claim cannot be selectively disclosable.
• External wallet, verifier, OIDF, EUDI, or HAIP evidence remains candidate-only until recorded against a frozen release artifact.
• Batch evaluation now has a fixed 100-member platform ceiling with lower operator limits and pre-side-effect batch.too_large rejection.
• Registry Notary publishes a generated Draft 2020-12 runtime configuration schema derived from the production deserialization graph.
• Maintained Notary runtime images now use Debian 13 distroless. Release checks enforce the expected base and vulnerability policy before publication.

0.11.0

• BREAKING: Direct and OID4VCI credential issuance now require a fresh, non-delegated stored evaluation with an exact compiler pin for every claim in each selected root’s registry-backed dependency closure and one normalized record per unique Relay execution. Source-free and delegated claims are evaluation-only and cannot be configured for credential issuance. Existing evaluations remain readable and renderable but must be re-evaluated before issuance. See the credential issuance trust-boundary migration.
• BREAKING: Configuration ${VAR} expansion now rejects environment variables that are unset or empty. ${VAR:-fallback} uses its fallback for either state, ${VAR:-} explicitly expands to empty, and ${VAR:?message} reports its message for either state. Whitespace-only values remain non-empty.
• Registry Notary now verifies the retained audit chain during activation and reports confirmed integrity failures as audit.chain.inconsistent on /ready without exposing audit contents. Stop the process and use registry-notary audit quarantine with the deployed configuration to retain the corrupt files and open a tamper-evident break segment. The single-writer lock prevents online recovery, and signed-bundle acceptance audit failures still prevent bundle persistence and serving.
• Presenting multiple primary credential channels now returns the generic auth.multiple_credentials failure before any candidate is parsed or validated. The result does not reveal whether either candidate was valid.
• Omitted claim formats now defaults to canonical claim-result JSON. Explicit empty, unknown, CCCEV-only, and SD-JWT evaluation-format lists fail configuration validation; SD-JWT remains a credential issuance format.
• Registry-backed Relay consultations may bind bounded string, boolean, and integer inputs from request.target.attributes.<stable-name>. These values remain caller-supplied request context and cannot satisfy authenticated target-identifier requirements for delegated subject access.
• The local registryctl Notary tutorial evaluates one registry-backed claim through an exact Relay compiler pin. It does not exercise issuance, a wallet, credential presentation, or OID4VCI interoperability.

0.10.0

• BREAKING: Notary now has one deployable correctness-state backend: typed, Notary-owned PostgreSQL configured under state. Redis and per-domain backend selectors are removed without compatibility aliases. Use explicit in_memory only for single-process local development.
• Operators install and verify the schema with registry-notary state install and registry-notary state doctor. Startup and readiness verify PostgreSQL version, writability, schema fingerprint, role boundaries, and fixed transaction functions before traffic is admitted.
• Replay, nonce, evaluation, idempotency, credential status, quota, and preauthorization decisions now survive restart and coordinate identical active-active instances. The operations guide covers PostgreSQL 16 through 18, backup and restore, stale-restore quarantine, upgrades, and the clean pre-1.0 cutover.
• Redeemed pre-authorized codes use stable replay identity bound to the verified Notary issuer, so sensitive-state key rotation and unrelated service configuration changes cannot reopen a live no-PIN code.
• BREAKING: Registry-backed evidence now uses only authenticated, compiler-pinned Registry Relay consultations. Notary no longer accepts direct registry connections, DCI/FHIR connectors, source adapter sidecars, source credentials, or transitional evidence modes.
• Notary independently validates the full Relay consultation semantics and contract_hash before serving and at readiness. Mismatched purpose, inputs, outcomes, outputs, provenance, runtime requirements, or hash fail before source access.
• Relay consultation outcomes and typed outputs remain distinct from Notary claims. One consultation may supply several direct and CEL claims; no_match is explicit, while ambiguity and failures abort the consultation group and never become claim values.
• Relay-only, self-attested Notary-only, and combined project deployments are modeled separately. A combined project has one logical Relay connection and Notary receives no registry destination or source credential.
• BREAKING: authentication has no mode selector, and auth.mode is rejected. API keys and OIDC may coexist for distinct service and citizen or wallet callers, but each request presents exactly one credential type. Static bearer tokens and OIDC remain mutually exclusive because both use Authorization: Bearer.
• Combined projects keep the Relay’s public catalog origin separate from the internal Notary connection URL. An explicitly enabled literal IP-loopback HTTP origin is allowed only for the paired Relay inside a shared network namespace; remote HTTP remains invalid and public origins still require HTTPS.
• Registry-backed claim rules now use consultation_output and consultation_matched with explicit consultation and output fields. The unreleased source-named rule forms are rejected without aliases.
• Claim provenance moves atomically to registry-notary-claim-provenance/v2, exposing only relay_consultation_count; audit records use the same terminology.
• Federation configuration and signed results use evaluation and claim-result terminology: configure evaluation_scopes and max_claim_result_age_seconds, and consume claim_result_issued_at plus federation.stale_claim_result. Federation profiles remain source-free in this version, and Relay-backed federation remains deferred pending cross-service audit correlation.
• Release distributions include the standalone Linux amd64 registry-notary-cel-worker. CEL-enabled binary installations must place it beside registry-notary under that exact name. The Notary image includes the same isolated worker and cel.worker_memory_bytes remains the bounded operator control.
• The retired sidecar container, listener inventory, direct-source demo configurations, OpenFn caller demo, and direct DCI performance harness are removed.

0.9.0

• Production and evidence-grade deployments now fail closed until signer custody is explicitly approved for credential, access-token, and federation signing roles. /ready exposes typed, non-secret custody facts, while detailed deployment findings remain on authenticated operator surfaces. Review each role’s custody and retain the evidence before setting deployment.evidence.signer_custody_approved: true; the attestation is not a gate bypass.
• BREAKING: deployment.profile is required and must be one of local, hosted_lab, production, or evidence_grade. Notary refuses startup when it is absent instead of inferring a profile.
• BREAKING: claim configuration is validated at load time. Duplicate claim ids, invalid default disclosure modes, and rules referring to undeclared source bindings must be corrected before Notary starts.
• BREAKING: the TUF-era /admin/v1/config/verify, /admin/v1/config/dry-run, and /admin/v1/config/apply endpoints are removed, as is the CLI config apply-bundle command. First run registryctl bundle verify for stateless signature and binding verification, then place the signed Registry Config Bundle v1 on the Notary node. For a genuinely absent, version-specific antirollback state path, start Notary with --initialize-state; that boot verifies the bundle and initializes state. Notary’s read-only config verify-bundle command remains, but it requires accepted state to exist, so use it only for later candidate validation and restarts. Replace retired TUF-era fields inside config_trust with current Config Bundle v1 trust fields because strict parsing rejects the old schema. Hot apply is not supported. Back up the durable config_trust.antirollback_state_path state and keep release-specific restore sets. Restore the state belonging to the release during rollback; never delete or reinitialize it to force an older bundle to load.
• BREAKING: source-adapter sidecar configuration now rejects unknown keys. Remove misspelled, retired, or wrapper-only fields before upgrading.
• Evidence-grade deployments using audit shipping must configure a fresh acknowledgement cursor. Local-only file retention is a hard gate and cannot be waived.
• Federation denials after request verification now preserve available redacted peer, source-scope, profile, purpose, JTI, claim, and subject context in audit records, including response-signing failures.
• Added per-principal machine evaluation quotas and live audit-shipping health in readiness, posture, and doctor output.

0.8.4

• BREAKING: Static API-key and bearer-token config no longer accepts fingerprint.commitment. Remove that field from Notary YAML. Keep fingerprint.provider with fingerprint.name or fingerprint.path; the referenced value must contain sha256:<64 lowercase hex chars>.
• Static credential rotation is now either a secret-plane update plus restart, or a signed config bundle change to a new immutable or versioned fingerprint reference, placed on the node and activated by restart. OIDC remains the preferred production model for citizen and wallet flows.

0.6.2

• Fixed federated evaluation policy-context handling so federation profiles can satisfy source matching gates for legal basis, consent, jurisdiction, and assurance without being treated as scoped transaction authorization details.
• Restores delegated federation evaluations that use governed source-policy gates.

0.6.1

• Fixed static credential policy-context compatibility for source matching: static credentials can again carry configured legal basis, consent, jurisdiction, and assurance context for PDP gates without being treated as exact per-transaction authorization scopes.
• Kept OIDC/RAR authorization details fail-closed unless transaction scope fields are present.

0.6.0

• Added delegated self-attestation support with explicit requester-side target binding, canonicalized delegated targets, and claim-lookup validation.
• Bound delegated authorization details to the requested identifier type so a delegated attestation cannot drift across supported identity forms.
• Hardened authorization-details handling before batch prefetch, credential issuance, render, evaluate, pre-authorization, status-list, and data-route audit paths.
• Added cache compare-and-set support for credential status transitions and status-list signing so concurrent updates fail closed.
• Refreshed the Registry Platform pin to the beta-4 platform release.

0.3.0

• Added citizen self-attestation flows, including bearer-token subject binding, rate limiting, denial audit metadata, and SD-JWT VC issuance.
• Added OpenID4VCI issuer primitives and HTTP routes for credential issuer metadata, SD-JWT VC Type Metadata at configured vct URLs, credential offers, nonce creation, and credential issuance.
• Added the source adapter sidecar path for private source reads, including built-in http_json, http_flow, and fhir engines, source concurrency controls, target rate limits, Retry-After backoff handling, bounded result caching, and DHIS2 canary smoke scripts.
• Kept CEL out of default builds while adding an opt-in CEL production image profile with hardened worker execution, startup expression preflight, declared result-type enforcement, and policy-hash worker protocol checks.
• Added named SD-JWT VC signing keys under evidence.signing_keys, including local JWK signing, publish-only rotation keys with optional bounded publication windows, disabled keys, and optional PKCS#11-backed Ed25519 signing.
• Historical note: 0.3.0 introduced the first governed config prototype with signed TUF bundles, config verify-bundle, config apply-bundle, and config_trust. Current releases use Registry Config Bundle v1 instead: a local directory with manifest.json, manifest.sig.json, and config/.... Before a first boot, registryctl bundle verify checks signatures and bindings without product antirollback state. The first boot with genuinely absent state uses --initialize-state; after state exists, the read-only product config verify-bundle command supports later candidate validation and restarts. There is no current apply-bundle command and no hot apply.
• Added server.admin_listener to split admin and public HTTP topology. The dedicated mode serves /admin/v1/* and /metrics on a separate admin bind, shared_with_public serves them on the public listener, and disabled drops the admin listener entirely. Governed config_trust requires dedicated.
• Changed the default server.admin_listener.mode from shared_with_public to disabled; local deployments that intentionally need the old shared topology must set server.admin_listener.mode: shared_with_public explicitly.
• Added bounded HTTP serve defaults: server.request_timeout: 30s, server.request_body_timeout: 10s, server.http1_header_read_timeout: 10s, and server.max_connections: 1024. The source adapter sidecar mirrors the same limits with millisecond-suffixed config keys.
• Changed auth.api_keys[] and auth.bearer_tokens[] to a committed fingerprint reference (provider, name, commitment) in place of hash_env, so a signed config bundle can govern caller-credential rotation after restart.
• Renamed OIDC config fields to the shared Registry service convention: auth.oidc.jwks_url, auth.oidc.leeway, and auth.oidc.allowed_token_types. Legacy aliases fail config load with an error naming the replacement. auth.oidc.leeway now uses humantime strings such as 30s; self-attestation token_policy.max_clock_leeway_seconds still bounds the resolved duration.
• Removed server.cors.allow_credentials; Registry Notary now always disables credentialed CORS on the operator-configured server CORS layer. Remove the field from config rather than setting it to false.
• Renamed audit.max_size_bytes to audit.max_size_mb and aligned the default active-file rotation to 100 MB with 14 retained files.
• Added REGISTRY_NOTARY_LOG_FORMAT=text|json; the default log filter is plain info.
• Product binaries and container images now compile the PKCS#11 provider by default, while vendor modules, token state, labels, and PIN handling remain operator-supplied runtime configuration.
• Hardened SD-JWT VC conformance for dc+sd-jwt, holder binding, proof validation, and OpenAPI documentation.
• Replaced fake Problem Details type URLs with https://id.registrystack.org/problems/registry-notary/....
• Changed self-attestation subject-binding hashes to keyed HMAC values and stopped recording raw query strings in request spans or audit paths.
• Known limitations: this release is dc+sd-jwt only, does not serve /.well-known/jwt-vc-issuer, does not implement PKCS#12 issuer keys, does not certify a vendor HSM, and leaves retention/erasure workflows to the operator.

0.2.1

• Added evidence.source_connections[].allow_insecure_private_network for Docker Compose and private-network demos that need HTTP source registries. The escape hatch is opt-in, keeps cloud metadata endpoints blocked, and leaves the strict HTTPS policy as the default.

0.2.0 (rename)

• Renamed: evidence-server → registry-notary. No backward compatibility; no aliases.
  • Crates: evidence-core → registry-notary-core, evidence-server → registry-notary-server, evidence-server-bin → registry-notary-bin.
  • Binary: evidence-server → registry-notary.
  • Media type: application/vnd.evidence-server.claim-result+json → application/vnd.registry-notary.claim-result+json.
  • Default audience: "evidence-server" → "registry-notary".
  • Cargo feature: evidence-server-cel → registry-notary-cel.
  • Project-labeled env vars: EVIDENCE_SERVER_API_KEY, EVIDENCE_SERVER_BEARER_TOKEN, EVIDENCE_SERVER_ISSUER_JWK → REGISTRY_NOTARY_API_KEY_HASH, REGISTRY_NOTARY_BEARER_TOKEN_HASH, REGISTRY_NOTARY_ISSUER_JWK. The renamed auth variables hold sha256:<64 hex> fingerprints, not plaintext tokens.
  • Demo config: demo/config/evidence-server.yaml → demo/config/registry-notary.yaml.

0.1.0

• Initial Evidence Server repository cut from registry_relay.
• Preserves evidence-core and evidence-server crate behavior as an independent Cargo workspace.
• Adds evidence-server-bin for standalone config loading, binding, tracing, shutdown, fail-closed API key and bearer-token auth, and redacted audit event output.
• Adds HTTP Registry Data API and DCI source connectors so claim evaluation can use external source registries without linking Registry Relay.
• Keeps CEL enabled by default through cel-mapper-core, pinned to PublicSchema/cel-mapping tag cel-mapper-core-v0.1.0.
• Adds a cargo run -p evidence-server-bin -- openapi command for owned Evidence Server OpenAPI output.

Known non-goals for this cut:

• 0.1.0 does not include OIDC/JWKS discovery; the standalone binary supports API keys and static bearer tokens.
