Implementation Check

This report checks the current repository state against:

  • product/proof.md (PRD)
  • product/Clyra_DEV.md (shared development standards)

Status key:

  • PASS: implemented and validated in repo
  • PARTIAL: implemented in part; notable gaps remain
  • GAP: not implemented yet

Proof PRD Check

Functional requirements

ID Status Notes
FR1 Record creation PASS Deterministic record creation + validation in core/record + proof.NewRecord().
FR2 Type registry PASS Built-in registry + runtime custom type registration + proof types list/validate.
FR3 Hash chain PASS Append + verify + range verify + break-point reporting in core/chain and CLI.
FR4 Signing PASS Ed25519 + cosign signing/verification paths implemented for records/chains and bundle manifests, including cert/identity/issuer verify options and revocation-list verification.
FR5 Canonicalization PASS JSON/SQL/URL/text/prompt canonicalization plus digest metadata (algo_id, salt_id) and HMAC-SHA-256 helpers in core/canon.
FR6 Verification CLI PASS verify, inspect, chain verify, types, frameworks; bundle signature verification, custom type schema mapping, --explain, and exit code contract implemented.
FR7 Framework definitions PASS 10 frameworks in frameworks/ and core/framework/; list/show, schema validation, and deterministic evidence coverage evaluation implemented.
FR8 Go module API PASS Primary API surface exported from proof.go.
FR9 JSON schemas PASS Base + type schemas + chain/bundle/framework schemas in schemas/v1/.

Acceptance criteria

ID Status Notes
AC1 4-line integration PASS Library usage is minimal; tested through API tests.
AC2 Universal verify PASS Verifies records/chains/bundles/Gait pack and Gait signed JSON artifacts via one CLI surface.
AC3 Chain integrity PASS Detects tampering and identifies break index/record.
AC4 Cross-product chain PASS Mixed record types chain and verify correctly.
AC5 Offline guarantee PASS Core verification is offline-first; cosign path is explicitly local-binary based, no mandatory network dependency in CLI flow.
AC6 Schema validation PASS Invalid/missing fields rejected by schema and validation layers.
AC7 Custom type PASS Runtime custom type registration is supported through CLI/API (--custom-type-schema, RegisterCustomTypeSchema), and verification validates base + custom schema.
AC8 Framework PR only PASS Built-ins are YAML starter definitions and LoadFramework(path) supports runtime loading of custom YAML without code changes.
AC9 Sigstore parity PASS cosign key/cert verification paths cover records/chains and Gait proof_records.jsonl verification with Sigstore options.
AC10 Determinism proof PASS Deterministic vector assertions are enforced in tests with a dedicated cross-platform determinism workflow.
AC11 Gait backward compatibility PASS Native Gait pack + signed-JSON verification with key-id compatibility is covered, including committed compatibility fixtures in testdata/gait_compat/.
AC12 Exit code contract PASS Implemented and validated in unit + contract script.

Clyra_DEV Standards Check

Area Status Notes
Go toolchain/layout PASS Module + cmd/, core/, internal/ layout in place.
Lint/format baseline PASS gofmt, go vet, golangci config present.
Pre-commit hooks PASS .pre-commit-config.yaml added.
Testing tiers PASS Tiered scripts and workflows are present for unit/integration/e2e/acceptance/hardening/chaos/performance/soak/contract.
Coverage gates PASS Coverage gates enforce package-level >=85 for core/cmd stack (with narrow allowlist exceptions) and >=75 package baseline.
Main CI pipeline PASS PR and main workflows with lint/test/build/contract checks, plus deterministic vector checks in cross-platform CI.
Nightly pipelines PASS Nightly workflow includes hardening/chaos/soak/acceptance with cross-platform hardening matrix + performance job.
Release integrity PASS GoReleaser, checksums, SBOM, grype, cosign sign/verify, and provenance attestation are wired in release workflow.
Security scanning PASS CodeQL + gosec + govulncheck + release vulnerability scan are present in CI/release gates.
Determinism standards PASS Deterministic hashing/signing/contract validations and benchmark budget checks are integrated in gates.
Exit-code contract PASS Stable 0..8 contract implemented and tested.
Schema management PASS Versioned schemas and schema validation tests present.
Repo hygiene PASS build artifact ignore fixed; generated artifacts not tracked by default.

Remaining Work

  1. No blocking implementation gaps against the current PRD and Clyra_DEV baseline are open in this repo snapshot.
