# { "Depends": "py-genlayer:1jb45aa8ynh2a9c9xn3b7qqh8sm5q93hwfp7jqmwsfhh8jpz09h6" } """ PacketProof — on-chain release-metadata attestation for npm and PyPI packages. CONCEPT ------- Before a package is published, the maintainer locks a release intent on-chain: package name, registry ecosystem (npm/pypi), version, and the expected source commit SHA on github.com. After publication the maintainer submits a snapshot of the release. The contract independently fetches the registry's own record and the commit's raw patch (no caller-supplied URLs; both fetch targets are derived from the locked identifiers), and validators independently judge three rules: changelog_present, changelog_honest and version_consistent. The verdict routes deterministically to VERIFIED, INCONCLUSIVE or BLOCKED. WHAT A CERTIFIED RELEASE PROVES (and what it does not) ------------------------------------------------------ Proves, at the time of attestation: 1. the registry record for the locked name+version echoes that name+version; 2. every dist hash the maintainer committed to appears in that registry record; 3. the GitHub patch for the locked commit SHA was fetched and echoes that SHA; 4. validators independently agreed the changelog is present, honestly describes that patch, and that the version bump is consistent with it; 5. no admitted challenge, re-judged by the validators with the challenger's evidence in the prompt, overturned the result before the review window closed. Does NOT prove: that the published package bytes were built from the commit. The contract never downloads or hashes the tarball/wheel and does not compare source to artifact; the dist hashes are matched against the registry's own metadata, not recomputed. Commits that reach the contract only through a fork of the named repository are not distinguished from the repository's own. Patches longer than MAX_DIFF_CHARS cannot be judged whole and route to INCONCLUSIVE. WHY MULTI-VALIDATOR CONSENSUS ----------------------------- The changelog-versus-patch judgment is a subjective call a maintainer benefits from getting wrong. Each validator re-fetches the registry record and the patch itself and re-derives every per-rule status; agreement is exact on the statuses and on every fetched-evidence digest. SHAPE: Single-party attestation with bounded challenge window. No staking. The consequence is a permanent public attestation record. STATE MACHINE ------------- DRAFT → COMMIT_LOCKED → VERIFIED | INCONCLUSIVE | BLOCKED → CERTIFIED - DRAFT: intent registered; release not yet submitted for verification. - COMMIT_LOCKED: release submitted; awaiting attestation call. - VERIFIED: all checks passed; review window open for challenge. - CHALLENGED: a challenge is open during the review window. - INCONCLUSIVE: evidence unavailable, malformed, or conflicting. - BLOCKED: at least one critical rule is VIOLATED. - CERTIFIED: survived review window with no successful challenge; terminal. - REVOKED: owner revoked before CERTIFIED; terminal. VERDICT SHAPE: Graded per-rule findings with closed-enum statuses. Every verdict value is reachable by a distinct leader_fn branch. EVIDENCE BINDING (Rules 0.7 + 0.8) ------------------------------------- Registry fetch URL is derived deterministically: npm: https://registry.npmjs.org/{name}/{version} pypi: https://pypi.org/pypi/{name}/{version}/json Caller never supplies the fetch URL. The fetched record is checked for the presence of the locked package name and version before it influences the verdict (Rule 0.8 echo check). Commit fetch target is derived from the locked VCS repo + commit SHA — never a caller-supplied URL. NONDET PATTERN -------------- All leader/validator pairs follow sections 3–6 of the GenLayer Agent Playbook: 1. run_nondet_unsafe positional, never keyword args. 2. validator_fn checks isinstance(leaders_res, gl.vm.Return) first, reads .calldata — never json.loads on it. 3. No .send(); no value transfers (no staking in this contract). 4. copy_to_memory() before every nondet call. 5. Constants at module level only; class-body attributes are storage. 6. leader_fn/validator_fn nested inside @gl.public.write; zero self. _verify_challenge_evidence is inlined into open_challenge (Bug B fix). 7. Per-record arrays stored as delimiter-joined str. BUG FIX RECORD (steward review, Oct 2026) ----------------------------------------- S1: reassess_challenge re-ran attestation without the admitted challenge evidence in the prompt, so a challenge could never change a verdict. The evidence text is now in the prompt, and a fourth rule (challenge_evidence_addressed) is added for CHALLENGE runs so validators must commit to a status on it; INCONSISTENT routes to BLOCKED. S2: an unavailable commit fetch was passed to the model as a marker string and could still produce VERIFIED; the HTML commit-page fallback could be judged as a diff. Now: raw .patch only, must echo the locked SHA, must fit MAX_DIFF_CHARS; otherwise INCONCLUSIVE (evidence_code COMMIT_*), never VERIFIED. S3: claims narrowed to what the contract proves (see above); source-to-artifact verification is not implemented. All committed dist hashes (not any one) must match the registry record. S4: repository_url restricted to github.com//, the one provider whose commit endpoint is implemented. GitLab and Bitbucket are rejected. BUG FIX RECORD (second audit) ----------------------------- E1: gl.storage.copy_to_memory() was called on plain dicts parsed from JSON strings; the SDK asserts on non-storage values, so submit_snapshot, attest_release and open_challenge reverted. Now detached JSON copies. E2: _now() used datetime.now(); replaced by the integer-only parser of gl.message_raw["datetime"]. E3: ordinary-retry limit was never enforced (fresh generation each attempt); now counted per package version. E4: list_packages was rebuilt from a 300-slot event ring and dropped older packages; now backed by package_index. E6: dist-hash matching accepted only 'key:value' strings, but the UI/docs tell maintainers to paste the bare registry value; both forms now match. E5: a registry reply that is valid JSON but not an object crashed leader_fn. BUG FIX RECORD (first audit, Oct 2026) ---------------------------------- Bug A: _fetch_json and _fetch_text defined at module level but contain gl.nondet.web.get(). Fixed: both are now nested inside each leader_fn that needs them. Module level only has pure helpers (_dumps, _digest, _sanitize, etc.) with zero gl.nondet.* calls. Bug B: _verify_challenge_evidence was a plain instance method calling run_nondet_unsafe via self. Fixed: inlined into open_challenge body; leader_fn/validator_fn are local closures with zero self. references. Bug C: _run_attestation dead branch (ternary overwritten by if block). Fixed: single clean if/else for gen assignment. Bug D: All views returned raw dict/list. Fixed: every view now returns json.dumps via _dumps() — the str return type is enforced by GenVM.
