Socratic audit findings, all verified against artifacts: - 'zero lines between structurally identical forks' was FALSE: risc0 vs betrusted differ by 27 lines (all annotation, documenting the risc0 fork's black_box trusted-base entry). Corrected to the true number. - '~64 Lean files per fork' over-rounded anza's 58. Now '58-64'. - completeness parenthetical now states both hypotheses (a=-1 square, d non-square), not just d. - 'key published in two independent locations' was ASPIRATIONAL: the site served only a fingerprint. New /log-public-key endpoint serves the key bytes; docs-page artifact-1 row links both copies; test added. Verified exactly and kept: 215-line parser diff (FromBytesSpec), 121-line signature-glue diff (SigApexSpec), byte-identical x4 math files incl. the carry-telescope file, 11-axiom upstream boundary, 16 certs/leaf, 153-line mirror verifier, leaf fields (toolchain + machine_protection), all 17 refs.

PACTA Proof Check Provider
This nested project is a prototype third-party proof-checking service. It reuses host Lean/Aeneas infrastructure, runs portable PACTA replay/audit checks, and emits signed attestation certificates.
It does not modify anything outside this repository. It may read configured toolchains such as /Users/oho/GitClone/ClaudeCodeProjects/your-lean-project/aeneas-toolchain/env.sh.
It can also maintain a local transparency log. The log is an RFC 9162-style Merkle accumulator over signed attestations. It emits Signed Tree Heads with Ed25519 today and records an ML-DSA/FIPS 204 signature slot as unavailable unless a real backend is present. Agents that require both signatures must reject such receipts.
Commands
PYTHONPATH=src:provider/src python -m pacta_provider discover
PYTHONPATH=src:provider/src python -m pacta_provider init-key --key-dir provider/state/demo-provider
PYTHONPATH=src:provider/src python -m pacta_provider check \
--config examples/repos.yaml \
--repo-name dalek-ed25519-verified \
--repo repos/dalek-ed25519-verified \
--provider local-pacta-provider \
--private-key provider/state/demo-provider/provider.ed25519.key \
--public-key provider/state/demo-provider/provider.ed25519.pub \
--out provider/out/dalek.attestation.yaml
Transparency log:
PYTHONPATH=src:provider/src python -m pacta_provider log-init \
--log-dir provider/state/transparency-log \
--provider local-pacta-provider \
--public-key provider/state/demo-provider/provider.ed25519.pub
PYTHONPATH=src:provider/src python -m pacta_provider log-append \
--log-dir provider/state/transparency-log \
--attestation provider/out/dalek.attestation.yaml \
--private-key provider/state/demo-provider/provider.ed25519.key \
--public-key provider/state/demo-provider/provider.ed25519.pub \
--out provider/out/dalek.receipt.yaml
PYTHONPATH=src:provider/src python -m pacta_provider log-sth \
--log-dir provider/state/transparency-log \
--private-key provider/state/demo-provider/provider.ed25519.key \
--public-key provider/state/demo-provider/provider.ed25519.pub
The resulting certificate can be consumed by pacta with --attestation, --trust-attestation-provider, and --attestation-public-key.
The receipt can be consumed with --transparency-receipt, --transparency-log-public-key, and --require-transparency-receipt.
The private key must remain provider-side. Downstream agents only need the public key, the inclusion receipt, and a policy decision that the provider name/log key is trusted.
