- §5/N1: the '16/16 proven' pill was hardcoded — false for the accumulator (61 certs). Now computed proven/total from each component's newest leaf (forks show 16/16, accumulator 61/61). - §2: 'the only thing you take on trust' → 'sole cryptographic identity anchor; truth rests on each leaf's stated assumptions' (both the top card and the download table). - §3: 'the signature vouches for the code that produced it' → the signed tree CONTAINS an attestation of the reported signing source; execution provenance is reported, not proven; provenance fields are unsigned metadata. - §9: 'irrevocably part of the log every other customer sees' → this signed head commits it to THIS view; comparison exposes split views. - §4.4: witness 'never equivocated' → a retained view that can EXPOSE a conflicting head; one clone cannot prove no split view. - §10: 'the git hash is the content hash' → the commit identifies the committed git tree, not deps/toolchain/artifacts. - §6: live-site 'twelve-leaf deployment' blurb → 'live deployment'. Suite 115 green. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> |

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.
