mrwulf 43d7f00930 site: the key section's heading now matches its content — two anchors, one required, one additive 
Operator-caught logical fallacy: the h2 said 'pin this key' (singular)
and the card said 'sole identity anchor' while the same section
presents a second, additive post-quantum key ('sole' + 'Second anchor'
in one breath). The heading is now plural with the hierarchy stated;
'sole' became 'required' in both places it appeared; and 'exactly three
files' now names the optional fourth (the additive PQ key). Root cause:
the SLH-DSA block was APPENDED to the section in August without
re-reading the section against its own heading — local edit, no
whole-unit re-read.

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 ~/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; heads are dual-sign capable with an additive SLH-DSA-SHA2-128s slot (proven verify path), and the ML-DSA/FIPS 204 slot stays honestly not_configured/unavailable — never silently filled. 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.
