mrwulf b232265264 docs: estate-wide consistency pass (workflow audit, 36 findings, all verified before fixing)
Nine parallel readers audited every doc against measured ground truth; every
finding was re-verified against the file before any edit, and the sweep fixed
by PROPERTY, not by flag — wording the readers caught in one repo was hunted
in all siblings (the two-button README sentence existed in all four forks,
not the three flagged; likewise the cone-overclaim in TRUSTED-BASE item 1).

This repo: see the diff. Records were not rewritten; clarifications are
dated. Doc-only except where noted in the estate summary; every gated doc
change was followed by a green button run.

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; 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.
