Operator order: coherent, precise, accessible — an undergraduate CS student must understand what the service provides, how to benefit, and what to DO from each trust angle. The page now opens in plain terms (what happened, why this site exists), keeps the precise one-sentence as the second voice, and replaces 'Three ways to use it' with the FIVE-rung trust ladder: (1) witness — hold the history honest, one minute; (2) trust the reports, bind the operator — milliseconds; (3) accept observations, reject judgment — re-derive verdicts from recorded cones against your own card, the rung most people miss; (4) replay the proofs yourself — ~30 min/library; (5) rebuild the whole path — weeks, floor named (kernel/extractors/compiler; no rung 6). Split-view comparison stated as orthogonal to all rungs. The API box is demoted to 'For your tooling — the raw API' at the bottom with its reason for existing stated (machine consumers; pacta builds on it). All content guards keep their exact phrases; suite 154 green. |

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.
