All six originated from the author's own adversarial read-through: 1. SS9: retrievability decay — leaves whose pinned commits are no longer distributed (0-7 post-rewrite) decay to historical record. 2. SS4.3: why-a-tree — per-item signatures cannot evidence deletion, expose forks, or provide pinnable state; dishonesty-evidence, not scale, is the motivation. 3. SS1: curve/signature crate parenthetical (one implementation). 4. SS8: ~1,800s/fork corroborated by inter-leaf issued_at spacing (within-run gaps 29m35s-30m40s). 5. SS5.1: git commit ids are hardened SHA-1 — said before a referee says it. 6. App A box fidelity: logical-vs-canonical order declared; ellipsis markers inside cert objects and at attestation level (covers diagnostics + inner schema_version); '(14 more)' -> '(14 certificates elided)'. Visual inspection: all changed pages (1,5,6,13,15,16,17) plus spill pages 18-19 read with own eyes; p.19 is a light final page (App D table), accepted over spacing tricks. 106 tests green, accumulator untouched. Page-count refs updated (webdocs, llms.txt). 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.
