REAL EVIDENCE: guarded replay of all four repos, attested, logged, dogfooded The provider ran its full honest replay against the four verified repositories on this machine - every Lean compile and axiom audit routed through lean-guard (memory-capped, core-pinned, single-flight, ~30 min per fork) - and the results are now shipped under evidence/: - 16/16 certificates proven per fork, every axiom cone boundary-exact (the four apex tiers carry their fork's documented SHA-512/wire boundary axiom-for-axiom), each attestation pinned to the exact repo commit (dalek 8ded7bc, anza 673c15e, risc0 98a13a6, betrusted 81f614a) and Ed25519-signed. - All four appended to the persistent transparency log. The log holds EIGHT leaves: the first four are the initial run's attestations, which honestly recorded an AUDIT FAILURE (the two pacta bugs fixed in e87f0e8) - an append-only trust ledger keeps its bad day, and the fixed run's leaves sit beside it. - Every receipt re-verified through the FULL stack: dogfood verifier (backend verified-dalek-serial recorded), STH pin store, freshness policy. Receipts are freshly issued against the final tree (a stale mid-run receipt tripped the pin store's rollback defense exactly as designed; the rollback diagnostic now hints at idempotent re-issue). - The capstone consequence ran for real: pacta agent with trusted provider + signature via the proven path + required receipt + pin store + --require-verified-verifier built the R4-gated library capsule from ATTESTED evidence (no local Lean replay needed by the consuming agent). Docs and teaching updated against the real artifacts: evidence/README (inventory + re-verify instructions), README "Real Evidence" section, lecture 5 now re-derives 16/16 verdicts from the REAL dalek attestation (signature checked on the proven path, provider labels ignored), and lecture 6 verifies all four REAL receipts and walks a fresh pin store over them. Every changed notebook cell executed before commit. 49/49 tests green. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The provider eats its own dogfood: root signatures via the merkleized library The dogfood principle now runs in BOTH directions. Agents already verified signatures through the proven dalek path; now the provider SIGNS with it too, and proves to itself that the signing code is in its own log before every signature: - dogfood binary gains a `sign` mode (seed over stdin, never argv; ed25519_dalek::SigningKey from the same pinned merkleized workspace). Honesty ledger unchanged: the library's VERIFY path is certificate-covered; its signing path is declared trusted base - but it is the ATTESTED artifact, not an un-attested third implementation. - sign_payload_ed25519_detailed: signing dispatch mirroring the verify dispatch; the backend that actually signed is recorded in every attestation signature block and STH. - THE SELF-REFERENTIAL CHECK: before signing any tree head, the provider runs the SAME Merkle inclusion verification an agent runs - against the very tree it is about to sign - for the newest leaf attesting the signing library itself, and embeds the result in the signature block: signing_provenance: signing_backend: verified-dalek-serial signing_library_component: dalek-ed25519-verified signing_library_source_commit: aa0f6ab... self_inclusion: verified signing_library_leaf_index: 4 signing_library_certificates_proven: 16/16 A root signature that names the leaf vouching for the code that produced it. First-append chicken-and-egg is handled honestly (self_inclusion: library_not_in_log). - Evidence refreshed: all four receipts re-issued under dogfood-signed STHs; the full agent verify loop re-run green. 50/50 tests (new signing roundtrip test, skip-safe where unbuilt).
