Three synchronized faces of one log - transport orthogonal to trust:
- PUBLISHED GIT MIRROR: log-publish exports the public face (one file
per leaf so git history mirrors log history; the FULL STH history as
the witness channel; per-component attestations + receipts; the
provider public key; a standalone stdlib-only verify.py and customer
README). Live at github.com/saymrwulf/lean-transparency-log (genesis:
8 leaves incl. the honest failed-run entries, dogfood-signed head).
- ONLINE SERVICE (pacta_provider serve): read-only, zero-dependency
HTTP with CT-style endpoints under a base path for
zkdefi.org/lean-transparency-log - /v1/sth, /v1/sth-history,
/v1/sth-consistency?first=N, /v1/proof, /v1/attestation, /v1/entries,
/v1/metadata, /healthz - plus self-contained customer documentation
at /docs (current state, attested components, API, the verify-
without-trusting-this-site path, and the means/does-NOT-mean
boundary). The process never loads private keys: heads are signed
offline; a compromised server can withhold or replay (pinning +
freshness detect both) but never forge. STH history now recorded
append-only by the provider (with a backfill head signed for the
existing log).
- AGENT ONLINE CLIENT: pacta log-fetch (download evidence; explicitly
UNVERIFIED until receipt-verify runs - transport is not trust) and
pacta sth-refresh (fetch head, verify signature, advance the pin via
an online consistency proof from the pinned size; fail closed).
- WITNESSES: pacta witness-audit over a clone of the published mirror
recomputes every prefix root from the public leaves and checks every
historical head + signature - no consistency proofs needed when the
leaves are public. Tampering one published entry trips both the
leaf-hash check and the prefix-root check (tested). verify.py gives
customers the same audit with zero installation.
- DEPLOY.md: the complete server-session checklist for zkdefi.org -
reconstruct the servable log FROM the published mirror (the server
stays in witness trust-position), hardened systemd unit, nginx/Caddy
path routing, Forgejo mirror setup, the provider->world update
cycle, and remote smoke tests.
Validated end-to-end on the REAL log: all 10 endpoints, online-fetched
proof re-verified locally through the dogfood verifier with pinning,
online pin refresh, publish + witness audit green, tamper caught,
standalone verify.py green in the published clone. 54/54 tests.
