Provide a deterministic cognition ledger that uses power_house for verification and optionally pent_house for resonance behavior. Keep the code standard-library only beyond those two crates.
- Same
(label, seed)yields identical shard bytes. - Core tests cover ≥80% of the engine and ledger logic.
- Quickstart works copy‑paste with no external services.
- Mint shard from
(label, seed)→ checksum and energy. - Verify shard by recomputing and comparing checksums.
- Append-only ledger with a cumulative digest.
- Minimal operations endpoints:
/healthzand/metrics.
- Input validation on labels and seeds.
- No secrets in the repository.
- Basic logging as line‑delimited JSON to stdout.
- Rollback by restoring a previous ledger file.
