CIRISPersist
One embeddable Rust crate behind every stateful surface a CIRIS federation node needs — the signed reasoning-trace log, the hash-chained audit log, the memory graph, time-series telemetry, secrets-at-rest, federation trust state, and the CEG §19 holonomic / forever-memory substrate (fountain content, WholenessWitness, aggregation tiers). Postgres or SQLite; in-process via PyO3 or over HTTP.
Current: v8.5.0 · CIRISVerify pin v5.10.0 · CEG §19 / §19.7 (1.0).
What it is
CIRISPersist is the lowest stateful substrate above
CIRISVerify. An agent or lens node
links it as a library — pip install ciris-persist — and gets every storage
surface it needs from one versioned API instead of ~11 hand-rolled services.
The backend is chosen at Engine construction by DSN scheme
(postgres://… or sqlite://…); every method works on both.
Substrates
| Substrate | Backs |
|---|---|
| trace ingest | signed reasoning-trace event log + LLM-call log |
cirisaudit |
hash-chained, per-tenant signed audit log (RFC 6962 Merkle) |
cirisgraph |
memory nodes + edges — absorbs MemoryService / ConfigService |
telemetry |
metric writes + TSDB rollup |
secrets |
federated SecretsService — AES-256-GCM at rest, hardware-backed master key |
cirisnode |
CIRISNodeCore federation-consensus substrate |
fountain |
fountain-coded content primitive — signed manifest + N+K opaque symbols, tier eviction, authenticated partial reads (CEG §19.3) |
wholeness_witness |
§19.1 WholenessWitness corpus — divergence detector that routes to the existing quorum-merge (CEG §19) |
content_aggregation |
§19.7 forever-memory aggregation tier — N→1 composites, opaque aggregation_meta, descent-integrity (CEG §19.7) |
sequence / occurrence |
atomic per-identity counters + endpoint-liveness registry |
| lens substrates | tasks, thoughts, correlations, tickets, deferral reports, WA certs, … |
Honest read
- Postgres + SQLite at 100% parity. Every PyO3 method works on both backends — including the observability read API and the lens-derived schemas — so sovereign-mode (Pi / iOS) deployments are not second-class.
- In-process cohabitation.
Engineis a process-singleton: a CIRIS 3.0 process hosting the agent + NodeCore + LensCore shares one runtime, one pool, one identity — see docs/COHABITATION.md. The publicffi::pyo3::register(py, m)hook (#231) lets a host wheel re-export the whole persist surface into its own module — one.so, one PyO3 type registry (CIRISServer one-wheel). - Hardware-backed secrets. The secrets master key is derived — via CIRISVerify — from a seed sealed by the platform TPM / Keystore / Secure Enclave where one exists, with an honest software fallback where it does not.
- Crypto goes through CIRISVerify. Persist never rolls its own — signing,
verification, and key derivation route through
ciris-verify-core/ciris-keyring(pinned v6.0.0, all six crates flipped in lockstep). The §19 holonomic gates (verify_witness,compare_witnesses,verify_aggregation_meta,verify_member_commitment,ejection_verdict,compute_merkle_root) are all verify-core calls — persist never re-rolls Merkle / preimage / signature logic. - Holonomic / forever-memory substrate (CEG §19 / §19.7, 1.0). Persist
is the store + WholenessWitness-corpus owner + the divergence→quorum-merge
router. A withdrawn
content_idis hard-deleted regardless of rarity (revocation overrides rarity); a witness equivocation is retained and flaggedhard_case:witness_equivocation, never reconciled. Memory fades along one pressure-driven descent but cannot be falsified — the signed envelope/manifest is the incorruptible anchor and partials stay authenticated against the signed per-symbol hashes. - Constitution alignment (0.1.5). v9.0.0 binds persist to the substrate
clauses of the CIRIS Constitution
0.1.5.
Federation-tier ingest is PQC-mandatory — every
tier = federationwrite is hybrid-verified (Ed25519 + ML-DSA-65,Strict) at the admission gate, local-tier exempt (CC 5.3.2.4.3.1; BREAKING — classical-only federation rows are non-conformant). Anode-only key'sdelegates_tomay carry onlyinfra:*scopes, neveragency:*— "infrastructure must not have agency" enforced cryptographically (CC 4.4.3.4.3 / CC 1.13.5). Non-infra community membership for a node/agent key requires owner-binding to a human (CC 3.2 / CC 3.4.7.1), and community content is sealed under a per-community DEK rotated zero-window on member removal (CC 4.4.3.2.1 / 4.4.3.2.2,wrap_algorithm: v2only). Privacy stays bounded — cohort scope hides content, not contact (CC 1.13.3.1; see MISSION.md §1.9). See docs/THREAT_MODEL.md §3.15 (AV-67..AV-72). - 1+4 lockdown. Persist adds zero structural primitives (CC 1.7 —
the federation's one workhorse attestation primitive + four structural
composers). Every substrate above rides
scores+ asubject_kind+ the four composers (delegates_to/supersedes/withdraws/recants) — the constitution-alignment gates are admission logic over the existingfederation_keys/ attestation surface, not new wire shapes. - Deliberately not: no embedded graph DB engine (Postgres / SQLite recursive CTEs instead); not a daemon (a library, not a service); horizontal sharding is out of scope.
Performance & SOTA
Measured by the in-repo criterion suite (benches/ — eleven harnesses run per
commit and published to the
trend dashboard).
Representative
current numbers:
- AES-256-GCM (secrets-at-rest) — ~9.5 GiB/s, via CIRISVerify v2.8.0.
- Analytics — V042 covering indexes turn the scoring
ReadEnginequeries into index-only scans;cross_agent_divergence~−42% vs. a raw table scan. next_sequence— a durable, async-safe atomic counter increment ~10 µs (the SQLite UPSERT itself ~2 µs; the rest is the async wrapper).- Cold start — open + full migration run ~12 ms.
| Capability | SOTA peers | CIRISPersist |
|---|---|---|
| Embedded persistence | ORMs — sqlx, Diesel; per-service DBs | one API, Postgres + SQLite at 100% parity — at parity |
| Audit log | Trillian, Rekor, AWS QLDB | RFC 6962 Merkle + post-quantum-signed tree heads — ahead of typical |
| Crypto-at-rest | ring, OpenSSL (~3–6 GiB/s AES-GCM) | ~9.5 GiB/s AES-256-GCM via CIRISVerify — ahead |
| Post-quantum | mostly classical | hybrid Ed25519 + ML-DSA-65 throughout; Full-mode traces + fountain manifests + aggregation meta reject classical-only at ingest (HNDL hard cut, CEG §10.1.5.1.1) — ahead |
| Analytics | DuckDB, ClickHouse (columnar) | row store + query-shaped covering indexes ("poor-man's column store") — at parity for the fixed query set; ~2–5× behind a columnar engine on raw ad-hoc scan |
| Horizontal scale | sharded DB services | a library, not a service — behind (deployment shape, not algorithm) |
Ahead on post-quantum crypto and the Merkle audit log; at parity on embedded persistence and on analytics for its closed query set; the one real "behind" — horizontal scale — is a library-vs-service choice, not an algorithm gap.

License
AGPL-3.0-or-later. The persistence path is auditable line-by-line by design: closed-source forks are forbidden, which makes the federation primitive's audit story structurally enforceable, not merely socially expected.
