ciris-persist 0.4.4

Unified Rust persistence for the CIRIS federation — signed events, time-series, runtime state.

CIRISPersist

Unified Rust persistence for the CIRIS federation — signed events, time-series, runtime state.

Status: 0.1.0 — Phase 1 lens-ready. The Phase 1 ingest pipeline is end-to-end testable and lands the lens cutover from accord_traces (per-thought row collapse) to trace_events + trace_llm_calls (per-broadcast event log) per FSD §3.5. Phase 2 (agent's audit_log + service_correlations) and Phase 3 (runtime state + memory graph + governance) reuse the same Backend trait without restructuring.

This crate is the operational form of the architectural collapse the Proof-of-Benefit Federation FSD §3.1 specifies: lens-side ingest+verify+scrub+store and agent-side audit-chain+TSDB+runtime persistence are the same job at different scales. We carve the work into three phases — each independently shippable, each gated on a measured operational reason — with a single crate API designed from Phase 1 to support all three without rewrites.

Reading order

If you have 5 minutes: MISSION.md and FSD/CIRIS_PERSIST.md §1, §2, §3.6.

If you have 20 minutes: the FSD top-to-bottom plus FSD/PLATFORM_ARCHITECTURE.md.

If you are integrating with the lens (Phase 1): the FSD §3 in full plus context/TRACE_WIRE_FORMAT.md and the tests/wire_format_fixtures.rs integration suite (real signed traces from agent release/2.7.8).

If you are planning Phase 2/3: the FSD §4–§5 plus context/agent_persistence_README.md.

Phases

Phase	Surface	Trigger
1 (0.1.0 — shipping)	Lens trace ingest: trace_events, trace_llm_calls, accord_public_keys. Ed25519 verify, PII scrub, batch persist via TimescaleDB hypertables.	Now.
2	Agent signed-events + TSDB: audit_log, audit_roots, audit_signing_keys, service_correlations. PyO3 from inside the agent process.	When peer-to-peer trace replication is on the roadmap.
3	Agent runtime state, memory graph, governance: tasks, thoughts, graph_nodes, graph_edges, tickets, dsar_*, deferral_*, wa_cert, feedback_mappings, consolidation_locks, queue_status.	When ≥30 days of Phase 2 stability + a named operational reason.

Out of scope: CIRISRegistry, CIRISPortal — external services with their own DBs and replication strategies.

Quickstart — lens FastAPI integration

import ciris_persist as cp

engine = cp.Engine(dsn="postgres://lens:lens@localhost:5432/cirislens")
engine.register_public_key(
    signature_key_id="agent-8a0b70302aae",
    public_key_b64="<base64-encoded 32-byte Ed25519 verifying key>",
    agent_id_hash="8a0b70302aaeb401...",
)

# In FastAPI handler:
summary = engine.receive_and_persist(request_body_bytes)
# → {"envelopes_processed": 1, "trace_events_inserted": 12, ...}

Quickstart — Rust standalone server (Phase 1.1 deployment shape)

use std::sync::Arc;
use ciris_persist::{
    server, spawn_persister, Journal,
    scrub::NullScrubber,
    store::PostgresBackend,
    verify::PythonJsonDumpsCanonicalizer,
};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let backend = Arc::new(PostgresBackend::connect(&std::env::var("CIRIS_DB_URL")?).await?);
    backend.run_migrations().await?;

    let journal = Arc::new(Journal::open("/var/lib/cirislens/journal.redb")?);
    let handle = spawn_persister(
        ciris_persist::DEFAULT_QUEUE_DEPTH,
        backend,
        Arc::new(PythonJsonDumpsCanonicalizer),
        Arc::new(NullScrubber),
        journal.clone(),
    );

    let app = server::router(server::AppState { handle, journal });
    let listener = tokio::net::TcpListener::bind("0.0.0.0:8080").await?;
    axum::serve(listener, app).await?;
    Ok(())
}

Mission Driven Development

Every component, every test, every PR cites against MISSION.md. The methodology is from ~/CIRISAgent/FSD/MISSION_DRIVEN_DEVELOPMENT.md. Three structural legs (LOGIC, SCHEMAS, PROTOCOLS) supporting one purposeful seat (MISSION = Accord Meta-Goal M-1).

Test coverage organized by mission category (MISSION.md §4):

Category	Coverage
Schema parity	Wire-format round-trips, real-fixture deserialization, dedup-key derivation
Verify rejection	Schema version, attempt_index sign, signature mismatch, unknown key, malformed sig, wrong key
Canonicalization parity	14 byte-exact fixtures vs python json.dumps; JCS-divergence test
Idempotency	Dedup tuple, repeat batches, intra-batch duplicates
Backpressure	Full queue → 429 + Retry-After
Power-cycle resilience	Journal append/replay survives reopen; halt-on-error preserves order
Backend parity	Memory impl conformance suite (postgres conformance gated on CI DSN)

License-locked mission preservation: anyone reasoning about whether a CIRIS-derived deployment preserves M-1 alignment can see and audit every line of the persistence path. Closed-source forks are forbidden by the license, which makes the federation primitive's audit story structurally enforceable, not merely socially expected.
