ciris-server 0.5.75

The fabric node — the federation's headless cohabitation runtime (registry + lens [+ node] over one shared substrate), as the abi3 wheel CIRISAgent consumes. agent = fabric node + brain.

CIRISServer — the fabric node

The decentralized CEWP node/client. agent = fabric node + brain. CIRISServer is the federation's headless cohabitation runtime: the same composition of cores that folds into a CIRISAgent, packaged without a reasoning brain. Infrastructure must not have agency — so the fabric node attests, stores, observes, reaches consensus, and transports, but it does not reason, decide, or act.

It is the node software for CEWP — the decentralized network formed by CEG, the CIRIS Epistemic Grammar. Any operator can run one; no single instance is load-bearing.

Read MISSION.md first — the charter (why this exists, the separation-of-powers invariant, the apophatic bounds), written against the CIRIS Accord (M-1), the CEG §7.0.1 fabric-node discipline, and Mission Driven Development. The build plan + dependency GANTT live in FSD/SERVER_1.0_PLAN.md.

What it is

A thin composition crate — shipped as both the headless ciris-server binary and a PyO3 abi3 wheel that CIRISAgent (pure Python) links instead of composing the cores itself — linking the federation's cores as libraries over one shared substrate:

ciris-server (the fabric node)
  ├── ciris-registry-core   authority    — identity / license / revocation / steward attestation
  ├── ciris-lens-core       observation  — Coherence Ratchet / Capacity Score (validated, not adjudicated)
  ├── ciris-node-core       consensus    — deferral / voting / expertise / moderation        [folds in at 1.0]
  ├── one shared ciris-persist Engine    — the durable corpus + federation directory
  └── one shared ciris-edge runtime      — CEG/RET transport + the node's single federation identity

It authors no primitives; CEG and the cores own the grammar. CIRISServer is the wiring, the boot order, one unified identity endpoint (/v1/identity, the six-key LocalIdentityAggregate) — and the control surface below.

A node and a client — the UX handles

CIRISServer renders no UI of its own. It is also the client control surface: it exposes every fabric control handle upward, and rich UIs consume them. The handles (MISSION §3.4):

• Substrate handles — the node's federation identity (/v1/identity), federation-directory reads, content fetch, replication / health.
• Fabric handles — federation-identity minting (a hardware-rooted, YubiKey- or TPM/SE-sealed user identity → a CIRIS-V2- fedcode), node ownership (claim a node with its NodeCode + one-time PIN; the responsible owner-binding is infra:*, never agency), the per-role × per-axis trust/consent toggles, trust-graph management (untrust, re-root, create/join groups), canonical-group membership + voting, self/family occurrence attachment, and consent-object setup between peers (consent:replication).

Those handles are consumed by rich clients. Just like CIRISAgent, CIRISServer can run fully headless (the ciris-server binary + a CLI: e.g. ciris-server identity create --backend pkcs11 mints a YubiKey-backed federation ID) and it exposes a rich client — the same CIRISAgent Kotlin-Multiplatform app, minus the agent (brain) cards. The app is a node: it runs a local fabric node and drives it (all crypto stays in the substrate, never in the UI). It surfaces the fabric cards — create-your-federation-ID (mint the hardware-rooted ID from the desktop app), claim-a-node (NodeCode + PIN), the consent-objects card, the node switcher, and the holonomic scoreboard — without the reasoning/chat cards an agent adds. (Other rich clients: CIRISPortal, CIRISNode.) The infrastructure that holds the audit corpus is the surface that publishes it (redacted PDMA logs / WBD tickets / attestation reads, per the Accord's transparency requirement).

What it replaces

The three canonical nodes (lens + registry-us + registry-eu) become identical fabric nodes — the founding members of the ciris-canonical governed community, replicating via CEG over Reticulum (no Spock, no DNS).

• The CIRISRegistry singleton servers go away. Each node handles its own key the way the lens already does (per-node identity, no shared vault key); the three per-node keys are the 2-of-3 registry-consensus quorum.
• The CIRISLens deployment goes away — Python ingest + TimescaleDB + Grafana retired. A central dashboard the whole federation reads is itself the singleton this architecture forbids. The lens function lives as ciris-lens-core inside every fabric node, over the shared substrate, queryable from any node.

The repos (ciris-registry-core, ciris-lens-core, ciris-node-core) stay — they are the libraries this binary composes, the same cores that fold into CIRISAgent.

Install

pip install ciris-server      # the PyO3 abi3 wheel (or build the binary: cargo build --release)
ciris-server                  # boots a zero-setup node — mode=server, trusts ciris-canonical, no wizard
                              # on a fresh (unclaimed) node it prints its NodeCode + one-time claim PIN

# Headless: mint a hardware-rooted federation ID (or do it from the desktop app)
ciris-server identity create --backend pkcs11   # YubiKey-backed; --backend platform-sealed (TPM/SE) | software (dev)
                                                # prints your CIRIS-V2- fedcode + key_id

Defaults need no setup: data under $CIRIS_HOME, SQLite corpus (Postgres via CIRIS_DB_URL), identity minted-or-migrated on first boot, Reticulum transport up, the lens read API on listen+1. Migrating a deployed CIRISLens host? See FSD/LENS_TO_SERVER_MIGRATION.md — the federation key and RNS address carry over byte-identically (no re-key).

The same wheel gives CIRISAgent the lens drop-in: from ciris_server import LensClient.

Status

Shipped (0.3.0) — the integrated fabric node. ciris-server boots a zero-setup node: relay ingest (CEG AccordEventsBatch over Reticulum/HTTP) + the seven frozen GET /lens/api/v1/* read endpoints + the six-key GET /v1/identity, over one shared persist Engine. Federation signatures are 100% hybrid post-quantum (Ed25519 + ML-DSA-65, hard cut — no classical-only path); the sealed-Ed25519 federation seed and the RNS transport identity are TPM/SE/StrongBox sealed (software-encrypted fallback) and adopted byte-identically on a CIRISLens takeover (no re-key).

0.3.0 adds the auth subsystem (src/auth/, CIRISServer#9) — the fabric is the single auth authority: one x-ciris-* hybrid request verifier, self-at-login (so consent/erasure are user-signed), OAuth + sessions + roles/perms + api-keys + user-signed consent + CEG-native erasure (GDPR Art. 17), all a byte-compatible port of the agent's wa_cert-backed auth — and the one-wheel re-export (CIRISServer#4) so CIRISAgent consumes a single ciris_server .so (one PyO3 registry). Also shipped: legacy-trace import (ciris-server import-traces), the holonomic federation scoreboard (ciris-server scoreboard) + the interpreted capability page at https://cirisai.github.io/CIRISServer/, and the §19.7 noise-floor compliance bench. Below the lens-store disk minimum the node degrades to a Reticulum relay node.

Substrate floor: persist v8.6.0 / edge v4.5.0 / verify-family v5.11.0 (CEG 1.0-RC12). ciris-lens-core is absorbed in-tree — the standalone CIRISLensCore library and the CIRISLens deployment (Grafana/TimescaleDB/Python ingest) retire. Cohabitation + CEG-profile conformance is gated by CIRISConformance against the published wheels.

Roadmap (driven by the CIRISAgent train):

• 0.5 (config-as-CEG — zero env vars) — all node config is signed CEG objects (owner-authored, runtime-reconciled, replicated); the fabric IS the config, the same way the agent IS its graph.
• 0.6 (+ registry authority) — agent ~2.9.8/9. Prep: FSD/REGISTRY_FOLD_DERISK.md, #2.
• 1.0 (+ node consensus — the complete fabric node) — agent ~2.9.10.

The wiring needs no core changes — CIRISServer adapts to what's shipped. See FSD/SERVER_1.0_PLAN.md.
