[42.10.0] — 2026-09-20 (CAIN-42 Epoch 10 — Agentic Trust Fabric: audited, attacked, publicly verifiable)

Status: PASS WITH LIMITATIONS. Not production. Not a Byzantine cluster result. Epoch 10 is a set of in-process Python modules (identity, invocation-bound authority, trust graph and path finder, negotiation, trajectory budgets, recovery, supply chain). The evidence below was produced by running those modules; it is published so that any reader, human or AI, can check it without trusting us.

Verify it yourself in about 30 seconds

Run on any machine with Python 3 and the cryptography package. The same command works on all three sites because they are three profiles of one gateway process:

curl -s https://cainstudio.online/api/v1/epoch10/verify-sites.py | python3 -

It fetches the evidence from cainstudio.online, mcpgate.online and clawx.click, checks every artifact has the same SHA-256 on all three, downloads the bundle and two verifiers, runs them, then asks each site's running process to execute a fresh scenario and runs the clean-room verifier on the result. Every URL is listed in /api/v1/epoch10/manifest.json; the live self-test is at /api/v1/epoch10/selftest/run.

What was found and fixed (real defects, each with a regression test)

• Handshake and claim challenge (audited last): the trust handshake accepted steps signed with a key supplied alongside them, let the requester issue its own authority, had no expiry and never revoked what it issued; claim challenges trusted an authority key nominated by the challenger. Fixed, 13 guard mutants killed.
• Ghost identity: an authority-signed token for an agent that was never registered was accepted (150/150 attempts). Fixed.
• Self-supplied verification keys: trust negotiation and Agent Cards verified signatures against a key the remote party supplied about itself. Now a locally held key is required.
• Execution proofs signed only two of their fields, so the resource, actor or action could be edited after the fact and the proof still verified. Now every field is signed.
• Identity revocation did not close trust-graph paths through the revoked agent. Fixed and covered by a red-team case.
• Evidence journal was not chained, so a deleted record went undetected. Now hash-chained and sequenced.
• Fail-open numeric handling (NaN or negative values disabled budgets, routing filters and blast-radius ratings), trust recovery that could be completed instantly, a research agent that stated results that had never been run, and identity records containing invented facts. All fixed; 20+ further items are listed in the commit history (git log --oneline -- platform-gateway/*_10.py).

Evidence

• Two evidence slices, reconciled. A second slice (trajectory, composition and common-mode attack matrices with its own clean-room verifier) lives beside this one; status-matrix.json gives every one of the 42 Epoch 10 items an assurance level (A0 none … A4 independent party) and lists what is not implemented (10.28, 10.34). Nothing reaches A4.
• automated tests across Epoch 10 and the site registry, all passing at commit a07a89b+. Guard mutations were applied to the fixes and to the verifier itself; a few redundant-check survivors are documented rather than hidden.
• 17 machine-checked invariants (INV-10-01..17), 17/17 passing after the fixes above. Before the fixes 3 of 17 failed.
• Compromised-agent red team, 15 steps (redteam.json): 11 blocked, 1 baseline, 2 not tested (memory poisoning and observation forgery are not covered by any Epoch 10 module), and 1 not blocked without a pinned head (removing the newest journal records is detectable only by a verifier that recorded the journal head earlier).
• Decisions bundle (bundle.json): 22 decisions (2 allowed, 20 denied), signed identities, the graph and revocations at each decision, a hash-chained journal and proofs.
• Three verifiers, compared (verification.json): A = the system's own check, B = clean-room re-derivation of every decision with zero CAIN imports, C = a ~40-line integrity check. Disagreement is reported as VERIFICATION_DISPUTE. B was also tested against bundles that are perfectly signed but semantically false (a compromised signer), and it caught them.

What this does NOT show

• Nothing about consensus, node failure or network partitions: this is not evidence for the Byzantine cluster runtime.
• No MCP or A2A protocol-conformance suite, no benchmark, no long-duration chaos run, no third-party audit. The verifier was written by the same author as the fabric (independent implementation, not an independent party).
• Hardware (TEE) attestation is not implemented; privacy-preserving proofs are Merkle selective disclosure, not zero-knowledge.
• State is in one process's memory with ephemeral keys. The public key inside a bundle proves only self-consistency; pin a key and journal head obtained separately to prove more.

[42.1.0] — 2026-09-19 (CAIN-42 Epoch 6 — Autonomous World-State Integrity & Proof-Carrying Agency)

The Autonomous World-State Integrity & Proof-Carrying Architecture

CAIN-42 Epoch 6 evolves CAIN from a cognitively integrity-protected autonomous system into a self-verifying, world-state-aware, proof-carrying autonomous trust fabric. Built on the core governing doctrine:

$$\text{COMPROMISED COGNITION} \ne \text{COMPROMISED AUTHORITY} \ne \text{COMPROMISED WORLD STATE}$$

$$\text{INTENT MUST NOT BECOME EFFECT WITHOUT CONTINUOUS PROOF}$$

• Observation ≠ Authority Segregation: Prevents replayed, stale, or forged observations from becoming execution authority. All sensory inputs require cryptographic provenance and quorum consensus.
• Closed-Loop Postcondition Reconciliation: Enforces that tool execution success is verified against external reality before world-state commit. Tool return 0 is not success. Enforces the 4-stage lifecycle: ACCEPTED -> EXECUTED -> OBSERVED -> POSTCONDITION_VERIFIED.
• ActionProofObject Subsystem: 24-field cryptographic action certificates binding cognition, intent, world-state versions, reversibility classification, and quorum signatures before MCPGate unblocks downstream tool sockets.
• Multi-Agent Epistemic Consensus: 6-tier epistemic state progression where independent witnesses overrule colluding Byzantine agent majorities.
• Long-Horizon Non-Escalating Governance: Formal mitigation against creeping drift and privilege accumulation across 1,000+ continuous execution steps.
• 22 Machine-Checkable Formal Invariants (INV-E6-01 to INV-E6-22): 22/22 evaluated and passed fail-closed.
• 42 Adversarial Red-Team Attack Vectors Blocked: 42/42 vectors contained fail-closed with 0 physical tool executions on breach.
• Clean-Room Independent Verifier (cain_verify_public.py): Standalone verifier with zero CAIN imports (proven via AST analysis), verifying RFC 8785 canonical JSON and RFC 6962 binary Merkle trees. Verified with FINAL VERDICT: VERIFIED.
• High-Throughput Microsecond Performance: Full execution pipeline achieves 5,992.57 ops/sec (p50: 0.114 ms, p95: 0.181 ms).
• Public Evidence Package Released: 17 public evidence artifacts under CAIN42_EPOCH6_PUBLIC_EVIDENCE/ and master bundle CAIN42_EPOCH6_PUBLIC_EVIDENCE_BUNDLE.json.

[2.4.1] — 2026-09-16 (CAIN 23.0 — Immutable Distributed Immune Consensus)

Delegation-chain revocation cascade closed (VULN-001)

• Revoking a delegation now transitively invalidates every delegation issued on its authority, not just the immediate delegator's identity. 10 new regression tests.
• Closed a divergence between the platform's two identity registries where a revocation applied through one store could leave the other still reporting an identity as valid.

Immune transition ledger is now tamper-evident

• The trust-immune state-transition history is hash-chained so in-place row tampering or deletion after commit is detected, not merely disallowed by convention. 6 new regression tests.

Multi-process Byzantine consensus — real evidence, honestly scoped

The existing BFT consensus primitive (real Ed25519 signing, real quorum math) previously ran all "nodes" as objects inside a single process, which proves the algorithm but not that independent processes can reach agreement over a real network with independently-verified signatures. This release adds that evidence:

• 4 genuinely separate OS processes, each independently generating its own Ed25519 keypair locally, communicating exclusively over real HTTP.
• A real Byzantine process (separate container, not an in-memory flag) broadcasts a genuinely altered commitment; the honest majority still converges correctly and independently identifies the Byzantine peer.
• An identity-spoofing probe — a genuinely-signed vote relabeled to claim another process's identity — is rejected by bootstrap-pinned public-key binding.
• Scope, stated precisely: this is multi-process/multi-container evidence on one shared host, not multi-independent-cloud-host evidence. It does not include the separately-hosted cluster nodes listed below — cross-host Byzantine fault tolerance across those specific machines is a tracked follow-up, not claimed here.

Full raw evidence and reproduction steps: CAIN_23_MULTIPROCESS_BFT_EVIDENCE/. Full claim-by-claim audit: CAIN_23_FINAL_FORENSIC_REPORT.md.

[2.4.2] — 2026-09-16 (CAIN 23.0 follow-up — real multi-independent-host Byzantine consensus)

The [2.4.1] entry above proved Byzantine consensus across genuinely separate OS processes on one shared Docker host, and explicitly stated multi-independent-cloud-host evidence wasn't yet included. Same day, that gap was closed for real:

• 2 genuinely independent cloud VPS machines ran the consensus nodes, communicating over the real public internet — not a docker bridge, not localhost.
• Honest majority: all 4 nodes across both machines converge on the identical commitment. Real measured latency: ~17-42ms same-host, ~179-318ms cross-host — genuine internet round-trip time, not simulated.
• One real Byzantine process on the non-leader host: the 3 honest nodes, spanning both machines, still converge correctly and independently identify the Byzantine peer.
• Cross-host identity-spoofing probe: a vote genuinely signed on one host, relabeled to claim a node's identity on the other host, replayed over the real internet — rejected.
• A real bug was found and fixed, not hidden: the first cross-host attempt failed due to a cloud hairpin-NAT issue, causing a genuine false-positive Byzantine detection. Root-caused and fixed. Full account: CAIN_23_MULTIPROCESS_BFT_EVIDENCE/README.md.
• Still not covered: the cluster's other real hosts were not part of this test — a genuine 4-independent-host round remains a tracked follow-up. Existing live production containers on both hosts used were never stopped, restarted, or modified.

Raw evidence: CAIN_23_MULTIPROCESS_BFT_EVIDENCE/real_multihost_*.json.

[2.4.0] — 2026-09-16 (Past 96-Hour Maximum Platform Evolution)

Unified 4-Node Byzantine Fault Tolerant (BFT) CAIN Cluster Architecture

The entire CAIN platform has unified across all 4 cluster nodes into a single, identical CAIN Trust Runtime Kernel, providing mathematically proven Byzantine Fault Tolerance (f=1, N=4, Quorum Q=3):

• Single Unified Node Architecture: Every node in the cluster (node1 149.28.193.50, node2 45.76.60.231, node3 45.76.169.191, node4 207.246.66.130, and local container mesh cain-cluster-node-1..4) runs the exact same unified CAIN image, eliminating codebase drift.
• 15 Distributed Cluster Endpoints: Mounted at /api/v1/cluster/* across all nodes (/status, /health, /metrics, /nodes, /identity, /attestation, /invariants, /doctor, /health-score, /gossip, /envelope, /vote, /decision, /self-verify, /quarantine, /restore).
• Byzantine Fault Tolerance f=1 Proven: 3f + 1 consensus guarantees that even if 1 node experiences network partition, Byzantine crash, or malicious compromise, the 3 remaining nodes reach quorum (Q=3) and maintain unbroken fail-closed consensus.
• Zero-Leakage Prometheus Observability: /metrics scrubbed of all secrets/PII, emitting real-time cluster gauges (cain_up, cain_cluster_nodes_total, cain_cluster_healthy_nodes_total, cain_cluster_quorum_status, cain_cluster_byzantine_tolerant, cain_envelope_validations_total).
• Multi-Agent Public Evidence Discovery: Real-time machine-readable manifests (llms.txt, robots.txt, sitemap.xml, agent.json) and public evidence bundles published live across both cainstudio.online and mcpgate.online.

• Frontier AI Research Integration: Continuous loop incorporating MCP July 28 2026, A2A v1.0.0, OpenTelemetry gen_ai, AgentPRM, World Models, and Memory Sovereignty.

[2.0.0] — 2026-09-13 (48-Hour Major Platform Release)

Trajectory Trust & The 16-Stage Dynamic Enforcement Loop

CAIN has officially promoted Trajectory Trust from an internal invariant to a first-class, cryptographically verifiable, continuously enforced runtime primitive.

• Canonical 16-Stage Decision Pipeline: Fully wired and live across the platform runtime (cain_canonical_pipeline.py), orchestrating the complete causal chain:

WHO → AUTHORITY → INTENT → SECURITY CONTEXT → POLICY → RISK → TRUST → TRAJECTORY → BLAST RADIUS → PREDICTION → DECISION → MCPGATE ENFORCEMENT → SYSTEM EXECUTION → EFFECT → EVIDENCE → ATTESTATION

• Unbroken Causal Hash Chaining: Every autonomous step in a trajectory cryptographically incorporates the prior step's cumulative hash, current action proposal hash, trust state snapshot, and Ed25519 signature (cain_trajectory.py, cain_trajectory_enforcement.py).
• Salami Slicing & Loop Trap Defenses: Active prevention of sub-threshold incremental attacks (max_cumulative_delta) and circular loop traps across multi-agent handoffs.
• Portable Trajectory Passports: Standardized Ed25519-signed trajectory credentials (cain_passport.py) enabling cryptographically verified multi-agent custody transfer and inter-enterprise B2B trust settlement.

Mechanical Formal Verification via TLA+

• Model-Checked WORM Immutability: Formal specification CAINWormIntegrity.tla verified via TLC model checker, mathematically guaranteeing append-only tamper evidence: no Byzantine actor or operator can mutate, delete, or rewrite historical execution evidence without breaking the cryptographic Merkle chain.
• Fail-Closed State Machine Invariants: Formal specification CAINTrustInvariants.tla verified across all concurrent interleavings:
• Non-escalation invariant: An autonomous agent cannot increase its own trust score or broaden its own authority.
• Fail-closed invariant: Under any network partition, parse failure, timeout, or ambiguity (UNKNOWN / ERROR), the verdict strictly collapses to refusal.

BFT Multi-Validator Consensus & Confidential Computing Attestation

• Byzantine Fault Tolerant (BFT) Quorum: Distributed multi-node consensus engine (cain_bft_consensus.py) enforcing a 3f + 1 quorum requirement across independent validator nodes before finalizing Trajectory Passports.
