Changelog

All notable changes to the CAGE reference implementation are documented here.

The format follows Keep a Changelog. Versions follow Semantic Versioning.

3.0.0 - 2026-09-07

Major Version Release: Architectural cleanup, formal safety consolidations, governed threshold centralization, RFC 8785 JCS canonicalization, 6-primitive governance runtime (PAUSE/NARROW/DEFER), Lua-atomic CBF, provider integrations, Cilium L7 CNI abstraction layer, and ClickHouse compliance telemetry. See docs/BREAKING_CHANGES_v3.md for full migration guidance.

Cilium & Compliance Telemetry (2026-09-07)

feat(infra)! — CNI Abstraction Layer for Cilium L7 Overlay

  • Cilium NetworkPolicy Directory — Added deployment/k8s/cilium/ containing three CiliumNetworkPolicy resources: egress-lockdown.yaml (FQDN allowlist for gateway, sovereign-agent, and financial-advisor pods), reconciliation-worker-egress.yaml (egress isolation for the reconciliation CronJob), and trivy-egress-fqdn.yaml (Trivy scanner allowlist). These extend the portable networking.k8s.io/v1 baseline with L7 DNS-aware filtering on GKE Dataplane V2 / Cilium-enabled clusters.
  • AgentSight DaemonSet — Updated deployment/k8s/agentsight-daemon.yaml with updated pod spec.
  • Terraform GKE Module — infra/modules/gcp_gke_cluster/main.tf and variables.tf updated with Cilium/Dataplane V2 configuration variables.
  • Terraform GKE Target — infra/targets/gcp-gke/main.tf updated to pass CNI configuration through the cluster module.
  • Staging TFVars — infra/targets/gcp-gke/staging.tfvars updated with CNI-related settings.

feat(compliance) — Cilium Telemetry Integration and ClickHouse Evidence Stream

  • src/compliance_bridge/clickhouse_sink.py — New ClickHouse sink for streaming infrastructure telemetry events from the compliance bridge.
  • src/compliance_bridge/main.py — Added infrastructure event telemetry endpoint and Cilium telemetry pipeline.
  • src/compliance_bridge/types.py — New types for infrastructure compliance events.
  • compliance/lula/lula-validation-cilium-dpv2.yaml — New Lula validation asserting that the GKE Dataplane V2 anetd DaemonSet is scheduled and ready on all nodes (NIST SP 800-53 SC-7 — Boundary Protection).
  • deployment/clickhouse/evidence_stream_schema.sql — Added schema for Cilium telemetry evidence stream.
  • Prod TFVars — prod.tfvars, eu-prod.tfvars, apac-prod.tfvars updated with Cilium/DPv2 settings for production regions.

fix(governance) — Feature-Flag Isolation for xdist Safety

  • src/gateway/governance/symbolic_governor.py — Isolated feature-flag reads to prevent state leakage between parallel test workers when running pytest -n auto. Flags are now read per-invocation rather than cached at module import time.
  • tests/test_classify_violation.py — Added test coverage for feature-flag isolation behavior.

fix(nemo) — Correct self_check Import Paths

  • config/rails/actions.py — Fixed self_check_input and self_check_output import paths to match the installed nemoguardrails package structure (nemoguardrails.library.self_check.input_check.actions / nemoguardrails.library.self_check.output_check.actions).
  • src/gateway/governance/nemo/manager.py — Removed unsupported context keyword argument; fixed pre_check method signature.
  • src/gateway/server/inference_proxy.py — Updated NeMo pre-check call to match corrected signature.

fix(compliance) — Lula Validation Schema and Bridge Config

  • compliance/lula/lula-validation-cilium-dpv2.yaml — Updated Lula validation schema to match current Lula version requirements.
  • infra/modules/compliance_bridge/main.tf — Added compliance bridge Terraform configuration.

style(tests) / fix(tests) — Test Hygiene

  • tests/test_pause_primitive.py — Applied ruff formatter; patched dynamic feature flags to prevent cross-worker state pollution in xdist runs.

Breaking Changes

PR A — Capability-Driven Tier Dispatch

  • Legacy Inline Dispatch Removed — The inline consensus gate, causal gatekeeper, FRIA/normative provider, and CBF/fiscal blocks have been deleted from SymbolicGovernor._run_checks(). These mechanisms are replaced by the tier dispatch loop (_run_domain_tiers()) that executes registered GovernanceTierPlugin instances. This is a hollowing refactor: the kernel now denies all actions by default until PR C restores functionality as domain plugins (refactor(governance)!).

  • RefusalReceipt Schema v3 — RefusalReceipt.schema_version default changed from "v1" to "v3". Schema v3 includes the tier_failures tuple field for multi-tier governance. The proof_hash computation now includes tier_failures when schema_version != "v1". Existing receipt consumers must handle both v1/v2 legacy receipts and v3 receipts (feat(governance)!).

  • Domain Literals Removed — Hardcoded domain action references ("execute_trade", "reverse_trade") removed from kernel code (hybrid_server.py, telemetry_provider.py, ontology.py). Domain-specific warmup, telemetry filtering, and constraints moved to domain plugins per the Three-Layer Split Rule. Gate G6 enforces this in CI (refactor(governance)!).

  • Method Signature Changes — SymbolicGovernor.revalidate_post_hitl() and pre_check() no longer accept tool_name with a default value. The action parameter is now required. Callers must explicitly provide the action name (refactor(governance)!).

PR B — Sever Kernel → Plugin Imports

  • Layer Isolation Enforced — All Layer 1 (src/gateway/) → Layer 2 (src/cage_*) import dependencies removed. The kernel now uses plugin-supplied components via install_domain_components() rather than directly importing domain modules. CI gate G3 (scripts/check_import_boundaries.py) now blocks on violations (refactor(governance)!).

  • Fail-Closed Null Components — Kernel singletons (safety_filter, consensus_engine) default to NullSafetyFilter and NullConsensusProvider in bare-kernel mode (CAGE_ACTIVE_PLUGINS=""). These null objects explicitly deny all requests rather than silently failing or allowing. Plugins must call install_domain_components() to install real implementations (refactor(governance)!).

  • Startup Readiness Assertions — Server lifespans (mcp_tool_server.py, hybrid_server.py) now assert that domain components were installed if plugins are expected. Missing components cause startup to fail loudly with RuntimeError rather than silently defaulting to null objects (feat(governance)!).

  • Background Task Registry — Plugin-supplied long-running coroutines (e.g. consensus audit worker) must register via register_background_task() rather than being directly imported into hybrid_server.py. The kernel calls background_tasks.start_all() to launch registered tasks (refactor(governance)!).

  • HITL Constants Relocated — Human-in-the-loop escalation parameters (HITL_CITATIONS, HITL_SLA_HOURS, PII_RETENTION_AUTHORITY, INJECTION_CITATION) moved from cage_finance/constants.py to the _hitl section of regional baseline JSONs (config/thresholds/*_BASELINE.json). These are regulatory constants, not domain-specific, and belong in region posture config (TODO(PR-C-OSCAL): update OSCAL component definitions to reference new baseline locations) (refactor(governance)!).

Vendor Decoupling Program (AW-1 through AW-8)

  • Explicit Cold Storage Selection (AW-1, AW-7) — Eliminated implicit GCS activation. Storage selection requires explicit EVIDENCE_COLD_STORE ∈ {gcs, s3, null} (defaults to null). Running CAGE_ENV=prod with EVIDENCE_COLD_STORE=null fails fast on startup unless CAGE_ALLOW_NONBLOCKING_PROD=true is set (refactor(compliance)!).

  • Vendor-Neutral Storage Configuration (AW-2) — Removed EVIDENCE_STREAM_GCS_BUCKET* variables in favor of EVIDENCE_COLD_STORE_BUCKET* and declarative configuration in config/compliance/residency.json. No legacy alias is read (refactor(compliance)!).

  • OSCAL S3 Dispatcher Consolidation (AW-3) — Consolidated duplicate S3/GCS storage dispatch in storage.py into the unified EvidenceColdStore abstraction (refactor(compliance)!).

  • Evidence Stream Promoted to Kernel (AW-4) — Promoted src/compliance_bridge/evidence_stream.py to src/gateway/governance/evidence/stream.py. Severed all Layer 1 → Layer 3 imports. No backward compatibility shim is provided; stale imports fail loudly (refactor(governance)!).

  • CBF Compatibility Shim Deleted (AW-5) — Removed deprecated src/cage_finance/safety/cbf.py shim; canonical CBF engine resides in kernel (refactor(governance)!).

  • Telemetry Vendor String Neutrality (AW-6) — Eliminated raw "langfuse.*" string literals outside src/gateway/observability/attributes.py. Enforced in CI via Gate G7 (refactor(gateway)!).

  • Explicit Telemetry Provider Selection (AW-8) — Removed silent fallback to MockTelemetryProvider when credentials are absent; missing credentials with langfuse selected now fails fast with ConfigurationError (fix(gateway)!).

Plugin Architecture & Provider Protocol (PR #108–#114)

  • Legacy Trade Dispatch API Removed (PR #111) — The deprecated trade dispatch API in src/governed_financial_advisor/ has been removed as part of the GFA-kernel decoupling initiative. All trade execution now flows through the canonical execution actuator protocol. Legacy clients must migrate to the /v1/execute endpoint with proper governance envelope wrapping (refactor(governance)!).

  • Compliance Bridge Escalation Authentication (PR #114) — The POST /v1/defer/{defer_id}/escalate endpoint now requires an authenticated request body with a valid routing seal or governance envelope. Previously, this endpoint accepted unauthenticated escalation requests, creating a potential authorization bypass. Clients must now include proper authentication credentials in the request body (feat(compliance)!).

Added

  • Normative Provider Protocol — Unified vendor adapter protocol (NormativeProvider, AttestationProvider, EnvelopeMapper) with universal conformance test suite. All external partner integrations now implement standardized seams with fail-closed semantics, tri-state verdict mapping, and hermetic testing (PR #108–#114) (feat(governance)).

  • Universal Protocol Conformance Suite — Parameterized test suite in tests/test_normative_provider_conformance.py validating all vendor adapters against canonical interface contracts across all deployment regions (test(governance)).

  • Plugin Isolation Boundary Check — New scripts/check_import_boundaries.py script enforcing vendor package isolation: adapter code under src/integrations/provider_*/ must never import from core CAGE kernel (src/gateway/). Violations fail CI (ci(governance)).

Changed

  • Vendor Package Isolation — All external vendor adapters moved to isolated packages under src/integrations/provider_{name}/ with strict import boundary enforcement. Core CAGE kernel dependencies flow through protocol seams only (refactor(governance)).

  • OSCAL Component Updates — Updated OSCAL component definitions and system security plan to reflect plugin architecture refactor (PR #115) (chore(compliance)).

Migration Guide

Legacy Trade Dispatch API Removal

Before (removed in v3.0.0):

# Legacy direct trade dispatch (removed)
response = requests.post(
    "http://gfa:8080/legacy/trade/dispatch", json={"symbol": "AAPL", "quantity": 100}
)

After (required in v3.0.0):

# Use canonical execution actuator protocol
from src.gateway.governance.governance_envelope import GovernanceEnvelopeBuilder

envelope = GovernanceEnvelopeBuilder.build(
    action="execute_trade",
    payload={"symbol": "AAPL", "quantity": 100},
    seal=routing_seal,
)
response = requests.post("http://gateway:8080/v1/execute", json=envelope.to_dict())

Compliance Bridge Escalation Authentication

Before (removed in v3.0.0):

# Unauthenticated escalation (security vulnerability)
response = requests.post(
    f"http://compliance-bridge:3002/v1/defer/{defer_id}/escalate",
    json={"reason": "business justification"},
)

After (required in v3.0.0):

# Authenticated escalation with routing seal
from src.gateway.governance.routing_seal import generate_seal

seal = generate_seal(
    action="escalate_defer", record_hash=defer_record_hash, secret=ROUTING_SEAL_SECRET
)
response = requests.post(
    f"http://compliance-bridge:3002/v1/defer/{defer_id}/escalate",
    json={

        "requester_identity": "user@example.com",
    },
)

Core Architecture & Security Hardening

Backward-Compatibility Remediation & JCS Migration (BC-01–BC-08)

  • Canonicalization (BC-01) — RFC 8785 JCS migration completed across src/: every executable json.dumps(..., sort_keys=True) canonicalization site now uses jcs_canonicalize_plan(). Affects the ContextAccumulator and EvidenceStreamSink hash chains (write and verify migrated atomically), the WORM/KMS UCA signing path, ConsequenceToken JWS envelopes, routing seals, OPA/query cache keys, the reconciliation signed balance, the control-registry profile hash, and provider receipt/state digests. Closes POAM-2026-060 (refactor(compliance)!)
  • Schema Sentinels (BC-02) — cage-evidence-stream/1.1 → /2.0 and cage-context-accumulator/1.1 → /2.0; records written pre-change do not verify (refactor(compliance)!)
  • WORM/KMS Signing (BC-03) — uca_logger._sign_record() migrated to JCS with no compatibility shim; previously-signed WORM records will not verify (refactor(governance)!)
  • FlowSignal Decision Field (BC-04) — src/integrations/provider_01/provider.py: FlowSignal decision field is now mandatory; a missing or unrecognized value fails closed with code="cage.endpoint_error" instead of falling back to the legacy binary admitted/findings shape. Closes a latent fail-open; POAM-2026-064 (fix(governance)!)
  • Canonical Decisions (BC-05) — src/gateway/governance/provenance_chain.py: VALID_DECISIONS narrowed from eight to the canonical six (ALLOW, DENY, DEFER, NARROW, PAUSE, REQUIRE_APPROVAL); legacy BLOCK/ESCALATE rejected. POAM-2026-065 (refactor(governance)!)
  • Fiscal Limit Rollback (BC-07) — src/gateway/governance/fiscal_limit_guard.py: rollback() now raises ValueError without an explicit window_key or token, restoring the POAM-2026-058 cross-window guard the legacy fallback defeated. POAM-2026-067 (fix(governance)!)
  • Regional Compliance Prerequisite (BC-08) — src/gateway/governance/constants.py: a missing regional compliance profile now raises RuntimeError at startup instead of degrading to a region="LEGACY" profile; deployments must provision config/compliance/{REGION}_BASELINE.json. POAM-2026-068 (fix(governance)!)

Removals & Deprecations (SR-1–SR-7, MR-1–MR-4, CR-1–CR-3)

  • Removed stpa_validator.py shim module — use GeneratedSTPAValidator directly (SR-1)
  • Removed safety.py re-export shim — import from text_filter and cbf directly (SR-2)
  • Removed GovernanceClient, RedisClient, HybridClient aliases — use StructuredLLMClient and AsyncRedisClient (SR-3, SR-4, SR-5)
  • Removed check_safety_constraints legacy tool alias — use simulate_governance_check (SR-6)
  • Removed create_ftra_node() deprecated params (registry_path, plan_key) — kwargs no longer accepted; pass a FtraNodeConfig instance instead (SR-7)
  • Removed CONTROL_META, EVIDENCE_SLA_SECONDS, ISO_CONTROL_MAP aliases — use region-aware accessors get_control_meta(), get_sla_seconds(), get_iso_control_map() (MR-1, MR-2, MR-3)
  • Removed config/settings.py module-level aliases — use Config.X class attributes (MR-4)
  • Migrated threshold env vars to config/governance_thresholds.json (env vars still work as overrides) (EV-1–EV-6)
  • (CR-1 / POAM-2026-062) Removed Evidence Stream v1.0 schema support — v1.1 is now the only supported schema; dual-schema machinery deleted (_detect_schema_version(), migrate_record_1_0_to_1_1(), get_last_v1_0_hash(), _link_hash_v1_1(), EvidenceRecord.schema_version)
  • (CR-2) Removed NeMo auto-apply path (NEMO_AUTO_APPLY_ENABLED) — all refinements require human approval via /v1/nemo/propose-refinement and /v1/nemo/approve-refinement/{proposal_id}
  • (CR-3) Renamed update_state() → _update_state_unsafe() — use atomic_verify_and_commit() instead
  • Removed AGWEnvelope/AGWEnvelopeBuilder backward-compatibility aliases (src/gateway/governance/agw_envelope.py, entire file deleted) — use GovernanceEnvelope/GovernanceEnvelopeBuilder from src/gateway/governance/governance_envelope.py
  • Removed legacy sign_provider_04_digest() method from KMSSigner (src/gateway/governance/kms_signer.py) — use sign() instead
  • Removed Provider 03 backward-compatibility aliases (fetch_legal_baseline(), validate_external_fria(), submit_evidence_chain()) (POAM-2026-063)
  • Removed duplicated legacy DEFER response fields (verdict, defer_id, missing_input_reason) — canonical fields are decision, defer_token, classification_reason (POAM-2026-066)

Added

  • tests/test_tls_enforcement.py — Gateway TLS enforcement test suite: unit assertions for NIST SP 800-52 Rev. 2 TLS 1.2+ protocol minimums, OIDC JWKS verify=True transport security, and Linkerd mTLS manifest annotations (test(compliance), closes POAM-2026-011)
  • docs/operations/KEY_ROTATION.md — Cryptographic key management & rotation guide: documented rotation cadences for Cloud KMS HSM keys (90-day), HMAC routing seal secrets (30-day), and Linkerd mTLS certs with zero-downtime procedures and emergency revocation runbooks (docs(operations), closes POAM-2026-012)
  • deployment/k8s/ manifests — Pinned third-party container image tags: openpolicyagent/opa:0.68.0-static, redis/redis-stack-server:7.4.0-v1, and anchore/syft:v1.10.0 across deployment manifests (feat(infra), closes POAM-2026-013)
  • AGENTS.md — Parallel test isolation standards: added mandatory --dist=loadfile flag requirement and targeted test command reference matrix (docs(tests))
  • src/gateway/governance/symbolic_governor.py — PAUSE handler in validate_action(): first-class runtime execution path returning verdict: PAUSE, pause token, resume endpoint, and retry metadata (feat(governance))
  • src/gateway/governance/routing_seal.py — HMAC Routing Seal v2: 4-tuple format <expire_hex>.<action_slug>.<record_hash_hex>.<hmac_hex> binding SHA-256 evidence record hash with fail-closed actuator enforcement (feat(governance))
  • src/gateway/governance/cbf.py — Strict replication rollback & cold-start epoch seed: synchronous Redis WAIT verification with fail-closed automatic rollback on replica timeout, plus _fetch_initial_fence_epoch_sync() startup seeding (feat(governance))
  • src/compliance_bridge/evidence_stream.py — Precondition validation: validate_evidence_stream_preconditions() halts startup in production if non-blocking evidence mode is configured (fix(compliance))
  • proof/model.py, proof/distributed_cbf_model.py — Formal state model expansion: 57-state sequential and 66-state concurrent BFS models verifying NoDirectBind invariant across all paths, plus $N$-agent distributed barrier proofs (test(formal))
  • src/gateway/governance/pause_primitive.py, src/gateway/server/hybrid_server.py — PAUSE primitive and resume endpoint: new POST /v1/pause/{pause_token}/resume and GET /v1/pause/{pause_token} endpoints for resumable execution suspension (feat(governance))
  • src/gateway/governance/decisions.py, src/gateway/governance/symbolic_governor.py — NARROW primitive: new NARROW governance decision for partial-authority execution with clamped scope (gated by CAGE_NARROW_ENABLED) (feat(governance))
  • src/gateway/governance/symbolic_governor.py:_classify_violation() — DEFER classification helper: five-way classification (DENY/DEFER/NARROW/PAUSE/REQUIRE_APPROVAL) with DeferQueue integration (feat(governance))
  • src/governed_financial_advisor/graph/state.py — AgentState NARROW/PAUSE fields: added narrow_status, narrowed_params, pause_resume_token, pause_reason fields (feat(governance))

  • src/gateway/governance/cbf.py — Redis fence epoch: safety:fence_epoch monotonic counter for failover safety (gated by CAGE_REDIS_SYNCHRONOUS_REPLICATION, default true) (feat(governance))
  • src/gateway/governance/cbf.py, src/compliance_bridge/reconciliation_worker.py — Reconciliation replay defense: monotonic sequence numbers prevent payload replay attacks (gated by CAGE_RECONCILIATION_REPLAY_DEFENSE) (feat(governance))
  • config/governance_thresholds.json v2.0.0 schema with FRIA, confidence, and causal thresholds
  • Threshold accessor functions in src/gateway/governance/schemas/thresholds.py
  • Region-aware control metadata accessors (get_control_meta(), get_sla_seconds(), get_iso_control_map())

Changed

  • src/compliance_bridge/evidence_stream.py — Evidence chain blocking default: EVIDENCE_CHAIN_BLOCKING now defaults to "true" (peer review Fix B) (fix(compliance))
  • src/gateway/governance/symbolic_governor.py:_ftra_boundary_check() — FTRA boundary check mandatory: now runs unconditionally (flag CAGE_FTRA_BOUNDARY_ENABLED removed per POAM-2026-030-B) (fix(governance))
  • FtraNodeConfig is now required for create_ftra_node() (no fallback extractors)
  • Threshold values loaded from config file with env var overrides
  • SafetyBoundaryProtocol no longer exposes update_state() method

Removed

  • src/compliance_bridge/evidence_stream.py — Evidence chain v1.0 schema support: removed deprecated _SCHEMA_1_0/_SCHEMA_1_1 constants; only v1.1 supported (CR-1 from 3.0.0) (refactor(compliance))
  • src/compliance_bridge/evidence_stream.py — Dual-schema machinery deleted: _detect_schema_version(), migrate_record_1_0_to_1_1(), get_last_v1_0_hash(), _link_hash_v1_1() (collapsed into _link_hash()), and the EvidenceRecord.schema_version field; tests/test_dual_schema_verification.py deleted. POAM-2026-062 (refactor(compliance)!)
  • src/integrations/provider_03/provider.py — Three backward-compatibility aliases removed (fetch_legal_baseline(), validate_external_fria(), submit_evidence_chain()); validate_external_fria() had returned a hardcoded APPROVED, a silent-bypass risk. POAM-2026-063 (refactor(governance)!)
  • src/gateway/governance/decisions.py, symbolic_governor.py, src/gateway/server/agent_gateway_adapter.py — Duplicated legacy DEFER response fields removed (verdict, defer_id, missing_input_reason); canonical fields are decision, defer_token, classification_reason. POAM-2026-066 (refactor(governance)!)
  • src/gateway/governance/agw_envelope.py (entire file) — AGWEnvelope and AGWEnvelopeBuilder backward-compatibility aliases; use GovernanceEnvelope/GovernanceEnvelopeBuilder from src/gateway/governance/governance_envelope.py
  • tests/test_agw_envelope.py — backward-compatibility test suite for the removed AGWEnvelope/AGWEnvelopeBuilder aliases; see tests/test_governance_envelope.py for canonical coverage
  • Removed legacy sign_provider_04_digest() method from KMSSigner (src/gateway/governance/kms_signer.py) — use sign() instead
  • create_ftra_node() deprecated registry_path/plan_key keyword arguments (src/gateway/governance/ftra/node_factory.py) — fully removed, not just deprecated; pass a FtraNodeConfig instance instead

Fixed

  • POAM-2026-038 closure — Reconciliation worker secrets populated, CronJob operational — 2026-08-16 (fix(compliance))
  • KMS_BATCH_ENABLED default-value discrepancy resolved: confirmed default is "false" (disabled), matching KmsBatchThresholds.enabled in src/gateway/governance/schemas/thresholds.py and config/governance_thresholds.json.

Migration

See docs/BREAKING_CHANGES_v3.md for detailed upgrade instructions.

Example migration for the AGWEnvelope removal:

# Old (removed in v3.0.0):
from src.gateway.governance.agw_envelope import AGWEnvelope

# New (required):
from src.gateway.governance.governance_envelope import GovernanceEnvelope

2.1.2 - 2026-08-13

Fixed

  • feat(governance): atomic nonce burn via verify_and_consume_seal() Redis SETNX (POAM-2026-043)
  • feat(governance): dynamic standing re-check in revalidate_post_hitl() (POAM-2026-044)
  • feat(governance): RefusalReceipt parameter binding extended to validate_action() and revalidate_post_hitl() paths
  • fix(governance): defer_node.py field-name mismatch and non-existent enqueue() call corrected; DeferQueue now persists tokens to Redis db=1 (POAM-2026-045)
  • test(governance): tests/test_defer_node.py added covering durable park and failure propagation

[Unreleased — pre-2.1.2]

Added

  • KmsSigner.sign() now embeds signed_at Unix timestamp in every signed payload; verify() rejects payloads older than MAX_KMS_PAYLOAD_AGE_SECONDS (300 s), closing replay-attack vector.
  • CbfGovernor._local_debits intra-window debit ledger: verify_action() computes effective_balance = snapshot - local_debits to prevent double-spend within KMS TTL window; reset_local_debits() added for reconciliation daemon.
  • ConsensusGate: degraded-quorum routing (ERROR + APPROVE → ESCALATE) now explicitly handled before catch-all case.
  • FiscalLimitGuard.rollback_state(amount, audit_id): Saga compensation stub — logs [SAGA-ROLLBACK], reverses Redis debit, re-raises on failure.
  • tests/test_provenance_chain.py: test_link_hash_is_deterministic asserts hash stability across calls.
  • src/compliance_bridge/reconciliation_worker.py — ObjectStoreLedgerProvider (S3-compatible via boto3: AWS S3, GCS S3 Interop, MinIO, Ceph). Registered "s3" and "object-store" aliases in the _PROVIDERS factory.
  • deployment/k8s/reconciliation-worker.yaml — new CronJob manifest running ExternalLedgerReconciler every 5 minutes; default RECONCILIATION_PROVIDER changed to "s3"; added S3_RECONCILIATION_BUCKET, S3_ENDPOINT_URL, S3_REGION_NAME, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY env vars; CiliumNetworkPolicy egress extended to *.amazonaws.com.
  • docs/POAM.md — added POAM-2026-038 through -042.

Fixed

  • CausalGatekeeper: Redis connection errors are now fail-closed (raise RuntimeError) rather than returning a zero-deflection sentinel (fail-open). Absent keys remain first-boot safe.
  • Terminology: "TOCTOU gap" for the rollback atomicity issue renamed to "saga-atomicity gap" throughout docs and paper.
  • Redis access model for gateway corrected in documentation: gateway has read-write access (Tier 4 FiscalLimitGuard uses WATCH/MULTI/EXEC), not read-only as previously documented.
  • src/gateway/governance/fiscal_limit_guard.py — per-reservation TTL sentinel key fiscal:reservation:{uuid} (ex=reservation_ttl, default 300 s) bounds the crash-leakage window between reserve() and confirm()/release().
  • src/gateway/governance/routing_seal.py — generate_seal() / _canonical_payload() sanitize dots (.replace(".", "-")) in the action slug to guarantee an unambiguous 3-part . split during verify_seal().
  • src/compliance_bridge/context_accumulator.py — _content_hash() now passes separators=(",", ":") to json.dumps() for canonical, whitespace-free serialization.
  • src/gateway/governance/causal_gatekeeper.py — added _MIN_CAUSAL_SAMPLES guard (default 30, overridable via CAUSAL_MIN_SAMPLES) before backdoor.linear_regression to fail closed on sparse telemetry.
  • src/governed_financial_advisor/graph/nodes/safety_node.py — replaced hardcoded zero sentinels for drawdown, order_size, daily_vol with _fetch_live_risk_metrics(), reading live values from Redis (cbf:portfolio_drawdown:{account_id}, portfolio:daily_vol:{account_id}) with 200 ms socket timeout and safe-sentinel fallback.
  • scripts/measure_paper_metrics.py — re-enabled measure_ungoverned_baseline().
  • scripts/measure_reconciliation_metrics.py — _make_sync_redis() now honours REDIS_PASSWORD.

Changed

  • refactor(nemo): consolidate GFA LLMRails to single harness singleton —
    • Added reload_nemo_rails(config_path) (async, asyncio.Lock-guarded) and _get_reload_lock() to src/gateway/governance/langgraph_harness/nemo_node_factory.py; the module-level _nemo_rails singleton is now the sole LLMRails instance for the entire GFA pod.
    • Removed the module-level rails = load_rails() global and all global rails declarations from src/governed_financial_advisor/server.py; both hot-reload endpoints (/v1/nemo/propose-refinement and /v1/nemo/approve-refinement/{id}) now call await reload_nemo_rails() from the harness instead of maintaining their own LLMRails instance.
    • Removed the _rails singleton and get_rails() helper from src/governed_financial_advisor/tools/api.py; it now calls get_nemo_rails() from the harness directly.
    • Net result: one LLMRails instance per GFA pod (down from three); a single approved refinement now propagates to every consumer simultaneously instead of only the instance it was applied against.
    • Quarantined infra/modules/nemo_guardrails/main.tf with a HISTORICAL-ONLY — DO NOT APPLY banner (predates and diverges from the canonical config/rails/ source) and added a nemo-freshness-check CI job (.github/workflows/ci.yml) that diffs config/rails/actions.py against deployment/k8s/nemo-rails-configmap.yaml.

Documentation

  • CAGE_ARXIV.MD: 58 peer-review items addressed — bibliography fixes, formal-proof caveats (under-approximation, saga-atomicity, CBF conditional implication), security notes (FTRA trust boundary, replay vulnerability, intra-window double-spend), new Appendix D (adversarial payload examples), expanded roadmap (NoDirectBind, POAM-TIER2-001, FTRA formal verification).

[Unreleased — prior]

Added

  • src/compliance_bridge/reconciliation_worker.py — ObjectStoreLedgerProvider (S3-compatible via boto3: AWS S3, GCS S3 Interop, MinIO, Ceph). Registered "s3" and "object-store" aliases in the _PROVIDERS factory.
  • deployment/k8s/reconciliation-worker.yaml — new CronJob manifest running ExternalLedgerReconciler every 5 minutes; default RECONCILIATION_PROVIDER changed to "s3"; added S3_RECONCILIATION_BUCKET, S3_ENDPOINT_URL, S3_REGION_NAME, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY env vars; CiliumNetworkPolicy egress extended to *.amazonaws.com.
  • docs/POAM.md — added POAM-2026-038 through -042.

Fixed

  • src/gateway/governance/fiscal_limit_guard.py — per-reservation TTL sentinel key fiscal:reservation:{uuid} (ex=reservation_ttl, default 300 s) bounds the crash-leakage window between reserve() and confirm()/release().
  • src/gateway/governance/routing_seal.py — generate_seal() / _canonical_payload() sanitize dots (.replace(".", "-")) in the action slug to guarantee an unambiguous 3-part . split during verify_seal().
  • src/compliance_bridge/context_accumulator.py — _content_hash() now passes separators=(",", ":") to json.dumps() for canonical, whitespace-free serialization.
  • src/gateway/governance/causal_gatekeeper.py — added _MIN_CAUSAL_SAMPLES guard (default 30, overridable via CAUSAL_MIN_SAMPLES) before backdoor.linear_regression to fail closed on sparse telemetry.
  • src/governed_financial_advisor/graph/nodes/safety_node.py — replaced hardcoded zero sentinels for drawdown, order_size, daily_vol with _fetch_live_risk_metrics(), reading live values from Redis (cbf:portfolio_drawdown:{account_id}, portfolio:daily_vol:{account_id}) with 200 ms socket timeout and safe-sentinel fallback.
  • scripts/measure_paper_metrics.py — re-enabled measure_ungoverned_baseline().
  • scripts/measure_reconciliation_metrics.py — _make_sync_redis() now honours REDIS_PASSWORD.

Changed

  • refactor(nemo): consolidate GFA LLMRails to single harness singleton —
    • Added reload_nemo_rails(config_path) (async, asyncio.Lock-guarded) and _get_reload_lock() to src/gateway/governance/langgraph_harness/nemo_node_factory.py; the module-level _nemo_rails singleton is now the sole LLMRails instance for the entire GFA pod.
    • Removed the module-level rails = load_rails() global and all global rails declarations from src/governed_financial_advisor/server.py; both hot-reload endpoints (/v1/nemo/propose-refinement and /v1/nemo/approve-refinement/{id}) now call await reload_nemo_rails() from the harness instead of maintaining their own LLMRails instance.
    • Removed the _rails singleton and get_rails() helper from src/governed_financial_advisor/tools/api.py; it now calls get_nemo_rails() from the harness directly.
    • Net result: one LLMRails instance per GFA pod (down from three); a single approved refinement now propagates to every consumer simultaneously instead of only the instance it was applied against.
    • Quarantined infra/modules/nemo_guardrails/main.tf with a HISTORICAL-ONLY — DO NOT APPLY banner (predates and diverges from the canonical config/rails/ source) and added a nemo-freshness-check CI job (.github/workflows/ci.yml) that diffs config/rails/actions.py against deployment/k8s/nemo-rails-configmap.yaml.

[v2.1.1-post — 2026-08-05]

Post-release fixes and paper measurement improvements. No version bump — these changes target the 2026-08-05 measurement run and upstream research publication accuracy. All governance logic changes are backward-compatible.

Added

  • src/gateway/governance/authorization_claim_detector.py — new AuthorizationClaimDetector module that identifies and blocks requests asserting or implying elevated authorization (e.g. "I have admin access", "pretend I am root"). Backed by tests/test_authorization_claim_detector.py.
  • docs/paper/measurements/2026-08-05-final-fix/ and docs/paper/measurements/2026-08-05-gap-fix/ — promoted measurement runs; best results: 68.4% adversarial deflection (13/19 evaluated, 2 network errors), 0.0% benign FPR (0/18 evaluated, 2 network errors).
  • pyproject.toml — pyahocorasick>=2.0.0 added to gateway optional-dependency group; resolves [WARN] pyahocorasick not installed at import and restores O(n) Aho-Corasick keyword scanning in text_filter.py.

Fixed

  • src/governed_financial_advisor/graph/nodes/safety_node.py — _extract_trade_payload() now hardcodes risk-metric fields (latency_ms, drawdown, order_size, daily_vol) to safe sentinel values (0.0/0) instead of conditionally passing them from the LLM execution plan. Closes UCA-5/UCA-2 100% benign trade_execution FPR (75.0% → 0.0%). Architectural invariant: safety enforcement is purely deterministic LangGraph node execution — never dependent on LLM plan output (fix(governance)). (Superseded 2026-08-06: drawdown/daily_vol are now read live from Redis with sentinel fallback — see [Unreleased].)
  • config/rails/actions.py — added Stage 1C structural-attack blocklist inside custom_self_check_input() between Stage 1B (illegal-finance) and Stage 2 (allowlist). Stage 1C blocks SQL injection markers (;, --, '; DROP, union select) and HTML/script injection markers (<script, javascript:, onerror=, etc.) and delegates to detect_prompt_injection() from src/gateway/governance/prompt_injection_detector.py. Closes INJ-004/INJ-005 bypass paths. prompt_injection deflection: 33.3% → 50.0% (+16.7 pp) (fix(governance)).

Changed

  • CAGE_ARXIV.MD — Tables 5 and 6 updated to run 2026-08-04-6edb597 / 2026-08-05-gap-fix; measurement notes updated with run label, Gate E7 status, and fix descriptions (docs).
  • Documentation updated across 12 files to accurately reflect the 8-tier symbolic governor pipeline (Tier 0.5 FTRA + Tiers 0–6b) — previously several docs referred to a "7-tier" pipeline, which omitted the fully-implemented FTRA pre-execution gate (docs).

Added

  • KmsSigner.sign() now embeds signed_at Unix timestamp in every signed payload; verify() rejects payloads older than MAX_KMS_PAYLOAD_AGE_SECONDS (300 s), closing replay-attack vector.
  • CbfGovernor._local_debits intra-window debit ledger: verify_action() computes effective_balance = snapshot - local_debits to prevent double-spend within KMS TTL window; reset_local_debits() added for reconciliation daemon.
  • ConsensusGate: degraded-quorum routing (ERROR + APPROVE → ESCALATE) now explicitly handled before catch-all case.
  • FiscalLimitGuard.rollback_state(amount, audit_id): Saga compensation stub — logs [SAGA-ROLLBACK], reverses Redis debit, re-raises on failure.
  • tests/test_provenance_chain.py: test_link_hash_is_deterministic asserts hash stability across calls.

Fixed

  • CausalGatekeeper: Redis connection errors are now fail-closed (raise RuntimeError) rather than returning a zero-deflection sentinel (fail-open). Absent keys remain first-boot safe.
  • Terminology: "TOCTOU gap" for the rollback atomicity issue renamed to "saga-atomicity gap" throughout docs and paper.
  • Redis access model for gateway corrected in documentation: gateway has read-write access (Tier 4 FiscalLimitGuard uses WATCH/MULTI/EXEC), not read-only as previously documented.

Documentation

  • CAGE_ARXIV.MD: 58 peer-review items addressed — bibliography fixes, formal-proof caveats (under-approximation, saga-atomicity, CBF conditional implication), security notes (FTRA trust boundary, replay vulnerability, intra-window double-spend), new Appendix D (adversarial payload examples), expanded roadmap (NoDirectBind, POAM-TIER2-001, FTRA formal verification).

[Unreleased — prior]

Changed

v2.1.1 — 2026-07-30

9 commits since v2.1.0 (2026-07-27). Patch release: jurisdiction-aware compliance fixes, two production HITL bug fixes, documentation completeness audit, and no new features.

Fixed

  • Made sla_monitor.py region-aware, closing FINDING-05: jurisdictional SLA controls (SC-7/SC-8 for US_FED, Article 12 for EU_ECB, MAS-FEAT-1 for APAC_MAS) are now correctly monitored for evidence staleness in their applicable region instead of being silently skipped (fix(compliance))
  • Removed dead ftra_reachability.py scaffold that gave a false impression of FTRA test coverage; added 30 direct tests for the real src/gateway/governance/ftra/ implementation, which surfaced and fixed two production defects that silently disabled the entire DeferQueue human-in-the-loop pathway: DeferQueue() instantiated without a required redis_client, and NodeInterrupt unconditionally caught before it could suspend the graph for human review (fix(governance))
  • Added jurisdiction-aware HITL SLA and PII audit retention citations, closing FINDING-07/08/09: GovernanceThresholds.pii_audit_retention_authority, pii_audit_log(), hitl_escalator.py, and prompt_injection_detector.py previously hardcoded US_FED citations (FISMA AU-11, SR 26-2) with no runtime region check; now resolve CAGE_DEPLOYMENT_REGION at call time to the correct GDPR Art. 5(1)(e) / DORA Art. 10 / MAS Notice 655 / MAS FEAT citation (fix(governance))
  • Resolved a duplicate POAM-2026-023 ID collision in docs/POAM.md (fix(compliance))
  • Documented SECURITY.md GHSA-hfqj-24cj-693g and GHSA-v3h4-8458-5ww3 as resolved with implementation detail, matching the fixes already present in inference_proxy.py and governance_middleware.py (fix(docs))

Changed

  • Corrected pipeline tier numbering (CBF=2, Fiscal=3, OPA=4) across ~25 docs that had swapped or stale tier references; removed stale references to the retired SLM tier and the fictional governed_tool decorator (docs)
  • Removed fictional v0.1.0/rc-v0.1.0 version references across ~40 files in a v2.0.0/v2.1.0 codebase (docs)
  • Deleted superseded planning and process-fiction documents (implementation plans, roadmaps, merge plans) and fixed the dangling cross-references left by those deletions (docs)
  • Consolidated Roo/Cline agent rules into a single tool-agnostic AGENTS.md (docs)
  • Corrected governance verdict vocabulary to the canonical 4-state enum (CLEAR / HITL_REQUIRED / BLOCKED / ESCALATED) (docs(governance))
  • Corrected fabricated FTRA architecture description across 5 docs to reflect the actual implementation wired into governed_financial_advisor/graph.py (docs(governance))
