Dynamic inventory plugin — queries Bastion for managed devices,
groups by OS and compliance state, bastion_* host vars, zero
credentials in inventory.
Credential lookup plugin — resolves short-lived credentials from
Bastion's CredentialResolver at execution time. Graceful
degradation when broker unavailable.
Chronicle callback plugin — reports playbook lifecycle events
(started, task completed, completed) to Chronicle. Optionally
triggers compliance re-evaluation after playbook completion.
Shared BastionClient for all plugins using stdlib urllib.

bastion.toml manifest parser with variable validation and dependency
declarations. Declarative compliance policy schema with per-platform
check implementations. Template loader with variable substitution
(Bastion-owned files only — never touches Ansible/Terraform).
PolicyRegistry and AccordRegistry with builtin fallbacks.
BOUNDARY: loader never touches automation framework files.

C-1: Keycloak driver now verifies JWT signatures via JWKS.
Forged tokens are rejected. Previously any base64 JWT was accepted.
C-2: on_behalf_of requires gsap:impersonate role in JWT claims.
C-3: Entra driver denies on JWKS failure (no unverified fallback).
H-10: JWKS cache refreshes on kid miss for key rotation.
Shared JWKSVerifier used by both drivers. alg=none blocked.
iss, aud, exp validated for all tokens.

MCP tools for list_devices, get_device_compliance, sync_device,
remote_lock. All route through governed IntuneConnector
invocation with Chronicle audit.

AC issuance can now require device compliance via Intune.
Configurable per-accord and globally. Disabled by default
for backward compatibility. Emits DEVICE_COMPLIANCE_CHECKED
Chronicle event. Adds device_id, device_compliant, and
compliance_checked_at fields to AuthorizationContext.

Implements ConnectorPlugin for Intune Graph API operations.
Governed invocation: every Intune call requires an active AC
and emits a Chronicle CONNECTOR_INVOKED event.
Operations: list, get, compliance check, sync, lock, retire, wipe.
In-memory compliance cache with configurable TTL.
Conditional registration via intune_enabled setting.

Validates Entra JWTs directly via JWKS verification.
Extracts device_id for compliance gating, MFA status,
roles, and constructs DID from Entra tenant + oid.
Adds device_id field to AuthResult dataclass.

Reference implementation of GCAP-SPEC-SHELLBOUND-BROKER-0001
in FastAPI. Designed for ISVs and enterprises implementing
the governed shell authorization protocol.
Architecture:
FastAPI + SQLModel + Pydantic + async SQLite
Single container deployment: Dockerfile included
OpenAPI schema at /docs is the machine-readable GSAP contract
Broker Interface (§5):
POST /governance/authorize/ — Issue AC
GET /governance/authorize/{p}/ — Poll elevation
POST /governance/complete/ — Receive CR
GET /governance/session/{id}/ — View chain of custody
POST /governance/elevate/ — JIT elevation
GET /governance/drivers/ — List drivers
Identity Driver Interface (§2.2):
IdentityDriver — abstract base (ISV extension point)
KeycloakDriver — Keycloak implementation
DriverRegistry — driver lookup and registration
Chronicle integration (§1.4):
Optional CloudEvents emission via CHRONICLE_WEBHOOK_URL
Forgejo push event format for receiver compatibility
Models:
Pydantic schemas for AC, CR, Principal, Accord, Operation
SQLModel DB models for persistence
Tests: 6 async tests including full AC→CR cycle
695 lines across 27 files.
