feat: network-policy extension, governance lifecycle, audit remediation

- Network-policy SPIRE plugin extension
- Governance event notification with merkle anchoring
- Shellstream specs for consent channels + HFL embedded ABI
- All 17 audit findings from AUDIT.md remediated
- SSH credential composer + substrate key manager updates
- Test coverage for config + sshcert packages

+# CLAUDE.md — Guildhouse SPIRE Plugins
+
+## Project Identity
+
+Go plugins for [SPIRE](https://spiffe.io/docs/latest/spire-about/) that integrate SPIFFE identity with Guildhouse governance. Four plugins: OIDC workload attestation, SSH credential composition with Shellstream extensions, governance event notification with merkle anchoring, and substrate-aware key management.
+
+## Development Environment
+
+**No Go toolchain on host.** All build/test/lint commands run inside containers.
+
+```bash
+# Build
+podman run --rm -v .:/workspace:Z -w /workspace golang:1.24 go build ./...
+
+# Test

+## Key Constraints
+
+- **grpc v1.58.3** pinned for compatibility with hashicorp/go-plugin v1.6.3
+- Proto generation uses protoc-gen-go-grpc **v1.3.0** (not latest) for grpc v1.58 compat
+- Proto files in `proto/` are copies from guildhouse monorepo — do not edit here
+- Plugin binaries use hashicorp/go-plugin GRPCPlugin interface for SPIRE registration
+
+## Related Repos
+
+- `guildhouse/` — Platform monorepo (Quartermaster, Bascule services)
+- `guildhouse-proto/` — Canonical proto definitions
+- `substrate/` — OS platform, Shellstream canonical Rust impl

+
+OIDC tokens may contain custom claims (e.g., `tenant_id`, `roles`) that are populated by the identity provider's protocol mappers. **These claims MUST NOT be trusted for authorization without server-side verification.** In self-managed Keycloak deployments, users can modify their own protocol mappers to inject arbitrary values into custom claims.

+The `tenant_id` claim in particular MUST be cross-referenced against the server-side tenant registry. The plugin SHOULD derive tenant identity from the SPIRE registration entry or a trusted server-side mapping, not solely from the OIDC token's `tenant_id` claim.

+**Post-hoc approval expiry:** If post-hoc approval is not obtained within the configured `post_hoc_approval_window_hours` (default: 24 hours), the GovernanceService MUST:
+
+1. Emit an escalation alert at severity `CRITICAL` to the configured `escalation_channel`.
+2. Mark the intent as `post_hoc_expired` in the audit trail.
+3. Trigger automatic credential revocation for the credential issued under the break-glass event, unless the credential has already expired naturally.

+Implementations MUST NOT allow break-glass credentials to persist indefinitely without retrospective approval. The automatic revocation ensures that emergency credentials have a bounded lifetime of accountability.

 **Rationale:** Security incidents cannot wait for approval flows. The break-glass mechanism balances immediate response with accountability by requiring after-the-fact justification.
