Subject: [PATCH 01/24] add config file support and standalone redis for local
 dev

- Add config.toml with encrypted_keyfile backend (DevelopmentSigningBackend)
- Add verifier-config.toml with same setup, require_dpop=false for demo
- Add standalone redis service on port 6380 to docker-compose (separate from cluster)
- Update registry and verifier config.rs to load optional config file before env vars
- Improve dev.sh postgres wait logic using pg_isready instead of fixed sleep
- Add sqlx migrate run to dev.sh startup sequence

Subject: [PATCH 02/24] ensure audit_events partition exists on registry
 startup

Create current month's audit partition if it doesn't exist, catching
42P07 (already exists) error. Handles date-shifted environments where
base migration partitions (2025-01/02) would cause audit writes to fail.

Subject: [PATCH 04/24] bridge grant api contract between backend and ui

Update GrantResponse to include ui-expected fields:
- grant_id (alias for id)
- agent_name, service_provider_name (from joined tables)
- requested_capabilities, requested_envelope (aliases for consistency)
- created_at from issued_at

Extend GrantRow with agent_name and service_provider_name from joins.
Add get_grant_row() helper and update queries with proper table joins.

Subject: [PATCH 05/24] implement agent list and detail endpoints with grants

Add GET /v1/agents list endpoint returning AgentSummary objects.
Refactor get_agent() to fetch full agent details with nested grants.
Add AgentResponse matching ui's AgentDetails type.
Add GrantSummaryResponse for grants within agent details.
Add AgentSummaryResponse for list endpoint.
Add database queries: list_agents, count_active_grants, list_grants_for_agent.

Subject: [PATCH 06/24] fix ui capability types and grant status handling

Change Capability type from uppercase ('Read', 'Write') to lowercase
('read', 'write', 'transact', 'delete', 'custom') matching rust serde.
Update capabilities.ts switch statements to use lowercase types.
Widen GrantSummary.status from union type to string for backend compatibility.
Fix all tests to use lowercase capability types.

Subject: [PATCH 07/24] implement demo-mode approval and agent registration
 script

Update approval-ui api.ts:
- Change REGISTRY_URL from process.env to hardcoded http://localhost:8080
- Update approveGrant() signature to send approved_by, approval_nonce, approval_signature

Update ApprovalPage.tsx:
- Remove WebAuthn imports
- Implement demo-mode approval generating random nonce and 64-byte hex signature
- Use fixed demo user UUID for approved_by

Add register-demo-agent.py script:
- Generate Ed25519 keypairs using PyNaCl
- Build signed manifests with canonical JSON matching rust serde_json
- Seed human principal and service providers directly via psql
- Create pending grant request visible in approval ui

Subject: [PATCH 08/24] handle grant status mapping in agent activity page

Add grantStatus mapping Record for all backend grant statuses:
- approved (green)
- pending (yellow)
- denied (red)
- revoked (gray)
- expired (gray)

Add fallback handling for unknown statuses with default styling.
Update status display logic to use mapping instead of assuming active/revoked/expired.

Subject: [PATCH 12/24] fix SDK token issue mismatch

- make IssueTokenRequest fields optional (agent_id, service_provider_id, etc)
- look up grant details from DB when simplified request (grant_id only) received
- add dpop_thumbprint field for SDK compatibility
- add GrantNotApproved error variant (409 CONFLICT)
- add access_token and token_type fields to TokenResponse for SDK

Subject: [PATCH 13/24] create demo agent binary

- new services/demo-agent with full agent registration and grant flow
- embedded mock service provider on port 9090
- demonstrates capability enforcement: 3 allowed, 1 denied
- uses deterministic Ed25519 keypair from demo seed
- add demo-agent to workspace members

Subject: [PATCH 14/24] add Dashboard tab to approval UI with Grafana embedding

- new DashboardPage.tsx with Grafana iframe in kiosk mode
- two tabs: token verification SLO and circuit breakers
- graceful error state when Grafana unreachable
- wire up /dashboard route in App.tsx and server.ts
- add Grafana embedding env vars to docker-compose (GF_SECURITY_ALLOW_EMBEDDING, GF_AUTH_ANONYMOUS_ENABLED)

Subject: [PATCH 15/24] integrate demo agent into dev.sh and remove old
 bootstrap script

- add demo-agent to cargo build and start in dev.sh
- 5s delay before starting demo agent to allow registry readiness
- update service status display with mock service and Grafana URLs
- delete scripts/register-demo-agent.py (replaced by built-in demo agent)

Subject: [PATCH 16/24] fix SDK compatibility in registry handlers

- accept base64url-encoded signatures (SignedManifest format) in addition to hex
- add serde aliases for grant request fields (requested_capabilities, requested_envelope)
- allows SDK and demo agent to successfully register and request grants
