fix(security): address review feedback on cross-channel approval checks

1. thread_ops.rs: Remove .or(Some(&*message.channel)) fallback in maybe_hydrate_thread() so that when source_channel is NULL in the DB, it stays None rather than being stamped with the requesting channel. This preserves the fail-closed behavior of is_approval_authorized(). 2. libsql_migrations.rs: Remove source_channel from base SCHEMA to eliminate duplicate column definition. The column is now added solely by V14 migration, preventing fresh databases from failing on startup. 3. wasm/setup.rs: Expand RESERVED_CHANNEL_NAMES to cover all built-in channels (http, signal, slack-relay, secret_save) and add a dynamic collision check against already-registered channel names passed from the startup sequence.

+# User Management API
+
+DB-backed user management for multi-tenant IronClaw deployments. Covers admin user CRUD, per-user secrets provisioning, self-service profile, API token management, and usage reporting.
+
+## Authentication
+
+All endpoints require `Authorization: Bearer <token>`. Tokens are either:
+- **Env-var tokens** — configured via `GATEWAY_AUTH_TOKEN` (single-user) at startup
+- **DB-backed tokens** — created via `POST /api/tokens` or `POST /api/admin/users`
+
+DB tokens are SHA-256 hashed at rest; plaintext is returned exactly once at creation time.
+
+Auth is cached in a bounded LRU (1024 entries, 60s TTL). Suspending a user or revoking a token may take up to 60s to take effect.
+
+## Roles
+
+| Role | Scope |
+|------|-------|
+| `admin` | Full access to all endpoints |
+| `member` | Self-service profile + own token management only |
+
+Endpoints marked **Admin** return `403 Forbidden` for `member` role.
+
+---
+
+## Admin: Users
+
+### POST /api/admin/users
+
+Create a new user. Returns the user record and a one-time plaintext API token.
+
+**Auth:** Admin
+
+**Request body:**
+
+```json
+{
+  "display_name": "Alice Smith",
+  "email": "[email protected]",
+  "role": "member"
+}
+```
+
+| Field | Type | Required | Default | Notes |
+|-------|------|----------|---------|-------|
+| `display_name` | string | yes | | |
+| `email` | string | no | `null` | Must be unique if provided |
+| `role` | string | no | `"member"` | `"admin"` or `"member"` |
+
+**Response:** `200 OK`
+
+```json
+{
+  "id": "550e8400-e29b-41d4-a716-446655440000",
+  "email": "[email protected]",
+  "display_name": "Alice Smith",
+  "status": "active",
+  "role": "member",
+  "token": "a1b2c3d4e5f6...64-char hex...",
+  "created_at": "2026-03-25T12:00:00+00:00",
+  "created_by": "admin-user-id"
+}
+```
+
+The `token` field is the plaintext API token. It is shown **only once** — store it securely.
+
+**Errors:** `400` (missing display_name, invalid role), `403` (not admin), `503` (no database)
+
+---
+
+### GET /api/admin/users
+
+List all users.
+
+**Auth:** Admin
+
+**Response:** `200 OK`

+
+### GET /api/admin/users/{id}
+
+Get a single user by ID.
+
+**Auth:** Admin

+  "created_by": "admin-user-id",
+  "metadata": {}
+}
+```
+
+**Errors:** `404` (user not found), `403` (not admin)
+
+---
+
+### PATCH /api/admin/users/{id}
+
+Update a user's display name and/or metadata. Omitted fields are left unchanged.
+
+**Auth:** Admin
+
+**Request body:**
+
+```json
+{
+  "display_name": "Alice Johnson",
+  "metadata": {"department": "engineering"}
+}
+```
+
+| Field | Type | Required | Notes |
+|-------|------|----------|-------|
+| `display_name` | string | no | |
+| `role` | string | no | `"admin"` or `"member"` |
+| `metadata` | object | no | Replaces entire metadata object (full replacement; keys not included are removed) |
+
+**Response:** `200 OK` — returns the full updated user record (same shape as GET detail, without `last_login_at`/`created_by`).
+
+**Errors:** `404` (user not found), `403` (not admin)
+
+---
+
+### POST /api/admin/users/{id}/suspend
+
+Suspend a user. Suspended users cannot authenticate (DB auth checks user status).
+
+**Auth:** Admin
+
+**Response:** `200 OK`
+
+```json
+{
+  "id": "550e8400-...",
+  "status": "suspended"
+}
+```
+
+**Errors:** `404` (user not found), `403` (not admin)
+
+---
+
+### POST /api/admin/users/{id}/activate
+
+Re-activate a suspended user.
+
+**Auth:** Admin
+
+**Response:** `200 OK`
+
+```json
+{
+  "id": "550e8400-...",
+  "status": "active"
+}
+```
+
+**Errors:** `404` (user not found), `403` (not admin)
+
+---
+
+### DELETE /api/admin/users/{id}
+
+Permanently delete a user and all associated data (tokens, jobs, conversations, memory, routines, settings, secrets).
+
+**Auth:** Admin
+
+**Response:** `200 OK`
+
+```json
+{
+  "id": "550e8400-...",
+  "deleted": true
+}
+```
+
+**Errors:** `404` (user not found), `403` (not admin)
+
+**Cascade:** Deletes from `api_tokens`, `agent_jobs`, `conversations`, `memory_documents`, `routines`, `secrets`, `settings`, `wasm_tools`, and related tables. On PostgreSQL this uses FK cascades; on libSQL it uses explicit deletes.
+
+---
+
+## Admin: Per-User Secrets
+
+Provision secrets on behalf of individual users. The primary use case is an application backend (acting as admin) that configures per-user credentials so each user's IronClaw agent can call back to external services.
+
+Secrets are encrypted at rest with AES-256-GCM using a per-secret HKDF-derived key. Plaintext values are **never returned** by any endpoint — they can only be used by the agent's tool system at runtime.
+
+### PUT /api/admin/users/{user_id}/secrets/{name}
+
+Create or update a secret for the specified user. If a secret with the same name already exists, it is overwritten.
+
+**Auth:** Admin
+
+**Path parameters:**
+
+| Param | Type | Notes |
+|-------|------|-------|
+| `user_id` | string | The user's ID |
+| `name` | string | Secret name (normalized to lowercase) |
+
+**Request body:**
+
+```json
+{
+  "value": "sk-live-abc123...",
+  "provider": "my-app-backend",
+  "expires_in_days": 90
+}
+```
+
+| Field | Type | Required | Notes |
+|-------|------|----------|-------|
+| `value` | string | yes | The secret value (encrypted at rest, never returned) |
+| `provider` | string | no | Tag for grouping (e.g. `"stripe"`, `"my-app"`) |
+| `expires_in_days` | integer | no | Auto-expire after N days; `null` = never |
+
+**Response:** `200 OK`
+
+```json
+{
+  "user_id": "550e8400-...",
+  "name": "my_app_callback_token",
+  "status": "created"
+}
+```
+
+**Errors:** `400` (missing value), `403` (not admin), `503` (secrets store not available)
+
+**Example — application backend provisioning a callback token:**
+
+```bash
+# Admin creates a user
+curl -X POST https://ironclaw.example.com/api/admin/users \
+  -H "Authorization: Bearer $ADMIN_TOKEN" \
+  -d '{"display_name": "Alice", "role": "member"}'
+# Response includes: {"id": "alice-uuid", "token": "alice-bearer-token", ...}
+
+# Admin provisions a per-user callback secret
+curl -X PUT https://ironclaw.example.com/api/admin/users/alice-uuid/secrets/app_callback_token \
+  -H "Authorization: Bearer $ADMIN_TOKEN" \
+  -d '{"value": "per-user-jwt-for-alice", "provider": "my-app"}'
+
+# Now Alice's IronClaw agent can use the "app_callback_token" secret
+# when calling tools that need to authenticate back to the app backend.
+```
+
+---
+
+### GET /api/admin/users/{user_id}/secrets
+
+List a user's secrets. Returns names and providers only — **never values or hashes**.
+
+**Auth:** Admin
+
+**Response:** `200 OK`
+
+```json
+{
+  "user_id": "550e8400-...",

+    {"name": "openai_api_key", "provider": "openai"}
+  ]
+}
+```
+
+---
+
+### DELETE /api/admin/users/{user_id}/secrets/{name}
+
+Delete a specific secret for a user.
+
+**Auth:** Admin
+
+**Response:** `200 OK`
+
+```json
+{
+  "user_id": "550e8400-...",

+---
+
+### DELETE /api/tokens/{id}
+
+Revoke one of the authenticated user's tokens. Users can only revoke their own tokens.
+
+**Auth:** Any authenticated user
+
+**Path:** `id` — UUID of the token to revoke
+
+**Response:** `200 OK`
+
+```json
+{
+  "status": "revoked",
+  "id": "token-uuid"
+}
+```
+
+**Errors:** `400` (invalid UUID), `404` (token not found or belongs to another user)
+
+---
+
+## Error Format
+
+All error responses return a plain text body with the error message and the corresponding HTTP status code:
+
+| Code | Meaning |
+|------|---------|
+| `400` | Bad request (missing fields, invalid input) |
+| `401` | Missing or invalid bearer token |
+| `403` | Authenticated but insufficient role (member accessing admin endpoint) |
+| `404` | Resource not found |
+| `503` | Database or secrets store not available |
+| `500` | Internal server error |
+
+---
+
+## Security Model
+
+### Secrets Encryption
+
+- **Algorithm:** AES-256-GCM with per-secret HKDF-SHA256 derived keys
+- **Master key:** 32+ bytes, resolved from `SECRETS_MASTER_KEY` env var or OS keychain
+- **Storage format:** `nonce (12B) || ciphertext || tag (16B)` in `encrypted_value` column
+- **Per-secret salt:** 32 random bytes stored alongside the ciphertext
+- **Zero-exposure:** Plaintext never appears in logs, debug output, API responses, or LLM conversations
+
+### Auth Cache
+
+- Bounded LRU cache (1024 entries max)
+- 60-second TTL per entry
+- Suspending a user or revoking a token takes up to 60s to propagate
+
+---
