style: cargo fmt across Phase 3.5 changes

Pure formatting pass — no behavior changes. Catches the line-wrapping
drift across the new authz / api_keys / middleware / handler edits
that piled up during the implementation.

-**Current focus (Phase 3, pre-v1.1):** admin auth gate, then multi-app scoping. The latter introduces `apps` as the top-level isolation boundary for scripts, routes, domains, and (later) data. See blueprint §11.5 for the design. Every v1.1+ feature must assume `app_id` exists as a scoping dimension.
+**Current focus (Phase 4, v1.1):** data-plane SDKs — KV store, then document store, then HTTP client, then cron triggers. See blueprint §12. Phase 3 (admin auth + multi-app scoping) shipped; every v1.1+ table starts with `app_id UUID NOT NULL REFERENCES apps(id) ON DELETE CASCADE` and every Rhai SDK call resolves its app from the execution context.

+//! checks: none — every authenticated user manages **their own** keys.
+//! The repo enforces caller ownership on `delete`, and `list` is
+//! scoped to the caller's user_id. No instance-level authority is
+//! exposed (no listing other users' keys, no admin-issued keys for

+//! Mint semantics:
+//!   * raw token is returned **exactly once** in the POST response and
+//!     never logged. Lose it = mint a new key.
+//!   * `app_id` (optional) binds the key to one app; capability checks
+//!     deny every `App*(other_app)`.
+//!   * scopes containing `instance:*` are rejected when `app_id` is

+//! Single entry point for every admin endpoint: `can(repo, principal,
+//! capability)` returns whether the caller can perform the action.

+//! after loading the resource so the capability binds to the resource's
+//! actual `app_id`, not a path param the caller controls.
+//!
+//! Three layers of intersection, evaluated in order:
+//!
+//!   1. **Role grant** — does the caller's `InstanceRole` plus any
+//!      `app_members` row authorize this capability?
+//!   2. **Scope intersection** — if the principal came from an API key
+//!      (`principal.scopes.is_some()`), does the key's scope set cover
+//!      the capability's required scope?
+//!   3. **App binding** — if the key was minted bound to a specific
+//!      app (`principal.app_binding`), does the capability target the
+//!      same app? (Instance-level capabilities are denied for bound
+//!      keys; the mint handler also rejects the combination upfront.)
+//!
+//! The capability set is intentionally finer-grained than the seven
+//! scopes (e.g., `AppWriteScript` vs `AppWriteRoute` both fall under
+//! the `script:write` / `route:write` scopes respectively). Keeping
+//! capabilities precise lets a `script:write`-only key write scripts

+//! Phase 3.5 authorization end-to-end tests.
+//!
+//! Covers the 11 scenarios from `lay-foundations-for-snazzy-truffle.md`
+//! step 9:
+//!
+//!  1. Bootstrap admin promotes to owner.
+//!  2. Owner access matrix on a sample app.
+//!  3. Admin access matrix.
+//!  4. Member access matrix.
+//!  5. Bearer (pic_) + cookie produce the same Principal.
+//!  6. Scope intersection: a script:read-only key cannot write.
+//!  7. Bound key cannot escape its app.
+//!  8. Member listing isolation (apps + scripts).
+//!  9. Deactivation revokes API keys.
+//! 10. Mint rejects bound key with `instance:*` scope.
+//! 11. `list_active_owners` returns the expected set under the seed
+//!     that the startup warning is built from (we don't capture the
+//!     log line itself — the data source is the testable surface).
+//!
+//! Same harness as `tests/api.rs`: `#[sqlx::test]` against a real
+//! Postgres, `TestServer` over the in-process app. We do NOT bake a
+//! token into the default headers here — each test wires its own
+//! credential per request to exercise the cookie / Bearer split.

+## 11.5 App Scoping (Phase 3b) — Shipped

+- `crates/shared/src/{app,ids,script,route}.rs` — `App`, `AppDomain`, `AppId`, `app_id` fields on `Script`/`Route`/`ExecutionLog`.
+- `crates/manager-core/src/{app_repo,app_domain_repo,apps_api,app_bootstrap}.rs` — repos + admin API + Hello-World seed.
+- `crates/orchestrator-core/src/routing/{app_domains,pattern,table}.rs` — `AppDomainTable`, `parse_app_domain`, per-app `RouteTable`.
+- Migration `0005_apps.sql`.
+
+**Deviations from the design below**: none of substance. Two operational notes:
+- The Hello-World seed lives in `crates/manager-core/seeds/hello.rhai` and is inserted by a Rust bootstrap step (`seed_hello_world_if_fresh`) rather than from the migration — keeps it testable and gives the dashboard editor real source to render. The migration always inserts the `default` app + `localhost` claim; the seed only fires when that app is otherwise empty.
+- Per-app admin roles/permissions are deferred — every authenticated admin can act on every app. The middleware seam (`auth_middleware::require_admin`) is the place where role checks slot in later.
 
 **Purpose**: PiCloud hosts multiple independent applications on one platform. Each app is the isolation boundary for scripts, routes, domains, and (later) data — App A cannot see or modify App B's resources except through HTTP calls between them.

+## 11.6 Users, roles, and bearer-token auth (Phase 3.5) — Pending
+
+**Status**: pending. Targets `crates/manager-core/src/{authz,api_keys_api,api_key_repo}.rs`, an extended `auth_middleware.rs`, new shared types under `crates/shared/src/auth.rs`, migration `0006_users_authz.sql`.
+
+**Purpose**: bridge Phase 3b → Phase 4. Phase 4's v1.1 SDKs (KV, docs, HTTP, cron) each gate access on the calling principal. Without a real authorization model in place, every SDK addition has to either invent its own gate or stay open. Phase 3.5 lands `can(principal, capability)` as the single check every future SDK + admin endpoint goes through, so v1.1 work focuses on data plane shape, not on re-litigating auth.
+
+**Why this slot**: same logic as Phase 3b. Adding a `Principal` parameter and a capability check to surfaces that don't exist yet is free; retrofitting them onto live SDK services after v1.1 ships is a refactor of every gate.
+
+### Principal Model
+
+One `Principal` value represents a human admin user. Service accounts (CI bots, Rhai scripts calling out) get **schema room** in this phase but no runtime support — `users.kind` style differentiation lands when Phase 4's `users.*` SDK arrives. Until then, every authenticated request resolves to exactly one admin row, whether the credential is a session cookie or a bearer API key.
+
+```rust
+pub struct Principal {
+    pub user_id:       UserId,             // alias of AdminUserId for the transition
+    pub instance_role: InstanceRole,
+    pub scopes:        Option<Vec<Scope>>, // None = cookie session (full role authority)
+                                           // Some = API key (intersect with role)
+    pub app_binding:   Option<AppId>,      // API key bound to one app; denies other apps
+}
+```
+
+### Instance Roles (one per user)
+
+| Role | Powers |
+|---|---|
+| `owner` | full instance control, manage other owners, implicit `app_admin` on every app. Multiple owners allowed. |
+| `admin` | create apps, invite users, implicit `editor` on every app. Cannot manage instance-wide settings or other owners. |
+| `member` | invited into specific apps only. Cannot create apps, cannot invite. **Strict isolation enforced at SQL** — list endpoints `WHERE app_id IN (SELECT app_id FROM app_members WHERE user_id = $1)`; the API never returns apps a member isn't part of. |
+
+The current Phase 3a `admin_users` rows all become `owner` via `DEFAULT 'owner'` on the new column. Multi-owner installs get a startup `tracing::warn!` listing the active owner usernames so the operator can demote extras via `PATCH /api/v1/admin/admins/{id}`.
+
+### App-Scoped Roles (zero-to-many per user × app)
+
+| Role | Grants |
+|---|---|
+| `app_admin` | settings, domain claims, delete app |
+| `editor` | CRUD on scripts, routes, sandbox config |
+| `viewer` | read scripts + execution logs |
+
+Implicit grants from instance role: every `owner` is `app_admin` on every app; every `admin` is `editor` on every app. Explicit `app_members` rows are the only path for `member` users.
+
+### Auth Methods — Same Principal, Different Extractor
+
+Two credential types feed the same middleware:
+
+1. **Session cookie** (Phase 3a, unchanged) — `picloud_session=<token>`. Extracted by header or cookie. SHA-256 lookup against `admin_sessions.token_hash`. Sliding 24h TTL. Produces `Principal { scopes: None, app_binding: None }`.
+
+2. **Bearer API key** (new) — `Authorization: Bearer pic_<base32(32 random bytes)>`. The `pic_` prefix is the discriminator: present → API key path; absent → session path. The 8 chars immediately after `pic_` are indexed (`api_keys.prefix`); the full body after `pic_` is Argon2id-verified against each candidate's `hash`. Last-used timestamp updates inline.
+
+Both paths converge on the same `Principal` extension; handlers cannot tell which credential was presented unless they introspect `principal.scopes`.
+
+### API Key Format & Storage
+
+- Raw form: `pic_<base32(32 random bytes, no padding)>` — ~56 chars total.
+- Stored: 8-char prefix + Argon2id PHC hash of the body. Raw value returned **exactly once** in the `POST /api/v1/admin/api-keys` response; never logged, never readable again.
+- Optional `expires_at`. Lookup queries always filter `expires_at IS NULL OR expires_at > NOW()`.
+- Optional `app_id` ("bound key") — every `App*(other_app)` capability is denied for this key, regardless of the user's role.
+
+### Scope Set (intentionally narrow)
+
+Exactly seven scopes; no further subdivision until a real use case appears:
+
+`script:read`, `script:write`, `route:write`, `domain:manage`, `log:read`, `app:admin`, `instance:admin`
+
+Mint-time validation rejects unknown values. Bound keys (`app_id` set) cannot carry `instance:*` scopes — the combination is irreconcilable (a bound credential cannot claim instance-wide authority) and is rejected with 422.
+
+### Effective Capability — `can(principal, capability)`
+
+```
+allow = role_grants(principal.instance_role, capability)
+      ∧ (principal.scopes.is_none() ∨ required_scope(capability) ∈ principal.scopes)
+      ∧ (principal.app_binding.is_none() ∨ capability.app_id() == principal.app_binding)
+```
+
+`role_grants` collapses the three tables (instance role + implicit app grants + explicit `app_members`) into a single yes/no. Each handler calls `state.authz.require(&principal, Capability::AppWrite(script.app_id))` after loading the resource (so the capability binds to the resource's actual `app_id`, not a path param the caller controls).
+
+### Deactivation Symmetry
+
+Phase 3a's `set_active(false)` wipes that user's `admin_sessions`. Phase 3.5 extends it to also set `expires_at = NOW()` on every row in `api_keys WHERE user_id = $1` — both credential surfaces become inert at the same moment, no enumeration window.
+
+### CLI Auth Posture (forward note)
+
+The eventual `picloud` CLI authenticates by **paste-the-token**, not OAuth: the user runs `picloud login`, the dashboard mints a fresh key (or the user mints one via `POST /api/v1/admin/api-keys`), and the CLI prompts for the raw token. The CLI binary itself is deferred; the dashboard surface and the bearer credential type land here so the CLI is a thin wrapper when it arrives.
+
+### Schema (Migration 0006)
+
+```sql
+ALTER TABLE admin_users
+  ADD COLUMN instance_role TEXT NOT NULL DEFAULT 'owner'
+    CHECK (instance_role IN ('owner','admin','member')),

+  scopes        TEXT[] NOT NULL,                          -- intersected with role at check time

+);
+CREATE INDEX api_keys_prefix_idx  ON api_keys (prefix);
+CREATE INDEX api_keys_user_id_idx ON api_keys (user_id);
+
+-- Reserved (not built this phase):
+--   invites (token, email, instance_role, app_id, app_role, invited_by, expires_at, consumed_at)
+--   service_accounts (id, name, owning_user_id, …)
+```
+
+### New Endpoints (additive — no API major bump)
+
+```
+POST   /api/v1/admin/api-keys        — { name, scopes[], app_id?, expires_at? }
+                                       → 201 { …, raw_token }   (raw returned exactly once)
+GET    /api/v1/admin/api-keys        — list caller's own keys (no raw)
+DELETE /api/v1/admin/api-keys/{id}   — caller's own only
+```
+
+Every existing `/api/v1/admin/*` endpoint is re-gated from "any authed admin" to a specific `Capability`. Request/response shapes are unchanged; what changes is the set of callers each endpoint accepts (a `member` now gets 403 on app surfaces they're not part of, where before they would have been 401-or-200 depending only on session validity).
+
+### Out of Scope (Phase 3.5)
+
+Schema room only, not built:
+
+- **Invites** — email-based join flow; `invites` table reserved in the migration comment block.
+- **MFA / TOTP** — `mfa_secret` column reserved on `admin_users`.
+- **Service accounts** — reserved as a future table; for now, every API key belongs to a human `admin_users` row.
+
+Defer to follow-up sessions: dashboard surfaces for invites / member management / key minting (curl is the supported interface this phase), OIDC / SAML / SCIM, the `picloud` CLI binary itself, email/SMTP delivery of invites, audit log shipping.

+Three foundation pieces that must land before the v1.1 service expansion, because retrofitting them later is expensive.
 
 **3a. Admin auth** — ✓ shipped. See section 11.4. Per-user `admin_users` (not a shared secret), Argon2id passwords, env-var bootstrap of the first admin, session-token doubling as bearer token for API. No roles in this cut; schema is forward-compatible with later RBAC.
 
-**3b. Multi-app scoping** — see section 11.5. Introduce `apps`, `app_domains`, and `app_id` columns on `scripts` and `routes`. Migration assigns existing data to a `default` app (or seeds a `Hello World` app on fresh installs). Orchestrator dispatch becomes two-phase (Host → app → route). Reserved internal domain (`__internal__`) keeps `/api/v1/execute/{id}/*` working for app scripts without requiring a public hostname. Dashboard becomes app-hierarchical (`/admin/apps/{slug}/...`); API keeps its existing flat shape with new app-management endpoints under `/api/v1/admin/apps/*`.
+**3b. Multi-app scoping** — ✓ shipped. See section 11.5. `apps`, `app_domains`, `app_slug_history` tables; `app_id` columns on `scripts`, `routes`, `execution_logs`. Migration assigns existing data to a `default` app and always claims `localhost`; a Rust-side bootstrap inserts a `Hello World` script + `/hello` route when the default app is empty. Orchestrator dispatch is two-phase (Host → app → route trie). `/api/v1/execute/{id}/*` continues to work without a public domain claim. Dashboard is app-hierarchical (`/admin/apps`, `/admin/apps/{slug}/...`); API stays flat with new endpoints under `/api/v1/admin/apps/*` and a `?app=` filter on script listing. Per-app admin roles deferred.
 
-**Why both before v1.1**: every v1.1 service (KV, docs, users, etc.) needs an `app_id` scoping key in its schema. Adding it now, with one small migration on existing tables, is cheap. Adding it after those services ship is several migrations on populated data.
+**3c. Users, roles, and bearer-token auth** — pending. See section 11.6. Adds `instance_role` to `admin_users` (`owner`/`admin`/`member`), `app_members` for per-app `app_admin`/`editor`/`viewer` grants, and `api_keys` for `Authorization: Bearer pic_…` credentials. Unifies cookie-session and API-key paths behind a single `can(principal, capability)` gate; list endpoints filter by membership at SQL for `member` users. Dashboard surfaces, invites, MFA, service accounts, and the `picloud` CLI binary are deferred — schema room only.
+
+**Why all three before v1.1**: every v1.1 service (KV, docs, users, etc.) needs both an `app_id` scoping key in its schema and a `Principal` to authorize against. Adding both now is one migration each on a small surface; adding them after the SDKs ship is many migrations on populated data plus a re-gate of every SDK call.
