 The two roles are distinguished by **display only**. `User.INSPECTOR_ROLES = ('inspector', 'external_inspector')` and the `User.is_inspector` property are the single definition — **every** capability/scoping check tests `is_inspector`, never `role == 'inspector'` (rule 87). `User.is_external_inspector` and `User.role_label` (backed by the `ROLE_LABELS` map) drive the "External" badges: users list, dashboard **Inspector Activity**, **Inspector Performance** report (HTML + the Excel export, where the name cell is suffixed `(External)` rather than gaining a column so the index-based cell styling stays correct), and every assignee dropdown (`(External)` suffix — issues create/update, issue-list quick-assign, inspection flag-issue).
 
+**Invited, not provisioned (Aug 2026).** An external inspector works outside the business, so an admin never sets their password. Creating one at `/auth/users/new` follows the customer invitation flow instead: the account is stored with `password_set=False` and a random placeholder hash, a 72-hour `set_password_token` is minted, and `customers._send_invite_email()` (reused unchanged — its copy already fits any invited account) sends a link to **`/customers/set-password/<token>`**, where they choose their own **username and password**. `login()` refuses `password_set=False` until they finish. `POST /auth/users/<id>/resend-invite` (admin-only) mints a fresh token and re-sends — without it a bounced or expired invitation would leave the account permanently unusable. The users list shows an **"Invite pending"** badge and the resend button while `password_set` is false. Every other role is unaffected: they are still created with an admin-set password, and `create_user()` now **rejects a blank password** for them rather than storing the hash of an empty string.
+
 Assignable (rule 80 set becomes `director`/`inspector`/`external_inspector`/`auditor`, plus `project_manager` on the inspection flag-issue dropdown), included in Inspector Performance and Inspector Activity, and has **mobile-API access** — `external_inspector` is in the `_ALLOWED_ROLES` of every `app/api/*` module and falls into the inspector branch of every scoping check there. It gets its **own Notification Matrix column** (`external_inspector`), whose defaults mirror the Inspector column (see §11).
 
 **`auditor` (Phase 40):** A staff role with the **same access as `project_manager`** (it is included in `@project_manager_required` and everywhere `project_manager` is checked) **plus full issue-management powers** — create, assign, quick-assign, handler/vendor triage, request-verification, and verify/bulk-verify/verification-queue (via the new `@issue_manager_required` decorator). **Auditor does NOT get issue deletion** (that stays admin/director via `@supervisor_required`), nor any other admin/director-only area PM lacks (users, audit trail, notification matrix, customers, templates). Auditors are **assignable** as an issue/inspection assignee; **admin was removed** from the assignable set at the same time (assignee dropdowns are now `director`/`inspector`/`auditor`, plus `project_manager` on the inspection flag-issue dropdown). The issue-update route defensively keeps any pre-existing out-of-set assignee (e.g. a legacy admin assignment) in the dropdown so saving never silently unassigns. Auditor **has mobile-API access** — it is included in the `_ALLOWED_ROLES` set of every `app/api/*` module (comments, inspections, issues, photos, scheduled, stats, templates), so the iPad app accepts auditor logins. In every API endpoint that scopes by role, auditor falls into the non-inspector/non-customer (privileged) branch — org-wide data, same as admin/director/PM.
