EPIC18/§19. analyst sees everything (deals, insights, exports, site-finder,
analytics, concept) EXCEPT admin/data-management. Enforcement is backend-hard
(the existing rbac_guard already 403s any non-admin role on /api/v1/admin/*, so
adding the role auto-blocks it) + frontend (deny_paths via /me) + audit.
§19 audit: new best-effort HTTP middleware logs the sensitive actions
(analyze / forecast / forecast-export) to a new audit_log table after the
response. Audit failures never break or delay-fail the request (2-layer
try/except + finally close). Registered INNER to rbac_guard so only authorized
requests are audited (a 403 short-circuits before audit). classify_path matches
export before forecast (anchored).
- auth/roles.yaml: analyst role (paths /**, deny admin-mgmt) + analysttest QA user
- core/auth.py (+ tradein mirror): Role Literal += analyst
- core/audit_middleware.py (new) + main.py registration
- data/sql/144_audit_log.sql (idempotent; auto-applies)
- tests: analyst rbac (403 admin / 200 parcels) + 11 audit cases
No data-level ACL (analyst sees data per policy) -> no #948 dependency. No new
deps. parcels.py untouched. Real analyst logins still need adding to
caddy/users.caddy.snippet (devops).
