Three client decisions for Denya OneCare / Pavilion Accra:
1. Technician roster converges to exactly 5 named techs
- Samuel Shang, Desmond Afful, Desmond Odekyi, Francis Norgbey, Nicholas Nartey
- New app/services/roster.py: converge_tech_roster() runs at startup and is
idempotent; off-roster techs are DEACTIVATED, never deleted, so ticket
history keeps a valid assignee reference
- seed.py SEED_USERS_DATA updated; placeholder emails until client confirms
2. Sub-contractors appear in the "Assign to" list alongside technicians
- New canonical role "Sub-contractor" (ASSIGNEE_POOL_ROLES = Tech + Sub-contractor)
- New GET /api/auth/assignees endpoint returns active pool members only
- Server-side _validate_assignee gate in ticket service rejects off-pool
or deactivated assignees (400/404)
- "Assign To" dropdown added to the new-ticket form; assigning at creation
auto-advances Logged -> Assigned
- base.html isTech() includes Sub-contractor (portal UX, tracked "under tech")
3. Penthouse units selectable when raising a ticket
- apartment_mapping.json: PH1E-/PH1W-/PH2E-/PH2W- -> clean codes
- seed_units self-heals legacy malformed codes on existing DBs and sets floors
- Penthouse units added to the built-in fallback seed
Tests: new tests/test_wahab_directives_20260928.py (8 tests); updated the
stale East unit count in test_categories_and_units.py (60 -> 62 with penthouses).
Full suite green.
