12 — Profiles — Subsystem Test Map

The profiles subsystem owns reusable per-room cleaning profiles (fan speed, water level, mop mode, etc.): the user library, the protected built-in profiles, applying a profile to a room, and saving/overwriting a profile from a room's current settings. Covered by 65 tests across 3 files.

What's tested

• Library CRUD — save / overwrite / rename / delete user room profiles, the protected built-in set, and the apply-to-room path.
• Save-from-room — building a profile from a room's current settings, including the overwrite-from-room variant.
• Pure normalization (unit) — room_profiles.py field coercion, protected names, and the profile-match resolution used to label a room's current config.
• Adapter-sourced catalog seam (unit, test_profile_catalog.py) — resolve_profile_catalog per-key merge of an adapter room_profiles block over the in-code defaults, catalog-driven resolution (resolve_room_profile_for_room honouring a catalog's floor-type water default, default_profile fallback, and a custom builtins entry), and None/empty block staying byte-identical to the in-code defaults (see 16 — profile manager §1.1).

---

How it's tested

ProfileManager over the manager fixture for the library/apply paths; the pure normalization + matching helpers are unit-tested in isolation.

Known gaps

manager.py (95%) is diffuse — single-line defensive returns and not-found guards scattered across the CRUD methods (the _safe_int empty/except path at 50/52/53, and continue skip-guards for non-dict entries at 623, 756, and the restore-profile not-dict guards at 1014/1018/1025/1028/1032/1033); no contiguous untested behavior block.

room_profiles.py (95%) is likewise defensive: the TypedDict ImportError fallback shim (10–11), empty-name continue guards (208), the vacuum_mop_standard alias fallback (342), the double-fallback when even default_profile is missing (263–264), and a capability-gating branch (484). All intentionally left uncovered.
