+  Add or extend support for a Samsung OCF appliance in localthings from a
+  /device/0 diagnostics dump. Use when a device-support issue lands, a device
+  raises the "incomplete capability coverage" repair, a diagnostics JSON needs
+  triaging, or you're mapping OCF resources to HA entities. Covers reading dumps,
+  OCF-standard vs vendor hrefs, the diagnostic/config/normal entity taxonomy,
+  ensuring every href is bound or ignored, and locking it in with a fixture +
+  golden + test.
+---
+
+# Adding device support
+
+localthings maps a Samsung appliance's OCF resources (`/device/0` dump) to Home
+Assistant entities. Each resource `href` is handled by a `Capability` that
+declares the entities it produces. This skill is the workflow for turning a new
+dump into coverage.
+
+## 1. Get the dump and see the gaps
+
+A user's diagnostics download (`config_entry-localthings-*.json`) has, under
+`data`:
+- `resources`: `{href: rep}` — the parsed `/device/0` snapshot. **This is the
+  source of truth**, not code comments.
+- `unbound_hrefs`: resources that bound to no capability. The
+  "incomplete capability coverage" repair fires whenever this is **non-empty or
+  the device type is unrecognized** (`coordinator._update_coverage_gap_issue`).
+
+Goal: make `unbound_hrefs` empty by **binding** the useful resources and
+**ignoring** the noise — and surface every genuinely useful sensor/select/switch
+along the way.
+
+## 2. Compute coverage without Home Assistant
+
+The `registry/` package is HA-free, so you can drive discovery directly (HA
+isn't importable standalone because `localthings/__init__.py` pulls it in — stub
+the package to skip that):
+
+```python
+import sys, types, json, importlib
+cc = types.ModuleType('custom_components'); cc.__path__=['custom_components']; sys.modules['custom_components']=cc
+lt = types.ModuleType('custom_components.localthings'); lt.__path__=['custom_components/localthings']; sys.modules['custom_components.localthings']=lt
+by_type   = importlib.import_module('custom_components.localthings.registry.by_type')
+discovery = importlib.import_module('custom_components.localthings.registry.discovery')
+adapter   = importlib.import_module('custom_components.localthings.registry.adapter')
+
+resources = json.load(open('dump.json'))['data']['resources']
+info = resources['/information/vs/0']
+reg = by_type.for_device_by_model(info['x.com.samsung.da.modelNum'], info['x.com.samsung.da.description'])
+# or: by_type.for_device(one_ui_version)  when /otninformation has swVersionInfo.oneUiVersion
+unbound = []
+bound = discovery.discover(resources, reg.capabilities, reg.pattern_capabilities, log=unbound.append)
+state = adapter.flatten(bound, resources)   # {entity_key: value}
+print('registry:', reg.name, 'unbound:', sorted(unbound))
+print('state_keys:', sorted(state))
+```
+
+`discover()` binds caps (applies `rt_filter`/`match_fn`); `flatten()` applies
+`exists_fn` and produces the final entity values. Use the same routine to
+regenerate a golden.
+
+## 3. OCF-standard vs vendor hrefs (`/x/0` vs `/x/vs/0`)
+
+Samsung appliances run RT-OCF and often expose the **same state twice**:
+- `/x/vs/0` — **vendor** resource, `x.com.samsung.da.*` fields.
+- `/x/0` — **standard OCF** resource type (`oic.r.*`) with OCF's fixed field
+  names. Confirmable against the OCF spec: `/power/0` `{value: bool}` is
+  `oic.r.switch.binary`; `/operational/state/0` is `oic.r.operational.state`.
+
+Newer firmware advertises both as Samsung migrates onto the OCF standard. **There
+is no single "always prefer vs / always prefer non-vs" rule** — decide per
+resource from the populated dump:
+- **Both populated, same state** (power, kids-lock, remote): prefer the
+  OCF-standard `/x/0`; fall back to `/x/vs/0` when `/x/0` is absent. Encode with
+  a `match_fn` presence check — see `common.POWER_GENERIC` / `POWER_VS_FALLBACK`.
+- **Only vendor populated** (`/energy/consumption/0` is often empty `{}`): use
+  `/x/vs/0`.
+- **Vendor is a superset** (`/operational/state/vs/0` adds fields the OCF one
+  lacks): build on the vendor resource, ignore the OCF subset.
+
+Course/cycle is **not** an OCF question — there's no standard course resource, so
+`/course/vs/0` (and the `/st/*course/vs/0` re-encoding) are both vendor.
+
+## 4. Entity taxonomy — the judgement call
+
+For each field worth exposing, decide the entity kind and category
+(`entity_category` on the descriptor):
+- **Normal / primary** (no `entity_category`): the things a user acts on or
+  watches — power switch, machine state, the cycle select, energy sensors.
+- **`config`**: user-tunable settings — sound mode, door LED, wash temperature,
+  buzzer. Shown under the device's Configuration section.
+- **`diagnostic`**: read-only status/troubleshooting — alarms, diagnosis, job
+  beginning status, last-operation source.
+
+Also set `poll_tier` (`hot`/`warm`/`cold`) on the capability for how often it's
+sub-polled between summary polls. Pick descriptor types from `entities.py`
+(`SensorDesc`, `SelectDesc`, `SwitchDesc`, `NumberDesc`, `BinarySensorDesc`,
+`TimeDesc`, `ButtonDesc`) — the class selects the HA platform.
+
+**Don't guess.** If a field's meaning or write contract is unclear from the dump
+(opaque encoded blobs, no supported-values list), leave it unbound so it surfaces
+as a gap for a human, or ignore it with a documented reason — never invent an
+entity on a hunch (`ignored.py`'s rule).
+
+## 5. Enum selects need translation support
+
+Any select whose options are raw device codes (course/cycle, and code-valued
+settings) must render through translations, not Python:
+- Set `translation_key='<family>_cycle'` (or similar) on the `SelectDesc`;
+  `options`/`options_field` supply the **raw** codes.
+- Add the labels to **both** `strings.json` and `translations/en.json` under
+  `entity.select.<translation_key>.state.<code>`, with the code **lowercased**
+  (e.g. `"16": "Cotton"`). Codes with no entry render as the raw code — that's
+  the cue to identify and name them.
+
+## 6. Coverage discipline: bound or ignored
+
+Every href in the dump must resolve, or the repair fires. If a resource isn't
+worth an entity, add it to `capabilities/ignored.py` (a no-entity `Capability`)
+with a one-line reason. Add there only when it's **irrelevant plumbing**
+(network/OTA/account housekeeping) or a **duplicate of state exposed via a
+friendlier href**.
+
+- **Global vs per-registry ignore:** `ignored.IGNORED` is folded into every
+  registry. A global ignore **collides** (via `_build`) with any real capability
+  that binds the same href in some family — e.g. `/course/vs/0` can't be globally
+  ignored because washers bind it. When only one family should ignore an href
+  that another binds, scope the ignore to that family's registry.
+
+## 7. Reuse before writing new code
+
+Check `common.py` (generic OCF: power, energy, alarms, water) and `laundry.py`
+(shared washer/dryer/dishwasher: buzzer, job status, `cycle_select` + course
+machinery) before adding a capability. Cross-family reuse is normal — the dryer
+registry uses `fridge.FIRMWARE_UPDATE`; all three laundry families share
+`laundry.cycle_select`. If two families hand-roll the same helper, hoist it to a
+shared module rather than copying.
+
+## 8. Lock it in
+
+1. Add a **scrubbed** fixture `tests/fixtures/<type>_device.json`
+   (`{"device0": [ {devcol rep}, {href, rep}, ... ]}`) — replace serials, MACs,
+   and other PII with placeholders.
+2. Generate `tests/fixtures/golden/<type>.json` (`{"state_keys": [...]}`) with
+   the harness in §2.
+3. Add the type to `test_golden_regression.py` and write a
+   `test_<type>_capabilities.py` asserting **zero unbound hrefs** and that the
+   expected entities exist (and any misleading ones are gated).
+4. Run `pytest tests/ -q` — and re-run the golden tests for **other** device
+   types after any change to `common.py`/`laundry.py`, since they share those.
+
+## Key files
+- `registry/discovery.py` — `discover()`, unbound reporting, pattern caps.
+- `registry/capability.py`, `registry/entities.py` — the `Capability` and
+  descriptor shapes (`rt_filter`, `match_fn`, `exists_fn`, `rep_fn`, `write_fn`).
+- `registry/capabilities/{common,laundry,fridge,...}.py` — capability defs.
+- `registry/capabilities/ignored.py` — the ignore list + its philosophy.
+- `registry/by_type/*.py` — per-device-type registries (what to include).
+- `registry/registry.py` — the global unknown-device fallback + collision check.
+- `tests/test_golden_regression.py`, `tests/fixtures/` — regression harness.

+"""Climate platform for Local Things.
+
+The first composite entity in this integration: a single HA climate card that
+unifies several OCF resources of a Samsung air conditioner. Unlike every other
+platform here (one descriptor -> one resource field), a climate entity reads
+power, HVAC mode, current/target temperature, fan (wind) strength, swing (wind
+direction) and the convenient-mode preset from *different* resources.
+
+It binds one primary `BoundEntity` (the `/mode/vs/0` capability) so the registry
+still tracks it, and reads the sibling resources straight from the coordinator
+snapshot via `coordinator.resource(href)` -- the same cross-resource read that
+`number.py` (live range/unit) and `select.py` (options callable) already do.
+
+Writes go through `coordinator.async_send_command(bound, (kind, value))`: the
+CLIMATE capability's `write_fn` maps each `(kind, value)` payload to the right
+`(path_segs, body)`, and `async_send_command` POSTs to those path_segs (the
+bound href is only used for logging), so one descriptor drives writes to power,
