+detection path (`for_device_by_oic_type`, stage 1 above) — it sits outside
+the `/device/0` dump, read separately by `registry/identity.read_identity`,
+which fetches three endpoints in one shot:
+- **`/oic/d`** — the device type itself: `n` (device name) and `rt`, a list
+  carrying the generic `oic.wk.d` base type every OCF device has alongside a
+  concrete one (`oic.d.airconditioner`) or a SmartThings vendor extension
+  (`x.com.st.d.stickcleaner`, for categories with no `oic.d.*` equivalent —
+  same prefix convention as `x.com.samsung.da.*` resource fields elsewhere).
+- **`/oic/p`** — platform identity: `mnmn`/`mnmo` (manufacturer/model).
+- **`/oic/res`** — resource discovery, used for subdevice enumeration (§11),
+  not device typing.
+
+None of the three appear in `resources`; find them in diagnostics' `identity`
+block (`identity.device_types`, `identity.manufacturer`, `identity.model`),
+or read live with `read_identity(sess, serial)` if you're driving a device
+directly.
+
+**Whenever you triage a dump, check `identity.device_types` before touching
+`_BOARD_TOKEN_TO_KEY` at all** — the whole point of this stage running first
+is that a real `/oic/d` type makes board-token routing unnecessary. Two
+outcomes:
+- The type is already a key in `_OIC_TYPE_TO_KEY` (`registry/by_type/__init__.py`)
+  → detection already works; an unbound-hrefs gap on this device is a
+  capability-coverage problem (§§4–9), not a routing one.
+- The type is **not yet in the table** → add a row. This is now the
+  integration's primary detection method, and it only stays that way if new
+  types get folded in as real dumps surface them — same discipline that
+  keeps `_BOARD_TOKEN_TO_KEY` current:
+
+```python
+'oic.d.dishwasher': 'dishwasher',
+'x.com.st.d.steamcloset': 'air_dresser',
+```
+
+- A string not yet seen in a dump is still fine to add on the strength of the
+  OCF Smart Home Device Specification's Table 9-1 alone, as long as it has the
+  exact same `oic.d.<category>` shape as an already-confirmed entry — that
+  shape is low-risk ahead of a dump because, unlike a board-token entry,
+  there's no tokenizing or delimiter-spelling judgment call involved.
+- **Only add a row once there's a real registry key on the right** (a key in
+  `_REGISTRY_BY_KEY`). A type naming a product this integration has no
+  registry for stays unmapped rather than getting coerced onto the
+  nearest-sounding one — `oic.d.robotcleaner` names an actual robot vacuum,
+  a different product from the clean/auto-empty *station* `vacuum_station`
+  covers (no vacuum-body capabilities at all; see that registry's own module
+  docstring), so it's deliberately absent even though the string is known.
+- Falls through to `for_device_by_model`/`for_device_by_resources` when
+  `device_types` is empty or maps to nothing — most hardware still doesn't
+  populate `/oic/d` usefully, so those two stages stay load-bearing for
+  everything this one doesn't catch.
+- On a multi-subdevice appliance, `device_types` only ever comes from the
+  *master's* `/oic/d` (`discover_partitioned`'s `oic_device_types` param) —

+  this routinely (issue #196's sound-mode/volume controls, issue #181's
+  power-level ask), so shipping a flagged guess and asking for confirmation
+  is the established pattern, not a new one.
+
+Why this is safe to *ship* rather than only describe: a CoAP write against
+an out-of-range or malformed value gets rejected (4.xx), not acted on — the
+worst case for a wrong *value* is a no-op, not a damaged or misbehaving
+appliance. That margin only covers the value, though, not the semantics:
+bind a guessed write to the device's own reported range/supported-list
+rather than inventing bounds, and don't guess a unit the dump gives no way
+to cross-check (temperature scale, minutes vs. seconds) — being
+syntactically valid but semantically backwards is exactly the case a
+rejection won't catch.
+
+The same unit caveat applies on the **read** side, but with a sharper
+failure mode: a guessed `unit`, `device_class`, or `state_class` on a
+`SensorDesc` silently mislabels the entity in HA forever (every reading,
+every graph, every long-term statistic), with no 4.xx to catch it. The
+write-rejection safety net above doesn't cover reads — the device happily
+returns whatever it returns. So the read-side equivalent of "bind a write
+to the device's own reported range/supported-list" is: leave `unit`/
+`device_class`/`state_class` unset when the dump gives no field that
+nominates one (no `supportedGrades`, no second dump to compare against,
+no family member whose same field is already mapped). Match an
+already-bound descriptor on a sibling family when the underlying field
+and value shape are identical; otherwise expose the reading without an
+HA-level interpretation and let a future reporter or dump confirm it.
+See `air_monitor.AIR_QUALITY`'s docstring for the worked example
+(three dust keys, no `device_class`, no `unit`).
+
+Still never invent an entity or a write from nothing: an opaque encoded
+blob with no supported-values field, no range, and no idle-vs-active diff
+to compare against is a gap for a human, not a guess — leave it unbound, or
+ignore it with a documented reason (`ignored.py`'s rule).
+
+Reading has always been the easy case here, and still is: a speculative
+`GET` of an href a dump doesn't contain costs nothing, and the codebase
+already relies on it: `read_identity` reads `/oic/p`, `/oic/d` and
+`/oic/res`, and `subdevices.enumerate_subdevices` probes `/device/<n>`,
+`/<uuid>/device/0` and `/multidevice/vs/0` on every device — and, when a
+prefixed candidate's own `/<uuid>/device/0` doesn't answer (issue #205: not
+guaranteed even on the board this pattern was built against), every href
+the master itself answered this cycle, individually under that UUID's
+prefix (see §11). A RETRIEVE is non-mutating and a 4.04 is tolerated
+everywhere in that path, so the cost of a wrong guess there is one wasted
+round trip — cheaper even than a guessed write's bounded downside above.

+## 11. Triage: "one of my subdevices is missing"
+
+For an appliance that exposes several logical indoor subdevices over one IP —
+a 2-in-1 air conditioner, plausibly a multi-drum washer (#19). Work down
+the dump in this order; each step rules out a different cause.
+
+1. **`subdevice_probes`** — did we even look? Every seed attempted appears
+   here with what it returned. An absent seed means enumeration never tried
+   that path; a `false` means it tried and got nothing. On a UUID-prefixed
+   board whose `/<uuid>/device/0` reads `false` (issue #205 — this isn't
+   rare, not even on the board the pattern was built against), the report
+   also carries one probe per href the master itself answered that cycle,
+   individually under that prefix (`subdevices.enumerate_subdevices`'s flat
+   fallback) — a `true` there is real, confirmed-live evidence for that one
+   href, not a guess.
+2. **`subdevices`**/**`flat_hrefs`** — for a *materialized* subdevice found
+   this way, `flat_hrefs` lists exactly which hrefs it's actually being
+   polled on (individually, no Collection endpoint to batch through) —
+   compare against the master's own hrefs to see what's still unconfirmed
+   for that sibling.
+3. **`subdevices_skipped`** — did we find it and reject it? A candidate lands
+   here when its seed(s) answered but it produced no *primary*
+   (non-diagnostic), non-meter entity with a populated value. Its
+   `resources` block holds the exact reps the gate judged, so you can check
+   the call yourself. If every power/mode/temperature rep is `{}`, the
+   subdevice is an unused slot and the skip is correct — a populated
+   `/energy/consumption/vs/<n>` alongside them doesn't change that (issue
+   #214: an appliance's lifetime kWh counter shows up under an unused
+   slot's index too, and materializing on it produced a phantom duplicate
+   air conditioner, so cumulative meters are excluded from the gate). If
+   the *operational* reps are populated, the gate is wrong — that's a bug
+   worth a fixture. A flat-fallback candidate whose
+   only confirmed href is `/information/vs/0` (never bound to any entity —
+   only ever read for device-type resolution) will *always* land here until
+   more of its hrefs are confirmed live; that's the gate working as
+   intended, not a bug to chase.
+4. **`multidevice.numofsubdevice`** — the board's own count, where it
+   reports one. `coordinator._run_discovery` compares it against
+   `len(materialized) + 1` (materialized subdevices plus the master) and
+   only warns on disagreement — `subdevices_skipped` entries don't count
+   toward either side, since they never materialized. A strong hint, not
+   proof; only one board family is known to expose it.
+5. **Which pattern is this board?** `identity.resources['/oic/res']` listing
+   `/device/1`, `/device/2` means indexed siblings. `resources['/subdevices/
+   vs/0']` carrying a `subdeviceIdList` means a UUID-prefixed tree, and that
+   same UUID usually shows up as an href prefix in `/oic/res` too — enumerate
+   whether or not `/<uuid>/device/0` itself answers, per §5's fallback.
+   Neither present, on a device the owner insists has two subdevices, is the
+   interesting case — that's a third mechanism and needs a new dump, not a
+   code guess.
+
+Two things that are *not* the fix: adding a capability for an indexed href
+(see §8), and loosening the liveness gate to "any populated entity" — a
+rejected slot routinely reports a non-`None` *diagnostic* value off an empty
+resource (and, on some boards, a populated appliance-level meter), which is
+exactly what the primary-entity and meter filters exist to ignore.
+
+### The mirror image: "I have one subdevice too many"
+
+Same dump, read the other way (issue #214). A duplicate device in HA is
+either a candidate that shouldn't have materialized — check `subdevices`
+for one whose `resources` are all `{}` except a meter/`/information`, which
+is the unused-slot shape from step 3 — or a **leftover registry entry** from
+a release that did materialize it. Those two look identical in the HA UI and
+are told apart by the dump: a leftover shows `subdevices: []` (or no entry
+for that key) while the device is still listed in HA.
+
+Nothing prunes a leftover automatically — subdevice enumeration is one-shot
+and a real sibling can miss a poll, so auto-removal would throw away a live
+subdevice's name/area/automations on a transient miss. The integration
+implements `async_remove_config_entry_device`
+(`custom_components/localthings/__init__.py`) instead, which is what puts a
+working "Delete device" button on anything this entry no longer provides;
+devices it *does* provide refuse removal, since HA would just recreate them.
+Tell the reporter to delete the stale device, don't add a pruning pass.

The flow sends a DTLS `ClientHello` to every port in the `49152-49160` range at once and keeps the one that answers -- a real DTLS server identifies itself in about one round trip, and the probe stops there, so nothing is left behind on the appliance. Only that port is then given a real certificate handshake: it fetches the current UUID from Samsung's cloud gateway, mints a leaf cert signed by your CA, and reads the device's identity and `/device/0`. On success it creates the config entry, already knowing the appliance's serial, model, and type.

+Each device has its own **Configure** option in Settings > Devices & Services, under **Device settings**:
+
+- **Allow writes even when remote control is reported off** — by default, LocalThings blocks every write with a clear error whenever a device reports remote control off, rather than letting the device silently reject it. Some devices accept certain writes anyway (e.g. default detergent/softener dosing on a washer) even while reporting remote control off. Only enable this if you've confirmed writes actually work on your device with remote control off — otherwise you trade a clear error for a silent failure.
+- **Estimated finish -- minimum change (minutes)** — a washer/dryer/dishwasher's `finish_time` sensor is recomputed from the device's own remaining-time estimate on every poll, which commonly drifts or gets revised by a minute or two between updates. This setting holds `finish_time` at its last reported value until a new estimate differs by at least this many minutes, cutting down on Home Assistant history/logbook noise from a value that hasn't meaningfully changed. Defaults to `3`; set it to `0` to report every computed change.

 If reconnects become persistent (more than a handful per minute), something's actually wrong. Check the appliance's Wi-Fi link first, then look for a competing DTLS client on the LAN — only one active session per appliance is allowed at a time.
 
+### Multi-subdevice ("2-in-1") air conditioner systems
+
+Some Samsung installs run more than one indoor subdevice off a single outdoor unit, all reachable over the *one* IP/DTLS session your config entry connects to (a floor-standing + wall-mounted 2-in-1 is a common shape). The integration discovers any sibling subdevices automatically, once, right after the first successful poll — there's nothing to configure. Each discovered subdevice gets its own HA device (linked to the main one via "via device") and its own `climate` card, so it lands in its own room in the dashboard instead of being invisible or mixed into the master's state.
+
+Two on-the-wire shapes are supported, both keyed off what the appliance itself reports:
+
+- **Indexed siblings** — the device answers a `/device/1`, `/device/2`, ... collection alongside its own `/device/0`, mirroring every resource at that index.
+- **UUID-prefixed tree** — the device reports a sibling's id in `x.com.samsung.da.subdeviceIdList`, and that id doubles as a literal href prefix for the sibling's own resource tree.
+
+A candidate that answers but never produces any real, user-facing state (an unused slot some installs report alongside a genuine second subdevice) is silently skipped rather than turned into a phantom entity — check diagnostics' `subdevices`/`subdevices_skipped` blocks if a subdevice you expect to see isn't showing up, and file an issue with that diagnostics download attached.

+"""Capabilities for the Samsung Air Monitor Plus family (ASM-KR-TP1-22-*
+board, issue #210) -- a small battery-powered standalone air-quality sensor
+puck, not a controllable appliance. No `/power/*` resource at all (battery
+only); this registry deliberately doesn't include common.POWER.
+
+`/sensors/vs/0` is the same {type, value: [...]} items-list shape
+air_purifier.AIR_QUALITY and range_hood.AIR_QUALITY already read via
+common.sensor_item_value -- reused here rather than re-decoded, including
+the same dust/fine_dust/super_fine_dust/odor/clean_level keys so this
+device shares those capabilities' catalog entries. This board additionally
+reports a CO2 reading the other two families don't.
+
+A second `value` list element on the particulate-matter types (e.g. Dust's
+`['31', '2']`) reads like a coarse quality-grade code, but nothing on this
+board (no `supportedGrades`/similar field, no repeated dump to compare
+against) confirms what its scale means -- left unbound rather than guessed,
+per the adding-device-support skill's "still never invent... from nothing"
+rule. Same reasoning `air_purifier.AIR_QUALITY` already applies to this
+shape; index 0 is the only slot any family has ever read.
+
+Dust/FineDust/SuperFineDust aren't assigned an HA `device_class`
+(pm10/pm25/pm1) or `unit` despite the values reading like plausible
+ug/m3 particulate readings in a physically consistent order (coarser
+>= finer): Samsung's own two-tier Korean convention (i.e. "fine dust"/
+"ultra-fine dust") maps only to a PM10/PM2.5 pair, and this board's
+three-tier naming doesn't confirm where the extra tier or a PM1 reading
+actually fits. The adding-device-support skill's read-side rule says
+leave unit/device_class unset when the dump gives no field that
+nominates one -- a wrong guess would silently mislabel every reading
+forever, and the write-side rejection safety net doesn't cover reads.
+Exposed as plain `measurement` sensors named after the device's own
+field instead (matching air_purifier.AIR_QUALITY's existing precedent).

+
+An EHS unit runs two independently-controlled loops off one outdoor unit:
+space heating/cooling ("zone1", through /mode/vs/0, /power/vs/0,
+/temperatures/indoor/vs/0) and domestic hot water ("dhw", through

+vocabulary with the room-AC family in airconditioner.py beyond the DA_AC_
+board prefix -- EHS reports its own /mode/*/vs/0 and /temperatures/*/vs/0
+shapes, not airconditioner.py's HREF_MODE/HREF_TEMP* OCF-pattern hrefs.
+
+zone1 has no HA platform with matching semantics (it's a leaving-water-
+temperature setpoint, not a thermostat with HVAC modes airconditioner.py's
+climate.py would fit), so it stays switch/select/number/sensor -- same shape
+as dehumidifier.py's power/mode/humidity split. dhw is a real HA
+water_heater.py -- see DHW below and water_heater.py's module docstring --
+following the same primary-resource-plus-sibling-reads pattern as

+"""Subdevice ("composite device") support for one physical connection exposing
+more than one logical indoor subdevice -- issue #177.
+
+Two reporters, two different board families, two genuinely different
+mechanisms for exposing a second indoor subdevice over one IP / one DTLS
+session (see DESIGN-177.md section 1 for the full evidence trail; the two
+diagnostics dumps this was built against come from the Pattern A and
+Pattern B reporters, respectively -- they each filed one of the two
+reports this module unifies):
+
+Pattern A -- indexed siblings (`ARTIK051_DONGLE_FAC_18K`, that reporter's
+board). `/oic/res` lists three complete parallel resource sets whose
+trailing path segment is the index (`/mode/vs/0`, `/mode/vs/1`,
+`/mode/vs/2`, ... on both OCF-standard and vendor hrefs), and `/device/0`'s
+batch carries only the index-0 hrefs -- the sibling subdevices are
+reachable only via their own `/device/<n>` collection.
+
+Pattern B -- UUID-prefixed tree (`TP2X_FAC_BORA_21K`, that reporter's board).
+`/oic/res` hides the whole appliance tree; `/device/0`'s batch instead
+carries `x.com.samsung.da.subdeviceIdList` on `/subdevices/vs/0`, and that
+same UUID appears as a literal href prefix in `/oic/res`
+(`/<uuid>/file/list/vs/0`, ...). What's actually been confirmed live on
+that reporter's unit is narrower than early issue #177 writeups suggested: a
+single individual `GET /<uuid>/information/vs/0` was read by hand through
+the debug panel and came back carrying a different model/serial than the
+master (`TP2X_FAC_BORA_RAC_21K`, the wall-mounted subdevice, vs. the
+master's `TP2X_FAC_BORA_21K`, the floor subdevice) -- real evidence a
+second subdevice exists at that prefix, but not evidence that `GET
+/<uuid>/device/0` (the Collection batch PR #199 built this pattern's seed
+around) itself returns anything. Issue #205, the same unit on a later
+version, is that assumption failing: `/<uuid>/device/0` comes back empty.
+So `enumerate_subdevices` tries it first (a future board might genuinely
+expose it) and falls back, when it's empty, to probing every href the
+master itself answered this cycle individually under the UUID prefix --
+the only thing ever actually confirmed to work for this pattern -- on the
+assumption that a composite device's siblings share the master's resource
+surface. See `Subdevice.flat_hrefs`.
+
+Pattern C -- UUID prefix advertised only via `/oic/res`
+(`AWM-WW-AID-26-ONEBODY` washer+dryer combo, issue #241). The board answers
+`numofsubdevice='2'` on `/multidevice/vs/0` but has no `/subdevices/vs/0`
+(no `subdeviceIdList`) and 4.04s `/device/1`/`/device/2`; the washer
+subdevice's UUID appears nowhere except as the path prefix of the
+`x.com.samsung.da.multidevice` link in `/oic/res`, and
+`GET /<uuid>/device/0` answers the washer's own full Collection batch
+(model `..._WF80H` vs. the master's `..._DV80H27H`) -- Pattern B's
+transform with the UUID sourced from the link prefix instead of
+`subdeviceIdList`.
+
+All of these are "the same thing wearing different clothes": a logical subdevice is a
+seed collection path to poll, plus an href transform between the canonical
+href the registry knows (`/mode/vs/0`) and the actual on-the-wire href. The
+detection signals don't overlap on either captured board (the Pattern A
+reporter's has no `/subdevices/vs/0` at all; the Pattern B reporter's has
+no `/device/1`), so no disambiguation logic is needed --
+`enumerate_subdevices` checks both and materializes any candidate whose
+seed answers with a non-empty batch.
+
+A non-empty seed batch is necessary but not sufficient for the *candidate*
+to actually be a live second subdevice, though: the Pattern A reporter's
+own board also has a `/device/2` -- a third, unused SmartThings slot --
+that answers with the exact same 14-href shape as the real `/device/1`
+sibling, populated with three constant/echoed/shape-only reps (a region
+code identical to every other subdevice's, an /information rep echoing the
+*same* model string as subdevice 1, and a /temperatures items[] entry with
+an id/description but no current/desired/minimum/maximum reading) and
+nothing resembling live climate state. Gating on *resource* shape/hrefs
+turned out to be the wrong layer -- it would need per-family domain
+knowledge (which hrefs mean "in use" for a washer's second drum, a
+fridge's second compartment, ...) baked into a registry field before any
+of those families could use this module at all. `discover_partitioned`
+instead gates at the *entity* layer, after discovery+flattening: a
+candidate is only kept if it produced at least one *primary* (no
+`entity_category`), non-meter bound entity whose flattened value isn't
+`None` -- e.g. the Pattern A reporter's /device/2 does flatten to an
+`alarm_code` value, but that entity is diagnostic-category and derived from
+an empty /alarms/vs/2, so it doesn't count. This reuses the same
+primary/config/diagnostic taxonomy every registry already declares (see the
+adding-device-support skill's entity-taxonomy section) instead of adding a
+second, parallel domain-knowledge mechanism.
+
+The meter carve-out is issue #214, and it's the same "an unused slot still
+answers *something*" problem one layer further in: that reporter's
+single-split ARTIK051_KRAC_18K has a /device/1 whose operational reps are
+all empty {} -- the /device/2 shape above -- but which also reports a
+populated /energy/consumption/vs/1, a whole-appliance lifetime kWh counter
+that materialized the slot as a phantom second air conditioner. See
+`_has_live_primary_entity`.

+"""Water heater platform for Local Things.
+
+Second composite entity in this integration (see climate.py's module
+docstring for the general pattern this follows): a single HA water_heater
+card for a Samsung EHS heat pump's domestic hot water (DHW) loop. It binds
+the primary `WaterHeaterDesc` (the `/mode/dhw/vs/0` capability, DHW.entities
+in registry/capabilities/ehs.py) so the registry still tracks it, and reads
+the sibling `/power/dhw/vs/0` and `/temperatures/dhw/vs/0` resources straight
+from the coordinator snapshot -- the same cross-resource read climate.py uses
+for the AC's power/temperature/wind siblings.
+
+Writes go through `coordinator.async_send_command(bound, (kind, value))`:
+DHW's `write_fn` (ehs._dhw_write) maps each `(kind, value)` payload to the
+right `(path_segs, body)`, and `async_send_command` POSTs to those path_segs
+and applies the optimistic value/settle guard to that same href -- not the
+bound `/mode/dhw/vs/0` href -- so one descriptor drives writes to, and gets
+fresh state back for, power, mode and temperature alike.
+
+Operation-mode vocabulary: the DHW loop's four device modes (Eco/Std/Force/
+Power) map onto HA's own standard water_heater states -- the same mapping
+Home Assistant's core `smartthings` integration uses for this exact Samsung
+capability over the cloud API (`samsungce.ehsThermostat` /
+`airConditionerMode`: eco/std/force/power -> STATE_ECO/STATE_HEAT_PUMP/
+STATE_HIGH_DEMAND/STATE_PERFORMANCE), just title-cased to match this OCF
+resource's own code spelling. Reusing HA's standard states means no *state*
+translation catalog entry is needed for them (see the entity_component
+fallback in homeassistant.components.water_heater.strings.json).
+
+Naming is a separate question from that, and the answer here differs from
+climate.py's: the AC *is* the device, so its climate card takes the bare
+device name (`_attr_name = None`). An EHS unit has two loops, and the DHW
+one is not "the device" -- its siblings are named "Zone Mode"/"Zone Target
+Temperature", so a card labelled just "EHS" would misrepresent which loop
+it drives. This entity is named through the catalog like every other
+descriptor here, via the DHW descriptor's `translation_key='dhw'`
+(entity.water_heater.dhw.name -> "Hot water").

The reporter's own master resources were not quoted in the issue, so the master half of this fixture is that unit's stand-in. The /device/1 seed is the reporter's real slot, read off the `subdevices` block of their v0.17.0 diagnostics download (issue #214 comment 5131166356) and re-indexed from the canonical hrefs diagnostics reports back onto the real /x/1 hrefs the board answers on -- every rep is their value verbatim, including the empty {} on every operational resource and the populated /energy/consumption/vs/1, which is the whole point of this fixture. Two deliberate deviations: /information/vs/1 carries *this* fixture's master /information/vs/0 rep rather than the reporter's modelNum, because what their dump shows is the slot echoing its own master's model verbatim (ARTIK051_KRAC_18K|10193441|60010123001111110100000000000000, identical to their master's) and pasting that string against a different unit's master would misrepresent the slot as reporting a *different* model, which is what a real sibling does (see airconditioner_artik051_dongle_fac_18k_device.json's FAC_RAC subdevice); and /file/information/vs/1's +03:00 offset is the reporter's, so it doesn't match this master's +01:00 -- an artifact of the two halves coming from different units, not something the board did. oic_res is empty because the reporter's wasn't quoted either: enumeration therefore reaches /device/1 through the speculative _SPECULATIVE_DEVICE_INDICES probe, which is the path any board that doesn't advertise a sibling in /oic/res gets. Expected outcome: the candidate is found, then correctly held back by discover_partitioned's liveness gate -- a lifetime kWh counter is not evidence of a second indoor unit (issue #214)."

Filed specifically because, contrary to the assumption that fixture's seed batch was built on, this unit's /6c2dff6d-ee5c-dad1-6a5e-000000000001/device/0 does NOT answer (subdevice_probes in the report shows it False), so the Collection-batch fallback this fixture exercises (registry.subdevices.enumerate_subdevices' per-href probe, issue #205) is what has to find the subdevice instead. The one probes entry, /6c2dff6d-ee5c-dad1-6a5e-000000000001/information/vs/0, is the same real capture already used in airconditioner_fac_bora_2in1_device.json's seed batch (issue #177 comment 5113518087) -- the only href ever actually confirmed to answer under this UUID prefix. No other /6c2dff6d-ee5c-dad1-6a5e-000000000001/* href has been confirmed live yet, so none are seeded here; this fixture's expected outcome is the candidate being found by the flat-href probe but then correctly held back by discover_partitioned's liveness gate (information alone binds no entity), matching where the real issue stands -- not a materialized climate entity, which would require guessing at unconfirmed hrefs. The probe's serialNum (\"TEST-SUBDEVICE-SERIAL-0000\") is a hand-placed placeholder for the real value, not HA's own redaction output -- same placeholder airconditioner_fac_bora_2in1_device.json uses for the identical field."

The seed's /information/vs/0 rep is REAL, verbatim from the reporter's live debug-panel read of /6c2dff6d-.../information/vs/0 (serial replaced with a placeholder) -- modelNum TP2X_FAC_BORA_RAC_21K confirms this is the wall-mounted room subdevice, distinct from the master's floor subdevice TP2X_FAC_BORA_21K. Every other href in this seed batch is CONSTRUCTED (never read from this subdevice) so the subdevice's climate entity has a resource surface to bind -- per DESIGN-177.md section 4, retrieval for this pattern is batch-only, and confirming '/6c2dff6d-.../device/0' actually returns a full batch (as opposed to just answering the information probe the reporter tried by hand) is listed as a follow-up, not something this fixture can attest to."
