MQTT discovery announced ONE device and hung every entity off one unique_id prefix, so at two inverters B's per-unit telemetry had nowhere to go. It has somewhere now, and not one entity that already exists moved. ⚠️ THE ASYMMETRY IS DELIBERATE. The first roster entry's per-unit rows are announced on THE DEVICE IT ALREADY HAS; every later entry gets its own device, via_device the controller. "One device per inverter" is tidier and is the change that renames every entity on the live install - and because HA keeps the id it composed at FIRST discovery, a rename produces a NEW entity beside a DEAD one: the history stays behind and every dashboard, template and automation naming it goes on pointing at a sensor that quietly stopped updating, including the three live watchdog automations. The composed ids come out symmetric anyway (sensor.goodwe_inverter_a_battery_power / ..._inverter_b_...), so the tidy design's only real benefit is bought here without its cost. * four per-unit rows - setpoint, battery power, SoC, SAFETY-02 sign latch - announced only from a roster of two. At N=1 nothing is announced and nothing is published: no second device, no renamed entity, no added topic. * grid and p1_sample_age_s stay SITE-scoped and are announced ONCE, at every roster length 1-6. One P1, one grid connection, and p1_sample_age_s is a watchdog input - a second copy is a second answer to "is the meter fresh?". * inverter.roster_names() is the one answer to what the units are called, read by build_roster() and by the publisher, which must know the roster before a Controller exists because announcing happens on the CONNACK. * DECISIONS/TEL-07-second-mqtt-device.md records the two designs side by side. VERIFIED BY DIFFING THE ANNOUNCED PAYLOADS, not by reading the code. The release/1.0 baseline in test_mqtt.py was generated by running that commit's module, not transcribed. Roster of one: 9 topics, 0 missing, 0 changed, 0 added. Roster of two: 0 missing, 0 changed, 8 added. MEASURED, NOT ASSERTED. Sixteen mutations through tools/mutation_run.sh; twelve are in the file as a running table, each named with the property it breaks. Three of those properties exist because the table found their ABSENCE - dropping the unit from the state topic, moving `grid` into the per-unit set, and `units=()` in main()'s publisher call were all GREEN on the first run, as was a roster fallback naming two nameless entries `inverter-a`. Part 9 enumerates what the file still cannot see, with sizes. ⚠️ INVERTER B DOES NOT PHYSICALLY EXIST (~2026-09-12). Every roster of two here is SIMULATED, from the datasheet and serial in NOTES.md §1.1b. Nothing about B has been measured and no entity described here has been seen on a broker.
