  # --- ARCH-01 / CFG-04: the inverter roster ---------------------------------
  # ⚠️ EMPTY IS NOT "UNCONFIGURED", IT IS THE SINGLE-INVERTER CONFIGURATION, and
  # it is what every install that upgrades into this version lands on. An empty
  # list means THE FIVE FLAT KEYS ABOVE DESCRIBE THE ONE INVERTER - same
  # entities, same rating, same behaviour, no operator action - which is the
  # only migration story this key was allowed to have. `build_roster()` reads
  # this and nothing else decides the shape.
  #
  # Declared, it REPLACES those five keys rather than extending them. Each entry
  # names its own actuator, its own rating and its own sensors:
  #
  #   inverters:
  #     - name: inverter-a
  #       setpoint_entity: number.goodwe_a_setpoint_w
  #       soc_entity: sensor.goodwe_a_soc
  #       batt_entity: sensor.goodwe_a_battery_power
  #       max_w: 5000
  #     - name: inverter-b
  #       setpoint_entity: number.goodwe_b_setpoint_w
  #       soc_entity: sensor.goodwe_b_soc
  #       batt_entity: sensor.goodwe_b_battery_power
  #       max_w: 3000
  #
  # ⚠️ NOTHING IS INHERITED FROM THE FLAT KEYS BY AN ENTRY THAT OMITS IT, and
  # that is the whole of DEV-02 restated as a config rule. `soc`, `batt` and the
  # rating became per-instance precisely so that no inverter is ever graded
  # against a sibling's numbers; an entry silently inheriting `soc_entity` would
  # rebuild that defect in YAML. `name`, `setpoint_entity` and `max_w` are
  # therefore REQUIRED of every entry (the schema below enforces it, and
  # validate.py rule 9 enforces it again for the callers the Supervisor never
  # sees). An omitted `soc_entity`/`batt_entity` means THIS UNIT HAS NO SUCH
  # SENSOR - `inputs_ok` already stops the site for that - and never means
  # "use the other one's".
  #
  # ⚠️ AND THE FLAT `setpoint_entity` MUST THEN BE BLANK. Leaving it set while a
  # roster is declared is two config sites aimed at actuators, one of which
  # nothing writes; if it names an entity an entry also names, SAFETY-28's
  # writer census refuses it as two writers on one actuator, and if it names a
  # different one the add-on would run a site quietly smaller than the config
  # reads. Rule 9 refuses both rather than picking one.
  #
  # ⚠️ THE SHAPE WAS MEASURED, NOT ASSUMED. A list of objects is not used
  # anywhere else in this file, and whether Supervisor's options validator
  # accepts one was an open question - `static_profile` carries its structure as
  # a JSON string in a `str?` for exactly that doubt. It was settled by running
  # Supervisor 2026.08.0's OWN `AppOptions` validator (the version this site
  # runs) against both candidates: tools/supervisor_shape_probe.py is the
  # script, DECISIONS/CFG-04-inverter-roster.md is what it printed and why the
  # list won. The default `[]` is load-bearing in that record: WITHOUT it the
  # validator answers `Missing option 'inverters' in root` for every existing
  # options blob, and the upgrade leaves an add-on that cannot start.

  # --- P1 meter ingestion (specs §5.2 / §14 `meter:`) -------------------------
  # `off` keeps the original single meter_entity path above, so an existing
  # install is untouched until it opts in. ha_dsmr subscribes to the DSMR
  # integration's entities over the HA WebSocket; mqtt_p1 reads the topic below;
  # ha_signed reads ONE signed HA entity (+ import / - export), which is what a
  # HomeWizard P1 publishes and what ha_dsmr cannot consume.
  # homewizard_local skips Home Assistant entirely and polls the meter's own
  # local API. ⚠️ It is the ONLY mode whose sensor.p1_sample_age_s measures when
  # the meter REPORTED rather than when the value last CHANGED - HA emits
  # nothing at all for a repeated reading - so it is the only mode a firmware
  # watchdog may threshold. See DOCS.md.

  # Trips when the emitted setpoint and the P1 net figure point OPPOSITE ways,
  # both over sign_disagree_w, continuously for sign_disagree_s. Action: 0 W and
  # a failsafe that latches until an operator starts control again.
  #
  # Both defaults are measured, not chosen. On the captured healthy day
  # (2026-08-23) the longest legitimate opposed run - a load step the loop has
  # not caught up with - is 30 s, and sign agreement over the gated samples is
  # 93.4 %. On the captured fault day (2026-08-20) the clusters run 0.0-10.5 %
  # agreement with opposed runs up to 1752 s. 300 W / 180 s sits in the middle of
  # a very wide gap: at 60 s the healthy day still trips nothing, at 300 s the
  # fault day still trips 13 times. There is no reason to move either number
  # without a capture that says so. They are options because the AC says
  # thresholds are defaults rather than constants - not because they are knobs
  # anyone is expected to turn.
  #
  # ⚠️ sign_disagree_w must stay BELOW max_w or the watchdog can never fire (the
  # arbiter bounds the command to +-max_w). validate.py refuses that config.
  sign_disagree_w: 300
  sign_disagree_s: 180

  # --- SAFETY-18 frozen-but-fresh meter detector -----------------------------
  # Seconds the meter may keep answering with an UNCHANGED measurement while the
  # command stands at the rail before the add-on raises an alarm. Both halves
  # are required: neither one alone is safe, and app/freeze.py carries why.
  #
  # ALARM ONLY. It does not command 0 W and does not latch. A false trip parks
  # the battery; a false notification costs an alert.
  #
  # ⚠️ Only `meter_source: homewizard_local` can see this at all - it is the
  # only transport that reads the meter's own document. On every other source
  # the status page says NOT COVERED rather than "armed".
  #
  # 300 s is measured, not chosen. Over 2399 s of the live house at the
  # converged operating point (sim/scenarios/p1-age-2026-08-26.jsonl.gz, mean
  # grid -14.2 W, 1194 polls, 735 of them repeating the previous reading) the
  # LONGEST run without a distinct reading is 15.4 s (the largest unchanged_s any
  # sample observes is 8.0 s). 300 s is 19.5x the pessimistic figure, and
  # still inside the 900 s quarter that bills the capacity tariff.
  meter_freeze_s: 300

  # --- SAFETY-31: circulating power ------------------------------------------
  # ⚠️ CFG-03. THESE TWO LINES ARE THE SOURCE OF TRUTH FOR THESE DEFAULTS, and
  # `app/circulation.py`'s `CIRC_OPTION_DEFAULTS` is the ONE in-code copy - the
  # Dockerfile does not put this file in the image, so the running add-on cannot
  # read it. test_watchdog.py pins the copy by READING these lines, so a drift
  # goes red in CI rather than shipping. Add a third option in three places -
  # options:, schema:, CIRC_OPTION_DEFAULTS - and in no fourth.
  #
  # Circulating power is sum(|Bi|) - |sum(Bi)| over MEASURED per-inverter power:
  # two inverters pushing against each other, which NETS TO ZERO AT THE METER
  # and is therefore invisible to every other guard in this add-on. Both numbers
  # below were measured on the TEST-19 two-master rig over 924 closed-loop runs
  # in which nothing was faulty; circulation.py carries the curve they were read
  # off and the argument for each. They are NOT sensitivity preferences.
  #
  # Both are ignored at one inverter, where the quantity is identically zero.
  circulation_w: 700
  circulation_hold_s: 75

  # --- maintenance -----------------------------------------------------------
  # ⚠️ CFG-03. THESE EIGHT LINES ARE THE SOURCE OF TRUTH FOR THE MAINTENANCE
  # DEFAULTS. The Supervisor reads this file and the operator edits this file,
  # so nothing else in the add-on gets an opinion about what a missing
  # `maintenance_*` key means. There is exactly ONE in-code copy -
  # `app/maintenance.py`'s `MAINT_OPTION_DEFAULTS` - because the Dockerfile does
  # not put this file in the image and the running add-on therefore cannot read
  # it; test_maintenance.py pins that copy by READING these lines, so a drift
  # goes red in CI rather than shipping. main.py and validate.py both read the
  # mirror and type no number of their own.
  #
  # Before this card the same defaults were written down three times and had
  # already disagreed: this block said 2000 while main.py and MaintConfig said
  # 2500, so an options dict with the key ABSENT passed validation at 2000 and
  # then ran at 2500 against a 2000 W ceiling - a silent 0 W arbiter
  # contradiction. Changing one of these numbers now moves every consumer.
  maintenance_enabled: false
  maintenance_interval_days: 28
  maintenance_start_hour: 10
  # ⚠️ BOTH MUST STAY AT OR BELOW max_w, and that is why they are 2000 rather
  # than the 2500 they shipped as. The cheap-window charge shaping asks the
  # arbiter for `hi = -maintenance_charge_w` against the supervised `lo =
  # -max_w`: above the ceiling that is `lo > hi`, a contradiction resolved to
  # 0 W, so maintenance would SILENTLY NEVER CHARGE in a cheap window on a
  # default install. validate.py refuses that config (rule 6), so these
  # defaults had to become self-consistent with the max_w above rather than
  # ship a configuration the validator rejects.
  #
  # The discharge side is clamped rather than contradicted - it drains at max_w
  # and the arbiter says so - so it is only warned about; it is 2000 here for
  # symmetry and to keep the shipped config warning-free.
  #
  # Raising max_w (the live reference install runs 5000) is what unlocks a
  # faster maintenance cycle. Raise max_w FIRST, then these.

  # --- tariff / capacity tariff (all optional) ------------------------------
  peak_forecast_entity: ""
  peak_cap_w: 3500

  # --- SAFETY-24: the energy backstop under SAFETY-07's forced discharge -----
  # The peak guard can COMMAND a discharge to hold a billed quarter under
  # peak_cap_w. Until this card it was bounded from below by nothing but the
  # pack's own BMS cut-out - a real floor, but the PACK's protection rather than
  # the OPERATOR's. On the 2026-08-20 replay the guard asks for 878 Wh in a day.
  #
  # peak_soc_floor is the percent below which that discharge is not sized. When
  # it binds the guard reports FLOOR-LIMITED, keeps charging blocked (a 0 W
  # floor), and the add-on raises ONE notification saying the quarter will be
  # exceeded - failing to shave is never silent, because the euro figure is the
  # whole point of the guard.
  #
  # ⚠️ THIS IS NOT maintenance_soc_floor AND MUST NOT BE MERGED WITH IT.
  # maintenance_soc_floor is the DRAIN TARGET of the monthly recalibration: the
  # depth the cycle deliberately goes to, once a month, on purpose. This is the
  # depth a money-saving discharge may never reach on any day. The right values
  # differ, and sharing one key would couple two features that want to move
  # independently.
  #
  # ⚠️ 20 IS DERIVED, NOT PICKED. The reference pack is 13.8 kWh usable and the
  # worst modelled guard day is 878 Wh, i.e. 6.4 % - so 10 points above the
  # pack's own cut-out leaves the guard ~1.6 of its worst observed days of room
  # and still never reaches the BMS.
  #
  # ⚠️⚠️ SAFETY-25 - WHAT THIS DOES NOT BOUND, AND IT IS THE HALF THE NAME HIDES.
  # peak_soc_floor BOUNDS THE PEAK GUARD ONLY. IT IS NOT A PACK-WIDE RESERVE.
  # Ordinary self-consumption - the grid-following loop that holds the meter at
  # zero - has no SoC floor of any kind, so on a sustained-load evening it will
  # discharge STRAIGHT PAST this number and go on until the pack's own BMS
  # cut-out (bms_soc_floor) stops it. Replayed on the committed 2026-08-20
  # capture, 19:00-22:00 UTC: a 13.8 kWh pack starting at 21 % ends the evening
  # at 10.0 %, and 343 of 587 control cycles deliver discharge with the pack
  # already below this floor. Setting this key higher does not change that by
  # one tenth of a percent - the same replay at every value the schema accepts
  # (5..60) ends at the same 10.0 %.
  #
  # The reason is structural, not an oversight: the peak guard files a `lo`
  # limit (a LOWER bound on the setpoint), which is what makes it provably
  # unable to cap a discharge or contradict the arbiter - and therefore also
  # unable to stop one the loop itself wants. See peakguard.py's module note and
  # DECISIONS/SAFETY-25-loop-soc-floor.md, which records the options for a
  # loop-side reserve and is waiting on the product owner. Until that is
  # answered, the BMS is the only floor under self-consumption.
  peak_soc_floor: 20
  # The pack's OWN cut-out percent - what the BMS enforces whatever is set
  # above. Register 0x0560 reads 10 on the reference GW5000S-BP, consistent with
  # DoD 90. It is here so validate.py can REFUSE a peak_soc_floor at or below
  # it: such a floor can never bind, the BMS wins, and the status page would
  # report an energy backstop that does not exist.
  bms_soc_floor: 10

  # ⚠️ THE OLD PRICE PATH, AND IT IS NOT DEAD YET. These two entities are the
  # add-on delegating the whole price question to Home Assistant: main.py reads
  # both and derives ONE BOOLEAN, `cheap = now <= avg`, which is consumed by
  # nothing except the maintenance cycle's cheap-window charge floor. That is
  # all they have ever done. They are kept, because retiring them would take
  # the maintenance cycle's only price signal away on a live install before
  # anything replaces it - TARIFF-03 (static profile) and OPT-04 (arbitrage)
  # are the cards that replace it, and neither has landed.
  #
  # ⚠️ They may NOT be combined with price_provider below. Two price sources on
  # one site, one of which silently wins, is exactly the "double up" the PM
  # named; validate.py rule 7 refuses that configuration at startup rather than
  # letting an operator believe the provider they configured is driving
  # something. See app/validate.py.

  # --- price arbitrage (OPT-04, specs §10.1 priority 3 / §17) ---------------
  # Charge in the cheapest published hour, discharge in the dearest, and ONLY

  # against the meter on purpose, so it is armed deliberately or not at all.

  # ⚠️ IT NEEDS A PRICE SOURCE AND A P1 METER, and validate.py refuses the
  # combinations that cannot work rather than letting them look armed. With

  # on; with `meter_source: off` the capacity-tariff peak guard never runs, and
  # §9.1 puts peak shaving above arbitrage - a charge nothing measures is the
  # exact failure that guard exists to prevent.
  #
  # ⚠️ AT THE SHIPPED THRESHOLD A STATIC DAY/NIGHT SITE DOES NOT TRADE. The
  # realistic Belgian day/night spread is about 0.08 EUR/kWh and the threshold
  # below is 0.10, so the verdict is "the firm spread does not cover this
  # cycle's cost" and nothing happens - correctly. That is a product decision
