  # ⚠️ 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 SIX FLAT KEYS - `setpoint_entity`, `soc_entity`,
  # `batt_entity`, `batt_invert`, `max_w` and `bms_soc_floor` - 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 six 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
  #       bms_soc_floor: 10
  #     - 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: 4600
  #       bms_soc_floor: 10
  #
  # ⚠️ THE 4600 IS INVERTER B'S DATASHEET FIGURE, NOT A MEASUREMENT AND NOT A
  # PLACEHOLDER. SPIKE-04a (2026-09-04) identified B as a GoodWe GW5048D-ES,
  # serial `55048ESU22AW0992`, whose datasheet gives Max. Charging / Discharging
  # Power as 4600 W; nothing will be connected to its MPPTs, so the battery path
  # is the ceiling and the 5000 VA AC nameplate is not. The 3000 W this example
  # used to carry was a guess made before the unit was known. ⚠️ It is STILL not
  # measured: the datasheet prints 4600 W under BATTERY INPUT DATA, so it may be
  # DC, and `max_w` is graded against 0x0518 - the inverter's own AC power. If it
  # is DC the AC ceiling is nearer 4324 W. SAFETY-20's `min(max_w, dev_max)` is
  # what settles that once the device range is read; see goodwe/NOTES.md §1.1b,
  # which records both readings and picks neither.
  #
  # ⚠️ AND THE `bms_soc_floor: 10` BESIDE IT IS FROM THE SAME PLACE - THE
  # DATASHEET AND THE SERIAL, NOT A PACK ANYONE HAS READ. No second inverter
  # exists on this site (SPIKE-04, ≈ 2026-09-12 for B); the cut-out must be read
  # off the pack that is actually installed (register 0x0560 on the reference
  # unit) before that pack is commanded. It reads 10 here because pack A reads
  # 10, which makes this example DEGENERATE ON THE FLOOR AXIS: a site whose two
  # packs floor at the SAME percent cannot separate `min`, `max`, first or last
  # over the roster, and every SAFETY-32 fixture that DIFFERS the floors differs
  # it for exactly that reason. Do not "simplify" those fixtures to match this
  # example.
  #
  # ⚠️ 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`, `max_w` and
  # `bms_soc_floor` 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".
  #
  # ⚠️ SAFETY-32: `bms_soc_floor` IS PER ENTRY AND IS REQUIRED, NOT DEFAULTED.
  # It is the percent THAT pack's own BMS cuts out at, and two batteries of
  # different models do not share one. A default would be this add-on inventing
  # a cut-out for a battery it has not been told about, which is the same defect
  # as inheriting one: the shallower pack gets protected by a floor that belongs
  # to the deeper pack, and validate.py rule 8 - which refuses a peak_soc_floor
  # the BMS would win against - would be grading the wrong number. Rule 8 grades
  # EVERY entry and names the one it refuses. The flat key below is unchanged and
  # is the single-inverter shape's own cut-out.
  #
  # ⚠️ OPT-09: `capacity_kwh` IS PER ENTRY AND IS OPTIONAL, WHICH IS THE
  # OPPOSITE CHOICE TO `bms_soc_floor` ABOVE AND IS MADE FOR THE SAME REASON.
  # It is THAT pack's usable capacity in kWh, and it is read for exactly one
  # purpose: weighting the SPLIT of the site target between packs by ENERGY
  # headroom rather than by power rating. The two packs here are asymmetric in
  # OPPOSITE directions - 5000 W / 15.36 kWh against 4600 W / 20.48 kWh, from
  # the datasheet and the serials - so a split by rating and a split by energy
  # hand the work to DIFFERENT packs, and the energy one is the question ("which
  # pack can sustain its share for the hour"). A missing cut-out would have to be
  # DEFAULTED, and one default for two batteries protects the shallower pack with
  # the deeper pack's number; a missing capacity has an honest answer instead -
  # this add-on then has NO OPINION about the split and every unit weighs 1.0,
  # which is exactly what shipped before this card. ⚠️ IT IS ALL OR NOTHING
  # ACROSS THE ROSTER: state it on every entry or on none, because a pack
  # weighted in kWh against a sibling weighing a dimensionless 1.0 is not a
  # comparison. There is deliberately NO flat `capacity_kwh` - at one inverter
  # there is no split to weight, so the key would be one an operator can set and
  # nothing reads.
  #
  # ⚠️ 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.

  # no topic and shows no status row.
  #
  # ⚠️ AN HA ENTITY AND NOT A REGISTER, BECAUSE MOST SOLAR INVERTERS ARE NOT ON
  # THIS BUS. The RS485 bus this add-on speaks carries the BATTERY inverter it
  # drives; a household's PV inverter is normally a different box from a
  # different vendor, reporting into Home Assistant through its own integration.
  # So this takes whatever `sensor.*` the site's PV integration provides, any
  # brand Home Assistant can read.
  #
  # ⚠️ POSITIVE IS PRODUCTION, and there is deliberately no `pv_invert` beside
  # `meter_invert` and `batt_invert`. Those two quantities are bipolar AND are
  # read by the control path, so a reversed sensor there is a plausible number
  # the site acts on; production is unipolar and is read by nothing, so a
  # reversed sensor announces itself as -4 kW at noon in the history this key
  # exists to create. See DECISIONS/TEL-11-pv-production.md.

  # is no magnitude heuristic that can tell 30 W of dusk from 30 kW of noon, and

  # The peak guard can COMMAND a discharge to hold a billed quarter under

  # 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.

  # the published lines carry - and the resulting price legitimately goes below
  # zero in the midday hours a PV household exports in.
  #
  # ⚠️ NO STRATEGY IN THIS ADD-ON READS IT. arbitrage.py prices the sell side

  # A JSON object, on one line. You type what your card prints, IN THE CARD'S
  # OWN UNITS; every unit conversion and the VAT multiplication are the
  # add-on's job, because those are exactly the two steps that silently cost a
  # factor of 10, 100 or 1.06.

  #
  # price = (factor x index_eur_per_mwh + offset) x (1 + vat_pct/100), in
  # `units`, converted to EUR/kWh by the add-on.
  #
  # ⚠️ THE `card` BLOCK IS REQUIRED AND IT IS THE SAFETY MECHANISM. Your card
  # prints the formula, the reference index it assumed AND the resulting price.
  # At startup the add-on recomputes that printed price from the numbers you
  # typed and REFUSES TO START unless the two agree to within 0.01 - naming the
  # discrepancy. That catches VAT left out or applied twice, a transposed
  # digit, a unit MISMATCH between the coefficients and the printed price
  # (10x/100x/1000x), and the expensive one: NETWORK CHARGES FOLDED INTO
  # `offset`. A unit error applied to BOTH sides at once cancels out of that
  # comparison; the add-on refuses that separately, by checking the card's own
  # point against the band a Belgian retail tariff can occupy. Your card's formula line is the ENERGY component
  # alone; the add-on adds price_taxes_eur_kwh on top, so folding ~12 c/kWh of
  # network charge into `offset` would bill you for it twice - and it cannot
  # pass, because it moves the computed 15.55 to about 27.
  #
  # ⚠️ AND THE LIMIT OF THAT CHECK, IN THE SAME BREATH: it grades your
  # COEFFICIENTS AGAINST YOUR CARD, not your card against reality. Two numbers
  # copied off the wrong product agree with each other perfectly and pass.
  #
  # ⚠️ FIXED COEFFICIENTS ONLY - the add-on evaluates NO expression of any kind
  # and there is no field that takes one. An unknown key is refused rather than
  # ignored. See DOCS.md for why (it is not only security: two coefficients can
  # be graded against your card and an arbitrary expression cannot be graded
  # against anything).

  # 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

  # 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.

  # ⚠️ A DIFFERENT COMPARISON, NOT A SECOND COPY OF THE ONE ABOVE, AND IT IS

  # the SITE's total command against P1 - one meter, one grid connection. This
  # pair grades EACH inverter's own share against THAT inverter's own measured
  # power (holding register 0x0518), and it catches the fault the meter cannot
  # answer for once there are two units: a unit doing the opposite of what it
  # was told, while its sibling covers for it and P1 reads exactly what a
  # healthy site reads.
  #
  # At ONE inverter these two keys do nothing at all. §6.2's identity makes the
  # site's total command that inverter's command, so the pair above is already
  # asking this question of the same actuator, and arming a second detector
  # would be two latches and two banners for one fault.
  #
  # Both defaults are measured on admin/goodwe's two-master rig, over 1890
  # closed-loop runs in which nothing is faulty, swept across the whole range
  # this file accepts for `gain` and `slew_w`. 250 W is `saturation_w / 2`, so
  # the smallest divergence this can see is exactly the gap at which the control
  # law itself already says the inverter is not following; 85 s is 8.5x the
  # worst legitimate opposition those runs produce (10.0 s), 2.8x the firmware's
  # own 30 s link veto, and under half the 180 s the site check takes. See
  # app/watchdog.py's SIGN_OPTION_DEFAULTS and
  # DECISIONS/SAFETY-30-per-unit-sign.md.
  #
  # ⚠️ unit_sign_disagree_w must stay BELOW max_w, for sign_disagree_w's reason:

  # ⚠️ THE SAME COMPARISON `sign_disagree_*` MAKES, AT THE ROSTER WHERE IT STOPS
  # BEING A STATEMENT ABOUT ONE INVERTER. At two or more units the SUM of the
  # standing commands is graded against P1, and the trip stops the whole site -
  # what it catches is the site being asked for the wrong thing, which every
  # per-inverter check is blind to because each unit is faithfully executing its
  # share. At ONE inverter these two keys do nothing: `sign_disagree_*` above is
  # already asking this of the same actuator.
  #
  # The threshold is the shipped 300 W, CARRIED, and the reason is that the
  # argument behind it does not depend on the roster: near zero the sign is
  # noise, the deadband is 15 W, and there is one P1 whatever is behind it.
  #
  # ⚠️ THE WINDOW IS NOT CARRIED, AND THAT IS A MEASUREMENT. The transient 180 s
  # exists to reject is the loop crossing zero after a load reversal, and the
  # command has to travel the whole SITE rail at `slew_w` per cycle - a rail
  # that is the roster sum while `slew_w` is not. On 1890 two-inverter runs in
  # which nothing is faulty, the worst continuous legitimate opposition at 300 W
  # is 110 s at one inverter and 215 s at two: carrying 180 s across would have
  # shipped a false trip reachable at `gain: 0.05`, `slew_w: 50` and an ordinary
  # 2.2 kW load reversal. 325 s is 1.51x that, inside the 900 s billing quarter,

  # ALARM ONLY. It does not command 0 W and does not latch. A false trip parks
  # the battery; a false notification costs an alert.

  # 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

  # ⚠️ CFG-03. THIS LINE IS THE SOURCE OF TRUTH FOR THIS DEFAULT, and
  # `app/delivery.py`'s `DELIVERY_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_delivery.py pins the copy by READING this line, so a
  # drift goes red in CI rather than shipping. Two places - options:, schema: -
  # plus that one dict, and no fourth.
  #
  # ⚠️ THERE IS NO `delivery_w` TO GO WITH IT, AND THAT IS DELIBERATE. The watts
  # half of this check is `saturation_w`, the option two blocks down, read
  # directly: it is already the gap at which the control law itself concludes
  # the inverter is not following, and a second key would be a fourth place a
  # threshold has to be kept in step and a way for the two to disagree. So
  # RAISING `saturation_w` raises this check with it, and test_delivery.py part
  # 4b holds that promise by running the same fault at two different
  # `saturation_w` values and requiring two different answers - a check that
  # only ever ran at 500 could not tell this wiring from a hard-coded number.
  #
  # How long ONE inverter may stand at a discharge share it is not producing -
  # short by more than `saturation_w`, OR short by more than a fixed FRACTION
  # of its own share (SAFETY-43; the fraction is derived and is not an option,
  # see app/delivery.py) - while at least one sibling is NOT in that state,
  # before the add-on names it. It REPORTS: nothing is commanded
  # differently, the loop is untouched, and the site goes on running short by
  # that unit's share until somebody looks. app/delivery.py carries why, with
  # the rig measurements on both sides of the decision.
  #
  # Ignored at one inverter, where the check is inert by construction: with no
  # sibling, "this box cannot deliver" and "this plant cannot deliver" are the
  # same observation.
  # ⚠️ MEASURED ON THE TEST-19 TWO-MASTER RIG, NOT CHOSEN. 2640 closed-loop runs
  # at a roster of two in which nothing was faulty, over 6 gains x 5 slews - the
  # whole range this schema accepts - across load reversals, a flapping load and
  # ASYMMETRIC SPLITS, plus a roster-of-ONE arm as the control. At the shipped
  # threshold the worst CONTINUOUS legitimate episode is 35.0 s (the weighted
  # family; 30.0 s on reversals, 0.0 s on flapping, and 0.0 s at every threshold
  # in every one-inverter run). 185 s is 5.29x that.
  #
  # ⚠️ AND THE CAMPAIGN IS RE-RUNNABLE NOW, WHICH IT WAS NOT WHEN THIS NUMBER
  # SHIPPED. TEST-21 (2026-09-07) committed the harness to the OTHER repository,
  # `admin/goodwe:sim/delivery_window.py` - it imports plantsim and frame_check,
  # which that repo owns. From clean checkouts of both, side by side:
  #
  #     cd goodwe/sim && GOODWE_ADDON_REPO=/path/to/goodwe-addon \
  #         python3 -B delivery_window.py --selftest --campaign --blag
  #
  # ⚠️ THE ORIGINAL RECORD SAID 30.0 s AND IT DID NOT REPRODUCE - the re-run
  # says 35.0 s. 185 s still clears all four bounds and is unchanged; what
  # changed is the claim. DECISIONS/SAFETY-42-unit-delivery.md §3.3 carries both
  # tables and what did and did not reproduce.
  #
  # ⚠️ AND THE MARGIN IS A SENSITIVITY STUDY ON A HYPOTHESIS, NOT A MEASUREMENT,
  # BECAUSE INVERTER B DOES NOT PHYSICALLY EXIST (~2026-09-12). The rig's B is A
  # COPIED. Sweeping a DIFFERENT second unit through that campaign: the worst
  # legitimate episode barely moves with B's ramp (35.0 s at half A's ramp) and
  # scales with its LAG - 45.0 s at twice A's measured 10 s lag, 75.0 s at four
  # times it. 185 s is 2.47x even the four-times-slower case. NO NUMBER HERE IS
  # A MEASUREMENT OF INVERTER B.

  # and not 150 or 200. 37 control cycles.

  # SAFETY-10. Run the whole decision path and command NOTHING - strategies,
  # arbiter, clamps and guards all run, the decision and its reason are
  # recorded, and every inverter is held at 0 W. `app/shadow.py` carries the
  # argument; the three things to know before changing this line are:
  #
  #   auto  shadow WHILE CONTROL IS STOPPED, live once it is started. This is
  #         the shipped value and it is what "default-on" means here.
  #   on    always shadow, whatever the Start / stop button says. This is the
  #         one an operator picks to watch a day of decisions on an armed site
  #         before letting it trade.
  #   off   ordinary control.
  #
  # ⚠️ IT IS NOT A BOOLEAN DEFAULTING TO `true`, AND THAT IS THE WHOLE CARD.
  # The Supervisor composes an add-on's options as `{**these defaults, **the
  # stored user options}`, so a NEW key with a new default reaches every
  # EXISTING install on the next update - including one regulating a real
  # battery. `shadow_mode: true` would silently stop it, and the only symptom
  # would be a battery that has stopped doing anything. There is no mechanism
  # in this options system that lets one key default differently for a new
  # install and an existing one, so "default-on for new" has to be a value the
  # add-on RESOLVES. `auto` is that value: a fresh install ships
  # `auto_start: false` and therefore comes up in shadow mode; an install that
  # is controlling is started, so `auto` resolves to live and NOTHING about it
  # changes.
  #
  # ⚠️ AND UNDER `auto` THE START BUTTON LEAVES SHADOW MODE. Pressing *Start /
  # stop control* is the operator saying "control the battery". Somebody who
  # wants the decisions recorded WHILE the loop runs sets `on` explicitly -
  # which is the configuration this option exists for, and the one that cannot
  # be reached by accident.

  # ⚠️ SAFETY-39. 0 IS NOT "UNSET" AND IT IS NOT "NO LIMIT" - IT IS "FOLLOW THE
  # RAIL", and it is the shipped value. `control.slew_limit_w()` resolves it to
  # `SLEW_RAIL_FRAC * max_w`, which is 222 W against the 2000 W default here,
  # 556 W against the live install's 5000 W, and 1067 W against the ~9600 W a
  # second inverter makes of the site. `integrator_max_w: 0` two lines down has
  # meant exactly this since it was added; this key now means it too.
  #
  # ⚠️ WHY IT IS A RATIO AND NOT A NUMBER, WHICH IS THE WHOLE OF THIS CARD. It
  # WAS a number: 1000, derived 2026-08-22 against a clamp of 1500 W
  # (goodwe/NOTES.md, "Simulated 2 kW load step (gain 0.6, clamp 1500)") on the
  # grounds that it caps "how far the loop can jump ahead of the inverter". The
  # rail then went to 5000 on the live install and the constant did not move, so
  # 1000 W per 2 s tick crossed the whole output range in 10 s against a plant
  # NOTES.md §5.10 measured at ~18 s up / ~23 s down. Measured on the owner's
  # system 2026-09-05 11:43-11:46: a 3.4 kW export drove the setpoint 380 -> 5000
  # in five ticks, the battery to -5154 W past a 5000 VA rating, and the grid
  # from 3.4 kW of EXPORT to 2.8 kW of IMPORT. Large (>= 900 W) steps per 30 min
  # went 2 -> 1 -> 13 -> 43 that morning. Nothing was broken; the rail moved.
  #
  # An explicit number is still accepted and is not clamped - the live install
  # has run 400 since 2026-09-05 12:00, which is slower than the rail implies
  # and is fine. What validate.py rule 10 refuses is a number FASTER than the
  # rail implies, because at that setting the stated limit is not the limit and
  # the layer that overrules it is the plant, which has no status row.
  #
  # ⚠️ AND THE COST IS REAL AND IS NOT HIDDEN: following the rail is slower to
  # converge than 1000 was. Measured over 51 export steps on the in-repo model
  # (test_control.py) the largest tick step falls from 1000 W to 556 W and the
  # >= 900 W step disappears from every run - but the OVER-ABSORPTION does not
  # move, because that is a `gain` term and not a slew term. See

  # ⚠️ THREE OF THESE FIVE IDS NO LONGER RESOLVE TO A PLUGIN, AND LEAVING THEM
  # HERE IS A DECISION (TARIFF-07). engie_dynamic, totalenergies_dynamic and

  # the obvious edit is to delete them from this line too. DO NOT. The Supervisor
  # validates the options file against this schema BEFORE the add-on starts, so

  # operator gets an opaque "expected one of ..." from the Supervisor, the add-on
  # never runs, and validate.py's retired-id refusal - the message that tells
  # them their prices never worked and what to do instead - IS NEVER REACHED, on
