glenn schrooyenandClaude 9ac3a9d2bc PRICE-01: price_service provider, fallback chain, and the gate read from it
checks / unit (pull_request) Successful in 39m31s
infra-pin / fresh (pull_request) Successful in 1s
A new price source, `price_provider: price_service`: the owner's price server,
one fixed HTTPS host, a bearer token (new password option
`price_service_token`), wholesale energy only so markup and taxes are added as
for generic_dayahead.

The chain is server, then energy-charts, then the prices the history store
kept. A step counts only if it has a price for now. Each step down and back up
is one log line. With every source down a site plans from what it saved.

No price for now: one status row, one Home plan line and one notification, in
English and Dutch, cleared when a price returns. With this provider the
maintenance charge gate reads the provider's prices and keeps the Home
Assistant rule: the current 15-minute price is at or below today's average.

The token is hidden on the settings page, refused when missing, and taken out
of any error text. Other providers, `off` and the Home Assistant pair take the
road they always took (scripted-day probe against 0ce7d35: one line differs,
the refusal that lists the known providers). See
DECISIONS/PRICE-01-own-price-server.md.

glenn schrooyenandClaude Opus 5.5 9b1fa758ad OPT-17: the solar forecast can come from several entities, summed
checks / unit (pull_request) Successful in 36m13s
infra-pin / fresh (pull_request) Successful in 1s
New list options pv_forecast_entities and pv_forecast_tomorrow_entities
(same shape as pv_entities); the single-entity keys are unchanged.

- Each member is read in its own unit (Wh/kWh/MWh) in one gather and the
  day is summed. Hourly splits are merged when every member has one, else
  the total goes on the bell.
- A member missing, unavailable, stale, non-energy or bad makes that
  day's forecast unusable (no partial sum). A caution row names it by
  position; the action log names the entity once per change.
- Single key and list both set for one day: refused at start.
- A one-member list behaves exactly like the single key (test_opt17.py);
  the single-key path is byte-identical to e36565f over 24 scenarios.
- Supervisor shape measured: tools/supervisor_shape_probe.py section J.

DECISIONS/OPT-17-several-forecast-entities.md has the rules.

goodwe-agent 02c0a3dd7b MAINT-10: maintenance start hour in local time, default 19:00
The start hour was compared with the UTC hour, so the shipped 10 started at
12:00 in a Belgian summer. It is now read in Home Assistant's time zone
(fallback: the container's TZ, then UTC, one log line says which), and the
default moves to 19. DST: a missing hour starts at the first hour after the
jump; a repeated hour starts only in its first pass. Stored options are not
rewritten: a saved 10 now means 10:00 local (DOCS, CHANGELOG).

Claude eb10537aee OPT-11 P4: solar forecast and day plan
A Home Assistant solar forecast (Forecast.Solar, Solcast or Open-Meteo
shapes) and the add-on's own hourly house use decide, before each cheap
run, whether the sun will fill each battery before the expensive hours.
Leftover solar then buys from the grid only the shortfall; Cheap hours only
skips the part the sun covers; Solar first never grid-charges. No, stale or
failed forecast: P3 option A exactly (12 digests pinned from 5a4cdc2).

Replay (16 recorded days, forecast errors from Elia's day-ahead BE solar):
year-earlier prices P4 19.15 vs P2 19.33 / option A 19.44 / old trade 18.14;
real 2026 prices P4 29.19 vs 32.26 / 32.01 / 31.40 EUR net.

glenn schrooyenandClaude Opus 5.5 7c4c8f5c66 SAFETY-79: peak guard keeps a margin below the limit
checks / unit (pull_request) Failing after 11m34s
infra-pin / fresh (pull_request) Successful in 1s
New option peak_margin_w (default 50 W, 0-500 W). The peak guard, the
forecast checks and the maintenance charge sizing aim at
peak_cap_w - peak_margin_w; the month peak, the bill, headroom, warnings
and every notice keep the real cap. Owner decision 2026-09-28.

peak_margin_w 0 is byte-identical to ed739d4 (tools/safety79_identity.py,
test_peak_margin.py part 1). validate.py rule 12 refuses a value outside
0-500, not whole, or not below the peak limit.

Claude dev agent d69fd8fbfd OPT-11 P1: per-battery mode limits, on/off, solar order
checks / unit (pull_request) Successful in 10m59s
infra-pin / fresh (pull_request) Successful in 1s
A battery's mode is a soft unit limit (source `mode`, P_MODE 35) kept
apart from the hard limits in pre_resolve(). The allocator applies it
only while the site target is decided at or below 35 (new
Resolution.deciding_priority), so the peak floor releases it and a mode
`hi` never meets the site `lo`. At N=1 resolve() applies the same rule
to the site target after stage 2. A mode range without 0 W is dropped
as a software fault, so REFUSE_SIGN stays unreachable from a mode.

compute() gets the loop bound (sum over live units of hard limits with
modes applied), so the loop never asks for watts no battery may give
and the saturation freeze never parks on them. While charging, Leftover
solar weighs 0 so Solar first fills first. Store keys pack_use and
pack_mode per battery, set by two new /action values; Off stops and
skips maintenance with a log line. Minimal Batteries cards (EN/NL).

Off by default (battery_modes_enabled); off, commands are byte-identical
to a5dddad at N=1 and N=2 (test_modes.py part 1).

glenn schrooyenandClaude Opus 5.5 7559d21eda TEL-14: PV sign declared per entity (pv_invert_entities)
checks / unit (pull_request) Successful in 8m39s
Some PV entities (kWh meters, ESPHome clamps in the PV circuit) read positive
for consumption and negative for production. `pv_invert_entities` lists the
ones to flip; the flip is applied per member inside pv.total(), before the sum,
so the MQTT `pv` row and the status page carry the corrected figure. Default []
is byte-identical to 0.12.0.

Shape measured in supervisor_shape_probe.py section H (Supervisor 2026.08.0):
a parallel list validates the 0.12.0 blob unchanged and renders as its own
translated repeatable field; dicts on pv_entities refuse 0.12.0's stored
strings; a prefix is invisible syntax; a global bool cannot describe a mixed
roster. Status page marks flipped entities and cautions per entity below
-50 W, saying ADD or REMOVE. Telemetry only: control documents unchanged.

Record: DECISIONS/TEL-14-pv-sign.md (reverses TEL-11 section 2).

- DOCS.md / config.yaml: the watchdog's P1 age entity is
  sensor.goodwe_p1_sample_age (device "GoodWe" + "P1 sample age", as

  sensor.p1_sample_age_s.
- DOCS.md: the inverters: example and per-entry table carry the required

  required keys, not three.
- Field guide: marked v0.1.0/outdated; slew_w row no longer recommends the
  1000 W that SAFETY-39 now refuses. HTML regenerated; the PDF is NOT
  rebuilt (no Chrome here). README/DOCS pointers fixed.
- test_docs.py: the documented roster must pass app/validate.py and the
  schema's per-entry keys; the documented entity id must equal the id
  composed from app/mqtt.py; the wrong id may appear in no shipped doc.

adminandClaude Opus 5 0ef9565071 TEL-12: several PV inverters, and one absent member is an absent TOTAL
checks / unit (pull_request) Successful in 7m59s
0.11.0 shipped `pv_entity` as a single string. The reference site's owner
reported within minutes of it going live that they have several PV inverters
and could configure one - which is ordinary for a multi-string roof, not a
property of one house. `pv_entities` is the roster and the row carries the
SITE total.

⚠️ THE HARD PART IS ABSENCE, NOT THE LIST. Three configured, one `unavailable`,
and the sum of the other two is a SMALLER NUMBER INDISTINGUISHABLE FROM A REAL
ONE. Read back by OPT-10 that says "there was less PV than there was" - the "no
irradiance" conclusion the channel exists to TEST. So `pv.total()` answers
`None` the moment any configured entity is absent: the topic carries HA's own
`None`, the entity goes to `unknown`, the recorder records a GAP. The
alternative (the partial sum beside a contributor count) was implemented and
run as mutation N1b; it loses because the MQTT row is read COLD a week later by
an attribution that would believe it, while the qualifying count would live in a
second entity with its own history. The partial information is not thrown away -
the STATUS PAGE names every entity that reported, with its watts, and every one
that did not, with its reason, because that surface is read LIVE by a human who
wants the diagnostic.

⚠️ AND THE MIRROR: a member honestly reporting 0 W is SUMMED. The test is
`is None`, never falsiness - a roster that blanked the site on a zero would
report an absence on every clear evening.

THE SURFACE IS MEASURED, NOT PREFERRED. `pv_entity` could not become a list:
tools/supervisor_shape_probe.py §G shows Supervisor 2026.08.0 answering an
0.11.0 install's stored string with `Invalid list for option 'pv_entity'`, and
deepmerge's list strategy is `override` so a `[]` default does not rescue it -
the live add-on would not start. `match(.*)?` does accept both shapes and is
rejected for a different, measured reason: it validates nothing (a string, a
list and the integer 417 all pass) and renders as a plain text box. So
`pv_entities` joins `pv_entity` and REPLACES it when set, CFG-04's rule for
`inverters:`, with a status caution saying which key won - a union would
double-count the inverter the old key still names.

STILL NOT A CONTROL INPUT. tools/tel11_pv_trace.py was extended rather than
replaced and now grades five claims over three document sets. The control hash
is UNMOVED - 846a10a5b89e… on `unset` and on `one`, on both trees - and the
roster control document is byte-identical between the two trees. 2/5 is a claim
TEL-11 could not make: with 0.11.0 as the baseline, "one entity behaves exactly
as 0.11.0 does" is a real cross-tree identity over control AND telemetry.

⚠️ TEL-11's OWN `--compare` REFUSAL HAD TO CHANGE, and that is MUTATION.md habit
24: a discriminator defined as "the baseline lacks this feature" dies on the
release that ships the feature, and dies as a false refusal.

Twelve mutations, each on a fresh purged `cp -a`, no survivors. N5 is +0 B
(`sum` -> `max`, the same three characters) and was run on a fresh copy with
`cmp` confirming the edit on disk. The fixture is three distinct NON-ZERO
contributions in two units with absence driven at EVERY position - a member
contributing 0 W could go absent without moving the sum of the rest, which is
habit 23 with a coinciding value in the arithmetic rather than in the plant.

31/31 in the CI image. Not deployable as merged: config.yaml stays at 0.11.0,
so predeploy_check.py reports a NO-OP until PKG cuts a version. A CHANGELOG
entry is wanted and deliberately not written - 11b forbids `## Unreleased` and
the bump is PKG's call; DECISIONS/TEL-12-several-pv-inverters.md is the
material it needs.

adminandClaude Opus 5 cfafdffaed PKG-17: cut 0.11.0, so SAFETY-56's wording fix and TEL-11's pv_entity can reach an installed 0.10.1
checks / unit (pull_request) Successful in 8m0s
Two files, and no third. config.yaml 0.10.1 -> 0.11.0; CHANGELOG.md gains
`## 0.11.0` and three corrections to sections below it.

A MINOR BUMP, NOT A PATCH. TEL-11 adds an option - `pv_entity`, 75 keys -> 76 in
`options:` and `schema:` together - which is the same test 0.8.0, 0.9.0 and
0.10.0 were cut on. Nothing here can refuse a stored blob: the key is `str?`
with an `options:` default of "", validate.py does not mention it, no default
moved and no enum widened, so a blob that starts the add-on on 0.10.1 starts it
on 0.11.0.

THE TABLE HAS TWO ROWS AND THE WINDOW HAD FOUR MERGES. CI-9's follow-up
(9f6b9f1, `.gitea/workflows/checks.yml` only) and SEC-2 (239e120,
`docs/RELEASE.md` + README.md) are excluded under PKG-15's rule - AUDIENCE, NOT
IMPORTANCE. Neither file is under `goodwe_controller/`, neither is in the built
image, neither is in predeploy_check.py's RUNTIME tuple, and there is no version
of this add-on on which an operator can observe either. SEC-2 is the closer call
and the section argues it in full rather than asserting it: it is the more
consequential ticket of the two - it is why this release is a pull request
rather than a push to master - and it is still a procedure for whoever cuts a
release, not something the person deciding whether to press Update can act on.
Both are named in the section with pointers to PR #102 / checks.yml and PR #108
/ docs/RELEASE.md.

WHAT THE ENTRIES LET AN OPERATOR DECIDE. SAFETY-56: behaviour byte-identical
(6030175ed2ab..., reproduced in the CI image over 2390 capture reads, a 66-cell
grid stepped 120 times and six driven worlds), three surfaces named with the old
and new wording side by side - the STALE_READING line quoted onto the action log
and status page, the SAFETY-37 ERROR log line, and the readiness row that
asserted a false fact about a named entity. TEL-11: unset is byte-identical in
BOTH the control and telemetry documents, set is byte-identical in the control
document only; the three TEL-11 rows of that table were re-measured in the CI
image on this tree (control 846a10a5... twice, telemetry a443a6ce... / 4e6d1cb2...).
It is stated plainly that pv_entity is not a control input and does not change
what the loop does, and that absence publishes `unknown` rather than 0.

THREE CORRECTIONS BELOW THE NEW SECTION, WITHOUT REWRITING HISTORY. The 0.10.1
preamble said SAFETY-56 was open; the SAFETY-57 entry said its accusatory
diagnosis half was "deliberately untouched"; the 0.10.0 preamble left SAFETY-56
with no pointer while SAFETY-57 had one. All three quotations are what the
0.10.1 image actually prints and are left standing - a reader on 0.10.1 has to
recognise them - each now scoped to 0.10.1 and pointed at `## 0.11.0`.

VERIFIED. test_version_gate.py part 11 all four: 11a one contents table and the
slicer closed (302 lines under '0.11.0'), 11b 0.11.0 == config.yaml, 11c all
three RETIRED_PROVIDERS ids named - scoped to a pre-0.10.0 crossing and pointing
at `## 0.10.0`, which is where the evidence is - 11d still exactly one
`## Unreleased` below, PKG-08's, untouched. 31/31 in the CI image, checks.yml's
exact command, purged tree, `:ro`.

Not deployed and not installed. Shipping is a separate pull request from
release/1.0 into master, per docs/RELEASE.md.

glenn schrooyenandClaude Opus 5 07ba3433ed TEL-11: PV production stops being invisible, and stays out of the control law
checks / unit (pull_request) Successful in 8m6s
OPT-10 measured that this site's pack reaches 90 % SoC on 2 days of 16 and that
20.5 kWh of surplus left the site while the pack had room - 12.6 kWh of it with
the battery not charging at all - and could not say WHY, because PV production
is recorded NOWHERE. Three causes need three different fixes (no irradiance:
nothing to fix; a charge-power limit; the optimiser declining to charge, which
is the only software defect) and guessing between them is how an optimiser gets
tuned to solve a cloud problem. This card adds the channel. It does not do the
attribution.

AN HA ENTITY, NOT A REGISTER, AND THAT IS A PRODUCT DECISION. This add-on's
RS485 bus 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. `pv_entity` takes whatever `sensor.*` the site's
own PV integration provides, any brand HA can read.

POSITIVE IS PRODUCTION, AND THERE IS NO `pv_invert`. The convention is derived
rather than assumed: `meter_entity` is positive when IMPORTING and `batt_entity`
is positive when DISCHARGING (DOCS.md, Sources), both of which are "power
arriving at the house's AC bus", and production arrives there too. Those two
keys carry invert flags because they are BIPOLAR and are READ BY THE CONTROL
PATH - `inv.batt` feeds SAFETY-30's per-unit sign check and SAFETY-31's
circulating-power sensor, so a reversed sensor hands the site a plausible number
it acts on. Production is unipolar and is read by nothing: a reversed sensor
announces itself as -4 kW at noon in the very history this card creates, and a
flag would only let an installer hide it. No negative-value alarm either - a PV
inverter's own standby draw makes a small negative reading at night ordinary, so
any threshold would be a number nobody measured.

ABSENCE IS NEVER ZERO, AND "DROPPED" IS NOT ABSENT. `publish()` SKIPS a None,
which is right for `circulation` and exactly wrong here: a skipped row leaves
Home Assistant holding the last number forever and the recorder draws a FLAT
LINE through the outage, which is indistinguishable from a measurement and
manufactures the "there was no surplus" conclusion this card exists to TEST. So
the absence is published, with HA's own payload: `mqtt/const.py` declares
`PAYLOAD_NONE = "None"` and `mqtt/sensor.py` tests it BEFORE the numeric branch,
so the entity's state becomes `unknown` and the recorder stores a GAP. Read out
of home-assistant/core `dev` on 2026-09-24 and quoted at the constant.
`ABSENT_AS_UNKNOWN` is a one-key set and the suite asserts `circulation: None`
is STILL dropped.

THE UNIT IS READ OFF THE ENTITY. `mW`, `W`, `kW`, `MW`, `GW`, `TW` - HA's own
`UnitOfPower`, every factor an exact power of ten. A sensor with no unit, or a
unit outside that table, is REFUSED by name and the status page says which.
`read_inputs()`'s `abs(raw) < 50` kW-or-W guess is safe for a quarter-hour
demand forecast and is NOT safe here: 30 W of dusk is an ordinary reading and
that heuristic would publish it as 30 kW.

GENUINELY OPTIONAL, AND NOT A SECOND `price_now_entity`. validate.py does not
mention the key - it cannot conflict with anything, because nothing else reads
it. The MQTT row lives in a new `OPTIONAL_SENSORS` list whose `include` argument
DEFAULTS TO EMPTY, so every caller that has never heard of `pv_entity` -
test_mqtt.py's fixtures, tools/rehearse_roster.py, anything written next year -
announces exactly what it announced before. Unset: no state call at all, no
entity, no topic, no status row, no page row. Set and failing: a CAUTION
(`ok=False, warn=True`), never a `bad` row, so a telemetry channel can never put
a battery site into NOT READY.

IT MUST NOT BECOME A CONTROL INPUT, AND THAT IS GRADED TWICE. `test_pv.py`
part 6 drives 40 cycles of the real `cycle()` and asserts the commands are
bit-identical across unset / no reading / 0 W / 8 kW, with a COMPUTED census
(33 modules under app/) showing the material is mentioned in exactly three:
pv.py, main.py, mqtt.py. `tools/tel11_pv_trace.py` is the cross-tree half -
`safety56_behaviour_trace.py`'s pattern with a DIFFERENT control clause, because
this card's claim is that nothing differs rather than that only sentences do: it
REFUSES unless the two `app/` fingerprints differ and unless exactly one side
reacts to the option. Measured on 41 stimulus cells:

UNSET is byte-identical in BOTH documents, which is stronger than "the control
path is untouched": an install that does not set the option sees no change of
any kind, announcement and status rows included.

⚠️ AND THE CARD'S CENTRAL MUTATION WAS A SURVIVOR ON THE FIRST BATTERY.
`self.grid -= self.pv_w` in `read_inputs()` - +106 B, on disk, purged, genuinely
running - came back GREEN, because the fixture drove a 6 kW export over 12
cycles, which puts the loop AGAINST ITS RAIL: a command moving `slew_w` every
cycle produces the same ramp for -6000 W and for -14 000 W of apparent error.
MUTATION.md habit 23 with a saturated ACTUATOR in place of a coinciding value,
and it is in that file now as the habit's second instance. The fixture now
drives a 600 W import the loop SETTLES on, against a responsive meter, and asks
habit 23's own question as its own check: shift the METER by the same 8 kW and
confirm the commands really would have moved.

Evidence: 31/31 suites green in the CI image, checks.yml's exact command, purged
tree, `:ro`. Ten mutations, NO survivors, each on its own `cp -a` of the tree so
habit 18's revert hazard is closed by construction - table in
`DECISIONS/TEL-11-pv-production.md` §7 with byte deltas and sha256s.

⚠️ THIS IS A RUNTIME CHANGE BEHIND AN UNCHANGED VERSION, AND
`tools/predeploy_check.py` WILL REFUSE IT. `app/`, `config.yaml` and
`translations/` are all in its `RUNTIME` tuple and `config.yaml` still reads
0.10.1, so the gate reports a NO-OP deploy until a version is cut. That is PKG's
call and this card does not take it.

No CHANGELOG section: `test_version_gate.py` 11b refuses a newest `## ` heading
that is not config.yaml's `version:`, and opening one would mean taking that
same packaging decision. The operator account is in DOCS.md.

glenn schrooyenandClaude Opus 5 eb88646899 PKG-16: cut 0.10.1, so SAFETY-57's fix can reach an installed 0.10.0
checks / unit (pull_request) Successful in 8m0s
The Supervisor decides an update exists by comparing config.yaml's version
string with the one the box reports. master and release/1.0 both said 0.10.0,
so SAFETY-57 - a deadlock that parked the reference battery for ~13 min on
2026-09-21 while the house exported 2.4 kW - had no way of reaching the box
that has it. A patch bump is the delivery mechanism, not bookkeeping.

- config.yaml: 0.10.0 -> 0.10.1. Nothing else in the option surface moves:
  no key added or removed, no default changed, no enum widened, no rule added
  to validate.py, so a blob that starts on 0.10.0 starts on 0.10.1.

- CHANGELOG.md: a new `## 0.10.1` section, holding SAFETY-57's entry moved out
  of `## 0.10.0`. The entry opened by saying it was misfiled and that whoever
  cut the next version owned moving it; this is that cut, so that paragraph is
  replaced by what an operator actually needs in order to decide - what the
  deadlock does (command parked at 0 W, batt reading gated to MISSING, escape
  condition unreachable from inside the state), how to recognise it (setpoint
  stuck at exactly 0 W with the battery register flat, a STALE line and no
  clearing line) and that a restart of the add-on clears it.

- PKG-16 proper: `## 0.10.0`'s preamble still claimed 0.10.0 "has never been
  built or pulled anywhere" and that the reference install was on 0.7.0. Both
  stopped being true on 2026-09-20 ~22:18 CEST, when 0.10.0 was installed as a
  repository add-on (slug 68285ac7_goodwe_controller) and began regulating a
  real battery. The section's own bump argument was explicitly conditional on
  that; the condition has fired, so the argument is retold as history and the
  section is closed. This text is what the Supervisor shows beside Update.

Also fixes, in this file only, the three non-blocking documentation defects
raised on PR #104 - issuecomments 1445, 1446 and 1447:

- 1446: the live episode is 790 s, not 710 s. Re-derived rather than rescaled:
  at >= 790 s the committed 16-day replay gives 16 of 93, not 17.
- 1447: the BMS keep-alive pulse was an inference stated as a measurement. No
  committed capture identifies one, and on this episode 0x0518 never moved at
  all. The measured claim replaces the firmware story.
- 1445: "neither consumer can reach a verdict inside one window" is universal
  as written and graded on a fixture that puts the obligation back on every
  release. It now carries the qualifier the reviewer asked for, and names the
  unbounded case and why the shipped one-inverter roster cannot reach it.

The same three defects also sit in app/freshness.py, test_freshness.py,
DOCS.md and the DECISIONS note. They are deliberately NOT touched here: this
PR is config.yaml and CHANGELOG.md only, and none of them is worth delaying a
live safety fix. SAFETY-56 and SAFETY-58 are likewise untouched.

adminandClaude Opus 5 cb3f686555 PKG-14: cut 0.10.0, and say what an upgrade from 0.7.0 crosses
checks / unit (pull_request) Successful in 7m51s
`config.yaml` 0.9.0 -> 0.10.0, and the top `## Unreleased` block is closed
into `## 0.10.0` with a preamble that names the backward-incompatible
changes and who they reach.

MINOR, and NOT because eighteen tickets landed. A stored options blob the
previous version started on is REFUSED on this one:

  * TARIFF-07 retires three `price_provider` ids; a site set to one is
    refused BY NAME at startup. Measured on the reference blob, with a
    control on an accepted id so the refusals are about the ID.
  * TARIFF-18 moves `price_taxes_eur_kwh` 0.06 -> 0.11736. A site that
    STORED 0.06 is untouched, and - the non-obvious half - a taxes period
    table beside that stored 0.06 does NOT become a startup refusal on
    upgrade, because `SUPERSEDED_TAXES_DEFAULTS_EUR_KWH` reads it as
    untouched. Measured, with the counterfactual that the rung is not
    weakened (ORES's 0.1198 is still refused).
  * SAFETY-10 adds `shadow_mode`, shipped `auto`. An existing CONTROLLING
    install does not change by one watt and a FRESH one comes up observing.
    Measured cross-revision, 8f82dd4 -> e6da478, same stimulus through the
    shipped `Controller.cycle()`: byte-identical write streams, 13/13/25
    writes. Positive control: the same driver at `shadow_mode: on` gets 13
    writes to 5000 W on the older tree and one 0 W write on the newer.

And the one a reader of the newest section alone would miss: `ha addons
update` does not walk the versions, so a 0.7.0 install meets 0.8.0's and
0.9.0's rules at the same moment as 0.10.0's. Of those, SAFETY-39's rule 10
refuses 0.7.0's OWN shipped default `slew_w: 1000` against a 555.6 W
ceiling on a 5000 W rail. Measured red on this tree; the reference
install's `slew_w: 400` is measured green.

SCOPE, and it is drawn honestly rather than tidily. The top block's 18
entries all merged after the 0.9.0 bump `86bdf49`, so the block is closed
as-is and its `_this branch_` placeholders are resolved to merge shas.
⚠️ 0.10.0 SHIPS THREE MORE RUNTIME TICKETS THAT ARE NOT IN THAT TABLE -
SAFETY-43, TEST-21 and SAFETY-44 - and they are NAMED in the preamble
rather than moved, because re-filing this file's misplaced entries is
PKG-08. SAFETY-44 (`app/main.py`, `app/store.py`) is in the changelog
nowhere at all; that is said in both places. The second `## Unreleased`
block below `## 0.9.0` is ANNOTATED, not rewritten or emptied - UX-02 in it
shipped in 0.9.0, the other three in 0.10.0. No released section is
rewritten.

`test_version_gate.py` gains part 11: the bump and the closed section are
one act. PKG-09 refuses a deploy whose version did not move; nothing graded
the mirror failure, in which the version moves and the block is never
closed. Two sides from two files, a slicer with a synthetic positive
control run on every invocation, the retired ids read off `app/price.py` by
AST rather than transcribed, and the count of still-misfiled blocks frozen
so it can only shrink.

Mutations, all purged, tree bind-mounted :ro, backups at mktemp paths and
the revert fingerprinted:

  M1  `## 0.10.0` -> `## Unreleased`       +4 B    RED 2
  M2  version 0.10.0 -> 0.10.1             +0 B    RED 1   (ZERO-BYTE)
  M3  an id stripped from the NEWEST       +10 B   RED 1

  M5  `## 0.9.0` heading lost              -3 B    RED 1
  M6  a 2nd `## Unreleased` left standing  +27 B   RED 1

                                                   test_validate/test_price

⚠️ M5 WAS A SURVIVOR ON THE FIRST DRAFT. The slicer control was a sentinel
(`## 0.8.0`) that only a slicer running to EOF could reach, and deleting one
heading never gets there - ARCH-02's fifteenth instance, in a fresh costume.
11a now asserts the invariant instead: exactly one contents table per
section, which is what a lost heading breaks.

29/29 test files green. `tools/predeploy_check.py --deployed-version 0.7.0
--options <live blob>` CLEARED, exit 0, before and after.

Claude 8fa4febfef SAFETY-10: the whole decision path runs and nothing reaches the inverter
checks / unit (pull_request) Successful in 7m58s
Every optimiser defect this project has found was invisible from outside
while it was happening, and each was paid for at the meter first: SAFETY-45's
28 charge onsets an hour against a binding peak_cap_w, TARIFF-14's wrong
quarter-hour for 45 minutes in every 60, SAFETY-46's 598 Wh spent to gain
310 Wh. There was no way to watch what the optimiser WOULD do without letting
it do it.

`shadow_mode` runs strategies, arbiter, clamps and guards, records the
decision with its reason, and commands nothing.

⚠️ IT WRITES. It writes 0 W, on the ordinary heartbeat, through the ordinary
single writer. The inverter holds its last command forever - it has no meter
timeout - so "commands nothing" implemented as "stops writing" would leave
whatever was standing when shadow mode came on standing for as long as it was
left on, under a page saying nothing is being commanded. That is the failure
this repository keeps finding. Refreshing 0 W is also what
firmware/goodwe-master.yaml's 30 s stale-input watchdog requires of us; going
quiet would keep that board tripped for the whole run, which is an alarm being
used as a mode.

⚠️ IT IS NOT A SECOND WRITE PATH. No claim, no transport, no arithmetic of its
own. It is a substitution inside Controller._write_unit() - the single choke
point every write already reaches - in the same form as the three above it,
and it is the LAST of them, so SAFETY-28's gate and SAFETY-03's clamp still
grade the number the decision path produced.

⚠️ THE DEFAULT IS `auto`, NOT `true`, AND THAT IS THE CARD'S REAL CONTENT. The
Supervisor composes options as {**config.yaml defaults, **stored user
options}, so a new key with a new default reaches EVERY EXISTING INSTALL on
the next update - including the one regulating a real battery. A boolean
default-on would have stopped it silently. There is no mechanism by which one
key can default differently for a new install and an existing one, so
"default-on for new" is a value the add-on RESOLVES: `auto` is shadow while
control is STOPPED and live once it is STARTED. A fresh install ships
`auto_start: false` and comes up observing; an install that is controlling is
started and does not change by one watt.

THE FAILSAFES. Sign watchdogs (SAFETY-02/30): INERT - they grade
Inverter.standing_w(), which shadow mode holds at 0 W. Fed the shadow decision
they would disagree with a meter that never saw it and LATCH A TRIP THAT
SURVIVES INTO LIVE OPERATION AND A RESTART. Clamp (SAFETY-03), write gate
(SAFETY-28), meter freeze (SAFETY-18), peak guard: OBSERVE. Circulation
(SAFETY-31) and delivery (SAFETY-42): observe and may legitimately latch,
because their evidence is measured power. The operator stop is the one
deliberate change: enforced at the wire rather than as a P_SAFETY claim, which
would otherwise make every recorded decision read "stopped".

⚠️ RECORDED LIMITATION: _shadow_settle() re-seeds the carried command to what
stands on the wire, which makes the exit safe by construction - and therefore
the loop leg's shadow decision is ONE SLEW STEP, not a trajectory. A shadow
run answers "what would it command now", not "what would it have done next".
The strategies are unaffected; all three defects above are visible from one.

Graded on the writes and on the rendered surface, never on the flag: 22
mutations, no survivors, including one that lets a write escape and one that
goes silent instead of commanding 0 W. Closed loop on TEST-23 stage 3's rig,
same hour twice: live drives the pack to -2000 W and SoC 50.000 -> 62.331 %;
shadow commands 0 W throughout, SoC stays 50.0 exactly, and the arbitrage
decision is identical in action, instant, signed power, reason and arbiter
winner.

glenn schrooyenandClaude Opus 5 995da777ce TARIFF-16: the injection leg stops being one number
checks / unit (pull_request) Successful in 7m42s
`price.py` modelled what a site is PAID for export as ONE scalar. The market
publishes a line, and the cards say so in their own words: Eneco Zon & Wind
Dynamisch `0,1 x BELPEX-H - 1,188` c EUR/kWh - "het injectietarief is dynamisch
en kan per uur wijzigen", identical on the January and the September 2026 cards;
ENGIE Dynamic `(B x eSpot_15) - A`; Aspiravi `0,07 x Belpex - 2`.
`price_export_formula` carries that line with its OWN coefficients.

⚠️ THIS IS NOT A WRONG-TRADE FIX, AND SAYING SO IS PART OF SHIPPING IT.
`arbitrage.py` does not read `export_price_eur_kwh` at all - its own comment
says so, citing §9.3's near-zero Belgian injection price as the reason the
economically sound trade on this market is charge-cheap-to-displace-expensive-
IMPORT. Both hours it compares are all-in CONSUMPTION prices. No trade this
add-on takes today is decided by an injection price and nothing here changes
one. What it changes is what an operator is told, and what a future
export-aware strategy rests on: OPT-06 and any export logic would otherwise
inherit a scalar that cannot represent the market, and the 6% VAT asymmetry
would be invisible in the arithmetic. test_price.py 17h parses every module
under app/ and goes red the day something calls an injection reader, so that
sentence is graded rather than attested.

FOUR PROPERTIES A SCALAR CANNOT HOLD. Its own factor (Eneco 0,102 consumption
against 0,100 injection; Aspiravi 0,07 against ~0,10 - not the consumption B
with a sign flip). A negative offset, which `price_markup_eur_kwh: float(0,1)`
cannot express at all. VAT-exemption - "injectietarieven zijn vrijgesteld van
btw" - against 6% on consumption, representable only because `vat_pct` is PER
SPEC. And a price that goes below zero with no floor, under 11,88 EUR/MWh of
BELPEX-H, which is the middle of a sunny day.

⚠️ A NEGATIVE INJECTION PRICE IS ACCEPTED, AND THAT NEEDED A DIFFERENT BAND
RATHER THAN A LOWER FLOOR. `implausible_all_in()` floors the consumption leg at
+0.02 EUR/kWh of energy; applied to injection that refuses the real market in
the hours it matters most. Measured rather than argued: 17c puts ONE spec
through BOTH bands and prints that the consumption band refuses -0.03008
EUR/kWh while the injection band accepts it. The floor was not decoration - it
is what catches a card read a hundred times too small, the one unit error the
card self-check cannot see because it cancels out of a comparison between the
two sides - so the bound moves OFF the price and ONTO the coefficients, where
it is index-free and sign-free: a pass-through band (Eneco's injection leg is
1.00x, Aspiravi's 0.70x; the band is 0.10-10x) and an offset magnitude bound
(0.20 EUR/kWh against published 0.01188 and 0.02). Two rungs that can both
answer a hundredfold error, so each is graded on its REASON, each gets a
stimulus the other cannot reach with the precondition asserted as its own
check, and they are mutated TOGETHER (TEST-16).

⚠️ THE CARD SELF-CHECK APPLIES WHERE THERE IS A CARD, AND WHERE THERE IS NOT
THAT IS STATED RATHER THAN WORKED AROUND. `price_formula` can require a `card`
block because a Belgian card prints the consumption formula, the reference
index AND the resulting price. Eneco's INJECTION formula is printed with no
price beside it. Requiring a block would make the published line inexpressible;
inventing the estimate would grade the coefficients against arithmetic done
with the same coefficients. So the block is OPTIONAL on this leg and unchanged
on the other, the self-check runs at the same tolerance wherever a printed
estimate exists, and validate.py says at startup - "its coefficients are
UNGRADED" - when it does not, naming the two bounds that ran instead. This is
TARIFF-15 demonstrating two tariffs end to end rather than three, one card
later. 17e also MEASURES the size of that gap: a factor of 0.070 where the
contract says 0.100 - 30% of every export payment - passes both bounds, because
0.70x is a pass-through somebody really publishes.

ONE PARSER, NOT TWO. `parse_export_formula()` is `parse_price_formula()` with
its OPTION NAME as an argument - TARIFF-17's move on `parse_static_profile()`,
exactly - and everything that differs between the legs is a string in one
`_LEGS` table. A second copy would be a second unit table, a second NaN rule, a
second unknown-key rule and a second `to_resolution()`, diverging first on the
23- and 25-hour days. test_price.py 17b pins it two ways: all 32 grammar names
are defined in exactly ONE module under app/, with the scope COMPUTED by
parsing every file rather than listed; and twelve refusal sentences for the new
option are DERIVED from the old option's own sentence rather than transcribed.
The four sentences that deliberately differ are named, with what differs, and
asserted to differ.

NOTHING CHANGES FOR A SITE THAT DOES NOT SET IT. The option ships "";
`export_price_eur_kwh()`'s body is byte-identical, pinned on the AST rather
than on the source text; `export_price_at()` falls through to it for every
index value. 17f compares seven option dicts x five index values against the
pre-TARIFF-16 expression with `==`.

`price_export_formula` joins FRAMEWORK_KEYS, BANNED_IN_PLUGIN_CODE is derived
from that set, and `code_leaks()` refuses a plugin that names it with nothing
else edited.

ALSO CORRECTED HERE: config.yaml's comment beside `export_price_eur_kwh` still
read "no shipped supplier publishes a dynamic injection curve". TARIFF-07
struck that claim from app/price.py and DOCS.md and did not reach config.yaml,
where it has been shipping since.

20 mutations, every one red on a named check, ledger in test_price.py below
section 17 - including a ZERO-byte one (the two legs transposed in the
VAT-asymmetry banner: no decision moves, only the sentence) and a ONE-byte one
(`card_required=True` on the injection leg). Three run over all 29 files and
red on test_price.py alone. 29/29 green.

glenn schrooyenandClaude Opus 5 9c65ac2cf8 TARIFF-18: price_taxes_eur_kwh stops shipping at half the real figure
checks / unit (pull_request) Successful in 7m48s
`price_taxes_eur_kwh` shipped at 0.06 EUR/kWh with no recorded provenance -
no card, no date, no component list - and roughly HALF the true Flemish
all-in non-energy figure. It now ships at 0.11736, and the rows it is made
of are in the code rather than in this message:

  Fluvius distribution (Antwerpen)              5,35   c EUR/kWh
  Bijzondere accijns, "Alle verbruik"           4,876
  Bijdrage groene stroom en WKK Vlaanderen      1,51
  Energiebijdrage (0 EUR/MWh since 2026-08-01)  0
                                               ------
                                               11,736 c EUR/kWh = 0.11736

Eneco residential card for Flanders, September 2026, incl. 6 % VAT.
`app/price.py`'s FLEMISH_TAXES_COMPONENTS_EUR_KWH carries the rows and
test_price.py section 1b re-adds them - and also compares the total against
the card's own figures typed in the test file, so an edit that moved the
rows and the default together is still caught.

WHAT THIS IS NOT. It is not an arbitrage-correctness fix and it cannot be.
This scalar is a LEVEL component: an additive constant cancels exactly in
`max - min` and leaves the argmin where it was. TARIFF-17 shipped that proof
and it is unchanged - test_price.py 16b drives six flat scalars spanning and
exceeding the whole per-DSO range and gets the identical cheapest hour and
the identical spread to the last digit. DOCS and the CHANGELOG say so in
those words.

WHAT IT IS. A display and guard fix:

  * every number an operator reads, which at half the true value made the
    add-on look considerably better than it is; and
  * §17's negative-price guard in arbitrage.py - the one rung that tests an
    ABSOLUTE all-in price rather than a difference. It fires when
    `spot < -(markup + taxes)`, so its boundary moves -0.09 -> -0.14736
    EUR/kWh of spot. test_arbitrage.py section 2c drives both sides through
    the shipped decide() and pins the boundary from below as well.

The default is Antwerpen's real row, near the LOW end of the 0.117-0.131
per-DSO band, and that is deliberate: the error directions are not
symmetric. Too high carries a genuinely negative hour above zero and the
add-on exports into paid-for disposal - §17's own case. Too low only
declines a discharge that would have paid.

TARIFF-17's INTERACTION, WHICH HAD TO BE DECIDED. Nothing in that rung
hardcoded 0.06; it read PRICE_OPTION_DEFAULTS, so moving the default moves
what it refuses. The Supervisor sets `App.options = deepmerge(config.yaml
defaults, stored options)`, so a saved blob carries the key whether it was
typed or not - every stored 0.06 became "non-default" with nobody editing
anything, and a working Walloon or Brussels site with a taxes table would
have met SystemExit(78) on the upgrade over an inert number. price.py now
carries SUPERSEDED_TAXES_DEFAULTS_EUR_KWH = (0.06,) and validate.py reads a
superseded default as untouched too. The rung is NOT weakened: 0.1198 beside
a table is still refused by name, and the refusal now names both figures.

config.yaml and PRICE_OPTION_DEFAULTS moved together; CFG-03's tripwire
(test_price.py section 1, test_defaults_pin.py) stayed green by agreeing.
test_price.py section 0's fourth check was REWRITTEN rather than re-pointed:
it used to justify the file's own grading constants by observing that the
shipped pair was degenerate (0.06 is exactly twice 0.03). TARIFF-18 ends
that coincidence, so the sentence is no longer true and is not kept.

29/29 test files green. Mutation ledger on the PR.

scalar. This adds `price_taxes_profile`, which carries the TAXES component as
a period table, and makes `assemble()` evaluate it at each point's own instant.

⚠️ THE FLAT SCALAR WAS NOT A WRONG NUMBER, AND THIS IS NOT A CORRECTION OF ONE.
The optimiser reads exactly two quantities off a series - the spread
`max - min` over the firm points, and which hour is cheapest - and an additive
constant identical in every hour cancels out of the first and leaves the second
where it was. It is provably inert. Measured, and printed by test_price.py 16b
on every run: with a flat taxes figure of 0.00, 0.0739, 0.1198, 0.1327 or 1.00
EUR/kWh the same 24-hour feed is cheapest at 13:00 in all five cases and its
spread is 0.1500 EUR/kWh in all five cases. What was missing is anywhere for an
HOUR-VARYING non-energy component to live. This is a missing capability, not a
bad constant.

Belgium has one. Fluvius distribution is a single rate - its tariff-card row
reads `Normaal | Uitsl. nacht`, where exclusive night is a separate physical
circuit and not a night register - so nothing changes for the reference site in
Flanders. The Walloon DSOs and Sibelga are on the same card with four columns,
`Enkelvoudig | Dag | Nacht | Uitsl. nacht`, and the gap is real money (c/kWh):
ORES 13,27 / 7,39; AIESH 15,17 / 8,21; Tecteo RESA 12,20 / 7,01; Sibelga
9,39 / 7,10; ORES IMPACT 2026 16,578 / 5,090.

⚠️ AND THE BANDS ARE ANTI-CORRELATED WITH WHAT THE BATTERY WANTS TO DO. The
cheap network hours are the cheap spot hours, so flattening them does not shift
the curve - it UNDERSTATES the spread and declines cycles that would have paid.
Same feed, same markup, the only difference being the taxes argument:

    flat 0.0000 / 0.0739 / 0.1198 / 0.1327 / 1.0000
                                       -> cheapest hour 13, spread 0.1500
    ORES dag 0.1327 / nacht 0.0739     -> cheapest hour 03, spread 0.1788

The regression check grades WHICH HOUR IS CHEAPEST, not the spread: an
implementation that reads the table once and adds one number to every point is
the LEVEL bucket wearing a period table - right magnitude, wrong shape - and a
spread assertion passes on it. Measured: hoisting the lookup out of
`assemble()`'s loop (+17 B) is red on six named checks in test_price.py and
GREEN in the other 28 files.

ONE GRAMMAR, NOT TWO. `static_tariff.py` already shipped the periods, the day
selectors, the tiling rule and the DST handling, so `parse_taxes_profile()` is
the same parser with the option name and the "what this number means" clause as
arguments. A second tiling rule would be a second set of 23- and 25-hour-day
bugs. test_static_tariff.py section 10 pins that two ways: by parsing every
module under `app/` and asserting the grammar is defined in exactly one of
them, and by deriving each of thirteen refusal sentences for the new option
from the old option's own sentence rather than transcribing them.

`Component.TAXES` semantics, `code_leaks()` and the double-counting guarantee
are untouched. The new key joins FRAMEWORK_KEYS, BANNED_IN_PLUGIN_CODE is
derived from that set, and a plugin that names it is refused at `register()`.
It reaches both plugins that take taxes - `custom_formula` ({ENERGY, MARKUP})
and `generic_dayahead` ({ENERGY}) - and not `manual_csv`, which is all-in: the
table is routed through `capabilities().adds`, exactly as the scalar is.

⚠️ A MALFORMED TABLE IS REFUSED AT STARTUP, NOT AT THE NEXT FETCH. It is read
on the ~30 s planning path, and a table that first fails at 03:00 is a site
that stops pricing at 03:00, which §11.4 turns into a quiet fallback
indistinguishable from a healthy fixed-tariff day. validate.py refuses three
things: a table that does not tile the day; a table set beside a NON-DEFAULT
`price_taxes_eur_kwh`, because the table wins and the scalar would then be a
number the operator typed that decides nothing; and a whole card typed in
CENTS, which is how these figures are printed. That last rung is not a
restatement of the parser's +-10 EUR/kWh bound - ORES's 13,27 trips the parser,
but Sibelga's entire card, 9,39 and 7,10, is under it and would otherwise have
started as a 9.39 EUR/kWh levy. Both rungs are graded by the REASON each gives,
and mutating them together (TEST-16) moves three rows.

NOTHING CHANGES FOR A SITE THAT DOES NOT SET IT. The option ships "", and the
scalar path is unchanged arithmetically rather than merely in intent:
test_price.py 16f reproduces the pre-TARIFF-17 expression and compares 12
capability/scalar combinations point for point with `==`.

13 mutations, every one red on a named check, ledger in test_price.py below
section 16k with byte deltas and the one equivalent mutant named. 29/29 green.

Claude Opus 5 ac9854886b TARIFF-15: your own tariff card, as two coefficients the card itself grades
checks / unit (pull_request) Successful in 7m14s
A Belgian dynamic contract prices energy as `B x index + A`, and the two
coefficients exist on exactly one artefact: the customer's own tariff card.
There is no machine-readable source for them anywhere - CREG's consumer
tariff-card pages 404, CREG Scan is a JS wizard, the annual report has the
supplier list without per-product coefficients, VREG was unreachable, and
every coefficient found in research came off a supplier's own PDF, one
image-only. So nothing can be scraped and a per-supplier plugin would have no
source for its numbers, which is why TARIFF-07 withdrew three of them. The
customer is the only party who can see their own coefficients; they type them.

New provider `custom_formula`, one new option `price_formula` (a JSON string,
the `static_profile` precedent exactly), and a new module
`app/custom_formula.py`. The index path is `generic_dayahead`'s, not a second
one: the URL/override decision is now one shared `dayahead_feed_url()` both
plugins call, same feed, same Brussels-calendar range, same columnar parser,
same declared egress hosts.

It declares {ENERGY, MARKUP}, NOT ALL_IN. A card's Tariefformule line is the
energy component alone - Eneco tabulates network tariffs and levies
separately, ENGIE states the formula excludes network, distribution,
transport, levies and excise - so ALL_IN would lie for every operator who
typed what their card says and would drop the taxes from every hour
(0.2125 -> 0.1555 EUR/kWh, measured).

THE CARD IS THE GRADER, and that is why this is safe to ship. The framework
already mechanises that a PLUGIN cannot double-count. This introduces a risk
none of those guards can see because it is config, not code: the OPERATOR
double-counting, by folding network charges into `offset` while
price_taxes_eur_kwh carries them too. So validate.py recomputes the card's own
printed price from the operator's coefficients at startup and refuses to start
unless the two agree to within 0.01, naming the discrepancy. An inflated
offset cannot pass: 15.55 becomes 28.27. The same check catches VAT omitted,
VAT doubled, a transposed digit and a unit mismatch between the two sides.

And the limit, in the same sentence as the claim: it grades the coefficients
against the card, NOT the card against reality. A consistent-but-wrong pair
passes. A second refusal covers the one unit error the first cannot see - the
one applied to both sides at once - by bounding the card's own point to
0.02-1.00 EUR/kWh. Its FLOOR is applied to the energy figure rather than the
all-in one because the shipped 0.06 of taxes is three times that floor and
would carry a hundredfold error over it alone; found by writing the mutation,
not by review (M10, +0 B).

The market's own arithmetic, reproduced through the shipped code:

  Eneco (0.102 x 133.9905 + 1) x 1.06 = 15.5471   card prints 15,55
  ENGIE (0.1   x  61.96   + 0.9) x 1.06 = 7.5218  card prints 7,522

NO EXPRESSION EVALUATION OF ANY KIND. The string is settable over HTTP through
the add-on's own ingress page, so eval on it is RCE in a root container
holding SUPERVISOR_TOKEN and driving an inverter over RS485 - but the deciding
argument is that an expression is UNVERIFIABLE: two coefficients can be graded
against the card, an arbitrary expression cannot be graded against anything,
so it would make the invisible-wrong-coefficient problem strictly worse. An
unknown field is REFUSED rather than ignored, so `"expr"` is told it does not
exist. Future shapes become named fields, never a grammar. test_price.py 15f
walks the module's AST for eval/exec/compile/__import__/literal_eval and
exercises the scanner's red direction on every run.

Refused at startup: card absent or out by >0.01; `units` absent (no default);
factor == 0 (every spread 0, arbitrage silently never fires - the message
points at static_profile); factor < 0 (inverts the market); vat_pct outside
0-30 (0 stays legitimate); non-finite or non-numeric; unknown field, index or
resolution; the plausibility band. A card older than ~6 months WARNS and does
not refuse - ENGIE freezes coefficients for a contract's duration. Negative
output prices are not refused anywhere.

A startup preview logs the next 24 h as `index EUR/MWh -> all-in EUR/kWh` with
min/median/max and the day's spread, through a new default-silent
`PriceProvider.startup_preview()` hook - only the plugin knows what went in to
its own arithmetic. Emitted once per process, and a preview that raises cannot
cost the site its prices.

`custom_formula` joins the config.yaml enum through the DERIVED set
PROVIDERS | RETIRED_PROVIDERS | {"off"}, not a hardcoded list. Both
translations describe the option and the new id. DOCS.md replaces the
"planned" sentence with the shape, a worked example from a real card, a real
startup transcript and the limit of the check stated beside the claim.

22 mutations, one per check added, no survivors - MUTATION.md carries the
ledger. M13 (the preview's index column) was a -13 B survivor of the whole
suite on the first attempt because the check graded the HEADING and not the
row; it is graded on a rendered row now. All 29 suites green.

adminandClaude Opus 5 f620f7cf80 TARIFF-07: three plugins that never fetched a price are withdrawn, and a site configured on one is told so
checks / unit (pull_request) Successful in 7m12s
engie_dynamic, totalenergies_dynamic and eneco_eddy are removed from PROVIDERS
and from every surface that listed them. They did not stop working - they never
worked. Re-verified by hand on 2026-09-13 before deleting anything: 404 with
Kong's "no Route matched with those values"; a TLS handshake that fails because
api.totalenergies.be is absent from the certificate's SAN list; 404 with an
empty body. All three are also structurally impossible - the coefficients are
per-contract and behind a customer login, there is no regulator index, and
"Eddy" is not an Eneco product at all.

⚠️ BACKWARD-INCOMPATIBLE. A config legal on the current version is refused on
the next. That is the point of the change: §11.4 turned every failed fetch into
a silent fall back, so a site on one of these ids has been running on
static_profile - or on nothing - since the day it was set, with nothing on its
status page ever differing from a working provider that never found a cheap
hour. validate.py now refuses a retired id with a message naming the id, the
endpoint, what that endpoint answers, which tariff has really been in force,
and what to set instead. No version number is picked here; that depends on a
fact about the live box.

⚠️ config.yaml's price_provider enum deliberately KEEPS all three ids. The
Supervisor validates the options file against that enum before the add-on
starts, so removing them would make an existing config schema-invalid and the
refusal above would never be reached on exactly the sites that need it.
PROVIDERS is two; the enum stays six; test_price.py asserts the schema offers
exactly PROVIDERS | RETIRED_PROVIDERS | {"off"}, derived rather than typed, and
register() refuses to re-register a retired id.

PriceProduct.REALTIME, _WIDE, Uncertainty.REALTIME_PRODUCT and WIDEN_FACTOR's
2.5 are KEPT with no shipped declarer - it is the AC2 seam, and a reviewer
finding a mechanism with zero callers would reasonably delete it. Recorded in
DECISIONS/TARIFF-07-withdrawing-three-plugins.md and pinned by a check.

False claims corrected: every "Belgian imbalance product" claim about
eneco_eddy (DOCS.md, price_forecast.py, price_history.py, static_tariff.py,
FCST-04, CHANGELOG - the two released entries annotated in place rather than
rewritten); the quarter-hourly examples now cite Belgian day-ahead, which
really does settle per quarter since the 15-minute MTU; and
export_price_eur_kwh's "no shipped supplier publishes a dynamic injection
curve", which is false - Eneco publishes 0,1 x BELPEX-H - 1,188 and ENGIE
(B x eSpot_15) - A, same two-coefficient shape with its own coefficients and
its own VAT treatment, so the scalar is a simplification and not the market.

DOCS.md's provider table is two rows and now says honestly what a Belgian
dynamic customer should do today, including that generic_dayahead cannot
express B x spot + A and that price_markup_eur_kwh: float(0,1) could not hold a
negative offset. The formula provider is referenced as planned, not built.

_points_from_json() went with the plugins it served: it read a shape no feed
anybody here has ever reached publishes. The one place it survives is a
negative stimulus, named row_shape_body().

Nine mutations driven, all red; table in the decision record. 29/29 suites
green.

adminandClaude Opus 5 e6c45a61e7 TARIFF-10: configuring a price provider is what fetches prices
checks / unit (pull_request) Successful in 7m19s
amain() started the background tariff refresh only when arbitrage_enabled was
on, and that option ships false. run_tariff_refresh is the only caller of
resolve_tariff(), which is the only caller of price_history.carry() - so on a
shipped install with a price provider configured nothing was ever fetched: no
plan resolved, /data/price_history.json never created, the Price history status
row reading `empty` for the life of the install, and TARIFF-09's short-horizon
warning unable to fire because there was no fetch to warn about. Measured over
a 40 h two-instance soak on one feed: 0 requests and `present: false` across all
802 samples, against a resolved 132-point plan on the instance with arbitrage
armed.

git log -S puts the refresh task, its arbitrage.enabled() guard AND the DOCS.md
sentence saying a configured provider still fetches in the same commit - OPT-04,
bdd7f18; config.yaml has carried the claim since TARIFF-02, 852fc7c. The prose
and the code disagreed from the moment both existed and nothing compared them.
config.yaml and both translations additionally carried a claim that had rotted
the other way - "nothing consumes the price series yet", untrue since OPT-04
shipped the consumer. All four surfaces now say what the add-on does, and a
check pairs DOCS against the DRIVEN behaviour so they cannot drift again.

The gate is tariff_refresh_wanted() = provider_configured(opts) or
arbitrage.enabled(opts), and the `or` is a STRICT WIDENING: every configuration
that started the task before still starts it. The second term is not there for
symmetry. price_provider: off + a static_profile + arbitrage_enabled: true is a
configuration validate.py explicitly ACCEPTS and it trades - measured, at
cycle_cost_threshold_eur 0.05 on a 0.20/0.284 day/night profile,
ARBITRAGE_CHARGE -5000 W. Gating on the provider alone would leave that site's
tariff_plan at None forever and answer "no tariff plan has been resolved yet" on
every cycle, silently disarming a strategy the UI says is running.

Nothing acquires a periodic HTTPS call. With price_provider off, resolve_tariff()
answers out of the static profile without opening a socket (driven and counted:
0 requests), and the true shipped default - no provider, no trading - starts no
task at all. What decides whether a request leaves the machine is price_provider
and only that. The literal reading of the ticket's AC2 - drop the `or` - is one
token and is recorded in DECISIONS §3 with what it costs, for the owner.

AND NOTHING TRADES THAT DID NOT TRADE BEFORE. cycle()'s
`if arbitrage.enabled(self.o):` is untouched, and that is graded directly rather
than inferred from the gate having moved: Controller.cycle() is driven on a
resolved provider plan with the peak guard asserted clear, and arbitrage_enabled
is the only option that moves between the rows - false/false give +180 W
("loop -> 180 W") on both the cheap-now and dear-now plans, true/true give
-5000 W and +5000 W ("arbitrage -> ...").

TariffPlan.cheap_now() is deliberately NOT wired, decided rather than inherited
(DECISIONS §4). A provider-backed plan now exists on every configured site, so
Cheap window could read it - and Cheap window feeds the maintenance cycle's grid
top-up, the one place a price moves energy without trading being armed. On a
provider-only site static_status() returns False on every cycle, so adopting it
would take a paid grid top-up from never to sometimes. self.cheap stays on
static_status(); what adoption would take is listed rather than left implied.

THE CHECK THAT WOULD HAVE CAUGHT THIS is test_price.py section 13, and it grades
REACHABILITY FROM A CONFIGURATION rather than the shape of an `if` - the `if` was
exactly what somebody meant to write. amain()'s guards are EVALUATED against real
option dicts, whatever they are spelled as; the call graph under app/ is walked
to see whether the tasks those guards start arrive at resolve_tariff(), wherever
it has moved to; and then the fetch is DRIVEN with a counting transport, because
a graph is an argument and a counted request is an observation. What the
instrument cannot see is printed on every run, largest hole first.

Evidence: 29/29 green. 13 mutations in 14 runs - M10 re-run as M10b once it was
closed - each applied to a fresh cp -a of the clean worktree rather than
reverted (MUTATION.md habit 18), purged, :ro, -B. The
shipped defect - the gate back at arbitrage.enabled(opts), -4 B - is red on
seven named checks. Dropping the `or` (-27 B) is red on the strict-widening row;
removing cycle()'s trading gate (+8 B) is red on both AC3 rows. The instrument
is mutated too (habit 16): _reaches() always True and _task_sites() returning []
are both +0 B and both red.

Two findings are recorded rather than rounded off. provider_id() dropping
.strip() (-8 B) was a real SURVIVOR across four price suites - nothing fed a
padded provider id - and is closed in this commit by the padded-id pair; and the
first draft of the AC3 fixture fed five minutes of P1 telegrams, so whether the
peak guard was blind depended on where the wall clock sat inside the billing
quarter and the armed baseline failed to trade on some runs. It is 900 s now,
and the guard's clear state is a check rather than an assumption.

Claude Opus 5 17b7b447c4 TARIFF-09: ask the day-ahead feed for the horizon it was handed
checks / unit (pull_request) Successful in 7m10s
`generic_dayahead.fetch()` accepted `since` and `until` and requested the
bare `?bzn=BE`, which answers ONE Brussels day. Everything past today was
then filled from yesterday's profile by FCST-04, flagged provisional, and
§8.3 drops provisional hours from the trade set -- so the optimiser never
saw tomorrow as firm, at any hour of any day, and nothing reported it.

Measured on 4257e38 at 2026-09-10T09:00+02:00, 48 h horizon, live feed,
yesterday seeded through the shipped read path:

    60 firm points (15 whole hours) + 33 carried hours of 48 requested
    carried: 24 h on 2026-09-11, 9 h on 2026-09-12
    arbitrage(0.10): buy 11:45 and sell 19:45 -- BOTH on 2026-09-10
    firm local days = [2026-09-10]

The ceiling was structural: with a one-day window, at hour H a 48 h horizon
is at most 24-H firm and 24+H carried. At 23:00 that is 1 and 47, and the
remaining firm spread (0.0464 EUR/kWh) no longer clears the default 0.10
threshold, so arbitrage is refused outright. FCST-04's fill covers the
window until the ~13:00-14:00 CET auction; it was never meant to cover
every hour of every day.

The data exists and the endpoint serves it: verified 2026-09-10T07:45:49Z,
`?bzn=BE&start=2026-09-09&end=2026-09-10` returns 192 quarter-hours across
two local days. Committed unmodified beside TARIFF-08's captures, with the
URL, retrieval time and sha256 recorded and RE-DERIVED by the replay.

THE RANGE IS DERIVED ON THE BRUSSELS CALENDAR, not the UTC one. 22:30 UTC
in summer is already tomorrow in Belgium, so a UTC-derived start asks for
the day the controller has just left and drops the day it is standing in,
for the last one or two hours of every day. That is `_bdate()`'s lesson one
layer up with a worse consequence: `_bdate()` misfiles an hour, this never
fetches it. `until` is exclusive, so local midnight belongs to the day
before it; an inverted window collapses to one day rather than a backwards
range. Both ends are graded and both are driven red by mutation.

After, same code path and window, a feed serving both days: 39 firm hours
and 9 carried (was 15 and 33), firm across TWO Brussels days, and the
permitted cycle buys on one day and sells on the next.

`price_feed_url` IS THE EXACT URL AND THE PLUGIN APPENDS NOTHING. `start`/
`end` are this feed's spelling and the provider declares a second host
whose parameters are different, so merging would produce a request nobody
typed and the short horizon anyway. The cost is real, so it is not silent:
a WARNING on the shipped logger at fetch time names the consequence and the
start..end that would otherwise have been asked for. `dated_feed_url()`
refuses to append to a base that already carries a query string, so the
blind-append shape cannot come back by edit.
DECISIONS/TARIFF-09-the-range-and-the-override.md argues the alternative.

Before publication nothing regresses and it is graded, not assumed: at
09:46 CEST the two-day request came back byte-identical to the one-day
body, and that stays a `series` of what exists with FCST-04 filling the
rest. A `no_data` there would switch a working site's arbitrage off every
morning -- the mutation that adds that rule is red by name.

The plugin contract is still NOT enforced: three shipped plugins point at
endpoints nobody has verified, and a rule obliging them to pass a range
would be satisfied by an invented parameter name -- TARIFF-08's defect
moved from the response to the request. Which plugins consume the range is
pinned as a literal instead.

11 mutations, all red, no survivors; each applied to a fresh copy of the
tree rather than reverted, through tools/mutation_run.sh. One is +0 B (a
single price digit inside the committed capture) and the re-derived sha256
catches it. MUTATION.md habit 20 records why a fixture could never have
reached this: a captured body is the answer to a URL, and no property of a
body says which URL was asked for. All 29 suites green.

Claude Opus 5 2271e147c6 SAFETY-43: delinquency measured against the ask, not against a flat 500 W
checks / unit (pull_request) Successful in 6m20s
`delivery.delinquent()` named a unit whose `short_by()` gap exceeded an
ABSOLUTE `min_w = Tuning.saturation_w = 500 W`. OPT-09's SoC-aware weights
shrink a low-headroom unit's share, and shrinking the share shrinks the gap, so
a unit standing at +125 W and delivering 0 W - 100 % delinquent - was never
named. Measured end to end on the real loop (test_packshare.py part 8b):

    load 1500 W, B wedged at 15 %, equal weights    named on 199/200 cycles
    load 1500 W, B wedged at 15 %, OPT-09 weights   named on   0/200 cycles

⚠️ The suppressed regime is the quiet one: at a load the healthy sibling covers,
the meter is satisfied, `unmet_w` is 0 and no action-log line fires, so this
alarm is the ONLY instrument that would have told the operator.

WHAT CHANGED, in one line:

    named if  short_by() > min_w  OR  short_by() > frac * share

⚠️ `min_w` WAS NOT LOWERED. It exists to stop normal saturation being reported
as delinquency, and lowering it trades a missed alarm for a false one on every
unit at once - SAFETY-41's four-attempt regime. This is a SECOND way to be
named, not a looser first one: all seven of test_delivery.py part 1's existing
fixtures answer identically under both rules, and the absolute arm's suppression
window is still exactly 1000 W / 6500 W, still asserted in part 8b.

THE FRACTION IS DERIVED, 0.85. admin/goodwe:sim/delivery_window.py gained a
`--fractions` axis and grades the constant over the SAME 2640 no-fault runs that
produced `delivery_hold_s`'s 35.0 s floor. Worst continuous legitimate episode,
worst of three families, twenty fractions:

    frac   0.05  0.10  0.15  0.20  0.25  0.30  0.35  0.40  0.45  0.50
    worst  90.0  90.0  70.0  70.0  60.0  55.0  55.0  60.0  45.0  45.0  s
    frac   0.55  0.60  0.65  0.70  0.75  0.80 *0.85  0.90  0.95  0.99
    worst  40.0  40.0  45.0  45.0  45.0  45.0  40.0  40.0  40.0  40.0  s
    absolute arm alone: 35.0 s (SAFETY-42 §3.3, reproduced in the same runs)

⚠️ NO CLIFF ANYWHERE: 0.45-0.99 is flat within one control cycle, and it is not
monotone - §3.3's own mechanism (c). ⚠️ "Zero false namings" is NOT achievable
at any fraction and the record says so; what is zero is false ALARMS - 90.0 s
worst against a 185 s hold, so nothing comes within 95 s of notifying anybody.
N=1 control 0.0 s at every fraction in all 2640 one-inverter runs; flapping
0.0 s in all 840.

DRIVEN. Part 8b pinned the SUPPRESSED behaviour and said "if it ever goes red
because the alarm fired, read the card that made it fire". It now grades BOTH
rules on one run - `share_frac=None` is SAFETY-42's rule exactly:

    OPT-09 weights, absolute arm alone   named on   0/200
    OPT-09 weights, the shipped rule     named on 200/200

POSITIVE CONTROL. Same fixture, same weights, same 125 W share, one legitimate
fact changed: a pack at its own 10 % cut-out is named on 0/200 (account() still
gates it), and a unit delivering HALF its share is named on 0/200.

N=1 BYTE-IDENTICAL, asserted: `plan()` handed a `weights` mapping that raises on
any read still answers identically at a roster of one, and the same mapping
raises at a roster of two; `delinquent()` answers {} on all 84 single-unit
(share, measured, rule) combinations including 0 of 125 W.

MUTATION, run on fresh :ro trees: M12 (drop the relative arm), M13 (frac -> 1.0)
and M14 (frac -> 0.05) are all red on named checks. The constant cannot move in
either direction unseen.

⚠️ CFG-07 gets ONE CONTROL CYCLE WORSE and is deliberately not fixed here: the
worst legitimate episode goes 35.0 -> 40.0 s, so the schema's `int(30,900)`
false-tripping band widens from [30,35] to [30,40]. CFG-07 should be re-derived
against 40.0 s.

No option value, no schema bound and no default changed. 27/27 suites green.

adminandClaude Opus 5 57775d4e06 TEST-21: delivery_hold_s's floor re-derived, and 30.0 s did not reproduce
No code and no option changes. What changes is a number this repository claimed
about a shipped safety constant.

`delivery_hold_s: 185` shipped resting on "30.0 s, the worst continuous
legitimate episode at the shipped threshold across all 2640 runs", plus a lag
sweep giving 45.0 s and 90.0 s - from a harness `DECISIONS/SAFETY-42` §1
deliberately did NOT commit, because it imports `plantsim` and `frame_check` out
of admin/goodwe. So the floor under a safety constant could not be re-run. That
is PROC-01's shape, with eleven instances in three days.

The harness is committed now, in admin/goodwe as `sim/delivery_window.py`, and
NOT here. `plantsim` and `frame_check` are that repo's; restating them in this
tree is CI-08's coupling, which has broken three times, and the alternative
fate - skipped for want of its imports - is a green that establishes nothing.
There the dependency runs one way: THIS repo's `control`, `arbiter` and the
shipped `delivery.delinquent()` are imported live out of whichever checkout is
under test. Its `--selftest` is now a step in that repo's `checks.yml`, so a
change here that moves `saturation_w`, `max_w`, `delivery_hold_s` or the shape
of `delinquent()` goes red there instead of leaving a stale number here.

    cd goodwe/sim && GOODWE_ADDON_REPO=/path/to/goodwe-addon \
        python3 -B delivery_window.py --selftest --campaign --blag

⚠️ THE HEADLINE DID NOT REPRODUCE: 35.0 s, not 30.0 s. Recorded as measured. The
harness was not adjusted until it agreed - the one correction made during the
rebuild was made AGAINST the doc's number (§1 records it) and made every figure
LARGER.

WHAT REPRODUCED - and it is the part the compatibility promise rests on:
  * the N=1 control arm is 0.0 s at EVERY threshold in EVERY run. §3.2's algebra
    measured, not argued.
  * the flapping family is 0.0 s everywhere in all 840 runs - the family that
    defeated SAFETY-30's site window still cannot touch this check.
  * 45.0 s at twice A's lag, to the cycle.

WHAT DID NOT:
  * the headline, by one control cycle (30.0 -> 35.0 s); the reversal family by
    two (20.0 -> 30.0 s).
  * the NON-MONOTONE curve. §3.3 finding 3 read 55.0 s at 250 W against 40.0 s
    at 100 W as a property of the reduction. This rebuild's curve is monotone.
    The mechanism is real and is still the reason not to read either table as a
    sensitivity curve, but it is an ARGUMENT now, not a measurement, and it is
    written down as weaker.
  * the low-threshold rows, badly (40.0 -> 120.0 s at 100 W). Nothing ships
    there, but that gap is the honest measure of how much of the original table
    was a property of axes nobody wrote down. §3.3 fixes every axis COUNT and
    RANGE and no individual value; the rebuild prints its choices above its own
    table so the caveat travels with the number.
  * the four-times-slower row moved the OTHER way: 75.0 s, not 90.0 s.

185 s IS NOT CHANGED. It is 5.29x the re-measured worst (the record claimed
6.2x), 2.47x the four-times-slower case, 6.2x the firmware's LINK_STALE_S veto
and 4.9x inside the billing quarter. All four bounds clear and none narrowly,
and the ordering of the argument is unchanged. Moving a shipped safety constant
because a margin went from 6.2x to 5.3x while every bound holds would re-open
SAFETY-41's four-attempt false-trip regime for nothing.

⚠️ ONE CONSEQUENCE AN OPERATOR CAN HIT. At 30.0 s the rig's floor coincided with
the firmware's veto and a reader could not tell which was binding. At 35.0 s the
rig's is strictly the binding one - and it is ABOVE the schema's own
`int(30,900)` minimum. `delivery_hold_s: 30` is therefore below a MEASURED
legitimate episode and would report on ordinary saturation. Both translations
now say so. Raising the schema floor is a change to a shipped option's contract
and is left to its own card rather than smuggled in here.

⚠️ THE B-LAG ROWS ARE RELABELLED THROUGHOUT. Inverter B does not physically
exist (~2026-09-12); `plantsim.INVERTER_B` is A COPIED, `measured=False`. Every
two-inverter figure in this record is two copies of A, and the lag sweep is a
SENSITIVITY STUDY ON A HYPOTHESIS ABOUT B, not a measurement of it. The old
wording - "MEASURED, not felt" - overstated exactly that, and "the RAMP does not
move it at all" was too strong: halving it is worth 0 s at A's lag and +5 s at
twice it.

Touched: DECISIONS/SAFETY-42 §1 and §3.3, app/delivery.py's provenance comment,
config.yaml's `delivery_hold_s` block, both translations, CHANGELOG Unreleased.
26/26 suites pass.

glenn schrooyenandClaude Opus 5 86bdf49332 PKG-12: bump 0.8.0 -> 0.9.0, so the five merges behind it can actually ship
checks / unit (pull_request) Successful in 6m14s
⚠️ MINOR FOR NEW FUNCTIONALITY, NOT FOR A BREAK, AND THAT DISTINCTION IS
CHECKED RATHER THAN ASSERTED. PKG-07 was minor because a config that started on
0.7.0 could be REFUSED on 0.8.0. Nothing of that kind is true here:

  - `options:` and `schema:` hold 71 top-level keys on both 06661c5 and HEAD.
    The one schema addition is a PER-ENTRY key, `capacity_kwh: float(0.1,200)?`,
    and the trailing `?` makes it OPTIONAL.
  - An unmodified 0.8.0-era config validates clean on 0.9.0. Measured through
    the shipped validator on both the flat single-inverter shape the reference
    install runs and an N=2 roster with no `capacity_kwh` on any entry: 0
    problems each.
  - OPT-09's two new refusals fire only on configs that USE the new key - an
    unparseable value, or the key stated on one entry and left empty on another.
    Neither can reach a config written before the key existed.

PKG-07's first draft justified its bump with an invented compatibility break and
review caught it. This one states what was measured, and the measurement says
existing installs upgrade untouched.

Contents since 0.8.0 (`06661c5`): UX-02 (`3d29993`), OPT-09 (`fdb3b69`),
PKG-09 (`fcaa724`).

⚠️ THE VERSION WENT UNBUMPED FOR THE THIRD TIME IN THREE DAYS - PKG-06 six
merges, PKG-07 six, this one five - and this time PKG-09's own tool caught it
during PKG-09's review rather than a person. The changelog carries OPT-09's
disclosed N=2 detection regression and points at the pre-deploy check.

⚠️ STILL NOT DONE, AND STILL NOT DOABLE FROM HERE: the live options have not
been checked against this version's validator. The gate reports exit 2 - NOT
CLEARED - rather than clearing, which is correct. Export the options from the
Supervisor and re-run before `ha apps update`.

Suite: 26 files, all pass.

glenn schrooyenandClaude Opus 5 f8e501393f OPT-09: the weights parameter nothing ever passed, and what it cannot do
`allocator.plan()` has taken a `weights` argument since ALLOC-01 and NOTHING
had ever passed one - main.py called `resolve()` without it and the arbiter
defaulted it to 1.0 per unit - so the site target was split 50/50 regardless
of what either pack could do. Two things now feed it, and they are different
kinds of thing:

  * a `pack` UNIT claim at P_SAFETY that CLOSES a unit's envelope at its own
    `bms_soc_floor` or at 100 % - a PERMISSION, obeyed absolutely, so an empty
    pack is not asked to discharge and its share goes to the sibling;
  * SoC-aware weights by ENERGY headroom in kWh - a PREFERENCE, which
    `_fill()`'s last-resort pass will override the moment the sibling saturates.

Measured (test_packshare.py part 8): at a load one pack cannot cover, the
weighted arm and the shipped arm command the IDENTICAL watts into an empty pack
and deliver the IDENTICAL watts. Only the envelope stops the ask, and what it
buys is not delivery - it is a reported `unmet_w` where the record used to read
impeccable. Weights are a comfort choice for STABILITY and NOT for DELIVERY.

Also: an optional per-entry `capacity_kwh` (schema change, all-or-nothing across
the roster, rule 9 refuses a partial one); per-pack arbitrage sizing, with the
sell side's no-op stated rather than hidden; and a 0 W trade refused by name,
because a 0 W arbitrage claim is a park order that outranks the loop.

SAFETY-42 and this card meet at one hazard from opposite sides - OPT-09 stops
the site ASKING a pack whose SoC says it cannot deliver, SAFETY-42 alarms when a
pack that said it could does not - and its end-to-end fixture moved as a result.
Its finding is unchanged and is now stated on the two quantities its rejected
discriminator actually reads.

Not filed at all at a roster of one: at N=1 every source routes to the site, so
the interval would bound the SITE TARGET, and SAFETY-25's decided Option A
stands untouched on the live install.

⚠️ INVERTER B DOES NOT EXIST. Its 4600 W / 20.48 kWh / 10 % are FROM DATASHEET
AND SERIAL, and `sim/plantsim.py`'s INVERTER_B is inverter A copied
(`measured=False`), so every two-inverter figure here is arithmetic or two
copies of A. No hardware was touched.

glenn schrooyenandClaude Opus 5 06661c5e17 PKG-07: bump 0.7.0 -> 0.8.0, because 0.7.0's own default is now a refused config
checks / unit (pull_request) Successful in 6m6s
Six merges landed behind an unbumped 0.7.0 - CI-06, SAFETY-38, SAFETY-39,
SAFETY-37, SAFETY-13, SAFETY-42. PKG-06 recorded this exact failure YESTERDAY
(bbc903b, 2026-09-05 19:23): the Supervisor keys the built image by `version:`,
so `ha apps update` against an unchanged version is a silent no-op and the box
keeps running the old tree. Catching it by hand a second time is the argument
for the automated check PKG-06's follow-up still owes.

MINOR rather than patch, and the reason is sharper than a semantic change:
SAFETY-39's validator rule 10 refuses an explicit `slew_w` above
SLEW_RAIL_FRAC x the site rail - 555.6 W on a 5000 W rail - and 0.7.0's own
SHIPPED DEFAULT was `slew_w: 1000` under schema `int(50,5000)`. An install that
never touched the key is refused on 0.8.0. Refusal is SystemExit(78); the
add-on does not start.

⚠️ AN EARLIER DRAFT OF THIS COMMIT JUSTIFIED THE BUMP BY CLAIMING `slew_w: 0`
USED TO MEAN "no limit" AND NOW MEANS "follow the rail". THAT WAS FALSE AND IS
REMOVED. The schema was `int(50,5000)` from the repo's first commit through
0.7.0, so 0 was never a legal value and never meant anything; and the old
`control.py` had no zero case - at slew_w=0 it pinned the command to its
previous value, freezing it, which is the opposite of "no limit". The widening
to `int(0,5000)` is a NEW capability, not a changed meaning. The bump is right;
the story told for it was invented - PROC-01's defect appearing in the very
commit that complains about process.

⚠️ AND THEN A SECOND ONE, IN THE SAME COMMIT: the text said PKG-06 was "three
days ago" when the two commits are about a day apart (2026-09-05 19:23 ->
2026-09-06 20:03). Caught in round 2 and corrected. Two invented facts in one
documentation-only change is the measurement PROC-01 wants, not an anecdote:
both were plausible, neither was load-bearing, and both would have shipped.

⚠️ THE PRE-DEPLOY CHECK THIS IMPLIES IS NOT DONE AND CANNOT BE DONE FROM HERE.
Whether the LIVE options survive rule 10 depends on the live `slew_w`, and the
options blob is only reachable through the Supervisor API, which needs a token
this session does not have; the HA REST API does not expose it and no entity
carries it. On record `slew_w` was set to 400 during the SAFETY-39 interim fix,
and 400 is below 555.6 - but that is a written record, not a reading, and the
value has been hand-edited since. Read the options and check them BEFORE
`ha apps update`. Exit 78 also takes the ingress panel down, because the add-on
serving it is not running.

The contents table now carries each merge subject's WHOLE claim. Two rows had
been trimmed to their flattering halves - SAFETY-39's "`gain` is the constant
that is still wrong" and SAFETY-42's "the discriminator the card asked for does
not exist" - and both are restored.

Separately, `## Unreleased` was a lie twice over: two headings by that name, one
spanning ~3000 lines across three releases, one from the 0.4.x era, and every
word under both is shipped and running. Retitled, not re-sorted; the split is
PKG-08.

Reviewed twice. Round 1 REJECTED for an empty PR - built in a clone a concurrent
agent was using, and "pushed" reported from the command's echo rather than from
the remote ref - and for the fabricated slew_w story. Round 2 APPROVED with the
date as a non-blocking finding, fixed here.

Claude 090a8ecc35 SAFETY-42 round 2: pin the two thresholds at a config that is not the shipped one
checks / unit (pull_request) Successful in 6m7s
THE BLOCKER. At the `delinquent()` call site, `self.tuning.saturation_w` ->
`250.0` (-19 B) was a survivor of all 23 suites. It is not an equivalent
mutant: two copies of inverter A, B wedged, `saturation_w: 1800` (inside its
own schema int(100,2000)) and a load of 1600 W put B's shortfall strictly
between the literal and the configured value - head names nobody, the mutant
names B. At the shipped 500 both name it, which is exactly why every fixture
in part 4 was blind: their gaps are all above both thresholds.

It matters beyond a mutation score. `delivery.py`'s MIN_W_IS_SATURATION_W note
and the `delivery_hold_s` block in config.yaml both promise an operator, in
shipped prose, that there is no fourth copy of a threshold to keep in step and
no way for the two to drift - raise `saturation_w` and this check moves with
you. A literal at the call site removes exactly that promise, silently, and
the promise is why the design was chosen over a `delivery_w` key.

ASKING THE SAME QUESTION OF EVERY OTHER NUMBER THIS CHECK READS FOUND A SECOND
SURVIVOR OF ALL 23 SUITES: `bms_floor=inv.bms_soc_floor` -> `10.0` (-13 B),
invisible because config.yaml's own example states 10 % and every fixture in
this file used it. Two arms bracket it: a pack at 15 % against its own 25 %
cut-out is cold and must stay unnamed (the literal names an empty pack), and a
pack at 8 % against its own 5 % cut-out is wedged and must be named (the
literal explains the fault away). One arm on each side leaves no constant at
all.

`delivery_hold_s` and `is_live()`'s window were ALREADY pinned - the fixtures
had to move them to run - and `LINK_STALE_S` has no option behind it, so
"pinned across a changed config" is not available for it and is not claimed.
DECISIONS section 9 enumerates all of it with the deltas and which check kills
which.

Verified in the CI image, tree mounted :ro, `python3 -B`, `__pycache__` purged
and counted before every run (TEST-15):
  R5 saturation_w -> 250.0                    -19 B  killed by part 4b(a)
  R6 bms_soc_floor -> 10.0                    -13 B  killed by part 4b(b), both arms
  R7 arm(self.delivery_cfg) -> DeliveryConfig()  -1 B  killed (already)
  R8 is_live(now) -> is_live(now, 3600.0)      +8 B  killed (already)
  R9 pack cut-out -> conjoined site floor    +105 B  killed twice
  head: 23/23 test files PASS, no bytecode written during the run.

No shipped behaviour changes: the only edits to app/ are comments.

glenn schrooyenandClaude Opus 5 706e625d99 SAFETY-42: a unit that stops delivering, and the discriminator the card asked for does not exist
A unit standing at a non-zero share and producing nothing is seen by NOTHING.
SAFETY-30's per-unit sign gate needs OPPOSITION on both sides of 250 W and a
unit at 0 W is not opposing, it is ABSENT. The site sum still agrees with the
meter in direction. Circulating power is exactly zero when one unit does
nothing. The only trace left is `reason == "saturated-freeze"`, which
clamp.py:93-96 documents as the alarm an operator learns to ignore. It is
HW-01's shape, which ran 6 h 25 m with all three layers spectators.

⚠️ THE CARD'S OWN DISCRIMINATOR WAS BUILT FIRST AND FALSIFIED, AND THAT IS THE
MAIN CONTENT. SAFETY-42 asks for "saturation persisting past N while
|grid error| > X, both derived". Run on the two-master rig it fails in BOTH
directions, and no (N, X) fixes either:

  FALSE POSITIVE  `plantsim.Plant.limit()` returns 0 W for a discharge command
      into a pack at its own floor, and a wedged unit produces 0 W too. Load
      2000 W, equal weights, 2000 W per-unit cap, 120 cycles: THE TWO ARMS ARE
      IDENTICAL ON ALL 120 in grid, site target, every share and every measured
      watt. Both saturated-freeze on 116 of them, both hold |grid error| over
      300 W on all 120 and settle at 1200 W, both read circulating 0.0 W. The
      predicate's inputs do not differ, so no threshold on them can differ. And
      "a cold pack at its floor must not alarm" is the card's own AC 2.

  FALSE NEGATIVE  the standing grid error is what a HEALTHY SIBLING ERASES.
      Load 800 W, same config, B wedged: over the last 30 of 200 cycles the loop
      is frozen on 30 of 30 while the worst |grid error| is 30 W, with B standing
      at +770 W and delivering 0 W. Any X above 30 W is silent for the whole run
      on the exact fault the card describes.

WHAT REPLACES IT. Per unit, for a discharge share, `share - measured`; readable
because of a reduction that only exists at N>=2:

    a unit is named while it is short by more than `saturation_w` with NO
    ACCOUNT for it, and the units in that state are a PROPER SUBSET of the units
    asked to discharge.

THE ACCOUNT keeps the cold pack out and is the only thing that can: the two
cases are identical in the power domain, so the discriminator has to be a
non-power fact, and there is exactly one - the pack's own SoC against its own
`bms_soc_floor`, asked through `peakguard.discharge_permitted()` rather than
transcribed. ⚠️ `bms_soc_floor` ALONE, not `pack_floor_pct()`'s conjunction with
`peak_soc_floor`: that floor bounds a money-saving discharge only and using it
would explain away a wedged unit anywhere between the two.

THE PROPER SUBSET keeps a whole-site cause out - a derate this add-on cannot see
hits every unit; one box that stopped listening does not - and it is what makes
this INERT AT N=1, by algebra rather than by a roster guard.

IT REPORTS. IT DOES NOT ACT, and the strongest argument is for acting. Dropping
the wedged unit from `live` genuinely recovers a site the shipped path does not:
at load 1500 W, kept in the split the site settles at 800 W with a 700 W error
and NEVER comes inside 100 W in 150 cycles (the freeze pins the target, so the
sibling's SHARE never grows); dropped, it delivers 1500 W from cycle 14. What
refuses it is that the only re-allocation this add-on can express is
all-or-nothing: a unit derated to 50 % is short by more than saturation_w with
nothing to explain it, so this detector names it too, and at load 3000 W
dropping it leaves the site delivering 2000 W against 2400 W kept - 400 W WORSE.
A partial re-allocation is what would make acting safe and the allocator cannot
express it. That is a card.

control.py is NOT MODIFIED. The freeze shapes the loop; this reports on it.

NUMBERS, MEASURED. The watts side is `Tuning.saturation_w`, read at runtime, so
there is no fourth CFG-03 copy and it cannot drift from the number the control
law itself calls "not following". `delivery_hold_s: 185` comes off 2640
closed-loop two-inverter runs in which nothing is faulty (6 gains x 5 slews over
the whole schema range, across load reversals, a flapping load and ASYMMETRIC
SPLITS - a family SAFETY-30's campaign did not have and the one that dominates
here) plus 1890 runs at a roster of ONE as the control:

    threshold   reversals   flapping   weighted   N=1 control
     * 500 W      20.0 s      0.0 s      30.0 s      0.0 s

The N=1 column is 0.0 s at EVERY threshold in all 1890 runs, and the flapping
column - the family that defeated SAFETY-30's site window - is zero too, because
a common stimulus makes both units short at once and the subset stops being
proper. ⚠️ The curve is NOT monotone (55.0 s at 250 W against 40.0 s at 100 W):
lowering the threshold can turn a proper subset into the whole roster and BREAK
the run.

⚠️ THE MARGIN IS MEASURED, NOT FELT, BECAUSE INVERTER B DOES NOT PHYSICALLY
EXIST. `plantsim.INVERTER_B` is A COPIED, `measured=False`, so every two-inverter
figure above is two copies of A. Sweeping a different second unit: the worst
legitimate episode is insensitive to B's RAMP (30.0 s at half A's) and scales
with its LAG - 45.0 s at twice A's measured 10 s, 90.0 s at four times it.
185 s is 6.2x the measured worst, 2.06x the four-times-slower case, 6.2x
LINK_STALE_S and 4.9x inside the 900 s quarter. Deliberately not 180, which is
SAFETY-02's site hold.

SAFETY-34. `unit/<name>/delivery_tripped` in the store, one notification id per
unit, re-raised on the first cycle of every process, cleared by the Start press.
No flat mirror: a rollback lands on a version that drives one actuator, where
this check is inert.

⚠️ SCHEMA CHANGE - `delivery_hold_s` joins options: and schema:, so this needs a
version bump before it ships. Additive and defaulted, so an existing options blob
stays valid.

STATED GAPS: charge shares are not graded (no configured charge ceiling exists,
so a constant-voltage taper cannot be explained and arming it would fire on every
maintenance charge); every unit wedged at once is not caught (the subset is not
proper and no instrument here separates that from a plant that cannot).

adminandClaude Opus 5 5d7e275df4 SAFETY-39: slew_w is a ratio to the rail, and gain is what is still wrong
checks / unit (pull_request) Successful in 5m16s
`slew_w: 1000` was derived on 2026-08-22 against a clamp of 1500 W, where
"capping how far the loop can jump ahead of the inverter" was true because the
rail itself bounded the excursion. The live install went to max_w 5000 and the
constant did not move, so the loop crosses its whole output range in 10 s
against a plant NOTES.md §5.10 measured at ~18 s. Measured on the owner's system
2026-09-05 11:43-11:46: a 3.4 kW export drove the setpoint 380 -> 5000 W in five
2 s 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. Nothing was broken; the rail moved.

REPRODUCED FIRST, and one half of it is not reproducible at all. On
plantsim.Plant and on an independent in-repo model: the setpoint stepping a full
1000 W per tick to the rail (48 of 51 export steps), and the meter crossing from
export into import. The -5154 W figure is NOT reproducible in either model,
because both clamp the plant at its rating - so the card's AC "battery no longer
exceeds max_w in simulation" is unfalsifiable and was rewritten rather than met.

THE DELIVERABLE IS THE RELATIONSHIP.
  SLEW_RAIL_FRAC = LOOP_TICK_S / PLANT_SETTLE_S = 2 s / 18 s = 1/9
  slew_w = 0 now means FOLLOW THE RAIL - SLEW_RAIL_FRAC * max_w - exactly as
  integrator_max_w = 0 already means follow max_w. It is the shipped default:
  222 W at max_w 2000, 556 W at 5000, 1067 W at a ~9600 W two-inverter site.
  validate.py rule 10 refuses an explicit value faster than that, graded against
  sum(unit_caps(opts)) - the roster sum, i.e. Controller.site_max_w - so a
  second inverter moves the bound with no operator action.

VERIFIED BY BREAKING IT: restoring slew_w 1000 at max_w 5000 is refused, and the
refusal names the rail, the crossing time, the measurement and what to do.
Equality, one watt of slack, the live interim 400 and slew_w 0 at every rating
all still start.

GAIN IS THE CONSTANT THAT IS STILL WRONG, and it is NOT changed here. Over 51
export steps the over-absorption is FLAT in slew (958 W at 1000, 1081 W at 250)
and monotone in gain (987 W at 0.6, 876 at 0.3, 435 at 0.2): slew_w bounds the
OUTPUT, while the integrator moves gain*error per cycle and reaches a 5000 W
rail in under three ticks whatever the slew is. Two control-law constants moving
in one release on a running house makes the next measurement uninterpretable.

⚠️ N=2: the site rail becomes sum(max_w) ~ 9600 W (inverter B FROM DATASHEET AND
SERIAL, not measured, and sim/plantsim.py's INVERTER_B is A copied), and the
enforced ratio produces 1067 W there automatically. But a growing rail LOOSENS
this bound, and the >= 900 W symptom goes stale at N=2 the same way the constant
did - both stated in the record rather than left to be discovered.

Nothing reached the inverter. The live install still runs the interim slew_w 400
applied by hand on 2026-09-05, which rule 10 accepts unchanged.

glenn schrooyenandClaude Opus 5 d8e02ad3f8 PKG-06: bump 0.6.0 -> 0.7.0, because the schema changed and nobody bumped
checks / unit (pull_request) Successful in 5m2s
Six merges landed since 0.6.0 was deployed and the version never moved.
Disk and box both read 0.6.0, so `ha apps update` would have been a
NO-OP: Supervisor keys the built image by `version:`, and the update path
installs `version_latest`, which cannot differ from `version` without a
bump. Found while pre-checking the deploy, not after it silently did
nothing.

⚠️ MINOR RATHER THAN PATCH, BECAUSE THE SCHEMA CHANGED. SAFETY-32 added
`bms_soc_floor: int(0,50)` as a REQUIRED per-entry key on the `inverters`
roster - no trailing `?` - so a config declaring a roster and omitting it
on any entry is refused at startup. Verified against the deployed
2d025ee: the per-entry schema went from 6 keys to 7. Top-level options
and schema are unchanged at 63 each.

An install running `inverters: []` is unaffected, which is every
single-inverter install including the reference one: the flat
`bms_soc_floor` still describes the one pack. But CFG-04 recorded the
rule this follows - "a schema change without a bump is a schema nobody
reads" - and this is exactly that shape.

The CHANGELOG gains a 0.7.0 section listing the six merges by SHA. It
also records, rather than papers over, that 0.6.0 was never sectioned:
its content sits below the new heading because the earlier bump shipped
without cutting a section. Splitting it retroactively would mean guessing
a boundary; the deployed 0.6.0 is 2d025ee and the table says what is new
since it.

Full suite: 21 passed, 0 failed.

Claude Opus 5 fef6ef20a4 UX-01: translate the add-on config, and order it by task
checks / unit (pull_request) Successful in 5m1s
The add-on had NO translations/ directory, so Home Assistant fell back to
rendering the raw option KEYS. An operator opening Configuration read
`unit_sign_disagree_w`, `saturation_cycles`, `integrator_max_w` - seventy of
them, in file order, with no description and no way to tell a constant derived
from 1890 closed-loop test runs from their own inverter's rating.

⚠️ PRESENTATION ONLY. Not one default, not one schema range and not one line of
behaviour moved. The 175 non-comment lines of config.yaml are byte-identical to
release/1.0's, reordered; the only comment lines that changed are the group
banners and five sentences whose "above"/"below" the reorder made false.

* translations/en.yaml and translations/nl.yaml: a name and a description for
  all 70 options and all 7 per-entry keys of the `inverters:` repeatable
  section. The Dutch is written for a Flemish homeowner - afname/injectie,
  kwartierpiek, capaciteitstarief - not transliterated from the English.
* ⭐ Every derived constant says WHERE IT CAME FROM and whether to touch it.
  `unit_sign_disagree_s` cites its 1890 closed-loop runs (SAFETY-30);
  `circulation_w` its 924 runs and the measured 400 W knee (SAFETY-31);
  `meter_freeze_s` its 2399 s capture (SAFETY-18); `bms_soc_floor` register
  0x0560. The two numbers that are the operator's - max_w and peak_cap_w - say
  "THIS IS YOUR NUMBER". `cycle_cost_threshold_eur`, which is neither, says it
  is an open product question (OPT-08).
* config.yaml reordered into task order in BOTH halves, comments carried with
  their keys: hardware -> meter -> ratings and limits -> tariff -> maintenance
  -> safety -> advanced.
  ⚠️ test_inverter.py:1788's trap is PRESERVED: the nested per-entry `max_w:`
  still precedes the flat one under `schema:`, and `inverters: []` still ships
  in the `options:` half. Moving the nested block below the flat one is a 1-byte
  edit; it was run and goes red in test_inverter.py and test_translations.py.
* tools/supervisor_shape_probe.py section F MEASURES the result against
  ghcr.io/home-assistant/amd64-hassio-supervisor:2026.08.0 - Supervisor's own
  _read_app_translations(), its own UiOptions, and the frontend's label
  resolution transcribed from the shipped bundle - and prints every rendered row
  in both languages. `all cases passed`, exit 0.
* ⚠️ ONE MEASURED NEGATIVE RESULT, NOT GLOSSED: the per-entry keys inside the
  `inverters:` section still render RAW on frontend 20250925.1, because a
  list-of-objects goes to ha-selector-object and the converter sets no `label`
  and no `translation_key`. The `fields:` translations are shipped and validated
  - that is Supervisor's own shape for this - but this card does not claim they
  reach the screen. The `inverters` label and description do.
* test_translations.py: a translation naming a non-existent option, or an option
  with no translation, fails CI - both directions, both languages, top level and
  per entry. Mutation-tested BOTH WAYS: eleven in-process mutations each
  required to NAME the key they broke, plus a negative control; six more run on
  disk through the purge-and-re-read protocol. Two of the eleven are the ones
  that cost the WHOLE FILE rather than one label - an unrecognised top-level
  block, and a `network:` value that is not a string. Supervisor drops a file
  that fails SCHEMA_APP_TRANSLATIONS with only a log warning, so those silently
  return the entire tab to raw keys; neither is reachable through the
  `configuration:` coverage, which is why they were hunted for and closed.
* tools/translations_lint.py is the hand parser CI needs (no PyYAML in the
  add-on image) and the probe grades it, key by key and string by string,
  against Supervisor's own loader. It is strict and RAISES rather than skipping;
  nine malformed shapes prove it.

Full 20-file suite green (19 existing + test_translations.py).

adminandClaude Opus 5 f9e7fbf86d SAFETY-32: bms_soc_floor per pack, rule 8 per unit
`bms_soc_floor` describes A BATTERY, not a site. At two packs of different
models the cut-outs differ, and one number for both graded the shallower pack
against the deeper one's BMS - so a site with cut-outs of 10 % and 30 % under
`peak_soc_floor: 20` STARTED, and the guard would command a forced discharge
that pack B's BMS, not the operator's floor, is the thing that stops. That is
rule 8's own failure mode, reached through rule 8.

Scoped to the card's third bullet, per its PM PROOFREAD: the aggregate
anti-windup (DEV-02) and per-instance `achievable_w` (CFG-04) were verified as
already shipped and are untouched.

* config.yaml: `bms_soc_floor: int(0,50)` REQUIRED per `inverters:` entry.
  Nothing is inherited; the flat key stays the single-inverter shape's own
  cut-out. A per-entry DEFAULT was declined - a default is one number for every
  pack, which is this card's defect - and the decision is recorded.
* inverter.py: `Inverter.bms_soc_floor`; an entry that states none gets None,
  not a borrowed number and not 0.0 (the most permissive value the key has).
* peakguard.py: `Pack`, `pack_floor_pct()`, `pack_permissions()`,
  `binding_soc_floor()`. `discharge_permitted()` is unchanged and is still the
  one place the question is answered.
* validate.py: `unit_bms_floors_indexed()` carries the ROSTER index; rule 8
  grades EVERY unit and NAMES the one it refuses. Graded with the offender
  SECOND and with the same two numbers in the other order.
* main.py: `Controller.packs`; `decide(soc_floor=...)` is the per-pack
  reduction of the same option; the floor-limited notification names the pack
  that stopped the site. `pack_floor_soc` - the emptiest pack, and its
  None-on-missing behaviour - is untouched.
* tools/supervisor_shape_probe.py: RE-RUN and repaired. The required key broke
  §C and left §D printing PASS on a refusal about a different key. §D is now an
  isolated counterfactual over an accepted merged baseline, one key varied,
  asserting the key name. `all cases passed` on 2026.08.0.

Stated rather than hidden: under any config rule 8 accepts the per-pack FLOOR
reduces to `peak_soc_floor` for every pack. The reduction is written for
`unit_caps_indexed()`'s reason and graded on both sides - 1775 rule-8-valid
pairs answer the option, the pair rule 8 refuses answers the cut-out.
`peak_soc_floor` is still one number for the site, so the "deeper pack
needlessly withheld" half is filed as an open question, not closed.

Full 19-file suite green. Twelve source mutations through
tools/mutation_run.sh: eleven red, one argued survivor. The battery also found
`_flat_bms_floor()` defaulting in two places, each covering for the other.

No measurement of inverter B appears anywhere: it does not exist yet. Every
second-pack figure is simulated and labelled.

glenn schrooyenandClaude Opus 5 a9993aeda2 SPIKE-04a: inverter B is 4600 W FROM ITS DATASHEET, and the copies are pinned
checks / unit (pull_request) Successful in 4m51s
The desk half of SPIKE-04. No control behaviour changes; this is documentation
and the check that stops it drifting again.

Three places stated inverter B's rating - config.yaml's commented roster
example, DOCS.md's, and tools/supervisor_shape_probe.py's "a blob an operator
would POST" - and all three said 3000 W, a number nobody had measured or read
off anything. The owner supplied B's model and serial on 2026-09-04: a GoodWe
GW5048D-ES, serial `55048ESU22AW0992`, max charging and discharging power
4600 W. Serial characters 6-8 are `ESU`, platform 105 / AA55, so SPIKE-01 does
not gate this site. All three copies now read 4600.

⚠️ 4600 W IS FROM A DATASHEET AND IS NOT A MEASUREMENT, and the one ambiguity
is recorded rather than guessed. The datasheet prints it under BATTERY INPUT
DATA, so it is probably DC, while max_w is graded against 0x0518 - the
inverter's own AC power. If it is DC the AC ceiling is nearer 4324 W. Neither
reading is written in as fact; SAFETY-20's min(max_w, dev_max) already bounds
it correctly under either, once dev_max is read off the unit, so `max_w: 4600`
is what an operator should configure today. goodwe/NOTES.md §1.1b carries the
full record with the date and the method on every figure.

A NEW CHECK, BECAUSE A DOCUMENTATION FIX WITHOUT ONE DRIFTS AGAIN.
test_validate.py now pins all three documented rosters: findable, in agreement,
and equal to 4600 - with an explicit len(...) == 3 guard so that a regex which
stopped matching cannot leave "they all agree" green on the two sites still
read. It also grades the PROVENANCE beside the number (the datasheet, the
0x0518 it is graded against, and the 4324 W the DC reading would make it)
WITHIN 2500 characters of the roster rather than file-wide.

⚠️ The first version of that provenance check searched whole files and was
ALREADY VACUOUS on two of them: 0x0518 appeared once in config.yaml and once in
DOCS.md before this card, for unrelated reasons, so `"0x0518" in src` was green
no matter what happened next to B's rating. That is a check whose data cannot
reach the failure it names, in the file that exists to complain about them. It
is fixed, and the window is what fixes it - deleting the caveat beside the
number now goes red even where the same token survives elsewhere in the file.
The windowed version immediately found that the DOCS.md caveat did not name
0x0518 at all; DOCS.md now says it.

Four mutations, bytecode purged and counted at 0 before and after each, all
RED (two of them 0-byte deltas that change a printed answer):
  M1  probe's operator blob 4600 -> 3000        0 B   RED (value + agreement)
  M2  DOCS.md's DC/AC caveat deleted         -157 B   RED (provenance)
  M3  config.yaml alone 4600 -> 4324            0 B   RED (agreement)
  M4  probe entity renamed, regex finds nothing       RED (the vacuity guard)
Restored, green again. The probe itself was re-run against Supervisor
2026.08.0's own AppOptions validator with the 4600: all cases passed, exit 0.

⚠️ THE TEST FIXTURES KEEP 3000 W ON PURPOSE AND NOW SAY WHY AT THE LINE.
test_inverter.py, test_maintenance.py, test_peakguard.py and test_watchdog.py
build a second inverter at 3000 W against A's 5000 W. The only property those
checks consume is that B's number is unmistakably not A's, and the real pair is
a 400 W gap - narrower than slew_w, inside the range where an off-by-one-unit
bug and ordinary control arithmetic produce indistinguishable numbers.
Collapsing them onto the real values would buy realism those checks do not use
and cost them their separating power, which is exactly what test_peakguard.py's
own §10g PRECONDITION exists to prevent. Their comments no longer call 3000 W a
hypothesis about B's rating; they call it illustrative, and not a placeholder
either - the placeholder era ended on 2026-09-04.

Also recorded in the changelog for the cards that own them: 94 % battery-to-AC
=> ~88 % round trip => ~360 W burned continuously to circulate 3 kW, which is
the number SAFETY-31 argues its threshold from without having one; < 13 W night
self-consumption per unit, which nothing accounts for; and the A/B asymmetry in
opposite directions (~33 % more energy, ~8 % less power), which means MAINT-05's
12 h drain timeout was derived on A and should be re-checked against B.

⚠️ Honest survivors:
- goodwe/NOTES.md §1.1b, where all of this is actually recorded, is graded by
  nothing here. Rewriting its 16 occurrences of 4600 to 3000 and turning every
  FROM DATASHEET label into MEASURED ON THE UNIT leaves all 19 files GREEN.
  This CI cannot fetch admin/goodwe - private, and GITHUB_TOKEN is minted for
  this repository only, as .gitea/workflows/checks.yml already states - so the
  cross-repo check is not buildable here.
- No check can see whether 4600 is the RIGHT number. Everything above pins a
  datasheet reading against itself. Only the bench half of SPIKE-04 can say
  whether the unit agrees, and the DC-vs-AC ambiguity is the live example.
- The constant is still named B_RATING_HYPOTHESIS in four test files, which
  reads as a hypothesis about B's rating when it is now an illustrative
  fixture. It is left alone deliberately: renaming ~20 sites across
  test_peakguard.py and test_inverter.py would collide hard with the open
  SAFETY-32 pull request, which rewrites 1255 lines of the first. The comment
  directly above each definition says what the value is and is not.

Suite: 19/19 green in goodwe-addon-ci, mounted :ro, bytecode purged and
verified 0 before and after.

glenn schrooyenandClaude Opus 5 ae21b71824 Merge release/1.0 into SAFETY-30
checks / unit (pull_request) Successful in 4m39s
CFG-04 (#45) merged first and moved the base. Two conflicts, both resolved
as the union of the two sides:

- app/main.py: an import-block collision. CFG-04 added validate_unit_ranges
  to the .validate import; SAFETY-30 added AGAINST_METER, AGAINST_OWN_POWER,
  SIGN_OPTION_DEFAULTS and SignWatchdog to the .watchdog import. Neither
  side dropped anything, so the resolution keeps both lists whole.
- CHANGELOG.md: two adjacent new entries under ## Unreleased. Both kept.

Both sides also independently rewrote large parts of test_peakguard.py
(60 and 47 insertions against the merge base) and git merged them
textually, so the full suite was run on the MERGE RESULT rather than
inferred from the two parents: 19 passed, 0 failed, twice.

One caveat recorded rather than hidden: test_peakguard.py failed once
during the first sequential full-suite run and then passed 10/10 in
isolation and in two further full runs on this same tree. It passes on
both parents too, so this is the pre-existing flakiness CFG-04 already
disclosed, not a merge defect - it is timing- or load-sensitive. It sits
on the required CI context and can therefore block an unrelated merge at
random, which wants a card of its own.

adminandClaude Opus 5 f000547518 SAFETY-30: grade each inverter against its own power, and the site's total against the meter
checks / unit (pull_request) Successful in 4m38s
THE DEFECT, in one line. `inv.sign_wd.evaluate(stood, self.grid, ...)` compared
the command THIS controller put on ONE actuator against what the WHOLE SITE is
exchanging with the network. At a roster of one those are two views of the same
thing - specs.md §6.2's identity - and that is what makes the check sound and
what earned it the best record in the safety table (NOTES.md: 93 % agreement
while healthy against 4 % during runaway, four observed episodes, zero false
positives). At two inverters they are not, and it fails in BOTH directions:

  FALSE TRIP  inverter A commanded -1500 W while the meter reads +1500 W is
              evidence of nothing when inverter B is discharging 3000 W exactly
              as told. Nothing is faulty and the highest-value check fires.
  MISSED      the converse, and it is worse. A unit commanded +1500 W and
              MEASURED at -1500 W, beside a sibling at +1500 W, leaves P1
              exactly where a healthy site leaves it. The summation destroys the
              evidence and no threshold recovers it.

DEV-02 had already shipped the per-INSTANCE half - one SignWatchdog per
inverter, namespaced latch, a trip on B no longer latching A. What was left was
the COMPARISON, and it is two questions rather than one:

  PER UNIT  this unit's standing command against ITS OWN measured power
            (`Inverter.batt`, holding register 0x0518, per-instance since
            DEV-02). Conclusion: "the actuator I am driving is not doing what I
            told it" - a fact about one device, so the remedy stays the per-unit
            `failsafe` SET that arbiter.CLAIM_SCOPE has classified SCOPE_UNIT
            from the day it was written. That entry read "the evidence is
            site-wide and the remedy is not"; the first half is now simply true.
  SITE      the SUM of the standing commands against the meter, as a new
            `sign_site` SET at P_SAFETY on the site actuator, latched under flat
            `site_sign_tripped` / `site_sign_reason`. This is the 2026-08-20
            fault day and NO per-unit check can see it, because every inverter
            may be faithfully executing its share of a number that is itself
            wrong. It stops every inverter and the banner names the site.

WHAT IT IS NOT, said here because two guards that overlap without saying so is
how a false-alarm generator gets built. It is not SAFETY-31: circulation.py
compares the units AGAINST EACH OTHER and catches them pushing power THROUGH
each other, which nets to zero at the meter and about which no single command is
evidence. This compares each unit against ITS OWN COMMAND. They overlap in
exactly one scenario - a unit reversing while its sibling pulls the other way -
and test_watchdog.py asserts on that fixture that both fire and what each
concludes. It is also not the saturation freeze, which is a MAGNITUDE test
(|command - measured| > 500 W) that shapes the loop and fires on a merely
saturated unit; this is a DIRECTION test that latches and parks one.

THE FOUR NUMBERS, RE-DERIVED AT TWO INVERTERS - one carried with a justification
and one refused. 1890 closed-loop runs on admin/goodwe's TEST-19 two-master rig
in which NOTHING is faulty, swept over the whole range config.yaml accepts for
`gain` and `slew_w`, across load reversals with write staggers and flapping
loads, and RUN AT BOTH ROSTERS so the N=1 arm is the control:

  unit_sign_disagree_w  250   `saturation_w / 2`. The check gates on both sides,
                              opposed, so the smallest gap it can see is 500 W -
                              exactly where compute()'s own anti-windup test
                              already says the inverter is not following. It
                              cannot fire on a divergence the control law calls
                              ordinary tracking. Worst legitimate opposition at
                              250 W: 10.0 s; the curve is nearly flat, because a
                              unit's own power chases its own command.
  unit_sign_disagree_s   85   8.5x that 10.0 s, 2.8x the firmware's own 30 s
                              link veto (inverter.LINK_STALE_S), under half the
                              180 s site hold.
  site_sign_disagree_w  300   CARRIED. Its argument is the meter's noise floor
                              and the 15 W deadband; the roster touches neither,
                              and the campaign agrees - the gate opens in 994 of
                              1050 runs at two inverters and 955 of 1050 at one.
  site_sign_disagree_s  325   NOT CARRIED, and this is the number the card
                              exists to not assume. The worst legitimate
                              crossing at 300 W is 110 s with one inverter and
                              215 s with TWO, because the command must travel a
                              rail that is the roster sum at a `slew_w` that is
                              not - reachable at gain 0.05, slew_w 50 and a
                              2.2 kW load reversal, all schema-legal. 180 s
                              would have shipped a false trip. 325 s is 1.51x
                              the measured worst, inside the 900 s billing
                              quarter and inside every episode of the fault day.

AT ONE INVERTER NOTHING CHANGES, and "nothing" is asserted rather than assumed.
The two questions are the same sentence there, so only the detector that shipped
is armed: same comparison against the meter, same 300 W / 180 s, same reason
string byte for byte, same namespaced latch and flat rollback mirror, same
`failsafe` claim, same banner, same single status row - and the site detector is
NEVER CALLED, counted on the object over twelve cycles.

VERIFIED BY BREAKING IT. Thirteen mutations on fresh per-mutation trees with no
__pycache__, mounted :ro, with the battery refusing to report at all unless the
baseline is green. Twelve red on the first pass. M4 - the site half armed at N=1
as well - SURVIVED, because the check read `disagree_since is None` and the unit
detector trips first, parks the inverter and leaves the site standing at 0 W:
the assertion ran, the sentence was true, and the data could not reach the
failure it named. Replaced with a call counter on the object; M4 is red now.
Recorded as a survivor in DECISIONS/SAFETY-30-per-unit-sign.md §5, with the
first battery's own RED BASELINE - a shared mutation directory read mid-copy -
discarded rather than reported.

RECORDED, NOT FIXED: the site comparison is defeated by a square-wave load whose
half period is about one control cycle, which holds it opposed for ~1000 s. The
N=1 control arm is what makes that interpretable - it is identical at the roster
this add-on ships, so it is a property of comparing a lagged command against a
meter and has nothing to do with the second inverter. It wants an alternation
test rather than a number, and a card of its own.

SAFETY-24's lo-only asymmetry proof re-run unchanged: 1296 combinations, 0
negative floors, `hi` +inf on every claim, every claim on the SITE actuator.

adminandClaude Opus 5 6b85acb0f1 CFG-04: an operator can declare a second inverter, and the shape was measured
checks / unit (pull_request) Successful in 4m30s
DEV-02 made every per-device value per-instance - rating, SoC, watchdogs,
heartbeat, store keys - so the code stopped assuming one inverter. The options
schema did not. `build_roster()` returned a list of exactly one and said so in
its own docstring, and there was no `inverters:` key for an operator to write,
so the roster could only ever be a roster of one.

THE SHAPE, AND WHY IT WAS MEASURED RATHER THAN CHOSEN

config.yaml had no list-of-objects anywhere, and `static_profile` carries a
whole tariff structure as a JSON string in a `str?` precisely because a nested
schema was doubted. That is a question about somebody else's software, so it was
answered by running it: `tools/supervisor_shape_probe.py` (committed) runs
Supervisor 2026.08.0's OWN `AppOptions` validator and `SCHEMA_APP_CONFIG`, out
of the release image, against this repository's config.yaml. 2026.08.0 is the
version the live install reports. The full transcript and the argument are in
DECISIONS/CFG-04-inverter-roster.md.

It accepts the list, enforces per-entry types, refuses a missing `name` /
`setpoint_entity` / `max_w` BY NAME, renders the option in the UI as a
repeatable section, and drops the key with a warning under an older schema - so
a downgrade is not the forward trap in reverse.

⚠️ AND THE `inverters: []` DEFAULT IS LOAD-BEARING, WHICH IS THE MEASUREMENT
THAT MATTERED MOST. Supervisor answers `Missing option 'inverters' in root` for
an options blob that has no such key - which every existing install's has, since
the key did not exist when they were written. `App.options` is the shipped
`options:` block deep-merged with the operator's stored one, so the empty
default is the difference between an upgrade nobody notices and an add-on that
cannot start with a schema pinned to the version that would fix it. That is
docs/deploy-rollback.md §4's trap in the FORWARD direction, found before it was
sprung. The merger was checked too: lists override rather than concatenate, so a
non-empty default could not have grown a roster behind the operator's back.

NOTHING IS INHERITED, WHICH IS DEV-02 RESTATED AS A CONFIG RULE

`name`, `setpoint_entity` and `max_w` are required of every entry. An entry that
omits `soc_entity` has no SoC sensor; it does not borrow the flat one. A
three-line fallback would have rebuilt the sibling-grading defect DEV-02 spent a
card removing, in YAML. Defaults still live in exactly one place (CFG-03):
there is no per-entry default anywhere, because there is no optional per-entry
number. A flat `setpoint_entity` left set beside a declared roster is refused
rather than ignored - it names an actuator nothing will write.

TWO PERMISSIVE READERS IN SHIPPED CODE, AND THREE MORE IN THE CHECKS

  validate.py rules 5 and 6 compared their thresholds against the FLAT `max_w`.
  At a roster of two 2000 W units with `max_w: 5000` left over from a
  single-inverter install, `sign_disagree_w: 3000` passed rule 5 while
  SAFETY-02's watchdog could fire on NEITHER unit - rule 5's own failure mode,
  reached through rule 5. They read `unit_caps()` now, which at one inverter is
  `[max_w]` exactly.

  main.py's `run_control()` re-ran the device-rating check behind
  `if self.o.get("setpoint_entity")` - the flat key, which a roster leaves blank
  - so on a two-inverter site no inverter's `max_w` was graded against the
  device it is written to, and the skip was silent. `validate_unit_ranges()`
  grades each unit against its own ESPHome and runs unconditionally.

  test_peakguard.py's `read_option()` and `_schema_bound()` and
  test_inverter.py's `read_schema_max()` matched a STRIPPED line and took the
  first hit, so the nested per-inverter `max_w:` began outranking the flat one -
  silently, and correctly, because the two bounds are the same int(100,5000)
  today. A reader that is right by coincidence is this project's named failure
  mode. All three are anchored at exactly two spaces now; the file's two halves
  disambiguate `peak_cap_w` instead of first-match, and an ambiguous key raises
  rather than picking one. test_tariff.py's copy of the idiom went with them.

THE AUDIT IS A CHECK, NOT A PROMISE

test_inverter.py part 11 finds every config.yaml-reading function in the suite -
transitively, because two of the readers CFG-04 had to change never name the
file - EXECUTES each against a synthetic two-inverter config.yaml whose
per-inverter numbers differ from its flat ones, and fails if any answers with
the per-inverter value. The table is not maintained by hand: the signature
decides, so the eleventh reader is named on its first run. config.yaml declares
`inverters:` BEFORE `max_w:` on purpose and part 11 asserts that ordering, so
the trap stays baited.

SAFETY-28's `actuator_writers()` needed no change - it was already a structural,
case-folding census - but until now there was no configuration in which two
writers on one actuator could be WRITTEN DOWN. There is now, and it is refused.

VERIFIED BY BREAKING IT

Ten mutations run through tools/mutation_run.sh and observed red, listed in
test_inverter.py part 12 with the check that bites each. Two survived the first
run and the CHECKS were changed, not the table: the inheritance check had blank
flat keys, so "inherited" and "not inherited" were the same empty string; and
the `run_control()` check asserted a SOURCE LINE was present, which re-indenting
it does not remove. Both are recorded in MUTATION.md's "the check's data cannot
reach the failure it names" section, which now carries two more habits: assert
on behaviour rather than on source text, and give a check whose failure mode is
a hang a deadline.

19/19 green in the goodwe-addon-ci image. The one-inverter path is byte-
identical: the whole existing suite runs unmodified against it.

Version bumped to 0.6.0 - the Supervisor keys the built image by `version:`, so
a schema change without a bump is a schema nobody reads.

adminandClaude Opus 5 7ef3d23245 SAFETY-31: measure circulating power, which nets to zero at the meter
checks / unit (pull_request) Successful in 4m28s
Inverter A charging at 3 kW while inverter B discharges at 3 kW nets ~0 W at
P1. The site reads idle while both packs are cycled through two round-trip
conversion losses continuously, for no benefit, and the wear is real.

NOTHING EXISTING CAN SEE IT, AND THAT IS STRUCTURAL. Every guard in this
add-on is a consumer of the NET figure at the grid connection: SAFETY-02's
sign watchdog gates on abs(grid_w) > 300 and the gate never opens at a netted
zero; the peak guard and the capacity tariff both bill grid exchange.
Circulating power is precisely the component of per-inverter power that the
sum destroys, so no threshold on any existing detector could reach it.

WHAT ALLOC-01 ALREADY COVERED, AND IS NOT RE-IMPLEMENTED HERE. Its AC 7
shipped the sign-coherence gate (allocator.REFUSE_SIGN, graded by
test_alloc.py part 6): an allocation whose shares carry two signs is REFUSED,
both units named, no shares returned. That is the COMMAND half - the allocator
can no longer command circulating power. This commit is the MEASUREMENT half:
circulation the allocator NEVER COMMANDED.

  app/circulation.py   the sensor and the trip
  main.py              site_circulating_w, the evaluation, the claim, the alarm
  arbiter.py           `circulation` classified SCOPE_SITE, with the argument
  store.py             a flat, site-level durable latch
  mqtt.py              sensor.goodwe_circulating_power
  config.yaml          two options, two schema ranges, CFG-03 discipline

THE SENSOR: sum(|Bi|) - |sum(Bi)|. Zero when the units pull the same way,
2*min(|Ba|,|Bb|) when they oppose. DERIVED FROM MEASURED PER-INVERTER POWER -
Inverter.batt, register 0x0518 - and never from the allocation record. The
cheap version would be simpler and worth nothing: ALLOC-01's gate already
guarantees the record is sign-coherent, so a record-derived sensor reads zero
BY CONSTRUCTION and can only confirm that the allocator agrees with itself,
which is the third failure mode MUTATION.md names. What this catches is a unit
ignoring or lagging its share, a stale share still being executed, a
maintenance or SAFETY-25 pin holding one unit while the loop drives the other,
or HW-01's power stage running its last instruction for 6 h 25 m with the
comms dead and the allocation record impeccable throughout. batt became
per-instance in DEV-02; before that this could not have been written.

VERIFIED BY MAKING ONE UNIT IGNORE ITS SHARE, on the TEST-19 two-master rig:

  S = -2500 W   shares a = -1250 W  b = -1250 W   <- record ok, ONE sign, sums
  MEASURED      A = -1250 W  B = +1000 W          <- hardware
  sensor over the RECORD     :    0 W
  sensor over MEASURED power : 2000 W  -> trips at 190 s

and the card's own scenario, A -3000 W against B +3000 W at zero house load:
the meter reads +0 W, the sensor reads 6000 W, and the shipped SignWatchdog's
predicate is FALSE on 30 of 30 cycles.

WHAT "ACTED ON" MEANS - decided, and recorded in DECISIONS/. The trip files
Claim.set("circulation", P_SAFETY, 0.0) on the SITE actuator: every inverter
to 0 W, latched. HW-01 established that commanding a wedged inverter achieves
nothing, so the remedy is not aimed at it. A circulating loop needs TWO
participants and one of them is THIS CONTROLLER, faithfully driving the
listening sibling into the one that stopped listening. Stopping (1) halves the
loop, which needs no cooperation from the wedged unit, and (2) - the more
important half - makes the residue VISIBLE at the meter instead of cancelled
at it, where every ordinary guard can finally see it. What it cannot do is
stop the wedged unit; the notification says so and names the isolator as the
last actuator. SITE-scoped because the quantity is defined over the roster and
is identically zero for any one unit - there is no fact of the matter about
which of two opposing inverters is the offender, so filing it per-unit would
invent an attribution and could park the only unit still listening.

THE WINDOW IS FROM THE RIG, NOT A ROUND NUMBER (AC 3). 924 closed-loop runs in
which NOTHING is faulty, over both families of legitimate opposition (7
reversals x 5 write staggers; 7 flap periods x 4 amplitudes), swept across the
whole range the schema accepts for gain and slew_w. Worst CONTINUOUS
legitimate opposition by threshold: 505.0 s at 100 W, 40.0 s at 250 W, 10.0 s
at 300 W, 5.0 s at 400 W and above. The knee is 400 W and it is the schema
floor - below it, ordinary operation holds the sensor over the line for
minutes and no window inside the 900 s billing quarter could tell that from a
fault. circulation_w 700 is 1.75x the knee, the headroom bought for inverter
B's ramp and lag being PLACEHOLDERS until SPIKE-04 measures them.
circulation_hold_s 75 clears three bounds: 15x the worst legitimate episode,
2.5x the firmware's own LINK_STALE_S veto, 12x inside the quarter. A momentary
opposition while one unit slews through zero is LEGITIMATE - writes are
serialised, so B's number lands up to a cycle after A's - and 0 of the 924
runs trip.

THE ALARM SURVIVES AN HA RESTART (SAFETY-34). persistent_notification is in
memory, which is exactly how the 2026-09-02 outage went unseen for 6 h 25 m
with the detector correct throughout. The latch is persisted to /data as flat
site-level keys and the notification is RE-RAISED on the first cycle after
every start, through the same code path as a fresh trip - two paths would be
two chances for the restart one to rot unnoticed.

AT N=1 NOTHING CHANGES (AC 5). |B| - |B| is 0 for every reading including one
nobody took, no claim is ever filed, the arbitration is byte-identical, and
the status page says n/a rather than claiming to watch something that cannot
happen.

VERIFIED BY BREAKING IT (AC 4). 18 mutations, all RED on named checks, each on
a freshly copied tree with no __pycache__ mounted :ro. M10 - the sensor
rewritten to read self.allocation.shares - is the headline: it takes AC 2 red.
Three mutations are +0 B, the risky delta, and are marked as such. One
equivalent mutant (the max(0.0,...) guard) is ARGUED rather than claimed:
searched over 700 000 rosters without a negative. One genuine SURVIVOR was
found and closed - publish() turning an unknown into a published 0 W, the
sensor's own None rule defeated one layer out. Full ledger in DECISIONS/.

arbiter.CLAIM_SCOPE gains its ninth source, so test_peakguard.py's 10f and 10g
tripwires and test_arbiter.py's scope table went red on the line the append
was written. Updated deliberately, with the argument, as their own comments
require. Full 19-file suite green.

glenn schrooyenandClaude Opus 5 d5b1ef19b3 CFG-03: give maintenance option defaults one source of truth
checks / unit (pull_request) Successful in 3m44s
Option defaults for the maintenance cycle were declared in three places that
could disagree, and MAINT-04 proved they already did. config.yaml shipped
`maintenance_charge_w: 2000`; main.py carried TWO `opts.get(..., 2500)`
fallbacks; MaintConfig's dataclass carried a third `2500.0`. So an options dict
with the key ABSENT was ACCEPTED by validate.py's rule 6 - which read 2000 -
and then built by main.py at 2500, against a 2000 W ceiling:

    options dict with maintenance_charge_w ABSENT, max_w=2000
      validate_startup_config  ->  []  (accepted, no problems)
      MaintConfig().charge_w   ->  2500.0
      arbiter.resolve()        ->  0.0 W, contradiction=True

That is the bug rule 6 exists to refuse, passing rule 6. It is unreachable on a
Supervisor install, which always supplies every key from config.yaml, and fully
reachable from sim/inject.py and from the test suite - which is where anyone
debugging maintenance actually works.

MAINT-04 shipped a TRIPWIRE and said so: test_validate.py pinned all three
literals and asserted the consequence through the real arbiter, so the
divergence could not silently widen or be half-closed. Its PASSING CONDITION
WAS THE BUG. Both it and validate.py's comment said to delete each other when
the divergence was closed. It is closed, so both are deleted.

THE DIVERGENCE WAS WIDER THAN ONE KEY. `maintenance_discharge_w` had the
identical three-way split (config.yaml 2000, MaintConfig 2500) and the card
named only the charge side. Closing one and leaving its twin would have
satisfied the numbers and left three sources of truth one line down, which is
the state that produced the bug. Both are closed, and so is the whole family:
all eight `maintenance_*` keys go through the same mechanism.

WHAT THE SINGLE SOURCE IS. config.yaml's `options:` block - it is what the
Supervisor reads and what the operator edits, so it wins by definition. There
is now exactly one in-code copy, `maintenance.MAINT_OPTION_DEFAULTS`, which is
TARIFF-02's `PRICE_OPTION_DEFAULTS` and SAFETY-24's `PEAK_OPTION_DEFAULTS`
pattern applied to the family that named the card - validate.py's rule 8 comment
already called that "CFG-03 read as a rule rather than as a complaint", so this
makes the rule hold where it was first broken rather than inventing a fourth
mechanism for one option family.

A MIRROR RATHER THAN A RUNTIME READ, and the reason is mechanical: the
Dockerfile copies `app/` and `run.sh` into the image and NOT config.yaml. The
running add-on cannot open the file it is configured by, so there is nothing to
read at 03:00 on a client's Pi, and a YAML-subset parser that could fail at
import is a new way for the add-on not to start. What makes the copy safe is
that test_maintenance.py pins every entry by READING the shipped file - drift is
a CI failure, not a comment.

EVERY OTHER SITE NOW DERIVES FROM IT OR HAS CEASED TO EXIST:

  * MaintConfig's eight dataclass defaults are indexed out of the mirror. No
    numeric literal survives in the class that held the third opinion.
  * `MaintConfig.from_options()` is the ONLY place in the add-on that reads a
    `maintenance_*` option. main.py's eight inline `opts.get(key, <literal>)`
    calls are gone: moving the read next to the mirror means the fallback cannot
    be anything but the mirror, because there is no literal in sight of it to
    disagree with. It uses `key in opts` rather than truthiness, so a shipped
    `false` or `0` is honoured instead of being quietly replaced by the default
    - this card's own bug in a different costume.
  * main.py's SECOND fallback site - the cheap-window charge floor at the
    P_MAINT_SHAPE claim - reads `self.maint.cfg.charge_w` instead of re-opening
    the options dict with its own literal. The Controller had already parsed
    this once in __init__; asking the object that owns it cannot drift from it,
    and the rate the shaping asks for can no longer be a different number from
    the rate the state machine drains at on the same install.
  * validate.py's rule 6 and its `maintenance_discharge_w` warning take their
    fallbacks from the mirror.

WHERE THE RANGE LIVES, STATED AND CHECKED. config.yaml's `schema:` block carries
`maintenance_charge_w: int(500,5000)` - a fourth declaration site of a different
kind. It is a BOUND, not a default, so it is not this bug; but leaving the
question open is how a fifth site arrives. The decision recorded in config.yaml
and in maintenance.py is: bounds live in the schema block ONLY, because the
Supervisor is what enforces them and the Supervisor reads only that file, so a
Python copy of `int(500,5000)` would be a place to disagree and nothing else.
test_maintenance.py checks both halves of that: every mirrored key must have a
schema entry - without one the Supervisor drops the option and the add-on
silently runs on the mirror instead of the operator's value - and every shipped
default must lie INSIDE its own range, since a default the schema rejects is a
config that cannot be re-entered once it is edited. What the schema grammar
cannot express is a relation BETWEEN keys (`maintenance_charge_w` against
`max_w`), which is exactly why rule 6 is written in Python and why it does not
belong in the mirror either.

THE REPLACEMENT CHECKS, AND HOW THEY WERE VERIFIED. test_validate.py's new
section exercises the same four consumers the defect ran through, the same way:
the validator ACCEPTS a dict with every maintenance key missing; a REAL
Controller built from that same dict holds 2000 W (through main.py, not through
a regex over its source); `MaintConfig()` answers 2000 W with no dict at all;
and the real arbiter emits `-2000 W, limited by supervised(max_w)` instead of
`0 W, contradiction=True`. test_maintenance.py pins the mirror to config.yaml in
both directions - equal values, and full coverage of every `maintenance_*` key
the file ships, so a ninth key cannot arrive unmirrored - and asserts the
consumers move as a RELATION rather than against numbers, reading MaintConfig's
defaults back out of `dataclasses.fields()`.

Each new check was verified by BREAKING the thing it watches and observing red,
this project's rule:

  1. config.yaml -> 1500, mirror left at 2000:  test_maintenance 1 FAILED,
     test_validate 4 FAILED.
  2. config.yaml AND the mirror -> 1500: green again, and every consumer moved
     together - MaintConfig() 1500 W, the Controller 1500 W, and the arbiter
     `-1500 W, limited by maintenance(cheap-window charge)` where it had said
     `-2000 W, limited by supervised(max_w)`. That is AC4: change the single
     source and watch the consumers follow.
  3. `charge_w: float = 2500.0` retyped into the dataclass: 2 FAILED in each of
     the two files.
  4. `opts.get("maintenance_charge_w", 2500)` restored in main.py: 1 FAILED,
     naming the file and the literal it found.
  5. `maintenance_hold_min` deleted from config.yaml's options block: 3 FAILED.

Full suite 17/17 in goodwe-addon-ci, twice, once under parallel load.

Stale prose that asserted the now-closed divergence as current is corrected in
app/watchdog.py, test_watchdog.py and test_peakguard.py - watchdog.py's example
still uses 1500 W, but because the point of the example is a charge strictly
inside the ceiling, not because 2500 is what ships.

adminandClaude Opus 5 182102eeaf SAFETY-25: say what peak_soc_floor bounds, and measure what it does not
checks / unit (pull_request) Successful in 3m41s
peak_soc_floor reads like a pack-wide reserve and is not one. The
grid-following loop has no SoC guard of any kind, so on a sustained-load
evening it discharges straight past that number and keeps going until the
pack's own BMS cut-out stops it.

The gap has now been written down four times without being filed -
SAFETY-18's finding (freeze.py:18), SAFETY-24's module note, its PR body,
and its honestly-uncaught 13th mutation - and never once measured. It is
measured here, on the committed 2026-08-20 capture, driving the SHIPPED
control.compute(), peakguard.decide(), peakguard.claim() and the real
arbiter.resolve() in main.py's order:

    19:00-22:00 UTC, 830 W mean, minimum 701 W, zero export in the window
    reference pack (300 Ah x 51.2 V x DoD 90) started at 21 %, one point
    above peak_soc_floor

      ends at 10.0 %  -  the bms_soc_floor cut-out
      1525 Wh delivered by the LOOP over 587 cycles
      549 cycles below peak_soc_floor, 343 of them still discharging
      0 cycles on which the peak guard filed any floor at all

AND IT IS A BEHAVIOUR, NOT A CONFIG VALUE. The same evening ends at
9.9715 % at peak_soc_floor = 5, 11, 20 and 60 - the shipped value and both
ends of the schema range - identical to four decimal places. The option an
operator would reach for cannot move the number by any amount at all. On
the same day's high-load block the two states coexist: 49 cycles reporting
PEAK GUARD FLOOR-LIMITED and, on all 49 of them, the arbiter simultaneously
granting the loop up to 2000 W of discharge.

WHY SAFETY-24 COULD NOT CLOSE IT. The peak guard files a `lo` limit - a
LOWER bound on the setpoint. That asymmetry is exactly what makes it
trustworthy: a reviewer proved across 19,800 combinations that it can never
lower a target, cap a discharge or contradict the arbiter. The same property
makes it structurally incapable of stopping a discharge the loop itself
wants. A floor on the guard cannot become a floor on the pack by being
raised, and the sweep above is that sentence measured.

WHAT THIS COMMIT CHANGES IS THE HONESTY, on the four surfaces an operator
actually reads. That half is required whichever way the open question is
answered, and it is the real misstatement on the live system today:

  * config.yaml, beside the option itself - it BOUNDS THE PEAK GUARD ONLY
    and is NOT A PACK-WIDE RESERVE, with the replayed evening and the sweep;
  * DOCS.md, in the options table and in a new section carrying the figures;
  * the STATUS-PAGE ROW for a floor-limited guard. This is the one line a
    human reads at the moment the guard stops discharging, and read alone it
    says "the battery is being held at peak_soc_floor" - which the replay
    shows is false in every cycle that row is rendered;
  * the PERSISTENT NOTIFICATION, which outlives the page. It now names what
    has stopped (the guard buying a lower bill) and what has not (the pack
    being spent).

peakguard.py and freeze.py carry the measurement beside the findings they
already recorded, so the next reader does not have to take the caveat on
trust.

THE PRODUCT DECISION IS NOT TAKEN HERE, and must not be. Whether the loop
gets a reserve floor of its own decides whether this house's battery may
discharge to the BMS floor on a heavy evening; that moves real energy and it
is the owner's call. DECISIONS/SAFETY-25-loop-soc-floor.md is the memo AC 1
asks for: the options, what each costs, what each protects, weighed against
MAINT-01 (a pack repeatedly at the BMS floor is the SoC-drift condition the
maintenance cycle exists to correct, and an over-tight reserve fights it from
the other side) and against the fact that this would be the FIFTH SoC key -
OPT-04's arbitrage_soc_floor fired SAFETY-24's "revisit if a third floor
appears" trigger unremarked, so SAFETY-27's naming decision should land
first. It carries a recommendation and says plainly that it is not a
decision.

It also records a trap found while writing it, and now CHECKED through the
real arbiter rather than described: the obvious shape of a loop-side floor
is a `hi` limit at P_LOOP, and filed while the peak guard is asking for a
positive floor that is `lo > hi` - which arbiter.py resolves to a
CONTRADICTION at 0 W, the battery PARKED in the one quarter of the month
that sets the bill. It is the same crossing-limits hazard
shaping_suspended() already exists to avoid. The ordering
`bms_soc_floor < loop_soc_floor <= peak_soc_floor` removes it provably,
because wherever the reserve binds the guard is already floor-limited and
files lo = 0; both halves are run in part 10d.

test_peakguard.py part 10 is a TRIPWIRE, not a guarantee. It records a
defect and goes RED the day somebody builds a loop-side floor, so the
exposure cannot change size under a green suite and closing it has to be
deliberate. Part 11's mutation 13 stays honestly NOT CAUGHT - nothing
prevents the loop discharging past this floor - but it now reports a number
instead of a sentence.

Verified: 16/16 suites green in the CI image. Eight mutations, each against
a tree copied fresh with __pycache__ excluded and mounted :ro, so no .pyc
existed to go stale (MUTATION.md's structural immunity, the same one it
records for CI); byte deltas +61, -8, -465, -430, -1088, -46, file deleted,
and -95; none is +0 B. All eight go red on the named check:

  M1 peakguard.claim() also files hi=floor_w        -> 7 red, incl. 10c
  M2 control.compute() gain forced to 0             -> 6 red, incl. 10a/10b
  M3 scope sentence removed from the status row     -> 10e red
  M4 scope sentence removed from the notification   -> 10e red
  M5 scope paragraph removed from config.yaml       -> 10e red
  M6 scope bullet weakened in DOCS.md               -> 10e red
  M7 the decision memo deleted                      -> 10e red
  M8 arbiter clamps crossing limits instead of
     reporting a contradiction                      -> 5 red, incl. 10d

AC 2 is left explicitly OPEN, pending the owner's answer.

glenn schrooyenandClaude Opus 5 9234016419 Merge release/1.0 (OPT-04) into SAFETY-24, and fix one grader the merge broke
checks / unit (pull_request) Successful in 3m36s
OPT-04 landed after the previous rebase. Conflicts were CHANGELOG.md and one
IMPORT LINE in validate.py; both refusal blocks and both option sets survive
untouched, and DOCS.md, main.py and config.yaml auto-merged.

⚠️ AND THE MERGE BROKE A CHECK THAT NEITHER CARD COULD HAVE SEEN ALONE.
test_peakguard.py graded "the first `.decide(` call in main.py" and asserted
there was exactly one. That was true when SAFETY-24 was written; OPT-04 added
`arbitrage.decide(...)`, so the merged tree had two and the assertion failed.
It failed loudly rather than grading the wrong call - the guard did its job -
but it cannot ship red.

Fixed by selecting the call by QUALIFIED NAME (`peakguard.decide`) instead of
by position, and requiring exactly one of THAT. Other modules may now call
their own decide(); this grader can no longer be moved by one of them. Verified
still discriminating: a decoy `peakguard.decide` added to main.py turns it red
on 7 assertions, and the `maintenance_soc_floor` swap still turns it red on 6.

Also folded in the review's wording finding. An assertion read "a CONTROLLER
whose SoC entity does not answer hands decide() None" while driving no
Controller. The wiring property is stronger than the one claimed, and is now
asserted on the SERVICE CALL: a Controller with no SoC never reaches the guard
at all, because `inputs_ok` is False and cycle() stops at the safety claim
first - so a `float(soc or 100)` defaulting line above the call site cannot
disarm the floor. The original decide()-level check is kept, reworded to say
what it actually grades.

Full suite green on the merged tree: 15 files.

glenn schrooyenandClaude Opus 5 bdd7f18a54 OPT-04: charge cheap, discharge expensive - and only when it pays
checks / unit (pull_request) Successful in 3m16s
Four cards built the price stack and nothing traded on it. app/arbitrage.py is
§10.1's priority 3, and it consumes all four rather than re-deciding anything:
whether a trade is permitted at all, on which two hours, against which widened
threshold is TariffPlan.arbitrage()'s answer, and that answer cannot be
obtained without first saying whether the peak guard is holding. §9.1's "peak
shaving outranks arbitrage" is therefore honoured structurally - there is no
path to a spread that skips the question - and again in the arbiter, where
P_PEAK (50) clamps a claim filed at P_ARBITRAGE (30).

A guard that never ran is not a guard that is clear. On meter_source off the
peak guard is never evaluated; that third state is carried as None and refuses,
because charging at the rail creates the billed quantity while nothing measures
the quarter. validate.py refuses that configuration too, along with arbitrage
armed with no price source and a SoC floor at or above the ceiling.

§17: never export into a negative price. The guard is on the hour being sold
into, not on the spread - a day priced -0.30 .. -0.05 clears any threshold and
its dearest hour is still negative. Buying in a negative hour stays allowed.

resolve_tariff() may open an HTTPS connection and the tick feeds the ESP32
heartbeat, so the fetch runs in its own task at a 30 min cadence and the tick
reads an attribute and an age bound. test_arbitrage.py section 8 asserts that
structurally on the shipped AST: a fetch put back on cycle() is red.

AC4 is NOT met and is not restated - this repository holds no price history.
Section 7 replays a synthetic year and asserts the property that does not need
real prices: every executed round trip cleared its own widened requirement, and
zero discharges landed in the 522 negative-priced hours. At the shipped 0.10
EUR/kWh threshold a realistic Belgian day/night site does not trade at all.
Reported, not tuned: that number and FCST-03's widening factors are one product
decision and it is the owner's.

glenn schrooyenandClaude Opus 5 e709554857 SAFETY-24: an energy floor under the peak guard's forced discharge
checks / unit (pull_request) Successful in 3m29s
SAFETY-07 can command a discharge to hold a billed quarter down, and
nothing below it consulted the state of charge. On the 2026-08-20 replay
it asks for 878 Wh in a day. Relying on the BMS is not absurd - it is a
real floor and it works - but it is the pack's protection rather than the
operator's, and a month of aggressive quarters leaves the battery
repeatedly at that cut-out with no EMS-side record of why. The first
symptom is a pack never available when wanted, which is indistinguishable
from the SoC drift MAINT-01 exists to correct.

decide() now takes soc and soc_floor, both required and neither
defaulted, and discharge_permitted() is the one place the question is
answered. Above the floor nothing changes. At or below it the guard files
a 0 W floor instead of a sized one - one-directional, so charging stays
blocked and no discharge is capped - and reports floor_limited with the
reason it bound. It is not a trip: every stop in 11.2's table still
outranks the claim, and the floor is never negative, so 9.1's asymmetry
survives as a property of the object (0 negative floors over 1296 swept
combinations, SoC included).

The SoC is graded only after `wanted > 0` is established, so it is never
evaluated where it governs nothing. An unreadable SoC is floor-limited,
not a full battery - a full battery is exactly the value that would
disarm the floor, and this project shipped that defaulting once already.

Failing to shave is not silent: one notification per episode
(goodwe_peak_soc_floor), distinct from the saturation alarm because the
two ask for opposite operator actions, plus its own status row and an
action-log line.

Verified by replay. The 2026-08-20 capture is driven against a modelled
pack sized from the day's own measured appetite, so it genuinely
exhausts: without the floor it reaches the BMS cut-out and holds there
for 1227 guard cycles; with it the pack stops at 20.0 % and never touches
the BMS. The energy withheld equals the energy between the two floors to
within one cycle at the rail. The honest half is reported too - the worst
quarter goes 4338 W -> 5030 W, because a floor-limited guard shaves less
on purpose.

Two new options, mirrored once in peakguard.PEAK_OPTION_DEFAULTS
(TARIFF-02's pattern), imported by validate.py and main.py rather than
typed as literals and pinned to config.yaml by a check that reads the
file - so CFG-03 still tracks three places. validate.py rule 8 refuses
peak_soc_floor <= bms_soc_floor at startup, in CFG-01/MAINT-04's manner.
maintenance_soc_floor is deliberately not reused and not renamed: it is a
drain target, not a spend limit, and the rename is recorded as a decision
to revisit if a third floor appears.

Eleven mutations of the shipped source were run against the checks; all
eleven go red and there are no survivors.

glenn schrooyenandClaude Opus 5 303525cfc5 TARIFF-03: static day/night and fully-fixed tariffs, first-class
checks / unit (pull_request) Successful in 2m43s
§9.2 puts a large share of the Belgian installed base on a static profile, and
an EMS that only works under dynamic pricing is an EMS for a minority. A new
`static_profile` option describes a two-period day/night tariff - or a single
fixed price - and app/static_tariff.py turns it into the same canonical
{start, eur_per_kwh, provisional} series the fetched providers emit.

Not a sixth provider plugin, for two mechanical reasons. capabilities() is a
classmethod, so a plugin's PriceProduct is fixed when the class is written -
but §9.2 makes STATIC and FIXED two different products and which one a site is
on is a property of the operator's data; StaticProfile.product derives it from
the number of distinct prices. And the plugin framework exists to stop a
FETCHED figure being marked up twice, which a number typed as all-in cannot be.
So the profile sits where §11.4 already says it does - under the providers, as
the fallback. Configured product and feed-is-down are one generator differing
in one flag, so the degradation path cannot rot unused.

"No arbitrage" is a type. TariffPlan.arbitrage() returns a variant whose
ALLOWED arm carries the spread and the cheapest/dearest hours and whose REFUSED
arm carries a reason and nothing else - .spread_eur_kwh on a refusal raises
rather than answering 0.0, so an optimiser cannot compute a trade from one.
Four refusals, all derived: peak guard holding, no price data, plan
provisional, or the series is FLAT. The last is AC2: a fixed tariff disables
arbitrage by arithmetic, not by matching on an enum. peak_guard_active is a
required keyword argument, so §10.1's priority 2 over 3 cannot be skipped.

Time-window shifting reaches the one shiftable load that exists: main.py's
cheap-window flag falls back to the static profile, and the UI gained a Tariff
row. Cheap is STRICTLY below the seven-day mean - `<=` would call every hour of
a flat tariff cheap, and 48 h taken on a Friday is two-thirds weekend.

A profile must tile every day type exactly once, checked at startup; a gap is
refused with the range named rather than filled in. `22:00-07:00 mon-fri` does
not cover Saturday morning, and that trap is what the check catches.

validate.py rule 7's stated reason expired exactly as TARIFF-02 predicted: the
test_price.py section 12 tripwire went red naming static_tariff.py. The message
now says what is true instead, and the tripwire is re-aimed rather than removed
- consumer set pinned, expired phrase asserted gone. Rule 7 also grew a second
refusal for static_profile alongside the HA price pair, the same silent-loser
conflict and a live one.

CFG-03 is not widened: static_profile went into price.py's PRICE_OPTION_DEFAULTS
- the one in-code mirror pinned to config.yaml by a check - and the new module
carries no defaults dict of its own.

Measured on the two committed days of this house's real P1 meter. 2026-08-20
(Thursday): 15.220 kWh imported, 9.606 day / 5.614 night, EUR 4.7185 under
day/night vs EUR 4.6725 flat, shifting saves EUR 0.8069 = 9.606 kWh x the
0.0840 spread, derived twice. 2026-08-23 (Sunday): 0.728 kWh, all of it
night-priced, which is the weekend row proving itself. §17 names six Belgian
scenarios; this is the seventh, and it is two days rather than a season - the
file says so rather than implying an annual figure.

All 12 suites green. Eleven mutations of static_tariff.py were each caught by
at least one check.
