adminandClaude Opus 5.5 7b65a3e69a UX-08 review: tighter notification texts, and two meaning fixes
infra-pin / fresh (pull_request) Successful in 1s
checks / unit (pull_request) Successful in 8m48s
- not delivering: the body said control keeps running and then "start
  control"; clearing it takes stop then start, and it now says so.
- peak reserve: the "reserve not set" branch is really soc_floor None,
  i.e. an inverter's cut-out level missing; it now names that. The title
  is true on all three branches ("Battery stopped limiting the peak").
- no semicolon run-ons in bodies (STYLE.md + test); loop-bound, circulating,
  meter-frozen and multi-unit over-rating bodies rewritten to match.
- allowlist cap is now exact, so a shrink cannot leave room to regrow.
- DOCS names the settings behind "peak reserve" and "cut-out level";
  DECISIONS no longer states the HA anchor behaviour as fact.

glenn schrooyenandClaude Opus 5.5 50ccea3dd7 UX-08 phase 2a: short, plain notifications, and a ratchet for the rest
checks / unit (pull_request) Successful in 8m54s
infra-pin / fresh (pull_request) Successful in 1s
Every HA notification the add-on raises now has a title of at most 5
everyday words and a one-sentence body; a red alarm may use three so no
action is lost. The texts live in app/messages.py, the rule in STYLE.md,
and the detail that moved out in DOCS.md "Notifications", which each body
links to. No notification_id, trigger or cadence changed.

test_messages.py enforces the rule on every notification, fails any
notification worded outside app/messages.py, and ratchets the kinds not yet
rewritten (rows, banners, refusals, logs, options) through a shrinking
allowlist of 200. Six tests re-pinned from prose to meaning.

glenn schrooyenandClaude Opus 5.5 55a6d5dcdb SAFETY-40 review: integrator-bound WARNING gets its own notification id
checks / unit (pull_request) Successful in 8m46s
infra-pin / fresh (pull_request) Successful in 1s
A later anti-windup notice could replace a write-path BUG SIGNAL notice
under the shared goodwe_output_clamp id (escalation ignores the budget).
The WARNING now uses goodwe_integrator_bound and points to DOCS; the
cadence sentence in DOCS is corrected. Tests pin both ids (red on fd14569).

glenn schrooyenandClaude Opus 5.5 fd14569a71 SAFETY-40: the integrator bound is not a BUG SIGNAL; numbers from the clamp tick
checks / unit (pull_request) Successful in 8m47s
infra-pin / fresh (pull_request) Successful in 1s
The clamp alarm gave `i_clamped` (normal anti-windup) the over-rating BUG
SIGNAL text, printed `Decision.i_w` as "the loop asked for", and printed
`self.target` (after slew/freeze) as "was clamped to".

- clamp.loop_clamp_note(): i_clamped says "the loop's integrator reached its
  N W anti-windup bound" with this tick's command; clamped keeps BUG SIGNAL
  with the requested command and the clamp's own result.
- Decision carries i_bound_w / requested_w / clamped_w, set at the clamp.
- i_clamped still counts and notifies (same id, cadence, SAFETY-41
  escalation) but as a WARNING, amber row, plain title. A bug has its own
  notification budget and its text is not overwritten within an episode.
- test_clamp.py part 9: red on the old code per defect; 5 mutations killed.
- DOCS.md alarm section (and its stale 30 s cadence), DECISIONS/SAFETY-40.

glenn schrooyenandClaude Opus 5.5 6028e21298 SAFETY-34: re-assert latched alarms, because a Core restart keeps the add-on
checks / unit (pull_request) Successful in 8m55s
infra-pin / fresh (pull_request) Successful in 1s
A Core-only restart wipes persistent_notification and does NOT restart the
add-on (measured on TEST-23: the add-on's SAFETY-31 card was gone 4 min after
`docker restart test23-ha`, add-on StartedAt unchanged). The latched SAFETY-31
and SAFETY-42 cards were re-raised only on add-on start, so they stayed gone.

They are now re-asserted every REANNOUNCE_S = 300 s while tripped (same
notification_id, so it replaces). test_watchdog part 6 and test_delivery part
8b grade it with the same process across the "restart"; red on the old code.
The docstrings that said the add-on restarts with HA are corrected.
Record: goodwe docs/DECISIONS.md, SAFETY-34 D4.

A missing or comment-only .gitea/infra-pin now ends on the workflow's own
FAIL line instead of git's `fatal: path ... does not exist` (still red). Every
x-access-token remote URL becomes an env-set Authorization header, so no

infra-pin / fresh (pull_request) Failing after 1s
checks / unit (pull_request) Failing after 2s
- .gitea/infra-pin: the one place the admin/goodwe commit is pinned.
- checks.yml: checks out admin/goodwe at the pin as the sibling test_freeze.py
  looks for; any failure fails the job. Tests run with GOODWE_REQUIRE_HWSIM=1,
  and `CI: ` lines are echoed on PASS so the log shows which transport ran.
- test_freeze.py: GOODWE_REQUIRE_HWSIM refuses the stub; a local stub run
  prints a STUB USED line.
- infra-pin.yml: a separate, non-required check that goes red naming both
  SHAs when admin/goodwe master has moved past the pin.

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).

glenn schrooyenandClaude Opus 5.5 71d2d4a37a SAFETY-61: the control task's death ends the process, after the wind-down
checks / unit (pull_request) Successful in 8m22s
A done-callback on run_control()'s task logs the traceback at the death and
sets `stop`; amain() runs the ordinary wind-down (shutdown() ->
command_site_zero()) and main() exits 70 (EX_SOFTWARE). Normal stops and
run_control()'s refusal path are ignored by the callback (still 0 / 78).

hass.py: a malformed JSON body, a JSON non-object, and an undecodable error
body are an absence / a failed write, not an exception into the loop.

checks() gains a first "control loop" row, red past FIRMWARE_INGEST_VETO_S.

Why exit rather than restart in-process, and what the Supervisor actually
does on exit (restarts only with the per-install Watchdog toggle on, default
off): DECISIONS/SAFETY-61-control-task-death.md.

predeploy_check.py and rehearse_roster.py now assert a positive property of
their input (a JSON object, most of whose top-level keys are known option or

--raw-json` wrapper, a truncated or list-wrapped state file and a wrapped
config no longer produce "CLEARED" / "NO FINDINGS" with exit 0.

Also: a clean --no-live-entities rehearsal exits 3, not 0; alloc_sim.py
exits 1 when split-invariance FAILS; decode_bus_capture.py takes several
paths and exits 1 on a file that is mostly not frames.

Graded by the new test_tool_inputs.py; DOCS.md says to pass .data.options.

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.

Self-review. The note added to `### SAFETY-57` said the reading rule it is
qualifying is "two paragraphs up"; it is in the paragraph directly above - the
same one the note follows. A changelog that misdirects a reader to a paragraph
that is not there is the small end of exactly the defect this cut is fixing
three sentences of elsewhere, so it is corrected rather than left.

Text only, one line pair, still two files in the branch's diff.

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:

    control   release/1.0 unset  846a10a5b89e321086d535825925721e2f791012e8405948d4fd38d3f9d0be5f

    control   TEL-11      set    846a10a5b89e321086d535825925721e2f791012e8405948d4fd38d3f9d0be5f

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.

adminandClaude Opus 5 8a6acd9fa2 SAFETY-56: the gate cannot tell a dead register from a pack that cannot comply, so stop saying it can
checks / unit (pull_request) Successful in 8m0s
Text only. No behaviour change - same conjunction, same limits, same MISSING,
same 0 W, same NOT READY. `tools/safety56_behaviour_trace.py` says so: 2390
capture reads, a 66-cell swept grid, and six driven controller worlds produce
the byte-identical document `6030175e...` on origin/release/1.0 and on this
branch, while the sentences differ.

THE DEFECT. SAFETY-37's conjunction is satisfied by two disjoint worlds - the
register has stopped reporting reality, or the SOURCE cannot comply with the
command - and nothing `freshness.py` is handed separates them. Three sentences
asserted the first. On the live 2026-09-21 episode it was the second: the pack
read 11 % for the whole 850 s hold, every command in that hold was a discharge,
and the register answered the first CHARGE command three seconds later. The
readiness row was worse still, because it asserted a false fact about a NAMED
entity that was present, numeric and updating - so the operator opened
Developer Tools, found it working, and had every reason to conclude the
diagnostics were broken.

THE FIX. Each message states what was OBSERVED and names BOTH explanations.
Three wordings, no shared helper: two are a log line about a behaviour, the
third is a banner about an entity, and a helper serving both would drop
whichever half the other caller does not need. SoC stays STATED, NOT WIRED -
part 11b drives the two worlds at 50 % and 11 % and the sentence does not move
one byte. The row does not branch on `batt_fresh.stale` either: `stale_note()`
already rides `liveness_notes()` a few rows below, so the discriminator is "is
that row there?", and part 11d asserts it is present in one world and absent in
the other.

THE CHECKS. test_freshness.py part 11 builds the pair of worlds with ground
truth written down rather than derived from the published stream, asserts they
are really two (40 of 40 reads differ) while the published stream is
bit-identical, and only then grades the sentences. Eleven mutations, all red:
each of the three sentences reverted (3, 2 and 2 named reds), the two
explanations transposed at ZERO bytes (1), the second explanation deleted (1),
the admission of ambiguity replaced by a ranking (1), all three reverted at
once (5), and two aimed at this card's own check - collapsing the world pair
(2) and emptying the accusation list, which a positive control against the
three sentences as 0.10.1 shipped them catches (1).

AND TWO OF THE ELEVEN FOUND DEFECTS IN THE CHECK RATHER THAN IN THE CODE.
Transposing `label` and `entity` in the row made it unfindable and the run died
on an IndexError - a red with no name and every later check ungraded, FCST-06's
shape exactly; `_s56_row()` returns a named absence now, 0 named reds before, 3
after. And the first invariance run compared a tree with itself, because it
archived a branch whose edits were not committed yet; the tool now REFUSES to
report "behaviour unchanged" unless the sentences halves differ, and both of
its refusals are driven.

SAFETY-57's part 10h check was the handoff and is inverted rather than deleted:
it required the accusation to still be present so that removing it had to be a
deliberate act. This is that act. Its escape clause is untouched.

Suite: 30/30 in the CI image, checks.yml's exact command, purged tree, :ro.

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 43c144b8d9 SAFETY-57: the stale-reading verdict gets an exit, because its own consequence is what stopped it being tested
checks / unit (pull_request) Successful in 7m58s
SAFETY-37's freshness gate reports a battery-power register as MISSING when it
stops following its own command, and a missing input is "command 0 W and keep
commanding" (§11.1 rule 1). The gate's only exit was "an arrival carrying a
DIFFERENT number" - and at 0 W nothing is asking the register to be anywhere.
The state had no exit reachable from inside it, and the log line promised the
opposite in the same sentence that announced the 0 W.

REPRODUCED FROM THE WIRE, NOT MODELLED. scenarios/safety57-2026-09-21/ is 3840
verbatim frames off the RS-485 pair, read from the passive sniffer, decoded by
tools/decode_bus_capture.py (0 unparsed, 0 bad CRC, 0 unknown shapes; the
mode->sign convention is graded off the capture, not trusted). The box was
running 0.10.0, so the 0 W in the trace IS the add-on's own claim:

  10:51:24.7  0x0518 reaches -3 W. Pack at 11 %, the BMS refuses the discharge,
              the inverter idles. THE REGISTER IS HEALTHY AND TRUTHFUL.
  10:51:29.7  the command reaches +1060 W - 800 W of travel
  10:52:00    the conjunction arms. Inverter.batt becomes None
  10:52:21.7  the site commands 0 W, on the wire
  ...         0x0518 does not change value for 850.0 s. The setpoint does not
              change value for 790.0 s. The house exports 2.4 kW throughout
  ~11:04      a human restarts the add-on. That is what ends it

AND IT HAD BEEN ESCAPING BY LUCK. Replaying the committed 16-day loop capture
through the shipped conjunction finds 93 trips whose wait for the BMS
keep-alive pulse that cleared them has a median of 143.4 s, a worst case of
21440.1 s, and 17 of 93 at or beyond this episode's 710 s. That distribution
belongs to the battery's firmware, not to this code.

THE CARD'S OPTION 2 ALREADY HELD AND IS NOT THE BUG. _grade() has required
|standing| >= MOVE_W since SAFETY-37. The trip was at +1060 W and the stuck
state is at 0 W; they are different moments, and an entry-side rule cannot
reach a state entered legitimately and then persisted. Nothing in the
conjunction is weakened here.

THE RULE, SAFETY-13's SHAPE ONE MODULE OVER - which latches get an exit, not
how long the block lasts:

  the verdict is withdrawn when the obligation that produced it has been gone
  for RELEASE_S, and the register is then re-graded from scratch.

RELEASE_S is BATT_OBLIGED_S, 17.0 s - the obligation window already derived in
the file (6.0 plant + 10.0 publish + 1.0 read), taken at the FLOOR of its band
for the mirror of MOVE_W's reason. Which half is safe is the opposite of
SAFETY-13's: being wrong long is the failure being fixed, being wrong short
costs one bounded re-grading window. Below 17 s the release pre-empts the
cheaper exit - the register answering by itself - and that is graded
behaviourally, not asserted.

The whole parked interval is now stale_input_s + RELEASE_S = 32 s. On the live
episode: telemetry back at 10:52:39 instead of 11:05:35, with 0x0518 still
answering the same -3 W. RED BEFORE (release_s=inf, a graded counterfactual and
not a second implementation), GREEN AFTER.

WHAT IT COSTS, AND IT IS NOT SMALL. A register dead for good is re-graded for
ever: over 1201 reads the held number reaches a consumer on 630 (52.5 %)
against 35 (2.9 %) before. Payable only because one window is at most 35 s and
the two consumers hold for 75 s and 85 s, so neither can reach a verdict inside
one and the re-trip clears both windows. No detection SAFETY-37 had is given
back - a permanent None clears the same windows for ever too - and the command
is derived from the P1 meter, never from batt.

Two clocks, deliberately: changed_mono/unchanged_s() stay facts about the
REGISTER, graded_from/graded_s() are the VERDICT's window. Collapsing them
either lies to the operator or defeats the re-grading.

main.py's stale line had its ESCAPE CLAUSE corrected - it promised a clearance
the state could not produce - and gained a STALE WITHDRAWN edge that says in
its own words that nothing has been learned about the register. The DIAGNOSIS
half is SAFETY-56's and is deliberately untouched, with a named check asserting
it is still there so that rewrite has to be deliberate.

Battery: 22 mutations, 21 red, 1 argued equivalent, 0 unexplained survivors.
Two findings kept in DECISIONS: _release()'s move_w test swapped for
unchanged_s SURVIVED at +5 B because every fixture rested at exactly 0 W (habit
11, closed by a 0/100/300 W fixture); and the code shipped a habit-22 comment
claiming the _release/_grade order was load-bearing, which the battery
falsified - the two act on mutually exclusive predicates, so the order is not
observable. MUTATION.md gains habit 23 for a mutation that ran, fingerprinted
clean, and was a no-op on the fixture because `0.0 or x` is x.

Suite: 30/30 in the CI image, checks.yml's exact command, purged tree, :ro, one
file at a time.

adminandClaude Opus 5 5aba220046 PKG-15: fold TEL-10 and SAFETY-48 into 0.10.0, so the version names its contents
checks / unit (pull_request) Successful in 7m53s
0.10.0 was cut by PKG-14 on 2026-09-16 and three tickets have merged into
release/1.0 since. Two of them change the built image - one is a CONTROL LAW
change and one adds three MQTT entities - and neither is described anywhere in
this file. Tagging that tree today would stamp a number on contents the
changelog does not account for.

FOLDED RATHER THAN CUT AS 0.11.0, AND THE ARGUMENT IS CONDITIONAL.
0.10.0 has never been built or pulled anywhere: the reference install is on
0.7.0 (PKG-14's own predeploy run records `deployed on the box : 0.7.0`), the
repository carries exactly one tag, `v0.2.1`, and no release. So the string
`0.10.0` does not yet name a tree anyone is running, and the PKG-06/PKG-07
no-op that forbade re-cutting `0.9.0` does not reach it. Cutting 0.11.0 would
burn a number on a release that never left the repository. The condition is
checkable and the section now says so: run against a box already reporting
0.10.0, `tools/predeploy_check.py` refuses with THE DEPLOY WOULD BE A NO-OP and
names the runtime commits since the bump. `config.yaml` stays at 0.10.0, so
`test_version_gate.py` 11b still finds the two sides equal.

SAFETY-48 IS THE ENTRY THAT MATTERED MOST TO GET RIGHT, AND WHAT IT PROMISES
IS LESS EXPORT - NOT A LOWER BILL. The measured result is export 39.61 -> 34.07
kWh over the committed 16-day replay, 14 % of the replayed figure, falling at
every plant and tuning variant swept (~4 % to ~16 %, median near an eighth).
The section says in its own heading and its first line that the control law
changed, and it says PLAINLY that the billed quarter is not a claim: at every
plant lag <= 5.0 s - including the one that best reproduces the recorded export
- release/1.0's worst quarter is ALREADY 3434 W and this changes it by exactly
zero. The 3739 -> 3434 W headline exists at the single longest fitted lag, and
the lag is not identified by the recording. The costs are in the entry too: the
cap moves a saturation-frozen integrator on 1095 of 79 160 frozen ticks, 679 of
them outward; SAFETY-13's settle values moved; SAFETY-39's "the slew does not
own the over-absorption" is now false.

TEL-10 gets the three site rows, what each one is, and the two things a reader
would otherwise get wrong: the lead is NOT a subtraction of two published rows,
and `Loop reason` is not the `Why` row. It repeats neither of the two sentences
TEL-10's own review retracted - EIGHT messages stay first and the ninth,
`goodwe_ctl/availability`, is byte-identical but deliberately moves to last.

CI-9 IS DELIBERATELY NOT IN THIS FILE, AND THE OMISSION IS WRITTEN DOWN RATHER
THAN SILENT. It changes one file, `.gitea/workflows/checks.yml`, outside
`goodwe_controller/` entirely: not in the built image, not in `is_runtime()`'s
list, and not observable on any version of the add-on. This file is the release
note the Supervisor shows beside the version number, and a row here has to be
something the person deciding whether to press Update could act on. The note
above SAFETY-48 says so and says the rule is about audience, not importance.

THE STRAY `## Unreleased` AT LINE 1777 IS NOT TOUCHED, AND THAT IS A DECISION.
It is the 0.8.0-era block PKG-14 annotated: every row in it has shipped, the
annotation says which release each went to, and re-filing it is PKG-08's card.
It is also load-bearing - `test_version_gate.py` 11d pins the count of
`## Unreleased` blocks below the newest section at EXACTLY one, so deleting it
is red on the commit that does it, and so is adding a second.

TWO MEASURED FIGURES IN PKG-14'S PROSE WENT STALE AND ARE RE-DERIVED, NOT
ADJUSTED. The runtime-commit count since `86bdf49` is now 32, not 28, of which
the contents table accounts for 24, not 21; both re-run through
`predeploy_check.is_runtime()` itself. The other eight are the three misfiled
tickets (SAFETY-43 x2, SAFETY-44 x3, TEST-21 x2) and `cb3f686`, PKG-14's own
bump, which edits `config.yaml` and so counts as runtime - it was HEAD when
PKG-14 measured and is inside the range now.

PKG-14's `CLEARED, exit 0` predeploy transcript was NOT re-run and now carries
the check that says why it still holds: `config.yaml` is untouched by both
tickets; `app/validate.py` imports neither `main` nor `mqtt`, and the three
names it takes from `control` - SLEW_RAIL_FRAC, LOOP_TICK_S, PLANT_SETTLE_S -
are byte-identical across cb3f686..HEAD.

Verified: the full suite in the CI image, `cp -a` of the tree, purged, `:ro`
mount, one file at a time, exactly the command in .gitea/workflows/checks.yml -
30/30, exit 0. No runtime file is in this diff.

checks / unit (pull_request) Successful in 7m55s
Four review findings, none of them in executable code. The control law, the
tests and the instruments' arithmetic are untouched; every number below was
re-measured against the committed 16-day capture before it was written down.

R1 - app/control.py carried a justification the decision record and MUTATION.md
habit 22 had already retracted, and it was false about the code it sits in. It
said an unconditional placement "would also pull the integrator toward a
command the SATURATION freeze is pinning", priced at 118 of 256 250 ticks. The
118 was measured against a different pair; on the pair the sentence names the
two forms are bit-identical - 0 of 256 246 ticks, re-measured. And the narrow
form that shipped DOES move a saturation-frozen integrator: it runs before the
freeze block and is not gated on `frozen`. Of 79 160 frozen ticks the cap
changes `i_w` on 1095, and on 679 of those it moves it further out on the side
it was already on - putting back magnitude the freeze had just let fall, which
the freeze's own rule forbids. Worst case 2424 W, at prev_w -3400 W, grid
+4697 W, actual -4144 W, sat_count 2 -> 3: the freeze leaves the integrator at
-176 W and the cap drags it to -2600 W. It never overrides a same-cycle refusal
(the freeze clipped on 75 512 ticks, the slew bound on none of them), and that
is stated too. It is also where SAFETY-13's settle values went: gating the cap
on `not frozen` puts test_control.py part 5 back at -1190 W exactly, while part
4(b) does not come back - that one moved for the winding reason.

R3 - the record read its own sensitivity table backwards. `fit_plant()` picks
lag 7.5 s on battery-power RMS, which separates it from 2.5 s by 0.3 %, while
the tool's own printed fidelity measure (export against the recorded 29.43 kWh)
prefers 2.5 s by the whole 35 % gap. Swept properly: at every lag <= 5.0 s
release/1.0's worst quarter is ALREADY 3434 W and this card changes it by
exactly zero. The 3739 -> 3434 W headline exists at one plant. New section 3a
carries the table; the export reduction now leads every summary and the peak is
presented as lag-dependent. The form-A rejection is strengthened rather than
weakened: form A is worse on the billed quarter at every lag where release/1.0
produces a peak at all, and at every top-N cut of the quarters.

R2 - DOCS.md stated modelled watts to the owner as measurement. It now leads
with the export reduction, says the figures are simulated, and says plainly
that no capacity-tariff improvement is promised.

R4 - tools/slew_sim.py --slew narrated "the OVER-ABSORPTION does not move, and
at the slowest slews it is slightly WORSE" while printing a monotonically
falling column. That sentence is TRUE on release/1.0 (reproduced:
958/1107/1133/1058/987/1029/1150/1143/1081) and false under this branch's law
(777/734/663/563/553/507/435/358/321), so SAFETY-39 is not retracted: its
record gets a forward reference, and the script now reads SLEW_LEAD_STEPS out
of the law it imported and narrates from the column it just printed. Both
branches of that narration were driven.

R5 - three counts in the L table were decoration and are re-driven in the CI
image on a `cp -a`, purged, `:ro`, one file at a time: L5 is 5+5 with the
function names exchanged and 5+4 with the branch bodies exchanged (two
mutations wearing one name, now listed separately), L6 is 6+3. The separable-
state count is grid-dependent and three sweeps disagree, so all three are
quoted with their grids and the load-bearing claim is WHERE they separate.

R7 - "a large import answered too weakly" is not what the aggregate shows. Form
A cuts import by 5.45 kWh and export by 5.18 kWh, and paired per tick delivers
8.56 kWh less offtake energy on the ticks release/1.0 was importing. The harm
is a tail redistribution inside quarters that already net to offtake. The
conclusion stands; the sentence is narrowed to it.

Verified: the full suite in the CI image, purged tree, `:ro` mount, one file at
a time, exactly the command in .gitea/workflows/checks.yml - 30/30, exit 0.

glenn schrooyenandClaude Opus 5 03ef61fa3b SAFETY-48: the slew step ceiling reaches the integrator, and what it bounds is the LEAD
`compute()` freezes the integrator with an asymmetric rule and the comment
beside it states the requirement outright - "the requirement is that the
INTEGRATOR stop accumulating, not only the command" - but `frozen` is computed
from ONE signal, `abs(prev_w - actual_w) > saturation_w`, and slew-limiting
never enters it. The integrator moves `gain * error` a cycle and the command
moves at most `slew_w`, so the integrator outruns the command whenever
`|error| > slew_w / gain`: 667 W at the live shape, against a measured median
grid error of 1114 W at the onset of a recorded episode. SAFETY-39's retune
made it MORE frequent, not less - a smaller step is a lower threshold.

⚠️ THE FORM THE CARD ASKED FOR RAISES THE BILLED QUANTITY, WHICH IS WHY IT IS
NOT WHAT SHIPPED. Reusing the asymmetric freeze on a carried slew flag was
built from release/1.0's own source and measured over 16.00 days / 256 252
meter instants of the live install's recorder: export 39.61 -> 34.43 kWh, and
the worst quarter-hour average OFFTAKE 3739 -> 3935 W with the mean quarter
+2.73 W, in five of six plant and tuning variants. A frozen integrator stops at
`prev + gain*error`, which undershoots by (1 - gain); for an export that is
free and for an import it is offtake, for as long as the ramp lasts. The card
said "do not invent a second rule"; the measurement says to, and both sentences
are recorded.

WHAT SHIPS BOUNDS THE LEAD AT ONE SLEW STEP, inside the branch where the slew
actually bound. Same 16 days, same ticks, same disturbance, same plant, same
seed: export 39.61 -> 34.07 kWh, wasted throughput 4.67 -> 3.19 kWh, battery
sign reversals 2992 -> 2770, median recovery 232 -> 199 s, p99 849 -> 850 s,
max 901 -> 898 s, unrecovered 53 -> 31, worst |i_w - prev_w| 9200 -> 800 W -
and the worst 15-minute average offtake 3739 -> 3434 W, i.e. the billed
quantity IMPROVES. `i_w = slewed` (a cap of zero) is better again at 32.02 kWh
and is refused: it is the velocity form this module's docstring says `i_w=None`
collapses to.

TWO COMMITTED NUMBERS MOVED, DELIBERATELY, WITH THE REASON BESIDE THEM.
SAFETY-13's released command settles at -800 W and -1200 W where release/1.0
settled at -1190 W and -2390 W, because there is less wound integrator to
settle onto; AC 4's property - it stops at the frozen integrator, not the rail
- is what is asserted and the second is now graded against `i_w` rather than a
literal. And SAFETY-39's "the slew does not own the over-absorption" is now
FALSE - INVERTED, on the independent first-order plant test_control.py writes
itself: 1005/1109/1285/1330 W rising with a slower slew becomes 729/550/424/326
falling. Two plant models that share nothing agree on the sign.

Evidence: `tools/replay_recorded_loop.py` plus the read-only capture it made
(scenarios/loop-2026-09-02_2026-09-17). The "before" law is the shipped file
with the block removed by a named substitution - never a transcription - and a
missing anchor is a REFUSAL carrying "NOTHING HAS BEEN MEASURED". The
instrument prints its own fidelity first: it reproduces 39.6 kWh of export
where the install exported 29.4, i.e. it is ~35 % pessimistic about the loop's
tracking, so only the delta is claimed.

30/30 suites green, including test_control.py's exhaustive i_w=None
equivalence sweep against the transcribed release/1.0 law, untouched: the cap
moves `i_w` and not `target`, and that sweep compares (target_w, sat_count,
frozen, reason).

Six law mutations, one instrument battery. L4 - the cap applied
unconditionally, -92 B - was a SURVIVOR of all thirty files: it is
bit-identical on the shipped configuration (0 of 256 246 ticks) and separable
on 2050 of 257 400 swept states, all at `integrator_max_w` above `max_w`, which
part 4 now drives. L5 and L6 are ZERO BYTES.

AND TWO COMMENTS IN THIS CARD WERE INVENTED AND ARE CORRECTED IN PLACE. The
one-sided spelling was justified by a two-sided form that would "drag a
trailing integrator" - it does not, and the two agree on 205 920 of 205 920
swept states; and a "118 of 256 252 ticks" figure had been measured against a
different pair. MUTATION.md gains habits 21 and 22 for both shapes.

NOT DEPLOYED, NOT VERSIONED. The live install still runs release/1.0's law.

glenn schrooyenandClaude Opus 5 b6c6da31d8 TEL-10: two sentences that named assertions this file does not make
checks / unit (pull_request) Successful in 7m57s
Both are review findings on the merged-in-spirit branch, and neither is in
executable code.

R6 - test_mqtt.py part 1's headline said "every one of release/1.0's NINE
messages is still byte-identical and still first". The assertion under it is
`announce(...)[:len(BASELINE) - 1] == BASELINE[:-1]`, which covers EIGHT: the
ninth, `goodwe_ctl/availability`, is byte-identical but deliberately moves to
last, so a prefix comparison cannot include it. Nothing was unguarded - the
`== SITE_NOW` on the next check pins it in its new position - but the sentence
was not the check. Part 3 carried the same mis-statement two lines from a check
that IS about all nine, and is corrected the same way.

R5 - M7's red count was decoration. Re-driven in the CI image on a `cp -a` of
the tree, purged, `:ro`, one file at a time, it is 10 reds in test_mqtt.py and
not 8, on this tree and on SAFETY-48's alike. The direction was right; the
number was inherited rather than re-measured, which is MUTATION.md's reporting
rule 3. A note beside the table now says that a red count is a property of the
SUITE as much as of the mutation and therefore has to name a tree.

Verified: the full suite in the CI image, purged tree, `:ro` mount, one file at
a time, exactly the command in .gitea/workflows/checks.yml - 30/30, exit 0.

glenn schrooyenandClaude Opus 5 b548525d10 TEL-10: the loop's integrator stops being invisible
`self.i_w` has been a separate quantity from the command since SAFETY-04 and
has left the process nowhere at all - no entity, no MQTT attribute, no log
line. The investigation behind SAFETY-48 could only RECONSTRUCT it from the
grid trace plus a replay; the reconstruction reproduced about a third of the
engagements it was checked against and was discarded, so the card it was
gathered for had to be argued from a measurement nobody could stand behind.
It could not have been made to work either: `i_w` depends on every cycle
before it, including the ones where the arbiter overrode the loop and
`main.py` re-seeded `self.i_w = self.target`, and that re-seed is invisible in
the grid trace.

THREE SITE ROWS, APPENDED AFTER release/1.0's EIGHT. `loop_i` is
`Decision.i_w` - the accumulator after the cycle, before the output clamp, the
slew limit and quantisation. `loop_lead` is `decision.i_w - prev_w` against the
command `compute()` was HANDED, which is not a subtraction of the other two
published rows: `Setpoint` is the arbiter's output and is this cycle's, so on
any cycle the arbiter overrode the loop the two differ - and that is exactly
the cycle on which the integrator was re-seeded. `loop_reason` is
`compute()`'s own word; the arbiter's `explain()` prints the winning claim's
NAME and has never carried the claim's reason, so `slew-limited` appears in
neither the `Why` row nor `Controller status`. Measured on the same cycle:
arbiter `'loop -> -5000 W'`, loop `'i-clamped'`.

NOTHING IN THE CONTROL PATH MOVED. `app/control.py` is not in this diff.
`compute()`, its returned `Decision` and every constant it reads are identical
to release/1.0, and all nine of release/1.0's retained discovery messages are
byte-identical and still FIRST in the announcement.

Evidence: 30/30 suites green in the CI image. Nine mutations, ONE survivor,
reported as one: `decision.i_w - self.target` for the lead is +2 B and green
because `cycle()` has not reassigned `self.target` at that line - the name is
kept for the coupling, not for a behaviour it buys, and M2b (+8 B) is the
mutation that does change the value and is red.

AND TWO OF THIS CARD'S OWN CHECKS COULD NOT REACH THE FAILURE THEY NAMED.
"the published integrator reaches its bound" was GREEN under the card's named
mutation (publish `prev_w`, -3 B), because the command reaches the bound too -
twelve cycles later. It asserts the LEAD TIME now and is red on 5. "a stopped
controller publishes not-running" was GREEN under deleting that branch's
assignments (-45 B, -67 B), because the fixture STARTED stopped and `__init__`
writes the same values; it stops the controller part-way through a run that
has already wound the integrator to -5000 W. Both are MUTATION.md habit 4,
found by the battery rather than by review.

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 a packaging decision this card does not get to take. The operator
account is in DOCS.md and the release note belongs to the next PKG ticket.

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
      section only, left below
  M4  a 4th retired provider in price.py   +62 B   RED 1 here, 4 in
                                                   test_price.py
  M5  `## 0.9.0` heading lost              -3 B    RED 1
  M6  a 2nd `## Unreleased` left standing  +27 B   RED 1
  M7  the slicer never closes              -32 B   RED 3
  M8  SUPERSEDED_TAXES... emptied          -5 B    RED 2 on the evidence

                                                   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.

glenn schrooyenandClaude Opus 5 e3ccd9f6ea SAFETY-47: what a shadow run can show, and the watts on its status row
checks / unit (pull_request) Successful in 7m48s
Not a leak and not a write-path defect. Shadow mode's safety is intact -
the substitution, the re-seed, the authorisation gate and the clamp are
untouched. What was wrong is what three merged documents SAY a shadow run
can show you, and a number on the status row that can be 6.61x what a live
controller would command.

SHADOW MODE CANNOT SURFACE A CLOSED-LOOP DEFECT, AND THE DOCUMENTS NOW SAY
SO. The battery is held at 0 W and the carried command is re-seeded to it,
so every measured input - the meter, the billed-quarter accumulator behind
it, the battery power, the SoC - describes a plant that did not respond. A
closed-loop defect is one whose stimulus IS that response. This is the same
property that makes shadow mode safe, so it is not a gap to close later:
the closed-loop answer comes from the closed-loop rig or from a live run.
SAFETY-10 §5 already conceded this for the grid-following loop. It was
never the loop leg's limitation; it is the general case.

THE "STRATEGIES ARE UNAFFECTED" EXEMPTION WAS TRUE UNTIL SAFETY-45 MERGED,
ONE COMMIT EARLIER. That card sizes the buy leg as min(asked, headroom)
with headroom = (900/remaining) x (ceiling - projected), and `projected`
reads the open quarter's accumulator - the meter - which is a function of
what the battery did earlier in that quarter. Measured on TEST-23 stage 3
at peak_cap_w 1500 / house 1200 / max_w 2000, one hour at 5 s:

  SAFETY-45's limit cycle  NOT visible. 28 onsets live vs 1; grid
                           -455.5..+3200.0 W vs flat at the 1200 W house;
                           guard engaged 410/720 cycles vs 0/720.
  SAFETY-46's SoC churn    NOT visible. The SoC moves 0.000000000 pp.
  TARIFF-14's wrong hour   VISIBLE, and it is the only one: which hour, at
                           what price, clearing what spread - identical on
                           720 of 720 charging cycles at a binding cap.

The exemption narrows to exactly what survives: WHICH hour a strategy picks
and WHY are unaffected; HOW HARD it trades is not. The peak guard's ceiling
and reasons are worth reading from a shadow run; its ENGAGEMENTS are not.

THE NUMBER IS CAVEATED, NOT RE-COMPUTED, AND THAT IS THE DECISION. The
arithmetic is not wrong - 900/remaining is correct for a meter genuinely
under the ceiling, and in shadow the meter genuinely is. It is the right
answer to a question nobody asked. Both surfaces now introduce the watts as
what would have been commanded ON THIS CYCLE, in every state, and carry
shadow.SIZED_FROM_METER whenever a measured billed quarter sized them.
Rejected, and recorded in the decision doc: re-computing it (the recorded
decision would no longer be the decision the shipped path reached, while the
arbiter, clamp, SAFETY-28 gate, log and MQTT all ran on the real one - a
second controller everywhere except the wire); recording nothing (blanks the
row exactly when arbitrage is trading, and the log's edge key is the watts);
and recording the unsized ask beside it (a second number, no warning, and at
the shipped 3500/2000 both figures read 2000 W).

"UPPER BOUND" AND NOT "SMALLER", AND THE DIFFERENCE WAS MEASURED. Charging
only adds offtake, so the shadow size is >= the live size with EQUALITY at
the start of every quarter. Pairwise over 3600 charging cycles in five
configurations: 0 below, 730 exactly equal. The first draft said "smaller",
which would have been false on every one of those 730.

AND THE PREDICATE IS NOT KEYED ON WHETHER THE TRADE WAS CAPPED. arbitrage's
own sentence says "SIZED BY THE CAPACITY-TARIFF GUARD" only when the
headroom came out below the ask - in a shadow run, the START of the quarter,
where the two runs agree to the float. By the end, 900/remaining has
multiplied the headroom past the ask, the trade is not capped, the sentence
is silent, and the record is at its most wrong. A caveat keyed on it would
be quietest exactly where it is needed loudest.

SAFETY-10 §6's COMMITTED EVIDENCE COULD NEVER HAVE FAILED, FOR TWO
INDEPENDENT REASONS, AND CLOSING EITHER ALONE CLOSES NOTHING. Its fixture is
peak_cap_w 15000 against a 350 W house, so the guard never engages and the
sizing is inert - the harness's own comment says so. AND every identity row
reads the FIRST charging sample, where at elapsed=0 the projection IS the
held level and the two runs agree to the float even at a cap that does bind.
Measured: widening the fixture alone leaves that comparison passing. That
second reason is a new shape for MUTATION.md's habit-4 list - an INDEX, not
a fixture - and it is recorded there as the twelfth instance. §6 is re-taken
at a binding cap across the whole run: 716 of 720 charging cycles differ,
headroom 300.0..54000.0 W in shadow against 299.9..307.8 W live, recorded
-2000.0 W against a live -302.4 W.

THE GRADER IS test_arbitrage.py PART 3d, beside SAFETY-45's own closed-loop
regression and built on the same s45_loop() harness, so the runs differ in
one argument. Three lines stand in for _write_unit()'s substitution and
_shadow_settle()'s record and re-seed, marked as a transcription;
test_clamp.py part 8 remains the check on the shipped placement. The section
carries its own precondition into every check: a mutation that stopped
either run trading made it raise on its first min(), kill the file and
report ZERO reds - FCST-06's shape, driven rather than imagined.

AND THE FIX'S OWN FIRST DRAFT CARRIED THE SAME DEFECT. Deleting the caveat
from the action-log line left all 29 files green, because the sentence was
an f-string inside _shadow_settle() and the only suite that drives it uses a
meter_source:off fixture where no arbitrage decision exists. It is
shadow.log_line() now, for the reason words() is a function.

14 mutations, no survivors; M13 and M14 are +0 B and were confirmed on disk
by sha256 with every run purged. M14's first form was aimed at the wrong
direction and correctly survived - min->max makes the shadow record larger,
which is still an upper bound. All 29 check files green.

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 e1b9254626 SAFETY-45: a price-driven charge is SIZED by the capacity guard, not switched by it
checks / unit (pull_request) Successful in 7m42s
With arbitrage armed at the shipped defaults, arbitrage and the capacity-tariff
guard drove each other in a sustained limit cycle. Re-measured on TEST-23 stage
3's closed rig against 478ba93, metrics recomputed rather than taken from the
card: `peak_cap_w` 1500 / 1200 W house -> 28 charge onsets an hour, mean period
131.1 s, the grid swinging -455.5 to +3200.0 W; at the SHIPPED
`peak_cap_w: 3500` with an 1800 W house -> 8/h, with a 3000 W house -> 32/h.
The bite rule is `load + max_w > peak_cap_w`, i.e. any house over 1500 W in the
cheapest quarter. §10.2: "an EMS that oscillates is worse than no EMS, both for
hardware wear and - per §9.1 - for the peak it is trying to avoid." And it was
losing the argument it was having: EVERY billed quarter in the three affected
configurations finished OVER the cap.

⚠️ THE CARD'S STATED MECHANISM IS WRONG AND THE CORRECTION IS ON THE RECORD.
The card, and .cache/s45.md before it, say the loop is the quarter boundary
resetting the projection and arbitrage re-arming at full power. It is not. Of
the 27 gaps between the 28 onsets, 23 are 90-120 s (mean 111.5 s) and lie
ENTIRELY INSIDE one quarter; the four long gaps - 230, 240, 250, 255 s - are
exactly the four that SPAN a boundary, so the boundary LENGTHENS the interval
rather than causing an onset. The real cycle, off the recorded fields: the trade
charges at max_w while `wanted = batt_w + excess` is negative and the guard
files NOTHING; `wanted` crosses zero; the guard engages on a floor of 5.3 W;
that flips `arbitrage.guard_state()`, which cancels the WHOLE trade; the
grid-following loop - which targets grid = 0, not grid = ceiling - takes the
actuator and discharges to +1870 W, exporting 420 W; the projection collapses;
the guard releases; the trade re-arms at max_w. A binary interlock keyed on a
continuous quantity. A fix aimed at the boundary would have removed four of
twenty-eight onsets.

THE FIX IS A SHAPE THIS ADD-ON ALREADY HAD. `control.maintenance_charge_floor()`
caps a MAINTENANCE charge at "the headroom left under the site's cap", because
"a maintenance charge is the only thing this system does that is big enough and
long enough to set that peak". ⚠️ That sentence stopped being true when OPT-04
landed. `peakguard.charge_headroom_w()` publishes the same quantity off the
MEASURED guard rather than off the optional `peak_forecast_entity` - the hole
SAFETY-25 had to close in `shaping_suspended()` - and `arbitrage.decide()` sizes
its BUY leg to it, keyword-only and with no default.

NO NEW ARITHMETIC AND NO NEW CONSTANT. The number is `wanted_w` read in the
other direction: `decide()` already computes the DISCHARGE that lands the
quarter on the ceiling, and a negative one is a permitted CHARGE of `-wanted`.
⚠️ `peakguard.decide()` IS UNCHANGED - sha256(decide) = 200090d0835a3a55, 7252 B
on this branch and on 478ba93 - so 2026-08-20's anti-bang-bang rung is exactly
where it was, and tools/replay_ac3.py reproduces 190/190 guarded quarters, 110
engaged cycles, 5 blind and 878 Wh on both trees.

TWO PROPERTIES MAKE IT SAFE TO HAND A STRATEGY, BOTH SWEPT RATHER THAN ARGUED.
It is INVARIANT IN THE BATTERY - raise the charge by dW, the meter rises by dW,
so `excess` rises by dW while `batt_w` falls by dW and `wanted` does not move:
1350.0 W at every point across batt_w -5000..+2000 W on one banked quarter,
while the `excess` those runs see takes six distinct values. It is feed-forward,
so consuming it adds no feedback path around the plant. And HOLDING IMPLIES ZERO
OR UNKNOWN: across 1080 swept combinations not one ENGAGED decision answers a
positive headroom.

AFTER, same rig, same command. 1500/1200: 28 onsets -> 1, grid swing 3655.5 ->
282.0 W, energy bought 180.0 -> 285.2 Wh (+58%, because a continuous 300 W trade
beats a 2000 W trade cancelled for 57% of the hour), billed quarters
1490/1497/1509 -> 1500.0/1500.0/1500.0. 3500/1800: 8 -> 1, 3511/3536/3559 ->
3500/3500/3500. 3500/3000: 32 -> 1, 3519/3542/3557 -> 3500/3500/3500. The two
shipped-default rows buy 2.2% and 1.6% LESS energy and in exchange the worst
quarter goes from 59 W over the cap to zero - which is the ordering §10.1 asks
for, since the capacity tariff bills the month's single worst quarter.
⚠️ AND THE NEGATIVE CONTROL: at peak_cap_w 5000 with a 1200 W house, where
`load + max_w` never reaches the cap, the two runs are BIT-IDENTICAL.

⚠️ A NEGATIVE `lo` WAS CONSIDERED AND REJECTED, AND THE REASON IS IN THE CODE.
Deleting `decide()`'s `wanted <= 0` gate and filing `lo = wanted` is the tidier
answer arithmetically. It creates a new `lo > hi` CONTRADICTION against
main.py's cheap-window maintenance shaping, which files a NEGATIVE `hi`;
arbiter.py clause 2 has no notion of one limit out-ranking another, so it
resolves to 0 W - the battery PARKED in the quarter that sets the bill - and the
only way to close that suspends the maintenance charge shaping PERMANENTLY on
every site this card is about. A backoff or cooldown in arbitrage was rejected
too: both modules' design notes say no timer is invented, and the trade now
re-arms at `ceiling - load` rather than at max_w, which is what learning from a
refusal means when the refusal is a measurement.

THE REGRESSION IS THE LOOP SETTLING, NOT A UNIT TEST ON decide().
test_arbitrage.py 3c closes the loop over the shipped guard, strategy, arbiter,
control law and QuarterAverager with a modelled plant, and asserts BOTH
directions: unsized it must run away (24 onsets, -414..+3200 W, a quarter over
the cap) and sized it must settle (1 onset, 303 W swing, three quarters at
exactly 1500.0 W). The two runs differ in one argument. A third pair asserts the
card is INERT where the defect is inert.

Evidence: 29/29 green. 14 mutations, every one RED on a named check, no
survivors; two are ZERO BYTES - `min()` -> `max()` on the sizing, and the
sized-trade sentence's two operands transposed - and both are red. M13 reverts
the 2026-08-20 rung and is red on EIGHT named checks in test_peakguard and three
in test_arbitrage. Every revert verified by a tree fingerprint AFTER the revert,
which is how a defect in the battery's own harness was found: two edits to one
file, restored in list order, left the first one on disk (MUTATION.md habit 18).
test_peakguard.py part 1 also gained a None-safe format, because the mutation it
exists to catch made it raise TypeError one line later and ABORT the file -
parts 2-13 were ungraded and M13's recorded coverage was one check instead of
eight.

Not fixed, and named: TEST-23 finding 1's export overshoot at the END of a trade
(356-938 W, ~0.37 x max_w) is a different card; a house whose load ALONE exceeds
the cap still has the trade refused outright and the loop drive to grid = 0
rather than to the ceiling, and no swept pair reaches that regime; the container
leg (hadrive.py) was not re-run because test23s3-addon is deliberately stopped
as a second writer on the setpoint entity.

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.

`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

                                               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.

glenn schrooyenandClaude Opus 5 2fac0aaf06 TARIFF-17: a price component that varies by hour has somewhere to live
checks / unit (pull_request) Successful in 7m25s
`price.py` modelled the whole non-energy part of a Belgian bill as ONE flat
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

adminandClaude Opus 5 610725bed9 TARIFF-11: the plan's account of itself, corrected and put on the page
Four defects of one shape - the add-on's report of its own tariff plan was
wrong, always in the direction that flattered it - and one check, which is
the deliverable.

1. `TariffPlan.words` counted POINTS and called them HOURS. The live add-on
   logged `dynamic_dayahead from generic_dayahead, 132 h` for 132
   quarter-hourly points = 33 hours. Belgium moved to a 15-minute MTU on
   2025-10-01, so this was wrong every time it was printed, and NOT by a
   constant factor: a 40-hour soak measured 1.79x .. 5.33x, because §8.3's
   carried points are hourly while the firm ones are quarter-hourly.
   `words` now reports both quantities, plus the firm/carried split and the
   spacing, in FCST-04's *Price history* wording so the two rows can be
   compared.

2. §8.3's firm-pair refusal and the flat-tariff refusal did the same, and
   they reach an operator through `self.arb.explain()`. This is exactly the
   point<->hour conflation TARIFF-14 removed from `at()`, left standing in
   the prose. `price_forecast.py`'s §8.3 carry-forward log line carried the
   third instance - a carried-HOUR count over a POINT count - and DOCS
   quotes it verbatim, so it is corrected here too.

3. The plan reached no HTTP surface at all. `rows["Tariff"]` was
   `static_status()`'s 30 s-tick sentence and never saw the provider plan -
   it read 'no static profile' at all 802 soak samples on a site whose feed
   was answering. It now carries the plan's shape. ⚠️ The two sources are
   kept distinguishable: the plan half is stamped with its own age, measured
   from `tariff_at`, because it can be up to TARIFF_MAX_AGE_S (5400 s) old.
   FCST-04 pins that row to DOCS as a pair; DOCS moves in this commit.

4. `main.py`'s "if and only if" was false. `cycle()` returns at the input
   hold before `self.arb = None`, so an armed site read
   `off (arbitrage_enabled)` - naming an option that is on - and, after one
   completed cycle, showed a decision up to 15 s stale as a current one. The
   row now reads the OPTION and separates three facts; `cycle_at` and
   `arb_at` make "this cycle reached no decision" an observation.

THE DELIVERABLE IS THE CHECK. All four survived 29 green suites because
nothing graded the strings a human is shown. `test_price.py` section 12
renders through the shipped `status_payload()`, parses each number out of
its OWN SLOT and compares it against a figure computed from the fixture's
construction parameters - not from the property the row was built out of
(habit 4), and not as a substring of a sentence the same file wrote (habit
14). The fixture set is four plan shapes and the check computes and prints
the field pairs no fixture separates. The *Arbitrage* row's states are
driven through real cycles with a sensor answering None and graded by
INEQUALITY.

No behaviour changed: no threshold, refusal rung, claim or setpoint moved.

MUTATIONS: 16, no survivors, one at +0 B (the risky delta) and red. Two were
found by the battery INSIDE THIS CARD'S OWN CHECK: a -190 B survivor whose
fixture varied two things at once (habit 4), and a mutation whose red was a
TRACEBACK in an f-string operand and therefore named nothing (FCST-06). Both
closed; the table is on the PR.

All 29 test files green.

glenn schrooyenandClaude Opus 5 a991438e40 TARIFF-13: the coverage figure beside the peak stops resetting at a restart
checks / unit (pull_request) Successful in 7m27s
The capacity-tariff status row printed a peak read from SQLite next to a count
of banked quarters read from PROCESS MEMORY - `PeakTracker.recorded`, an `int`
set to 0 in `__init__` and counted up inside `sync()`. A 40-hour soak caught
what that means at a driven restart, on both instances independently:

  before: 2026-09: peak 365 W, set by the quarter at 2026-09-11T18:45:00+00:00
          - 10 % of the 3500 W soft limit; 120 quarter(s) banked
  after : 2026-09: peak 365 W, set by the quarter at 2026-09-11T18:45:00+00:00
          - 10 % of the 3500 W soft limit;   0 quarter(s) banked

Reproduced here before anything changed, through the real Controller and a real
restart - a second Controller object against the same file on disk - at 12 -> 0
with 12 rows standing in `quarter_blocks`.

The peak is durable and was never wrong. The COUNT is what says how much of the
billing month that peak covers, and 365 W over 120 quarters and 365 W over 0
quarters are different claims about the same number. Mid-month, after every
restart, the page made the weaker claim while displaying the stronger one's
value. That is TARIFF-01's own argument - an unreadable store must not read as a
zero peak, because a zero peak is disarming - one column over.

`PeakStore.banked_count(month)` asks the database, and `recorded` is a property
over it. Two more defects in the same variable fell out once it was driven, and
neither was in the ticket: it was never scoped to a MONTH (on 1 October the row
still showed September's tally beside October's empty month - measured), and it
missed the block `restore()` banks from the checkpoint, which never passes
through `sync()`.

⚠️ NOT 0, AND NOT None, WHEN THE STORE WILL NOT ANSWER. `banked_count()` returns
None and the row renders `an unreadable number of quarter(s) banked`.
`f"{None} quarter(s) banked"` was rejected because it reads as the same zero.
`0 quarter(s) banked` stays true and reachable - it is what a month nothing has
been written to says, and the two are asserted to be different text.

⚠️ THE DEDUPE IS NOT REMOVED WITH THE COUNTER. `_seen` still stops `cycle()`'s
once-a-second `sync()` re-banking a block `P1Ingest.blocks` keeps for a day. The
check that graded it asserted `recorded == 1` - the dedupe and the figure
reporting it were the same variable - and now grades `sync()`'s RETURN, because
counting rows cannot see a re-bank at all (PRIMARY KEY no-op).

THE TIE RULE, DECIDED RATHER THAN EMERGENT: at equal wattage the EARLIEST
quarter keeps the attribution. No bill and no guard moves - `peak_w` is still
only ever raised, the `>` term is untouched, SAFETY-07 reads the same watts.
The two readers DID disagree: the upsert's strict `>` kept whichever tied block
was WRITTEN first while `recompute_month()` has always kept the earliest, the
same only while blocks arrive in time order, and measured to diverge (09:45
against 09:00) fed newest-first.

⚠️ AND THE SOAK'S DRIFTING QUARTER WAS NOT A TIE. Six exactly equal 365.0 W
quarters re-attributed zero times on the shipped tree - `>` is strict. What
moved it was a real new maximum BELOW THE ROW'S OWN RESOLUTION: the row renders
whole watts, so 365.0000001 W is a new peak to the database and the same 365 W
to the reader. Left alone deliberately, and pinned so it is not re-diagnosed.

test_tariff.py parts 11 and 12. 12 mutations, all red, listed on the PR; M2 -
`banked_count()`'s sqlite3.Error arm returning 0 - was a SURVIVOR at -3 B on the
first battery, because a handle that never opened short-circuits before any SQL
runs and nothing reached the except arm. Closed with an open store whose table
is dropped under it, with a precondition that the same call answered 4 first.

main.py is NOT touched - TARIFF-11 holds its status rows. The row picks this up
without editing because `recorded` is an attribute access and is now a property.
The residual is stated in DECISIONS §3: `recorded` answers for now() while the
peak follows `checks(when=...)`, and the shipped install has exactly one call
site - `self.checks()` with no argument, main.py:4359 - where they are the same
month, so the live page is correct and durable. `recorded_in(when)` is shipped
and the row's move onto it is one token, for whoever holds main.py next; part 10
pins the present behaviour against a row count taken from `quarter_blocks` so
the gap cannot be quietly forgotten.

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.

glenn schrooyenandClaude Opus 5 028c3e53fb Merge release/1.0 (TARIFF-12) into TARIFF-14
checks / unit (pull_request) Successful in 7m13s
Second base move while this card was open: 559f0eb -> a6e64fb. Only
CHANGELOG.md conflicted; test_arbitrage.py auto-merged (TARIFF-12 used
section 8b, this card uses 10, so the two do not collide).

CHANGELOG: both entries under the single ## Unreleased in MERGE ORDER -
TARIFF-12's row and section precede this branch's, because it landed
first. No version number is picked; PKG-06/07's note stands untouched.

WHAT TARIFF-12 CHANGES FOR THIS CARD - written out in decision note §8
rather than left silent, because the question is a fair one.

A served plan can now be up to TARIFF_MAX_AGE_S = 3 * TARIFF_REFRESH_S
= 5400 s old, where before it was at most one refresh interval, and
at() is what answers "what does it cost right now" out of that older
plan.

* PER-POINT SPAN: unaffected, structurally. Every window is derived
  from the neighbours' ABSOLUTE start instants - datetimes in a frozen
  dataclass in a tuple, which cannot move - and _cover_table() runs
  once at construction over data that cannot change. A plan's AGE is a
  property of fetched_at/tariff_at, never of a window. The index cannot
  go stale, which is a small positive under TARIFF-12: a kept plan now
  lives longer and there is nothing in it that needed recomputing.

* ONE-HOUR CAP: unaffected. It bites only at a hole; walking further
  into a series crosses more windows, each resolved on its own
  neighbours.

* THE TAIL: reachable for the first time, and §2's choice survives it.
  At the shipped 48 h horizon the tail is ~46.5 h beyond anything a
  90-minute-stale plan can be asked about. But price_horizon_h is
  int(1,72), so a 1 h horizon is a SUPPORTED configuration, and a
  90-minute serve-stale window against a 1 h series puts `now` past the
  end. Under the chosen rule a quarter-hourly 1 h series ends at :45,
  its window closes on the hour, at() raises Absence, _act() idles and
  §11.4 sends the site to the static profile. Under the REJECTED flat
  one-hour tail the same stale plan would have traded against the :45
  print for up to 45 minutes after the interval it describes had ended.
  So TARIFF-12 does not weaken the decision - it is the first thing
  that makes it reachable, and it selects the same answer. The rule
  should be re-read if TARIFF_MAX_AGE_S is ever widened again.

* TariffPlan.from_feed is a pure predicate on `origin` and TARIFF-12
  keeps or replaces a WHOLE PLAN OBJECT. It never splices two reads
  into one series, so it cannot hand at() an unsorted or duplicated
  point list.

RE-GRADED ON THIS BASE, not carried over: all 29 test files green;
app/price.py byte-identical to the TARIFF-10 merge (90d8ca31f7c0109d,
85953 B) because TARIFF-12 does not touch it; M1 re-driven at +68 B,
red on the same 24 named checks across both files; M3 re-driven at
ZERO BYTES, red on the same 4. Each purged before the run and reverted
with the fingerprint re-checked, from a card-specific harness at
/home/homelab/.cache/t14-mut/ with a mktemp backup inside it.

This branch contributes zero diff to app/main.py and app/static_tariff.py.

checks / unit (pull_request) Successful in 7m10s
CI on PR #80 was NOT a test failure. The workflow's "grade the merge, not
the branch" step refused the PR because it does not apply, and said so
itself: "REFUSED: refs/pull/80/head does not merge into release/1.0.
NOTHING HAS BEEN TESTED. This is not a test failure - no test ran."
Conflicts were CHANGELOG.md and test_price.py; app/price.py auto-merged.

CONFLICTS RESOLVED

* CHANGELOG.md - both entries belong under ## Unreleased. TARIFF-10's
  table row and section come first because it landed first. No version
  number is picked here; PKG-06/07's note stands untouched.

* test_price.py - BOTH cards appended a section "13". Nothing is
  dropped: TARIFF-10's stays 13, this card's is renumbered 14, and
  TARIFF-10's temp-directory teardown stays at the end of the file. The
  two share no fixture, option dict or helper name.

WHAT TARIFF-10 CHANGES FOR THIS CARD - nothing in the reasoning, and the
check is recorded rather than asserted (decision note §7).

In app/price.py the two do not meet: TARIFF-10 added provider_id() and
provider_configured() beside price_option() and routed load_prices()
through them - the option-reading layer, touching nothing in _Series,
at(), covers(), window() or _cover_table(). The merged at() is
byte-identical to the one the mutations were driven against.

Behaviourally TARIFF-10 makes run_tariff_refresh() run with arbitrage
OFF, so a provider-configured site now has a standing plan - and
therefore a _Series - where before it had none. It does NOT add an at()
consumer to the 30 s tick: static_status() builds a STATIC plan (hourly,
immune), main.py calls only plan.words on the fetched plan, and
price_forecast.price_permits()/begin_phase() have no caller in main.py
at all. So TARIFF-10 neither creates nor closes any exposure this card
is about - it enlarges the defect's reach the moment such a site arms
trading, which strengthens the fix without changing it.

RE-GRADED ON THE MERGED TREE, not carried over

* all 29 test files green;
* all EIGHT mutations re-driven, purged before each run, each reverted
  with the fingerprint re-checked. Same verdicts and same red-check
  counts as before the merge: M1 (the shipped one-hour scan, +68 B) red
  on 24 named checks across both files; M3 (the ZERO-BYTE tail rule) red
  on 4; M2/M4/M6 on 1 each, M5 on 2, M7 on 16, M8 on 14.
* Clean app/price.py on the merged tree: 90d8ca31f7c0109d, 85953 B.
* None of TARIFF-10's 650 new lines of checks moves under any of the
  eight - they grade resolve_tariff()'s reachability from a
  configuration, not the lookup.
