PRICE-02 round 2: require now, undo the test loosening, analyse ties
- TariffPlan.arbitrage(now=...) is required (keyword-only, no default); so are homeview.trade_verdict/refusal_key's now. Existing test calls pass one. - test_arbitrage.py: no module-level decide wrapper. Fixtures that probed a one-day plan after its extremes now hold two days (as a site does); the flap day gets a unique cheapest and dearest hour; the replay breaks its ties without direction. The flap bound is <= 4 and the replay check is len(_trades) < 365 again. 228 checks pass on the old and the new code. - test_price02.py part 6: ties (equal quarters, a real 15-minute day, alternating hourly prices) and the required now. - Identity pins: the masked digest is only for the older-tree comparison; this tree's own digests are pinned with nothing hidden. - DECISIONS: the tie analysis with numbers.

PRICE-01: price_service provider, fallback chain, and the gate read from it
A new price source, `price_provider: price_service`: the owner's price server,
one fixed HTTPS host, a bearer token (new password option
`price_service_token`), wholesale energy only so markup and taxes are added as
for generic_dayahead.
The chain is server, then energy-charts, then the prices the history store
kept. A step counts only if it has a price for now. Each step down and back up
is one log line. With every source down a site plans from what it saved.
No price for now: one status row, one Home plan line and one notification, in
English and Dutch, cleared when a price returns. With this provider the
maintenance charge gate reads the provider's prices and keeps the Home
Assistant rule: the current 15-minute price is at or below today's average.
The token is hidden on the settings page, refused when missing, and taken out
of any error text. Other providers, `off` and the Home Assistant pair take the
road they always took (scripted-day probe against

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

UX-10: the last plain-language leftovers: log lines, two table rows, 'Why: Other', red at 0 s
- test_messages.py part 6: every dynamic part of a WARNING+ line is classified as data or as a built text, and every built text is produced by the real code and checked. This is the gap the 2d scan had: it counted `%s` as one word, so reasons built by loop_clamp_note() and friends were never seen. - Quoted reasons rewritten to STYLE.md (red-alarm shape, codes kept): OUTPUT_CLAMP, METER_FROZEN, CIRCULATING_POWER, STALE_READING, the peak guard (codes now PEAK_GUARD*), the migration report, price feed, price history and gate reasons. Plurals via messages.times()/count(). - Top table: Price history "96 prices over 24 hours for 26 Sep", Tariff "one every 15 minutes or every hour", "not final yet" dropped. - Levels and noise: per-cycle shadow line DEBUG, shadow on/off INFO, aiohttp access log only at log level debug, settings warnings once per start, one plain line per Home Assistant outage (hass.Outage). - INFO jargon and error texts: no "§8.3", ISO times, "banked", "keys ARE", "NOT_OBSERVED", "did NOT land", "AND". - Display bugs: WHY_WINNER covers every winner and safety reason (main.why_key(), part 7 finds them in the code); the meter row is amber "waiting for the first reading" inside its limit after a start; the missing-reading age is counted when the page asks. - STYLE.md and DECISIONS/UX-08-short-notifications.md (UX-10 section). No change to safety behaviour, alarm levels, notification ids, triggers, cadence or the banner cascade. One row colour changes (meter at start), justified in DECISIONS.

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.

TARIFF-18: price_taxes_eur_kwh stops shipping at half the real figure
checks / unit (pull_request) Successful in 7m48s
`price_taxes_eur_kwh` shipped at 0.06 EUR/kWh with no recorded provenance -
no card, no date, no component list - and roughly HALF the true Flemish
all-in non-energy figure. It now ships at 0.11736, and the rows it is made
of are in the code rather than in this message:
Fluvius distribution (Antwerpen) 5,35 c EUR/kWh
Bijzondere accijns, "Alle verbruik" 4,876
Bijdrage groene stroom en WKK Vlaanderen 1,51
Energiebijdrage (0 EUR/MWh since 2026-08-01) 0
------
11,736 c EUR/kWh = 0.11736
Eneco residential card for Flanders, September 2026, incl. 6 % VAT.
`app/price.py`'s FLEMISH_TAXES_COMPONENTS_EUR_KWH carries the rows and
test_price.py section 1b re-adds them - and also compares the total against
the card's own figures typed in the test file, so an edit that moved the
rows and the default together is still caught.
WHAT THIS IS NOT. It is not an arbitrage-correctness fix and it cannot be.
This scalar is a LEVEL component: an additive constant cancels exactly in
`max - min` and leaves the argmin where it was. TARIFF-17 shipped that proof
and it is unchanged - test_price.py 16b drives six flat scalars spanning and
exceeding the whole per-DSO range and gets the identical cheapest hour and
the identical spread to the last digit. DOCS and the CHANGELOG say so in
those words.
WHAT IT IS. A display and guard fix:
* every number an operator reads, which at half the true value made the
add-on look considerably better than it is; and
* §17's negative-price guard in arbitrage.py - the one rung that tests an
ABSOLUTE all-in price rather than a difference. It fires when
`spot < -(markup + taxes)`, so its boundary moves -0.09 -> -0.14736
EUR/kWh of spot. test_arbitrage.py section 2c drives both sides through
the shipped decide() and pins the boundary from below as well.
The default is Antwerpen's real row, near the LOW end of the 0.117-0.131
per-DSO band, and that is deliberate: the error directions are not
symmetric. Too high carries a genuinely negative hour above zero and the
add-on exports into paid-for disposal - §17's own case. Too low only
declines a discharge that would have paid.
TARIFF-17's INTERACTION, WHICH HAD TO BE DECIDED. Nothing in that rung
hardcoded 0.06; it read PRICE_OPTION_DEFAULTS, so moving the default moves
what it refuses. The Supervisor sets `App.options = deepmerge(config.yaml
defaults, stored options)`, so a saved blob carries the key whether it was
typed or not - every stored 0.06 became "non-default" with nobody editing
anything, and a working Walloon or Brussels site with a taxes table would
have met SystemExit(78) on the upgrade over an inert number. price.py now
carries SUPERSEDED_TAXES_DEFAULTS_EUR_KWH = (0.06,) and validate.py reads a
superseded default as untouched too. The rung is NOT weakened: 0.1198 beside
a table is still refused by name, and the refusal now names both figures.
config.yaml and PRICE_OPTION_DEFAULTS moved together; CFG-03's tripwire
(test_price.py section 1, test_defaults_pin.py) stayed green by agreeing.
test_price.py section 0's fourth check was REWRITTEN rather than re-pointed:
it used to justify the file's own grading constants by observing that the
shipped pair was degenerate (0.06 is exactly twice 0.03). TARIFF-18 ends
that coincidence, so the sentence is no longer true and is not kept.
29/29 test files green. Mutation ledger on the PR.

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

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.

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.

FCST-05: one byte stops stopping the add-on, and the write path gets the read path's standard
checks / unit (pull_request) Successful in 7m10s
HIGH - a non-UTF-8 byte in /data/price_history.json stopped the add-on
from starting. `_load()` caught `(json.JSONDecodeError, OSError)`.
`UnicodeDecodeError` is `ValueError -> UnicodeError -> UnicodeDecodeError`:
neither of those, and `issubclass(UnicodeDecodeError, OSError)` is False. So
it escaped `_load()` -> `_open()` -> `PriceHistory.__init__`, which
`Controller.__init__` does not guard - breaking `_load()`'s own stated
contract, "a corrupt cache must not stop the controller". The handler now
names the ValueError FAMILY (the file's content) beside OSError (its bytes),
because a third subclass nobody has thought of is how this arrived the first
time. The suite could not see it: its "unreadable file" fixture writes
"{ this is not json", which is valid UTF-8 and fails one step later, in
`json`. A fixture holding a genuinely undecodable byte is now beside it,
with the difference between the two asserted as a precondition.
MEDIUM - a malformed `start` under the day the feed is writing to killed the
tariff plan permanently. `_remember()` merged with `{q["start"]: q ...}` and
sorted on `q["start"]`, trusting a value read off /data to be a hashable,
sortable string. An int, null, a dict or a list raised TypeError out of
`carry()` -> `resolve_tariff()` -> `run_tariff_refresh`, which catches
Exception - so the add-on stayed UP while every refresh raised forever, the
plan retiring after TARIFF_MAX_AGE_S with arbitrage and the cheap window off
for good, and no self-heal because `_remember()` raised before `_save()`.
The read path was properly defensive throughout, which is why `yesterday()`
survived and the existing fixture passed - it files its malformed rows under
a day the feed is NOT writing to. Both paths now share one validator,
`_point_of()`. A row that is not a point is dropped, reported, and written
back out clean.
...and the status row said the store was healthy while the plan was dead:
`words` read '2026-01-15 (1 h)'. `_load()` now counts the rows inside a kept
record as well as the record itself, so the store stops reporting plain
health from the moment it is opened; the note names what was FOUND at open
and what was DROPPED by the refresh, and clears once the file is rewritten.
...and the merge key is the validated INSTANT rather than its spelling,
which is what rule 4 already said. The lexicographic sort beside the string
key also put the second 02:00 of the 25-hour October day (+01:00) before the
first (+02:00); stored order only, since `_parse_points()` re-sorts.
LOW - the status row counted POINTS and printed them under the HOUR's name:
'2026-01-13 (96 h)' for a 24-hour day on the quarter-hourly feed this add-on
already supports. It is now '96 points over 24 h' - two facts, each under
its own unit.
LOW - two stated reasons were false. `_audit`'s "WHY IT IS STRICTER" claimed
the rework refused the same published point emitted twice and a carried
point sharing a published hour, "which the old count never looked at". A
differential over the whole domain the audit can express finds ZERO
divergence in both directions: the old `seen` count already refused the
first (one point twice is one hour twice) and the old IDENTITY rule already
refused the second. The reworked audit is EQUAL to FCST-03's, not stronger;
the only behavioural change is the intended relaxation, and it stays. The
differential is committed as a check rather than left as prose.
...and the audit's real limit is named: it does not check COMPLETENESS. Fed
the decimation defect FCST-04 was raised for it ACCEPTS, and it accepts an
empty output. So `_audit` is not what stops that recurring - the count and
identity checks are, and the text now points at them. Not made complete:
`published` is the whole read while the fill emits only [since, until), so
the rule as stated is wrong, and building it takes the 1/12/48 h horizon
checks red on a healthy feed. Measured, not assumed.
12 mutations, purged tree, every one RED, no survivors. All 29 test files
green. Nothing deployed; no option added; config.yaml untouched.

FCST-04: the carry-forward stops decimating a quarter-hourly feed, and a broken cache stops stopping the add-on
checks / unit (pull_request) Successful in 7m22s
Rework of the FCST-04 branch against review. Every finding below was proven by a runnable script before it was touched and re-run after; every check added or repaired was driven red by a mutation, `__pycache__` purged first (MUTATION.md, TEST-15). 29/29 test files green. ⚠️ H1 - A SUB-HOURLY FEED WAS DECIMATED TO ONE POINT AN HOUR, AND THE SPREAD WENT WITH IT. `fill_from_yesterday()` keyed the published set as `{_utc_hour(p.start): p for p in r.points}` - LAST POINT OF THE HOUR WINS, the other three dropped. `eneco_eddy` is the Belgian imbalance product and settles per QUARTER, and `_validate_raw()` accepts any strictly-increasing spacing, so this is a shape the product supports today. Measured on a 96-point quarter-hourly feed - ALL FIRM, FULLY PUBLISHED, nothing to carry: the plan reached the optimiser as 15 points, the arbitrage spread fell from 0.143 to 0.014 EUR/kWh, and the cheapest "hour" became a `:45` point whose `at()` window runs into the next one. Not the windowing effect this card is about; a feed losing 84 % of its own prints, with no flag anywhere reporting it. The fill now decides only WHICH WHOLE HOURS NEED CARRYING: every published point inside the window passes through BY IDENTITY, and a carried point is added only for a whole hour with no published coverage at all. Same feed, same fixture: 60 of 60 firm points kept, spread 0.134 over the hours still ahead. ⚠️ AND `_audit()` GOT STRICTER, NOT LOOSER - that was the condition on doing it at all. The old post-condition refused any repeated `_utc_hour`, a count that cannot express four points in one hour. Two rules replace it and SUBSUME it: a published point must BE one of that hour's published points by identity and may be emitted only once; a carried point may stand only in an hour absent from the published set, must be flagged True, and may not repeat. So the duplicated carried hour it existed to catch still raises, the same published point emitted twice now raises, and a carried point sharing an hour with a real print now raises too - which the count never looked at. Three mutations, three reds. ⚠️ H2 - A DAY RECORD THAT WAS NOT A RECORD STOPPED THE ADD-ON FROM STARTING. `_load()` validated `version` and that `days` is a dict, never that each VALUE is one. `{"version": 1, "days": {"2026-01-14": "oops"}}` loaded as ok=True, last_error=None, and then `rec.get(...)` raised AttributeError out of `words`, `yesterday()` and `resolve_tariff()` alike. `PriceHistory(...)` and `.words` are both unguarded in `Controller.__init__`, so the controller did not come up - and it never self-healed, because `_remember()` raised on the same record before it could reach `_save()`. That falsifies the CHANGELOG's "A BROKEN CACHE IS NOT A BROKEN CONTROLLER" in the one direction that matters. The asymmetry that produced it is visible in the file: `_parse_points()` is carefully defensive about every field of a POINT and `_load()` was not defensive about the record holding them. Unusable records are now dropped and REPORTED (`words` says how many and why), and `words` is total by construction as a second line. M3 - `yesterday()` WAS OFF BY ONE DAY FOR 00:00-00:59 AFTER SPRING-FORWARD. `brussels()` renders at the FIXED offset for that instant, so `brussels(stamp) - timedelta(days=1)` subtracts 24 ABSOLUTE hours - and the Brussels day before the March transition is 23 hours long. At 2026-03-30T00:30+02:00 it returned 2026-03-28's prices as "yesterday", or `no_data` naming a date that is not yesterday. The arithmetic is now on the local DATE, which has no offset to lose, and both transitions have a check - the module's headline claim had none. M4 - WITH NO /data THE STORE STILL FILLED, IN MEMORY. `_save()` short-circuited on `not ok` while `_remember()` populated `self._days` anyway: `words` said "unavailable" and `yesterday()` answered A SERIES that is gone on the next restart. The module docstring rejects exactly that ("a yesterday that silently forgets") as its reason for not calling makedirs, so the code now matches the docstring rather than contradicting it. M5 - THE PRUNE MUTATION SURVIVED BECAUSE THE STIMULUS WAS DEGENERATE. §8's clock-jump check seeded ONE day, so `if len(self._days) <= KEEP_DAYS: return` fired and the body it is named after never ran: pruning by arithmetic against the clock - which empties the store on exactly the morning the fill is for - passed the whole 29-file suite. The fixture is now written to a file and reopened (`_load()` does not prune, which is how a store legitimately holds more than the cap) with KEEP_DAYS + 2 days, and the mutant is red. M6 - THE AST ORDERING CHECK COULD NOT CATCH A REVERSAL, AND TWO DOCUMENTS CITED IT AS A GUARANTEE. `_calls.index("_remember") < _calls.index("yesterday")` grades `ast.walk` BFS DEPTH: `self._remember(...)` is a statement and `self.yesterday(...)` is an ARGUMENT of the fill, one level deeper, so `_remember` came out first whichever statement was written first - shipped and reversed both scored True. It is now line numbers AND, the half that matters, the behaviour: a feed carrying yesterday alongside today into an EMPTY store must fill the whole horizon; reversed, the lookup finds nothing and the plan is only the published hours. Reversing the two statements is red on both. L14/L9 - KEEP_DAYS = 3 IS THE STEADY STATE EXACTLY, so a newest-N cap has no slack: a feed publishing to D+2, or ONE stray point in the wrong year - which sorts LAST and can never age out - pushes yesterday out for good. `_prune()` now PINS the two days a lookup can actually ask for on top of the cap. Pinning is additive, so it can only RETAIN and the WITNESS-03 property (nothing is deleted by clock arithmetic) is preserved by construction; `stamp` stops being a dead parameter; the store is bounded at KEEP_DAYS + 2. L8 - the horizon end was not floored while `since` was, so a 48 h request made at any instant off the hour returned 49 points. §1's count was green only because its NOW was exactly :00:00, a shape production never has; the fixture now sits at :17:43. L10 - a failed `_save()` leaked its temp file; at 48 writes a day a persistent write failure leaked 48 inodes a day onto the volume that was already the problem. L15 - `{"version": 1.0}` passed, since `1.0 == 1`. L16 - the `_remember` tree walk scanned `app/*.py` only and matched a bare string; it now parses `app/`, `tools/`, `scenarios/` and `estop/` and looks for the NAME, so a comment does not fail it and a call in `tools/` cannot pass unseen. CLAIM-ACCURACY DEFECTS, WHICH THIS REPO TREATS AS REAL: * L7. DOCS said "*Tariff* on the status page reads `provisional` through the morning". FALSE - `tariff_words` is assigned only from the HA price-entity branch and from `static_status()`, both on the 30 s tick, and the plan's own sentence reaches `_LOG.info`. The doc now says what an operator can see (the Price history row, the Arbitrage row's own refusal sentence, the refresh log line) and a check pins the PAIRING - wiring the plan into the row is fine, correcting the doc is fine, doing one without the other is red. * L11. "fills EVERY unpublished hour" is conditional: a partial yesterday leaves the local hours it never held out of the series (§11.4 for those hours, and `at()` raises rather than answering). Correct behaviour, overclaimed wording, and untested - all three fixed. * L12. DECISIONS §1 leaned on `TariffPlan.cheap_now()`, which has NO PRODUCTION CALLER on the provider plan (`self.cheap` comes from `static_status()`, which builds its own). The conclusion holds on `arbitrage()`'s firm-pair refusal alone, which does reach control; the evidence is now stated at the reach it has. * L13. §1's "passed through by identity" check compared `eur_per_kwh` between two SEPARATE `resolve_tariff()` calls, where `is` could never have held. The value comparison is kept and now says what it grades; identity is graded on a read the file constructs and still holds. * L17. `PriceHistory.words` and the new status row had no check at all - and `words` is one of the two things H2 crashed. Both now have one. * L18. main.py's inline note carried the "widens what the optimiser can SEE, never what it may act on" guarantee without the windowing caveat that the CHANGELOG, DOCS and `resolve_tariff()`'s docstring all carry. It is the one place a maintainer reads it unqualified. EVIDENCE. All eight reviewer proofs re-run: p1/p1b return 29 March, p4 keeps 60 of 60 firm points at spread 0.134, p5 starts and reports, p6 D leaves no temp, p6 E refuses 1.0, p6 F records nothing, p7 returns 48 for 48. p2's script still scores True/True because it re-implements the OLD algorithm - the reversal is now driven as a mutation instead, and is red. p3's script always showed the shipped code correct; what was wrong was the fixture, and its mutant is now red. Twenty mutations driven, no survivors, tree fingerprinted and `__pycache__` purged before each: decimation (2 suites red), audit x3, unfloored `until` (2), unvalidated day records (7 checks), instant-subtraction yesterday, in-memory fill on a volume-less store, clock-arithmetic prune, cap without the pin, leaked temp, loose schema type, empty `words` (5), reversed `carry()` (2), a `_remember` leak in tools/ spelled two ways, a neighbour-filling fallback, a copy instead of identity (2), the DOCS claim in both directions, and the caveat removed from main.py. Baseline and the unmutated tree both green. No option added, config.yaml untouched, and the CHANGELOG entry still picks no version: PKG-07's rule, and only the deployer knows whether 0.9.0's image has been pulled.

TEST-15: purge the bytecode cache before a mutation run, not after
checks / unit (pull_request) Successful in 3m35s
FCST-03's developer reverted `self.provisional` to `here.provisional`, re-ran, and reported the mutation as a survivor. It was not one. CPython validates a cached `.pyc` on (source size, source mtime truncated to whole seconds), and that edit moved neither number - same length, same second - so the interpreter loaded the bytecode it already had. Disassembly settled it at the time: the source read `here`, the running code loaded `self`. A mutation run had graded code that was not there, with no error and exit status 0. This does not make the results already on the record wrong. It makes them UNVERIFIED, and that distinction is the whole card - so nothing here re-runs a campaign and nothing here quietly assumes the old numbers hold. REPRODUCED, THEN CLOSED. test_bytecode.py builds a real package whose two return values are the same length, imports it in a real subprocess, rewrites it inside the same second (retrying until both writes land in one whole second - milliseconds, no sleep) and reads back which value ran. Part 1 shows the interpreter running SELF off a file that says HERE. AND THE TWO OBVIOUS MITIGATIONS DO NOT WORK. Measured, not read off documentation: `python3 -B` and PYTHONDONTWRITEBYTECODE=1 are write-side only. Neither stops an EXISTING stale .pyc being read, and a mutation run always has one, because the previous run wrote it. Part 2 grades both still running the old code. The advice in test_control.py's coverage audit led with `-B`; it is corrected here - the purge is the half that works, and `-B` earns its place by keeping THIS run from leaving a cache for the NEXT edit to inherit. NO SLEEP ANYWHERE. One-second mtime resolution is the mechanism, not the enemy. Waiting it out would slow every run down and would still only cover the edit somebody remembered to slow down. THE HARNESS. tools/mutation_run.sh purges, prints a sha256/byte fingerprint of every app/*.py it is about to grade - so a mutation report can say WHICH source produced it, which is the reviewer's addition to this card - runs each suite under `python3 -B`, refuses a tree with no test_*.py (CI-01's rule, for CI-01's reason), and fails if a cache appears during the run. It takes the tree as an argument so the infra repo's replay harnesses can call it without being moved. WHERE IT IS SAID (AC 2). MUTATION.md carries the mechanism, the measurement, the reporting rules and the survey, and every one of the 16 suites now points at it from its docstring. That list is DERIVED FROM THE TREE by test_bytecode.py part 5, so a new suite that joins this directory without the pointer is red - the same failure shape CI-01's file glob exists to prevent. CI WAS ALREADY IMMUNE, AND IS DESCRIBED THAT WAY (AC 4). Verified rather than reasoned: with the checkout bind mounted `-v "$WS:/w:ro"` the interpreter writes no __pycache__ into the tree at all, and it fails SILENTLY - no error, exit status 0 - while the same probe on a writable mount produces one. Each job also rm -rf's its workspace and clones afresh, so nothing crosses between jobs on the shared runner. PYTHONDONTWRITEBYTECODE=1 is added as belt and braces only: the `:ro` is one character wide and the next person debugging a write will be tempted by it. Part 6 grades both ON THE DOCKER COMMAND LINE rather than on the file - the first draft searched the whole workflow and stayed green after the flag was deleted, because the comment explaining it still named it. THE SHIPPED ADD-ON IS NOT AFFECTED and the question is closed: goodwe_controller/Dockerfile has set PYTHONDONTWRITEBYTECODE=1 since it was written. There is no deploy-side finding. THE SURVEY (AC 3), in MUTATION.md, scoped BY THE PROPERTY. The defect is one-directional - a mutation that never took leaves the suite green, so stale bytecode manufactures SURVIVORS and cannot manufacture a red - which puts every "all red, no survivors" claim in the window out of scope, along with mutations executed in-process (SAFETY-07's B1/B2/B3, test_peakguard parts 7 and 10, where no source file is edited) and everything run after the purge discipline landed on 2026-08-31 (SAFETY-24, SAFETY-26, OPT-04, FCST-03's re-run). What is left is the recorded SURVIVORS from source-edit runs before that date. Two were re-run here under the harness and both still stand: TARIFF-01's record_block() ignoring its policy argument, and SAFETY-03's abs() on the clamp limit - 15 suites green each, on the tree as it stood. The rest are labelled still-unverified rather than assumed or re-run; each is one harness run to close, and the moment to spend it is when somebody next touches that module. OUT OF SCOPE AND RECORDED: the infra repo's sim/ replay harnesses import the add-on and write bytecode into both trees (goodwe/sim/__pycache__ exists today), so SAFETY-02's headline replay carries the same exposure. mutation_run.sh takes a tree argument for exactly that, but the change belongs in that repo and some of those harnesses want the rig. RED AND GREEN. Every new check was broken and watched fail: the purge commented out of the harness turns part 4 red (and its non-vacuity probe already proves the fixture would mis-grade without it); one docstring pointer removed turns part 5 red naming the file; `:ro` and the `-e` flag removed from the workflow turn part 6 red. Full suite green, 16 files, in the CI image on a read-only mount - the shape the runner uses. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

OPT-04: charge cheap, discharge expensive - and only when it pays
checks / unit (pull_request) Successful in 3m16s
Four cards built the price stack and nothing traded on it. app/arbitrage.py is §10.1's priority 3, and it consumes all four rather than re-deciding anything: whether a trade is permitted at all, on which two hours, against which widened threshold is TariffPlan.arbitrage()'s answer, and that answer cannot be obtained without first saying whether the peak guard is holding. §9.1's "peak shaving outranks arbitrage" is therefore honoured structurally - there is no path to a spread that skips the question - and again in the arbiter, where P_PEAK (50) clamps a claim filed at P_ARBITRAGE (30). A guard that never ran is not a guard that is clear. On meter_source off the peak guard is never evaluated; that third state is carried as None and refuses, because charging at the rail creates the billed quantity while nothing measures the quarter. validate.py refuses that configuration too, along with arbitrage armed with no price source and a SoC floor at or above the ceiling. §17: never export into a negative price. The guard is on the hour being sold into, not on the spread - a day priced -0.30 .. -0.05 clears any threshold and its dearest hour is still negative. Buying in a negative hour stays allowed. resolve_tariff() may open an HTTPS connection and the tick feeds the ESP32 heartbeat, so the fetch runs in its own task at a 30 min cadence and the tick reads an attribute and an age bound. test_arbitrage.py section 8 asserts that structurally on the shipped AST: a fetch put back on cycle() is red. AC4 is NOT met and is not restated - this repository holds no price history. Section 7 replays a synthetic year and asserts the property that does not need real prices: every executed round trip cleared its own widened requirement, and zero discharges landed in the 522 negative-priced hours. At the shipped 0.10 EUR/kWh threshold a realistic Belgian day/night site does not trade at all. Reported, not tuned: that number and FCST-03's widening factors are one product decision and it is the owner's.

Merge release/1.0 (SAFETY-07) into FCST-03, and close two degenerate stimuli
checks / unit (pull_request) Successful in 3m13s
CHANGELOG.md was the entire collision - SAFETY-07 lands in peakguard.py, main.py and the arbiter, none of which this branch touches. Both entries kept. X1. `_firm_or_die` guarding only `cheapest` survived, because the check passed the SAME provisional point as both cheapest and dearest: a guard on either role alone raises, so the stimulus could not tell "the buy hour is guarded" from "both are". Now one call per role with a firm point in the other seat, plus the positive arm so the two refusals are discriminating. X6. `firm_points()` returning the carried hours too survived, because its two consumers - the §11.4 refusal and cheap_now - guard provenance independently and both keep answering correctly. The accessor is now graded directly: exactly the published points, by identity and in order. Both are the degeneracy rule this file states at the top, in a new dress - a stimulus that cannot distinguish the two things it grades. ⚠️ AND THE REASON THE M9 MUTATION "SURVIVED" IN MY EARLIER REPORT: a stale __pycache__. Reverting `self.provisional` to `here.provisional` changes neither the file size nor, at one-second resolution, the mtime, so CPython kept the MUTATED bytecode and a green run afterwards proved nothing about that line. Every mutation here now clears __pycache__ first; re-run that way, M9 is caught. The committed source was always correct - the checks were not being run against it.

FCST-03: yesterday's prices, flagged as yesterday's, and unable to move anything
checks / unit (pull_request) Successful in 2m43s
§8.3 fills the hours a day-ahead feed has not published yet with yesterday's profile and flags them provisional, and forbids any irreversible action on such a price. The whole risk of this ticket is one line - a carried point and a published point are three fields and a bool, so `provisional=y.provisional` copies yesterday's False onto today's guess and produces stale data presented as current. That is SAFETY-18's frozen-but-fresh meter one layer up. So the flag is never passed through. Carried points come from a constructor with no provisional parameter; published points pass through BY IDENTITY, so no copy exists that could lose one; an audit re-derives the expected flag for every emitted point and raises rather than repairing; and the check walks the module's own AST so the pass-through idiom cannot come back looking ordinary. A published point may itself be provisional (eneco_eddy's imbalance print is), so the rule for a published hour is "whatever the feed said", never False. The fill keys on the Brussels wall clock rather than t-24h, so the 23- and 25-hour days are right; a late publication rebuilds the series, moving the number and the flag together. AC2 and AC3 landed on TARIFF-03's existing verdict surface rather than beside it. Refusal 3 became "fewer than two FIRM hours" - refusing on "any point is provisional" would have switched arbitrage off every morning on every dynamic site - and refusal 5 is new: the spread must clear a threshold widened by the widest active uncertainty source (max, never a product). The permitting variant now refuses to be constructed around a provisional point at all, and the cheap-window flag became per-hour for the same reason. The irreversible action is a value carrying the hours it commits, derived from maintenance.py's own DRAIN_TIMEOUT_MIN; the gate blocks a maintenance drain whose window reaches into a carried hour, and the phase machine stays idle. It is the price-justified entry point only - a gate that blocked on no_data would stop the monthly cycle on every default install. Zero new config options; TEST-14's signature scan ported to cover both Gate's and Arbitrage's constructors, closing _Refused.reason's open hole.
