FCST-04: the carry-forward fill reaches the plan, and the day it carries survives a restart
checks / unit (pull_request) Successful in 7m11s
FCST-03 shipped `fill_from_yesterday()` complete and checked, and shipped the consumers written for it - `TariffPlan.firm_points()`, `cheap_now()`'s refusal of a provisional hour, and `arbitrage()`'s refusal 3, which drops provisional hours from the trade set rather than refusing the whole series. It shipped NO CALLER. Nothing in `app/` named the fill, so no series ever contained a carried point and every one of those consumers was exercising its all-firm branch. ⚠️ THE DEFECT THAT PRODUCED WAS NOT AN ERROR ANYWHERE. `load_prices()` returns what the feed published and nothing widened it to the requested horizon, so on a dynamic site between midnight and the 14-16 h CET publication the plan covered the rest of today and nothing more - measured on the fixture here, 24 h against a 48 h request. `arbitrage()` then took `max - min` over that truncated window and reported a spread. The number was real, the window was half the one configured, and nothing said so: tomorrow evening's peak, the hour a morning charge would be sold into, was not in the series to be compared against anything. A missing hour is not a wrong price - it is an hour the optimiser never learns exists. WHAT THIS ADDS. `app/price_history.py` keeps the PUBLISHED prices of the last KEEP_DAYS Brussels days in /data/price_history.json; `resolve_tariff()` gains a required keyword-only `history` and fills every unpublished hour of the horizon from yesterday's same-wall-clock hour, flagged. Persistence rather than a variable on the refresh task, because the window the fill exists for is midnight -> publication and an add-on restarted at 08:00 would otherwise spend all of it on the truncated series. Not in state.json: the refresh runs every 1800 s and that file holds the maintenance history and SAFETY-02's latch. ⚠️ ONE CHANGE HERE MOVES ENERGY, AND IT IS NOT THE ONE THE CARD IS NAMED FOR. Carried hours are provisional, so §8.3 keeps them out of the trade set: the fill widens what the optimiser can SEE, never what it may DO, and test_price_history.py checks that so it cannot be overclaimed later. What does change a trade is that the filled series is windowed to [since, until), so hours that have ALREADY ELAPSED are no longer in the spread. Before, a cheap night that had gone sat in the series as the day's cheapest hour - and a cycle cannot buy in an hour that is past, so the trade was quietly never taken. Section 2 grades this by finding the cheapest firm hour with and without the fill and showing it MOVES, from 02:00 UTC to 08:00 UTC on the fixture. ⚠️ A DEAD FEED IS STILL §11.4, NOT YESTERDAY. The fill runs only on a `series` read. The two are indistinguishable to the optimiser - both 100 % provisional, so arbitrage refuses on the firm-pair rung and `cheap_now()` is False - so preferring yesterday's feed over the `static_profile` an operator configured FOR that case would change a documented degradation for a difference only the status page can see. That, and two more, in DECISIONS/FCST-04-the-day-that-is-carried.md. ⚠️ THE ANTI-DECAY RULE IS AN ORDERING, NOT A VALIDATION, and saying so is more useful than a guarantee that would not hold. Feeding the filled series back in is how this rots - day 2 carries day 1's guesses, day 3 carries day 2's carry of them, behind a `provisional` flag that stays TRUE while the NUMBER decays. No value-level check can catch it: a carried point and `eneco_eddy`'s published-provisional quarter are the same three fields with the same flag. So `carry()` is the only public entry, it records BEFORE it fills, the filled series exists only as a return value the object never sees again, and test_price_history.py walks app/ for any other module naming `_remember` and reads `carry()`'s AST to pin the order. EVIDENCE. 29/29 test files pass in the CI image. Eight mutations driven against app/price_history.py and app/static_tariff.py, __pycache__ purged before each run per MUTATION.md/TEST-15: newest-record lookup (5 red), recording the filled series (1), replace-instead-of-merge (10), UTC-date keying (10), removing the fill call entirely (12), a lost price field defaulting to 0.0 (2), prune by clock arithmetic (1), a degraded reason that stops naming its cause (1). No survivors; baseline and revert both green. Three of those first crashed the harness instead of reporting a FAIL - "it was refused" and "it broke on the way to being refused" must not grade the same - so `why()` and `_priced()` were added and the run repeated. No option added, config.yaml untouched, and the CHANGELOG entry deliberately picks no version: PKG-07's rule, and only the deployer knows whether 0.9.0's image has been pulled.

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.

TARIFF-03: static day/night and fully-fixed tariffs, first-class
checks / unit (pull_request) Successful in 2m43s
§9.2 puts a large share of the Belgian installed base on a static profile, and
an EMS that only works under dynamic pricing is an EMS for a minority. A new
`static_profile` option describes a two-period day/night tariff - or a single
fixed price - and app/static_tariff.py turns it into the same canonical
{start, eur_per_kwh, provisional} series the fetched providers emit.
Not a sixth provider plugin, for two mechanical reasons. capabilities() is a
classmethod, so a plugin's PriceProduct is fixed when the class is written -
but §9.2 makes STATIC and FIXED two different products and which one a site is
on is a property of the operator's data; StaticProfile.product derives it from
the number of distinct prices. And the plugin framework exists to stop a
FETCHED figure being marked up twice, which a number typed as all-in cannot be.
So the profile sits where §11.4 already says it does - under the providers, as
the fallback. Configured product and feed-is-down are one generator differing
in one flag, so the degradation path cannot rot unused.
"No arbitrage" is a type. TariffPlan.arbitrage() returns a variant whose
ALLOWED arm carries the spread and the cheapest/dearest hours and whose REFUSED
arm carries a reason and nothing else - .spread_eur_kwh on a refusal raises
rather than answering 0.0, so an optimiser cannot compute a trade from one.
Four refusals, all derived: peak guard holding, no price data, plan
provisional, or the series is FLAT. The last is AC2: a fixed tariff disables
arbitrage by arithmetic, not by matching on an enum. peak_guard_active is a
required keyword argument, so §10.1's priority 2 over 3 cannot be skipped.
Time-window shifting reaches the one shiftable load that exists: main.py's
cheap-window flag falls back to the static profile, and the UI gained a Tariff
row. Cheap is STRICTLY below the seven-day mean - `<=` would call every hour of
a flat tariff cheap, and 48 h taken on a Friday is two-thirds weekend.
A profile must tile every day type exactly once, checked at startup; a gap is
refused with the range named rather than filled in. `22:00-07:00 mon-fri` does
not cover Saturday morning, and that trap is what the check catches.
validate.py rule 7's stated reason expired exactly as TARIFF-02 predicted: the
test_price.py section 12 tripwire went red naming static_tariff.py. The message
now says what is true instead, and the tripwire is re-aimed rather than removed
- consumer set pinned, expired phrase asserted gone. Rule 7 also grew a second
refusal for static_profile alongside the HA price pair, the same silent-loser
conflict and a live one.
CFG-03 is not widened: static_profile went into price.py's PRICE_OPTION_DEFAULTS
- the one in-code mirror pinned to config.yaml by a check - and the new module
carries no defaults dict of its own.
Measured on the two committed days of this house's real P1 meter. 2026-08-20
(Thursday): 15.220 kWh imported, 9.606 day / 5.614 night, EUR 4.7185 under
day/night vs EUR 4.6725 flat, shifting saves EUR 0.8069 = 9.606 kWh x the
0.0840 spread, derived twice. 2026-08-23 (Sunday): 0.728 kWh, all of it
night-priced, which is the weekend row proving itself. §17 names six Belgian
scenarios; this is the seventh, and it is two days rather than a season - the
file says so rather than implying an annual figure.
All 12 suites green. Eleven mutations of static_tariff.py were each caught by
at least one check.
