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.
