UX-13 P4: the setup wizard for installers
The Setup tab draws the Installer view's page model one step at a time,
from each field's `wizard` step in app/uilayout.py: meter (with the kettle
test), inverters and batteries, solar (optional), prices, peak limit
(battery modes: "comes in a later update", OPT-11), check and start.
It reuses P2's controls and saves through /config/validate and
/config/save. No route was added.

- First run: /config/model says `setup_needed` when the stored options name
  no power request entity, or on a new install (no `setup_done` and no
  `auto` in the Store, control not started). The page opens #setup only
  when opened with no route. The wizard's save writes `setup_done`.
- Kettle test: GET ha/entities?entity= reads one entity now, in W. The
  change decides: up keeps meter_invert off, down turns it on; a net or
  import/export meter that goes down blocks the step with what to check.
- Last step: validate.setup_checks() beside the refusals: the meter reads,
  each power request entity exists in HA (bad if not, SAFETY-77), battery
  levels and power with direction, solar sign, prices. Saves with
  shadow_mode on by default, then a confirmed restart naming the 0 W.
- P2 test finding (a): a stale save lists only the keys the other surface
  moved (the blob handed out on open, by fingerprint, against stored now).
- test_setup.py; tools/ux13_wizard_blobs.py makes the 88 blobs the wizard
  can save; all accepted by Supervisor 2026.08.0 AppOptions (offline).

# UX-13 — one layout table, and why UI code may now name an option key
**Status: DECIDED 2026-09-27 (owner approved the UX-13 design and mockup).**
Card 6ab979852f3eca02fb40f69e. Amends [[UX-02]] §3.1. Design note and
mockup: `goodwe-session/UX-13-design.md`, `UX-13-mockup.html`.
## 1. What UX-02 said, and why it no longer fits
UX-02 built the configuration panel from the Supervisor's schema, so
`app/configui.py` contains "no option key, no label and no rule", and
test_selfconfig.py part 5 checks that the page script names no key. That kept
a second copy of the option surface from drifting, and it is why the panel is
a flat list of fields in schema order.
UX-13 needs things a schema cannot say: groups and sub-groups, a slider in kW
for a value stored in W, a picker for an entity, a field shown only for one
meter source, locked measured values, a Simple view and a setup wizard. It
also needs page fields that are not options at all: one inverter card that is
stored as six flat keys, solar rows that become `pv_entity` or `pv_entities`,
a contract and two prices that become `static_profile` JSON, and a region
that becomes the levies figure. None of that can be read off the schema, so
some code has to name option keys.
## 2. The decision
Option keys may appear in UI code in exactly two files:
- **`app/uilayout.py`**, the layout table: screen → group → part → field, with
control, unit, display scale, step, entity kind, when it is shown, whether it
is on the Simple view or a wizard step, and whether it applies now or after a
restart. Every option in `config.yaml` is a field, `DERIVED` or `HIDDEN`,
exactly once.
- **`app/uimodel.py`**, the derivations the table names: `options_to_ui()` and
`ui_to_options()`. It may name only the keys it writes.
What UX-02 made authoritative stays authoritative:
- **Ranges** come from the schema (`uilayout.range_of()`); the table writes
none. A unit holds no digit.
- **Labels and help** come from `translations/*.yaml` by key. Page-only fields,
group titles and choices are in `app/ui_text/*.json`, held to STYLE by
test_messages.py.
- **Rules** stay in `validate.py`. It gains a warning tier (`validate.Note`,
"warn" or "info") for the page. A note never blocks a save, and passing the
notes list does not change the refusals returned.
- **The stored blob** is still the one truth. The page model carries the stored
values of every derived key (`keep`). A derivation whose page fields are
unchanged writes those values back untouched, so a blob the page cannot
express survives a save of another field.
## 3. How it is held
- test_uilayout.py fails when `config.yaml` gains an option, or an inverter
field, that the table does not place. It also checks that uimodel.py names
only the keys it writes and that web.py and haentities.py name none.
- test_uimodel.py round-trips options → page model → JSON → options for every
validator call the suite made at 652097a (`scenarios/ux13/`), the TEST-23
option files and config.yaml's defaults. All must be identical.
- `tools/ux13_validator_calls.py compare` runs those calls through the old and
new validator. At P0: 261 calls, 158 refused, no refusal changed.
- test_selfconfig.py part 5 still checks the old page script; P1 moves the page
into `app/static/` and the same check applies there.
- P2: the Installer view (`app/static/settings.js`) draws from
`app/uipage.py`, which serialises the table and names no key itself
(test_uilayout part 5, test_settings part 2). The view posts its page model
to the existing `/config/validate` and `/config/save`, which turn it into
options with `ui_to_options()` before the shipped validator runs. No route
was added.
- P4: the setup wizard draws the same model by each field's `wizard` step.
Its tables (`KETTLE`, `SHADOW`) are in `uilayout.py`, and its live checks
are rules, so they are in `validate.py` (`setup_checks`). settings.js still
names no key. See [[UX-13-setup-wizard]].
## 4. What this costs
The table is a second place that knows the option surface, which UX-02 set
out to avoid. The cost is bounded by the coverage test: an option added to
config.yaml and not placed here fails CI, rather than silently missing from
the page. Changing a key's type or range needs no change here.
