A dashboard canvas is CSS-scaled to fit its panel while uPlot maps the
pointer against its own unscaled plot width, so the cursor drifted further
right the further into a chart it went. A `cursor.move` refiner divides the
visual offset back into layout pixels; unscaled hosts get a no-op.
A querying chart's range picker moves onto the frame's title line through a
new `useHeaderSlot`, giving the plot back the row it spent. The editor's drag
handle is the header, so the picker is exempted from it.
Charts can be drawn as a monotone cubic spline — uPlot's own path builder,
monotone so a smoothed line never invents a reading between two real ones.

Both screens the house is looked at on are 1280x800, so that is what the three
dashboards are laid out for: twelve columns of 96px, twelve rows of 51px, and
nothing past the bottom, because a panel does not scroll.
The motors are one control each instead of three buttons. A button could only
publish; a segmented control reads back as well — so the motor writes what it
is doing to the same message the control sets, and the segment that is held is
the direction it actually went. Up, Stop, Down for the shutters; Close/Open for
the window and In/Out for the awning, which is what those two are for.
A run stopped part way now leaves the position unknown rather than claiming the
target it never reached, so the next command in either direction moves it.
The preflight gained the two checks this needed. One runs each sample shape
past the port that would receive it. The other is arithmetic: every tile inside
the panel and none on top of another — both silent failures on a screen with no
scrollbar, and both caught before anything is written.
Sizes were settled by looking. A slider needs three rows or its tick labels
fall off; a status icon needs three or it loses the word under the glyph; a
gauge in two rows has no arc worth reading, so the battery is a bar on Home and
a gauge on Energy where there is height for one. A chart spends eighty pixels
on its chrome whatever it is given, so two of them read on this panel and three
did not — the temperature history is the one that went, and `history` still
answers for it.
`capture-panels.mjs` is how that was checked: the three panels at the screen's
own pixels, in both themes, reporting whether anything spilled.

An inject left to itself emits the current time. That went into a port
declared `str`, the node raised on every tick, and after five the supervisor
quarantined the whole `power` flow — which is every Victron reading in the
house. It was invisible because Node-RED is still sending its own keepalive,
so the Cerbo kept publishing anyway; the first thing to notice would have
been the data stopping some minutes after Node-RED did.
The preflight now checks what an inject emits against the port that receives
it. Nothing else could: an inject has no source to run, and both halves of
the declaration agreed with each other while disagreeing with reality.

Watching it decide — which is what `commands: false` is for — caught two
things a type check never would.
It wanted to cool the house to 21 degrees in August. The comfort band is what
*heating* aims at; the reference cooled above 26 and at night above 24.5, and
this port had collapsed the two into one number. A compressor running every
summer afternoon to reach a heating setpoint is the most expensive kind of
correct-looking bug.
And it was willing to heat while the pellet stove was doing the same job. The
reference only ever let the heat pump heat when the stove reported itself
faulty, which is the right way round: the stove is what heats this house and
the pump is what covers for it.
Both tables now have a check behind them, along with the boilers' — the three
places in the house where a wrong threshold is a bill rather than a mistake.

Two things the installation found that the checks did not.
A script with three `from()` statements in it produces three results all
called `_result`, and InfluxDB refuses that outright — so the measurements go
into one filter and the rows come back tagged with which one they are.
And the answer a database node hands back holds a *list* of rows, which a
record may not: a record is flat scalars. It was declared one, so every chart
failed on the type check the moment a real answer arrived.
The second one is now caught before anything is pushed: the preflight runs
each sample shape past the port that would receive it, which is what turns
"expected record, got dict" from a runtime surprise into a line of output.
Also records the two engine faults this seeding session surfaced.

Sharing after the flows were created left every flow between the owner and
the end of the list pointing at a library entry that did not exist yet. A node
that fails to load provides nothing, so one missing entry reported as inputs
nothing carries, in eighteen places.
The library is written *from* a node, so this is one throwaway flow that
carries both sources in and is deleted again — the entries outlive it. Order
stops mattering, which also covers the case that would have broken the
previous fix: two instances of one shared node inside a single flow.
Verified against the installation: nineteen flows, zero validation issues.

A node type accepts a setting it does not know and ignores it, which is right
for a node someone is editing and wrong here: seeded against the engine this
installation is running today, every rollershutter would take the trigger's
default minute instead of the twenty-six seconds it actually takes, and every
Victron reading would arrive as an object where a number was declared. It
would look like it had worked.
So the seed asks what the node types know before it writes anything, and says
which rebuild is missing.

The Node-RED installation this replaces is 865 nodes across three tabs, and
roughly a fifth of it is unreachable — the pellet stove's controller, the
scene engine and the awning's logic were all disconnected from the heartbeat
they ran on. What is here is the intent rather than the wiring: nineteen named
flows, 109 nodes, and no heartbeat at all. A sensor value is the event.
The device layer moves with it. `actor/*` and `light/*` were never a device
interface — Node-RED subscribed to its own topics, stamped a DMX channel on
each and encoded one Art-Net universe — so those topics retire with it and the
encoders are five nodes in the `dmx` flow.
Two shared library nodes carry what every actuator needs.
`arbiter` answers the thing this design was missing: a value someone sets on a
screen is not undone by the next evaluation. A manual value wins for a hold,
the house takes over when it expires, and a schedule can force past both — so
"off at two in the morning" still means off. The control binds to the message
the arbiter writes back, so one tile shows what reached the fixture and
setting it is the override.
`motor` is why a stop is now commanded once. A rollershutter has no position
sensor, so time is the only feedback: it says how long to run and a trigger
sends the single STOP that ends it. The reference sent STOP forever.
Everything is seeded stopped, the Art-Net node does not transmit and the heat
pump does not accept commands until house.json says so.
`--dry` checks the whole set without an installation: names nothing provides,
loops, type disagreements, widgets bound to nothing, and every Python node run
once on values of the shape it declared — including whether what it returns
goes anywhere. That last one has already caught a typo that would have
published into silence.
house.json holds this installation's addresses, MAC addresses and DMX map and
is git-ignored, as the Node-RED inventory is.

A dashboard could only ever receive as a set of tiles. This adds the dashboard
itself as a receiver: `settings` maps a name to a value plus an optional
binding. Unbound, the setting is simply its value — a wall panel that is always
dark costs no flow. Bound, a flow drives it live and the value is the fallback.
Two settings are wired: `theme` (system/light/dark) and `locked` (read-only).
There is no schedule field on purpose — a node publishing to the bound message
on a cron is what a schedule is here, which is the point of a channel.
- `messages_for()` now walks a dashboard's bound settings as well as its
widgets' bindings. Without this a paired screen is refused its own theme
message, on the one surface the setting exists for; it bounds the socket too.
- `locked` is gated in `usePublish`, so every control inherits it, and each
control also draws itself disabled — a dead button reads as broken otherwise.
The panel surface says Read-only in the corner.
- The theme is a class on the dashboard's own surface, never the root: inside
the app shell it must not flip the chrome. `.light` gains the tokens `.dark`
already had (mirrored in the index repo) so both directions work on a subtree.
- Settings bindings are type-checked from the document alone, the rule widget
bindings follow, and mirrored on the server.
- A bound setting is drawn on the flow canvas as a dashboard-level endpoint.
- The demo's house flow now publishes `home.panel_theme`, which the demo
dashboard's theme binds to: the panel goes dark after sunset, at no tile cost.

A custom hue ring — a conic gradient, not a canvas — with saturation and
brightness sliders beside or under it depending on the tile's shape, sized
for a wall panel and reachable from a keyboard. It publishes [h, s, v] by
default, which is what the reference installation's DMX encoders read, and
`format` switches that to [r, g, b] or "#rrggbb".
`usePublish` moves to its own module so a widget in a file of its own can
reach it without importing `widgets.tsx` back.
The panel now carries one wfrac node per unit, polling as well as commanding,
so a command can be checked against the unit's own answer rather than assumed.
Three things kept a panel from driving the old unit. The seeded commands catch
is off by default, which is the usual reason a fresh panel looks dead;
AIRCON_COMMANDS=1 arms it at seed time. A unit that is off names no mode, and
a flow redelivers every bound port on each run, so that rejected value blocked
every command including power-on. And the old firmware serves one connection
at a time.
A wheel whose top-level module is `app` collides with anything else in a
user's venv, so the package that is about to be published takes the name
it is published under. Only the Python package moves; the repo, the
Docker WORKDIR and the compose project keep theirs.

`make lint-frontend` was `biome check --write --unsafe ./` — a lint target that
reformatted the whole tree rather than checking it, which is why every parallel
change in this repo has had to work around it. `lint` checks now and a new
`format` writes. The pre-commit hook and CI needed no edit at all: both call
`bun run lint`, so they became checks the moment its meaning changed.
`app/Makefile` assigned DOMAIN from .env, and a plain assignment beats an
inherited environment variable and is not exported — so `cd app && make
dev-local` served localhost while the same checkout's tests targeted the
configured domain. `export DOMAIN ?=` gives the lattice that was intended:
command line, then environment, then .env.
Alongside: the backend's htmlcov bind mount created that directory as root, so
`make test-backend` died on the coverage step after every test had passed,
which reads like a test failure and is not one. The alerts screen's copy of
ALERTING_EVENTS is now checked by a test rather than trusted. And the shard
comment claimed two spec files where there are nine.

A dashboard went live the moment it was created — an empty document straight to
the panels — while a new flow starts as a draft. It now works the way flows do:
published means `dashboard.json` exists, so every dashboard on every running
installation is already published and nothing needs migrating. Only the ones
created from here on start as drafts.
Mirroring FlowStore turned up a latent 500: discarding the draft of a dashboard
that had never been published unlinked its only file, and the read that followed
raised out of a 200 handler. It answers 400 now, the way a flow does.
Publishing all of them was 2N requests, because a publish has to name the
version it expects and the summaries did not carry one. They do now — and so do
the flow summaries, which had the same defect nobody had written down.
A panel had no way to hear about any of this. A publish, or a change to which
dashboards a panel carries, now puts one event on the bus and the screen
refetches what changed: no reload, so a wall display never blanks or asks for
its credential again. The subtle half is that a socket's message allowlist was
computed once at handshake — a reassigned panel would have fetched its new
document and then shown tiles that never updated.
The panels dialog logged non-superusers out. Every write in it needs a
superuser, not only the checkboxes the report mentioned, so the dialog is
read-only for everyone else. The logout itself was `main.tsx` treating 403 as a
dead session, against the contract deps.py spells out: only a 401 ends a
session, and a 403 now says so rather than silently signing someone out.

Four controls and the unit's own answer beside them. Two catches, both on:
the flow is seeded stopped and the node's commands setting is off. The initial
values are read off the unit when the script runs, so starting the flow asks
for what it was already doing rather than commanding it to something else.
Two things stopped the engine commanding this house. ConnectorNode hardwired
its node function to a no-op, so an input message reaching a connector was
discarded and Art-Net's packet builder was unreachable; write() now carries
the input ports, which is additive so the contract version holds. And the MQTT
publisher JSON-encoded every payload, so "ON" went on the wire quoted and the
devices on a shared broker, which speak bare values, ignored it.
seed_house_control.py is the rig: a flow that drives the washing machine plug,
a dimmer and a colour fixture over MQTT, carries the same two as DMX on an
Art-Net node with transmit still off, and a dashboard to drive it by hand.
A python node's settings are constants of its own function, so they are passed
the way its ports are: by name. The controller binds them to the compiled
function, the `params` field is gone from the worker and remote protocols, and
a setting sharing a port's name is reported as a node error rather than
shadowing it. The panel's scaffold follows suit and keeps the header in step
with both ports and settings.
The demo's `pace` moves from a flow input to a setting of the training node,
which is what it always was.

`scripts/seed_demo.py` wipes and recreates one persistent demo — `home`,
`home_history` and `pv_model`, plus a `demo` dashboard carrying all fifteen
widget types across three sections. Operational script for the hosted
instance only: `make seed-hosted-demo`, with `API_URL` selecting which one.

make seed-demo builds demo_training — prepare on the engine, a GPU-bound
train, evaluate back here — and a panel that draws the loss curve while the
training is still going. It is the session's whole argument in one flow: batch
runs with parameters and a result, a generator yielding on a declared port
rather than logging, fluksio.emit from inside a callback, artifacts carrying
the dataset and the weights between machines, and a sweep whose configs are
isolated from each other. The train node prefers its label rather than
requiring it, so it runs before a GPU box exists and says which machine and
which numeric backend it actually used.
Building it turned up two real bugs. A run waited for a worker its flow only
*preferred*, because required_labels ignored device_policy — so the example
hung on a label it did not need. And a run's seed never reached the flow, so
sweeping over seeds ran the same experiment N times; it now fills an input of
that name when the flow declares one, which is what the field looked like it
did all along.
Pressing Run on a batch flow now submits a run rather than taking the old
non-durable path — that button is the first thing anyone evaluating will press,
and it was quietly doing something else.

A chart is drawn in buckets, and nothing it can show changes until the
bucket it is drawing closes — so the resolution sets the refresh rather
than a flat five-second floor. A week at quarter-hour buckets now asks
four times an hour instead of sixty, for the same picture. Leaving the
field empty follows the window; a slower rate is still honoured.
`make seed-example` builds the thing to evaluate it with: a flow that
logs a temperature to InfluxDB, a flow that answers a chart's request by
turning the window into Flux and the rows back into a series, and a
dashboard holding the chart. The reading flow declares the request as an
input with a starting value, which is how a flow says a value reaches it
from a panel rather than from a node upstream.
Axis labels keep enough decimals to stay distinct — `si` rounds to three
figures, so every tick of a chart living inside one degree read "19".
