The ring share drops from the wordmark's 0.231 to 0.18 so the disc reads as a
dot at 32px, and both the border and the gap are rounded where they are applied
— a fractional border snaps per edge and left the disc off centre. Connections
and their port dots go up with it, pulse width included, so an arriving message
never draws its edge thinner than it rests.

Plumbing only: the widget-type literal and its dtype table on both sides,
the regenerated client, a curated lucide map and four stubs the renderers
are wired to. Also a latching switch and a segmented dropdown, both a
`style` on the control that already publishes and reads back, plus the
option editor a dropdown never had.

The "running" tile counted paused and invalid flows as running, so it read
"5/5" beside "1 flow(s) cannot run". Its note is now additive rather than a
precedence chain, so a quarantine no longer hides the invalid count.
Adds dur() beside si(): a ms reading picks its own unit, so a slow run reads
"1.24 s" instead of "1.2k ms".

The same bundle is served by a portal under /i/{id}, so it reads its API base,
credential and router basepath from an injected config instead of the build-time
URL and localStorage. A normal installation finds no config and behaves exactly
as before; the credential deliberately never touches localStorage, since two
installations open in one browser share an origin and would overwrite each
other's session.
The websocket URL was resolving an absolute path against the base, which
discards the base's own path — harmless until the base gained one, then it
aimed the socket at the wrong host entirely.
Connection state gets a store of its own, apart from the engine's: the proxy's
503 carries {offline, last_seen}, which raises a banner naming when the
installation was last heard from and turns a failed mutation into 'not
delivered' rather than a generic error. The screen keeps its last data
underneath, since stale readings with a timestamp beat a blank page. A
reconnecting socket invalidates every query, because whatever happened while it
was down was missed.
Verified in a browser against a real hub and installation: the full UI loads
through the tunnel with no console errors, and killing the installation raises
the banner within a poll.

A record or an artifact reference was serialised into the port row, and the
panel widened until the type selects and the buttons beside them were pushed
off its edge — a checkpoint reference is 130 characters of digest, and none of
them are what you want while wiring a flow. What shows now is what the value
*is*: 'artifact · weights.json · 60B', 'record · 3 fields'. A chevron unfolds
the whole of it, wrapped, inside the panel it belongs to.
A scalar still reads as itself, and scrolls its own overflow into view when it
is longer than the room it was given. That behaviour already existed inside
the edge inspector; it moves to Common/Marquee so the panel can have it too,
and the inspector drops its own copy of the raw-JSON block along with it.
The rows are smaller for it: the type select finally fits the word 'artifact',
and a port nothing has come through on says so with a dash rather than a
sentence — nine ports of 'nothing has come through yet' is a panel of prose
about the absence of values.
The e2e check asserts both halves: that the summary is what appears, and that
the panel is still exactly 400px with the value unfolded.

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.

The first cut had node code call fluksio.log_metric, which was a second,
undeclared way for data to leave a node: invisible to validation, absent from
the canvas, and stored where the graph could not see it. That is precisely the
MLflow discrepancy this framework exists to avoid, so it is gone.
A node that produces values over time is a generator. Every yield is a dict
keyed by output port, published the instant it happens — same port, same type
check, same place on the canvas as any other value — and what it returns is
its result. A port doing this declares stream: true, and a run keeps every
number one takes, so experiment tracking is a consequence of the graph rather
than an API beside it: a chart binds to a training curve the way it binds to a
temperature. fluksio.emit writes the same ports imperatively, for where a
yield cannot reach — inside a training framework's callback.
In a live flow an emission also wakes what is downstream, as a subscriber
publishing does; in a run it does not, because a run's graph is scheduled once
and mid-node cascades would leave 'finished' with nothing to mean. The
enqueued item carries no payload: the value is already in state, and one
carrying it would re-apply an old emission after the node returned.
Verified on the stack: 30 loss values arrived live on the flow socket during a
run, attributed to the node that produced them, and the same node run on the
remote worker streamed its curve back across the socket.
Also caches remote compile results per worker, so attaching a GPU box does not
put a network round trip in every rebuild.

The engine runs where the automations are and the GPU is somewhere else,
usually behind a different network — so the worker connects out and the engine
answers over the socket it was given. Nothing has to expose Redis, and the
same connection works through the tunnel the hosted access will use.
What travels is the protocol the local pool already speaks, so a node cannot
tell which kind of worker it is on. A node declares device: gpu and
device_policy, the label is resolved per call (a worker attaching later needs
no rebuild), and a run whose labels nothing carries waits in the queue saying
what it waits for rather than failing — submit from the couch, the GPU box
picks it up when it is switched on.
Two things had to move with it. Compiling now happens on the machine that will
run the node: a node importing torch is correct on the GPU box and a missing
module on the engine, so checking it here failed nodes that were fine. And the
artifact endpoint accepts a worker's own credential, because storing a
checkpoint is exactly what that credential is for — and only that.
Verified against the real split: the training ran on this host (its checkpoint
names the machine and a numpy the engine does not have), streamed 40 metric
points back mid-run, and the evaluate node read the checkpoint on the engine.
Cancel kills the remote training; pulling the worker fails the run in six
seconds instead of waiting out its ten-minute timeout.

A checkpoint is not a message. DType.ARTIFACT carries a reference — digest,
size, media type, name — so everything on the wire stays JSON and thirty
megabytes never sit in Redis, which answers the vision's open binary-payload
question by narrowing it: inline codecs would only serve payloads too small to
be worth a round trip, and nothing asks for that.
The store is content-addressed rather than per-run, for three reasons that all
pay later: a sweep whose fifty configs share one preprocessed input stores it
once, a reference stays valid however it is passed around because it names
content instead of a location, and the digest is what a stage cache will
compare — so building it in now is what keeps that from being a change to the
message contract.
Node code calls fluksio.save_artifact/load_artifact and cannot tell whether it
is writing the engine's own directory or putting bytes over HTTP, which is
what will let the same flow run on a remote worker unchanged.

Two things the first pass got wrong.
The Changes and "Given up on" lists had no cap, so they ran as long as the
audit trail did — and worse, a truncating flex row still offers its whole
unwrapped line as a min-content contribution, so the card sized itself to the
longest entry and took the page sideways with it. Both now use the same
capped, scrolling box the runs and failures lists already had, which fixes the
length and the width together.
Running downwards, a rank of eight nodes was two thousand pixels across
because a node box is landscape: siblings cost a rank four times as much
across as they do down it. A rank wider than two now wraps onto the ranks
below, settling over a few passes since wrapping one rank pushes what was
under it up into the room that freed. The value chip on an edge no longer
reserves its width there either — that width is spent across the screen rather
than along the flow, and the rank gap it would widen is already wider than the
chip is tall. The same flow that laid out 2040x216 is now 803x722; a chain and
a diamond are unchanged, and so is every desktop layout.

The canvas lays itself out: a layered graph, left to right on a desktop and
top to bottom on a phone, with room reserved for the value each edge carries.
Nodes cannot be dragged and `NodeDef.position` is gone from the document —
a graph nobody can arrange is one worth keeping small, which is what keeps
flows atomic. Endpoints join the same layout, so their lanes and the
localStorage that remembered where they were dragged go too.
Mobile, per the new Responsive section of DESIGN-GUIDELINES.md: the dock caps
its width and wraps instead of running off the screen, the dashboard stacks
into one column rather than shrinking a wall panel to a fifth of its size, and
Home stops widening its grid track past the viewport. A Playwright project at
a phone's width fails the build when a screen no longer fits.
Along the way: publish is the checkmark that was already there rather than a
button that appears and disappears, with discard beside it on both the flow
and the dashboard; the brain reveals a neuron's name on the first tap; and the
port sparklines get room to breathe.

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".

The frame centres a single reading, which is right for a gauge and wrong
for a list.

A chart can now ask for what it draws instead of reading the ring the
engine keeps. It publishes a request — the window and the resolution —
exactly as a slider publishes a value, and draws the series a flow
answers with. What serves the request is the flow's business, so the
widget never learns which database was behind it.
The answer says what it was computed for and one computed for another
window is ignored, so two charts on one node cost a duplicate query
rather than overwriting each other's picture. Identical requests still
in flight are asked once per tab, and the refresh has a floor under it.
The panel gains the presentation the document could already hold: the
per-series label, a unit, and a y axis that can be pinned.

A series, record or list message declares its shape instead of riding
DType.JSON, so a widget binds a shape rather than some JSON and a wrong
binding is refused before anything runs. A list declares its item type,
which is what keeps list[float] expressible for a pipeline.
On top of that: an agenda over a list, a notification over a record, and
a dashboard alert channel that publishes engine faults as one — so a
panel can show what went wrong without a flow wiring it by hand.
Also: only None means a node published nothing, a falsy value of the
wrong shape is now the named error it always should have been; and the
gauge's readout says its size is viewBox geometry rather than type scale.

A dependency loop is flagged on the canvas and was invisible everywhere else:
/observability/summary answered "ok" with an empty problems list while the
published flow could not run at all. It now reports the flows validation
blocks, and the brain graph carries the reason on each neuron the issue names
so the view built to find broken wiring can show it.
Node errors stay counted once, as the nodes that failed to load, and an
advisory like an unauthenticated webhook marks nothing — it is worth saying,
but the flow still runs.

The Home table drew the one sparkline without its live dot, on the grounds
that a polled rollup's right edge is the last complete slice rather than this
instant. Identical curves reading differently is the worse trade, so the dot
is back everywhere and the cell keeps room for the half that hangs past the
curve.

Both overviews carried the same toolbar twice, left-aligned, with a search
field permanently taking a row of width. One `OverviewToolbar` now serves
them: the search folds into an icon and expands again on click (Escape puts
it away and hands focus back), create is a `+`, and everything sits right of
the page. Each page keeps its own create dialog — the toolbar only renders
the trigger — so the testids the runtime spec and the capture script drive
stayed where they were.
Dashboards get the flow store's draft/publish split. The editor autosaves
`dashboard.draft.json` beside `dashboard.json`; `/view/{name}`, `bindings_for`
and `history_requirements` keep reading the published file, so a wall panel
sees an edit only once someone publishes it. `POST /dashboards/{name}/publish`
and `/discard` mirror the flow routes down to the version precondition and the
409, `GET /dashboards/{name}?draft=true` is what the editor asks for, and the
dock grows the same Publish button — which flushes a queued save first, so an
autosave in flight is not published around. Creating a dashboard still writes
the published file directly: an empty document on a panel is harmless, and it
keeps the store free of a never-published case.
"Publish all" is a checkmark in the toolbar, live only when something actually
has `has_draft`. A summary carries no version and publish needs the one it is
based on, so each document's detail is read immediately before its publish —
honest against a stale list, and no version-less backend path to maintain.
Failures are counted rather than swallowed: three of five fails says so and
names the three.

The health screen was fixed at 24 hours everywhere except its lists, which
were fixed at nothing: `failuresQueryOptions` read the newest 100 rows and
`HealthActivity` filtered them client-side, so on a busy engine the failures
list covered whatever few minutes 100 rows happened to span while the chart
beside it spanned a day — and pinning an older minute showed an empty card.
One `RangePicker` now sits on the Health heading and governs the whole block:
the tiles, the flow table, both charts and both lists. Presets are 1h / 6h /
24h / 7d — the collector prunes at `OBS_RETENTION_DAYS` (30), so a week is
behind the last one. The longer windows ask for coarser buckets, since a week
of minute rollups is ten thousand points nobody can see.
Failures get the escape hatch the runs already had: a pinned minute is asked
for with `since`/`until` rather than filtered out of what is held, and the
list itself is bound to the selected range. `RUN_DEPTH`/`EVENT_DEPTH` become
one `LIST_DEPTH`, which now buys coverage of the window on screen instead of
a fixed newest-N — narrowing the range is what makes the same rows reach the
whole of it. The "Failures (24h)" tile counts errors over the selected window
from the rollups the table is drawn from, so tile, column and chart agree.
The node-panel and edge trend curves get no picker. They are a Redis ring of
the last 120 values per message with no window to ask for, so hovering one
reveals what it actually shows — how many readings, and the span they cover.

The trend column carried `w-full`, which made it swallow every spare pixel:
the five columns beside it huddled in the left 40% with a dead gap before the
curve. It takes a bounded third now, so the auto layout spreads the rest over
the columns that have content to show, and a long flow name still widens its
own column into the card's scroll.
`si` reaches the rollup counts it was written for — 179240 executions reads as
"179k", and the failure badge and the failures tile follow. The plain window
leaves the small ones alone: 615 is still 615. The standing counts (nodes,
flows running, queue depth) stay exact, as does everything acted on digit by
digit.
The fade ran a full 40 of the 100-unit box. In a table cell three times the
width of a panel that washed out readings still worth seeing, so it is 25 —
a hint at the left end rather than a quarter of the series.

A name under every circle was most of what the graph drew, and none of it was
what someone looks at the brain for. Only the hovered or keyboard-focused
neuron names itself now — a failing one always does, since colour is never the
only carrier of a status. The label is absolute and the collide radius already
held that space, so revealing one moves nothing. Taking it out of flow also
fixed the off-centre edges: the node box was as wide as its widest label, so a
32px circle inside a 140px box sat 54px left of where the layout put it and
every edge aimed at the box rather than at the circle.
Neurons are filled discs rather than `bg-card` outlines, which were a hairline
against `--background` in light and close to nothing in dark. The fill is a
neutral `--muted-foreground` alpha and stays neutral: status still speaks only
through the border and the word beneath. Its lightness carries how recently the
open page saw that neuron publish — brightest just after it fires, decaying over
90s to a floor it never drops below, so a graph left open sorts itself into what
is busy and what is not. Edges do the same on their stroke. The signal is only
what this session has seen on the socket, so a fresh page starts everything at a
neutral middle rather than claiming a history it does not have. Both are CSS
transitions gated on `prefers-reduced-motion`, decayed out of and snapped into,
never the other way round.
`BrainEdge` now carries both circle radii and trims its path back to the rims,
with an arrowhead at the end it flows into. The barbs are two more segments of
the same stroked path rather than an SVG marker, so they dim with the line they
belong to. Neither trim reaches past the midpoint, so neurons closer together
than their radii still get a line pointing the right way.
`edge-pulse` reads its landing colour from `--edge-rest` instead of naming
`--muted-foreground`, so a selected edge — which rests in blue — decays into its
own colour instead of crossing to grey and snapping back at the end.
Obsidian's graph view is the reference for the first three: filled nodes sized
by degree, labels on a fade threshold with hover to recover them, and arrows as
an explicit affordance. The falloff-by-opacity encoding is the standard one in
the dynamic-graph literature.

The trend curve was two components: a rich one in the node panel and on edges,
and a bare line in the flow table. It is one `Sparkline` now, taking the colour
token, the height and whether the live dot and the readout show. The flow table
draws its rollup in the chart ramp with no dot — the rollups are polled, so the
right edge is the last completed slice rather than this instant — and keeps its
"nothing yet" state, as the panel keeps its three distinct silences.
All of them fade out to the left, through an SVG mask over the curve and its
area. The dot sits outside the mask: the newest reading is the one thing that
must stay solid.
`si` replaces `compact` and the ad-hoc "k" the uPlot axis carried. It prefixes
k/M/G and m/µ, but only outside 0.01–1000, where the plain number is already
the shortest thing to read and a written unit ("0.4 ms") stays honest. The
sparkline readout asks for four digits, so two neighbouring readings never
collapse into one string. Exact counts and anything the user acts on — a
payload, a form field, the edge inspector's value — are left unrounded.
`src/lib/utils.check.ts` asserts the rounding cases.
The activity table now spans its card: the flow name anchors the left, the four
numbers read down their own centre, and the trend takes the slack on the right.
Panel rhythm steps up one notch, gap-5 to gap-6 outside and gap-2 to gap-3
within a section.

The force layout settled roughly square, so in a wide band the graph sat as a
small island. Vertical centring now pulls nearly three times as hard as
horizontal and the seed sits on an ellipse, which settles at about 2.2:1
without stretching the circles or the edges.
The graph also slid in on load: the rebuild fit ran with a 300ms duration, so
React Flow animated the pan from its default viewport to the content. The fit
is instant now, and the canvas grows in from the centre with `scaleIn` once it
has a layout.
The pinned chart header said "Esc clears", which a phone cannot act on. It
carries the same "× Clear" button as the list header instead; Escape still
works.

The worker script is handed to the interpreter by path, so app/flow was
sys.path[0] for every node: `import queue` got the engine's. It now drops
its own directory before anything else imports, and runs with the
deployment's credentials scrubbed out of its environment.
Also: reload builds off the event loop, the pool wakes what is blocked on
it when it stops, a refused metrics flush is kept for the next one rather
than dropped, and the cascade events are paired through failures.

A node type can now say which outside thing its parameters point at, and
nodes sharing one — a broker topic, a URL, a bucket — are drawn as a single
neuron on a new /brain canvas. That makes the wiring which runs between
flows through a broker visible for the first time; no single flow's canvas
can show it. The key is read off stored parameters, so a credential
reference never reaches an id.
Layout is a d3 force simulation settled once and then frozen, lit by the
socket the editor already listens to: a neuron pulses when any node behind
it publishes, and its connections light as values pass.
Fixes the message pulse while here: interpolating the stroke against the
edge's `color-mix()` resting colour went through oklab and left the gamut,
which turned every pulse on both canvases fluorescent yellow.

A second bus subscriber folds executions, errors, timings and queue lag
into per-minute rollups, keeps failures with their traceback and an audit
trail of who published what, and records one row per cascade — manual runs
and previews included, under an id of their own that writes no idempotency
markers. Read back through /observability/*, which always answers 200 so a
degraded engine still renders its own health screen.
Also fixes two things found on the way: node-health alerts read `status`
where the engine publishes `health`, so a device dropping never alerted
anyone, and the Redis queue reported `parked: 0` whatever was held.

User code no longer execs in the engine. A pool of persistent worker
subprocesses speaks one JSON object per line; the controller installs a
proxy as the node's function, so every execution path funnels through it
and the pipeline is untouched. A crash costs one subprocess, a per-node
timeout is a kill, and cancelling from the canvas is that same kill.
The workers run a venv of the user's own on the data volume, filled from
a pip manifest versioned beside the flows. Applying it retires the

wall panel render that surface at its true pixel size and scale it to fit,
so a side panel opening changes only the scale — never the arrangement
being made. With the width and column count known the dot pitch is exact,
(width + gap) / columns by row height + gap, so a dot sits where every
widget corner snaps. The wall panel shows no dots.

One shell for both editors. Flows and dashboards each get a searchable
overview under the padded shell, their editors move to the full-bleed
canvas, and the floating chrome is shared: a title bar that only says
what you are looking at, and a bottom dock carrying everything else —
the flow bar's status, settings and Publish moved down there, the
add-flow button moved to the overview.
Dashboards gain the rest of M4's visualization work:
- widgets are picked by clicking them, with the header as the drag
handle so a slider still slides and a switch still flips while
editing; settings moved into the flows' SidePanel
- react-grid-layout for drag and edge-resize, so the stored x/y finally
mean something; a dashboard nobody arranged is shelf-packed once
- a per-dashboard grid size, so a panel can be matched to its screen
- the chart widget, drawn with uPlot: several messages on one axis, fed
from the stored history plus the live socket tail, coloured from the
new --chart-1..5 ramp
- /view/{name}: the URL a wall panel is pointed at — no sidebar, no
footer, no editing, and no editor code, since routes are split
- a widget wired to a payload type it cannot carry, or wired to nothing
at all, carries the same red dot a failing node does; the picker
records the type it bound and WidgetDef refuses a mismatch on save

Suggest a parameter's value from the nodes of the same type in every flow,
the way message names are already offered; secrets stay out of it. Explain
the cron fields, and derive the expression an interval asks for. Keep an
untouched function scaffold in step with the node's ports.

The floating bars used to make way for a side panel, which hid Publish
exactly when a node had just been edited. They keep their lane now and
the panel is inset out of it; the enlarged code editor stays a floating
surface between the two bars rather than covering them.
Shortcuts are one small registry (`lib/shortcuts.ts`): undo, redo, ⌘K,
copy, paste, and ⌘S — which publishes the flow, or applies the code when
the editor has focus. Copying carries a node's own source through
localStorage, so a paste works in another flow too.
A flow is now named where a node is, at the top of its panel and only
there, and both take effect on Confirm. Flow-level edits go through the
undo stack with everything else, clicking the canvas puts the flow panel
away, a failing node opens the logs filtered to its own traceback, and
the panel carries its test id on a phone as well.
