The rate the media dtypes could carry was one frame every second or two: each
was a file on the data volume, an event on the socket, and a request back for
the bytes. This closes both halves of that, and they are one feature.
`save_artifact(..., volatile=True)` writes to a `VolatileStore` — the same
content-addressed store, in `/dev/shm`, bounded by size with the oldest falling
out (`ARTIFACT_VOLATILE_BYTES`, 48 MB under the container's raised `shm_size`).
Nothing sweeps it: a frame nobody kept is not worth walking the store to find.
`ArtifactStore.path` falls through to it, which is what lets a volatile frame be
an ordinary reference everywhere else — the dtype check, a panel's digest scope,
`load_artifact` in a node, and the widget's own fetch all work on one unchanged.
`adopt` copies one into the store when a run records it, so "returned media is
kept, emitted media is not" stays true.
The bytes then go down the flows websocket as a length-prefixed binary frame,
sent just ahead of the `message_value` naming them, so a tile has the frame when
it hears the value moved. Nothing is pushed unasked: a client names the messages
it is drawing (`{"type":"media","names":[…]}`), a panel's list is intersected
with the scope it already had, and only the newest frame per name in a batch is
sent — a client that fell behind is not handed frames it would draw over. The
tunnel relays text only, so a screen reached through a portal falls back to
fetching, which is why the rate table now has two rows.
Around the edges: the remote worker's fetch cache is bounded at last
(`FLUKSIO_ARTIFACT_CACHE_BYTES`), since content addressing means nothing in it
ever expires and a media stream fills it with chunks nothing asks for twice; a
port carrying an image draws the frame in the node panel rather than only
saying `image/png · frame.png · 1.79kB`; and an edge chip says that much instead
of a line of hash. The media screenshot stops waiting for `networkidle` — a
camera is a socket that never goes quiet, which is the point of it.
A node setting's description comes off the backend JSON schema, so every
node type's panel still printed a paragraph under each field. It moves to
the field label, which is the change that makes the node panel read as a
list rather than a page.
Alerts, Modules and Remote access follow the same shape. A page keeps a
one-line description under its h1 — a page is arrived at rather than
scanned — and the rest goes behind the heading's tooltip.
Verified on the running stack: the tooltip opens on tap in the phone sheet
and on hover on the desktop panel.
The node, flow, widget and dashboard panels explained themselves in
paragraphs under every control. They now carry a caption and an info
tooltip, so a panel reads as a list of settings.
InfoTip, PanelSection and FieldLabel live beside PANEL_SECTION in
SidePanel.tsx, which the panels already share. InfoTip holds its own open
state because a Radix tooltip ignores a touch pointer, and below md the
whole panel is a full-screen sheet — hover-only help would leave a phone
with the caption and nothing else.
Dashboard/panels.tsx drops from 30 helper paragraphs to 5; the ones left
are empty states and status, not explanation. Em-dashes are out of the
user-facing strings, except where one separates the halves of a select
item.
Follows the portal: the noun is "instance" everywhere the app says it —
UI strings, CLI output, error details, docs and comments. The wire keys
(`instance_id`, `instance_token`) and the hub route this calls move with it.
An existing cloud.json is adopted rather than refused: without the key
alias the dataclass fails to parse, which the caller swallows and reads as
"never enrolled" instead of "reconnect".
`instance_key` on a node type becomes `target_key`. It means the outside
thing a node points at, which is a different sense of the word, and keeping
both would put two meanings of "instance" in one codebase.
**nginx served the bundle uncompressed and uncacheable.** The base image
ships gzip commented out and nothing set `Cache-Control`, so every load
carried the whole thing and every reload cost a 304 per asset. Measured on
the built image: the entry chunk 838 kB → 311 kB, the Monaco chunk 2.66 MB
→ 832 kB, and the ~50 content-hashed assets are now immutable for a year.
`index.html` is explicitly `no-cache`, since it is what names the rest.
**A widget that throws no longer blanks the screen.** There was one error
boundary in the app, on the root route, so anything that threw replaced
everything including the navigation — on `/view/{name}`, an unattended wall
panel with no way back. Each tile has its own boundary now, and the app
shell has one inside it so a screen that fails leaves the sidebar standing.
`react-error-boundary` was already a dependency and imported nowhere.
**`localStorage` cannot take the app down.** Reaching it raises where the
browser blocks site data, and `setItem` raises once the origin's quota is
full — which the flow editor's node clipboard, carrying whole Python
sources, can genuinely reach. Thrown from a key handler that escaped to
`window.onerror`, which the single root boundary then turned into a blank
page. `lib/safeStorage.ts` is the guarded pair the pre-paint theme script in
`index.html` was already using; a copy too large to store now says so.
Queries default to `staleTime: 5000` — below every poll interval on any
screen, so nothing polls less often than it did, but a route mounting twice
in a few seconds stops refetching everything it touches. Window-focus
refetching is off: the socket pushes what changes and a reconnect
invalidates what it feeds, so a focus event has nothing of its own to say.
Home alone reads about ten queries on every one of those.
Render cost, two that showed up in the audit:
- `LogsPanel` was rendered unconditionally by the dock and decided inside
itself whether to draw, so with the panel *shut* it still subscribed to
the log store and re-filtered five hundred lines per line a flow
published. It returns before any of that now.
- `HealthActivity` subscribed to the whole engine-event array and used one
number from it, so a flapping node re-rendered the component that draws
Home's two uPlot charts — each of which rebuilds its series on every
render by design. It subscribes to that number.
- the global search bucketed the index nine times per keystroke, once per
group. One pass, and each group offers at most twenty.
A three-node cascade publishes 13-16 events and each one crossed to the
event loop on its own. They are one `call_soon_threadsafe` now — whatever
was published between two turns of the loop goes over together — and every
subscriber still receives every event, oldest still dropped first when one
falls behind.
The socket end of the same path:
- **any frame from the client ended its stream.** `receive_text` was
awaited once, outside the loop, so a keepalive — or anything else a
client decided to say — satisfied it and was read as the client going
away. It is recreated per iteration; only a disconnect ends the stream.
- events go out in one frame per wave (`{"type": "batch", "events": [...]}`,
capped at 64), serialised once with orjson rather than per client with
the stdlib's `json.dumps` through `send_json`. The client unpacks a batch
and still understands single frames, so an older engine behind a newer
bundle keeps working.
- authenticating and building the snapshot happen on a thread. Both were on
the event loop: one is a database round trip, the other reads the whole
of state, per connect and again per `dashboard_changed` per panel.
`Pipeline.values()` — what that snapshot is — no longer SCANs the whole
Redis namespace. It scanned five bookkeeping keys for every message to find
the messages; `RedisState` keeps a set of the names beside them and answers
from it. Maintained wherever a message is written, so a seeded value or a
deleted flow keeps it exact.
On the client, while in the same file:
- a `node_health` event invalidates the flow's detail. The canvas draws
health from the server-derived `issues`, so a node going down or
recovering only showed on mount, navigation or a rebuild. The store had
a health map of its own that nothing ever read; it and `useNodeHealth`
are gone rather than wired up, since the server's view is the one the
canvas already uses.
- a reconnect invalidates the five key families this socket feeds instead
of the entire cache, and the backoff is jittered. The usual reason a
socket dropped is the engine restarting, so every tab and every wall
panel refetched everything, together, at the moment it was least able to
answer.
- a frame that will not parse costs the frame, not the connection. It was
the one unguarded `JSON.parse` in the app; an exception there escaped to
`window.onerror` and left whatever it had already applied behind.
`GET /api/v1/search/` hands the client one flat index of everything worth
jumping to — flows and the nodes inside them, dashboards and the widgets on
them, panels, secrets, modules, workers and alert channels — and cmdk matches
it in the browser, so results narrow while typing without a round trip per
keystroke. A node hit is the one thing no list endpoint could answer: it opens
its flow with that node in focus.
The panel is reached from **Search** above Documentation in the sidebar, or
⌘K anywhere. The flow canvas palette moves to ⌘P, being the narrower of the two.
The panels dialog gains an address (`/dashboards?panels`) so a panel hit has
somewhere to land, and the sidebar logo gets `shrink-0`: the rail's width
animates while the logo is already back, and a flex item short of room is
squeezed rather than clipped.
Copies index/frontend's FluksioLoader component and its
`.fluksio-loader-line` rule into the app (the shadcn duplication model, so
the CSS travels with the component) and swaps every Loader2 pending state
over: the router's pending screen, the flow dock's Run and Publish, the
dashboard editor's Publish, the overview toolbar's Publish-all and
LoadingButton. One loading mark across both shells.
The force simulation settles on arbitrary floats, and a neuron on a half pixel
has its ring, its gap and its disc rounded one edge at a time — which on the
smallest ones is a visibly off-centre ring. The size is already whole, so the
position was the last fractional term.
The console panel lived inside the bar, so its centring translate and its
backdrop filter were both nested inside the bar's own — a half-pixel offset
under a blurred layer, which is what Gecko was rasterising the text through.
Panels and bar are siblings in one column now.
That column is also what the issues list needed: it was a popover anchored to
its trigger, opaque where the console is frosted and landing on top of it when
both were open. It is the same panel now, the same width, in the same row.
A bool was excluded from the history as "not a measurement", so a true/false
port had no curve in the node panel and none on an edge — only the word. It is
recorded as 0/1 now and drawn as steps, since a bezier through two states
slopes through readings that never happened. The axis is pinned to 0..1, so a
flag that was never on sits at the floor rather than mid-box.
`resources` was reachable from the SDK and the API and nowhere else, and
`node_queued` was published to nothing at all — so a node waiting for a machine
looked exactly like a node that had hung, which is the failure the event was
added for.
The node panel gets a Resources section: a size by name, the numbers for a node
that wants its own, and how long it is expected to take. Picking a flavor drops
the numbers, because saying both is two answers and the engine refuses it.
A queued node draws a neutral dot rather than one of the three status colours —
it is not running, it did not go well, and it did not go wrong; it is idle with
a reason, which the tooltip gives.
And a Workers screen, which is the first UI for any of this: every machine the
engine can reach with what is free of each, what is attached, what a cluster
has been asked for, and the sizes, editable. `fluksio status` grew a line of
the same.
The demo's training node already preferred a GPU worker, which was exactly the
declaration that used to be dropped, so it now says how much of that machine it
takes as well.
A port may now declare `image`, `audio` or `video`. Each is the artifact
reference the engine already had, narrowed by the `media_type` on it, so a
speech recogniser declares what it eats rather than taking any bytes at all and
finding out. Bytes still never travel as a message and nothing on the wire
stops being JSON: a camera publishes one reference per frame, a microphone one
per chunk, and a reference may carry a `meta` dict nothing here interprets.
Streaming media is therefore an ordinary streaming port — with one change to
what that means. An emission used to journal an item with no payload, so
downstream read whatever was current when the item was claimed; a consumer
slower than its producer saw only the newest chunk and the ones between were
lost. That is right for a training curve and wrong for a second of speech, so
an emission now journals a `kind="emission"` item carrying its values, and the
executor hands them to the nodes reading that message instead of writing them
to state again. The value in state stays the latest, which is what everything
else reads, and the wave is filtered by what actually changed rather than
walking everything reachable. No queue serialization change — the existing
`outputs` field carries it.
Continuous media makes the store's missing GC a real problem, so this closes
it: `sweep_artifacts` runs hourly, keeps every digest a `run_artifact` row
records or a live message holds, spares anything written in the last hour, and
stands aside entirely while a run is in flight, since a node may store a
checkpoint long before it returns the reference to it. That also collects the
orphans a deleted flow has always left behind. `ARTIFACT_GC_INTERVAL_S=0` turns
it off.
Around the edges: `GET /artifacts/{digest}` serves the media type the caller
passes and answers ranged requests, so a browser plays a clip rather than
downloading it; `PUT` spools to disk instead of holding the whole body in
memory, as does `save_artifact` given a path; a Media widget draws whatever its
message points at, and a wall panel may fetch the bytes its own tiles are
showing and nothing else; and a connector gets `save_artifact`, for a device
whose readings are bytes.
What this cannot do is live video: a frame every second or two is a glance, and
the honest answer above that is the camera's own stream, which the widget takes
as a URL and the browser plays from source.
The canvas placed nodes with dagre, which orders nodes but knows nothing
about ports: an edge leaves a particular handle and lands on a particular
one, so two producers feeding a consumer in the other order crossed just
before they landed however well the nodes were arranged. The graph was not
a multigraph either, so two messages between one pair of nodes collapsed
into one before crossings were counted, and the endpoint labels were laid
out as 220-wide cards with every handle stacked on a single pixel.
ELK's layered algorithm replaces it. Every declared port is handed to it as
a fixed point on the node's rim, at the fraction `portFraction` puts the
handle at — which the node components now render from the same function —
so what the crossing count is minimised over is what ends up on the screen.
Measured on this installation's flows, with the labels included: `home`
goes from 51 crossings to 6 across and 70 to 29 down, `demo_training` 27 to
5 and 59 to 32, and every graph is the same size or smaller.
The engine answers asynchronously and is a chunk of its own, so positions
became state: the canvas draws nothing until the first layout lands, and an
edit keeps the arrangement it had rather than flashing through the corner.
The entry chunk is untouched and the flow route's own chunk came down 167
to 121 kB, since dagre used to be in it.
Two things the crossings made worse come with it. A hovered edge resolves
to full strength so one line can be followed through a busy rank, and a
feedback edge — one whose target the layout put behind its source — swings
out into a lane beside the graph instead of being drawn through everything
between its ends, which is what "House history" was reported for.
Clearing a node's last error on the engine published nothing, so a second
browser kept the marker until its next snapshot. One event carries the
qualified node; the receiving client drops the marker without refetching.
The popover showed a non-numeric value twice: only numbers are recorded,
so MessageSparkline fell through to a collapsed ValuePreview and the
inspector rendered its own expanded one below it.
`ADVISORY_ISSUES` moves next to `ValidationIssue` in pipeline.py, and the
model derives an `advisory` flag from its own code, so the distinction the
engine already made ships to the client instead of being re-guessed there.
The dock keeps its summary in `--destructive` only when a real fault is
among the issues and paints an advisory row `--muted-foreground`; the
canvas leaves advisories off a node's dot and border entirely, since node
status has three colours and no warning tier.
biome checks the generated `openapi.json`, which nothing formats since the
SDK script dropped its format pass — ignore it like the other generated
files.
A cache hit still replays no emissions — those values were the story of an
execution that is not happening — but the run they were recorded in is now
written on the row (`run_node.cached_from`), and the metrics endpoints read the
series back from there. So a reused run answers `run.metrics("train.loss")`
with the same points the run that trained did, rather than looking like a run
that produced no numbers at all. Pointed at rather than copied: a sweep of 500
reusing one frozen node would otherwise duplicate its curve 500 times.
That needed the cross-flow restore fixed first. The cache key has no flow in
it while the stored outputs are named for the flow that produced them, so
`quick.prepare` getting a hit from `train` wrote `train.dataset` into `quick`'s
state and the next node was called without its argument. One rule now covers
both halves: `requalify` reads a name owned by one flow as the same name in
another, applied to the restored outputs, to the node id behind the pointer,
and to the series names on the way out. Reuse across flows is kept.
Also: `@run:<id>.<output>` and a bare `sha256:` digest resolve on every input,
not only artifacts. Chaining a run's json config into the next one from a shell
meant pasting the whole object inline, and the CLI could not even send the
spelling — `_coerce` died in `json.loads` before the engine saw it. Both
spellings are reserved on every input now, `str` included, and `_from_run`
returns whatever the run's result holds rather than only a reference.
Four things the python SDK turned up, each fixed where every client sees it.
A key no port declares is now an error rather than a silent drop, on the
return, the yield and the emit alike — the contract the docs already stated.
The SDK reads literal yields at sync time, so a typo fails before anything
runs, and an emission of one fails the call rather than being logged where
nobody looks.
NaN and infinity are refused at the port. JSON cannot spell either, so one
that travelled came back as a 500, a socket frame that stopped the canvas, or
a metric batch the database dropped whole.
An artifact input takes `@run:<id>.<output>` or a bare digest, resolved on the
engine — so the CLI, the run dialog and a python caller mean the same thing,
and a sweep can pass one at all.
Node timeouts are off by default. The clock measured silence, which a training
node is full of, and remote workers had already stopped enforcing it — their
heartbeat reset it. Now a heartbeat proves the agent rather than the node,
ninety seconds of nothing fails the call either way, and the engine touches
work it is still running so a long node is not redelivered at sixty seconds.
A dashboard is a wall panel somebody hangs in their own hallway, so it
now wears what they choose: a look, and a palette of their own colours.
Two complete component sets live under `Dashboard/ui/` — `glass`
(translucent panes over a slowly moving ground) and `material` (Material
3 tonal cards) — behind one prop contract. Every control's state,
keyboard and `aria-` live in `ui/core` and are shared, so the two sets
are the same dashboard drawn twice rather than two products: a set only
decides what a control looks like while doing it.
Four settings join the channel, each drivable by a flow like any other:
`look`, `palette`, `background` and `touch`. A palette is an ordered list
of hex colours — background, surface, primary, accent, text, then more
chart colours — pasted from a coolors.co link or typed, written onto the
canvas as the token variables everything already reads. Trailing roles
are derived, so three colours are a whole dashboard, and derived text is
held to AA rather than trusted (`theme.check.ts` measures it). A palette
also decides light or dark, since its first colour is the ground.
Widgets are measured against their own tile with container queries rather
than against the viewport, animate through `motion`, and can be drawn
without their title. The three reworks:
- a bar draws a row per reading, up to eight, each in the dashboard's own
data colours and each able to carry its own scale — replacing readings
nested in one fill, which could only ever share one colour and stop at
three. Documents written the old way are read as rows.
- a chart's range picker moved to a column down its right-hand edge, which
gives the plot back a whole row of a short tile.
- the colour wheel became a disc: hue is the angle and saturation the
distance from the middle, so a colour is one gesture rather than three,
with brightness on a slider beside it.
`index.css` and `lib/motion.ts` are untouched — the dashboard overrides
token *values* on its canvas, never the blocks the two repos share.
A data scientist keeps their code where it is and decorates it: `@node`
declares a function's ports beside the function, `Flow(name, nodes=[...])`
says which of them make a flow, and `use(fn, wire=..., **settings)` rebinds
one for a single flow. `fluksio sync` uploads the document plus a generated
import shim per node, so the store still holds a complete, runnable,
git-versioned definition while the code it imports stays theirs.
`fluksio login|run|runs` and `flow.submit().wait()` are the client half, over
the run endpoints that already existed. Runs record the user repository's
commit beside the store's, so "what code produced this number" is answerable
on the side that now holds the code.
- `fluksio/sdk/`: ports, decorators, the flow builder and its checks, the shim
generator, an HTTP client and sync. Standard library only at import, so
`from fluksio import node` in a training script pulls in no engine.
- `FlowDef.origin` marks a flow code-defined; `Run.origin_commit` carries the
repository's commit; `POST /modules/refresh` retires the workers without an
install, which every sync calls — a worker holds the imported package in
memory, so an edit to it is invisible until the process goes.
- The canvas shows a generated body read-only and names the repository to edit
instead; a body edited there stops the next sync rather than being discarded.
- The worker's reporter carries inert `Port`, `node`, `use` and `Flow`, since
the shim imports a module whose first line declares them.
- `examples/myresearch` is the worked example, `make sync-example` uploads it.
React Flow stamps `colorMode` on its wrapper as a class and defaults it to
`light`. The app's own token scopes are named `.light` / `.dark` — the classes
that let a dashboard be forced to one theme inside a shell on the other — so
every canvas was silently redeclaring the light palette on its own subtree:
white node cards and a white canvas in dark mode, with the inherited
`--foreground` text still near-white and therefore invisible. Home's neurons
had the same fault, drawn with white ring gaps and the light `--primary`.
The comment said the canvas follows the theme without a `colorMode` prop. It
does not — React Flow stamps that prop on the wrapper as a class and defaults
it to `light`, which collided with the app's own `.light` token scope and
re-themed the whole canvas. The prop landed in 4e1898a; this is its reason.
Reserving a slot for all three status controls left 72px for a node's title,
against about 140px before. Only the stop button and the dot come and go on
their own; the traceback button appears when a node newly fails and goes when
someone acknowledges it, which is a thing to notice rather than a flicker. It
goes back in the row, and the title gets 106px.
- A node's height follows the ports on its busiest side. It is a function of
the document, so `layoutGraph` reserves exactly what is drawn and nothing
measured is fed back into the layout.
- The three status controls now sit in slots that are there whether the
control is or not. A node running many times a second mounted and unmounted
the stop button on every execution, resizing the card each time.
- A port bound to another flow's message is drawn as a label, naming the node
at the far end and its type. Only the opposite direction was answered
before. The scan behind both is now cached on the store's commit counter
rather than reading every flow per request.
`--xy-connectionline-stroke` was never set, so the line dragged between two
ports took xyflow's `#b1b1b7` literal in both themes and was a hair thinner
than the edge it became. It is a selection-like state, so it takes `--primary`
and the canvas's own edge width.
--brain-decay 90s -> 150s and the wire floor 32% -> 16%, so a quiet
connection dims further and takes longer doing it. The pulse ring's inset
and band become custom properties (defaults unchanged for the editor's
card), and the neuron passes its own ring and gap so the arc runs the full
width of the gap; it moves after the disc, which otherwise paints over it.
`flow.css` set `--xy-background-pattern-dots-color`, which nothing reads:
xyflow's `.react-flow__background-pattern.dots` reads
`--xy-background-pattern-color` and only falls back to the `-dots-color-default`
literal. The grid was therefore pinned to `#91919a` in both themes — and with no
`colorMode` prop the `.react-flow.dark` default never applies either, so it read
as a light-mode grid on a dark canvas.
- Home puts the dashboards beside the flows: two equal-height columns,
capped and scrollable, most recently worked on first. Each tile is a
schematic footprint built from the stored widget placements.
- Flows and dashboards can be picked by long press or ctrl-click; the
create button becomes a trash and one dialog covers the batch.
- The offline banner is drawn on the body so it centres on the viewport,
and the live socket now releases the offline latch a stray 503 set.
- A boot spinner before React's first commit, a router pending screen for
code-split pages, and skeletons where an empty list used to flash.
A node's error cleared the moment it ran again, so a failure that genuinely
fired an alert could leave no trace on the canvas by the time anyone looked.
The engine records it now — on the node's status, so it survives a reload and
every client agrees — and reading the traceback is what clears it. The seam is
the event bus, which is where every failing path already meets: a queued live
run, an explicit run, a preview, and a single triggered node all publish
`node_error`, while the controller's own observer would have seen only one of
them.
That was half the confusion. The other half: clicking a failed neuron on Home
often landed on a flow where everything looked fine. Nodes merge into one
neuron by instance key — every InfluxDB node pointing at the same bucket is one
neuron — and the click went to whichever flow contributed a member first, not
the one that failed. It now goes to the failing member and selects it, and the
canvas marks a failing node rather than leaving it to the dot alone.
The inject node emitted one payload to every port it declared, whatever their
types, so an inject on a bool port carrying the text "true" raised at publish
time. Each port gets its own field now, typed and parsed by that port's dtype,
and remembers what it last sent. A port that is renamed carries its value with
it; one that is removed takes its value with it. An inject written before this
keeps emitting exactly what it did.
The derived-cron chip also appeared on the delay node, where `interval` is a
rate limit and a schedule derived from it means nothing.
Three things moved the viewport independently — the shape-fit effect, focusNode,
and React Flow's own fitView prop — so a fourth for "centre the node I just
selected" would have been a fourth party to the argument. There is one effect
now, and which branch it takes is decided by what changed rather than by what is
true: selecting a node brings that node into the lane the panel leaves, and
every other change — new wiring, a new endpoint, a panel opening — re-fits the
whole flow into the same lane. A selection centres once, so the port edits that
follow re-fit around it, which is what makes a new edge's far end visible.
The refit triggers on the edge count, not the bindings key: that key changes on
every keystroke in a message-name field, and refitting per character is not what
"an edge was created" means.
renderedNodes overwrote xyflow's own `selected` flag, so a box-selection of
several nodes was invisible even though delete and copy acted on all of them.
The logs panel was a popover anchored on its own button, which is why it sat off
centre, hugged the button and closed on any outside click. It is a plain surface
above the dock now, and the button is stateful. Escape still closes it.
Expanding a node's editor gives the panel the whole inset and puts the code on
the left with the settings beside it, while the toolbar and the flow name
translate off screen. Narrowing the window past `md` gives the room back — the
sheet it becomes has no second column to hold.
The zoom buttons are gone: there is a mouse, or there is a pinch.
Three things the security pass on the portal pairing turned up. The first two
were already true of a screen on the local network; what changed is that a
panel credential is now presentable from the internet, which is what makes
them worth closing rather than recording.
The artifact endpoint authenticates for itself, because a worker's credential
has to open it and that token is no use anywhere else. It resolved the caller
without handing over the request, so the one credential that is scoped by
route was judged by no route at all — a panel could read and write the store
as whoever approved it. It passes the request it already holds now.
The websocket has no route to judge either, and there the bound has to be on
what is sent: a panel is given the values its own dashboards draw and nothing
else — no node status, no logs, no shape of the graph. The keys stay in the
message, emptied, because a screen on a wall runs the bundle it was paired
with. `messages_for` reads that set off the published dashboards, and is the
walk the `/messages/` allowlist has wanted for a while.
And locality is no longer a header anyone can type. The marker the connector
stamps is a value minted per process, so reaching this API directly cannot buy
a device the credential meant for one that cannot reach it at all.
A sweep against the code. Removed as resolved: the worker pool's `_running`
is keyed by (run, node) now, `WorkItem.kind` documents only the three kinds
that exist, `routeTree.gen.ts` matches its generator, and the host's Node is
well past the version the Vite 7 note was about. Removed as disproved: the
collector's redelivery branch is reachable — Redis reclaims an entry this
process is still running.
Corrected: the demo places six of the fifteen node types, not thirteen — the
count was the widget types. Narrowed to what is left: the header/config sync
now covers settings but only on an untouched scaffold and only one way; a
declared flow input is what the dashboard-input node asked for; the flow
boundary already refits the canvas where node ports do not.
The Playwright hazard is not resolved — both names still resolve to
production — and the fix as written is incomplete: `VITE_API_URL` has to be
overridden to `http://` or every setup call fails the TLS handshake.
Also: one `asText` instead of two, and the queue docstring no longer refers
to a node item that never existed.
A flow's inputs are the messages it takes from outside — a dashboard control,
a run, the API — and its outputs are what a batch run reports. Both existed in
the document and in the engine, and neither had any UI: the values looked
hard-coded on the canvas and the Run button always used the declared defaults.
The canvas now draws each as a labelled endpoint, the way it already draws a
dashboard tile or another flow, skipping an input something else already
accounts for. The flow panel edits them — mode, name, type, starting value,
and for a live flow the value it currently holds with a way to put a new one
in. Pressing Run on a batch flow asks for its parameters first.
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.
A panel is one screen and the ordered set of whole dashboards it shows, so a
hallway tablet and a workshop tablet carry different sets without either
dashboard knowing about the other. More than one and the device draws a rail
to switch between them — the same rail the editor puts on screen, because the
wall has it and it takes room off the canvas.
A screen has no keyboard, so it pairs rather than logs in: it shows a
six-character code, somebody approves it against a panel from the dashboards
overview, and the credential that mints reaches that panel's published
dashboards and the message endpoints its widgets speak, and nothing else.
Deleting the panel revokes it.
Closes the per-device view and the kiosk credential; supersedes the
multi-page/multi-section UI, since a page is now a dashboard of its own.
The arc was one-shot feedback for an emit, so a node that works for minutes
showed nothing after the first half second. A run now holds the ring on the
node and laps it until the node stops.
The JSON preview capped a ScrollArea rather than the pre inside it. Radix
sizes that viewport in percent, which resolves to the content's own height
against a box carrying only a max-height, so a list or dict of any length
spilled out of the node panel and the edge popover and painted over the
sections below.
React Flow's selection changes had nowhere to go: the canvas passed
edges but no onEdgesChange, so no edge ever carried .selected and both
the selected-edge stroke and its rest colour were unreachable. The edges
are derived from the bindings, so the selected ids are held on their own
and marked on after the layout has had the array — a rebuild cannot drop
the selection, and selecting cannot make the graph lay itself out again.
The socket belonged to whichever hook instance ran its effect first. Passive
effects run children before parents, so on Home that was the brain graph rather
than the shell: navigating to a sibling route unmounted the graph, which closed
the socket, while the shell kept the reference count above zero. From there the
page was deaf for the rest of its life, with nothing left to reconnect it.
A module-level connection with a real refcount replaces it — connect on the
first subscriber, disconnect on the last — and the hook is a thin subscription
with the same signature, correct under StrictMode's mount/unmount/mount.
A 1008 now reconnects instead of returning silently: the token is read afresh
per attempt, and three consecutive rejections fall through to the caller's auth
handler so a revoked session surfaces rather than spins.
The snapshot's emit counts are read into a store of their own, apart from the
live count, so a graph that connects into a busy engine is drawn as busy without
every neuron claiming it just fired. The neuron and edge pulses now key off a
change seen while they were mounted, so returning to Home no longer replays
every emission of the session.
Home gets a live indicator for the case none of this can fix: quiet while the
socket is up, and named in words when it is down, since HTTP polling keeps the
rest of the page looking current.
The ring hung off the node itself, and `inset` on an absolute child
resolves against the padding box — so on the brain's thick status ring it
landed inside the outer edge and painted over the status the ring carries.
Both node shapes now hang it off a border-less wrapper, where the same
offsets clear the rim whatever border the node draws (measured: 4px on all
four sides, on a 1px card border and a 7px neuron ring alike).
The shape is a conic-gradient arc masked to the padding band, running one
lap in `--duration-pulse` and going out on the way past.
Note: BrainNode.tsx also carries an unrelated in-flight change from a
concurrent session (the `seen` ref gating the pulse on a real emit); the
two could not be separated in one file.
A port with `stream` set publishes repeatedly during one execution, and
until now nothing on the canvas said so. `deriveEdges` carries the flag
from the producing `MessageSpec` onto the edge, `LiveEdge` turns it into
an `edge-stream` class, and the class draws a dashed stroke whose offset
marches toward the target. The pulse still lands on top: both animations
share one declaration when a value arrives on a streaming edge.
The editor's mount-time fitView animated from React Flow's default viewport,
which read as the graph swiping in from the corner on every open. The first
fit is instant now, later ones stay animated, and a scaleIn wrapper gives the
same entrance the brain view has — with a re-measure on completion so the
handle bounds are not stored mid-scale.
Home only renders the brain band once some flow has nodes, so a fresh install
no longer reserves a screenful of empty space above the flows card.
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.
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.
