The entry is 798 kB (259 kB gzipped) instead of 927 kB (298 kB). Signup's
`export default` kept it unsplit, and login, recover and reset-password left a
bare `z.object(...)` statement in their route stubs (reset-password also read
its search through Zod), which held all of Zod and react-hook-form in the entry.
The schemas are factories now, reset-password validates its search by hand.
The shell routes keep their component in the entry on purpose
(`codeSplitGroupings: []`, no `export default`): splitting them out measured
about 60 chunks per signed-in screen and a slower flow list. The Zod
`@__PURE__` comment warning is filtered and the chunk limit is 850 kB, each with
a comment saying why.
At 4x CPU on slow 4G the signed-in screens load 5 to 9% sooner, view 6%; login
13% later (the form chunk is one more hop). On a LAN they are within noise.
Node source (Python) and the JSON dialog share one CodeMirror editor with
find and replace, autocomplete, folding, indent guides, comment toggle and a
JSON lint, themed from the CSS tokens so light and dark follow the .dark class
without a second palette. Programmatic value changes no longer fire onChange,
blur ignores focus moving into the find bar, readOnly keeps selection and copy.
The editor chunk is 470 kB (157 kB gzipped) against 2.7 MB (704 kB) for Monaco,
which also pulled in a 1.2 MB JSON mode, two workers and a font. At 4x CPU on
slow 4G a node panel is ready in 5.7 s instead of 10.8 s, the JSON dialog in
1.5 s instead of 6.7 s. Typing without a key delay keeps every character.
monaco-editor, @monaco-editor/react and the dompurify override are removed.
Specs: typed code reaches the node source, a JSON setting saves only text that
parses. Docs name Tab and Ctrl-M.
The channel sends through the Bot API with httpx only: HTML with escaped text,
cut to fit a message, silent for a warning, a short 429 waited out once, and
errors that say what to do about a blocked bot, a lost chat or a bad token and
never quote the request URL. The bot token is a stored secret: saving a
channel refuses a literal one, the card's "Store token" writes the secret and
a reference, and no endpoint returns it.
A chat id is never typed. Connect starts a ten minute code, and the chat that
sends `/start <code>` back through the bot is the one connected, so it is a
chat somebody opened a link for. The engine fetches updates only while a code
is waiting (no standing poll, no webhook, no inbound address) and ignores
everything else without a reply. Connect needs a saved form, and the form
takes the connected chat in without touching what was typed since.
The token is part of every Bot API URL, so the httpx logger gets the same
filter the request lines have, which now also masks an httpx.URL argument.
Any signed-in account could save an ntfy channel with its own `server` and a
`{"$secret": ...}` token and press Test, which sent the stored secret to that
host. The config GET/PUT, the test route and the global search's alert entries
now answer to superusers, like /secrets. The webpush key and subscribe routes
stay open to every account, and the Alerts page shows a non-superuser only the
button for its own browser. The events table in the docs gains run_finished.
/search gains a `setting` category, `<node>.<setting>` under its flow with the
node type and the value in a new `detail` field, so Ctrl-K finds which node
uses a broker or a timeout and opens the node. `setting_text` is the one place
that decides what may be said: a reference to a stored secret shows its name
(to superusers only, as the secrets list does), a plain value in an `x-secret`
field or under a key like password, token or api_key is masked and never
indexed, nested credentials in headers or query are masked, long values are
clipped. The global search ranks what contains the query as typed ahead of
loose spellings before it caps a group, which long setting values would
otherwise have crowded out.
An input row now starts from its message and ends as the argument the code
takes it as ("as prompt"); an output keeps its key on top and the message
below. The name the code uses is muted text with a pencil while it follows the
message's last segment, and a field only when it differs. Device Follows ports
get the same order (message, then the port driven). A list port's item type
moves to the second row so it no longer squeezes the name, two ports deriving
one name get a warning, and the rows rebuilt use 44px touch targets on phones.
The stored node spec is unchanged.
save_artifact/load_artifact outside a node use the worker's own store code in
$FLUKSIO_ARTIFACT_DIR or <tmp>/fluksio-artifacts, so a node can be called by
hand. --follow prints status changes and each node's resource wait; the
placer's waiting snapshot now carries the run. fluksio cancel <run>...
- InputInspector hangs off the label's element and EdgeInspector off a point in flow coordinates (ViewportPortal), both re-measured every frame while open and hidden once the anchor leaves the view. A label that leaves the canvas closes its popover.
- Dock: below md a bar across the width, flush with the bottom edge (bg-card, top border, safe-area inset, no shadow); from md the floating pill as before. The flow dock drops the Run caption and the dashboard editor clears the bar with its own padding, so the editing state fits one row from 360px.
- Tests: the search spec checks the popover rides along with a pan; the mobile spec checks both docks are a full-width bar flush with the bottom.
- LiveEdge: a value inside a running pulse restarts the animation by hand, since the class is already on and would show nothing.
- Dock, FlowDock: the bar is centred on left-1/2, where a shrink-wrapped box gets only the half of the screen to the right and wrapped into a 195px pill. w-max with the viewport cap keeps one row whenever the buttons fit. The dashboard editor's dock had the same squeeze.
- FlowEditor: arriving on an input drawn on the canvas centres its label and opens the label popover once the view is fit, as clicking it does. An input the canvas does not draw still opens the flow settings.
- Tests: the phone dock may not be confined to half the screen; the search spec reads the popover first and reaches the settings through its pencil.
Per the Microcopy rule: size and duration errors, the flavor errors, run
parameter errors, the Resources field descriptions, 401/409/400 details,
secret errors, the websocket node description and its on_connect setting.
The generated client follows.
The phone header carries a single speech bubble: Control on Home, the
assistant elsewhere. Chips above the input offer the user's most sent
messages per tab, then starters; a tap or a double-click on a sent or
heard message fills the input without sending.
POST/GET /flows/{name}/nodes/{id}/train submit wren_train on the node's
targets, examples and tests and read its latest run (run.for_node,
cause "train"); "Use this model" writes `model` into the draft.
run_turn takes its tools, system prompt and tool caller; the chat passes the
MCP tools as before. The assistant node offers one tool per wired target,
reads its other inputs as context, streams its reply a sentence at a time,
warms the provider on `listening` and says so when the provider is not there.
Completions share the per-server HTTP client. wren replies when nothing reads
`unhandled`, stt shows a note when nothing was heard. /ai/control lists one
conversation per entry node with the messages to watch.
- `stt`: one realtime transcription session per utterance on the speech
server's url, opened at `listening` true or the first chunk, committed at
false; a whole clip goes to /v1/audio/transcriptions. Returns at once and
publishes `partial` and `text` when the server answers.
- `tts`: one /v1/audio/speech call per sentence, cached by voice and text in
node state; a reference is marked `append` while earlier ones still play.
- wren: `reply` says what was applied, `unhandled` carries the prompt when
nothing was. The install hint names the git pin (PyPI's `wren` is another
package).
- ai/client: transcribe, speak and transcribe_stream beside stream_completion.
- A device socket publishes scalar `in` ports as {"type": "publish"} text,
in order with its binary frames.
- Pipeline.publish walks only what its values reach: a node downstream of a
consumer that published nothing no longer runs again (wren re-acted on
every microphone chunk).
- `service` node type: command, port, worker label, health path, env and
weights (an artifact digest the worker fetches as {weights}). Its flow
starts it; it restarts with backoff, reads degraded while starting or
without a worker and down after three starts that never got healthy, and
publishes http://<worker>:<port> once /health answers 200, "" when it ends.
- Worker protocol 3: a `serve` call, every call in its own process group,
killed when the engine ends the call, the socket drops or the agent gets
SIGTERM. `--service-host` overrides the address the engine sees.
- Services and compiles take no `--parallel` slot, and a flow's detail is
built off the event loop, so a save no longer stalls the engine.
C4: a device's `viewers` (superusers by default, or members) covers the
image and video messages its ports publish. Anyone else gets none of their
values on the socket, in the catalogue or a flow's state, 403 for their
history, for the frames they hold (the last 8 included) and for TURN
credentials, no bytes when asking for them, and `bye: forbidden` for a live
view. A device credential stays bounded by its dashboards. The device page
sets it in its Camera section, and a tile the viewer may not see says
"No access to this camera" and asks the camera for nothing.
C3:
- A volatile upload is held to MAX_FRAME_BYTES (4 MiB, 413 above it, read
without extra copies), and so is a frame on a device's socket.
- A frame the engine holds in memory is written to the ring directory
before a local worker is handed it, so load_artifact finds it.
- A socket the bus dropped events for catches up with a snapshot, demand
included, and a device's credential is checked again per frame, cached by
the flow store revision and its nonce, so a lost event never keeps an
unpaired device's frames coming.
- A report is at most 64 KB once its named config_schemas are put in place.
- A device away for 60 s has its true bool messages set to false.
- Refused frames are logged by fixed keys, a frame is named after its
message, `fluksio serve` waits 5 s for open connections, a tile with a
stream URL creates no demand, the 8-name cap keeps the newest names.
- Every container's log rotates (json-file, 3 x 10 MB).
A device reporting a `live` port streams its camera to the browser's own
RTCPeerConnection. The flows socket carries the signalling as text, so it
crosses the portal: `live` messages on a person's socket, `signal` on a
device's (start, sdp, candidate, bye, busy). The server routes by session,
holds a device to two viewers, ends a session when either socket closes or
no answer comes within 10 s, and gives each socket an outbox of its own
that ends a session rather than drop a message. TURN credentials are
minted per session in coturn's REST scheme (STUN_URLS, TURN_URLS,
TURN_SECRET), the viewer's with the device's offer; GET /devices/{id}/ice
hands them out too. The tunnel keeps a stream's early frames instead of
dropping them past eight and forgets them when the stream or link goes.
A media tile on a device's camera, and the Devices tab's preview, play
live when tapped, pause frames meanwhile, and fall back to frames with a
short note on busy, failure or no picture within 10 s. coturn is an
optional compose service behind the `turn` profile.
- Volatile frames are held in memory with a byte-bounded queue instead of
the /dev/shm ring scanned on every put; workers keep writing to the
directory, which is trimmed on a timer. A volatile upload no longer spools
to disk. ARTIFACT_VOLATILE_BYTES=0 turns the ring off.
- A device sends camera frames as binary messages on its socket, held and
published in one step and credited to its device node; refused frames are
logged and dropped. Its snapshot carries demand and the uplink (binary, or
http through the portal).
- One demand registry for every socket's wanted media, the tunnel's
included, plus what running flows read, mapped onto on-demand ports and
published as device_demand; at most 8 media names per socket.
- Per-message deflate off in serve and dev; a device may fetch the last 8
digests of a message; published dashboards cached per store revision; a
revoked device socket is closed with 1008.
- Media tiles want bytes only while on screen; the Devices tab previews a
wired camera; the device node warns when a flow reads an on-demand port.
- POST /devices/pair answers a 2-character `check`, listed by /devices/pending
and shown beside each waiting entry; five codes a minute per address, and at
50 waiting the oldest gives way instead of a 429
- portal-minted device tokens are asked for with the device's nonce (`pnc`) and
held against it, so unpair and delete revoke them; one without `pnc` stands
only while the nonce is 0
- a device credential acts as the device (`device_principal`), not as the
approving superuser, so deleting that account unpairs nothing
- the report is validated port by port: unknown enum values read as `unknown`,
unreadable ports and sections are left out and logged, `config` may name an
entry of `config_schemas`; 422 only for no schema 1 or no object
- devices.json is parsed once per change (cached by stat), delete drops the
report and keeps the nonce, a busy recheck runs in the background
- scope and io only from enabled flows (start/stop tells the devices), a port
bound twice gives one io row
- the Devices tab's saves cancel and hold back device refetches until settled
A device reports its board, screen, camera and ports from its own
credential (16 KB, schema 1, replacing the last report), and the flows
are validated against it again. The node panel turns a reported port's
config schema into a form, a reported screen is a canvas preset and a
touch screen's first report turns Touch friendly on. An offline device
node is degraded: amber on the canvas, a warning on Home, never a fault.
- NodeDef `device`/`device_policy` become `worker`/`worker_policy`, the
issue `ignored_device` becomes `ignored_worker`, and the SDK's `@node`
takes `worker=` and `worker_policy=`
- FlowStore._migrate renames the keys in published and draft documents
once, bumping their version; a queued run's `needs` reads the old key
- placement passes the label as `label`, client regenerated
- docs: worker placement wording, MCP issuer without DOMAIN, device rows in
the CLI data directory and the API table, device links in compose comments
- flow/nodes/device.py: `device` node with params `device` and `config`;
provides the device's `in` ports, requires its `out` ports without
waking anything, never run (Node.passive), down "Offline" from presence
- DeviceDef.io and DevicePort go; GET /devices/{id} computes `io` and
`bindings` from the device nodes of published flows, in a fixed order,
cached by FlowStore.revision; the credential's scope comes from them
- issues `unknown_device` and `device_port` (wired twice; against a report
the wrong direction or dtype, or unlisted as advisory), rechecked when a
device is created or deleted; ValidationIssue.advisory is a field
- a device publishing on a bound port is credited to its node by the
server; the panel endpoint kind is gone from `_endpoints` and the canvas
- a rebuild that moves a device's bindings sends `dashboard_changed` with
an empty name, which the firmware refetches on
- startup moves each device's `io` rows into device nodes in the flows
declaring their messages, draft and published, one commit; rows no
flow declares are logged and left out
- frontend: Device node settings (device, Publishes, Follows, a port
picker from a report), palette shortcuts per reported port, DeviceDetail
lists bindings with "Use in flow" in place of the I/O editor
- docs: devices, flow editor, node types, issues, API
- flow/devices.py: DeviceDef in FLOWS_DIR/_devices/<id>.json, committed under
the flow store's write lock, 409 on a stale version; nonces in DEVICES_FILE
outside git; in-memory presence announced as device_status
- api/routes/devices.py: CRUD, pairing with an optional {name, board,
firmware}, a pending list adopted without a code from the LAN only, unpair;
/panels/pair, /panels/pair/{code} and GET /panels/{id} kept as aliases,
PUT /panels/ gone
- _device_may replaces _panel_may, JWT claims unchanged
- panels.json moves into devices once at startup, then .migrated
- MCP list_devices, get_device; search category device
- Devices tab (list, detail with presence, pairing, ordered dashboards,
touch, I/O), PanelsDialog removed, serialised optimistic saves
The clipboard spec selected text in the previous node's panel while it was
still sliding out after the paste, so the selection collapsed when it
unmounted and the canvas took the copy. The values spec read the panel's box
mid-slide-in, where the translate leaves the width a float off 400.
The portal's copy of the dashboard is the `appshell` target of
backend/Dockerfile (18 MB instead of the 252 MB nginx image); the nginx
frontend Dockerfile, its confs and csp.check.ts are gone, since the app and
the hub both hash the CSP from the index.html they serve.
The runtime image copies the 4 MB git binary alone: the store's init, add,
commit, gc and rev-parse are builtins, and a build-time round trip fails the
build if that ever changes. About 100 MB of perl and helpers less.
The bundled Redis's overcommit warning and FastMCP's lifespan warning no
longer greet every `docker logs`.
The backend image now builds the SPA and serves it on the API's own origin
(fluksio/spa.py), so an instance is a single container with no proxy, DNS,
port 80 or .env: `docker compose up -d` with the new compose.yml runs it on
localhost:8080. It starts on fluksio serve (persisted secret key, first
admin printed once) and brings its own Redis when REDIS_HOST is unset.
Slimmer: python:3.13-slim, no dev group, uv once, fastapi without the cloud
CLI. Optional features are per-feature extras (mqtt, influx, email, sentry,
ml, server for all) picked with the EXTRAS build argument; numpy moved to
`ml`. ffmpeg left the image for imageio-ffmpeg via the Modules screen.
The operator stack runs the same image with app. and api. routed to it; the
nginx frontend service, the LAN nginx proxy and DOMAIN in the backend are
gone, and the MCP issuer is FRONTEND_HOST.
Copy widget in the widget panel or mod+c keeps one widget in localStorage;
a paste button in the dock and mod+v insert it below the other widgets with
a fresh id. Placement is shared with adding a widget.
frontend/scripts/no-em-dash.ts walks src/ with the TypeScript parser and flags
an em-dash in JSX text, string literals and template text. A bare "—"
placeholder passes, separators go in no-em-dash.allow.json. The script is
identical to index's copy.
