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.
The alert manager kept its cooldowns and its ceiling per hour in memory, so a
node that stayed down was announced again by every restart. Each delivered
alert is now a row in the new alert_sent table (additive migration), loaded
for the last seven days when the manager starts and pruned as new ones come
in. A ledger that fails never stops an alert. The manager's clock is wall
time for the same reason.
A node_health "down" alert also waits 60 s (HEALTH_GRACE_S) in a pending task
per node; a later event that is not "down" cancels it, as does stopping the
manager, so a broker restarting with the stack alerts nobody.
The cooldown used to be stamped before the ceiling per hour was checked, so
an alert the ceiling held back still spent its cooldown. It is stamped only
once the alert is sent now.
The summary read degraded for 15 minutes after any single node_error, even
once the node had run well again and including one bad input from a visitor.
The controller now counts a node's failures since it last ran well and notes
when it recovered; both carry across rebuilds and an acknowledgement resets
the count. Two in a row inside the 15 minute window is "failing" (a problem),
one is listed under warnings, and nodes.failing keeps meaning "failing now".
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>...
_serve_once treated a cancelled call future as finished, so an event loop
cancelling all tasks at once (shutdown) never sent the worker a cancel and the
call's thread kept asyncio.run waiting for SILENCE_S. The cameras audio test
now removes its voice flow and device, the unpaired-frame test waits for its
first frame before the unpair, and test_connector no longer inherits the
controller an app test bound to demand.
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.
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.
Every output is a target and every input besides prompt a reading. A
targets setting gives descriptions, values, ranges and per-target
guards, model takes a trained pack's artifact digest, min_confidence
defaults to the model's threshold. A command is applied whole or not at
all, and targets the model was not trained on read degraded. The home
path (area/kind ports, groups, brightness, temperature answers) is gone.
wren's model answers "turn off all lights" with one call, and at 0.98 a
living room light switched on. The node now applies such a command to every
wired target of the kind. Number words become digits ("in five minutes"
lost its delay), aliases put the house's words and known mishearings in the
model's, and sensors.temperature is answered from <area>_temperature or
outdoor. tts writes out units and clock times before speaking.
wren drops a call on an area the command does not name (other than the
user's or, with none named, the living room): "switch on the appliances"
turned on the bathroom light at 0.97. The assistant's `values` setting gives
a str target its only values, explains them in the tool and confirms in the
word set for each ("Canopy open.").
Shown only the wired areas, the model took "turn on the bathroom light"
for the living room's light and "the office light" for the kitchen's,
both above 0.93: 5 of the 28 recorded 7B commands switched a wrong light.
Every area is shown now, with a light each, so such a call names an
unwired device and goes on to `unhandled`.
With every area shown, a transcript's "Turn on the kitchen light." fell
to 0.80. The command is passed lower case without sentence marks, as the
model was trained, which brings it to 0.99.
run_turn takes answer_tools: false ends the turn once the tools have
answered. The assistant node uses it and says what was set ("Kitchen light
off, living room light off."), which saves one model round, about 1.1 s on
the P100. A turn without a call still streams the model's own words.
rebuild-frontend keeps the running stack's FRONTEND_HOST, so the token
issuer no longer flips between the LAN address and app.localhost.
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.
transcribe and speak share an httpx client per speech server with a 300 s
keep-alive, and run on the engine's loop. stt warms it with GET /v1/models
when an utterance opens, so a reply's first sentence finds the connection
open: a new one over a lossy link cost up to a second (openpanel V4).
