llama-server is started without -np, so it serves one request at a time and
everything else queues. Mail extraction is allowed two minutes on a Thinking
1.7B, and the reader hands core up to 25 messages back to back. A turn arriving
mid-extraction therefore waited for whatever was left of that budget: the router
timed out into the classifier cascade and its 36.8% floor, and the phraser, which
has no floor, simply waited. Memory evaluation had the same shape with a five
minute budget.
llm.Gate is the bound. Foreground requests never wait. Background requests run
one at a time and yield while a foreground request is in flight, plus a quiet
window after it that covers the gap between the router call and the phraser call
of one turn. Clients get their priority from llmClientFor or
llmBackgroundClientFor, so which side a caller is on is decided at wiring time.
It gates only what goes through those clients, which the comment on Gate says.
mail intake: the extraction timeout no longer wraps the capture writes. A model
answering at 119 seconds of a 120 second budget left the first CaptureTask one
second and the third none, so candidates the model had already produced were
dropped with a deadline error. The mailbox name is validated before it becomes
provenance, since "email:" is not a source and neither is an arbitrary string
posted at the socket. The enable log prints the normalised candidate bound
rather than the configured one, which said "max 0" and then wrote three.
Found in review of #64.

Things arrive at Maven from eight directions — a relayed Android
notification on POST /api/ambient, mail candidates from mavmaild, RSS
items, changed pages from the crawler, zenmoney and wg reads from
mavpoll, CalDAV events, presence probes, meeting transcripts and image
descriptions. Each grew its own shape and its own log line, and nothing
could answer "what came in today, from where".
internal/event is that answer: a flat source-agnostic envelope (Source,
Kind, EntityIDs, Title, Body, Priority, OccurredAt, Payload) plus a
bounded in-memory journal. Both are pure — Publish and Normalize take
`now` as a parameter, so no clock read sits on a path a replay would
drive.
Adopting it did not touch eight callers, because every intake path
already converges on three ipc.CoreAPI methods: WriteFact, WriteNote and
CaptureTask. cmd/mavend/intake.go decorates that ONE interface, so
mavweb, mavcaldav, mavpoll, mavmaild and the in-core feed/crawl/capture/
vision workers publish envelopes without knowing events exist. The lone
exception is cmd/mavend/mail.go, which captures through the store
directly and now publishes explicitly.
Nothing dispatches on an event. It is a report that something arrived,
never an instruction to speak — "a feed item appeared" becoming a
notification is the nag this repo refuses. Digestion may read the
journal later; it will still go through internal/loop's rules and the
severity/presence routing table.
Read surface: ipc.MethodRecentEvents (AuthRead, daemon-cached like
TickTrace — a bare store cannot serve a ring) and a read-only /events
page in mavweb.
Production is unchanged when nobody is watching: a nil *event.Bus makes
Publish a no-op and newIntakeAPI returns the wrapped API untouched, so
config.intake_journal < 0 leaves no decorator on the call path at all.
The default is 512 entries; the "off unless configured" rule is for
capabilities that reach out, and a bounded in-memory log of writes core
already performed reaches nowhere.
Verified: make build, make test (go test -race) both clean. New tests
cover the envelope and ring (internal/event, 95.7%), the decorator's
invariants — a failed write publishes nothing, a deduped capture
publishes nothing, OccurredAt is the fact's Ts and not notice time — and
the /events page including escaping of feed-supplied titles.
Loading a different gguf was a one-line edit to phraser.model_path plus a
restart. It is now an owner-triggered IPC call, off unless configured.
internal/phraser/swap.go holds the safety properties as code:
- Never two models resident. The old llama-server is killed and reaped
before the new one is launched. One 1.7B fits the Vega iGPU; a
blue/green overlap would OOM the box, so it is not offered.
- Atomic from a turn's point of view. Swap drains the in-flight turns
(they finish on the old model), then refuses arrivals with ErrSwapping
until the new server has answered /v1/models. No turn ever sees half a
swap; refused turns fall back to the classifier cascade.
- A failed load rolls back. If the new model does not start or does not
probe, the previous one is reloaded and the call returns RolledBack
with the error. If the rollback also fails the daemon says so and
degrades to the classifier rather than pretending to serve.
Holders of the completion client are re-pointed, not rebuilt: llm.Client
guards its base URL and LLMPhraser.OnSwap re-points it, so the router, the
replier, the mail extractor and the memory evaluator follow the new port
without knowing a swap happened.
Reach is deliberately narrow. phraser.swap_models is an exact-match
allowlist of absolute paths a human wrote, rejected at startup otherwise,
so "swap the model" can never mean "load any file on my disk"; the running
model is always swappable back to. MethodSwapModel is AuthStepUp, the same
rung as mutating the tool allowlist, and /models gates POST through the
same stepUpOK the tools page uses. Nothing calls Swap on a timer and no
act, intent or utterance reaches it.
Vikunja #250
The extraction half. internal/email.Extractor asks the resident Qwen3-1.7B,
under a GBNF grammar, what one message requires of him, and returns at most
three short candidates with an optional date.
Everything it can produce is a row in `tasks` with status "candidate",
written through the intake seam #130 built for exactly this (Source
"email:<mailbox>", Evidence = the subject line). No reminder, no fact, no
note, no calendar event. That bound is the design: a reminder FIRES, so a
1.7B misreading "встреча была в четверг" as a future appointment would wake
him up about it, whereas a wrong candidate is a line he dismisses in one
click. A due date the model read out of the mail is stored on the candidate,
where no scheduler reads it — the review page sorts by it. Relative wording
("до пятницы") is deliberately left in the text rather than resolved to a
date the model would get wrong.
The prompt is written against the two things a small model does here: it
summarises when asked to extract, and it invents an obligation out of a
polite closing line. Hence the demand for a verb phrase, and an explicit
empty array — most mail contains no task, and a model with no way to say
"nothing" says something.
Wiring: core owns extraction because llama-server lives in core's process,
so the reader hands messages over a new ipc.MethodIngestMail. It is a Server
hook (like StepUp/UnlockFn), not a CoreAPI method — not a store operation,
and no CoreAPI implementation should have to carry it. The hook stays nil
without an `email` config block or without a llama-server phraser, so the
method answers ErrUnknownMethod: off unless configured, twice over. There is
no keyword fallback on purpose — "the subject became a task" is a mailbox
rendered as a to-do list, not extraction.
Privacy: junk is refused before the model is called, mail text is never
search input, extraction errors carry byte counts rather than the reply, the
stored evidence is a truncated subject, and the log line names the mailbox
and the UID only.
