PhraseChat and PhraseQuery returned canned text with a nil error, so a dead
or OOM-killed server was indistinguishable from bad phrasing — "не знаю." is
also a legitimate answer.
Both now return the fallback text AND the error. The daemon keeps using the
text, so the turn still survives; a measuring caller counts a real failure.
An empty response is its own error: the model is up and said nothing.

Nine reply cases and a fourth column in the talk report. The reply path is a
separate object from the phraser in the daemon, so Pair joins a Talker and a
Confirmer for a run that covers everything Maven says.
Cases carry intent/key/value because the replier is phrased from the decision the
router resolved, not from the raw utterance. Three of them are baits the other
paths cannot produce: a masculine verb about himself that she must not copy onto
herself, a polite plural input that must still come back на ты, and an unresolved
note that invites a question a confirmation is not allowed to ask.
Not scored against a model here — this box has no llama-server, and the baseline
test is opt-in on MAVEN_LLM_URL.
llmReplier lived in cmd/mavend, so the confirmation he hears after every fact,
note and reminder was the one phrasing path nothing could import or score.
Replier owns the prompt, the call and the parsing, and returns its errors instead
of hiding them — a dead model shows up as an error rather than as bad phrasing.
It has no stub fallback of its own; the daemon keeps that. StripThink is exported
for the daemon's own model callers.
#496 asked to skip the veto when the question and the hit are in
different scripts, so an English question stops losing a Russian note.
Measured first: the fixture has no cross-language case, and en-hard-024
is an English question against an English note. Both proposed fixes are
no-ops.
What the veto actually does on the fixture, with the real embedder: it
costs en-hard-024 and buys ru-silent-029. Pass count is 22/32 either
way; false recall is 0/5 with it and 1/5 without. The two cases are one
lexical class, so no rule cheap enough for RecallAllowed separates them.
Accepts the loss and pins both sides in a test.

The forwarded log named the cause in one line: the prompt cache limit
defaults to 8192 MiB. llama-server saves the full KV state of every idle
slot it evicts, 112 kiB per token, so RSS climbed about 170MB per
distinct prompt until the deployed server held 7.9GB for a 1.1GB model.
Measured on homesrv today, uncapped versus `--cache-ram 512`: RSS
plateaus at 932MB from the fourth distinct prompt instead of climbing.
The task's leading guess was wrong. `-ngl 99` costs almost no RSS,
because RADV keeps device memory outside the process. Numbers and method
in docs/evals/2026-08-03-llama-prompt-cache.md.
`-c 4096` is untouched. The knob is `phraser.cache_ram_mib`, unset means
512, negative passes no flag for a llama-server too old to know it.
The deploy still runs the old image, so the box keeps its 8 GiB default
until mavend is rebuilt.

mavend scraped the child's stderr for the listen line and threw every
other line away, and never piped its stdout at all. Nothing about the
resident model's memory was diagnosable from a running box: no buffer
sizes, no KV-cache layout, no offload lines, no prompt-cache limit.
Both streams now share one pipe and every line lands in mavend's log
with a `llama:` prefix. The last 12 startup lines are also kept and go
into the error when the server dies before it listens, because bare
"EOF" never named which allocation it choked on.

Automatic rather than a flag, unlike -reembed: only voice-tapped facts are in
this index, so it is tens of embeddings rather than thousands of notes. And
waiting for an operator to know the repair exists is the failure being fixed.

Every write-path fix leaves the rows already stored wrong, and a box in that
state looks fine: recall answers with the wrong text and nothing logs an error.
That is how the original poison survived four restarts.
RepairFactVectors resolves each fact vector against the fact it names,
re-embeds the ones whose text is stale, and deletes the voided, superseded and
orphaned ones. Marker-guarded and idempotent, so it runs once per box and a run
that dies partway is simply redone.

queryMemory returns a fact's stored text verbatim, so the text the write path
indexed is what he hears. It was the utterance, which made recall of any
voice-tapped fact answer with the sentence he said: go_version = 1.20 was
indexed as "какая последняя версия языка Go?", and that question came back.
FactRecallText renders the fact instead, and the utterance stays in meta as
provenance. Correcting a value now drops the key's vectors the way voiding one
does, since the superseded value was still answering.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
queryMemory and queryNotes both gate on score alone, so both needed it. The
eval keeps its own copy of bestRecall — package main is not importable — and a
fixture that measures a weaker gate than the daemon runs flatters it, so the copy
moves in step and its test pins the new rule.
Measured on the held-out recall fixture with the real embedder: 17/32 cases pass
→ 22/32, false recall 1/5 → 0/5, answered after gate 18/27 → 17/27. The one true
recall lost is en-hard-024, an English question against a Russian note, where no
lexical test can help.
The score gate cannot separate the right note from an unrelated one: the
held-out fixture puts the right note at 0.791-0.890 and the must-be-silent cases
at 0.795-0.835, so a note about his slow network answered 'почему небо синее?'.
RecallAllowed adds a topic veto, and applies it only to a question that mentions
nothing of his. That restriction is the whole design: demanding a shared word of
every recall silenced four true recalls on the fixture to kill one false one,
because recall exists to find the note whose words he no longer remembers. A
question about his own life keeps the embedder as its only judge.
The predicate a fact write needs before it trusts a routing decision. Tokenized,
not substring: 'что' inside 'чтобы' is not a question. Capture verbs win over
every question signal, because 'запиши что я пил воду' contains an interrogative
and is still a capture.
Revert voided the fact row and left the vector, so recall kept serving the
voided fact's utterance and the documented repair reported success on a box that
stayed broken. There was no way to repair a poisoned box at all.
DeletePrefix covers every vector for the key, earlier rows included: their values
are superseded, and a superseded value has no business claiming a turn. It is
best-effort — the audit trail is already committed, and a fact that is voided but
still recallable beats a void that failed.
Owner's correction. It is the same host CLAUDE.md already calls workpc, and
two names for one machine read as two machines. The dated eval file keeps the
old name: a measurement is never edited after the day it was taken.
The middle outcome is the whole task: a workstation that is configured and
asleep produces a gap, and the resident model is never asked. The parity
test compares the bytes PhraseWorld sends the workstation against the bytes
PhraseQuery sends the resident model, so the fixtures and the daemon cannot
measure two different prompts.
The nudge tests cover the silent half from both sides, including the
temperature, which is how the workstation would otherwise change how she
sounds without anyone deciding to.
The naming half of the degradation rule in docs/offload.md. PhraseWorld has
three outcomes: no workstation configured means the resident model answers
exactly as today, a workstation that is taking work answers, and one that is
asleep returns ErrNoWorldModel so the caller can say so. Naming a gap
requires a gap — on a box that never had a second model, refusing every
world question would remove a capability he has now.
Both prompts move into knowledgePrompt and evidencePrompt, shared by
PhraseQuery and PhraseWorld, because prompt parity across two models stops
holding the moment there are two copies of a prompt.
The silent half comes with it: chatWithSystem and chatWithMessages prefer
the workstation when it will take work, at the same 0.7 the resident
transport samples at, and say nothing when it will not. That covers the
digestion worker's nudge and reminder phrasing without touching tick.go.
Only Available and CompleteRemote are in the Remote interface. Pair.Complete
has its own floor and the phraser already owns one; two floors under a
single call is one too many.
The phraser's own transport has always sampled at 0.7 and this client has
always been greedy. Routing a phrasing call through the client must not
change how it decodes, so Req carries the temperature and 0 — the zero
value, and what every existing caller wanted — is still greedy.
Seven cases. The load-bearing ones are the constraint from 483: an
unconfigured deploy never probes and always reaches the floor, a busy
card degrades silently with the remote untouched, and a remote that dies
between probes still completes the turn and corrects the cached answer on
its way out.
CompleteRemote is pinned not to fall back, because a named gap that
quietly became a 1.7B guess is the failure this whole split exists to
prevent. And 1000 Available calls are pinned to make zero probes.
Pair holds both models and decides which answers. A prober asks the
remote whether it will take work and caches the answer, so a request
reads an atomic bool rather than paying for a health check. Routing sits
at p50 825ms on the hot path and must never wait on a machine that may be
asleep.
The two methods are the two halves of the degradation rule in
docs/offload.md. Complete falls back silently, for routing, replies and
nudge phrasing, where the big model is only better. CompleteRemote
returns ErrRemoteUnavailable instead, for a world question, where the
1.7B does not answer worse but invents.
A nil remote is the unconfigured deploy: nothing probes, everything goes
to the floor, and the box behaves exactly as it does today.
Five hardcoded transports, three in internal/ipc and two in
internal/worker, all now go through the seam address. The unix perms
logic moved into netaddr, so the two copies of parentDir and the umask
dance are gone.
peerCaller already returned ok=false for a non-unix conn, so the
SO_PEERCRED path degrades correctly on tcp with no change.
Six cases. The load-bearing one is the first: every deploy in the tree
writes a bare path, and it must keep meaning a unix socket with no
handshake in front of the payload.
The rest cover the tcp seam: a good token round-trips, a wrong one comes
back ErrUnauthorized, a stranger that speaks HTTP at the port is dropped
while the listener stays up for the next peer, and a tokenless tcp bind
fails rather than serving his turns to anyone who connects.
internal/netaddr parses a daemon seam address and dials or binds it. A
scheme-less address is unix and behaves exactly as it does today: same
0700 parent dir, same 0600 socket, same bytes on the wire. tcp://host:port
is the new option, and it is what lets a module live on another host.
Over tcp the filesystem permission that authenticated the unix socket is
gone, and what crosses this seam is audio of the owner speaking. So a tcp
listener requires a shared token, checked in constant time before the
first protocol frame is read, and a peer that fails is dropped without
taking the listener down with it.
Every phraser test built the phraser with NewLLMPhraserAt, which starts no
process, so NewLLMPhraser, spawnLlamaServer, startLlamaProc, llamaProc.Close
and extractPort sat at 0% while the package headline read 65.3%.
These drive the real spawn code against a fake llama-server script: the port
scrape, the three reachable startup-race arms (start failure, stderr EOF,
context cancel), and Close actually reaping the child. The orphan test
re-execs the test binary as the daemon, SIGKILLs it, and asserts Pdeathsig
killed the grandchild. The last test rebuilds the production command line and
checks kill-maven.sh's pattern still matches it — that pattern has gone stale
twice and leaked orphans both times.
Package coverage 65.3% -> 76.9%. The 60s timeout arm stays untested; it needs
an injectable clock in production code.

#400 rewrote the chat and query prompts in Russian and left three pieces
of English prose behind.
PhraseReminder's user prompt was fully English. It is Russian now, and it
no longer restates the JSON contract or the persona rules: the call goes
through chat(), so nudgeSystem already states both, and a second copy of a
contract is one more thing that can drift out of step with the first.
querySystemPrompt and router.KnowledgePrompt both closed with the English
"Respond ONLY with valid JSON:". That sentence is prose instruction, not
wire format — the JSON skeleton after it is the wire format, and it is
unchanged. Kept rather than deleted: the GBNF grammar makes it close to
redundant, but the grammar is switchable off (phraser NoGrammar), and the
sentence is the floor when it is.

Seventeen markdown files at the repo root, twelve of them dated one-shot
reports sitting next to CLAUDE.md. That is why stale docs read as
current: nothing in the path said which was which.
Root now keeps CLAUDE.md and AGENTS.md. Living docs move under docs/
and carry a Last verified line. Dated measurements move to docs/evals/
ISO-prefixed, and are never edited after the day, so a newer number is
a new file. The senior review moves to docs/archive/.
Every reference was rewritten across markdown, Go comments, the Makefile
and the recall fixture. The touched Go packages still build.

The evidence branch of PhraseQuery framed every source as "твои заметки" and
joined them into one quoted run-on. A live search snippet is not his note, and
a run-on gives a 1.7B one blurred claim to merge rather than sources to answer
from. That is the shape that named Левитан as the author of Война и мир.
Sources now arrive numbered, one per line, and the system prompt says three
ways that the answer comes out of them: only from the sources, say plainly
when they do not answer, add nothing of your own.
Blank sources take the knowledge branch. One empty string used to reach the
evidence branch and ask the model to answer from an empty list, which is the
one prompt guaranteed to make it fill the gap from memory.

The replier and the meeting summariser were the two call sites without a
GBNF. Both are exactly the shape that makes a Thinking variant answer with
its reasoning as prose, and neither had anything downstream that could
remove it.
The replier already parses {"response","mood"}, so it now sends the phraser's
grammar for that contract, exported once as phraser.ResponseGrammar so the
two definitions cannot drift.
The summariser stays text-in/text-out. The JSON wrapper is attached and
unwrapped in the daemon's Completer, so internal/capture is unchanged and a
Completer without a grammar still works.
The simulator told routing from phrasing by "has a grammar", which stopped
being true here; it now looks for the intent enum.

The offline encyclopedia was the only world source, and it reads what was true
when the ZIM was built. A self-hosted SearXNG now asks first and Kiwix is the
fallback for an empty result, an unreachable instance or no line out. Owner's
ruling, 2026-08-02.
internal/websearch is deliberately thin: no rewriter (SearXNG ranks through
real engines, so the Russian question goes out as he asked it), no page fetch,
no cache. It cannot read the store, so only the query string can leave the box.
The personal boundary is unchanged and still sits above this source, so a
question about him is never searched.

wireVoice runs before the tick loop exists, so it could only be handed
the bare store adapter — and that adapter answers DayPlan with "not
available via direct store API", because a day plan is assembled by the
tick loop and is not a table to read. So queryDayPlan, which the query
chain reaches for "какие у меня планы на сегодня", failed for every
caller on the deployed daemon.
main already back-patches the other direction (daemonAPI.chatFn =
handler.handleText). This is the same seam in reverse, at both wiring
sites. No recursion risk: nothing in the voice path calls api.Chat.
With the plan reachable, it recited its reminders as literal JSON. The
payload unwrapper existed but was private to the phraser, so the day
plan had its own non-unwrapping copy. One owner now, store.ReminderText,
with the phraser delegating to it.

"что у меня сегодня" and "что у меня в календаре сегодня" both routed
IntentSystem on the deployed daemon, and replySystem has no agenda arm,
so both answered "пока не умею". The calendar source that can answer
them lives in the query chain and was never reached. The fixture has
said query since ru-query-019 was written; the daemon disagreed with the
fixture and the daemon was wrong.
AgendaQueryGrammars routes them at stage 0, after the clock rules so
"какой сегодня день" keeps reaching replySystem. Intent only — which
source claims the turn stays the query chain's decision.
This is what made the follow-up continuation look like it only worked
for "what day is it". It did: the query half inherited an intent whose
handler could not answer, so both halves came back "пока не умею".
Measured on the 77-case RU fixture: full accuracy 70.1% → 72.7%,
intent-only 75.3% → 77.9%, calendar 0/2 → 2/2, clarify counts unchanged.
The eval harness wires the new grammars too, or the fixture would stop
being a measurement of the daemon.
Go's \b is ASCII-only and never fires after a Cyrillic letter, which the
first version of the pattern learned the hard way.

Deployed check, second round: "привет" after "какой сегодня день" answered
with the date. followUpMerge fills an empty Text from the previous
same-intent turn, so the topic-widening added a minute earlier was reading
an inherited topic on turns that had nothing to do with it.
Decision gains Continued, set only by continuation.go and never by the
router. replySystem widens on that and nothing else, so an inherited Text
is back to being invisible.

The clarify gate thinned any one-word utterance to 0.3 confidence, which
trips the stage-3 gate and comes back as "не совсем поняла". That is an
English intuition. Russian packs subject, tense and gender into one word,
so "поужинал" is a complete report and "привет" a complete greeting, and
both got clarified.
thinSingleToken keeps the rule for bare nominals, where it is real ("вода"
is a fact-or-query coin flip), and spares two classes: a closed lexicon of
social and control singles, and any token carrying a verb ending. Both
tests are offline.
Fixture: false clarifies 3 → 2, intent-only 74.0% → 75.3%, full accuracy

The kuma service_down nudge cannot name the service. mavpoll folds the whole
monitor_status gauge into one boolean fact keyed `service_down`, and the
phraser names a service only when the fact key is the service name, so the
message is always the generic "a service on homesrv is down". Every fifteen
minutes, with nothing to act on. A fact per monitor is the real fix and it is
filed as Vikunja #444; this is what to do until then.
`disabled_rules` in mavend.json subtracts from loop.DefaultRules by name.
Config only subtracts — rules stay code, the set stays canonical and ordered
as written. A disabled rule is not gathered for either, since the gatherer
derives its key set from the rules it was given. Unknown names are ignored so
deleting a rule cannot brick a config that still lists it, and the boot log
says what was dropped, because a rule that vanishes silently looks exactly
like a rule that is broken.
Deploy turns service_down off.

mavend seals its encrypted database in `defer st.Close()` when run() returns.
It had not returned since 2026-07-21. Every restart since then decrypted the
same eleven-day-old ciphertext and rolled back everything written in between:
the Telegram nudge that kept firing was a fact being un-written on each boot.
The goroutine dump named it. main → srv.Close() → ipc.(*Server).Close →
wg.Wait(), waiting on per-connection goroutines parked in readFrame. Close
shut the listener and nothing else, so the idle persistent sockets held by
mavweb, mavpoll, mavcaldav and mavmaild blocked shutdown forever. `docker
compose stop -t 60` spent the whole sixty seconds and then took a SIGKILL.
So: track the accepted conns and close them, in ipc and in voice, which had
the identical defect. Bound all three waits — the two per-server ones and the
worker wait in main — because the seal matters more than any single in-flight
call. A dropped RPC costs one reply; a missed seal costs a session.
The regression test leaves a client connected and idle, which is the case the
old tests avoided by closing the client first.

Two things that were each half-done.
The prompts handed the model copyable examples. chatSystemPrompt lost its
openers this morning and the "Я подумала, что" tic went with them, but "не
забыл ли я" appeared in its place: the removed example had been suppressing
the masculine self-reference by accident. Two predicatives are not enough
signal, so the rule is now stated as morphology (-ла) rather than as a pair of
words — a suffix rule generalises where an example only gets copied.
querySystemPrompt had the same defect and gets the same treatment; its "вот что
я нашла: " opener is deliberate and stays.
internal/kiwix had no caller. actions_query.go said "once internal/kiwix is
wired into this chain" and that never happened. It is wired now, between the
notes pass and the web source: everything of his answers first, and only what
is left over is looked up. Off unless a `kiwix` block names a server and a book.
Reading the search snippet does not work. Kiwix builds it from wherever the
keyword matched, which on Wikipedia is the navigation box at the foot of the
page — the first version of this answered "что такое фотосинтез?" by reciting
"Ecological economics Ecological footprint Ecological forecasting …". Client
grows an Article method; the head of the article is the lead paragraph, which
is the definition the snippet was meant to be. Verified on the box: the same
question now answers correctly off the ZIM.
Only the rewritten query leaves the process. A test asserts it: a turn carrying
a stored note must not put that note in the search string.

The grammar examples in chatSystemPrompt were full clauses — ("я подумала",
"я рада") for her, ("ты сказал", "ты забыл") for him. A 1.7B copies those
instead of generalising from them.
Observed on homesrv 2026-08-01, in one session: all three chat replies
opened with "Я подумала, что ...", and one ended "...немного тревожусь.
ты сказал" — the second example pasted onto a finished sentence, which
reads as a truncation and is not one.
Contrastive pairs replace the openers, so the rule reads as a correction
rather than a template. The him-examples are dropped; the "ты" instruction
carries that on its own, and those two produced the worst output. A closing
line tells her not to echo the instructions, because a small model treats a
quoted string as licence to reuse it.
Verified after rebuild: three chat turns, no "Я подумала" opener, no
dangling example, feminine forms intact.

net/http wraps every transport failure in *url.Error, whose Error() prints
the request URL. Telegram accepts the bot token nowhere but the URL path, so
a send failure wrote the live token into the daemon log. On 2026-08-01
homesrv could not reach api.telegram.org and did that once a minute for as
long as the network stayed down. The token lives in deploy/telegram.env to
stay out of the repo; putting it in `docker compose logs` undoes that.
Both error sites now go through redact. The structural branch rewrites
url.Error.URL and keeps the type, so errors.As still matches; anything else
falls back to scrubbing the rendered message. No minimum-token-length guard:
a one-character token would shred the message, but that beats leaking it.
DESIGN.md still said the classifier cascade was the path that runs today
with llmrouter wired nil, and gave the resident checkpoint as Qwen3.5-0.8B.

IngestMail was AuthRead and SetTaskStatus was AuthWrite, and they answer
the same question: may this module change what is on his lists? The old
argument for AuthRead — ingestion is additive, it can only produce
candidate tasks — is still true and is the weaker half, because a
compromised mail reader that can fill the review page indefinitely is
not a read.

Two fix branches independently added a Gate to internal/llm. One is priority
between a voice turn and a background job, the other is admission control while
the resident model is swapped. They are orthogonal and both are needed, so the
swap one is now SwapGate, with SetSwapGate to install it.
Complete takes the priority gate first and the drain second. A background
request can wait a long time on priority, and counting it as in flight against
the drain that whole time would stall a swap on a request that has not started.

capture_stop held the IPC request open for the whole map reduce, up to
twenty minutes. A voice turn that says "хватит" waited for forty model
calls before Maven said anything. Stop now returns the transcript and the
summary runs on a goroutine in the daemon's WaitGroup, on the daemon
context so a client that hung up does not cancel the only readable record
of the meeting.
With no summary and save_transcript false, writeNotes wrote nothing at
all: an hour of meeting left a blob that prunes in seven days and no
trace in the note store. The transcript is written instead when the
summary is missing. That flag decides whether the verbatim record is kept
in addition to a summary, not whether the meeting is remembered.
The wire carries the session token now, and the contract comments say
what the code does: the summary is usually absent from the stop
response, and re running a stored blob is a manual job because no method
takes a blob id. The save_transcript comment says the cost is recall
corpus rather than disk.
Found in review of #73.
Four invariants the comments claimed and the code did not hold.
The recording lived in mavend's heap as one growing []byte, doubled at
Stop when the WAV was built. Frames now go to a spool file and the
transcript is read back off disk one window at a time, so memory is flat
whatever the length.
A store failure returned before transcription ran, so a meeting over the
blob cap produced no transcript, no summary and no note. It now records
the failure and keeps going, and the spool file survives until the words
have been read off it.
The session had no owner. Any module on the write rung could call stop on
a recording it did not start and receive the verbatim words of everyone
in the room. Start hands back a token and append, stop and abort require
it.
The duration cap was only checked when a frame arrived, so a phone whose
tab was closed left the slot occupied and every later start answered
ErrBusy with a meeting from last week. The wall clock is checked in
start, status, append and stop.
Smaller things in the same pass. Append compares the frame format against
the session format, so a client that switches sample rate mid meeting no
longer has its frames concatenated under a header that lies. One failed
STT window leaves a marker instead of discarding the other twenty four.
Summarize is separate from Stop and assigns the salvaged per chunk text
before it reports the error.

Put takes a []byte, so storing a recording meant the whole recording in
memory. A two hour meeting at 16 kHz mono is about 230 MB of WAV, and
building it from PCM held a second copy of the same size in the process
that also owns the database and the resident model. PutFile stats the
file, hashes it in a stream and renames it into place, so the peak is one
buffer regardless of length. SpoolFile hands out the scratch file it
moves from, under the media dir so it shares the same disk and the same
permissions.
Audio also gets its own per blob cap of 512 MiB. The image cap of 64 MiB
is 35 minutes of audio, which contradicted the two hour session cap: the
long meeting was exactly the one that failed to store.
audio.WAVHeader is split out of WAVFromPCM because a spooled capture
writes a placeholder header first and stamps the real length at the end.
