router: stage 0 claims the task marker before the model renames it (V-467)

Spoken capture was dead. "добавь в задачи купить молоко" routed act, so the
gate found no allowlisted fn and asked "Что сделать?", and the list stayed
empty. Capture rides the note intent by design (#130, no eighth intent), and
nothing under actionNote was reached any more. The model also rewrote the
payload on the way — "купить молоко" came back as "сделать покупку молока",
and a task must read as the words he said.

TaskCaptureGrammar answers it at stage 0, the same place the agenda rules
went. It matches any utterance and lets ParseTaskCapture refuse, so the
marker list stays data. Three phrasings he used are added to that list:
"запиши в список дел" and the two next to it were missing.

The other deterministic matchers were checked for the same exposure. They
are all question-shaped — money, habit, feed, day plan, task list, calendar —
and a question lands on query, which is where they already sit. Capture was
the only imperative among them, which is why only it was taken.

ru-note-006 is the fixture case. The classifier alone cannot pass it, and the
hash baseline drops by that one case; the daemon answers it at stage 0.

+description: Start a work session on a Maven task. Runs task start, reads the brief and the disposable handoff, restates the assumption set, and waits for correction before touching code. Use at the start of any session that continues earlier work, when the user says "pickup", "continue", "resume", or names a Vikunja task id.
+---
+
+# Pickup
+
+The point of this skill is the pause in step 5. Every wasted session in this repo
+started with an agent that inferred the goal instead of stating it back.
+
+## 0. Get on the branch
+
+```sh
+task start <vikunja-id>
+```
+
+`~/.local/bin/task` owns the branch, the identity and the PR. It cuts
+`task/<id>-<slug>` off `origin/master` and sets the commit author to the `claude`
+gitea user. It writes `TASK.md` from the Vikunja task, and pulls any waiting
+review comments into `.task/review-comments.md`. Do not hand-roll any of that.
+
+`TASK.md` is the brief and it is immutable. If it says a PR already exists, this
+is a review-fix session and not new work. Read the comments first.
+
+## 1. Read the handoff
+
+`HANDOFF.md` at the repo root, if it exists. It is gitignored, it belongs to one
+session, and it holds only what is needed to resume. Treat it as a claim from the
+previous agent, not as truth. It can be stale or wrong.
+
+If there is no handoff, that is normal. It means the last session closed clean.
+
+## 2. Read the durable state
+
+In this order, and stop as soon as you have enough:
+
+- The Vikunja task, by id. Project Maven is ID 2, MCP at `http://localhost:9100/mcp`.
+  The task description and its comments hold the goal, the constraints, and the
+  assumption ledger. This outranks the handoff on every conflict.
+- `CLAUDE.md`, the section that covers the area you are about to touch.
+- The one file under `docs/` that owns the area. Check its `Last verified` line.
+  If the sha is behind the code you are reading, say so in step 4 and trust the code.
+
+Do not read the dated files under `docs/evals/`. They are measurements from one day,
+never updated. Read one only when you need the number it recorded.
+
+If no task id is known, ask for one before doing anything else. Work without a task
+is work nobody can resume.
+
+## 3. Look at the ground
+
+`git status`, `git log --oneline -5`, and the diff on the current branch. What the
+repo says beats what any document says.
+
+## 4. Restate, then stop
+
+Write at most five bullets and stop. Do not write code, do not open files to "check
+one thing first", do not start with a small safe change.
+
+```
+Task:        V-359, one line.
+Done:        what is already on the branch.
+Next:        the one thing this session does.
+Constraints: what would make this wrong.
+Assuming:    the beliefs that, if false, waste the session.
+```
+
+Then ask: is this right? Wait for the answer.
+
+A corrected assumption goes into the Vikunja task as a comment, not into the handoff.
+The handoff dies tonight. The task does not.
+
+## 5. Then begin
+
+- Delete `HANDOFF.md`. It has been consumed and must not outlive this step.
+- On master, cut the branch: `scripts/task-branch.sh <id> <slug>`.
+- One task per session. When context passes roughly half, run `/wrap` rather than
+  pushing on. A compacted session is a session that forgot why it made a choice.

+name: wrap
+description: Close a Maven work session cleanly. Runs the tests, updates the durable docs, commits in reviewable slices with the Vikunja ref, pushes so the PR opens, records state in Vikunja, and leaves a disposable handoff only if work remains. Use when the user says "wrap", "wrap up", "done for now", or when context passes roughly half.
+---
+
+# Wrap
+
+Run every step. A partial wrap is worse than none, because the next session trusts
+the parts that did run.
+
+## 1. Prove it works
+
+`make test`. If something fails, fix it or say plainly in the handoff and in Vikunja
+that it fails, with the output. Never wrap on an untested claim.
+
+## 2. Update the durable docs
+
+Ask what a future agent would have to learn the hard way, and write that down.
+
+- `CLAUDE.md` when a fact an agent needs before touching code has changed: routing
+  behaviour, a measured number, a flag default, a constraint. A commit that changed
+  routing or phrasing without touching the matching CLAUDE.md section is a bug.
+  Correct stale text in place. Do not append a new paragraph next to the wrong one.
+- `AGENTS.md` when the recipe to build, run or preview changed.
+- The one file under `docs/` that owns the area, plus its `Last verified: <date> @ <sha>`
+  line. Only a doc directly under `docs/` carries that line.
+- A new dated file under `docs/evals/` when you measured something. Never edit an
+  existing dated file. A newer measurement is a new file, and the living doc points
+  at it.
+
+Nothing that must survive tonight goes anywhere else. Not into the handoff, not into
+a commit message, not into a comment in the code.
+
+## 3. Commit in slices
+
+Under 300 changed lines per commit in non-markdown files, enforced by `.githooks/pre-commit`.
+Markdown is exempt and may land as one batch.
+
+Each commit is one idea, subject in the repo's voice, lowercase area prefix, and it
+ends with the Vikunja ref:
+
+```
+router: narrow the single-token rule (V-359)
+```
+
+If a change genuinely cannot split under 300 lines, say why in the commit body before
+reaching for `--no-verify`.
+
+## 4. Land it
+
+```sh
+task pr
+```
+
+It refuses a dirty tree, pushes, opens or refreshes the PR against the repo default
+branch, labels the Vikunja task in-review, comments the PR url on it, and pushes an
+ntfy. Do not push by hand and do not call `tea` yourself.
+
+## 5. Record what `task pr` cannot know
+
+Comment on the Vikunja task: what you measured, what is still open. List every
+assumption that turned out to be wrong. If the session found new work, create a task
+for it now rather than describing it in prose.
+
+This step is what makes the handoff disposable.
+
+## 6. Leave the handoff, or leave none
+
+If the task is finished, delete `HANDOFF.md` and stop. An empty root is the correct
+end state.
+
+If work remains, write `HANDOFF.md` with nothing but what the next agent needs to
+resume, and no history:
+
+```markdown
+# Handoff — <date>
+
+Task: V-359 <one line>
+Branch: task/359-<slug>, cut from master
+
+## Where I stopped
+<two sentences, mid-thought detail that is nowhere else>
+
+## Next action
+<the single concrete next step>
+
+## Do not
+<the trap I nearly fell into, or the approach already ruled out>
+```
+
+Nothing else goes in it. No summary of what landed, that is in git and Vikunja. No
+design rationale, that is in `docs/`. No fact an agent needs on any task, that is in
+`CLAUDE.md`. If a line in the handoff would still matter next week, it is in the wrong
+file.

+number is a new file. Files under `docs/archive/` are dead and read by nobody by default.
+
+## Git guards
+
+Two hooks in `.githooks/`, tracked, wired with `core.hooksPath`. Fresh clone:
+
+```sh
+git config core.hooksPath .githooks
+```
+
+- `pre-commit` refuses master, and refuses more than 300 changed lines in non-markdown
+  files. Markdown is exempt and may land as one batch.
+- `commit-msg` requires the subject to end with `(V-<id>)`. `V-` and not `#`, because
+  Gitea autolinks `#123` to a Gitea issue, which is the wrong tracker.
+
+Two more guards live outside the repo, in `~/.claude/hooks/`. `diff-budget.sh` blocks
+further edits past 600 changed lines on a `task/` branch. `prose_lint_hook.py` checks
+prose on every write. Both measure against `origin/master`, so a local master that is
+ahead of the remote makes the diff budget read high.
+
+`--no-verify` exists. Using it means saying why in the commit body.

+// about him, questions about the world — are embedded once, and the turn's own

+# gemma-4-12b on the workstation, against the resident Qwen3-1.7B
+
+Measured 2026-08-02 on the fixtures as they stand. Dated file: it is not edited
+after today, and a newer number is a new file.
+
+Vikunja #485's first assumption was that a 7-14B measurably beats Qwen3-1.7B on
+the 77-case RU routing fixture and the 27-case talk fixture. It does, on both,
+and it is also faster.
+
+## The setup
+
+`gemma-4-12B-it-qat-UD-Q4_K_XL` with the `mtp-gemma-4-12B-it-BF16` draft model,
+served by `llama-server` b10220 on bugmachine (AMD 7900 GRE, 16GB), fronted by
+`mavgpud` on `192.168.1.105:8080`. Thinking is off through
+`--chat-template-kwargs '{"enable_thinking":false}'`, speculative decoding is
+`--spec-type draft-mtp --spec-draft-n-max 2`, context 32768. The exact line is
+`deploy/mavgpud.json`.
+
+Every number below crossed the LAN from homesrv. Note the trap: homesrv's shell
+exports `HTTP_PROXY`, Go honours it, and the runs need
+`env -u HTTP_PROXY -u HTTPS_PROXY -u http_proxy -u https_proxy`.
+
+## Routing, 77-case RU fixture
+
+| | full | intent-only | p50 | p95 |
+|---|---|---|---|---|
+| classifier alone (02-08) | 68.8% | — | 16.6µs | — |
+| Qwen3-1.7B through the cascade (31-07, 02-08) | 72.7% | 77.9% | 0.80-1.04s | — |
+| **gemma-4-12b through the cascade** | **84.4%** | **93.5%** | **329ms** | 429ms |
+| gemma-4-12b alone, no cascade | 55.8% | 85.7% | 335ms | 436ms |
+
+The workstation buys 11.7 points of full accuracy over the resident model. It
+buys 15.6 points of intent-only, at a third of the latency. The router's p50 was
+never the model's fault, which the 02-08 contention finding already said. A 12B
+on a free 16GB card answers a routing turn in a third of a second.
+
+Two things the table hides.
+
+The alone-versus-cascade gap is slots, not intents. gemma reads the intent right
+85.7% of the time on its own. It loses full accuracy on seven fact keys
+(`вода` instead of `water`, `ужин` instead of `meal`) and on six reminder times
+with no time slot. Stage 0 and the daemon's own extractor repair
+both, which is why the cascade is 28 points higher. The lesson is that the
+cascade earns its keep even under a much better model, not that it is scaffolding
+to remove.
+
+`errors: 6` in the alone row are declines on single-token and ambiguous
+utterances, all of which the cascade caught. The remaining defects through the
+cascade are three `query→fact` confusions, one `chat→query`, and one false
+clarify.
+
+## Talk, 27-case conversational fixture
+
+| | pass | notes |
+|---|---|---|
+| Qwen3-1.7B (31-07) | 20/27 | 11-17/27 for the 0.8B before it |
+| **gemma-4-12b** | **25/27 (92.6%)** | chat 8/9, knowledge 9/9, query 8/9 |
+
+Knowledge is the interesting column: 9/9, in Russian, with real answers about
+Rayleigh scattering, SSD versus HDD and thunder delay. That is the case the
+1.7B cannot do at all and the reason the naming half of the degradation rule
+exists.
+
+Two failures, and one of them is the persona defect the CPT (#122) targets:
+`query-notes-do-not-answer` wrote `заплатил` where Maven needs the feminine
+form. The other is `chat-joke`, where the model told a joke without using any of
+the words the check looks for. Run-to-run variance is about one case: a second
+run scored 24/27 with `chat-followup-server` also off-topic.
+
+## Nudge phrasing, 15-case fixture
+
+15/15, every check, no errors. `mood`, `lang`, `length`, `feminine`,
+`hisgender`, `address`, `cringe` and `ontopic` all clean.
+
+## What this settles and what it does not
+
+Settled: the size question. A 12B on the workstation beats the resident model on
+every fixture we have, and it is faster. The offload argument holds.
+
+Not settled: how often the card is free. That is #485's second assumption and
+only the `mavgpud` log answers it, after a week of the owner's normal work. A
+model that is better whenever it is up is worth little if it is never up.

+# Where the resident model's 7.9GB of RSS goes (2026-08-03, homesrv)
+
+Measured for Vikunja #499. The deployed llama-server held 7.9GB RSS for a 1.1GB
+model file. Half a gigabyte of it was in swap, on a box that also runs
+whisper.cpp, piper and the embedder.
+
+## Method
+
+`maven-mavend-1` was stopped for the measurement, with the owner's approval.
+Its own binary then ran on the host with the exact deployed command line. That
+binary is `/opt/maven/bin/llama-server`, version `1 (4c65955)`, a Vulkan build.
+
+```sh
+llama-server -m /mnt/hdd1/llms/qwen3/Qwen3-1.7B-UD-Q4_K_XL.gguf \
+  --host 127.0.0.1 --port 18099 -c 4096 -ngl 99 --no-webui
+```
+
+RSS was read from `/proc/<pid>/status` after load and after each of 8 distinct
+1521-token prompts. `smaps` of the deployed process was read first, from inside
+the container, since the host user cannot read another user's maps.
+
+## The cause: the prompt cache, not the weights and not the offload
+
+The startup log says it outright:
+
+```text
+srv load_model: prompt cache is enabled, size limit: 8192 MiB
+srv llama_server: n_parallel is set to auto, using n_parallel = 4 and kv_unified = true
+```
+
+The server saves the full KV state of every idle slot it evicts. It keeps up to
+8GiB of those states in host RAM (llama.cpp PR 16391). One saved prompt of 1521
+tokens costs 166.377 MiB. That is 112 kiB per token, exactly Qwen3-1.7B's KV
+footprint (28 layers x 2 x 1024 dims x 2 bytes).
+
+RSS at rest, and per distinct prompt:
+
+| Prompts served | RSS, default | RSS, `--cache-ram 512` |
+|---|---|---|
+| 0 (just loaded) | 443 MB | 411 MB |
+| 1 | 445 MB | 411 MB |
+| 4 | 958 MB | 929 MB |
+| 8 | 1641 MB | 932 MB |
+
+Uncapped, RSS climbs about 170MB per distinct prompt and does not stop until
+the 8GiB limit. Capped at 512 MiB it plateaus at 932MB from the fourth prompt
+on, with the cache holding steady at `3 prompts, 499.132 MiB` and evicting.
+
+The 7.9GB on the running daemon was that climb, weeks of it. Its `smaps` showed
+one 6.03GB anonymous mapping at 5.32GB resident plus a 1.45GB mapping at 1.27GB
+resident, and only 30MB of file-backed RSS.
+
+## The task's leading guess was wrong
+
+`-ngl 99` on the Vega iGPU costs almost no process RSS. A freshly loaded server
+has 95MB of anonymous RSS in total. RADV allocates device memory through the
+kernel, outside the process, and the log sees 8202 MiB free on `Vulkan0`. The
+weights are mmapped and file-backed, so they are evictable and do not pin RSS. The logit buffer is not visible in the numbers above at all.
+
+## Decision
+
+`--cache-ram 512` is now the default, wired as `phraser.cache_ram_mib` and set
+in `deploy/mavend.json`. 512 MiB caps total RSS near 1GB, an eighth of what the
+box carried. It still holds three of the 1521-token probes above. Maven's real
+routing and phrasing prompts are much shorter, so it holds more of those than
+the table suggests. `-c 4096` is untouched, as #499
+required. A negative `cache_ram_mib` passes no flag, for a llama-server too old
+to know it.
+
+Not changed: `n_parallel = 4`. With `kv_unified = true` the four slots share one
+4096-token KV cache, so they do not multiply it.
+
+The other half of #499 was that none of these lines were reachable. mavend
+scraped llama-server's stderr for the listen line and discarded it, and never
+piped stdout at all. Both streams now go to mavend's log with a `llama:` prefix.
+The last 12 startup lines go into the error when the server dies before it
+listens.
+
+## Deployed
+

+# Personal boundary, seed scoring vs possession markers, 2026-08-03
+
+Vikunja #495. `что я говорил про бэкапы?` walked past the personal boundary into
+SearXNG and came back answered from a Habr article. The boundary matched
+possession words only, so a first-person speech verb was not a personal
+question.
+
+## What changed
+
+The boundary now scores the turn's query vector against two frozen seed sets.
+It claims the turn when the personal side is nearer than the world side. Seeds
+and code are in `cmd/mavend/personalboundary.go`. The possession markers stay as
+the offline floor for a handler with no embedder.
+
+A regex speech class was written first and dropped. Russian gives every verb a
+dozen surface forms, and the "как я говорил, ..." preamble list has no end. Each
+form the lexicon missed was one more question reaching the world.
+
+## Measurement
+
+Embedder: multilingual-e5-small int8, the one homesrv runs. Both sides are
+embedded on the query side. Cases are held out, none of them a seed. `make test`
+runs the offline part. The scored part is opt-in through `MAVEN_ONNX_LIB`, like
+`TestONNXRecall`.
+
+    19/19 held-out utterances correct   (TestONNXPersonalBoundary)
+
+    true positive margins   +0.014 to +0.089
+    nearest true negative   -0.005  ("кто такой гагарин")
+
+One case missed during the first pass and is not held out any more: `as i said,
+what is the population of india`, +0.008 to the personal side. It is a world seed
+now.
+
+The gate is the sign of the difference and nothing tighter. The margins are too
+thin for a threshold. The asymmetry favours claiming: a false claim costs one
+honest "не знаю", a false pass sends his life to an upstream engine.
+
+`make eval-recall` unchanged, 18/27 answered at gate 0.55. Recall does not touch
+this path.
+
+## Not verified
+
+The live probe on the deployed box. The daemon was not rebuilt in this session.
+The reply to `что я говорил про бэкапы?` with no matching note is still untested
+against a real SearXNG.

+# Recall topic veto, what it costs and what it buys, 2026-08-03
+
+Vikunja #496. The task asked for a cross-language fix. Skip the topic veto in
+`memory.RecallAllowed` when the question and the hit are in different scripts.
+An English question would then stop losing a Russian note.
+
+No such case exists. No fixture case puts the question and its wanted note in
+different scripts. The case the task named is not one either.
+
+    en-hard-024
+      query  "what fixed the screen problem"
+      note   "the flicker went away once i swapped the display cable"
+
+Both are English. It is a paraphrase failure, not a language failure. A script
+test would not have changed a single case, and neither would a bilingual stem
+map.
+
+## What the veto is worth today
+
+Measured with the real embedder, multilingual-e5-small int8, gate 0.55, margin
+0.008. The first row is the veto as it ships. The second is `RecallAllowed`
+forced to true.
+
+| | cases passing | answered | false recall | silenced by gate |
+|---|---|---|---|---|
+| veto on | 22/32 | 17/27 | 0/5 | 2 |
+| veto off | 22/32 | 18/27 | 1/5 | 1 |
+
+The pass count does not move. The veto trades one true recall for one false one.
+It costs `en-hard-024` and it buys `ru-silent-029`:
+
+    ru-silent-029
+      query  "во сколько отходит поезд"
+      note   "погулял вдоль реки"        0.835, margin 0.019
+
+The second case counted as silenced by the gate is `ru-home-026` at margin
+0.001, which the margin gate stops. The veto has nothing to do with it.
+
+## Why no lexical rule separates the two
+
+`en-hard-024` and `ru-silent-029` are in the same lexical class. Both questions
+share zero content words with their hit, and neither carries a first-person
+marker. The scores sit on top of each other, 0.826 against 0.835, and so do the
+margins, 0.023 against 0.019. Only one thing separates them. A screen problem
+and a swapped display cable are the same event. A train and a river walk are
+not. The embedder scores that difference at nine thousandths.
+
+So the signal is semantic and the gate is lexical. Any rule cheap enough to sit
+in `RecallAllowed` and strong enough to recover `en-hard-024` also re-admits
+`ru-silent-029`, which puts false recall back to 1/5.
+
+One near-miss rule was tried on paper and rejected: let the veto pass when the
+hit itself is first person. It works on these two, because the English note says
+"i swapped" and the Russian note says only "погулял". It is backwards as a
+principle. A first-person note is exactly the personal note the veto keeps away
+from a world question. The rule would weaken the veto where it was designed to
+bite. It survives here only because Russian drops the pronoun.
+
+## Decision
+
+Accept the loss. `en-hard-024` stays silenced and false recall stays 0/5.
+
+The way out is a reranker, not a longer word list. Recall@3 is 85.2% against
+recall@1 at 70.4%, so the right note is usually in the returned set and ranked
+wrong. That is where the remaining points are, and it is not this task.

+# Offloading model work to the workstation
+
+*Last verified: 2026-08-03 @ 12530c8. Living doc: correct it in place, do not append.*
+
+Owner's call, 2026-08-02. Vikunja #483 is the umbrella. Tasks #484 to #487 are the
+work, and this file holds the shape and the rules all four must obey.
+
+## The goal
+
+homesrv cannot grow a GPU. The workstation has 16GB of VRAM. Move the model work
+to the workstation and leave homesrv running the logic that must be always-on,
+deterministic and cheap.
+
+## Why this is tractable
+
+The split already exists structurally. `mavsttd` and `mavttsd` are separate
+daemons that core reaches over a socket, not linked libraries. Moving them off-box
+is a transport change, not a redesign.
+
+The microphone is at the workstation, because that is where the owner sits and
+homesrv is headless. So speech-to-text and the wake word are already on the
+workstation side by construction. Audio never has to cross the LAN. Only the core
+turn does.
+
+## The constraint that shapes everything
+
+The workstation's GPU is often busy: CPT runs, experiments, Correx, the manga-recap
+pipeline. It also sleeps. homesrv does not.
+
+So an offloaded model is never *the* model. It is the preferred one, with a floor
+on homesrv. That is the shape the cascade already has, where a router error falls
+through to the classifier.
+
+## The degradation rule
+
+Two cases, and the line between them is sharp.
+
+**Fall back silently** when the workstation model would only do the job *better*:
+routing, phrasing, a nudge. Falling back costs nothing that exists today, because
+the resident Qwen3-1.7B is today's production quality. The owner should not be told
+that his reply was phrased by the smaller model.
+
+**Name the gap** when the resident model cannot do the job *at all*. A world
+question that a 1.7B answers by inventing is the case. A wrong answer is worse
+than "не могу сейчас". This is the rule CLAUDE.md already states for a sibling
+service being down.
+
+Nothing in between. A turn never breaks on the workstation being asleep.
+
+Both halves are wired, 03-08-2026. `LLMPhraser.PhraseWorld`
+(`internal/phraser/world.go`) is the naming half and has three outcomes, not two:
+
+| State | What he hears |
+|---|---|
+| no `workstation` block | the resident model answers, exactly as before the seam existed |
+| configured, card free | the workstation answers |
+| configured, asleep or busy | the gap, `worldGap` in `cmd/mavend/worldmodel.go` |
+
+The first row is the one worth stating. Naming a gap requires a gap. On a box with
+no second model the 1.7B is the whole product. Refusing every world question there
+would remove a capability the owner has today.
+
+A source holding a passage is on the naming half too: a live search, a ZIM
+article, a page he named. None of them says "не могу сейчас". They read the
+passage back, which is what `phraseSource` returning `""` selects. A real quote
+beats a gap, and neither path invents.
+
+## Admission control, not a scheduler
+
+There is no GPU arbiter. That is a service with its own failure modes, and nothing
+here needs work *distributed*. It needs admission control. The workstation
+advertises free VRAM over a health endpoint, and Maven treats it as one more query
+source that claims a turn or passes. llama-server also refuses to load when VRAM is
+short, so the failure is detectable without cooperation from the owner's other
+jobs.
+
+The caller must be able to ask "is this peer usable right now" without a turn
+hanging on a timeout. A dead remote is a normal state, not an error state.
+`internal/llm.Pair` is that check on the Maven side. A prober caches the answer,
+so `Available()` is an atomic read and no turn pays for a health check.
+
+llama-server does not stay up on the workstation. It cannot: a resident 7-14B
+would hold 16GB against the owner's CPT runs. So a supervisor there owns its
+lifecycle, keeps it loaded while the card is free, and unloads it on idle or
+when another process needs the card (owner's call, 2026-08-02, Vikunja #488).
+
+That supervisor is still not a scheduler, and the distinction is worth holding.
+It arbitrates nothing between callers. It reports whether it can take work and
+manages one process to back that answer. Maven never asks it to start anything
+and never learns that it did.
+
+Contention is decided by presence under `/sys/class/kfd/kfd/proc`, not by a VRAM
+threshold. A ROCm process registers there when it initialises HIP, before it
+allocates anything. So the supervisor sees a contender during that job's startup,
+and yields before the job loses the memory it asked for. A
+threshold reads the card too late. By the time free VRAM has dropped, the other
+job has already lost the allocation race. Free VRAM is still read, but only as a
+precondition for loading, never as the eviction signal. One blind spot is known.
+A job can take the card without registering on the KFD, as a Vulkan or a
+video-decode job would. `describe()` logs every contender's comm, and that log is
+how we find out whether the blind spot is real.
+
+`mavgpud` runs from a systemd unit on the workstation with
+`deploy/mavgpud.json` as its config, and `llama_args` is passed to llama-server
+untouched. The model, the context size, the layer count and the MTP flags are the
+owner's business and not this daemon's schema.
+
+## What stays on homesrv, permanently
+
+The **embedder** (multilingual-e5-small, ONNX, CPU). It backs the classifier, which
+must answer while the GPU is saturated. It is also cheap enough on CPU that moving
+it buys nothing. Four callers:
+
+| Caller | What for |
+|---|---|
+| `internal/router/classifier.go` | the routing floor |
+| `cmd/mavend/actions_query.go` (`queryEmbed`) | memory recall |
+| `cmd/mavend/feeds.go` | ingest embedding for every RSS item |
+| `internal/crawl/watch.go` | ingest embedding for every crawled page |
+
+`internal/speaker` becomes a fifth once it lands.
+
+## Inventory: what runs a model on homesrv today
+
+The **resident model** is one llama-server with seven callers, and 03-08-2026 is
+the date each of them stopped or did not stop being resident-only:
+
+| Caller | What for | Offloaded |
+|---|---|---|
+| `cmd/mavend/voicewire.go` | routing | silently, through `hot` |
+| `cmd/mavend/replier_llm.go` | replies | silently, through `hot` |
+| `cmd/mavend/tick.go` | digestion worker: `PhraseNudge`, `PhraseReminder` | silently, inside the phraser |
+| `cmd/mavend/actions_query.go` | world questions, and any fetched passage | names the gap |
+| `cmd/mavend/capture.go` | capture summarisation (unreachable, see #480) | no, holds its own client |
+| `cmd/mavend/mail.go` | mail extraction (off, no IMAP) | no, holds its own client |
+| `memoryeval.go`, `modelswap.go` | admin and evals | no, and deliberately |
+
+The last three rows are resident-only on purpose. `memoryeval.go` and
+`modelswap.go` measure and swap the resident model, so sending their work
+elsewhere would measure the wrong thing. `capture.go` and `mail.go` are
+background jobs that hold a gated background client (`llmBackgroundClientFor`),
+and that priority has no equivalent on the remote yet. Both are also unreachable
+on this deploy, so wiring them would ship an untestable path.
+
+The `tick.go` row needs one caveat. `phraser.llm_nudges` is `false` in deploy, so
+nudges come from templates and the seam under them changes nothing until that
+flips. It is wired anyway: `PhraseReminder` is on the same transport and is on.
+
+Then the embedder above, **whisper.cpp** in `mavsttd`, and **piper** in `mavttsd`.
+`mavwaked` uses no model at all: an energy-threshold VAD over 30ms frames.
+
+## Order
+
+1. **Transport** (#484). Nothing else is possible until a seam can cross a host.
+   `internal/netaddr` landed in PR #92. A seam address now carries its own scheme,
+   and a scheme-less one is still unix. A tcp seam requires a shared token, because
+   the filesystem permission that authenticated the unix socket is gone.
+2. **The resident model** (#485, #490). Wired. A `workstation` block builds an
+   `llm.Pair` in `modelSeam` (`cmd/mavend/voicewire.go`), routing and replies
+   complete through it, and the phraser holds the same pair (`UseRemote`). Both
+   halves of the rule are live: see the table above for which caller gets which.
+   Measured, `docs/evals/2026-08-02-workstation-gemma4-12b.md`: gemma-4-12b
+   through the cascade scores 84.4% full accuracy at p50 329ms. The resident
+   model scores 72.7% at p50 0.80-1.04s. On the talk fixture it is 25/27
+   against 20/27. Biggest quality delta. A 16GB card runs a 7-14B,
+   which fixes what the 1.7B gets wrong: world knowledge, and the persona the CPT
+   targets. The degradation path is already written and measured, since the
+   classifier scores 68.8% full accuracy at p50 16.6µs on its own.
+3. **Speech-to-text and text-to-speech** (#486). They gain a real margin, but on
+   quality alone, and both already work.
+4. **The wake word** (#487). Independent of all of the above.
+
+## Assumptions
+
+- The LAN is trusted enough that wireguard is supported but not required (owner's
+  call). What crosses the wire is still his utterances. That is why the tcp seam
+  carries its own token instead of assuming a network boundary.
+- The workstation is not expected to be up. Every child task must still serve a
+  turn while it is down.

+failure floor the deploy uses. Do not quote it as the classifier baseline.
+
+Then three things to decide while the numbers are in front of you:
+
+- **319 is done.** 359 gave the LLM path a real confidence signal.
+  `thinSingleToken` was narrowed on 01-08-2026, and agenda questions moved to
+  stage 0. Missed clarify sits at 1 of 6 and false clarifies at 2. Item 2 point 2
+  closed on 02-08-2026: the `make eval-recall` margin sweep is the distribution
+  that was asked for, and `0.008` sits at the knee.
+
+  | delta | answered | false recall |
+  |---|---|---|
+  | 0.005 | 18/27 | 2/5 |
+  | **0.008** | **18/27** | **1/5** |
+  | 0.010 | 16/27 | 1/5 |
+
+  It removes four of five false recalls at no cost in answers, and the next step
+  costs two answers for nothing. The hand-picked value survives on evidence.
 - **278's real ask** is making the eval lab routine rather than building it. It
   is built. Decide whether it runs on a timer, on every merge, or on demand, and
   the task can close.
+- **248** is the memory evaluation loop. It ships, it writes notes, and it cannot
+  speak. `make eval-recall` covers the retrieval half. The open question is whether
+  a written evaluation nobody reads is worth the tick.
+
+**323 is down to one check.** PR #90 covered the spawn path and took phraser
+coverage to 76.9%. Only the 60s startup timeout arm is untested, because testing it
+needs a `StartupTimeout` field on `Config` rather than a test-only hack. While you
+are on the box, time a cold 1.7B load off spinning disk. If it runs near 60s, the
+default is too tight and the field earns itself twice.
+
+Warm, it is nowhere near. A second llama-server answered `/health` 1.8s after
+launch at `n_ctx 4096` on 02-08-2026. That is page cache, so it does not settle
+the question. A cold read needs a cache drop, which needs root.
+
+**`CheckFeminine` has a false positive.** On 02-08-2026 it failed
+`query-notes-do-not-answer` for `ты заплатил`, calling it masculine
+self-reference. Masculine second person is correct, because the owner is male.
+The check matches a masculine
+past-tense verb before `за` without confirming the subject is `я`. Fix it in
+`internal/phraser/eval/checks.go` before trusting a phrasing score to the case.

+**283** is the event intake envelope every reach shares, so a delivery check
+exercises it whether you name it or not. **285** is not verification: the bridge
+framework works and the remaining ask is more adapters. Decide which reach comes
+next, or park it.
+
+Run 02-08-2026. **280 is blocked.** No morning routine is configured (**472**).
+`morning.Item` also has no required-versus-optional field, so behaviour 1 cannot
+hold whatever you configure (**473**). **281's digest gap is closed**, and
+its presence rule passes on inspection. Three of its five items need traffic the
+box has not had. **283 is blocked**: nothing feeds the intake journal. **128
+found the worst defect of the whole session, see below.**
+
+Three of 472's five blockers were cleared the same day, in `deploy/mavend.json`
+and `docker-compose.yml`.
+
+- A `morning_routines` block, one routine `утро` 08:00-11:00 with medicine,
+  water and pets. It is live: the dispatcher logged `dropped morning:утро (sev1,
+  presence=away)`, so the plan builds and the nudge is proposed. 280's
+  behaviours and 128 step 11 are checkable now. 473 still stands.
+- `-ambient-token` on mavweb, value in a gitignored `/.env` that docker compose
+  reads for interpolation. `/api/ambient` answers 401 without the token and 201
+  with it, storing `calendar_event_20260802_Standup`. 283 step 5 and 128 step 8
+  are unblocked. The token is a flag, so it shows in `ps` inside that container.
+  The zenmoney and IMAP secrets are read from files instead. Ingest also
+  reads the notification's wall clock as UTC and stores a 14:30 meeting at 18:30
+  (**482**).
+- `feeds` (two sources), `crawl.on_demand` and `netscan.enabled`. The intake
+  journal now fills: `/events` holds `scan:lan` and `ambient:notif` rows.
+
+Two are not mine to clear. No sibling has a `token` in `deploy/mavend.json`, so
+273 steps 6 and 8 need a credential decision. Nexus has no entities and Praxis no
+attention items, so 272 step 3 needs seed data whose content is the owner's call.
+
+For **285**, two facts bear on the choice. Synapse is already running on this box
+and healthy, so a Matrix reach has a live target and needs no new service. And
+mavweb is already a PWA with a service worker, which 285 itself calls the highest
+value adapter left. Today's reaches are ntfy, telegram and voice.
+
+**Query sources** (**258**, **286**): ask her something the RSS feeds answer and
+something only a ZIM answers, with the search block on. Live search leads and the
+ZIMs are the fallback since 02-08-2026. **286**'s remaining half is doc and
+git ingestion, which is build work, not a check.
+
+**Do not read `/trace` for this.** `/trace` is the nudge-rule trace: rule,
+severity, predicate, gate, selected. No query-source field exists anywhere in the
+codebase. The only evidence of which query source claimed a turn is the
+`voice: search:` and `voice: kiwix:` lines in `docker compose logs mavend`
+(`actions_query.go:589` and `:660`).
+
+Run 02-08-2026, 20 turns. **Search leads and the personal boundary holds.** Every
+world question that reached the boundary was claimed by search. All three
+personal questions produced no search and no kiwix line at all.
+
+The rest of this sitting went badly. **Kiwix has zero live coverage.** SearXNG
+returns four results for everything, including two invented nonsense terms. So
+`querySearch` always claims, and Kiwix is unreachable code as deployed. The ZIM
+half of the 02-08-2026 decision is unverified. A ZIM answer cannot signal a
+silent search failure, because a ZIM answer cannot happen.
+**Ordering defects** in feeds and calendar, plus 258 step 1's utterance not
+working: **474**. And the sitting independently found stage 2 of **470**.
 
 **Tasks and calendar** (**129**, **130**, **127**, **126**, **246**): capture a
 task by voice, confirm it lands, check prioritisation ordering is not nonsense.
 **246** (mail reader) also exercises the `IngestMail` rung that moved to
 `AuthWrite` this morning.
 
+Run 02-08-2026. **129 passes.** The page and the spoken answer agree on ordering.
+The undistinguished task carries no invented reason on either surface, which is
+the thing 129 asks for. **130 fails outright** and **127 half fails**:
+**467**, **469**. **246 cannot be run**: `mavmaild` is commented out in
+`docker-compose.yml` and there is no `email` block, so nothing in steps 4-13 is
+reachable. The `IngestMail` rung does sit at `AuthWrite`
+(`internal/auth/policy.go:96`, asserted in `auth_test.go:421`), verified by
+reading only.
+
 **Routines and patterns** (**43**, **46**, **247**, **254**): these need history
 to detect against. If the database is thin after the outage, they may have
 nothing to propose, which is not a failure. Check `/routines` before
 concluding anything.
 
+Run 02-08-2026. The answer is the middle case: **the detector ran and found
+nothing.** The tick loop is live, and `detectPatterns` is called unconditionally
+at `cmd/mavend/tick.go:227`. It has run about 25 times since the restart. It
+finds nothing because the events table is empty upstream of it. Rows land there
+only from `pattern.Extract` at fact-write time, and `Extract` requires the fact
+value to match a closed 7-action lexicon. All 200 facts on `/history` are
+`page_heartbeat`, `netdata_alarm`, `quiet_hours`, `name`, `service_down` and
+`рост`. Not one lexicon hit, so no event can exist, let alone the four one pair
+needs. **46 step 5 passes**: `/routines` renders `noticed 0` with the empty state
+and the hint string.
+
+Two things block this sitting, and both are build work. The seeding recipe on
+**43** goes through `sqlite3` and cannot work. And `pattern.Detect` has no
+minimum-interval floor, so seeding by hand mints a permanent false routine
+(**468**). Do not try to seed a pattern with four fast chat turns.
+
 **Ecosystem** (**272**, **273**, **276**): nexus, hexis and praxis are wired and
-logged clean at boot. **276** is the degraded-mode suite, which means taking
-siblings down on purpose. Worth doing while you are already in there.
+logged clean at boot.
+
+Run 02-08-2026, read-only half. All three answer `/health` 200 and `/ecosystem`
+lists 18 Hexis capabilities with correct read-only and mutating badges. **272 and
+273 are blocked on empty data**, not on code. Nexus holds no entities, Praxis
+holds no attention items, and the Calls panel has never recorded a call. See
+**472**, and read its warning first. 273's trace fix has never been validated
+here. An empty Calls panel is exactly what the old bug looked like. The page is
+`/ecosystem`, not `/siblings`.
+
+**276 ran 02-08-2026 and the suite is sound.** 17 `TestEcosystem_` cases pass
+under `-race`, not the 10 the task describes. The mutation check bites: patching
+the Nexus-error branch of `handleHexisAct` to `return ""` fails
+`TestEcosystem_MalformedNexusResponseFailsClosed` on the expected line.
+
+Steps 4 and 6 could not be checked through chat, because no utterance reaches
+Praxis (**475**). «что требует внимания» routes to `intent=query` and is answered
+by the search leg, identically whether `ecosystem-praxis-1` is up or stopped. The
+degraded string never appears because its branch is never entered. Step 5 is
+blocked the same way: `перезапусти muzick indexer` clarifies on
+`HasFn:false`, and the router had already rewritten the entity name to
+`музик индексер` (**476**).
+
+Both steps were checked on `/ecosystem` instead, which reads Praxis directly.
+With Praxis stopped the card reads `praxis — unreachable` while Nexus and Hexis
+keep rendering. On `docker start` the card returns to `nothing needs attention.`
+with no mavend restart. Independent degradation and recovery both hold.
+
+**Operations** (**249**, **250**): both ran 02-08-2026. The code is correct and
+neither lever can be pulled on this box. See **477**.
+
+**250** passes steps 1, 2, 3, 9 and 10 on the deploy. The capability announces
+itself. `/models` names the model llama-server reports, not the config filename.
+Asking her to switch models does nothing. Removing `swap_models` renders `swap
+not configured`. Step 4's refusal half passes at HTTP 403, and the 403 comes from
+mavend rather than mavweb. WebAuthn is unconfigured, so the web gate fails open
+and the wire gate fails closed. Steps 5 to 8 need a passkey assertion nothing on
+this box can produce. They pass in test: 13 swap cases and 7 page cases covering
+drain, mid-swap refusal, rollback, failed rollback and the not-owned refusal.
+
+**249** passes steps 1 and 2. Step 3 stops it. `mavupdate` health-checks over
+`/run/maven/mavend.sock`, which is `srw------- 1 10001 999` inside a docker
+volume. The host owner cannot traverse `/var/lib/docker/volumes` and cannot
+connect to a socket owned by an in-container uid. `mavupdate` assumes a
+host-installed daemon and the deploy is containers. Do not sudo around this.

+## Housekeeping (done 02-08-2026, and this section was mostly wrong)
 
-Four QA tasks will not close no matter how long they sit, because they are
-gated on something that does not exist:
+This section claimed eleven tasks were not verification work. **Three were not.
+The other eight are.** Every one of the eight has shipped, tested code behind it.
+The error ran one way: it wrote off work that is ready to check. Do not trust a
+"nothing is built" line in this plan without grepping for the package first.
 
-- **125** zenmoney: needs a token you have not minted.
-- **256** Home Assistant: needs HA configured.
-- **257** Bluetooth: BLOCKED, no bluez on the box. Says so in the title.
-- **288** STT golden audio: needs fixtures generated.
+Relabelled to `Blocked:`, claim verified:
 
-Relabel these so they stop reading as backlog. They are not verification work
-that is pending, they are work that has not started.
+- **125** zenmoney. `internal/zenmoney/` ships and is tested against a fixture.
+  `deploy/zenmoney.token` does not exist and the compose mount is commented out.
+  One token unblocks it.
+- **256** Home Assistant. `internal/smarthome/` ships, the `smarthome` block sits
+  in `deploy/mavend.json` at `enabled: false`, and 8123 and 1883 are closed.
+- **14** cold-start unlock. The seam is real at `cmd/mavend/main.go:128` and
+  `internal/webauthn/prf.go` is in place. `lockedAPI` is gone, replaced by
+  `Server.Check` in `internal/ipc/server.go`. Gated on an authenticator that
+  implements the WebAuthn PRF extension, which is hardware, not code.
 
-Same treatment for the five plan-only tasks (**251** MCP, **252** vision,
-**253** hearing, **255** speaker recognition, **259** crawler). A `QA:` prefix on
-a plan is misleading.
+Left alone, because the claim here was false:
+
+- **284** simulator. `cmd/mavend/simulator_test.go`, three scenarios under
+  `cmd/mavend/testdata/scenarios/`, and a `simulate` target at `Makefile:98`.
+  **Run 02-08-2026: all three scenarios pass**, plus the determinism and
+  backwards-step guards. One defect found, see below.
+- **288** STT golden audio. Four WAVs and `golden_v1.json` are committed under
+  `cmd/mavsttd/testdata/`, the make targets exist, and `models/stt/ggml-small.bin`
+  is on the box. Session 1 lists 288 as blocked on fixtures, which is wrong.
+  **Run 02-08-2026: all four pass**, WER at or under ceiling with no drift.
+
+| fixture | transcript | WER | ceiling |
+|---|---|---|---|
+| ru_reminder | `Напомни мне через час позвонить маме.` | 0.00 | 0.10 |
+| ru_fact | `А отметь, что я выпил воды.` | 0.20 | 0.25 |
+| ru_query | `Что у меня сегодня по календарю?` | 0.00 | 0.10 |
+| en_act | `Restart the web server and check the disk space.` | 0.00 | 0.10 |
+
+That also settles a session 1 worry indirectly: whisper.cpp works on Vulkan
+after the redeploy. Only the mic and the wake path remain unproven.
+
+**The simulator routes with an empty seed set.** Every `make simulate` run logs
+`loaded 0 seed examples from models/seeds`, seven times per scenario. The test
+runs from `cmd/mavend`, and the seed path is relative to the repo root. The
+scenarios still pass, which means they pass without the classifier having any
+seeds to match against. Whatever 284 is proving, it is not proving the routing
+the deploy runs. Fix the path before trusting a green simulator.
+- **257** Bluetooth. The bluez half is genuinely absent. The LAN-scan half shipped
+  (`internal/netscan/`), and steps 1-9 run today. Only step 10 is Bluetooth, so
+  relabelling the whole task would bury real pending work.
+- **251** MCP, **253** hearing, **259** crawler. All three ship
+  (`internal/mcp/`, `internal/capture/`, `internal/crawl/`) with no external gate.
+  Fully checkable. `259`'s step 1 wants no `crawl` block in `deploy/mavend.json`,
+  and there is none, so it is already set up correctly.
+- **252** vision and **255** speaker recognition. Both ship. Each is blocked only
+  on a model download: a vision gguf with mmproj, and a speaker embedding model.
+  Neither is present under `/mnt/hdd1`. Their refusal-path steps run today.
+
+So the honest split is three blocked on a credential or hardware, two blocked on
+a download, and six ready to check. That is roughly a session of real QA this
+plan had written off as backlog.
+
+**All six ran on 02-08-2026.** Every one of them is code-correct and stops at the
+deploy. The pattern repeats often enough to be the headline: the packages pass,
+and the box cannot reach them.
+
+**251, MCP.** Steps 1, 2, 3, 4 and 13 pass. Package tests green under `-race`.
+Off-by-default is clean, and the SSRF refusal is exact: without `allow_private`
+the log reads `refusing to connect to a private address: 127.0.0.1` and `/tools`
+shows the server down with zero proposals. Steps 5 to 12 are blocked. `ss -lntp`
+shows the Vikunja MCP server on `127.0.0.1:9100` only, so no container reaches it
+at any address (**478**). `allow_private` does work, measured both ways.
+
+**253, hearing.** Steps 1, 2 and 17 pass. `internal/capture` covers 90.3%. Steps
+7 to 16 are blocked on something nobody can work around: no shipped client calls
+`CaptureStart`. There is no `cmd/mavheard`, no mavweb route, and `mavenclient`
+never calls it (**480**). Two of its QA steps are also stale.
+
+**257, netscan.** Steps 2, 3 and 9 pass at unit level. Step 1 fails. Steps 4 to 8
+need the block enabled. Step 10 is Bluetooth and stays skipped.
+
+**259, crawler.** Steps 1 and 15 pass. Step 2 fails. Steps 3 to 14 need a `crawl`
+block that nobody has written.
+
+Both were configured later the same day, and both work. `netscan.enabled: true`
+answers `какие устройства в сети?` with `нашла 3 устройства, из них 2 с вебом, 2 с
+ssh. список записала.` and the scan lands in the intake journal as `scan:lan`.
+`crawl.on_demand: true` answers `посмотри https://lwn.net — что там пишут?` from
+the real page. So **479** is one defect, not the routing defect it was filed as.
+An unconfigured capability declines its own turn instead of naming the gap.
+Nothing is wrong with the routing.
+
+257 step 1 and 259 step 2 fail the same way and share a task (**479**). An
+unconfigured capability does not name the gap, so the question escapes to web
+search. `какие устройства в сети?` was answered with a general article about
+network hardware. That is his LAN going to an upstream engine.
+
+**252 vision and 255 speaker.** Both confirmed blocked. The disk claim was
+re-verified rather than taken on trust: 16 text-only ggufs under `/mnt/hdd1`, no
+mmproj and no speaker embedding model. Everything not needing the model passes,
+including the two refusals that matter. `TestNewLocalRefusesNonPrivateEndpoints`
+rejects `https://api.openai.com`, and forget really deletes
+(`internal/store/memory.go:145` is a real `DELETE`, not a tombstone). Vision is
+19/19, speaker 22/22, media 16/16.
+
+**470 got worse, then closed.** Both poisoned facts showed `voided` on
+`/history` and the defect survived. Re-measured at 15:42, after four restarts:
+`почему небо синее?` still answered `какая последняя версия языка Go?` with no
+`search:` line. What came back was the question he typed, not the value the fact
+held. So the poison was a vector in the memory index, and `revert` did not
+remove it.
+
+Repaired in two parts. 470 stopped the writes: a question is never a fact, and a
+void drops the key's vectors. 493 fixed what the index holds. A fact is indexed
+as the fact and not as the utterance, and a correction drops its superseded
+vector too.
+
+A poisoned box now repairs itself on the next start. `RepairFactVectors`
+re-embeds every fact vector from the fact it names, and deletes the voided and
+superseded ones. It runs once, guarded by a marker, and logs what it did.
