Response-quality work, all aimed at giving the model enough context to
answer accurately:
- Every chat's system prompt now carries a live library map (today's
date, counts, and the exact names of channels, domains, zims, and
inventories, capped and cached 60s). Exact spellings are in context
before the first token, and the list_collections round-trip — minutes
on slow hardware — is usually unnecessary.
- The request is budgeted against the model's real context: oldest
turns are trimmed first, the current question is never dropped, and
an over-budget turn gets a clear "start a new conversation" error
instead of a silently truncated prompt. cache_prompt reuses the KV
cache for the stable prefix, which is most of the latency on a Pi.
- context_size plumbing fixed: selecting a model adopts its catalog
default (the 4B was running at 8k instead of 16k), and llama-server
runs --parallel 1 so the single user gets the whole context.
- temperature is configurable in ai.yaml (default 0.3 — small models
call tools far more reliably near 0.2-0.3 than at server defaults).
- One worked tool-use example per mode is prepended to every
conversation; small models imitate far better than they obey.
- scripts/ai_eval.py scores the assistant against a live WROLPi on
mechanical checks (finished, called the right tool first, included a
WROLPi link, no external URLs) so prompt changes stop being validated
by anecdote.

ai.yaml is the source of truth (opt-in: enabled=False by default) with
active model, idle-unload minutes, context override, and tool-call
bound. The model catalog follows the map pattern: a bundled constant
keeps the Manage tab working offline, the CDN manifest (ai/models.json
+ detached GPG signature) wins when reachable. GGUF downloads clone
the map-extract flow — the per-file meta4 is GPG-verified once and the
same bytes handed to aria2c, so the verified hash is the enforced one;
unverified downloads are refused. Models land in <media>/ai/models/
(gated by the existing media_mounted download rules). Manage endpoints
(catalog with RAM-tier recommendation, settings) live under
/api/ai/manage/ which the future agent loop excludes from its tool
catalog.
