feat(kb): add kb-query service skeleton (search API, no ingress yet)
Module 5 phase 4 step 1 (docs/kb/modules/05-faza4-plan.md, §4): first
user-facing HTTP entry point to the KB. FastAPI wrapping
kb_retrieval.cascade_query/flat_query — GET /search (query_text -> embed via
Ollama@SOLARIA -> cascade/flat -> envelope join -> JSON with per-source
links) and GET /healthz. Search API only, no answer synthesis (phase 5) and
no server-side dist filtering — the 0.45/0.55 colour thresholds are a
frontend concern (plan §7, a later step).
Hard startup invariant (plan §2 decision 2): refuses to start unless the
configured EMBED_MODEL is present in both document_chunk.model and
document_summary.embedding_model. Note the latter: document_summary.model is
the LLM that *wrote* the summary (claude-haiku-4-5/gemma3:12b), not the
embedder — checked live against kb-postgres@PIHA before writing this, see
app/startup.py's docstring. Verified end-to-end with a live docker run: the
invariant crash-loops on a mismatched EMBED_MODEL and passes through to a
real /search hit against the live corpus with a correct model.
Repo-only: no deploy, no npm/OIDC/DNS wiring (plan §8, later step), no local
embed fallback (plan §5, later step) — Ollama@SOLARIA is called directly and
a failure surfaces as 503, not a crash.
Also: scripts/deploy/deploy.sh's gate now builds each service via
`docker compose build` instead of a raw `docker build <svc_dir>`, so a
service whose docker-compose.yml declares a repo-root build context (needed
here to COPY packages/kb-retrieval/, the packages/ Dockerfile convention
already documented in CLAUDE.md) resolves the same way in the gate as it
does at real deploy time (deploy-node.sh's `docker compose ... up --build`).
No behavior change for existing single-context services — verified against
llm-gateway's compose file.

service :
name : kb-query
owner_node : piha
feat(kb-query): add search frontend (module 5 phase 4, plan §7, Krok 4)
Krok 4 of the phase-4 plan done ahead of the local-embed-fallback step
(Krok 2, deliberately deferred -- embed stays a plain SOLARIA call, per
task instruction): one FastAPI process now serves both the /search API
and the UI, no separate frontend build (plan §2 decision 4).
- GET / renders a Jinja2 shell; app/static/app.js (vanilla, no build) and
style.css are the whole client. Query -> /search, results grouped by
envelope_id client-side (chunks sorted by dist, <details> fragments).
- Colour thresholds per plan §7: dist<0.45 green, 0.45-0.55 yellow (still
shown with a warning), >0.55 never rendered as an individual result; if
a query ends up with nothing renderable, one "Brak odpowiedzi w KB"
message replaces the list, carrying the best observed dist.
- Paperless hits link out; gmail hits get a "kopiuj Message-ID" button
(there's nothing to link to yet, plan §2 decision 3) plus header
metadata. Cascade/flat toggle defaults to cascade. Footer shows
sol_status, refreshed from /healthz on load and after each search.
- /search gained additive summary/summary_tags fields (document_summary,
haiku track) so the UI can show a document summary as each result
group's header -- non-breaking, existing response shape untouched.
- Tests: app/db.py + app/search.py unit tests (mocked DB/HTTP, no live
deps) cover the new summary join; tests/test_frontend.py drives GET /
and /static/* via TestClient without running the DB-requiring lifespan;
tests/frontend/app.test.js (Node's built-in test runner, no framework)
covers query-URL encoding, threshold colouring, and envelope grouping.
- Verified live: docker build + container against kb-postgres@PIHA over
LAN and Ollama@SOLARIA over Tailscale -- GET / (HTML), /static/app.js,
/healthz, and /search (cascade + flat) all round-tripped correctly,
including real summary/summary_tags data.

feat(kb-query): active embed fallback SOLARIA→PIHA (module 5 phase 4, plan §2/§5)
Last missing core piece of KB phase 4: kb-query no longer hard-fails /search
when Ollama@SOLARIA is unreachable. app/fallback.py implements the plan's
circuit-breaker exactly (30s cached health probe, 3s hard embed timeout on
SOLARIA, one-shot same-request switch to a new local ollama-piha@PIHA
container on timeout/error). sol_status in /healthz and /search now reflects
the real breaker state instead of a hardcoded "up".
New services/ollama-piha (bge-m3, OLLAMA_KEEP_ALIVE=0, arm64/no-GPU) is the
local fallback leg. Live calibration on PIHA (2026-07-27, normal load):
embed latency 4.2-5.2s, RAM peak ~983MiB against a 2.5GiB ceiling -- both
inside the plan's go-bar, so the fallback is enabled by default rather than
gated behind a flag. Calibration also surfaced and disabled (not removed) a
previously-undocumented orphaned native ollama.service on PIHA that had been
conflicting with the container's port.
The embed-model invariant (query embedding == document_chunk.model) still
enforces once at startup, since both fallback legs share one EMBED_MODEL
constant by construction; a redundant per-request DB check was deliberately
skipped and the invariant is instead proven structurally by test.
retrieval_eval.py gains --transport http (plan §2 decision 6/§9), previously
unimplemented. Verified live: HTTP transport is bit-identical to direct
transport against the same live SOLARIA (0 mismatches), and a live sol-down
simulation (kb-query's own OLLAMA_URL pointed at a dead address, no other
Ollama consumer touched) shows the PIHA fallback answering with the same
hit@3 gate outcome and dist within ~3e-4 of the SOLARIA baseline.
Zero changes to DB schema or kb_retrieval's retrieval logic -- only the
embed + health layer, per task constraints.
