126 plikow (md, yaml, sh, py) odwolywalo sie do sciezek sprzed migracji.
15 markdown-linkow [..](..) -> policzona sciezka WZGLEDNA wobec pliku
odsylajacego (wczesniej czesc z nich byla repo-root-relative i nie
rozwiazywala sie z katalogu, w ktorym lezala)
200 odwolan tekstowych (backticki, proza, yaml, importy w kodzie)
-> nowa sciezka repo-root-relative, zgodnie z konwencja repo
5 linkow rodzenstwa (gole nazwy plikow, np. "](DEPLOY.md)") — dzialaly
tylko w starym katalogu; przeliczone recznie
Objete m.in.: CLAUDE.md (scripts/onboard/README.md -> kb/runbooks/
node-onboarding-tool.md, docs/backlog.md -> kb/phases/backlog.md),
README.md, .claude/skills/, 20 session logow, kod jobow.
Ostatnie 5 odwolan pochodzi z tresci wciagnietej rebasem z origin/master
(session log 2026-07-31, override node-agenta na SOLARII, dwie pozycje
backlogu) — wskazywaly na docs/incidents/, docs/kb/modules/ i
services/narty27/README.md sprzed migracji.
Dodany wzajemny link miedzy kb/services/control-plane.md (stub kodu)
a kb/subsystems/control-plane.md (opis, deprecated) — dwa dokumenty o tym
samym systemie, latwe do pomylenia.
Weryfikacja na 790 plikach: 0 odwolan do starych sciezek,
0 martwych linkow markdown. Lint OKF: 190/190 plikow ZGODNE.

# kb-query
|
||
|
||
FastAPI search API in front of the module-5 KB retrieval engine
|
||
(`packages/kb-retrieval/`). Runs on **PIHA**, bound to PIHA's LAN IP only
|
||
(`exposure: private`, same class as paperless/nextcloud — no public ingress
|
||
yet). This is a **search API, not chat**: no answer synthesis over results,
|
||
that's phase 5.
|
||
|
||
## Endpoints
|
||
|
||
| Endpoint | Method | Purpose |
|
||
|---|---|---|
|
||
| `/` | GET | Search UI (Jinja2 shell + `/static/app.js`, no login yet — plan §8 OIDC is a later step) |
|
||
| `/static/*` | GET | UI assets (`app.js`, `style.css`) |
|
||
| `/healthz` | GET | `{"status": "ok", "sol_status": "up"\|"down", "fallback_status": "up"\|"down"\|"unconfigured"}` — `sol_status` comes from the embed router's ~30 s-cached SOLARIA probe (same world view `/search` routes by), `fallback_status` is a live cheap probe of ollama-piha; no auth required (monitoring must reach it) |
|
||
| `/search?q=<text>&mode=cascade\|flat` | GET | `query_text -> embed -> cascade_query/flat_query -> results`, `mode` defaults to `cascade` |
|
||
|
||
`/search` response shape (module 5 phase 4 plan §4, `summary`/`summary_tags`
|
||
added in Krok 4 for the UI's per-envelope result header — additive, does not
|
||
change any field the plan §4 shape already defined):
|
||
|
||
```json
|
||
{
|
||
"query": "...", "mode": "cascade", "sol_status": "up", "embed_backend": "solaria",
|
||
"results": [
|
||
{"envelope_id": "paperless:119", "source": "paperless", "dist": 0.34,
|
||
"chunk_index": 2, "text": "...", "link": "https://paper.kapala.org/documents/119/details",
|
||
"summary": "...", "summary_tags": ["..."]},
|
||
{"envelope_id": "<Message-ID>", "source": "gmail", "dist": 0.44,
|
||
"chunk_index": 0, "text": "...", "subject": "...", "from": "...", "date": "...",
|
||
"link": null, "mail_ui_url": null, "summary": null, "summary_tags": []}
|
||
]
|
||
}
|
||
```
|
||
|
||
`dist` is never filtered server-side — the 0.45/0.55 colour thresholds (below)
|
||
are a frontend concern, not an API contract. `summary`/`summary_tags` come
|
||
from `document_summary` for `SUMMARY_MODEL`; `null`/`[]` when the envelope
|
||
has no summary yet.
|
||
|
||
## Frontend (Krok 4, plan §7)
|
||
|
||
One page, served from this same FastAPI process — no separate frontend
|
||
container, no node build step (plan §2 decision 4): `app/templates/index.html`
|
||
(Jinja2 shell) + `app/static/app.js` (vanilla JS, `fetch()` to `/search`) +
|
||
`app/static/style.css`. Wszystko po polsku.
|
||
|
||
- Pole zapytania + submit (Enter lub przycisk), przełącznik trybu
|
||
kaskada/flat (domyślnie kaskada — checkbox "tryb flat (debug)").
|
||
- Wyniki grupowane po `envelope_id` (dokument): nagłówek trafienia to
|
||
streszczenie dokumentu (`summary`, tor haiku) gdy dostępne, w przeciwnym
|
||
razie `envelope_id`; chunki są rozwijanymi fragmentami (`<details>`) pod
|
||
nagłówkiem, posortowane po `dist`.
|
||
- Kolorowanie progów (fazy 3, zweryfikowane bramką): `dist < 0.45` zielony,
|
||
`0.45–0.55` żółty (nadal renderowany, z wizualnym ostrzeżeniem), `> 0.55`
|
||
nigdy nie renderowany jako pojedynczy wynik. Jeśli po tym filtrze żadna
|
||
grupa nie zostaje nic do pokazania (wszystkie trafienia > 0.55, albo brak
|
||
trafień w ogóle), całość zastępuje komunikat "Brak odpowiedzi w KB dla
|
||
tego zapytania" z najlepszym (najniższym) zaobserwowanym `dist` w nawiasie.
|
||
- Źródło: Paperless → link "Otwórz w Paperless" (`link`); Gmail → metadane
|
||
(`subject`/`from`/`date`) + przycisk "Kopiuj Message-ID" (`envelope_id`
|
||
**jest** Message-ID, plan §2 decyzja 3) — nie ma dokąd linkować, więc
|
||
kopiowalny identyfikator zamiast martwego linku.
|
||
- Stopka pokazuje `sol_status` dyskretnie (odświeżane z `/healthz` przy
|
||
starcie strony i po każdym wyszukiwaniu).
|
||
|
||
## Embed path — active SOLARIA→PIHA fallback (Krok 2, plan §2 D2/§5)
|
||
|
||
Query embeddings go through `app/embed_router.py` (`EmbedRouter`, one instance
|
||
per process):
|
||
|
||
1. SOLARIA's health verdict (`GET /api/tags`, 1.5 s timeout) is **cached for
|
||
30 s** — no per-request probing.
|
||
2. Verdict `up` → embed on `EMBED_PRIMARY_URL` (SOLARIA GPU, ~207 ms) under a
|
||
hard 3 s timeout.
|
||
3. A failure **during a real embed** flips the verdict to `down` for one TTL
|
||
window and the **same request** is served from `EMBED_FALLBACK_URL`
|
||
(`ollama-piha`, CPU, `OLLAMA_KEEP_ALIVE=0` — slower, single seconds, but
|
||
alive) — the user never sees a SOLARIA error while a fallback exists.
|
||
4. Verdict `down` → straight to the fallback until the TTL expires; when
|
||
SOLARIA wakes up, traffic returns to the GPU within ≤30 s.
|
||
|
||
Every `/search` response and log line says which backend embedded the query
|
||
(`embed_backend: "solaria"|"piha"`, log `backend=…` in `kb-query.embed`) —
|
||
needed to debug result quality per backend. `sol_status` in the response is
|
||
the router's world view; the UI footer renders `down` as
|
||
„SOLARIA: offline (fallback embed)".
|
||
|
||
**Model invariant, both halves:** at startup kb-query pins `EMBED_MODEL`
|
||
(bge-m3) to `document_chunk.model`/`document_summary.embedding_model` (below);
|
||
additionally each backend is verified once, at its first use, that its
|
||
`/api/tags` actually lists `EMBED_MODEL`. A backend serving the wrong model is
|
||
a **loud ERROR + 500** — never a silent distance computation across two
|
||
different embedding spaces. Verification is lazy because SOLARIA may be asleep
|
||
at boot and must not block startup.
|
||
|
||
`/search` returns **503** only when BOTH backends are unreachable (or
|
||
`EMBED_FALLBACK_URL` is unset — then the pre-fallback behaviour applies);
|
||
`/healthz` still answers, same tolerance pattern as `llm-gateway`.
|
||
|
||
## Startup invariant (hard-fail)
|
||
|
||
At startup, kb-query queries `document_chunk.model` and
|
||
`document_summary.embedding_model` for the set of models behind *active*
|
||
embeddings, and refuses to start (crash-loop, visible via container restarts)
|
||
if the configured `EMBED_MODEL` (default `bge-m3`) isn't in both sets. This
|
||
guards against querying with an embedding space that doesn't match what's
|
||
actually indexed — see `app/startup.py` for why the check reads
|
||
`document_summary.embedding_model` and not `.model` (the latter is the LLM
|
||
that *wrote* the summary, e.g. `claude-haiku-4-5`, not the embedder).
|
||
|
||
## Configuration
|
||
|
||
`.env` — **gitignored**, copy from `env.example`. Required: `LAN_BIND_IP`,
|
||
`KB_DSN`. On PIHA also set `EMBED_FALLBACK_URL=http://192.168.31.5:11434`
|
||
(ollama-piha). Optional (defaults in parentheses): `EMBED_PRIMARY_URL`
|
||
(`http://solaria:11434`), `EMBED_PRIMARY_NAME`/`EMBED_FALLBACK_NAME`
|
||
(`solaria`/`piha`), `EMBED_HEALTH_TTL_S` (30), `EMBED_HEALTH_TIMEOUT_S` (1.5),
|
||
`EMBED_PRIMARY_TIMEOUT_S` (3), `EMBED_MODEL` (`bge-m3`), `SUMMARY_MODEL`
|
||
(`claude-haiku-4-5`). `OLLAMA_URL` was **renamed** to `EMBED_PRIMARY_URL` in
|
||
Krok 2 — if an old `.env` sets `OLLAMA_URL`, it is ignored.
|
||
|
||
## Ingress (`kb.kapala.org`, plan §8)
|
||
|
||
Wired up 2026-07-23 (`docs/sessions/2026-07-23-kb-f4-ingress.md`), **no code
|
||
change in this service** — pure infra step:
|
||
|
||
- npm@PIHA proxy host #35: `kb.kapala.org` → `http://192.168.31.5:8230`,
|
||
cert #49 (`*.kapala.org` wildcard, DNS-01 via Cloudflare, expires
|
||
2026-09-28) — same pattern as `paper.`/`vikunja.`/`ha.kapala.org`.
|
||
- Pi-hole Local DNS (`/etc/pihole/custom.list` on PIHA, runtime, not in Git):
|
||
`kb.kapala.org` → `192.168.31.5`. **This is the first `kapala.org` entry in
|
||
that file** — every other `kapala.org` vhost (paper/ha/immich/vikunja/forgejo)
|
||
has no LAN override and resolves via the public Cloudflare record
|
||
(Tailscale IP) even from LAN, a hairpin the plan assumed was already avoided
|
||
for those too. Not fixed here (out of this task's scope — no other vhosts
|
||
touched); worth a follow-up if it matters for those services.
|
||
- Cloudflare A record `kb.kapala.org` → `100.108.208.3` (Tailscale PIHA, DNS
|
||
only): added manually by the operator (no CF API token available in the
|
||
environment that did the rest of this step), verified against Cloudflare's
|
||
own authoritative NS and 8.8.8.8/1.1.1.1 — resolves everywhere now, both
|
||
LAN (via Pi-hole override) and Tailscale/public (via this record).
|
||
|
||
**No auth.** OIDC (plan §8: `authlib`, `/login`, `/auth/callback`) is explicitly
|
||
**not implemented** — confirmed no forward-auth/reverse-proxy-level auth pattern
|
||
exists anywhere in this repo (NPM community edition doesn't support it either);
|
||
the three precedents (paperless/nextcloud/vikunja) all do OIDC inside the app.
|
||
Building that is real service code (`authlib` dependency, session middleware,
|
||
Forgejo OAuth2 app registration) — deliberately deferred to a separate session,
|
||
decision confirmed with the operator 2026-07-23. Until then `kb.kapala.org` is
|
||
reachable by anyone on the LAN/tailnet with no login, same as before this vhost
|
||
existed.
|
||
|
||
## Out of scope for this step
|
||
|
||
- OIDC login (see above) — separate session, needs `authlib` + Forgejo OAuth2 app.
|
||
- Calibration verdict for the fallback (plan §5 steps 4–5: live PIHA
|
||
measurements → keep/tune/degrade decision) — the mechanism is built and
|
||
default-on when `EMBED_FALLBACK_URL` is set; the measurements are the
|
||
operator's post-deploy step (see `kb/services/ollama-piha.md`).
