+# CRM association proof (oo CLI ↔ corpus)
+
+Proven with `oo` (eslider/go-onlyoffice) against the OnlyOffice portal
+(`office.produktor.io`). Portal CRM is the SSOT for company ↔ person ↔
+project associations; the corpus SoT (`eslider/cv/projects/knowledge-mesh-seed.yaml`)
+is the second, independent source. Facts that can be backed by both are
+written to the brain under `root=facts` by `bin/facts/crm`.
+
+## What was verified
+
+- Logical counts (portal MySQL): 1300 contacts = 897 persons + 404 companies,
+  198 projects, 998 deals, 939 project↔contact links.
+- Every client company linked to a project has ≥1 person underneath.
+- Every person `company_id` resolves to an existing company.
+- Corpus org list (9) maps 1:1 onto CRM companies:
+  ProProdukt SL / produktor.io, Dyvenia, Immowelt AG, WhereGroup,
+  Keynote SIGOS, D2S/SYSTEMS, GRID, Pack und Cup, Markets Platform.
+- 78 person↔company association facts written to the brain
+  (`how=crm-crosscheck`, `type=association`). Recall@5 in `bin/kb/eval` = 1.0.
+
+## Mistakes found
+
+| # | Mistake | Fix |
+|---|---------|-----|
+| 1 | Duplicate legal entity `GoldenRatio.Exchange` (contact 759) vs `Golden Ratio Exchange` (763); 3 deals (211, 287, 559) were linked to 759 | `oo contacts merge 759 763` — 763 kept, 759 removed, deal links re-pointed to 763 |
+| 2 | `env/`-wide: OnlyOffice creds file used wrong UX (user `eslider`, password with `$2` suffix) making `oo` auth fail | `.env` fixed to `eslider@gmail.com` + clean password; `.env` stays gitignored |
+
+## Gates after fix
+
+- `uv run python -m unittest discover -s bin/tools -t .` → 26 tests OK
+- `bin/facts/audit self` + `bin/facts/audit db` → ok
+- `bin/kb/eval` → recall@5 = 1.0
+- `go test ./...` (bin/server + bin/watch) → ok

-| Quality 27B (full) | `Qwen/Qwen3.6-27B` | not pulled on this CPU box |
-
-There is **no official Qwen3.6-9B**. Do not invent that id.
-
-Qwen3.5-9B has documented upstream tool-call XML bugs. A 9B win on tools
-is only claimed if this bake-off records OpenAI `tool_calls` (not
-`<tool_call>` XML in `content`).
-
-The 2dph API image does not `COPY` GGUF/safetensors. Pull at runtime into
-the `reasoner-ollama` volume.
-
-## Live CPU run
-
-Host sidecar: Ollama **0.32.9**, `OLLAMA_NUM_GPU=0`, `127.0.0.1:11435`,
-`device: cpu`, `vram_mb: 0`. Date: 2026-08-13. Same three prompts
-(`search` / `get` / `audit`). PicoClaw binary was not used; the OpenAI
-tools payload is the surface it would send.
-
-| Model | HF id | tool_call | xml_leak | rss_mb | latency_ms (search/get/audit) |
-|-------|-------|-----------|----------|--------|-------------------------------|
-| `qwen3.5:9b` | `Qwen/Qwen3.5-9B` | 3/3 | 0 | 5790 | 50059 / 51678 / 31980 |
-| `MichelRosselli/bonsai-27b:Q1_0` | `prism-ml/Bonsai-27B-gguf` | 3/3 | 0 | 21951 | 327702 / 166830 / 119808 |
-| `Qwen/Qwen3.6-27B` | `Qwen/Qwen3.6-27B` | not loaded | — | — | too heavy for this CPU box |
-
-Both loaded models emitted OpenAI `tool_calls` (not `<tool_call>` XML) on
-this runtime. **Do not claim 9B is better at tools** — the score is tied
-at 3/3. 9B is smaller and faster. Bonsai RSS includes weights + KV

-# Gap to v1 — detective brain
-
-Goal: a brain that does not assert without proof. Search is deduction
-(`facts` ≥2 sources → `info` → `web`). `confirmed` only from the facts root.
-
-**v1 is a living graph the agent can write and walk**, not “more RAG”.
-
-Epic: [Gitea #16](https://git.produktor.io/eSlider/2dph/issues/16).
-Milestone: [v1 detective brain](https://git.produktor.io/eSlider/2dph/milestone/12).
-Decisions: [PLAN.md](../PLAN.md).
-
-## In (do not reopen)
-
-Read path Go + Zig CGO (D21). HTTP + OpenAPI + MCP (D20). PicoClaw compose
-profile + CPU reasoner (D18). Mail sync → import → rebuild. D14 shebangs.
-Compose `api` (no CPython) / `index` (Python write). Issues #1–#5, #7–#13.
-
-`POST /ingest` is a rebuild **hint**. `add` is not implemented.
-
-## Blockers
-
-```
-question
-    │
-    ├─ FTS + HNSW          ← in

-    ├─ web (D17)           ← in
-    ├─ Cypher hop          ← #17  schema yes, search no
-    ├─ brain/add ACID      ← #14  rebuild only
-    └─ facts+chats corpus  ← #18
-```
-
-1. **[#14](https://git.produktor.io/eSlider/2dph/issues/14) write** —
-   `bin/brain/index.go --rebuild` (Python `kblib`). No incremental
-   `brain/add`. Watch/mail/git cannot become facts “now”.
-2. **[#17](https://git.produktor.io/eSlider/2dph/issues/17) hops** —
-   `Leaf-[:FROM_FILE]->File-[:HAS_VERSION]->Commit-[:AUTHORED]->Person`
-   exists; `--hop` still errors. Without a walk, D9/D10 are paper.
-3. **[#18](https://git.produktor.io/eSlider/2dph/issues/18) corpus** —
-   rebuild loads repo markdown + mail as `info`. `facts/extract` pairing
-   and `bin/chats` are not indexed. WhatsApp is a stub. PII stays in `var/`.
-4. **[#15](https://git.produktor.io/eSlider/2dph/issues/15) lever/loop** —
-   2dph is the lever (`search` → `get` → `audit`). PicoClaw is the loop.
-   Document the contour in-repo; CPU turns need a large context window.
-5. **[#19](https://git.produktor.io/eSlider/2dph/issues/19) CI eval** —
-   recall SoT should be `bin/brain/eval.go` via Zig, not Python `bin/kb/eval`.
-
-## Not v1
-
-[#6](https://git.produktor.io/eSlider/2dph/issues/6) OCR (OQ2), OQ1
-contradiction resolution, OQ3 duckdb-md export, OQ4 YAML-first leafs.
-
-## Close epic #16 when
-
-- facts+info can be written without a full rebuild for every leaf
-- `--hop` stops erroring and runs a Cypher path from search hits
-- ops pairing + chat import land as leafs on rebuild
-- MCP tool order is documented and still gated by tests

-# Run 2dph (portable)
-
-No laptop-absolute paths. Config lives in env files under `$HOME/.config/brain/`
-(mode 0600), not in git.
-
-## Toolchain
-
-- Go (see `go.mod`)
-- Python 3.12 + [uv](https://docs.astral.sh/uv)
-- Optional: Docker, Zig CGO via `bin/cgo/zig` (not gcc)
-
-```bash
-uv venv .venv
-uv pip install -r requirements.lock.txt
-eval "$(bin/cgo/zig env)"   # when compiling Ladybug read tools
-go test ./...
-uv run python -m unittest discover -s bin/tools -t .
-```
-
-## Config
-
-| File / env | Purpose |
-|------------|---------|
-| `$BRAIN_SEARCH_ENV` (default `$HOME/.config/brain/search.env`) | `BRAIN_SEARCH_URL` (SearXNG). Optional Basic Auth. |
-| `$HOME/.config/brain/db-profiles.yml` | read-only Postgres profiles (OnlyOffice via tunnel) |
-
-If the host already runs SearXNG, point `BRAIN_SEARCH_URL` at it. Do not start
-a second copy (D3). Optional Compose instance:
-
-```bash
-SEARXNG_SECRET=$(openssl rand -hex 32) docker compose --profile searxng up -d
-```
-
-That binds `127.0.0.1:8888`. JSON format must stay enabled.
-
-## Index then search
-
-Write path is Compose profile `index` (Python Ladybug rebuild) until
-`brain/add` is v2. The operator command is `bin/brain/index.go`.
-
-```bash
-bin/brain/index.go --rebuild
-bin/brain/search.go "LadybugDB vector index"     # facts → info → web (D17)
-bin/brain/search.go "upstream flag" --no-web
-bin/brain/get.go <id> --body
-bin/brain/stats.go
-```
-
-`--hop` is not implemented. Empty web results are `throttled`, not absence.
-Gap to v1: [roadmap](roadmap.md) / [epic #16](https://git.produktor.io/eSlider/2dph/issues/16).
-
-Ladybug 0.19: never `DROP INDEX` FTS/VECTOR (ghost catalog). Fresh indexes =
-delete `var/kb.lbug` then `--rebuild`.
-
-## HTTP / MCP
-
-```bash
-docker compose up -d brain                       # :8630 Zig CGO serve
-docker compose --profile index run --rm index    # rebuild
-docker compose --profile picoclaw up brain-mcp   # MCP 127.0.0.1:8630
-```
-
-`GET /openapi.json`, `POST /mcp`. Agent tool order: `search` → `get` → `audit`.
-
-## Reasoner (optional, D18)
-
-CPU sidecar on `127.0.0.1:11435`. Weights are not in the 2dph image.
-
-```bash
-docker compose --profile reasoner up -d reasoner
-REASONER_BASE_URL=http://127.0.0.1:11435/v1 ./bin/reasoner/bakeoff.go --json
-```

-```bash
+- The default engine set for the `general` category is only `duckduckgo`,

+  `Suspended: too many requests` or `Suspended: CAPTCHA` almost permanently, so
+  in practice a single engine carries every query.
+- About 25 probe requests over a few minutes pushed `duckduckgo` into `CAPTCHA`
+  as well. The instance then answered HTTP 200 with `results: []` and an empty
+  `unresponsive_engines` - indistinguishable from "nothing found" without the
+  client-side handling we added.
+- Recovery took roughly six minutes.
 
-Pinned image: `docker.io/searxng/searxng:2026.8.10-0a118066d`.
+## Changes
-Settings: `deploy/searxng/settings.yml` + `limiter.toml` (RFC1918 `pass_ip`,
-short `suspended_times`, `formats: [html, json]`). No secrets in git. Bind is
-`127.0.0.1:8888`.
 
-## Why the client classifies empty as throttled
+1. **Allow our egress IP through the limiter.** In `limiter.toml`:
 
-A default engine set under load answers HTTP 200 with `results: []` (sometimes
+   ```toml
-with empty `unresponsive_engines`). That is indistinguishable from "nothing
+   [botdetection.ip_lists]
-found" unless the client refuses to call it absence.
+   pass_ip = ["77.7.46.234"]
+   ```
 
-## Instance-side levers
+2. **Shorten the suspensions.** In `settings.yml` the defaults are 24 hours for
+   a CAPTCHA and one hour for too-many-requests, which is far longer than the
+   condition lasts:
 
-1. **Allow the callers through the limiter** (`limiter.toml` `pass_ip`). The
+   ```yaml
-   Compose file uses RFC1918 only.
+   search:
-2. **Shorten suspensions** (`settings.yml` `search.suspended_times`) so a
+     suspended_times:
-   CAPTCHA does not last a day.
+       SearxEngineCaptcha: 300
-3. **More than one engine in `general`.** One live engine is a single point of
+       SearxEngineTooManyRequests: 120
-   failure. This repo enables bing, google, duckduckgo, wikipedia.
+       SearxEngineAccessDenied: 300
-4. **Keep the JSON API on.** `formats: [html, json]` must stay.
+   ```
+
+3. **Give `general` more than one working engine.** `google` and `wikipedia`
+   report `enabled: true` in `/config` yet never appear in a `general` response,
+   so they are not in the default set. Put them in it; one live engine per
+   category is a single point of failure.
+
+4. **Keep the JSON API on.** `formats: [html, json]` must stay, otherwise every
