feat: escalate brain search to web when facts cannot confirm

* docs: delete agent-cost; rename kb-search skill to brain.

bin/agents/cost does not exist. CI unittest now fails if a SKILL.md names a
missing bin/ path.

* test: gate SKILL.md bin/ paths; name the brain skill brain.

Follow-up to the agent-cost delete: unittest fails if a skill names a missing
tool. Frontmatter name is brain, not kb-search.

-| Order | Issue | Gap |
-|-------|-------|-----|
-| 1 | [#14](https://git.produktor.io/eSlider/2dph/issues/14) | **in** — `bin/brain/add.go` / `POST /ingest` write facts+info without deleting `kb.lbug`. Bulk corpus still `--rebuild`. Leftover Python (mail/facts) is not the living-graph blocker. |
-| 2 | [#17](https://git.produktor.io/eSlider/2dph/issues/17) | `--hop` errors. `FROM_FILE` / `HAS_VERSION` are in schema; search does not walk them. |
-| 3 | [#18](https://git.produktor.io/eSlider/2dph/issues/18) | Rebuild is mostly `info` (repo md + mail). `facts/extract` and chats are not a first-class index input. WhatsApp sync is a stub. |
-| 4 | [#15](https://git.produktor.io/eSlider/2dph/issues/15) | **in** — lever/loop documented (`search` → `get` → `audit`). |
-| 5 | [#19](https://git.produktor.io/eSlider/2dph/issues/19) | GitHub CI recall still runs Python `bin/kb/eval`. |

-Does **not** block epic close: [#6](https://git.produktor.io/eSlider/2dph/issues/6) OCR, OQ1, OQ3, OQ4.

+# 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

-Both loaded models emitted OpenAI `tool_calls` (not `<tool_call>` XML) on

-(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 `bin/brain/add.go` for a leaf (or `POST /ingest`). Bulk
-corpus rebuild remains `bin/brain/index.go --rebuild` (Compose profile
-`index`). Do not DROP INDEX on Ladybug 0.19.
-
-```bash
-bin/brain/add.go --text "arc-1 runs Matrix" --root facts --source "compose.yml x docker ps"
-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
-```
