docs: delete agent-cost; rename kb-search skill to brain (#14)

* 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.

 `--hop` is not implemented (needs File/FROM_FILE edges); the flag errors instead of walking. `bin/kb/search` is a deprecated wrapper around `bin/brain/search.go`.
 
-Git history is read with [go-git](https://github.com/go-git/go-git) (no git binary):
-
-```bash
-bin/git/import.go --json --limit 100              # commit leafs for this repo
-bin/git/import.go --root "$PROJECTS_ROOT" --json  # one pass per .git under root

-
-Conversion only. Graph write (`File-[:HAS_VERSION]->Commit-[:AUTHORED]->Person`) stays with `bin/brain/index.go`.

-Web search (second independent source) goes through SearXNG. Empty results mean **throttled**, not “nothing exists”:

-# 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

-## Optional Compose profile
+## Why it is needed
 
-Do not start this on a host that already runs SearXNG — set `BRAIN_SEARCH_URL`
+Measured on 2026-08-10 from this host:
-instead (D3).
 
-```bash
+- The default engine set for the `general` category is only `duckduckgo`,
-SEARXNG_SECRET=$(openssl rand -hex 32) docker compose --profile searxng up -d
+  `brave` and `startpage`. `brave` and `startpage` sit in
-```
+  `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
+   client here breaks.
 
 ## Verifying
 
+Ten requests in a row used to suspend the instance for minutes. After the
+change they should all answer:
+
 ```bash
 for i in $(seq 10); do
-  bin/web/search.go "test $i" -n 1 --refresh --json | jq -r .status
+  bin/web/search "test $i" -n 1 --refresh --json | jq -r .status
 done
 ```
 
-Ten lines of `ok` means the instance is healthy. Any `throttled` means say
+Ten lines of `ok` means it is fixed.
-nothing about whether the subject exists.
