Deduction search over the 2dph brain (Ladybug graph: ops corpus, portfolio,
|
||
ssh hosts) with bin/brain/search.go instead of reading files or grepping
|
||
repos. Use whenever a question starts with "where is", "what runs on",
|
||
"which file describes", "who is", "how is X done", before opening any
|
||
documentation.

# brain — deduction over facts and info
|
||
|
||
One embedded Ladybug graph (`var/kb.lbug`, read-only when queried) holding two
|
||
roots:
|
||
|
||
- **facts** — assertions backed by ≥2 independent sources (docker ps × compose
|
||
× ssh-config × docs), `confidence: confirmed`.
|
||
- **info** — descriptive/narrative leafs, searchable, never asserted.
|
||
|
||
Search = deduction: facts root first, info root second, `web-search` as the
|
||
second independent source when local roots cannot confirm. An answer is
|
||
`confirmed` only if it comes off the facts root; anything else is
|
||
`(not confirmed)`.
|
||
|
||
```bash
|
||
bin/brain/search.go "Matrix federation" # pointers + snippets, YAML
|
||
bin/brain/search.go "onlyoffice postgres" --root facts # restrict to confirmed
|
||
bin/brain/search.go "where is cs-lexicon" --json | yq '.[].ref'
|
||
bin/brain/get.go <id> --body # full chunk only when needed
|
||
bin/brain/stats.go # index health
|
||
bin/brain/eval.go # recall@5 >= 0.95 gate
|
||
```
|
||
|
||
`bin/kb/search` is a deprecated wrapper. `--hop` errors (File/FROM_FILE edges
|
||
are not wired yet); do not treat it as a graph walk.
|
||
|
||
## Rules
|
||
|
||
- Search before you read. Never grep a repo for a concept the graph covers.
|
||
- `--root facts` returns only confirmed evidence-linked answers. Default shows
|
||
facts first, then info leafs clearly marked `(not confirmed)`.
|
||
- If recall looks wrong, run `bin/brain/eval.go`; it gates control questions and
|
||
should stay at or above 95% recall@5.
|
||
- Escalate to `web-search` (the `web-search` skill) as the independent second
|
||
source when both local roots cannot confirm; never report an unconfirmed
|
||
single-source local answer as fact. |
