# Context Answer

`POST /context/answer`

## Request

- Base URL: `https://mcp.physea.ai` (the document declares no server; this is the origin it was published from)
- URL: `https://mcp.physea.ai/context/answer`

Answer one leaf for THIS caller (server-side identity, IDOR-safe like /context/preference).
Body {leaf, value, leaf_text?, branch_id?, source_ref?}. `leaf` may be the leaf text or the
leaf key; a key needs `leaf_text` unless a fact with that key already exists (we reuse its
text). Returns {ok, caller, leaf_key, fact, branched, other_branches}. 400 E_BAD_REQUEST
when the leaf text cannot be established.
