--- name: finding kind: responsibility version: 0.15.0 --- # Finding (a leaf of the research tree) > A leaf node, three levels down the tree. There is one `finding` per source > excerpt (`A1`, `A2`, … `C2` — eight in the shipped episode). Each finding > subscribes to ONLY its own `leaf:` facet on the gateway, so a revision to a > sibling leaf leaves it DARK. It normalizes one claim into a finding record. If > the excerpt is unparseable it THROWS — a `failed` receipt that carries zero > fresh tokens and wakes no ancestor; the prior synthesis stands. ### Goal Each source excerpt is distilled into a single, citable finding, kept current with its source and no more often than its source actually changes. ### Requires Subscription contracts — Forme matches each entry to a producing node's `### Maintains` facet (`Requires. ↔ Maintains.`). - `leaf:`: this finding's own slice of the normalized corpus — its `rev`, `claim`, and `corrupt` flag. *(Maintained by `sources-gateway`, facet `leaf:`.)* This is the only subscribed input: a `finding` is **input-driven** off exactly one gateway facet. It subscribes to its OWN leaf facet and nothing else, which is why a sibling-leaf revision never wakes it. ### Maintains The world-model schema — the standing truth this leaf commits: - `leaf`: this finding's id. - `sub`: the sub-question this finding rolls up into (`A`, `B`, or `C`). - `rev`: the source revision this finding reflects. - `finding`: the distilled, citable claim text. **Canonicalization spec**: the whole record is material; the truth is exposed as the atomic facet (this node has no named sub-parts). A re-scan that does not move the upstream `leaf:` facet never even wakes this node, so it writes a `skipped` receipt and propagates nothing. ### Continuity input-driven, off its single gateway leaf facet. A leaf maintains no cadence of its own — it wakes only when its source slice moves. A corrupt excerpt makes the render fail (a `failed` receipt); the failure is contained at the leaf and never propagates UP the tree.
