A straddling concept resolves by one rule: cohesive logic gets an owner and an interface; a mere sequence dissolves

Context

The 9-module refactor repeatedly hit concepts that live across two or more modules — grounding-floor (Aquisição↔Julgamento), Assemble (Plataforma↔Aquisição↔Cortex), wiki_render (Provisão↔Cortex), the Voz rail (Publicação↔Curadoria↔Aquisição), Conductor (Produção↔Julgamento), Rich-rite/Depth (Produção↔Julgamento), and eventlog's query surface (Plataforma↔Cortex). Each is a decision about where the logic lives, and left ad-hoc they re-create the leaks the refactor is meant to remove.

Decision

A straddling concept is resolved by one test: does it have cohesive logic of its own?

• Yes → one owner module + a narrow interface. The other modules call the interface; they never

re-implement it. (e.g. grounding-floor is owned by Aquisição; Julgamento calls grounding.floor().)

• **No — it is only a sequence of other modules' acts → it dissolves.** The logic returns to the

modules it spanned; a thin sequencer coordinates. (e.g. Assemble — see ADR-0020.)

Consequences

• No module contains another module's logic; every straddle becomes owner+interface or dissolution.
• This is the standing test for every future straddle, not a one-off resolution.
• First application on record: ADR-0008 (Consolidate dissolved). The seam-owner assignments and the

9-module map live in CONTEXT.md.
