Clarify a specification

Input: request, source documents, current explicit decisions and caller's source-precedence policy. Return established requirements with sources, out of scope, resolved contradictions and open decisions. Do not invent a universal document hierarchy if none is supplied.

1. For each requested behavior, identify actors, inputs, states, outputs and failure conditions needed to implement it. Read relevant repository conventions and supplied references; mark inaccessible sources.
2. Separate a contradiction from a detail omitted by a higher-level source. Apply the caller's precedence policy; preserve an explicit later decision and record the arbitration. Escalate a conflict whose intended authority remains unclear.
3. Distinguish an established requirement, a sourced technical inference and an unresolved product choice. Existing conventions can settle an implementation detail, but cannot create permission rules, limits, endpoints or user-facing copy absent from the request.
4. Ask only questions whose alternatives materially change the result, through the caller's interaction channel, and only once the sources, the repository and the linked work give no answer. An implementation, testing or measurement choice is a sourced technical inference to settle and record, never a question; a proposal the ticket makes while awaiting confirmation is implemented as proposed and flagged. Give concrete options and their consequences. Reuse answers already supplied. A question about what the system does today is a fact, not a decision: answer it yourself when it can be read or run without starting the application (an existing test, a script, a reachable endpoint). When only the running application can show it, ask, and mark the question observable with the measurement that will check the answer.
5. Propose testable acceptance wording without silently changing meaning. When a registry is supplied, preserve its ids and revision; propose additions as questions for its owner.

Stop with useful partial findings when sources are missing. Return questions to the caller rather than blocking unrelated work or answering on the user's behalf.
