determine-signals

Find out what has already been said — in transcripts, issues and PRs, the ledger, the notebook, and vault facts — before asking a question or stating a fact as current, and prefer live system state over any stored record when they disagree. Use before acting on a non-trivial request, right where you would otherwise ask something you could answer by looking, or restate a fact without rechecking it. Not for what the user wants (see determine-intent, which runs on the same "before acting" moment but asks the goal, not the record); not a deliberate periodic transcript sweep for new skill candidates (see mine-transcripts, which is scheduled, not per-task); not for judging whether a check or metric can be trusted once you have its verdict (see verify-the-instrument) — this skill decides which signal source to consult and which one wins when two disagree, not whether a given source's zero result is real.
