Persimmon

Use this when an agent needs Persimmon's deterministic momentum score for a specific brand or the top of the index. Returns composite score plus four dimensions (Draw, Surge, Wedge, Hold), tier band, signal count, and last-updated timestamp. Pure read; no LLM calls in scoring.

Use this when an agent needs the recent harvested signals (each with text, tier, score, and source URL) backing a brand's score. Public-citable signals only — internal-only items are filtered before emit. Always carries a coverage_status describing why a list may be empty.

Use this when an agent needs a brand's competitor set, peer momentum snapshots, and a deterministic competitive-position one-liner. Excludes peers without real signal coverage (scaffold tier). Always carries a coverage_status describing the result.
