R3 slice 1 (research-deepening): persist a 4-field TrendScore {mode, dimensions,
composite, priority} on the store record (schema v2->v3, additive lossless), computed
by the already-built score.ts (composite+band, one owner), threaded item->store, and
rank rankForBrief on composite first + surface band+mode in renderBrief.
Go-gate confirmed (operator "Go"): D1 4-field envelope · D2 composite primary within
bucket · D3 first-sight only · D4 one slice · D6 mode shown per body entry.
Light-Voyage: scope-guardian ALIGNED (0) / brief-reviewer PROCEED_WITH_RISKS (6 MINOR)
/ plan-critic REVISE (1 BLOCKER, 4 MAJOR, 4 MINOR) — all folded. Headline fold: the RED
proof is now explicitly two-phase (logic-RED for store/brief/cli; stub-first then
assertion-RED for score/item, since a missing named import throws at module-load under
Node16 ESM, not on assertion).
