R3 slice (b): the rest of hull #3. The morning brief now reads the temporal axis
the R3b seen-log records but the ranking ignored. Two DERIVED signals, computed at
brief time from already-persisted fields (publishedAt/capturedAt -> ageDays,
surfacedCount), never stored:
- first-mover: recent (ageDays <= --first-mover-days, default 2) AND never surfaced
on a prior day -> ranked up, badge "first ute". Future-dated (ageDays<0) excluded.
- saturation: surfaced on >= --saturation-at (default 3) prior days -> ranked down,
badge "mettet (Nx)". Self-surfacing (our seen-log), not market coverage.
- warming (1..at-1) keeps the R3b "sett Nx" badge but only at >=2 (contract intact);
neutral carries no badge.
SB1 derived (no schema bump: SCHEMA_VERSION 4 / BRIEF_SCHEMA_VERSION 1 untouched).
SB2 the R3a relevance composite stays the PRIMARY sort key; the temporal rank is a
new cmp key after pillar-overlap, before effectiveDate -> re-orders only WITHIN a
(composite, overlap) tier. temporalSignal is pure (saturationAt clamped >=1).
Prior-day surfacings exclude today (via lastSurfacedAt), so a same-day re-render is
byte-identical (caught by the R3c run-daily SC7 regression; fixes a latent R3b
prior-day imprecision too). brief CLI gains --first-mover-days / --saturation-at;
schedule untouched (nightly uses defaults).
Wiring: trend-spotter.md (prose), trend-scoring-modes.md (one-line consumer note),
README (## Temporal overlay), gate Section 16m (+6 unconditional -> ASSERT floor
111->117), TRENDS_TESTS_FLOOR 192->216. Counts 29/19/27 unchanged. Zero new files.
Gate: Passed 132 / Failed 0; trends 216/216; hook suite 139/139 untouched.
