The visible layer of R2. Pure brief.ts: rankForBrief (pillar-overlap -> recency over the store; publishedAt ?? capturedAt freshness, 7d window; total-order sort), renderBrief (dated Markdown + hook-surfaceable summary frontmatter), briefSummary (one summary source), defaultBriefDir (derived from defaultStorePath). CLI `brief` writes <data>/trends/morning-brief/YYYY-MM-DD.md; session-start surfaces the latest zero-tsx (latestMorningBrief). Wired into trend-spotter Step 4.6 (scan->capture->brief->surfaced). No store-schema/scoring change; no scheduler (R3). 25 new trends tests (21 brief.test + 4 cli brief, RED-first) + 3 hook tests (morning-brief surfacing). trends 104/104 (floor 104), hook-suite 139/139, gate FAIL=0 (ASSERT floor 94, Section 16i: cli brief-handler + trend-spotter brief-pointer + session-start surfacing greps), tsc clean.
