The visible layer of R2 (R2a landed the data layer @ 7a15803). A pure
rankForBrief (pillar-overlap -> recency over the store, publishedAt ?? capturedAt
freshness, 7d window) + renderBrief (dated Markdown with a hook-surfaceable
summary frontmatter) + briefSummary (one summary source) + defaultBriefDir
(derived from defaultStorePath). CLI `brief` writes the dated file; session-start
surfaces the latest, zero-tsx. Wired into trend-spotter (scan->capture->brief->
surfaced). No store-schema change, no scoring change, no scheduler (R3).
Light-Voyage hardened: scope-guardian ALIGNED (0); brief-reviewer
PROCEED_WITH_RISKS; plan-critic REVISE (2 blockers, 5 majors, 4 minors) — all
folded (briefSummary single source, wrong-value RED stubs, --out !== "true"
guard, defaultBriefDir derives from defaultStorePath, two-gate split since the
hook suite is not in test-runner.sh, url-asc total order). Go-gate: WIRE +
English "## Morning Brief" heading.
