Write Weekly Digest

Workflow

Compose digest:
- [ ] Step 1: Load ranked keep list + drop list
- [ ] Step 2: Fill frontmatter
- [ ] Step 3: Render top-signals section (≤10 items)
- [ ] Step 4: Render explicit-drops section
- [ ] Step 5: Render appendix (every source surveyed + freshness state)
- [ ] Step 6: Voice-profile lint: no banned vocabulary; one-sentence paragraphs at pivots
- [ ] Step 7: Write ops/trend-scout/YYYY-WW-digest.md

Output format

---
week: YYYY-WW
generated: ISO8601
items_surveyed: N
items_kept: K (≤10)
items_dropped: D (explicit, with reasons)

# Week {WW} Digest — YYYY-MM-DD through YYYY-MM-DD

## Top signals ({K})

### 1. {Source} — {Title}
- URL: {full URL}
- Why this matters: {1-line teaches-X summary}
- Dedup: NEW | OVERLAPS {status}:{slug}
- Seed candidate: YES: {angle} | NO: {reason}
- Reading time: {N} min

### 2. ...

## Explicit drops ({D})
- {URL}: {1-line reason}
- ...

## Appendix: all sources surveyed
- {source}: {fresh | stale | failed} + one-line note
- ...

Guardrails

1. Hard cap 10 keeps.
2. Never publish with 0 drops in a week where >5 items were fetched.
3. Appendix is mandatory — audit trail.
4. Voice-profile lint catches banned vocabulary before writing.
5. Idempotent: running twice in one week overwrites deterministically.
6. Every "Why this matters" is the summary from summarize-signal, not a rewrite.
