2 things to look at
- 12 days oldThe repository was created 12 days ago. New is not bad, but a brand new repository carrying a familiar-sounding name is the shape a typosquat arrives in, and there has been no time for anyone else to find a problem with it.
- 0 stars0 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

Core draft artifacts
Every draft / improve emits: article, claim ledger, adversarial Q-test,
residual risks, CLEAR scorecard. Templates: references/artifacts.md.
Draft pipeline (summary)
- Lock JTBD · 2. Intent purity · 3. Evidence plan · 4. Spine Picker + journey map · 5. Write extractable answers · 6. Stress tests · 7. Deliver or block.
Full craft: references/craft.md · forms: references/forms.md · evidence: references/evidence.md.
Stress tests (blocking)
| # | Test | Pass |
|---|---|---|
| 1 | Claim ledger | No blocked material rows |
| 2 | Contradiction hunt | No internal conflicts |
| 3 | Q-test | 5/5 extractable |
| 4 | CLEAR | ≥ 85 |
| 5 | YMYL | Intensifier green if triggered |
| 6 | Accessibility | Alt, links, heading order |
Extended modes (quick contracts)
Horizon Brief (horizon)
90-day plan: ICP jobs, surface bets, hub/spoke candidates, evidence gaps, KPI per asset. Hand production to draft / graph-run.
Spine Picker (spine)
Pick form from references/forms.md using JTBD + competitor spine gaps. Output: chosen form + rejected forms + why.
Ship Scan (ship-scan)
Owned SEO + extractability checklist (titles, meta, headings, links, OG, schema mirror, extractable opens). See references/ship-scan.md. Separate from CLEAR.
Job Collision Map (collision)
Given a corpus (paths or titles+jobs), flag overlapping JTBDs. Recommend merge, differentiate, or prune.
Cite Surface Audit (cite-surface)
Full citation readiness beyond cite-probe: entity stability, passage inventory, crawler access notes, structure for extraction. references/cite-surface.md.
Claim Probe+ (verify)
Per claim: support status, confidence (high/med/low), echo risk (same claim repeated without new evidence), fix action.
Freshness Drift (freshness)
From traffic/export deltas or stale dates: classify refresh / consolidate / prune; attach update triggers. references/freshness.md.
Graph Runner (graph-run)
Cluster plan → ordered spoke briefs → ship sequence with dependencies. Reject duplicate jobs.
Mirror Markup (mirror)
Emit JSON-LD only mirroring visible content (BlogPosting/Article, Person/Organization, BreadcrumbList). No invisible FAQ games.
Locale Lattice (locale)
Plan locales, adaptation depth (translate vs cultural), hreflang pairs, parity checklist. references/locale-lattice.md.
Frame & Tone Kit (frame)
Tool-agnostic briefs: hero brief, chart-from-ledger, optional TTS narration brief. references/frame-tone.md.
Signal Bridge (signal-bridge)
Checklist for plugging CWV, Search Console, analytics, keyword exports — no vendor lock-in. references/signal-bridge.md.
Release Latch (release)
Pre-handoff: required artifacts present, links resolve policy, hero/social image notes, review.md summary. references/release-latch.md.
YMYL
See references/ymyl.md.
