Pipeline

Load anchors

SP loaded as system message (voice anchor, Rule 4). Task prompts: SP · COS.youtube_brief. Pull ≥3 reference IDs (Rule 2). Reads locked upstream: 15.

Generate

Per COS schema (Hook + Value + Payoff + Next Steps)

QA gate

Section 25 auto-runs QA L1 (24 checkpoints) + L2 (6 brand gates). Any L2 fail = REJECT → rewrite.

Render + ship

Sync to brand.assets. POC approves in portal → /api/brand-os/approve writes the asset → ships to domain.

SCHEMA NOTE: verify all jsonb paths + brand.assets type values against live Supabase before write. Flag missing columns in the PR; never create new columns without review.

Note

This is a HIFI artifact: its consumer is a real customer. It only renders content that already passed the LOFI gate upstream — it never invents facts. Source of truth: Master Template Part 3 + the Master Index. To change this page, edit content/docs/roadmap/_sections.json and re-run the compiler.
