Development summary

v1.8 — Quality, Reach & Decisions shipped.

All ten proposed candidates were approved and shipped in one wave on June 11, 2026: deeper signal quality (prosody, glossary, claim guard), a semantic layer over the catalogue (Atlas search), more reach from every video (quote cards, best-time, prompt A/B, Shorts Direct), and stronger decision support (Helm Briefing, client report links). Every card was tracked through the Threlmark board with started/done reports.

What shipped

Quality & intelligence

Prosody: real energy + emphasis per window (pure TS, no new Python).
Brand glossary fixes Whisper mishearings everywhere downstream.
Claim guard: per-claim fact-check verdicts + Studio warning badge.
Atlas v2: local embeddings → "Ask your catalogue" semantic search.

Reach & publishing

Quote cards: strongest lines as branded 1080×1080 images.
Best-time-to-post: learned posting windows pre-fill the schedulers.
Prompt-version A/B: prompts compete on real view signals.
YouTube Direct Shorts: per-clip upload via the brand's own OAuth.

Business & decisions

Helm Briefing: deterministic weekly digest per brand at /briefing.
Client report links: expiring read-only performance page per brand.
Costs and budgets stay operator-only — never in client reports.

Data model

Migration 0028_v18_wave.sql: brands.glossary, atlas_embeddings (emb_), briefings (brf_). Migration 0029_prompt_experiments.sql: nullable experiments.package_id/video_id + new asset_type. New job kinds: quote_cards, weekly_briefing.

Operational rules preserved

Prosody and embedding syncs are best-effort and never fail their producing workers. The glossary rewrites transcript text only — timings are immutable. Prompt-A/B winners are reported, never auto-applied. Shorts Direct falls back to Zernio rather than failing silently. Client reports never read the Helm Ledger.
