B44 · App pages — Numbers UI #55

Checklist item: B44-e — scope + DoD per workspace CHECKLIST.md (source of truth; never enters the repo)
Milestone: Phase 5 — UI
Blocked by: #45 (B47)

The Big Idea

Numbers page rendering B23's modelled chain data with honest estimates labelling.

Details

The storage/cost numbers section fed by B23's single model. MODELLED ESTIMATES labelling everywhere these values render (NUM-1/NUM-2); empty/degraded states when cron data is stale.

Recommend tests

• Values identical to Config wizard panel (one-model check).
• Stale-data degraded state demonstrated.
• Estimates labelling present.

Potential code references, but use your judgement

• None yet — greenfield within the new docs/ tree; add references as the area takes shape.

Definition of Done

• Formatted (prettier / fourmolu)
• Static analysis clean (tsc --noEmit · eslint · hlint), no new warnings
• Unit tested; coverage does not regress
• Cited criteria verified — by test or recorded measurement, not inspection
• CI green end to end
• No previously-satisfied criterion broken; generated artifacts still regenerate byte-identical
• Part of B44 — closes with it
