City decision cards already had enough evidence, but the first screen still forced users to read the longer explanation before seeing why a card mattered. The header now caps status chips at three high-priority signals and uses product-facing labels for observed breakouts, stale METARs, AI loading, missing market prices, strong model agreement, and next-report waits.
Constraint: The card should stay lightweight and avoid another explanatory section.
Rejected: Keep six mixed freshness chips in the header | too much noise for first-glance scanning.
Confidence: high
Scope-risk: narrow
Reversibility: clean
Tested: npm run build
Not-tested: Browser visual QA across all city states.
The decision card now exposes deterministic guard state, data freshness, AI readiness and market sync directly in the card header so users can understand whether they are looking at fresh evidence, a fallback, or a stale/exception case before reading the full explanation.
Constraint: Keep the first useful read available while DeepSeek airport/HKO details are still streaming.\nRejected: Add another expanded evidence panel | header-level badges are faster to scan and avoid increasing card depth.\nConfidence: high\nScope-risk: narrow\nReversibility: clean\nTested: npm run build\nNot-tested: Browser visual QA on production data.
