ScanTerminalDashboard had accumulated terminal fetching, theme persistence, local clock updates, and AI pinned-city hydration in one component. Moving those responsibilities into focused hooks keeps the screen component as the composition layer while preserving the existing UI and data flow.
Constraint: Refactor must not change the current decision-card or scan-terminal behavior.
Rejected: Split visual card components in the same commit | too much surface area for one safe refactor pass.
Confidence: high
Scope-risk: moderate
Reversibility: clean
Tested: npm run build
Not-tested: Browser manual regression across map, calendar, and pinned-card interactions.
Users needed reassurance that unavailable quotes and long AI evidence are normal states, not broken systems. This adds a v1.5.5 upgrade announcement, softens market-unavailable copy, surfaces a one-line recommendation reason, and makes mobile cards prioritize observed temperature, expected high, peak timing, AI expansion, and a separate market line.
Constraint: Keep existing dashboard data contracts and avoid backend schema changes.
Rejected: Hide unavailable market rows entirely | users still need to know weather evidence remains usable without a quote.
Confidence: high
Scope-risk: moderate
Reversibility: clean
Tested: npm run build
Not-tested: Browser visual QA on physical mobile devices.
Users need to know whether a city can be acted on before reading the full explanation. City cards now expose METAR or official-observation freshness, model update timing, market quote freshness, and AI state in a dedicated trust block, while the calendar view groups rows into action-oriented timing buckets with a single reason per city.
Constraint: Keep the existing card and calendar data contracts; derive freshness and action reasons from fields already present in the frontend payload.
Rejected: Add another long explanatory paragraph | it would repeat the same trust problem instead of making the first glance clearer.
Confidence: high
Scope-risk: moderate
Reversibility: clean
Tested: npm run build
Not-tested: Live browser visual QA with stale METAR and delayed quote examples.
Users saw fast-rule evidence, partial streams, DeepSeek completion, and fallback states as one blended AI status. The city evidence panel now names the current stage directly so a loading stream reads as fast judgment complete, a successful response reads as AI bulletin read complete, and incomplete responses explain that rule evidence is being used.
Constraint: Keep the existing fast evidence path visible while DeepSeek streams in.
Rejected: Label fallback as an AI failure | that incorrectly implies the card is broken even when rule evidence is valid.
Confidence: high
Scope-risk: narrow
Reversibility: clean
Tested: npm run build
Not-tested: Manual browser timing of partial stream transitions.
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.
Qingdao needs the same airport-settlement path as the other Wunderground-backed APAC cities, so the registry, aliases, timezone, prewarm, official links, market focus, and tests now point to ZSQD / Qingdao Jiaodong International Airport.
Constraint: User supplied Wunderground Qingdao/ZSQD settlement URL.
Rejected: Add a partial registry-only entry | it would show in APIs without frontend links, prewarm coverage, or alias support.
Confidence: high
Scope-risk: narrow
Reversibility: clean
Tested: pytest tests/test_country_networks.py tests/test_web_observability.py::test_cities_endpoint_includes_new_wunderground_cities -q
Tested: npm run build
Not-tested: Live Wunderground fetch for ZSQD in production.
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.
City-card fallback reads now stop using stale METAR or official observations as strong live anchors. A stale observation no longer forces high/low revisions, and both backend and browser AI cache keys include the observation fingerprint so updated report times, receipt times, temperatures, or stale status invalidate old AI text.
Constraint: Cached city AI reads must not survive a material observation update
Rejected: Let stale METAR trigger observed-break revisions | stale reports can be older than the active temperature path
Confidence: high
Scope-risk: moderate
Tested: pytest tests/test_web_observability.py -q
Tested: npm run build
The prior label said the weather decision layer had no market price connected, which could be read as a broken market integration. The card now says weather-first read with market prices shown separately.
Constraint: Market price layer is already rendered below the weather decision band
Rejected: Keep 'no market price input' | accurate internally but misleading in user-facing Chinese copy
Confidence: high
Scope-risk: narrow
Tested: npm run build
Not-tested: Visual screenshot review
City AI can return a partially streamed JSON string when the provider truncates output. The fallback previously kept an unfinished clause such as '但TAF显示', which made the forecast explanation look broken even though earlier evidence was usable.
Constraint: Provider JSON can be truncated after useful fields have already streamed
Rejected: Drop all partial AI text | would lose valid METAR interpretation already returned before truncation
Confidence: high
Scope-risk: narrow
Tested: pytest city AI truncation regression tests
Tested: npm run build
Not-tested: Live DeepSeek provider response
The calendar local-time and AI airport-read fixes are a numbered product release rather than a temporary snapshot, so the changelog and package/version metadata now use 1.5.5 consistently.
Constraint: Existing snapshot tag was already pushed before the numbered release correction
Rejected: Keep snapshot label in changelog | user clarified this should be the 1.5.5 version
Confidence: high
Scope-risk: narrow
Tested: Reviewed git diff for CHANGELOG, VERSION, frontend package metadata
Not-tested: No runtime tests; metadata-only version correction
