The city decision fallback path is generated when the full DeepSeek city-airport read has not completed, so the reasoning copy now labels the state as fast evidence mode instead of saying the AI read is normal.
Constraint: Fallback output may use only DEB, model cluster, and latest observation evidence
Rejected: Keep 'AI read normal' wording | it implies a completed AI interpretation when the fallback path is active
Confidence: high
Scope-risk: narrow
Tested: pytest tests/test_web_observability.py::test_city_ai_fallback_reasoning_identifies_fast_evidence_mode tests/test_web_observability.py::test_city_ai_partial_json_trims_dangling_taf_clause tests/test_web_observability.py::test_city_ai_schema_completion_trims_dangling_taf_clause -q
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
The release snapshot is no longer unreleased, so the changelog now names the published calendar-local-time tag and records the AI wording and actionable-window behavior.
Constraint: Existing snapshot tag was already pushed before this documentation correction
Confidence: high
Scope-risk: narrow
Tested: Documentation-only change reviewed with git diff
Not-tested: No runtime tests; changelog-only update
