Follow-up to the #1773 data-layer MVP (Taiwan suffix-only detection + routing,
merged in 2086e3c). That MVP deferred the service/API/frontend layers, leaving a
live defect: tw was absent from the DecisionSignal/Portfolio service VALID_MARKETS,
so _normalize_market("tw") raised ValueError on the decision-signal write path.
The analysis pipeline auto-extracts a DecisionSignal after history save
(_extract_decision_signal_after_history_save), so every tw analysis silently
failed to persist a signal while jp/kr succeeded -- tw was the only
yfinance-supported market that could be analyzed but never produced a signal.
Converge the tw market contract for DecisionSignal + Portfolio + Intelligence in
one pass (mirroring jp/kr #1720), per the human review on #1801 asking not to
land it piecemeal:
Backend service + API:
- src/services/{portfolio,intelligence}_service.py: VALID_MARKETS /
_ALLOWED_MARKETS + _normalize_market error strings accept tw
- src/services/decision_signal_service.py: _normalize_market error string
(VALID_MARKETS is imported from portfolio_service, so the set change propagates)
- src/services/decision_signal_extractor.py: drop the now-stale "(e.g. tw)" guard
comment (tw is supported; the guard still protects genuinely-unsupported markets)
- api/v1/schemas/{decision_signals,intelligence,portfolio}.py: Pydantic Literals + tw
- api/v1/endpoints/decision_signals.py + docs/architecture/api_spec.json: market
filter description + DecisionSignalMarket enum gain tw; test_api_schema_pydantic
exact-match vs create_app().openapi() passes (api_spec kept CRLF)
Frontend (DecisionSignal + Portfolio typed consumers only; tsc + vitest pass):
- apps/dsa-web/src/types/{decisionSignals,portfolio}.ts + pages/{DecisionSignalsPage,
PortfolioPage}.tsx + utils/{decisionSignalLabels,stockCode}.ts + i18n/uiText.ts:
add tw to the DecisionSignalMarket / portfolio market unions, the market filter
options, the tw display label, and .TW/.TWO stock-code normalization
- the alert Market-Light surface (types/alerts.ts MarketRegion, featureText
ALERT_MARKET_REGION_*) is intentionally LEFT OUT: the backend market_light_service
is cn/hk/us only, so exposing tw there would be a front/back mismatch
Tests:
- flip the two #1773 graceful-skip regressions to first-class assertions and add
test_extract_and_persist_writes_tw_signal (end-to-end persist guard)
- frontend: PortfolioPage + stockCode vitest gain tw cases
Docs (reconcile the tw contract so changelog/topic docs/code state one fact):
- docs/CHANGELOG.md: rewrite the #1772 [Unreleased] entries so they no longer say
"service/API deferred" + "tw gracefully skipped" alongside "tw now supported"
- docs/market-support.md, docs/decision-signals.md, docs/intelligence-sources.md:
sync the tw market enum / filter / examples; keep the boundary note
Still deferred (separate follow-ups): the Taiwan stock-index/seed + Web autocomplete,
and the alert (大盘红绿灯) Market-Light tw support (needs a market_light backend change).
