The open review threads on this branch were all grounded in real issues:
a committed API key in handover docs, Unix-only locking and timeout
mechanisms, synchronous network I/O inside an async API path, and missing
retry/session reuse on market-data calls. This change removes the leaked
credential from the tracked docs, makes the portfolio and profiling paths
portable across platforms, moves live price fetches off the event loop,
and reuses the existing yfinance retry/session helpers where the review
called for them.
While verifying these fixes, the branch also failed to import parts of the
TradingAgents graph because two utility modules referenced by the new code
were absent. I restored those utilities with minimal implementations so the
relevant regression tests and import graph work again in this PR.
Constraint: No new dependencies; portability fixes had to stay in the standard library
Rejected: Add portalocker or filelock | unnecessary new dependency for a small compatibility gap
Rejected: Keep signal.alarm and fcntl as Unix-only behavior | leaves the reported review blockers unresolved
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep shared runtime paths cross-platform and keep async handlers free of direct blocking network I/O
Tested: python -m pytest -q web_dashboard/backend/tests/test_portfolio_api.py orchestrator/tests/test_quant_runner.py orchestrator/tests/test_profile_stage_chain.py tradingagents/tests/test_stockstats_utils.py
Tested: python -m pytest -q orchestrator/tests/test_trading_graph_config.py tradingagents/tests/test_research_guard.py
Not-tested: Full repository test suite and GitHub-side post-push checks
This change set introduces a versioned result contract, shared config schema/loading, provider/data adapter seams, and a no-strategy application-service skeleton so the current research graph, orchestrator layer, and dashboard backend stop drifting further apart. It also keeps the earlier MiniMax compatibility and compact-prompt work aligned with the new contract shape and extends regression coverage so degradation, fallback, and service migration remain testable during the next phases.
Constraint: Must preserve existing FastAPI entrypoints and fallback behavior while introducing an application-service seam
Constraint: Must not turn application service into a new strategy or learning layer
Rejected: Full backend rewrite to service-only execution now | too risky before contract and fallback paths stabilize
Rejected: Leave provider/data/config logic distributed across scripts and endpoints | continues boundary drift and weakens verification
Confidence: high
Scope-risk: broad
Directive: Keep future application-service changes orchestration-only; move any scoring, signal fusion, or learning logic to orchestrator or tradingagents instead
Tested: python -m compileall orchestrator tradingagents web_dashboard/backend
Tested: python -m pytest orchestrator/tests/test_signals.py orchestrator/tests/test_llm_runner.py orchestrator/tests/test_quant_runner.py orchestrator/tests/test_contract_v1alpha1.py orchestrator/tests/test_application_service.py orchestrator/tests/test_provider_adapter.py web_dashboard/backend/tests/test_main_api.py web_dashboard/backend/tests/test_portfolio_api.py web_dashboard/backend/tests/test_api_smoke.py web_dashboard/backend/tests/test_services_migration.py -q
Not-tested: live MiniMax/provider execution against external services
Not-tested: full dashboard/manual websocket flow against a running frontend
Not-tested: omx team runtime end-to-end in the primary workspace
Add _clean_dataframe() to normalize stock DataFrames before stockstats:
coerce invalid dates/prices, drop rows missing Close, fill price gaps.
Also add on_bad_lines="skip" to all cached CSV reads.
