Phase 3 adds concrete data-quality states to the contract surface so weekend runs, stale market data, partial payloads, and provider/config mismatches stop collapsing into generic success or failure. The backend now carries those diagnostics from quant/llm runners through the legacy executor contract, while the frontend reads decision/confidence fields from result or compat instead of assuming legacy top-level payloads.
Constraint: existing recommendation/task files and current dashboard routes must remain readable during migration
Rejected: infer data quality only in the service layer | loses source-specific evidence and violates the executor/orchestrator boundary
Rejected: leave frontend on top-level decision fields | breaks as soon as contract-first payloads become the default
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: keep new data-quality states explicit in contract metadata and route all UI reads through result/compat helpers

Tested: python -m compileall orchestrator tradingagents web_dashboard/backend
Tested: npm run build (web_dashboard/frontend)
Not-tested: real exchange holiday calendars beyond weekend detection
Not-tested: real provider-backed end-to-end runs for provider_mismatch and stale-data scenarios
Phase 1 left the backend halfway between legacy task payloads and the new executor boundary. This commit finishes the review-fix pass so missing protocol markers fail closed, timed-out subprocesses are killed, and successful analysis runs persist a result contract before task state is marked complete.
Constraint: env312 lacks pytest-asyncio so async executor tests must run without extra plugins
Rejected: Keep missing marker fallback as HOLD | masks protocol regressions as neutral signals
Rejected: Leave service success assembly in AnalysisService | breaks contract-first persistence and result_ref wiring
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Keep backend success state driven by persisted result contracts; do not reintroduce raw stdout parsing in services
