unsupported_report_snapshot

Error message

source report snapshot cannot produce a valid decision signal: {exc}

What it means

During persist, create_history_bound_signal_with_outcome can raise ValueError when the payload built from the source report is not valid (score/action/phase fields etc.); the reassess service wraps it as DecisionSignalUnsupportedReportSnapshotError (code=unsupported_report_snapshot), signaling the report snapshot's data cannot yield a well-formed decision signal.

Solutions

1. Inspect the report's raw_result/context_snapshot for the required fields (dashboard, action, sentiment_score, market_phase_summary).
2. Choose a recent report generated by the current engine; skip legacy snapshots.
3. If the report class is needed, fix/normalize its raw_result before reassessing.

Example fix

# before
outcome = service.reassess(source_report_id=legacy_id, decision_profile="balanced", persist=True)

# after
recent = next(r for r in db.list_analysis_history(limit=20) if r.raw_result.get("dashboard"))
outcome = service.reassess(source_report_id=recent.id, decision_profile="balanced", persist=True)

raw = _parse_mapping(getattr(record, "raw_result", None))
required = ("dashboard", "action")
missing = [k for k in required if k not in raw]
if missing:
    return JSONResponse(status_code=422, content={"error": "unsupported_report_snapshot", "missing": missing})
result = service.reassess(source_report_id=rid, decision_profile=profile, persist=True)

def isReassessableSnapshot(raw_result: dict) -> bool:
    return isinstance(raw_result, dict) and "dashboard" in raw_result and raw_result.get("action") is not None

from src.services.decision_signal_reassess_service import DecisionSignalUnsupportedReportSnapshotError

try:
    outcome = service.reassess(source_report_id=rid, decision_profile=profile, persist=True)
except DecisionSignalUnsupportedReportSnapshotError as exc:
    return JSONResponse(status_code=422, content={"error": "unsupported_report_snapshot", "message": str(exc)})

When it happens

Trigger: POST reassess persist=true on a legacy report whose raw_result lacks required keys (dashboard/action/score) or carries values the downstream validation rejects (None score, unknown action, malformed market_phase_summary).

Common situations: Old reports written before schema changes; partial/failed analyses saved with raw_result present but incomplete; reports generated by a different engine version.
