Repair FastAPI Deferred Job Dependency Lifetime

Repair FastAPI Deferred Job Dependency Lifetime — SYNTHETIC EVIDENCE-LIMITED REVIEW

Case received

A web task fails only after the original HTTP request completes.

Evidence register

• S1: FastAPI background task lifecycle traces and dependency scope logs — PARTIAL / UNVERIFIED.
• S2: approved operating baseline / documented policy — NOT PROVIDED; REQUIRED TO VERIFY.
• S3: timestamped revision or change record — NOT PROVIDED; REQUIRED TO VERIFY.
• S4: accountable reviewer and approval evidence — NOT PROVIDED; REQUIRED TO VERIFY.

Investigation checks

1. Establish the identity, timestamp basis and revision lineage of FastAPI background task lifecycle traces and dependency scope logs; document missing or contradictory records. — PENDING CORROBORATION.
2. Reconstruct the event sequence surrounding task accesses disposed request-scoped dependency during later execution, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
3. Compare the evidence with the approved baseline; test the competing explanations for: A web task fails only after the original HTTP request completes. — PENDING CORROBORATION.
4. Draft a non-executing, owner-approved validation sequence and rejection criteria for task lifetime and dependency isolation regression cases. — PENDING CORROBORATION.

Deliverables

• exceptions and alternative hypotheses for task accesses disposed request-scoped dependency during later execution: DRAFT / INCOMPLETE until inputs are validated.
• approval-gated task lifetime and dependency isolation regression cases and verification criteria: DRAFT / INCOMPLETE until inputs are validated.
