- Add comprehensive docstring to runtime_state.py explaining single-process
constraint, impacts in multi-worker deployments, and solution approach
- Add comprehensive docstring to session_cache.py explaining process-local
cache limitation, security implications, and Redis/database alternatives
- Update Architecture.md to clarify session cache is process-local and
describe single-worker enforcement via TASK-002
- Update Architecture.md runtime state section with detailed explanation of
per-process state and multi-worker impacts
- Add Backend-Development.md section 13.7.2 documenting session cache
pluggability pattern with example Redis implementation
- All tests pass; linting passes; type checking has pre-existing errors
This is the short-term fix for TASK-003: enforce single-worker deployment
(TASK-002) and document the constraint clearly. The long-term fix (Redis
backend) is deferred as a follow-up.
