Run the Alembic guardrail before the documented upgrade.
The runbook instructs operators to run flask db upgrade without first running the required guardrail. Add make alembic-guardrail or python scripts/check_alembic_revision_guardrail.py before the upgrade command.
As per coding guidelines: “Before deployment or running flask db upgrade, run make alembic-guardrail or python scripts/check_alembic_revision_guardrail.py.”

Do not describe concurrent consumption as safe without a claim step.
Two consumers can both execute the query at Lines 94-98 before either writes consumed_at. Both consumers can then map the same rows. The later UPDATE does not prevent duplicate mapping.
Make row claiming mandatory. Use an atomic claim token or processing state, or hold FOR UPDATE SKIP LOCKED through the mapping transaction. Document recovery for abandoned claims.

| ## UNCERTAIN row policy | ||
|
|
||
| - B writes `llm_label = 'UNCERTAIN'` when the LLM returned UNCERTAIN, or when the response failed to parse / the batch failed (confidence 0.0). | ||
| - **Recommended C behavior:** filter to `KNOWLEDGE` for normal mapping; UNCERTAIN rows are for Module D's HITL review. | ||
| - **If Module D isn't live yet:** C MAY treat UNCERTAIN as KNOWLEDGE (slightly higher false-positive rate); document the choice. |

Remove the unsupported UNCERTAIN fallback or mark it as future behavior.
The contract states that Module C filters to llm_label = 'KNOWLEDGE', but this section also permits C to treat UNCERTAIN as KNOWLEDGE. That option does not match the shipped consumer and can send unreviewed rows into mapping. Keep UNCERTAIN for Module D, or define a new versioned C behavior before documenting this fallback.
Based on learnings: “In OWASP/OpenCRE Module C, DbKnowledgeSource._query() filters live knowledge_queue rows by llm_label == "KNOWLEDGE" before the C.0 boundary. Therefore, Module C never reads or retires UNCERTAIN rows; they remain for Module D, and an accumulating UNCERTAIN tail is expected until Module D exists.”
