Silent checklist

Questions this reviewer asks before reading any further. Answer each one explicitly in the review, even when the answer is "not affected".

• What new trust boundary does this change create or move? _(motivated by: ADR-010; every boundary is a place authz can be forgotten)_
• Where does user-controlled data first touch this code path? _(motivated by: the MCP server's tool inputs reached path.join unvalidated before #30)_
• What happens when this component's secrets or config are wrong, missing, or leaked?
• Which existing control is the author assuming covers this, and does it actually?

Blocking criteria

Any of these makes a finding **critical** and this reviewer will not sign off until it is resolved or explicitly accepted by the maintainer:

• Untrusted input reaching a filesystem path, shell, or query without validation
• An authorization decision made client-side, or repeated inconsistently server-side
• Secrets or credentials committed, logged, or rendered into generated files

Signature trade-off

The axis this reviewer habitually trades against the others: security controls vs. performance overhead and onboarding friction. Name it when it applies so the aggregated review can record the trade-off rather than an unexplained disagreement.
