PunchOp × SMTP and header point tools

What PunchOp aims to add
An incident-first investigation: identify the sending system, assemble available evidence, expose missing data and recommend the next useful check.

The scopes are not equivalent. This product may provide a source, sending capability, signal or control used during the investigation.
Documented scope limit
Isolated checks rather than persistent multi-source cases; evidence only from what you paste or test.
PunchOp hypothesis proximity
High for validating one hop or auth result; low for reconstructing application → relay → export timelines.
