Project P.I.T.T. Cannon Not Working: Diagnostic Checklist
Cannon Not Working: Diagnostic Checklist: A late-stage delivery fails at its destination? Check that the item arrives intact and actually enters the target.
A late-stage delivery fails at its destination? Check that the item arrives intact and actually enters the target. An apparent hit is not proof of Cauldron acceptance; do not increase firing frequency to conceal a bad landing. These are diagnostics, not a guaranteed fix.

Separate the symptom from the assumed cause
A late-stage delivery fails at its destination. Inspect the receiving area as well as the launch point. The older Phase 4 guide uses Cannons, but also describes inconsistent transport for some inputs.

Patch and evidence boundary
Older full-release Steam player evidence uses Cannons in Phase 4 delivery chains. Targeting, capacity and timing are not treated as universal. If the failure persists, retain a before-and-after capture rather than asserting a missing level, an undocumented key or a numerical setting.
