has no automatic feedback upload or telemetry.

Beta limits and verification

Compares stored fields; no CPM recalculation. Only the first project in each
XER is modeled. Activity ID renames appear as delete/add. Driving-path membership
uses stored total float at or below zero as an approximation. DCMA checks 11–14
show N/A with reasons. Review findings against the source schedules.

The Windows suite passed 84 tests, including local real-file coverage. The
packaged app passed isolated-runtime checks with network connections blocked,
including comparison, quality drill-down, saved profiles, and synthetic history.
A separate machine without Python has not yet been tested. Detailed scope is in
verification.

SHA256SUMS.txt records hashes for the ZIP and standalone PDF guide. The verified
EXE inside the ZIP is unchanged from the local v0.3.0 build:
