   Mass Target Revision

   The original ~250 g aluminum target was mathematically unreachable inside the approved envelope. The target was revised to 205–220 g and formally replaced, not quietly kept.

   Balance Band Validation

   The below-midplane mass band was set at 40–48%. The Rev A aluminum assembly calculates to 42.6%, with the center of gravity 0.2 mm above the geometric midplane.

   Adapter Bore Revision

   The internal adapter bore was reduced from Ø22 mm to Ø19 mm, preserving a validated 5.5 mm neck wall around the insert.

   Rev A Geometry Lock

   The exterior profile was locked as the Rev A provisional baseline: 64 mm tall, Ø50 crown carried above the midplane, one continuous machined form.

   Adapter Retention Resolved

   The longest-standing open item on the program is closed. Holding the adapter against rotation and holding it against pull-out are now two separate mechanical joints instead of one overloaded feature. No adhesive in either load path.

   The Check We Did Not Have

   The machine shop's production review caught a part that could not be assembled, and caught it before cutting. The adapter fit its seat perfectly and could never have reached it. The revision that fixes it matters less than the check that should have found it first.
