The register half of 619de97a, which was silently dropped — its heredoc
invoked `python`, which does not exist on this box (`py` does), so the edit
never ran while the commit still reported success. Worth noting as its own
small lesson: a shell that fails inside a compound command can leave a commit
claiming work it did not do.
Content of the correction, from the AP-22 architecture review: the retirement
commit's "Headless.Tests 89/89 exercises the site-3 copy" is false, disproved
by sabotage — restoring the invented cylinder in both static sites left the
whole suite green. Two of three deletions, including the headless-only one,
rest on the installed-DAT reachability proof alone. Also recorded: sites 2/3
used the wider `Radius > 0f` guard (differing from site 1's over the DAT by
exactly one Setup, 0x02001657, denormal radius 1.3e-39); the load-bearing fact
is that all 1,652 no-primitive Setups carry Radius exactly 0; and retail's
report_object_collision does read GetHeight for the quadrant field, which is
not a refutation of the FindObjCollisions shape-dispatch claim.
Reachability is now independently reproduced by four decoders plus
tools/SetupInspect.
