test(physics): S6 — the camera provably reaches both PerfectClip TOI tails; contained, not dormant

AP-83/AP-91 claimed no current mover sets PerfectClip. The containment
proof found the opposite and the contract's honest-fallback fired: the
camera probe (the sole production setter) reaches BOTH ACE-derived
tails live — the viewer exemption is creature-only, the shadow-list
walk is unconditional, and static scenery with authored primitives is
a real non-creature population. Every reach is now recorded
(camera-live silently; any non-viewer mover loudly, one-shot), so a
future flag change cannot exercise unreviewed ACE-derived math
silently. Four tests drive the camera's exact call shape both ways;
the sabotage was intelligently adapted — there was no existing cut to
disable, so it flips the one axis the proof depends on (IsCreature)
and asserts reachability inverts. Both register rows rewritten
CONTAINED-not-dormant with severity narrowed to camera-feel (the probe
never commits a PhysicsBody).

Landing note: diagnostics-only diff (two guard calls + counters +
corrected stale comments), verified directly by the session lead
rather than a review cycle — the review budget went where behaviour
changed tonight.

Campaign S CLOSES with this landing: S1A/S1B/S2/S4/S5/S6 done, S3
cancelled, three user-passed gates, one honestly-open item — AD-66's
reland, twice self-refused by its own stability gate, blocked on the
#341 codegen-shape measurement instability whose ABA evidence and
first discriminating experiment are filed.

Clean-room suite: 11,257 passed / 6 skipped / 0 failed.
