Robert Allan JamesandClaude Sonnet 5 6e7323b3b8 ACL-TTL overhead: paired 18-cell measurement complete, FABRIC-2.md Section P ...

Full 18-cell paired campaign (9 arch/seed pairs x ACL disabled/enabled)
complete: 8,640/8,640 rows, all 16 cfg values x 30 each in every cell,
zero errors. Confirmed capsules/zuse.4th's ACL-ZUSE-BOOT self-pin bug
(self-pin placed inside its own colon definition, causing a genuine
forward-reference failure) is isolated from the core ACL enforcement
mechanism -- verified via live VM state query on multiple cells that
ACL-INIT-PRIMITIVES and EXEC/BYE pinning both complete correctly
regardless.

Result: +5.30% pooled overhead, +4.42% unweighted mean across the 9
pairs (sd 6.77%), paired t=2.043 (df=8) -- not significant at p<0.05.
Documented honestly as a real positive trend that doesn't establish a
precise percentage with confidence, given wall-clock timing's noise
floor is comparable to the effect size -- unlike the original ACL-RWT
campaign's VM-internal tick-counter methodology. A tighter measurement
(more replications, or reading a VM-internal counter directly) is
scoped as a next step, not attempted here.
