instrument blind to the effect, not a corrected number Per Captain Bob's correction (heartbeat tick counter is the sole canonical clock, not wall-clock), added HEARTBEAT-TICKS@ and re-ran the ACL-TTL overhead measurement using tick deltas. Diagnostics confirmed the counter is a FORTH-level colon-word-dispatch counter (frozen at idle, jumps with real work) -- not a wall-clock proxy. A pilot pair (amd64, seed 12345, 30 reps, ACL disabled vs enabled) produced byte-identical deltas (261064 ticks both runs): acl_recheck() runs at the C dispatch level and doesn't change which/how many colon words execute, so it's invisible to a counter gated on colon-word-entry count. Root-caused, not proceeding to the full 18-cell campaign -- every cell would read +0.00% by construction. Section P's wall-clock numbers stand as the best estimate on record pending a instrument that can see per-dispatch cost rather than control-flow shape.

FORTH personality files loaded by the VM at boot. A capsule is an immutable, content-addressed payload; its XXHash64 hash is its identity. Any mutation changes the hash and the birth protocol rejects the image.
