FABRIC-2.md: record item 4.6's effort number, per §10

Recorded in item 4.6's own closure entry in FABRIC-2.md, not literally
under FABRIC.md's §10 -- matches how item 4.2's effort number actually
lived (inside that item's own punch-list entry), and respects
FABRIC.md's own closed/no-further-edits rule. Same format as item 4.2's
report: session time, lines changed split FORTH vs. C surface, file
count.

 - [ ] **5.1 — Re-run the DoE on the new substrate.** A green POST suite is not evidence that
   determinism holds under the Stadium migration — needs its own campaign. Not started.
