- Drew's sequencing (agreed): do the 45 small jr families FIRST — not for byte-weight (~+1% instr,
129K ins) but to de-risk + harden the §8 x134 pipeline before the heavy Fable5 cores bet on it.
- decisive technical reason: jtbl_carve only built the single-jtbl carve; func_8012ACE0 is now
matched in all 133 siblings, so family #2 forces the multi-jtbl address-ordered `ld_interleave
--order` carve -> build & prove it on cheap 30-ins targets first. Also needs no Fable5.
- guardrail kept explicit: small tier = MEANS (harden pipeline + build multi-jtbl), NOT the
objective; the 191 heavy jr families (5.53M ins) remain THE byte-weight target -> pivot after.
- CURRENT_PHASE.md SESSION-3 checkpoint updated to Stage 1 (small + build multi-jtbl) -> Stage 2
(heavy 191, Fable5 un-paused). decision-log addendum with the forcing-function wiki lesson.
