Drew T 4cf531beea docs(cookbook): §399 — four levers from the final S69 round, harvested late

Caught by Drew asking whether the last waves were harvested. They were not: I
banked 1 of 5 (§398b) and left four lever sets in the notifications. Also found
two paid-for MATCHes that were never staged or gated.

(a) a fence BETWEEN two prologue loads, where source reorder does nothing —
    the order is fixed before statement order matters (md_MAIN_013/func_800CB56C)
(b) SINK a call into BOTH arms and let cross_jump keep only the jal suffix;
    88ins/close86 -> 92/13, then §3-T2 field order let each sh $zero fill an lhu
    load-delay. Duplicate in source so the compiler merges, rather than writing
    the merged form yourself (ov_SC07_001/func_8017EDC0)
(c) a $v0->$a0->$s3 DOUBLE COPY is a two-pseudo tell: SImode temp for the compare
    + separate HImode var for the tail (70->37); plus §195-N precondition 5 —
    nesting `return 1` with ONE trailing `return 0` blocks jump.c's store-flag
    transform so reorg fills both delay slots (18->0) (ov_SC02_017/func_8018347C)
(d) the re-tie as a BIV KILLER: a second set makes n_times_set>1 so loop.c
    refuses the pseudo as a biv, killing the combined address giv. volatile was
    worse, a dead read did nothing (ov_SC07_001/func_8017E4DC)

(d) makes THREE distinct uses of the zero-byte re-tie in one session — §380
un-hoists a move_movables invariant, §393 kills the scheduler's birthing boost,
§399d denies a biv. One line, three passes: when a single-set pseudo is being
treated specially, give it a second set.
