Part of #1665: batch B6 of the arm D step-2 design. builtins_buf.c and builtins_host.c leave the legacy borrow API and join the migrated-files gate. Storage stays Value**.

strict_shape_contract.py's candidate discovery now also matches list_sort(. This can only widen the audited population, which stays at 190.

Gates (run locally on top of B5)

check result
Ir vs B5 flat on all three benchmarks
tape identity identical
make http builds
jit-smoke pass
jit_diff 257 programs pass
release suite 4220/4221
full ASan suite, detect_leaks=1 4211/4212, leak tally 0
rehearsal suite the same, plus the pre-existing [70d] (#1709)
static gates pass

The one failure in the release and ASan suites is the pre-existing [99d] (#1708).

Built by Codex Cloud; gated locally.

Batch B6 of the arm D step-2 design: builtins_buf.c and builtins_host.c
leave the legacy borrow API and join the migrated-files gate (Codex Cloud
builder). strict_shape_contract.py's candidate discovery also matches
list_sort( (widens the audited population; it is unchanged at 190).

Local gates on top of B5: Ir vs B5 flat; tape identical; jit-smoke;
jit_diff (257); release 4220/4221, full ASan (detect_leaks=1)
4211/4212 with leak tally 0 -- the one failure in each is the
pre-existing [99d] (#1708); rehearsal adds the pre-existing [70d]
(#1709).
