contract(custody-schema): revision 13 — withdraw wrong §4.5 repair attribution (sol r12 F20 residual)

Sol's r12 confirm closed F18/F19 and found one MINOR residual on F20:
rev 12 assigned the terminated ordinary writer's committed-but-unpointed
content to §4.5 repair, but §4.5 enumerates pointers and repairs the
opposite state (pointer present, content absent) — unpointed content is
outside its input, so the §7.10 assertion had no conforming transition.

Per the prescribed correction: the §4.5 repair assertion is removed from
§3.7 and §7.10; the no-upsert assertion stays; the state is what §3.7
and §7.16 already define — inert unpointed content (no pointer, no read
path, no repair transition; a §4.5 cycle run against it changes
nothing), never acknowledged, converging only through the client's
retry as a fresh lock acquisition under a new token that recommits and
completes the pointer upsert. Preamble Revision 13 paragraph added.
