acl: hardening suite (+25) — diamonds, cycles, validation, audit save/restore 
New adversarial/cross-phase coverage: diamond resource+group hierarchies
(deny wins per path), chain inheritance + leaf deny, cycle termination,
multi-peer delegation, fact validation, audit snapshot/restore round-trip.
Adds acl-validate-facts/acl-facts-valid? (schema) and acl-audit-snapshot/
restore!/copy (audit). Fixed acl-audit-restore! rebuilding the live log via
map (append! silently no-ops on map-derived lists).

Suite is prover-free: a substrate JIT bug loops the recursive proof
reconstructor on deep chains in warm processes (documented in Blockers);
acl-permit? is unaffected. 145/145.

;; lib/acl/tests/harden.sx — adversarial / cross-phase hardening.
;;
;; Diamond hierarchies, conflict resolution where deny must win through every
;; path, chain inheritance, cycle termination, multi-peer delegation, fact
;; validation, and audit save/restore.
;;
;; PROVER-FREE BY DESIGN: this suite calls only acl-permit? (which runs in
;; compiled Datalog, safe at any depth) plus pure data ops — never acl-explain /
;; acl-prove-d. The SX-side proof reconstructor recurses, and once the kernel
;; JIT-compiles it (after the explain/fed suites warm the process) it loops on
;; chains deeper than ~3 (substrate JIT bug — see plan Blockers). Proof
;; reconstruction is covered by tests/explain.sx (and federated proofs by
;; tests/fed.sx), both of which stay under the warm-process depth threshold.
