New gen_server exports add_actor/3, publish_to/2, log_tip_for/1, actors/0, state_for/1, bucket_for/1, with_projections_for/2 — each is a thin gen_server:call delegating to 1a's pure-functional bucket API via fresh handle_call branches. Existing single-actor calls (publish/1, log_tip/0, with_projections/1) route through bucket 0 unchanged. Per-actor mailbox sharding (one gen_server per bucket so distinct- actor publishes don't serialise on a single mailbox) is forward- looking — deferred to Step 4 where the per-actor HTTP routing makes it actually load-bearing. Single-mailbox serialisation is fine for Steps 1-3. nx_kernel_multi.sh extended from 17 to 26 cases (gen_server load, start_link bucket-0 seed, add_actor/3 dup detection, publish_to/2 per-actor isolation, interleaved publishes, no_actor error, state_for + with_projections_for round-trips). 134/134 across 12 nx_kernel- adjacent + http suites. Erlang conformance 761/761 preserved.
