Step 7c made outbox depend on follower_graph + delivery, breaking
four tests that didn't load those modules. Background gate
revealed the failures after 7c had already been pushed.
Loads added:
auto_accept.sh — epoch 12: delivery (follower_graph
was already loaded at epoch 10)
nx_kernel_multi.sh — epochs 5+6: follower_graph + delivery
(existing modules shifted: outbox 5->7,
nx_kernel 6->8). Check 6 -> check 8.
http_publish.sh — epochs 100+101: follower_graph + delivery
(high epoch numbers to avoid collision
with test epochs at 10+)
http_publish_fold.sh — epochs 100+101: same pattern
All four green at 9/9, 26/26, 10/10, 10/10. No behaviour change
in outbox or downstream code; pure test-setup follow-up to 7c.
Conformance 761/761 (confirmed post-7c).
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.
State shape becomes [{actors, [{Id, Bucket}, ...]}, {next_actor_seq, N}]
with ActorBucket = [{key_spec, KS}, {actor_state, AS}, {log, L},
{projections, [Name]}, {next_published, N}]. Pure-functional multi-
actor APIs (new/0, add_actor/4, has_actor/2, actors/1, actor_count/1,
publish/3, per-actor accessors, with_actor_projections/3) join the
legacy single-actor accessors, which now read from the first bucket.
Every M1 test continues to pass via bootstrap:start/3 -> new/3 ->
first-bucket lookup.
Local has_keyed/find_keyed/set_keyed/set_bucket helpers cover the
keyed-list ops since lists:keymember/keyfind aren't registered in
this substrate.
next/tests/nx_kernel_multi.sh 17/17. M1 nx_kernel-adjacent suites
green (bootstrap_start 10/10, nx_kernel_server 11/11, http_publish
10/10, smoke_app_pure 12/12, http_post_format 13/13, http_publish_fold
10/10, http_marshal 10/10). Erlang conformance 761/761 preserved.
Blockers entry added for pre-existing http_server_tcp.sh 0/5
regression (78eae9ef left dead helper references in runtime.sx:1593) —
substrate-side, out of m2 scope, confirmed pre-existing by reverting
1a's changes and re-running.
