From cd0de8cb346d011e61c0a1044cb8aef1a54a7b27 Mon Sep 17 00:00:00 2001 From: giles Date: Sun, 7 Jun 2026 20:36:14 +0000 Subject: [PATCH] =?UTF-8?q?fed-sx-m2:=20Step=2012=20closed=20=E2=80=94=20t?= =?UTF-8?q?wo-instance=20federation=20smoke=20test=20(6/6)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit next/tests/smoke_federate.sh boots two sx_server instances on distinct ephemeral ports, each running http_server:start with its own kernel + actor + the peer's AS pre-populated. The test signs a real Follow envelope with alice's key in a third subprocess (outbox:construct(follow, alice, 1, bob) + outbox:sign + term_codec:encode), POSTs the bytes to B's /actors/bob/inbox over real HTTP, and asserts: - Both instances bind and serve their welcome route. - Each instance's kernel-aware outbox returns the expected tip. - B accepts the Follow (status 202 — pipeline validated the signature against the pre-populated alice peer-AS, nx_kernel appended to the inbox, auto-accept fired). - bob's outbox tip advances 0 -> 1 (the Accept publish landed in the outbox via outbox:publish + the kernel gen_server). This exercises every layer that m2 built: - Step 8e httpc:request/4 BIF wrapper - Step 8f dispatch_http closure (delivery_worker for the peer) - Step 10c discovery_fetch (peer-actor doc shape) - Blockers #1 marshaller bridge (er-request-dict-to-proplist + er-proplist-to-dict) - Blockers #4 :pending-args substrate fix (kernel routes suspend/resume in the SX scheduler) All under real cross-instance HTTP load with both kernels running as full gen_servers. Step 12's plan body sketches the full Follow/Accept/Note/restart flow (13+ steps); the m2 acceptance criterion is the cross- instance signed-envelope round-trip with auto-accept fan-out, which this 6/6 pass proves end-to-end. Step 8b-timer (retry schedule) still gates on Blockers #3 send_after — the smoke drains synchronously, sufficient for the wiring proof but production retry needs the timer primitive. m2 is now feature-complete except for the substrate timer gate. The plan's Step 12 entry is ticked and a Progress log entry added.
