Define a relation through the UI (metamodel editor surface 1, completing it):
POST /meta/new-relation creates a relation-post (is-a relation, :rel metadata) and
registers it via a runtime concat onto host/blog-rel-kinds — safe because the serving
handler has the IO resolver installed. /meta gains a '+ Relation' form (name, label,
symmetric). Verified: define 'Blocks' (symmetric) -> Relations(5), its editor renders on
edit pages, kind-spec + symmetric correct; auth-guarded.
SESSION-SCOPED: the relation-post + edges persist durably, but the rel-kinds registry
entry is lost on restart because load-rel-kinds! must stay UNROLLED — it runs at BOOT
where it is JIT-compiled but the IO resolver is NOT yet installed, so a dynamic loader
(map/reduce over instances-of 'relation' with a durable read per item) silently returns []
(verified: dynamic -> /meta Relations(0)). The serving-JIT HO-callback-perform fix only
engages with the resolver = serve time. Flagged to sx-vm-extensions (NOTE-render-diff-for-
vm-ext.md); they ACKed + are tracking the boot-resolver fix. Reverted the dynamic loader,
kept the unroll with a comment explaining why.
VERIFICATION NOTE: the full blog suite could not complete — the box is under extreme
contention from sibling loops (load 14, multiple full conformance + erlang/vm-ext rebuilds)
and the Datalog-heavy 140-test suite times out even at a 1800s cap. Verified instead two
ways: (1) live-path HTTP (real route + auth + editor render, ephemeral SX_SERVING_JIT=1),
(2) a focused in-process eval of the create-relation core (exists/is-a/kind-spec/symmetric/
registry-len = true,true,true,true,5). Prior full run was 140/140; changes since are purely
additive (handler + form + route + 3 tests). Re-run the blog suite when the box is quiet.

- conformance.sh [suite] runs ONE suite (filters the SUITES array so result-parser
indices stay aligned; all MODULES still load). 'conformance.sh sxtp' = 0.3s vs ~8min.
- lib/host/live-check.sh: non-browser live smoke — boot ephemeral host, login, seed a
post (exercises form-ingest write), print status|content-type|body-head per path,
assert reads are text/sx + no JSON leak + no 5xx. The counterpart to run-picker-check.sh.
- plans/NOTE-render-diff-for-vm-ext.md: defer host_render_diff (JIT-vs-interpreter
regression oracle) to the sx-vm-extensions loop — it's their fix's oracle, not a host
feature; building it from loops/host would fork JIT-engine understanding.
