feat(dom): prove INT-08 reconciler runs end-to-end; ship the e2e harness#680
Merged
Conversation
…ess (Refs #183) The dom.affine header said "RUNTIME blocked by #255; no runtime e2e harness is shipped until then (a harness that cannot pass would be dishonest)". #255 was fixed in PR #257 — and the harness now CAN pass, so per the header's own bar, it ships: - affinescript-dom/e2e/run.sh — concatenates src/dom.affine + a driver `main`, compiles to core-WASM, runs under Node against an Int-handle host DOM, asserts the mutation log + final tree. Skips loudly (exit 0) when the compiler or node is absent; AFFINESCRIPT_BIN overrides the binary path for CI. - affinescript-dom/e2e/driver_main.affine — mounts <div id=app class=old>["hello", <span>["x"]]</div>, then reconciles to <div id=app title=t2>["world"]</div>. Exercises every loop-bearing path (the #255 class): render attr+children loops, patch_attrs add+remove (attr_has), and the `while` child-reconcile loop (in-place text patch + surplus-child removal). The affine discipline is load-bearing in the driver itself: `mount` consumes its tree, so reconcile takes a fresh copy — reuse would be a use-after-move type error. - affinescript-dom/e2e/dom_host.mjs — the host: Int-handle node map, mutation log, hard assertions (title added, class removed, text patched in place, span removed, reconcile returned the in-place handle). Observed run (2026-07-07, node 26, dune 3.24 build): query(#root) … setAttr(#2,title=t2) removeAttr(#2,class) setText(#3,"world") remove(#2,#4) <#root> └ <div id="app" title="t2"> └ "world" ALL ASSERTIONS PASS Docs reconciled to VERIFIED (dom.affine header; ECOSYSTEM satellite + INT-08/INT-11 rows; TECH-DEBT INT-08; bindings-roadmap DOM row). INT-11's remaining leg is browser-host parity (this run is Node). Gates: dune build exit 0; doc-truthing OK; soundness ledger all-5 OK; e2e harness exit 0 from the branch's own build.

What
dom.affine's header said "RUNTIME blocked by #255; no runtime e2e harness is shipped until then (a harness that cannot pass would be dishonest)." #255 was fixed in PR #257 — and the harness now can pass, so per the header's own bar, it ships. Refs #183 (INT-08).The proof
