+## [v1.10.1] — 2026-06-20
+
+### Fixed/clarified — gate integrity (f1 probe, overnight)
+
+The overnight f1 campaign surfaced that the per-cycle gate (`node --check` + smoke)
+is necessary but NOT sufficient, and a sub-agent's self-reported "gate passed" is
+not trustworthy — both misses were caught only by loading the artifact in its
+runtime (the orchestrator's render-verify):
+
+- **`node --check` misses ES-module redeclarations.** A duplicate same-scope
+  `const` (two cycles each declaring `speedN`) exits 0 under `node --check` but the
+  browser ES-module parser rejects it — the game wouldn't boot, yet the cycle
+  reported PASS. dev-cycle Step 4 now requires a **module-load check** (import the
+  changed modules in their module system) for ES-module/browser artifacts.
+- **Visual regressions pass every unit gate.** A cumulative over-exposed-to-white
+  frame passed `node --check` + smoke; only a rendered critique (evolve 5-G)
+  caught it. Rule added: for rich-runtime artifacts, verification MUST load the
+  artifact the way its runtime does (module-load + render/screenshot), and evolve
+  re-checks the gate from recorded facts — it does not take the build skill's word.
+
+plugin 1.10.0→1.10.1. (Docs/spec only; verify.py unchanged at 63.)

+> **Gate integrity (v1.10.1 — earned by the f1 probe).** A static check is
+> necessary but NOT sufficient, and a sub-agent's *self-reported* gate result is
+> not trustworthy — the orchestrator must verify from facts. Two real misses the
+> f1 overnight run surfaced, BOTH caught only by loading the artifact in its real

+>    `node --check + smoke` gate "passed". For an ES-module/browser artifact, also
+>    do a **module-load check** (import the changed modules in their module system,
+>    e.g. `node --input-type=module -e 'import("./src/x.js")'`, or load the page)
+>    — that catches what `node --check` cannot.
+> 2. A cumulative **visual regression** (over-exposed-to-white frame) passed every
+>    unit gate; only a **rendered critique** caught it.
+> Rule: for rich-runtime artifacts (browser/UI/graphics/game), the verification
+> MUST load the artifact the way its runtime does (module-load + render/screenshot
+> critique, i.e. evolve Step 5-G), and evolve re-checks the gate from recorded
+> facts — it does NOT take the build skill's word for "tests passed".
