+title: "A-3: Evidence-language guard — pre-commit on docs/evidence/** rejecting UI/e2e claims with no
+  Playwright artifact referenced"
+summary: >-
+  Adds a pre-commit hook (.pre-commit-hooks/reject-evidence-ui-claims.sh) to omniclaude that enforces
+  evidence-language honesty on docs/evidence/** markdown files. Any doc containing "UI POST", "click",
+  "full chain live", or "end-to-end" must also reference a Playwright artifact; otherwise the commit is
+  blocked. Root cause: PROCESS_FAILURE_RETRO.md §3.A (top-10 failure #1) — the 2026-06-11 19:27Z evidence
+  doc overstated UI coverage when only curl was run.
