-### 1b. Runtime smoke test (MANDATORY)
+### 1b. Zero warnings policy (MANDATORY)
+
+Before pushing, verify the branch has **zero lint warnings**. Any warning
+must be either fixed or suppressed with a commented justification.
+
+**For client/visual branches:**
+```bash
+gdlint client/scripts/ client/ui/ 2>&1
+```
+
+If warnings remain, fix them before pushing. For warnings that cannot be
+fixed (e.g. intentional long lines in data literals), add a `# gdlint:
+ignore` comment with a reason.
+
+**For server branches:**
+```bash
+cargo clippy -- -D warnings 2>&1
+```
+
+**For CI/tooling branches:**
+```bash
+ruff check tooling/ 2>&1
+```
+
+The goal is zero warnings in the pre-push output. Advisory warnings that
+the pre-push hook reports as "(advisory, not blocking)" should still be
+zero — they are advisory only because we haven't enforced them yet.
+
+### 1c. Runtime smoke test (MANDATORY)
 
 Before pushing, verify the game actually runs. This is non-negotiable —
 Sprint 28 proved that code review without runtime testing misses critical

 If script errors appear in the branch diff files, flag them immediately
 before spawning reviewers — no point reviewing code that doesn't parse.
 
+### 0c. Zero warnings check
+
+The project enforces a **zero warnings policy**. Before spawning reviewers,
+check if the branch introduces lint warnings:
+
+- **client/visual:** `gdlint client/scripts/ client/ui/` should report 0 issues
+- **server:** `cargo clippy -- -D warnings` should be clean
+- **ci/tooling:** `ruff check tooling/` should be clean
+
+If warnings exist, note the count in the review output. Reviewers should
+flag any **new** warnings introduced by the branch as `warning` severity.
+Pre-existing warnings are not PR blockers but should be tracked for cleanup.
