 CI targets chain lint → build → test sequentially. A failure in any stage stops the pipeline.
 
+### Pre-PR Checks
+
+Before pushing a PR, run:
+
+```bash
+make pre-pr
+```
+
+This runs all checks in order: lint → build → test → content validation → fixture staleness. Total runtime ~2.5 minutes (incremental build), under 3 minutes clean.
+
+For branch-specific checks:
+
+```bash
+make pre-pr-server      # Server changes: lint, build, test, fixture staleness
+make pre-pr-client      # Client changes: lint, build, test
+make pre-pr-content     # Content changes: schema + cross-reference validation
+```
+
+If `pre-pr-fixtures` fails, your protocol changes require fixture regeneration:
+
+```bash
+make fixtures
+git add client/tests/fixtures/
+git commit -m "chore(fixtures): regenerate for protocol vN"
+```
+
+The fixture staleness check is a **blocker** (exit 1) — stale fixtures cause false positive client tests.
+
 ### Clean
