+# APPLY_PR_LEVEL_12_9_NETWORK_USAGE_SAMPLE_STANDARDIZATION
+
+## Apply Summary
+Applied standardized network import usage across targeted phase-13 samples.
+
+## Execution Result
+- All targeted samples now import via `src/engine/network/index.js`
+- No deep/legacy network paths remain in targeted files
+- No runtime behavior changes detected
+
+## Validation Evidence
+- import/path resolution: PASS
+- network runtime boot: PASS
+- transport/session lifecycle: PASS
+- authoritative runtime: PASS
+- replication/apply: PASS
+- 2D regression smoke: PASS
+
+## Roadmap Update
+Marker-only update applied:
+- `network usage standardization`: `[ ]` -> `[x]`
+
+No wording, structure, additions, or deletions were made.
+
+## Acceptance
+All acceptance criteria satisfied with execution-backed validation.
