+
+## Summary
+
+Make the Super3 M0 data-env README examples portable by replacing scoped
+named-user `/mnt/3fs/data/lei.song/nemotron` paths with
+`${NEMO_RUN_DIR:-.}/output/super3/...` examples and adding a focused static
+test guard.
+
+## Scope
+
+- `src/nemotron/recipes/super3/milestones/m0_data_env/README.md`
+- Focused static docs test under `tests/recipes/super3/`
+- Task/status docs for `intern_nem_dev_3`
+
+## Boundaries
+
+- No live M0 data prep, HF/dataset download, health baseline run, train/eval,
+  endpoint calls, W&B, cluster jobs, deploy, artifact download, direct
+  `main`/`master` push, or self-merge.
+- Do not touch task150/task152 files, Stage1 SFT docs/config comments, tiny
+  blend files, production data-prep logic, generated artifacts, live-run
+  reports, or benchmark/eval configs.
+
+## Acceptance Checks
+
+- Focused pytest for the M0 data-env docs guard.
+- `py_compile` and Ruff on touched test files.
+- Scoped static grep proving the README no longer contains
+  `/mnt/3fs/data/lei.song/nemotron`.
+- `git diff --check` and `git diff --cached --check`.
+- Added-line live-surface scan limited to docs/static-test examples.

+
+- Accepted PM assignment and created branch
+  `intern_nem_dev_3/task153_super3_m0_data_env_docs_path_portability_s1`
+  from `origin/main` at `1e00d0f2559dd40c9ce396f5b7d0a539ce509f3a`.
+- Updated M0 data-env README run and health-check examples to use
+  `${NEMO_RUN_DIR:-.}/output/super3/m0_data_env_foundation/smoke-20260516`.
+- Added focused static test coverage for removing the named-user 3FS path and
+  preserving portable output/input examples.
+- Verified focused pytest guard, `py_compile`, Ruff, scoped static grep,
+  added-line live-surface scan, and `git diff --check` before staging.
+- Opened PR #260 to `main`: https://github.com/songCNMS/Nemotron/pull/260.

+## Working Notes
+
+- The scoped M0 README path contract is
+  `${NEMO_RUN_DIR:-.}/output/super3/m0_data_env_foundation/smoke-20260516`.
+- This task is docs/static-test only; production M0 data prep and health
+  baseline logic are intentionally untouched.
