Prevent model-owned source projections from preserving symlinks that can escape the selected ownership root. Document the existing single-family build and runtime proof, and cover the rejection path with a regression test. Signed-off-by: chaofengw <chaofengw@nvidia.com>

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Align model-owned detection with shared-path detection.
_owner_under() returns "" for a path directly under a configured root, and _include_source_path() treats that path as shared. This predicate treats the same path as model-owned because it checks only for None. A root-level shared symlink can therefore abort staging unexpectedly.
Require a non-empty owner here, or add an explicit test and document that root-level symlinks are intentionally rejected.
Proposed fix
- return any(_owner_under(path, root) is not None for root in _MODEL_OWNED_ROOTS)
+ return any(
+ _owner_under(path, root) not in (None, "")
+ for root in _MODEL_OWNED_ROOTS
+ )📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Keep the checks advisory while their signal is calibrated, and preserve intentional family duplication through path-specific instructions and tests. Signed-off-by: chaofengw <chaofengw@nvidia.com>

Background
Model families are independently owned vertical slices. Similar-looking
family implementations may intentionally remain separate so defects, merge
conflicts, validation, and rollback stay family-local.
Static CI can catch known dependency-boundary violations, but it cannot
reliably identify semantic coupling, misplaced family policy, or benchmark
methodology drift. This change gives CodeRabbit repository-specific review
instructions for those judgment-heavy cases and closes a symlink escape in the
existing single-family source projection. The review rules cover both the
current split ownership roots and the consolidated

Notes For Future Readers
CodeRabbit findings are advisory and should identify architecture risks that
require reviewer judgment. The family-isolation CI owns deterministic source,
build, link, and runtime boundary enforcement. Neither mechanism should
encourage deduplicating family-owned code solely because implementations look
similar.
Suggested review order:
REVIEW.md,.coderabbit.yaml, then the sourceprojection guard and tests.
Risk level
Risk rationale: this does not affect shipped model behavior, but the CI check
and review policy apply broadly to future family changes. False positives or
gaps could affect contributor workflow, so the guardrails are focused, tested,
and explicit about the boundary between deterministic enforcement and human
judgment.
