I read this as a read-only independent closure audit - I’ll recompute the artifacts and bindings, run the immutable verifier, then reproduce the sealed wheel-first bootstrap import from outside the worktree and return one verdict.


The artifact layout and verifier contract are now identified. I’m checking the independent invariants the verifier may not cover, especially stale runtime/package bindings and the r23 import regression path.


The r23 regression is closed: with only the sealed two wheels followed by controller-source on `PYTHONPATH`, the worker imports successfully from `/tmp`, and the boundary module is hash-bound in the exact closure. I’m completing the remaining external target and authority binding checks before issuing the verdict.


I read this as a completed read-only closure audit - reporting the verified verdict.
