I read this as executing the immutable Task26 Gate18 successor validation - I’ll derive the procedure from the prior receipt, independently verify the candidate and compatibility evidence, run the required network-denied source/wheel tests in disposable profiles, re-verify immutability, and write only a new append-only receipt.


The successor’s independent verifier passes and confirms the Task22-25 records are historical-only. I’m moving to execution with a read-only host root, a new network namespace, disabled pytest/pip caches and bytecode, and temp-only HOME/profile/evidence paths; the source and sealed-wheel lanes will run separately so package provenance is unambiguous.


Both required lanes now pass: 12/12 from current source and 12/12 from the sealed wheel, with wheel import provenance pinned to the disposable installation and the repaired controller hash matching exactly. I’m performing the post-run immutability/parity checks, then I’ll remove the entire temporary profile/install/output tree before sealing the receipt.


I read this as reporting the completed Gate18 execution - I’ll provide the verdict and sealed receipt details.
