I read this as an independent Gate18 validation and evidence task - I’ll identify the established gate procedure, verify the immutable candidate before and after isolated source/wheel testing, and append a PASS/FAIL receipt without touching operational state.

The sealed successor is structurally consistent and pins a one-file `gateway/status.py` PID-marker correction over the prior digest. I’m starting the two-lane run with the Golden Path, controller suite, the three exact PID-fix regressions, and runtime-status PID checks; both lanes use the same copied test sources under a read-only, network-isolated sandbox.


The source lane passed 19/19 and wheel provenance confirmed the corrected PID/status and controller modules came from the sealed wheel. The first wheel test sandbox stopped before Python started because its disabled-cache mount destination did not exist; no test was collected or executed. I’m correcting only that harness mount and performing the single substantive wheel test run.


Both substantive lanes are now conclusive: source 19/19 and sealed wheel 19/19. I’m performing the final immutable-candidate and 2,374-entry source-closure check, then writing the new receipt with the two pre-execution sandbox aborts explicitly preserved rather than omitted.


I read this as completed Gate18 evidence delivery - report the verified result and receipt.
