gstack's /cso audit can test its own security repairs again. Patching a read-only snapshot file kept failing, so every repair check stalled. Now the helper makes the file writable, then restores its mode.

Runtime ID

runtime-plan now hands verify the runtime ID it accepts

runtime-plan returned the stack aliasverify refused it
It returns the qualified ID, such as node-24.4.0-amd64verify runs
Any other profile gets an error naming the expected IDno attempt counted

A second bug stacked on top: the planning step handed out a stack name that verify refused. Now it returns the exact runtime ID. Any other profile gets an error naming the right one, before the attempt counts.

Clock

Every /cso helper reply now says how much time is left

remainingSeconds comes back from start, submit, scan, verify, inspect and six more commands
The count ends where scan, verify and record-review start refusing with DEADLINE
The final minute stays free for submit and finish

Long /cso runs now finish on time. One run worked 25 minutes past its findings and was killed before its report was done. Now every helper reply carries the seconds left. The count ends a minute early, so finishing always has room.

Deadline

Under two minutes left, /cso stops and finishes

The skill starts only work that fits in the time left
Below 120 seconds it stops waiting and calls finish
Your own agent driving gstack-cso gets the same count, and inspect refreshes it with no side effects

The skill now follows that clock. It starts only work that fits. Under two minutes, it stops waiting and finishes the report. If your own agent drives the helper, it gets the same count in every reply.
