The awaits-user clause could never fire. It asked the live projection for
`attention`, which needs a prompt whose resolution is still `pending` -- but
teardown CANCELS that prompt a few phases after it writes the marker. By the next
launch the evidence is gone, for precisely the sessions the clause was written
for. QA measured the injection still being offered and then resumed.
This is the same shape as the leaf-drift bug: state read after teardown is not the
state that justified the marker. The discriminator, now applied across the whole
predicate:
- a fact teardown itself destroys or mutates must be CAPTURED on the marker
while it is still true;
- a fact that evolves on its own must be RE-DERIVED at read time, never
snapshotted.
So `awaitsUser` is now recorded at teardown and the predicate reads the recorded
value. Teardown still declines to mint a marker for such a session, so the
recorded flag is the second line rather than the only one.
Audit of every other clause against the same test:
- turn id (captured) -- teardown rewrites turn STATE but never the id. Correct.
- provider handle root (captured) -- the close path appends a resumed link, and
appendAgentSessionProviderHandleLink refuses one that changes the root, so the
root is invariant under exactly the mutation that broke the key. Correct.
- turn state (re-derived) -- DELIBERATE exception, stated here rather than left
implicit: we are not reading the state that justified the marker, we are
reading teardown's receipt that it settled the turn. A turn still `running`
means eviction never finished, and we refuse. Correct, and intentionally so.
- lease reconciled / released / handoff stage (re-derived) -- these answer a
different, launch-time question: may this host take the lease NOW. The
teardown-time value would be meaningless, and `unreconciled` is cleared by
this launch's own reconciliation. Correct.
- adapter support, marker TTL, marker consumption (re-derived) -- all evolve
independently of teardown. Correct.
Only awaitsUser was on the wrong side.
