Entries are evicted one tick late: the pool compares with > where it should use >=. Confirm before patching.

The fix is one character, but it needs a regression test with a frozen clock. Hand the test to a subagent and patch the pool meanwhile.

Write a regression test proving a pool entry expires exactly at ttl, without sleeping.

Parent wants a regression test for pool entries expiring on a boundary. Sleeping in a test is flaky, so look for a clock fixture already in the suite.

Added tests/test_pool_expiry.py covering the boundary and the one-second-past case, using the existing frozen_clock fixture.

Resolved. Expiry now uses >= so an entry dies exactly at ttl; the subagent's tests/test_pool_expiry.py covers the boundary.
