Prompt

After the actor/SHM/Parquet integration test exposed a stale SHM triplet, the user requested leak-cleaner machinery in the pytest harness using Tractor’s existing ownership and lifetime patterns.

Response summary

Added creator-scoped SHM leak tracking to pytest without scanning /dev/shm or treating attachments as owned. The fixture cooperates with normal Tractor teardown, verifies POSIX object identity before fallback cleanup, restores process-local token state, and fails after cleaning a leak. Regressions cover the exact pre-actor-registration allocation window, positional creators, and external attachment safety.
