The two Common registration entrypoints now share one payload publisher and one receiver-diagnostic bump, so keep the source witness aligned with that single audited site. Claude-Session: https://claude.ai/code/session_011dhBmdn4vGgNibjo3oZqTo
Install the handle-recycling tick hook at the shared reservation entrypoint, add a fresh-process runtime witness for that path, and keep the extracted native-registration fixture buildable with an inert event-pump seam. Claude-Session: https://claude.ai/code/session_011dhBmdn4vGgNibjo3oZqTo

Make reserved-id retirement domain-aware without breaking private cleanup.
begin_retirement can retire a private-domain Reserved slot by numeric ID alone. finish_retirement then makes that ID reusable while the private owner still holds its payload.
Do not add only a self.domain() guard. reserve_handle_id_in_domain and the Net lifecycle call free_handle_id for private reservations, so that guard would make private cleanup a no-op and leak reserved IDs. Add an expected-domain retirement path, keep free_handle_id for the default domain, and pass the private domain through a domain-aware free function. Alternatively, return the full identity and use begin_retirement_of. Test both cross-domain rejection and private-domain reserve/free/reuse.

Wire the Common quarantine drain into the outer-tick lifecycle.
remove_payload places retired Common identifiers in NativeQuarantine::NextDrain. The existing FFI tick hook drains only the FFI registry, not drain_quarantined_common_handles. When the 64K Common queue fills, finish_retirement marks later slots Abandoned, and register_handle can eventually panic after exhausting the Common ID band.

Native registries identify entries with recyclable integers. A managed receiver wrapper could otherwise refer to a later registration that reused the same number, and native teardown could overlap an operation without a shared lifetime contract.
This PR adds that prerequisite contract:
perry-native-registration, below runtime and FFI in the Cargo graph;perry-ffikeeps its public API through re-exports, while FFI handles, Common handles, Events emitters, and net reservations use the shared protocol;The PR does not publish managed wrappers or claim a cc performance change. It establishes the lifetime and identity contract required by the later receiver migration.
