Long-lived gateways under heavy cron/build workloads grow steadily (~18 MB/hr post-phantom-dispatch-fix) and eventually need a restart-or-OOM. Four retention sites, all confirmed live on current main: 1. _evict_cached_agent() (/model, /reasoning, codex-runtime, /undo, etc.) popped the cache entry without releasing the agent's OpenAI client, httpx transport, SSL context, or conversation history. Only /new cleaned up first. Now releases clients on a daemon thread, matching _enforce_agent_cache_cap. 2. _release_evicted_agent_soft() now clears _session_messages after release_clients() — tool outputs (file reads, terminal output, search results) can be tens of MB per 100+-tool-call session; the list is rebuilt from persisted session JSON on resume, so dropping it on soft eviction is safe. 3. The session-expiry watcher (permanent finalization) now drops the session's per-session control dicts (_session_model_overrides, _session_reasoning_overrides, _pending_approvals, _update_prompt_pending, _pending_model_notes). These leaked one entry per session per gateway lifetime. NOTE: this is the session-finalize path, NOT idle agent-cache eviction — an idle-evicted session is still alive and rebuilds its agent from these overrides, so pruning them there would silently reset a user's /model choice. 4. _tool_defs_cache is now bounded (_TOOL_DEFS_CACHE_MAX=8) with oldest-first eviction instead of growing unboundedly across the distinct toolset/config fingerprints a gateway sees over its lifetime. Salvaged from #25318 by Michael Steuer (@mssteuer); fix 3 redirected from the idle-sweep to the session-finalize lifecycle, magic number 8 lifted to a named constant, test ported.
