load_config() and read_raw_config() now cache their result keyed on the config file's (mtime_ns, size). On cache hit they return a deepcopy of the cached value, skipping yaml.safe_load + deep-merge + normalize + env-var expansion entirely. save_config() + migrate_config() write via atomic_yaml_write which produces a fresh inode, so stat() sees a new mtime_ns and the next load repopulates automatically — no explicit invalidation hook needed. Measured per-call cost: load_config() cold: 13.3 ms load_config() cached: 0.23 ms (57x faster) read_raw_config() cached: 0.13 ms A single gateway turn hits the config 5-15 times (session context, auxiliary client resolution, memory config, plugin hooks, approval lookups, per-tool settings). That's 65-200 ms/turn of pure YAML re-parsing on main. After this change: 1-3 ms/turn. Also migrates gateway/run.py's 6 direct yaml.safe_load(config.yaml) call sites through _load_gateway_config, which now shares the read_raw_config cache when _hermes_home agrees with the canonical config path. The direct-read fallback is retained for tests that monkeypatch gateway_run._hermes_home without touching HERMES_HOME. Safety: - load_config() returns a deepcopy on every call; the 67+ call sites that mutate the result (cfg["model"]["default"] = ..., etc.) can't corrupt the cache. - save_config() / atomic_yaml_write bump mtime, naturally invalidating the cache for the next reader. - Cache is keyed on str(config_path), so HERMES_HOME profile switches don't collide. Verified: - 112 config tests pass (test_config, test_config_env_expansion, test_config_env_refs, test_config_drift, test_config_validation, test_aux_config). - 87 gateway tests pass (test_verbose_command, test_session_info, test_compress_focus, test_runtime_footer, test_resume_command, test_reasoning_command, test_approve_deny_commands, test_run_progress_interrupt). - Live hermes chat smoke — 2 turns + /model switch + tool calls, zero errors in agent.log.
