* fix(fast): default /fast to session scope on CLI and gateway
Completes the session-first policy from #67946 for the /fast toggle
(the remaining half of #54084). A bare /fast fast|normal now applies to
the current session only; --global persists agent.service_tier to
config.yaml.
Gateway: new _session_service_tier_overrides dict (registered in
_CONVERSATION_SCOPED_STATE so /new clears it) resolved at both agent
turn sites via _resolve_session_service_tier(); the /fast handler and
its choice picker apply session overrides and evict the cached agent.
The TUI config.set fast path was already session-scoped.
CLI: /fast parses --global (parity with /reasoning); bare toggles
mutate self.service_tier only.
* fix(sessions): /new resets model, reasoning, and fast to config defaults
/new and /reset are full conversation boundaries: session-scoped
runtime overrides do not carry into the next session (#48055, #23131).
CLI new_session(): clears the one-turn model restore, re-derives
service_tier from config, and — when the session's model differs from
the config default — switches back via the shared switch_model()
pipeline (live agent swap included; best-effort so an unreachable
default never blocks /new).
TUI _reset_session_agent(): stops forwarding model_override /
create_reasoning_override / create_service_tier_override into the
rebuilt agent and pops the pins so later rebuilds can't resurrect
them. The gateway already cleared its per-session overrides via
_clear_conversation_scope on /new.
Cross-session contamination stays impossible: nothing here touches
process-global env or other sessions' pins.

PR 2362cc468 ("fix(gateway): enforce env variable template expansion
on runtime config loaders") refactored `_load_service_tier` to read
config via the new `_load_gateway_runtime_config` wrapper instead of
opening `_hermes_home/config.yaml` directly. The
`test_run_agent_passes_priority_processing_to_gateway_agent` test still
only stubbed `_load_gateway_config` (the inner loader), so the runtime
wrapper saw an empty config and `_load_service_tier` returned None,
breaking the test:
FAILED tests/gateway/test_fast_command.py::test_run_agent_passes_priority_processing_to_gateway_agent
- AssertionError: assert None == 'priority'
Fix: also stub `_load_gateway_runtime_config` to return the expected
`agent.service_tier=fast` config, so the test once again drives the
priority routing path it was written to verify.
Confirmed reproducing on current main before the patch and passing
after.
Smart model routing (auto-routing short/simple turns to a cheap model
across providers) was opt-in and disabled by default. This removes the
feature wholesale: the routing module, its config keys, docs, tests, and
the orchestration scaffolding it required in cli.py / gateway/run.py /
cron/scheduler.py.
The /fast (Priority Processing / Anthropic fast mode) feature kept its
hooks into _resolve_turn_agent_config — those still build a route dict
and attach request_overrides when the model supports it; the route now
just always uses the session's primary model/provider rather than
running prompts through choose_cheap_model_route() first.
Also removed:
- DEFAULT_CONFIG['smart_model_routing'] block and matching commented-out
example sections in hermes_cli/config.py and cli-config.yaml.example
- _load_smart_model_routing() / self._smart_model_routing on GatewayRunner
- self._smart_model_routing / self._active_agent_route_signature on
HermesCLI (signature kept; just no longer initialised through the
smart-routing pipeline)
- route_label parameter on HermesCLI._init_agent (only set by smart
routing; never read elsewhere)
- 'Smart Model Routing' section in website/docs/integrations/providers.md
- tip in hermes_cli/tips.py
- entries in hermes_cli/dump.py + hermes_cli/web_server.py
- row in skills/autonomous-ai-agents/hermes-agent/SKILL.md
Tests:
- Deleted tests/agent/test_smart_model_routing.py
- Rewrote tests/agent/test_credential_pool_routing.py to target the
simplified _resolve_turn_agent_config directly (preserves credential
pool propagation + 429 rotation coverage)
- Dropped 'cheap model' test from test_cli_provider_resolution.py
- Dropped resolve_turn_route patches from cli + gateway test_fast_command
— they now exercise the real method end-to-end
- Removed _smart_model_routing stub assignments from gateway/cron test
helpers
Targeted suites: 74/74 in the directly affected test files;
tests/agent + tests/cron + tests/cli pass except 5 failures that
already exist on main (cron silent-delivery + alias quick-command).
