Two compression-tip hydration tests simulated legacy state by emptying
the parent AFTER end_session(compression) — exactly the durable write
the new closed-parent guard refuses. Reordered: empty first, close
second. The tests' actual contract (old id hydrates from the live tip)
is unchanged and still pinned.
Add a persisted, backend-confirmed provider/model lock for Hermes
Browser and other session API clients. A confirmed lock is an
execution contract rather than response metadata:
- POST /api/sessions/{session_id}/model validates and persists a
confirmed browser_model_lock (advertised in /v1/capabilities)
- session chat + chat/stream consume the persisted lock on body-only
follow-up turns; a confirmed lock wins over an older gateway session
/model override and the session-persisted model
- a later successful session /model switch explicitly clears and
replaces the lock while preserving lineage markers (_branched_from)
and invalidating cached system-prompt model/provider metadata
- ordinary one-off request overrides never replace a confirmed lock
- provider-resolution failure fails closed as a typed provider-auth
error (controlled response, never global-credential reuse)
- confirmed locks disable the global fallback model chain
- the completed agent's actual provider/model must match the locked
route or the turn fails with a runtime-mismatch error
- responses carry sanitized runtime metadata reporting actual vs
requested provider/model and lock state
Rebased onto the provider-aware request routing (#70853) and
session-model parity (#70931) that landed since the original branch;
the lock now slots into that precedence chain as the top rung.

Three parity fixes between the API server and the native gateway's
agent-runtime resolution, integrated with the provider-aware request
routing that landed in #70853:
- Session-persisted model is honored: POST /api/sessions {"model": ...}
stores a model that the chat handlers previously fetched and threw
away. A stored value that matches a model_routes alias goes through
the route path (route provider/credentials apply); a raw model string
threads through as session_model, pinning the session's turns ahead
of per-request body values but below an explicit session /model
override.
- Empty-model recovery: provider-catalog default when config has no
model.default but a provider resolved, plus last-known-good model
recovery (#35314) keyed on gateway_session_key only (never ephemeral
session_id — no unbounded growth from one-off requests).
- Provider auth failures surface as controlled responses: RuntimeError
from _resolve_runtime_agent_kwargs() is re-raised as a dedicated
_ProviderAuthResolutionError at the call site, caught narrowly in
_run_agent() and the /v1/runs executor to return run.py's response
shape instead of an undifferentiated 500 (session-chat endpoints
previously returned a raw aiohttp 500 with no JSON body).

The api_server adapter returned error code "invalid_api_key" for
API_SERVER_KEY authentication failures, which the Desktop error
classifier misidentified as a provider (OpenRouter/OpenAI) key
problem — showing "OpenRouter API key missing" when the real issue
was gateway auth.
Changes:
- gateway/platforms/api_server.py: return "gateway_auth_failed" code
with descriptive message for API_SERVER_KEY auth failures
- apps/desktop/src/store/notifications.ts: add "gateway_auth_failed"
handler before "invalid_api_key" to show correct error message
- agent/error_classifier.py: add "gateway_auth_failed" to auth patterns
- tests: update test_session_api.py to expect new error code

* docs(code-execution): document HERMES_* env narrowing + passthrough workaround
The execute_code sandbox-child env scrub (108397726, #27303) deliberately
dropped the broad HERMES_ prefix passthrough, keeping only an operational
4-var allowlist (HERMES_HOME/PROFILE/CONFIG/ENV). A script that relied on a
non-secret HERMES_* var (HERMES_BASE_URL, HERMES_KANBAN_DB, HERMES_*_WEBHOOK,
or a plugin-defined one) now sees it unset in the child.
Document the behavior change and the two recovery routes (terminal.env_passthrough
in config.yaml, or required_environment_variables in skill frontmatter), plus
the debug log line that surfaces the drop for diagnosis.
* fix(api_server): emit per-turn transcript on run.completed (#34703)
WebUI clients lost intermediate (pre-tool-call) assistant text after
switching session pages mid-stream. The session-chat SSE stream delivers
all assistant text as assistant.delta events under one message_id
interleaved with tool.* events, then a single assistant.completed
carrying only the final reply — so a client accumulating deltas into one
buffer cannot reconstruct intermediate text segments that preceded tool
calls, and they vanish from the live view (state.db persists them
correctly).
run.completed now carries the authoritative per-turn transcript
(assistant + tool messages for this turn, in client-safe shape) so any
SSE consumer can reconcile its live view against ground truth without a
separate GET /messages round-trip. Purely additive — clients that ignore
the field are unaffected.
Remove unused imports (F401) and duplicate/shadowed import
redefinitions (F811) across the codebase using ruff's safe
autofixes. No behavioral changes -- imports only.
- ~1400 safe autofixes applied across 644 files (net -1072 lines)
- __init__.py re-exports preserved (excluded from F401 removal so
public re-export surfaces stay intact)
- Re-exports that are imported or monkeypatched by tests but look
unused in their defining module are kept with explicit # noqa:
F401 (gateway/run.py load_dotenv; run_agent re-exports from
agent.message_sanitization, agent.context_compressor,
agent.retry_utils, agent.prompt_builder, agent.process_bootstrap,
agent.codex_responses_adapter)
- Unsafe F841 (unused-variable) fixes deliberately skipped -- those
can change behavior when the RHS has side effects
- ruff lints remain disabled in pyproject.toml (only PLW1514 is
selected); this is a one-time cleanup, not a config change
Verification:
- python -m compileall: clean
- pytest --collect-only: all 27161 tests collect (zero import errors)
- core entry points import clean (run_agent, model_tools, cli,
toolsets, hermes_state, batch_runner, gateway)
- static scan: every name any test imports directly from an edited
module still resolves
#33016 added GET /v1/skills + /v1/toolsets on the API server; the
capability flag introduced in this branch was placeholder-False. Flip
to True so capability probers see the truth.
