The Strix proxy / ``strix/`` model namespace is gone. Users now pass
real provider aliases directly (``anthropic/claude-sonnet-4-6``,
``openai/gpt-5.4``, ``gemini/...``, ``openrouter/...``).
Deleted:
- ``STRIX_API_BASE`` constant in ``strix/config/config.py`` (and the
auto-set api_base branch for ``strix/`` models in ``resolve_llm_config``).
- ``STRIX_MODEL_MAP`` and the ``StrixModelProvider`` /
``LitellmAnthropicProvider`` classes from
``strix/llm/multi_provider_setup.py``.
- ``is_anthropic_override`` flag on ``AnthropicCachingLitellmModel``
(only existed because ``strix/<alias>`` resolved to ``openai/<base>``
on the wire while staying Anthropic underneath; with no proxy, the
model-name substring check is enough).
- ``startswith("strix/")`` branches in ``cli.py`` / ``main.py`` /
``dedupe.py`` and the ``uses_strix_models`` env-validation flag.
The new ``build_multi_provider`` registers a single ``anthropic/``
route that wraps litellm in :class:`AnthropicCachingLitellmModel`
(prompt caching). Every other prefix falls through to the SDK's
built-in routing.
Defaults flipped from ``strix/claude-sonnet-4.6`` →
``anthropic/claude-sonnet-4-6`` in run_config_factory and
agents_graph/tools.py + corresponding tests.
Tests updated:
- ``test_anthropic_cache_wrapper.py``: drop the override-flag tests.
- ``test_multi_provider_setup.py``: rewrite around the new single
``_AnthropicCachingProvider`` route.
- ``test_tool_registration_modes.py::test_load_skill_import_...``:
load_skill no longer fails when there's no live agent instance — it
echoes the requested skills back with ``success=True``.
Tests: 281/281 passing.

Three foundation modules per PLAYBOOK §2.8 / §2.9 / §2.10 with all
relevant R2/R3 corrections (C7, C10, C11, C16, C21):
strix/llm/strix_session.py SessionABC wrapper around the
legacy MemoryCompressor; on any
compression failure, returns
uncompressed history and
permanently disables compression
for the rest of the run (C10 +
Round 3.4 W5/E2).
strix/telemetry/strix_processor.py SDK TracingProcessor that writes
events.jsonl in our schema. All
hooks SYNC per ABC (F3); writes
protected by per-path
threading.Lock (C7); OSError
swallowed and logged (C16); PII
scrubbed via the existing
TelemetrySanitizer.
strix/run_config_factory.py make_run_config() with our
defaults: parallel_tool_calls=
False (C1 Phase-1 safe default),
retry policy explicitly excludes
401/403/400 (C11), reasoning
effort + model_settings_override
merge path (C21).
make_agent_context() returns the
canonical per-agent dict
including is_whitebox/diff_scope/
run_id (C21).
32 new smoke tests (197/197 total). mypy strict + ruff clean. Per-file
ignores added for tests/** S105/PT018 and for the two new src modules'
intentional broad-Exception catches (BLE001).
