Live e2e revealed M2 never translated the static catalog strings: the model
returns the batch-translate mapping wrapped under a "strings" key (echoing the
request envelope) — {"strings": {src: translation}} — so _fill_cache's
top-level table.get(src) missed every source and cached the English original.
Unwrap one level when the sources aren't top-level keys, and tighten the prompt
to ask for a flat object. The unit-test fake now mirrors the real wrapped shape
so this can't regress (a flat fake hid the bug).

Follow-up to the reply-language feature. The update_model action commits its
"Model changed to <name>" notice directly via compare_and_advance, bypassing
Runner._commit and thus the Env.localize_items hook, so that one notice stayed
English. Localize it in the service (when the session has a detected
reply_language) with a "Model changed to {name}" catalog template that
translates the frame and re-inserts the model name verbatim.

Follow-up to the reply-language feature. `_model_or_none` was private to
LlmBuilderAgent, so the advance-task wiring reached it via a fragile
`getattr(agent, "_model_or_none", lambda: None)`. Make it part of the
DifyBuilderAgent protocol (typed `object | None` to keep the pure port free of
any model-runtime import) and implement it on every conforming agent
(LlmBuilderAgent renames the private method public; PlaceholderAgent and the
test doubles return None). The Localizer wiring now uses `agent.model_or_none`
directly. Also drops the useless-return ruff nit in the wiring test.

Final-review fix wave for the "reply in the user's input language" feature:
- serde.py: context_from_dict omitted reply_language from the explicit field
allowlist, so it round-tripped to "" on every read despite context_to_dict
(asdict) serializing it -- the localization feature silently no-op'd after
the first persisted write. Added it to the constructor call; TDD'd with a
failing-then-passing round-trip test in test_serde.py.
- localize.py: Localizer._cache was per-instance, but a fresh Localizer is
built per advance-task invocation, so the static string catalog was
re-translated every turn instead of once per language. Moved the cache to a
module-level _TRANSLATION_CACHE dict (safe to share: keys are
tenant/session-independent catalog-string+language pairs); added an autouse
fixture in test_localize.py to clear it between tests for isolation.
- localize.py: detect_language and _fill_cache called self._model_provider()
outside their try/except, violating the Env callback contract that these
must never raise. Moved both calls inside their try/except so a raising
provider degrades to the existing safe fallback instead of propagating into
advance/_commit.
- strings.py: documented that Template.translate_fields is advisory only --
the Localizer re-inserts all captured groups verbatim and does not consult
it. No behavior change.
uv run --project api pytest tests/unit_tests/core/dify_builder tests/unit_tests/services/dify_builder -q
-> 722 passed.

The build/edit test handlers wrapped run_draft in a bare, non-logging
`except Exception` that turned any launch-time failure into a blank failed
run (dify_run_id="", per_node=[], no error). Diagnose then had nothing to
act on and the repair loop ran blind — the prod symptom where a stale test
input (ValueError "<var> is required in input form") produced an
undiagnosable await_repair loop.
Now the launch error is logged, captured, and persisted so diagnose/routing
can act on it:
- Run.error field + dify_builder_runs.error column (migration a9cc8d552db4)
- handlers_build/edit: logger.exception + launch_error_text(exc) -> Run.error
- is_input_failure() also inspects Run.error (+ "in input form" signal), so a
stale-input launch failure routes to the testdata gate, not blind repair
- diagnose/_degraded_diagnosis surface the launch error when no node executed
