The 21 the automatic pass could not make on its own. `ruff check` and
`ruff format --check` are both clean now; typecheck is still red and is next.
`in_reasoning` in chat/service.py was a complete state machine that nothing read:
initialised False, set True when a reasoning delta arrived, set False when the
summary ended — three assignments, zero reads. Ruff reported one at a time, and
removing each revealed the next, so what looked like a single stray variable took
three passes to bottom out. The branches themselves do real work and are
untouched; only the flag is gone.
Four `raise HTTPException` inside `except` blocks now chain with `from e`. Until
now a failure while handling an error was indistinguishable from the error, which
matters most in exactly the situation where the traceback is all you have.
In biographer/tools.py the binding was unused but the call is not: MemoryType()
is called for the ValueError it raises on an invalid name. The binding is gone
and the call and its comment stay, because dropping the line would have removed
the validation.
The rest are unused bindings in tests where the assertions are on something else
(call_args, mostly), plus three unused loop variables and an isinstance tuple.
One correction to my own work: removing a dead comprehension in
test_error_handling.py left an `if` block with nothing but comments in it, which
is a SyntaxError. Ruff caught it immediately. The block now says what the test
actually pins — that the stream parses without crashing, which reaching that line
demonstrates — rather than computing a list nobody asserts on.
`make test` is intermittent here, and it is not this change.
test_tatlock_tool_call_logging_calculator failed in two of five full runs across
both HEAD and this branch, and passes in the other three; it also fails in
isolation at HEAD while passing in isolation here. Order- or timing-dependent.
Recorded rather than chased, since tests are not gated in this repo yet.

Mechanical only, and separated from the judgment calls that follow so the
reviewable changes are not buried in a 98-file whitespace diff.
227 automatic fixes: 60 blank lines carrying whitespace, 60 unsorted import
blocks, 34 Optional[X] to X | None, 28 unused imports, 16 deprecated typing
imports, 12 datetime.timezone.utc to datetime.UTC, and assorted smaller
modernisations. Then `ruff format` over src and tests: 98 files reformatted,
35 already conforming.
No file among the unused-import findings defines __all__ or is an __init__.py,
so nothing here removes a re-export.
`make test`: 658 passed, unchanged from HEAD.
Two things observed while verifying, neither addressed here:
`pytest tests/` cannot collect — tests/e2e/test_orchestration_e2e.py uses an
`e2e` marker that is not registered, and the config is strict about markers.
This fails identically at HEAD, so it predates this change; `make test` passes
because it ignores tests/e2e, tests/integration and tests/contracts.
test_tatlock_tool_call_logging_calculator is flaky. It failed once in a full run
with these changes and passed on the next, passes in isolation with them, and
fails in isolation at HEAD. It is order- or timing-dependent, not a regression
from this commit — established by running the full suite both ways rather than
by reasoning about which change could have caused it.

### Added
- Environment-aware configuration:
- Auto-selected logging (DEBUG for dev, WARNING for prod)
- Auto-selected default user (llm_tester for dev isolation)
- User context logging at request entry
- Direct delegation bypass:
- Pure memory/librarian requests skip Tatlock LLM
- Reduces latency for memory-only requests
- Text-based delegation fallback:
- Parse [DELEGATE:agent] patterns from LLM output
- Sequential and parallel execution support
- Comprehensive E2E test suite:
- 22 orchestration tests with QdrantVerifier
- assert_llm_behavior() for flexible pattern matching
- Tests for memory, delegation, isolation, scenarios
### Fixed
- Unit test mocks for streaming (async generator)
- Temporal context handling in tests
- LLM non-determinism with pytest.xfail()
- Streaming test timeouts increased
