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.

The request-level tenant guard compared the raw user string exactly
(user == PRODUCTION_TENANT), but all local namespaces (Qdrant
collections, Redis keys) are derived through sanitize_user_id(), which
lowercases and strips/maps punctuation. Case or punctuation variants
("JPMSchweitzer", "jpmschweitzer.", " jpmschweitzer") therefore passed
the guard yet resolved to the production namespaces, letting a dev
instance on the shared services read/write production tenant data.
- context.py: compare sanitize_user_id(user) against the sanitized
production tenant; expose the guard as public apply_tenant_guard()
- config.py: startup refusal validator uses the same sanitized
comparison, so a colliding DEFAULT_USER refuses startup loudly
instead of relying on the allowlist fallback
- tests: variant matrix at both config and request-context level,
plus a non-colliding passthrough case

Non-production environments (development/testing) now force the
effective tenant to the reserved test tenant "llm_tester" (or a
test_-prefixed override) regardless of DEFAULT_USER misconfiguration:
- Config.effective_default_user only honors DEFAULT_USER outside
production when it is llm_tester or test_-prefixed; anything else
is forced to llm_tester (tenant_forced flags the override)
- Config refuses startup (validation error) when a non-production
environment is explicitly configured with the production tenant
jpmschweitzer
- get_user() applies the same guard at request-context resolution,
so an explicit request for the production tenant in dev/test is
forced to llm_tester with a warning log
- initialize_application() emits one loud startup log line
(tenant_guard_active / tenant_guard_production) stating the
effective tenant
Unit tests cover the dev/test/prod x default/explicit-user matrix.

### 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
