Fast-lane backlog: namespace canonical policy violations (23 missing __CANONICAL__ / legacy src.* imports)

[neuron7xLab]

Surfaced by the restored fast oracle (#1153). tests/test_architecture_guards.py::test_namespace_integrity_has_no_violations (23 violations, e.g. src/geosync/risk/__init__.py missing __CANONICAL__ = True) and tests/unit/scripts/test_namespace_shims_importable.py::test_namespace_policy_gate_passes (scripts/check_namespace_policy.py main()==1: legacy src.* imports outside the curated allowlist) both fail.

Likely subsumed by the in-flight import-architecture consolidation (#1159) — cross-reference before draining to avoid duplicate work.

Drain criterion: namespace policy gate returns 0 and architecture-guards reports zero violations under the real oracle; remove both quarantine lines. Quarantined in #1153.

[neuron7xLab]

Resolved & verified. This fast-lane backlog cluster is marked drained in docs/ci/fast_backlog_ledger.md (quarantine entry removed), and its verification test now runs green on main — re-confirmed locally after #1230 restored fast-lane collection (the torch-probe DeprecationWarning fix that had zeroed the lane under Python 3.11):

$ pytest tests/test_architecture_guards.py::test_namespace_integrity_has_no_violations + namespace_shims  ->  PASS

No quarantine entry remains for this cluster; a new failure would fail python-fast-shard (now real-green, not vacuous). Closing.
