feat(test): Phase 1.5 coverage expansion - COV-001 to COV-013
Coverage baseline raised from 13.65% to 26% (+12.35%) Gate raised from 12% to 18% Tasks completed: - COV-001: Command system unit tests (100% coverage) - COV-002: API service unit tests batch 1 (user/apikey/model/provider) - COV-003: Provider model manager unit tests - COV-004: Pipeline remaining stage tests (aggregator/cntfilter/longtext/msgtrun) - COV-005: Storage and utils coverage pass - COV-006: Gate ratchet 12%→15% - COV-007: Gate ratchet 15%→18% - COV-008: API service batch 2 (bot/pipeline/webhook/space/maintenance/mcp) - COV-009: Blocked - API controller circular import issue documented - COV-010: Plugin runtime unit tests (+0.08%) - COV-011: RAG and vector unit tests (+0.68%) - COV-012: Core boot and migration unit tests - COV-013: Provider requester logic unit tests (+0.62%) Key additions: - tests/utils/import_isolation.py: sys.modules isolation for circular imports - Provider requester mock tests: proved HTTP-dependent code can be tested locally - Vector filter utilities: 100% coverage on pure functions - API services: fake persistence pattern for unit testing Blocked issue COV-009 documented in langbot-test-plan/1.5/issues/ Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
