refactor: remove unshipped reflection service by yyiilluu · Pull Request #360 · ReflexioAI/reflexio

yyiilluu · 2026-07-18T06:38:42Z

Summary

Remove the unshipped, citation-driven ReflectionService in one clean change without deprecation shims.
Delete its public client/config surfaces while preserving the supported profile and playbook learning paths.
Ignore and remove the retired reflection_config key when loading legacy private local configuration.

Changes

Runtime and public API

Remove run_reflection, ReflectionConfig, reflection service wiring, deferred/durable orchestration hooks, and reflection billing/model registry entries.
Keep generation, profile extraction, playbook updates, and durable learning behavior on their supported paths.
Add durable publish-to-worker coverage for the remaining learning pipeline.

Prompts, evals, and documentation

Delete the reflection prompt family, service implementation, dedicated eval harness, fixtures, and tests.
Update scenario/consolidation evals and internal package documentation so they no longer depend on reflection.
Add regression coverage proving removed config/API symbols stay unavailable.

Test Plan

OSS unit/integration suite: 4722 passed, 73 skipped, 6 subtests passed
OSS E2E suite: 43 passed, 49 skipped
Focused removal and configuration suites: passed
Ruff lint/format and Pyright: passed
Removed-symbol repository audit: no remaining runtime/public references

Summary by CodeRabbit

New Features
- Durable learning now focuses on profile and playbook updates without a separate reflection stage.
- Legacy reflection configuration is removed from the public configuration model.
Bug Fixes
- Legacy configuration files are automatically cleaned up while preserving settings, even if cleanup is temporarily unsuccessful.
Documentation
- Updated service, attribution, lineage, and evaluation documentation to reflect the streamlined learning workflow.
Tests
- Added coverage for legacy configuration cleanup and profile/playbook persistence.

Delete the public API, config model, orchestration, prompts, evals, and service-only tests. Preserve legacy private config loading by stripping the retired raw key before strict validation.

📝 Walkthrough

Walkthrough

Reflection functionality is removed from the public facade, configuration schema, generation and durable-learning pipelines, service modules, prompt registry, and evaluation harnesses. Persisted legacy configuration cleanup, consolidation-only scenarios, lineage semantics, billing attribution, and related tests and documentation are updated.

Changes

Reflection subsystem removal

Layer / File(s)	Summary
Public contracts and configuration cleanup `reflexio/lib/`, `reflexio/models/`, `reflexio/server/services/configurator/*`	The `Reflexio` facade and `Config` schema no longer expose reflection, and legacy `reflection_config` keys are removed from local files when possible.
Runtime learning pipeline removal `reflexio/server/services/generation_service.py`, `reflexio/server/services/deferred_learning_plan.py`, `reflexio/server/services/reflection/*`, `reflexio/test_support/llm_model_registry.py`	Durable and classic learning no longer execute reflection stages, plans, persistence, side effects, or registry validation; the reflection service is deleted.
Consolidation-only evaluation flow `tests/eval/*`, `tests/models/test_removed_reflection_config.py`	Scenario and prompt-deviation evaluation paths now cover extraction and consolidation only, with reflection schemas, providers, fixtures, and tests removed.
Supporting tests, attribution, and documentation `reflexio/README.md`, `reflexio/server/README.md`, `tests/server/*`	Documentation, billing sources, lineage expectations, durable-learning tests, storage contracts, and playbook operation identifiers are updated for the remaining paths.
