# Completed Plan Accomplishments (Example)

This file summarizes one fully completed execution plan produced with the step-test-update loop.

## Summary

- Plan goal: converge duplicate/redundant designs in `litellm-rs` while keeping main flows usable.
- Total steps: 39
- Step status result: all `completed`
- Phase coverage:
  - Phase A: Provider architecture convergence (A1-A4)
  - Phase B: Context/message model convergence (B1-B3)
  - Phase C: HTTP/config convergence (C1-C2)
  - Phase D: storage/cache/logging/dead-code cleanup (D1-D4)
  - Phase E: test convergence and failing-case alignment (E1-E2)
  - Phase F: large-scale provider/code redundancy cleanup (F1-F24)

## What Was Done

### Phase A (Provider convergence)

- Added consistency guard tests for provider variants and factory branches.
- Replaced placeholder `create_provider` behavior with real unified creation path.
- Removed unconnected `providers/context` module.
- Centralized "factory-supported provider types" declaration to reduce drift.

### Phase B (Context and message convergence)

- Unified request context to `core/types/context::RequestContext`.
- Removed route-layer conversion boilerplate by centralizing conversion implementations.
- Reduced parallel OpenAI message definitions and concentrated adapters.

### Phase C (HTTP and config convergence)

- Built single HTTP client builder/factory path and redirected scattered builders.
- Clarified config boundaries:
  - server runtime canonical models in `config/models`
  - SDK client canonical models in `sdk/config`
  - `core/types/config` reduced to legacy compatibility role

### Phase D (Storage/cache/logging/dead-code)

- Marked `redis_optimized` as feature-gated experimental path.
- Continued cache boundary cleanup and logging type convergence.
- Reduced legacy/dead-code exposure and cleanup noise.

### Phase E (Test convergence)

- Fixed/realigned config-related failing tests with current validation rules.
- Re-ran targeted and broader checks to confirm no new regressions for changed scope.

### Phase F (Redundant code cleanup at scale)

- Removed many unused provider-local helper methods and fields.
- Removed repeated unused `build_headers` and unused `base_client`-style state from multiple providers.
- Cleaned unused helper definitions in capability/traits/shared/security/streaming/webhook areas.
- Removed isolated/legacy duplicate paths in some provider integrations.
- Per step, ran targeted provider/module tests and `cargo check --lib`.

## Reuse Guidance

When adapting this pattern to another repo:

1. Keep phase structure but replace domain-specific steps.
2. Keep strict status transitions (`pending` -> `in_progress` -> `completed`/`blocked`).
3. Require per-step command evidence in plan logs.
4. End with final matrix checks and explicit residual risks.
