# TASK-083-04-02: Tests and Docs Transform Pipeline Baseline

**Parent:** [TASK-083-04](./TASK-083-04_Transform_Pipeline_Baseline.md)  
**Status:** ✅ Done  
**Priority:** 🔴 High  
**Depends On:** [TASK-083-04-01](./TASK-083-04-01_Core_Transform_Pipeline_Baseline.md)

---

## Objective

Add tests and documentation updates for **Transform Pipeline Baseline**.

## Current State

The deterministic transform order is implemented and tested at the scaffold level.

This slice is now closed. The fuller scenarios now exist against real versioning, prompt bridge, discovery, and visibility stages.

---

## Repository Touchpoints

- `_docs/_ROUTER/RESPONSIBILITY_BOUNDARIES.md`
- `tests/unit/`

---

## Planned Work

### Regression Scenarios (Required)

1. transform order happy path: configured transform chain matches expected deterministic order.
2. name-routing path: transformed public names still resolve to canonical internal tools.
3. visibility/search interplay path: listing reflects visibility before discovery transforms.
4. regression path: provider-level vs server-level transform layering remains stable.

### Metrics To Capture

- transform-order snapshot drift count (target: 0)
- public->internal lookup mismatch count (target: 0)
- profile transform-chain coverage in tests

### Documentation Deliverables

- update task-linked docs with a before/after summary tied to the captured metrics
- document exact test commands, fixtures, and profile/config used during validation
- record compatibility or migration notes when behavior differs between surfaces

---

## Acceptance Criteria

- all required regression scenarios are implemented and passing in CI/local test runs
- metrics are captured with baseline vs post-change values and attached to the task update
- docs include the regression matrix and explain expected behavior boundaries
- no untracked regressions are observed on related router/dispatcher/platform paths

---

## Atomic Work Items

1. Implement the required regression scenarios in focused unit/integration tests.
2. Run the target suites, collect metric outputs, and compare to baseline values.
3. Update docs with regression matrix, metric table, and migration/compatibility notes.
4. Verify adjacent surfaces for spillover regressions and document the result.
