# TASK-093-03-02: Tests and Docs Pagination Rollout for Component and Data Listings

**Parent:** [TASK-093-03](./TASK-093-03_Pagination_Rollout_for_Component_and_Data_Listings.md)  
**Status:** ✅ Done  
**Priority:** 🟡 Medium  
**Depends On:** [TASK-093-03-01](./TASK-093-03-01_Core_Pagination_Rollout_Component_Data.md)

---

## Objective

Add tests and documentation updates for **Pagination Rollout for Component and Data Listings**.

---

## Repository Touchpoints

- `tests/unit/`
- `_docs/`

---

## Planned Work

### Regression Scenarios (Required)

1. component pagination happy path: paginated MCP list endpoints return correct cursor progression.
2. payload pagination happy path: large data contracts return stable page envelopes.
3. boundary path: component pagination and payload pagination do not interfere.
4. regression path: non-paginated clients still receive complete data via convenience paths.

### Metrics To Capture

- cursor progression correctness rate
- page envelope schema validation pass rate
- payload size reduction per page vs unpaginated baseline

### 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.
