# 30-Nov-2025 · Ecosystem Reality Test Cases for StellaOps

**Why now:** Real incidents (credential leak, offline DB schema mismatch, SBOM parity drift, scanner instability) must translate into deterministic acceptance tests.

## Scope
- Document the five incidents and expected signals.
- Map each to acceptance tests and fixture paths (`tests/fixtures/sca/catalogue/`).
- Drives ECOSYS-FIXTURES-GAPS-300-017 (ET1–ET10).

## Required artefacts (MVP)
- This advisory plus fixture root path and acceptance test references.
- Sprint tracker row 21 updated when evidence lands.

## Determinism & Offline
- Fixtures must pin tool versions and feeds; no live network.

## Next actions
- Populate fixtures and acceptance specs; log in sprint Execution Log when added.
