# BinaryIndex Persistence Tests Charter

## Mission
Validate BinaryIndex persistence behavior with deterministic integration tests.

## Responsibilities
- Maintain `StellaOps.BinaryIndex.Persistence.Tests`.
- Keep tests deterministic and offline-friendly with controlled fixtures.
- Surface open work on `TASKS.md`; update statuses (TODO/DOING/DONE/BLOCKED/REVIEW).

## Key Paths
- `BinaryIndexIntegrationFixture.cs`
- `BinaryIdentityRepositoryTests.cs`
- `CorpusSnapshotRepositoryTests.cs`

## Coordination
- Persistence and Infrastructure.Postgres teams.

## Required Reading
- `docs/modules/binaryindex/architecture.md`
- `docs/modules/platform/architecture-overview.md`

## Working Agreement
- 1. Update task status to `DOING`/`DONE` in both corresponding sprint file `/docs/implplan/SPRINT_*.md` and the local `TASKS.md` when you start or finish work.
- 2. Review this charter and the Required Reading documents before coding; confirm prerequisites are met.
- 3. Keep changes deterministic (stable ordering, timestamps, hashes) and align with offline/air-gap expectations.
- 4. Coordinate doc updates, tests, and cross-guild communication whenever contracts or workflows change.
- 5. Revert to `TODO` if you pause the task without shipping changes; leave notes in commit/PR descriptions for context.
