# Documentation index

This index separates stable, current behavior from exploratory material and local release preparation.

## Stable documentation

- [Coordination model](reference/coordination-model.md) — explicit durable roles, assignments, and bounded hierarchy.
- [Operational boundaries](reference/operational-boundaries.md) — local state, authority limits, and what the extension never performs.
- [Prompt injection and context](prompt-injection.md) — additive context, precedence, and explicit delegation guidance.
- [Contributor guide](../CONTRIBUTING.md) — local development and validation.
- [Optional pi-intercom companion](pi-intercom.md) — transport relationship; `pi-intercom` is not a package dependency.
- [Release and version preparation](release-version-preparation.md) — local SemVer decisions and validation only.

## Exploratory documentation

- [Fast decision model](reference/fast-decision-model.md) — **Exploratory**; not a runtime contract or delivery promise.

See the [reference index](reference/README.md) for the stable/exploratory reference split.
