# T81 Foundation Documentation

For the research mission, start with the [root README](../README.md), [Master Continuity Charter](research/continuity/MASTER_CONTINUITY_CHARTER_v1.0.md), and [hypothesis register](research/continuity/HYPOTHESIS_REGISTER_v1.json). The handoff and roadmap below cover supporting maintenance. The [root alignment audit](research/ROOT_DOCUMENTATION_ALIGNMENT_AUDIT.md) distinguishes current entry points from historical claims.

This directory is the canonical documentation surface below `/spec` and
`docs/architecture/OVERVIEW.md`.

## Start Here

If you only want the shortest current contributor path, read these first:

- [Maintainer Handoff](HANDOFF.md)
- [Contributor Roadmap](ROADMAP.md)
- [Buildable Next Steps](BUILDABLE_NEXT_STEPS.md)
- [T81 Operator Guide](explanation/T81_OPERATOR_GUIDE.md)

Those three files describe the current engineering posture more directly than
the broader documentation tree:

- the bounded AI OS-object family is a protected subsystem
- RFC-00D1 CanonFS interchange is the best current draft-to-code bridge
- portability, CI boringness, and contributor-path clarity are active work, not cleanup after the fact

## Canonical Entry Points

- [Architecture Overview](architecture/OVERVIEW.md)
- [Maintainer Handoff](HANDOFF.md)
- [Contributor Roadmap](ROADMAP.md)

- [Freeze Enforcement](governance/FREEZE_ENFORCEMENT.md)
- [Determinism Surface Registry](governance/DETERMINISM_SURFACE_REGISTRY.md)
- [Determinism Threat Model](governance/DETERMINISM_THREAT_MODEL.md)
- [Project Control Center](status/PROJECT_CONTROL_CENTER.md)
- [Drift Decomposition](status/DRIFT_DECOMPOSITION.md)
- [Implementation Matrix](status/IMPLEMENTATION_MATRIX.md)
- [Spec Index](../spec/README.md)
