Stability Summary

T3X is in restricted alpha. The release-facing contract is intentionally narrow while the core product and package boundaries harden.

Current Release Surface​

The restricted alpha release surface is:

  • @t3x-dev/local
  • @t3x-dev/yops

The source of truth is RELEASE.md and release/surface.yaml in t3x-core. Other packages remain internal or preview until explicitly promoted.

What Alpha Means​

  • External use is expected, and package availability follows the current release status.
  • Breaking changes are allowed when they are intentional, reviewed, and documented.
  • User-visible package changes require a changeset.
  • Public behavior should have tests, smoke checks, or conformance coverage appropriate to the risk.

YOps Contract​

YOps is part of the restricted alpha surface. Its runtime source of truth is packages/yops/yops.yaml.

Contract-bearing YOps changes include operation names, operation families, fields, field types, enum values, path syntax, runtime error codes, validator diagnostic codes, conformance cases, recipes, and examples.

See Stability Policy for the full policy, including the gate for future YOps spec-tightening PRs.

Preview And Internal Surfaces​

CLI, MCP, API, runner, storage, and other workspace packages are available for source development and preview integration work. Their external contracts may change before promotion.
