# Preview release policy

`v0.1.0-preview.2` may be published only after one identical candidate Tend
binary has successfully completed maintenance releases for Gamertan and the
Sandwich Hime website, including injected-failure restoration and explicit
rollback proof. The August 14, 2026 campaign met that gate; the scoped,
sanitized record is in `docs/DOGFOOD_EVIDENCE.md`.

Before a preview tag:

1. Run `./scripts/verify.sh` from a clean pushed private-development commit.
2. Review dependency, license, race, filesystem, archive, and rollback evidence.
3. Export the exact allowlisted public tree into a new root commit.
4. Verify canonical Gitea and GitHub discovery trees are byte-identical.
5. Sign the canonical Gitea tag and attach checksums and an SPDX SBOM.
6. Verify a fresh public checkout before advertising installation.

The release tag and attached candidate must be built from the final reviewed
source commit. Documentation-only changes after the recorded campaign require
one final identical-candidate maintenance pass before tagging.

`v0.1.0-preview.1` is immutable but withdrawn: its source and module checksums
are valid, while a fresh `go install` reports the development identity because
the CLI did not yet adopt the tagged module version from Go build information.
Preview 2 adds that identity path and its regression tests; preview 1 is never
retagged or rewritten.

The canonical public origin is `ssh://git@gitea.speelman.ca:2222/gamertan/tend.git`.
GitHub is a read-only discovery snapshot. Private development history is not
published or merged into either public history.
