# Method
A release convention with one technology-agnostic spine and a small, named surface where technologies differ. A project adopts the spine as-is, then takes the binding for its technology.
Start with [the model](./00-model.md), hold [the invariants](./01-invariants.md), then follow the chapter for the work at hand: [setup](./02-setup.md) once per repository, [operate](./03-operate.md) for every release, [recovery](./04-recovery.md) when one goes wrong. [The diff surface](./05-diff-surface.md) is where the bindings plug in, and the two walkthroughs — [release from trunk](./06-release-from-trunk.md), [branch for release](./07-branch-for-release.md) — show each release style end to end.
| [00 — Model](./00-model.md) | The spine, the branch forms, the one-pull-request gate |
| [01 — Invariants](./01-invariants.md) | What never varies, in any technology |
| [02 — Setup](./02-setup.md) | Bootstrapping a repository onto the convention, in order |
| [03 — Operate](./03-operate.md) | Cutting a release, end to end |
| [04 — Recovery](./04-recovery.md) | Withdrawing, unsticking, and hand-publishing |
| [05 — Diff surface](./05-diff-surface.md) | The four axes a binding declares |
| [06 — Release from trunk](./06-release-from-trunk.md) | The default style, walked through one release and one fix |
| [07 — Branch for release](./07-branch-for-release.md) | The whole life of an older line, cut to deletion |
Per-technology bindings live under [bindings](../bindings/README.md). The deterministic files a binding lands come from `rk init`; the pinned tool versions they assume are declared once, in the versions registry, readable with `rk versions`.
