plan.rs

1//! Public wire DTO for the sealed, content-addressed release plan
2//! (`ossctl release plan` — ADR-0002 §3).
3//!
4//! A [`ReleasePlan`] is the read-only pre-image a human approves: the ordered
5//! concrete target set a cut would publish, the invariant phase sequence the
6//! coordinator will drive, the git `HEAD` it was sealed against, the chosen
7//! release version, and the content-addressed [`ReleasePlan::plan_id`]. `release
8//! cut --plan <plan_id>` re-derives the plan from *current* repo state and
9//! refuses (`plan_stale`) if the id no longer matches — so a commit, a manifest
10//! rename, a schema bump, or a different chosen version between approval and
11//! execution aborts rather than silently publishing something else.
12//!
13//! Consumers read this document under the CLI's canonical `data` envelope:
14//! `{schema_version, data: <this shape>, warnings}` — the same envelope every
15//! `ossctl --json` command shares (`crate::SCHEMA_VERSION` versions that wire
16//! envelope). Like `facts` and `audit`, the plan is *derived*, never authored,
17//! so it has no document version of its own; the envelope's `schema_version` is
18//! the wire version consumers gate on. [`ReleasePlan::contract_schema_version`]
19//! is a *content* field (the contract-document version the plan was sealed
20//! against, part of the content address), not the wire-envelope version.
21//!
22//! The plan **reuses** [`Ecosystem`], [`Registry`], and [`Adapter`] from the
23//! canonical contract model rather than restating their wire strings: the plan,
24//! the contract, and the release adapters must agree on `"rust"` /
25//! `"crates.io"` / `"cargo-publish"` down to the byte, and sharing the one enum
26//! makes that agreement structural instead of coincidental.
