-**Stability tier: PUBLIC CONTRACT.** Handover 1 is the *only* public integration boundary of the pipeline: `brief.md` is what an upstream producer hands to Voyage, and Voyage consumes it without any knowledge of who produced it. This asymmetry is a hard invariant (see `CLAUDE.md` §Trinity context) — the interactive `/trekbrief` interview is just one producer; a `manual` brief, or an external per-app / per-portfolio producer, is equally valid as long as the artifact conforms to the schema below. No producer is privileged. The consequence: changing this schema — renaming or removing a field, narrowing an enum, or promoting an optional field to required — is a **breaking change for every downstream consumer** and MUST follow the [breaking-change protocol](#breaking-change-protocol) (version bump + N-1 compatibility window). Additive *optional* fields are non-breaking by design: the validator tolerates unknown frontmatter keys silently (forward-compat), so a newer brief still validates against an older consumer. The v5.4 contract formalization froze `brief_version` **2.1** as the public-contract baseline; **v5.5 evolves it to `2.2`** under the breaking-change protocol — adding the required `framing` field + `## TL;DR` section gated at ≥ 2.2 (existing 2.0/2.1 briefs stay valid). See the Versioning paragraph below for the 2.2 details.

 **v5.5 → `2.2` (framing enforcement).** `2.2` adds two **required-at-2.2** elements — the `framing` enum field and the `## TL;DR` body section — gated identically to the v2.1 mechanism: the new requirements fire only on `brief_version ≥ 2.2`, so every existing `2.0` / `2.1` brief still validates (forward- and backward-compatible). Because adding required elements is a breaking change for any producer that declares `2.2`, this is a controlled version bump under the breaking-change protocol: downstream producers (e.g. a Tier-2 per-app producer) that emit `brief_version: "2.2"` MUST also emit `framing` + `## TL;DR`. The framing enum is additionally enforced on *any* version when the field is present (`BRIEF_INVALID_FRAMING`). The three framing-alignment layers (framing field, `brief-reviewer` memory-alignment dimension, obligatory TL;DR) implement the `CLAUDE.md` cross-cutting invariant. Note: the *plugin* version bump + CHANGELOG entry for this schema change land at the coordinated release (matrix §S10), separate from this schema axis.
