The launch chapter says the repo organises work by phase per adr-9; the mental model says the phase is retired and adr-9 superseded

A premise contradiction (severity minor) found by the cross-document consistency pass.

• End A: .abcd/development/brief/04-surfaces/04-launch.md:489 — "the repo organises work by phase (see [adr-9] (../../decisions/adrs/0009-phase-as-product-layer.md)), and a release number is what falls out when a stretch of that work is published."
• End B: .abcd/development/brief/01-product/03-mental-model.md:56 — "The phase and the milestone are retired"

The launch chapter's versioning section says the repo organises work by phase, citing adr-9, and that a release number falls out when a stretch of that work is published. The mental model says the phase and the milestone are retired, and its opening paragraph names adr-9 as superseded. The launch chapter's account of what a version measures rests on a unit the record no longer has.
