The mental model says per-step lanes are a planned intent; that intent is on the shipped shelf and says the build lands steps one lane at a time.

The mental model says per-step lanes are a planned intent; that intent is on the shipped shelf and says the build lands steps one lane at a time.

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

• End A: .abcd/development/brief/01-product/03-mental-model.md:56 — "per-step lanes are itd-2609212103565953, planned"
• End B: .abcd/development/intents/shipped/itd-2609212103565953-a-spec-lists-its-steps-and-the-build.md:21 — "A spec lists its steps, and abcd build lands them one at a time, each its own lane and pull request."

The brief qualifies the step-per-lane model as itd-2609212103565953, planned. That record sits under intents/shipped/ and its press release states that abcd build lands the steps one at a time, each as its own lane and pull request. One of the two misstates whether per-step lanes exist.
