Development record

The brief's 00-meta.md states as current fact that /abcd:embark reads a lifeboat and writes a new repo's brief by walking the brief-lifeboat mapping in reverse, with the amended press release becoming the new repo's initial brief. Shipped embark does no such thing: internal/core/lifeboat/embark_types.go classes every brief/** file of a lifeboat as report-only (IgnoredReportOnly, reportOnlyPrefixes), never written into a target. The reverse walk is a design target, so the sentence is a staged claim written in the present tense, and it misled a session into telling the product thinker that every managed repository's brief is written from the lifeboat's shape.
