adapters lists a transcript reader that disembark packs from; embark says no source tier reads a transcript store

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

• End A: .abcd/development/brief/05-internals/02-adapters.md:350 — "Reads the root-SHA-keyed local corpus; merge by timestamp/content hash when an imported specstory source is also present"
• End B: .abcd/development/brief/04-surfaces/03-embark.md:177 — "No source tier this build packs reads a transcript store"

The adapters chapter says disembark reads into the lifeboat through source readers, including a transcript reader over the root-SHA-keyed local corpus. The embark chapter says no source tier this build packs reads a transcript store, which is why every pack declares the pass B exemption. If the transcript reader existed, that exemption would be false.
