itd-11 hardens an existing chat-distiller; disembark says the transcript-reading distiller is not built and waits on itd-11

A sequencing impossibility (severity minor) found by the cross-document consistency pass.

• End A: .abcd/development/intents/drafts/itd-11-pass-b-pitfall-mitigation.md:36 — "Replacing chat-distiller with an entirely different approach (this is hardening, not redesign)"
• End B: .abcd/development/brief/04-surfaces/02-disembark.md:114 — "Not built yet: routing such disagreements to a transcript-reading distiller that emits a finding for the unrecorded-decisions report. Viability is gated on itd-11 (draft)"

itd-11 is scoped as hardening a chat-distiller that already reads transcripts, and it rules out a redesign. The disembark chapter says that distiller is not built yet and that whether it is viable waits on itd-11. Each document waits on the other: the draft assumes the distiller exists, and the surface holds off building it until the draft lands.
