When feeding brainstorming sessions into the PRD workflow, soft/qualitative
ideas (tone, personality, interaction design, coaching philosophy) get
silently dropped because they don't map cleanly to the PRD's structured
template (FR/NFR format). The resulting PRD reads as complete, so the
loss is invisible without manually diffing against the brainstorming output.
Add a reconciliation check in step-11 (polish) that cross-references the
brainstorming document against the finished PRD, flags ideas that didn't
land anywhere, and lets the user decide which to incorporate.
