New STEP 10b (letter-suffix, no renumber): capture the greenfield's founding
decisions (stack choice + why, doctrinal exclusions, conventions) as BDRs before
STEP 11 FINISH, via lib/capitalize-commit.md. F5 filter table distinguishes
founding decision (capitalize) from scaffold detail (skip). Two explicit rules:
- No decision → no entry: trivial projects fabricate nothing; the helper no-ops.
- Founding decisions carry NO commit hash (path+date) by nature — they precede the
code, so anchoring to the scaffold commit would be a false anchor that dilutes
the meaning of hash-anchoring elsewhere. Second case where anchoring does not
apply, after a squash-merged PR.
