Add SPEC-017/018/019 and the amendments they force Three features specified: wallet balancing, buy/sell opportunity, wallet goals. 80 business rules, 52 acceptance criteria, 24 logged decisions. None of them is additive-only, so the reversals are recorded where the original decision lives rather than left to contradict it silently: PRD Q6 answered yes after being open since the PRD was written SPEC-015 target allocation removed from Out of Scope; DL-015-03 superseded in part -- the advice risk is mitigated by requiring every threshold to originate with the user, not by omitting the feature. BR-015-06 stands. SPEC-010 BR-010-02 promoted from descriptive to calculated SPEC-004 consent basis extended to opportunity and goal email SPEC-002 four config keys added SPEC-008 unchanged -- rules are held-assets-only, so DL-008-06 and the quote ceiling stand untouched PRD gains F7 (FR-7.x), F8 (FR-9.x) and F9 (FR-10.x), milestone M7, and three traceability rows. FR-8.x is skipped deliberately: section 8 owns that range and renumbering it would invalidate citations in four specs. Coverage check: 256 requirements, 0 uncovered. Template compliance: 19/19 specs at 5/5 sections.
