Accept BC, SA, PP and MIL-001 after review

Review BC-001, SA-001, PP-001 and MIL-001 and record the results as
RC-001 to RC-004. All four verdicts are Go, so their Version History
rows become Accepted and the previous rows Deprecated. MIL-002 to
MIL-004 stay Proposed.

BC-001 failed criterion 1 (cost-benefit not justified as qualitative).
Add the justification and a target-completion constraint (2026-10-14)
that PP-001 and MIL-001 are checked against.

Add the Traceability Matrix (TM-001) and register RC and TM in the
artifact registry. PP has no QC checklist, so RC-003 checks the plan
against BC-001 and the milestones instead. Author and reviewer are
both S01, a deviation noted in each record.

+| # | Criterion | Status | Evidence/Notes |
+| --- | --- | --- | --- |
+| 1 | ROI/Cost-Benefit analysis is quantitative, or where qualitative, is explicitly justified | Pass | Qualitative; justification paragraph added under Cost–Benefit Assessment (personal project, no revenue or budget). |
+| 2 | Risks are identified with documented impact and mitigation | Pass | Three risks, each with impact and mitigation. |
+| 3 | Success criteria are measurable, stating explicit targets | Pass | Five criteria with target and measure. |
+| 4 | Scope explicitly separates In Scope vs Out of Scope | Pass | Separate subsections. |
+| 5 | Stakeholders are cross-referenced to Stakeholder Analysis IDs | Pass | S01–S03 used; the table only states interest. |
+| 6 | Methodology and quality-standard foundation are stated explicitly (Optional) | Pass | SQA/QC framework and ISO/IEC 25010:2023 named. |
+| 7 | Assumptions and constraints are explicit and distinguished | Pass | Separate sections; target date added to Constraints. |
+| 8 | Document supports executive decision-making with a clear recommendation | Pass | Recommendation: Proceed, with rationale. |
+
+## Overall Verdict
+
+Go — all mandatory and optional criteria pass. Reviewer and author are both S01: the project has a single participant, so the framework's author/reviewer separation cannot be met. S01 accepted this deviation when requesting acceptance (2026-10-04).
