## Artifact Under Review

- Instance reviewed: [BC-001]
- Checklist used: [QC-BC-001]
- Scope: delta re-review of criteria 2, 3, 4 and 7 (the change adds objective O6, an In Scope bullet, an assumption, a constraint and success criterion 6); criteria 1, 5, 6 and 8 are re-read and unchanged. Earlier record: [RC-067]
- Language and domain: n/a for this delta (the action item of [RC-067] about the Language and Domain rows is still open)
- Language reviewer: none
- Mode: supervised, not independent (the author, Jens Tirsvad Nielsen, asked in chat on 2026-10-19 for the acceptance and stands in for S01; the AI prepared the evidence)

## Checklist Results

| # | Criterion | Status | Evidence/Notes |
| --- | --- | --- | --- |
| 1 | ROI/Cost-Benefit analysis is quantitative, or where qualitative, is explicitly justified | Pass | Unchanged; the Cost-Benefit Assessment labels its qualitative form. |
| 2 | Risks are identified with documented impact and mitigation | Pass | The delivery risk of the VPN actions (the runner cannot give the privileges, or the daemon does not survive between steps) is a plan risk in PP-001 with a mitigation; the Business Case risks about secrets already cover a leaked key. |
| 3 | Success criteria are measurable, stating explicit targets rather than vague aspirations | Pass | Criterion 6: "2 (WireGuard and Tailscale) by MIL-012", measured by the recorded runs of tasks 3 to 5, with no secret in the run log. |
| 4 | Scope explicitly separates In Scope vs Out of Scope | Pass | "Shared composite actions that connect a deployment job to a private network through WireGuard or Tailscale (MIL-012)" is a new In Scope bullet. Out of Scope is unchanged and consistent: operating runners stays out, and the new assumption says S03 provides the privileged runner. |
| 5 | Stakeholders are cross-referenced to Stakeholder Analysis IDs rather than re-described inline | Pass | Unchanged; the new assumption names S03. |
| 6 | Methodology and quality-standard foundation are stated explicitly (e.g. ISO/IEC 25010, Larman) | Pass | Unchanged. |
| 7 | Assumptions and constraints are explicit and clearly distinguished from one another | Pass | The assumption (S03 provides a runner with `NET_ADMIN` and `/dev/net/tun`) and the constraint (a VPN key or token never appears in a log, an artifact or a command line) are in their own sections. |
| 8 | Document supports executive decision-making with a clear, unambiguous recommendation | Pass | Unchanged: Proceed. |

## Overall Verdict

Go - all eight criteria pass for the revision that adds objective O6, its scope item, assumption, constraint and success criterion 6. The author confirmed the acceptance in chat on 2026-10-19 as stand-in for S01; there is no independent reader and the decision stays open to challenge.

## Action Items

| Action | Owner | Due |
| --- | --- | --- |
| The Metadata table of BC-001 has no `Language` and `Domain` rows (QC-LANG-001 criterion 1); this predates this change and is carried over from [RC-067]. Add the rows or record in an ADR why they are not needed | S01 | Before the next material change to BC-001 |
