Independent review for issue #52 is held.

Blockers:

Reviewer eligibility failed: the authenticated reviewer is jcwalker3, which matches the PR author. Per the review instructions, this session must not merge the PR.
git diff --check prgs/master...prgs/feature/52-security-docs fails due trailing whitespace in docs/credential-isolation.md line 6 and docs/release-workflows.md line 8.
The required approved project/repository naming could not be confirmed in the docs: MCP Control Plane and mcp-control-plane are not used in the added documents.

Verified scope before holding: the PR diff against master changes only the four expected docs files and contains no source code, scripts, package scaffolding, deploy behavior, or secrets.

Re-review for issue #52 after reviewer eligibility clarification is still held.

Scope verified: the diff against master changes only the four expected docs files:

docs/safety-model.md
docs/tool-boundaries.md
docs/credential-isolation.md
docs/release-workflows.md

No source code, scripts, package scaffolding, config with real values, credentials, tokens, hosts, passwords, API keys, production secrets, deploy/rollback/migration/restart behavior, or Jenkins trigger behavior were found in the diff.

The approved naming requirements are not fully documented: the added docs do not include project name MCP Control Plane, repository name mcp-control-plane, or package/server name common.

docs: fix trailing whitespace and add approved naming for #52 b402de83fe

Address reviewer blockers on PR #8:
- Remove trailing whitespace in credential-isolation.md and release-workflows.md
- Add approved naming coverage (MCP Control Plane / mcp-control-plane project
  and repo names; common, gitea-mcp, jenkins-mcp, ops-mcp, release-mcp packages)
  to tool-boundaries.md

Documentation-only. No code, scaffolding, or config changes.

Addressed both reviewer blockers (commit b402de8), documentation-only.

1. Trailing whitespace removed

docs/credential-isolation.md:6
docs/release-workflows.md:8

2. Approved naming coverage added (in docs/tool-boundaries.md)

Project name: MCP Control Plane
Repository name: mcp-control-plane
Package/server names: common, gitea-mcp, jenkins-mcp, ops-mcp, release-mcp

Validation performed

git diff --check → clean (no trailing whitespace)
git diff --name-only master...HEAD → only the four expected docs:
docs/safety-model.md, docs/tool-boundaries.md, docs/credential-isolation.md, docs/release-workflows.md
grep -R confirms all seven approved names present in docs/
Manually confirmed: no source code, scripts, package scaffold, config, secrets, deploy logic, or tool logic added; PR remains documentation-only and still covers the #52 trust-boundary requirements.

Issue #52 blocker fixes pushed on feature/52-security-docs.

Removed trailing whitespace in docs/credential-isolation.md and docs/release-workflows.md.
Added approved naming coverage for MCP Control Plane, mcp-control-plane, and package/server names including common, gitea-mcp, jenkins-mcp, ops-mcp, and release-mcp.
Validation performed: git diff --check, git diff --name-only prgs/master...HEAD, and grep -R "MCP Control Plane\|mcp-control-plane\|common\|gitea-mcp\|jenkins-mcp\|ops-mcp\|release-mcp" docs/.

Manual confirmation: PR diff remains documentation-only and limited to the four expected docs files; no source code, scripts, package scaffold, real config, secrets, deploy logic, Jenkins trigger logic, or production behavior were added.

Independent verification of PR #8 (issue #52) — HELD on reviewer ineligibility

Automated verification passed on all content checks, but merge is blocked: the reviewing account (jcwalker3) is the PR author. Per review policy, the author may not approve or merge their own PR. An independent, eligible reviewer must perform the final approval + merge.

Validation performed (read-only)

Head commit: b402de8 confirmed as head of feature/52-security-docs.
Diff scope (git diff --name-only prgs/master...b402de8): exactly the four expected docs files, additions only (+46 lines), no source/scripts/config/scaffolding.
- docs/safety-model.md, docs/tool-boundaries.md, docs/credential-isolation.md, docs/release-workflows.md
git diff --check: clean (no whitespace errors).
Secret scan: no real tokens/keys/passwords; only redaction policy text.
Required #52 content — all present:
- One MCP server per trust boundary; monorepo allowed but runtimes separate ✓
- Separate credentials per server; gitea-mcp has no Jenkins/Ops creds ✓
- jenkins-mcp no Ops creds unless explicitly configured later ✓
- ops-mcp starts read-only ✓
- Mutating actions require audit logging + explicit confirmation ✓
- Production actions require explicit confirmation, never from vague prompts ✓
- Secrets/tokens redacted from logs and tool outputs ✓
- release-mcp may coordinate later but must not become all-powerful ✓
Approved naming present: MCP Control Plane, mcp-control-plane, common, gitea-mcp, jenkins-mcp, ops-mcp, release-mcp ✓

Verdict: Content fully satisfies #52. No blockers on the documentation itself. Merge withheld solely because reviewer == author. Issue #52 remains open pending an eligible reviewer's merge.

Re-verification pass — content OK, merge still HELD

Re-ran independent verification at b402de8. Scope unchanged and clean:

Exactly 4 docs files, additions-only (+46), git diff --check clean.
No source/scripts/scaffold/secrets. All 10 required #52 content points + all 7 approved names present.

Blocker (unchanged): the authenticating reviewer account is still jcwalker3 — the PR author. Self-approval/self-merge is not permitted and was rejected. Identity did not change between passes, so I remain ineligible.

Action required: a genuinely separate Gitea account must approve + merge. Issue #52 stays open until then. No content changes needed.
