+# PR_26175_OWNER_055-legal-governance-leftover-retention
+
+## Purpose
+Retain the legal/governance leftover artifacts that remained after `PR_26175_OWNER_054-legal-corrected-package` was merged and `main` was synchronized.
+
+## Source Leftovers
+The previous `MAIN_VERIFY` identified three untracked leftover paths:
+
+| Path | Classification | Retention decision |
+| --- | --- | --- |
+| `docs_build/legal/IMPLEMENTATION.md` | Legal package implementation/source notes | Retained in this follow-up PR. |
+| `docs_build/legal/LEGAL_CHANGELOG.md` | Legal foundation package governance notes | Retained in this follow-up PR. |
+| `docs_build/dev/reports/PR_26175_OWNER_current-open-pr-status.md` | Generated governance status report | Retained as a snapshot report in this follow-up PR. |
+
+## Implementation
+- Added the retained package implementation instructions at `docs_build/legal/IMPLEMENTATION.md`.
+- Added the retained legal changelog at `docs_build/legal/LEGAL_CHANGELOG.md`.
+- Updated and retained `docs_build/dev/reports/PR_26175_OWNER_current-open-pr-status.md` as a current governance snapshot taken after OWNER_054 was merged and before OWNER_055 was opened.
+- Added OWNER_055 plan, validation, checklist, manual validation, changed-files, review-diff, and delta ZIP outputs.
+- Confirmed no `IMPLEMENTATION.md` file remains at the repository root.
+
+## Validation Commands
+- PASS: `git status --short --branch`
+- PASS: `git rev-list --left-right --count origin/main...HEAD`
+- PASS: `git diff --name-only`
+- PASS: `git diff --check`
+- PASS: targeted retained-file existence checks.
+- PASS: targeted root `IMPLEMENTATION.md` absence check.
+- PASS: targeted changed-file scope check confirmed documentation/governance/report files only.
+
+## Guardrails
+- No product files were modified.
+- No runtime code was modified.
+- No `IMPLEMENTATION.md` file remains at the repository root.
+- No branches were deleted.
+- `stash@{0}` was left untouched.
+- No leftover file was moved to `tmp/`.
+- No leftover file was deleted.
+
+## Delta ZIP
+Repo-structured delta ZIP:
+
+`tmp/PR_26175_OWNER_055-legal-governance-leftover-retention_delta.zip`

+# PR_26175_OWNER_055-legal-governance-leftover-retention Manual Validation Notes
+
+## Manual Review
+- Confirmed `docs_build/legal/IMPLEMENTATION.md` contains legal foundation implementation instructions/source notes rather than unrelated temporary content.
+- Confirmed `IMPLEMENTATION.md` is not present at the repository root.
+- Confirmed `docs_build/legal/LEGAL_CHANGELOG.md` belongs to the legal foundation package governance notes.
+- Confirmed `docs_build/dev/reports/PR_26175_OWNER_current-open-pr-status.md` is a generated governance report snapshot.
+- Confirmed this PR does not intentionally alter product files, runtime code, UI, legal page rendering, branches, or stashes.
+
+## Notes
+- `stash@{0}` remains untouched.
+- Retained files were committed to preserve legal/governance provenance after OWNER_054.
+- No owner-approved move-to-`tmp/` or deletion action was performed.

+## MAIN_VERIFY Snapshot
+| Item | Result |
+| --- | --- |
+| Current branch at verification | `main` |

+| Local/origin sync | `0 0` |
+| Open PR count before OWNER_055 | `0` |
+| Draft PR count before OWNER_055 | `0` |
+| Worktree state before OWNER_055 branch | Dirty, untracked leftovers only |
+| Product files modified | No |
+| Stashes altered | No |
+
+## Retained Leftovers
+| Path | Classification | OWNER_055 disposition |
+| --- | --- | --- |
+| `docs_build/legal/IMPLEMENTATION.md` | Legal package implementation/source notes | Retain in legal governance follow-up PR. |
+| `docs_build/legal/LEGAL_CHANGELOG.md` | Legal foundation package governance notes | Retain in legal governance follow-up PR. |

+# Legal Foundation Implementation Instructions
+
+## PR
+
+Use:
+
+`PR_26175_OWNER_050-legal-foundation`
+
+## Goal
+
+Publish the initial Game Foundry Studio legal foundation.
+
+## Required Pages
+
+Create or update:
+
+```text
+/legal/index.html
+/legal/terms-of-service.html
+/legal/privacy-policy.html
+/legal/cookie-policy.html
+/legal/community-guidelines.html
+/legal/copyright-policy.html
+/legal/dmca-policy.html
+/legal/legal-nav.js
+```
+
+## Source Drafts
+
+Use the markdown files in `/legal/` from this package as the source content for the HTML pages.
+
+## Single Source of Truth Legal Menu
+
+The left-side legal menu on all legal pages must be rendered from one shared source of truth.
+
+Do not duplicate legal side-menu links in each HTML file.
+
+Suggested file:
+
+```text
+/legal/legal-nav.js
+```
+
+Suggested SSoT:
+
+```js
+const LEGAL_NAV_ITEMS = [
+  { href: "/legal/index.html", label: "Legal Overview" },
+  { href: "/legal/terms-of-service.html", label: "Terms of Service" },
+  { href: "/legal/privacy-policy.html", label: "Privacy Policy" },
+  { href: "/legal/cookie-policy.html", label: "Cookie Policy" },
+  { href: "/legal/community-guidelines.html", label: "Community Guidelines" },
+  { href: "/legal/copyright-policy.html", label: "Copyright Policy" },
+  { href: "/legal/dmca-policy.html", label: "DMCA Policy" }
+];
+```
+
+Each legal page should include only a mount point:
+
+```html
+<nav class="legal-side-nav" aria-label="Legal documents" data-legal-nav></nav>
+```
+
+Required JavaScript behavior:
+
+- Render the legal navigation links from `LEGAL_NAV_ITEMS`.
+- Detect the current page from `window.location.pathname`.
+- Normalize `/legal/` to `/legal/index.html`.
+- Apply an active/current class to the matching legal page.
+- Set `aria-current="page"` on the active link.
+- Preserve keyboard and tab accessibility.
+- Do not require inline event handlers.
+
+Suggested current-page logic:
+
+```js
+function normalizeLegalPath(pathname) {
+  if (pathname.endsWith("/legal/")) return "/legal/index.html";
+  if (pathname === "/legal") return "/legal/index.html";
+  return pathname;
+}
+```
+
+## Layout Requirements
+
+- Use the existing Game Foundry Studio site shell/template where appropriate.
+- Legal pages should use a two-column layout on desktop:
+  - Left: shared legal side navigation
+  - Right: legal document content
+- On small screens, the legal navigation may stack above the content.
+- Keep the legal pages readable and accessible.
+- Do not introduce unrelated UI changes.
+
+## Footer Links
+
+Add footer links to:
+
+- Terms
+- Privacy
+- Cookies
+- Community Guidelines
+- Copyright
+- DMCA
+
+Footer links may point to the corresponding `/legal/*.html` pages.
+
+## Validation Requirements
+
+Run the repository's relevant validation before opening the PR.
+
+At minimum:
+
+- HTML validation or existing static-page checks, if present
+- JS syntax check for `/legal/legal-nav.js`
+- Existing legal/nav/footer tests, if present
+- Any repository-required governance validation
+
+## Acceptance Criteria
+
+- All six legal documents are published as HTML pages.
+- `/legal/index.html` links to all legal documents.
+- Footer includes legal links.
+- Legal side navigation is generated from one SSoT.
+- Current page is visually selected.
+- Current page has `aria-current="page"`.
+- No page has a hand-maintained duplicate left legal menu.
+- No unrelated code, route, database, API, or storage changes.

+# PLAN PR_26175_OWNER_055-legal-governance-leftover-retention
+
+Source of truth: user request `PLAN_PR PR_26175_OWNER_055-legal-governance-leftover-retention`.
+
+## Purpose
+Retain the legal/governance leftover artifacts identified after `PR_26175_OWNER_054-legal-corrected-package` was merged, using a small documentation-only follow-up PR.
+
+## Scope
+Primary target files:
+- `docs_build/legal/IMPLEMENTATION.md`
+- `docs_build/legal/LEGAL_CHANGELOG.md`
+- `docs_build/dev/reports/PR_26175_OWNER_current-open-pr-status.md`

+- `tmp/PR_26175_OWNER_055-legal-governance-leftover-retention_delta.zip`
+
+## Required Changes
+- Retain `docs_build/legal/IMPLEMENTATION.md` because it contains legal package implementation/source notes.
+- Retain `docs_build/legal/LEGAL_CHANGELOG.md` because it belongs to the legal foundation package governance notes.
+- Retain `docs_build/dev/reports/PR_26175_OWNER_current-open-pr-status.md` as a generated governance report snapshot.
+- Add the normal OWNER_055 plan, validation, checklist, manual notes, changed-files, review-diff, and ZIP outputs.
+
+## Validation
+Run only:
+- `git status --short --branch`
+- `git rev-list --left-right --count origin/main...HEAD`
+- `git diff --name-only`
+- `git diff --check`
+- Targeted checks that retained files and required OWNER_055 reports exist.
+- Targeted check that changed files are documentation/governance/report files only.
+
+## Non-goals
+- Do not modify product files.
+- Do not modify runtime code.
+- Do not delete branches.
+- Do not alter stashes.
+- Do not move leftovers to `tmp/`.
+- Do not delete leftovers.
