Navigate lane

Keep the four-bucket map stable while content moves. Open Start Here or Check the SLI map. Exit metric: 404 crawl passes and /legacy traffic stays <5% during the freeze.

Tiny receipts — Navigate (v2025.11)

• Nav skeleton: 4-of-4 buckets visible with opener pattern
• /legacy traffic: 3.4% (Cloudflare 7-day lookback) See the receipts

Hold the frame

1. Lock the buckets — Home hero + top nav must show Navigate · Operate · Learn · Mitigate every release.
2. Mirror the opener — Each landing keeps one sentence why, two CTAs, and an exit metric above the first heading.
3. Surface receipts — Link the seam receipts for every landing (Navigate uses v2025.11-navigate).

Use Start Here for orientation copy; keep this page focused on the governance skeleton.

Redirects & legacy

• /legacy renders the published banner and points visitors to /start-here/.
• Every moved path lands in ops/redirect_ledger.csv with lower-case, single-hop entries.

Receipts & monitoring

• /legacy traffic stays <5% — track via Cloudflare nav dashboard and log deltas in Navigate receipts.
• 404 crawl = 0 blockers — tie runs to pnpm run drift:check and capture proof in the release bundle.
• Exceptions older than 14 days halt moves; close them or stop migrating until they’re green.
