 # Changelog
 
+## [0.12.2.0] - 2026-03-26 — Deploy with Confidence: First-Run Dry Run
+
+The first time you run `/land-and-deploy` on a project, it does a dry run. It detects your deploy infrastructure, tests that every command works, and shows you exactly what will happen... before it touches anything. You confirm, and from then on it just works.
+
+If your deploy config changes later (new platform, different workflow, updated URLs), it automatically re-runs the dry run. Trust is earned, maintained, and re-validated when the ground shifts.
+
+### Added
+
+- **First-run dry run.** Shows your deploy infrastructure in a validation table: platform, CLI status, production URL reachability, staging detection, merge method, merge queue status. You confirm before anything irreversible happens.
+- **Staging-first option.** If staging is detected (CLAUDE.md config, GitHub Actions workflow, or Vercel/Netlify preview), you can deploy there first, verify it works, then proceed to production.
+- **Config decay detection.** The dry-run confirmation stores a fingerprint of your deploy config. If CLAUDE.md's deploy section or your deploy workflows change, the dry run re-triggers automatically.
+- **Inline review gate.** If no recent code review exists, offers a quick safety check on the diff before merging. Catches SQL safety, race conditions, and security issues at deploy time.
+- **Merge queue awareness.** Detects when your repo uses merge queues and explains what's happening while it waits.
+- **CI auto-deploy detection.** Identifies deploy workflows triggered by the merge and monitors them.
+
+### Changed
+
+- **Full copy rewrite.** Every user-facing message rewritten to narrate what's happening, explain why, and be specific. First run = teacher mode. Subsequent runs = efficient mode.
+- **Voice & Tone section.** New guidelines for how the skill communicates: be a senior release engineer sitting next to the developer, not a robot.

 ## [0.12.1.0] - 2026-03-26 — Smarter Browsing: Network Idle, State Persistence, Iframes
 
 Every click, fill, and select now waits for the page to settle before returning. No more stale snapshots because an XHR was still in-flight. Chain accepts pipe-delimited format for faster multi-step flows. You can save and restore browser sessions (cookies + open tabs). And iframe content is now reachable.
