 # Changelog
 
+## 0.5.1 — 2026-03-17
+
+- **Know where you stand before you ship.** Every `/plan-ceo-review`, `/plan-eng-review`, and `/plan-design-review` now logs its result to a review tracker. At the end of each review, you see a **Review Readiness Dashboard** showing which reviews are done, when they ran, and whether they're clean — with a clear CLEARED TO SHIP or NOT READY verdict.
+- **`/ship` checks your reviews before creating the PR.** Pre-flight now reads the dashboard and asks if you want to continue when reviews are missing. Informational only — it won't block you, but you'll know what you skipped.
+- **One less thing to copy-paste.** The SLUG computation (that opaque sed pipeline for computing `owner-repo` from git remote) is now a shared `bin/gstack-slug` helper. All 14 inline copies across templates replaced with `eval $(gstack-slug)`. If the format ever changes, fix it once.
+
+### For contributors
+
+- Added `{{REVIEW_DASHBOARD}}` resolver to `gen-skill-docs.ts` — shared dashboard reader injected into 4 templates (3 review skills + ship).
+- Added `bin/gstack-slug` helper (5-line bash) with unit tests. Outputs `SLUG=` and `BRANCH=` lines, sanitizes `/` to `-`.
+- New TODOs: smart review relevance detection (P3), `/merge` skill for review-gated PR merge (P2).
+
 ## 0.5.0 — 2026-03-16
 
 - **Your site just got a design review.** `/plan-design-review` opens your site and reviews it like a senior product designer — typography, spacing, hierarchy, color, responsive, interactions, and AI slop detection. Get letter grades (A-F) per category, a dual headline "Design Score" + "AI Slop Score", and a structured first impression that doesn't pull punches.

+
+### Smart review relevance detection
+
+**What:** Auto-detect which of the 4 reviews are relevant based on branch changes (skip Design Review if no CSS/view changes, skip Code Review if plan-only).
+
+**Why:** Currently dashboard always shows 4 rows. On docs-only changes, "Design Review: NOT YET RUN" is noise.
+
+**Context:** /plan-design-review and /qa already do file-type detection in diff-aware mode. Could reuse that heuristic. Would require a `gstack-diff-scope` helper or enriching `gstack-slug` to also output change categories.

+**Depends on:** Ship Confidence Dashboard (shipped)
+
+### /merge skill — review-gated PR merge
+
+**What:** Create a `/merge` skill that merges an approved PR, but first checks the Review Readiness Dashboard and runs `/review` (Fix-First) if code review hasn't been done. Separates "ship" (create PR) from "merge" (land it).
+
+**Why:** Currently `/review` runs inside `/ship` Step 3.5 but isn't tracked as a gate. A `/merge` skill ensures code review always happens before landing, and enables workflows where someone else reviews the PR first.
+
+**Context:** `/ship` creates the PR. `/merge` would: check dashboard → run `/review` if needed → `gh pr merge`. This is where code review tracking belongs — at merge time, not at plan time.
