 All notable changes to the Design-to-Code Bridge plugin are documented here. Follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/) and [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [0.2.0] — 2026-05-19
+
+### Added
+
+- **Gate 6 — Data binding.** New gate sits between Component mapping (Gate 5) and Slice plan. Classifies every mapped unit as `backend` (wire to an existing service), `mock` (emit a schema + JSON + TS-interface triple under hierarchical `data/<page>/<subpage>/`), or `none` (decorative). Low-confidence rows must be acknowledged before advancing.
+- **`design-to-code-data-binder` subagent** — 7th subagent, owns Gate 6. Walks the consumer's `lib/services/`, `hooks/`, and route tree to propose the binding tier per unit and queue mock-file triples for the planner.
+- **`templates/gate-failures/6-data-binding.md`** — per-gate failure message template for low-confidence bindings, page/subpage conflicts, and backend overrides.
+
+### Changed
+
+- **Gate renumbering** (breaking change for any consumer reading gate numbers from `status.json`):
+  - Slice plan: Gate 6 → Gate 7
+  - Pre-slice: Gate 7 → Gate 8
+  - Pre-swap: Gate 8 → Gate 9
+  - Pre-retro: Gate 9 → Gate 10
+- **`templates/gate-failures/9-pre-retro.md` → `10-pre-retro.md`** (renamed).
+- **`agents/design-to-code-pm.md`** — updated to reference "eleven gates"; Gate 6 section added between Gate 5 and Gate 7.
+- **`DESIGN_TO_CODE_RULES.md`** — expanded to document the data-binding gate and the hierarchical `data/<page>/<subpage>/` convention (~24% growth).
+
+### Notes
+
+- This is a breaking change for any consumer who has frozen `status.json` snapshots from v0.1.0 — gate numbers ≥ 6 have shifted by 1. Run `/design-to-code:start` on existing features to re-validate against the new gate ordering.
