+## [0.3.0] - 2026-04-20
+
+### Added
+
+- Added a shared paired-evidence contract in `roboharness.approval.evidence`,
+  including bounded path resolution plus reusable lightbox/image helpers for
+  approval surfaces.
+- Added a second concrete consumer of that contract with
+  `examples/g1_cross_framework_report.py`, backed by the committed
+  `assets/g1/X36_Y28_Z13/` Meshcat-vs-MuJoCo proof bundle.
+- Added a seeded MuJoCo approval corpus covering `good`, `bad`, and `ambiguous`
+  review outcomes to lock the surfaced-case trust boundary.
+- Added a script-level regression test proving `examples/mujoco_grasp.py`
+  exits cleanly and writes `contract_compile_error.json` when contract
+  compilation fails before execution.
+
+### Changed
+
+- Refactored the MuJoCo unattended-approval wedge to use the shared evidence
+  contract instead of keeping paired-evidence logic local to the example.
+- Expanded the MuJoCo proof surface with temporal evidence strips and
+  click-to-zoom lightbox support for ambiguous or detail-heavy review cases.
+- Added reviewed contract preset selection plus constrained prompt-assisted
+  preset selection to `examples/mujoco_grasp.py`, while keeping unsupported
+  open-ended authoring fail-closed.
+- Rewrote the README front door around the unattended approval wedge, with a
+  clearer split between package-first integration and the repo-only MuJoCo demo.
