+- **CWE-78 regression in `expandWithEnv` POSIX-identifier guard fixed (Critical)**: the shell-identifier guard in `expandWithEnv` (`org_helpers.go:82`) was inadvertently removed during a regression window between staging and main promotion. This guard prevents org YAML configurations from expanding invalid shell identifiers (e.g. `${HOME}`, `${DOCKER_HOST}`, `${AWS_SECRET_ACCESS_KEY}`) as environment variables — blocking secret exfiltration via malicious `workspace_dir` or channel config fields. Restored with regression tests covering `${0}`, `${5}`, `${1VAR}`, `${}`, `$0`, `$5`. Full advisory: [Security Changelog](/docs/security/changelog). (`molecule-core` [#1030](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1030))
+- **OFFSEC-003: workspace-side A2A boundary marker escaping (trust boundary hardening)**: the `tool_delegate_task` workspace tool now wraps delegation output with `_A2A_BOUNDARY_START_ESCAPED` / `_A2A_BOUNDARY_END_ESCAPED` instead of raw markers, preventing raw boundary markers from leaking into output alongside their escaped form. Additionally, responses containing the raw closer `[A2A_RESULT_FROM_PEER]` are now truncated before sanitization — so injection of the raw closer cannot be retroactively re-added by the sanitization pass. Together with the platform-side sanitization (shipped 2026-05-11), this closes the full OFFSEC-003 trust-boundary for delegation result delivery.

+### 🐛 Bug fixes
+
+- **Canvas WCAG 1.4.3 contrast ratio fixed for TIER_CONFIG legend**: the tier legend text in the canvas now meets the 4.5:1 contrast ratio required by WCAG 1.4.3 for normal text. (`molecule-core` [#990](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/990))
+- **Canvas focus-visible rings added to icon and text buttons**: focus-visible rings (`focus-visible:ring-2`) now render on icon buttons and text-only buttons in the canvas, restoring WCAG 2.1 AA compliance for all interactive elements. (`molecule-core` [#988](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/988))
+- **OpenClaw template `models` config moved to correct level**: the OpenClaw workspace template's `config.yaml` had `models` at the top level, but the platform template handler reads from `runtime_config.models`. This caused `/templates` to return empty models and providers → a blank "Missing API Keys" dialog with no selectable providers, disabling the Deploy button. Moved all model entries under `runtime_config` and added Groq and OpenRouter as alternative providers alongside OpenAI. (`molecule-ai-workspace-template-openclaw` [#4](https://git.moleculesai.app/molecule-ai/molecule-ai-workspace-template-openclaw/pulls/4))

+### 🧹 Internal

+- **CI infrastructure improvements** (`molecule-core`): `ci-required-drift` workflow updated with job-level `if:` guards to skip `github.ref`-gated jobs in the merge-queue context; `canvas-build` job now has an explicit 20-minute timeout; gitea merge-queue test mocks updated to match current push-gate behavior. (`molecule-core` [#1029](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1029), [#1006](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1006), [#1035](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1035))
+- **Handler test coverage additions** (`molecule-core`): 60+ new SQL-mock test cases covering `InstructionsHandler`, `ScheduleHandler` (28 cases), and the `expandWithEnv` POSIX guard regression suite. (`molecule-core` [#1030](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1030), [#1005](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/1005), [#999](https://git.moleculesai.app/molecule-ai/molecule-core/pulls/999))
