+## v0.9.5 — Typed Forms → SDK Primitive
+
+Promotes the typed form system from a workflow-only model to a reusable
+SDK primitive. Any package can now declare and validate forms — not just
+workflow stages.
+
+**Backend — `server/forms/` package**
+
+- Extracted `TypedFormTemplate`, `FormField`, `FormFieldset`, `FormOption`,
+  `FormValidation`, `FieldCondition`, `FormHooks`, `FieldError` from
+  `models/workflow.go` into standalone `forms` package.
+- `ParseTypedFormTemplate()`, `ValidateFormData()`, `EvaluateFieldCondition()`
+  exported for use by any consumer.
+- ~317 lines removed from `models/workflow.go` (no external imports existed).
+
+**REST endpoint**
+
+- `POST /api/v1/forms/validate` — authenticated endpoint. Accepts
+  `{template, data}`, returns `{valid: bool, errors: [{key, message}]}`.
+
+**Starlark module**
+
+- `forms.validate(template, data)` — gated by `forms.validate` permission.
+  Returns dict with `valid` (bool) and `errors` (list of dicts).
+
+**Frontend SDK**
+
+- `sw.forms.render(container, template, opts)` — Preact component rendering
+  flat and progressive (fieldset) forms. Returns `{getData, setErrors, destroy}`.
+- `sw.forms.validate(template, data)` — client-side validation (mirrors Go logic).
+- `sw.forms.validateRemote(template, data)` — server-side validation via REST.
+- SDK version bumped to `0.9.5`.
+
+**Manifest validation**
+
+- `form_template` accepted at package level. Validated via
+  `forms.ParseTypedFormTemplate()` at install time.
+- `ManifestInfo.HasFormTemplate` flag added.
+
+**Tests**
+
+- 16 new tests: 12 forms package unit tests (parse, validate by type,
+  conditions, fieldsets), 4 Starlark module tests (valid, required,
+  type errors, conditions).

 ## v0.9.4 — Package Adoption + Roles
 
 Packages can now declare `adoptable: true` in their manifest. When a team
