+Add dual profile system with separate Bluesky and Certified profile operations, plus upsert methods
+
+**Core SDK (`@hypercerts-org/sdk-core`):**
+
+**Breaking Changes:**
+
+The profile API has been completely redesigned to support two profile types:
+
+- **Removed generic profile methods:**
+  - ❌ `profile.get()`
+  - ❌ `profile.create(params)`
+  - ❌ `profile.update(params)`
+
+- **Removed deprecated profile types:**
+  - ❌ `HypercertProfile` - Use `CertifiedProfileRecord` instead
+  - ❌ `CreateHypercertProfileParams` - Use `CreateCertifiedProfileParams` instead
+  - ❌ `UpdateHypercertProfileParams` - Use `UpdateCertifiedProfileParams` instead
+  - ❌ `HypercertProfileParams` - Use specific create/update types instead
+  - ❌ `CreateProfileParams` - Use `CreateCertifiedProfileParams` instead
+
+- **Removed unused type export:**
+  - ❌ `JsonBlobRef` - No longer used in SDK. This type was removed because:
+    - It was too "snowflaky" - required converting `BlobRef` instances to JSON format unnecessarily
+    - The actual `BlobRef` object works perfectly fine for all use cases
+    - It created flaky tests where we manually created mock JSON objects that weren't representative of actual
+      `JsonBlobRef` values
+    - Internal implementation now uses `BlobRef` instances directly throughout
+    - Users who need this type for advanced use cases can import it directly from `@atproto/lexicon`
+
+- **Added profile-specific methods:**
+  - ✅ `profile.getBskyProfile()` - Get Bluesky profile (app.bsky.actor.profile)
+  - ✅ `profile.createBskyProfile(params)` - Create Bluesky profile
+  - ✅ `profile.updateBskyProfile(params)` - Update Bluesky profile
+  - ✅ `profile.getCertifiedProfile()` - Get Certified profile (app.certified.actor.profile) **[Returns `null` if
+    profile doesn't exist]**
+  - ✅ `profile.createCertifiedProfile(params)` - Create Certified profile
+  - ✅ `profile.updateCertifiedProfile(params)` - Update Certified profile
+  - ✅ `profile.upsertBskyProfile(params)` - Create or update Bluesky profile **[New]**
+  - ✅ `profile.upsertCertifiedProfile(params)` - Create or update Certified profile **[New]**
+
+**Features:**
+
+- **Bluesky profiles** (`app.bsky.actor.profile`):
+  - Standard AT Protocol profiles
+  - Avatar/banner returned as CDN URLs (`https://cdn.bsky.app/...`)
+  - Includes Bluesky-specific fields (labels, pinnedPost, etc.)
+
+- **Certified profiles** (`app.certified.actor.profile`):
+  - Hypercerts-specific profiles with additional fields
+  - Avatar/banner returned as PDS blob URLs (`https://pds.../xrpc/...`)
+  - **`getCertifiedProfile()` returns `null` if profile doesn't exist** (not an error - common for new users)
+  - Supports `pronouns` field (max 20 graphemes)
+  - Supports `website` field
+  - Images stored using `HypercertImageRecord` format internally (smallImage/largeImage wrappers)
+
+- **Upsert methods** (Recommended for most use cases):
+  - `upsertBskyProfile(params)` - Automatically creates or updates Bluesky profile
+  - `upsertCertifiedProfile(params)` - Automatically creates or updates Certified profile
+  - Simpler DX - no need to check if profile exists first
+  - Perfect for "save profile" operations
+
+- **New types:**
+  - `BskyProfile` - Type for Bluesky profiles (alias for `AppBskyActorDefs.ProfileViewDetailed`)
+  - `CertifiedProfile` - Type for Certified profiles
+  - `CertifiedProfileRecord` - Record type for Certified profiles (replaces `HypercertProfile`)
+  - `CreateBskyProfileParams`, `UpdateBskyProfileParams`
+  - `CreateCertifiedProfileParams`, `UpdateCertifiedProfileParams` (replace `CreateHypercertProfileParams`,
+    `UpdateHypercertProfileParams`)
+
+**Migration Guide:**
+
+```typescript
+// BEFORE (old API - removed)
+const profile = await repo.profile.get();
+await repo.profile.create({ displayName: "Alice" });
+await repo.profile.update({ displayName: "New Name" });
+
+// AFTER - Recommended: Use upsert (works for both create and update)
+await repo.profile.upsertCertifiedProfile({
+  displayName: "Alice",
+  pronouns: "she/her",
+  website: "https://alice.com",
+});
+
+// AFTER - Advanced: Explicit create/update for fine control
+const certProfile = await repo.profile.getCertifiedProfile();
+if (!certProfile) {
+  await repo.profile.createCertifiedProfile({
+    displayName: "Alice",
+    pronouns: "she/her",
+  });
+} else {
+  await repo.profile.updateCertifiedProfile({
+    displayName: "New Name",
+  });
+}
+
+// Getting profiles - handle null case
+const profile = await repo.profile.getCertifiedProfile();
+if (profile) {
+  console.log(profile.displayName);
+} else {
+  console.log("User hasn't created a profile yet");
+}
+
+// Type migrations
+import type {
+  CertifiedProfileRecord, // was: HypercertProfile
+  CreateCertifiedProfileParams, // was: CreateHypercertProfileParams
+  UpdateCertifiedProfileParams, // was: UpdateHypercertProfileParams
+} from "@hypercerts-org/sdk-core/types";
+```
+
+**React SDK (`@hypercerts-org/sdk-react`):**
+
+**Breaking Changes:**
+
+- `useProfile` hook renamed `update` to `save` and `isUpdating` to `isSaving`
+- `save()` now uses upsert internally - works for first-time profile creation too
+
+```typescript
+// BEFORE
+const { update, isUpdating } = useProfile();
+await update({ displayName: "Alice" });
+
+// AFTER
+const { save, isSaving } = useProfile();
+await save({ displayName: "Alice" }); // Works even if profile doesn't exist!
+```
