+**Context:** Finalized IDAA Bulletin Board V3 migration, implemented global `editable_fields.ts` whitelists, and standardized JWT authentication for CRUD V3. Resolved the "Bootstrap Paradox" for site domain lookups.
 
 **Key Accomplishments:**
 - **JWT Authentication:** Standardized JWT usage across all CRUD V3 operations. Updated API helpers to automatically inject `Authorization: Bearer` headers and added secure file download support via `jwt` URL parameters.

 - **Race Condition Resolution:** Identified and fixed a race condition during database refresh by `await`ing Dexie `.clear()` operations.
 - **Global Editable Field Whitelists:** Successfully created `.editable_fields.ts` whitelist files for all remaining Aether objects (Journals, Events, Sponsorships).
 - **Bug Fix:** Resolved a critical `ReferenceError` in the POST helper that was causing 500 errors during site lookup.
+- **Bootstrap Paradox Resolution:** Successfully implemented and verified `lookup_site_domain_v3` using unauthenticated POST `/v3/crud/site_domain/search`. Modified the function to aggressively strip all authentication headers (`Authorization`, `x-account-id`, `jwt`) to satisfy the backend guest-access requirement.
+- **Enhanced Verification UI:** Upgraded `/testing` page with custom FQDN input, `try...catch` error handling, and robust result visualization to debug V3 site lookups without affecting the root layout.
 
 **Key Learnings:**
 - **Header Normalization:** When merging headers in API helpers, ensure consistent kebab-case normalization (e.g., `Authorization` instead of `authorization`) to match backend expectations and avoid duplicates.
 - **Secure Direct Access:** For direct browser-led requests like file downloads, passing the JWT as a URL parameter is a robust alternative to header-based auth which can be difficult to set on standard `<a>` or `<img>` tags.
 - **IndexedDB Filter Consistency:** When using client-side filtering (e.g., `liveQuery`) on fields like `account_id`, it is vital that the frontend data processors inject these IDs if the API response omits them (common in nested V3 routes).
 - **Asynchronous DB Operations:** Always `await` database cleanup operations (`.clear()`) before triggering new data loads to prevent stale data or empty lists due to race conditions.
+- **Bootstrap Auth Isolation:** Guest endpoints like `site_domain/search` are extremely sensitive to any authentication headers. Even an empty or "fake" token can trigger a `403 Forbidden` if the backend doesn't explicitly ignore them.
+- **API Response Robustness:** The V3 API can return different response envelopes (some with `.data`, some without). Frontend helpers should use `json.data !== undefined ? json.data : json` to be truly resilient.
+- **Custom Fetch Alignment:** `post_object` must be refactored to use the SvelteKit `fetch` (if provided in `api_cfg`) to ensure consistent behavior across different environments (browser vs server vs test) and to match the implementation in `get_object`.
 
 **Next Steps:**
 - **Person Management:** Build out dedicated edit forms and finalize the "Linked Activity & Content" section.
 - **Address/Contact Details:** Implement detail pages for these newly added modules.
 - **Coordination:** Continue checking `agents_sync/inbox` for API V3 updates from the backend agent.
+- **API Helper Refactoring:** Implement the identified `post_object` improvements (custom fetch and robust extraction).
