Modularize Journal Entry view and refine UI logic

- Extracted AI Tools and Metadata into dedicated Svelte 5 components (JournalEntry_AITools, JournalEntry_Metadata).
- Standardized iconography to Lucide across list and detail views.
- Refined sort order controls with improved styling and Lucide icons.
- Fixed 'OpenAI is not defined' ReferenceError by restoring necessary imports.
- Corrected component naming discrepancy for Journal_entry_obj_file_li.
- Hardened change detection using Svelte 5 .by for reliable Save button behavior.

 ### Session Learnings (2026-01-08)
 
-**Context:** Refactored the core Aether API helper suite (`get`, `post`, `patch`, `delete`) to ensure architectural consistency, robust error handling, and support for unauthenticated lookups (the "Bootstrap Paradox").
+**Context:** Finalized the core Aether API stack refactor, achieved 100% unified type parity for all 42 active interfaces, and initiated the Journals module UI/UX audit.
 
 **Key Accomplishments:**
-- **API Helper Alignment:** Standardized all primary helpers to support custom `fetch` injection (essential for SvelteKit SSR), kebab-case header standardization, and automated JWT-to-Authorization header injection.
-- **Bootstrap Paradox Resolution:** Implemented a robust bypass in the header merging logic. By passing `x-no-account-id: null` to the helpers, the default `x-account-id` is stripped, and a non-null dummy value is sent, allowing unauthenticated V3 searches for site domains.
-- **Non-Mutating Config:** Eliminated direct mutations of the shared `api_cfg` object within the helpers, preventing difficult-to-track side effects across the application.
-- **System Testing Dashboard:** Upgraded the `/testing` page with a dedicated suite for core helper verification and V3 search validation.
-- **CLI Verification Suite:** Created `agents_sync/scripts/test_ae_api_v3.py` for rapid, headless verification of the API stack from the command line.
+- **API Helper Alignment:** Standardized all primary helpers (`get`, `post`, `patch`, `delete`) to support custom `fetch` injection (essential for SvelteKit SSR), kebab-case header standardization, and automated JWT-to-Authorization header injection.
+- **Bootstrap Paradox Resolution:** Implemented a robust bypass in the header merging logic. By passing `x-no-account-id: null` to the helpers, the default `x-account-id` is stripped and a dummy string sent, allowing unauthenticated V3 searches.
+- **MISSION COMPLETE (Unified Types):** Established `src/lib/types/ae_types.ts` and migrated all 42 active Aether interfaces. Standardized on the "Triple-ID" pattern (`id`, `[type]_id`, `[type]_id_random`) for Dexie and V3 API compatibility.
+- **Journals Module Refinement:** Standardized iconography to Lucide, improved header responsiveness for mobile/tablet, and implemented a robust 3-state toggle (View/Cancel/Save) for journal entries using Svelte 5 `$derived.by` for reactive change detection.
+- **CodeMirror Evolution:** Refactored the editor component to support `bind:value` and exposed the internal `editorView` for external control. Preserved formatting logic in `ae_journals_editor_helpers.ts`.
 
 **Key Learnings:**
-- **Implicit Header Requirements:** Some backend environments (like the Aether V3 API) strictly require the presence of a "bypass" header even when credentials are omitted. A null value in the client-side header map is often stripped by `fetch`, so a dummy string value (e.g., "Nothing to See Here") is necessary for the header to be successfully transmitted.
-- **Environment Parity in Testing:** Verifying API helpers in both the browser (via the `/testing` page) and the CLI (via Python scripts) is critical for identifying environment-specific issues like CORS, header formatting, and timeout behavior.
-- **Barrel File Strategy:** As the API stack grows, a pure barrel file strategy for `api.ts` (exporting from dedicated modules) is superior to a single "God Object" for maintainability and code splitting.
+- **Svelte 5 Change Detection:** Using `$derived.by` for complex object comparison (e.g., comparing `tmp_entry_obj` vs `orig_entry_obj`) is significantly more reliable and predictable than `$effect`-based detection for UI state toggles.
+- **CodeMirror 6 Transactions:** CM6 is extremely strict about its update cycle. Overriding the low-level `dispatch` can lead to deadlocks with Svelte's reactivity. The `EditorView.updateListener` pattern is the safer way to sync state.
+- **Header "Presence" vs "Value":** Backend V3 guest lookups sometimes require the *presence* of a bypass header even if the value is a dummy string. `fetch` may strip `null` headers entirely, so a non-empty string like "Nothing to See Here" is functionally required.
+
+**Known Challenges:**
+- **Editor Toolbar:** The formatting toolbar (`wrapSelection`) is currently commented out in the Journal Entry view. While the logic is sound, it triggered `TypeError` in the CodeMirror core during transactions. This needs isolated testing before re-enablement.
+
+**Next Steps:**
+- **Journals Audit (Phase 2):** Clean up the Journals configuration and category menus. Remove legacy CSS in favor of Tailwind.
+- **Core UI Expansion:** Build dedicated Create/Edit forms for `Person`, `Address`, and `Contact` using the new unified types.
+- **CodeMirror Tooling:** Stabilize the formatting helpers and re-enable the Markdown toolbar.
