 ### 🎯 Strategic Goals (Current Sprint)
-- **Primary:** Performance Sprint & Journals Standardization.
+- **Primary:** Launcher Stabilization & Performance.
 - **Secondary:** V3 API Migration and System Health Stability.
 
 ### 🚧 Active Workstreams
+- **[Launcher Stabilization]:** Hardening the native bridge and resolving session selection reactivity issues.
 - **[Leads Module V3]:** Transitioning Exhibitor Leads to V3 API and mobile-first dashboard.
 - **[Hydration Optimization]:** Implemented SWR pattern and non-blocking layouts to eliminate "white page" delays.
 - **[Search Hardening]:** Standardized debounced reactive search logic across Recovery Meetings, Badge Search, and Journals modules.
-- **[Service Worker]:** Re-enabled registration and implemented robust asset caching.
 - **[Telemetry]:** Modern dashboard in Launcher Config with visual CPU/RAM gauges.
-- **[Journals Module]:** Standardized naming (`ae_comp__*`), normalized props to snake_case, and unified icons.
 
 ### 🧠 Recent Learnings & Decisions
-- **V3 Search Context:** POST search for child objects (e.g. `event_exhibit_tracking`) requires explicit `for_obj_type` and `for_obj_id` query parameters to assist the backend in partitioning, otherwise it may inject incorrect legacy filters like `event_id_random`.
-- **SWR Pattern:** Crucial for eliminating page load delays in Sites, Events, and Journals.
-- **Debounced Search:** Replacing manual triggers and loops (like setInterval) with reactive debounced effects significantly improves UX and reduces API noise.
-- **Quiet Logs:** Silenced noisy `AbortError` and `NetworkError` in background fetches to reduce noise.
-- **Details Toggle:** Optimized Event Session list by deferring expensive sub-components.
+- **LiveQuery Reactivity:** `liveQuery` observables require explicit prefixing ($) in templates. Re-assigning them to `$state` variables in effects can lead to `store_invalid_shape` errors if prefixes aren't updated.
+- **Global Page State:** Migrating from manual prop-passing (like `data_url`) to the global `$page` state significantly simplifies component trees and avoids "undefined" errors during navigation.
+- **Native Handover:** Using `.tmp` files for downloads and only renaming to `.file` after SHA-256 verification ensures cache integrity in the native bridge.

 ## 3. 🧠 Short Term Memory (Session Context)
 
-- **Status:** Session Concluded / System Stable.
+- **Status:** Session Concluded / System Reverted to Stable.
 
-- **Last Action:** Finalized V3 Leads foundations, fixed dashboard routing, and implemented booth management.
+- **Last Action:** Reverted uncommitted reactivity refactors in `launcher/+layout.svelte` and `launcher_session_view.svelte` due to page load failure.
 
 - **Key Learnings:**
 
-    - **Backend API Bug:** Identified a 400 Database Schema error in `event_exhibit_tracking` search caused by the backend incorrectly injecting legacy `event_id_random` filters. Frontend is verified clean and strictly follows base `_id` standards.
-
-    - **Nested Routing Logic:** Lead Detail routes MUST be nested under the Exhibit ID to maintain context and resolve 404 errors in the capturing workflow.
-
-    - **Property Processor Hardening:** Hardened processors to prioritize base `_id` mapping to internal `id` fields, ensuring robust Dexie synchronization for string-only identifiers.
+    - **Reactivity Race Conditions:** Manual store updates synchronized via URL can clash with layout effects, leading to clobbered states.
+    - **Svelte 5 Store Prefixes:** Standardizing on `$lq__obj` for observables is critical; switching to direct state variables requires surgical template updates.
 
 - **Accomplishments:**
 
-    - **V3 Leads Module Foundations:** Modularized `ae_events__exhibit` and `ae_events__exhibit_tracking` with V3 SWR standards and trace-ready performance logging.
+    - **'download' Filename Bug Fix:** Explicitly passed filenames to V3 Action endpoints and implemented a safety net in `api_get_object.ts`.
+    - **Menu Refactor:** Migrated `menu_session_list.svelte` and `menu_location_list.svelte` to use global `$page.url` state.
+    - **Native Caching:** Implemented SHA-256 verification and stale temp purge in the Electron bridge.
+    - **UI Initialization:** Ensured `event_session_id` defaults to `null` and added explicit no-session prompts.
 
-    - **String-Only ID Standardization:** Standardized all Lead capture and search functions to use base `_id` keys instead of the `_random` suffix dependency.
+- **Current Blocker:** Session Selection Hang (Page fails to load or UI hangs when selecting a session if starting from a path without an initial ID).
 
-    - **Leads Dashboard Orchestration:** Implemented a mobile-first, high-contrast dashboard with persistent tab navigation (Add Lead, Lead List, Manage).
-
-    - **Lead Detail Profile:** Implemented a comprehensive read-only Lead Profile view featuring custom responses and exhibitor notes.
-
-    - **Booth Management:** Implemented the Manage/Config tab using `Element_ae_crud_v2` for live-revalidating booth profile updates.
-
-- **Current Blocker:** Backend Search Bug for `event_exhibit_tracking` (injecting `event_id_random`).
-
-- **Immediate Next Step:** Verify Staff Sign-in workflow and License assignment logic once the search bug is resolved.
+- **Immediate Next Step:** Investigate Dexie/Svelte reactivity in the Launcher layout without introducing breaking clobbers.

 ## Gemini Added Memories
 
-- The Aether Docker environment now has a robust physical database management suite: restore_db.sh, check_and_import.sh, and export_db.sh. Password escaping issues resolved using single quotes in .env.
-
-- Standalone DB tests in API project: Use virtual environment at 'environment/bin/python3', extract credentials from container env, and manually construct SQLAlchemy URI to bypass 'app.config' dependency issues.
-
-- [Harden: ID Integrity] Generic object processors MUST use truthy checks when mapping `_random` variants to clean keys to prevent `null` or `undefined` values from clobbering valid linking IDs received from V3 API responses.
-
-- [Harden: Event File Loader] Implemented a "Safety Net" in `_refresh_file_li_background` to inject missing `for_id` and `for_type` from the query context before saving to Dexie, ensuring robust indexing even with partial API responses.
-
-- Centralized 'public_read' flag in object definitions (core.py, cms.py, etc.) controls guest access in V3 API.
-
-- V3 API 'view' parameter rollout complete across core event library modules.
-
-- Presentation Management reports utilize the 'alt' view for file data shapes.

+- [Native: Cache Reliability] Implemented SHA-256 integrity checks and stale `.tmp` purge in Electron `file_handlers.ts`.
+- [Layout: Page State] Use `page` from `$app/state` for layout-level store synchronization to avoid clobbering manual updates.
