 ### [Svelte] State reference warnings
 - [x] **`svelte-check` fully clean — 0 errors, 0 warnings.** All 42 `state_referenced_locally` warnings fixed (2026-03-11). CSS `@apply`/`@reference` warnings in `ae_idaa_comp__event_obj_id_edit.svelte` also resolved — Tailwind utilities inlined, `<style>` block removed. (2026-03-16)
 
+### [TypeScript] svelte-check hidden errors — discovered 2026-03-27
+**HOW WE FOUND THIS:** The `@lucide/svelte` 0.577.0 update (2026-03-10) dropped `class` from
+`IconProps`. Fixing it required a `declare module '@lucide/svelte'` augmentation. That
+augmentation was mistakenly placed in `app.d.ts`, which is a *script-context* declaration file
+(no `export {}`). In that context, `declare module` is an **ambient replacement**, not a merge —
+it wiped all icon exports from svelte-check's view, surfacing 1368 previously hidden errors.
+Once moved to `src/lucide-augment.d.ts` (a proper module file with `export {}`), the masking
+lifted and the real pre-existing errors became visible.
+
+**Lesson:** A broken ambient declaration can silently hide unrelated errors. If svelte-check
+suddenly jumps to 0 errors, verify it's not because a bad `.d.ts` replaced a package's types.
+
+**Current state (2026-03-27):** 31 errors, 0 warnings — all `ModalProps.children`.
+
+- [ ] **[flowbite-svelte] `ModalProps.children` — 31 errors across 26 files.** The flowbite-svelte
+  `Modal` component API changed; `children` is no longer a direct prop (now Svelte snippet-based).
+  Affected files span journals, pres_mgmt, events/settings, and IDAA archives.
+  Run `npx svelte-check 2>&1 | grep ModalProps` to get the current list.
+  Fix pattern: replace `children` prop binding with Svelte snippet syntax per flowbite-svelte docs.
+
+- [ ] **[package.json] Remove orphaned ShadCN/bits-ui packages.** `shadcn-svelte` and `bits-ui`
+  remain in `package.json` but have no usages — `src/lib/components/ui/` was removed 2026-03-27
+  (trashed to `~/tmp/gemini_trash/shadcn_components_ui_2026-03-27`). Safe to remove both packages
+  from `dependencies` when convenient.
