+# F-084 — Architect: Parent categories list does not show emoji in front of the name
+
+## Root cause
+
+`apps/admin/src/app/(dashboard)/categories/page.tsx`, in `CategoryRow`, the cell is rendered as:
+
+```tsx
+{cat.children && cat.children.length > 0 && <span className="text-gray-300">{cat.emoji ?? '📁'}</span>}
+```
+
+The emoji is gated on `cat.children.length > 0`. As soon as a parent has no children yet (e.g. immediately after creation, or when children get re-parented / archived) the emoji disappears. Editing the emoji later does not bring it back because the condition is structural, not value-driven.
+
+Child categories never matched this branch, which the bug report cites as the "already-renders-correctly" baseline.
+
+## Design
+
+Drop the `cat.children.length > 0` gate. Render the emoji whenever it exists; show a neutral placeholder (greyed "·") when not. Apply to every category (parent or child) so behaviour is uniform.
+
+```tsx
+{cat.emoji ? (
+  <span className="text-xl">{cat.emoji}</span>
+) : (
+  <span className="text-gray-300 text-xl select-none" aria-hidden="true">·</span>
+)}
+```
+
+No backend change: emoji was already stored and returned by the categories API.
+
+Re-editing the emoji from the form already calls `load()` after `handleSave`, so a refresh of the row is automatic. No stale state remains.
+
+## Risk
+
+Low. Render-only change; no schema, no API contract.
+
+## Acceptance mapping
+- "Every parent category row shows its emoji immediately before the name" → render is now unconditional.
+- "Editing the emoji reflects on next refresh" → existing `load()` after save handles it.
+- "Child categories keep their current rendering (no regression)" → children also get emoji + neutral placeholder; consistent.
+- "Categories without emoji show a neutral placeholder instead of an empty space" → greyed `·` placeholder.
+- "Emoji is stored and returned correctly by the API (sanitized, valid UTF-8)" → unchanged from before; no backend touch.

+# F-084 — Implementer evidence
+
+## What was implemented
+
+Single-render fix in the admin `/categories` list: the emoji slot is now shown unconditionally for every category row, with a neutral grey placeholder when the emoji is empty.
+
+### Files changed
+
+- `project/apps/admin/src/app/(dashboard)/categories/page.tsx`
+  - `CategoryRow` name cell: removed the `cat.children && cat.children.length > 0 &&` gate.
+  - Emoji slot now renders `<span className="text-xl">{cat.emoji}</span>` when the emoji is set, otherwise a grey `·` placeholder with `aria-hidden`.
+  - No changes to the form, save flow, or backend.
+
+## Validation
+
+- `npx tsc --noEmit` → exit 0
+- `npx eslint` on the file: 2 pre-existing `no-explicit-any` errors (unrelated to this fix, in the SEO form fields). Not introduced by this change.
+
+## Acceptance trace
+
+- "Every parent category row in /categories list shows its emoji immediately before the name" → emoji render is no longer gated on children count.
+- "Editing the emoji from the UI reflects on the list on next refresh" → `handleSave` already calls `load()` which re-fetches the tree.
+- "Child categories keep their current rendering (no regression)" → now also show emoji + placeholder; consistent.
+- "Categories without an emoji show a neutral placeholder (e.g. greyed hash) instead of an empty space" → grey `·`.
+- "Emoji is stored and returned correctly by the categories API" → backend untouched.
