     `/lab` shows a **"Your Lab profiles"** strip. `main.tsx`'s clean-link shim now
     also rewrites `/coach/<pubkey>/<d>`. Still open: draft/autosave and a
     multi-step layout.
+  - **Lab offer form polish (2026-10-04, part 2):** four more gaps closed.
+    **Drafts:** `hooks/useLabDraft` autosaves the form snapshot to localStorage
+    (content-debounced) and only offers it as resumable when it *differs* from the
+    current state (so opening an existing profile never shows a spurious banner
+    and a draft can't clobber a fresh load); `LabDraftBanner` gives Resume /
+    Discard; clears on publish. **Progress:** `LabProfileProgress` is a
+    completeness bar (photo/bio/skills/rate/location/contact) — a progress
+    indicator, not a wizard. **Validation:** `CraftProfileForm` + the coach page
+    split contact validation into per-field inline errors (+ red border) and
+    **scroll to the first invalid field / the skills grid** on submit; required
+    skill sections show an inline message after a submit attempt. **URLs:** Lab
+    profiles now live at **`/lab/<craft>/<pubkey>/<id>`** (`lib/labRoutes.ts`
+    builds it; `/coach/...` still resolves). The bespoke pages have inline contact
+    errors but not the scroll-to behavior (yet).
   - **Photos**: `PhotoDropzone` (`src/components/PhotoDropzone.tsx`) is the shared
     image input — **drag & drop + multi-select**, emits `File[]` to its caller
     (which owns uploads/toasts). Used by `CreateSpotPage`, `EditSpotPage` and
