 ### Phase 5: Files
 **Goal:** A user can attach files to a tablo, list them, download them via signed URLs, and delete them — backed by S3-compatible storage.

+## Summary
+
+Human verification checkpoint for Phase 4 kanban board. Automated suite gate passed (5 packages, all ok). Two bugs surfaced during browser testing and fixed before approval.
+
+## What was verified
+
+All 7 TASK requirements confirmed working in a live browser session:
+- TASK-01: 4 kanban columns render with correct labels and count badges
+- TASK-02: Task creation via inline form (no page reload), card appears in correct column
+- TASK-03: Inline task editing — click card, edit form pre-filled, save updates title
+- TASK-04: Cross-column drag-and-drop via ⠿ handle, persists after reload
+- TASK-05: Within-column reorder via drag, persists after reload
+- TASK-06: Delete with confirmation step, card removed on confirm
+- TASK-07: Order survives full page reload (covered by TASK-04/05 reload checks)
+
+## Bugs found and fixed
+
+### Bug 1 — Badge count not updating on task create/delete
+Badge count was rendered server-side at page load only. Added `id="task-count-badge-{status}"` wrapper to each column header badge and a `updateBadges()` function triggered on `htmx:afterSettle` to recount `.task-card` elements. Commit: `68f2ccd`.
+
+### Bug 2 — Drag-and-drop not working
+`draggable: ".task-card"` was incorrect — `.task-card` is a grandchild of `.sortable-column` (nested inside `.task-card-zone`), so Sortable was detaching the inner card from its wrapper during drag, breaking HTMX OOB swap targets. Changed to `draggable: ".task-card-zone"` so Sortable moves the full wrapper. Also replaced `htmx.onLoad()` (requires htmx defined at parse time) with native `document.addEventListener('DOMContentLoaded')` + `htmx:afterSettle`. Commits: `68f2ccd`, `131c9fd`.
