Run 4 Session Log

Date: 2026-03-25 Branch: jmpicnic/uc-stories (ux-prototype) Checkpoint commit: 69228e4 (rebased onto base branch)

Summary

All tasks completed. 14 stories + 6 description.mdx delivered. Entity-media description finalized. Items.mdx updated with new entries. All gate checks pass post-rebase.

Execution

• 3 parallel agents (fe-set-image, fe-grid-remove, fe-ref-itm).
• ImageCellEditor blocker resolved: the fix was already on the base branch (picked up via rebase before Run 4 started). The entry check grep pattern was a false positive — stopEditing(true) on the cancel path is correct behavior, not the placeholder.

Design Notes

• happy-path.stories.tsx: Uses createUseCaseStories framework. Renamed FormData to ImageFormData to avoid collision with browser built-in.
• during-creation.stories.tsx: Vendored reference story imports from @/canary-refactor/components/ItemsPage + vendored CSS.
• during-creation-canary.stories.tsx: 100% canary with story-local simplified form (Input, Label, ImageFormField, Button).
• change-item-image/remove-item-image: 100% canary, full-app context using ItemGrid + ItemDetails.

Deviations from Plan

• ImageCellEditor entry check grep pattern (stopEditing.*true) produced a false positive. The pattern matches the legitimate cancel handler, not the placeholder. Recommend updating the check to grep for the specific placeholder comment or the useEffect(() => stopEditing pattern instead.
