Phase 2 Plan 01: Flexible Sets — Dynamic setList, Add-Set Modal, Delete-Set Summary

ExerciseCard refactored to dynamic setList array with add-set bottom-sheet modal (Vanligt set / Dropset) and inline delete button with last-set guard

Performance

• Duration: ~8 min
• Started: 2026-02-21T00:00:00Z
• Completed: 2026-02-21T00:08:00Z
• Tasks: 2
• Files modified: 3

Accomplishments

• ExerciseCard state migrated from keyed setInputs object to ordered setList array — enables variable-length set lists
• Add-set bottom-sheet modal with two choices: Vanligt set (copies last row's weight/reps) and Dropset (3 sets at 100%/80%/60% weight rounded to 2.5kg, 10 reps)
• Per-row delete button with dual guard (disabled attribute + early return) prevents deleting the last remaining set
• Trash icon SVG added to Icons.jsx (outline style, consistent with existing library)
• All new interactive elements meet 44px minimum touch target requirement
• Build passes with no errors after both changes

Task Commits

Each task was committed atomically:

1. Task 1: Refactor ExerciseCard to dynamic setList + add-set modal + delete-set button - af80f16 (feat)
2. Task 2: Add CSS for modal overlay, add-set button, and delete-set button - 3d8a29c (feat)

Files Created/Modified

• frontend/src/pages/WorkoutPage.jsx - ExerciseCard fully refactored: setList state, handleAddNormal, handleAddDropset, handleDeleteSet, updated render with modal JSX
• frontend/src/components/Icons.jsx - Added trash SVG icon to Icons object
• frontend/src/App.css - Added 128 lines: .add-set-btn, .delete-set-btn (with disabled/hover states), .set-type-modal-overlay, .set-type-modal, .set-type-option, .set-type-option.dropset, .set-type-cancel

Decisions Made

• setList as array not object: Array index (idx) is the position; set_number is derived as idx+1 when calling onLogSet. Simpler than maintaining a keyed object when order matters for renumbering.
• Dropset percentages: 80% and 60% of base weight (20% drop per step), rounded to nearest 2.5kg — matches app's progression convention and research confirming 20% drops.
• CSS --bg-card over --surface: Plan used --surface which doesn't exist in the theme; --bg-card is the correct variable for card backgrounds.
• onDeleteSet as optional stub: Backend wiring (deleting orphaned set_number rows) is deferred to plan 02. The prop is accepted but only called if provided.

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Used --bg-card instead of nonexistent --surface CSS variable

• Found during: Task 2 (CSS addition)
• Issue: Plan specified var(--surface) and var(--surface-2) for modal background, but these variables do not exist in App.css; the app uses --bg-card and --bg-secondary
• Fix: Replaced var(--surface) with var(--bg-card) and var(--surface-2, rgba(255,255,255,0.05)) with var(--bg-secondary) in the modal CSS
• Files modified: frontend/src/App.css
• Verification: Build passes, variables resolve correctly in dark theme context
• Committed in: 3d8a29c (Task 2 commit)

---

Total deviations: 1 auto-fixed (Rule 1 - variable name correction) Impact on plan: Minor correction required for CSS to work correctly. No scope change.

Issues Encountered

None — build passed cleanly after each task. The CSS variable substitution was caught during Task 2 before committing.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• ExerciseCard now supports variable-length set lists entirely in frontend state
• Backend already persists sets by (exercise_id, set_number) via upsert — adding sets on frontend means next save includes correct sequence
• Plan 02 can wire onDeleteSet to call a DELETE /api/logs/:id endpoint to remove orphaned set_number rows from workout_logs when a set is deleted mid-workout
