# Project State

## Project Reference

See: .planning/PROJECT.md (updated 2026-02-15)

**Core value:** Logging a workout should be fast, clear, and flexible — the app never fights the user during a session
**Current focus:** Phase 1 — Input UX

## Current Position

Phase: 2 of 3 (Flexible Sets)
Plan: 1 of 2 in current phase (02-01 complete)
Status: Phase 2 in progress — plan 02-01 done, 02-02 pending
Last activity: 2026-02-21 — Completed 02-01 (ExerciseCard dynamic setList, add-set modal, delete-set)

Progress: [█████░░░░░] 50%

## Performance Metrics

**Velocity:**
- Total plans completed: 3
- Average duration: ~1.3 min
- Total execution time: ~0.07 hours

**By Phase:**

| Phase | Plans | Total | Avg/Plan |
|-------|-------|-------|----------|
| 01-input-ux | 3/3 | ~4 min | ~1.3 min |
| 02-flexible-sets | 1/2 | ~8 min | ~8 min |

**Recent Trend:**
- Last 5 plans: 01-01 (1 min), 01-03 (2 min), 01-02 (1 min), 02-01 (8 min)
- Trend: fast

## Accumulated Context

### Decisions

- Keep existing program model; custom workouts are a fork, not a replacement
- Frontend-only changes for Phase 1 (zero backend risk)
- React Hook Form + Zod approved for input validation (research recommendation)
- Do NOT modify shared program data — fork to custom_workout table for per-user changes
- StepperInput is a pure controlled component — no internal useState, all state lives in parent
- 44px minimum touch targets on stepper buttons for mobile usability; 16px font prevents iOS auto-zoom
- Decimal step (2.5) uses inputMode=decimal; integer step uses inputMode=numeric
- All App.css interactive elements have min-height: 44px; global input font-size: 16px prevents iOS auto-zoom across all form fields
- handleInputChange already accepts plain string values — WeightInput/RepsInput onChange passes string directly, no signature changes needed
- flex-start alignment on .set-row and .set-inputs accommodates taller stepper containers
- setList uses array index (not set_number key) — set_number derived as idx+1 when calling onLogSet
- Dropset weight drops: 80% then 60% of base weight, each rounded to nearest 2.5kg per app progression convention
- Last-set guard: handleDeleteSet returns early if setList.length <= 1, delete button also disabled in DOM
- progress-badge and all-done class reference setList.length instead of exercise.sets — badge reflects actual set count
- onDeleteSet prop is optional stub in ExerciseCard — backend wiring deferred to plan 02-02

### Pending Todos

None yet.

### Blockers/Concerns

- Phase 3 requires new DB tables (custom_workouts, custom_workout_exercises) and a source_type column on workout_logs — backend schema migration needed before Phase 3 planning
