Session Reliability + Execution Timing + Testing Foundations

Shipped

• Session reliability

  • Added session expiry helpers (TTL + last-activity detection)
  • Improved active session management and localStorage synchronization
  • Added clearer user feedback when sessions expire or desync

• Better workout execution data

  • Added per-exercise timing fields (started_at, ended_at, duration_seconds) in workout executions
  • Introduced hooks/utilities to manage exercise timing consistently
  • Added metadata for timer states and manual duration overrides (with reasons)

• Quick workout upgrades

  • Added new setup steps for bands + duration selection
  • Improved TimerHeader controls (e.g., tracking failed reps via dropdown)
  • Expanded supporting UI components for a more coherent setup flow

• Testing system (big reliability win)

  • Added Playwright (dev dependency) and created a demo smoke test suite for core flows
  • Introduced combined test commands for unit + smoke tests
  • Added deterministic seed strategy using a synthetic export bundle
  • Expanded testing/debugging documentation and agent commands to keep QA repeatable

• Equipment + mapping

  • Added settings/management pages for band and dumbbell equipment
  • Implemented routine band mapping dialog for shared routines

Why

• Reliable sessions prevent “lost workouts” and reduce user anxiety during training
• Timing + overrides make conditioning and interval work measurable and auditable
• Deterministic smoke tests protect demo-worthiness and prevent regressions as the engine expands

Notes

• This release strengthens the foundation for non-lifting modalities (time-based work, intervals, conditioning).

Next

• Continue tightening the workout player UX around timing and intervals
• Expand test coverage to builder flows and draft recovery
