Treadmill Session Replay and Reporting
Use this skill when the task involves:
- session replay screens
- timeline scrubbing
- stage overlays
- event markers
- report generation
- longitudinal athlete comparisons
- printable summaries
- export-friendly metric views
Objective
Make sessions reviewable, coach-friendly, and faithful to the data actually collected.
Replay and reporting should preserve:
- treadmill protocol stages
- speed and incline changes
- operator notes
- manual event markers
- confidence context
- signal quality context
- inferred-motion warnings when applicable
Replay rules
Replay should:
- stay aligned to session time
- show protocol stage transitions clearly
- show event markers such as shoe change or fatigue onset
- support chart overlays
- preserve data gaps and degraded periods rather than hiding them
Report rules
Reports should:
- summarize the session and each stage
- compare to prior sessions when available
- note calibration and signal quality context
- show confidence for important outputs
- explicitly mark inferred-motion outputs as synthetic and model-based
- avoid overclaiming certainty
Product language
Prefer:
- session summary
- stage summary
- estimated metric
- proxy metric
- inferred motion rendering
- validation status
- confidence summary
Avoid:
- definitive diagnosis
- exact mechanics unless validated
- true camera replay
Always update
When using this skill, review:
- apps/web replay and reports pages
- backend report metadata and APIs
- docs/validation_workflow.md
- docs/inferred_views.md
- tests for replay timelines and report disclaimers
