🧠 Context / Focus for Today
Stabilize the Garmin export pipeline end-to-end, confirm reliable planned workout delivery, and reduce uncertainty around Garmin sync behavior before shifting focus to AI model experimentation.
✔️ Things I Got Done Today
Garmin Export Pipeline
- Successfully pushed a planned workout to Garmin Connect via the Training API.
- Confirmed the workout:
- Appears correctly in Garmin Connect
- Syncs to the user's device as expected
- Validated that:
- Workout discovery logic is functioning correctly
- Planned vs completed workout branching behaves as intended
- Permissions and OAuth scopes are valid and sufficient
- Reduced the remaining risk surface to edge cases rather than core delivery.
Codebase Hardening
- Reviewed the Garmin export path to ensure it is:
- Deterministic
- Observable via structured logging
- Cleanly separated from UI concerns
- Identified specific follow-ups where additional validation or error messaging will improve debuggability.
Execution Discipline
- Kept scope tightly focused on Garmin reliability, explicitly deferring non-essential features.
- Re-affirmed sequencing:
- Garmin push reliability first
- AI model testing and plan generation second
- Avoided introducing new systems during a critical stabilization phase.
🚧 In Progress
- Hardening export error handling for edge cases.
- Validating planned workout pushes across multiple workout types.
- Final cleanup and confidence checks before declaring Garmin push "stable."
🎯 Targets for Tomorrow
- Validate Garmin planned workout pushes across additional scenarios.
- Add final guardrails and logging to lock in reliability.
- Decide whether the Garmin push pipeline is stable enough to shift focus to AI model testing.
- Keep all work execution-focused; no roadmap expansion.
🤔 Notes / Observations
- Achieving a successful planned workout push is a major milestone.
- Remaining work is now about confidence and coverage, not core feasibility.
- Garmin reliability progress feels real and cumulative.
📈 Momentum Score: 8.8 / 10
Breakthrough day. Core Garmin push workflow is now proven end-to-end.
