Build Log – 2025-12-10

📅 Daily Log — 2025-12-10

🧠 Context / Focus for Today

  • Fix the red-file bug in /api/debug/planning/garmin/route.ts.
  • Understand the true purpose of the Garmin → Planning board automations.
  • Prepare the foundation for FIT Export threads.
  • Create a /blog section to publish daily logs and build in public.

✔️ Things I Got Done Today

🏃‍♂️ Product / Training

  • Revisited triathlon cadence strategy: why a 90–95 rpm cadence can help preserve run legs by reducing muscular load vs torque-heavy cycling.

💻 Flow State Codebase

  • Fixed bugs in the Garmin planning debug endpoint:

    • Correctly moves “Harden Garmin date-range chunking + dedupe” to Done.
    • Correctly upserts “Harden Garmin webhook delivery, validation, and replay handling” into Planned.
    • Resolved the issue where the file was showing as “red” in Cursor — folder or TypeScript issues resolved.

  • Clarified what the endpoint actually does:

    • It’s a small automation tool to complete one Garmin reliability milestone and automatically seed the next one.
    • Useful for structured progression of reliability work.

  • Started planning the groundwork for FIT Export implementation:

    • Confirmed purpose: generate structured workouts → FIT so Garmin Connect can sync them to devices.
    • Discussed unified JSON schema for RUN + BIKE with warmup/steps/cooldown.

🐛 Debugging / Fixes

  • Confirmed the planning debug endpoint now behaves correctly end-to-end.
  • Identified UX issues (popups cut off, skeleton layout flashing) and gathered Cursor prompts to fix them later today or tomorrow.

🧱 Architecture / Planning

  • Revisited how /planning and debug endpoints integrate with the upcoming FIT export tasks.
  • Simplified strategy: start a brand new Cursor thread for FIT export so history noise doesn’t slow Cursor down.
  • Decided on Option A for /blog:
    • Static MDX posts in /app/blog/posts
    • Very low maintenance
    • Perfect for build logs + documenting progress publicly

⚙️ DevOps / Tooling

  • Clarified how to log into the project from Cursor on another laptop.
  • Understood SSH’s role in Cursor’s repo connectivity.
  • Prepared Cursor prompts for:
    • /blog route scaffolding
    • Adding nav link (“Build Log”)
    • Creating first post (2025-12-09.mdx)
  • Confirmed Option A is manual but extremely light-weight, ~10–20 seconds per daily post.

🧩 Misc

  • Built clear mental structure for:
    • How Garmin reliability tasks flow
    • Why the debug endpoint exists
    • How daily logs will now exist inside the codebase

🚧 In Progress

  • Implementing /blog (static MDX) using the Cursor prompt.
  • Preparing FIT Export thread with full context and example .fit file placement.
  • Cleaning lingering UI issues (popup cutoff, loading skeleton visibility).

🎯 Targets for Tomorrow

  1. Kick off the FIT Export implementation with unified workout schema and example FIT file tests.
  2. Verify the /blog route renders correctly and publish logs going forward.
  3. Continue Garmin reliability improvements (webhook validation + replay handling).

🤔 Notes / Observations

  • The planning debug endpoint has a clearer purpose now — it’s not just “move tasks,” it’s evolving the Garmin reliability roadmap.
  • Creating a /blog is actually very low overhead and centralizes progress tracking.
  • Cursor prompts were effective after scoping them properly.

📈 Momentum Score (0–10)

8/10 — Strong clarity today; foundational automation and documentation are becoming more structured. Tomorrow’s FIT export kickoff will mark a major milestone.
