Workout notes: pre, side, and post

Three kinds of notes

Every scheduled workout has three note sections, designed to match the workout's lifecycle:

Pre-execution / about: written before the workout. Instructions, context, what the athlete should focus on.
Side notes: general observations that do not fit pre / post cleanly. Conditions, equipment changes, anything mid-stream.
Post-workout: written after the session. How it went, RPE, lessons.

Athletes (free or premium) and coaches can post in any thread.

Defaults for visibility

Athlete-authored notes: always visible to the athlete (they wrote them) and always visible to the coach.
Coach-authored notes: default to hidden from athlete. The coach can flip the "Visible to athlete" checkbox when posting to make a note visible.

This mirrors the existing CoachNote privacy pattern: coach private working notes stay private by default; coach notes meant for the athlete are opted into visibility.

Who can see what

Viewer	Sees
Coach (current relationship)	All notes on workouts for their roster athletes
Premium athlete (own)	Own notes + coach notes flagged visible
Free athlete (own)	Own notes + coach notes flagged visible
Free athlete (own)	Own notes + coach notes flagged visible (can post)
Other coaches	No access (relationship gate)
Admins	All notes

How to post

On the workout detail page, scroll to the three sections. Each has an inline form: type, optionally toggle "Visible to athlete" (coach only), click Post note.

Limits

5000 characters per note.
No file attachments (Phase 2 if needed).
No threading within a section (notes are flat; the sections themselves are the structure).
No edit-in-place; delete and re-post if you typo.

Free athletes

Free athletes can read notes (subject to the visibility gate) and can post notes on their own workouts. Posting a note is allowed even though free athletes cannot create, edit, or drag-move the workouts themselves.

What notes are good for

Pre: "Skip the second 20 if heat is brutal", "Use the TT bike", "Try a new gel here".
Side: "Wind was punishing today, did the second half indoors", "Saddle felt off post-fit".
Post: "Felt great through the second interval, third was rough", "GI issues after gel #3, swap brand next time".

For structured coach-only observations (limiters, season strategy, hidden interpretation), use a regular CoachNote on the athlete record instead. Workout notes are about this session.
