Sculpi. F1–F3 on screen

1 · The hub. §18 sequence, three honest states

One BEFORE for reference, then the hub after F1–F3 in its three states. Walks are always first - free movement never waits behind a plan. Today always answers the question: a session to start, or an explicit rest day with the next date.

§18.1 Quick movement first, steps live in the header, not as a card Walk types as small cards in a horizontal scroll, tap a star ★ to pin a favorite Order: starred first (most-used among them), then the rest by most-used Today never disappears, rest days say “No session today” + the next date (amends §18.2) My programs card = cover + gradient with name, level, days and progress; tap opens the program detail (§18.3) §18.4 sessions live inside the program detail, no loose ×N cards Never: pending · overdue · behind

Today card: plan + session name only, no “session 2 of 4”, it doesn’t scale to a 3-month plan. The program card is its cover image with a black→transparent bottom gradient, name, level and progress drawn on top; vanity numbers moved to the program detail (tap the card). Explore is a horizontal shelf of available plans; “See all” opens the full vertical catalog with categories, filters and sorting (screen in the destination page; the shelf renders whatever validated content exists, v1 ships VitalPath).

MentorSport · Beginner · Up next: Strength 3. Friday

Rest day is explicit. Today never disappears: it says “No session today” and gives the next date (amends §18.2’s “omit Today”). “Do it today” to train ahead arrives with F5’s management UI.

2 · Inside the program, tap the card, see the whole sequence

Tapping the My programs card opens the program detail: progress, vanity numbers, upcoming sessions and the previous ones with their dates. Session rows open the workout detail, and completion now follows the sequence: only the current session can be marked done; locked ones stay watchable.

§9.2 session 3 can’t happen before session 2 is resolved Completion is atomic: ledger + streak + unlock next, one transaction Copy is neutral, locked, not “overdue”

Watching is free; tracking needs a program. Walks remain the no-strings option, always on top of the hub.

3 · A real ending, programs are finite

Today, finishing Strength 4 silently loops back to Strength 1, forever. After F1–F3 the enrollment completes, the moment is acknowledged, and doing it again is an explicit fresh cycle (§9.9), history intact.

Principle 6: plans never repeat automatically Celebrates sessions shown up, never weight

5 · Under the hood, what you won’t see, but everything rests on

Most of F1–F3 is invisible on purpose. This is what exists after this batch; the F4–F6 screens will simply render it.

Your history migrates, nothing is lost

Existing workout entries are partitioned into finite cycles, example with 9 past completions:

Cycle 14/4 · completed → Cycle 24/4 · completed → ActiveS1 ✓ · S2 current

Out-of-order entries stay as plain history, migration never invents progress. Idempotent: running twice changes nothing.

One current session, always

The chain the UI renders directly:

S1completed → S2skipped → S3current · waiting → S4locked · Mon

Complete or skip advances exactly one. Skip never pulls the next session to today. Locked dates reflow as one chain.

Versioned content with muscles

All 36 VitalPath exercises get a validated catalog: movement pattern, laterality, per-muscle volume allocation (always 100%), curated swap rules, authored rest. It powers the F6 runner, swaps and F8 analytics with no rewrite.

Streaks, reminders and parity keep working

Completing a session emits the same daily-consistency event; the single training-day reminder still respects the one-per-day cap. Engine behavior is pinned by ~16 platform-neutral fixture files that Android replays verbatim when it mirrors this milestone.
