Depends on the four-pillar measurement work landing first — a dashboard over measures that do not exist yet would be inventing numbers, which Setline refuses to do everywhere else.
Four-pillar dashboard
Weekly dose against target and a trend per pillar. Swift Charts for estimated 1RM, tonnage per muscle group, range of motion, pace and zone distribution. Honest empty states throughout: no evidence means no chart.
On-device generation
SystemLanguageModel with @Generable guided output producing a structured block, then validated by a deterministic checker before anything is written — equipment actually available, weekly volume sane, rest ranges legal, progression rules coherent. Two uses:
- Natural-language authoring: "40-minute push day, no barbell"
- Free-text plan import: paste a programme, get a structured block
Gated on SystemLanguageModel.default.availability. Devices without Apple Intelligence fall back to the rule-based generator, which exists regardless — progression logic must stay deterministic, and a model must never be the thing that decides a load.
watchOS companion
Session player on the wrist, live heart rate during cardio, haptic rest and interval alerts, syncing through the shared CloudKit container. Depends on iCloud sync landing.
Verification
Generated blocks must pass the deterministic validator in tests. Chart empty states verified in simulator. A Watch session must complete and merge on real hardware.
