Development here follows Gagné-like honesty: aptitudes, practice and catalysts. Athletic talent is not a finished essence.
Windows differ by domain. A closed sport window is not a closed writing window. Read the clocks.

Ethics.
Levers
- Coach design — The scarce hour.
- Sampling vs specialising — Sport-dependent.
- Health system — Injuries end files.
- Who is invited — ID access.
- Place — Iten-type environments — named as places.
Windows
- Early play — Bloom phase one.
- Puberty / growth — A dangerous ID moment.
- Event-specific peaks — Gymnastics ≠ marathon.
- Adult codes — Some sports recruit late.
Supports
- AIS-type institutes — Science plus ID.
- Club academies — Brazil/Europe pipes.
- School sport (部活, Title IX) — Hours as policy.
- Community first-contact — Before the harvest.
Athletic talent: catalysts and windows do the daily work. Destiny talk is the failure mode.
