SPORT::Athletics::Jumps (SPOS.ATH.JMP)
= repeatable jump performance (approach speed × takeoff mechanics × air control × landing reliability)
  across training blocks and competition days,
  while keeping Achilles/knee/ankle/hip load below injury threshold.
Output is “approach + takeoff consistency at high speed” + “availability”.

P3
- approach rhythm consistent; takeoff hits board/mark reliably
- takeoff mechanics stable at speed; minimal braking
- elastic/tendon load governed; few flare-ups
- competition composure: fouls and misses controlled
- strength/plyo integrated without overload
P2
- good jumps on good days, inconsistent on others
- approach variability; fouls common
- Achilles/patellar soreness recurring
- takeoff mechanics degrade under fatigue; braking increases
P1
- frequent missed sessions due to tendon/joint pain
- fear on takeoff; reduced approach speed
- skill regression; performance variance high
- repeated fouls; competition confidence drops
P0
- significant injury (Achilles, patellar tendon, ankle, knee/hip)
- cannot train/compete reliably

Z1 plyometric + approach-speed load spike
→ Z0 Achilles/patellar tendon irritation
→ Z0 approach speed reduced (fear) → mechanics degrade → more stress
→ Z2 missed sessions + loss of rhythm
→ P2 → P1 → P0 (tendon injury)
Repair: reduce plyo/intensity, rebuild approach rhythm, reintroduce speed and takeoffs with strict caps.

TIMEFLOW::JUMP_FUNCTION
T0 survival: leaping gaps, climbing, vaulting obstacles
T1 ancient civilisations: warrior agility displays; festival contests of power
T2 pre-modern: folk games + martial readiness
T3 industrial: standardized track & field events, clubs, measurement/records
T4 modern: elite biomechanics + national projection
T5 sensor era: approach-speed tracking + tendon load governance + individualized plyometric dosing

Z0::Top Failure Modes (Jumps)
FM0.J1 approach inconsistency → fouls or poor takeoff distance
FM0.J2 chasing speed without rhythm → braking + injury risk
FM0.J3 too many takeoffs/plyos per week (tendon overload)
FM0.J4 weak single-leg strength → knee collapse at takeoff
FM0.J5 poor penultimate step mechanics
FM0.J6 Achilles/patellar soreness ignored → chronic tendinopathy
FM0.J7 fear after bad landing → reduced speed + worse mechanics
FM0.J8 no competition routine → fouls, rushed cues

S0.J4 tendon pain map: Achilles/patellar/ankle/hip (0–10) + morning stiffness
S0.J5 approach speed proxy (timed last 10m) occasional

STATE::JUMPS
- ApproachConsistency AC = mark/board hit-rate
- TakeoffDose TD = hard takeoffs/week + plyo proxy
- TendonRisk TR = Achilles/patellar pain + morning stiffness trend
- Mechanics M = penultimate/takeoff video score
- Speed S = approach speed proxy trend
- CompReliability CR = foul rate + best-jump stability
Phase Estimator:
IF AC high AND TR low AND TD controlled AND S stable → P3 drift
IF TR rising OR AC dropping OR foul rate rising → P2/P1 warning
IF tendon injury stops jumping → P0 risk

1) shorten approach until mark hit-rate ≥ threshold (e.g., 80–90%)
2) rebuild rhythm with consistent checkmarks
3) gradually extend approach length while preserving hit-rate
4) add speed only after rhythm is stable
5) competition routine locked (same steps, same cue)

Trigger: morning stiffness or pain trend rising >7 days
1) reduce takeoff/plyo dose immediately
2) tendon loading protocol (isometrics → eccentrics → plyo re-entry)
3) strengthen single-leg stiffness and calf capacity
4) reintroduce takeoffs with caps + rest days
5) audit spikes: too many full approaches, hard surfaces, poor recovery

1) drop to short approach + soft landings
2) rebuild successful reps (confidence)
3) add progression: short → medium → full
4) reintroduce speed last
5) keep cue simple: “tall + quick” (example), avoid overthinking

CivOS Link:
- Jumps are “speed-to-power conversion” showcases:
  they translate sprint capability into controlled explosive output.
- Brittleness risk: load spikes + tendon fragility + PR hunting culture.
- Repair: strict takeoff-dose governance, progression gates, and tendon health standards.
