SPORT::Football (SPOS.FTB)
= repeatable match performance (technical skill × decision speed × physical output × tactical role execution × team synchronization)
  across fixtures and seasons,
  while keeping soft-tissue injury risk (hamstring/groin/ankle/knee) below threshold.
Output is “match impact + role reliability + availability”.

P3
- reliable technical execution under pressure (first touch, passing, finishing)
- high-intensity running capacity stable; recovers between games
- tactical role execution consistent (pressing triggers, spacing)
- hamstring/groin/ankle injuries contained; minimal time-loss
- team coordination stable (press, rest defense, transitions)
P2
- good halves and bad halves; inconsistent intensity
- technical errors rise under fatigue
- hamstring/groin tightness recurring; small knocks accumulate
- tactical timing drifts (late presses, broken lines)
P1
- frequent missed sessions due to soft-tissue injuries
- reduced sprinting; cautious play
- repeated tactical breakdowns; confidence drops
- performance variance high across matches
P0
- major injury or chronic recurring injuries/burnout
- cannot train/compete reliably

Z3 congested fixtures + Z0 sleep/fueling drift
→ Z0 fatigue debt + sprint mechanics degrade
→ Z0 hamstring/groin overload
→ Z1 tactical timing slows (late presses) → more chasing load
→ P2 → P1 → P0 (soft-tissue injury cascade)
Repair: running-load governance + sprint exposure management + role simplification + recovery buffers.

Z0::Top Failure Modes (Football)
FM0.FB1 poor first touch under pressure → turnover load increases
FM0.FB2 sprint exposure too low then sudden spike → hamstring risk
FM0.FB3 groin pain from inadequate adductor strength (change of direction)
FM0.FB4 fatigue → late tackles + knocks
FM0.FB5 poor tactical understanding → unnecessary running
FM0.FB6 weak decel mechanics → knee/ankle overload

Z0::Sensor Pack (Minimum viable)
S0.FB1 running load: total distance + high-speed runs (proxy) per week

R0.FB7 fueling baseline: carbs around training + protein after
R0.FB8 discipline routine: breath + reset + role-first focus

Z1::Failure Modes
FM1.FB1 training load mismatched to fixtures (no taper)
FM1.FB2 pressing system too complex → chaos and over-running
FM1.FB3 insufficient sprint exposure in training → injuries in matches

STATE::FOOTBALL
- Load L = weekly distance + high-speed efforts proxy
- SprintExposure SE = true fast runs/week
- SoftTissueRisk STR = hamstring/groin pain + stiffness trend
- TechUnderPressure TUP = late-game technical errors
- TacticalExec TE = missed triggers + spacing breakdowns
- Recovery Rec = sleep + fatigue trend
- Discipline D = cards/fouls + tilt indicators
Phase Estimator:
IF L governed AND SE stable AND STR low AND TE improving → P3 drift
IF STR rising OR SE spikes OR TE collapses under fatigue → P2/P1 warning
IF recurring injuries stop play → P0 risk

Trigger: tightness trend rising OR soreness persists next day
1) reduce high-speed load immediately; avoid max sprints
2) strengthen: hamstring eccentrics + adductors + hip stability
3) maintain fitness via low-impact conditioning (bike/pool)
4) return ladder: submax runs → controlled fast → match-speed
5) enforce sprint exposure standards to prevent future spikes

1) diagnose: why are players chasing? role ambiguity? spacing?
2) simplify triggers and rest-defense rules
3) train compactness and transition cues
4) measure: reduce unnecessary high-speed runs while improving control
5) reintroduce complexity only after stability

1) improve aerobic base + RSA (repeat sprint ability)
2) add fatigue-proof technical drills (first touch/passing under pressure late)
3) stabilize decision rules (safe options when tired)
4) improve recovery and matchday+1 protocol
5) monitor: late-game error count trend should fall

CivOS Link:
- Football is “high-coupling swarm coordination”:
  it reveals how shared cues and role clarity reduce load and prevent drift.
- Brittleness risk: fixture congestion + tactical confusion → running overload → soft-tissue P0 events.
- Repair: load governance, sprint exposure standards, and tactical compression.
