SPORT::Basketball (SPOS.BKB)
= repeatable game-impact performance (skill × decision × athletic output × teamwork)
  across training + games + travel + congested schedules,
  while keeping knee/ankle/hamstring load below injury threshold.
Output is “reliable contribution” (efficiency + defense + availability),
not a single highlight game.

P3
- stable shooting mechanics under fatigue
- reliable decision speed (reads, spacing, rotations)
- repeated sprint + jump capacity without late-game collapse
- low injury time-loss; ankles/knees robust
- role clarity + team chemistry stable
P2
- good when fresh, inconsistent late
- shooting variance spikes with pressure
- defensive lapses under fatigue
- recurring ankle/knee soreness; load management inconsistent
P1
- frequent missed practices/games
- chronic joint pain or repeated sprains
- confidence swings; avoids contact/drive
- tactical confusion; turnover-prone under pressure
P0
- significant injury (ACL/meniscus/ankle instability), severe burnout
- cannot train/play reliably

Z0 sleep/fuel drift + Z1 game congestion
→ Z0 jump/landing fatigue + poor deceleration mechanics
→ Z0 ankle sprain or knee overload
→ Z2 missed sessions + loss of timing/shooting rhythm
→ P2 → P1 → P0 (injury cascade)
Repair: landing mechanics + load governance + shooting stability under fatigue.

TIMEFLOW::TEAM_COURT_FUNCTION
T0–T2: local team contests for cohesion + rivalry regulation (varied forms)
T3: codified indoor team sports emerge with schools/clubs (industrial city life)
T4: mass media leagues + global talent pipelines
T5: analytics + load governance + athlete health protocols

BKB::Primitives
PR0 Ball handling under pressure (protect, change pace)
PR1 Passing + decision reads (PnR, drive-kick, skip, extra pass)
PR2 Shooting mechanics (form stability; range extension safely)
PR3 Finishing through contact (footwork, touch)
PR4 Defensive stance + lateral speed + closeouts
PR5 Rebounding positioning + box-out habits
PR6 Jump + landing mechanics (knee/ankle safety)
PR7 Deceleration + change-of-direction braking strength
PR8 Conditioning: repeated sprints + quick recovery
PR9 Team cognition: spacing, rotations, communication

Z0::Top Failure Modes (Basketball)
FM0.B1 “pretty shot” breaks under fatigue/pressure
FM0.B2 weak handle → turnovers when pressed
FM0.B3 poor closeouts/rotations → defensive breakdown
FM0.B4 jump/landing asymmetry → knee/ankle risk
FM0.B5 repeated ankle sprains (no rehab, no stability work)
FM0.B6 overplaying (too many games) → tendon pain (patellar/Achilles)
FM0.B7 low strength base → cannot absorb contact/deceleration
FM0.B8 confidence collapse after misses → stops shooting / hesitates
Z0::Sensor Pack (Minimum viable)
S0.B1 minutes played + games/week (load)
S0.B2 jump/load proxy: soreness in patellar/Achilles + fatigue score
S0.B3 ankle stability status: wobble/balance test + sprain history
S0.B4 shooting variance: % in practice vs games; last-10-shot streaks
S0.B5 turnover triggers: when do turnovers happen? (press, left hand, fatigue)
S0.B6 defensive errors: missed rotations/closeouts count
S0.B7 recovery: sleep + mood/irritability
Z0::Repairs
R0.B1 shooting under fatigue: form cues + reps after conditioning
R0.B2 handle micro-dose daily: weak hand + pressure dribbles
R0.B3 defense habits: closeout angles + “early help” rules
R0.B4 landing mechanics: stick landings, knee tracking, decel drills
R0.B5 ankle prehab: balance + calf strength + proprioception; brace if needed
R0.B6 load cap: schedule rest + reduce extra pickup games
R0.B7 strength base: hinge/squat/single-leg + core bracing
R0.B8 confidence protocol: shoot the next one; 1 cue only

Z1::Failure Modes
FM1.B1 drills not representative (no speed/pressure/decision)
FM1.B2 too much scrimmage, too little skill foundation (or reverse)
FM1.B3 role confusion → hesitation + turnovers
FM1.B4 no load management during congested weeks
FM1.B5 poor injury return ladder (rushed return)
Z1::Sensors
S1.B1 practice-to-game transfer: do the same errors repeat?
S1.B2 shot quality rate (open vs contested) as a team proxy
S1.B3 defensive rotation breakdown frequency
S1.B4 fatigue indicators: late-game execution drop
S1.B5 injury recurrence rate post-return
Z1::Repairs
R1.B1 constraints-led practice: decision reps at game speed
R1.B2 role cards: 3 must-dos + 2 triggers + 1 no-go
R1.B3 simplify offense/defense rules (reduce cognitive load)
R1.B4 minutes caps + planned rest in congested weeks
R1.B5 return-to-play ladder with decel/jump gates

Z2::Failure Modes
FM2.B1 youth overuse: too many games, too little movement prep
FM2.B2 early selection bias; late bloomers lost
FM2.B3 no strength & landing mechanics program
FM2.B4 fragmented support (coach vs physio vs parents)
Z2::Sensors
S2.B1 games/season per athlete (youth caps needed)
S2.B2 ankle/knee injury days lost
S2.B3 dropout/burnout rate
S2.B4 skill progression: handle + shooting stability + defense IQ
Z2::Repairs
R2.B1 match budget + mandatory recovery windows
R2.B2 movement prep standard: landing/decel + strength base
R2.B3 integrated staff loop
R2.B4 late bloomer retention policy + development squads

Z3::Failure Modes
FM3.B1 congested fixtures + travel fatigue
FM3.B2 inconsistent officiating → unsafe contact
FM3.B3 incentives reward “play hurt” culture
Z3::Sensors
S3.B1 injury incidence around dense schedule windows
S3.B2 foul/unsafe contact trends
S3.B3 late-season performance collapses (fatigue signal)
Z3::Repairs
R3.B1 schedule caps + rest mandates
R3.B2 officiating calibration + safety enforcement
R3.B3 health-first return standards

STATE::BASKETBALL
- Load L = minutes played + practice intensity
- JumpStress JS = patellar/Achilles soreness trend + fatigue score
- AnkleRisk AR = stability test + sprain recurrence
- SkillStability SS = shooting form stability under fatigue + handle turnover triggers
- DecisionQuality DQ = turnovers + defensive rotation errors
- LateGame LG = last-5-min execution reliability
Phase Estimator:
IF SS stable AND AR low AND DQ improving AND LG stable → P3 drift
IF AR rising OR JS rising OR DQ worsening under fatigue → P2/P1 warning
IF injury causes repeated time-loss → P0 risk

1) identify break point: fatigue vs pressure vs speed
2) rebuild form with 1–2 cues only
3) add fatigue: shoot after sprints, keep cues constant
4) add pressure: consequences + time + contested reps
5) game transfer: define green-light shots + shot selection rules

Trigger: repeated sprains OR wobble instability OR fear of landing
1) rehab fully (ROM + strength + proprioception)
2) progressive return: straight-line → cuts → jumps → contact
3) landing/decel coaching (knee/hip alignment)
4) brace/tape during re-entry if needed
5) reduce extra play volume until stability returns

1) reduce early-game overexertion (pacing)
2) conditioning: repeated sprint + short recovery blocks
3) simplify decisions: 2 late-game actions only
4) free throws under fatigue training
5) recover: sleep + fueling + minutes governance

CivOS Link:
- Basketball is a “high-density coordination sport”:
  rapid decision, trust, role clarity, and conflict regulation under time pressure.
- Z4–Z5: talent pipeline + projection + community identity.
- Brittleness risk: overuse in youth + highlight culture + unsafe schedules.
- Repair: movement prep standards + load governance + safeguarding.
