Tuning knobs for the 4.0 pipeline, env-driven server-side.

Fields

grade_unit_bond: f64

Raw score per grade step on the bond axes (AFFINITY_GRADE_UNIT_BOND). The 2.96× spread between the two units is the judge’s measured grading asymmetry (tension reaches grade ≥2 on ~half of turns, trust is graded 0 on ~80%), written down where it can be argued with.

grade_unit_chem: f64

Raw score per grade step on the chemistry axes (AFFINITY_GRADE_UNIT_CHEM).

neg_factor: f64

Extra multiplier on negative raw scores (AFFINITY_NEG_FACTOR) — keeps 2.0’s “slow up, fast down” asymmetry.

tier_decay: [f64; 5]

Positive-delta damping per tier 1..=5 (AFFINITY_TIER_DECAY).

cross_penalty_ratio: f64

Cross-line penalty ceiling as a multiple of the line’s unit (AFFINITY_CROSS_PENALTY_RATIO): κ_line = ratio · u_line. Tying κ to the unit makes the double-high break-even independent of the unit — per-line units would otherwise silently move the wall.

cross_penalty_start: f64

Counterpart line score where the penalty starts (AFFINITY_CROSS_PENALTY_START).

delta_threshold: f64

Commit threshold θ (AFFINITY_DELTA_THRESHOLD); 0 commits every turn.

demo_boost: f64

Multiplier on the judge’s positive raw component for demo sessions (AFFINITY_DEMO_BOOST); rule nudges are unaffected.

floor_ratio: f64

Endpoint floor ratio φ (AFFINITY_FLOOR_RATIO): a level-1 verdict reads φ·counterpart instead of 0. Must stay ≤ 0.24 so the floor can never touch a level-2 verdict (1/3·B(0) ≈ 0.2436).

time_decay_rate: f64

Endpoint absence decay per day (AFFINITY_TIME_DECAY_RATE).

time_decay_floor: f64

Endpoint absence decay floor (AFFINITY_TIME_DECAY_FLOOR).
