#           or ROLLING_WINDOW_SIZE=2048 (smaller for memory constraints)
#   - System AUTOMATICALLY shrinks during execution if diminishing returns detected
#   - Window starts conservative, self-tunes down if pattern diversity plateaus
#   - Window becomes "warm" (representative) after N executions, then adapts
$(eval $(call kconfig_int,ROLLING_WINDOW_SIZE,4096))

#   - Default: 8 (see starforth_config.h for the exact shipped value)

# ============================================================================
# These control how aggressively the rolling window learns and adapts

# Knob #8: ADAPTIVE_SHRINK_RATE (percentage to retain when shrinking)
#   - Default: 50 (shrink to 50% = discard 50% each cycle)
#   - Range: 50-95 (lower = more aggressive, higher = more conservative)
#   - Usage: make ADAPTIVE_SHRINK_RATE=75 (slower learning) or 90 (slow learning)
$(eval $(call kconfig_int,ADAPTIVE_SHRINK_RATE,50))

# Knob #9: ADAPTIVE_MIN_WINDOW_SIZE (floor to prevent over-shrinking)
#   - Default: 256 (never shrink below 256 word IDs)
#   - Range: 64-1024 (smaller = leaner, larger = safer)

# Knob #10: ADAPTIVE_CHECK_FREQUENCY (how often to measure diversity)
#   - Default: 512 (check after every 512 executions)
#   - Range: 32-1024 (more = faster response, less = less overhead)
#   - Usage: make ADAPTIVE_CHECK_FREQUENCY=128 (responsive) or 256 (default of comparable knobs)

# Knob #11: ADAPTIVE_GROWTH_THRESHOLD (growth rate that signals saturation)
#   - Default: 5 (shrink when growth < 5%)
#   - Range: 0-10 (lower = eager shrinking, higher = cautious)

#   - Range: 13107-43691 (0.2 to 0.67 in Q48.16)
#   - Usage: make INITIAL_DECAY_SLOPE_Q48=13107 (0.2) or 32768 (0.5) or 43691 (0.67)
#   - DoE: OPP #3 tests 0.2, 0.33, 0.5, 0.67 to find optimal starting point for convergence

#   - Default: 500 (nanoseconds)
#   - Range: 500-5000 (balance between decay sensitivity and overhead)
#   - Usage: make DECAY_MIN_INTERVAL=1000 (slower decay) or 2000 (slower still)
#   - NOTE: as of the tick-based Loop #3 decay conversion (rev t, see
#     docs/working/architecture/VM-FLEET-ATTRACTOR-DESIGN-20260705.md),
#     Loop #3 no longer consults this value at all -- decay is gated on

#     doe_metrics.c still reports it as a metrics field; informational,
#     not load-bearing.

#   - Default: 1000 (ticks between inference runs)
#   - Set VERY HIGH (999999) to effectively disable inference (static mode)
#   - Set LOW for frequent inference (adaptive mode)
#   - DoE: OPP #3 tests 999999 (static, no Loop #6) vs 1000 (adaptive, with Loop #6)
#   - Measures: Inference engine cost vs benefit in optimized performance
$(eval $(call kconfig_int,HEARTBEAT_INFERENCE_FREQUENCY,1000))

# Knob #12: DECAY_RATE_PER_US_Q16 (Heat decay rate in Q16 fixed-point)
#   - Default: 1 (1/65536 heat units decayed per microsecond)
#   - Range: 0-65536 (0 = no decay, 65536 = 1 heat/µs)
#   - Half-life: ~6.5 seconds at default (100-heat word → 50-heat in 6.5s)
