Expand description

Enhanced tier policy with EMA + popcount + recency scoring.

Score = w_ema * ema_rate + w_pop * (popcount(window)/64) + w_rec * exp(-dt/tau)

Fields§

§alpha: f32

EMA smoothing factor (0..1). Higher = more responsive to recent access.

§tau: f32

Recency decay time constant. Larger = slower decay.

§w_ema: f32

Weight for EMA access rate in score.

§w_pop: f32

Weight for popcount (recent tick activity) in score.

§w_rec: f32

Weight for recency (time since last access) in score.

§t1: f32

Score threshold for Tier1 (hot).

§t2: f32

Score threshold for Tier2 (warm).

§t3: f32

Score threshold for Tier3 (cold).

§hysteresis: f32

Hysteresis margin. Upgrade needs score > threshold + hysteresis, downgrade needs score < threshold - hysteresis.

§min_residency: u32

Minimum ticks a block must stay in its current tier.

§max_delta_chain: u8

Maximum delta chain length before compaction.

§block_bytes: usize

Block size in bytes.

§tier1_byte_cap: Option<usize>

Maximum bytes allowed in Tier1.

§warm_aggressive_threshold: Option<usize>

Use 5-bit instead of 7-bit when warm set exceeds this byte count.
