ptwm_core::prelude::read_prelude

crates/ptwm-core/src/prelude.rs:154
pub fn read_prelude(reader: &mut R) -> Result<Vec<PreludeEntry>, PtwmCoreError>

Convenience wrapper for cursor-based readers (used in tests).

rsfn

ptwm_core::prelude::shared_state_matches

crates/ptwm-core/src/prelude.rs:167
pub fn shared_state_matches(a: &PreludeEntry, b: &PreludeEntry) -> bool

Verify two `PreludeEntry` shared states with the same `shared_state_id` carry identical bytes. A multi-shard reader merging preludes across shards calls this to fast-fail on silently divergent shared state.

pub fn write_prelude(entries: &[PreludeEntry], out: &mut Vec<u8>) -> Result<(), PtwmCoreError>

resolve

Compose a PolicyFile + trust state into a ResolvedPolicy.

quantize

Shared PMF quantization + validation primitives. Used by PerGroupCodebook (PGC, alphabet=16, total=256) and Order1ScaleAC (alphabet=256, total=4096); each codec passes its own total constant.
