EntryRecord

Struct EntryRecord 

Source
pub struct EntryRecord {
    pub word_offset: u32,
    pub code_offset: u32,
    pub log_prior: i16,
    pub match_type: u8,
    pub flags: u8,

    pub embedding_offset: u32,

Expand description

Per-entry record (16 bytes packed). word_offset and code_offset are u24 (3 bytes); they point into the string pool. log_prior is signed Q4 fixed-point (one log unit per 16 integer steps, per inputx_scoring::Q4). raw_freq is the original pre-quantization corpus frequency (added v1.4.7 sub-phase A4 step 1) — it lets cement-side cement rebuild a lossless tiebreaker when two entries land in the same Q4 log_prior bucket (e.g. 乎/护 for code hu, both quantize to Q4=170; raw_freq distinguishes them).

Layout: u24 word_offset + u24 code_offset + i16 log_prior + u8 match_type + u8 flags + u32 raw_freq + 2 bytes reserved = 16.

raw_freq=0 on disk is the v1.4.6-era backward-compatible default (those bytes were bigram_offset, never written non-zero and never read), so old .idf blobs decode as raw_freq=0 — the only fallout is loss of the tiebreaker for legacy snapshots.
