v0.28.6 (2026-04-22)

Full Changelog Previous Releases

• Fix sync reliability: shrink chunks to 2 fragments (v0.28.6)
  v0.28.5 logs showed the 1.0s gap floor worked as designed (no more bursts)
  but chunks still aborted at a high rate — chunk 1 of fresh syncs needed
  3–5 retries, and chunk 4 of the best run failed all 6 retries plus NACK
  retransmits. Observed per-attempt chunk loss was ~67%, implying ~24% per
  wire-fragment drop on cross-realm whispers.
  The v0.28.5 chunk revert to 25/3200 did not actually reduce fragment count:
  compressed chunks stayed at ~836 bytes (still 4 fragments, ceil(836/255)).
  The 3-fragment threshold is 765 bytes; we never crossed it.
  • Shrink chunks further: MAX_RECORDS_PER_CHUNK 25→10, CHUNK_BYTE_BUDGET
    3200→2500. Target compressed size ~450–510 bytes, i.e. 2 wire fragments
    per chunk. At 24% per-fragment drop this gives ~42% per-attempt chunk
    loss and <1% 6-retry failure per chunk.
  • Pin the conservative 1-fragment fallback (5 records / 1500 byte budget)
    as a commented block next to the live constants in Sync.lua, with a
    "when to flip" section in CLAUDE.md's Sync subsystem notes. Flip if
    v0.28.6 still aborts or p_frag_est stays above ~15%.
    Update the chunk-size assertion in spec/sync_spec.lua to 10.
