v0.28.7 (2026-04-23)

Full Changelog Previous Releases

• Fix sync reliability: 1-fragment chunks + diagnostics bundle (v0.28.7)
  Ships two changes together as a paired fix + measurement:
  Chunk size (Part A): MAX_RECORDS_PER_CHUNK 10→4, CHUNK_BYTE_BUDGET
  2500→900. v0.28.6 aimed for 2 AceComm wire fragments per chunk but
  real cross-realm compression ratio is 23–26% (not ~18% as assumed),
  so chunks landed at 659–737 bytes = 3 fragments and the sync aborted
  at chunk 38/331 with p_frag_est=44.9%. The new budget produces
  compressed chunks ≤240 bytes = 1 fragment reliably. Per-attempt loss
  drops from ~45% to ~18%, 6-retry abort rate from ~0.8% to ~0.003%
  per chunk. Sync time ~18 min for a ~3300-record bootstrap; much
  shorter on subsequent syncs after bucket-delta convergence.
  Diagnostics (Part B): retry causes are now tagged (ackTimeout/nack
  for wire loss; combatAbort/zoneAbort/busyAbort/sendFailed for
  environmental aborts) so a noisy test session is distinguishable
  from a reliability problem. FinishSending output split into three
  per-peer audit lines: Sync outcomes (histogram + split aborts),
  Retry causes (chunkFail vs correctly back-solved p_frag using
  observed avg fragments per chunk), Compression (min/med/max
  percentage). Per-chunk bytes and ratio captured into chunkOutcomes.
  The v0.28.6 compression miss would now be visible from one audit
  line rather than requiring hand-parsing many chunk lines.
