- _get_level_hashes: use separate SQL without prefix64<=? for level 0.
UINT64_MAX cast to sqlite3_int64 becomes -1, making prefix64<=-1 always
false for positive prefixes → bitmap always 0 → sync never exchanges data.
- member_sync_init: add _rebuild_all_trees to scan all peers_* tables and
call merkle_sync_recompute_path for each member. Ensures merkle_tree_hash
has entries for members added before merkle sync existed.
- Add 2-byte dlen prefix to terminal BATCH/HASHES data so receiver knows
exact byte count — fixes rem=0 bug that truncated multi-item BATCHes.
- Fix synthetic HASHES prefix_bytes: use merkle_sync_prefix_bytes(next_lvl)
for both declaration and _prefix_write, not current level's pb_i.
- Fix initiator never getting _session_done: responder sends confirmation
HASHES(is_data=1,level=0) before _session_done so initiator's done_cb fires.
- Add level==0 guard in _member_get_items/_member_update_bucket_hash
to prevent SQL queries with bogus mask on virtual root level.
_prefix_write was writing the least significant pb bytes of the 64-bit
prefix, but the protocol expects the most significant pb bytes (bits
63..64-pb*8). For pb<=4 these ranges are disjoint → wire always got
zeros. _prefix_read also lacked the final left-shift to align the
result at bit 63.
This caused all level>=2 merkle sync requests/batches to receive
prefix=0 instead of the real prefix, making get_items/update_bucket_hash
find zero members → handle_batch len=7 with no data → sync completed
without actually exchanging member data.
- Remove is_dm column from channels table (dm detection by member count)
- Rename member name column to userinfo — extensible json_flat format
- Add json_flat.c/h library for compact JSON serialization
- Fix join_sig message format: use ch_x25519+ch_ed25519 instead of channel_id string
- Remove name from join_msg body (now in userinfo via json_flat)
- Update chat_core, chat_sync, member_sync, db_manager to new format
- Add topo_strategy.txt — архитектурные заметки по топологии
- chat_core_sync_my_addresses: DELETE + INSERT с подсчётом строк, CHECK verify
- chat_core_connect_from_invite: DELETE + INSERT с IP:port
- member_sync_put: DELETE + INSERT с IP:port, warn если addrs_data=NULL
- cs_handle_channel_info_resp: адрес инвайтера из ETCP link
- cs_handle_channel_join: адреса джойнера
- cs_handle_peer_upsert: адреса пира
- cs_handle_welcome: адреса из WELCOME
