Diagnosed from the live server (two users, two accounts, one shared log).
- history sync was gated off entirely on Baileys 6.7.x: the library derives
shouldSyncHistoryMessage from syncFullHistory when unset, and the connector
shipped syncFullHistory: false. Now both are passed explicitly, so behaviour
no longer depends on the resolved Baileys version. browser -> ['Mac OS', ...]
because PLATFORM_MAP only grants a desktop-grade sync to Mac OS / Windows.
- reconnects leaked their socket, leaving two writers over auth/: no end(), no
removeAllListeners(). ~15 reconnects/day produced 1422 Bad MAC lines, all on
the account's own LID device 0. Added teardownSock(), per-socket generation
guards, and a single-slot reconnect timer with exponential backoff.
- undecryptable messages (stubType CIPHERTEXT) were stored with empty text and
rendered as blank transcript lines; now labelled and counted. Text-less
protocol frames are dropped.
- fetchLatestBaileysVersion() ran on every reconnect; now cached for 6h.
- libsignal's direct console.error spam collapsed into one counted line, log
lines tagged with the linked account, console.log redirected off stdout.
Baileys pinned ^6.7.9 -> 7.0.0-rc14 (the range resolved to 6.7.24 for one user
and 6.17.16 for the other). RC is ESM-only, so index.js is now ESM.
Verified on skald-runtime:v4 (Node 20.19.2): initialize, tools/list, status,
list_chats, version fetch, QR, and logout -> teardown -> single reconnect.
Remaining gap: the store is still in-memory only, so synced history is lost on
the next process restart.
