Decode Event 0x210 subtype 349 into typed online-device snapshots, including QQ-compatible low-byte client type normalization and one-entry-per-device-category projection.
Keep replacement snapshots outside system-message deduplication, reject malformed device identities observably, and add wire-level regressions for complete, packed, repeated, and invalid payloads. Live verification covered mobile account switching without requiring native changes.
