* Fix fragmentation + BLE long-write + padding - Accumulate CBATTRequest long writes by offset and decode once per central - Decode original packet after fragment reassembly (preserve flags/compression) - Switch MessagePadding to strict PKCS#7 and validate before unpadding - Make BinaryProtocol.decode robust: try raw first, then unpad fallback - Unpad frames before BLE notify; fragment when exceeding centrals' max update length - Skip notify path when max update length < 21 bytes (protocol minimum) Verified large PMs and announces route without decode errors and peers show reliably. * Tests: fix weak delegate lifetime, legacy constants, and unused vars; fragment unpadded frames - BLEServiceTests: hold strong reference to MockBitchatDelegate - IntegrationTests: fix inline comment braces; replace removed types with test-safe values; use numeric 0x06 for legacy handshake resp checks - BinaryProtocolTests: remove unused minResult variable - BLEService: fragment the unpadded frame so fragments are efficient * tests: add Noise rehandshake recovery test; document in-memory test bus and autoFlood; stabilize large-network broadcast * tests: align suite with current behavior (compression, padding, routing, nonce); deflake and stabilize --------- Co-authored-by: jack <jackjackbits@users.noreply.github.com>
