Simulation now completes the full exchange with a genuine Paxton reader in password mode, and crypto mode read/write passes Proxmark-to-Proxmark. Firmware: - SOF was one bit period short. The lead-in that compensated for the lost head half bit was removed and nothing replaced it, so readers rejected every answer with a second START_AUTH. Default is now 6. - The edge-detect threshold was latched before being measured, so the value chosen depended on whether the Proxmark was in a field when sim started. It is now measured on field entry and re-armed when the reader leaves. - The percentile walk latched on run-scoped variables, so one attempt made outside a field poisoned every later one. - Field loss was detected from TIMESTAMP, which is free-running MCU time and never stalls. Detect it from receive silence instead. - Frames of a length the protocol does not have no longer reach the state machine; our own modulation tail was resetting the session and breaking every write. - A dropped edge merges two or three reader bit periods into one gap. Those bits were discarded; they are now recovered by decomposition, which is what made crypto mode work (AUTH decode 15% -> 100%). - Threshold selection is limited to 20 and 32 and settles in under 25 ms. Client: - lf hitag info printed a hardcoded 0x06 and reported 'Password mode' for every tag. It now reads page 3, takes -k (4 bytes password, 6 bytes crypto), and says so when the config cannot be read. - lf hitag restore: writes a dump back in dependency order - user pages, then key material, then config last - validates the config byte, and prints the credential the tag will require afterwards. - lf hitag crack2 now reports why it failed instead of a bare 'fail'. - trace list: bit count moved to its own column, relative mode shows a Frame Delay Time row rather than renaming Start/End, --frame and -r rejected together.
