Saving a K-profile was fire-and-forget. set_kprofiles_batch published and returned True, and the printer's extrusion_cali_set answer was logged at DEBUG and dropped, so a write the printer refused was reported to the user as saved (#2718, reporter @jmoore-skild). The reason it could not simply be gated on: the answer itself was wrong. Single-nozzle firmware returned result:"fail" with reason:"invalid tray_id" on writes that demonstrably applied. Measured against an X1C and an H2D over MQTT, the cause is the tray_id:-1 Bambuddy itself put in the payload. Sending three otherwise identical writes isolated it: tray_id:-1 fails, tray_id:0 succeeds, and cali_idx:-1 is accepted either way, so only that one field is at fault. The H2D ignores the value entirely; the X1C validates it, complains, and applies the write anyway. BambuStudio always sends a real tray_id and defaults it to 0 for a manually entered profile. With tray_id:0 the acknowledgement is honest, and the printer echoes back the sequence_id we sent -- confirmed for extrusion_cali_get, _set and _del on both printer classes -- so it can be matched to the write that caused it. Writes now return their sequence_id and the routes await the verdict, turning a real failure into an error that carries the printer's own reason. A printer that stays silent is still treated as success: no answer is not evidence of refusal, and firmware that never answers must not turn every save into an error. Raises the ack to INFO. It sat at DEBUG, so the one line that explains a failed save was absent from every support bundle -- the same reasoning that put ams_filament_drying at INFO for #1447. Also fixes extrusion_cali_set building its payload from str(self._sequence_id) without incrementing first, reusing the previous command's id. Harmless while nothing correlated on it, fatal now that the write path does. Adds supports_nozzle_flow_type() for the Standard / High Flow choice, which the K-Profiles UI previously showed as "Not reported by printer" -- not a value anyone can save. Most printers omit the nozzle identity from their calibration table entirely, and the slicer treats that as Standard rather than unknown; Bambuddy now does the same and keeps the choice editable. The field is hidden only where the model ships a single nozzle variant, using the slicer's own rule (len(nozzle_volume) // len(nozzle_diameter) > 1 over the machine preset) evaluated across every bundled Bambu profile. That puts only A1, A1 Mini and A2L on the hidden side -- it is not the single- versus-dual-nozzle split, since P1P, P1S, P2S, X1, X1C, X1E and H2S are all single-nozzle and all carry two variants. Editing a profile also no longer writes back an empty nozzle_id. Wiki records that on printers which omit the field the chosen flow type is discarded by the firmware and reads back as Standard, in Bambu Studio as well, so it does not get filed as a bug again.
