Refuse a truncated project, and drive the whole path from the probe
`upload_project_file` already existed - as a `GenericPrinter` trait method, which is why a grep for `pub async fn` missed it and this commit nearly reimplemented it. It logged `written` and `byte_count` next to each other and never compared them, so a short write was something you could only notice by reading the logs afterwards, and the next line printed the truncated file anyway. A `.3mf` is a zip: cut the end off and the central directory goes with it, so the printer gets an archive it cannot open. That is also the failure a slow transfer invites, and this transfer is slow - 4.96 MB took 31.3s, so a 62 MB project is minutes of exposure. `print-project <local> [name]` runs that method against a real printer, so the harness tests the production entry point rather than the three pieces in sequence. It deliberately takes no `--ams`: the whole point is that the mapping comes out of the archive. Gated like `start`, on a terminal state and `--yes-start-a-real-print`. Confirmed end to end on the P1P (2026-10-15, with the owner's go-ahead), with the same project the 2026-10-11 run used: the derivation read one PETG/GFG99/ `#2850E0` filament out of `Metadata/slice_info.config` and produced `mapping=[3]`, padded to five trays; 297,227 bytes went up with an exact byte count; `IDLE -> PREPARE -> RUNNING`. The AMS on that machine has slot 2 in black and slot 3 in blue, same product and same `tray_info_idx`, so picking slot 3 is the colour tie-break doing real work rather than a one-candidate match. |

Confirm the light and the upload on a real P1P
Four things were shipped unverified because the printer was off when they
were written. Three are now confirmed first-hand (P1P, 2026-10-15), and one
is settled in the opposite direction from what was assumed.
**`set_light` had never once reached a printer**, and `completion::run`
blinks a finished print's chamber light with it. It works - but "accepted" is
not "it changed": `ledctrl` answers `result: "success"` as soon as the
command parses, exactly like the print-control verbs. So `lights_report` is
now modelled on `PrintReport`, which is the only read-back there is, and the
probe polls it rather than printing a reassuring message. Setting the light
on and off reads `[{"node":"chamber_light","mode":"on"}]` / `"off"` back,
about 3s later. The field was observed on v1 even though only the v2 schema
declares it.
**The blink itself works at the rate it ships at.** `completion::celebrate`
is now public so the probe runs the real function instead of a copy: twenty
`ledctrl` commands half a second apart, which a printer is entitled to
refuse. None were refused, it returned after 10.35s, and the light ended
`off` as specified - a blink that leaves the light on would look like a
printer still working.
**The firmware's own `flashing` mode is not the better option.** It is
accepted, and the reply echoes all four parameters back
(`led_on_time`, `led_off_time`, `loop_times`, `interval_time`), so the
printer does parse them. But `lights_report` never reports `flashing` - it
stayed on the previous mode for 12s of polling. A firmware blink is therefore
unobservable: nothing can confirm it happened or tell when it ended, while
the self-driven blink is built from a call that reads back. That is a better
reason to keep `celebrate` than the one in the comment it replaces, which was
that `loop_times` semantics were unconfirmed. Whether the light physically
blinks is still unwitnessed - nobody was watching the machine.
**Multi-MB FTPS upload works, and is slow.** A 4.96 MB project archive went
up with an exact byte count and came back byte-identical (sha256). But it
took 31.3s - about 0.2 MiB/s - so the 62 MB project already on that card
would take six and a half minutes. Anything that uploads a job needs a
timeout budgeted in minutes, not seconds. The claim in `download`'s comment
that these files are "a few hundred KB" is gone; the card disproves it.
Also adds `delete`, because the probe left a 5 MB file on a real SD card and
there was no way to remove it. One explicit path, no globbing: the convenient
version of this deletes something somebody printed from last week. Used to
clean up, and the card is back as it was.
New probe steps: `light on|off|flash`, `blink`, `upload <local> [name]`,
`delete <path>`. 51 tests still pass.

Make the filament source explicit, and print from the AMS
`start_uploaded_file` hardcoded `use_ams: false` / `ams_mapping: ""`, which silently overrode whatever the slicer had chosen. On a P1P with an AMS and a project sliced for it, that is not a missing feature - it points the print at the external spool. Confirmed on 2026-10-11: the print started, heated to 250C, reached 1%, then the printer paused itself with `print_error: 50364420` and `tray_now: 255`. Nothing in the command's reply said so; `result` was `success`, because the command had been accepted. So `FilamentSource` is now a required argument with no default, because there is no safe default - picking wrong draws the wrong filament or none. The `ExternalSpool` variant sends the empty *string* the schema's trailing `oneOf` demands, and `ams` takes slots per project filament index and pads to every tray the printer has, per the padding rule in `schemas/bambulab/v1/common/ams/ams_mapping.schema.json`. It refuses an empty mapping (padding `[]` would mean `use_ams: true` with nothing mapped), one longer than the printer has trays, and any negative that is not -1. Confirmed live with the real mapping: `ams_mapping: [3,-1,-1,-1,-1]`, `use_ams: true` took the printer to RUNNING, `tray_now` became 3 - the slot the project was sliced for - and it ran past 1% to 13% with `print_error: 0`, where the external-spool attempt had paused. Finding the mapping needed reading the project back off the card, so FTPS gains `download`/`download_file` and the probe a `fetch` step. The archive's `Metadata/slice_info.config` lists each plate's filaments with `tray_info_idx` and colour - here one PETG GFG99 at `#2850E0`, matching AMS slot 3's `2850E0FF` - and `Metadata/plate_1.gcode` is present, which also confirms the hardcoded `param`. `upload_project_file` is left on the external spool and is the one remaining place that can pick wrong, because it is vendor-generic and an AMS mapping is a Bambu concept. It is unreachable - there is no start-print command on the uplink - and the fix is for it to derive the mapping from the `.3mf` it already holds, which needs a zip reader and so a dependency decision. |

Record what a real sliced project did, and widen the start guard
A second live run, this time against a project the owner sliced in Bambu Studio rather than a file already on the card, and through `start_uploaded_file` itself rather than a hand-built body - so the root-vs-cache fix is confirmed end to end. `gcode_file` in the printer's own status came back as `cube-test-2026-10-11.gcode.3mf`, 150 layers, print_type `local`. It also found a defect the first run could not. The print heated to 250C, reached 1%, and then the printer paused itself: `print_error: 50364420` (`0x03008004`), `hms: []`, `tray_now: 255`. 255 is the external spool, which is exactly what the hardcoded `use_ams: false` selects - so that pair overrode the slicer's own filament choice and pointed an AMS-sliced project at an external spool. The first run looked fine only because it was stopped during PREPARE, before filament mattered. The doc comment said that pair was "accepted, and the print ran"; it now says what it actually does, because silently changing which filament a print uses is worse than not supporting AMS at all. The `start` guard demanded IDLE, which meant the harness refused every print following a cancelled one - a Bambu reports an operator cancellation as FAILED. IDLE, FINISH and FAILED are all terminal; PREPARE, RUNNING, PAUSE and SLICING mean the machine is committed, and anything unrecognised is still refused rather than assumed idle. `bambu_cache_list` now prints nozzle/bed temperatures and remaining time. State plus layer number cannot tell a print that is working from one that is stalled: a P1P sits at layer 0 for minutes during bed levelling and purge, and the only thing moving in that window is the heat. |

Confirm the print path on a real P1P, and stop discarding its answer
Print control (pause/resume/stop) and print start are now both confirmed
against the P1P on the LAN, and doing that turned up three real defects.
`start_uploaded_file` published fire-and-forget, so the printer's reply was
thrown away. Asking it to print a file it does not have returned `Ok(())`,
and watching `print.push_status` could not tell that apart from a successful
start, since both leave the machine IDLE for a while. The printer does in
fact answer - `{"command":"gcode_file","param":"...","reason":"error
string","result":"fail"}` - and it echoes the `sequence_id` we send, so
`request` correlates it. Both this and `control_print` now go out as
correlated requests and run the reply through `print_command_outcome`.
The upload and the print command disagreed about where files live. `upload`
cwd'd into `cache/` while the printable projects are in the card's root: the
root holds 43 `<name>.gcode.3mf` archives, `cache/` holds the printer's own
extracted `<project>_plate_N.gcode` working copies with `.gcode.bbl`
sidecars. Those extracted copies are not independently printable -
`gcode_file` with `param: "/cache/Cube_plate_1.gcode"` was rejected for a
file the FTPS listing shows is right there - while `project_file` with
`url: "ftp:///Cube.gcode.3mf"` started a print. So the destination is now a
parameter and both halves point at `SD_ROOT`.
What the hardware settled, recorded in the doc comments: the `ftp:///` url
spelling is right, `param: "Metadata/plate_1.gcode"` works for a
single-plate project, `use_ams: false` + `ams_mapping: ""` is accepted, and
a stop during PREPARE/RUNNING moves the printer to FAILED, which is how
Bambu reports an operator cancellation. What it did not settle: all three
control verbs answer `result: "success"` on an *idle* printer, so the reply
means "accepted", not "the state changed" - callers still have to read
`gcode_state` back.
`PrinterCommand::ControlPrint` makes this reachable from the cloud at all;
until now pause/resume/stop existed in the proxy with no way to send them.
Still no start-print variant, now for a different reason: the path around it
is missing, not the hardware proof.
Also: `list_dir` for any directory (how the layout above was found, without
sending a print command to guess), `request_raw` for probing an unconfirmed
command shape, and two examples - `bambu_cache_list` (read-only) and
`bambu_print_probe` (gated steps, `start` needing both IDLE and
--yes-start-a-real-print).
