Stop three ways the collector and the forms wrote things nobody asked for
A review of last week's device-identity work found these; two were writing bad data and one was reproduced against a live server before being fixed. AN UPDATE COULD BLANK AN ASSET NUMBER, on all six asset update paths. Create validates it and the column is NOT NULL, but the conflict check only runs when the value DIFFERS, and '' collides with nothing - so an empty assetnumber went straight through to a required column. This is the likely source of the assets found with no number: a form that loaded blank and was then saved. MACHINEFORM COULD LOAD BLANK AND LET YOU SAVE IT. One try/catch wrapped eight reference loads AND the machine fetch, so a single transient failure among them - one page of listAll() timing out during a collector cycle is enough - rejected the whole block and rendered a fully editable EDIT form with every field empty, the error banner far below next to Save. Typing an asset number and saving then wrote the blanks over a real machine. The record now loads in its own try, and a failure shows the reason INSTEAD of the form: an empty edit form is indistinguishable from a record whose fields are genuinely empty. NAMING A DEVICE THAT DID NOT RESOLVE STILL MINTED A TWIN. Both device paths warned "not linked" and then fell through to mint <HOST>-PARTMARKER or <HOST>-CMM - the hostname-derived twin the resolution order exists to prevent. The warning was true about the typo'd number and false about the twin. Naming a device is a commitment: if the name does not resolve, or resolves to the wrong kind of thing, link nothing and say so. Silence still means "work it out", so a bay with no file keeps the reuse-then-mint behaviour it always had. TWO PCS COULD BOTH HOLD ONE DEVICE, ACTIVELY, WITH NO WARNING. Verified against a live server: report as one host, then as another naming the same marker, and both controls rows stayed active. Neither device path had ever looked at who else held the target - only at links whose source was THIS PC - so a replaced PC kept its link forever and an asset-id.txt copied to a second bay claimed the device silently. It now reuses the machine link's rule rather than inventing a second one: an incumbent that has gone quiet past the claim window or been moved off In Use has yielded and is archived, never deleted; a live incumbent keeps the device and the challenger is recorded dormant. The swap test asserted the old behaviour and now asserts the new one, split in two: a live incumbent keeps it, and handover completes once the incumbent yields. Two other tests were passing while their names lied - the unknown-device one checked only that the typo'd asset was not created, not that nothing was linked, and it passed while a twin was minted beside it. |

One enrollment file names the device, for every bay without a registry
A bay with an NTLARS/eDNC MachineNo registry is identified by it, and a CMM by cmmid.txt. Everything else - Keyence, Genspect, wax-trace, part markers, and whatever a site declares next - had no stable identity at all, and the two mechanisms that stood in for one both key off the PC: reuse looks for a prior link from THIS PC asset, and minting builds `<PC number>-<SUFFIX>` where a PC's number is its hostname. Both survive a re-image. NEITHER survives a PC SWAP. A new hostname is a new PC asset with no prior link and a predicted number that has never existed, so the same physical device gets a second record while the first keeps its config and its backup history under a dead PC's name. That is how 43 legacy MT-#### tools ended up shadowed by minted twins, three records deep in places. The metrology path learned this and gained an explicit id file; the part-marker path was modelled on the metrology path as it stood BEFORE that fix, so it inherited the defect - and its own docstring said so, describing minting "the same way it already mints a CMM". C:\Enrollment\asset-id.txt is now that identity for both, and for anything declared later through subordinatedevice_<pctype>. It holds one line, the device's assetnumber, and deliberately does NOT record what kind of device it is: the pc-type already does, so a new device type needs no new file and no client change. Resolution puts it first, ahead of everything PC-derived. NOT machine-number.txt. machinenumber answers "which bay is this" and is what GE-Enforce TargetMachineNumbers gates on, so naming a device there would silently stop every bay-gated manifest entry from matching. A part marker still files partof the operation from machinenumber; asset-id.txt changes which marker the PC controls, not which operation that marker belongs to. The wire field is `deviceid` rather than `assetid`, because assetid is already this contract's RESPONSE field for a PC's integer primary key - the two would have sat side by side meaning different things. measuringtoolid, shipped in 0.12.0, is accepted as an alias and the client still reads the older file, so a bay staged in the last day keeps reporting; deviceid wins when both arrive. Two guards, shared by both device families: a value that resolves to nothing warns instead of minting a phantom, and a value that resolves to the WRONG KIND of asset is refused with the asset named, so a machine number pasted into the file cannot be filed under a device label the collector also owns. Row creation is now one helper instead of a copy per path, because the named and minted branches both need get-or-create on the extension row and the control link. 1744 tests green, including a new file that pins the swap case both ways - with the file one device, without it two. Five of its tests failed first time because the fixtures built bare assets with no extension row and the type guard refused them, which is the guard working. VERIFIED ON WINDOWS 11 (build 26200), five cases: the new file alone; both files present, new winning; the legacy file alone; neither, sending no field; and a padded value with a trailing line. |
