Assign printers to a machine, and let the PC that drives it inherit them
Printers belong to the bay, not to the box currently driving it. The assignment
goes on the MACHINE asset and reaches whichever PC controls it, so a reimaged or
swapped PC comes back with the right printers and nothing had to be saved off the
old one. The asset register is the backup.
New relationship type usesprinter ("this printer is installed here"), beside the
existing defaultprinter ("which of them is the default"), both seeded and both
given a propagation rail through controls. The rails are consumed at READ time
only: the create-time fan-out skips directional through-types, and controls is
directional, so assigning a printer to a machine does not copy rows onto its PC.
That is what keeps own-beats-inherited possible.
Resolution for a PC is its OWN rows if it has any, otherwise one hop out along
controls to the machines it drives. Whole set at a time, not merged: a PC with
its own assignment is overriding the bay deliberately, and the UI has to say so
or a tech "fixing" a bay by editing the PC will shadow the machine's record and
wonder why they keep disagreeing.
GET /api/printers/for-host/<hostname> is what the convergence client asks every
cycle. Resolved by hostname because the collector upserts PCs by hostname and an
office PC has no machine number. An unknown host, a site without the computers
plugin, and nothing assigned all return an empty set - that is the client's
designed no-op and it must stay indistinguishable from "assigned nothing".
PUT /api/printers/assignments/for-asset/<id> reconciles the whole set in one
call. The endpoint was specified, documented and asserted by three tests, and
never written - the verification pass caught that, with four failures. It
validates the default BEFORE any write, so a rejected request changes nothing;
soft-deletes rows that went away; and REACTIVATES soft-deleted rows rather than
inserting, because the unique constraint spans inactive rows and a blind insert
after an unassign raises IntegrityError on MySQL while passing on SQLite.
One default per asset, enforced here because the schema cannot: the constraint is
(source, target, type), which accepts two different defaults quite happily. Two
active defaults are still reachable through the generic relationships endpoint,
where the oldest silently wins - recorded in the proposal as the next thing to
close.
printerdrivers gains drivername: the exact string the INF declares, which
Add-PrinterDriver matches on and nothing else. Deriving it by parsing INFs on
hundreds of bays is fragile; a human confirming it once is not.

Generate the collector script per site, and bring EventSaver into the repo
A site adopting ShopDB had to be handed two files and told what to edit in them. Both are now the product's, and one of them the server writes for you. GET /api/computers/client-script (admin) returns Report-AssetToShopDB.ps1 with this site's values already in it: site_base_url becomes the -ApiUrl default and the new computers_routableranges setting becomes -AllowedRanges. Only the PARAMETER DEFAULTS are substituted - the copy in plugins/computers/client/ stays runnable, so there is no second version to drift from the first - and everything stamped stays overridable by argument or registry, because a bay may need to differ from its site. Settings > Computers > Asset reporter edits the ranges, downloads the script and shows its SHA-256. The collector key is deliberately not stamped in, and a test fails if it ever is. That file lands on every shop-floor PC, and a token spread across hundreds of bays cannot be rotated quietly; it stays in the registry, provisioned per ADOPTING-AT-ANOTHER-SITE.md. The routable ranges are the last thing that was hardcoded in that script. They are now a setting, so West Jefferson's two CIDRs move out of source code and into that site's own configuration - which is what ADR-015 asks for - and a site that sets nothing still works, because the script falls back to the NIC carrying the default route. EventSaver joins it in plugins/slides/client/, source only: EventSaver.cs and EventSaver.ini, no compiled .scr - a binary is a release asset, like the installer exe. The share path that was compiled into Config.Folder is gone. It used to be the fallback when the ini was missing, which silently pointed a new site at the reference site's file server; it is now empty, and failing visibly beats displaying another site's slides. Verified by compiling the edited source in the Windows VM with the in-box csc.exe: 15,872 bytes, exit 0. Also: the DSC example in the adoption guide gains a CollectorRanges resource and stops passing -ApiUrl to a script that already reads BaseUrl from the registry the same example writes, and the guide points at the generated download instead of hand-editing a URL. The contract test caught the endpoint importing shopdb directly for the version string, which ADR-002 forbids a plugin from doing. The product and contract versions are in app.config now, which a plugin reads through current_app. Adds docs/proposals/printer-assignment.md: assign printers to a PC in ShopDB and let the bay install them, with what the fleet data says about drivers - HP and Xerox cover 41 of 44 printers with universal drivers, there are no Brother printers at all despite 208 files of Brother inkjet drivers in the installer, and printerdrivers holds one row pointing at a per-model folder instead of a universal driver. |
