				+1. The app sends the user's browser to the SPA page ``/connect/authorize``.

				+   the app's registered callback URL with that code.
			
 
				+2. The app's server calls ``POST /connect/token`` with the code, its client
			
 
				+   secret and the PKCE verifier, and receives the user's identity and
			
 
				+   permissions.
			
 
				+
			
 
				+What the app never gets is the user's Bambuddy login token. What a code is
			
 
				+worth is deliberately small: single use, 60 seconds, bound to one app, its
			
 
				+exact callback URL and the PKCE challenge, and only redeemable with the app's
			
 
				+secret.

				+Sign-in through an app only exists while Bambuddy authentication is enabled.
			
 
				+With it disabled there are no users to sign in, and both authorize and token
			
 
				+answer ``auth_disabled`` so the app can fall back to its own login rather
			
 
				+than let everyone in.

				+the update check already talks to. No Bambuddy server is contacted and nothing
			
 
				+about this install is sent: whether a message applies here (version range,

				+The file is written by the maintainers' registrar and signed with Ed25519:

				+    {"format": 1, "key_id": "...", "signature": "<base64>", "payload": {...}}

				+the middle can make Bambuddy show a message. The payload's ``serial`` only goes
			
 
				+up; a feed older than one already accepted is refused, so an old signed file
			
 
				+cannot be re-served to bring back a withdrawn message.
			
 
				+
			
 
				+The feed is the full current list. On every accepted fetch the stored set is

				+
			
 
				+    Material and colour alone cannot answer this: PLA Basic Black and PLA Matte
			
 
				+    Charcoal are both PLA at ``#000000``, which is why a Matte roll was linked to
			
 
				+    the Basic filament (#2907). The name is the only field on a Spoolman filament
			
 
				+    that carries the line.
			
 
				+
			
 
				+    Three spellings count, ranked by how much of the line they carry:
			
 
				+
			
 
				+    0. the sub-brand itself ("PLA Matte") -- what Bambuddy names the filaments
			
 
				+       it creates, and has since before this fix;
			
 
				+    1. the line folded into the colour ("Matte Charcoal", "Tough+ Black",
			
 
				+       "Brown Galaxy") -- how SpoolmanDB names every Bambu Lab entry outside PLA
			
 
				+       Basic, and so what a filament taken from the library used to be called;
			
 
				+    2. the bare colour name ("Black") -- how SpoolmanDB names PLA Basic, and the
			
 
				+       lines that have a base material of their own (ABS, ASA, PLA-CF ...).
			
 
				+
			
 
				+    Rank 2 is the weak one and callers must prefer anything better. "Black" is
			
 
				+    the bare name for PLA Basic, PLA Tough, PETG HF and TPU 90A alike, so on its
			
 
				+    own it cannot tell two lines of the same material apart -- it is accepted
			
 
				+    because an existing instance is full of filaments called that and refusing
			
 
				+    it would duplicate every one of them.

				+(core spec, no Bambu/Orca ``Metadata/`` entries) is enough: both CLIs load it

				+Copies are pre-placed on a simple shelf grid with a gap between footprints.

				+"""OIDC group sync (#3107).
			
 
				+
			
 
				+Mirrors the LDAP group sync semantics from api/routes/auth.py
			
 
				+(`_sync_ldap_user`) for OIDC logins: the provider's ``group_mapping``
			
 
				+configures which Bambuddy groups the IdP is allowed to manage, and every
			
 
				+login replaces only that managed slice — manual assignments to any other
			
 
				+group survive (#1292, same fix the LDAP path needed).
			
 
				+
			
 
				+Differences from LDAP worth stating:
			
 
				+
			
 
				+- LDAP reads group DNs from the directory entry. OIDC reads group values
			
 
				+  from a JWT claim, and providers disagree on the shape: Keycloak ships a
			
 
				+  JSON array, Authentik ships an array, Logto and some legacy setups ship a
			
 
				+  space- or comma-separated string. ``extract_idp_groups`` accepts both.
			
 
				+- LDAP has a ``default_group`` fallback when no mapped group matches. The
			
 
				+  OIDC path already has ``default_group_id`` applied at account creation,
			
 
				+  and re-asserting it on every login would fight manual upgrades: an admin
			
 
				+  who promotes an auto-created user out of Viewers would see the promotion
			
 
				+  reverted at the next SSO login. So the OIDC sync has no fallback — an
			
 
				+  empty resolved set simply means "the IdP grants none of the mapped
			
 
				+  groups", which removes exactly the mapped groups and nothing else.
