Ingest (registration and MapRequest updates) now calls
dnsname.SanitizeHostname directly and lets NodeStore auto-bump on
collision. Admin rename uses dnsname.ValidLabel + SetGivenName so
conflicts are surfaced to the caller instead of silently mutated.
Three duplicate invalidDNSRegex definitions, the old NormaliseHostname
and ValidateHostname helpers, EnsureHostname, InvalidString,
ApplyHostnameFromHostInfo, GivenNameHasBeenChanged, generateGivenName
and EnsureUniqueGivenName are removed along with their tests.
ValidateHostname's username half is retained as ValidateUsername for
users.go.
The SaaS-matching collision rule replaces the random "invalid-xxxxxx"
fallback and the 8-character hash suffix; the empty-input fallback is
the literal "node". TestUpdateHostnameFromClient now exercises the
rewrite end-to-end with awkward macOS/Windows names.

Generalise the registration pipeline to a more general auth pipeline
supporting both node registrations and SSH check auth requests.
Rename RegistrationID to AuthID, unexport AuthRequest fields, and
introduce AuthVerdict to unify the auth finish API.
Add the urlParam generic helper for extracting typed URL parameters
from chi routes, used by the new auth request handler.
Updates #1850
Fix issues found by the upgraded golangci-lint:
- wsl_v5: add required whitespace in CLI files
- staticcheck SA4006: replace new(var.Field) with &localVar
pattern since staticcheck does not recognize Go 1.26
new(value) as a use of the variable
- staticcheck SA5011: use t.Fatal instead of t.Error for
nil guard checks so execution stops
- unused: remove dead ptrTo helper function
This PR addresses some consistency issues that was introduced or discovered with the nodestore.
nodestore:
Now returns the node that is being put or updated when it is finished. This closes a race condition where when we read it back, we do not necessarily get the node with the given change and it ensures we get all the other updates from that batch write.
auth:
Authentication paths have been unified and simplified. It removes a lot of bad branches and ensures we only do the minimal work.
A comprehensive auth test set has been created so we do not have to run integration tests to validate auth and it has allowed us to generate test cases for all the branches we currently know of.
integration:
added a lot more tooling and checks to validate that nodes reach the expected state when they come up and down. Standardised between the different auth models. A lot of this is to support or detect issues in the changes to nodestore (races) and auth (inconsistencies after login and reaching correct state)
This PR was assisted, particularly tests, by claude code.
