- Google-style docstrings with Args, Returns and Raises for resolve() and every registry and configuration helper, and docstrings for the settings classes; ruff now checks docstrings against the Google convention. - Remove vm_max_lifetime_s: removing VMs after a lifetime is the consumer's policy, not interCEde's. - Import Callable from collections.abc, like the rest of the code.
A verb says that the call builds something, and get_backend() no longer reads like the backend itself.
ARCConfig, HTCondorCEConfig, CloudConfig, BatchLocalConfig and BatchSSHConfig replace the flat BackendConfig, which is now their union, chosen by kind (and by transport for batch). A consumer can still pass a plain mapping, such as a TOML table. - Every field is declared once, on the model of its kind: the internal settings classes, the hand-kept field lists and resolve() are gone, so a configuration is validated once instead of twice. - validate_config() checks a configuration and returns its model; registry.get_backend() uses it. A model is checked again, so one changed with model_copy() cannot carry fields of another transport to a backend. - Errors never repeat a value they were given, since it may be a secret, and name the expected fields when a field does not belong to the kind. - The configuration tests use the public API only. The SSH auth mode is now one value (auth = "key") instead of a list.
griffe-pydantic renders every field of each configuration model, inherited ones included, with its type, default and description, so the reference cannot drift from the code like the hand-written table could.
The merge of stack/registry kept a helper and a section header from the old test_config.py; the helper referred to resolve() and BackendConfig.model_validate(), which no longer exist.
Brings in the per-kind configuration models of stack/registry, and moves the credential code onto them: - credential_requirements(config, scopes) in _backends/credentials.py replaces the methods on the removed internal settings classes, with the same rules: a CE asks for its endpoint with the configured token and/or proxy, SSH for user@host:port unless an SSH agent holds the key, and a local batch system for nothing. - registry.get_backend(config, credentials) checks the provider and passes it to the parts that authenticate: single-class backends and transports. - The credential requirement tests move from test_config.py to test_credentials.py and build their configurations through validate_config().
Two tests had moved without changing, which only made the diff harder to read.

…, squash-merged as DIRACGrid#29)
A value given by mistake, such as a misspelled field or plain data in a CredentialSet, may be the secret itself. Validation errors now hide their input, as the configuration models already do.
The message comes from the consumer's code and may hold a token or a secret URL. The AuthenticationError names only its type; the exception itself is still available as __cause__.
The fields were described in comments, which the generated reference does not show. They now use attribute docstrings, as the configuration models do.
Name every argument and the return value, and drop the blank lines before closing quotes.

…n, and removed auth value from config as it was not used
Moves test_fake_backend.py to tests/unit/backends/fake/, ready for the HTCondor tests that follow. The tests themselves do not change. Part of DIRACGrid#23.
Renders a submit description from a plan: one process per copy, per-copy values indexed by ProcId, quoting, and refusing what a description cannot hold. It sets no policy on the job except keeping finished jobs until they are purged, so output can be collected again. Shared with the HTCondor scheduler to come (DIRACGrid#21), so it knows nothing about any backend. Expected values were checked against HTCondor 25. Part of DIRACGrid#23.
Builds the tools' command lines and reads what they print: condor_submit -terse, condor_rm, and the job ads of condor_q and condor_history, mapped to the common JobStatus. A finished job's result comes from its exit, a removed job keeps the result it had, and any hold that interCEde did not cause counts as aborted. Part of DIRACGrid#23.
interCEde no longer supports proxies, so a description has nothing to say about one.

feat: the shared HTCondor core
Part of #23; #21 will reuse it. PR 1 of 6 for the HTCondor-CE backend.
No dependencies: this applies directly to
mainand can merge before or after #30.Adds
_backends/_htcondor, which holds what interCEde knows about HTCondor itself. Nothing calls it yet: the backend arrives in #35.What's added
submit: renders a submit description from a plan, with one process per copy and per-copy values indexed byProcId.commands: builds the tools' command lines, splits job ids into chunks of 100, and reads the output ofcondor_submit -terseandcondor_rm.status: reads job ads fromcondor_qandcondor_historyand maps them toJobStatus.test_fake_backend.pymoves totests/unit/backends/fake/, unchanged, so each backend has its own test folder.Decisions to check
leave_in_queue = (JobStatus == 4)), so output can be collected again. This is the only policy set on a job: no holds, retries or periodic removal.Aborted.LastJobStatusdecides, so a finished job that was purged staysDoneorFailed.ValueError.Testing
80 new unit tests, with no HTCondor needed. Expected values were checked against HTCondor 25 (
condor_submit -dry-runand a live schedd).
