the language
skip
Swallow the error and let the DAG continue · the task produces no output, and the original error stays readable at `tasks.<id>.error`. Exactly one of `recover` · `skip` · `fail_workflow`. One of 62 words the served contract declares, projected from workflow.schema.json, the same file your editor validates against.

the contract
1 declarationthe failure grammar · this word only ever speaks inside the recovery block, so meeting it means you are reading what happens when something breaks
Descriptions are the schema's own; the deeper invariants (value languages and regexes) ride the same projection. A miss is a nika check finding before anything runs.
