🌐 Web query:
For Prow BranchRequirements, how are non-optional presubmits with always_run: falseandrun_if_changed classified when they produce no status?
💡 Result:
In Prow, non-optional presubmit jobs (where optional is false) that are configured with always_run: false and a run_if_changed (or skip_if_only_changed) filter are classified as jobs that run conditionally [1][2][3]. When these jobs do not run—because the changed files in a pull request do not match the specified run_if_changed pattern—Prow classifies their status context as "required, if present" [1][4]. This means that while the job's status is not required to be present for the pull request to merge, if the job is triggered (manually or otherwise) and produces a status, that status must be successful [1][4]. In the BranchRequirements function, which partitions status contexts for branch protection, these jobs are identified by the j.TriggersConditionally method [1]. Because they are not "always run" and have conditional triggers, they cannot be strictly required at all times, as their status may not exist on every pull request [1]. Consequently, they are placed in the bucket of contexts that are required only if they are present [1][4].

Do not block conditionally triggered presubmit jobs with no status.
classify_jobs ignores always_run and other conditional-trigger metadata. It adds not_reported for every missing non-optional context. build_pr_result then reports each such entry as a blocker. Prow treats conditionally triggered non-optional jobs as required only if present.
Use the trigger metadata when adding not_reported, and update SKILL.md to document the distinction.

GitHub REST API pull request response schema user login string nullable official documentation
💡 Result:
<search_synthesis>
In the GitHub REST API pull request response schema, the login string of the user object is not nullable [1][2][3]. While the user field itself within the pull request object is defined as nullable (allowing for scenarios where a user may be a "ghost" or deleted account) [1][2][4][5], the login property within the Simple User object is explicitly defined as a required string [1][2][3]. Technical note: While official documentation currently defines login as a non-nullable string, it is important to be aware of identified discrepancies in the broader API specification. There are open issues in the github/rest-api-description repository highlighting that certain sub-fields (such as head.user) can return null in practice, even when the schema definitions may suggest otherwise [4][5]. Developers should implement robust error handling to account for potential null values in the user object context, even though the login field is schema-typed as a non-nullable string [1][4].

Handle nullable pull-request users before author matching.
gh_api passes the GitHub pull-request response without normalization. GitHub allows the pull request user object to be null for ghost or deleted accounts. build_pr_result dereferences pr_meta["user"]["login"] before match_tide_queries, so such a PR raises TypeError and prevents result generation. Normalize the nullable user object once, pass its login to match_tide_queries, and reuse that value in the returned author field.
