GitHub Actions needs.<job_id>.result skipped required check success job conclusion official documentation
💡 Result:
In GitHub Actions, a job that is skipped due to a conditional (if statement) reports its status as "success" [1][2][3]. Consequently, such a job will not prevent a pull request from merging, even if it is configured as a required check [1][4][3]. For needs.<job_id>.result checks, the following points are authoritative: 1. Result Values: The needs.<job_id>.result property can take the value "skipped" when a dependent job is skipped [5]. 2. Success Interpretation: While a "skipped" job reports its status as "success" to the overall workflow and PR check system [1][4][3], the specific needs.<job_id>.result context value will explicitly be "skipped" [5]. 3. Dependency Behavior: By default, if a job in a needs list is skipped (or fails), any dependent jobs are also skipped [6][7]. To ensure a dependent job runs regardless of the dependency's outcome—or to specifically handle "skipped" results—you must use the always() conditional function [6][7]. Example of handling "skipped" jobs in a dependency: If you need a job to proceed even if a prerequisite job was skipped, you can structure your if condition to check for both 'success' and 'skipped' results [8]: if: ${{ always && (needs.job_id.result == 'success' || needs.job_id.result == 'skipped') }} This approach allows you to explicitly manage logic when a prerequisite job has been skipped rather than having the entire dependency chain implicitly skipped [6][3].

明确 result 与 conclusion 的来源。
若 aggregator 读取 needs.<job_id>.result，该字段仅返回 success、failure、cancelled 和 skipped。timed_out、startup_failure 与 neutral 属于 Check Run/Check Suite 的 conclusion 模型。请明确读取字段、取值表和失败判定，避免混用两种状态模型。

GitHub Docs troubleshooting required status checks workflow skipped path filters Pending required check job skipped
💡 Result:
When a GitHub Actions workflow is set as a required status check in your branch protection rules, it must report a success status to allow a pull request to be merged [1][2]. If that workflow is skipped because of path filters (using paths or paths-ignore at the workflow level) or branch filters, the workflow does not execute, and therefore never reports a status [1][3][4]. Consequently, the check remains in a "Pending" (or "Expected — Waiting for status") state, which blocks the pull request from being merged [1][3][5]. GitHub explicitly advises against using path or branch filtering to skip workflows that are required [2]. Because there is no branch protection setting to treat a missing (skipped) check as "passed," you must use alternative strategies to satisfy the requirement [3][4]. Recommended workarounds include: 1. Gate with Job-Level Conditionals: Instead of filtering at the workflow level, trigger the workflow on all events but use job-level if conditions to determine whether to execute the specific tasks [4][5]. A job skipped by an if condition reports a status of "Success" to GitHub, which satisfies the required status check [3][4]. You can use tools like dorny/paths-filter in an early, lightweight "pre-job" to compute the filter logic and output the result to subsequent jobs [4][5]. 2. Use a Passthrough (Dummy) Job: If you must keep the workflow-level path filters, create a secondary "fallback" or "passthrough" workflow that triggers when the main workflow is skipped [3][5]. This workflow should have the same name as the required check and simply exit successfully (e.g., echo "Skipped; passing") [3][6]. This ensures that when the main workflow is skipped, the required check name is still reported as a success [3][6]. Note that option 1 is generally preferred as it is cleaner and avoids creating multiple workflow files, though it may consume a small amount of runner time for the initial evaluation job [4][5].

修正 workflow 级 paths: 的行为描述。
因路径过滤而跳过的 workflow 不会产生成功状态，关联的 required check 会保持 Pending，并阻止合并。请将“零 required check”及“ruleset 静默匹配不到”改为该行为，并区分 workflow 级过滤与 job 级 if: 跳过。

GitHub Actions official documentation needs context result skipped job required status check workflow paths filter pending
💡 Result:
In GitHub Actions, the behavior of a required status check depends on whether the entire workflow is skipped or only a specific job is skipped [1][2]. 1. Workflow-level skipping (e.g., via 'paths', 'branches', or commit message triggers): If a workflow is skipped because of a trigger-level filter, the check associated with that workflow never executes [3][4][5]. Consequently, the status check remains in a "Pending" (or "Expected") state indefinitely [1][3]. Because the required check never reports a success conclusion, any pull request requiring it will be blocked from merging [1][6][7]. 2. Job-level skipping (e.g., via an 'if' condition): If a specific job within a workflow is skipped due to a conditional, it reports its conclusion as "skipped" [8][7]. By default, GitHub branch protection treats a skipped job's status as "success," which allows the required status check to pass and the pull request to be merged [9][10][2]. Recommended Solutions: - Avoid requiring workflows that can be skipped via trigger-level path or branch filters [1][5]. - If you must use path filtering for a required check, use a workflow that always runs but performs filtering internally (e.g., using 'dorny/paths-filter' in an early job) [7][5]. This ensures the workflow always reports a status [7]. - Alternatively, use a "gate" or "passthrough" job that depends on your conditional job [8][4]. By using 'if: always' on this gate job, you can evaluate the result of the conditional job and force a "success" or "failure" result even if the previous steps were skipped, ensuring the required check is always satisfied [8][7].

success|skipped 才算过收紧为仅 success 算过；业务仓事件互补 job（deps/deps-audit 等）的结构性预期跳过改为 aggregator 内显式 EXPECTED_SKIP 白名单；required 链路 workflow 禁用 workflow 级 paths 过滤（唯一豁免：AI_Web_School contract-watch，非 required）。配套实现 PR：.github 仓（gate.yml + standards）、CI-Workflows ci.yml、各业务仓 ci.yml（随后逐一提）。
