SEP variables incorrectly overrides for multiple policy
<!--- Please read this! Before opening a new issue, make sure to search for keywords in the issues filtered by the "regression" or "type::bug" label: - https://gitlab.com/gitlab-org/gitlab/issues?label_name%5B%5D=regression - https://gitlab.com/gitlab-org/gitlab/issues?label_name%5B%5D=type::bug and verify the issue you're about to submit isn't a duplicate. ---> ### Summary The variables defined in SEP are overridden by the same variable defined in a different policy. ### Steps to reproduce 1. Create new project 2. Apply a scheduled SEP with `GITLAB_ADVANCED_SAST_ENABLED` = true 3. Apply a triggered SEP and set variable to false 4. Make a commit, and the triggered SEP job uses the value of the scheduled policy (true) rather than the one set by the policy making the job (false) ### Example Project - https://gitlab.com/gitlab-org/security-risk-management/security-policies/team-member-environment/sashis-test-group/test-sep-advanced-sast/project-a #### [Pipeline with scheduled SEP](https://gitlab.com/gitlab-org/security-risk-management/security-policies/team-member-environment/sashis-test-group/test-sep-advanced-sast/project-a/-/pipelines/1980923350) ![Screenshot_2025-08-18_at_12.19.52_PM](/uploads/bd6e7d6f117d3ab96b5eb04af0b02b68/Screenshot_2025-08-18_at_12.19.52_PM.png) #### [Pipeline without scheduled SEP](https://gitlab.com/gitlab-org/security-risk-management/security-policies/team-member-environment/sashis-test-group/test-sep-advanced-sast/project-a/-/pipelines/1981000287) ![Screenshot_2025-08-18_at_12.19.56_PM](/uploads/58bd6bb0c5370cdffcc008ccfe1288d0/Screenshot_2025-08-18_at_12.19.56_PM.png) <!-- If possible, please create an example project here on GitLab.com that exhibits the problematic behavior, and link to it here in the bug report. If you are using an older version of GitLab, this will also determine whether the bug is fixed in a more recent version. --> ### What is the current *bug* behavior? - Variables defined in scheduled SEP are overridden in pipeline SEP ### What is the expected *correct* behavior? - Variables should not be overridden from a different policy ### Relevant logs and/or screenshots <!-- Paste any relevant logs - please use code blocks (```) to format console output, logs, and code as it's tough to read otherwise. --> ### Output of checks <!-- If you are reporting a bug on GitLab.com, uncomment below --> <!-- This bug happens on GitLab.com --> <!-- and uncomment below if you have /label privileges --> <!-- /label ~"reproduced on GitLab.com" --> <!-- or follow up with an issue comment of `@gitlab-bot label ~"reproduced on GitLab.com"` if you do not --> #### Results of GitLab environment info <!-- Input any relevant GitLab environment information if needed. --> <details> <summary>Expand for output related to GitLab environment info</summary> <pre> (For installations with omnibus-gitlab package run and paste the output of: `sudo gitlab-rake gitlab:env:info`) (For installations from source run and paste the output of: `sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production`) </pre> </details> #### Results of GitLab application Check <!-- Input any relevant GitLab application check information if needed. --> <details> <summary>Expand for output related to the GitLab application check</summary> <pre> (For installations with omnibus-gitlab package run and paste the output of: `sudo gitlab-rake gitlab:check SANITIZE=true`) (For installations from source run and paste the output of: `sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production SANITIZE=true`) (we will only investigate if the tests are passing) </pre> </details> ### Possible fixes <!-- If you can, link to the line of code that might be responsible for the problem. --> ### Patch release information for backports If the bug fix needs to be backported in a [patch release](https://handbook.gitlab.com/handbook/engineering/releases/patch-releases) to a version under [the maintenance policy](https://docs.gitlab.com/policy/maintenance/), please follow the steps on the [patch release runbook for GitLab engineers](https://gitlab.com/gitlab-org/release/docs/-/blob/master/general/patch/engineers.md). Refer to the [internal "Release Information" dashboard](https://dashboards.gitlab.net/d/delivery-release_info/delivery3a-release-information?orgId=1) for information about the next patch release, including the targeted versions, expected release date, and current status. #### High-severity bug remediation To remediate high-severity issues requiring an [internal release](https://handbook.gitlab.com/handbook/engineering/releases/internal-releases/) for single-tenant SaaS instances, refer to the [internal release process for engineers](https://gitlab.com/gitlab-org/release/docs/-/blob/master/general/internal-releases/engineers.md?ref_type=heads). <!-- If you don't have /label privileges, follow up with an issue comment of `@gitlab-bot label ~"type::bug"` -->
