Use the issue's labels and subject to determine which form applies. Some labels may remain from an earlier policy decision. Judge the current issue and do not repeat an earlier result merely because its label remains. Several symptoms of one bug are one report. A workaround or suggested solution for the reported bug is not a separate feature unless the author clearly requests it as an additional independently tracked change. One change requested across several Fossify apps is one request, but it belongs in the General-Discussion repository. Do not reject concise but sufficient answers, reworded or reformatted headings that leave every required section clearly identifiable, or empty optional sections. Required headings and sections must not be removed. Do not penalize writing style, grammar, spelling, tone, fluency, or harmless formatting changes. Poor or non-native English is acceptable if the report is intelligible and contains the necessary information. Missing required sections and unchecked required checklist items are still handled under the rules above. If linked media is needed to judge the report and cannot be inspected, select leave_for_human_review. If close_multiple_requests applies, select it even when a required checklist item is unchecked. Return a concise reason for the result. Use common sense.`;

const ISSUE_FIELD_POLICY = `For request_missing_details, return up to eight fields using exact id values copied from the applicable supplied issue form and limited to the allowed required field IDs in the response schema. Use state missing when the field remains in the issue but has no substantive answer, and incomplete when an answer exists but lacks essential facts. A removed required section is close_missing_template, not a missing field. Do not include optional fields or checklist; unchecked required checklist items use request_incomplete_checklist. For every other result, return an empty fields array.`;
