 Expect the prompt to include:
 
 - the incoming issue's number, title, and description
-- a list of recent/open issues with their numbers, titles, and descriptions (provided by the triage workflow or fetched via the GitHub API)
+- the repository owner/name, so you can search issues yourself via the GitHub API or `gh api --paginate`
 
 ## Duplicate detection procedure
 
-1. Normalize the incoming issue's title and description by lowercasing, stripping leading/trailing whitespace, and collapsing runs of whitespace into single spaces.
-2. For each candidate issue in the comparison set:
+1. Enumerate comparison candidates yourself. Fetch all open issues in the repository with pagination, excluding pull requests and the incoming issue itself. Use the GitHub API directly or `gh api --paginate`; do not rely on a preselected candidate list from the triage prompt and do not cap the search to the newest issues.
+2. Fetch closed issues only when they were closed within the last 7 days or when repository-specific guidance names a known canonical duplicate. Older closed issues should generally not be treated as duplicates because they may already be resolved.
+3. Normalize the incoming issue's title and description by lowercasing, stripping leading/trailing whitespace, and collapsing runs of whitespace into single spaces.
+4. For each candidate issue in the comparison set:
    a. Compute title similarity: compare the incoming title to the candidate title. Consider them title-similar when they share the same core noun phrases or intent after stripping common prefixes like "bug:", "feature:", "[request]", emoji, and markdown formatting.
    b. Compute description similarity: compare the key symptoms, error messages, reproduction steps, and requested behavior between the incoming and candidate descriptions. Ignore boilerplate template sections (e.g., "## Environment", "## Steps to Reproduce" headers with empty content) that do not carry diagnostic signal.
    c. A candidate is a likely duplicate when **both** of the following hold:
       - The titles convey the same problem, feature request, or question (not merely sharing a common keyword).
       - The descriptions overlap on at least one substantive detail: a shared error message, the same failing behavior, the same requested capability, or an equivalent reproduction scenario.
-3. Rank candidates by overall similarity (title weight ≈ 40%, description weight ≈ 60%) and select the top matches.
-4. Only flag an issue as a duplicate when **2 or more** existing issues are identified as likely duplicates. A single weak match is not sufficient — the evidence must be corroborated across multiple existing issues to reduce false positives.

 ## Guidelines
 
 - Prefer precision over recall. It is better to miss a borderline duplicate than to incorrectly flag a unique issue.
-- Do not consider issues that are already closed as duplicates unless they were closed very recently (within the last 7 days) — older closed issues may have been resolved and reopening them is not helpful.
 - Ignore the incoming issue itself when scanning candidates.

+## Cloud workflow mode
+
+Duplicate detection is invoked from the cloud-mode triage workflow,
+so the same artifact-upload contract applies whenever the prompt
+delegates here. When you populate the `duplicate_of` field in the
+triage result, do so within the same JSON document the triage
+workflow's prompt asks you to upload via `oz artifact upload
+triage_result.json` (or `oz-preview artifact upload
+triage_result.json` when the `oz` CLI is not available). Do not write
+the result to a `/mnt/...` mount path; the cloud agent has no such
+mount, and the host workflow only reads what you upload through the
+artifact CLI.
