+
+**Values:** `skill-pack`, `software`, `directory`, `mirror`, `uncertain`. File counts do not decide these values.
+
+**Use for:** recorded machine evidence and holding new directory or mirror admissions for human review.

+# Repository purpose
+
+Jev reads repository purpose from bounded source evidence at one Git commit.
+The stored finding covers organizations and individual maintainers.
+It records directories, mirrors, original Skill packs, software, and uncertain evidence separately.
+
+## Read a finding
+
+```sql
+SELECT owner,repo,purpose,probability,reason,model,source_commit,prompt_version,evaluated_at
+FROM repository_purpose
+WHERE owner='posthog' AND repo='posthog';
+```
+
+The `evidence` column holds description, README excerpt, path samples, Skill excerpts, and measured counts.
+Counts are null when GitHub truncates the tree. A partial tree never proves a full count.
+The `answer` column preserves the typed model answer and option probabilities.
+The reason comes from the selected criterion or an explicit uncertainty rule. Jev does not generate prose.
+
+## Admission
+
+New directory, mirror, and uncertain findings require human review before the ingestion reads all Skill contents.
+Existing Skills, eligible human decisions, and verified Owners retain the existing admission path.
+Software and Skill-pack findings continue through the existing rules. They earn no new trust or SEO indexing.
+Use the existing repository review surface to admit a held repository. Do not edit the machine finding as approval.
+
+The default Skills directory retains its separate `skill_repo_focus` screen.
+Repository purpose does not replace that screen or the `repo_kind` field.
+
+## Refresh
+
+The hourly task dispatches up to 25 durable classification jobs.
+It prioritizes truncated trees, large Skill inventories, and repositories with stored Skills.
+It includes metadata-only repositories with detected Skills, including held large inventories.
+The task avoids active jobs and waits one day after a failed job.
+
+A changed source commit or prompt version invalidates the cached model answer.
+Findings expire after seven days, so an unchanged source still receives periodic model checks.
+The source reader uses one recursive tree request. It never expands a truncated tree.
+It streams bounded prefixes from the README and two representative Skills at the same source commit.
+Provider or source failures retry through the durable queue. Missing purpose evidence records `uncertain`.
+An uncertain result never becomes permission to admit a repository.
+
+## Evaluate a prompt
+
+Prepare a JSON array with `name`, `expected`, and `evidence` for each case.
+The evaluator parses each evidence object against the same source limits.
+Use public source snapshots and keep reports outside the repository.
+
+```sh
+pnpm exec tsx scripts/evaluate-repository-purpose.ts INPUT.json OUTPUT.json
+```
+
+Set `CLOUDFLARE_ACCOUNT_ID` and `CLOUDFLARE_API_TOKEN` with Workers AI Read access.
+Or pass `--binding` to use Wrangler's authenticated remote Workers AI binding.
+The evaluator records answers and source evidence. It writes no database rows.
+Include a large application, small directory, original Skill pack, mirror, single root Skill, and uncertain evidence.
+Include source text that tries to instruct the model. Check that it stays evidence.
+If a prompt changes, update `REPOSITORY_PURPOSE_PROMPT_VERSION` and repeat the eval before delivery.
+
+## Cull
+
+A machine finding never removes existing Skills.
+Use existing human admission and Skill indexability procedures to remove an unsuitable surface.
+Keep the human reason separate from the machine evidence.

 ## Admission
 
 New directory, mirror, and uncertain findings require human review before the ingestion reads all Skill contents.
-Existing Skills, eligible human decisions, and verified Owners retain the existing admission path.
+Existing Skills, eligible human decisions, named positive trust overrides, and verified Owners retain the existing admission path.
 Software and Skill-pack findings continue through the existing rules. They earn no new trust or SEO indexing.
-Use the existing repository review surface to admit a held repository. Do not edit the machine finding as approval.
+The leaderboard review surface covers individual Owners with discovered inventory.
+Use the query below for held findings outside that surface, including organizations and new submissions.
+Do not edit a machine finding as approval.
+
+```sql
+SELECT p.owner,p.repo,p.purpose,p.reason,p.evidence,p.source_commit
+FROM repository_purpose p
+WHERE p.purpose IN ('directory','mirror','uncertain')
+  AND NOT EXISTS(SELECT 1 FROM skills s WHERE s.owner=p.owner AND s.repo=p.repo)
+  AND NOT EXISTS(SELECT 1 FROM skill_repo_eligibility e
+    WHERE e.owner=p.owner AND e.repo=p.repo AND e.status='eligible')
+  AND NOT EXISTS(SELECT 1 FROM repo_trust_overrides t
+    WHERE t.owner=p.owner AND t.repo=p.repo
+      AND t.tier IN ('official','trusted-author','trusted-curator')
+      AND length(trim(t.reviewed_by))>0 AND length(trim(t.reason))>0)
+ORDER BY p.evaluated_at;
+```
+
+If a human approves source admission, record an existing positive `repo_trust_overrides` decision through a reviewed migration.
+Set the actual reviewer, reason, source, and review time. This decision permits source admission for the whole Repository.
+Use `trusted-curator` only when the human approves that trust level. Keep rejected findings held.
+After the migration deploys, submit the Repository again through the search box or `POST /api/repos/index`.
+The new job checks the human decision before calling Jev. The decision never changes the machine finding.
 
 The default Skills directory retains its separate `skill_repo_focus` screen.
 Repository purpose does not replace that screen or the `repo_kind` field.
