+### Test actor permissions
+
+Pool orgs grant three test actor accounts specific access levels for
+e2e testing of permission-sensitive behaviour:
+
+| Actor | Org membership | Repo permission on base `test-repo*` |
+|-------|----------------|--------------------------------------|
+| `fstest-write` | member | push (write) |
+| `fstest-triage` | member | triage |
+| `fstest-outsider` | none | public read only (no collaborator grant) |
+
+Elevated access uses direct collaborator grants (not team membership). Fork repos
+(`test-repo-fork`) are intentionally excluded — they are not base/enrolled
+targets for permission grants.
+
+The setup script (`hack/setup-new-e2e-org.sh`) creates or verifies this
+model idempotently. To auto-accept org membership invitations, pass the
+actor PATs as environment variables:
+
+```bash
+TEST_ACTOR_WRITE_PAT=ghp_... TEST_ACTOR_TRIAGE_PAT=ghp_... \
+  MINT_PROJECT=... MINT_FUNCTION=... hack/setup-new-e2e-org.sh 07
+```
+
+Without the PAT variables, the script pauses for manual acceptance.
+
+Accounts and PATs are managed under
+[#6024](https://github.com/fullsend-ai/fullsend/issues/6024). PATs are
+stored as repository secrets `TEST_ACTOR_WRITE_PAT`,
+`TEST_ACTOR_TRIAGE_PAT`, and `TEST_ACTOR_OUTSIDER_PAT` on
+`fullsend-ai/fullsend`.
