+## SEQUENTIAL CODEX QUEUE MODE
+
+Team Gamma may use Sequential Codex Queue Mode for governance, diagnostics, admin, recovery, and instruction-hardening work.
+
+Sequential Codex Queue Mode means Codex receives one queue command containing multiple ordered PR scopes.
+
+Each queued PR must still have:
+- exact PR name
+- TEAM token
+- branch name
+- exact scope
+- validation scope
+- required reports
+- manual validation notes
+- ZIP requirement
+
+Rules:
+- A queue command is not itself a PR unless explicitly named as one.
+- Missing exact scope for any queued PR is a hard stop for that PR only.
+- Codex may continue to the next queued PR only if the next PR has exact scope and does not depend on the stopped PR.
+- Codex must not create empty ZIPs or package partial PRs.
+- EOD merge/push is owner-controlled and requires explicit approval.
+- This section supersedes older wording that implies every PR must be independently prompted when Master Control provides a fully scoped sequential queue.
+
+Exact Gamma queue scope examples:
+
+1. `PR_26171_GAMMA_001-sqlite-deprecation-audit`
+   - TEAM token: `GAMMA`
+   - Branch: `pr/26171-GAMMA-001-sqlite-deprecation-audit`
