S00-031: Approve the independently verified Codex host sandbox diagnostic

Changes: Accept S00-031 with independent QA evidence and handoff; confirm the automation guidance matches the bounded host-context diagnostic.
Validation: Approved host stat verified uid1000/mode0700; inner workspace-write probe exited 0 with project write/read/remove and outside write denial EROFS30. make check passed 72 tests; scope, executor message and git diff --check passed. No model or storage task ran; acceptance covers this host/version and one filesystem boundary.

 S00-031 outcome implemented, awaiting review. Independently approved outer host execution confirmed directory uid1000/mode0700 and ran one no-model inner workspace-write probe: exit0, project write/read/remove passed, /home/tola exclusive-create denied EROFS30, no outside file created. Outer restricted-shell stat sees mode000, consistent with supplied mask diagnosis. Socket permissions/config/writable roots unchanged; no model/storage task launched.
 
 Source change only docs/AUTOMATION.md. Full inspected probe and exact host wrapper: state/evidence/S00-031-auto-ci-cd-d45ccd3ee7d6.md. Final make check passed all72 tooling tests; initial verbose draft caused prompt-budget errors, fixed by compacting documentation. QA must inspect diff/message, independently request approved outer host execution of the bounded inner sandbox wrapper, verify metadata and both filesystem results, then review only S00-031. Do not execute the probe directly unsandboxed, mutate sockets, or start downstream storage work. Temporary script may be inspected/recreated from evidence; no permanent script dependency. Coordinator owns commit and next fresh process.
