S00-030: Record blocked task and remediation handoff

Changes: Preserve incomplete work and blocker metadata for S00-030. This checkpoint does not mark implementation accepted.
Validation: Session ended with status blocked.
Blocker: S00-030 no-model sandbox diagnostic still exits 1 before execution with the original socket directory ownership/mode guard, despite XDG_RUNTIME_DIR being user-owned mode 0700. Actual socket directory repair requires host owner input.
Automatic blocker limit reached; explicit external resolution required.

+## Cause
+
+S00-030 no-model sandbox diagnostic still exits 1 before execution with the original socket directory ownership/mode guard, despite XDG_RUNTIME_DIR being user-owned mode 0700. Actual socket directory repair requires host owner input.
+Automatic blocker limit reached; explicit external resolution required.
+
+## One remediation outcome
+
+Host owner supplies a verified valid actual app-server socket directory and a fresh no-model Codex sandbox probe passes under unchanged project write restrictions.
+
+## Evidence / reproduction
+
+Run codex -c sandbox_mode="workspace-write" -c sandbox_workspace_write.network_access=true sandbox -- python3 -c <synthetic probe>; exit 1: app-server socket directory must be a user-owned directory with mode 0700. See state/evidence/S00-030-auto-ci-cd-d37c9faf28f3.md.
+
+The reporting agent must stop now. A new agent implements only S00-031.

+# S00-030 socket environment diagnostic — blocked
+
+Executor: auto-ci-cd-d37c9faf28f3 (ci-cd), 2026-10-15.
+Input: assigned S00-030 card/packet, master/workflow/role instructions, all required task reads, S00-028 evidence and accepted S00-002 ADR/evidence/review/handoff. Intended output: supported private host socket setup and a no-model restricted filesystem probe. No product/source/documentation changes made; no additional model or storage task executed.
+
+## Actual commands and results
+
+- `python3 scripts/tasks.py resume --agent auto-ci-cd-d37c9faf28f3`, `show S00-030`, and `packet S00-030 --agent auto-ci-cd-d37c9faf28f3`: exit 0 each; assigned in_progress, no repeated claim.
+- Required input reads succeeded. Batched `cat` exited 1 solely because optional previous `state/handoffs/S00-030.md` did not exist for this fresh remediation. No required artifact was missing.
+- `command -v codex`: exit 0, `/home/tola/.local/bin/codex`.
+- `codex sandbox --help`: exit 0; local CLI supports no-model command execution. Warning: PATH aliases could not be created on read-only filesystem.
+- Python selective runtime-directory inspection: exit 0; process uid 1000, XDG_RUNTIME_DIR=/run/user/1000, directory uid 1000 and mode 0700. This does not establish the actual app-server socket directory.
+- Python subprocess with 20-second timeout invokes `codex -c 'sandbox_mode="workspace-write"' -c sandbox_workspace_write.network_access=true sandbox -- python3 -c '<probe>'`: child exit 1, wrapper exit 1, before any probe output. Exact error: `error building bubblewrap command: app-server socket directory must be a user-owned directory with mode 0700`.
+
+Probe body would exclusively create/read/remove `state/evidence/.S00-030-sandbox-probe` with synthetic text, then attempt an exclusive-create sibling `.S00-030-denied-probe`, require EACCES/EPERM/EROFS, and remove an unexpectedly created file before failing. Neither probe executed; no filesystem restriction check is claimed passed. No permission broadening, socket ownership/mode mutation, sandbox bypass, config change or Git mutation occurred.
+
+## Blocker
+
+The supplied host environment still fails the exact original socket-directory guard. XDG_RUNTIME_DIR alone is correctly private but is insufficient. The host/coordinator must identify the actual app-server socket directory used by this CLI, correct its user ownership/private mode through the supported host lifecycle, and provide nonsecret confirmation to a fresh process. No valid supported setup can be documented or accepted from this failed diagnostic. Requires external owner input; source edits stopped.

+# S00-030 handoff — external socket environment still invalid
+
+Executor: auto-ci-cd-d37c9faf28f3 (ci-cd). No source changes or additional model/storage execution.
+
+Bounded no-model `codex -c 'sandbox_mode="workspace-write"' -c sandbox_workspace_write.network_access=true sandbox -- python3 -c '<synthetic filesystem probe>'` failed before command execution, exit 1: `error building bubblewrap command: app-server socket directory must be a user-owned directory with mode 0700`.
+
+XDG_RUNTIME_DIR=/run/user/1000 is already uid 1000/mode 0700 and current uid is 1000; this does not identify the actual failing socket directory. No write/read/remove or denial check ran. Evidence: state/evidence/S00-030-auto-ci-cd-d37c9faf28f3.md.
+
+Next input: host/coordinator identifies the actual socket directory used by installed Codex, repairs its ownership/mode through the supported host lifecycle, and supplies nonsecret confirmation. New resolver process must run the bounded no-model probe with original project restrictions intact and document only the verified setup in docs/AUTOMATION.md. No broadening writable roots or sandbox bypass. Reporter ends after escalation; coordinator owns further sessions.
