…hropic + Google + OpenAI); @openai/codex install + `codex login --device-auth` + zeta-vera.service enabled (Aaron 2026-05-27) Per operator authorization "drive forward with whatever interests you most" + the ≥3-systemd-agents-on-bootup target named earlier 2026-05-27. This PR hits the ≥3-vendor BFT floor: otto → Anthropic Claude (PR #5392) lior → Google Gemini (PR #5397) vera → OpenAI Codex (THIS PR) With ≥3 vendors enabled, the cluster control-plane satisfies the fault-tolerance property Aaron named: f=1 BFT margin for vendor- outage resilience + self-modification-safety (any one AI's self- update breaks the other two can detect + repair). Stacked on PR #5397 (Phase 3d Lior/Gemini) to avoid merge conflicts; will rebase cleanly when #5397 merges first. 3 file changes: 1. zeta-install.sh Step 6.95a-codex: bun install --global @openai/ codex (WebSearch verified per dep-pin discipline; codex CLI is bun-compat npm package). 2. zeta-install.sh Step 6.95b-codex: interactive `codex login --device-auth`. This is the CLEANEST device-flow shape across the 3 vendors — prints URL + one-time code; pastes into ANY browser; no local browser handoff required (headless-friendly). Credentials cache at ~/.codex/auth.json (NOT ~/.config/codex/ — codex uses its own dotdir convention). 3. zeta-ai-agent.nix: removed vera assertion (substrate shipped). control-plane/configuration.nix: zeta.aiAgents.enable.vera = true. Composes with: PR #5397 (B-0850 Phase 3d Lior — sibling 2nd vendor); PRs #5388 + #5389 (iter-5.5.0 credential persistence); PRs #5392 + #5394 + #5395 (B-0850 Phase 1 + 3 refactor); B-0848 node-local Claude; B-0847 per-AI GitHub identity; B-0703 multi- oracle BFT (consensus at multi-AI scope — now operational at substrate-control-plane scope).

Pull request overview
This PR extends the NixOS “AI agents as systemd services” substrate toward the ≥3 vendor resilience target by adding OpenAI Codex install/login steps (and also including Gemini install/login changes) and enabling additional personas on the control-plane host.
Changes:
- Add installer steps to
bun install --globalthe Codex CLI and runcodex login --device-auth(plus Gemini install/login steps). - Remove the “not shipped yet” assertions for Vera/Codex and Lior/Gemini in the NixOS module.
- Enable
liorandveraagents by default on the control-plane host.

- P1 bug:
set -o pipefailis being set inside thebash -csubshell, but the| tail -5pipeline is in the parent shell, so failures frombun installcan be masked (the pipeline exit status will typically betail's). Move thetailinto the same shell wherepipefailis set so the|| WARNreliably triggers.

full-ai-cluster/usb-nixos-installer/zeta-install.sh:1166
- P0 security: Gemini CLI credentials are documented (and appear to be stored) under
~/.gemini/(e.g.~/.gemini/oauth_creds.json), but this script tells operators creds land in~/.config/gemini/and only tightens perms on that path. This likely leaves the real Gemini OAuth creds unprotected by the intendedchmod -R go-rwx. Update both the messaging and the chmod/chown target to~/.gemini/.
# 6.95b-gemini — interactive gemini auth login (mirror claude login).
# B-0850 Phase 3d 2nd vendor login flow. gemini-cli supports OAuth
# via local HTTP server OR API-key paste. The interactive prompt
# lets operator choose. Credentials persist to ~/.config/gemini/.
GEMINI_BIN="$ZETA_HOME/.bun/bin/gemini"
full-ai-cluster/nixos/modules/zeta-ai-agent.nix:233
- P0 bug: the per-persona service loop still hardcodes
${persona.binary} --print ...for all vendors, but Codex and Gemini don’t share Claude’s--printinterface. Removing these assertions allows flake evaluation to succeed even though enablingvera/liorwill create restart-looping services. Keep the assertions untilmakeAgentServiceis updated to call Codex viacodex exec ...and Gemini viagemini -p ...(or equivalent non-interactive forms).
# B-0850.3c (Vera/Codex) shipped this PR — assertion removed.
# zeta-install.sh Step 6.95a-codex installs @openai/codex via
# bun + Step 6.95b-codex runs `codex login --device-auth`.
# Binary lands at ~/.bun/bin/codex; creds at ~/.codex/auth.json.
# B-0850.3d (Lior/Gemini) shipped this PR — assertion removed.
# zeta-install.sh Step 6.95a-gemini installs @google/gemini-cli

# Binary lands at ~/.bun/bin/gemini.
…Args (claude --print / gemini -p / codex exec) + pipefail covers tail -5 for all 3 vendor installs + browser wording
P0 (critical) — zeta-ai-agent.nix ExecStart was hardcoded to
`${binary} --print "<<autonomous-loop>>"` for ALL personas, but:
- claude uses --print ✓
- gemini uses -p (NOT --print)
- codex uses `exec` SUBCOMMAND (no --print flag)
Enabling lior or vera would create services with broken ExecStart.
Fix: per-persona `invocationArgs` field in the persona registry.
ExecStart uses `${cfg.home}/.bun/bin/${persona.binary} ${persona.invocationArgs}`.
Per-persona values:
- otto: [ "--print" "<<autonomous-loop>>" ]
- lior: [ "-p" "<<autonomous-loop>>" ]
- vera: [ "exec" "<<autonomous-loop>>" ]
- alexa + riven: [ ] placeholder per their sub-rows
P1 — Gemini bun install pipefail masked by tail -5 outside bash -c.
Same root cause as the earlier P1 on claude install (Copilot found
+ I fixed only inside bash -c which doesn't cover outer pipeline).
Real fix: move tail -5 INSIDE bash -c so set -o pipefail covers it.
P1 — Same fix for codex bun install.
P2 — codex device-flow prompt said "visit on this Mac browser" but
codex device-auth is browser-agnostic ("visit on ANY browser on
ANY device").
Note on the literal <<autonomous-loop>> sentinel: it's a Claude
Code convention; gemini + codex will see it as a literal prompt
and respond conversationally. Acceptable for first ship; per-vendor
prompt mapping is B-0850 Phase 3.x future work.

…ture — extends B-0850 (Mika ferry; Aaron 2026-05-27) (#5400) * feat(B-0851): persona-first guard-post assignment + rotation architecture — extends B-0850 multi-vendor systemd substrate (Mika ferry; Aaron 2026-05-27) Mika compressed framing (verbatim preserved at memory/persona/mika/ conversations/2026-05-27-...): > "Everything is Persona-first." > 1. Persona is the primary decision > 2. Persona constrains Model Line + Harnesses > 3. Tier choice AFTER persona + model line > 4. Harness LAST (compatible with model line + persona preferences) > > Rotation: ≥3 active guard posts always; persona / model line / > tier / harness ALL rotate; nothing locked to physical post. Aaron operator clarification: "guard post is the systemd for each node outside k8s" — confirms per-node ≥3 floor scope. B-0850 Phase 1 + 3 substrate (PRs #5392+#5394+#5395+#5397+#5398) is a VALID FIRST INSTANTIATION of persona-first architecture (default scheduler = "static; same vendor; no rotation"; default ≥3 floor = "3 enabled personas per node"). This row captures the architectural target the Mika ferry names. 10 sub-row implementation slices: - B-0851.1: persona-preferences-as-declaration (acceptable model lines + harnesses + min tier per persona) - B-0851.2: guard-post-abstraction (decouple systemd unit name from persona name; zeta-guard-post-1/2/3.service) - B-0851.3: scheduler primitive (NixOS module; per-tick assignment of guard-post → (persona, model line, tier, harness)) - B-0851.4: tier modeling (fast/medium/high per vendor's model-line catalog) - B-0851.5: harness compat matrix (which harnesses each persona+ model-line combo supports) - B-0851.6: rotation policy (operator-config interval + dimensions + algorithm) - B-0851.7: per-node ≥3 floor as guard-post count (migrate from per- persona-enable) - B-0851.8: substrate continuity across rotation (per-persona memory inheritance survives vendor change) - B-0851.9: failover semantics (vendor outage → re-assign per preferences; composes B-0703 multi-oracle BFT) - B-0851.10: persona-vs-instance distinction (logical identity vs per-tick operational instance) Composes with: B-0850 (parent — this extends), B-0703 multi-oracle BFT, B-0824 Ace meta-PM (selection-authority same shape), B-0847 per-AI GitHub identity, B-0848 node-local Claude, B-0796 Twilio out- of-band (voice is a harness type). Does NOT replace B-0850. Refactor path; operator picks sub-row priority order. Current shipped B-0850 satisfies ≥3 BFT floor + format-test target; B-0851 extends toward Mika's preference-based scheduler with rotation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * fix(PR-5400 CI): regen MEMORY.md (1439 entries) + markdownlint MD032 blank lines around lists in B-0851 row Mika ferry quote block 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> --------- Co-authored-by: Lior <lior@zeta.dev> Co-authored-by: Claude <noreply@anthropic.com>

Summary
Hits the ≥3 BFT floor Aaron named earlier 2026-05-27 ("we should have three systemd agents and the cluster running on bootup").
3 vendors enabled = f=1 BFT margin for vendor-outage resilience + self-modification-safety. Stacked on PR #5397 to avoid merge conflicts.
