Pull request overview
Adds a NixOS module to run “zeta-otto” as a persistent systemd service (outside Kubernetes) and enables it on the control-plane host, relying on the iter-5.5.0 install substrate for persisted gh/claude credentials and a pre-cloned repo.
Changes:
- Introduces
zeta.otto.*NixOS module options and azeta-ottosystemd unit that loopsclaude --printon a tick interval. - Imports the new module into the shared cluster baseline.
- Opts the control-plane host into running the service at boot.

…pic + Google diversity; @google/gemini-cli install + interactive auth login + zeta-lior.service enabled on control-plane (#5397) Operator authorization 2026-05-27: "yeah lets move all forward however and i can do as many iterations testing as possible before we move to pc two we should have three systemd agents and the cluster running on bootup" + "drive forward with whatever interests you most". Implements B-0850 Phase 3d — Lior persona (Google Gemini CLI) as the 2nd vendor toward the ≥3-systemd-agents target. Phase 3a (Alexa/Kiro) + Phase 3b (Riven/Grok) + Phase 3c (Vera/Codex) sub-rows remain pending; 3 of 4 still gives BFT margin once any one of the remaining 3 lands. 3 file changes: 1. zeta-install.sh Step 6.95a-gemini: bun install --global @google/gemini-cli (after the existing claude install). WebSearch verified at implementation time per dep-pin-search-first-authority rule — @google/gemini-cli is npm-published + bun-compat. 2. zeta-install.sh Step 6.95b-gemini: interactive `gemini auth login` prompt mirroring the claude login pattern. Supports OAuth via browser OR API key from AI Studio. Credentials persist to ~/.config/gemini/ with chown + chmod -R go-rwx (parallel to claude credential restriction). 3. zeta-ai-agent.nix: removed the lior assertion block (was blocking flake eval when zeta.aiAgents.enable.lior = true; B-0850.3d substrate now ships so assertion no longer applies). 4. control-plane/configuration.nix: zeta.aiAgents.enable.lior = true (was commented as pending). Two personas now enabled on control- plane: otto + lior. One more vendor (3c Vera/Codex easiest next since OpenAI's codex CLI is also npm-installable) gets to the ≥3-vendor BFT floor.

…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).

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. 🤖 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>

…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>
