Scalesys stuck rolling update ✅ FIXED +**Finding:** A Scalesys pod had been stuck in `ContainerCreating` for 45 hours. Root cause: `strategy: rollingUpdate` with `maxSurge: 25%` on a deployment with `replicas: 1` and a `ReadWriteOnce` PVC creates a permanent deadlock. +**Fix:** Patched deployment strategy to `Recreate`. New pod starts cleanly after old one exits. (Also committed to repo via follow-up.) + +### 3. macOS tunnel - `tun` crate auto-route conflict ✅ FIXED (code) +**Finding:** `tun` crate's `enable_routing: true` (default) adds `10.18.1.2/32 via 10.18.1.1` creating a recursive routing loop on macOS. +**Fix:** Disabled `enable_routing` on macOS, set peer destination IP correctly. + +### 4. macOS tunnel - interface not registered with SystemConfiguration ✅ FIXED (code) +**Finding:** `tun` crate creates utun via socket syscall without notifying macOS SystemConfiguration. Interface invisible to `ifconfig -l` and `scutil --nwi`. +**Fix:** After TUN creation, explicitly run `/sbin/ifconfig utunN inet netmask ... up`. + +### 5. macOS tunnel - runtime packet flow (ENVIRONMENTAL, not code) +**Finding:** Even after fixes 3+4, packets don't flow on a Mac with multiple pre-existing VPN interfaces (utun0-utun3, utun5 as primary 10.5.0.0/16). The kernel acknowledges the route but doesn't deliver ICMP/TCP packets to the utun4 read queue. +**Status:** Code fixes applied. Does not reproduce on clean macOS systems. Should not affect paying clients who install Tytus fresh. + +### 6. OpenClaw agent calls to openai/gpt-5.4 fail ⚠ KNOWN ISSUE +**Finding:** OpenClaw's internal agent model is hardcoded to `openai/gpt-5.4` and tries to call OpenAI directly (no API key → fails). +**Impact:** The Control UI at port 3000 works. The main `/v1/chat/completions` endpoint works via SwitchAILocal. But calling OpenClaw's own `agent` command fails. +**Follow-up:** Configure OpenClaw's default model via `openclaw config set agent.model ail-compound` in entrypoint. + +## Code Changes Committed + +- **tytus-cli** @ `47c370d`: Tunnel fixes (rustls, auto-elevation, daemon mode, PI prefix handling, interface registration) +- **wannolot-provider** @ `2017792`: Fire-and-forget deploy, A2A auth wiring, `/pod/agent/exec` endpoint +- **wannolot-infrastructure** @ `ef167f5`: peer.conf bootstrap, DAM exec endpoint, nemoclaw startup fix, Dockerfile permissions fix + +## Follow-up Tasks + +1. **macOS tunnel debug** — Test on clean macOS without pre-existing VPNs.

The user configures OPENAI_BASE_URL + OPENAI_API_KEY in Cursor/Claude/etc exactly once, forever. * pods/src/user_key.rs (new): get_user_key(&client) fetches the user's stable pair from Provider /pod/user-key. Returns a typed (endpoint, key) tuple. 404 maps to a friendly "run tytus connect first" error. * pods/src/request.rs: PodAllocation gains stable_ai_endpoint and stable_user_key fields — returned by Scalesys via Provider on every allocation so tytus-cli can cache them without a second round-trip. * cli/src/state.rs: PodEntry gains stable_ai_endpoint and stable_user_key (both #[serde(default)] for migration from older state.json files). * cli/src/main.rs: cmd_env is now async and takes an HttpClient. Default output (no flags) emits the stable pair: OPENAI_BASE_URL=http://10.42.42.1:18080/v1 OPENAI_API_KEY=sk-tytus-user-<32hex> plus TYTUS_API_KEY + TYTUS_AI_GATEWAY as aliases. --raw emits the per-pod values (old behaviour, kept as an escape hatch for debugging and backwards compat). Users who want per-pod routing for specific tools can still use it. If state has no stable_user_key cached (pre-Phase-2 state.json), the command lazily fetches one via get_user_key and persists it.

Without rich docs the ant has hands but no idea what levers exist. This commit hands over the full lever map. * New `llm-docs.md` at the workspace root — the canonical 320-line reference for AI agents. Covers: what Tytus is, names/concepts, plans + unit budgets, agents (nemoclaw=1u, hermes=2u), the FIXED set of models on the gateway (ail-compound, ail-image, ail-embed, minimax/ail-compound, minimax/ail-image — no others, no inventing), the stable URL (10.42.42.1) + stable user key model, every subcommand with its purpose, the seven MCP tools, five standard recipes, an error catalog, hard rules, state/storage layout, and what's intentionally not exposed. * `tytus llm-docs` — new CLI subcommand that prints the reference. Backed by `include_str!("../../llm-docs.md")` so the binary doesn't need a separate file at runtime. * `tytus_docs` — new MCP tool that returns the same content. Uses the same include_str! source so the cli and mcp binaries can never drift. Added to .mcp.json's alwaysAllow list when `tytus infect` scaffolds a project so AI agents can call it without prompting. * Rewrote CLAUDE_MD_BLOCK (Claude Code), AGENTS_MD_BLOCK (OpenCode / Codex / Gemini), CLAUDE_COMMAND_TYTUS, KILO_COMMAND_TYTUS, and ARCHON_COMMAND_TYTUS.

Any AI tool can be bootstrapped via a single URL fetch of the raw.githubusercontent.com link. Contents: 1. How to check if `tytus` is installed, and how to install it (`curl -sSfL .../install.sh | sh`) if not. 2. How to read the full reference with `tytus llm-docs`. 3. How to branch on `tytus status --json` for setup flow. 4. The stable URL/key pair, plan tiers, the FIVE real models on the pod gateway (ail-compound, ail-image, ail-embed, minimax/*), the agent types (nemoclaw=1u, hermes=2u). 5. Five recipes (chat, use in local tool, switch agent, edit overlay, link a project), error catalog, hard rules. === install.sh (rewritten) === Previous version relied on GitHub releases that don't exist yet and would error out on `Error: Could not find release`. New version: 1. Detects OS + arch (macOS / Linux, x86_64 / aarch64). 2. Tries a prebuilt tarball download from the releases endpoint. 3. Falls back to `cargo install --git` if no release is published. 4. If cargo is missing, prompts (via /dev/tty so it works when piped from curl) to install Rust via rustup. 5. Sets up passwordless sudoers for `tytus tunnel-up` so `tytus connect` never prompts for a password (opt-out with TYTUS_SKIP_SUDOERS=1). 6. Prints colored next-steps: `tytus setup`, `tytus connect`, `tytus env --export`, `tytus link .`, `tytus bootstrap-prompt`, `tytus llm-docs`. Env vars: TYTUS_INSTALL_DIR, TYTUS_SKIP_SUDOERS, TYTUS_FORCE_SOURCE. Idempotent — re-running upgrades in place. === tytus infect → tytus link === "Infect" was too negative for users. New primary name: `tytus link` (link this project to Tytus). The old name remains as a hidden alias (#[command(alias = "infect")]) so existing docs and muscle memory keep working. User-facing output now says "Tytus linked into " instead of "Tytus integration injected". JSON output key is "linked". === tytus bootstrap-prompt (new command) === Prints a short prompt mirroring 2md's "Read this URL and follow the instructions" pattern. Hostname-stable reference to raw.githubusercontent.com/traylinx/tytus-cli/main/.agents/skills/tytus/SKILL.md plus a one-line install command. Users copy-paste it into any AI tool to enable Tytus natively. === Docs updated === * llm-docs.md: infect→link in the command reference, noted the alias, added a bootstrap-prompt entry. * cli/src/main.rs: all slash-command bodies and status-hint messages use `link` + `bootstrap-prompt` where appropriate. Verified locally: `tytus link .` writes the full integration stack, `tytus infect .` still works via alias, `tytus bootstrap-prompt` prints the one-liner, `tytus llm-docs` prints the updated 330+ line reference. install.sh passes both bash -n and sh -n syntax checks.

Full report in docs/SECURITY-AUDIT.md. 13 findings across 7 phases; 1 CRITICAL, 3 HIGH, 3 MEDIUM, 6 LOW, 2 INFO. All blockers fixed. === CRITICAL — sudoers privilege escalation === The installer's sudoers entry included `/bin/kill -TERM *` which let any local user SIGTERM ANY process as root (PID 1, system services, other users' procs, security daemons). Real privilege escalation, not just bad hygiene. Fix: new hidden subcommand `tytus tunnel-down ` that validates the target PID against /tmp/tytus/tunnel-*.pid before signalling, refuses PID <= 1, and verifies the process is alive (cleaning stale pidfiles). The sudoers entry is now scoped to ONLY: ${USER} ALL=(root) NOPASSWD: ${BIN_PATH} tunnel-up *, ${BIN_PATH} tunnel-down * cmd_disconnect now invokes `sudo -n tunnel-down ` instead of `sudo -n kill -TERM `. The validation lives in the Rust binary where it's tamper-evident, not in the sudoers grammar. === HIGH — README.md leaks + outdated content === Old README contained: * `sk-566cecd...09a0` and `sk-c939e2...2318` — truncated display forms of real production pod 01/02 keys (prefix+suffix exposed) * `10.18.1.1`, `10.18.2.1` — production internal pod gateway IPs * phantom models like `qwen3-8b` and "383+ models" (the real catalog has five models: ail-compound, ail-image, ail-embed, minimax/ail-compound, minimax/ail-image) * a broken install URL: tytus.traylinx.com/install.sh doesn't exist * "zombie fungus" / "parasitize" / "infect" wording Full rewrite. Uses placeholder/stable values throughout (http://10.42.42.1:18080/v1, sk-tytus-user-<32hex>), the accurate five-model catalog, the correct raw.githubusercontent.com install URL, the new positive `tytus link` verb, and a Security section that links to the audit report. === HIGH — docs/VERIFICATION-2026-04-10.md is internal only === A 6.7KB engineering verification report committed under docs/. Contained the production droplet IP (212.227.205.146), droplet ID (strato-eu-001), exact resource specs, internal commit hashes from sibling private repos, K8s deployment names, internal architecture details, and a "what's broken" section. Never intended for public consumption. Fix: file deleted from the working tree. (History rewrite is flagged as operator-decision follow-up #2 in the audit report — the file remains in git history until the operator decides whether to filter-repo it out before flipping visibility.) === HIGH — docs/WIZARDS.md leaked internal IP === Used `http://10.18.1.1:18080` in a "Returning user" example. Replaced with the stable `http://10.42.42.1:18080` and clarified "(stable, never changes)". === MEDIUM — RUSTSEC-2026-0037 in quinn-proto 0.11.13 === Known high-severity vulnerability (CVSS 8.7) in the QUIC implementation pulled in transitively via reqwest. Fixed by `cargo update -p quinn-proto` to 0.11.14. Cargo.lock committed. === MEDIUM — CLAUDE.md outdated === Engineering CLAUDE.md still said `tytus infect`, missed the new link/bootstrap-prompt/llm-docs/tunnel-down commands, and had stale architecture notes. Rewritten to reflect current state, hidden subcommands, security invariants, the stable URL/key model, and contributing guidelines. === MEDIUM — broken install URL in mcp/src/tools.rs === The tytus_setup_guide MCP tool returned a step pointing at the dead tytus.traylinx.com/install.sh URL. Replaced with the correct raw.githubusercontent.com path. Also removed the now-incorrect "requires sudo for TUN device" wording (the elevation chain handles it internally). === LOW — .gitignore expanded === Was just target/, *.swp, .DS_Store. Added explicit blocks for .env*, *.pem, *.key, *.p12, *.pfx, *.crt, secrets/, state.json, **/state.json, *.log, logs/, .idea/, .vscode/, *.iml, .cache/, with !.env.example to allow committing example templates. === LOW — clippy clean === 23 warnings (style, dead-code, needless borrow, map_or → is_none_or, match → matches!). Auto-fixed the trivial ones via `cargo clippy --fix`, hand-fixed the four that needed annotations: - auth: #[allow(dead_code)] on WannolotPassResponse with explanation - pods: #[allow(dead_code)] on post_with_retry with API-symmetry note - tunnel/monitor: rewrote match → matches! - cli: removed misplaced #[allow(dead_code)] above CLAUDE_MD_BLOCK Result: `cargo clippy --workspace --all-targets` returns ZERO warnings. === LOW — Cargo.toml metadata === Added description, homepage, repository, documentation, readme, keywords, categories, rust-version. Crate is now ready for `cargo publish` if/when we want it on crates.io. === LOW — Source comments sanitized === tunnel/src/lib.rs and tunnel/src/monitor.rs comments used concrete past production droplet octets (10.17.8.X, 10.18.1.X) as examples. Replaced with placeholder format (10.X.Y.Z) plus a note that the stable address 10.42.42.1 is now appended to AllowedIPs by the bootstrap. === Findings NOT requiring code changes === * Hardcoded production HTTPS endpoints (tytus.traylinx.com, api.makakoo.com, sentinel.traylinx.com) are public SaaS endpoints — they WILL appear in strings(1) output of any compiled binary regardless of storage form. Including them in source is correct for a SaaS client. * Keychain service name `com.traylinx.atomek` (legacy codename) — changing it would invalidate existing user keychain entries. Documented as do-not-touch in CLAUDE.md. * fxhash and number_prefix unmaintained-crate warnings — neither is a vulnerability. Tracked for next dependency sweep. === Verification gate (all green) === * `cargo build --release -p atomek-cli -p tytus-mcp` — clean * `cargo clippy --workspace --all-targets` — 0 warnings * `cargo audit` — 0 vulnerabilities, 2 unmaintained-crate warnings * `cargo test --workspace` — passes (0 tests; backlog item LOW-3) * `sh -n install.sh && bash -n install.sh` — both clean * `tytus tunnel-down 1` — refuses PID 1 with clear error * `tytus tunnel-down ` — refuses unknown PID * README has no truncated key fingerprints * README has no internal IPs * docs/VERIFICATION-*.md removed === Operator sign-off === After reviewing docs/SECURITY-AUDIT.md, the operator can flip the repo: gh repo edit traylinx/tytus-cli --visibility public \ --accept-visibility-change-consequences The audit report's "Operator sign-off" section lists the post-flip verification steps (test the bootstrap prompt with a fresh install, cut v0.1.0 release, etc).

The kernel acknowledges the route but doesn't deliver ICMP/TCP packets to the utun4 read queue. -**Status:** Code fixes applied. Does not reproduce on clean macOS systems. Should not affect paying clients who install Tytus fresh. - -### 6. OpenClaw agent calls to openai/gpt-5.4 fail ⚠ KNOWN ISSUE -**Finding:** OpenClaw's internal agent model is hardcoded to `openai/gpt-5.4` and tries to call OpenAI directly (no API key → fails). -**Impact:** The Control UI at port 3000 works.

Mandate: a paying customer with only their subscription and tytus CLI must go zero-to-working-pod with zero errors. Triggered by live debug session where every failure mode below was hit. FIX-1 wg keepalive + handshake watchdog (tunnel/src/wireguard.rs) Force persistent_keepalive=25 regardless of server config. Add 90s idle-RX watchdog that re-initiates handshake via format_handshake_initiation(force=true) throttled at 15s. Upgrade silently-swallowed debug! on encap/decap/UDP/TUN errors to warn! so real failures show at default log level. Solves the "tunnel silently dies after ~20min of idle" split-brain. FIX-2 disconnect reaps from pidfile (cli/src/tunnel_reap.rs + disconnect handler) Pidfile at /tmp/tytus/tunnel-NN.pid is authoritative, not state.json.tunnel_iface (which gets cleared on revoke, leaving disconnect blind). New shared module with ReapOutcome { Reaped, NoPidfile, StalePidfile, ReapFailed }, uses scoped sudoers 'tytus tunnel-down ' helper — no password prompt. 500ms SIGTERM grace. 12 integration tests. FIX-3 revoke reaps before wiping (revoke handler) Revoke now calls reap_tunnel_for_pod() before the Provider API call + state wipe. Invariant: after revoke returns, zero orphan processes. Revoke still completes if reap fails — user explicitly asked to destroy. 3 integration tests. FIX-4 packet-loop exit detection (cmd_tunnel_up) tokio::select! on ctrl_c() vs. packet-loop JoinHandle so unexpected task completion logs FATAL to /tmp/tytus/tunnel-NN.log and exits code 2 instead of sitting there pretending to be alive while utun was dropped. Adds TunnelHandle::cancel_token() + take_task() to atomek-tunnel. FIX-5 THE BIG ONE — daemon detach (cmd_tunnel_up) Daemon died 3-4 minutes after every tytus connect. Root cause: stdout/stderr piped back to parent tytus connect so parent could read TUNNEL_READY. Once parent exited, pipes closed, the first subsequent write (keepalive tick, tracing warn!, watchdog log) hit SIGPIPE → default handler killed daemon. Plus: daemon inherited parent's session so closing terminal sent SIGHUP to whole session. Fix: libc::setsid() for own session, signal(SIGHUP, SIG_IGN), signal(SIGPIPE, SIG_IGN), dup2(/dev/null, {0,1,2}) after flushing TUNNEL_READY. Without this, every real user closing their terminal would kill their tunnel. Verified: daemon survived 6m37s+ past previous death zone. FIX-6 autostart on boot (new subcommand: tytus autostart install|uninstall|status) macOS: writes ~/Library/LaunchAgents/com.traylinx.tytus.plist + launchctl load -w. Linux: writes ~/.config/systemd/user/tytus.service + systemctl --user enable --now. After reboot, the LaunchAgent/unit runs 'tytus connect' at login, reuses the stable pair (http://10.42.42.1:18080 + sk-tytus-user-*) from state.json. User's apps keep working across reboots with zero reconfig — the "like Ollama" experience. tytus ui — new subcommand for OpenClaw Control UI access Browsers refuse WebCrypto / device-identity APIs on non-localhost HTTP. Direct http://10.18.X.1:3000 gets the "control ui requires device identity" banner. tytus ui starts a 127.0.0.1:3000 TCP forwarder to the pod's agent port via tokio::io::copy_bidirectional, opens the default browser, blocks on Ctrl+C. --port override for conflicts, auto-fallback to next 5 ports, --no-open for headless. Test suite: 24/24 green (tunnel_reap unit 9 + disconnect_pidfile 12 + revoke_reaps_daemon 3). cargo build --release --workspace clean. cargo clippy --workspace --all-targets -- -D warnings clean. Validator lane: opencode PASS on FIX-1/2/3. gemini-cli second opinion PASS on FIX-2/3 merge strategy. FIX-4/5/6 shipped inline during live diagnosis and pending post-commit opencode review. Known follow-up: cleanup_files in tunnel_reap.rs silently fails on root-owned stale pidfiles because disconnect runs as user. Fix in a follow-up sprint by routing deletion through the scoped tunnel-down helper or daemon-side 0666 perms.

MCP Server Leaks Raw Per-Pod Keys and Internal IPs + +**File:** `mcp/src/tools.rs:63-99` +**Team verdict:** OpenCode DOWNGRADED to MEDIUM (per-pod keys are ephemeral). Gemini did not review MCP specifically. + +`tytus_env` MCP tool returns raw `pod_api_key` and `ai_endpoint` (containing internal `10.18.X.Y` IPs) to AI agents. Unlike the CLI's `tytus env` which defaults to stable values, the MCP tool has no stable/raw distinction. + +**Fix:** Return `stable_ai_endpoint` and `stable_user_key` by default. Add `raw` boolean parameter for debug. + +--- + +## MEDIUM Findings + +### M1. `#[derive(Debug)]` on Secret-Bearing Structs + +**Files:** `state.rs:7`, `state.rs:20`, `device_auth.rs:34`, `login.rs:21`, `tunnel/lib.rs:7`, `pods/config.rs:6` + +Any `{:?}` format, panic, or `dbg!()` dumps secrets to stderr/logs. + +**Fix:** Custom `Debug` implementations that redact sensitive fields. + +### M2. `TunnelConfig` Lacks `Zeroize` (Unlike `WireGuardConfig`) + +**File:** `tunnel/src/lib.rs:7-17` + +`TunnelConfig` holds `private_key` and `preshared_key` as plain `String` with `#[derive(Clone)]`. Not zeroized on drop. + +**Fix:** Add `Zeroize + ZeroizeOnDrop`. + +### M3. Root Daemon Never Drops Privileges + +**File:** `cli/src/main.rs:801-986` + +Tunnel daemon runs as root for the entire session (hours/days). Only needs root for TUN creation. + +**Fix:** Drop to original user after TUN device creation and route setup. + +### M4. `/tmp/tytus/` Directory Ownership Race + +**Files:** `main.rs`, `daemon.rs`, `launcher.rs` + +Multiple components create `/tmp/tytus/` with `create_dir_all` (default permissions). An attacker who pre-creates it owns the directory. + +**Fix:** Verify directory ownership after creation. Or use `$XDG_RUNTIME_DIR` (Linux) / `$TMPDIR` (macOS, per-user: `/var/folders/.../T/`). + +### M5. Daemon Socket Transmits Credentials + +**File:** `daemon.rs:264-297` + +Status response includes `stable_user_key` over Unix socket. Socket has `0o600` permissions, but compromised same-user process can extract credentials. + +**Fix:** Return truncated key by default. Full key only on explicit `auth` subcommand. + +### M6. `tytus env --json` Still Dumps Full PodEntry + +**File:** `cli/src/main.rs:1470` + +`tytus env --json` serializes the entire `PodEntry` struct including `droplet_id`, `droplet_ip`, internal IPs, and both key types. + +**Fix:** Filter output to only stable values. Use `--raw` flag for debug data. + +### M7. MCP `tytus_chat` Allows Arbitrary Prompts + +**File:** `mcp/src/tools.rs:163-228` + +AI agents can send arbitrary prompts through the user's pod without user visibility. Prompt injection vector. + +**Fix:** Rate limiter, token budget, or require explicit user consent per call. + +### M8. MCP `tytus_revoke` Has No Confirmation Gate + +**File:** `mcp/src/tools.rs:230-259` + +The tool description says "confirm with user" but there's no enforcement. Auto-approving MCP clients can revoke pods silently. + +**Fix:** Two-phase revoke with confirmation token. + +### M9. Tray Launcher Write-Then-Chmod Race + +**File:** `tray/src/launcher.rs:140-155` + +Script written with default umask, then `chmod 0o700`. Brief window where file is world-readable. + +**Fix:** Use `O_CREAT|O_EXCL` with mode `0o700` from creation, or use `$TMPDIR`. + +### M10. Separate reqwest Clients Skip Shared TLS Config + +**File:** `cli/src/main.rs:2058-2060, 2165-2168` + +`test_chat_completion()` and `cmd_chat()` create standalone `reqwest::Client`s that don't use the shared HttpClient config. + +**Fix:** Use the shared `HttpClient` for all requests. + +### M11. `SUDO_USER`/`TYTUS_REAL_HOME` Path Not Validated + +**File:** `cli/src/state.rs:44-58` + +`TYTUS_REAL_HOME` is user-controllable and used to construct the state file path. Could redirect state reads to attacker-controlled location. + +**Fix:** Validate: reject if contains `..`, is not an absolute path, or doesn't exist. + +### M12. autostart.log Has No Permission Restriction + +**File:** `cli/src/main.rs:3278, 3330` + +Log file created with default umask (typically `0o644`).

+ + + + From f95685e11e2cbcddf9cd8330e87288962741c97e Mon Sep 17 00:00:00 2001 From: rschumann Date: Sun, 12 Apr 2026 23:42:07 +0200 Subject: [PATCH 15/16] =?UTF-8?q?security:=20E2-E5=20+=20H1=20pentest=20bl?= =?UTF-8?q?ockers=20=E2=80=94=20launch-ready?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Closes every exploited finding from docs/PENTEST-RESULTS-2026-04-12.md except the infra-team items (SSH on droplet, /metrics auth). E2/H2 refresh_token no longer in state.json E3/H5 MCP tytus_env returns stable values by default E4 daemon socket status drops ai_endpoint E5 /tmp/tytus/ is 0700 and files inside are 0600 H1 hardcoded Api-Key formally documented as public client ID # E2/H2 — refresh_token out of state.json `cli/src/state.rs` and `mcp/src/state.rs` now mark refresh_token as `#[serde(default, skip_serializing)]`. Load() reads it from the OS keychain on every call, so the rest of the CLI continues to work unchanged. Legacy state.json files that still contain a refresh_token are migrated eagerly in load(): the value is copied into the keychain, then save_critical() rewrites the file immediately without the field. This closes the window where a failed downstream call would leave plaintext tokens on disk. CRITICAL FIX: `keyring = "3"` ships with NO backends by default — the default bundle is a stub that silently accepts writes and never persists. Enabled features: apple-native, linux-native-sync-persistent, sync-secret-service, windows-native. Before this fix, every previous release that relied on "store in keychain" was actually a no-op. Verified end-to-end: legacy state.json with RT is now migrated into the real macOS login keychain, and subsequent reads load it back. # E3/H5 — MCP stable-by-default mcp/src/tools.rs: tytus_env now returns stable_ai_endpoint + stable_user_key by default. Added `raw` boolean parameter for debug mode (legacy per-pod values). tytus_status no longer leaks ai_endpoint or agent_endpoint. tytus_models and tytus_chat prefer stable values and fall back to per-pod for robustness. mcp/src/main.rs schema updated. # E4 — daemon status redaction cli/src/daemon.rs: removed ai_endpoint from the `status` socket response. Now emits only pod_id, agent_type, tunnel_iface, stable_ai_endpoint, stable_user_key. The CLI's print_*_status() already redacts the same way; the daemon must not leak more. # E5 — /tmp/tytus/ permissions Added `secure_tytus_tmp_dir()` + `secure_chmod_600()` helpers in main.rs and wired every /tmp/tytus/ create/write site: tunnel-up (runs as root), daemon socket + pidfile, autostart.log, tray launcher script, connect's pid+iface files. Directory is 0700, every file inside is 0600. The live machine's existing files were also repermissioned. # H1 — hardcoded Api-Key decision Consulted opencode (MiniMax) + gemini CLI. Weight of evidence: this is a public client identifier, not a secret. Every endpoint that uses it also requires user credentials. Documented as PUBLIC_CLIENT_API_KEY in auth/src/login.rs and auth/src/sentinel.rs with a long comment explaining the threat model. New docs/SECURITY.md captures the full security model including why this is shipped intentionally (same pattern as Firebase API keys, Auth0 client_id, Stripe publishable keys). Not rotatable without breaking every installed binary — if Rails ever adds an endpoint that trusts Api-Key alone, this ceases to be safe and must be caught in Rails review, not CLI review. # Testing - cargo check --workspace: clean - cargo clippy --workspace: clean (one dead_code warning fixed) - cargo test --workspace: 24 tests passed - End-to-end migration test: legacy state.json → keychain +

Enforced via + `secure_tytus_tmp_dir()` + `secure_chmod_600()` helpers called at every + write site (CLI, tray, daemon, tunnel helper). + +4. **WireGuard private keys never touch disk**. The tunnel config is parsed + into an in-memory `TunnelConfig` struct and handed to boringtun directly. + `WireGuardConfig` and `WannolotPassResponse` implement `Zeroize`. + +5. **Sudoers is tightly scoped**. The entry grants exactly two commands: + ``` + /Users/USER/bin/tytus tunnel-up /tmp/tytus/tunnel-*.json + /Users/USER/bin/tytus tunnel-down * + ``` + The `tunnel-down` helper validates the target PID against + `/tmp/tytus/tunnel-*.pid` files before signalling, so it cannot be used as + an arbitrary `kill` primitive.

The key is metadata, not a gatekeeper. + +**Invariant this depends on**: the Rails API must never add an endpoint that +treats `Api-Key` as a standalone credential. If it does, this value becomes +a leaked secret, not a public client ID.
