Omar SobhandClaude Fable 5 84c51168be P6: strict seccomp allowlist + K8s sandbox driver proven on kind
- images/seccomp/agent-profile.json is now a TRUE ALLOWLIST: Docker's
  default profile (vendored from moby v27.5.1, defaultAction ERRNO) with
  18 syscalls an agent never needs stripped from the allow groups
  (unshare, ptrace, bpf, mount family, setns, module loading,
  perf_event_open, process_vm_*, reboot, quotactl, ...); arch map trimmed
  to x86_64 + aarch64. All 6 Docker kernel assertions still green.
- K8sDriver (tc-sandbox feature 'k8s', kube-rs): one hardened pod per
  sandbox — runAsUser 10001, cap-drop ALL, no-new-privs via
  allowPrivilegeEscalation=false, RuntimeDefault seccomp, read-only
  rootfs with emptyDir /tmp + /home/agent, resource limits, no service
  account token — in a PSS-restricted namespace carrying a default-deny
  NetworkPolicy (applied server-side apply, idempotent). Exec via the API
  server attach channel with exit codes parsed from v1.Status.
- Live suite (feature 'k8s-tests') against a REAL kind cluster: uid /
  CapEff==0 / NoNewPrivs / rootfs probes from inside pods, PSS label +
  deny-all policy asserted via the API, lifecycle. Honest limits in the
  rustdoc: Localhost seccomp profile and CNI-enforced egress are
  per-cluster provisioning (kindnet does not enforce NetworkPolicy).
- rustls 0.23 process provider pinned to ring at driver connect.
- CI: dedicated sandbox-k8s job (helm/kind-action) running the suite.

149 Rust tests + 3 live kind tests; clippy clean including the k8s feature.

Omar SobhandClaude Fable 5 ea5162ac65 P2 complete: Docker sandbox with kernel assertions + secret broker
tc-sandbox:
- SandboxSpec/SandboxDriver + DockerDriver (bollard): uid 10001, cap-drop
  ALL, no-new-privileges, embedded seccomp deny profile (unshare/ptrace/
  bpf/keyctl/mount/...), read-only rootfs with tmpfs /tmp + /home/agent,
  network=none, mem/cpu/pids limits
- agent-base image: non-root, all setuid binaries stripped
- 6 kernel-level assertion tests probing from INSIDE real containers:
  uid + CapEff==0, rootfs read-only, seccomp EPERM on unshare, zero
  traffic-carrying interfaces + failed egress connect, no setuid +
  NoNewPrivs=1, lifecycle

tc-secrets:
- ChaCha20-Poly1305 envelope encryption under a FileKey (generated 0600,
  AEAD tamper detection tested); secrets table ciphertext-at-rest
- teamclaw-broker daemon: length-prefixed JSON over a unix socket; no
  protocol operation ever returns plaintext; InvokeHttp independently
  consumes the single-use execution grant against Postgres BEFORE touching
  any credential, then performs the call itself with the secret injected
- Tests over the real socket + real Postgres + a real local HTTP receiver:
  encrypted at rest, pending approval refused, approved call carries the
  bearer token exactly once, grant replay refused, non-http URLs rejected

116 Rust + 61 frontend tests + 14 E2E journeys green.
