Built on strict operational invariants

Autonomous coding and operations agents fail when state drifts silently. DT-Linker enforces deterministic verification before a single packet or process leaves the host.

Append-only execution ledger

Every round, tool call, and verification gate is committed as an immutable snapshot. Completed nodes and frozen topological edges cannot be retroactively rewritten, eliminating split-brain state across long-horizon agent workflows.

ledger.commit({ round: 14, node: "verifier_gate", carryover: "summary_only", state: "SEALED" })

Fail-closed pre-flight admission

Seccomp sandbox availability, token consistency, and egress route integrity are verified before process spawn. Any mismatch aborts execution immediately rather than degrading silently.

exit_code: 78 (ADMISSION_REFUSED)

Role-scoped memory isolation

Builder nodes retain structured conclusion carryover for session continuity, while independent judge and verification nodes run in stateless clean rooms to prevent confirmation bias.

judge_node: { carryover: false }

Decoupled async lease multiplexing

Unbounded model execution never runs inside lock-holding transactions. DT-Linker dispatches heterogeneous CLI and WebSocket workers with independent heartbeats and automatic token-drift recycling.

Runtime specifications

Designed for engineering organizations running high-autonomy agent fleets across local macOS/Linux workstations and isolated cloud sandboxes.

01 / Admission & Identity
Token-pinned adapter lifecycle
Runtime adapters compare active profile tokens prior to short-circuiting and recycle stale daemons automatically.
Hardware enclave virtualization
Per-workspace hardware UUID isolation prevents cross-tenant telemetry correlation.
02 / DAG Orchestration
Deterministic self-repair loops
Hard validation failures serialize into structured facts for bounded self-correction with zero-progress detection.
Explicit truncation contracts
Oversized context blocks are marked with explicit raw references rather than silently truncated.
03 / Transport & Security
Dual-layer TLS 1.3 egress
All outbound agent traffic traverses pinned HTTP CONNECT over TLS tunnels with zero non-proxied UDP leakage.
Seccomp script sandboxing
Untrusted automation nodes execute inside dedicated worker queues with kernel-level syscall filtering.
