v3.4.0 - Agent Runtime Contract + Universal Adapter

ContextLattice v3.4.0 - Agent Runtime Contract + Universal Adapter

This release upgrades ContextLattice from a memory service agents can call into a runtime contract agents can inhabit.

Highlights

• Universal contextlattice_agent_adapter lifecycle: bootstrap, context-pack, checkpoint, handoff, event, and complete.
• Native agent runtime sessions through /v1/agents/sessions and /telemetry/agents/runtime.
• objective_runtime_state.v1 across preflight, context-pack, and Dream Mode.
• Public CLI, llms.txt, Updates, installation, and overview pages now identify v3.4.0 as the public baseline.
• Dry-run-first stale objective-runtime audit cleanup via scripts/agent/contextlattice-session sweep-stale-audits.
• Public CI/path hardening: scripts/contextlattice_client.py now falls back to urllib when httpx is unavailable.

Version Boundary

• v3.4.0 is the stable public agent runtime contract baseline.
• v4 remains the private tuning/experiment lane until benchmark, recall, and soak gates justify promotion.

Verification

• Private PR #443 merged: 92941b4.
• Public PR #257 merged: 0e4dc37.
• Public-paid PR #444 merged: febc959.
• Public agent-context-gate passed after dependency-free audit fallback.
• Public submission preflight passed 100/100.
• Public-paid clean-HOME audit-agent-context passed with hard_failures=[].
• Live universal adapter audit passed for 8 profiles: bootstrap/context-pack/checkpoint/handoff/complete.
• Active sessions after release checks: 3; stale audit sweep dry-run matched 0.
