Private-by-default memory and context orchestration for AI agents.

ContextLattice provides a single memory contract for agentic systems:

• Unified write/read contract for memory and context.
• Durable fanout across retrieval/storage lanes.
• Staged retrieval (fast now, deep continuation when needed).
• Agent sessions that turn prior work, graph touches, skills, checkpoints, and handoffs into prompt-ready packages and exportable run cards.
• Go/Rust runtime ownership for the active application path.
• Legacy Python runtime archived under archive/services/orchestrator_legacy_python for tooling/test compatibility only.
• Local-first deployment with optional hosted surfaces.

v3.4.2 is the public agent runtime contract baseline: universal adapter lifecycle, native agent sessions, objective runtime state, scoped recall, checkpoints, handoffs, completion flow, runtime telemetry, one-command runtime proof, storage-governance hardening, and local session-store diagnostics behind one local contract.

v4 remains the private tuning lane for experiments that still need benchmark, recall, and soak gates before public promotion.

• Ingress: gateway-go.
• Core memory + retrieval lanes: Go + Rust services.
• Degradation policy: fail-open retrieval with continuation lifecycle.
• Tooling compatibility: MCP + HTTP clients.
• Single-container lite builds (Dockerfile.hf-lite) also run gateway-go (no Python runtime dependency).
• Public single-container lite vector default: topic_rollups only.
• Public local lite core default: topic_rollups + qdrant; pgvector and memory-bank spike adapters are not started by default.
• Public local lite advanced: opt-in adapter lab via gmake mem-up-lite-advanced.
• Full/operator stacks: Qdrant remains the primary vector-native lane; pgvector stays supported for SQL-co-located vector workloads.

gmake quickstart

gmake quickstart prompts for runtime profile and then launches the selected stack.

curl -fsS http://127.0.0.1:8075/health | jq
scripts/agent/agent-runtime-proof-pack --pretty
scripts/agent/agent-adoption-proof-matrix --skip-provider-smoke --progress --pretty

Expected:

• /health returns {"ok": true, ...}
• agent-runtime-proof-pack completes bootstrap, scoped recall, checkpoint, handoff, completion, status, prompt context package, and runtime telemetry phases.
• agent-adoption-proof-matrix verifies configured agent profiles and reports the skills, context, session, graph, and handoff evidence shaping each run, with trace commands for run-card export.

Task inference defaults to ORCH_INFER_PROVIDER=auto. gateway-go detects the host profile and probes local backends before selecting a route.

• Apple Silicon default priority: mlx,vllm-metal,ane_sidecar,llama-cpp,ollama.
• CUDA/ROCm default priority: sglang,vllm,openai-compatible,llama-cpp,lmstudio,ollama.
• Generic CPU default priority: openai-compatible,llama-cpp,lmstudio,ollama.
• Supported provider ids include sglang, vllm, vllm-metal, mlx, mtplx (alias for MLX), openai-compatible, lmstudio, llama-cpp, tgi, tensorrt-llm, ane_sidecar, and ollama.
• /v1/inference/runtime-policy returns live provider health plus resource-aware model guidance. If host memory/VRAM is not identifiable, it falls back to generic local advice: start with Q4/IQ4 7B-9B models, benchmark, then scale up.
• Large Qwen3.6 Dream Mode models are opt-in only; ContextLattice does not bundle or pull them by default. The default GGUF recommendation is mudler/Qwen3.6-35B-A3B-Claude-4.7-Opus-Reasoning-Distilled-APEX-MTP-GGUF for llama.cpp-compatible advanced users. Abliterated variants are private-eval only behind CONTEXTLATTICE_DREAM_ALLOW_PRIVATE_EVAL_MODELS=true (GO_DREAM_ALLOW_UNCENSORED_MODELS=true remains a legacy alias).
• Inference runtimes must emit final assistant content through their API. Reasoning-only responses fail with repair instructions instead of being accepted. For MLX Qwen thinking templates, use scripts/inference_mlx_server.sh --model /path/to/mlx/model --template-profile qwen-final-content, then verify with scripts/inference_template_conformance.sh --provider mlx --model /path/to/mlx/model.
• Dream Mode reflects on generated hypotheses by default and performs one bounded deepening pass when the best output misses the sigma target (GO_DREAM_REFLECT_ENABLED=true, GO_DREAM_DEEPEN_ON_WEAK_OUTPUT=true, GO_DREAM_REFLECTION_MIN_SCORE=0.74).
• Ollama remains a compatibility fallback, not the preferred always-on embedding path.
• Local helpers enforce one active LLM backend by default (CONTEXTLATTICE_SINGLE_ACTIVE_INFER_BACKEND=true).

Inspect live routing and benchmark configured backends:

scripts/inference_runtime_policy.sh
scripts/benchmark_inference_backends.sh
scripts/inference_template_conformance.sh --provider mlx --model /path/to/mlx/model

Embedding defaults to the Rust fastembed-rs sidecar. Ollama stays available as an explicit compatibility fallback, not the preferred embedding path.

• contextlattice_agent_adapter is the first-class lifecycle helper for bootstrap, context-pack, checkpoint, handoff, event, and completion flows.
• contextlattice_adopt is the zero-friction front door for local readiness, install repair, lifecycle proof, no-secrets agent packs, and new agent profile templates.
• contextlattice_agent_start runs the lightweight startup guard for agents.
• contextlattice_agent_trace renders the bounded run-shaping trail as a terminal tree, JSON, or Markdown run card.
• contextlattice_pack compiles a bounded prompt-ready packet with ranked evidence, files to inspect, risks, checks, source coverage, and a reference_prompt.
• contextlattice_checkpoint writes a checkpoint and verifies readback.
• contextlattice_source_backfill imports bounded files, JSONL, JSON, CSV, SQLite, DuckDB/Parquet, or Postgres data through the same memory write contract.
• Hook pack details: docs/agent-hooks.md.

ContextLattice tracks live agent work as first-class sessions, independent of the runner or model provider.

• Start/list/read sessions through GET|POST /v1/agents/sessions and GET /v1/agents/sessions/{session_id}.
• Emit normalized events through POST /v1/agents/sessions/event or POST /v1/agents/sessions/{session_id}/events.
• Inspect a bounded run trace through GET /v1/agents/sessions/{session_id}/trace; the trace reports context, skills that may be helpful, source coverage, graph touches, handoffs, checkpoints, and timeline events without raw provider payloads.
• Read live runtime telemetry from GET /telemetry/agents/runtime.
• Compile task context through POST /memory/context-pack, POST /tools/context_pack, or global contextlattice_pack; responses include context_compiler, ranked evidence, prompt sections, and a bounded reference_prompt.
• Preflight, context-pack, and Dream Mode return objective_runtime_state.v1 with objective_state, action_executed, evidence, objective_delta, risk_or_blocker, and next_action.
• Use scripts/agent/contextlattice-agent-adapter or global contextlattice_agent_adapter as the first-class product path for agent bootstrap, context-pack, checkpoint, handoff, event, and completion flows.
• Use scripts/agent/contextlattice-adopt or global contextlattice_adopt before handing ContextLattice to a new agent/account; it wraps gateway health, helper install state, shell PATH, storage posture, session store, profile coverage, and runtime-doctor checks into one bounded report.
• Run scripts/agent/agent-runtime-proof-pack --pretty or global contextlattice_agent_runtime_proof --pretty for a one-command live proof that bootstrap, scoped recall, checkpoint, handoff, completion, status, and runtime telemetry are wired end to end.
• Use scripts/agent/contextlattice-session for CLI start/event/complete/fail/status/runtime/trace flows.
• Use scripts/agent/agent-run-trace --session-id <id> --tree or global contextlattice_agent_trace --session-id <id> --tree to see the terminal trace, then --markdown to export the run card.
• Use scripts/agent/contextlattice-session sweep-stale-audits --all-projects --pretty for dry-run-first cleanup of stale objective-runtime audit/preflight sessions; add --confirm only after reviewing matches.
• scripts/agent/contextlattice-pack, scripts/agent/contextlattice-dream, scripts/agent/writeback, and compaction hooks auto-start or recover a session when CONTEXTLATTICE_SESSION_ID is absent.
• Pass --session-id or CONTEXTLATTICE_SESSION_ID to force a specific session. Set CONTEXTLATTICE_AUTO_SESSION_DISABLED=1 to disable automatic session creation.

Canonical event families include session.started, context_pack.completed, dream.completed, graph.neighbors_returned, graph.edge_touched, decision.made, test.ran, handoff.created, writeback.completed, and session.completed.

Supported adapters: files/directories, JSONL, JSON, CSV, SQLite, DuckDB, Parquet via DuckDB, and Postgres via optional psycopg. Import caps cover records, row bytes, document bytes, total bytes, and structured-list items. Secret-like fields are redacted by default, and graph edge repair is optional and bounded.

ContextLattice exposes active skills as a native Go Skills Index so agents can discover relevant capabilities without loading every SKILL.md into prompt context. In local installs, the active index mounts ${HOME}/.codex/skills read-only by default. Quarantined/vendor skill discovery remains a separate read-only lane and does not auto-load quarantined skills.

• Active index endpoint: GET|POST /v1/skills/index/search
• Active index tool: GET|POST /tools/skills_index_search
• Active index status/reindex endpoint: POST /v1/skills/index/reindex (live native scan; no prompt loading)
• Search endpoint: GET|POST /v1/skills/quarantine/search
• Tool alias: GET|POST /tools/skills_quarantine_search
• Reindex endpoint: POST /v1/skills/quarantine/reindex (off by default; enable explicitly)
