GateWeave: Adaptive memory admission control with belief versioning

[Copilot]

TIMPs stores every memory indiscriminately, leading to storage bloat, degraded retrieval precision, and no mechanism for tracking evolving user beliefs. Contradictions are caught post-hoc with no versioning, so outdated positions silently propagate into downstream tools.

GateWeave adds write-time admission gating and belief versioning to the memory pipeline.

Core service (core/gateWeave.ts)

• 5-dimensional admission scoring: utility (embedding overlap with recent context), confidence (importance + concreteness), novelty (cosine distance to existing), recency (temporal decay), tool-relevance (keyword match against TIMPs tools)
• 3-tier gating: admit (≥0.45 → full PG+Qdrant store), summarize (≥0.25 → compressed summary), discard (<0.25 → skip)
• Belief versioning: position-like statements create versioned nodes with parent chain linking and status tracking (active/superseded/retracted)
• Proactive propagation: high-impact belief changes flag burnout baselines and relationship health for recomputation

Write-time integration (memory/memoryIndex.ts)

const admission = await gateWeave.evaluateMemory(userId, projectId, content, ...);
if (admission.decision === 'discard') return null;
if (admission.decision === 'summarize') {
  await gateWeave.summarizeAndLink(userId, projectId, content, tags);
  return null;
}
// admit path: store normally, then propagate if belief was versioned

Falls back to unconditional storage if GateWeave fails.

Schema (db/gateWeaveDb.ts)

• belief_versions — versioned belief chains with parent links, confidence, contradiction refs
• gateweave_decisions — admission audit log with score breakdowns
• gateweave_summaries — compressed rollups for medium-value gated content

Tool 18 (tools/gateWeaveTool.ts)

Operations: stats, list_beliefs, belief_history, tune_weights — exposes admission metrics and belief chains to the agent and user.

Integration touchpoints

• toolRouter.ts — keyword patterns + LLM routing for gateweave
• agent.ts — system prompt updated (17→18 tools)
