v1.61.0 — Agent Stamina Profiler, Competency Map, Collaboration Analyzer & 39 Performance Optimizations

Highlights

Agent Stamina Profiler — Autonomous intra-session degradation detection that identifies when agents lose coherence, slow down, or produce lower quality output over the course of long sessions.

Agent Competency Map — Autonomous skill profiling that builds a capability matrix across agents, enabling intelligent task routing based on demonstrated strengths.

Agent Collaboration Analyzer — Multi-agent teamwork analysis measuring communication efficiency, contribution balance, and coordination patterns across collaborative sessions.

Schema Migration System — Lightweight, versioned database migrations with auto-detection of pending upgrades and rollback support.

Performance (39 optimizations)

• O(1) closed-form linear regression in memory leak detector
• O(log n) window filtering via bisect timestamp index in quota
• Single-pass metric extraction across capacity planner, drift, narrative, latency, and anomaly modules
• Pre-computed LCS keys + fast-path identical sequences in session_diff
• Cache model aggregates and eliminate redundant sorts in forecast
• Amortized entropy syscall with pre-allocated random ID pool
• Eliminated spread-copy in parseEventRow and reduced export allocations
• Fixed LRU cache pollution in session search
• Mann-Whitney U via sort-based rank-sum (O(n log n))
• Single-pass GroupStats initialization (7 passes to 1)
• MTBF computed in SQL with wrapped transactions
• Flamegraph event-to-span placement O(EDlogS) + cached sentence tokenization
• Static assets served before API middleware stack + covering index for analytics

Security (13 fixes)

• Redact sensitive kwargs in decorator tracking (CWE-532)
• ReDoS timeout guards for user-controlled regex
• HTML-escape user-controlled data in dashboard template (CWE-79)
• Sanitize agent_name inputs, cap window_hours in SLA
• Add usedforsecurity=False to md5 calls
• Restrict file permissions on config containing API key
• Harden correlation-scheduler against DoS and resource exhaustion
• Fix SQLite variable overflow and validate agent names in profiler
• Cap unbounded query parameters for SQLite safety
• Validate input types in PUT handlers
• URL-encode CLI query parameters to prevent CWE-74 injection
• Harden severity classification and annotation input validation
• Input validation on anomaly endpoints

Bug Fixes (16)

• Report truncated fields in ingest response
• Update MODEL_PRICING with current models and add runtime override API
• Fix ReferenceError in forecast trend detection
• Cap event buffer and alert history to prevent memory leak

• Align SQL column names with actual sessions/events schema
• Patch 3 npm audit vulnerabilities (path-to-regexp ReDoS, brace-expansion, picomatch)
• Validate session status against allowed values
• Fix undefined name bug in cli_bottleneck

Refactoring (25 changes)
