AgentFlight v1.1.0 — Trajectory Differential Analyzer & OpenTelemetry/W3C Span Exporter

AgentFlight v1.1.0 Release Notes

New Features

1. Trajectory Differential Analyzer & Regression Detector (src/agentflight/diff.py):
   • Compares a baseline cassette (baseline.jsonl) against a candidate cassette (candidate.jsonl) across model or prompt upgrades.
   • Computes Wagner-Fischer Levenshtein edit distance and Longest Common Subsequence (LCS) over tool call sequences.
   • Detects new tool execution errors, loop/oscillation regressions via TrajectoryCircuitBreaker, token & USD cost deltas (cost_delta_pct, token_delta_pct), latency deltas (latency_delta_pct), and structural output drift.
   • Returns an immutable TrajectoryDiffReport (regression_detected, similarity_score, added_tools, removed_tools, summary_markdown).
2. OpenTelemetry / W3C TraceContext Span Exporter (src/agentflight/otel_export.py):
   • Converts recorded AgentFlight cassette spans into W3C TraceContext / OpenTelemetry JSON spans (trace_id, span_id, parent_span_id, service_name, operation_name, start_time_ms, duration_ms, status_code, attributes) directly ingestible by codesphere-u/stackpulse for critical-path DAG analysis and SLO burn-rate monitoring.
3. CLI & MCP Server Extensions (cli.py, mcp_server.py):
   • CLI: agentflight diff <baseline> <candidate> [--json] and agentflight export-otel <cassette> [--output spans.json].
   • MCP Server (AgentFlightMCPServer): Exposes agentflight_diff_cassettes, agentflight_export_otel, agentflight_lint_tools, and agentflight_verify_cassette.
4. Expanded Test Suite:
   • 90 passing pytest tests across Python 3.10, 3.11, and 3.12 (up from 73 in v1.0.0).
