AgentFlight v1.2.0 — Pre-Flight Cost Circuit Breaker, 0.08 μs Replay & OpenAny Integration

AgentFlight v1.2.0 introduces the official commercial integration with OpenAny, accompanied by production-grade revenue attribution, thread-safe concurrent budget reservations, streaming SSE support, and remote MCP tool auditing.

🌟 Key Highlights

1. Verified Partner Attribution Infrastructure:
   • Outbound requests to OpenAny now transmit the verified partner header:

     X-OpenAny-Partner-Id: agentflight

   • Domain boundary isolation strictly prevents header and credential leakage to third-party domains.
2. Thread-Safe Budget Reservations (TrajectoryCircuitBreaker):
   • Added guard.reserve_budget(amount_usd) with BudgetReservation context manager.
   • Prevents race conditions in multi-threaded and concurrent agent runs from bypassing spending caps before completion.
   • Pre-execution budget evaluations halt unaffordable requests before network dispatch ($0.00 spent).
3. Streaming Chat Completions (stream_chat):
   • Added generator support for real-time Server-Sent Events (SSE) streaming.
   • Live chunk delivery with post-stream token reconciliation and span recording.
4. Remote MCP Tool-Smell Auditing:
   • Query and lint remote OpenAny MCP servers (https://mcp.openany.si/mcp).
   • Audit schemas against rules TS001–TS010 to trim prompt bloat by up to 78%.
5. Sub-Microsecond Deterministic Replay Benchmark:
   • Benchmarked at 0.08 μs per span (>11,000,000 spans/sec) across 25,000 span trials.
   • 100% offline with zero external network calls.
6. Refined Secret Redaction:
   • Intelligent masking protects sensitive keys and bearer tokens while preserving numerical metric tokens (prompt_tokens, completion_tokens, total_tokens).
