**Move structured coding-agent history between tools without collapsing it into a prose summary.**

**Rename note — September 28, 2026:** This project was renamed from **Agent Session Bridge** to **Trajectory Fidelity Bridge** after discovering an older, unrelated public project already using the former name. The projects are unaffiliated. The `agent-session` CLI, `extra.agent_session_bridge` extension namespace, and older PyPI distribution remain available as compatibility identifiers.

Trajectory Fidelity Bridge is an MIT-licensed reference implementation for converting supported coding-agent transcripts into the [Agent Trajectory Interchange Format (ATIF)](https://github.com/harbor-framework/harbor/blob/main/rfcs/0001-trajectory-format.md). It is not a competing interchange standard.

**Current status:** Claude Code JSONL normalization to ATIF v1.7, heuristic secret redaction, TFB fidelity reporting, and an Antigravity derived-log mapping are implemented. Native Antigravity session rehydration is not supported becau
