# Pi 工具桥 v1（moduleId: integ-pi-bridge, 可重生 ✅）
|
||
# 《Pi-Agent兜底能力详细方案》§4.3-4.5 + P1-DESIGN §2.2：
|
||
# - 围墙内工具白名单注册表：P1 阶段只暴露只读工具（fs_read / aps_query 快照 /
|
||
# report_emit 产物出口），写类工具一律不登记——不登记即不可见，这是墙的一部分；
|
||
# - callId 凭证：每次工具调用签发 callId 落 calls.jsonl（入参只落 sha256 摘要，
|
||
# 不落明文）；Pi 报告中引用的 [callId: ...] 必须真实存在，否则判伪造成果；
|
||
# - fs_read 限 run 目录（resolve + is_relative_to，防 ../ 与绝对路径逃逸）。
|
||
# 吸收 poc/pi-fallback/tool_bridge.py 设计，产品级重写，不 import poc。
