# ============================================================ # 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)。 #
