A weekly 涉诈APP (fraud-suspected app) disposition report for Nov 5 covers 20 apps (12 with overseas servers); alongside genuine scam-lottery domain clusters (玖富彩票) it lists mainstream, non-fraud consumer apps -- Shopee (major Southeast Asian e-commerce platform) and Trust Wallet (widely-used cryptocurrency wallet) -- each with extracted domains/IPs/API paths and a disposition of 系统处置情况：新增拦截处置 (newly added to blocking), showing the anti-fraud program blocks broadly-used legitimate commercial/financial apps under the same infrastructure and process used against actual scam operations.

Internal MAAT engineering specification (v3.1.20, MESA Lab, revision history spanning 2014-2021) documents the config schema underlying sapp's rule-matching engine: per-rule action types (0=block/阻断, 1=monitor/监测, 2=whitelist/白名单), string/regex/IP/numeric/digest match types, and a geographic+ISP "tag" targeting system that lets the identical rule set be selectively activated per city district and carrier (e.g. Beijing/Chaoyang + China Telecom vs. Shanghai/Pudong), enabling narrowly-scoped rule rollout/testing before wider deployment.

Session-log exports from a Beijing test/demo TSG device ("XXG-TSG-BJ") show live "Deny" enforcement actions (security_rule_list "Deny_VPNHero", "deny_TowerVPN") against traffic the app-ID engine classified with nested app chains "VPNHero" and "OPENVPN.TowerVPN.Psiphon Provider.Psiphon-Server" -- i.e. TowerVPN is specifically tagged internally as riding on Psiphon infrastructure, and both it and VPNHero are actively blocked, not just logged, on this device.

An internal TSG operations/troubleshooting manual lays out TSG's full traffic pipeline (NIC -> mrzcpd/marsio capture driver -> sapp DPI engine -> firewall/proxy(KNI->TFE)/active-defense/WAN-NAT policy branches) and shows engineers using maat_redis_tool to pull the live Redis-synced blocking policy tables (TSG_SECURITY_COMPILE, TSG_OBJ_IP_ADDR, TSG_OBJ_APP_ID) and filter them by numeric policy/object ID to debug why a block rule isn't firing.

The internal 'MAAT网络流处理配置统一描述框架' engineering manual (v3.1.20, author 郑超, 2021) documents MAAT's Redis-synced rule-compilation framework and its RuleScan/Hyperscan-based pattern-matching engine (libmaatframe.so / librulescan), and records that RuleScan's fast-scan feature caused a production outage on 2019-03-19 and has been disabled ever since.

A MESA Lab monthly report states that adjustments to a VPN-detection module accumulated over 10,000 Psiphon3 server IPs and delayed a Psiphon3 client's ability to get online by at least 3 minutes in the researchers' test environment, an earlier-stage data point consistent with the much larger-scale (~70-73K IP) 'vpn-thwarting'/CyberNarrator Psiphon-harvesting pipeline documented elsewhere in this corpus.

An internal design note for a 'Shadowsocks traffic parsing/restoration module' describes decrypting captured Shadowsocks payloads back to the original HTTP request/response, given a known pre-shared key (AES-256-CFB, MD5-derived key, IV embedded in the stream).
