A log-stream double-write Flink program (galaxy/tsg_olap/log-stream-doublewrite) was purpose-built and repeatedly updated for "P19" -- the internal codename for the Pakistan (WMS-UTR) TSG deployment -- replicating TSG session-record logs to a secondary sink, evidencing dedicated engineering investment in the Pakistan customer's log pipeline distinct from the base product.

An 'ADC Hardware Installation and Configuration Guide' (v21.11) describes a modular chassis (Switch Sled, CPU Sled) matching taxonomy's Pakistan/WMS-UTR 'ADC hardware' reference, confirming ADC is a distinct deployed hardware line -- not just a site nickname -- with its own installation documentation separate from the TSG-X/TSG-7400 line.

A thesis-project assignment for hidden-service (VPN/Proxy/Tor) identification via heterogeneous graph neural networks on flow logs sources its one day of training data from a database explicitly named 'tsg_galaxy_p19' — tying the internal TSG naming convention to the taxonomy's P19/WMS-UTR Pakistan site codename — accessed over an internal 'Information Harbor' (信息港) VPN, with ground-truth hidden-service IP labels supplied by the commercial IP-intelligence service spur.us.

At a Pakistan site (P19/MSH), Geedge identified that TCP RST-injection for a Deny action fails on asymmetric ('unidirectional') flows because the synthetic RST packet lacks GRE callid/routing context only present when both directions transit the same node. Two fixes are in progress: a dedicated third-layer packet-injection route, or a cluster-wide coordination mechanism ('SwarmKV') that syncs which policy a session matched across nodes so each node can independently inject its own side's interference packet.

Geedge Networks' 2023 new-hire onboarding deck gives a corporate timeline: TSG's first international market win (with a codename "Nezha" launching the same month) in September 2018, "网络叙事者" (CyberNarrator) launching November 2020, a "South Asia" country project landing August 2021 (overseas market expansion), and Geedge winning a bid as overall solution provider for an "East Africa" country project in May 2022 — timing and regions consistent with this corpus's existing Pakistan (WMS-UTR/P19) and Ethiopia (E21) site attributions, though the deck itself does not name the countries.

Geedge's internal company timeline dates the launch of 网络叙事者 (CyberNarrator) to November 2020, and states the company won a 'South Asian country' project in May 2021 (consistent with Pakistan/WMS-UTR) and, as overall solution provider, an 'East Africa country' project in May 2022 (consistent with Ethiopia/HDM) -- corroborating the export timeline for those two customers from the company's own materials rather than site-side evidence alone.

At a 'WMS-UTR' project deployment, Huawei DPI equipment operating alongside Geedge TSG at sites abbreviated TWA/PCAP/MSH independently applies a SIP-protocol Deny policy with IP allowlisting -- confirming TSG is deployed in a multi-vendor stack alongside Huawei DPI hardware at the same customer site, not as the sole detection layer.
