# Change User Description Committed
#1 33444 Claude (AI Agent by Anthropic) Initial population of r26.1.0.BETA from main.
//p4-sdp/main/Server/test/snippets/set_DO_PARALLEL_CHECKPOINTS_threads.snippet
#1 33433 Claude (AI Agent by Anthropic) Copy Up from //p4-sdp/dev into //p4-sdp/main.

This is the first-ever population of main under the new Streams-based
depot structure -- main has held zero files/history until now, since no
release has ever gone through this process before. 463 files, covering
the entire 2026.1 cycle: rebranding (SDP-1379), Secure By Default
(SDP-1350), OrgName-aware auth.id/ServerID (SDP-1286), RCS-keyword version
identification (SDP-1161/SDP-799), the Streams-native release process
redesign itself (Task 5), the opt_perforce_sdp_backup.sh false-error fix,
the P4D 2026.1 test-suite targeting, refreshed P4*.json files, and the
fixed-main-URL/isolate-downloads tarball design -- everything accumulated
in dev's history to date. Isolated paths (ai_dev_support/, Version,
doc/*.html, doc/*.pdf, doc/gen/*.man.txt, doc/gen/sdp_install.cfg,
Unsupported/doc/*.html, Unsupported/doc/*.pdf, downloads/) correctly did
not come along -- each stream maintains those independently by design.

Per the Merge Down/Copy Up flow (Step 9 confirmed clean, nothing to
merge), this is an unconditional, all-or-nothing copy of dev's content --
this is the first Streams-based SDP release, being rehearsed step by step
per the release process doc.

#1 29434 C. Thomas Tyler Tweaked code deriving Threads values from user-defined DO_PARALLEL_CHECKPOINT.

Added a stand-alone test script for tweaking that snippet of code.
