Old updaters keep running after the checkout changes. Returning None
from their removed uv helpers enables a pip fallback against the new tree.
Keep the historical imports as inert shims and stop dependency entrypoints
with a relaunch message instead. Do not call PM or write recovery markers
from that mixed-version process.
Self-managed source launches use PM's successful input stamp to decide
when dependencies need a sync. Restart on the managed interpreter before
activating the selected generation. Preserve launcher forms and options,
and do not sync while a live updater owns the installation.
Targeted runtime batch: 225 passed, 8 platform skips. Real PM worker tests
build and publish disposable dependency generations, retain prior state on
failure, and exercise fresh-process relaunch before dependency activation.
The final launch guard test also passes. Full suite and native Windows
execution were not run locally.
Rip out the Termux/Android install lane: constraints-termux.txt,
psutil_android extraction, termux-browser tests, the apt install-method
lane in install.sh, termux api detection, and the TUI termux layout.
Zero added termux lines; 255 removed. System prompt and skill-utils
termux branches drop with the platform they served.
Rebuilt from ethie/pm (f8236a2d91, 7ad9f0c7a5, 8446c871b6, 82fb8e09d1)
onto the pm-store stack. 11 hot files hand-merged; test_code_execution
restored to branch-final (termux path assertions removed).
