Description
Warm devenv shell on PR #464 is down to roughly 1.16s-1.23s, and traced shell-entry tasks are down to roughly 459ms, but the end-to-end shell still misses the sub-second target.
Context:
- repo-side bootstrap work is now largely cached/skipped via the outer setup fingerprint and faster task status paths
- the remaining floor appears to be outside repo task execution or in the residual
setup:gate/ shell activation path
Follow-up:
- separate repo-local hot-path costs from upstream
devenv shellactivation overhead - determine whether the remaining floor can be reduced further from inside
setup.nixor needs an upstreamdevenvchange

Research direction
Start with the warm devenv shell measurements and the traced shell-entry tasks described in this issue, then inspect setup.nix and the residual setup:gate or shell activation path. Compare repo-local costs with upstream devenv activation overhead. Done means identifying the remaining floor and documenting whether it can be reduced in setup.nix or requires an upstream change.
