PR 29757 real Linux dev verification
main: 61c3794c32; PR: f3ae461c3f1cd1ed482d8b78460715ec99b8faa3
One server at a time, vp i then background vp run dev, isolated .t3 state.
Real web app driven by repo Playwright and /usr/bin/google-chrome.
Project /home/user/t3code added via Add project > Local folder.
Official Claude CLI installed frontend-design, plugin-dev and claude-md-management
at project scope from /home/user/t3code/apps/web. No synthetic registry.
Authenticated web WebSocket RPC used the same server.refreshProviders method as
client workspace refresh, instanceId claudeAgent, cwd /home/user/t3code,
fresh true, workspaceSnapshotsOnDemand true.
strace observed actual server FileSystem access calls, correlated to the
server discoverPluginSkillRoots span timestamps.

MAIN: one discovery, repeated nested project .git probe count = 3.
PR: one discovery, same repeated nested project .git probe count = 1.
PR: findRepositoryRoot and findPluginRepositoryRoot helper spans = 0.
Both returned frontend-design and all seven plugin-dev skills.
No elapsed-time speedup claim: tracing instrumentation adds overhead.

Nearby behavior on PR:
claude plugin disable plugin-dev --scope user -> next fresh workspace refresh:
all plugin-dev skills absent, frontend-design still present.
claude plugin enable plugin-dev --scope user -> next fresh workspace refresh:
all seven plugin-dev skills restored.
