The linear replay resurrected the July spawn path: mode folded inline
and both confinement and the default cwd fenced to the deployment
workspaceRoot. Master (and the pre-rebase merge result) resolve the
policy once per spawn — resolve({ session }) — so session.header.cwd
is both the workspace-write boundary and the default shell cwd, as the
README already states. Restores the single resolve, threads the policy
through spawnArgv and the cwd fallback, re-expresses master's
session-root test on the terminal spec, and pins the recorded confine
policy in the explicit-cwd test.
Also from the same review round: the Python SDK exe build stages
pty.node from subprocess-local (node-pty's home since the relocation),
and fs-local's README counts the seam's eleven primitives.
Remove the one-consumer bounded-read primitive and shared terminal lifecycle controller, make terminal cleanup one awaited provider operation, and reuse one Code Runtime contract suite. Keep only reproduced cancellation and policy fixes; defer unproven replacement, prompt-attribution, and streaming-frame concerns to scoped markers.
