Capture
Save supported browser organization, VS Code workspace/editor context, selected folder/terminal context and service expectations into a durable project checkpoint.
WINDOWS PRIVATE BETA · LOCAL-FIRST
Put your workspace to sleep.
Wake up ready.
ContextSleep puts a workspace to sleep by saving the context that matters, safely closing supported parts, and reconstructing them later with verification instead of guessing what came back.
✓ Review before close
✓ Verified restore
✓ Local workspace data
Unsigned private beta for Windows 10/11. No installer or auto-updater yet.

THE LOOP
Not “reopen some apps.”
Reconstruct a workspace with evidence.
ContextSleep separates capture, destructive action and restore into explicit steps. Unsupported or ambiguous targets stay open instead of being guessed.
Review
See what can actually be reconstructed. Dirty work, unsupported states and ambiguous native ownership block automatic close.
Sleep
Only reviewed, freshly rechecked targets are closed. A failed or unverified close stops later destructive actions.
Resume
Cold-launch the saved Chrome profile and VS Code workspace, restart approved services, then verify each selected capability before reporting ready.
VALIDATED, NOT HAND-WAVED
The packaged lifecycle has passed end to end.
In the current validated flow, one checkpoint closed VS Code, Chrome and a reviewed service, ContextSleep itself restarted, then the saved workspace was cold-restored and overall readiness returned to ready.

GPT-6 ASTRA
BUILT WITH GPT-6 ASTRA
Astra helped with the parts where guessing would be dangerous.
Astra worked alongside the project on Windows process/window ownership, durable native-close verification, cold-start recovery, service lifecycle design, safety boundaries and end-to-end validation.
Example: shared-process VS Code windows
Two VS Code workbenches can share one GUI process. Astra investigated the native HWND/process topology and found no trustworthy supported primitive that mapped the exact integration instance to the exact workbench window. ContextSleep therefore blocks automatic close in that ambiguous case rather than relying on titles, focus state or timing guesses.
PRIVATE BETA SCOPE
Useful now. Deliberately honest about the edges.
VS Code
Saved local workspace/editor context, reviewed native close when unambiguous, and cold restore back to the same integration identity.
Chrome
Profile-bound capture and cold restore with tab/group verification. Quick Sleep can discard eligible background tabs separately.
Dev services
Explicitly reviewed direct Node/Python service definitions with verified ownership, graceful stop and checkpoint-driven restart.
Explorer + terminals
Folders and verified instrumented prompt working directories are restored as context. Arbitrary terminal history, panes and commands are never replayed.
CURRENT LIMITS
Fail closed beats pretending.
- Windows only for this beta.
- Actual Windows reboot recovery has not yet been validated.
- Multiple VS Code workbench windows sharing one GUI process block automatic close.
- Explorer and arbitrary Windows Terminal windows are Context Restore, not automatic sleep/close.
- The build is unsigned and uses a portable setup helper rather than a polished installer.
