Why

Upstream pstack 0.15.36 (cursor/plugins#1043, commit c742dd6) rewrote the Orchestrate playbook to be agentic: the coordinator runs the program with its own tools instead of the Bun orch CLI, and the playbook is reorganized into Topology and Supervision rules.

What changed upstream

• Orchestrate shrinks from ~110 lines to ~25: one owner per PR, a fresh worker per independent task with upstream reports pasted in full, sub-coordinators only for wide areas (max three levels, ~10 in flight), forking for built state, a verifier from a different model family, and "start with one unit".
• Supervision: each kickoff names the evidence that proves done; read the diff, not the summary; send back scope drift; check live PR state with gh pr view/gh pr checks; judge stalls by pushes and PR activity; retry by cause; ask the user only for real decisions.
• State moves to the Cursor Project tracker/store plus PR and CI event subscriptions; scripts/orch/* is deleted.

How it was adapted for Devin

• skills/poteto-mode/playbooks/orchestrate.md follows the new Topology / Supervision / Reply shape.
• Kept Devin specifics: run_subagent via delegation.md, same-pin poteto-agent-* writers, root-provisioned worktrees, the local program-state.sh store, foreground-only resumes, bounded waves plus resume.md.
• Verifier "different model family" becomes a profile with a different model: pin.
• Fork becomes "resume a worker only for a follow-up on the same work" (Devin has no fork).
• New audit: docs/pstack-0.15.36-port-audit.md; release notes and version bumped to 0.9.1.

Not ported / uncertain

• Cloud workers (environment: "cloud"): run_subagent has no such field.
• Sub-coordinators: Devin only nests with a custom max-nesting profile, which this port doesn't ship. Could be added later as a deliberate choice.
• Project tracker and PR/CI event subscriptions: no Devin equivalent documented; replaced by the existing local store and on-demand gh checks.
• orch script deletion: never shipped here.
• Native Devin activation of 0.9.1 is untested.

Checks

• node --test tests/*.test.mjs: 53/53 pass.
• git diff --check: clean.
