governloop-dsh

Technical DSH adapter package for DSH-GPTLoop — The outer loop for DeepSeek Harness.

DSH-GPTLoop connects DeepSeek Harness (DSH) to a persistent GPT Web outer loop for project reasoning, independent review, and human authority. This package stays deliberately thin: DSH remains the fast local execution loop; GPT Web remains the persistent outer-loop reasoning surface; GovernLoop provides the bridge.

Native first. No second agent framework. No duplicated sandbox. No duplicated session system.

The outer loop can also become a cross-tool project context surface when the relevant systems are connected to GPT Web — for example research sources, Linear planning/issues, GitHub repositories / pull requests / CI evidence, documentation, and release-readiness work. Those systems retain their own authority; the adapter does not turn GPT Web into a universal execution or lifecycle authority.

Product explanation: ../docs/product/DSH-GPTLoop-outer-loop.md.

Version 0.1.0 — minimal vertical slice: BEFORE_DESTRUCTIVE_ACTION on destructive bash commands (git history-rewriting + rm -rf class). Design contract: docs/architecture/AGE-61-governloop-dsh-integration-architecture.md (Rev 2). Verified runtime assumptions: docs/spikes/AGE-63-dsh-runtime-verification.md.

DSH tool action (git push --force)
→ tools/pre-execute classifier deny + latch
→ agent/pre-step rejects while latch set (pause)
→ evidence → governloop_session.py → GPT Web review (structured envelope)
→ explicit human (PO) authorization via userQuestions
→ one-shot retry token (exact call, expiring)
→ verdict injected + followup (resume)

Authority model (non-negotiable)

• GPT Web review is advisory evidence only. It never authorizes execution.
• A destructive action may only run after explicit human (Product Owner) authorization mints a one-shot retry token bound to session + call fingerprint + exact command/args + expiry (default 10 min).
• Fail closed: an unknown/malformed/low-confidence review, a declined PO, a relay failure, or a timeout keeps the action blocked (session latch held). No automatic resend.
• DSH native sandbox, permissions, sessions, and approval behavior remain authoritative.
• Connected tools keep their own authority: GitHub for repository state, Linear for issue/project tracking when used, CI as verification evidence, and humans for consequential lifecycle authorization where required.
• GovernLoop Core remains agent-agnostic; this plugin only translates DSH events and carries evidence/verdicts through the governloop_session.py CLI seam.

Install

dsh plugin --profile <name> add governloop-dsh

Or mount locally (dev): dsh --profile <name> --patch <repo>/governloop-dsh/cordis.patch.yml "…" with GOVERLOOP_SESSION_MANAGER_PATH (or config.sessionManagerPath) pointing at governloop_session.py.

Config (cordis.patch.yml row)

Key	Default	Meaning
sessionManagerPath	env GOVERLOOP_SESSION_MANAGER_PATH	session-manager executable (preferred; P1 path-contract fix)
relayPath	(config only)	DEPRECATED config-only alias for the session-manager path. GOVERLOOP_RELAY_PATH is no longer a session-manager fallback — it belongs exclusively to Core's Neutral Relay
stateDir	env GOVERLOOP_STATE_DIR	GovernLoop session state dir
cdpPort	env GOVERLOOP_CDP_PORT	CDP port passthrough
tokenTtlMs	600000	one-shot retry token expiry
evidenceMaxEvents	20	rolling evidence buffer size
relayTimeoutMs	600000	relay wait bound
attachPaths	[]	evidence attachments (core validates/redacts)
allowRules	[]	exact command prefixes exempt from review (noise reduction only)
debugOut	''	lifecycle JSONL log (tests/ops)

Tests

node --test governloop-dsh/tests/unit.test.mjs governloop-dsh/tests/unit-gate.test.mjs governloop-dsh/tests/unit-relay.test.mjs
DSH_BIN=<pinned dsh binary> node governloop-dsh/tests/harness/run-e2e.mjs

• The E2E is keyless (scripted mock LLM adapter, stub relay, scratch DSH_HOME) and requires the pinned @deepseek-ai/dsh@0.1.1-rc.2 binary via DSH_BIN.
• Scenarios include approve (full chain), PO decline (blocked), relay failure (fail closed, no auto-resend), malformed review envelope (blocked), and malformed PO answer (blocked).

Closure confirmations (AGE-63 final review round, 2026-08-24)

• execution-plane governance: the gate is tools/pre-execute (allow/deny decision path). It is not a general argument-mutation hook. Result/evidence observation is tools/result plus durable tool/result; the evidence path never grants execution authority.
• DSH native enforcement stays authoritative: a GovernLoop allow only lets a call proceed through the normal DSH pipeline. The connector never calls setSandboxMode / setApprovalPolicy and never elevates DSH permissions.
• per-session isolation: latch / pending-checkpoint / retry state is keyed by DSH SessionId; no global approval state exists.
• ADR-13 headless provider: preserved — transport fallback only; never overwrites an active provider, never auto-approves, missing answer/provider fails closed, and cleanup restores only what it owns.
• token/grant: explicit human PO authorization → narrowly bound single-use grant → exact execution only; GPT review alone never authorizes; replay/reuse and mismatch fail closed.
• transport/control plane: ctx.apiProxy is DSH Host↔Client infrastructure, not the governance boundary.
