Human In The Loop

The primitive that treats humans as durable network participants — attention surfaces, queues, decision records, routing semantics — not as ad-hoc chat receivers.

Autonomy is not the absence of humans; it is knowing when human judgment is needed and making that handoff crisp.

Use this when

• A slice closeout needs classifying: auto-continue, human gate, or park
• A real decision needs to land in front of a human (usage limits, provider auth, roadmap tradeoff, product-intent ambiguity)
• Designing a human queue/dashboard surface
• Returning a hot potato to orchestration after human approval

Don't use this when

• The slice closeout is clean and PROGRESS.md already names the next safe slice. Default RSI conveyor continues; do NOT manufacture a human gate.
• The escalation is just a status update. Humans are participants for decisions, not narration.
• The next owner is another agent. Use queue-handoff, not human-in-the-loop.

The 3-class closeout classification

In a productized daemon-backed version, closeout classifies the next step BEFORE touching the human queue:

Class	When	Action
auto-continue	Slice closes cleanly, next named slice in workstream plan	Mark closed; create next-owner qitem from plan
human gate	Genuine decision needed (usage limits, provider auth, product-intent ambiguity, roadmap tradeoff)	Create human queue item with proof + decision text + recommended default + action outcomes
park	Intentionally stop the conveyor (e.g., waiting on external)	Stop with reason + resumption path

Failure modes (5)

1. Human decision needed, but the rig only mentions it in chat. Decisions belong as durable attention items, not chat messages.
2. Human queue item lacks enough plain-English context for a decision. Include proof + decision text + recommended default + action outcomes.
3. Human response updates a file but does not wake the next owner. Approval should return the hot potato; feedback should create the next durable qitem.
4. The dashboard shows too much raw rig state and hides the actual decision queue. Decision queue is the primary surface; rig state is secondary.
5. A clean closeout is parked on the human even though PROGRESS.md already names the next safe slice. Don't manufacture human gates.

Proof standard (both paths)

A trustworthy human-in-the-loop system proves both directions:

• Blocking gate path: real item routed to human → human decision recorded through UI → resulting hot-potato handoff wakes correct next owner
• Non-blocking closeout path: proof inspectable by human, but orchestrator continues to next named slice without manufacturing a human gate

A primitive that only wakes humans is not trustworthy. It must also know when NOT to.

Product shape (SHIPPED — Mission Control, PL-005)

This surface has shipped as Mission Control (product UI, /mission-control route; actions via POST /api/mission-control/action). The seven verbs the human acts with:

• approve (returns the hot potato to orchestration or the chosen owner)
• deny (reject the item)
• route (send to a different owner)
• annotate (add context without action)
• hold (intentional pause with reason)
• drop (mark not-actionable)
• handoff (hand to a specific next owner — creates the next durable qitem)

Approval returns the hot potato to orchestration or the chosen owner; feedback creates the next durable qitem rather than only mutating the source queue file — enforced by the shipped verbs (handoff/route create qitems). See docs/as-built/architecture/mission-control.md.

Long-term shape

Likely needs multiple humans with different scopes, not a singleton human attention feed. Different humans own different decision domains; queue items route by scope.
