# Codex: Human-in-the-Loop Design for Agentic AI > A living research reference assembled to ground the design of human-in-the-loop (HITL) > behavior for agentic LLM systems (coding agents, copilots, autonomous assistants). > It captures (1) what is known to work, (2) what people tried that failed, and > (3) the deeper ergonomics / human-factors / HCI traditions we can draw on. > > **Scope decision (2026-06-22):** center of gravity is *agentic LLM tools* — approvals, > interrupts, plan/preview, oversight of autonomous action — with classical automation, > human-factors, and HCI literature treated as transferable foundations. The codex is > meant to serve *both* as a cited research synthesis and as the substrate for an > actionable design framework (proposed separately). --- ## How to read this codex - **Part I** covers HITL specifically for AI/ML and agentic systems, plus governance mandates. - **Part II** covers the foundational ergonomics, human-factors, automation, and HCI literature. - **Part III** covers the theory of delegation, organization, and resilience (the principal–agent problem, management/military delegation doctrine, resilience engineering/HRO, and human–agent teaming). - **Part IV** mines other industries for concrete, battle-tested oversight *mechanisms* (manufacturing & process safety; finance & security). - **Part V** turns to the human side and the *design of a single loop episode* (the cognition of advice & decision fatigue; the anatomy of an oversight moment; sociotechnical context & workflow precedents). - Each thematic section opens with **Highlights** (the load-bearing takeaways) followed by an **Annotated bibliography**. ### Citation conventions References are recorded in an academic, lightly-numbered style, grouped by theme: > **[§-n] Author(s) (Year).** *Title*. Venue / Publisher. URL or DOI. > — Annotation: core contribution; what worked / what failed; relevance to agentic-LLM HITL. Empirical findings are distinguished from opinion/position pieces. Documented failures and anti-patterns are recorded alongside successes by design — knowing what *didn't* work is half the point of this codex. --- # Part I — Human-in-the-Loop for AI _(Annotated bibliography + highlights assembled below.)_ ## I.A — Agentic LLM HITL patterns (industry & framework practice) _How current agentic systems actually implement oversight. Tags: **[VENDOR]** primary docs · **[PRACTITIONER]** essay/postmortem · **[EMPIRICAL]** study._ ### Highlights - **Default to "ask," make "act" an explicit, graduated opt-in.** Every mature system (Claude Code, Copilot, Cursor, Operator) gates writes/side-effects by default and exposes a deliberate ladder to autonomy (`acceptEdits` → `bypassPermissions`; `/yolo`; auto-approve toggles). Trust is loosened *over time / within a session*, not granted up front [A-2, A-5, A-13]. - **The converged HITL primitive is interrupt → {approve / edit / reject / respond} → resume, built on durable state.** LangGraph, OpenAI Agents SDK, Google ADK, CrewAI, and Vercel all implement this; the non-negotiable substrate is a checkpointer/persistence layer — HITL and pause/resume are the same feature [A-8, A-7, A-10, A-11, A-12]. - **Approval gates reduce bad *actions* but do NOT make humans good at *catching* them.** Strongest empirical result here: plan-approval cut attack occurrence to 60–74% (from ~90%) yet intervention success stayed **9–26%** across all strategies — failure is rationalization/normalization (a "recognition bottleneck"), not inattention [A-17]. - **ANTI-PATTERN — rubber-stamping / automation bias.** Even motivated expert developers default to heuristic, shallow review under productivity pressure; "safety contingent on developer oversight" does not scale and externalizes correction cost onto the human [A-18, A-21]. - **ANTI-PATTERN — string-matching command denylists / client-side approvals as a security boundary.** Cursor's denylist was bypassed ≥4 ways (base64, subshells, generated scripts, quoting); Vercel documents that `needsApproval` is a UX affordance, forgeable via replayed history unless cryptographically bound. Pattern-matching guardrails are not sandboxes [A-14, A-12]. - **Sandbox the environment instead of gating every action.** Practitioner consensus for high-autonomy work: no-network containers, disposable cloud machines, scoped test/staging credentials, budget caps — move the safety boundary off the per-action prompt [A-23, A-3, A-1]. - **The "lethal trifecta" decides when an agent must NOT run unsupervised [A-23]:** private-data access + untrusted-content exposure + external-communication ≈ guaranteed exfiltration via prompt injection. Removing any one leg (read-only, no network) is the cheapest guardrail. - **Undo/rollback has a hard boundary at the shell [A-4].** Claude Code checkpoints structured edits but cannot undo Bash side-effects (`rm`/`mv`/`cp`) — the most destructive ops sit outside the recovery net. - **Models are genuinely weak at mid-task steering, cancellation, and re-planning [A-19, A-16].** "Steerable"/"interruptible" are model-capability claims, not just UI claims. - **Risk-tier tools to decide *what* to gate [A-6, A-12, A-5].** read-vs-write, reversibility, permissions, financial impact → low/med/high → auto-run the trivial, gate the consequential (e.g., value-conditional approval >$1000). - **Escalation-to-human as a first-class control, plus AI-supervising-AI for scale [A-15, A-6, A-10].** Treat the human as the escalation tier with a generated handoff summary — "human-on-the-loop," not per-turn "in-the-loop." - **Plan-then-confirm and disambiguate-before-acting is what expert users actually want [A-20, A-22].** Preview/diff-before-apply (plan mode) and clarifying questions before execution recur as the highest-trust pattern. - **Permission-rule precedence and inheritance are subtle and load-bearing [A-2].** Order matters (hooks → deny → ask → mode → allow → callback); allow-lists don't constrain bypass mode; subagents silently inherit a parent's bypass/acceptEdits — misconfiguration quietly grants more autonomy than intended. ### Annotated bibliography **[A-1] Anthropic (2024). [PRACTITIONER]** *Building Effective Agents.* Anthropic Engineering. https://www.anthropic.com/engineering/building-effective-agents — Distinguishes workflows from agents; minimal agent = "model + tools + system prompt in a loop." Frames HITL: pause at checkpoints/blockers, human-set stopping conditions (max-iteration caps). *Worked:* agent-computer-interface (ACI) design, "poka-yoke" tools, sandboxed testing, read-only as a cheap guardrail. *Limit:* autonomy → higher cost + compounding errors; HITL/read-only also cap scaling. *Relevance:* canonical statement of the autonomy-vs-control tradeoff and "pause at checkpoints." **[A-2] Anthropic (2026). [VENDOR]** *Configure Permissions (Claude Agent SDK).* https://code.claude.com/docs/en/agent-sdk/permissions — Most precise published permission spec: six-step pipeline **Hooks → Deny → Ask → Mode → Allow → `canUseTool`**, modes `default/acceptEdits/dontAsk/bypassPermissions/plan/auto`. *Worked:* deny/ask override even `bypassPermissions`; dynamic mode escalation mid-session. *Pitfalls (documented):* `allowed_tools` does NOT constrain `bypassPermissions`; subagents inherit bypass/acceptEdits and can't be re-tightened. *Relevance:* reference implementation of allow/deny/ask precedence — ordering and bare-name vs scoped rules change the safety semantics. **[A-3] Anthropic (2026). [PRACTITIONER]** *How We Built Claude Code Auto Mode: A Safer Way to Skip Permissions.* https://www.anthropic.com/engineering/claude-code-auto-mode — Two-layer classifier defense (input prompt-injection probe + output transcript classifier with fast single-token filter escalating to chain-of-thought). *Worked:* blocks "overeager behavior," "credential exploration," "scope escalation." *Limit:* **17% false-negative** on real overeager actions; classifier deliberately blinded to assistant reasoning/tool outputs (prevents "talking it into" approval but sacrifices provenance). *Relevance:* rare quantified data on automated gates substituting for the human — and an admission they don't fully replace one. **[A-4] Anthropic (2025). [VENDOR]** *Checkpointing (Claude Code) — /rewind.* https://code.claude.com/docs/en/checkpointing — Automatic per-edit snapshots; `/rewind` (Esc-Esc) restores code+conversation / conversation-only / code-only. *Worked:* transparent undo enables ambitious tasks; decoupling code-state from chat-state. *Critical limit:* does NOT track files changed by Bash (`rm`,`mv`,`cp`) — the most destructive ops are outside the undo boundary. *Relevance:* rollback pattern + its sharp boundary (undo covers structured edits, not shell side-effects). **[A-5] OpenAI (2025). [VENDOR + safety]** *Introducing Operator* & *Operator System Card.* https://openai.com/index/introducing-operator/ · https://openai.com/index/operator-system-card/ — Computer-use agent, three-layer oversight: autonomous by default; **user-confirmation gates** before side-effecting actions (Purchase/Send/Delete); **Takeover Mode** blacks out model vision on password/CC fields; refuses high-stakes categories. *Limit:* oversight concentrated at agent-chosen moments — missed risk depends on the agent's own risk detection. *Relevance:* reference design for "act autonomously, ask only at consequential moments" + sensitive-field takeover. **[A-6] OpenAI (2025). [PRACTITIONER]** *A Practical Guide to Building Agents.* (PDF) https://cdn.openai.com/business-guides-and-resources/a-practical-guide-to-building-agents.pdf — Risk-rate every tool (read-vs-write, reversibility, permissions, financial impact) to drive pause/escalation; "human intervention" as graceful control-transfer; matters most early to surface edge cases; layered guardrails (input → tool → HITL). *Limit:* prescriptive, not evaluated. *Relevance:* the canonical "risk-tier your tools, gate the high-risk" rubric. **[A-7] OpenAI Agents SDK (2026). [VENDOR]** *Guardrails and Human Review.* https://developers.openai.com/api/docs/guides/agents/guardrails-approvals — Tools set `needsApproval`; runs pause and surface `interruptions`; host calls `approve()`/reject and resumes from saved state. Input/output/tool guardrails with a defined firing order (tool-input guardrails run *after* approval by default; a flag inverts this). *Relevance:* the interrupt-inspect-resolve-resume loop as a first-class SDK primitive. **[A-8] LangChain/LangGraph (2026). [VENDOR]** *Human-in-the-Loop.* https://docs.langchain.com/oss/python/langchain/human-in-the-loop — Most-copied HITL abstraction: `interrupt()` pauses a graph node and returns a payload; four decision types **approve / edit / reject / respond**; resume via `Command(resume=...)`. Requires a checkpointer (HITL built on durable persistence). *Worked:* `when` predicates gate only risky calls; structured rejection feedback. *Limit:* heavy arg edits can trigger re-evaluation/re-runs; decision ordering must match action ordering. *Relevance:* the de-facto approve/edit/reject/respond vocabulary others mirror. **[A-9] Microsoft AutoGen (2025). [VENDOR]** *Human-in-the-Loop / UserProxyAgent.* https://microsoft.github.io/autogen/stable/user-guide/agentchat-user-guide/tutorial/human-in-the-loop.html — Models the human as an agent (`UserProxyAgent`) with a pluggable `input_func` (console/websocket/Slack); legacy `human_input_mode`: **NEVER / TERMINATE / ALWAYS**. *Relevance:* HITL as a *participant* in a multi-agent conversation rather than an interrupt on one loop; NEVER/TERMINATE/ALWAYS is an early autonomy slider. **[A-10] Google ADK (2026). [VENDOR]** *Action Confirmations & Long-Running Function Tools.* https://google.github.io/adk-docs/tools-custom/confirmation/ · https://developers.googleblog.com/build-long-running-ai-agents-that-pause-resume-and-never-lose-context-with-adk/ — Tool Confirmation (≥1.14): any tool pauses for yes/no or structured confirmation via a `FunctionResponse`; `LongRunningFunctionTool` returns `pending` and resumes on external human/webhook/queue response — pause/resume surviving across processes and time. *Relevance:* best-articulated pattern for *durable, asynchronous* approval (human may respond hours later). **[A-11] CrewAI (2026). [VENDOR]** *Human Feedback in Flows / human_input.* https://docs.crewai.com/en/learn/human-feedback-in-flows — Two tiers: task-level `human_input=True`; `@human_feedback` decorator (≥1.8) pauses a Flow, presents output, routes by outcome, loops until approved/rejected (typically via webhooks). *Relevance:* HITL as a review/approve loop at task/workflow boundaries with branching on the verdict. **[A-12] Vercel AI SDK (2026). [VENDOR]** *Tool Execution Approval — needsApproval (AI SDK 6).* https://vercel.com/blog/ai-sdk-6 · https://ai-sdk.dev/cookbook/next/human-in-the-loop — Single-flag HITL: `needsApproval: true` inserts a gate before `execute`; function form enables conditional gating (e.g., payments >$1000); durable workflows can suspend for days. *Critical security caveat (documented):* by default the approval is a UX affordance, NOT a server-side boundary — forgeable via replayed message history; use `experimental_toolApprovalSecret` to bind it. *Relevance:* cleanest "conditional approval by input value" + explicit warning that a gate isn't a security control unless bound server-side. **[A-13] GitHub / VS Code (2025–2026). [VENDOR]** *Copilot Agent Mode & Copilot CLI Autopilot ("/yolo").* https://code.visualstudio.com/blogs/2025/02/24/introducing-copilot-agent-mode · https://docs.github.com/en/copilot/concepts/agents/copilot-cli/autopilot — Terminal commands require approval by default; autonomy opt-in via `chat.tools.autoApprove` / `terminal.autoApprove`, JetBrains "global auto approve," CLI `/allow-all` (alias `/yolo`). *Worked:* safe defaults + graduated path. *Risk:* JetBrains global auto-approve overrides per-category settings incl. destructive ops. *Relevance:* a mainstream IDE's "ask-by-default, opt into act" surface and its blunt-override risk. **[A-14] Cursor docs + Claburn, T. / The Register (2025).

Backslash Security found ≥4 denylist bypasses (base64-pipe, `bash -c` subshell, generated-script exec, quote variations), with malice arriving via poisoned rules.mdc / README / fetched content; denylist reportedly deprecated. *Failed:* pattern-matching denylists trivially evaded. *Relevance:* the cautionary case that string-matching command guardrails are not a sandbox. **[A-15] Sierra (2025). [PRACTITIONER]** *Confidence in Every Conversation* & *Enterprise-Grade Agents.* https://sierra.ai/blog/confidence-in-every-conversation · https://sierra.ai/blog/enterprise-grade-agents — Production CX stack: per-agent **Supervisors** ("a Jiminy Cricket") observe in parallel and shift observe→intercept (correct/redirect/escalate in real time); always-on **Monitors** score coherence/grounding/sentiment at scale; deterministic guardrails the agent "cannot cross"; escalation produces an AI summary for handoff. *Relevance:* a "human-on-the-loop + AI-supervising-AI" stack where the human is the escalation tier, not the per-turn approver. **[A-16] Cognition (2025). [PRACTITIONER]** *Devin's 2025 Performance Review: Learnings From 18 Months of Agents at Work.* https://cognition.com/blog/devin-annual-performance-review-2025 — Merge rate rose to 67% (from 34%); excels at clear-spec, verifiable, 4–8h tasks parallelizable as a fleet; async "first-pass" with humans reviewing only the final result. *Failed/anti-patterns:* iterative problem-solving + mid-task scope changes degrade performance; ambiguous/visual work needs explicit specs; bottleneck shifts from writing to reviewing. *Relevance:* evidence that async/end-of-task review beats turn-by-turn for some workloads, but interruptibility/steering remains weak. **[A-17] Chen et al.

[EMPIRICAL, interviews n=17]** *Human Oversight of Agentic Systems in Practice…* arXiv:2606.05391. — Documents the gap between intended and actual oversight: developers rely on informal heuristics rather than systematic verification; automation bias + productivity pressure produce rubber-stamping.

Tags: **[E]** empirical · **[O]** opinion/survey · **[E/O]** evidence-backed survey._ ### Highlights - **Confidence-gated human queries (uncertainty sampling, [B-1, B-2]) can cut labeling 10–500× — but the gains are fragile.** In real projects, utility-per-cost querying often fails to beat random sampling, and the "most informative" items are also the hardest and most disagreement-prone for humans [B-3]. *Lesson:* confidence-gated escalation is powerful but must account for human cost and difficulty, not just model uncertainty. - **Passive "label what the model asks" loops miss rare-but-critical cases [B-4].** A model "cannot be uncertain about a class it has never seen" — argues for human *initiative* (search/seeding), not only human *response*. - **Rich human feedback is double-edged.** Users gladly critique model reasoning [B-5, B-6] and explanation-mediated correction ~2× efficiency [B-7] — yet naive incorporation of human corrections can *degrade* accuracy [B-6]. - **Aggregation beats individual labels — up to a point [B-9, B-10].** A few cheap labels can match experts, but redundancy is wasted when labelers are good and assumes a single correct answer exists. - **Disagreement is often signal, not noise [B-13].** For subjective tasks there may be no single ground truth; majority-vote gold distorts data and eval. *Implication:* RLHF preference disagreement is partly irreducible. - **Agreement metrics measure consistency, not correctness [B-11].** High κ/α can encode shared bias. - **Crowdsourcing pathologies recur: spam, gaming, low effort, fatigue, demographic/task-design bias [B-12].** - **Programmatic / expert-in-the-loop supervision scales human effort [B-14, B-15].** Snorkel: ~2.8× faster, ~45% better than hand labeling — the conceptual bridge to LLM-assisted labeling. - **Preference-based RLHF is the scalable HITL primitive [B-16]:** humans compare, a reward model learns, the policy optimizes — feedback on <1% of interactions. Made oversight of deep RL and then LLMs affordable [B-17, B-18, B-19]. - **Reward hacking / over-optimization is the signature failure mode [B-17, B-22].** Optimizing too hard against an imperfect learned reward makes true human-judged quality go *down* (Goodhart); mitigations: KL penalties, early stopping, reward-model ensembles. - **The human-feedback pool is a narrow, contestable foundation [B-18, B-21].** InstructGPT's "good" was set by a small labeler group (~72–77% agreement); annotator bias/error/non-representativeness are partly *fundamental* limits. - **RLAIF / Constitutional AI [B-20] shifts humans from labelers to rule-authors** — scaling oversight but inheriting the base model's blind spots.

Book summarization [C-7] is the clearest proof it works on a real task. - **Debate works — but less than the hype, and only in the right conditions.** Persuasive-debater results encourage [C-10]; the broadest benchmark finds gains modest, task-dependent, and shrinking as the human's own information grows [C-11]. Debate assumes a competent, unbiased judge — its key vulnerability. - **Constitutional AI/RLAIF reduce the oversight *burden* partly by removing the *human* [C-8].** Substituting an AI judge scales but relocates risk into the constitution's quality and the AI evaluator's blind spots. - **Weak-to-strong generalization makes superhuman oversight studiable today — and shows naive supervision is insufficient [C-12].** Strong students beat weak teachers but recover only part of the gap; combining with debate helps [C-13]. - **FAILURE MODE — over-reliance / rubber-stamping is the default.** Automation bias yields omission + commission errors [C-14]; complacency afflicts experts and resists practice [C-15]; people over-trust advice *because* it's labeled algorithmic [C-16]. - **FAILURE MODE — explanations cause over-trust, not better oversight [C-17, C-18].** Transparency aimed at empowering the overseer can instead disarm them. - **What actually curbs rubber-stamping: friction [C-18].** Cognitive forcing functions (commit-before-seeing-AI, mandatory deliberation) measurably reduce over-reliance — but they're slower, unpopular, and help analytical users most. - **FAILURE MODE — adding a human can make the team worse [C-19].** Meta-analytically, human–AI combinations often underperform the better of human-or-AI alone, especially in decision tasks and when the AI is stronger. - **FAILURE MODE — illusory oversight / accountability laundering [C-21].** Mandating an overseer who cannot in practice oversee legitimizes flawed systems and creates a moral crumple zone. - **Meaningful control demands tracking + tracing, not a button [C-2, C-20].** The system must respond to relevant human reasons and outcomes must trace to an informed, responsible human — a far higher bar than a veto checkbox. - **Assume the model may be adversarial: monitor, don't just align [C-22].** AI-control protocols stay safe against intentional subversion by routing scarce human/trusted-model review to flagged actions — the most operationally concrete HITL strategy here. ### Annotated bibliography **[C-1] Amodei, D., Olah, C., Steinhardt, J., Christiano, P., Schulman, J., & Mané, D.

Tags: **[LEGAL/STANDARD]** · **[CRITIQUE]** · **[EMPIRICAL]**._ ### Highlights - **The law now demands oversight; the evidence says humans can't reliably deliver it.** EU AI Act Art. 14 [D-1] and GDPR Art. 22 [D-2] mandate human oversight/intervention, while 25+ years of empirics [D-18, D-19, D-20] show people systematically over-rely on automation and miss its errors — *especially* under load and high autonomy (the agentic regime). - **Regulators named the failure mode — then arguably legislated into it.** WP29/EDPB [D-4] explicitly bars **rubber-stamping** and requires reviewers with "authority and competence to change the decision," yet Art. 14's de-biasing strategy is largely to require *awareness* of automation bias — which [D-17] argues won't actually de-bias anyone. - **"Add a human" is a legitimacy device, not a control [D-14].** Oversight requirements often *launder* faulty algorithms with false confidence while diffusing accountability; agencies are rarely required to *prove* oversight works. Green's fix — shift the burden to demonstrate effectiveness — is the most actionable governance reform here. - **The human is frequently positioned to absorb blame, not exercise control.** Elish's **"moral crumple zone"** [D-16] and the **"MABA-MABA trap"** [D-15] warn that inserting a human creates *new* failure modes (scapegoating, deskilling, diffused responsibility) rather than curing algorithmic ones. - **Override authority can introduce bias, not remove it [D-24].** Judges' discretionary overrides of a risk tool produced *racial disparities* — human discretion is not a neutral corrective. - **Opacity structurally defeats oversight [D-25, D-22].** Black-box scores can't be meaningfully scrutinized by nominally-responsible humans — directly implicating agents whose reasoning is hard to inspect in real time. - **Accountability sinks are not hypothetical.** The Dutch benefits scandal [D-21] (toppled a government) and Australian Robodebt [D-23] (unlawful, ~470k wrongful debts) are large-scale demonstrations of automated decisions running with ineffective/complicit oversight — caught by courts/commissions, not the systems' own HITL. - **Standards give vocabulary and scaffolding but stop short of teeth.** NIST AI RMF + GenAI Profile [D-5, D-6] name overreliance/automation bias and tie oversight intensity to autonomy; ISO/IEC 42001 & 23894 [D-7, D-8] give certifiable governance — but all are voluntary, outcome-based, and leave "does this human actually control anything?" to the deployer. - **Oversight language is engineered to be slippery.** DoD 3000.09 [D-11] chose "appropriate levels of human judgment" over "meaningful human control"; OECD/UNESCO/ICRC [D-9, D-10, D-12] endorse retained control but are non-binding (ICRC's *predictability + timely intervention/deactivation* is the most operational). - **There is a usable design target [D-13]:** **tracking + tracing** reframes control as reason-responsiveness plus traceable human accountability — a better spec than "a person can press stop." - **Net takeaway:** treat human oversight as a **claim to be empirically validated, not a checkbox**. Effective oversight needs (a) a genuinely empowered reviewer with authority *and* competence to override, (b) inspectable agent reasoning, (c) intensity scaled to autonomy/stakes, (d) defenses against automation bias/deskilling, and (e) accountability that doesn't collapse onto a lone crumple-zone human. ### Annotated bibliography — Part A: what regulators & standards require **[D-1] European Parliament & Council (2024).

(Northpointe disputed the methodology — the calibration-vs-error-rate fairness debate.) --- # Part II — Ergonomics, Usability & Human-Factors Foundations ## II.E — Automation theory & human-factors foundations _The classical foundations agentic AI should inherit._ ### Highlights - **The fundamental irony (Bainbridge, [E-7]) applies verbatim.** Automating the routine work an agent does well *increases* the difficulty and stakes of the human's leftover job — monitoring for rare failures and recovering from them. Designing for the happy path while ignoring the human's degraded oversight role is the original sin. - **Reliability is double-edged [E-17, E-18].** The more dependable an agent, the *less* the human monitors it, so the rare confident error slips through. Better models make complacency easier; pair reliability with deliberate engagement. - **The out-of-the-loop problem is the central HITL hazard [E-13].** Full autonomy maximizes the takeover penalty; intermediate levels that keep the human in the active decision loop preserve takeover ability. Prefer "human *in* the loop" to "human *on* the loop" for high-consequence actions. - **Autonomy is a dial, not a switch — and there are several dials [E-4, E-6].** Decide *which stage* (acquire → analyze → decide → act) and *what level* (suggest → act-with-approval → act-then-notify → act-silently) independently. Automating the *decision/action* stage is where over-trust and lost authority bite hardest; automate perception/analysis more freely than action. - **Measure the failure case, not the happy path — the "lumberjack effect" [E-15].** Higher autonomy buys small routine gains but, past a threshold, catastrophic recovery failures. Evaluate agents on what happens *when they're wrong*. - **Calibrated trust is the goal — both over- and under-trust fail [E-16, E-19].** Misuse (blind acceptance), disuse (alarm fatigue), abuse (automating because you can). Communicate capability, process, purpose, and uncertainty so reliance tracks competence. - **Automation bias replaces judgment, not just effort [E-20].** Confident recommendations induce omission + commission errors. Preserve independent verification, especially for irreversible/commission-type actions. - **Opacity breeds dangerous mismatches [E-10].** Mode confusion / automation surprise come from divergence between the human's model and reality. Make the agent predictable, its state visible, its actions explainable. - **Situation awareness, not activity logs, is what overseers need [E-12].** Effective intervention requires comprehension (L2) and projection (L3), not just perception (L1). Feed understanding and what-happens-next, not a stream of tool calls. - **Skill atrophy is selective and quiet [E-22].** Routine skills survive disuse; the higher-order *judgment* skills needed for non-routine takeover decay unless the human stays engaged. Keep humans reasoning, not rubber-stamping. - **Beware "clumsy" agents [E-11].** Agents that demand fiddly setup or grab attention at the busiest moments redistribute workload badly. Design the *interaction* and its timing, not just the capability. - **Aim for complementarity; keep the human informed and in command [E-3, E-21].** Reject leftover-allocation thinking for human-centered, congruent design. After ~45 years [E-7→E-9] the ironies remain unsolved — engineer around them; don't expect capability gains to dissolve them. ### Annotated bibliography **[E-1] Fitts, P. M. (Ed.)

Make the agent's competence, process, and purpose legible so reliance tracks reliability. - **Four pathologies as a diagnostic checklist.** [F-2] **Misuse** (over-reliance), **disuse** (neglect, usually from false-alarm fatigue), and **abuse** (deploying autonomy without regard for human consequences) map cleanly onto agentic-LLM risks — and *abuse* locates much fault in design/deployment, not the operator. - **Automation bias = heuristic deference.** [F-9, F-10] Users substitute "the system says so" for vigilant processing, producing **omission errors** (missing what the agent didn't flag) and **commission errors** (following the agent against contradictory evidence). Afflicts experts and crews alike, incl. false-memory ("phantom memory") that the agent was correct. - **Complacency is structural, attention-driven, and training-resistant.** [F-4, F-5, F-7] Reliable automation under multi-task load erodes monitoring (decrement in ~20 min); appears in experts; and **instruction/training does not reliably fix it**. "Tell users to stay vigilant" is not a mitigation. - **The automation conundrum / out-of-the-loop problem.** [F-8] The more autonomous and reliable the agent, the lower the human's situation awareness and the weaker their ability to take over when it finally fails — exactly when takeover matters most. - **Mode confusion & automation surprise.** [F-14, F-15] "What is it doing? Why? What next?" arises from poor **observability** + mental-model gaps; "strong, silent, clumsy" automation yields slow **"going sour" accidents.** Agents that silently switch tools/strategies/modes are surprise generators. - **There is a reliability floor (~70%).** [F-16] Below ~70% diagnostic reliability an advisory agent can be **net-negative** vs. no automation. Know the task's floor before deploying autonomy. - **False alarms are uniquely corrosive.** [F-17, F-18] False-alarm-prone systems damage *both* compliance and reliance and drive **alert fatigue** ("cry wolf") — desensitization that leads users to override even critical alerts. Alert precision and volume are safety parameters. - **Trust has three layers — design for each.** [F-3] **Dispositional** (who the user is), **situational** (context/workload/task), **learned** (onboarding + dynamic in-session updating). - **Explanations can backfire.** [F-20] Rationales (and by extension chain-of-thought) tend to **increase acceptance regardless of correctness**, deepening over-reliance. Explanations must support *verification*, not just persuade. - **Structural friction beats exhortation.** [F-12, F-21] **Cognitive forcing functions** (decide before seeing the AI's answer; deliberate friction) and **experiencing the agent fail during onboarding** measurably reduce over-reliance — but users dislike the friction that helps most. - **Accountability is an evidence-based debiasing lever — but token HITL is a trap.** [F-11] Felt accountability for decision *accuracy* reduces automation-bias errors; yet [F-19] **"moral crumple zones"** warn that a human nominally in the loop *without real authority/awareness* is just a scapegoat. ### Annotated bibliography **[F-1] Lee, J.

Act autonomously only when expected utility is clearly positive; otherwise ask, suggest, or defer. - **Pursue high automation AND high human control simultaneously [G-4].** Reject the false tradeoff (Shneiderman's 2-D HCAI). Target the RST quadrant: an agent that does a lot while the human stays in command. Watch both failure modes — over-automation (lost oversight) and over-control (no leverage). - **Continuous intelligibility prevents handoff disasters [G-12, G-17].** The danger isn't "too much automation," it's *silent* automation with poor feedback. Keep the human informed throughout — what the agent knows, how it knows it, what it's doing — so takeover at the competence boundary is safe. - **Close both gulfs [G-11].** Make available actions discoverable (Gulf of Execution) and state/reasoning/effects legible (Gulf of Evaluation). Supervision is impossible without both. - **Prefer reversibility over confirmation [G-13, G-14, G-15].** Undo beats warnings — confirmations habituate users into clicking through. Make agent actions reversible by default; reserve confirmation gates for genuinely irreversible, high-stakes operations. Always provide a cheap "emergency exit." - **Design the four phases explicitly [G-7, G-8].** *Initially:* disclose what the agent can do and how well. *During:* time interventions to context, show relevant info, respect norms. *When wrong:* efficient invocation, dismissal, **correction**; scope/hedge when in doubt; explain *why it did that*. *Over time:* learn cautiously, provide **global controls** + change notifications. - **Calibrate trust to true reliability [G-9, G-10].** Set accurate mental models; never overpromise. Label when AI is acting; make suggestions trivially easy to review, override, or modify. - **Design for graceful failure [G-9, G-12, G-13].** Assume the agent will be wrong. Build plain-language recovery, constructive remedies, safe fallbacks — not dead ends or silent failure. - **Augment, don't replace [G-3, G-5, G-10].** Frame the agent as a **supertool / tele-operated device / active appliance** that amplifies a human — not a human-substitute. Keeps responsibility and mastery with the person. - **Progressive disclosure reconciles simplicity with power [G-16].** Default to a simple, trustworthy interaction; tuck autonomy levels, tool permissions, and reasoning traces one layer down for power users. - **Protect the human's work and acknowledge latency [G-15].** For long-running tasks: immediate acknowledgment, autosave/preserve in-progress state, keep operations explorable/reversible. - **Enforce accountability for consequential acts [G-6, G-17].** Surface inferences and keep an identifiable human answerable — backed by layered guardrails (reliable engineering practice → org safety culture → external oversight). ### Annotated bibliography **[G-1] Horvitz, E.

Two imperatives: **Intelligibility** (represent what it knows, how, and what it's doing) and **Accountability** (enforce user accountability rather than acting opaquely). *Relevance:* the conceptual root of "explainable, controllable agents" — expose inferences; keep a human accountable for consequential acts. ## II.H — Adjacent safety-critical domains (aviation, medical, AVs, control rooms) _Tags: **[INCIDENT]** accident investigation · **[STUDY]** empirical/review · **[STANDARD]** standard/guidance._ ### Highlights - **The handoff problem is the central HITL failure mode.** AF447, Asiana 214, Uber Tempe, the Tesla crashes, and the L3 takeover meta-analysis converge: abruptly handing control to a disengaged human at the worst moment fails. Re-engagement takes **1.5–3.5+ s** (competence longer), grows with disengagement, and often arrives too late. Design handoffs *anticipatory, gradual, context-rich* — and accept that for time-critical failures the human fallback may not be viable. - **The "last line of defense" / human-safety-driver fallacy.** A human kept nominally responsible but operationally idle is the *least* reliable safeguard because reliable automation induces disengagement [H-16, H-17, H-18]. Oversight requires *active, verified engagement*; gameable engagement checks provide the illusion, not the substance. - **Alert fatigue is quantified and severe.** Clinicians override **49–96%** of drug-safety alerts [H-10]; TMI dumped **100+** unprioritized alarms in minutes [H-20]. Indiscriminate flagging trains humans to dismiss *everything*, including the rare valid signal. Reserve interruptive/blocking interventions for high-severity cases; make the rest passive. EEMUA: every alarm must demand a *defined response*; cap the interruptive rate [H-21]. - **You can't safely fix alert fatigue by muting the noisiest signals [H-11].** Rare-but-critical cases hide in high-override categories. Reduce volume by per-case risk stratification/tiering, not blanket suppression. - **Skill decay is real and measured [H-9, H-1].** Heavy automation erodes the underlying skill (errors in ~60% of studied cases). A human who never performs the task can't meaningfully review an agent that does — build in deliberate manual practice. - **Out-of-the-loop = lost comprehension, not just lost data [H-3].** Showing logs/raw output isn't enough; the human needs to retain comprehension of what the agent is doing and *why*. Intermediate automation preserves takeover ability better than full autonomy with a passive monitor. - **Over-trust and under-trust are one calibration problem [H-2].** Even experts are biased by confident-but-wrong AI recommendations [H-13]. Calibrate trust to *actual* reliability; surface confidence/uncertainty honestly. - **Mode confusion is first-class for agents with multiple states/permissions [H-5].** Users must always know what the agent is doing and under what authority *right now*. Silent transitions (suggest→act; a guardrail silently disabled) are the cockpit mode errors behind Asiana 214 [H-8]. - **Select the appropriate level of automation — and make stepping *down* easy [H-6].** "Children of the magenta line": the failure is uncritically riding maximum automation into task saturation. - **There is a hard ceiling on supervisory span [H-22].** One operator caps at a handful of actively-supervised agents; performance collapses past ~70% utilization. Scaling agent count without scaling/pooling oversight guarantees unmonitored failures. - **Crisis is exactly when the firehose hurts most [H-20, H-7].** At overload, prioritize, aggregate, and interpret *for* the human — don't dump everything. - **Validate the human–system combination, with realistic misuse [H-14, H-16].** Safety is a property of the whole socio-technical system; test against real, over-trusting users — and don't let an org offload safety responsibility onto a single monitor. ### Annotated bibliography **[H-1] Bainbridge, L.

[INCIDENT]** *Collision Between Developmental ADS Vehicle and Pedestrian, Tempe, AZ, 18 Mar 2018.* NTSB/HAR-19/03. https://www.ntsb.gov/investigations/AccidentReports/Reports/HAR1903.pdf — First pedestrian fatality by a self-driving car: misclassification + "action suppression" delayed braking; the safety driver was on her phone; NTSB cited deficient safety culture and unmanaged automation complacency. *Transferable lesson:* the "human safety driver as last line of defense" is a fallacy when the system is reliable enough to induce disengagement but not enough to trust. **[H-17] NTSB (2017). [INCIDENT]** *Tesla Autopilot, Williston, FL, 7 May 2016.* NTSB/HAR-17/02. https://www.ntsb.gov/investigations/AccidentReports/Reports/HAR1702.pdf — Probable cause included driver inattention from over-reliance, *enabled by a design that permitted prolonged disengagement* and use outside intended conditions. *Transferable lesson:* if an agent *allows* the human to check out, they will — over-reliance is a predictable product of permissive design; constrain use to the operational design domain. **[H-18] NTSB (2020). [INCIDENT]** *Tesla Autopilot, Mountain View, CA, 23 Mar 2018.* NTSB/HAR-20/01. https://www.ntsb.gov/investigations/AccidentReports/Reports/HAR2001.pdf — Autopilot steered into a gore-point barrier; driver playing a game; NTSB found no *effective* driver-engagement monitoring and inadequate alert timing. *Transferable lesson:* token engagement checks (trivially gamed hands-on-wheel nags) aren't oversight — verify *meaningful* engagement. **[H-19] Zhang, B., de Winter, J., Varotto, S., Happee, R., & Martens, M.

[INCIDENT]** *Report on the Accident at Three Mile Island.* U.S. GPO. https://www.threemileisland.org/downloads/188.pdf — **100+ alarms** with no prioritization/suppression, poorly arranged indicators, contradictory feedback → wrong operator actions; absent the HF failures it would have been minor. *Transferable lesson:* the original alarm-flood disaster — dumping everything at once *disables* oversight. Prioritize, aggregate, and interpret *for* the human at the moment of overload. **[H-21] EEMUA (2013). [STANDARD]** *Publication 191: Alarm Systems — A Guide to Design, Management and Procurement* (3rd ed.). https://www.eemua.org/Products/Publications/Print/EEMUA-Publication-191.aspx (paywalled; existence verified) — Defines an alarm as something requiring a *specific operator response*; target ≤~10 alarms / 10 min / operator; alarm rationalization to delete/downgrade nuisance alarms. *Transferable lesson:* a quantified discipline for keeping oversight signals within human capacity — every agent "flag" should demand a defined action; cap the interruptive rate; everything else is a passive log. **[H-22] Cummings, M. L., Bruni, S., Mercier, S., & Mitchell, P. J. (2007). [STUDY]** *Automation Architecture for Single Operator, Multiple UAV Command and Control.* The International C2 Journal 1(2), 1–24. http://www.dodccrp.org/files/IC2J_v1n2_01_Cummings.pdf — Span of control rises with autonomy (~4–5 active, up to ~12 supervisory), but operator **utilization above ~70%** triggers sharp performance decay; high autonomy/rapid re-planning erodes SA and breeds complacency. *Transferable lesson:* a hard ceiling on how many agents one person can meaningfully supervise — scaling agent count without scaling/pooling oversight is a predictable path to unmonitored failures. --- # Part III — Delegation, Organization & Resilience _The theory of delegating to, organizing around, and staying safe with an autonomous agent — the formal backbone the first two parts lacked._ ## III.J — Delegation: economics & law _A human delegating to an LLM agent **is** a principal–agent relationship; a century of economics and agency law already maps its failure modes and the price of oversight. Tags: theoretical / legal-doctrine / AI-application._ ### Highlights - **A human delegating to an LLM agent is, formally, a principal–agent relationship [J-1, J-2].** The failure taxonomy — divergent objectives, hidden action, hidden type, costly observation — is already mapped; HITL is the *monitoring* term in a century-old equation. - **Oversight is costly monitoring, and total agency cost can never hit zero [J-2].** Jensen–Meckling's *monitoring + bonding + residual loss* reframes HITL as *minimizing total cost*, not maximizing control: human review = monitoring; guardrails/evals = bonding; tolerated errors = residual loss. - **"Management by exception" is the optimal response to monitoring cost [J-7].** Because informative signals have decreasing marginal value, review only the diagnostic exceptions — the economic justification for selective, risk-triggered HITL over uniform review. - **Observability of the agent's *process* is provably valuable — log the trace [J-7].** Holmström's informativeness principle: any signal informative about the agent's *action* strictly lowers agency cost. Traces/tool-call logs/chain-of-thought are exactly those signals. - **Measuring one thing distorts the rest — Goodhart has an economic theorem [J-10].** The multitask result: strong incentives on a measurable sub-goal degrade unmeasured ones → low-powered incentives + task/job-design limits. Over-tuning to one eval is structurally wrong; reward-hacking is predicted. - **You can't specify everything, so the real choice is who holds residual control [J-8, J-9].** Incomplete-contracts theory: power lives in the override / final-decision right for unforeseen states. HITL *is* the assignment of residual control rights; selective intervention (halt, revoke access, substitute) is the operative form of control. - **Behavior-based vs. outcome-based oversight is a contractible choice [J-5].** When behavior is observable/cheap to monitor, supervise the *process*; else contract on *outcomes* and bear the risk. Tells you whether HITL inspects steps or only final outputs. - **Trust starts before runtime: agent/model selection is an adverse-selection problem [J-6].** Evals/reputation/screening are the "lemons" remedy; monitoring after delegation does not substitute for screening what you delegate to. - **Authority must be scoped — and an agent can bind you beyond its scope [J-13].** Actual vs. *apparent* authority; ratification. Permission scoping is the technical twin of scope-of-authority; accepting an out-of-scope action ratifies it. - **The principal is generally liable for the agent's in-scope acts [J-14, J-19].** Respondeat superior routes responsibility to the operator; narrowing scope is both a safety control and the primary liability lever. Since the agent has no intent, the law puts the human principal on the hook. - **Some duties are non-delegable — the law itself can mandate a human in the loop [J-15, J-16].** Outsourcing a task doesn't outsource accountability; fiduciary *loyalty* + *care* supply the normative target for "alignment." - **The AI-specific literature already translates all of this [J-17, J-18, J-19].** ### Annotated bibliography **[J-1] Ross, S.

[legal-doctrine]** *Restatement (Third) of Agency.* ALI. — Distinguishes **actual** vs. **apparent** authority and **ratification**: a principal can be bound by acts it never authorized (if it created the appearance) and can ratify after the fact. *Relevance:* an agent acting beyond scope may still bind its operator; accepting an out-of-scope action ratifies it.

[legal-doctrine]** *Respondeat Superior / Vicarious Liability.* law.cornell.edu/wex/respondeat_superior. — Principal is liable for an agent's wrongful acts within the scope of agency. *Relevance:* liability flows to the operator for in-scope acts; narrowing scope is the principal's main liability lever. **[J-15] Cornell LII, Wex (+ Restatement (Third) §7.06). [legal-doctrine]** *Non-Delegable Duty.* law.cornell.edu/wex/vicarious_liability. (treated within vicarious-liability material) — Some duties cannot be offloaded; the principal stays liable regardless of who performs the act. *Relevance:* a hard legal limit on automation — certain decisions are non-delegable to an AI, mandating a human in the loop. **[J-16] Cornell LII, Wex (+ Restatement (Third) §§8.01–8.08). [legal-doctrine]** *Fiduciary Relationship.* law.cornell.edu/wex/fiduciary_relationship. — Agency is inherently fiduciary: duties of **loyalty** (act solely in the principal's interest) and **care** (competence/diligence). *Relevance:* the normative target for "alignment" in law — an aligned agent discharges loyalty + care. **[J-17] Kolt, N.

[legal/AI-application]** *The Law of AI is the Law of Risky Agents Without Intentions.* University of Chicago Law Review Online. — Since AI agents lack intent, *ascribe* intent (foreseeable consequences) and impose *objective* reasonableness on the humans/orgs who deploy them. *Relevance:* resolves the "agent can't form intent" objection by routing accountability to the human principal — a legal warrant for oversight obligations. ## III.K — Delegation: doctrine & management _How organizations and militaries delegate by intent and boundaries rather than step-by-step control._ ### Highlights - **Specify intent + boundaries, not steps** — the most cross-validated lesson [K-7, K-8, K-6, K-19, K-20]: brief with *purpose + desired end-state + constraints*, then delegate method. Mission orders state "results to attain, not how." - **Management by exception is the default oversight posture [K-1]:** handle the routine autonomously, escalate only deviations. Tune **active** (tight tripwires) vs **passive** (intervene on failure) by risk tier [K-2], with measured cost trade-offs [K-3]; avoid drifting into laissez-faire. - **Pre-authorize action limits in advance [K-12, K-13].** Rules of engagement are decisions made *before* the moment; encode an agent's always-allowed set and prohibitions as a structured, condition-keyed, machine-checkable policy. - **Bound to enable, not just to restrict [K-14].** Over-tight/ambiguous boundaries degrade initiative and tempo; clear boundaries are a force enabler. - **Span-of-control ceilings cap multi-agent oversight [K-4, K-5]:** coordination load grows geometrically (~5–6 interdependent subordinates). Cap concurrent agents per supervisor or decouple them (loose coupling + homogeneity) to widen the safe span. - **Autonomy is a dial, not a switch [K-15]** — assign each action class a Level of Automation; **adjustable autonomy** [K-17, K-18] makes the dial runtime-tunable via policy. - **Make agents directable, observable, predictable (OPD) [K-16]:** team effectiveness comes from supporting *interdependence*, not maximizing independence. - **Escalation should be a cost-aware policy [K-18]:** "act vs. hand back to the human" weighs expected cost of a wrong autonomous act against the cost/delay of interrupting — the formal trigger logic behind management-by-exception. - **Pair autonomy with shared context [K-10]:** "empowered execution without shared consciousness is dangerous." Grant autonomy only alongside rich briefing. - **Orientation beats raw speed [K-11]:** Boyd's OODA — invest in the agent's context/tools/memory (Orient) before letting it run faster loops; humans add most value in framing. - **Govern with policy, not micromanagement [K-17]:** runtime-adjustable authorizations + obligations as the control surface — "highest useful autonomy at acceptable trust." - **Honor intent over literal instruction [K-9]:** the "duty to deviate" — an agent should optimize for *stated intent* when literal instructions conflict — but only when observability/directability let the human catch misjudgments. ### Annotated bibliography **[K-1] Taylor, F.

[practitioner]** *Commander's Intent in management practice.* Thinkers50; DBM. — Documents the civilian crossover: a concise purpose + end-state lets decentralized teams improvise while aligned. *Relevance:* intent-based bounding is a general, business-tested technique — lowers the bar to adopt it for agent briefing. ## III.L — Resilience engineering, HRO & accident theory _Agentic systems are tightly-coupled, complex socio-technical systems; this is the discipline that studies how such systems fail and stay safe._ ### Highlights - **Tight coupling + interactive complexity = the danger zone (Perrow, [L-10]).** Multi-agent pipelines with chained tool calls and little slack sit in the "normal accident" regime. The structural fix is to **decouple**: human checkpoints, reversibility, rate limits, circuit breakers, so failures can't propagate faster than humans can intervene. - **Latent failures live at the blunt end (Reason, [L-12, L-13]; Leveson, [L-14]).** An agent's bad output is the *active* failure; the leverage is in latent conditions — prompt/tool design, eval coverage, permission scopes, gate placement. HITL is defense-in-depth, not catching every error. - **Drift and migration are silent and continuous (Rasmussen, [L-15]; Dekker, [L-17]).** Efficiency/effort pressure pushes systems toward the safety boundary via locally reasonable decisions. "Reduce human friction / the agent is good enough now" is textbook migration — counter with explicit, monitored counter-gradients. - **Normalization of deviance erodes HITL standards one success at a time (Vaughan, [L-16]).** Each un-reviewed action that "gets away with it" raises tolerance for un-reviewed actions. Track the *trend* in oversight bypasses, not just incidents. - **Deference to expertise is the keystone HITL principle (Weick & Sutcliffe, [L-7]; Rochlin et al., [L-9]).** Authority should migrate in real time to whoever has the relevant situational knowledge — human or specialized checker — independent of the default automation hierarchy. - **Design for things going right — Safety-II (Hollnagel, [L-1, L-2]).** Instrument the system's successful and recovered trajectories and near-misses, not only post-incident forensics. The human is a source of resilience, not an error term to design out. - **The four cornerstones map onto an oversight architecture (Hollnagel et al., [L-5]):** respond + monitor = runtime guardrails + anomaly detection; anticipate = red-teaming/evals; learn = incident review feeding updates. All four are necessary. - **Robustness ≠ graceful extensibility (Woods, [L-6]).** Handling anticipated faults ≠ handling surprise; LLM agents fail suddenly past their competence envelope. Humans supply graceful extensibility for novel situations. - **Redundancy can backfire (Sagan, [L-11]).** Stacking automated checkers adds interactions, diffuses responsibility, and manufactures false confidence; an incident-free record may be luck. - **Optimizations are the seed of failure — ETTO (Hollnagel, [L-3]).** Every speed/cost optimization (skipped checks, cached judgments, fewer gates) is an efficiency-for-thoroughness trade — make it explicit and monitored. - **Treat safety as control; keep the controller's model accurate (Leveson STAMP, [L-14]).** The human is a controller whose authority and situational awareness must stay adequate; STPA can derive *where* a human gate is needed. - **"Human error" is a symptom, not a verdict (Dekker, [L-18]); beware the ironies of automation (Hollnagel & Woods, [L-19]).** Don't design HITL as a blame-sink; if the agent escalates only the hardest cases, the human gets the toughest decisions with the least context. ### Annotated bibliography **[L-1] Hollnagel, E., Woods, D.

(cross-ref [M] cluster) — Analyze human + automation as a single joint cognitive system; warns of the ironies of automation (automation handles easy cases, dumps degraded hard cases on the de-skilled human). *Relevance:* if the agent escalates only hard/ambiguous cases, the human faces the hardest with the least context — design the joint system so the human stays competent. ## III.M — Joint cognitive systems & human-autonomy teaming _The unit of design is the **joint human–machine system**, not the agent in isolation. An effective agent is a **team player**: observable, predictable, directable, sharing common ground._ ### Highlights - **Observability, Predictability, Directability (OPD) are the three core design requirements [M-1, M-5]** — and they are **bidirectional** (the human must also be observable/predictable/directable to the agent). - **Coordination is never free and never goes to zero [M-7, M-15].** The "fully autonomous" agent is a myth; automating a task *relocates* coordination work (often dumping it on the human at the worst moment). Design the coordination; don't pretend it away. - **"Teammate" beats both "tool" and "fully autonomous" [M-1, M-7, M-9].** A tool loads all coordination on the human; "full autonomy" fails at the boundaries. The teammate stance is the sweet spot. - **Interdependence, not autonomy, is the right organizing principle [M-5, M-6, M-8].** Map where human and agent depend on each other (Interdependence Analysis), then design to support it. "More autonomy" is the wrong goal. - **Plans are resources for action, not controllers of it (Suchman, [M-4]).** A rigid plan-executor breaks in open environments; design for situated re-grounding and graceful breakdown-and-repair. - **Common ground is a maintained state, not a one-time briefing [M-2, M-14].** It decays; breakdowns are normal; the design question is whether *repair* is cheap (least collaborative effort). Explains why LLM context/memory drift causes coordination failures. - **Team cognition lives in the interaction [M-11, M-12]:** shared understanding and team SA are built by anticipatory information-*pushing* and closed-loop comms. Agents that only answer when queried produce weak team SA. - **Individual task competence ≠ teaming competence [M-11].** Synthetic teammates can do the job yet fail as team members for lack of proactive, bidirectional coordination. - **Design for calibrated trust, not maximal trust [M-16].** - **Continual feedback preserves the human's situation awareness [M-15, M-17].** Silent automation pulls the human out of the loop, destroying oversight. - **The authority gradient must run both ways (CRM, [M-19]).** Humans need a low-friction path to challenge/override; a good agent should flag when it thinks the human is wrong. Closed-loop confirmation is a portable pattern. - **Evaluate the joint system, not the agent in isolation [M-3].** The metric is combined human+agent performance and the quality of the coupling — not the agent's solo benchmark. ### Annotated bibliography **[M-1] Klein, G., Woods, D.

Tags: [STANDARD] / [STUDY] / [PRACTITIONER]._ ### Highlights - **Stop-and-escalate on anomaly is the master primitive (Jidoka) [N-1, N-2, N-3].** Run autonomously on the happy path; the instant the agent detects it's outside its competence/confidence envelope, *halt itself and surface to a human* rather than ship a defect downstream. Detect-and-stop is enough; don't trust the agent to autonomously self-recover. - **Build quality in; don't inspect it in (Jidoka + Deming) [N-2, N-9].** You cannot review-your-way to a safe agent; oversight works best when execution trips the alarm at the moment of anomaly, not via end-of-line audit. - **Make bad actions impossible, not merely discouraged (Poka-yoke) [N-6, N-7].** Prefer capability removal (least-privilege, sandbox, read-only, schema/type constraints) over denylists. A guardrail the agent *can* circumvent is policy; a poka-yoke removes the capability. - **Use the mistake-proofing hierarchy to rank guardrails [N-7]:** prevention (impossible) > detection/warning (flagged instantly) > human vigilance (weakest). Never rely on "the human will watch carefully" as the primary defense. - **Universal, cheap, blameless interrupt authority (Andon) [N-4, N-5].** Every party — supervising human, monitor agent, guardrail, end user — must have a low-friction, always-available halt. If interrupting is costly or punished, it won't be used. - **Separate signal-and-summon from hard-stop (Andon) [N-5]:** an ambient "andon board" of agent status for awareness, *plus* a true blocking interrupt for hazards. - **Intervene on calibrated signal, not every wobble (SPC) [N-8].** Define human entry via metrics against *calibrated control limits* balancing over-reaction to noise vs. missing a real fault. - **Over-intervention is its own failure mode — tampering (Deming) [N-9].** Correcting on every fluctuation degrades the system and burns the human's attention. - **Gate the killer items at phase boundaries; keep gates short (Checklists) [N-10, N-11].** Structured pre-action verification at high-consequence transitions reduces harm — but only if brief (≈5–9 items). Bloated gates induce rubber-stamping. - **A gate is only as good as the attention it commands [N-12].** The Ontario study: a *mandated* checklist with weak engagement delivered zero benefit — the manufacturing/clinical proof of the codex's central finding. - **Scoped, expiring, named authorization for privileged actions (Permit-to-work) [N-13, N-14].** Replace standing "the agent can do dangerous thing X" with narrow, time-boxed grants tied to a named approver, plus an explicit "hand-back" to a safe state. - **Two truly-independent authorizers for irreversible actions [N-15, N-16].** Separation of duties; the proposer must not be the approver. Independence is everything — an agent re-reading its own work just confirms its bias; a double check is a backstop, never the primary control. - **Positively disable, don't politely pause (Lockout-tagout) [N-17].** Revoke tokens / kill the session / drop to read-only as a *structural* lock held by the person doing the work — capability revocation (lockout) beats a warning (tagout), codified into U.S. law. ### Annotated bibliography **[N-1] Ohno, T.

[standard]** *The Control of Hazardous Energy (Lockout/Tagout), 29 CFR 1910.147.* — Before servicing, every hazardous energy source must be **positively isolated and locked** de-energized, keyed to the worker, so it *cannot* be re-energized while they're exposed; lockout (physical) preferred over tagout (a warning tag). ~120 fatalities / 50,000 injuries prevented yearly. *Relevance:* before humans/processes touch a system an agent controls (or before maintaining the agent), *positively disable* its ability to act (kill session, revoke tokens, read-only) as a structural lock — capability revocation (lockout) > warning (tagout), codified in law. ## IV.O — Finance & security mechanisms (incl. runtime assurance) _Two domains with mature controls over fast autonomous action: markets (where algorithms already outpace humans) and security (which formalized scoped authority and the human's role). Includes Cranor (2008), a direct prior HITL framework._ ### Highlights - **Pre-action admission control beats post-hoc review [O-2, O-3].** Gate every action against scoped limits *before* execution at machine speed — humans and after-the-fact logs can't keep up with an autonomous actor. - **Two-party approval for high-grade actions (maker-checker) [O-1, O-10].** The proposer must not be the approver; split planning/approval/execution across principals. - **Circuit breakers (auto-halt on threshold) + kill switches (decisive manual stop) [O-6, O-7].** Auto-pause and require re-authorization when guard bands trip; provide a one-command panic stop usable without diagnosing root cause. - **Bound blast radius ("fat-finger" limits) and action rate (throttles) [O-3].** Cap per-action magnitude (max spend/deletions/recipients) and per-window action rate to break runaway loops. - **Knight Capital is the canonical agentic cautionary tale [O-4]:** a tiny config/dead-code error in a fast autonomous actor cost ~$440M in 45 minutes with no kill switch. Verify feature flags/dead code before deploy; stage rollouts; never deploy without an emergency stop. - **Least privilege + capabilities + zero-trust = scoped, per-request agent permissions [O-10, O-11, O-13].** Grant only what the task needs, deny by default, mediate *every* action, re-authorize each step in context. - **The confused deputy IS prompt injection [O-11, O-12].** An agent with ambient authority is weaponized by untrusted content flowing through the same channel as legitimate instructions. Defense = scoped request-bound capabilities + runtime mediation for irreversible actions *regardless of instruction source* + sub-agents not inheriting orchestrator authority. - **No standing privilege; elevate just-in-time, break glass loudly [O-14].** Sensitive scopes granted time-boxed behind approval and revoked; emergency elevation is auditable, alarmed, post-hoc reviewed. - **Runtime shields/Simplex = a verified monitor that vetoes the agent [O-17, O-18, O-19].** You can't formally verify an LLM, but you can verify a small guard; let the agent act inside a verified envelope and override on breach — a guarantee that holds even under injection, complementing the soft human gate. - **Human gates are a design variable, and they fatigue [O-15, O-16].** Many users click through badly-designed warnings; habituation sets in neurologically by the *second* repetition. Minimize interrupts (auto-handle low-risk), and make the rest salient/distinct (polymorphic) to fight rubber-stamping. - **Beware emergent multi-agent failure and mis-specified objectives [O-5].** The Flash Crash: individually "correct" fast algorithms (one optimizing *volume only*) produced systemic collapse. Constrain objectives explicitly; add *system-level* circuit breakers, not just per-agent ones. - **Cranor (2008) is the direct precedent for a modern agentic HITL framework [O-9]:** keep the human out of the loop where you can safely automate; where a human must stay, engineer the interaction (delivery, comprehension, capability, motivation) so they can actually succeed. ### Annotated bibliography **[O-1] COSO / internal-control literature.

[study]** *Safe Reinforcement Learning via Shielding.* AAAI-18. — A correct-by-construction **shield** from a formal safety spec intercepts each action and overrides only those that would violate safety (preemptive or post-posed). *Relevance:* a verified shield that vetoes the agent — encode hard constraints (never delete prod, never send funds >X) enforced regardless of what the LLM "decides," including under injection. **[O-19] Mehmood, U., et al.

[study — extends O-17; author list lightly UNVERIFIED]** *The Black-Box Simplex Architecture for Runtime Assurance of Autonomous CPS.* NASA Formal Methods / arXiv:2102.12981. — Extends Simplex to opaque/neural controllers and even black-box safe controllers via a switching monitor. *Relevance:* confirms the runtime-assurance pattern survives when both actor and parts of the guard are opaque — wrap an LLM agent in a switching monitor with a "safe mode" (halt + escalate) on predicted breach. --- # Part V — The Human and the Loop Episode _The human side, and the design of a single oversight moment._ ## V.P — Cognition of advice, judgment & decision fatigue _The human-cognition side of HITL: how people receive advice, decide under pressure, and whether decisions degrade with fatigue. Contested results flagged explicitly._ ### Highlights - **Two opposite failure modes coexist.** Classic advice research shows **egocentric discounting** — humans *under*-weight good advice [P-2, P-3] — while the AI-advice literature shows both **algorithm appreciation** (over-crediting an "AI" label, [P-20]) and **algorithm aversion** (over-abandoning after one visible error, [P-21]). HITL must calibrate against *both* under- and over-reliance. - **Anchoring on the agent's suggestion is the central, most robust risk [P-9].** A suggested answer pulls the human's judgment toward it with insufficient adjustment, even when wrong; confirmation bias [P-11] then steers the evidence search toward confirming it. - **"Decide first, then reveal" is evidence-backed [P-4].** Independent pre-advice judgment yields better, less-deferential decisions than seeing the suggestion first. - **The most corrective advice is the most likely to be rejected (distance effect) [P-3].** Humans discount advice that diverges sharply from their prior — exactly the contrarian agent suggestions that may be most valuable; experts discount most. - **Trust is fragile and asymmetric [P-2, P-21].** Reputation forms fast and is lost more easily than gained; people drop algorithms faster than humans after identical errors. Error transparency, recovery, and letting users adjust outputs keep reliance from collapsing. - **Reliance is contaminated by irrelevant factors** — incidental mood [P-5] and the cost/effort of obtaining advice [P-6] move advice-weighting independently of quality. - **Expertise changes everything; both human and AI intuition have boundary conditions [P-7, P-8].** Experts pattern-match (RPD); intuition is trustworthy only in regular environments with good feedback — a two-condition test for whom to weight. - **Review quality is bounded by working memory [P-17].** Dense, poorly-presented agent output produces poor oversight regardless of intent — favor concise rationales, diffs, confidence cues. - **Decision fatigue should constrain HITL only weakly and provisionally.** The mechanism (**ego depletion**) **failed a 23-lab preregistered replication** (d≈0.04, [P-13], undercutting [P-12]); the iconic parole "hungry judge" study [P-14] is contested by an ordering confound [P-15] and a time-allocation artifact [P-16]. Treat "limit decisions per human" as a *testable heuristic*, not a law. - **Choice overload is similarly over-claimed** — the jam study [P-18] is famous but a 50-study meta-analysis found a mean effect near zero [P-19]. Don't assume "fewer AI options = better." - **The dual-process frame is sound but cite per-study carefully [P-9, P-10]** — System 1/2 and core biases hold, but some studies popularized in *Thinking, Fast and Slow* (priming) didn't replicate. - **Net stance:** build for *calibrated* reliance — force a provisional human judgment before revealing AI output (anti-anchoring), surface reasoning (counter discounting + confirmation bias), make errors/confidence transparent (manage fragile trust), minimize reviewer load, and treat fatigue/overload limits as hypotheses, not settled science. ### Annotated bibliography **[P-1] Bonaccio, S., & Dalal, R.

Organized around five necessary aspects + the choice-architecture layer that frames them. This cluster directly answers "what are the necessary aspects of the loop itself?"_ ### Highlights - **Interrupting the human is never free [Q-23, Q-24].** Even when output quality holds, interruptions raise stress, error, and anxiety; *timing* (defer to a task breakpoint) matters as much as content [Q-28]. Treat each oversight prompt as a priced action against an attention budget [Q-25, Q-26, Q-29]. - **Low-precision alerting destroys oversight [Q-30].** Humans reflexively dismiss *all* alerts — including critical ones — when precision is low. HITL prompts must be high-precision and role-targeted. The dominant real-world failure mode of "human in the loop." - **Humans systematically under-scrutinize confident automation [Q-17, Q-18].** A reviewer in the loop does not reliably catch errors by default — detection must be engineered. - **Detection-useful explanations are contrastive and demand-driven [Q-15, Q-16].** "Why / why-not" help most, and demand spikes when the system looks wrong; generic "show your work" framed to persuade can *increase* over-reliance. - **Uncertainty is a stronger detection signal than explanation [Q-20, Q-21]** — but only if calibrated and carefully framed; raw confidence is easily misread. Low confidence is a natural escalation trigger. - **Friction can backfire (sludge) or help (microboundaries / cognitive forcing) [Q-19, Q-33, Q-35].** Indiscriminate friction causes approval fatigue; targeted friction before irreversible actions reduces rubber-stamping. Audit friction against the stakes it gates [Q-34]. - **The default dominates the decision [Q-31, Q-32].** The safe/reversible option — never auto-approve-on-timeout — must be the default in any approval gate. - **Consequence preview is feedforward [Q-2, Q-3].** "What happens if I approve" is a named HCI principle (feedforward across the Gulf of Execution); reversibility/undo is a first-class safety affordance [Q-4]. Agents demonstrably propose irreversible harmful actions [Q-5], so pre-execution preview is necessary. - **The decision-point human is "out of the loop" [Q-10].** Being pulled in only at the moment of decision degrades situation awareness; the provenance/context trail restores SA [Q-9] and lets them reconstruct the situation (sensemaking) [Q-7, Q-8]. - **Provenance should be structured, not narrative [Q-12].** Separate data lineage from interaction history and decision rationale; PROV gives a ready schema (entities/activities/agents) for an auditable trail [Q-11, Q-13]. - **An approval prompt IS choice architecture — there is no neutral UI [Q-31].** The same levers (defaults, friction, framing) are weaponized as dark patterns; the dark-patterns corpus is a precise anti-pattern checklist (no confirmshaming "reject," false urgency, obstruction of deny/undo) [Q-36, Q-37, Q-38, Q-39]. - **Communicate stakes trustworthily, not persuasively [Q-6]** — the oversight moment's goal is genuine understanding, the inverse of manipulation. ### THE ANATOMY OF A WELL-DESIGNED LOOP EPISODE _An ordered checklist of the elements a single oversight moment should contain (each tagged with supporting sources).

Tags: [BOOK]/[EMPIRICAL]/[STANDARD]/[THEORY]/[REVIEW]._ ### Highlights - **Informate, don't just automate (Zuboff, [R-1]).** Agents should surface reasoning, evidence, and intermediate state to grow human understanding — not silently execute and hide the process. The root choice that determines whether HITL builds or erodes competence. - **Deskilling is the central failure mode HITL must prevent (Braverman [R-3], Bainbridge [R-6]).** Separating "conception" (judgment) from "execution" turns humans into rubber-stamps; "the human will catch it" fails once the human is deskilled into a passive monitor. - **Scaffolding + fading is the deskilling antidote and the template for *progressive autonomy* [R-9, R-10, R-8].** Calibrate support to the learner's zone, then *fade* it as competence grows — "without creating dependence." Cognitive apprenticeship's modeling→coaching→scaffolding→fading→exploration is a staircase for graduating autonomy and tapering oversight. - **Augment, don't replace (Autor [R-4], Brynjolfsson [R-5]).** Allocate by comparative advantage at the *task* level; the "Turing Trap" warns mimic-and-replace AI is the costly default to resist. - **Quality-estimation gating (MT QE [R-13], ISO 18587 [R-11]):** the agent emits a calibrated confidence/quality score; auto-proceed on high confidence, escalate low. A mature, operational confidence-routing mechanism. - **Risk-tiered review intensity (PE levels [R-12]):** match human effort to content risk/value — full review for high-stakes, light/sampled for low-stakes. - **Escalation tiers + queue routing (Gillespie [R-15]):** automated first-pass → front-line human → escalate hard/ambiguous cases up. Pair with transparency. - **Audit sampling of autonomous output (Grossman & Cormack [R-16]):** statistically sample and validate agent decisions against an expert/control set to certify quality; combine with active-learning loops. - **Second-reader / redundancy pattern (radiology CAD [R-17, R-18]):** run the agent as an independent parallel checker flagging candidates for adjudication — but tune flag volume, or it adds false positives and burden. - **Reviewer wellbeing is a first-class constraint (Roberts [R-14]).** High-volume HITL review harms reviewers; pacing/rotation/support must be designed in. The "human trains and backstops AI" loop is real and persistent. - **Joint optimization, not technical optimization (Trist & Bamforth [R-7]).** HITL is a *sociotechnical system* design problem; a technically superior agent that wrecks human roles is a net failure. - **Plans are situated — build for in-flight repair (Suchman [R-2]).** Favor continuous, cheap human repair over one-shot up-front approval; agency is reconfigured, not cleanly handed off. ### Annotated bibliography **[R-1] Zuboff, S.

(Parts III–V, added in a second round, overwhelmingly *reinforce* these from economics, law, safety science, manufacturing, finance, and education — see "What Parts III–V add" below.) That convergence is the strongest signal in the codex: these are not domain quirks but structural properties of putting a human in charge of an autonomous system. The recurring themes below are the load-bearing inputs to the framework. ### The ten recurring findings (each triangulated across ≥3 clusters) 1. **The reliability paradox — competence breeds complacency.** The more reliable the automation, the *less* the human monitors it, so the rare error is the one most likely to slip through. Stated by Bainbridge [E-7], measured by Parasuraman/Molloy/Singh [F-4, E-18], reaffirmed across autonomy levels [E-15, H-4], visible in AV crashes [H-16, H-17, H-18], and reproduced in coding agents where "safety contingent on developer oversight" decays under productivity pressure [A-18, A-21]. *Design consequence:* never treat a more capable agent as a reason for *less* oversight machinery — capability and complacency rise together. 2. **The exposure-vs-correction gap (the recognition bottleneck).** Oversight mechanisms reliably reduce the *occurrence* of bad actions but barely improve the human's ability to *catch* one once it surfaces. The cleanest evidence is [A-17] (plan-approval cut bad-action occurrence to 60–74% but intervention success stayed 9–26%); the mechanism is automation bias / commission errors [F-9, F-10, D-18] and the failure is *rationalization*, not inattention. *Design consequence:* gating *what the agent does* is easier and more effective than improving *what the human notices* — invest accordingly, and don't assume a gate makes the human a good detector. 3. **Nominal oversight ≠ meaningful control.** A human placed in the loop without authority, competence, awareness, or time becomes a *moral crumple zone* [F-19, D-16] / rubber stamp [D-4, D-14] / MABA-MABA trap [D-15] — absorbing blame while protecting the system. The constructive target is *meaningful human control* = **tracking + tracing** [C-20, D-13] and Billings' "informed, involved, in command" [E-21]. *Design consequence:* every oversight point must give the human real authority and the context to use it, or it is theater. 4. **Reversibility beats confirmation.** Confirmation dialogs habituate users into reflexive click-through and don't prevent errors; undo is the superior safety net [G-14, G-13, G-15]. Modern agents implement this as checkpointing/rewind [A-4] — but it has a hard boundary at the shell (Bash side-effects aren't tracked [A-4]) and false-alarm-prone confirmations actively corrode trust [F-17]. *Design consequence:* make agent actions reversible by default; reserve blocking confirmation for the genuinely irreversible — and know precisely what you cannot undo. 5. **The out-of-the-loop / handoff problem.** Pulling the human out of the loop degrades the *comprehension* (not just the data) needed to take over [E-12, E-13, H-3], and abrupt handoff to a disengaged human at the worst moment fails — re-engagement takes 1.5–3.5+ s and longer for competence [H-19], as AF447 [H-7] and AV takeover studies show. Today's models are *themselves* weak at mid-task steering/cancellation [A-19, A-16]. *Design consequence:* handoffs must be anticipatory, gradual, and context-rich; for time-critical failures the human fallback may not be viable, so don't architect safety around it. 6. **Autonomy is a multi-dimensional dial, not a switch.** Decide *which stage* (acquire → analyze → decide → act) and *what level* (suggest → act-with-approval → act-then-notify → act-silently) independently [E-4, E-6]; automate perception/analysis more freely than *action*, where over-trust and lost authority bite hardest. Mature agents implement this as permission modes + risk-tiering [A-2, A-5, A-6, A-13], and governance says oversight intensity should scale to autonomy/stakes [D-6]. *Design consequence:* gate by reversibility × blast radius × stakes, not uniformly; make stepping *down* to lower autonomy easy [H-6]. 7. **Trust must be calibrated — and explanations can decalibrate it.** Both over-trust (misuse) and under-trust (disuse) are failures [F-1, F-2, E-16]; the disposition to over-trust *labeled-AI* advice is a baseline risk [C-16]. Critically, explanations/rationales tend to *increase acceptance regardless of correctness* [F-20, C-17] — transparency aimed at empowering the overseer can instead disarm them. *Design consequence:* surface capability, uncertainty, and *verifiable* evidence (not just persuasive rationale); design explanations to support checking, not agreeing. 8. **The signal economy: every interruption is a tax, and false alarms are the worst tax.** False-alarm-prone systems corrode both compliance and reliance [F-17] and drive alert fatigue — clinicians override 49–96% of alerts [H-10], TMI flooded operators with 100+ alarms [H-20]. The portable discipline: an alarm must demand a *specific* response, and the interruptive rate must be capped [H-21]; you cannot fix fatigue by muting the noisiest category [H-11]. *Design consequence:* treat interruptions as a scarce budget; most signals should be passive/logged, reserving blocking interventions for high-severity, high-precision cases. 9. **Deskilling erodes the very expertise oversight depends on.** Heavy automation atrophies skill — especially higher-order judgment [E-22, H-9, E-7] — and the human-feedback literature shows you need competent humans to evaluate at all [B-1, B-8]. A reviewer who never does the task cannot meaningfully review the agent. *Design consequence:* build in deliberate human-only practice / engagement, or accept that the oversight claim hollows out over time. 10. **Structural friction beats exhortation; sandboxes beat per-action gates.** Telling people to "stay vigilant" does not work [F-7, E-17]; *cognitive forcing functions* (decide before seeing the AI's answer; mandatory deliberation) measurably reduce over-reliance [F-21, C-18] though users dislike them. At the system level, the practitioner consensus is to move the safety boundary into the *environment* — sandboxes, no-network containers, scoped credentials, budget caps [A-23, A-1] — and to recognize the *lethal trifecta* (private data + untrusted content + external comms) as the condition under which an agent must not run unsupervised [A-23]. *Design consequence:* prefer architectural and forcing-function controls over asking the human to be more careful. ### The hard tensions the framework must resolve (not eliminate) - **Autonomy vs. oversight capability.** Every increment of autonomy that makes the agent more useful also degrades the human's situation awareness and takeover ability [E-13, H-4]. There is no setting that maximizes both; the framework must choose *per action class*, not globally — Shneiderman's 2-D HCAI insists the two are independent axes and the goal is high-high [G-4], but the empirics [E-15] show that is hard-won, not free. - **Friction vs. usability.** The interventions that most reduce over-reliance are the ones users most dislike [F-21, C-18, A-17]; the interventions users love (one-click approve, YOLO mode) are the ones that produce rubber-stamping. The framework must spend friction deliberately where stakes justify it, not uniformly. - **Explanation vs. over-trust.** Users need intelligibility to oversee [G-17, G-11], yet explanations increase uncritical acceptance [F-20]. The resolution is *verification-oriented* transparency (evidence the human can independently check) over *persuasion-oriented* rationale. - **Scaling oversight vs. preserving the human.** AI-assisted oversight (debate, amplification, RLAIF, AI supervisors) is the only way to oversee superhuman-scale work [C-3→C-13, A-15, B-20], but each step that lets AI help the human evaluate also *removes* the human a little, relocating risk into the assisting AI's blind spots [B-20, C-8]. Net team performance can even go *down* [C-19]. The framework must track where genuine human judgment still lives. - **Mandated vs. effective oversight.** Law and standards increasingly *require* oversight [D-1, D-2, D-5] while the evidence says humans routinely can't deliver it [D-14, D-17→D-25]. Compliance and safety are not the same goal; designing for the checkbox can actively produce a crumple zone. The framework should treat oversight as a claim to be *validated*, per Green [D-14]. ### Seed design principles for the framework (provisional) These fall out of the findings above and will be developed into the actionable framework: 1. **Gate by consequence, not uniformly** — reversibility × blast-radius × stakes determines whether an action is auto-run, notify-after, approve-before, or forbidden [A-6, E-6, D-6]. 2. **Default to reversible; confirm only the irreversible** — checkpoint/undo as the primary net; blocking confirmation as the rare exception [G-14, A-4]. 3. **Make state, intent, and evidence legible — for verification, not persuasion** [G-17, F-20]. 4. **Budget interruptions; make every alert demand a defined action** [H-21, F-17]. 5. **Engineer the environment, not just the dialog** — sandbox, scope credentials, break the lethal trifecta; forcing functions over exhortation [A-23, F-21]. 6. **Design the handoff, not just the autonomy** — anticipatory, gradual, context-rich; assume re-engagement latency; keep the human warm where takeover must be fast [H-19, E-13]. 7. **Keep the human competent** — deliberate engagement/practice to resist deskilling and complacency [E-22, F-7]. 8. **Give oversight real teeth** — authority + competence + time + traceability, or don't claim it [D-4, C-20]; and *validate* that it actually works [D-14, A-17]. 9. **Scale span deliberately** — there is a hard ceiling on how many agents one human can oversee [H-22]; plan oversight capacity as a finite, budgeted resource. 10. **Treat the model's steerability as a constraint, not a given** — interruptibility and mid-task correction are unsolved model capabilities [A-19], so design within their limits. ### What Parts III–V add (delegation, mechanisms, the episode) The nine second-round clusters largely *reinforce* the ten findings above — itself strong corroboration, since they come from economics, law, safety science, manufacturing, finance, and education rather than AI. The genuinely new contributions: 11. **Oversight is costly monitoring — so monitor the exceptions (principal–agent theory).** A human delegating to an agent is a textbook principal–agent relationship [J-1, J-2]; agency cost (monitoring + bonding + residual loss) never reaches zero, so the goal is *minimizing total cost*, not maximizing control. "Management by exception" [K-1] and the informativeness principle [J-7] agree: log the trace, review the deviations, accept a residual loss. 12. **The real lever is residual control rights, not an exhaustive rulebook (incomplete contracts).** You can't specify correct behavior for every state [J-8, J-9]; control *is* holding the override / selective-intervention right (halt, revoke, substitute) for the unforeseen — and some duties are *non-delegable* by law [J-15], a hard floor under "a human must decide." 13. **Brief by intent, not by steps (mission command).** Commander's intent + mission orders ("results, not how") [K-7] and a small set of pre-authorized rules of engagement [K-12] out-perform micromanagement under uncertainty — and autonomy must be paired with shared context [K-10]. 14. **Decouple tightly-coupled agent pipelines (normal accident theory).** Interactive complexity + tight coupling make accidents "normal" [L-10]; the structural fix is to *insert slack* — human checkpoints, reversibility, rate limits, circuit breakers [O-6, O-7]. Redundancy can *backfire* [L-11]; more checkers ≠ more safety. 15. **Watch for drift and normalization of deviance.** Oversight standards erode silently as "we got away with it" repeats [L-15, L-16]; track the *trend* in oversight bypasses, not just incidents. Deference to expertise [L-7] says authority should migrate to whoever has the local knowledge. 16. **Capability-removal beats policy — cross-domain consensus.** Poka-yoke's hierarchy (prevention > detection > vigilance) [N-7], lockout > tagout [N-17], and least-privilege / capabilities [O-10, O-11] all say what the agentic-security literature does: make bad actions *impossible*, don't merely discourage them; a bypassable denylist is not a boundary [A-14]. The confused-deputy problem *is* prompt injection [O-11, O-12]. 17. **Two-party approval and verified shields are mature, portable gates.** Four-eyes / maker-checker and the two-person rule [O-1, N-15] (proposer ≠ approver), and runtime shields / Simplex [O-17, O-18] (a verified monitor that vetoes the agent, even under injection), are battle-tested machinery — and Cranor (2008) [O-9] is a *direct prior HITL framework* this codex generalizes. 18. **The loop episode is a designable unit (and usually under-designed).** A single oversight moment must supply request clarity, **consequence + reversibility preview** (feedforward [Q-3]), **provenance** ("how did this get to me" [Q-7, Q-11]), **detection affordances** (why/why-not + calibrated uncertainty, framed to *check* not *sell* [Q-16, Q-20, F-20]), and **a respected attention budget** — with bias-safe choice architecture and no dark patterns [Q-31, Q-36]. Cross-domain evidence converges that *gates only work when meaningfully attended* (Ontario checklist [N-12], ISMP double-checks [N-16], alert fatigue [H-10, Q-30]). See the full anatomy in §V.Q. 19. **Under-reliance is a failure mode too — and decision-fatigue evidence is shaky.** Classic advice research shows humans *under*-weight good advice (egocentric discounting [P-2]) even as automation-bias research shows over-reliance, so calibration must guard both directions [P-20, P-21]. And "limit decisions per human" rests on contested ground: ego depletion failed a 23-lab replication [P-13] and the "hungry judge" effect is disputed [P-15, P-16]. Treat it as a testable heuristic, not a law. 20. **Informate, don't just automate; fade scaffolding to fight deskilling.** Agents should surface reasoning/evidence to grow human understanding [R-1], and scaffolding-with-fading [R-9, R-10] is a concrete model for *progressive autonomy* that preserves the competence oversight depends on. Mature workflow precedents — quality-estimation gating [R-13], escalation tiers [R-15], audit sampling [R-16] — are ready patterns to borrow. ## Open questions & gaps - **Closing the recognition bottleneck.** [A-17] shows gates don't help humans *catch* errors. What actually improves *detection* (vs. prevention)? Forcing functions [F-21] help reliance but detection-specific interventions for agentic settings are largely unstudied. - **Calibrated transparency.** We know explanations can increase over-trust [F-20]; we lack tested patterns for *verification-oriented* disclosure that raises detection without raising blind acceptance — especially for long chain-of-thought / multi-step agent traces. - **Oversight of agent fleets / multi-agent systems.** Supervisory-span limits are documented for UAVs [H-22]; the analog for one human overseeing many concurrent LLM agents (and agents overseeing agents [A-15, C-22]) is barely measured. - **Validated oversight metrics.** Green [D-14] demands evidence that oversight works, but there is no standard instrument for measuring *effective* (vs. nominal) human control of an agent. What would a "meaningful control" conformance test look like? - **Reversibility at the shell / real world.** Checkpointing covers structured edits but not Bash side-effects [A-4], and many agent actions (sends, payments, deletes) are irreversible by nature. How much of an agent's action space can be made *genuinely* undoable, and how should the irreducibly-irreversible remainder be governed? - **Deskilling under pervasive agent use.** The aviation evidence [E-22, H-9] predicts judgment decay; the longitudinal effect on developers/knowledge workers using agents daily is unmeasured. - **Model steerability as the bottleneck.** [A-19] shows interruption/cancellation/re-planning are weak model capabilities. How much HITL design is currently limited by the *model* rather than the *interface*, and which patterns degrade gracefully when steerability is poor? - **Trust dynamics over long horizons.** Most trust studies are short-session [F-3]; how reliance calibrates (or miscalibrates) over months of living with an agent — incl. recovery after a visible failure — is open. - **Cross-cultural / individual variation.** Complacency potential is an individual difference [F-6] and trust has dispositional/cultural layers [F-3]; per-user adaptive friction is proposed but untested in agentic tools. - **Measuring meaningful control.** [C-20, D-13] define control as *tracking + tracing*, but no operational test exists for whether an agent's behavior actually tracks the human's reasons and traces to an informed human — the conformance test governance [D-14] implicitly demands. - **The loop-episode evidence gap.** The anatomy in §V.Q is assembled from adjacent fields (security warnings, clinical alerts, sensemaking, provenance, choice architecture); few components are tested *in agentic-LLM settings* — especially provenance displays and consequence-feedforward for multi-step agent plans, and which detection affordances actually raise catch-rate [A-17]. - **Capability-removal vs. usefulness.** Poka-yoke / least-privilege say "make it impossible" [N-7, O-10], but over-constraining throttles useful autonomy [K-14]; the trade-off curve for agents is uncharted. - **Does AI-assisted oversight net help?** Human–AI teams often underperform the better of either alone [C-19]; whether AI supervisors / debate / runtime shields actually raise *effective* human oversight of agents (vs. relocating risk into the assisting system [B-20, C-8]) is largely untested in real agentic settings. --- ## Status & provenance - **Assembled:** 2026-06-22, in **two rounds** of parallel research agents — 8 clusters for Parts I–II, then 9 for Parts III–V (**17 clusters, ~366 reference entries**). Each agent was instructed to retrieve real sources, distinguish empirical from opinion, record successes *and* documented failures, and flag any unverified citation. - **Verification posture:** the large majority of entries were confirmed against publisher pages, DOIs, arXiv IDs, or authoritative indexes. Items the agents could not machine-verify (paywalls/ 403s, JS-rendered legal pages) or flagged for a pinpoint check are marked **UNVERIFIED** or "cross-confirmed via secondary sources" inline — incl.

These overlaps are themselves a finding: the same handful of results anchor trust, automation theory, scalable oversight, governance, teaming, and the loop episode — and the new delegation/mechanism clusters (J/K/N/O) corroborate them from outside AI.
