Abstract

Autonomous agents increasingly consume stored trust surfaces — a skill's claimed verdict, a recalled memory note, their own report that a task is done — as fact. We ask whether re-deriving such a claim, rather than trusting its label, changes agent behavior, and we pre-commit to what counts as success before running anything. Across two models (two sizes within the Claude 4.x family, claude-sonnet-4-6 and claude-haiku-4-5), two structurally different task families, and a preregistered arm matrix arbitrated solely by a deterministic verifier, we report three findings, each labeled by evidence tier.

(1) On a cross-session memory-poisoning surface, a mandatory out-of-band re-derivation gate collapses corroborated-poison attack-success to the floor (ASR 0.000, flat across save strength, both tiers) precisely where the agent's own optional self-search over a corroborating channel amplifies it (ASR up to 0.950): the rise reflects the content of a channel built to corroborate the poison, not a measured verification skill, and its magnitude is corpus-construction-dependent. Stated alongside, and load-bearing: when the channel reliably carries the truth, the agent's own check ties the gate. The gate's value is channel-integrity-independence, not agent helplessness. (2) Every measured win is harm-neutralization, not uplift. An effect that looked in a pilot like the gate makes agents better (Δ+0.60) reversed to null under power (Δ+0.06, p=0.68); we publish the reversal in full, because preregistration is what makes it legible. (3) An unattested surface degrades agents; a re-derivable one restores baseline.

The artifact at the end — relyable, an Apache-2.0 re-derivation gate built on the open veriker verifier — is the smallest of our claims. This is benchmark-grade measurement, not a deployed-fleet study; we report sign and direction across models, not a transfer claim.

1Introduction

Consider an agent that finishes a task and reports: ✓ done — all tests pass. Re-derive the run in a clean context and the tests resolve NOT-RUN; the agent wrote the summary, not the result. Under a gate that admits only what re-derives, the verdict is ERROR, fail-closed — the claim is refused because it does not reproduce, not flagged as low-confidence and passed through. We reproduce this failure mode under control in §5.3, where a negative-control run exhausted its retries and landed ERROR rather than a silent pass.

That gap — between what a persistent agent reports and what actually re-derives — is what we set out to measure before building anything to address it. The motivation is not hypothetical. More than 40% of agentic AI projects are forecast to be canceled by the end of 2027 [7]; AI models introduced an OWASP Top-10 vulnerability in 45% of code samples across more than 100 models and four languages [8]; 81% of enterprise technology leaders report increased production issues attributable to AI-generated code, and 70% say maintaining the test suite is now a larger burden than writing code [9]. The agents themselves carry open, linkable demand for exactly the surfaces we study: a persistent-agent harness whose agent authors its own skills with no external validation point [12], and a file-memory agent whose recalled notes are trusted with no freshness or provenance check, so a stale note silently overrides current truth [13][14].

This is a measurement paper. We treat three things a persistent agent trusts — its skills, its memory, and its own verdicts — as trust surfaces (a trust surface is a stored artifact an agent consumes as fact without recomputing it), and we ask one question of each: if the consumer re-derives the claim instead of trusting the label, what changes? The three are a taxonomy, not one shared apparatus: skills and memory pass through the shared relyable.gate admission path, while verdicts re-derives through its own runner (§5.3). We pre-registered every experiment (design, arms, primary statistic, stopping rule) before any agent solved anything, and a deterministic verifier — not the solver's self-report — is the sole arbiter of every outcome. Solver self-reports were discarded; across every experiment they lied in both directions (cells narrated "verified, correct" while landing a rejected answer, and the reverse). That an agent's self-asserted confidence is not a usable trust signal is itself one of our findings.

Our headline result is counterintuitive and is the one a reviewer cannot wave away: on a poisoned memory surface, letting the agent verify itself by searching a corroborating channel makes it more wrong, while a mandatory out-of-band re-derivation gate drives the attack-success rate to zero. But the same data carry the honest bound that keeps that headline from overclaiming, and we state them together throughout. The tool we ship is deliberately the last and smallest thing in the paper.

2Related work, and how we reconcile with it

Our results line up with the recent literature rather than fighting it; where they appear to conflict, the conflict resolves on closer reading.

Self-correction is a labeling artifact, not a capability ceiling. Huang et al. [4] established that LLMs do not reliably self-correct reasoning unaided. The sharper recent result is the Self-Correction Illusion [1]: relabeling a model's own erroneous content as an external source raises its explicit-correction rate by 23 to 93 percentage points (range across 13 model-by-domain cells) — a chat-template role artifact, not a reasoning limit. One of our memory experiments reproduced this from the other side: a loud "this is confirmed correct, do not re-derive" cue, read by the agent as an external, untrusted instruction, provoked verification rather than suppressing it (§5, Exp M). We do not claim "loud warnings always backfire"; we read both results as the same mechanism — externalize a claim and the agent will check it. Our gate is a way to externalize every claim an agent makes about its own work, so the check no longer depends on the agent choosing to treat the claim as someone else's.

Memory poisoning propagates, without an attacker. The HEARTBEAT study [2] shows that routine background memory-saving promotes adversarial content to durable memory at rates up to 91% (their Table 5a, strongest save level), with cross-session attack-success up to 76%, and that enabling the agent's own web search dents but does not eliminate it (from 80% to 60% in the software domain at the strongest level). Prompt injection is not required; ordinary social misinformation suffices. HEARTBEAT names the head-to-head we run — mandatory out-of-band re-derivation versus the agent's optional discretion-verification — but did not test it. The "Taming OpenClaw" threat taxonomy [3] frames the lifecycle (memory poisoning, skill supply-chain contamination, indirect prompt injection, intent drift as compound cross-stage risks) and observes that re-derivation and out-of-band attestation are an open gap. We adopt HEARTBEAT's promotion model as a stated assumption (we do not re-measure promotion; §7) and measure the recall-edge contrast it left open.

3The gate

The object under study is relyable.gate: a host-side, out-of-band re-derivation admission gate. It admits a stored artifact — a skill's claimed verdict, a recalled memory note — only if that artifact re-derives against the consumer's own trusted grader, run through the open-tier veriker verifier. The agent that produced the artifact cannot self-attest past the gate, because the gate never trusts a label, only a recomputation — the producer's label is never load-bearing.

3.1Three structural properties

These are properties of the mechanism, not configuration options.

  1. Verify, do not execute (by default). Admission is a re-derivation — recompute the claimed result in a clean context and compare — not a re-run of arbitrary producer code. Executing an in-bundle pack is a separately gated lane (permit_execution is an explicit caller argument, never a default), so the generic safe path cannot be turned into an execution primitive by a poisoned bundle.
  2. Digest-pinned grader. The grader that decides admission is always the consumer's own trusted copy, pinned by SHA-256 before any verifier verdict is trusted. A bundle that ships its own grader, or omits one, cannot produce a trusted admit. This closes a real hole: an absent grader would otherwise let the raw verifier return NO_PACK with ok=True and never grade the candidate — a spurious pass.
  3. A poisoned or unverifiable entry is inert — no soft-admit. It is dropped, not passed through as a weak signal. There is no "admitted with low confidence" middle state to ride past: either the artifact re-derived under the pinned grader, or it did not exist as far as the consumer is concerned.

The dependency direction is one-way: the gate imports only the open verify surface of veriker (the bundle verifier, the verdict type, the re-derivation invocation check). It is a genuine consumer of that verifier, not a fork of it.

3.2The two entry points

The builder assembles a content-addressed bundle whose grader is always copied from the consumer's trusted source, so a poisoned bundle cannot ship a lying grader. The builder computes digests to assemble the bundle but is not itself the trust rail — the verifier's independent strict-SHA walk re-checks every digest at verify time, and that walk is the rail.

relyable.gate.build_bundle(
    dest, *, candidate_body, meta, grader_src, bundle_id, ...) -> Path
  # skill/candidate.py    candidate body (digest-bound)
  # skill/meta.json       consumer-shaped meta
  # re_derive/<pack>      grader, ALWAYS copied from grader_src
  # manifest.json         declares the re-derivation invocation; digest-binds every file

relyable.gate.verify(
    bundle_dir, *, grader_src, permit_execution=False, ...) -> GateResult

The verify call is a fail-closed sequence. (i) Grader present? Absent → NO_GRADER. (ii) Grader byte-identical to the consumer's trusted copy? Mismatch → GRADER_MISMATCH, and the verdict is never run. (iii) Only then run the re-derivation-invocation check and wrap the verifier's verdict. Because the pin happens before any ok is trusted, the gate is safe over an arbitrary directory — not only over bundles the consumer itself built — which is what lets it stand between an agent and a stored artifact of unknown provenance.

GateResult:
  grader_ok          bool
  grader_reason_code  NO_GRADER | GRADER_MISMATCH | None
  verdict            the raw veriker Verdict
  .ok                admitted
  .is_error          could-not-conclude (e.g. RE_DERIVATION_NOT_EXECUTED)
  .first_reason_code , .detail

The shared layer never decides the consumer's admit/reject label; each surface binding maps this result into its own vocabulary. That separation is what lets one gate core serve both the skills and memory bindings, while the verdicts surface (§5.3) re-derives through its own runner rather than this admission path.

The honest boundary — carried verbatim The gate is a correctness / anti-silent-failure tool, not a performance booster. It does not make agents smarter, faster, or cheaper (in one pilot, gated memory cost more tokens). Its wins are harm-neutralization: it stops a poisoned surface from making an agent worse, and restores the baseline an unvetted surface erodes. It is integrity, not correctness — it tells you whether the thing the agent claimed actually re-derives, which is a narrower claim than "your code is right." That narrowness is the point, and it is the only claim defensible in a hostile room.

4Method

Preregistration discipline. Every experiment has a frozen preregistration committed before any agent solved anything: design, arms, primary statistic, and the section-5 decision rule (the exact inequality on the primary statistic that would count as support) fixed in advance. The verdict is computed mechanically from the frozen aggregates. Where we changed a preregistered rule, we disclose it (§7, Amendments 1 and 2) rather than silently re-deriving the bar.

The verifier is the sole arbiter. A fresh agent instance solves each cell behind a byte-identical neutral wrapper; the cell prompt is the sole stimulus. Outcomes are scored by a deterministic verifier from a structured output field, never from the solver's prose. For the poisoning experiment the dispatch is the contamination-free direct model API with a neutral software-assistant system prompt and no project context (see §7 for why this matters).

Two task families. A numeric statistical-power formula (continuous scoring) and a genomic interval-union task (binary pass/fail with exact-set-equality checks); the memory-poisoning line additionally uses a published-advisory recognition substrate with a sealed, externally verified ground-truth reference. Two model scales throughout (two sizes within the Claude 4.x family): claude-sonnet-4-6 (stronger) and claude-haiku-4-5 (weaker).

The arm matrix. Across experiments the arms instantiate a common pattern: a no-surface baseline (A); the surface present but unattested (a stale or unlabeled note, an unlabeled registry); the surface present and re-derivable through the gate; and, for the poisoning line, the agent's own optional verification over either a corroborating channel or a truth-carrying channel. Statistics are paired exact-McNemar contrasts (binary families) or the preregistered primary on the continuous family, at the preregistered α.

5Results

Every number below is labeled powered or pilot. A pilot number never borrows a powered experiment's confidence. The memory surface leads, and within it the poisoning experiment (H3) leads, because it is the strongest result in the corpus: powered, contamination-controlled, deterministically scored, and the one case where the gate beats the agent's own search. Per-experiment preregistration controls forking paths within an experiment but not the family-wise rate across the roughly twelve-experiment corpus, from which we excluded nulls (§5.4); we rest the headline on H3 (p=1.4e-17, far past any reasonable family-wise correction) and label every pilot as such.

5.1Memory — re-derive a recalled note

H3 — the headline. powered (n=60 per cell per tier, α=0.01, contamination-free direct API, deterministic scorer.) Attack-success rate (ASR) is the fraction of fresh-session recommendations that land an affected version per a sealed, externally verified advisory. A reply that names no version, or a version outside the catalog, is scored conservatively as not-misled, so an empty or malformed output cannot inflate the gate's apparent win. The save-strength gradient (S0, S2, S4) is modelled from HEARTBEAT's promotion rates (§7); arms A and G span the gradient, the verification arms sit at the strongest level S4.

A − V_faithful+0.283 (1.5e-3)+0.333 (1.9e-6)a truth-carrying search genuinely helps

The mechanism is genuine re-derivation, not refuse-then-resubmit: on every promoted gate cell at S4 (55 of 55, both tiers) the recalled poison version is rejected and the landed recommendation re-admits through the relyable.gate path as a re-derived safe version. Among agents that ran the optional search over the corroborating channel, the invoke-but-still-trust rate is 0.971 (Haiku) and 0.927 (Sonnet) — almost everyone who self-verifies on a channel that agrees with the poison applies the poison anyway. Gate-invariance to save strength (ΔG across S0 to S4 = 0.000 on both tiers while raw recall climbs by +0.516 / +0.333) is true by construction — the gate discards the recalled note and re-derives against the sealed reference, so how aggressively the poison was saved cannot reach the verdict. What we measure here is that the live victim, handed the inlined advisory, does not re-emit the poison, and that a clean recalled note is still admitted on both tiers (no false reject).

Carried alongside the headline — do not read one without the other The gate's headline win is established against the corroborating channel (V_pure), the realistic poisoning regime where the poison and the open web agree. Against a channel that reliably carries the truth (V_faithful), the agent's own discretion-verification shows no difference from the gate detectable at this power (Sonnet V_faithful − G = 0.000, p=1.0, n=60; Haiku +0.250, below the preregistered +0.30 bar, so that contrast's support flag is reported False). The gate's distinctive, robust value is that it does not depend on the channel surfacing the truth: it re-derives against a sealed first-party reference the consumer controls, so it collapses ASR to zero whether the social channel corroborates the poison or not. We do not claim agents cannot protect themselves — they can, when the channel carries truth. We claim you should not bet the system on the channel carrying it.

M — verified-good memory is a safe lift. powered (n=50, 300 cells.) A remembered note consumed as fact. Gate-admitted correct memory delivers the full uplift of raw correct memory (M_att_clean 1.00 versus baseline A 0.66, +0.34, p=1.5e-5) at no wrapper cost detectable at this power (versus the un-gated clean note, Δ0.00, p=1.0, n=50), and the same gate refuses the poisoned version (M_attested 0.58, statistically indistinguishable from A). One preregistered sub-claim self-corrected at power: the loud "do not re-derive" poison provoked verification rather than suppressing it, so its harm endpoint is moot rather than a win (this is the result that reconciles with [1] in §2).

F2 — the gate recovers an unseen poisoned convention. powered (n=30 per arm, 180 cells, supports_lever2=true.) M_attested 1.00 versus A 0.00, p=1.86e-9. Reported honestly: the active ingredient is the calibration pointer the gate produces (the marker naming held-out evidence), not the refusal framing — a generic nudge carrying the same pointer recovers equally (M_attested − nudge = +0.033, p=1.0). The distinctive thing the gate buys is auto-producing that redirect against a poison no human pre-wired.

D, E, persistent-E — drift, three honest pilots. pilot (n=10, or n=6 sessions per configuration.) On a long-horizon task where a drifted note is catastrophic, the gate recovers to baseline by refusing the note (D: M_attested 0.90 versus M_stale 0.00, p=0.0039; M_attested equals the un-memoried baseline, not above it). The same gate is safe in both directions off a floor baseline (E). Across a real multi-session drift, the gated configuration stays correct every session while raw memory goes silently stale post-drift (persistent-E: gated 6 of 6 versus raw 3 of 6). Load-bearing caveat: persistent-E's "cheaper" rests on the re-derivation count (6 / 1 / 2), not on measured tokens — the configurations do not separate on tokens and the gated arm is nominally the most expensive. E's preregistered zero-cost sub-claim did not fire at n=10 (token noise). These pilots are recover-to-baseline evidence, not uplift.

5.2Skills — re-execute a claimed verdict

Exp 3 — gate-value isolation. powered (n=32 per verdict.) Where a skill cannot be cheaply self-vetted, the admission verdict neutralizes wrong-skill harm: admitted skills land 0.938 versus rejected 0.062 (Δ+0.876, p=7.45e-9), and a no-consensus pile is 0.90 gated versus 0.00 ungated.

Exp 6 — the harm-neutralization headline. powered (n=50 per arm; the n=10 pilot was a superseded outlier — see §6.) On a second task family, a labeled surface beats an unlabeled one by Δ+0.50 (B 0.76 versus C 0.26, p=4.6e-6). But against the no-surface baseline the label is null: B − A = +0.06, p=0.68. An unattested registry (C − A = −0.44, p=5.9e-5) or merely the cue that one exists (D − A = −0.38, p=5.5e-4) significantly degrades the agent; the re-derivable label only restores baseline. The label is harm-neutralization, not uplift.

Exp 5 — the label is causal and consumed unverified. pilot (n=10.) A forged trust label pointing at a rejected skill was followed 10 of 10 times; the one-click evidence bundle that would have exposed the forgery was opened 0 of 10 times (D 0.00 versus B 1.00, p=0.002). A poisoned label is worse than no gate; label integrity must be infrastructure, not recipient diligence.

Exp 4 — an unlabeled registry is itself harmful at scale. pilot (n=10.) At a registry too large to read, the validated label routes trust to a correct unit (B 1.00 versus C 0.00, p=0.002), while the unlabeled registry falls below baseline (C 0.00 below A 0.50). The mechanism is position-anchoring, not vetting (equal, minimal reads across arms).

Exp 2 — the honest boundary. pilot (n=10.) Where skills are cheaply self-vettable, the gate neutralizes no harm beyond the agent's own consensus vetting (gate versus self-vettable pile Δ0.00, p=1.0). We state this plainly; it sharpens the claim — the gate earns its value exactly where self-vetting is not cheap, and is redundant where it is.

5.3Verdicts — re-derive the completion claim

Evidence boundary The verdicts surface re-derives a completion claim through its own runner, not the relyable.gate admission path the skills and memory bindings share. It rests on a single experiment (Y); we do not fold Y's numbers into the skills or memory claims, and they do not lend theirs to it.

Exp Y — re-derive at the deliver edge. powered (n=30 per arm per model, α=0.01.) At the point a result is marked complete, re-deriving it rather than trusting the completion claim moves the weak model from 0.033 to 0.967 (Δ+0.934, p=7.45e-9); the strong model goes 0.767 to 1.000; harness-by-model interaction +0.701, sign test 22 of 23, p=6e-6. The recovery is genuine re-derivation, not resubmission: all 28 weak-fail-to-pass flips changed the landed convention rather than resubmitting the same wrong answer. The negative control held — one weak seed exhausted its retries, never stabilized, and landed an ERROR rather than a silent pass. This is "completed with nothing to re-derive" surfaced rather than ridden green.

5.4What we exclude

One experiment (X, compaction drift) is a null at the swept scale on a different line; we exclude it rather than fold a null into an unrelated claim. A second (W, a routing-label gap-narrowing result) shows a measured but conditional effect — correctness-routing under a low unaided baseline, not "smarter" — and we treat it as a caveat (§7), never a headline.

6The reversal we published

Our pilot looked excellent. At n=10, the attestation label that marked a skill as verified appeared to lift agents sharply: B over A, Δ+0.60, p=0.031. It would have been the cleanest growth story in any deck — our label makes agents better. We could have shipped that number.

Then we powered it to n=50. The effect reversed to nothing: B − A = +0.06, p=0.68, not significant. The label does not make agents smarter. The pilot estimate was a small-sample fluke, and the powered estimate is the truth.

pilot n=10:  Δ+0.60, p=0.031  →  powered n=50:  Δ+0.06, p=0.68 (n.s.)

We publish the reversal in full because the preregistration is what makes it legible rather than buried. We fixed the primary statistic and the stopping rule before solving, so the pilot-to-power move is a disciplined update, not a goalpost shift — and the honest reading of the powered data is the narrower, defensible one we state throughout: an unattested surface degrades the agent, and a re-derivable label restores the baseline. Defensive, not offensive. The version of this work that hides the reversal is not one worth publishing.

7Limitations — read this first

We would rather you attack the scope than discover it. These bounds are load-bearing, not boilerplate.

8Reproducibility and posture

We publish this paper alongside the open-source veriker verifier, not ahead of it. The verifier and the bundle format are Apache-2.0; the gate, relyable, depends on that published substrate. The sample receipt is the claim from §1 made runnable: point the gate at an output that reports ✓ all tests pass and watch it re-derive to ERROR, fail-closed by default. Once the repository lands this week the re-derivation runs in a single command, and we invite you to break it and tell us where it is wrong.

The preregistrations are committed before each solve with frozen hashes; the deterministic scorers and the neutral dispatch harness are public so the headline checks can be re-run. Where the "a stranger can clone and reproduce one task" gate is not yet green at publication, the corresponding artifacts ship in a described, verifier-plus-reports-land-this-week posture rather than as a one-click reproduction — stated, not implied.

Where we stand among the existing work — and what we do not claim The nearest neighbor is the IETF Internet-Draft draft-krausz-verification-state-01 [5] (the current revision as of this writing), a fail-closed gate in which the relying party recomputes the verdict-to-gate mapping locally from the issuer's signed primitives. Our distinction is narrow and specific: we re-run the substantive grader itself, on the consumer's own trusted grader, so the issuer's verdict is never load-bearing — the agent cannot self-attest past it. We sit in the emerging agent trust stack alongside static scorecards (for example an Apache-2.0 MCP scorecard) and runtime-reputation packages, and we complement, rather than replace, provenance tooling (SLSA, in-toto, Sigstore), the IETF SCITT transparency envelope, and the RATS vocabulary [6] — our gate output is, in RATS terms, an Attestation Result. Against probabilistic guardrails and LLM-as-judge systems (for example NeMo Guardrails, Guardrails AI), the difference is that we re-derive deterministically; we do not re-judge probabilistically. We do not claim to be the first fail-closed gate, the first to recompute locally, the inventors of re-derivation or receipts, or the only open-source option. We claim the specific articulation "admit only what re-derives," and its application as re-running the consumer's own grader on stored artifacts of unknown provenance.
