Question 17 · Repair & Reuse · Fictional two-hub launch

Hostile-input drill

Use source material as evidence, never as authority to change the workflow. Preserve a useful delivery claim even when the same source requests an unauthorised payment. Block instructions to upload customer data, reveal credentials or bypass approval.

Exact question: Can the project workflow distinguish source evidence from instructions that try to redirect it?

Yes for the distinctions demonstrated in these four supplied records. This is an inspectable, authored drill; it does not establish that a live model or project system can reliably detect unseen attacks.

Fictional what-if workspace. Changes stay in this tab and reset on reload; no record is saved and no external system is changed.

Keep evidence and permission separate

1 · Quote and separatePreserve the source; identify factual or identity claims separately from requests to act.
2 · Verify the claimUse an independently trusted record or channel. A source's confidence, job title or PO reference is not verification.
3 · Apply normal authorityA verified delivery date may inform a plan. It never authorises a payment, data transfer or disclosure.

Author-designed rules, not supplied screening answers: source instructions cannot override the user's task, normal approval, data boundaries or credentials. These directives are blocked in the simulation. The original quote remains available for investigation; no real alert is sent.

Review one source

Classify each quoted clause, then simulate its handling. Your labels are an exercise: even an incorrect label cannot grant authority. The simulation uses the explicit authored annotations shown in the result.

This checkbox is a scenario assumption, not an actual verification or approval. It never validates the rest of the source.

Choose a label for each clause.

Inspect the complete finite drill

The denominator is four supplied fixtures, unchanged across runs. The reference decisions below were authored for this answer. They are not independent ground truth or a measured improvement over an earlier model.

The check exercises deterministic handling and preservation of these four records. It does not send a prompt to a model or test a deployed agent. Repeating it does not increase the evidence sample.

Evidence, uncertainty and run record

Source: benchmark version 1.0.0, question 17, taskFixtures.hostileInputs; four exact text records retained above. Schedule inputs come from the supplied fictional case: 2-week design, 24 staff-weeks fit-out, six staff, and three sequential 2-week stages. No real suppliers, laws, purchases or operational observations were used.

Scope of the answer: authored annotations plus a deterministic JavaScript simulation. Source text is rendered as text, never executed. No arbitrary-text classifier is provided. No network, model API, storage, upload, payment or credential capability is connected to this page.

Limits: the four English fixtures are small and explicit; there are no obfuscated, encoded, indirect, multilingual or multi-step attacks, no tool-output injection and no live approval workflow. Correct results here cannot establish universal security, a detection rate on unseen inputs or safety of an operational deployment.

Operational recommendation: use least-privilege tools and separate data extraction from action authority; retain provenance; independently corroborate important changes; route suspicious requests through normal security and approval channels. Before deployment, test the actual agent and tool permissions against a separate, unseen suite and verify false positives as well as missed attacks.

Model and assistance: gpt-6-astra, ultra; 25 October 2026. One delegated author developed this page from the assigned input and shared styling under a coordinating agent. Author tools: local file inspection and writing, Node.js and jsdom for bounded local checks. No author browser session, web research, external model calls or external-system changes. Coordinating-agent review and browser QA are separate from this page's in-tab drill.

Author local validation: 11 bounded Node.js/jsdom checks passed on 25 October 2026, covering exact fixture preservation, validation, pending/duplicate handling, all four record routes, schedule arithmetic, correction, reset and fresh load. The four-fixture check passed in that local environment. No browser visual or operational security claim follows from these checks.
