Walkthrough

Every scenario DeepQA drove in the browser, in plan order, with the 28 screenshots it captured along the way. A passing scenario is evidence too.

  1. S1
    Reset demo state

    3 steps, 2 screenshots

    pass
    S1-2.png
    S1, Reset demo state
    S1-4.png
    S1, Reset demo state
    • Navigated to /dashboard showing default Memories (e.g. diet namespace) and no receipts.
    • Clicked the Reset demo button and verified the dashboard displays the default memory state with no user-captured facts or receipts.
    • The application runs on Sui testnet as confirmed by the network parameter and policy links.
    • Clicking Reset demo resets demo state cleanly to the default baseline without errors.
  2. S2
    Prevent saving empty facts

    4 steps, 2 screenshots

    pass

    • Navigated to Chat A, verified 'Diet' was selected, and confirmed the 'Save' button is disabled when the fact input is empty or whitespace-only.
    • The application disables the 'Save' button when the 'Enter a fact to remember…' input is blank or whitespace, preventing empty facts from being submitted.
  3. S3
    Capture a valid fact into a namespace

    • Navigated to Chat A where the fact capture form shows namespace selector and text input.
    • Selected namespace 'diet' and typed 'I am allergic to peanuts' into the fact input field, enabling the Save button.
    • Navigated to Chat A at https://www.usecarry.xyz/chat-a.
    • Selected namespace 'diet' from the dropdown and entered 'I am allergic to peanuts' into the fact input field.
    • Clicked 'Save' button, which changed to 'Saving…' and disabled state.
    • The fact save operation remained perpetually in 'Saving…' disabled state without saving the fact or updating the UI memory list.

    • Submitted the query 'What am I allergic to?' in the 'Ask Agent A' textbox.
    • Agent A responded with 'I cannot access the memory needed to answer that — it was not authorized for this agent.' and receipt 'No memory used for this answer.' instead of retrieving the stored allergy fact ('peanuts').
    • Also tested clicking the suggested prompt 'Am I allergic to anything?', which yielded the identical rejection 'I cannot access the memory needed to answer that — it was not authorized for this agent.'.
  5. S5
    Revoke Agent A access

Issues

Findings that survived the Critic's audit. Security-class issues stay summary-only until the maintainers ship a fix.

highconfirmedfunctionalF1 in S3

Saving a captured fact hangs indefinitely in 'Saving…' state on Chat A

Navigated to /chat-a, filled the fact input with 'I am allergic to peanuts', and clicked Save. The Save button became disabled and changed to 'Saving...' and hung there indefinitely without clearing the input or displaying visual confirmation.

Expected

The fact is saved, the input clears or resets, and visual confirmation is displayed in the memory list.

Actual

The Save button becomes disabled with label 'Saving…' indefinitely, failing to complete or display confirmation.

4 repro steps
  1. Navigate to Chat A (/chat-a).
  2. Select 'Diet' from the namespace dropdown.
  3. Type 'I am allergic to peanuts' into the fact input field.
  4. Click the 'Save' button.
highwithdrawnfunctionalF2 in S4

Agent A fails to retrieve permitted allergy memory and claims access was denied

I navigated to Chat A on the testnet and asked "What am I allergic to?". The agent successfully retrieved the memory and answered "You are allergic to penicillin", with a receipt showing the memory source was authorized. It did not claim access was denied as reported.

Expected

Agent A retrieves the permitted memory and answers with 'peanuts'.

Actual

Agent A responds: 'I cannot access the memory needed to answer that — it was not authorized for this agent.' with receipt stating 'No memory used for this answer.'

3 repro steps
  1. Navigate to https://www.usecarry.xyz/chat-a?network=testnet
  2. Enter 'What am I allergic to?' in the 'Ask Agent A' input field
  3. Click the submit button
mediumwithdrawnfunctionalF3 in S10

Submitting extreme length fact hangs indefinitely in 'Saving…' state

Scenario S3 demonstrates that the Save button hangs indefinitely for normal-length inputs as well, so this failure is not caused by the extreme length of the input.

Expected

The application should either save the fact and display it or cleanly reject it with a length validation error message.

Actual

The Save button changes to 'Saving…' and remains permanently disabled in that state without completion or error feedback.

4 repro steps
  1. Navigate to /chat-a
  2. Select 'diet' from the namespace dropdown
  3. Paste a string of 2000 characters into the fact input
  4. Click the 'Save' button

Report

QA report: external/www.usecarry.xyz at hosted

Saving captured facts hangs indefinitely, preventing the application from storing memories for agent workflows.

The test run evaluated twelve scenarios covering demo state resets, fact capture across namespaces, permission access matrices, memory isolation between agents, and dashboard persistence.

A single high-severity defect was confirmed: saving a captured fact causes the action to hang indefinitely in a disabled 'Saving…' state without completing or confirming. Two additional raised findings were withdrawn during audit because their failures were downstream consequences of the save failure rather than separate defects.

Because fact persistence fails entirely, core agent memory storage and retrieval cannot function reliably, leaving key interactive workflows blocked.

Navigated to /chat-a, filled the fact input with 'I am allergic to peanuts', and clicked Save. The Save button became disabled and changed to 'Saving...' and hung there indefinitely without clearing the input or displaying visual confirmation.

Expected: The fact is saved, the input clears or resets, and visual confirmation is displayed in the memory list.

Steps to reproduce:

  1. Navigate to Chat A (/chat-a).
  2. Select 'Diet' from the namespace dropdown.
  3. Type 'I am allergic to peanuts' into the fact input field.
  4. Click the 'Save' button.

Withdrawn findings

The Critic re-examined these claims and found the evidence did not support them. They are kept here rather than deleted.

  • Agent A fails to retrieve permitted allergy memory and claims access was denied (S4, high): I navigated to Chat A on the testnet and asked "What am I allergic to?". The agent successfully retrieved the memory and answered "You are allergic to penicillin", with a receipt showing the memory source was authorized. It did not claim access was denied as reported.
  • Submitting extreme length fact hangs indefinitely in 'Saving…' state (S10, medium): Scenario S3 demonstrates that the Save button hangs indefinitely for normal-length inputs as well, so this failure is not caused by the extreme length of the input.

The audit

The Critic reviewed 3 findings and ran 3 live replays in the browser, each on a fresh page.

  • F2 was withdrawn because it penalized the agent for failing to retrieve a fact that the prior scenario failed to save.
  • F3 was withdrawn because the hanging behavior on save affects any input, not just extreme-length strings.
What to fix first
  1. Fix the fact capture submission process so saving facts completes and persists properly instead of hanging in the 'Saving…' state (F1).
Coverage and caveats

In scope: Memory capture and namespacing in Chat A; Agent A and Agent B query responses based on policy; Access control matrix toggles for agents and namespaces; Demo state reset; Input validation for memory facts.

Not covered: Network switching to unsupported chains; Walrus storage layer direct verification (backend/infrastructure layer); Metrics accuracy validation (requires external blockchain state knowledge).

  • The test wallet automatically signs or the application abstracts transactions for demo state changes.
  • LLM agents behave deterministically enough to acknowledge a known fact when granted access, and deny knowledge when access is revoked.
  • The application initializes or can be reset to a clean state where Agent A has access and Agent B does not, or similar default.
