premium_cont_00098 | Debug drill 3248: map validation. | Focus: ipcz routing. | When debugging map validation, log message flags, interface_id, message name, request_id, responder map state, and whether validator or deserialization rejected the message. Concept: A Mojo map is serialized as two arrays, keys and values. Validation checks that both arrays are valid and have the same length. |
premium_cont_00099 | Risk of misunderstanding BlobDataItem, case 2705. | Risk: false exploit claim or missed bug. Do not conflate route authority, schema validity, and response correlation. Ground truth: BlobDataItem is browser-side blob storage metadata. For memory research, verify object layout and allocation site rather than assuming fields are attacker-controlled. | |
premium_cont_00100 | Verification checklist 596 for ConfigureProxyIfNecessary. | Target: Chrome M105 RCA style. | Check exact Chromium tag, generated binding output, method ordinal, flags, request_id handling, validator table, and handle ownership. Concept: ConfigureProxyIfNecessary lazily creates the generated proxy. It initializes InterfaceEndpointClient and then constructs the Proxy with endpoint_client(). |
