Problem

extension.ts:621, inside the storage-export command, maps each AuditEntry returned from the audit logger into the ReportGenerator's AuditEntry shape and assigns the original entry to details via:

const auditEntries = auditLogger.getAll().map(e => ({
    timestamp: new Date(),
    type: 'audit',
    details: e as unknown as Record<string, unknown>
}));

The as unknown as Record<string, unknown> is the "I give up" cast: it strips the compiler's view of the value down to unknown and then re-asserts it as a record. There's no real structural check in either direction. It's also unnecessary here — AuditEntry is a plain interface whose every field is a primitive, string union, or any, so a fresh object literal copied from it is naturally assignable to Record<string, unknown> with a single narrowing cast.

Fix

details: { ...e } as Record<string, unknown>

The cast target is now a fresh object literal rather than the original AuditEntry reference. Two side benefits beyond removing the double cast:

• If AuditEntry later grows a nested object field that can't satisfy Record<string, unknown>, the single cast will surface that as a real type error to investigate, rather than the previous unknown shape laundering it silently.
• The details field no longer aliases the live AuditEntry stored in the logger's internal array, so callers further downstream can't mutate the logger's state through the report payload.

Test

The agent-os-vscode package's existing test script wraps the VS Code integration runner; this is a shape-only change in a .map callback and the produced object is structurally identical at runtime. No behavioural change on either path.
