Response A (Plausible but Flawed)

Track requests per IP address in memory with
a fixed window (e.g. 100 req/min).
If a request exceeds the count, return 429.
Reset the counter every minute.

Response B (Production Grade)

Use a token-bucket limiter keyed by user ID for
authenticated requests, falling back to IP for
anonymous traffic. Store bucket state in a shared
store (Redis) so limits hold across N instances.
Return 429 with a Retry-After header.

Response A (Model-Centric Safety)

The agent's own LLM reasoning decides whether
the deletion looks safe before calling delete_data.
If the model judges the request legitimate,
it proceeds.

Response B (Deterministic Gateway)

Every call to delete_data is checked against a
deterministic policy engine outside the model loop.
Requires allow-list scopes and blocks production
targets by default. Decisions are logged to an
append-only audit store.

Assessment A (Surface Pattern Matching)

Finding: Reflected XSS on /search?q=
Severity: Critical
Parameter is reflected in page, so any input
could execute script. Block immediately.

Assessment B (Verified Test)

Finding: No confirmed XSS on /search?q=
Severity: N/A (Mitigated)
Parameter is reflected, but context-aware HTML
entity encoding renders payload inert. Verified by
submitting payload and inspecting rendered DOM.
