Injection is runtime data, so 'compile-time' overstates it. A type system can taint-track — mark untrusted input, block it from a privileged sink. Valuable, but that's enforcement, not detection.

Network-layer enforcement is right. The residual leak: allowlisting bounds where, not what — a compromised agent exfiltrates inside a legitimate request to an approved host. Covert channels move up to content.

Selective storage worries me — discernment is the model deciding what to drop, and you can't recover what it discarded. Storing everything and making retrieval selective fails safer.

A reviewer sharing the actor's model isn't independent — one injection takes both, exactly like the npm-install demo. What held for me was a deterministic allowlist no prompt talks past.

Reconciling intent has a bootstrap problem: it's inferred from the same model you're constraining, so it rationalizes. Side-effect gates — spend, irreversible writes — can't be talked around.

Inspectable state shows what the agent believed, not why it diverged. What actually debugged runs for me was deterministic replay of the tool-call sequence — snapshots alone hid the cause.

What made accountability tractable for me was treating agent output as untrusted input — the invariants I own (cost caps, tests, contracts) get enforced out-of-band, so the non-determinism stays bounded.
