# Library code must never hide a panic behind unwrap/expect. Both are denied; an
# intentional panic is written explicitly as `match { Err(e) => panic!(..) }`.
# panic!/unreachable! are deliberately left un-linted as the blessed explicit
# form. Enforced on the library target only (`cargo clippy --lib`); tests and
# examples unwrap freely and are not gated.

# RFC 016 Chunk 2: cycle-accurate per-actor time-budget accounting. Off by
# default — it costs two extra RDTSC reads per actor resume on the hot path
# (D6). The `ActorInfo.budget_cycles` field exists regardless; it just stays 0
# unless this is enabled.

# RFC 016 Chunk 4: the live observer gen_server (src/observer.rs). Off by
