# Deterministic, cross-platform seeded sampling for rollup metadata.
# rand_chacha is explicitly portable (ChaCha8Rng gives the same sequence
# from the same seed on Linux, macOS, and Windows) — unlike SmallRng,
# which picks the fastest underlying generator per platform and is NOT
# stable across them. Determinism is load-bearing for snapshot tests
# and agent-cacheable outputs; performance is irrelevant here because
# we draw at most K samples per group, not per line.
#
# Keep default-features enabled: the `alloc` feature (on by default) is
# what gates `IndexedRandom::choose_multiple`, and we deliberately skip
# pulling in rand_core for thread-local RNGs we don't use.
#
# Pinned to 0.9, not 0.10, on purpose. Revisit only when one of the
# "when to migrate" conditions below is true:
#   - A security advisory lands against 0.9.x (RUSTSEC-2026-0097 is
#     already fixed in 0.9.3 and does not affect our seeded use anyway).
#   - The 0.9 line stops receiving patch releases.
#   - We need something 0.10 adds (unlikely — our surface is two calls).
# Why not now:
#   - rand 0.10 only promises stream stability for StdRng, not for
#     ChaCha8Rng (now a re-export from the `chacha20` crate under a
#     `chacha` feature). The sampler was also renamed `choose_multiple`
#     → `sample` in the same release. Either of those could shift the
#     exact draw without any compile error, silently re-baselining every
#     insta snapshot touching rollup metadata and invalidating agent
#     caches keyed on output. The determinism contract above is the
#     whole reason we use this crate, so drift here is a regression
#     even when it "still works".
#   - rand and rand_chacha must be bumped together (separate PRs hit
#     two-copies-of-rand_core and fail to compile — see closed PRs #33
#     and #38). Dependabot is grouped + 0.10-major-ignored accordingly
#     in .github/dependabot.yml.
