# ── tidal-crate lint posture (single source of truth) ──────────────────────
# The four tidal crates (tidaldb / tidal-net / tidal-server / tidalctl) carry an
# IDENTICAL, stricter-than-workspace [lints] posture and deliberately DO NOT
# inherit `[workspace.lints]` (`lints.workspace = false` is the Cargo default).
# Rationale: this is the embedded recommendation DB plus its transport, server,
# and CLI — a correctness-critical, mostly self-contained subsystem held to a
# higher bar (`unsafe_code = forbid`, `clippy::all = deny`, `unwrap_used = deny`).
# `unwrap_used = "deny"` is kept per-crate rather than promoted into
# `[workspace.lints]` because the workspace also hosts the example/consumer
# crates under `applications/`, which are not held to the engine's bar.
# Keeping the block per-crate turns an accidental divergence into an
# intentional, documented one.
# Keep these four blocks BYTE-IDENTICAL when changing one.
