# cargo-deny configuration (Phase 1.4).
#
# Runs in CI on every PR via `cargo deny check` in `mnemo/`. Three
# checks matter here:
#   1. `advisories` — cross-references the RustSec advisory DB and
#      fails on any unpatched vulnerability affecting a dep in the
#      lockfile.
#   2. `licenses` — allowlist of OSI-approved licenses compatible
#      with the Apache-2.0 the mnemo crate itself is published under.
#      Anything unlisted requires an explicit `exceptions` entry.
#   3. `bans` — currently informational (`multiple-versions = "warn"`)
#      to catch transitive duplication without blocking merges while
#      we enumerate the necessary skip set. Follow-up PR will
#      tighten to `deny` once CI has surfaced the real exception
#      list.
#
# Run locally with:
#     cd mnemo && cargo deny check
#
# For just one check:
#     cargo deny check advisories
#     cargo deny check licenses
#     cargo deny check bans

# ---------------------------------------------------------------------
# Graph configuration — what crates the checks apply to.
# ---------------------------------------------------------------------

[graph]
# Empty `targets` means "check all crates for all target triples the
# lockfile references." Since mnemo compiles on Linux/macOS/Windows
# x86_64+aarch64, restricting to a single target would hide license /
# advisory hits on platform-specific transitives (e.g. `windows-sys`
# on Windows only).
targets = []
all-features = false
no-default-features = false

[output]
# Group violations by feature depth; keeps the diagnostic readable
# on the multi-page transitive graph typical of a Rust crate.

# Advisory DB — RustSec vulnerability + yanked-crate check.

# yanked from crates.io. `warn` first so we notice; upgrade to
# `deny` once we've picked up a clean baseline.
yanked = "warn"
# Time-boxed / justified exceptions to the advisory check. Every
# entry must carry a `reason` — a future worker reading this file
# should be able to tell why the ignore was granted without leaving
# the config.
ignore = [
    # `paste 1.0.15` — dtolnay archived the repo (RUSTSEC-2024-0436,
    # "unmaintained"). NOT a vulnerability. It is pulled transitively
    # by `rmp` / `rmp-serde` (our MessagePack layer) which have no
    # migration path today. The advisory itself suggests `pastey` as
    # a drop-in fork; that migration lives in `rmp`, not here. Revisit
    # when `rmp-serde` ships a release that swaps to `pastey`.

[licenses]
version = 2
# Kept minimal — the mnemo dep graph in practice only ships crates
# under Apache-2.0, MIT, BSD-3-Clause, and Unicode-3.0 (the newer
# SPDX variant `unicode-ident` uses). Apache-2.0 WITH LLVM-exception
# covers the `rustix` family. Adding an unused allow is not a security
# hole but it's noise — cargo-deny prints an "unmatched license
# allowance" warning for each, and drift in the allowlist becomes
# hard to notice. Extend this list only when a new dep actually
# ships under something not already here.
