molluskandClaude Opus 4.8 465c7ba2b0 Add cargo-deny supply-chain policy (deny.toml)
Supersede bare cargo-audit with an enforceable four-part policy, validated
against the current tree with cargo-deny 0.19.9 (advisories/bans/licenses/
sources all pass):

- advisories: deny vulnerabilities + yanked; ignore the two *unmaintained*
  warnings (paste RUSTSEC-2024-0436, audiopus_sys RUSTSEC-2026-0150) with
  rationale. Both are transitive and pinned via Cargo.lock, so a future
  malicious release can't reach us until a deliberate cargo update.
- sources: trust only crates.io; deny unknown registries and git sources
  (core anti-hijack control).
- bans: deny wildcard version reqs; warn on duplicate versions.
- licenses: permissive allow-list covering the current graph.

Mark peerspeak publish = false (it's an application, not a published
library): blocks accidental cargo publish and lets [licenses.private]
skip the missing-license check.

# cargo-deny policy for peerspeak
#
# Supersedes a bare `cargo audit` run. Enforce with:
# cargo install cargo-deny --locked
# cargo deny check
#
# In CI, run `cargo deny check` on a locked tree so the pinned, vetted
# versions in Cargo.lock are what actually get audited.
# ---------------------------------------------------------------------------
# Advisories: RustSec database. Vulnerabilities and yanked crates are denied
# by default. The two `ignore` entries below are *unmaintained* warnings only
# (no known exploit); they are deep transitive deps we cannot remove. Pinning
# them via Cargo.lock is our real protection — a future malicious release does
# not reach us until we deliberately `cargo update`, so each update is a review
# checkpoint. Revisit these if either advisory is upgraded to a vulnerability.
# ---------------------------------------------------------------------------
