… Windows job
The new macOS job immediately caught a real portability bug:
try_flush_send_buffer_shrinks_after_full_drain assumed a single
non-blocking write drains a unix socket pair's buffer, which holds on
Linux but not on macOS (~8 KiB default vs Linux's much larger default).
Explicitly grow SO_SNDBUF/SO_RCVBUF past the test payload on both ends so
the assumption holds on every platform.
The Windows job never had a chance: server/client/transport/session::conn
build socket ownership handoff on std::os::unix::io::{AsRawFd, IntoRawFd,
FromRawFd} throughout, not just behind the tls feature, so even
--no-default-features fails with ~30 E0599 errors. Making that portable
to AsRawSocket/RawSocket is a real feature, not a CI tweak, so drop the
job rather than ship a permanently red (or permanently continue-on-error,
i.e. pointless) check.

This job fails before compiling any tests because rustc does not accept undefined as a value for -Zsanitizer; the official sanitizer documentation lists the supported values and UBSan is not among them. Since this job runs on every push and pull request without continue-on-error, it adds a permanently failing CI check rather than undefined-behavior coverage.

The workspace includes fuzz, whose direct libfuzzer-sys dependency declares (MIT OR Apache-2.0) AND NCSA; because the allow-list ends without NCSA, the new licenses matrix job rejects the current dependency graph on every run. Add NCSA or explicitly exclude the fuzz package if it is intentionally outside this check.

On a tag push, the preceding step deliberately excludes the current tag and selects PREV_TAG, but this command discards that value and asks abi-baseline.sh to compare HEAD. The script resolves its baseline with git describe --tags --abbrev=0 HEAD, which is the newly pushed tag itself, so it builds that same commit as both the baseline and current artifact and cannot detect a release ABI break.

The --jobs option runs mutant tests concurrently, so four workers here can execute the repository's integration suite at the same time. Those tests bind shared fixed ports such as 19665–19668, and the trailing --test-threads=2 only limits threads within each individual test harness, not the separate mutant workers; resulting address-in-use failures are therefore recorded as mutants being caught and can substantially inflate the mutation score. Use one mutant worker or exclude/externally serialize the socket integration tests.

…utants ports) - abi-check.yml: the baseline-detection step computed PREV_TAG but never wired it into the actual comparison, which passed the literal string "HEAD" to abi-baseline.sh compare. On a tag push, HEAD's nearest tag is the tag just pushed, so it would diff that release against itself and could never catch a real ABI break. Output and pass the resolved tag. - deny.toml / fuzz/Cargo.toml / supply-chain.yml: cargo-deny resolves the graph rooted at whichever manifest it's pointed at, not the whole workspace, since the root Cargo.toml is a package, not a virtual workspace manifest. A root-only run never saw the fuzz crate's own dependencies at all, silently missing libfuzzer-sys's NCSA-licensed component. Run cargo-deny against both Cargo.toml and fuzz/Cargo.toml, which surfaced two more real gaps once fuzz was actually covered: librtmp2-fuzz had no `license` field, and unrestricted `[graph] targets` pulled in UEFI-only transitive deps (LGPL-2.1-or-later `r-efi`) that are never actually compiled for any target this repo builds. Added the missing license, scoped `targets` to the real CI platforms, allowed NCSA, and allowed the fuzz crate's unversioned path dependency on its parent crate via `allow-wildcard-paths`. - mutants.yml: dropped `-j 4`. The crate's integration tests bind fixed ports (19661-19668), so concurrent mutant workers would collide on the same port and get recorded as "caught" by an unrelated bind failure rather than by the mutated logic, inflating the mutation score.

Addressed the Codex review findings:
Generated by Claude Code |
scripts/abi-baseline.sh compare does `cargo clean --release` followed by a full `cargo build --release --all-features` twice (once for the baseline tag, once for the current commit), which took well over 40 minutes against this crate's dependency tree in practice - two stuck runs on PR #271 had to be cancelled. CLAUDE.md already documents this as a manual pre-release step, not a per-commit one, so give it a cadence that matches: push to main, workflow_dispatch, and a weekly schedule, in its own workflow file (abi-dump-check.yml) with a 60-minute timeout so a slow run can no longer run unbounded. cargo-semver-checks stays on every push/PR in abi-check.yml since it only takes ~30-40s.

…ilures, socket test) - abi-dump-check.yml: select the baseline tag by resolved commit instead of ref-name string. The old exclusion only matched when GITHUB_REF was itself a tag ref (a tag push); on a push-to-main or workflow_dispatch run where HEAD happens to already be tagged, it could pick that same tag as the baseline and diff HEAD against itself, silently missing a real ABI break. - miri.yml / mutants.yml: drop continue-on-error. Both jobs only run on a weekly schedule or workflow_dispatch - never gating a PR - so masking a real failure as green serves no purpose and just hides the exact signal these jobs exist to surface. The if: always() artifact upload is unaffected. - src/client/mod.rs: the SO_SNDBUF/SO_RCVBUF fix from the earlier macOS fix never checked setsockopt's return value or the effective buffer size afterward. A sandboxed runner with a lower net.core.wmem_max/ kern.ipc.maxsockbuf ceiling could silently clamp the request below what the test needs, reproducing the exact class of bug being fixed just on a different platform. Assert each setsockopt call succeeds and confirm the effective SO_SNDBUF via getsockopt before relying on a single-write full drain.

Summary
Existing CI already covers unit/E2E tests, ASan, overflow checks, 5 libfuzzer
targets, interop scripts,
cargo-semver-checks, and benchmarks. This adds theremaining high-value gaps so more of the surface is actually exercised:
deny.toml+ Supply Chain workflow —cargo-denychecks foradvisories, license allow-listing, banned/duplicate deps, and source
registries, run against both
Cargo.tomlandfuzz/Cargo.toml(cargo-denyresolves the graph rooted at whichever manifest it's pointed at, not the
whole workspace, so a root-only run silently missed the fuzz crate's own
dependencies, e.g. libfuzzer-sys's NCSA-licensed component). All 8
combinations pass today.
cargo-llvm-covover unit + E2E tests, with anlcov artifact, an HTML report artifact, a
$GITHUB_STEP_SUMMARYsummary,and a best-effort Codecov upload (
continue-on-error, no token required tomerge). 428 unit tests + all E2E tests pass under instrumentation, 86.76%
line coverage today.

(19661-19668), so concurrent workers would collide and get recorded as
falsely "caught".
