Summary

v3.4.2 "Countersign": the RustyNES core in RetroArch loads on Apple Silicon Macs again.

Symptom (maintainer): RetroArch on a Mac froze and dropped back to the shell when it loaded RustyNES from the Online Updater, for at least the last couple of releases. The desktop app was fine.

Cause: libretro's rust-apple.yml template runs $STRIP -S on the core after linking. On arm64 the linker has already ad-hoc signed the dylib, and the image's strip (osxcross, on Linux) rewrites it without re-signing. macOS kills any process that loads arm64 code with a broken signature. The buildbot's core of 2026-10-20 had 101 of 538 page hashes mismatched; gambatte and snes9x from the same server (built natively on a Mac) had 0.

Fix: libretro-build-osx-arm64 sets STRIP_CORE_LIB: "0"; libretro_buildbot_audit pins it (mutation: deleting the line fails the test). Intel Macs, the desktop app, iOS and tvOS were not affected.

Verification

• On the maintainer's Mac (M5 Max, macOS 27.0.1): the buildbot's own arm64 core with only its signature repaired (ad-hoc, 0 of 538 mismatched) loads in RetroArch; the unrepaired file killed it.
• On libretro's own buildbot: pipeline 125851 built this branch; its unstripped arm64 core verifies (538 pages, 0 mismatched, linker-signed), and the maintainer loaded that exact build in RetroArch on the same Mac.
• Security: RUSTSEC-2026-0382 / -0381 fixed by rustls-webpki 0.103.16 and webpki-roots 1.0.10; the 0.26.11 shim and basic-toml (RUSTSEC-2026-0374) recorded as documented exceptions, the first guarded by dependency_floor_audit.
• Upstream report: rust-apple.yml / rust-osx.yml: post-link strip breaks the arm64 macOS code signature, so RetroArch is killed loading Rust cores libretro/libretro-super#2154.
• Release audits: release_anchor_audit 18, release_state_prose_audit 9, release_notes_render_audit 4, libretro_info_audit 6, libretro_buildbot_audit 2; markdownlint and clippy clean.

Release

No emulation, app, format or RTL change (epoch 5, protocol 9). The MiSTer bitstreams are v3.4.1's, attached byte for byte under v3.4.2 names. RetroArch users get the fix from the nightly buildbot of main and must re-download the core.

Note

Medium Risk
Touches TLS trust roots for netplay and RetroAchievements plus libretro macOS packaging; emulation logic is unchanged, but TLS and how the arm64 core is built affect real user sessions.

Overview
v3.4.2 "Countersign" is a patch release: emulation, apps, and save/movie/netplay formats stay on v3.4.1 (epoch 5, protocol 9).

The headline fix is RetroArch on Apple Silicon. The libretro buildbot job libretro-build-osx-arm64 now sets STRIP_CORE_LIB: "0" so the post-link strip no longer breaks the linker’s ad-hoc arm64 code signature (which had been killing RetroArch at core load). libretro_buildbot_audit locks that variable in the job’s variables: block; x86_64 still strips as before.

Security housekeeping bumps rustls-webpki to 0.103.16 and webpki-roots 1.x to 1.0.10 for netplay and RetroAchievements TLS. dependency_floor_audit fails the build if webpki-roots 1.x drops below 1.0.10, backing documented RUSTSEC-2026-0381 and basic-toml (RUSTSEC-2026-0374) ignores in deny.toml / .cargo/audit.toml.

Everything else is the 3.4.2 version sweep (workspace, Android/iOS, hosted RA_USER_AGENT, libretro .info, changelog and release notes).

📝 Walkthrough

RustyNES v3.4.2 disables post-link stripping for macOS arm64 libretro builds, adds CI and dependency audits, updates version identifiers, and records the release.

Changes: RustyNES v3.4.2 Release

Layer / File(s)	Summary
Arm64 build setting and audit .gitlab-ci.yml, crates/rustynes-test-harness/tests/libretro_buildbot_audit.rs, to-dos/plans/v3.4.2-plan.md, docs/agents/libretro.md	The macOS arm64 build job sets STRIP_CORE_LIB to "0". An integration audit checks this setting and verifies parsing of the arm64 and x64 jobs. Supporting documentation records the signature failure and verification requirements.
Dependency advisory and version audits .cargo/audit.toml, deny.toml, crates/rustynes-test-harness/tests/dependency_floor_audit.rs, CHANGELOG.md	Advisory exceptions are documented for webpki-roots and basic-toml. Tests enforce the webpki-roots version floor and accepted shim.
Version identifiers Cargo.toml, crates/rustynes-cosim/Cargo.toml, crates/rustynes-libretro/rustynes_libretro.info, android/app/build.gradle.kts, ios/project.yml, services/hosted/package.json, services/hosted/wrangler.jsonc	Workspace, crate, application, hosted-service, and libretro metadata now identify version 3.4.2.
Release records and documentation .github/release-notes/v3.4.2.md, AGENTS.md, ARCHITECTURE.md, OVERVIEW.md, README.md, ROADMAP.md, SECURITY.md, SUPPORT.md, VERSION-PLAN.md, docs/STATUS.md, to-dos/ROADMAP.md	Release notes, project guidance, and release histories identify v3.4.2 as current and describe the Apple Silicon RetroArch loading fix.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: ⚪ Minimal · up to c6033

No actionable merge-blocking risk remains from the reviewed change.

Security architecture risk: 🔵 Low · up to c6033

The Apple Silicon build change preserves code signatures rather than weakening macOS enforcement. Its scope is narrow, but the inherited build steps and final distributed library have not been independently verified at the reviewed revision.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The signing-policy delta directly affects the macOS arm64 libretro library and RetroArch installations that obtain its replacement. The inspected job change does not extend builder authority or add signing credentials; its purpose is preserving executable integrity within the existing distribution path.

Trust Boundaries and Controls

• inferred — The repository supplies configuration to an external Apple build template, and macOS subsequently enforces the resulting image's signature. Preserving an ad-hoc signature is an integrity measure, not evidence of authenticated publisher identity. External post-processing and publication controls remain outside the verified source coverage; the PR does not introduce that trust dependency.

Resilience and Maintainability Implications

• observed — The new advisory-wide webpki-roots exception relies on a separate compensating lockfile test. That test rejects a missing 1.x package, versions below 1.0.10, and unexpected non-1.x versions; a second test requires the separate cosim lockfile to remain free of webpki-roots.

Hardening Proposals

• proposed — As follow-on hardening, verify signature integrity on the exact arm64 library selected for publication and retain its digest and build revision. This would complement the configuration audit and manual loading evidence without treating the existing external verification gap as a newly introduced vulnerability.

Explanation

Docstring coverage is 84.62% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 13 functions across 3 files. (3 skipped: 3 unsupported.)

Full details: Docs-As-Spec Sync

Explanation

PASS: The reviewed PR range changes no files under crates/rustynes-cpu, crates/rustynes-ppu, crates/rustynes-apu, or crates/rustynes-mappers. Therefore, it introduces no observable chip-behavior change that requires a matching docs/<subsystem>.md update.

Full details: No Unwrap/Expect/Panic On Untrusted Input

Explanation

The PR adds panic-like code only in two integration-test files under crates/rustynes-test-harness/tests/. These checks read fixed repository files (Cargo.lock and .gitlab-ci.yml) or deliberately constructed test fragments. They do not process ROM, save-state, movie, network, netplay, or user-supplied path data. No production Rust code changed.

Full details: Safety Comment On New Unsafe Blocks

Explanation

The pull request adds two Rust test files. The PR diff contains no added unsafe keyword, and neither changed Rust file at the head contains an unsafe fn or unsafe { block. The SAFETY-comment requirement is therefore not applicable.

Full details: Changelog Entry For User-Visible Changes

Explanation

The PR fixes a user-visible Apple Silicon RetroArch loading bug. The CHANGELOG.md diff adds the fix only under ## [3.4.2]; ## [Unreleased] remains empty. This does not meet the required changelog location.

Resolution

Add a concise Apple Silicon RetroArch core loading fix entry under ## [Unreleased]. Keep the dated 3.4.2 entry according to the release workflow.

Suggestions

• crates/rustynes-test-harness/tests/dependency_floor_audit.rs:688-716: webpki_roots_floor verifies that at least one 1.x version of webpki-roots is present and rejects non-1.x versions other than 0.26.11, but does not require 0.26.11 itself to be present. If tungstenite upgrades to webpki-roots 1.x directly and 0.26.11 drops out of Cargo.lock, this test will still pass with ["1.0.10"] instead of prompting removal of the global RUSTSEC-2026-0381 ignore in .cargo/audit.toml and deny.toml (whose expiration comment at deny.toml:907 names that exact condition). Assert versions.iter().any(|v| v == "0.26.11") alongside the 1.x presence check.
• crates/rustynes-test-harness/tests/libretro_buildbot_audit.rs:846-874: Consider extracting the variables: block check into a helper taking YAML text and adding a negative unit test (analogous to the_floor_refuses_what_it_exists_to_refuse in dependency_floor_audit.rs) verifying that STRIP_CORE_LIB: "0" placed only in before_script: or a comment is rejected.

This PR cuts the v3.4.2 "Countersign" patch release, disabling post-link stripping on the macOS arm64 libretro buildbot job so the linker's ad-hoc code signature remains valid, updating rustls-webpki and webpki-roots for recent RustSec advisories, and adding audit tests for both.

Blocking issues

None found.

Suggestions

• Historical v2.4.7 codename overwritten by global search-and-replace: When renaming v3.4.2 from "Keystone" to "Countersign" to avoid colliding with v2.4.7, an unscoped replacement also rewrote v2.4.7's own codename from "Keystone" to "Countersign" in SECURITY.md, docs/STATUS.md, and to-dos/ROADMAP.md. Restore **v2.4.7 "Keystone"** in those three files so v2.4.7 keeps its historical codename and does not collide with v3.4.2 "Countersign".
• Inline YAML comment handling in the_macos_arm64_core_is_not_stripped_after_signing: In libretro_buildbot_audit.rs, l.trim() == "STRIP_CORE_LIB: \"0\"" and l == " variables:" will fail if a trailing YAML comment is added to either line; stripping # comments first (as done in release_anchor_audit.rs) makes the check resilient to comments.

Nitpicks

• PR title: The PR title still reads release: v3.4.2 "Keystone", whereas CHANGELOG.md and .github/release-notes/v3.4.2.md use "Countersign".
• triple pre-release ordering: Collapsing all pre-release suffixes to 0 is sufficient when comparing against a stable floor (1, 0, 10, 1), but two pre-releases of the same major.minor.patch will compare equal if triple is ever reused for general version ordering.

This PR cuts the v3.4.2 "Keystone" patch release, disabling post-link stripping on the macOS arm64 libretro buildbot job (.gitlab-ci.yml) so the linker's ad-hoc code signature remains valid, updating rustls-webpki and webpki-roots in Cargo.lock with documented advisory ignores in deny.toml and .cargo/audit.toml, and adding audit tests for both.

Blocking issues

None found.

Suggestions

• dependency_floor_audit.rs: triple strips - suffixes before comparing (v.split(['-', '+']).next()) and defaults parse errors to 0. Under SemVer, a pre-release such as 1.0.10-alpha.1 sorts below 1.0.10, yet triple("1.0.10-alpha.1") < (1, 0, 10) evaluates to false. Consider rejecting - pre-release suffixes (or ordering them below the release tuple) and panicking on unparseable numeric segments instead of .unwrap_or(0).
• libretro_buildbot_audit.rs: In the_macos_arm64_core_is_not_stripped_after_signing, .take_while(|l| l.starts_with(" ")) stops at the first blank line inside variables:, whereas job allows blank lines within a block (l.is_empty() || l.starts_with(' ')). Allowing empty lines in the variables: slice (l.is_empty() || l.starts_with(" ")) would prevent a false test failure if comments and blank lines are added above STRIP_CORE_LIB in variables:.

Nitpicks

• SECURITY.md, docs/STATUS.md, to-dos/ROADMAP.md: The release codename "Keystone" duplicates v2.4.7 "Keystone" in the same lineage lists.

Blocking issues

None found.

Suggestions

• crates/rustynes-test-harness/tests/libretro_buildbot_audit.rs:820-823: take_while(|l| l.starts_with(" ")) stops at the first blank line inside variables:, whereas job() on line 798 permits empty lines (l.is_empty() || l.starts_with(' ')). Accepting empty lines (l.is_empty() || l.starts_with(" ")) prevents a blank line or comment block inside variables: from causing a false failure.
• crates/rustynes-test-harness/tests/dependency_floor_audit.rs:665-673: triple() falls back to 0 via .unwrap_or(0) if a version segment fails to parse or is missing. Returning an error or panicking on malformed semver strings avoids silently coercing bad input into 0.

Nitpicks

• crates/rustynes-test-harness/tests/dependency_floor_audit.rs:647: crates/rustynes-cosim/Cargo.lock is a separate lockfile in this repository; although it does not currently pull in webpki-roots, noting or asserting that in the test would make the workspace scope explicit.
• SECURITY.md:5: The codename "Keystone" was already used by v2.4.7 (prior reused codenames in this list used a " II" suffix, e.g., v2.4.9 "Plumbline II").

Review round 1: replies

Antigravity (no blocking findings), all handled in d55cf45:

• triple() mis-orders pre-releases and reads unparseable segments as 0. Valid. It now returns (major, minor, patch, release) with release 0 for a pre-release, ignores build metadata, and panics on a malformed segment. New cases: 1.0.10-rc.1 refused, 1.0.10+build.5 accepted, 1.x.10 panics. Mutation (pre-release counted as release): 2 of 5 tests fail.
• The variables: scan stops at a blank line. Valid, it now allows blank lines like the job parser does.
• The cosim lockfile is outside the floor (nitpick). A test now asserts it has no webpki-roots.
• "Keystone" duplicates v2.4.7 (nitpick). Valid. The maintainer renamed the release "Countersign"; only v3.4.2's 17 occurrences changed, v2.4.7's are untouched.

Copilot ("needs a closer look: the branch-built arm64 artifact still needs the pre-merge signature verification"): done. libretro's pipeline 125851 built this branch, and its arm64 core verifies with 0 of 538 pages mismatched, signed range intact, linker-signed. The maintainer loaded that build in RetroArch on an M5 Max (macOS 27.0.1), and it works.

CodeRabbit: the one inline finding is fixed and resolved.

Codex: no findings.

- Line 67: Update the YAML scan’s assertion predicate to match STRIP_CORE_LIB
only on lines with exactly four leading spaces, excluding deeper-indented
content while retaining the existing trimmed-value comparison.

Review comments at @docs/STATUS.md:
- Line 3: Update the v2.4.7 history entry in STATUS.md and its copied
occurrences in SECURITY.md and to-dos/ROADMAP.md from “Countersign” to
“Keystone,” while preserving v3.4.2’s codename unchanged.

Final round (c6033d5)

No blocking findings. All 44 checks pass, every thread is resolved.

• The v2.4.7 codename overwritten (Antigravity, 23:36 round; CodeRabbit inline): fixed in c6033d5. v2.4.7 reads "Keystone" in all six places, and v3.4.2 reads "Countersign".
• webpki_roots_floor checks that at least one 1.x exists (00:06 round): it does, and it also fails on any 1.x below 1.0.10 and on any 0.26 other than 0.26.11, which is the property the ignore needs. Left as is.
• Extract the variables: check into a helper taking YAML text (00:06 round): a reasonable refactor, not a defect. It is pinned by two mutations as it stands. Left for a later pass.

Merging on green.
