📝 Summary

Summary by CodeRabbit

• Chores
  • Updated an internal dependency; no user-visible changes are noted.

The frontend Cargo manifest upgrades the zip dependency from version 8 to version 9. It keeps default features disabled and the deflate feature enabled.

Changes: Frontend dependency

Layer / File(s)	Summary
Update zip dependency crates/rusty2600-frontend/Cargo.toml	The zip dependency changes from version 8 to version 9. Default features remain disabled, and deflate remains enabled.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~3 minutes

Change: Other

Merge Risk: 🔴 Critical · up to eb6d3

The frontend no longer compiles after this dependency update because ZIP entry names now return a fallible result. Fix the call before merging.

Security architecture risk: 🔵 Low · up to eb6d3

The existing extraction limits and success-only ROM loading remain in place. However, the new library reportedly changes the filename API in a way the current consumer does not handle. Compatibility and runtime behavior remain unconfirmed; no introduced security vulnerability was established.

Retained concerns

• Low · architecture · inferred: The unchanged ROM extractor appears incompatible with the new dependency's fallible filename API. The reported v9 return type cannot satisfy entry.name().to_string(), preventing the consumer from compiling rather than creating a demonstrated runtime exploit.

Security review details

Security Blast Radius

• observed — The demonstrated exposure is frontend processing of user-supplied archive bytes and subsequent browser, WASM, or desktop ROM loading. The extraction helper returns bytes and an archive-entry name; it does not extract files onto the filesystem.

Trust Boundaries and Controls

• observed — Untrusted ZIP bytes reach dependency parsing before application-level entry filtering and bounded reads. Directories and non-ROM extensions are skipped. The output-read limit is not evidence of a bound on archive-parser metadata processing or total processing time.

Resilience and Maintainability Implications

• observed — The inspected callers gate ROM detection, pending-byte publication, or emulator loading on successful extraction. Failed reads and oversized output do not publish the helper's partial buffer through these paths. This preserves the existing source-level failure-containment ordering.

Bot Review Adjudication (Antigravity + CodeRabbit):

• Addressed CodeRabbit's inline finding on entry.name() in crates/rusty2600-frontend/src/rom_archive.rs:105 for zip 9.0.0 (entry.name().map_err(|e| RomArchiveError::Malformed(e.to_string()))?.into_owned()) in the consolidated dependency PR.

[doublegate]

Superseded by consolidated dependency PR #49.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
