Summary

This PR bumps the swift-nio family in the two demo Package.resolved files to clear all 12 open Dependabot alerts. The root Sublimation package has no external dependencies, so it is unaffected.

Alerts fixed

#6, #7, #8, #9, #10, #11, #12, #13, #15, #17, #18, #19

Package Alerts DemoServer before → after Xcode demo app before → after Required
swift-nio #8, #9, #10, #12, #13, #17 (GHSA-rj37-6j9x-74q6, GHSA-r3rc-9hpw-54v9, GHSA-cq87-8r7h-962v) 2.44.0 → 2.103.0 2.63.0 → 2.103.0 ≥ 2.100.0
swift-nio-extras #11, #15 (GHSA-6ph5-fww6-vfwv) 1.15.0 → 1.35.1 1.21.0 → 1.35.1 ≥ 1.34.1
swift-nio-http2 #6, #7, #18, #19 (GHSA-4px2-pw77-vc85, GHSA-xvr7-p2c6-j83w) 1.23.1 → 1.46.0 1.30.0 → 1.46.0 ≥ 1.44.0

How the files were updated

  • Demo/SublimationDemoServer/Package.resolved: I first ran swift package update swift-nio swift-nio-extras swift-nio-http2. That only reached nio 2.50.0, extras 1.22.0 and http2 1.27.0, because the other pins (swift-collections 1.0.3, swift-atomics, vapor 4.67.3, and others) held them back. So I ran a full swift package update within the existing manifest constraints. vapor goes from 4.67.3 to 4.122.2 and stays on 4.x (from: "4.66.0"). The manifests are unchanged.
  • Demo/SublimationDemoApp.xcodeproj/.../Package.resolved: I regenerated this file with xcodebuild -resolvePackageDependencies. Removing only the three nio pins wasn't enough, because Xcode re-selected the old versions to fit the remaining pins. The regenerated file now matches the DemoServer file pin for pin. It drops stale pins (OpenAPIKit, swift-openapi-*, swift-argument-parser, Yams) that are no longer in the dependency graph.

Pre-existing issue (not introduced here)

The demo server's Package.swift still depends on .product(name: "SublimationVapor", package: "Sublimation"), but that product was removed from the root package in #40. Because of this, swift build in Demo/SublimationDemoServer and xcodebuild -resolvePackageDependencies on the demo project already fail on main, with the same error:

error: 'sublimationdemoserver': product 'SublimationVapor' required by package 'sublimationdemoserver' target 'SublimationDemoServer' not found in package 'Sublimation'.

To work around this when resolving the Xcode project, I removed the SublimationVapor line locally while running xcodebuild and didn't commit that change. It doesn't affect the resolved file, because the product came from the local root package, which has no remote dependencies. Fixing the demo is out of scope for this security PR.

Build / test results (Xcode 27.0, Swift 6.4)

  • ✅ Repo root: swift build succeeds. swift test passes (2 XCTest tests, 0 failures).
  • ✅ Updated demo dependency graph: I copied the demo server into a scratch directory with the SublimationVapor reference removed and built it with swift build --build-system native. Vapor 4.122.2, NIO 2.103.0, nio-http2 1.46.0, nio-extras 1.35.1 and the rest of the graph compiled successfully. The only error came from the scratch copy's own import Sublimation, because the copy's manifest no longer declared that dependency.
  • ⚠️ swift build in Demo/SublimationDemoServer fails because of the pre-existing missing-product error above. It fails the same way on main.
  • CI (.github/workflows/Sublimation.yml) builds and tests only the root package. The root package's resolution is unaffected by this change.

Summary by CodeRabbit

  • Chores
    • Expanded automated build and test coverage across supported Swift versions, platforms, and package configurations.
    • Updated code security analysis and added automatic cleanup of build caches when branches are deleted.
    • Improved caching and setup for development tools, and updated formatting and lint checks.
    • Some documentation and metadata changes no longer trigger build workflows.

Fixes Dependabot alerts 6-13, 15, 17-19 (swift-nio, swift-nio-extras,
swift-nio-http2) in Demo/SublimationDemoServer and the demo Xcode
project's Package.resolved.

- swift-nio 2.44.0/2.63.0 -> 2.103.0
- swift-nio-extras 1.15.0/1.21.0 -> 1.35.1
- swift-nio-http2 1.23.1/1.30.0 -> 1.46.0

The other pins held these three back, so both files were re-resolved
within the existing manifest constraints (vapor stays on 4.x).

📝 Walkthrough

Walkthrough

The PR replaces fixed CI lanes with configurable platform matrices, adds mise-based tool setup and lint execution, adds cache cleanup for deleted branches, and updates the CodeQL workflow and Swift analysis environment.

Changes

Build and lint workflows

Layer / File(s) Summary
Matrix selection and platform builds
.github/workflows/Sublimation.yml
The workflow selects reduced or full matrices and defines Ubuntu, Windows, Android, and macOS build lanes. Coverage processing and uploads run conditionally where supported.
Mise tools and lint integration
mise.toml, Mintfile, Scripts/lint.sh, .github/actions/setup-tools/action.yml, .github/workflows/Sublimation.yml
Tool versions move from Mintfile pins to mise. The lint script uses mise-managed tools and tracks command failures. A shared action caches mise installations, and the workflow adds a separate lint job.

Deleted-branch cache cleanup

Layer / File(s) Summary
Cache cleanup workflow
.github/workflows/cleanup-caches.yml
A branch-deletion workflow lists and deletes Actions caches for the deleted branch ref, then logs the deletions and total.

CodeQL workflow

Layer / File(s) Summary
CodeQL analysis workflow
.github/workflows/codeql.yml
The workflow enables the analyze job, adds concurrency control, upgrades the checkout and CodeQL actions, and uses macOS 26 with Xcode 26.6 for Swift jobs.

The macOS job failed on macos-14: the "iPhone 15" / iOS 18.1 simulator
no longer exists on that image, and every v4 action targets the
deprecated Node 20 runtime.

- Rebuild Sublimation.yml on brightdigit/swift-build@v1, mirroring
  MistKit: a configure job picks a full matrix (main, semver branches,
  PRs into them) or a minimal one; Ubuntu (6.1-6.4, noble/jammy, wasm),
  Windows, Android, macOS SPM/iOS, and all Apple platforms on Xcode
  26.6 and the Xcode 27 preview image
- Bump to checkout@v6, codecov-action@v6, swift-coverage-action@v5
- Add concurrency cancellation and run on push to main + pull requests
- Replace Mint with mise (swift-format 602, periphery 3.7.4) and a
  shared setup-tools composite action; lint runs on Ubuntu after builds
- Rewrite Scripts/lint.sh without the hard-coded Homebrew mint path
- Re-enable CodeQL on macos-26 / Xcode 26.6 with codeql-action@v4
- Add cleanup-caches workflow for deleted branches

deletions but not tag deletions; update the cleanup job containing the ref

the collected cache array and use its length in the deletion count. Preserve the
existing owner, repo, and ref parameters.

Review comments at @.github/workflows/Sublimation.yml:
- Around line 39-41: In the “Determine matrix scope” step, pass REF, EVENT, and
BASE_REF through the step’s env block and use those environment variables in the
shell instead of interpolating GitHub context values into shell assignments.

Review comments at @Scripts/lint.sh:
- Line 48: Pass the header check through run_command in the lint script, keeping
its existing arguments, so failures from Scripts/header.sh are counted and the
Lint target does not report success after a failed check.
