jackandGitHub 820c933958 Harden PTT audio and the 1.7.1 release (#1423 )

Centralize PTT and voice audio-session ownership, harden courier/bridge/outbox delivery and recovery, correct location and delivery-state races, add privacy/release metadata, and ship reproducible universal Arti slices with Release CI coverage.

Validated by the full iOS suite, repeated audio/fragment/performance regressions, BitFoundation tests, strict lint and dead-code analysis, universal iOS Release builds, and iOS/macOS archives.

Arti Binary Provenance

This repo vendors a prebuilt Arti static-library xcframework at:

localPackages/Arti/Frameworks/arti.xcframework

SwiftPM links it through localPackages/Arti/Package.swift as the binary target named arti. Treat changes to this artifact like dependency updates: review the Rust sources, lockfile, build script, produced headers, and artifact hashes together.

Source Inputs

Rust workspace: localPackages/Arti/Cargo.toml
Crate: localPackages/Arti/arti-bitchat
Dependency lockfile: localPackages/Arti/Cargo.lock
Build script: localPackages/Arti/build-ios.sh
Exported C header: localPackages/Arti/Frameworks/include/arti.h

The crate declares rust-version = "1.90" and uses arti-client / tor-rtcompat 0.38 with minimal Tokio/Rustls features. The current lockfile requires Rust 1.90 or newer. The build script currently targets:

aarch64-apple-ios
aarch64-apple-ios-sim
x86_64-apple-ios
aarch64-apple-darwin
x86_64-apple-darwin

It builds release static libraries with size-oriented flags (opt-level=z, fat LTO, one codegen unit, panic=abort, stripped symbols), normalizes static-archive metadata with xcrun libtool -static -D, then packages them with xcodebuild -create-xcframework.

Regenerating The Artifact

From the repo root:

cd localPackages/Arti
rustup toolchain install 1.96.0
rustup target add --toolchain 1.96.0 aarch64-apple-ios aarch64-apple-ios-sim x86_64-apple-ios aarch64-apple-darwin x86_64-apple-darwin
rustup run 1.96.0 cargo install cbindgen --version 0.29.4 --locked
./build-ios.sh

build-ios.sh defaults to the audited 1.96.0 toolchain and refuses a rustc version other than 1.96.0; it likewise requires cbindgen 0.29.4. Set RUST_TOOLCHAIN, RUSTC_VERSION, or CBINDGEN_VERSION explicitly only when intentionally updating the binary provenance and hashes below.

After rebuilding, verify that:

Cargo.lock changes are intentional and reviewed.
Frameworks/include/arti.h still matches the exported FFI functions used by TorManager.
Frameworks/arti.xcframework contains iOS device arm64, universal iOS simulator arm64+x86_64, and universal macOS arm64+x86_64 slices.
The main app still passes iOS tests and the macOS build.

Audited Rebuild

The July 2026 artifact below was rebuilt from source on this host with:

rustc 1.96.0 (ac68faa20 2026-05-25)
cargo 1.96.0 (30a34c682 2026-05-25)
rustup 1.29.0 (28d1352db 2026-03-05)
cbindgen 0.29.4
Xcode 26.6
Build version 17F113

Rust 1.86.0 was also checked during the audit and no longer builds this lockfile because typed-index-collections@3.4.0 requires Rust 1.90.0 or newer.

The build script now normalizes static-archive metadata and writes a stable xcframework Info.plist. Two consecutive no-source-change rebuilds on this host produced the same hashes below.

Review Checklist

Record rustc --version, cargo --version, cbindgen --version, and xcodebuild -version in the PR when refreshing the binary.
Include the hash output above after any binary change.
If a rebuild changes only xcframework/library bytes, record the new hashes and app validation evidence in the PR.
Keep target/, .build/, and .swiftpm/ out of source control.
Do not accept an xcframework-only update without matching source, lockfile, or build-script evidence explaining where it came from.
