Closes DEC-032. Restores the canonical Android ABI set
{arm64-v8a, armeabi-v7a, x86_64} per SDD-073 item 4 / SDD-118 item 3.
Root cause was the audiopus_sys + cmake-rs + NDK toolchain-file gap:
cargo-ndk 4.x sets ANDROID_ABI / ANDROID_PLATFORM as env vars per
invocation, but upstream cmake-rs 0.x does not forward them to the
child cmake invocation as -D variables, so armeabi-v7a and x86_64
configure steps fell through to the toolchain-file default and
failed to build.
Fix:
- Cargo.toml: add a workspace [patch.crates-io] stanza pinning the
cmake crate to fork pr2502/cmake-rs @ commit
bdad5edc569d82151922c5c6c4685b1563f12aa1 (branch android-build),
which carries cmake-rs PR #257
(https://github.com/rust-lang/cmake-rs/pull/257). The patch is a
9-line addition that forwards ANDROID_ABI and ANDROID_PLATFORM
from the env to the child cmake as -D variables.
- Cargo.lock: regenerated by 'cargo update -p cmake'; the lone
cmake entry now points at the fork rev.
- apps/chanora_flutter/android/app/build.gradle.kts: restore
abiFilters to {arm64-v8a, armeabi-v7a, x86_64}; remove the
TODO(x86_64/armv7 follow-up) comment.
- docs/governance/product-decision-register.md: mark DEC-032 as
Resolved (2026-05-18) with the resolution mechanism, update the
§3 / §7 rows, and append a 0.9.8.1 change-history entry.
Verification (host: Linux):
cargo update -p cmake -> pulled fork rev
cargo check --workspace --all-targets -> PASS
cargo test --workspace -> PASS (no regressions)
cargo ndk --platform 28 -t arm64-v8a build -p chanora_bridge -> PASS
cargo ndk --platform 28 -t armeabi-v7a build -p chanora_bridge -> PASS
cargo ndk --platform 28 -t x86_64 build -p chanora_bridge -> PASS
Upstream tracking: re-evaluate the [patch.crates-io] override once
cmake-rs PR #257 merges and a fresh cmake release lands on
crates.io; at that point switch to a plain dep bump and remove the
override.
Author SysRS-310 ratifying the macOS minimum runtime baseline at 10.15
(Catalina) at the SysRS layer, parallel to SysRS-286 (iOS 13.0) and
SysRS-288 (Android API 28).
Closes the Wave 1.5 traceability-audit deferred-but-optional follow-up.
ID allocation: SysRS-310 (not SysRS-290, which is already allocated to
MVP single-active-server-connection scope); monotonic numbering
preserved.
Cross-references SAD-087, SDD-119, SysRS-286, SysRS-288. Verification:
Review + Platform Test on a macOS 10.15 system. Raising the baseline
(e.g., to 11.0 / Big Sur) requires a DEC entry.
Trace: SysRS v0.9.11, SAD-087, SDD-119.
Resolve the macOS half of the SDD-119 item 3 single-source-of-truth follow-up. The chanora_bridge cdylib macOS deployment-target floor ('10.15') was previously hard-coded at 7 sites across Podfile and chanora_bridge.podspec; this commit collapses them to a single Ruby constant declaration in a new SoT file.
Selected Option B (Ruby constant) over Option A (.xcconfig — rejected because the podspec prepare_command runs before any xcconfig is applied) and Option C (versioned text file — rejected as overkill given both consumers are already Ruby). Realizes SAD-087(a)'s 'single macOS build-configuration location' mandate.
Out of scope: the pbxproj 'MACOSX_DEPLOYMENT_TARGET = 10.15' lines (565/666/717) belong to the PBXProject default config and are independently overridden to '11.0' at the Runner PBXNativeTarget level; they are the Runner app's floor, not the bridge cdylib's floor. The iOS half (IPHONEOS_DEPLOYMENT_TARGET=13.0) remains an open follow-up.
Files: new apps/chanora_flutter/macos/macos_deployment_target.rb (MACOS_BRIDGE_DEPLOYMENT_TARGET = '10.15'.freeze); Podfile + chanora_bridge.podspec require_relative the constant and consume it at 7 sites; docs/architecture/sdd.md SDD-119 item 3 rewritten + Notes bullet updated + v0.9.17 changelog entry.
Canonical baseline lives at crates/chanora_audio/benches/baselines/x86_64-unknown-linux-gnu.json
and is updated only via the bench-baseline-update.yml workflow.
