Critical-path math (cargo workspace 105 crates × 3 matrix targets): - Current profile: opt-level=z + lto=true + codegen-units=1 = compile cost ~10-20× over default; observed wall-time ~17min/release run - After P1+P2 stack: predicted ~4-5min cold, ~1.5min warm == P1 — _primitives/_rust/Cargo.toml profile.release == - lto: true → "thin" (full LTO is 3-5× slower; thin keeps most opts) - codegen-units: 1 → 16 (parallel codegen restored, was serial) - Binary size cost: ~10-15% larger (acceptable for non-embedded targets) - VERIFIED: cargo check --workspace exits clean [REAL: ran in this session; 0 errors, warnings only] == P2 — mold linker for Linux targets == - New: _primitives/_rust/.cargo/config.toml (7 LOC) * x86_64-unknown-linux-gnu + aarch64-unknown-linux-gnu use clang+mold * macOS targets unaffected (use system ld + LLVM) - New step in .github/workflows/release.yml::build-release: Install mold linker (Linux only) — apt-get mold clang Gate: `if: contains(matrix.target, 'linux')` - Inserted AFTER rust-toolchain BEFORE rust-cache - Predicted gain: link phase 60s → 6s on Linux entries == P3 — explicitly NOT applied == - Path-filter on docs-only commits considered + rejected per task spec: Release tags should always rebuild even if commit only touches docs. Files: - _primitives/_rust/Cargo.toml (+2/-2 LOC) - _primitives/_rust/.cargo/config.toml (NEW, 7 LOC) - .github/workflows/release.yml (+5/-0 LOC, mold install step) [ESTIMATE-HTC: rustc + mold benchmarks claim 3-5× and 5-10× respectively on full release builds — not re-benchmarked on this 105-crate workspace yet; will measure on next v* tag push] NOTE: this commit does NOT retag — keigit publish 401 issue is on the keigit-server side (verified: token works locally, 401 from runner IP) and requires user-side action (fail2ban/Caddy whitelist GitHub Actions IP ranges on 45.77.41.204). After user fixes that, next tag will verify both speed gain AND publish success. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
