Baseline (pre-refactor)

Recorded before the principal-engineer refactor began. Toolchain: rustc 1.98.0 (stable, via rustup), workspace pinned stable in rust-toolchain.toml, rust-version = "1.85" (MSRV claim).

Gates

• cargo check --workspace --all-targets --all-features — pass (after build repair)
• cargo test --workspace --all-features — 151 tests pass (139 unit + 12 integration; doc-tests 0)
• cargo clippy --workspace --all-targets --all-features -- -D warnings — pass (after repair)
• cargo fmt --all -- --check — pass

Examples

• basic_factorization (91) — pass, 1 CVP instance
• batch_factorization — 5/6 pass; 1022117 (20-bit) fails: insufficient smooth relations: needed 14, found 3 (confirms the 20-bit entry exceeds the documented 14-bit test scope)
• test_factorization — 18/18 pass

Benches (criterion, quick mode, single-threaded default)

• tensift-core first 1000 primes: 11.4 us
• tensift-lattice: lattice construction dim=12: ~5.3 us; LLL reduction dim=12: ~2.12 ms
• tensift-tensor sampler: ~906 us
• tensift-algebra: factor 91: ~191 us; factor 5183: ~908 us; factor 8633: (recorded in run)

Size

• Total source LOC (crates/*/src): 13,427
  • tensift-core 938, tensift-lattice 4,056, tensift-tensor 5,310, tensift-sampler 686, tensift-algebra 2,246, tensift-cli 191
• Public items per crate: core 32, lattice 49, tensor 98, sampler 8, algebra 33

Known pre-existing defects found during baseline

1. Workspace did not compile against pinned rand 0.10 (RngExt split, choose_multiple→sample rename, removed rand::RngCore re-export).
2. parallel_sample in tensift-core was dead code that blocked compilation.
3. One clippy question_mark violation in factor extraction.
4. batch_factorization includes a 20-bit case beyond documented scope.
