The replacement is ONE build graph filtered by a nextest filterset, so the translation from the registry tokens to that expression is the new load-bearing step. These rows fail now (--filterset is not a flag yet) and pin BOTH polarities: each recognised token becomes exactly one clause, and an unrecognised token is ENV (exit 2) rather than a silently dropped target — a dropped token is a tree-reader test that stops running while the step stays green, which is the failure mode the registry exists to prevent. Row 22 counts clauses against registry lines so nothing can be dropped in bulk either. Row 21 was written fail-open first (`grep -q ":--" && LEFTOVER || NONE-LEFT` passes on EMPTY output) and is hardened here before it was ever green.

The binary-id forms are nextest's own and were VERIFIED on this workspace with cargo-nextest 0.9.132 (`cargo nextest list --message-format json`), not assumed: a lib suite's id is the bare package name, an integration target's is `package::target`, a bin's is `package::bin/name`. MEASURED on lambda, warm target dir (both listings from the same tree): one graph 65263 tests, 41 binaries, 39 suites with >=1 test build+list 96s, execution 220.2s, 316s wall, rc=0, 65263 passed 20-crate 65204 tests, 40 suites chain (20 distinct crates, not 26 — the 41 tokens group into 20) The two sets are NOT identical and the difference is entirely FEATURE UNIFICATION, never target selection: * A\B = 258 tests. Features the workspace resolve unifies ON and a per-package resolve leaves OFF (aprender-core hf_hub / inspect::safetensors / format::homomorphic / format::quantize, aprender-orchestrate mcp_json, aprender-test-lib async driver). * B\A = 199 tests, and ZERO of them exist under the workspace resolve at all — they are cfg(feature)-gated out. 197 are aprender-test-lib's browser mock suites, 2 are aprender-present-cli::gate_can_fail. So the FULL tier, which is `--workspace --lib`, never ran them either: the old chain was compiling a DIFFERENT aprender-test-lib than the tier it is supposed to approximate. Aligning the quick tier with the full tier's resolve is the fix, not a loss. * Suite selection is otherwise exact: 41 clauses -> nextest reports "Starting 65263 tests across 41 binaries". The two suites with no tests are aprender-core::setfit_conformance and ::falsification_spec_v10_tests, built and selected in BOTH but empty under default features (they are the full tier's --features setfit targets). * `--bins` maps to `kind(bin)`, not to the whole package. The old chain ran `cargo nextest run -p aprender-present-cli` with NO flags, so it also swept up `gate_can_fail` — an integration target that is in neither the registry nor the unwired ledger, i.e. not a tree reader at all. `kind(bin)` selects exactly what the token claims: the cfg(test) unit tests inside the bins of a crate that has no src/lib.rs (which is the only reason the token exists — `--lib` there is `error: no library targets found`). Both quick-tier steps drop to `timeout-minutes: 20`. 60 is the number that let this step burn 55 minutes on a one-file YAML PR (run 34449608126) and then die at the cap under fleet load on #3063 (#3070); the budget is the assertion. check_tree_reader_tests.sh is untouched and still derives the same 41 targets: its `full_tier_excludes` regex requires `--workspace --lib` followed IMMEDIATELY by ` --exclude`, and the new line has `--tests` in between, so it still reads the full tier's line and only that one (verified by running the regex).

Lint is clean on x86. On aarch64, `cargo clippy --all-targets -- -D warnings` fails in aprender-compute and aprender-present-terminal, and so does the job's `-p aprender` fallback, because both crates are in the facade's dependency closure. - Four SIMD detectors end with `#[cfg(aarch64)] { return Neon; } Scalar`, which leaves the Scalar tail unreachable on ARM. Each tail is now a cfg'd block. - x86-only helpers were compiled on ARM and never called there: the Q6_K value extractor, the BLIS AVX-512 packers, the prefetch and NT-store thresholds, and the 32x6 packing import. Each now carries the x86_64 cfg of its only callers. - rounding.rs imported the NEON backend and never used it. - Five more detectors, in aprender-core, aprender-serve and trueno-ublk, had the same unreachable tail. They only showed up once the crates above them compiled. - Two x86_64-only BLIS packers in compute.rs are also dead on ARM. The cfg belongs on the functions, but compute.rs already carries 11 complexity violations, and the pre-commit gate refuses any edit to the file until it is decomposed. Until then, `mod compute;` carries a non-x86 `expect(dead_code)` with that reason. `expect` becomes an error as soon as the packers stop being dead. One of the dead functions was a real defect. #2567 made the non-x86 matmul_q4k_f32_parallel actually parallel (its doc records 1.21x on GB10), but the only call site sat inside the x86_64 block, so every ARM machine still ran the serial Q4_K kernel. The dispatcher now calls it on non-x86 above the same 8M-element threshold. A new test checks the threaded path against the serial one on every arch; the coverage module that exercised it only builds on x86_64.
