kernel-cases: the rig runs SMLib only and keeps each run's SMLib dumps

Browse Source 
SMLib is the only kernel now. cargo xtask kernel-cases ran every case once
per kernel asked for (--kernel default|smlib|both), setting
SOLIDCRAFT_KERNEL per run, and wrote a column per kernel; solidcraft-cli no
longer reads that variable.

The rig and the ladder run each case once, through solidcraft-cli built with
--features smlib (cargo run passes it), and report one result per case:
--kernel and the env var are gone. Each run has an output folder (--out,
default target/kernel-cases, target/kernel-ladder for the ladder) holding
results.json (every case's full result, which --results used to write on
request) and dumps/<area>-<case>/: every case runs with
solidcraft-cli kernel-cases --dumps=<out>/dumps, so a failed SMLib call
leaves its inputs for replay.

The ladder's golden holds one entry per case: golden.json is the last
recording's smlib entries, which predate SMLib running every case (its
reason says so); record it again after the first SMLib-only run.

docs/kernel-cases.md (until the next run regenerates it),
tests/kernel-cases/README.md, docs/kernel-smlib-sweeps-shell.md (its truck
column and comparisons dropped), xtask's and solidcraft-cli's usage text:
one kernel. Nothing was run.

clippy -p xtask --all-targets: clean.

# Kernel regression rig
Generated by `cargo xtask kernel-cases`. Every geometry case the old kernel (truck) got wrong, as an issue, a PR or a crash report recorded it, is a use case in [`tests/kernel-cases/`](../tests/kernel-cases/) with its own right answer: numbers from analysis or a hand calculation (**analytic**) where the geometry has them, and otherwise the invariants (**invariants**): the operation succeeds, or refuses cleanly where that is the right answer; each body is one closed shell that passes the record's structure and geometry checks and, in builds with SMLib, SMLib's own check; the expected face, edge and vertex counts. Never a kernel's output, and never a commercial kernel's.

Never a kernel's output, and never a commercial kernel's.
Each kernel is graded against the case, never against the other kernel. **default** is the kernel SolidCraft ships today; **smlib** runs with `SOLIDCRAFT_KERNEL=smlib`. A failing case stays failing until its kernel is fixed; there is no workaround on SolidCraft's side. See [`tests/kernel-cases/README.md`](../tests/kernel-cases/README.md) for the format.
The cases run on SMLib, SolidCraft's kernel. A failing case stays failing until the kernel is fixed; there is no workaround on SolidCraft's side. A failed SMLib call leaves its inputs for replay in the run's output folder (`target/kernel-cases/dumps/<area>-<case>/`).

# SMLib vs truck: sweeps, threads, shell and offset
# SMLib: sweeps, threads, shell and offset
A triage of the regression rig's sweeps, threads and shell cases, and of the ladder's tiers 03
(analytic profiles), 04 (spline profiles), 06 (threads) and 09 (shells and offsets): 169 cases,
each run on both kernels (`solidcraft-cli kernel-cases`, `SOLIDCRAFT_KERNEL` unset and `smlib`)
on `kernel-smlib` at 4b8953726. Each kernel is graded against the case's own answer
([kernel-cases.md](kernel-cases.md)), not against the other kernel. This page lists only the
cases where SMLib does not pass, grouped by what goes wrong, worst first; it is kept by hand as
fixes land.
each run on SMLib (`solidcraft-cli kernel-cases`) on `kernel-smlib` at 4b8953726 and graded
against the case's own answer ([kernel-cases.md](kernel-cases.md)). This page lists only the
cases that do not pass, grouped by what goes wrong, worst first; it is kept by hand as fixes

| | Cases | truck passes | SMLib passes |
|---|---|---|---|
| sweeps | 83 | 55 | 51 |
| threads | 28 | 10 | 11 |

| ladder 03, 04, 06, 09 | 40 | 28 | 26 |
| **all** | **169** | **98** | **99** |
SMLib passes 18 cases truck fails (shells of tapered and rounded bodies, offset faces next to
freeform faces, bent and hollow lofts, the 36 twisted blades). Truck passes 17 that SMLib does
not: 11 of them are sweeps SMLib has no path for yet (group G), 6 are below.

A thread off its hole's or shaft's size is refused on this branch (the owner's rule): those
cases pass on both kernels by refusing, and are not listed.
cases pass by refusing, and are not listed.
## A. Wrong geometry (worst)
| Case | truck | SMLib | SMLib's result |
|---|---|---|---|
| sweeps/2667-revolve-half-disc-three-quarters | pass | fail | a half disc on the axis turned 270°: SMLib makes a quarter ball turned inside out (V = -226, want 679) |
| sweeps/3528-revolved-dome-cut-by-a-ball-on-its-seam | pass | fail | the ball's cut is lost where it crosses the revolve's seam: V 48118, want 46425 |
| sweeps/2847-loft-rectangles-turning-through-half-a-turn | fail | fail | inside out (V = -127, want 2262); truck's is wrong too (V = 126) |
| sweeps/450-revolve-spherical-shell-sketched-off-the-origin | crash | fail | two shells where one is wanted, which the B-rep record can't close (truck's process dies) |
| Case | SMLib | SMLib's result |
|---|---|---|
| sweeps/2667-revolve-half-disc-three-quarters | fail | a half disc on the axis turned 270°: SMLib makes a quarter ball turned inside out (V = -226, want 679) |
| sweeps/3528-revolved-dome-cut-by-a-ball-on-its-seam | fail | the ball's cut is lost where it crosses the revolve's seam: V 48118, want 46425 |
| sweeps/2847-loft-rectangles-turning-through-half-a-turn | fail | inside out (V = -127, want 2262) |
| sweeps/450-revolve-spherical-shell-sketched-off-the-origin | fail | two shells where one is wanted, which the B-rep record can't close |
## B. Crash
| Case | truck | SMLib | SMLib's result |
|---|---|---|---|
| ladder/09-shells-and-offsets/011-part-shell | fail | crash | step 21 (solid.fillet) on the SMLib body: curve blend internal error "Two same vertices cannot construct an edge"; the fillet is the blends work's, not this page's |
| Case | SMLib | SMLib's result |
|---|---|---|
| ladder/09-shells-and-offsets/011-part-shell | crash | step 21 (solid.fillet) on the SMLib body: curve blend internal error "Two same vertices cannot construct an edge"; the fillet is the blends work's, not this page's |
## C. Threads: the groove's boolean fails SMLib's check
The groove (SMLib's screw sweep) cuts the body, and the result fails SMLib's own check: vertex
gaps of 1–6e-5 mm against vertex tolerances of 4–20e-6 mm (Test #0/#2 Bad Gap), an edge whose
geometry fails validation (Test #61), or a trim curve that does not lie on its edge when the
result is read back (SMLib export: pcurve). Truck's faceted groove fails SMLib's check on the
same cases with 6 to 752 failed tests.

# Kernel regression rig
Every geometry case the old kernel (truck) got wrong, recorded in an issue, a pull request or a
crash report, is a use case here with its own right answer. The rig holds every kernel to all of
crash report, is a use case here with its own right answer. The kernel, SMLib, is held to all of
them. `cargo xtask kernel-cases` runs them and writes [`docs/kernel-cases.md`](../../docs/kernel-cases.md).
```sh
cargo xtask kernel-cases # the default kernel
cargo xtask kernel-cases --kernel both --cli target/release/solidcraft-cli # and SMLib
cargo run -p solidcraft-cli -- kernel-cases tests/kernel-cases/booleans/<id> # one case
cargo run -p solidcraft-cli --features smlib -- kernel-cases --dumps=/tmp/dumps <case-dir> # failing SMLib calls leave replayable inputs
cargo xtask kernel-cases # every case
cargo xtask kernel-cases --cli target/release/solidcraft-cli --out /tmp/run # with a CLI already built
cargo run -p solidcraft-cli --features smlib -- kernel-cases tests/kernel-cases/booleans/<id> # one case
```
For the `smlib` column, build `solidcraft-cli` with `--features smlib` (after
`scripts/fetch-smlib.sh`). The rig sets `SOLIDCRAFT_KERNEL=smlib` for those runs.
The CLI needs `--features smlib` (after `scripts/fetch-smlib.sh`); without it every operation
answers that SMLib is not built. The run's output folder (`--out`, default `target/kernel-cases`)
gets `results.json`, every case's full result, and `dumps/<area>-<case>/`: the inputs of each
SMLib call a case failed in, for replay (the CLI's `--dumps=DIR`, which the rig always passes).
## Rules
- **The answer never comes from a kernel.** Not from truck's output, nor any commercial
kernel's. It comes from analysis or a hand calculation, or else from the invariants below.
