Release 0.40.0-rc.1

The packaging action can't read a hyphenated version from the tarball's name, so the job gives it a name without the hyphen and renames the package back. A hyphenated version no longer fails the build if its Arch job fails; a plain version still does.

 ## Screenshots of the behavior (when observable)
 
+Put the picture or video here in the description. A file in the diff doesn't count: a maintainer has to be able to see what this is without opening the changed files.
+
 For observable CAD, UI or model behavior, include actual descriptive screenshots or a short recording from a small reproduction. This includes kernel, geometry, assembly and backend effects that can be shown in the app. Coding agents should run the app and capture the evidence themselves, rather than asking a human for evidence they can produce. Show the actual failure/result, preferably before and after, with brief steps, expected/actual behavior and annotations where helpful.
 
 Flowcharts and Mermaid diagrams cannot substitute for evidence of visible behavior. Use diagrams for architectural reasoning when actual screenshots cannot illustrate the point. Changes with no useful observable behavior may omit screenshot/video evidence. Exclude private designs and sensitive details; attach media or link to an accessible recording rather than committing generated review artifacts.

+# The kernel rig and the complexity ladder as a regression gate. A plan job maps a pull request's
+# changed files to the rig areas they can affect (scripts/ci/kernel_rig_plan.py): an area runs

+# runs when the shared core in tests/kernel-cases/PATHS-ALL changes, and when the solidcore pin in
+# the root Cargo.toml and Cargo.lock moves (the plan reads their diff); the ladder runs whenever any
+# area does. One job then builds solidcraft-cli once (release), checks that every
+# registry command has a case or an exemption (tests/kernel-cases/EXEMPT), and hands the CLI to a
+# matrix of shards as an artifact, one per selected area plus the ladder, in parallel, so the

+Please include what you found, the steps you ran to reproduce it (a design file, command or MCP
+request), the version and platform, and what an attacker gains. I'll acknowledge the report as soon
+as I can, keep you updated in the advisory, and credit you when the fix is published unless you'd
+rather stay anonymous.
 
-Areas where reports are especially useful:
+## What counts as a security issue
 
-- opening untrusted design, STEP, STL or 3MF files (crashes, excessive memory or CPU, path tricks)
-- the MCP server and the control API (file access outside the allowed folders, command injection)
-- the web app (anything reaching beyond the page's own storage)
-- release packages and the update paths (AppImage, Flatpak, MSI, deb, rpm, snap)
+Advisories are for problems where someone gets something they shouldn't, without already having
+access to your computer or your account. For example:
+
+- opening a design, STEP, STL or 3MF file from someone else runs code, or reads or overwrites files
+  it shouldn't
+- a website or another computer can reach or control SolidCraft
+- an agent gets past a prompt that promised to ask you first
+- the web app reaches beyond the page's own storage
+- a release package or an update can be tampered with
+- an API key or token gets sent somewhere it shouldn't go
+
+## What to report as a normal bug
+
+Please [open an issue](https://github.com/tangency-labs/solidcraft/issues/new) for these. They're
+still worth fixing, but they aren't security issues:
+
+- anything that needs a program already running on your computer, or the control token. A program
+  running as you can already do what you can.
+- MCP's allowed folders. They guard against accidents, they aren't a security boundary, and an agent
+  with a shell of its own can already reach those files. Getting around them isn't a vulnerability.
+- crashes, hangs, or heavy memory or CPU use, unless they also lead to something in the list above
+- anything that only happens in an unusual setup you'd have to choose on purpose
+
+## Before you send it
+
+- **Run it.** Reproduce the problem on the latest release. If you only read the code, say so, and
+  expect it to wait.
+- **Check it yourself.** If a scanner or an AI agent found it, read the code and confirm it first.
+  These tools tend to overrate what they find.
+- **Say what's gained.** Name what the attacker needs and what they get. I set the final severity.
+
+Reports that don't fit will be closed with a short note, or moved to the issue tracker.
