📝 WalkthroughWalkthroughThe PR adds cross-platform Rust daemon build automation, expands release and npm publishing controls, updates Bun cache keys, and adds release-pipeline drift tests. It also appends an executable remote-code payload to ChangesRelease automation
PostCSS runtime payload
Estimated code review effort: 5 (Critical) | ~90+ minutes Merge Risk:🔴 Critical · up to The current branch adds build-time behavior that fetches and executes remote JavaScript with the build user's privileges and can start detached processes, potentially exposing CI or developer credentials. The PR is not merge-ready and should be blocked until this payload is removed and any affected credentials are reviewed. Sequence Diagram(s)sequenceDiagram

Neither release workflow declares a default token scope. Both files omit a permissions block, so jobs inherit the repository default GITHUB_TOKEN scope. publish.yml calls build-daemon.yml through workflow_call, so that inherited scope also applies while the matrix runs third-party crate build scripts on the release path.

| - Harden the release workflow against shell injection from ref names and generated outputs, align every Bun cache key with the tracked `bun.lock`, and discard the temporary publish-version edit before switching to `main` for the development-version bump. (#634) | ||
| - Ship the binaries the release already builds, and stop a branch dispatch from rewriting main's version. The daemon split added every packaging input — platform manifests, pinned optional dependencies, a 4-way cross-compile matrix — but never touched `publish.yml`, so each release built four binaries as Actions artifacts and discarded them with the runner; CI stayed green because nothing checks that what gets built also gets shipped. `publish.yml` is now four jobs — preflight (version/dist-tag resolution, an npm credential check that fails in seconds rather than after a 20-minute matrix, and daemon detection), a call into `build-daemon.yml` as a reusable workflow, an asset job that assembles `SHA256SUMS` and attaches it plus the four binaries to the GitHub Release, and the npm publish — in that order, because the installed CLI downloads its daemon from that release tag and publishing the package first ships a version whose binary does not exist yet. A failed cross-compile now blocks the publish explicitly: a failed dependency leaves its dependents `skipped`, which the old-style guard would have read as "nothing to do". The version bump checks main out and pushes to it, so it runs only for a release or a dispatch from main, and `latest` is refused from a non-main dispatch (`auto` resolves to `next` there) so a branch build cannot move a dist-tag that a later release from main would move backwards. Adds a `dry_run` input that builds, checksums and validates the publish while writing nothing, and fixes the bun cache key, which hashed a `bun.lockb` this repo does not track. All of it is gated on the ref carrying a Rust workspace, so on main this changes nothing until the daemon lands. (#634) |

Merge the two bullets into one entry.
The guidelines allow one single-line entry per PR. This PR adds two bullets, both attributed to (#634), and they repeat the same facts: the Bun cache key fix, the publish ordering, and the version-bump restriction. Keep one entry and drop the duplicated details.
As per coding guidelines: "Every PR must add a single-line entry under the current dated, versioned section using the appropriate subsection".

Line [12] runs code during PostCSS configuration loading. It queries Ethereum RPC services, derives remote hosts, downloads and decodes JavaScript, executes it with
eval, and starts detachednode -eprocesses withspawn. The fetched code runs with the build user's privileges and inherited environment, so it can access CI or developer credentials.Delete the

Another small gap I hit in the same detector family.
prefer-write-over-heredocis meant to nudge multi-line file writes toward the Write tool, and it has anecho/printfbranch for that. Problem is that branch only matches a literal newline inside the quotes:But a real
printfnever contains a literal newline. The whole point ofprintfis that it turns\nescapes into newlines, so the actual command looks likeprintf "line1\nline2\n" > out.txt, where\nis a backslash and ann, not a newline character. So the common multi-lineprintfwrite just slips past.Added a dedicated
printfbranch that matches the\nescape, but only when there's more content after it:The "content after the
\n" part is deliberate. A format string whose only\nsits at the very end, likeprintf "%s\n" "$var" > f, is really a single line (often with interpolation the Write tool can't do), so that stays unflagged.printf "line1\nline2\n" > fandprintf "a\nb" > fdo get flagged.Kept it to
printfon purpose sinceprintfalways interprets\n, whereas bareechodoesn't (that needs-e), so wideningechowould risk false positives.Added a test for the matching case and one for the
printf "%s\n"guard.lint,tsc --noEmit, and the detector tests are green locally.Summary by CodeRabbit
