📝 WalkthroughSummary by CodeRabbit
WalkthroughThe pull request hardens static deployment workflows. It changes pull request triggers, consolidates preview builds, validates lockfiles, isolates package credentials, validates Discord metadata, and adds automated boundary checks. ChangesStatic deployment hardening
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The PR changes pull-request execution to pull_request_target, but inconsistent event guards can skip preview, cleanup, and notification jobs and leave active previews uncancelled. Production notifications also accept untrusted marker comments, creating a bounded risk of redirection or suppression. Merge should wait for the trigger mismatch to be corrected or explicitly accepted, with notification validation tracked by the owner. Sequence Diagram(s)sequenceDiagram

In @.github/workflows/deploy-static-website.yaml:
- Line 132: Add self-hosted-k8s to the repository actionlint configuration’s
allowed custom runner labels, covering the runs-on values used by the workflow.
Preserve the existing workflow runner settings and configuration entries.
- Around line 342-349: Update the deploy notification job to also depend on
build, and set its status from build.result when deploy-production is skipped
while preserving deploy-production.result for deployments that run. Keep the
existing push-to-main condition and notification inputs unchanged.
- Line 134: Replace the :latest deployment image references at both jobs using
id-token: write with the approved container image’s immutable `@sha256` digest,
preserving the existing registry image repository and applying the same pinned
digest consistently in both locations.
- Line 69: Restrict the NPM_TOKEN assignment in the build job to trusted
same-repository pull requests and pushes, ensuring fork-controlled workflows
cannot access it during pnpm install or build scripts. Use the workflow’s
existing event context conditions, or replace the secret with a constrained
package-access mechanism.
- Around line 317-330: Set explicit job-level permissions on every Discord
notification workflow caller: use issues: write for pull-request notification
jobs, and use contents: read, pull-requests: read, and issues: read for the
discord-deploy caller. Update the relevant jobs invoking discord-notify.yaml,
including the shown thread-update caller, without changing their existing
conditions or inputs.

In @.github/workflows/deploy-static-website.yaml:
- Around line 363-371: Update the comment lookup around
github.rest.issues.listComments to paginate through all issue comments and
safely handle missing comment.user or comment.body fields before checking the
Bot type and Preview Deployment text. Preserve the existing botComment selection
behavior while preventing duplicate preview comments and runtime errors.
- Around line 92-98: Update the executable dependency source check in “Reject
executable dependency sources” to ignore legitimate workspace link entries such
as importer version: link:... values, while continuing to reject external git,
hosted repository, URL, file, and other disallowed resolution sources. Adjust
the grep pattern or scope without changing the step’s failure behavior for those
external sources.

Earlier caller runs proved hosted policy/build, artifact-only deploy, preview comment, and cleanup paths before final authorization delta. Current exact head proves validation, token isolation, and live reauthorization through hosted CI plus executable exact-shell fixtures. GitHub loads reusable/default-branch workflow definitions for trusted lifecycle events, so full current-head production and
