Merged
Conversation
Adds a pull_request_target workflow that enables squash auto-merge for pull requests opened by fern-api[bot] from an in-repo fern-bot/* branch, and lists it in .fernignore so a regeneration cannot prune it.

Why / Prompt
Fern's SDK regeneration PRs sit open until a human clicks merge; this makes them merge themselves once the required checks pass.

.github/workflows/auto-merge.yml. Onpull_request_targetit approves the PR and runsgh pr merge --auto --squash, for a PR opened byfern-api[bot](user id115122769) from an in-repofern-bot/*branch targeting the default branch. It checks out nothing, which is what makespull_request_targetsafe here.Approvestep is the load-bearing part. GitHub Actions cannot be added as a ruleset bypass actor (422: Actor GitHub Actions integration must be part of the ruleset source or owner organization), so the approval satisfies the required review instead of bypassing it. It counts becausecan_approve_pull_request_reviewsis enabled on this repo — verified..fernignore. Fern reads.fernignorefrom the PR's base branch, so the entry only protects the file once this lands.whopio/whopsdk-typescriptmain(blobd85212244c9b454cac360987a3ffd4957d49e848), which mergedwhopsdk-typescript#74with no human action.lint,test,build,decideall reported on#59(merged, all foursuccess) and on#56(all four report;testis red there for an unrelated reason).
