chore: mergify - remove invalid speculative checks field #1076
Description
Describe the bug
.github/mergify.yml's queue_rules[0] sets speculative_checks: 1, introduced in #1059. Mergify's current schema rejects this field ("Extra inputs are not permitted @ root -> queue_rules -> item 0 -> speculative_checks"), which makes Mergify's own status checks ("Summary", "Mergify Merge Queue") permanently report failure on every PR.
That failure is enough to keep GitHub's mergeStateStatus at BLOCKED and reject gh pr merge/the merge button with "the base branch policy prohibits the merge" - even when both actually-required status checks (All Checks Passed, validate-pr-template) pass cleanly. Found while trying to merge unrelated PRs #1073 and #1075.
To Reproduce
- Open any PR against
develop - Check the "Summary" or "Mergify Merge Queue" check run's output
- See: "The current Mergify configuration is invalid"
Expected behavior
Mergify's config is valid and its status checks pass (or are simply absent) so they don't block merges.
Additional Context
Fix: remove the unsupported speculative_checks key from queue_rules[0] in .github/mergify.yml.

Fixed by #1077 (merged: 3afe7fd). GitHub's auto-close via the "Closes #1076" reference didn't fire despite correctly recognizing the link (confirmed via the GraphQL
