On first run, push_repo_memory generates 5 GitHub Actions error annotations from git fetch and git pull failures that are entirely expected — the memory branch simply doesn't exist yet. These show up as real errors in the annotations UI, causing confusion.

Root cause

execGitSync unconditionally calls core.error(...) on any non-zero git exit, even when the caller catches and handles the failure. That produces GitHub Actions annotations regardless of whether the failure was anticipated.

Changes

• git_helpers.cjs — Added suppressLogs option to execGitSync. When true, non-zero exit-status failure details are routed to core.debug instead of core.error, suppressing annotations while preserving debuggability. Spawn-level errors (result.error, e.g. ENOENT/EACCES) always use core.error regardless of suppressLogs since those are unexpected system failures. Removed unnecessary typeof core !== "undefined" guards — core is always available via shim.cjs. The option is destructured out before spreading into spawnSync to avoid passing an unknown option to it.

  // Before: always called core.error on failure → annotations
  execGitSync(["fetch", repoUrl, `${branchName}:${branchName}`], { stdio: "pipe" });
  
  // After: expected failure, no annotation
  execGitSync(["fetch", repoUrl, `${branchName}:${branchName}`], { stdio: "pipe", suppressLogs: true });

• push_repo_memory.cjs — Applied suppressLogs: true to three call sites where failure is expected:

  • sparse-checkout disable (no-op when sparse checkout isn't active)
  • git fetch for branch existence probe (fails on first run)
  • git pull before push (fails on first run when branch doesn't exist)
  • Downgraded the "Pull failed" core.warning to core.info — it's not a warning, it's normal.

• git_helpers.test.cjs — Added tests verifying suppressLogs: true prevents core.error calls (for non-zero exits) and routes details to core.debug instead. Added a beforeEach/afterEach that provides a minimal core stub so all tests pass without requiring manual global.core setup.
