Pull the latest changes and resolve the deploy target:

  cd {{repo_root}}
  git pull origin main

Resolve the commit SHA to deploy:
  - If {{commit_sha}} is "HEAD", use the current HEAD of main.
  - Otherwise, verify {{commit_sha}} exists in the repo.

Record the resolved SHA to a temp file so subsequent steps can read it
(each step runs in a separate shell — variables do not persist):
  DEPLOY_SHA=$(git rev-parse {{commit_sha}})
  echo "$DEPLOY_SHA" > /tmp/publish-site-deploy-sha

Check whether the currently deployed SHA (if any) already matches:
  if [ -L {{site_root}} ]; then
    CURRENT=$(cat "$(readlink -f {{site_root}})/.deploy-sha" 2>/dev/null || echo "none")
    if [ "$CURRENT" = "$DEPLOY_SHA" ]; then
      echo "Already deployed at $DEPLOY_SHA — nothing to do."
      echo "NOOP" > /tmp/publish-site-deploy-sha
      Post a comment on the issue noting the no-op, then close the issue
      and stop. Do NOT proceed to subsequent steps.

First, read the deploy SHA from the temp file written by pull-latest.
If it says NOOP, stop — the site is already at the target SHA:
  DEPLOY_SHA=$(cat /tmp/publish-site-deploy-sha)
  [ "$DEPLOY_SHA" = "NOOP" ] && { echo "No-op deploy — skipping."; exit 0; }

Create a timestamped deploy directory and extract site files into it:

  TIMESTAMP=$(date -u '+%Y-%m-%d-%H%M%S')
  TARGET="{{deploy_dir}}/${TIMESTAMP}"
  mkdir -p "$TARGET"

Extract site files from the resolved commit:
  cd {{repo_root}}
  git archive "${DEPLOY_SHA}:{{site_source}}" | tar -x -C "$TARGET"

Write deploy metadata:
  echo "$DEPLOY_SHA" > "$TARGET/.deploy-sha"

Persist TARGET path for subsequent steps:
  echo "$TARGET" > /tmp/publish-site-deploy-target

Verify the extraction produced files:
  ls -la "$TARGET/"
