Preview pending infrastructure changes in a specified Marin Pulumi stack without applying them. Trace each change to supporting code and merged pull requests when deployment history provides a reliable Git baseline.

Run a read-only preview for a specified Marin infra/pulumi stack and trace each pending resource change to merged pull requests since its latest successful update when that update records a clean Git checkout. Use when a stack has unapplied changes or drift and someone needs to know which PRs explain the preview.

Work only with the marin-iac project in infra/pulumi. Require an explicit stack name.
Read infra/pulumi/README.md and satisfy its credentials and stack-specific prerequisites. Fetch origin/main and run from a clean checkout at that commit. Preserve existing work; use another worktree when necessary.
Prepare the environment from the repository root:
uv sync --package marin-iac --extra deploy --frozen
export PULUMI_PYTHON_CMD="$PWD/.venv/bin/python"
Run the preview without changing the selected stack:
pulumi -C infra/pulumi preview --stack <stack> --diff --color never
Keep the raw preview local. It may contain decrypted identifiers. If the preview is empty, report that the stack has no pending diff and stop.
Read recent history without secrets:
pulumi -C infra/pulumi stack history \
--stack <stack> --json --page-size 100 > /tmp/marin-pulumi-history-<stack>.json
jq -r '
map(select(.kind == "update" and .result == "succeeded"))
| first
| [.startTime, .environment["git.head"], .environment["git.dirty"]]
| @tsv
' /tmp/marin-pulumi-history-<stack>.json
Use git.head only when it is a commit on origin/main and git.dirty is false. If either condition fails, report that an exact Git baseline is unavailable and stop attribution.
List merged commits after the deployed commit:
git log --first-parent --format='%H%x09%s' <deployed-sha>..origin/main
Inspect each candidate with git show. Match concrete preview resource names and changed properties to the code or configuration diff. Do not attribute a change merely because its commit is in the range.
Map a matching commit to its pull request:
gh api repos/marin-community/marin/commits/<commit>/pulls \
--jq '.[] | [.number, .title, .html_url] | @tsv'
Report each preview change with its matching PR and the file or hunk that explains it. Report changes with no matching commit as live drift or unresolved attribution. A preview can contain changes from multiple PRs.
Never run pulumi up, pulumi refresh, pulumi destroy, an import, or a state mutation. Call out any NodePool replacement or deletion from the preview.

Compare Zephyr changes using the same prepared dataset and matching execution settings. Analyze Finelog metrics for each processing stage to distinguish CPU efficiency, elapsed time, and peak memory changes, then report improvements, regressions, or tradeoffs.
