#46 Handle renamed site files in delta deploy

[Anonymous]

Originally created by: TheoV823

Context

The site deploy script performs a delta upload using Git diff against the site-deployed tag. The current diff filter only includes added, copied, and modified files:

_git(['diff', '--name-only', '--diff-filter=ACM', f'{since_sha}..HEAD', '--', ':(top)site/'], SCRIPT_DIR)

This excludes renamed files. A previous deploy issue showed that a rename such as site/demo.html -> site/demo/index.html can be missed by the delta upload, leaving the new path absent from the cPanel host.

Desired improvement

Make delta deploys handle renamed site files safely.

Possible approach:

• Include renamed files in the diff filter, likely --diff-filter=ACMR.
• Ensure the new path in a rename is uploaded.
• Separately consider whether old renamed/deleted paths should be removed from the remote host or left in place intentionally.
• Add a small test or documented manual verification case for site/foo.html -> site/foo/index.html.

Non-goals

• Do not change Mneme core package code.
• Do not change Retriever, Evaluator, benchmark, or governance behavior.
• Do not combine this with WAF, Cloudflare, or cache-rule changes unless strictly necessary.

Acceptance criteria

• Renamed site files are included in delta deploy uploads.
• A rename from a flat HTML page to an extensionless directory route uploads the new index.html.
• Deploy output makes skipped/deleted files clear.
• Existing full deploy behavior remains unchanged.

Priority

Small deployment reliability improvement. Separate from Mneme core and benchmark work.
