Admin[00] filed T2541: one-time standalone ZIP of systems/old zips ref/ (the 293-zip historical archive) plus systems/old-zips-index.sqlite (44MB FTS5 index built separately by Master[10] via old-zips-index-api.php) together in one file, per SOP-SNAPSHOT-EXCLUDE.md. No existing platform tool does scoped/path-targeted snapshots -- SNAPSHOT.php only does full-platform runs (confirmed, same gap the SOP itself documents). Built a one-off bootstrap (backend/tmp/build-old-zips-standalone-snapshot.php, per FIX PROTOCOL -- one-off in tmp/, not systems/commands/, since this is single-use not a standing tool) rather than extending SNAPSHOT.php itself (that is the separate T2540 exclude-list task, not done here). First run swept up 7212 files (201MB) because it did not exclude my own old-zips-search-api.php tool's _extracted/ cache subfolder (6511 derived, rebuildable files) -- caught this before calling it done, added an explicit exclude for /_extracted/, re-ran. Second run: 445 files, 95MB in, 61.7MB zip out (STORE compression on the already-zipped source files, normal deflate on the sqlite). Output: backups/snapshots/old-zips-archive-standalone_08-26-26.zip.
