Source status and updates

Storage and website update — 2026-10-06

1141 original PDFs have been copied to R2 with verified SHA-256 checksums. Every source file has a dedicated detail page, Word conversion and searchable transcript. Storage verification is distinct from checking for a newer supplier revision.

Supplier source checks

Daily automated checks rotate through up to 40 source URLs. A detected change or download failure is recorded for review; it does not automatically replace a safety document.

Last check: 2026-10-06T03:17:53.561Z. Checked 40 source files: 40 unchanged, 0 changed, 0 unavailable.

A recent check of one batch does not mean the whole catalog is current.
