# ── REDISTRIBUTION IS NOT THE SAME AS "FREE" ─────────────────────────
# This header used to say every item was "public-domain, Creative Commons,
# or explicitly free for redistribution", which conflates two different
# permissions and is misleading for the one that matters commercially:
# CC BY-NC *is* Creative Commons and is NOT redistributable in a product
# Lifescope sells or bundles.
#
# Every entry now carries a `redistribution:` tag:
#
#   clean        PD, CC BY, CC BY-SA. Safe to ship inside a product, a
#                published bundle, or a torrent Lifescope seeds.
#
#                A US GOVERNMENT DOCUMENT IS NOT AUTOMATICALLY CLEAN. Three
#                ways it fails, all found in this manifest by reading the
#                PDFs' own front matter rather than trusting the agency:
#                  · third-party figures licensed to the AGENCY, not to you
#                    (TM 9-237 reprints American Welding Society material;
#                    FM 5-499 reprints Deere & Company, all rights reserved)
#                  · a contractor wrote it, so 17 USC 105 never attached
#                    (Peace Corps ICE titles under contract 79-043-0129)
#                  · a copyright notice a grep cannot see - ED242565's title
#                    page is "(C) VITA, 1976", which no search for the word
#                    "copyright" will ever match
#   local-only   Non-commercial terms. Fine for an END USER to download
#                onto their own box; NOT for us to redistribute.
#   unverified   The licence line is an assertion nobody has substantiated
#                against the document's own copyright page. Treat as
#                local-only until checked.
#
# Counts at time of writing: see docs/1800 §content. The practical effect
# is that a future `--profile clean` fetch can build a bundle that is
# actually shippable, which was not previously possible to determine from
# this file.
#
# Every URL below was verified (HTTP 200 + correct content type) on
# 2026-06-11, EXCEPT the NREL entry — see its note.  Catalog scope follows what comparable offline-knowledge
# builds ship (Project NOMAD, PrepperDisk, Kiwix prepper packs): field
# survival, austere medicine, food production/preservation, water and
# power engineering, emergency comms, open textbooks, civic texts.
