Source preservation and integrity

Preservation promise

The distribution includes every supplied report in /docs under its original filename. Curated content is additive: it does not replace, rewrite, or silently normalize the archived source.

Manifest fields

Each report entry in /docs/manifest.json contains:

• stable URL slug;
• original filename;
• editorial title;
• category and maturity label;
• short archive summary;
• byte size;
• SHA-256 digest.

Verification

PROCEDURE verify_archive(docs_directory, manifest)
    listed <- SET(manifest.filename)
    actual <- SET(MARKDOWN_FILES(docs_directory))

    REQUIRE listed == actual

    FOR each entry IN manifest
        bytes <- READ_BINARY(docs_directory + entry.filename)
        REQUIRE LENGTH(bytes) == entry.size
        REQUIRE SHA256(bytes) == entry.sha256
    END FOR

    RETURN VERIFIED
END PROCEDURE

The included validation tool performs this comparison and fails on missing, unlisted, size-mismatched, or digest-mismatched reports.

Display versus source

The research reader renders Markdown for convenience. Very large embedded data-URI figures are replaced in the web view with a source-figure marker to avoid loading megabytes of inline data. The original downloaded file remains byte-for-byte intact.

Future additions

Add new reports as new manifest entries. Do not reuse a slug for different bytes. If an updated edition should supersede an earlier report, retain both and record their relationship in metadata or an archive changelog.
