 It contains no file contents, no owner names, no repository names and no URLs.
 Every measurement in it is reproducible from the method described below.
 
-One row per instruction FILE INSTANCE that the pipeline has fetched, converted, and RETAINED THE BODY OF. A row is a file, NOT a repository and NOT an owner: one repository commonly contributes many rows, and a widely-forked file appears once per fork. Any count derived from this table is a count of files unless it explicitly de-duplicates. Two exclusions narrow it further: rows whose deterministic security grade is 'fail', and rows the pipeline tracks without a stored body, which cannot be measured and are therefore absent rather than counted as passing. The retained-body requirement is the largest of the three filters, so this is a measurable subset of what we track and not a census of it.
+One row per instruction FILE INSTANCE the pipeline has fetched and converted.

Any count derived from this table is a count of files unless it explicitly de-duplicates. Files whose deterministic security grade is 'fail' are excluded. Each file is measured once, when first seen, and the measurements are retained permanently, so a file stays in the population for every later edition even after we discard its body for storage reasons. Files first crawled before that retention policy began are absent, which makes early editions a floor rather than a census.

+**Early editions are a floor, not a census.** Each file is measured once, when
+first seen, and those measurements are kept permanently. Files first crawled
+before that retention began were never measured and cannot be recovered without
+re-fetching them, so they are missing. Counts will therefore rise across the
+first few editions partly because coverage is filling in, not only because the

 **Security-failing files are excluded.** Rows whose deterministic security grade
 is `fail` were removed before export. The remaining population is therefore
 slightly cleaner than the raw corpus.
