Forty-Six of Seventy-Nine Looked Untouched
A survey of the corpus asked a simple question: which items have been worked on since they were first published? The answer came back forty-six of seventy-nine untouched. It was wrong. Several of those items had been through three passes in a single week.
Nothing was hidden and nobody was careless. The work happened, the improvements shipped, and none of it was stamped — so from the outside, an item that had been carefully revised three times and an item nobody had opened were the same item. The survey was not measuring work; it was measuring records, and for those items there were none.
Why the Backfill Is Not the Fix
The obvious response is archaeology: reconstruct the history from commits, from coordination rows, from anything you can find. That was done, and it was worth doing, and it taught the actual lesson — reconstruction is expensive, incomplete, and dangerously plausible.
Expensive because each item needs a human reading a commit log and deciding what a change meant. Incomplete because plenty of real work leaves no commit at all — a decision, a rejected approach, a review that found nothing worth changing. And plausible because the reconstruction looks like a record afterward, so the next reader trusts it exactly as much as they would trust the real thing.
Which is why every backfilled entry has to be marked as backfilled, with its evidence attached, and never silently mixed with entries written at work time. Two things that look the same and are not must be labeled, or the label stops being available forever.
What a Stamp Has to Carry
A timestamp and an author are not enough. The entry that turns out to be useful a year later carries what kind of pass this was, who ran it including which system and which harness, what changed, and what the evidence was. The second of those is the field people leave out, and it is the field that makes trend questions answerable: whether output quality shifted with a version change is a query if provenance was recorded, and a forensic dig if it was not.
