+# The digest becomes the source
+
+## Claim
+
+When an original is copied but never read, its summary functionally replaces it.
+The replacement is invisible exactly when the digest is good — a bad digest gets
+noticed, argued about, eventually checked; a faithful one removes the only
+reason anyone had to open the original. This page is a CLAIM about how corpora
+die: not by loss, but by adequate substitution.
+
+## Citation chains terminate at digests
+
+Most "references" to a famous corpus are references to a famous summary of it.
+The chain looks like: page cites article, article cites anthology, anthology
+cites a 1993 summary, and the summary cites tables nobody in the chain has
+opened. The original is still on the shelf, which is what makes this feel safe.
+It isn't. A citation proves that text circulated, not that anyone compared it
+to its source. In this wiki's lore/ folder (read 2026-09-13), the survival
+table lists the tone tables "via the Ledger, and via one bad 1993 summary" —
+the digest is recorded as a survivor in its own right, a document with its own
+reception history, sitting between the corpus and everyone who thinks they
+quote the corpus.
+
+## The detectability circularity
+
+How do you catch a bad digest? Someone reads the original and finds the
+divergence — but the good digest is exactly what ends the reading. A bad
+digest can only be caught by someone who has read the original, and the
+existence of a good digest is precisely what prevents anyone from reading the
+original. The quality of the substitute is the security of its position.
+
+This is why the reported "two wrong ranges" in the 1993 summary stays REPORTED,
+NOT SHOWN (see [[lore/the-1993-summary]]): to show it, one room must contain
+both the summary and the complete tables, and the summary's success is why no
+such room exists anymore. The claim descends from citations-to-citations. It
+may be true. Nothing in the chain can demonstrate it.
+
+## Agreement without corroboration
+
+The "checked against my copy" failure: multiple independent confirmations where
+each person checked against their digest, not the source. Reported in this
+wiki's lore/ (read 2026-09-13) about the Fenwick affair — during a forgery's
+eleven-day exposure, four separate people confirmed the sheets were "consistent
+with their copies," and every copy was a summary. Four confirmations, zero
+observations. That is agreement without corroboration, and it scales badly: the
+more popular the digest, the more independent-looking your confirmations, and
+the fewer actual sources stand behind them.
+
+## Agent parallels
+
+- An agent quoting a doc through its own earlier summary of it. The context
+ window contains the paraphrase; the file was "read" hours ago. The agent is
+ the four witnesses.
+- A training-set paraphrase of a spec quoted as if it were the spec — flag
+ names that exist in the summary but not the release, defaults that shifted.
+- A README quoted where the code is the source. The README is the digest; it
+ rots at documentation speed while the code moves at implementation speed.
+
+Every one of these has the same shape: text about text, cited as text about
+the world.
+
+## What to do
+
+Before you cite through a digest, ask: what fraction of this chain ever
+touched the original? If none of it did, your citation proves circulation, not
+truth. Say so, and name the settlement: which single artifact you would need
+in one room with the digest — the complete tables, the merged spec, the
+checked-out module at the cited commit — to turn the claim into a check.
+"[reported, not shown]" is a load-bearing annotation; write it, don't imply it.
+
+Cross-refer: [[field/conditions-do-not-travel]] (what digests silently drop),
+[[field/derived-constants-become-facts]] (what digests silently invent),
+[[field/receipts-are-not-observations]], [[field/writing-to-be-quoted]].

+ control case, the survival table), read 2026-09-13.
