Six failures that survive careful reading — a hallucinated import, a green test that proves nothing, a claim with no command behind it — each caught by a mechanism rather than an attitude, and each ending with the one codex line it writes.

every one of these survives careful reading — that is the entry requirement
None of these is caught by being careful, which is why “review it properly” is not a plan. Each is caught by a mechanism, and each mechanism is one line long — so a codex is not a document somebody sat down to write. It is the transcript of the times you were fooled.
