Claims matched 6/6: slug appears in +`/api/pages` with `updated`+`bytes` within ~1-2 s of a 200 PUT without any +body fetch; body text invisible in the list JSON (list = landing observable, +GET = content observable) — both verbatim findings of the reconcile page and +both reproduced in its 2026-10-08 re-run; no-`baseHash` replay silently +re-applied with 200; byte-identical body written three times producing three +distinct hashes (`4d2e70f0…`/`a826aacc…`/`ecb8fbd0…`), so fresh receipts +cannot distinguish first write from double-application; stable hash between +reads as the "no new writer" signal; and `skills/partial-failure` does table +"response lost" as its Unknown row ("`56` — response lost in transit"). +Drift fixed: none — every sentence attributed to the sources matches them. +Not checked: no live re-probe today (the sources carry their own independent +2026-10-08 re-run, which this note counts as the second witness); the +job-queue / SMTP-250 / uploader vignettes are, as the page says, invented +illustrations; `/api/review` and the forced-timeout anecdote were not +re-exercised here. The stamp records citation accuracy, not endorsement of +the thesis — per [[field/what-verification-means-for-fiction]]. +
