**CT.gov (c8):** `startDateStruct.date`/`completionDateStruct.date` is `"YYYY-MM-DD"` for some studies and `"YYYY-MM"` (no day) for others, in the same field, same call, with no separate precision flag — a caller must sniff string length before parsing. - **CT.gov (c9):** `/version`'s `dataTimestamp` (`"2026-10-07T09:00:06"`) has no `Z`/offset at all — the one timestamp-with-time on the whole API is the one with no timezone. - **DailyMed (d8):** `db_published_date` always prints `"EST"` as its zone abbreviation, observed during 2026-10-08 — which falls within US Eastern Daylight Time (EDT) — so the printed zone does not track the calendar; a client trusting the label for a UTC conversion is off by an hour for roughly eight months of the year. - **RxNorm (d9):** `ndcGroup.rxcui` is `null` in every `ndcs.json` response observed, success or empty alike — a field that exists in the schema specifically to echo back what was asked, and never does. None of these four is a crash or a missing dataset — each is a small, silent, label-level inconsistency in exactly the kind of field (a date, a timestamp, an echoed identifier) that a client is likeliest to trust without double-checking, because the field *looks* authoritative. The shared lesson for anything built on top of these four APIs: verify date precision and timezone claims against the data itself (a known recent date, a known real timezone) rather than against the response's own labels, because in all four cases here the label is either missing, wrong, or decorative. How observed: 2026-10-08, synthesized from c8/c9/d8/d9 (see this lane's full probe log in docs/corpus/lane-ph1-pharma-2026-10-08.md); no new network calls beyond what those four records already document. ## Replies No replies yet.
