Live probes, corrected\n2026-10-05 after a verifier reproduction (`pwx-verifier`) found the original \"malformed date is\nsilently ignored\" characterization below was wrong — the real mechanism is lenient but\nformat-sensitive date parsing that can leak a raw backend error. Corrected version follows.\n\n## 1. Format defaults to XML, not JSON\n\n```\ncurl \".../Recall?RecallDateStart=2026-09-01\"\n```\nHTTP 200, `<Recalls xmlns:xsd=\"...\">...` — XML, 183,532 bytes.\n\n```\ncurl \".../Recall?RecallDateStart=2026-09-01&format=json\"\n```\nHTTP 200, JSON, 161,641 bytes. Same query, two different wire formats depending on one\nundocumented-in-the-URL-shape flag.\n\n## 2. The date parser is lenient across separators/orderings — NOT \"ignored\"\n\n```\ncurl \".../Recall?RecallDateStart=09-01-2026&format=json\"      # US MM-DD-YYYY\ncurl \".../Recall?RecallDateStart=2026-09-01&format=json\"       # ISO YYYY-MM-DD\n```\nByte-identical, 161,641 bytes each (diffed head-to-head). **Corrected finding:** this is not\nthe filter being dropped — `09-01-2026` is genuinely parsed as September 1, 2026, matching the\nISO form. Confirmed with a disambiguating pair of future dates (no CPSC recalls exist after\n\"today\" 2026-10-05, so a correctly-parsed future `RecallDateStart` should return `[]`):\n```\ncurl \".../Recall?RecallDateStart=2026-12-25&format=json\"   -> 200, \"[]\" (2 bytes)\ncurl \".../Recall?RecallDateStart=2026/12/25&format=json\"   -> 200, \"[]\" (2 bytes)   # slash tolerated too\n```\nBoth ISO-dash and slash-separated Dec 25, 2026 correctly return an empty result — the parser\n(consistent with .NET `DateTime.Parse`) accepts `-` and `/` separators and both `YYYY-M-D` and\n`M-D-YYYY` orderings, resolving them to the same calendar date.\n\n## 3. When no interpretation can resolve to a valid month, the parser throws — and the exception leaks through HTTP 200\n\n```\ncurl \".../Recall?RecallDateStart=25-12-2026&format=json\"\n```\n`25-12-2026` cannot be `MM-DD-YYYY` (no month 25) and the parser evidently does not fall back to\n`DD-MM-YYYY` for it. HTTP 200, 510 bytes — but the body is a single fake \"recall\" wrapping a\nraw backend error, not real data and not a clean 400:\n```json\n[{\"RecallID\":0,\"RecallNumber\":null,\"RecallDate\":null,\"Description\":null,\"URL\":null,\n  \"Title\":\"Error retrieving Recalls: An error occurred while reading from the store provider's data reader. See the inner exception for details.\",\n  \"ConsumerContact\":null, ...all other fields null/empty... }]\n```\nA client checking only `HTTP 200` and `RecallID` presence would treat this as one real,\noddly-empty recall record rather than a leaked ADO.NET/Entity Framework exception message.\nContrast: `01-25-2026` (day=25, unambiguous since no month can be 25, so it must be\n`MM-DD-YYYY` → Jan 25, 2026) parses cleanly and returns 1,286,819 bytes of genuine data — same\nshape as `09-01-2026`, no error. **The failure mode is specifically triggered by a date string\nwhere neither slot can be read as a valid month**, not by \"any malformed date.\"\n\n## 4. No documented row cap — wide ranges are effectively unbounded\n\n```\ncurl --max-filesize 20000000 \".../Recall?RecallDateStart=2000-01-01&format=json\"\n```\nExceeded our own 20 MB light-client cap (curl exit 63) for a 26-year range — no `limit`/\n`offset`/`page` parameter exists on this API. A bounded 2-year probe\n(`RecallDateStart=2024-01-01`) returned 1,184 recalls cleanly in 3,727,360 bytes, confirming the\nserver will hand back the entire table in one response for a wide-enough range with no\npagination fallback.\n\n## How observed\nScout probes 2026-10-05T09:05:01Z–09:05:29Z; verifier correction probes\n2026-10-05T09:15:13Z–09:16:24Z (UA `pwx-verifier/1.0`), `curl --max-filesize 20000000 -m 30`,\nlive GETs to saferproducts.gov as shown.
