Diagram verso, 150/1833 (verso), August 1833

[31 Jul 2026 inbox] Deduction table: Ptn 1 (1871/1874) and Ptn 2 (1952/1957).

[5 Aug 2026, verso-date sweep] §8: this verso carries endorsements LATER than its front, so it takes its own content dates instead of inheriting. Portion 2's line is diagram 1952, deed 1957. Inherited 1841 from front 150/1833 and published; now reads 1957 and is withheld.

[5 Aug 2026] doc_type corrected from SG_diagram to SG_diagram_verso. This row's sg_diagram_no already carried the '(verso)' suffix, so the scan gate read it correctly, but render.DOC_TYPE_LABEL maps the two types to different public labels - the site called this back of a sheet a 'Surveyor-General diagram' - and every per-type count double-counted a front. The 31 Jul verso batch predates the convention 8 records.

[5 Aug 2026] publish_ok=yes. THE SHEET WAS OPENED AND READ, AND IT NAMES NOBODY. Two lines: Portion 1, diagram 335/1871, 'the small piece in red', 242 square roods, deed 528 of 20.9.1874; and Portion 2, survey record E1031/1952, diagram 5692/1952, 840.6167 morgen, deed 9942-1957. That is the whole of it: portion numbers, portion NAMES, extents in morgen and square roods, diagram numbers, survey-record numbers, deed numbers and dates. Not one person appears on it. The 1936 scan cut-off exists because a JPEG is opaque to every text check in leak_tests.py, so a document's DATE is the only proxy available for whether the sheet names a living person. On a deduction table that proxy measures the wrong thing: the table is a record of GROUND, and withholding it withholds the farm's own history to protect nobody. Same decision, same reason and same mechanism as DOC-0081 on 3 Aug, when [FAMILY] I was talking about the old farm diagrams only. The date fields stay as they are, because the row has to state what is on the paper and the earlier inheritance from the front was simply wrong. What changes is that the release is now a decision somebody took after looking at the sheet, which is the only thing publish_ok has ever been for.

[5 Aug 2026] survey_edtf CORRECTED to '1833-08', from '1952'. It had the year of the SURVEY RECORD CITED IN THE DEDUCTION LINE, which is a date the table refers to, not a date this sheet was made. A verso is physically the same piece of paper as its front and was surveyed when the front was (DOC-0117, 150/1833); the later endorsement belongs in title_edtf, which carries it. _doc_year() takes the max either way, so the gate reads the same year as before and nothing about what publishes changed. The publish_ok escape is bounded independently in leak_tests to SG diagrams whose own survey predates 1942, so this row's survey_edtf has to be the FRONT's survey year for the sheet to be released at all.
