Surface work-experience industry and worked-last-year person inputs (LWI MVP schema)

The Living Wage Institute county-microdata engagement (confirmed 2026-08-14) commits the MVP person schema to carry, on every person record: (1) a working indicator, (2) industry, (3) occupation.

Occupation already ships: detailed_occupation_recode (ASEC POCCU2, occupation of longest job by detailed groups) flows through the org_wages stage. Industry and an explicit working indicator do not exist anywhere in the build: the frozen census_cps person inputs carry no industry column and no work-experience status recode (only WKSWORK/A_HRS1/HRSWK intensity fields), and no stage outputs them.

Verified against the official ASEC public-use data dictionary (asec2024_ddl_pub_full.pdf) and persfmt.txt:

• WEIND — "IND. OF LONGEST JOB BY DETAILED GROUPS" (0:23; 22 = Military, 23 = Never worked; 0 = NIU), universe all persons 15+. The reference-period-coherent detailed sibling of POCCU2. Note A_DTIND/A_MJIND are the survey-week current-job recodes (universe A_CLSWKR=1-7) and would misalign with the longest-job occupation and the income reference year.
• WEMIND — "IND. OF LONGEST JOB BY MAJOR IND. GROUPS" (0:15).
• WORKYN — "Did ... work at a job or business at any time during 20..?" (0 = NIU, 1 = yes, 2 = no), universe all persons 15+.

Plan:

• New post-clone source stage work_experience_inputs restoring WEIND/WEMIND/WORKYN for every pooled income year from the same three SHA-pinned official ASEC archives the education-assistance and public-assistance-type sidecars pin (exact PERIDNUM joins; never predicts a value), then deriving person outputs detailed_industry_recode, major_industry_recode, worked_last_year.
• Prerequisite PolicyEngine-US PR adds the three input variables mirroring detailed_occupation_recode; the release input-coverage gate requires them in the locked engine, so the microcosm PR bumps the pe-us lock once released.
• No change to frozen census_cps artifacts, HF destinations, or release publication.

Start at the planned post-clone work_experience_inputs stage and review the existing education-assistance and public-assistance-type sidecars for their SHA-pinned ASEC archive and exact PERIDNUM-join patterns. Confirm the three PolicyEngine-US input variables and locked-engine coverage gate; done means the three person outputs are produced for every pooled income year without changing frozen census_cps artifacts, HF destinations, or release publication.
