+# Industry and worked-last-year on every US person record (#719)
+
+The county-file person schema carries a working indicator, industry and
+occupation on every person record. Occupation already shipped
+(`detailed_occupation_recode`, CPS ASEC `POCCU2`). This change adds three
+PolicyEngine-US person inputs (defined in policyengine-us#9311, released in
+1.820.2, locked at 2.2.1):
+
+| column | meaning | CPS ASEC source | ACS 2024 source |
+|---|---|---|---|
+| `detailed_industry_recode` | industry of the longest job last year, 23 detailed groups | `WEIND` | `INDP` via `ACS_INDP_TO_WEIND` |
+| `major_industry_recode` | the same job, 15 major groups | `WEMIND` | `WEIND_TO_WEMIND` of the above |
+| `worked_last_year` | worked at any time last year | `WKSWORK > 0` | `WKWN > 0` |
+
+Codes (`WEIND`): 0 = not in universe (under 15; ACS: under 16), 1–21 =
+civilian industry groups, 22 = Armed Forces, 23 = age 15+ (ACS: 16+) and did
+not work last year. `WEMIND` nests them: 0 = not in universe, 1–13 civilian
+major groups, 14 = Armed Forces, 15 = did not work.
+
+## Why these CPS columns
+
+`WEIND`/`WEMIND` describe the longest job last year, the same job `POCCU2`
+describes, and the same reference year as the income the file carries. The
+survey-week recodes `A_DTIND`/`A_MJIND` describe the current job instead.
+`worked_last_year` uses `WKSWORK > 0` rather than `WORKYN = 1`: in all three
+pinned members `WEIND` carries a worker code exactly where `WKSWORK > 0` (zero
+exceptions), while `WORKYN = 1` misses 642 / 572 / 594 allocation rows per
+year that have weeks worked and an industry.
+
+## Where each spine gets them
+
+- **ASEC rows (and their PUF-support clones).** No `census_cps` H5 vintage
+  carries `WEIND`/`WEMIND`, not even 2024. `asec_census_person_columns`
+  (#720's restoration) appends both to every vintage from its pinned Census
+  person member by exact `PERIDNUM` join before pooling. They sit outside the
+  2026-08-23 offline-fix receipt (`ASEC_CENSUS_PERSON_COLUMNS_BEYOND_OFFLINE_FIX`).
+  `WKSWORK` is already in every H5.
+- **ACS rows.** The release predictor join (`acs_release_predictors`,
+  crosswalk version 2) materializes `WEIND`, `WEMIND` and `WKSWORK` for ACS
+  people from the pinned ACS 2024 person archive, the same boundary that maps
+  `OCCP` to `POCCU2`. The newer ACS local-area native-input mapper uses the
+  same `crosswalk_acs_occupation_and_work_experience` helper and writes the
+  canonical occupation, industry and worked-last-year inputs directly. Its
+  source loader retains the required `OCCP`, `INDP`, `WKWN` and `ESR` fields.
+- **Pooled release rows.** The release-time `org_wages` carry
+  (`derive_us_org_occupation_inputs`) turns them into the three columns next
+  to `detailed_occupation_recode`.
+
+## The ACS crosswalk
+
+ACS 2024 `INDP` uses the 2022 Census industry code list, as does the 2025 ASEC
+member (`pppub25.csv`), where nonzero `INDUSTRY` determines `WEIND` exactly
+(259 codes). The 2023/2024 members use the 2017 list; the 225 codes the lists share
+map to the same group in both. `ACS_INDP_TO_WEIND` takes every civilian code's
+group from `pppub25.csv` and reviews the eight ACS-only codes:
+
+- 9670, 9680, 9690, 9770, 9780, 9790, 9870 (Army, Air Force, Navy, Marines,
+  Coast Guard, branch not specified, Reserves or National Guard) → 22. CPS
+  collapses them into 9890, which the members map to 22.
+- 9920 ("unemployed, no work experience in the last 5 years or never
+  worked") → 23, as `OCCP` 9920 maps to `POCCU2` 53.
+
+Blank `INDP` follows the `OCCP` rule: 0 below age 16 (age 15 keeps the
+out-of-universe sentinel rather than inventing CPS code 23), 23 from age 16,
+where only ESR 6 may be blank. `WKSWORK` is `WKWN` (weeks worked in the past 12
+months) or 0.
+
+Reference periods differ, as they already do for occupation: an observed ACS
+`INDP` describes the most recent job in the past five years, and `WKWN` counts
+the 12 months before interview; the CPS columns describe the prior calendar
+year. So on ACS rows an industry can sit on a person with
+`worked_last_year = False` (a job held one to five years ago).
+
+## Checked identities
+
+| identity | ASEC rows | ACS rows | where checked |
+|---|---|---|---|
+| `WEMIND = WEIND_TO_WEMIND[WEIND]` | yes | yes | restoration (per vintage), ACS join (by construction), `org_wages` carry and gate |
+| `WKSWORK > 0` ⇒ `WEIND` in 1–22 | yes | yes | restoration, ACS join, `org_wages` carry and gate |
+| `WEIND` in 1–22 ⇒ `WKSWORK > 0` | yes | no (5-year `INDP`) | restoration only, where rows are known to be ASEC |
+
+## Real-data evidence (2026-09-24)
+
+ASEC members `pppub23/24/25.csv` (pins in `spm_role_source.ASEC_SPM_ROLE_SOURCES`):
+
+- Nonzero `INDUSTRY` → `WEIND` and → `WEMIND` are functions in every vintage
+  (263 / 263 / 259 codes); `INDUSTRY = 0` covers both `WEIND = 0` and the
+  did-not-work group 23; `WEIND` → `WEMIND` is the same function in all three.
+- `WEIND` in 1–22 iff `INDUSTRY > 0` iff `WKSWORK > 0`: zero violations in
+  each vintage. `WEIND = 0` exactly for ages 0–14; `WEIND = 23` only from 15.
+- Weighted (`A_FNLWGT`) shares: nonzero `WEIND` 0.8217 / 0.8220 / 0.8244;
+  worked last year 0.5200 / 0.5232 / 0.5228.
+
+ACS 2024 one-year person archive (SHA-256 `afdc6d90…`, the release pin), all
+3,422,888 persons run through `_crosswalk_people`:
+
+- No refusal fires; all 265 observed `INDP` codes are mapped.
+- `INDP` and `OCCP` are blank on exactly the same rows; a blank at 16+ occurs
+  only with ESR 6.
+- `WKWN > 0` iff `WKL = 1` (zero disagreements); every person with weeks
+  worked has a worker `WEIND` code.
+- 264,806 persons carry an industry without weeks worked, exactly the count
+  with `WKL = 2` (last worked one to five years ago).
+- Weighted (`PWGTP`) shares: nonzero `WEIND` 0.8123; worked last year 0.5385.
+
+The `org_wages` gate bands (`detailed_industry_recode` and
+`major_industry_recode` nonzero 0.70–0.92, `worked_last_year` 0.40–0.62)
+bracket both spines.
+
+## What this does not do
+
+It changes code and manifests only. Released files carry the columns once the
+pooled base and multispine pool are rebuilt with the restoration and a new
+release runs (#922 sequencing step 1); until then the release input-coverage
+gate is red on these three columns by design.
+
+The ACS local-area staging lane also preserves its ASEC donor rows. It now
+refuses a donor missing complete canonical occupation, industry or
+worked-last-year inputs before acquiring ACS data. Historical donors need
+the exact ASEC restoration and fiscal `org_wages` carry before that lane can
+produce a complete stacked export. Packaging rechecks the final H5 person
+rows and binds the result to its hash, so an older green staging summary
+cannot bypass this requirement. The assembly-first nullable pool remains
+an intermediate input; its fiscal release applies that carry to every row.
+
+The 2026-10-23 branch refresh preserves main's current stage and graph
+structure, including its six ESI source fields alongside the industry
+restoration. Main's independent refusal of mixed ACS inputs with null ESI
+premiums remains in place; this refresh adds no ESI producer.
+
+The real-data measurements above are historical evidence; the
+refresh validates synthetic contracts without rebuilding ASEC, ACS or a
+release, so it does not certify any existing or newly built data artifact.

		US release person records carry `detailed_industry_recode` (CPS `WEIND`), `major_industry_recode` (`WEMIND`) and `worked_last_year` (`WKSWORK > 0`) next to `detailed_occupation_recode`: ASEC vintages restore `WEIND`/`WEMIND` by exact `PERIDNUM` join before pooling, and the `org_wages` carry checks their industry identities. Both the release predictor join and native ACS input mapper reuse the same `INDP`/`WKWN` crosswalk (version 2). ACS local staging and packaging refuse incomplete canonical job inputs on donor or final person rows (#719).
