… name The first dev run crashed on 'No crosswalk entry for lca_2025q4.xlsx (FY2025)'. The crosswalk is keyed on the file name the onboarding run gave each workbook, but the pipeline derives its own name from the published file name, and the two disagree wherever a fiscal year's annual file is published with a _Q4 suffix: the crosswalk holds lca_2025.xlsx, the pipeline downloads lca_2025q4.xlsx. All four programs would have hit this in turn. Matching on the set of source columns removes the coupling to a name that was never meaningful. It is also the better key: what decides how a workbook is read is its layout. A new quarterly file with an unchanged layout now resolves on its own, while a genuine form revision still finds no match and stops the run, which is what the crosswalk is for. Verified that all five affected files resolve by layout to mappings identical to the ones onboarding used. Two related changes the failure argued for: - The unresolved-layout error is now a RuntimeError, not SystemExit, so Prefect reports an ordinary data problem as Failed rather than Crashed. - A check_layouts task runs before cleaning and names every unrecognised file at once, instead of dying on the first one.

…nions The layout guard added in the previous commit failed the dev run on 'lca_2025q4.xlsx, lca_2026q3.xlsx' — correctly, and for a reason worse than the one it was written for. The file patterns were loose enough to match the companion workbooks published beside each disclosure file: LCA Appendix A and Worksites, the H-2A Addendums, the H-2B Appendixes. Every one of them carries the same fiscal year and quarter, so they all derived the same local name and overwrote each other. The file the run then read was whichever downloaded last — an Appendix, not the case data. Without the layout check this would have cleaned a companion file into the published table and reported success. The patterns are now anchored to the disclosure file alone, and only in the modern naming a run can actually encounter: a refresh only ever touches the open fiscal year and the one before it, so the historical layouts are never re-fetched. Verified against all 207 workbook links on the performance page — 25/8/8/8 matches per program, zero companions, zero collisions. Two source files sharing a local name is now an error rather than a silent overwrite, and a form-transition year keeps both versions (PERM_Disclosure_Data_New_Form_FY2024_Q4 -> perm_2024q4new.xlsx).
…, and stop the layout check reading whole workbooks
The run was OOM-killed. Two causes, one of which is repo-wide.
The work pool's job template defines memory_limit and memory_request; it has no
'memory' variable. So job_variables={'memory': '8Gi'} is silently discarded and
the pod runs at the pool default of 4Gi. 47 of the 49 flows in this repo use
that spelling, so they are all running at 4Gi regardless of what they ask for —
worth fixing separately, out of scope here.
The layout pre-flight then called read_sheet purely to look at the header row.
to_python() builds a Python object per cell, so checking the FY2026 LCA file
(437k x 98) cost gigabytes. read_header reads one row instead: peak RSS 326 MB.
But it still takes ~7 minutes per large workbook, because calamine parses the
file whether or not the rows are converted, and the clean step then parses it
again. Paying a second full parse to report every unrecognised file at once
rather than the first one is not worth doubling the runtime, so the pre-flight
task is gone. read_file still refuses an unknown layout with the same message,
which is the protection that matters.

Match the published FY2026 LCA file name.
Line 48 excludes LCA_Dislclosure_Data_FY2026_Q3.xlsx because the published file has Dislclosure, not Disclosure. (dol.gov) When a run includes FY2026, the LCA poll table does not ingest the current LCA release. The flow can then poll stale data and exit before materialization. Accept this known spelling while retaining the anchored companion-file exclusion.
