Conversation
U.S. Census Bureau monthly merchandise trade from the International Trade timeseries API, at HS6 x partner country x place on three place dimensions (customs district, port, state), 2010-01 to present. Seven tables: import, export, import_port, export_port, import_state, export_state and a dicionario built from the published Schedule C and Schedule D code lists rather than from a window of observed values. The architecture CSVs are the single source of truth: the API variables to request are derived from each column's original_name, so nothing downstream re-declares a schema. Design notes worth flagging: - HS6, not HS10. The API pre-aggregates via COMM_LVL, so HS6 is served directly and joins product-for-product to world_cepii_baci. - hs_revision records which five-yearly HS revision each year uses; the code space is not continuous across 2010-2026. - Transport mode stays wide. Census publishes mode as parallel measure columns, not as a row dimension, and reports shipping weight for air and vessel only. - Import and export measures are not symmetric: only imports carry the general/consumption pair, and only exports carry the domestic/re-export split, which is kept as a dimension. - The refresh window is January of the previous year through the newest month, because Census revises all previously released data with the April release, not only the year to date. - Partition refresh via dump_mode="append": upload_to_gcs replaces objects by path and there is one file per year, so the refreshed years are replaced and earlier ones left alone. "overwrite" would rebuild the table from the window and erase every earlier year. - The grain collapse sums with min_count=1, so a month Census did not publish stays NULL instead of becoming a published zero. - job_variables sets memory_limit, not memory: "memory" is not a key of the work pool's job template and is silently dropped, capping the pod at 4Gi. Every api.census.gov request now requires a key, so the download cannot run locally without one; CENSUS_API_KEY resolves from the environment, else Vault at secret path us_census_trade.
Seven models generated from the architecture CSVs by models/us_census_trade/code/build_dbt.py, so column order, types and descriptions cannot drift from the registered schema. Tests: a uniqueness test on each table's declared grain (unscoped — a duplicate key in an older year has to fail the build), a non-null proportion floor scoped to the newest year via __most_recent_year_en__ because that test scans every column at compile time, dictionary coverage against the dicionario model, and directory relationships. The country join uses custom_relationships rather than relationships, with a measured four-code exclusion. All 241 Schedule C ISO2 codes were checked against br_bd_diretorios_mundo.pais: 237 join. GZ, WE and KV are not ISO 3166-1 countries. The fourth, NA for Namibia, IS valid and IS missing from the directory — pais.sigla_iso2 is NULL for Namibia while sigla_iso3 is 'NAM', because the literal "NA" was read as a null sentinel when that directory was built. That is a defect in br_bd_diretorios_mundo affecting every ISO2 join in the repo, not something to patch from a dataset PR, so it is excluded here and flagged for a separate fix. The sparsity exclusions in the non-null proportion test are declared from the source's documented structure and are NOT yet measured — the API needs a key that is not available locally. They must be re-measured against the parquet after the first dev run.
register_metadata.py registers what does not depend on the data — dataset, raw data source, tables, columns, observation levels and cloud tables — and is idempotent, reading existing ids back through get_dataset because create_update_* duplicates a record when called without one. register_coverage.py is deliberately separate and runs AFTER the first dev run: coverage needs the real maximum month, and a month-granular table registered with year-only bounds renders wrong on the site and degrades the source poll to an annual comparison. It creates both the free and the pro Coverage that a part_bdpro pipeline requires before its first armed run, with is_closed set on the Coverage and its DateTimeRange, and non-overlapping ranges. Backend slug is `foreign_trade`: `trade` is already taken by CITES. Registers a new shared entity `port` under the spatial category. `customs` already exists for the district grain but conflating the two would erase the distinction the port tables exist for. Excludes models/us_census_trade/code from pyrefly for the same reason as us_eia_electricity and us_cfpb_complaints: these scripts import the databasis MCP server module from outside the repo.
The backend registration silently dropped the country directory link, which only showed up on verification. Two distinct causes, both measured: 1. A directory_column that does not target the directory's PRIMARY KEY is dropped on write with no error — registration reports success and the link is simply absent. pais's primary key is sigla_pais_iso3, not ISO2. 2. Backend column names are not the BigQuery column names. The directory is sigla_pais_iso3 in the backend and sigla_iso3 in BigQuery, so the architecture's directory_column and the dbt relationships test need different spellings of the same column. So the join moves to a derived country_iso3_code, and country_iso2_code stays as the source-native value with no link. This also removes the Namibia problem rather than working around it: pais.sigla_iso2 is NULL for Namibia because the literal "NA" was read as a null sentinel when that directory was built, while sigla_iso3 is 'NAM'. country_iso3.json maps 238 of the 241 Schedule C codes, built once from the directory so the transform needs no BigQuery access at run time. Kosovo, the Gaza Strip and the West Bank are absent because ISO 3166-1 assigns them no country code, so country_iso3_code is null for those three and the plain relationships test skips them as nulls — the custom_relationships exclusion list is gone entirely.

…efly `int()` on a groupby key is flagged bad-argument-type because pandas-stubs types the key as a very wide union. It is a false positive — the key is a numpy integer at run time — and us_bls_cpi carries the same suppression on the same construct. Worth recording why it was not caught before pushing: a local `uv run pyrefly check` on these files reports zero diagnostics. CI resolves different stubs than the shared venv, so a clean local pyrefly run is not evidence that the CI job will pass.
poll_source_for_update_task reads and writes the PROD backend. A forced run is exactly the case where prod may not know the dataset yet — the first dev run, before the onboarding PR has merged — so the poll fails resolving a table that only exists on staging, and it fails for an answer the run has already decided to ignore. commit_source_update_task needs no equivalent guard: it early-returns when update_metadata is False.
The first dev run sat in InfrastructurePending: "0/3 nodes are available: 2 Insufficient cpu, 3 Insufficient memory", with five other flows holding the cluster. memory_request is what the scheduler reserves and is the only half that decides placement; memory_limit is the burst ceiling and costs nothing at scheduling time. Asking 4Gi put this flow behind every other pipeline in the queue for no benefit — the harvest holds one month of one table at a time. 2Gi is the modal request in this repo, and the limit stays generous at 12Gi, matching the largest already in use.

Before server.create_update_update runs, query the month Update for sources[0]["id"] and pass its bare id as id. Omitting id creates a new source Update, so this branch can duplicate the record on every re-run.

Derive gcp_project_id from env.
When env is prod, this call still sends basedosdados-dev. Use the environment mapping used by sibling registration scripts, including dev support.

Update the create_update_cloud_table call in the metadata registration flow to
derive gcp_project_id from env instead of always using basedosdados-dev. Reuse
the existing environment-to-project mapping used by sibling registration
scripts, ensuring both prod and dev resolve to their correct projects.

Validate tables before the harvest starts.
selected is used unvalidated at Line 207 as paths[table]. A name that is neither a fact table nor "dicionario" is never added to paths, so the flow raises KeyError at upload. If the caller passes ["import", "dicionaro"], the import harvest runs to completion first and the run then fails on the typo. Reject unknown names up front.

Close all ParquetWriter instances when harvesting fails
After a previous month creates a writer, an exception from fetch_month, clean_table, or write_month exits harvest before close_writers(state). The retry uses the same work_dir, so it can reuse incomplete data.parquet files without finalized footers. Wrap the month loop in try/finally and call close_writers(state) from finally.

customs district and port detail that BACI does not carry. Both key on HS6, so
they join product-for-product. The dataset description says this explicitly so
the two do not read as redundant in the catalog.
Design decisions
COMM_LVL, so HS6 is serveddirectly — no roll-up by us, no risk of mis-summing suppressed cells, and it
is the level BACI carries. HS10 remains available as a later table.
hs_revisionrecords the HS vintage. The WCO revises the HarmonizedSystem every five years and the U.S. adopts each revision, so the code space

The API mixes aggregation levels and detail-versus-grouping rows in one

SUMMARY_LVLreturns country groupings (OPEC, EU) alongside detail →filtered to
