…den partitions Three defects found while auditing MiDES against production BigQuery. 1. 40 of the 49 model files were empty (29 zero-byte) or comment-only (11 containing just `-- update_data`). dbt silently skips the zero-byte ones, but registers the 11 comment-only files as real nodes that compile to `-- update_data` — invalid as `create or replace table X as (...)`, so `dbt run --select world_wb_mides` fails on every one of them. None is referenced by schema.yml or any ref(), and none has ever existed as a table in dev or prod. Removed all 40; the model count drops 1087 -> 1047 and the dataset compiles clean. 2. 36 references hardcoded `basedosdados-staging` instead of going through set_datalake_project — every aux_* lookup plus raw_rsp_mg, raw_empenho_pr and raw_empenho_pb. The macro resolves prod to basedosdados-staging, so prod behaviour is unchanged by construction; what this fixes is the dev target, which was reading *production* staging for those tables and so never compared like with like. Compiled empenho now resolves 34 refs to basedosdados-dev and 2 to basedosdados (the br_bd_diretorios_brasil joins, which are correct as full paths). 3. Partition ranges did not cover the data. Measured against basedosdados.world_wb_mides on 2026-08-24: empenho spans 1989-2024 but declared 1994-2024; liquidacao spans 1992-2024, declared 1995-2024; and pagamento spans 1994-2024 while declared 1996-2022, so DF 2023 and SC 2023-2024 rows land in __UNPARTITIONED__ and lose partition pruning. Widened to latest+5 per the house convention: 1989-2029, 1992-2029, 1994-2029, and the three licitacao tables 2009-2026. No data is rebuilt by this commit; it makes the next materialisation correct.
…able
empenho.sql (101 KB), pagamento.sql (72 KB) and liquidacao.sql (50 KB) were
single chains of per-state CTEs -- 57, 49 and 36 of them -- unioned at the end.
Adding a state meant editing a 2,000-line file, and one state's bad column broke
the table for every state. Each is now a union over ten per-state models under
models/world_wb_mides/states/, and the parents are ~60 lines each.
The CTE dependency graph turned out to be cleanly separable: every state's
transitive closure is disjoint from every other's, with no shared helper CTEs,
so no logic had to be rewritten to split them.
Materialisation is ephemeral, set in dbt_project.yml. The state models inline as
CTEs exactly as before, so the compiled SQL, the published tables and the storage
footprint are all unchanged. Switching to `table` in a non-published schema is a
two-line change there, and is what the per-state pipelines will want so a state
can be rebuilt without touching the rest -- deliberately left for that work,
since it roughly doubles the ~230 GB footprint.
The state models deliberately do NOT project the canonical column list. Column
names come from the first term of the parent union, as they always have, and
several states alias columns differently inside their own CTEs -- empenho_ce
calls one `modalidade_despesa` where the table calls it `elemento_despesa`, and
liquidacao_df calls one `month` where the table calls it `mes`. The union has
always resolved that positionally. Projecting the canonical list per state
looked tidier but changed behaviour, and BigQuery rejected it; the parent keeps
the job. Those aliases are misleading and worth renaming, but not inside a
refactor that is meant to change nothing.
Also drops the `frequencia` CTE from liquidacao and pagamento: defined in both,
referenced by neither (the later `count(1) as frequencia` is a column alias, not
a reference), so it fell outside every state's closure.
Verified three ways:
- static: every CTE body token-identical to its pre-split source, each CTE in
exactly one state, union terms an identical multiset, per file.
- BigQuery dry run: all 30 state models parse and resolve; all three parents
return the same output schema and column names as the pre-split compiled SQL.
- end-to-end: world_wb_mides__empenho_df built against dev matches production
exactly -- 870,042 rows, 870,042 distinct empenhos, sum(valor_final)
309,418,235,890.57 on both sides.
…approve table-approve reads dataset_id off a changed file's parent directory, so any model nested one level deeper yields the subdirectory name as the dataset. For the per-state models this repo now has under models/world_wb_mides/states/, that means launching a materialization flow for a dataset literally called `states` -- 30 of them -- and the loop raises on the first failure, which can abort before the real tables build. Simulated against the MiDES branch: 36 flow runs under the old rule, 6 under the new one. Restricting to depth 3 also fixes a latent case already in the tree: models/br_inpe_queimadas/code/microdados_old/br_inpe_queimadas__microdados_old.sql would parse as dataset_id `microdados_old`. All 1046 real models sit at models/<dataset_id>/<model>.sql, so nothing that should materialize stops materializing. A subdirectory under a dataset holds intermediate models with no table of their own (the ephemeral per-state models compile into their parent) or archived SQL kept for reference -- neither is a published table. This is the same class of exclusion the function already applies to macros/, tests-dbt/ and analysis/. Committed with SKIP=pyrefly-check: that hook fails identically on untouched files in a git worktree, because the worktree lives under .claude/ and its include pattern therefore matches no Python files. Unrelated to this change.

…leanup # Conflicts: # dbt_project.yml
TO's raw data has sat in gs://basedosdados-dev/staging/world_wb_mides/ since
May 2024 -- 9.0 GB across three tables, 2013-2022, all 139 TO municipalities --
with no dbt model, so it reached neither dev nor prod despite the MiDES
documentation site listing the state as covered. This is the first of the five
staged-but-unmodelled states.
TCE-TO publishes a movement ledger: one row per movement on an empenho,
liquidacao or pagamento, signed by `sinal` ('+' issue, '-' anulacao). The MiDES
schema wants one row per line with the movements folded into valor_inicial /
valor_anulacao / valor_final, so each model aggregates by sinal to its line key.
Emitting one row per movement would have put anulacao amounts into
valor_inicial.
The line key is (municipio, orgao, numero, ..., rubrica), not the document
number alone. Of the 238,192 empenho numbers carrying more than one '+' row,
228,729 (96%) differ in `rubrica` -- separate budget lines of one empenho, not
reforcos. Keying on the number alone would merge distinct lines and attribute
each line's anulacao to all of them.
Three source-driven decisions worth recording:
- **modalidade_licitacao is remapped, not passed through.** TCE-TO's codes do
not match the MiDES dictionary -- TO 1 = Dispensa where MiDES 1 = Convite --
so passing them through would have silently corrupted the column for every TO
row. Mapped by description onto world_wb_mides.dicionario. TO's "Registro de
Preco" is a procedure with no MiDES modality, and becomes 98 (Processo
licitatorio) rather than 99 (Outros/Nao aplicavel), which would assert no
tender took place.
- **indicador_restos_pagar is null.** nr_empenho carries the same year as
`exercicio` in all 5,418,514 source rows, so a prior-year empenho is not
identifiable. Checked rather than assumed.
- **nome_credor / documento_credor on pagamento are joined from the empenho**,
which is the only TO table carrying a creditor; supplier identity is one of
the things MiDES exists to expose. Withheld where an empenho names more than
one creditor across its lines, so a payment is never attributed to the wrong
supplier. liquidacao's `credor` is left out of nome_responsavel on purpose:
that column means the official who certified the liquidacao, not the supplier.
Verified against the raw source -- every table reconciles to the cent:
empenho 4,958,414 rows sum(valor_final) 46,822,295,283.38
liquidacao 7,930,599 rows 52,527,362,902.67
pagamento 8,385,628 rows 45,132,810,266.83
each equal to raw sum('+') - sum('-'), across 139/139 municipalities and
2013-2022. All 139 municipality codes resolve against
br_bd_diretorios_brasil.municipio with no orphans, so the schema.yml FK tests
hold. Parent column contracts are unchanged (25/20/25).
Known imprecision, inherent to the source rather than the model: id_liquidacao_bd
is withheld on 14.6% of rows and id_pagamento_bd on 19.1%, because one document
number covers several budget lines and the key is genuinely ambiguous. Two
liquidacao rows out of 7.9M have an unparseable date and land with a null date.

Duplicate 'R' branch makes '29' unreachable.
Line 24 maps tipo_processo_licitatorio = 'R' to '2'. Line 30 repeats the same predicate and can never match, so '29' is never produced. If the second branch belongs to a different source code, correct the literal. If '2' is correct, delete lines 30-31.
The split is byte-identical by design, so this is carried over from the monolithic model. Confirm the intended mapping before the rebuild, because the table-approve label rebuilds empenho.
Proposed cleanup if '2' is correct

BigQuery duplicate column names query result SELECT * CTE official documentation
💡 Result:
In Google BigQuery, duplicate column names are not supported in a query result [1]. If a SELECT * statement (or any query) produces duplicate column names, the query will fail with an error [2][3]. This rule applies regardless of whether the columns originate from joined tables or within a Common Table Expression (CTE) [4]. To resolve or avoid this issue, you can use the following approaches: 1. Use SELECT * EXCEPT: You can exclude specific duplicate columns from one of the sources [5][2][6]. SELECT t1., t2. EXCEPT (duplicate_column_name) FROM table1 AS t1 JOIN table2 AS t2 ON... 2. Select as Records: Instead of selecting individual columns, you can select the table aliases themselves, which returns the data as STRUCT objects [2][7][8]. SELECT t1, t2 FROM table1 AS t1 JOIN table2 AS t2 ON... 3. Use Aliases: Explicitly name and alias all columns to ensure uniqueness in the output [3]. SELECT t1.id AS t1_id, t2.id AS t2_id FROM table1 AS t1 JOIN table2 AS t2 ON... 4. Use REPLACE: Modify specific columns while selecting the rest of the table [6]. SELECT t1.* REPLACE (column_name AS new_name), t2.* FROM table1 AS t1 JOIN table2 AS t2 ON... Note that BigQuery does not automatically prefix or resolve duplicate column names during a SELECT * operation in Standard SQL [8]. Duplicate column names are strictly prohibited, and even variations in casing are treated as identical column names [1].

Rename the 20th projection to valor_final. The model emits valor_inicial twice, and BigQuery rejects the duplicate output name. This preserves the parent model’s positional contract and gives the standalone model unique columns.

BigQuery SAFE.PARSE_DATE prefix behavior documentation
💡 Result:
In Google BigQuery, the SAFE. prefix is a modifier that can be applied to most scalar functions—including PARSE_DATE—to handle runtime errors gracefully [1]. When you use SAFE.PARSE_DATE(format_string, date_string), the function behaves as follows: 1. Error Suppression: If the provided date_string cannot be parsed according to the format_string (or if the result is an impossible date), the function returns NULL instead of throwing a query-halting error [1][2]. 2. Standard Parsing Logic: Aside from the error handling, the underlying parsing logic remains identical to the standard PARSE_DATE function [2]. It requires the date_string to match the format_string [3]. 3. Scope of Effect: The SAFE. prefix only prevents errors generated by the function itself (such as invalid format or out-of-range values) [1]. It does not suppress errors that occur while evaluating the input arguments themselves [1]. Using this prefix is a best practice for processing "messy" data, such as columns containing mixed formats or unexpected non-date strings, as it allows your queries to continue executing rather than failing when encountering a row that does not conform to the expected format [2][4][5].

Aggregate linha_to at the published liquidation grain.
The published world_wb_mides__liquidacao table has no rubrica column. However, linha_to groups by rubrica, while id_liquidacao_bd excludes it. When one liquidation has multiple rubricas, frequencia_to sets id_liquidacao_bd to null for every resulting row. Remove rubrica from the grouping, or change the published schema and identifier contract to retain line-level rubrica data.

The v2 branch publishes empenho identifiers in the id_pagamento_bd and id_pagamento columns.
Positions 14 and 15 of this select list repeat p.id_empenho_bd and p.id_empenho. The parent model applies column names positionally, so those two values land in id_pagamento_bd and id_pagamento. The id_pagamento_bd value that pago_municipio_rj_v2 builds at lines 140-154 is never emitted. Column counts still match, so the union compiles and the defect stays invisible.
Two further points in the same block:
- Line 247 joins
anulacao_municipio_rj_v2, which has one row per(tipoato, id_empenho_bd). One empenho with several cancellation act types duplicates the payment row.valor_anulacaois hardcoded to 0, so the join supplies onlytipoatoforindicador_restos_pagar. - Line 248 joins
frequencia_rj_v2, but no column fromfis selected. Remove the join or use it.
This logic predates the split. Correcting it changes published rows, so confirm the intent before applying the change.

…d pagamento" This reverts commit b3862c0. Backed out at the author's request: adding TO required several judgement calls about how TCE-TO's data maps onto the MiDES schema, and those need a domain review that is not available right now. Shipping them unverified would put choices nobody has checked into a published table. The calls in question, for whoever picks this up: - The source is a movement ledger (one row per movement, signed by `sinal`), aggregated to a line key of (municipio, orgao, numero, ..., rubrica) rather than the document number alone, because 96% of multi-row empenho numbers differ in `rubrica`. - modalidade_licitacao was remapped by description onto the MiDES dictionary, since TO's own codes disagree with it (TO 1 = Dispensa, MiDES 1 = Convite). TO's "Registro de Preco" has no MiDES modality and was mapped to 98. - nome_credor / documento_credor on pagamento were joined from the empenho, TO's only table carrying a creditor. - indicador_restos_pagar was left null because nr_empenho always carries the same year as `exercicio` in this source. The work reconciled to the cent against the raw source (empenho 4,958,414 rows / 46,822,295,283.38; liquidacao 7,930,599 / 52,527,362,902.67; pagamento 8,385,628 / 45,132,810,266.83, each equal to raw sum('+') - sum('-'), 139/139 municipalities FK-clean), so it is recoverable from b3862c0 once the mapping decisions have been reviewed. The rest of the branch is unaffected: the model cleanup, the per-state split and the table-approve depth fix all stand, and the three published tables still carry exactly the ten states they did before.

What this does
Three commits that make MiDES maintainable again, without changing a single published row.
MiDES was last materialised in February 2024 and had drifted: the models no longer ran as a
set, and adding a state meant editing a 2,000-line file. This clears that. It is the groundwork
for adding the five states (ES, GO, RN, RO, TO) whose raw data has sat in
gs://basedosdados-dev/staging/world_wb_mides/since March–May 2024 with no dbt model.1.
fix(world_wb_mides)— remove phantom models, unpin staging project, widen partitions-- update_data.dbt skips a zero-byte file silently but registers a comment-only file as a real node, which
compiles to
-- update_data— invalid ascreate or replace table X as (…). A whole-datasetdbt run --select world_wb_midesfailed on all eleven; only per-model selection worked, whichmatches the two "change to trigger materialization" commits in this model's history. None was
referenced by
schema.ymlor anyref(), and none has ever existed as a table. Model count1087 → 1047.
basedosdados-staginginstead of usingset_datalake_project— everyaux_*lookup plusraw_rsp_mg,raw_empenho_pr,raw_empenho_pb. The macro resolves prod tothat same project, so prod behaviour is unchanged by construction; what this fixes is the dev
target, which was reading production staging and so never compared like with like.
pagamentodeclared1996–2022while its data spans1994–2024, so DF's 2023 rows and SC's 2023–24 rows sit in
__UNPARTITIONED__with no pruning.Widened to latest + 5:
1989–2029,1992–2029,1994–2029, and the threelicitacaotables2009–2026.2.
refactor(world_wb_mides)— one model per state behind each published tableempenho.sql(101 KB),pagamento.sql(72 KB) andliquidacao.sql(50 KB) were single chains ofper-state CTEs — 57, 49 and 36 of them — unioned at the end. Each published table is now a union
over ten models in
models/world_wb_mides/states/.empenhoempenho_rj.sql16 KBliquidacaoliquidacao_sp.sql10 KBpagamentopagamento_sp.sql13 KBThe CTE dependency graph turned out to be cleanly separable — every state's transitive closure is
disjoint, with no shared helpers — so no logic was rewritten. Also drops a dead
frequenciaCTEfrom
liquidacaoandpagamento(defined in both, referenced by neither).Materialisation is ephemeral, set in
dbt_project.yml. The state models inline as CTEs exactlyas before, so compiled SQL, published tables and storage footprint are all unchanged. Switching them
to real tables in a non-published schema is a two-line change there — that is what lets one state
rebuild without touching the rest, and it roughly doubles the ~230 GB footprint, so it belongs with
the per-state pipeline work rather than here.
3.
fix(ci)— only treatmodels/<dataset>/<model>.sqlas a table in table-approveRequired by commit 2.
table-approvereadsdataset_idoff a changed file's parent directory,so a model one level deeper yields the subdirectory name as the dataset. Without this,
merging would launch a materialization flow for a dataset literally called
states, 30 times,and the loop raises on the first failure — potentially aborting before any real table builds.
Simulated against this branch: 36 flow runs under the old rule, 6 under the new one. It also
fixes a latent case already in the tree —
models/br_inpe_queimadas/code/microdados_old/…sqlwould parse asdataset_id = microdados_old.All 1046 real models sit at
models/<dataset_id>/<model>.sql, so nothing that should materializestops materializing.
Verification
The refactor was verified three ways, because this touches a 1.13-billion-row published table:
state, union terms an identical multiset, per file.
parents return the same output schema and column names as the pre-split compiled SQL.
world_wb_mides__empenho_dfbuilt against dev matches production exactly:870,042 rows, 870,042 distinct empenhos,
sum(valor_final)= 309,418,235,890.57 on bothsides.
dbt compile --select world_wb_midesis clean (1077 models);sqlfmt,ruffandyamlfixpass.What merging does
With the
table-approvelabel, merging materialises 6 prod tables:empenho,liquidacao,pagamento,licitacao,licitacao_item,licitacao_participante(~245 GB). That is not a no-op —prod has not been rebuilt since 2024-02-22, and PE's raw staging was refreshed on 2024-05-16, so the
rebuild picks up PE 2021–2023 (+2.6M rows in
empenho, +6.9M inliquidacao). It also appliesthe corrected partition ranges. Without the label, nothing materialises.
orgao_unidade_gestorais untouched here, so SC's 4,197 rows in dev still will not reach prod — thatneeds a separate trigger.
Not in this PR

empenho,liquidacaoandpagamentonow advertise 10 states each insteadof 7, and DF, RJ and SC are discoverable for the first time.
