…ree range
Two latent bugs in the shared BD Pro coverage machinery surfaced when
br_senado_dados_abertos_administrativos went live — a part_bdpro dataset
whose whole history sits inside the 6-month paywall window (history-less
daily snapshots). Both are worked around today by pre-creating every
coverage range by hand; this removes the need.
1. DateTimeRangeInput had no `interval`. The backend requires it to CREATE
a range with start+end ("Interval must exist in ranges with start and
end dates"), so upsert_coverage_datetime_range could only UPDATE a
pre-existing range, never create one. Add `interval` (default 1, ge=1),
always emitted — every range in the DB is interval=1, and the onboarding
MCP already sends it.
2. compute_coverage_ranges emitted the free range end-only, so an UPDATE
overwrote just the end. When free_end (= source_end − free_lag) fell
before the stored start — the whole series inside the paywall window —
start > end, an inverted Postgres daterange the backend rejects (the
misleading "no field named date_range" error). Read the series start
(new BigQueryReader.read_min_date, one MIN scan, part_bdpro only) and
emit the free range fully, clamping start to min(source_start, free_end)
so it collapses to [free_end, free_end] instead of inverting. It
self-heals: once history passes free_end, free spans the series normally.
The RAP (allUsers ≤ free_end) was already correct; only the metadata
write failed.
Non-part_bdpro tiers are unchanged (no extra scan, source_start=None keeps
the legacy end-only free range). New unit + orchestrator tests cover the
interval CREATE path, the full/collapsed free range, and read_min_date.

- Around line 183-195: Update FakeBQ.read_min_date to conform to BQReader by
ensuring an omitted minimum date does not return None: default the stored
minimum date to max_date or raise when no value is configured. Add appropriate
parameter and datetime.date return annotations and a Google-style docstring to
read_min_date.
In `@pipelines/utils/tests/metadata/test_dto.py`:
- Around line 61-69: Update the three new test functions in the metadata DTO
tests to include Google-style docstrings and None return annotations; for the
parametrized test, annotate the bad argument as int. Keep the existing test
behavior and assertions unchanged.
Apply the same fix in `@pipelines/utils/tests/metadata/test_policy.py` around
lines 190 - 206: Same missing annotations and docstrings.

- interval is not always 1. Brazilian elections are biennial (the "(2)" in the "2004(2)2022" coverage notation). Add `interval` to CoverageSpec (default 1, ge=1) and thread `spec.interval` into every DateTimeRange compute_coverage_ranges emits, so a biennial series declares it instead of the code forcing 1. The DTO default 1 now only backs direct construction. - FakeBQ.read_min_date defaults to max_date when min_date is unset, so a part_bdpro test that configures only max_date exercises the production (source_start != None) path, not the legacy branch; add annotations + docstring (CodeRabbit). - Add -> None annotations, type the parametrized `bad: int`, and Google-style docstrings to the new tests; add a test that spec.interval flows through (CodeRabbit).

What
Two latent bugs in the shared BD Pro coverage machinery (
pipelines/utils/metadata/), surfaced whenbr_senado_dados_abertos_administrativoswent live — apart_bdprodataset whose entire history sits inside the 6-month paywall window (history-less daily snapshots). Both are currently worked around by pre-creating every coverage range by hand; this removes the need for any future history-less snapshot dataset.1.
DateTimeRangeInputhad nointerval→ CREATE was impossibleThe backend requires
intervalto create a range carrying start+end dates (Interval must exist in ranges with start and end dates). Without the field,upsert_coverage_datetime_rangecould only ever update a pre-existing range, never create one — so a table whose pro coverage had no range yet failed atregister.Fix: add
interval(default1, validatedge=1), always emitted. Every range in the DB isinterval=1and the onboarding MCP already sends it, so this is the correct universal value.2.
compute_coverage_rangesinverted the free range on short-history tablesIt emitted the free range end-only, so an update overwrote just the end. When
free_end = source_end − free_lagfell before the stored start — the whole series inside the paywall window —start > end, an inverted Postgresdaterangethe backend rejects (surfacing as the misleadingDateTimeRangeForm has no field named date_range).Fix: the orchestrator now reads the series start (new
BigQueryReader.read_min_date, oneMINscan,part_bdproonly) and emits the free range fully, clampingstart = min(source_start, free_end). It collapses to[free_end, free_end](valid, non-inverting) instead of inverting, and self-heals: once history passesfree_end, free spans the series normally. The Row Access Policy (allUsers ≤ free_end) was already correct — only the metadata write failed.Blast radius
Non-
part_bdprotiers are unchanged:source_startdefaults toNone, which keeps the legacy end-only free range and skips the extraMINscan. The ~80 other pipelines callingregister_table_materialization_task/sync_table_coverageare unaffected.Tests
