Supersedes #113. Same content, rebased onto current main so it can land cleanly. Submitted from the user's fork to comply with the fork-branch-PR-only policy.

Conflict resolution applied

File Resolution
src/mobilityduck_extension.cpp Took both additions: kept main's SingleTileGetters::RegisterScalarFunctions(loader); block AND added #113's TemporalParquetFunctions::Register(loader); registration on a new line under it. Includes section merged similarly.
test/sql/parquet/temporal_parquet.test Took main's stricter expected-output assertions (Brussels-TZ + numeric round-trips) AND appended #113's new tgeogpoint geodetic round-trip + temporalFooter() KV_METADATA test blocks at the end of the file.

Original PR #113 summary (preserved)

  • temporalFooter() scalar — builds the TemporalParquet JSON metadata blob for KV_METADATA embedding on COPY … TO '*.parquet'. Wired into LoadInternal and CMakeLists.txt.
  • Edge-to-cloud quickstartexamples/quickstart/quickstart.sql (5 synthetic North Sea vessels, full pipeline, < 1 s on a laptop), examples/quickstart/quickstart_mobilitydb.sql (bit-identical MobilityDB run for two-platform proof), examples/generic-ingest/generic_ingest.sql (parameterised CSV → TemporalParquet template).
  • SRID + geodetic mismatch fix in the 12 (GEOMETRY, temporal) direction spatial predicate functions:
    • Root cause 1: hardcoded int32_t srid = 0 before deserializing tgeom. Fix: deserialize tgeom first, then srid = tspatial_srid(tgeom).
    • Root cause 2: flipping FLAGS_SET_GEODETIC on the GSERIALIZED directly corrupts the bbox layout. Fix: call geom_to_geog(gs) (public MEOS API) to rebuild the GSERIALIZED with proper 3D bbox + GEODETIC=1, then free the planar copy.
  • tgeogpoint regression teststest/sql/tgeogpoint.test: type constructors, length(), speed(), eIntersects(geom, tgeogpoint) with real geodetic values, plus the SRID/geodetic fix cases.
  • TZ-neutral test policy docdocs/testing-tz-neutral-policy.md.

Why this unblocks 100% parity

The geodetic-mismatch fix in the 12 (GEOMETRY, temporal) direction spatial predicate functions is the binding-side counterpart to the MEOS-C fixes already landing upstream (MobilityDB #1090 / #1092 / #1094). Together they make geodetic spatial relationships work end-to-end through DuckDB, removing the last C-side blocker the prior session flagged in the mobilityduck-geodetic-not-viable analysis (verdict now: feasible).

…eogpoint tests

Adds the user-facing entry point for the edge-to-cloud pipeline plus a
documentation/testing surface around it:

- examples/quickstart/quickstart.sql — 5-vessel synthetic ingest →
  Parquet → Spark-readable layer.
- examples/generic-ingest/generic_ingest.sql — generic CSV → tgeompoint
  ingest template.
- temporalFooter() — builds the TemporalParquet KV_METADATA JSON to
  embed at write time (tgeompoint encoding manifest, schema version,
  timestamp range, SRID).
- SRID/geodetic mixin fix in tgeompoint_functions.cpp — preserves the
  source SRID through cast/transform paths and forces geodetic when
  the input is geographic.
- docs/beta-testing-edge-to-cloud.md — beta-testing guide.
- docs/testing-tz-neutral-policy.md — ecosystem-wide timezone-neutral
  test policy (canonical reference for MobilityDB / MobilityDuck /
  PyMEOS / JMEOS / meos-rs).
- docs/tgeogpoint-design.md — design notes.
- test/sql/tgeogpoint.test, test/sql/parquet/temporal_parquet.test —
  test coverage for the new pieces.
- .gitignore + CMakeLists.txt + extension load — wiring.

The Linux arm64 build failure here ('MeosType' does not name a type) is a pre-existing main-branch bug in src/include/tydef.hpp affecting every PR. Diagnosed + 1-line fix opened as #161. Once that lands, this PR's Linux arm64 build will go green automatically.

`meosType` (lower-case) is the **pre-consolidation** MEOS type name;
`MeosType` (upper-case) is the **post-consolidation** target that the
upstream rename sweep has not yet reached.  The current vcpkg pin
(`vcpkg_ports/meos/portfile.cmake` REF f11b7443ee98…) is still
pre-consolidation: `meos/include/temporal/meos_catalog.h` line 121
declares the typedef as `} meosType;` and every MEOS API uses the
lower-case spelling.  MobilityDuck's source code consistently uses
`meosType` to match — `grep -rn '\bMeosType\b' src/` finds the name
only on the alias line and its comment, nowhere else.

c8cad6d added `using meosType = MeosType;` as a forward-looking
bridge for the eventual consolidation bump.  That bridge points at
`MeosType`, which the current pin does NOT yet expose, so it
breaks every PR's Linux arm64 build with:

  /duckdb_build_dir/src/include/tydef.hpp:18:18:
    error: ‘MeosType’ does not name a type; did you mean ‘meosType’?

The fix is to drop the premature alias and replace the misleading
comment with one that documents the pre/post-consolidation distinction
and the resume path for the next pin bump — at that point a reviewer
can either restore the bridge (this time it'll be valid because
`MeosType` will exist) or sweep the MobilityDuck source from
`meosType` to `MeosType` in a single PR.

Unblocks every in-flight PR's Linux arm64 build: MobilityDB#126, MobilityDB#130, MobilityDB#149,
MobilityDB#158, MobilityDB#159, MobilityDB#160, plus the entire `feat/*_port_core` extended-type
stack (MobilityDB#148/MobilityDB#150/MobilityDB#151/MobilityDB#153/MobilityDB#155/MobilityDB#156).

Reviewer's quickstart — ~10 minutes

What this PR does in one sentence: delivers the edge-to-cloud user-facing surface (3 examples + temporalFooter() for TemporalParquet metadata), plus root-cause-fixes the SRID + geodetic mismatch in the 12 (GEOMETRY, temporal) direction spatial-rel functions that was preventing geodetic queries from working end-to-end through DuckDB.

Files to read (2 hot, others are pure additions):

File What changed Why
src/geo/tgeompoint_functions.cpp Root-cause fixes the SRID+geodetic mismatch in 12 spatial-rel functions Was: int32_t srid = 0 before deserializing tgeom (loses the source SRID) + FLAGS_SET_GEODETIC on the GSERIALIZED directly (corrupts bbox layout). Now: deserialize first then tspatial_srid(tgeom) + use the public MEOS API geom_to_geog(gs) (mirrors PostGIS's implicit cast).
src/temporal/temporal_parquet.cpp (new) Implements temporalFooter(MAP<VARCHAR,VARCHAR>) → VARCHAR Returns the TemporalParquet KV_METADATA JSON for COPY … TO '*.parquet' embedding

Additive (read for context, not concern):

  • examples/quickstart/quickstart.sql — 5-vessel synthetic North Sea pipeline (full edge-to-cloud quickstart)
  • examples/quickstart/quickstart_mobilitydb.sql — bit-identical mirror against MobilityDB (two-platform proof)
  • examples/generic-ingest/generic_ingest.sql — parameterised CSV → tgeompoint template
  • test/sql/tgeogpoint.test — 12 cases covering type constructors, length, speed, eIntersects, the SRID/geodetic fix cases

Smoke verification:

# Geodetic length: Brussels→Liège ~89.5 km
duckdb -c "LOAD mobilityduck; SELECT length(tgeogpoint '[POINT(4.35 50.85)@2026-01-01, POINT(5.57 50.63)@2026-01-01 02:00:00]') / 1000;"
# Expected: ~89.5

Cross-link: depends on #161 for the Linux arm64 build (MeosType alias bug). Once #161 lands, this rebuilds clean.

Why it's safe to merge: SRID/geodetic fix preserves source SRID through cast paths (was silently dropping it); geom_to_geog is the documented MEOS conversion (no internal-state poking). temporalFooter is a new symbol — additive.

…MobilityDB#136)

Cherry-picked from open PR MobilityDB#136 (commit 9e1d7a6) so this PR's CI goes
green before MobilityDB#136 lands. When MobilityDB#136 reaches main, the rebase will
collapse this commit to a no-op and it will drop out.

--- original commit body ---
Pre-stage icu extension for amd64 docker tests

LoadInternal calls ExtensionHelper::AutoLoadExtension(db, "icu") so the
Europe/Brussels timezone option is honoured. Inside the linux_amd64 test
docker container there is no network egress and the local extension
directory is empty, so the autoload fails. Copy the icu.duckdb_extension
that was just built locally (declared in extension_config.cmake) into the
expected path before running the unittester.
…en PR MobilityDB#140)

On macOS LP64 and Wasm/emscripten, int64 (long) and int64_t (long long) are
the same width but distinct types, so clang rejects passing bigint_to_set
where a Set *(*)(int64_t) is expected as a non-type template arg. Cherry-
picked from open PR MobilityDB#140 (a8b1755) so this PR goes green on osx_amd64,
osx_arm64, and wasm_mvp before MobilityDB#140 lands. The cast is a no-op on Linux,
where int64 and int64_t are both long. When MobilityDB#140 reaches main the rebase
collapses this commit to a no-op.
…ion init)

MobilityDuck initializes MEOS with `meos_initialize_timezone("Europe/Brussels")`
in the extension entry point.  tgeogpoint.test had four assertions hardcoded
to `+00` (UTC) instead of `+01` (Brussels winter), so they failed on every CI
runner.

The four affected assertions are all winter-date constructors that go
through `to_timestamp(unix_seconds)` — those parse as UTC then display in
the extension's runtime TZ (Brussels = UTC+1 in January, no DST).  Updates:

  - asText(TGEOGPOINT(...))              -> POINT(...)@2000-01-01 01:00:00+01
  - asEWKT(TGEOGPOINT(...))              -> SRID=4326;POINT(...)@... 01:00:00+01
  - asText(tgeogpointSeq(ARRAY[..., ...])) -> [POINT(...)@... 01:00:00+01, ...]

A fifth literal-constructor case (`tgeogpoint 'SRID=4326;Point(1 2)@2000-01-01'`)
uses the EWKT parser which interprets the literal date as a Brussels-TZ
local time, so it stays at `00:00:00+01` (not 01:00:00+01).

The header comment now documents the Brussels TZ assumption + cross-refs
docs/testing-tz-neutral-policy.md so future test authors don't repeat
this.
…spatch

DuckDB function resolution treats GEOMETRY, TGEOMPOINT, TGEOGPOINT,
TGEOMETRY, TGEOGRAPHY as alias-equivalent because each is a
LogicalType::BLOB with an alias label. The constant-folder routes
eIntersects(GEOMETRY, TGEOGPOINT) into the {TGEOMPOINT, GEOMETRY}
overload of TgeoGeoIntExec from src/geo/tgeometry_ops.cpp (earlier
registered), which assumes args.data[0] is the Temporal and feeds
the GEOMETRY blob to tspatial_srid — hitting ensure_tspatial_type
inside MEOS with 'must be a spatiotemporal value' before any of the
correctly-direction-aware *_geo_tgeo executors get a chance to run.

Add BlobLooksLikeTemporal to geo_util.hpp: a pure-predicate probe
that reads byte 4 of the blob (Temporal's temptype field) and runs
it through tspatial_type — true only for T_TGEOMPOINT / T_TGEOGPOINT
/ T_TGEOMETRY / T_TGEOGRAPHY / T_TRGEOMETRY. DuckDB GEOMETRY blobs
have byte 4 in their WKB header which never matches one of those
MeosType enum values.

Use the probe at the top of TgeoGeoIntExec in all three *_ops.cpp
TUs to detect mis-ordered args and silently swap roles before
decoding. Also extend each executor with the geodetic-aware
geom_to_geog conversion (matching the existing pattern in
TgeompointFunctions::Eintersects_*) so the swapped-direction call
still respects MEOS_FLAGS_GET_GEODETIC.

Also fixes a unique_ptr<BinsBindData> -> unique_ptr<FunctionData>
build break in span_table_functions.cpp's BinsBindData::Copy() that
otherwise blocks the substrate fix landing alongside the test.

Locally green: test/sql/* full suite, 60/60 test cases, 1346/1346
assertions (was 1335/1336 with the failing line-56 eIntersects).
gdb-confirmed: BlobLooksLikeTemporal probe returns a_is_temp=0
b_is_temp=1 for the (GEOMETRY, TGEOGPOINT) case, swap routes
TGEOGPOINT to the Temporal path.

`meosType` (lower-case) is the **pre-consolidation** MEOS type name;
`MeosType` (upper-case) is the **post-consolidation** target that the
upstream rename sweep has not yet reached.  The current vcpkg pin
(`vcpkg_ports/meos/portfile.cmake` REF f11b7443ee98…) is still
pre-consolidation: `meos/include/temporal/meos_catalog.h` line 121
declares the typedef as `} meosType;` and every MEOS API uses the
lower-case spelling.  MobilityDuck's source code consistently uses
`meosType` to match — `grep -rn '\bMeosType\b' src/` finds the name
only on the alias line and its comment, nowhere else.

c8cad6d added `using meosType = MeosType;` as a forward-looking
bridge for the eventual consolidation bump.  That bridge points at
`MeosType`, which the current pin does NOT yet expose, so it
breaks every PR's Linux arm64 build with:

  /duckdb_build_dir/src/include/tydef.hpp:18:18:
    error: ‘MeosType’ does not name a type; did you mean ‘meosType’?

The fix is to drop the premature alias and replace the misleading
comment with one that documents the pre/post-consolidation distinction
and the resume path for the next pin bump — at that point a reviewer
can either restore the bridge (this time it'll be valid because
`MeosType` will exist) or sweep the MobilityDuck source from
`meosType` to `MeosType` in a single PR.

The stage_icu helper mapped only the Linux uname values, so on the
macOS arm64 test runner uname -m returned "arm64" and the icu
extension was copied to .duckdb/extensions/v1.4.4/arm64 instead of
.../osx_arm64, where DuckDB's autoload looks. The hub fallback is not
reliably resolvable on that runner, so the osx_arm64 Test step failed
to load the extension. Map the OS and architecture to the DuckDB
platform string (linux_amd64, linux_arm64, osx_amd64, osx_arm64) so
the locally built icu is staged at the path autoload expects on every
tested platform; the Linux mapping is unchanged.
