Let a geometry state named numeric columns - #910
Conversation
An optical path could state a value varying along distance only if that value was a CRS position, and a CRS holds at most three axes. Borehole depth where the CRS is spent on easting, northing, and elevation; pipeline chainage; burial depth; fiber azimuth -- all of them fell in the gap, and the only place left for them was annotations, which are a set of intervals rather than a curve and hold no unit. Geometry.coordinates becomes a mapping of column name to values, with a units mapping beside it for the columns which are not axes. Which ones those are is the CRS's to say: a column it declares, or the canonical x/y/z alias of one, is that axis and takes the CRS's units; anything else is a quantity in its own right. A segment states every axis or none of them, so half a position never reaches a reader, and a segment which states no axis at all is now a perfectly ordinary thing to write. Each column is its own function track. Two segments may cover the same distance as long as they do not state the same column over it, which is what lets a borehole depth and a fiber azimuth be surveyed independently. Interpolation, half-open coverage, and the run-end rule are unchanged, and a column never bridges two segments. In a CSV, a header the CRS does not name is such a column and may carry its units in parentheses -- `depth (m)`. Text is refused there, with an error pointing at annotations.csv, which is where a value that varies along the fiber without being a number belongs.

There was a problem hiding this comment.
When two overlapping segments spell the same CRS axes differently—for example, one uses x/y and the other uses easting/northing—the spans are grouped under different raw names, so Inventory.check() accepts both. coordinates_at() then writes both segments into the same canonical axis and whichever segment is iterated last silently wins, making the reported position depend on segment ordering. Canonicalize axis columns through the CRS when checking overlaps.

For a path containing only non-position geometry columns, which is now explicitly legal, coordinates_at() returns an all-NaN array and this wraps it as a defined axis coordinate. Consequently an explicit coords=("x",) bypasses on_missing, while blanket enrichment manufactures all-NaN x/y/z coordinates even though no segment states a position. Return None when no geometry segment declares the requested axis, while retaining NaNs only for uncovered distances of an axis that actually exists.

There was a problem hiding this comment.
When an axis-bearing segment ends exactly where an independent custom-column segment begins, the latter marks that distance as claimed because masks are computed across every geometry segment. The axis segment therefore loses its final control point, and the custom segment is skipped for having no axes, leaving a NaN position at that channel. Build these masks from only the segments that state position axes so unrelated numeric columns cannot alter axis endpoint coverage.

A geometry CSV may legally mix canonical and CRS spellings, such as x,northing for a two-axis easting,northing CRS, because axis_index() maps x to the first axis. This check only intersects headers with the literal CRS labels, so it sees only northing and rejects that complete position as partial; the same geometry constructed through the model passes validation. Determine axis completeness through crs.axis_index() rather than literal label membership.

When select() clips any geometry, model_copy(update=...) skips field validation and stores this ordinary mutable dict instead of the declared FrozenDictType; reverse() repeats the same pattern. Callers can therefore mutate selected.geometry[0].coordinates despite inventory models' immutability contract, changing path metadata in place. Revalidate the geometry or explicitly wrap the mapping in FrozenDict before assigning it.

With overlaps now permitted whenever segments state different columns, two differently named geometry segments can cover the same channel and still pass this per-column check. The public bare geometry coordinate is still projected from each segment's name over its whole interval, so at an overlap _fill_from_intervals() silently leaves whichever name was processed last; selecting or grouping by geometry therefore depends on tuple order. Either disallow such overlaps when the segment names differ or stop exposing a single-valued bare geometry identity for them.

A new geometry column named coupling.medium, geometry.name, or another qualified typed-track name passes this reserved-name set and is advertised by get_names(), but get_coord_values() always dispatches names with those prefixes to the typed track before checking geometry columns. The geometry values are therefore unreachable and may silently resolve to a completely different coordinate. Include the qualified typed-track vocabulary in the reserved column names or reject these collisions during path validation.

If a CSV spells the required optical-distance header as distance (ft), this normalization renames it to distance, allowing _point_rows() to use those values as the geometry's meter-based optical distances while the parsed ft unit is discarded because ordering columns are not gathered into units. The inventory then loads successfully with every geometry interval misplaced by the unit conversion factor. Refuse suffixes that normalize to distance or segment rather than treating them as ordinary numeric columns.

Eight findings, of which two placed the fiber wrongly rather than loudly. A segment stating `x`, `y`, `z` and another stating `longitude`, `latitude`, `elevation` over the same distance are two spellings of one axis, and checking columns by name alone let them both through; the axes are now checked again against what the CRS says they are. A segment stating `x` *and* `longitude` has three distinct axes and passed the partial-position guard, after which whichever spelling the mapping held last won -- both are now refused where the position is assembled, not only where it is checked. The rest: a segment which measures without placing no longer claims the position track's run end, or offers an axis of nan where nothing places the fiber at all; a dotted column name is refused, since that is how a field of a typed track is asked for; select and reverse revalidate rather than copying past the validators, so the columns of a selected segment stay frozen and checked; `distance (m)` beside `distance` is a duplicate rather than a pandas TypeError; and `z` is a column of its own under a CRS which declares only two axes, in a CSV as it already was in the model.
Letting two segments overlap where they state different columns left the bare `geometry` coordinate ambiguous: it is each segment's name over its interval, so a channel covered by a depth survey and an azimuth survey took whichever name the tuple held last, and reversing the tuple changed what `select(geometry=...)` matched. Segments which overlap are two measurements of one stretch of fiber, so they state its name -- both "hole 1" rather than "depth survey" and "azimuth survey". Overlapping segments whose names differ are refused, which leaves the identity single-valued without taking the overlap away.

The validation had grown a helper per finding rather than a function per idea. The path's rules are one function now and the inventory's are another, split where they have to be: the path checks its columns by name, and the CRS-dependent ones can only be checked where the CRS is. Two other duplications went with them. `coordinates_at` and `column_at` each carried their own copy of "interpolate this column, then fill the run end the mask includes from the last control point", which is now one helper. The loader read its headers and then coerced them in two passes over the same columns, which is now one. `column_units` and the separate raise-wrapper around the axis-set rule each had a single caller and are inlined. The prose came down too, mostly by not saying in a field description what the class docstring above it already says.

`coordinates_at` used to return as many columns as the geometry happened to state, so an axis the segments did not reach had to be checked for. It returns one column per axis the CRS declares now, and `axis_index` refuses a label the CRS has no axis for, so the index is always one of those columns and the guard was unreachable -- which is what took project coverage off 100%.

Description
An optical path could state a value varying along distance only when that value was a CRS position, and a CRS holds at most three axes. Borehole depth where the CRS is already spent on easting/northing/elevation, pipeline chainage, burial depth, fiber azimuth — all of them fell in the gap, and the only place left for them was
annotations, which is a set of intervals rather than a curve and carries no units.Geometry.coordinatesbecomes a mapping of column name to values, with aunitsmapping beside it for the columns which are not axes.Which columns are axes is the CRS's to say. A column it declares, or the canonical
x/y/zalias of one, is that position axis and takes the CRS's units. Anything else is a quantity in its own right. Sodepthis an axis in a CRS which declares it and a plain column in one which does not, and no data has to move for that to be true.A segment states every axis or none of them. Half a position is not a position, and deciding what the missing axis meant is not a reader's job. A segment stating no axis at all — the chainage case — is now an ordinary thing to write, and contributes no position rather than a broken one.
Each column is its own function track. Two segments may cover the same distance as long as they do not state the same column over it, which is what lets depth and azimuth be surveyed independently along one hole. Interpolation, half-open coverage, the run-end rule, and
intervalare unchanged, and a column never bridges two segments: distance between them is uncovered, whatever either side holds.Reading and writing
In a CSV, a header the CRS does not name is such a column and may carry its units in parentheses,
depth (m). Text there is refused with an error pointing atannotations.csv— a value which varies along the fiber without being a number is what annotations are for. A unit suffix on an axis header is refused too, since the CRS states the units of its own axes.Enrichment resolves a column after the CRS-label step and before the annotation fallback, so
spool.select(depth=(0, 50)), a blanketenrich(), andget_namesall pick it up with no further work. The value is a point sample at the channel's nominal position; there is no gauge-length averaging, and the docs say so.Signature change
OpticalPath.coordinates_at(distances)becomescoordinates_at(distances, crs). Without the CRS the method cannot tell an axis from a column, and guessing is exactly what this PR removes. It also now raises rather than returning a half-width row when an unchecked path holds a segment stating some axes and not others.v1 exclusions
Stated so they are choices rather than oversights: axes are all-or-none per segment; interpolation is linear only; there is no angular wraparound for azimuth-like columns. FDSN export is not addressed because none exists — the only
fdsnin the inventory module is the prose describing location codes.Not in this PR
Patch.coords_from_df(dascore/proc/coords.py) is the manual version of this projection, and its gap-bridging across missing spans is worth a separate look.This PR is red for a reason that is not in it: #912.
tests/test_autogenerated_doccode/recipes/test_tunnel_inventory.pyfails ondevand therefore here, on everytest_codejob and intest_build_docs.OpticalPathAnnotation.valuedefaults toTrue, and1 == True, so serialization drops a numeric value of1as equal to the default; the document then reloads with a boolean in a numeric group and is refused. The tunnel recipe numbers its boreholes 1, 2, 3, so it has been failing since it merged. #912 fixes that in one place; with it applied, the full suite here is 10,209 passed and 0 failed.Review
