Description

Two different things in DASCore were called annotations. These ones describe the fiber — intervals of an optical path carrying a group and a value, alongside the geometry and coupling tracks. The annotation sets arriving in #925 describe the data recorded through that fiber. One word for both would have been read as one concept the moment they sat side by side, so the fiber-side ones become labels.

before after
OpticalPathAnnotation OpticalPathLabel
OpticalPath.annotations OpticalPath.labels
annotations.csv labels.csv
AnnotationValue, _annotation_value LabelValue, _label_value
"annotation group" "label group", in prose and in error messages

The table name follows the field name — _TABLES maps a stem onto an attribute of the declared model — so renaming the field renames the file on disk.

A hard rename, with no fallback

A stored inventory declaring object_type: OpticalPathAnnotation, or holding an annotations.csv, no longer loads as one. dev is pre-release and merges to master at release, so this is the window for it.

A table naming no attribute is now skipped, not refused

_merge_tables used to raise for any .csv whose stem named no attribute of the declared type, on the reasoning that such a stem is a typo rather than a new track. That also made an entity directory a place where a crew could not keep its own working spreadsheet, which is not what the format wanted to say. Those files are now left where they lie, the same indifference the loader already shows a photo or a field note.

The other refusal stays: a stem which names a real attribute this format does not read as a table still raises, because that one did claim to be a track.

Skipping everything unrecognised turned out to cost too much, though — it also stopped catching a typo, so a geometrys.csv loaded its directory silently without the geometry it holds. The loader already states the rule that separates the two cases, and it now follows it here as well: strict about near-misses, indifferent to clean misses.

file in an entity directory outcome
crew_notes.csv, names.csv, site_photos.csv ignored
geometrys.csv, couplings.csv, label.csv refused — "Did you mean geometry.csv?"
geometry.csv beside a fiber array refused — "names the track geometry, which FiberArray does not have… a directory too high"
GEOMETRY.CSV refused — case decides nothing here, as it decides nothing for the suffix
annotations.csv refused — "now reads as labels.csv. Rename it: what it holds are labels"

The similarity cutoff is deliberately high, and is measured against the attributes which are actually tables. A loose one, or one ranging over every field, would start reading a crew's own filenames as bad spellings of this format's — which is the refusal the skip exists to end.

A name this format used to read is a third case, with its own message. annotations.csv is neither a typo nor a crew's own file: it was written by this format, for this format, and only this rename made it unreadable. The document doors already refuse the same fact (extra_forbidden on an annotations: key), so ignoring it here would break one stored inventory two different ways — loudly as YAML, silently as a directory, and the silent one loses labels the author believes are in it. _RETIRED_TABLES gives any future rename somewhere to register itself.

What kept the word

Every genuine type annotation: _annotation_members, info.annotation, _is_numeric_annotation, the docs renderer in scripts/, and from __future__ import annotations. The annotation set modules keep it too, since for them it is the right word.

Changelog

  • changed breaking: OpticalPathAnnotation is now OpticalPathLabel, OpticalPath.annotations is now OpticalPath.labels, and an authoring directory's annotations.csv is now labels.csv.
  • changed: a CSV in an entity directory whose name resembles no track is left alone instead of raising, so a crew may keep its own files beside an inventory.
  • fixed: a CSV which nearly names a track, names a track of another entity, or names a track under a different case is refused rather than silently dropped, and says which name it should have.
  • fixed: an annotations.csv left by this rename says what to rename it to, rather than loading the inventory without the labels it holds.

Checklist

I have:

  • filled in the Changelog section above (see docs/contributing/general_guidelines.qmd).

I have (if applicable):

  • referenced the GitHub issue this PR closes.
  • documented the new feature with docstrings and/or appropriate doc page.
  • included tests. See testing guidelines.
  • added the "ready_for_review" tag once the PR is ready to be reviewed.

Two things in DASCore were called annotations and are not the same thing:
these describe the fiber, while an annotation set describes the data
recorded through it. One word for both would have been read as one
concept the moment the annotation store landed beside it.

  OpticalPathAnnotation -> OpticalPathLabel
  OpticalPath.annotations -> OpticalPath.labels
  annotations.csv -> labels.csv
  AnnotationValue -> LabelValue
  "annotation group" -> "label group", in prose and in errors

A hard rename with no fallback: a stored inventory declaring
object_type: OpticalPathAnnotation, or holding an annotations.csv, no
longer loads as one. dev is pre-release and this is the window.

A table whose stem names no attribute is now skipped rather than
refused. The refusal read a crew's own spreadsheet as a typo, and an
entity directory is somewhere a crew keeps working files; a stem which
names a real attribute this format does not read as a table still
raises, because that one did claim to be a track. It also means an
annotations.csv left behind by this rename sits there harmlessly.

Type annotations keep the word throughout.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 Walkthrough

Walkthrough

Changes

The inventory metadata terminology changed from annotations to labels. The public model now exposes OpticalPathLabel and OpticalPath.labels. Loaders use labels.csv, consumers read label groups, and tests and documentation reflect the new names. Unrecognized CSV stems are ignored.

Changes

Optical-path label model and operations

Layer / File(s) Summary
Inventory label model and operations
dascore/core/inventory.py, dascore/utils/intervals.py
The public optical-path model now uses OpticalPathLabel and labels. Validation, selection, reversal, concatenation, serialization, and coordinate discovery use label tracks and label groups.

Label table loading

Layer / File(s) Summary
Label table loading and validation
dascore/core/inventory_loader.py, tests/test_core/test_inventory_loader.py
The loader reads labels.csv, parses label values, directs text geometry to labels, suggests names for near-miss stems, and ignores unrelated or legacy annotation files.

Consumers, examples, and documentation

Layer / File(s) Summary
Label coordinate consumers and examples
dascore/core/_spool_inventory.py, dascore/proc/inventory.py, dascore/core/spool.py, dascore/constants.py, dascore/examples.py, docs/...
Spool inventory, processing code, examples, recipes, tutorials, and notes now refer to label groups and path.labels.

Validation coverage

Layer / File(s) Summary
Label behavior test coverage
tests/test_core/test_inventory.py, tests/test_core/test_spool_inventory.py, tests/test_proc/test_proc_inventory.py, tests/test_inventory_diagrams.py
Tests cover label construction, values, overlap validation, point markers, transformations, serialization, coordinate discovery, loader behavior, and ignored files.

773-790: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Reject the legacy annotations.csv instead of silently dropping it.

For an optical-path directory, _table_stem returns annotations for the old annotations.csv file. Since annotations is no longer a model field, the continue statement skips the file and the inventory loads without its labels. This silently loses stored metadata and conflicts with the hard-rename requirement.

Add an explicit legacy-stem error before the generic unknown-stem skip.

Proposed guard
         stem = _table_stem(child)
+        if stem.casefold() == "annotations" and "labels" in model.model_fields:
+            msg = (
+                f"{_quote(child)} uses the removed 'annotations' table; "
+                "rename it to 'labels.csv'."
+            )
+            raise InvalidInventoryError(msg)
         if stem not in model.model_fields:

Skipping every unrecognised CSV also stopped catching a typo: a
geometrys.csv loaded its directory silently without the geometry it
holds. The two cases are not alike, and this loader already says which
rule tells them apart -- strict about near-misses, indifferent to clean
misses.

A stem close to an attribute of the declared model now raises and names
the one it nearly is; a stem close to nothing is still left where it
lies. The cutoff is high on purpose: a loose one would start reading a
crew's own filenames as bad spellings of this format's, which is the
refusal the skip exists to end.

An annotations.csv left behind by the rename is not close to labels, so
it stays on the ignored side, which is what it was left alone for.
Replacing a noun does not replace the article in front of it: eleven
places read "an label", two of them in errors a user is shown. And the
enrich parameter docs ended up carrying both senses of the word in one
sentence -- a coordinate label the CRS defines beside a label group --
which is the one place the new name genuinely collides with the old
meaning of "label" in this format.
Two blind reviews found holes the green suite did not. The two worst
were both in the near-miss rule added a commit ago:

- A correctly spelled table one directory too high was a clean miss and
  vanished: a geometry.csv beside a fiber array loaded fine and lost the
  geometry, because the rule only consulted the declaring model's own
  fields. A stem which is one of this format's table names now says so
  wherever it sits.
- Case was folded on the suffix and not on the stem, and difflib scores
  GEOMETRY against geometry at 0.000 -- no characters in common -- so
  the one spelling nobody picks for a personal file was the one which
  disappeared, on the platforms whose filesystems do not fold case
  themselves. Both halves fold now.

A name this format used to read is a third case again, and gets a third
message. annotations.csv is not a crew's own file and not a typo: it was
written by this format, and only the rename made it unreadable. The
document doors already refuse the same fact loudly, so shrugging at it
here broke one stored inventory two different ways, silently through the
door the data actually arrives through.

The rest:

- resemblance is measured against the attributes which are tables, so a
  crew's names.csv no longer hard-fails a load with a suggestion the
  loader then refuses on its own terms
- OpticalPathLabel.group still described "the annotated variable", which
  get_summary_df and model_json_schema both publish
- a Python type annotation in the diagram tests had been renamed to
  `label`, in the one module where label already meant a mermaid edge
  label
- eleven test names left half-renamed, which made the suite unsearchable
  for the three senses of the word
- the CRS's coordinate_labels bind to a local `labels` a few lines from
  path.labels in two functions; those locals are now named for the axes
  they hold

And the tests now pin all of it: reverting any of the three guards fails
the suite, where before a cutoff of 0.55 passed it.
