Description

The inventory has been buildable, attachable, and enrichable for four PRs now, and has had no documentation outside docstrings the whole time. This adds the tutorial page.

docs/tutorial/inventory.qmd covers what an inventory is, authoring one as a directory, attaching it to a spool, enriching, conforming, the .inventory name a data directory may carry, and serialization. Every code block runs under the doc-code tests, so the examples are executable rather than illustrative — the proposal site's snippets were explicitly neither.

The .inventory section closes a gap flagged in #897's review: the reserved name was implemented and documented nowhere, unlike its sibling .dascore_index.sqlite3. Both are now documented together in the file IO tutorial.

The model diagrams

Three quarto mermaid blocks: the containment spine, the four independent tracks along an optical path, and the fields which take a resource_id instead of the object.

An earlier version of this PR rendered the model as an interactive cytoscape widget generated from the pydantic models. That cost about nine thousand lines — a spec generator, a lua filter, a front end, and two vendored javascript libraries — to render one page, which is a poor trade for a repository that has to maintain it. Mermaid is built into quarto, ships its own javascript in site_libs, and needs nothing from us.

Generating the spec was the defence against a diagram which quietly stops matching the models, and that property is worth keeping on its own. tests/test_inventory_diagrams.py keeps it for about a hundred lines: it reads the edges back out of the page and checks each against dascore.core.inventory

  • the source names a model,
  • the label names a field that model has,
  • the target names a model that field can actually hold,
  • the edge is dashed exactly where the field accepts a resource_id in place of the object,
  • and every arrow on the page is one the guard could parse, so it cannot go vacuous one unreadable edge at a time.

That last rule is the one the models implement: a field which accepts a str beside a model accepts a resource_id instead of the object, which is what makes it a reference to a shared resource rather than something the object contains. interrogator: Interrogator | str | None refers; networks: tuple[Network, ...] contains.

Seven mutations of the page were checked against the guard, each failing it where the unmutated page passes: renaming a field on an edge, pointing an edge at a class the field cannot hold, drawing a containment edge dashed, drawing a reference edge solid, naming a component class that does not exist, writing an edge in a form the guard cannot parse, and pointing an edge at NoneType.

Review

The page went through six reviewers in parallel, blind to each other: five subagents by lens and Codex as the non-Claude perspective. Most of the 38 findings were against the widget and left with it; the ones against the page stand.

The prose leg executed every code block and checked every claim against the implementation, which is where the page's worst defect surfaced: it said conform_to_inventory drops patches the inventory does not describe, when the default is to raise. Four more claims were wrong in the same direction — confident and untrue — and are fixed.

The test-vacuity leg mutation-tested its findings. Two tutorial examples passed against no-op implementations (the refresh example asserted the same thing twice with nothing edited in between); both now fail when the behaviour they document is removed.

Generating the diagram, while it lasted, was also what found a fiction the proposal site had carried since its first commit: that Station and Channel accept dynamic coordinate fields, so that Station(code="S1", latitude=40.0) works. It does not; the models are extra="forbid" and reject it.

Changelog

  • added: an inventory tutorial covering the DASDAE metadata model, authoring an inventory directory, attaching one to a spool, enrichment, conforming, and the .inventory name a data directory may carry.

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.

Summary by CodeRabbit

  • Documentation
    • Added a comprehensive Inventory tutorial covering creation, validation, attachment, metadata enrichment, selection, splitting, serialization, and archive inventories.
    • Expanded spool documentation with inventory attachment and inventory-based splitting examples.
    • Clarified hidden inventory companion files and linked inventory references from related documentation.
    • Added the Inventory tutorial to the documentation navigation.
  • Chores
    • Excluded locally generated documentation output from version control.
  • Tests
    • Added validation to ensure inventory diagrams accurately reflect supported inventory relationships.

The DASDAE inventory has had no documentation outside docstrings. This
adds the tutorial page and the interactive class diagram the proposal
site used, except that the diagram is generated from the pydantic models
during the documentation build rather than hand-maintained beside them.

Everything mechanical is read from the models: which classes appear,
what fields each has, their types as written, their descriptions, the
first paragraph of each docstring, and the edges between them. Only the
presentation -- color group, which nodes start collapsed, the legend --
is stated by hand, and it is validated against the models on every
build. Generating it immediately found a claim the hand-written spec had
carried since the beginning: that Station and Channel accept dynamic
coordinate fields, which the models forbid.
Two defects were invisible to reading. The filter parsed the spec with
pandoc's markdown reader, whose smart typography rewrote the '...' of all
41 tuple types into an ellipsis -- so the diagram was corrupting the text
it exists to reproduce verbatim. And docs/vendor/elk/LICENSE.md was a
quarto input, so the build published the Eclipse Public License as a
DASCore documentation page, themed and in the sitemap.

The page also said conform_to_inventory drops undescribed patches when it
raises, that selecting on an inventory coordinate never drops a patch,
and that attaching does nothing else when it also clears enrichment.
Four more claims were wrong in the same confident direction.

Two of its examples passed against no-op implementations: the refresh
example asserted the same thing twice with nothing edited in between.
Both now fail when the behaviour they document is removed.

In the generator, _walk_types dropped the resource-id flag when recursing
into a container, _check_nodes let two classes share a drawn name, and
inheritance edges followed direct bases only. Each now has a test which
fails without the fix.

P2 Badge Avoid loading current inventory models in stable-doc builds

When .github/workflows/build_deploy_stable_docs.yaml is manually dispatched before a release containing these inventory models, its Set manual stable docs version step deliberately retains the current scripts while restoring dascore/ from the last stable tag. This eager import then executes the current _inventory_model.py, whose top-level imports require the new inventory classes, so prep_doc_build fails before rendering. The stable workflow needs a tag-compatible generator or must skip this development-only diagram generation.

Declined, having read the workflow. It restores only dascore/ from the tag and keeps the current docs/ and scripts/, so a manual dispatch in the window before the inventory ships is broken whichever way the import falls: docs/tutorial/inventory.qmd's code blocks call dc.inventory and would fail at render, and the API pages and cross references are generated from the current tree too. Moving the import would turn a clear ImportError naming the inventory module in the first step into a render error a thousand pages later. The tag-push path (the normal one) leaves dascore/ alone and is unaffected, and the whole window closes when the inventory is released.

P2 Badge Expose model details without requiring mouse hover

On touch devices and for keyboard-only users, the summaries, fields, types, descriptions, and API links are inaccessible because the tooltip is opened only by Cytoscape's mouseover event; the tap handler solely collapses or expands nodes, and the canvas provides no keyboard interaction or textual fallback. Add a tap/focus-accessible way to open the node details so the diagram's primary documentation is available without a mouse.

Taken in part. A tap now opens the node's details as well as folding it, so the summary, fields and API link are reachable on a touch device; a tap on the background dismisses it. Full keyboard interaction with the canvas is not addressed — the diagram is a supplement to the prose, which carries the same material in text, and getting keyboard navigation of a cytoscape canvas right needs more than a guess.

Fail when a private name survives alias expansion.

_attributes applies the expansions in dict order. If one alias expands to text that contains another private alias name, the remaining private name is printed into the type column, which is exactly what _alias_expansions exists to prevent. A post-check turns that into a build failure instead of a silent documentation defect.

Name the module that actually declares the field in the error message.

The failing test built its pathological class by assigning
__annotations__ after the fact, which since PEP 649 no longer lands in
vars(), so on 3.14 the class carried no annotation at all and the
generator raised AttributeError rather than the TypeError under test.
Built through type() instead, verified against a real 3.14, and the
requirement it was really guarding -- that the models keep their
'from __future__ import annotations' -- is now stated as its own test,
which holds on every version.

From the PR reviews: a private name surviving alias expansion now fails
the build rather than shipping a symbol the reader cannot look up; the
cytoscape load retry is bounded and says so on the page rather than
scheduling timers forever; and a tap opens a node's details, which on a
touch device was otherwise unreachable.
The filter parses the spec through pandoc's metadata reader, so a
backtick or asterisk in a field description is taken as formatting and
dropped on the way to the tooltip. This repo's docstrings use double
backticks freely, so it was a matter of time; the generator now fails
the build and says which text to rewrite.

Also records that a vendored library can relicense between releases, so
an upgrade checks the release's own license files rather than carrying
the old row forward.

The interactive diagram cost the repository about nine thousand lines --
a spec generator, a lua filter, a cytoscape front end, and two vendored
javascript libraries -- to render one page. Three mermaid blocks say the
same three things: the containment spine, the four tracks along an
optical path, and the fields which take a resource_id instead of the
object.

Generating the spec was the defence against diagrams which quietly stop
matching the models. Keep that property without the machinery: the new
test reads the edges back out of the page and checks each one against
the models -- that the source is a model, that the label is a field it
has, that the target is a type that field can hold, and that an edge is
dashed exactly where the field accepts a resource_id in place of the
object.

The prose says that .inventory/ and .inventory.yaml both work. The executable example creates only .inventory.yaml. Add an executable example for .inventory/, or link to the test that covers the directory form.

Three against the guard: it parsed the page at import, so a test run from
an sdist -- which grafts tests but ships only docs/LICENSE -- raised
rather than skipping; an edge line it could not parse was dropped in
silence, which is how a file like this goes vacuous one arrow at a time;
and it checked targets against every leaf type in the annotation, so an
edge drawn to NoneType would have passed.

One against the page: the components track does have to cover the whole
path. It is what gives the path its length, each component tiling the
interval after the last, so the sentence saying no track need cover the
whole path was true of the other three and false of that one.

82-92: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Preserve the inherited reference context in nested unions.

For list[Component | Track] | str, the inner union overwrites the outer True context. The traversal reports referenced=False and rejects a dashed edge. Use in_reference_union or str in args and add a regression test.

The label splitting the component node into four class names is
separated by a middot. Reading the page under a locale which is not
utf-8 decodes that separator to something else, the label stops
splitting, and the test then reports that OpticalPath cannot hold a
class whose name is the whole label -- which is what the five windows
jobs said. test_changelog.py already reads its page this way.
The straddle sentence needed its commas: an acquisition change raises
whatever on_unresolved says, which is what the parenthetical was for.
The bot proposed "applies the configured policy" instead, which is the
opposite of what conform_to_inventory does.

The example pair is built from the model classes in dascore.examples,
not in the block that calls it, so the sentence introducing it now says
which of those two things the reader is looking at.

Thanks — two taken, two declined, in 9391421.

Taken. The straddle sentence did need repair, though not the repair proposed: an acquisition change raises whatever on_unresolved says, so "applies the configured policy" would have documented the opposite of what conform_to_inventory does. It is now "raises, whatever the policy, when a patch straddles a change of acquisition", which is the parenthetical the missing commas were standing in for.

Also taken: the sentence introducing inventory_patch_pair. The pair is built from the model classes, but in dascore.examples rather than in the block the reader is looking at, and the sentence now says so.

Declined — line 204. "One the inventory does not describe" has its subject: "one", standing for the patch in the sentence before it, with the relative pronoun elided. That elision is deliberate and is used throughout the page.

Declined — the .inventory/ directory form. Demonstrating it here would need a second data directory built for the purpose, because a directory holding both spellings at once is refused — a rule the same paragraph states. The two forms are covered in tests/test_core/test_inventory_loader.py; the page states the rule and moves on.

Declined — nested unions in _walk. The shape it protects against, a str unioned with a container of models, appears nowhere in the inventory models, and what it would mean if it did is not obvious: the rule the guard enforces is a str in the same union as the model. The failure mode is also the safe one — the inherited context is lost toward referenced=False, which rejects a dashed edge loudly rather than passing a wrong one silently.
