Tracked gaps

Near

  • gap:apg-coverage — Accessible Rich Internet Applications (WAI-ARIA) 1.2 (WAI-ARIA, Subset ) in studio-ui-guidelines.md §6, studio-ui-guidelines.md §8, studio-ui-guidelines.md §12 — The tree, menu, toolbar and radiogroup patterns are implemented with their full state and keyboard contracts, and two more now are: the combobox (Quick Access carries aria-controls , aria-activedescendant and an aria-expanded that is false when nothing matched — it was the literal string true ) and the dialog ( role , aria-modal and a name off the wrapper's headline). The tab strips still carry no tab semantics, and the Tabulator data grid is virtualized — hand-authoring role="grid" over rows that do not exist in the DOM would make it worse, not better.

Untiered

These bind a section carrying no status marker, so no tier can be derived.

  • gap:wcag-conformance — Web Content Accessibility Guidelines (WCAG) 2.2 (WCAG 2.2, Subset ) in studio-ui-guidelines.md §1.1, studio-ui-guidelines.md §8.2, studio-ui-guidelines.md §8.7 — No level is claimed, and conformance is not tested end to end — that needs a browser. Four criteria are met deliberately and checked: SC 4.1.3 (Status Messages) — one live region, called from notify() itself, so a failure that lands in the Problems panel is still announced; SC 2.5.7 (Dragging Movements) — cut/paste is the stated alternative to every drag; SC 1.4.3/1.4.11 (Contrast) — a required-pairs table gated in check-styles.ts , with one entry on the debt list; SC 1.4.1 — a forced-colors block redraws the selection and focus affordances Windows High Contrast deletes with box-shadow .

Declined

Standard Where Because
Source Map Format Specification ECMA-426 server.md §5 the only mapping the code services perform is subtracting one synthetic header line and a fixed byte offset from each diagnostic, which is exact, total, and four lines of arithmetic. A source map would encode that constant as a generated artefact the snippet does not otherwise need, and every consumer would have to learn to read it. The snippets are function bodies edited in place, never shipped, so nothing downstream has a debugger to point at them.
JavaScript Object Notation (JSON) Patch RFC 6902 extensions.md §8.3 lower rewrites a section value into the document tree as a whole-value transform, and a patch document would describe the same result less legibly while adding a format an extension author would have to learn. The capability signature is the contract instead.
JavaScript Object Notation (JSON) Text Sequences RFC 7464 server.md §4.1 the only advantage over the application/x-ndjson already in use is that a record containing a raw newline cannot break framing, and the producer is always JSON.stringify , which escapes newlines — so the framing is unambiguous already. Adopting it would break every client and test and make a dev-server debug stream ungreppable. The defect that looked like a framing problem was not one: the reader dropped unparseable lines in silence, so an import finished looking clean while the user never learned what it skipped. They are counted and reported now ( packages/studio/src/services/import-client.ts ).
JSON Web Token (JWT) RFC 7519 desktop.md §3.6 Jx issues and validates no JWTs. The desktop holds an opaque provider access token, and the loopback server's own gate is a random per-server token compared in constant time. The strongest posture against the JWT BCP's failure modes — alg: none , unverified kid , confused audiences — is not having a JWT, and adopting one to be conformant would create every risk it then manages.
Compression Extensions for WebSocket RFC 7692 collab.md §2 lib0-encoded Yjs updates are near-incompressible, the dominant frame volume is awareness cursors whose payload is smaller than a deflate block header, both transports are loopback or already compressed at the edge, and Bun allocates a zlib context per socket — a real cost for a server whose purpose is many concurrent sockets.
OAuth 2.0 Authorization Server Metadata RFC 8414 desktop.md §3.6 the flow this would configure now exists, and the provider it talks to publishes no metadata document at either well-known URI. Discovery would be a request that always 404s, followed by the hard-coded endpoints below it. A second provider that does publish one is what would make this worth having.

Adoption backlog

Standards whose owning spec section does not exist yet, so no row can bind them. Each names the spec that will own it; when that section is written the entry becomes a tracked gap.

Standard Target Why not yet
CSS Cascading and Inheritance Level 5 CSS Cascade Layers spec.md §9 The style model has no layer concept; adding one is a design change, not a citation.
CSS Containment Module Level 3 CSS Containment 3 spec.md §9 $media is viewport-only. Container queries would need a named-container model in the style object.
CSS Shadow Parts spec.md §16.6 — ::part from outside Shadow roots exist now (the $shadow opt-in), so ::part is finally possible — but nothing emits a part attribute and no selector addresses one from a page stylesheet, so there is no behaviour to cite yet.
Media Queries Level 5 Media Queries 5 spec.md §9.4 $media borrows @custom-media 's shape from this level, but Jx resolves it itself and no browser ships it — so there is nothing to conform to until one does.
Web Authentication Level 3 WebAuthn Level 3 desktop.md §10 Passkeys need a registered relying-party id and a recovery story, neither of which is designed.
