…blems count

- Add a proper GTS sidebar view (gts.fileExplorer) that lists every
  discovered GTS file in a folder tree, colors files green/red via a
  shared FileDecorationProvider driven by the same registry/diagnostics
  used elsewhere in the extension, shows a problem-count badge, and
  opens files in the editor on click. Replaces the previously dead
  webview-type sidebar view that never had a provider registered.
- Extend GTS ID decorations, hovers and document links (previously
  JSON/JSONC only) to YAML files, using the yaml package's CST to get
  offset-accurate ranges for scalar nodes. Broaden the Ajv error
  position-matching regexes to also handle unquoted/single-quoted YAML
  keys and values, not just double-quoted JSON.
- Remove a duplicate GTS entity not found diagnostic in the link
  provider that double-reported broken GTS references already surfaced
  by the shared validator.

Changing a GTS file now revalidates the files whose entities depend on it,
not just the file itself. Previously the VS Code extension only revalidated
the changed document, and the Web/Electron apps did a full re-scan on every
change, so broken derived types/instances went unnoticed and workspace
findings were incomplete after a reload.

Centralize the logic in the shared JsonRegistry so behavior is identical in
VS Code, the Web app and Electron:

- Add a cached, cycle-safe reverse-dependency graph with two edge kinds:
  structural (derivation, multi-level derivation, instantiation, $ref/allOf)
  followed transitively, and id references (any GTS id, x-gts-ref) applied
  depth-1.
- Add getDependentFilePaths / validateFile / revalidateAfterChange and a
  single applyFileChange entry point (handles reindex, deletion and
  rename/removal via previous-id capture).
- VS Code: revalidate dependents (open docs precise, closed docs coarse) and
  validate the whole workspace on initial/viewer/disk-settle scans so the
  problem count is complete after a window reload.
- Web/Electron: route watcher events through applyFileChange for incremental,
  serialized revalidation instead of a full re-ingest.

Two issues in the GTS sidebar ("Discovered GTS Files"):

1. Every change refreshed the whole explorer, which fired both a full
   tree rebuild and a global file-decoration invalidation. That made all
   rows flash white->green twice on each edit. The tree now only rebuilds
   when the set of discovered files actually changes, and decorations are
   refreshed per-URI (error-state changes are already handled by the
   onDidChangeDiagnostics listener), so unrelated files no longer blink.

2. Workspace symlinks (.gts-spec, .gts-spec-ext, .gears-rust/.gts-spec)
   made the same physical file reachable via several paths, so the same
   GTS entity was scanned multiple times -> duplicate tree rows and a
   nondeterministic id->file mapping. Scans now index each physical file
   once (resolved via real path), preferring open files as canonical, and
   the incremental change/delete/rename handlers keep a single entry per
   physical file.

…iles

YAML config files can define GTS types/instances inline under nested
`entities:` arrays (e.g. a service's `types-registry.config.entities`
seed block). Previously the whole document was flattened by the generic
id walker, so those `$id` definitions were harvested as references and
reported as "GTS reference not found".

Recognize and register such inline definitions (YAML only; JSON/JSONC/.gts
keep the strict single-entity / top-level-array shape) and document the
behavior in the shared and VS Code extension READMEs.

Support arbitrary-length GTS chains by resolving cumulative segment IDs
and marking all descendants after a missing ancestor as invalid.

Keep decorations, links, and hover information consistent with broken
GTS inheritance chains.

Signed-off-by: Artifizer <artifizer@gmail.com>
The "GTS reference not found" diagnostics carry a precise instancePath
that includes array indices, but findErrorPosition fell through to a
regex that matched the first textual occurrence of the leaf key. All
errors on a repeated key (e.g. subject_type across several tokens)
collapsed onto the first instance.

Add a path-aware resolver that navigates the YAML/JSON AST to the exact
node at the instancePath (honoring array indices) and use it for
value-leaf errors (gtsId reference, x-gts-ref, gts-uri-prefix), so each
error lands on its own instance value. Falls back to the previous
text-search strategies when the path cannot be resolved.

ajv-formats' default "full" mode splits date-time on /t|\s/i, so it
accepts a space instead of the RFC 3339 "T" separator (e.g.
"2008-10-12 10:30:00Z"). Compose the standard ajv-formats "fast" and
"full" validators for date, time and date-time so a value must satisfy
both the strict grammar (T separator + mandatory offset) and the real
value-range checks (month/day, leap second, offset <= 23:59). No
hand-rolled RFC logic.

GTS ID segments were colored schema/instance from the resolved entity's
isSchema flag, which reflects the referenced document shape rather than the
structural type-ness of the ID itself. A malformed instance whose id ends in
"~" was thus painted green (instance) even though the trailing "~" makes it a
type.

Derive schema-vs-instance in the shared analyzeGtsIdForStyling from the core
library (isGtsType/Gts.isType), using the registry lookup only for existence.
Refactor the VS Code linkProvider to consume the shared analyzer instead of
its own duplicated registry-isSchema loop, so all clients share the core logic.

When a GTS file was opened as a preview tab, validateOpenDocument replaced
its coarse workspace diagnostic with precise in-editor diagnostics. Closing
that preview (by clicking another file in the Explorer) only deleted the
precise diagnostic and never restored the workspace marker, so the file lost
all GTS diagnostics and the Explorer decoration painted it green despite
still being invalid.

Republish the coarse workspace diagnostic on close via validateClosedFile,
reindexing from disk first so a discarded unsaved buffer does not leave stale
content in the registry.

Also give the two GTS diagnostic collections distinct names
(gts-validation / gts-link-format) so ownership is unambiguous.

Prevent deleted files from remaining in the Discovered GTS files tree and
ensure validation decorations consistently reflect the latest workspace
state.

Serialize full workspace scans and retry scans invalidated by concurrent
filesystem or editor mutations. Track registry revisions and replace the
registry only when its source snapshot is still current, preventing older
scans from overwriting newer incremental updates.

Version per-file mutations so asynchronous reads from create/change events
cannot re-index a file after a newer delete or rename event. Always invalidate
deleted paths, and verify that files still exist before adding their contents
to the registry.

Filter missing filesystem paths from the explorer as a final consistency
check. Initialize the tree after its providers are registered and reconcile it
when diagnostics change so newly discovered files receive decorations
immediately.

Add generations to document and workspace validation runs. Discard validation
results when a newer run or registry revision supersedes them, preventing
partial or stale valid/invalid statuses from being published.

Start the initial workspace scan only after diagnostics, filesystem watchers,
and the GTS explorer have been registered.

Signed-off-by: Artifizer <artifizer@gmail.com>
Propagate a direct parent's GTS validation failure to an otherwise-valid derived schema so inherited errors produce an authoritative diagnostic on the derived file instead of only red identifier segments.

Make Explorer file status consult registry validation results in addition to VS Code diagnostics. This preserves the invariant that any failed GTS validation marks the complete file as problematic, even while diagnostic publication is pending.

Signed-off-by: Artifizer <artifizer@gmail.com>
Remove the registration-success workaround that accepted an entity identified by `$id` even when gts-ts classified it as an instance with no schema.

Always preserve the validateInstance verdict for schema-less entities so double-dollar schema-marker artifacts produce a diagnostic, an editor underline, and a problematic file decoration.

Merge Risk: 🔵 Low · up to 1f88c

Some validation edge cases can miss dangling references, report false duplicate IDs, or show a diagnostic in the wrong place. Invalid instance references can still look valid in the web views, and the extension changelog lists release notes under the wrong version. These are bounded issues that can be fixed in follow-up work.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 1f88c

The design changes affect workspace-wide validation and editor-to-viewer synchronization. Reviewed hover paths restrict command authority, and layout roots are selected from workspace folders. No introduced exploit was established, but incomplete baseline and exceptional-failure coverage leave limited uncertainty.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — Workspace authors can influence registered schemas, instances, dependent validation, and editor navigation across the shared workspace registry. The inspected sensitive outcomes are editor operations and layout persistence; this trace does not establish production-service, credential, or IAM exposure.

Trust Boundaries and Controls

  • observed — Generated replacement links serialize the current document URI and hover range, use registry-resolved suggestions, and escape labels. Definition targets use registered file paths converted to file URIs. These controls provide counterevidence to direct workspace-text command injection; they do not establish general argument validation at the registered command handler.
  • observed — Layout routing selects the registered entity's containing workspace folder or falls back to the first folder. The new wrapper caches stores by root and delegates to existing storage, which sanitizes filenames and keeps only the current snapshot. This bounds logical root selection, but does not prove symlink confinement or atomic recovery from interrupted writes.

Resilience and Maintainability Implications

  • inferred — The inspected normal relay path provides stronger ordering guarantees than the absence of a correlation token alone suggests: host posts are serialized, file registration is synchronous, and the webview returns before schema-compilation awaits. A newly introduced cross-scan validation mix-up was therefore not established.

Hardening Proposals

  • proposed — Consider carrying a shared snapshot identifier in scan and validation messages and rejecting mismatches. This would make freshness explicit if future ingestion introduces asynchronous work; it is not evidence of a current exploit.

Two related correctness fixes to how the extension surfaces GTS entities
that exist but fail validation.

1. Hover no longer says "GTS Entity Not Found" for an entity that is
   present but invalid. The hover previously forced the lookup result to
   undefined for any segment the styling analyzer flagged as an error
   (which includes existing-but-invalid entities), so it fell into the
   not-found branch and contradicted Cmd+Click, which resolves the same
   entity via a plain existence lookup. The hover now looks the entity up
   by presence (matching the document-link provider) and, when it exists
   but is invalid, shows a "GTS Entity Invalid" note with the underlying
   validation error while keeping the navigable definition link.

2. "Referenced x-gts-ref entity '<id>' is invalid" diagnostics now anchor
   to the offending x-gts-ref node instead of the schema's $id. The gts-ts
   error mapper only resolved a precise location for messages beginning
   with "Property '...'", falling back to /$id for everything else, so the
   squiggle landed on the $id line rather than the x-gts-ref that caused
   it. A new findXGtsRefPath() locates the x-gts-ref whose value matches
   the referenced id and the mapper uses that path (still falling back to
   /$id when it cannot be located).

…hema

OP#13 trait-completeness failures from gts-ts arrive as "trait validation:
..." messages with no field path, so the extension's error mapper fell back
to anchoring them on the schema's $id — the squiggle landed on line 2
instead of the unmet trait requirement.

Add findTraitRequiredPath(), which resolves the offending requirement to the
specific `required` entry in the document's top-level x-gts-traits-schema
(e.g. /x-gts-traits-schema/required/0) when the missing trait can be named,
or to /x-gts-traits-schema otherwise, and null when the requirement comes
from an ancestor (so the mapper keeps the /$id fallback).

Wire it into the gts-ts error mapping: messages beginning with "trait
validation:" now extract the missing trait name and anchor there, alongside
the existing Property '...' and Referenced x-gts-ref entity '...' handling.

…erences

GTS references were harvested purely syntactically: every GTS-id-shaped
string in an instance was treated as a reference and checked for existence,
regardless of the field's schema. A value that merely looks like a GTS id in
a plain data field (e.g. a `format: uuid` string whose value is
"gts.x…v1~<uuid>") was therefore reported as "GTS reference not found" on top
of its real format error.

Make the existence check schema-aware for instances:

  - add getInstanceFieldSubschema(), which resolves the subschema governing a
    value at an instance source path (through properties, array items, and
    allOf/anyOf/oneOf branches);
  - add isScalarDataField(), true when a subschema constrains the value with a
    scalar type/format/enum/const and is NOT a reference (x-gts-ref/$ref);
  - resolve the instance's schema and skip the existence check for such scalar
    data fields.

Configured GTS id/schema fields (id, gtsIid, type, $schema, ...) are never
exempted, and genuine reference fields (x-gts-ref/$ref) still report missing
targets. When the schema cannot be resolved locally the previous behaviour is
preserved.

…dation

Reworks the scan/registry/validation lifecycle so a re-scan can no longer
leave stale state behind, and so workspace validation stays responsive.

- Re-scan is now a full rebuild. A user-triggered rescan first tears the
  store down to empty (resetGtsStore: registry, symlink-dedup index,
  .gitignore cache, cached scan files, and all validation/link diagnostics)
  and then repopulates from a fresh enumeration, so entities for files or
  directories removed since the last scan can't survive as stale "ghost"
  tree entries. refreshGtsFileExplorer reuses the same reset.

- registryStore: drop rebuildRegistryIfUnchanged; scans rebuild the registry
  unconditionally, so a fresh full file set always replaces the previous one
  instead of being discarded on a revision race.

- validation: make validateWorkspaceInBackground single-flight and
  time-sliced. Overlapping requests coalesce into one follow-up pass (no
  starvation), the pass yields to the event loop every ~25ms (no multi-second
  freeze of hovers/tree/typing on large workspaces), and it keeps sweeping
  until every current entity is validated instead of aborting when the
  registry changes mid-pass. Removes the unused scope-roots filtering.

- helpers: isGtsCandidateFile ignores non-file URI schemes (git:/ quick-diff
  originals, compare views, untitled buffers) so virtual documents sharing a
  real file's fsPath can't overwrite the working copy's entities or churn the
  registry.

Signed-off-by: Artifizer <artifizer@gmail.com>
Fixes files showing green in the GTS tree until opened, stale entries after
folder deletes/renames, and a command-injection hole in hovers.

- validation: the workspace pass iterated the id-keyed jsonSchemas/jsonObjs
  maps, which hold one entity per id (last indexed file wins). Any entity
  whose id is also defined in another file was never validated, so its file
  stayed green until opened. With gts-spec/gts-test-examples and a second
  copy of gts-test-examples in the workspace, 1172 of 2259 entities were
  skipped this way. The pass now walks jsonFileSchemas/jsonFileObjs, i.e.
  every entity of every indexed file.

- linkProvider (security): hovers set isTrusted = true, enabling every
  command: link, while escapeMarkdown left backslashes unescaped, so file
  content such as `\[x\](command:...)` rendered as a live link that runs an
  arbitrary VS Code command on click. Hovers now enable only
  gts.replaceGtsId, and escapeMarkdown escapes all CommonMark-escapable
  punctuation including the backslash.

- extension: folder deletes and renames are reported by VS Code as a single
  event for the folder, which the file-extension checks and the GTS glob
  watcher never matched, leaving every nested file indexed. In-IDE and
  on-disk folder deletes/renames now drop everything indexed under the
  folder, and folders that appear (created, moved in, renamed) are indexed.
  Folder-create bursts are batched so each new top-level folder is scanned
  once.

- extension: the viewer ran its own fast-pass-only scan and then replaced
  the shared registry with it, so files only found by phase 2 (build/,
  vendor/, out/... when not gitignored) disappeared from the tree and from
  validation on every edit while the viewer was open. The viewer is now fed
  from the shared registry; its rescan button runs the regular full scan.

- extension: editor changes used one shared debounce timer, so editing a
  second file within 500ms cancelled the first file's validation and
  dependents revalidation. Timers are now per file, with a separate
  debounce for viewer refreshes.

- linkProvider: "Invalid GTS ID format" diagnostics used source 'gts' while
  the tree, badge and file decorations count only 'GTS', so such files
  showed green. They now use 'GTS' and are cleared when the document closes
  instead of going stale.

… exclusions, multi-root

Makes file statuses independent of which files happen to be open, and
makes scanning consistent across code paths and workspace folders.

- Duplicate ids: every entity whose id is also defined in another file (or
  again in the same file) now gets a 'gts-duplicate-id' warning naming the
  other definitions. The registry resolves an id to one definition only
  (last indexed wins), so references to a duplicated id silently depended
  on scan order. Warnings show precisely on the id field for open files and
  coarsely for closed ones; editing or removing one copy revalidates the
  others. The tree colours warning-only files yellow (errors stay red) and
  the badge counts errors and warnings.

- Malformed ids in closed files: the "Invalid GTS ID format" check ran only
  in the link provider, i.e. only for open editors, so a closed file went
  green. Detection now runs on indexed content (new gtsIdFormat.ts, same
  rules as the link provider) and is reported by the validator for open and
  closed files alike; the link provider keeps the red chip but no longer
  publishes a second marker. Files whose only GTS content is malformed are
  now listed in the tree.

- validation: open-file, closed-file and workspace diagnostics are built by
  one collectFileProblems() (parse errors, entity errors, malformed ids,
  duplicate warnings), so the three paths always agree.

- One exclusion rule: scans, file watchers, folder handling and re-syncs
  all skip exactly .git/ and .gts-viewer/ plus whatever .gitignore
  excludes. The watcher used to hard-code node_modules/ and dist/, so a
  non-gitignored dist/ was indexed by the scan but its changes were never
  tracked. Build/dependency directories are still only deferred to phase 2.

- No silent truncation: phase 2 and the .gitignore enumeration are no
  longer capped. Phase 1 keeps its latency cap (per folder), logs when it
  is hit, and phase 2 indexes everything beyond it.

- shared: validateEntity builds its result locally and assigns it once.
  It awaits (Ajv compileAsync, parent validation), so overlapping
  validations of the same entity reset and appended to the shared
  entity.validation in interleaved order, duplicating or dropping errors.

- Multi-root workspaces: .gitignore rules are loaded and applied per
  workspace folder (one folder's rules no longer hide paths in another),
  files are enumerated per folder with that folder's excludes, the tree
  gets one top-level node per folder, displayed paths are folder-qualified,
  and viewer layouts are stored in the .gts-viewer/ of the workspace folder
  that holds the diagram's entity.

…viewer paths

Cuts the extension's steady-state and scan cost without changing any
validation result (verified: all 2224 entity results in the gts workspace
are identical before and after).

- shared: validateEntity results are memoized per entity for the current
  registry content generation (bumped on every index/invalidate/reset), so
  a pass validates each entity once instead of re-validating the whole
  parent chain for every derived schema, and concurrent callers share one
  computation. Instance validators are compiled once per schema per
  generation instead of once per instance (each still gets its own Ajv, as
  before). The gts-instance-id/gts-type-id annotation formats (paired with
  x-gts-ref, which enforces them) and schemars' sized-integer formats are
  registered as accept-all, which is how Ajv already treated them, without
  the "unknown format" warning on every compile. Full workspace pass
  9.0s -> 6.1s; an unchanged repeat pass 9.4s -> <1ms; warnings 232 -> 12
  (the rest come from gts-ts's internal Ajv).

- Activation: replace onStartupFinished with workspaceContains for
  gts.*.{json,jsonc,yaml,yml} and *.gts files plus onLanguage:gts (views
  and commands activate implicitly), so unrelated workspaces are no longer
  scanned. Drop the "GTS Viewer is ready!" popup shown on every start.

- linkProvider: parsed references are cached per document version and
  carry their content offset, so decorations, hovers and links no longer
  copy the whole document text per reference or re-parse it per hover.
  Definition links are resolved lazily (resolveDocumentLink) and locate
  the entity's id field (or its list item) via the JSON/YAML tree, read
  asynchronously and cached per registry revision; previously every link
  request did a synchronous disk read per segment of every reference and
  matched the first line merely containing the id.

- validation: error positions share one lazily parsed document per
  validation instead of re-reading and re-parsing the text per error.

- Viewer: validation results come from the shared registry, which the
  scan's workspace pass and per-edit revalidation keep current; the
  viewer is refreshed after the edited file and its dependents are
  re-checked. It used to build a second registry and re-run Ajv over the
  whole workspace on every debounced edit.

- Explorer: diagnostics changes of other extensions (e.g. TypeScript on
  every keystroke) no longer refresh the tree or recount every diagnostic
  in VS Code; only GTS files are repainted, tree/badge work is debounced,
  and the badge counts this extension's own collections.

- Scans read files 32 at a time (order preserved, so duplicate-id
  resolution is unchanged) and always use real file documents, never a
  git:/ quick-diff copy with the same fsPath. Folder indexing likewise.

- Logging: drop per-error, per-object and per-validation logs from the
  editor paths; only lifecycle and per-scan/per-pass summaries remain.

Instances of any type derived via `allOf: [{ "$ref": "gts://<parent>" }]`
were reported with "Cannot resolve $ref 'gts://<parent>' for x-gts-ref
traversal", even though the parent schema exists and Cmd+click resolves it.

The XGtsRefValidator was constructed without a store, so it could never
follow a gts:// $ref into the parent schema. That used to be skipped
silently; gts-ts now fails closed on an unresolvable $ref (0390a1b,
"fix(x-gts-ref): preserve selected leaf through composition"), turning
every such instance red.

Pass the registry's gts-ts store so the parent's x-gts-ref constraints
are actually traversed and enforced. Existence checks stay off
(GtsRefValidationMode.None): referenced-entity existence is already
reported by the registry's own gtsRefs check, so enabling them would
duplicate "not found" errors. The entity's own id is passed as selfId.

In the gts workspace this removes the false error from 160 entities (145
were red only because of it) and surfaces the real x-gts-ref violations
it was masking in the 8 invalid/testref_selfref test instances; no other
validation result changes.

gts-ts now compiles schema patterns with re2-wasm (c9070a8, "compile
schema patterns with RE2 to prevent ReDoS"). re2-wasm loads its re2.wasm
binary from the directory of the running script, which for the esbuild
bundle is dist/, so every build since then threw ENOENT on load and the
extension never activated.

Copy re2.wasm (resolved through gts-ts, i.e. the exact copy it depends on)
into dist/ at the end of every successful build, including watch rebuilds.
The .vsix staging already copies all of dist/, so packaged builds get it
too.

An instance was validated only against its own content, so an instance
whose type (or an ancestor of it) is invalid still showed as valid. This
is how gts-ts's store.validateInstance and the gts-test-examples
expectations treat it: e.g. invalid/instances/123e4567-...-426614174000
and gts.x.test13.aggaddbad...example.v1, whose ancestor type is missing a
required trait, were green.

After resolving the instance's type, validate it (a memoized lookup
within the registry generation) and, if it has errors, add
"Instance type '<id>' is invalid: <first type error>" on the instance's
type/id field. The type's result already carries its ancestor chain, so
a broken ancestor propagates to instances too.

Against the previous commit, built with the same gts-ts, exactly 49
entities change in the gts workspace and each one only gains this error.

The gts:// prefix check (0e819cb) reported a GTS id with the "gts://"
prefix in any field other than $id, $ref and x-gts-traits-schema as a
malformed identifier. Neither the GTS spec nor gts-ts forbids that: the
spec only requires the prefix where JSON Schema consumes the value as a
URL ($id/$ref), and implementations strip it everywhere else. The spec's
own fixture relies on it - valid/types/gts.x.test6.dref_dd.standalone.v1~
puts "gts://..." under the non-keyword "$$ref" and expects the type (and
its instance) to be valid, but gts-kit showed both red.

Align with the spec and gts-ts: keep flagging a missing gts:// in the URL
fields and a gts:// prefix followed by an invalid GTS identifier, and drop
the 'unexpected-uri-prefix' case.

In the gts workspace, built against the same gts-ts, exactly 8 entities
change and each one only loses these errors: the dref_dd type and
instance (both copies of gts-test-examples) and four schemas under
gts-kit/examples/events/schemas that use gts:// in id/$schema/type/
subjectType values.

…t item

Two problems visible in the GTS file tree and in list (array) files:

- Two colors for GTS problems. Duplicate ids were published as warnings,
  so with VS Code's standard Problems decorations (1ef0482) files with
  only a duplicate id showed in the warning color while other GTS files
  showed in the error color. Duplicate ids are now errors like every
  other GTS problem, so all problem files share the standard error color
  and count. The now-unused warning plumbing is removed (per-problem
  severity, warning-only tree tooltip), and the view badge counts all
  GTS problems.

- Errors on the wrong item of a list file. Entity validation reports
  instance paths relative to the entity, which equals the document only
  for single-entity files. In a top-level array every item's error
  (e.g. an invalid `clientId` in each of three instances) resolved to
  the first item's field, stacking all markers there. Errors of list
  entities are now prefixed with the entity's index (entity-level errors
  point at that item's id field) before positions are resolved - for
  diagnostics and for the link provider's red field chips. The
  `required` and `schema` position lookups also resolve the object
  structurally first instead of text-searching for the first
  `"<key>": {`, which had put e.g. a missing-property error of the 4th
  item on the 1st item's object.

A schema whose regex gts-ts cannot compile (e.g. "failed to compile trait
schema: Unsupported pattern /^(a+)+(?=b)/: ...") was reported on the
schema's `$id`: the shared registry anchors gts-ts schema messages by
recognising a few shapes (property, x-gts-ref, missing trait) and falls
back to `/$id` for everything else.

- shared: add findRegexPatternPath, which locates the `pattern` value or
  `patternProperties` key whose source the message names as `/<source>/`,
  and use it for regex compile errors ("Unsupported pattern",
  "Invalid regular expression"). Path segments are escaped per RFC 6901,
  since `patternProperties` keys often contain `/`. Errors about a regex
  of an ancestor schema keep the `$id` anchor.
- vscode: unescape RFC 6901 `~1` / `~0` in instance-path segments, so
  such paths (and Ajv's own escaped instancePaths) resolve to the right
  key or value.

🟡 Minor · Require an ID field for inline YAML entities definitions. · registry.ts:607-611

packages/shared/src/registry.ts:607-611
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Require an ID field for inline YAML entities definitions.

registerEntity(def, undefined) accepts any element of a nested entities array when isGtsEntity() is true. isGtsEntity() is also true for an element that has no ID but contains a GTS reference, because gtsRefs is not empty.

For such an element, the JsonObj constructor falls back to this.id = this.file?.path. Two ID-less elements in one file then share the file path as their ID:

  • The second element overwrites the first element in jsonObjs.
  • buildDefinitionIndex in apps/vscode-extension/src/validation.ts records the path twice.
  • duplicateIdProblems then reports a false Duplicate GTS id "<file path>" diagnostic.

Line 598 already applies the selected-ID check to top-level YAML entries. Apply the same check to inline definitions.

🐛 Proposed fix
     if (isYamlFileName(name)) {
       for (const def of JsonRegistry.collectInlineEntityDefinitions(parsedContent)) {
-        registerEntity(def, undefined)
+        registerEntity(def, undefined, true)
       }
     }

Do not exempt the GTS ID formats in isScalarDataField.

isScalarDataField returns true for any subschema that has a format. Schema generators such as gts-rust emit format: "gts-type-id" and format: "gts-instance-id". createAjvInstance registers both formats at lines 1153-1161, and each one marks its value as a GTS reference.

Consider a field declared as { "type": "string", "format": "gts-type-id" } with no x-gts-ref. For that field, computeEntityValidation skips the existence check at lines 746-752. As a result, a dangling reference in that field produces no "GTS reference not found" error.

Treat these two formats as reference declarations.

Escape object keys in the JSON Pointer that findXGtsRefPath builds.

findXGtsRefPath joins raw keys into childPath. findRegexPatternPath escapes keys per RFC 6901, but this function does not.

x-gts-ref often appears under a patternProperties entry, and those keys often contain /. For such a key, the function returns a pointer with extra segments. instancePathSegments in apps/vscode-extension/src/validation.ts unescapes ~1, so it splits the unescaped key incorrectly. The "Referenced x-gts-ref entity" diagnostic then falls back to a text search or to the document start.

The unchanged findSchemaPropertyPath has the same issue, which a previous review already reported.

🐛 Proposed fix
 export function findXGtsRefPath(content: any, refValue: string): string | null {
   const target = normalizeGtsId(refValue)
+  const escape = (key: string) => key.replace(/~/g, '~0').replace(/\//g, '~1')
 ...
     for (const [key, value] of Object.entries(node)) {
-      const childPath = `${currentPath}/${key}`
+      const childPath = `${currentPath}/${escape(key)}`

Implement the spec's default gts-ref-validation=any-valid policy (§9.6):
an entity referenced through an x-gts-ref field must itself be valid,
transitively, otherwise the referencing instance is reported invalid.

Run the XGtsRefValidator in any-present mode to collect referenced ids
(dropping its "not found" errors, already covered by the gtsRefs registry
check), then validate each referenced entity. Referenced schemas are
validated normally; referenced instances are resolved within the current
validation chain to break reference cycles (treated as valid, matching
gts-ts's visiting guard and avoid deadlocks. Results for cut cycles are
recomputed within the chain and not cached.

Memoize settled validation results so referenced-entity checks can reuse
a finished result for the current generation instead of re-awaiting an
in-progress computation.
