Backlog sweep and navigation rebinding
Cleared the entire S/XS backlog in one branch, then built the navigation distinct rendering feature on the same branch. Twenty-eight commits total.
The backlog sweep
Nine items knocked out in sequence. The typecheck fixes were mechanical — 19 Element → HTMLElement narrowing issues across pages-runtime test files. The test failures were more interesting: CasehubTable’s filter event was sending the full TypedRow object but the test expected rowIndex. Turned out both are needed — rowIndex is the display-order position (wrong after text filtering), row is the authoritative record reference. A pre-existing bug where clicking a text-filtered table row selected the wrong record fell out of this fix.
The form infrastructure grew: DataSetOptions in dropdowns (via a proxy VizTarget pattern that dispatches a second data request through the existing single-dataset pipeline), cascading dropdown options (re-request on parent field change with filter operations), save error banners, beforeunload dirty-check, SaveAdapter.delete and .create for both local and REST adapters, and record prev/next navigation.
Navigation rendering
The design went through five rounds of spec review before implementation. The key architectural decisions: tree and sidebar are self-contained (own their layout via grid: auto 1fr, no targetDivId), tiles is cards-above-content (like tabs), and wireTabs stays shared for tabs/pills/menu since they differ only in CSS.
Tree required the deepest work. resolveNavGroup in nav-desugar now synthesises hierarchical /-delimited slot names from nested navTree groups when the component type is tree — the slot key "Settings/Profile" is used for panel lookup while the page lookup stays flat ("Profile"). wireTree parses these keys at render time to build nested <ul>/<li> with expand/collapse. Top-level groups start expanded, nested groups collapsed, and programmatic activation via activateSlot auto-expands collapsed parents.
The Navigation Rebinding example now demonstrates three levels of rebinding: top-level pills swap between six nav variants (tree, tabs, menu, sidebar, tiles, carousel), each rendering the same content hierarchy. Inside Sales → Transactions, a secondary pills toggle swaps between table and form views of the same dataset — table shows the full grid, form shows editable fields with prev/next record stepping.
Prometheus parser fix
A quiet bug in the metrics text parser: indexOf("}") found a } inside a URI label value (/api/users/{id}) instead of the label block’s closing brace. The symptom was a SCHEMA_MISMATCH error blaming the Value column — you’d look at the data, see a valid Prometheus line, and be confused. Fix was lastIndexOf("}"). The JVM Monitoring dashboard now renders correctly with its mock data.
