Brand-aligned theme refresh, semantic zoom on validation plots, new data agent skills, tunable solver options with PyBaMM 26.6 support
Brand-aligned theme refresh
Studio now follows the Ionworks brand guide. Pink (#FF87B7) drives primary
CTAs, selection, focus, and active nav/tabs; green-black (#020E0D)
anchors text and neutrals; blue (#0C68E9) is reserved for
hyperlinks so links stay obviously clickable. Corners are sharpened
to 4px, typography is updated, and JSON viewers, plots, tables, and
ID chips have been re-skinned to match. All changes are
theme-level — no underlying behavior changes — so every screen
lifts at once.Semantic zoom on pipeline validation plots
Validation plots now fetch their data on demand and decimate server-side based on the visible x-range. Box-zoom into a region re-requests denser data for that window; a step-back zoom and a full-reset control are stacked in a zoom history.Tunable solver options with PyBaMM 26.6 support
ionworkspipeline simulations accept new solver options that merge
over the tuned defaults — e.g. enabling compilation for long
unified-experiment runs without restating the rest of the solver
configuration. It threads through every simulation-backed objective.
The workspace also upgrades to PyBaMM 26.6, with a compatibility layer
so historical and freshly-generated payloads both decode correctly.New data agent skills
Two new agent skills land this release:build-data-report
(multi-section markdown + PDF analysis covering rate capability,
DCIR, OCV, GITT, entropic, aging, and gap analysis) and
validate-data (a pre-upload gate covering header audit, schema,
and strict measurement validation).Studio

Improvements
- Cell-measurements list endpoints have been consolidated and now use server-side pagination across project, spec, and instance scopes, keeping the main list view fast even for large datasets.
- Deleting a project no longer shows a misleading “The project you are trying to access does not exist…” toast. The delete confirmation dialog also now requires typing the exact project name to enable the Delete project button, matching the destructive-action pattern used elsewhere.
- Signed-URL generation for measurement files now retries automatically on transient network timeouts, and file listing uses a single batched request instead of many parallel calls. File downloads also retry when the storage service returns an unexpected response under load, and surface exhausted attempts as a clear error instead of a generic failure.
- Cell-instance measurements grid no longer renders the previous spec’s rows after navigating between specs; the cell selector shows a loading skeleton and no longer stalls when an unrelated fetch is in flight; the ECM measurement selector switched to true server-side pagination instead of loading every project measurement into memory.
- The drive-cycles template list endpoint no longer errors at runtime, and now supports standard pagination.
- Fixed an autocomplete component bug where custom dropdown styling options were silently ignored.

Improvements
- A new fit option skips extra pre- and post-fit result-capture simulations that aren’t surfaced to the user, speeding up server-side fits by default; local users keep the previous behavior unless they opt in.
- Configuration errors are now classified more reliably, so the Configuration error UI path lights up correctly instead of being reported as a generic solver error.

Improvements
client.simulation.get_result()returns a typedSimulationResultobject withtime_seriesandstepsas DataFrames (polars by default, pandas whenset_dataframe_backend("pandas")is active) andmetricsas a plain dict, replacing the previous raw-dict response. Callers use attribute access and.columnsmembership checks instead of dict-key lookups.

Improvements
- New
sim-resultsSDK skill: fetching time-series and step data from a completed simulation, computing SOC via step-boundary cumulation, identifying step types by mean current, deriving DCIR from pulse steps using an OCV baseline plus onset current, and polars-aware plotting conventions. - The
parameterizeskill now documents electrode geometry (thickness, porosity, particle radius, AM fraction, maximum concentration) as a hard build requirement for DFN/SPMe — a physics-based model cannot be assembled without these structural parameters. Geometry lives on the cell spec’s components (not on a measurement), can come from teardown / metrology / vendor datasheet / literature, and FPBM is no longer offered as “available” for Tier-2 cells that lack it.
