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). **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. **Fixes** * 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 typed `SimulationResult` object with `time_series` and `steps` as DataFrames (polars by default, pandas when `set_dataframe_backend("pandas")` is active) and `metrics` as a plain dict, replacing the previous raw-dict response. Callers use attribute access and `.columns` membership checks instead of dict-key lookups. **Improvements** * New `sim-results` SDK 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 `parameterize` skill 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.
