Compliance wizard — ESPR gate, EV fields, and UX improvements

A broad set of improvements to the DPP creation wizard covering ESPR compliance gating, eight new EV battery fields, a redesigned step order, and a range of UX improvements including date pickers, country dropdowns, and company profile auto-fill.

Added​

ESPR compliance gate​

DPP submission now includes a binary ESPR approval gate as the final step before publishing. The gate evaluates all mandatory ESPR fields and blocks publication if any are missing or incomplete — replacing the previous percentage-based completeness check. ESPR-mandated fields are marked inline with a help link to the relevant regulatory requirement.

New EV battery fields​

Eight additional fields added to the EV battery DPP template: rated voltage (minimum, maximum, nominal), manufacturer phone number, product model identifier, and three compliance declaration fields. These fields align with the full field set required under EU Regulation 2023/1542 for electric vehicle batteries.

DPP wizard redesign — 11 compliance-ordered steps​

The DPP creation wizard has been reorganised into eleven steps ordered to match the regulatory compliance workflow — identity and classification first, technical performance mid, supply chain and compliance last. A template preview is now shown on the opening step so operators can see the full field scope before beginning.

Date picker with year and month navigation​

Date fields across all DPP templates now use a calendar picker with year and month dropdown navigation, making it practical to select historical dates (certificate issue dates, audit dates, manufacture dates) without clicking through months one at a time.

EU country dropdowns​

Country fields that are restricted to EU member states now use a 27-country dropdown rather than a free-text field. This ensures published DPPs contain correctly formatted, machine-readable country values.

Company profile auto-fill​

The DPP wizard now pre-fills manufacturer and operator contact fields from the company profile, reducing repetitive data entry for operators managing multiple products.

DPP ID collision prevention​

Product identifiers now include a random offset component when auto-generated, preventing collisions between products created close together in time.

Storage access controls​

Draft and submitted DPPs are no longer accessible via direct storage URLs. Only published DPPs are publicly readable; in-progress records require an authenticated session.

Signed URL validation​

The public DPP viewer now validates that file references use correctly signed URLs before rendering, preventing broken asset references in published passports.

Email template redesign​

Transactional emails (invitations, OTP, data request notifications) have been redesigned with a gradient header and improved layout, aligned with the Traceable brand.

Changed​

  • Non-ESPR mandatory fields have been reclassified from hard-required to soft-required, allowing operators to publish a DPP that satisfies ESPR requirements even if non-ESPR fields are incomplete. The completeness score reflects the total fill rate.
  • Auto-save no longer resets the form after each save. Previously, auto-save was calling form reset, which caused data entered between saves to be lost in some edge cases.
  • The wizard Next button advances immediately; saving happens in the background and does not block navigation.
  • Optional array fields (lists of hazardous substances, certifications, etc.) are now collapsed by default, reducing visual clutter for operators who don't need them.
  • File upload fields are treated as soft-required — the ESPR gate evaluates them, but the wizard does not block step-by-step navigation if a file hasn't been uploaded yet.
  • Carbon footprint values are now expressed as kg CO₂e (a number) rather than as a percentage, matching the unit specified in the EU Battery Regulation.

Fixed​

  • Auto-save data loss — form reset after save was causing in-flight field values to be discarded.
  • Circular dependency in form watch causing a stack overflow on certain field configurations.
  • Login redirect stuck state — the post-login redirect now correctly resolves in all session states.
  • Select field TypeError on Radix UI during account signup resolved.
  • CSV template generation error now surfaces clearly rather than failing silently.
