Problem

Pipeline review shows validation failures below the cost estimate, far from the settings that need changes. Publication-loading failures also appear in several places with conflicting retry instructions.

Solution

Attach full-width errors and warnings to their Connection or Data sections. Keep the current scroll position and show description-only guidance above the footer. Consolidate publication-loading failures into one Data-step error with Continue to retry, preserving the existing sheet behaviour.

The main fix, spreading out the error and warnings to their respective sections:

Before After
New Pipeline  Supabase 15619
All at bottom Attached to each section

Misc fixes for API blocks:

Before After
CleanShot 2026-10-21 at 15 19 24@2x CleanShot 2026-10-21 at 15 22 56@2x

To test

  1. Enable Pipeline creation wizard in Feature Previews and open /project/<ref>/database/pipelines/new. Complete Connection and Data to reach Review.
  2. In Chrome DevTools → Network, right-click a captured POST ending /replication/<ref>/destinations/validate (Connection) or /replication/<ref>/pipelines/validate (Data), then select Override content. Reach Review before enabling the destination override. Keep HTTP status 200 and save:
{"validation_failures":[{"name":"Test validation issue","reason":"Test failure for the review screen.","failure_type":"critical"}]}
  1. Click Start pipeline. Expect a flush Admonition at the bottom of the matching section and danger guidance above the footer, without automatic scrolling. Change critical to warning to check warning guidance and Start pipeline anyway. Edit and retry to confirm values persist.
  2. On Data, block the GET ending /replication/v2/<ref>/sources/<id>/publications/<name>. Expect one flush publication-loading failure above the footer, including with Advanced settings open. Continue retries; remove the block and retry to recover.
  3. Check desktop and phone widths. Stop before confirming creation, then remove overrides and request blocks.

📝 Walkthrough

The pipeline review flow now displays validation failures beside the relevant review sections and scrolls to the first applicable issue. A new hook calculates review cost estimates, and the initial estimate loading state affects whether the pipeline can start.

Changes: Pipeline review flow

Layer / File(s) Summary
Review cost calculation and display
apps/studio/components/interfaces/Database/Replication/CreatePipeline/usePipelineReviewCosts.ts, apps/studio/components/interfaces/Database/Replication/CreatePipeline/PipelineReviewCosts.tsx, apps/studio/components/interfaces/Database/Replication/CreatePipeline/PipelineCreationFlow.tsx, apps/studio/components/interfaces/Database/Replication/DestinationPanel/DestinationForm/index.tsx, apps/studio/components/interfaces/Database/Replication/CreatePipeline/PipelineCreationFlow.test.tsx
usePipelineReviewCosts watches publication and table-selection state and queries estimates for valid selections. The review and destination form use its result. The initial estimate loading state disables starting; estimate errors display an unavailable message. Tests cover pending, failed, and cached estimates.
Validation feedback and navigation
apps/studio/components/interfaces/Database/Replication/CreatePipeline/usePipelineCreationSubmission.ts, apps/studio/components/interfaces/Database/Replication/CreatePipeline/PipelineCreationFlow.tsx, apps/studio/components/interfaces/Database/Replication/CreatePipeline/PipelineDestinationReview.tsx, apps/studio/components/interfaces/Database/Replication/CreatePipeline/PipelineDataReview.tsx, apps/studio/components/interfaces/Database/Replication/CreatePipeline/PipelineCreationFlow.test.tsx
Submission exposes destination and pipeline failures separately. The review panels display the related failures, and the flow scrolls to the connection section when destination failures exist or the data section otherwise. Tests cover failure placement and blocked creation requests.

Users can start a pipeline before its initial cost estimate appears. Restore that safeguard before merging, while continuing to allow submission if the estimate fails.

- Around line 185-192: Keep the role="status" live region persistently mounted
in the PipelineCostEstimate component, and conditionally render the Admonition
message inside it only when loading has finished and isError or estimate ===
undefined. Preserve the existing message, styling, and ability to start the
pipeline.
- Line 70: Update the estimate rendering conditions in PipelineCostEstimate so
fallback states depend only on estimate === undefined, preserving cached
estimates when a background refetch fails. Apply this at both estimate display
checks, and remove the now-unused isError prop and related references unless a
separate refresh-failure hint is intentionally retained.

- Around line 219-230: Keep the submission-failure status region mounted
throughout the review step by wrapping the conditional Admonition in a
persistent div with role="status". Remove role="status" from the Admonition
itself, while preserving the existing submissionFailures condition, message
text, styling, and severity selection.

just a side thought - wondering if this copy needs to consider warnings as well

nit but i reckon we should make the naming here consistent

maybe just showLoadError instead of showPublicationLoadError?
