changed the title
PipelineRuns that fail late currently have to restart from the beginning. This repeats successful work and can repeat non-idempotent side effects. This TEP proposes an alpha-gated way to create a new PipelineRun from an unsuccessful previous PipelineRun and restart at a selected task. Completed upstream task outcomes and results are inherited while the new run preserves graph dependencies and records the relationship between both attempts. The proposal stays high-level and includes a conceptual YAML example. It calls out the remaining questions around pipeline compatibility, workspaces, matrix and finally tasks, authorization, retention, and Chains/SLSA provenance.

Summary
This TEP proposes an alpha-gated way to create a new
PipelineRunthat resumes from a task in an unsuccessful source run. Completed upstream task outcomes and results are inherited without re-executing those tasks, while the new run preserves Tekton's graph semantics and records the relationship between both execution attempts.The proposal stays high-level and identifies the remaining design questions around pipeline compatibility, workspace state, authorization, retention, branching graphs, and Chains/SLSA provenance.
