pdpv0: integrate with `main` 💪

[BigLep]

This is the tracking issue for the steps/work involved with integrating the pdpv0 branch back into main. This is about getting pdpv0 co-existing with eveything else in main. It is not about migrating pdpv0 with marketsV2/pdpv1. That can be a separate workstream.

Notes

• 2025-12-03: this hasn't been flushed out yet. For now it is serving as a placeholder that we can reference (and not forget about when doing planning). This will happen as part of pdpv0: make plan for how we'll integrate pdpv0 with main #823
• 2026-03-30: clarified the issue description that this is just about getting pdpv0 to reside in main. Improvements of migrating to marketsv2/pdpv1 are separate/future task.
• 2026-04-27: updated task list with acceptance criteria from pdpv0: integrate with main 💪  #822 (comment)

Tasks

• No regression vs pdpv0 baseline (primary signal: Dealbot)
  • Dealbot performance shows no material degradation compared to the current pdpv0 branch
  • No functional regressions observed in:
    • proving
    • onboarding
    • retrieval
• Core functionality verified (manual checks) - These confirm that the system is behaving correctly beyond automated signals.
  • Proofs are successfully generated and submitted
  • Submitted proofs are accepted without errors
  • No unexpected failures in the proving → verification flow
  • Can onboard data
  • Can serve retrievals
• Use all approved Calibration SPs to gather confidence
  • All approved Calibration SPs should move to main for this validation period
  • This provides a broader confidence signal than testing against only one or two nodes
• Sustained stable behaviour
  • No issues observed over a continuous ~3 day period
  • Under ongoing Dealbot activity
  • No new persistent or repeating error patterns
  • Address issues/bugs
    • pdpv0-in-main: message sending is stuck #1134
• Test on mainnet
  • Create release (if needed from new fixes)
  • Have non-endorsed SPs update to RC
  • Confirm no issues for 24 hours.
  • Have endorsed SPs update to RC
  • Confirm no issues for 24 hours
• Bring over docs changes
  • To be done once all the doc changes are complete in pdpv0 branch (e.g., pdpv0: document filecoin pay settlement  #979)
• Bring over any new commits from pdpv0 that hadn't landed in main
  • Log the git commands that were run to confirm not missing anything
• Make pdpv0 read only
• (bonus) Address task scheduling between PoRep and PDP: Task Starvation #1137
