FWSS M4.2 Contract Upgrade

[BigLep]

This is a tracking issue for work items that need to be completed before we can update the FWSS contract for M4.2. This should involve a change to the FWSS contract without needing to deploy a new proxy (i.e., this is non-breaking changes):

• Fix FWSS per-byte over-charging #451
• Charge floor price even if zero data #458
• PDPVerifier upgrade from v3.3.0 to v3.4.0 pdp#271
• PDPVerifier upgrade from v3.3.0 to v3.4.0 pdp#271
• FWSS portions of Per-operation pricing for FilecoinWarmStorageService #469
  • feat: operational pricing #488
  • feat(pricing): add getPriceList() for full on-chain price discovery #501
• FWSS support for simplified DataSet terminations and cleanup for GA #484
• FWSS portion of Set addPieces batch limits and adjust pricing #496
• fix(abandonment): unblock finalize settle past open proving period #512
• Test pricing, termination, and calldata limit contract+client changes in devnet foc-devnet#113

I removed #457 from the list, since the milestone for that ticket has moved to M4.5

[BigLep]

@rvagg : I added #458 and #465 to the list. Please correct if that is wrong.

[BigLep]

#466 has replaced #465

@rjan90 : lets make sure we're tracking this week what is needed to execute on this. I assume we need to add a PDP deployment for FilOzone/pdp#269

2026-05-26 discussion notes:

• PDP change for cleanup deposit feat: cleanup deposits pdp#270
  • This has been staged
  • It needs to be coordinated with Curio changes?
    • PDP: Update pdpv0 termination cleanup state machine for PDPVerifier cleanup mode filecoin-project/curio#1236
    • Ways to know which version of contract?
      • Can look at contract version spring
• version gating is needed on the cleanup side?
• Mayank walking through the open PRs
• General agreement on squencinc:
• Curio PRs merge into main first then execute PDP upgrade
• But we have the wrinkle of needing a pdp change for PDP: Update pdpv0 termination cleanup state machine for PDPVerifier cleanup mode filecoin-project/curio#1236 (comment)
  • PR is coming
  • I'm not sure how that fits int PDPVerifier upgrade from v3.3.0 to v3.4.0 pdp#271

I'll edit this more once we finish the conversation after 2026-05-26 weekly
