docs: SDK v0.53 to v0.54 migration checklist for PoA#35
Conversation
Summary of ChangesHello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request introduces a critical new documentation asset: a comprehensive migration checklist for upgrading Regen Ledger from Cosmos SDK v0.53 to v0.54, with a strong focus on integrating the native x/poa module. The document serves as a bridge between high-level mechanism specifications and the practical engineering steps, outlining technical assessments, integration procedures, a phased migration plan, risk management strategies, and coordination efforts. Its purpose is to provide a clear, actionable roadmap for the upcoming major network upgrade, ensuring all stakeholders understand the 'how' and 'when' of the implementation. Highlights

Code Review
This pull request introduces a comprehensive migration checklist for upgrading to Cosmos SDK v0.54 and integrating the x/poa module. The document is well-organized, covering key aspects from technical assessments to risk management. My review focused on the logical consistency of the plan and its alignment with the referenced mechanism specifications. I've highlighted a critical issue in the migration sequence where a module dependency is violated, which could prevent validator compensation, aligning with the rule on specifying transition logic between mechanisms. I also provided suggestions to improve the clarity and consistency of the dependency and reference sections, in line with the rule for improving document clarity. Addressing these points will strengthen this important planning document.
| ## Migration Sequence | ||
|
|
||
| ``` | ||
| Phase A: SDK Upgrade (no consensus change) | ||
| 1. Upgrade SDK v0.53 → v0.54 | ||
| 2. Upgrade CometBFT v0.38 → v0.39 | ||
| 3. Upgrade IBC-Go v10 → v11 | ||
| 4. Add x/poa module (inactive) | ||
| 5. Test on regen-upgrade testnet | ||
| 6. Governance proposal for mainnet upgrade | ||
|
|
||
| Phase B: Consensus Migration | ||
| 1. Activate x/poa with seed validator set | ||
| 2. Begin delegation wind-down period | ||
| 3. Disable new x/staking delegations | ||
| 4. Existing delegations unbond (21-day period) | ||
| 5. Deactivate x/staking rewards | ||
| 6. Monitor IBC channel health throughout | ||
|
|
||
| Phase C: Economic Integration | ||
| 1. Deploy M013 fee routing (CosmWasm or native) | ||
| 2. Configure fee → burn/validator/community splits | ||
| 3. Activate M012 supply algorithm | ||
| 4. Deploy M015 contribution tracking (later phase) | ||
| ``` |

The proposed Migration Sequence has a critical dependency flaw. Phase C plans to deploy M013 (fee routing) after Phase B activates x/poa (PoA/M014).
However, the mechanism specification (phase-2/2.6-economic-reboot-mechanisms.md, lines 467 and 719) states that M014 requires M013 for validator compensation. Activating PoA without the fee routing mechanism would leave validators uncompensated.
Please revise the migration sequence to ensure M013 is deployed and active before or concurrently with the PoA consensus migration in Phase B.

- When specifying transition logic between different mechanisms (e.g., multipliers), explicitly define the function (e.g.,
max()) and the state-based conditions (phase-gating) that govern the transition to prevent implementation ambiguity.

This table lists the finalization of the M013 and M014 specs as separate dependencies, which can be confusing since they are part of the same specification document. To improve clarity, consider combining them into a single item that reflects their shared origin.

The same specification file is listed twice for the M013 and M014 specs. Since this document's purpose is to connect specs M012–M015 to the engineering work, and all these specs are in the same file, it would be clearer and more concise to use a single, comprehensive reference to the mechanism specification document.

| - M013 spec: `phase-2/2.6-economic-reboot-mechanisms.md` | |
| - Mechanism Specs (M012-M015): `phase-2/2.6-economic-reboot-mechanisms.md` |

Summary
Adds
docs/sdk-v054-migration.md— a concrete engineering checklist connecting M012-M015 mechanism specs to the actual Regen Ledger upgrade path.Why This Matters
The mechanism specs tell us what to build. This document tells engineering how and when — with a concrete checklist, risk matrix, and dependency map. Without this, there's no bridge from specification to implementation.
