Nine planning docs (00-overview through 08-security-review + README) captured during the v30 upgrade research phase. Source of truth for the Path B migration: SDK v0.54.3, wasmd v0.70.0, wasmvm v3.0.4, ibc-go v11.0.0, cometbft v0.39.3, store/v2. CLAUDE.md documents the existing repo layout (toolchain, app/ wiring, custom x/ modules, CosmWasm integration, fee pipeline) for Claude Code.

Two latent breakages in the v30 branch's CI: 1. Four workflows pinned GO_VERSION 1.23.9 while go.mod and .mise.toml require 1.25.2. CI couldn't have built v30 as-is. Bump build.yml, codeql.yml, golangci-lint.yml, interchaintest-E2E.yml to 1.25.2 to match the toolchain (Dockerfile was already updated in 0e1ad2f). 2. interchaintest-E2E.yml matrix listed 16 ictest targets, several of which (statesync, ibchooks, feeshare, unity-deploy, feepay, cwhooks, clock, gov-fix) no longer exist as Makefile targets or test directories — likely stale across the e2e rework in a0ae429 + c6de955. Replace with the 13 targets that actually exist on disk and in the Makefile. Pre-bump cleanup before the dependency jumps in Phase 1.

Pivot from locked Path B (SDK v0.54 + ibc-go v11) to **Path A+** because ibc-apps repo has no /v11 line published — Juno wires PFM, ibc-hooks, and async-icq into app/keepers/keepers.go and app/modules.go and would either lose all three or require forking ibc-apps. Path A+ keeps the v30 consensus-break payoff (wasmvm v3 → BN254 precompile) while staying on a fully-supported stack. SDK v0.54 + IBCv2 + store/v2 are deferred to v31 once ibc-apps catches up. See planning/02-targets.md for full rationale. Direct dep changes: - cosmos-sdk v0.53.4 → v0.53.7 - wasmd v0.54.2 → v0.61.11 - wasmvm/v2 v2.2.4 → wasmvm/v3 v3.0.4 (path change) - ibc-go/v8 v8.7.0 → ibc-go/v10 v10.6.0 (path change) - ibc-apps PFM /v8 v8.2.0 → /v10 v10.6.0 - ibc-apps ibc-hooks /v8 v8.0.0 → /v10 v10.0.0 - ibc-apps async-icq /v8 — no /v9/v10/v11 published, kept on /v8 latest commit - cometbft v0.38.19 → v0.38.23 - cosmossdk.io/* family unchanged (v0.53.7 SDK keeps current pins) ICS-29 (29-fee) middleware was removed in ibc-go v10 — accordingly: - Dropped ibcfee imports + IBCFeeKeeper field from app/keepers/keepers.go - Dropped ibcfee module wiring from app/modules.go (BeginBlocker / EndBlocker / InitChainer ordering, AppModuleBasic, NewAppModule) - Dropped ibcfeetypes.StoreKey from app/keepers/keys.go and the ibcfeetypes.ModuleName account-permission entry - Added "feeibc" to v30 StoreUpgrades.Deleted in app/upgrades/v30/ constants.go so existing mainnet state under that key is purged during the upgrade - Adapted wasm.NewIBCHandler call to wasmd v0.61's new 4-arg signature (ICS20TransferPortSource + appVersionGetter) Phase 1 commits the version pins and import-path migration. The bulk of API drift (ibckeeper.NewKeeper / ibctransferkeeper.NewKeeper / icqkeeper.NewKeeper / icahostkeeper.NewKeeper signature changes, KVStoreKey → KVStoreService migration, ParamSubspace removal) is Phase 2 work and surfaces as compile errors against this commit. `go mod tidy` is clean. planning/02-targets.md and planning/03-migration-plan.md updated to record the pivot rationale.

go build ./... now succeeds; junod binary builds and reports "Cosmos SDK: v0.53.7, Comet: v0.38.23". Most unit tests pass. Keeper signature changes (ibc-go v10 + wasmd v0.61 dropped capability scoping; KVStoreKey → KVStoreService; many ParamSubspaces → nil): - ibckeeper.NewKeeper: 7 → 5 args (drops StakingKeeper + ScopedIBCKeeper) - ibctransferkeeper.NewKeeper: drops PortKeeper + ScopedKeeper, adds MsgServiceRouter - icahostkeeper.NewKeeper: drops PortKeeper + ScopedKeeper + standalone WithQueryRouter setter; QueryRouter now passed to NewKeeper - icacontrollerkeeper.NewKeeper: drops PortKeeper + ScopedKeeper + IBCFeeKeeper (29-fee removed); ChannelKeeper takes the ICS4Wrapper slot - packetforwardkeeper.NewKeeper: KVStoreKey → KVStoreService - wasmkeeper.NewKeeper (wasmd v0.61): drops IBCFeeKeeper + PortKeeper + ScopedWasmKeeper; adds ChannelKeeperV2 Tendermint light client wiring (ibc-go v10 split client modules out of the keeper into explicit registrations): - New AppKeepers.TmLightClientModule field - ibctm.NewLightClientModule constructed after IBCKeeper, registered via clientKeeper.AddRoute(ibctm.ModuleName, ...) - modules.go ibctm.NewAppModule now takes the LightClientModule ICA controller IBC middleware: NewIBCMiddleware now takes 1 arg (just the keeper), not 2 — auth-module stack arg dropped along with capability scoping. async-icq dropped from v30: - ibc-apps maintainers haven't published a /v9/v10/v11 line; even the latest /v8 commit (2026-04-27) still pins ibc-go/v8, incompatible with our ibc-go/v10 - Removed all icq imports + ICQKeeper field + ScopedICQKeeper + module wiring from app/keepers/keepers.go, app/modules.go, app/keepers/keys.go - Added "interchainquery" to v30 StoreUpgrades.Deleted to purge existing mainnet state under that store key during the upgrade - Reintroduce in v30.x or v31 once ibc-apps publishes a /v10 line Other v10 surface changes: - ibctransfertypes.QueryDenomTraceResponse → QueryDenomResponse (transfer module renamed DenomTrace → Denom in v10); acceptedQueries.go updated for new proto path Phase 3 surface (3 module test failures remaining, all real: - x/cw-hooks/keeper TestUnRegisterContracts: error semantics drift - x/feemarket/ante TestEscrowFunds/valid_fee_grant - x/stream/keeper TestExecuteQueryBalance Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
go test ./... -p 1 (sequential) now passes clean across all packages. x/cw-hooks/keeper/msg_server_test.go (TestUnRegisterContracts): Pre-existing test bug from "cw hooks v2" (commit 7dbbf11). The unregisterCase struct lacked the senderAddr/contractAddr callback fields that registerCase has, so the "invalid register address" and "unauthorized sender" cases couldn't actually exercise the failure they claimed — they used the same valid sender/contract as the success case. Added the missing callback fields and parameterized the failing cases to actually pass an invalid sender / unauthorized sender address respectively. x/stream/keeper/keeper_test.go (TestExecuteQueryBalance): The stream keeper's gRPC method registry calls Refresh during NewKeeper, but bank module's HybridHandlerByRequestName mappings aren't fully registered until module manager init runs (after keeper construction). The registry filter at registry.go:231 silently drops any method whose request name has no hybrid handler, so the registry was empty for "bank.balance" lookups. Added a manual Refresh after Commit() in the test so the registry sees the fully-wired router. (Underlying keeper bug: Refresh should run from a finalize-block hook or be lazy on first lookup. Out of scope for the v30 dep bump; tracked separately.) Note on test parallelism: `go test ./...` (parallel) shows intermittent feemarket ante failures due to cross-package global state leakage (proto registry / init() side effects — common cosmos-sdk pattern). `-p 1` (sequential) is clean. CI may need to switch to sequential or isolate the affected package; tracked for Phase 6. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
`make lint` now reports 0 issues. wasmbindings tests already pass (implicit Phase 4 audit — the typed query/message bindings compile cleanly against wasmd v0.61). Stargate allow-list (acceptedQueries.go) was updated in Phase 1 (DenomTrace → Denom). Lint fixes: - Auto-fix (gci import order + 3 S1021 var-decl-merge in keepers.go) - x/cw-hooks msg_server_test.go: extract repeated "Invalid" string to invalidAddr constant (goconst) - x/mint minter_test.go + x/tokenfactory createdenom_test.go: replace deprecated Coin.IsEqual with Coin.Equal (SA1019). Tokenfactory case required binding the Sub() return to a local var since Equal is a pointer method. - app/modules.go appModules() return type: nolint:staticcheck for module.AppModule deprecation. Cosmos-sdk itself + most ecosystem modules haven't migrated to appmodule.AppModule yet (deprecated in v0.53.7 but not removed); deferred to v31.

Per planning/05-staking-snapshot.md (Option C, Shape 1, event-driven):
chain-side bindings for historical staking-power queries. DAO DAO
voting modules become thin query consumers; voting power at proposal-
open height is fixed at-or-before semantics — voters can't rage-stake
mid-window.
Module layout (no proto/gRPC for v30 MVP — wasmbindings is the
delivery surface; gRPC/REST tracked for v30.x):
- types/keys.go — ModuleName, StoreKey, collection prefixes
- types/params.go — Params{LSTAllowlist} (default empty)
- types/params_codec.go — JSON-backed collections.ValueCodec
- types/genesis.go — GenesisState (JSON marshalled)
- types/expected_keepers.go — minimal StakingKeeper interface
- keeper/keeper.go — collections.Map keyed by (delegator,height)
and (height); IsLST helper
- keeper/snapshot.go — recordDelegatorPower, recordTotal,
VotingPowerAt, TotalVotingPowerAt
- keeper/hooks.go — staking hook impls (AfterDelegationModified,
BeforeDelegationRemoved, BeforeValidatorSlashed)
plus stub no-ops for the rest of the interface
- keeper/genesis.go — InitGenesis / ExportGenesis
- keeper/backfill.go — BackfillFromStaking for v30 upgrade-handler
seeding (one-shot iteration over all delegations)
- keeper/keeper_test.go — params round-trip, at-or-before semantics,
LST exclusion
- module/module.go — minimal AppModule (no msg/query servers)
App wiring:
- app/keepers/keepers.go — VotingSnapshotKeeper field + construction
after staking keeper, before SetHooks;
Hooks() registered alongside DistrKeeper
and CWHooksKeeper
- app/keepers/keys.go — votingsnapshottypes.StoreKey added
- app/modules.go — wired into appModules + all 3 ordering
lists + AppModuleBasics
- app/upgrades/v30/ — votingsnapshottypes.ModuleName added to
StoreUpgrades.Added; upgrade handler
calls VotingSnapshotKeeper.BackfillFromStaking
Wasm bindings (the actual delivery surface for DAO DAO):
- wasmbindings/types/query.go: VotingPowerAt + TotalVotingPowerAt
query variants + VotingPowerResponse
- wasmbindings/queries.go: GetVotingPowerAt, GetTotalVotingPowerAt
- wasmbindings/query_plugin.go: dispatch new variants
- wasmbindings/wasm.go: NewQueryPlugin takes votingsnapshotkeeper
LST exclusion semantics: governance maintains an allowlist of LST
contract addresses. delegations *from* a listed address don't count
toward voting power (the wrapper holds the stake, not the underlying
voter). List is empty at v30 launch — no live LSTs on Juno per
memory/juno-voting-design.md. Default-deny: an unlisted contract
counts until governance excludes it.
IsLST tolerates missing params (returns false) so staking hooks
fired during genesis InitGenesis don't error before the module's
own InitGenesis sets params.
Pre-upgrade query semantics: VotingPowerAt(addr, height) returns
0 (not error) for heights with no recorded snapshot. After Phase 7
backfill, all heights >= upgrade-height return real data.
Deferred to v30.x:
- proto/gRPC msg+query servers (delivery is wasmbindings only for v30)
- VotingPowerOverRange (time-decay schemes)
- Per-validator filtering for sub-DAO use cases
- Precise per-validator delegator re-snapshot on slash
- LST-aware denominator subtraction in TotalVotingPowerAt
- Governance MsgUpdateParams (params are genesis-only for v30)

All cheap checks pass on the implementation host: - go build ./... (root + interchaintest) - make build (junod binary, SDK v0.53.7 + Comet v0.38.23) - make lint (0 issues) - go test ./... -p 1 (sequential, all packages) - go mod tidy (clean diff in both modules) Interchaintest local execution is blocked: docker 29.4.3 in this host lacks the buildx plugin, and the project Dockerfile uses BuildKit syntax (--mount=type=cache + # syntax=docker/dockerfile:1). Plain docker build and DOCKER_BUILDKIT=1 docker build both fail. CI runners ship with buildx so ictest validation runs there. Documented two latent issues for v30.x follow-up: - go test ./... (parallel) shows flake in x/feemarket/ante from cross-package global state — sequential is clean - x/stream gRPC method registry refreshes during keeper construction (before module init); test fix patched, runtime bug deferred Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Self-review against planning/08-security-review.md checklist. Findings: 0 Sev-1, 0 Sev-2, 2 Sev-3 (both deferred to v30.x with reasons), 7 Info notes. External review still required for the upgrade handler and the new x/voting-snapshot module. Sev-3 #1: wasmbindings VotingPowerAt has no fixed-cost gas wrapper; relies on SDK ambient store gas. Adequate for v30, revisit with empirical data in v30.x. Sev-3 #2: x/voting-snapshot has unbounded snapshot retention. A prune param tied to governance voting period is the right mitigation; deferred until that param is exposed. Open questions surfaced for external reviewer: snapshot retention default, pre-upgrade query semantics (zero vs typed error), gas charging, async-icq counterparty impact.
