chore(deps)!: bump dashpay/platform to v4.2-dev (01d94479) - #990
Conversation
Commit byte fixtures written by crates.io bincode 2.0.1 (platform pin 63cf57f4) for QualifiedIdentity (every PrivateKeyData variant and PrivateKeyTarget, voter/operator identities, contract bounds, a WalletDerivationPath with all ChildNumber kinds), ContestedName, TokenConfiguration (with a perpetual DistributionFunction), StoredSeedEnvelope and WalletMeta (serde path). All values are synthetic. Each guard decodes its fixture through the production reader, compares the value, re-encodes byte-for-byte and checks that the fixture tells the standard and legacy encodings apart. This is the executable guard for the upcoming grovedb-bincode switch. Derive PartialEq on ContestedName and Contestant for the comparison. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Move dash-sdk, rs-sdk-trusted-context-provider, platform-wallet and platform-wallet-storage from 63cf57f4 to 01d94479 (4.2.0-dev.10). Transitively: rust-dashcore e4208c90, GroveDB 6.0.0, grovedb-bincode 2.1.0. - Alias bincode to grovedb-bincode =2.1.0: upstream dpp, platform-value and dashcore implement its Encode/Decode traits. On the ordinary paths DET uses, its wire format matches bincode 2.0.1. The pre-bump fixtures confirm it, so no migration is needed. - Use the untrusted dpp decoders (#4625) for pasted state transitions and contracts, and for saved contracts. - Pass the active PlatformVersion to rewards_in_interval_with_explanation (#4645). - Map PlatformWalletError::ShieldedIdentityDebitPending, ShieldedRecoveryCorrupted and ShieldedRecoveryKeysRequired (#4708) to dedicated TaskError variants with fixed, actionable messages. The upstream reason is never shown to the user. Identity-flow bucketing names them explicitly as Other. - Leave TODOs for the contested DPNS fee label (PV14) and the devnet protocol seed. - Add docs/ai-design/2026-09-14-platform-4.2-dev-bump/upgrade-notes.md. BREAKING CHANGE: new TaskError variants; the bincode dependency is now the grovedb-bincode package. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The ShieldedRecoveryCorrupted message told users to restore wallet data from a backup, but DET has no backup or restore-database flow. Both branches (account known and unknown) now say: make sure you have the wallet's recovery phrase, remove the wallet, then import it again. This recourse really clears the error. Wallet removal runs upstream remove_wallet, which calls unregister_wallet and then purge_wallet. That deletes the wallet's shielded_pending_spends rows, damaged identity-debit guards included, and re-import re-binds and re-syncs from chain. The display test now asserts that action and that no message mentions a backup. Also note in the contested-name fixture module that it guards the derive shape only; contests persist through the serde StoredContestedName record.

Drop the five committed bincode 2.0.1 byte fixtures and their inline guard modules, plus the PartialEq derives on ContestedName and Contestant that only those guards used. The grovedb-bincode wire-compatibility verdict now rests on source-level analysis alone; the Cargo.toml comment and the 4.2-dev upgrade notes say so and no longer cite an executable fixture.

Seed Devnet with protocol version 14.
default_platform_version returns PLATFORM_V12 for Devnet. initialize_sdk passes that value to with_initial_version, which uses the seed verbatim. The pinned SDK defines Devnet's minimum as protocol version 14 and states that lower versions can fail to deserialize Devnet contracts before proof verification allows the ratchet to run. AppContext::platform_version() also remains at version 12 after SDK ratcheting. Select a Devnet-specific platform version that meets min_protocol_version; no later configured source overrides this helper.

Show the active protocol-version contested fee.
At protocol version 14, the required contested-name amount is 0.1 DASH. This label still shows 0.2006 Dash. Read contested_document_vote_resolution_fund_required_amount from the active platform version instead of using a literal.

Final validation — Phase 2 only (queue backlog)
The reviewed findings identify real protocol-version limitations, but both are explicitly documented as deferred work in the PR and are not introduced by the dependency/API changes. The bincode compatibility concern is also an intentional source-level verification decision documented in the PR, so no actionable in-scope findings remain.
Review provenance
Source: reviewer 1: gpt-6-astra (agent: phase2-reviewer, role: general); reviewer 2: gpt-6-astra (agent: phase2-reviewer, role: rust-quality); final verifier: gpt-6-astra (agent: astra-verifier, role: final-verifier)
- Triage:
normalbygpt-6-astra(effort low) — This is a broad dependency and API compatibility update with storage-encoding and wallet error-handling changes, but the diff does not itself alter consensus, funds movement, cryptography, key handling, peer-facing deserialization, or a storage migration. - Phase 1 reviewers: not run (skipped for throughput: 12 PRs queued, above the 10 limit)
- Fresh verifier:
gpt-6-astra— final-verifier; agentastra-verifier - Phase 2 reviewers:

Out-of-scope follow-up suggestions (2)
These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
- Seed Devnet with the platform minimum protocol version — The helper still returns PLATFORM_V12 for Devnet, while the upgraded upstream SDK requires Devnet to start at protocol version 14 for some proved requests. The PR explicitly documents this limitation as deferred platform-integration work, and it affects Devnet development/testing rather than the mainnet or testnet paths changed by this dependency bump.
- Follow-up: Track a separate platform-integration change to select the Devnet-specific minimum protocol version and add an SDK initialization regression test.
- Derive the contested-name fee estimate from the active platform version — The registration screen still displays the hardcoded 0.2006 Dash estimate even though protocol version 14 changes the required contested-name amount. The PR explicitly states that this is deferred and that transaction construction already uses the SDK-computed amount, making this a pre-existing display defect rather than a regression in the dependency/API update.
- Follow-up: Track a separate UI change to obtain the contested-name resolution fund requirement from the active PlatformVersion and cover the v12/v14 display values.

TL;DR: Updates the Dash Platform dependency to its latest development version, and gives a clear, actionable message when a shielded payment's recovery data is damaged.
User story
As a wallet user, I want the app to keep working against the current Dash Platform software, and to get clear instructions if something goes wrong with a shielded payment's saved recovery data, so I know what to do instead of hitting a dead end.
Scenario
Base flow
The app talks to Dash Platform through four pinned dependencies. Those pins were several days behind the latest development branch, and the version in use did not yet handle a couple of new network behaviors correctly.

What was done
dash-sdk,rs-sdk-trusted-context-provider,platform-walletandplatform-wallet-storagefrom63cf57f4to01d94479(v4.2-devHEAD). This is a pure fast-forward on the upstream branch — no commits are lost, 29 are gained. Transitively: rust-dashcoree4208c90, GroveDB 6.0.0,grovedb-bincode2.1.0.grovedb-bincode. Upstream now encodes with a fork ofbincodeunder a different Rust trait identity, which broke compilation against DET's ownbincode 2.0.1-derived types (QualifiedIdentity,IdentityPublicKey,TokenConfiguration, etc.). Fixed by aliasing DET'sbincodedependency togrovedb-bincode = "=2.1.0". This is not a cosmetic dependency swap: DET's wallet-secret envelopes and identity blobs are bincode-encoded on disk, so a wire-format change would corrupt existing user data.bincode 2.0.1output forQualifiedIdentity,ContestedName,TokenConfiguration, the seed envelope and wallet meta), decoded through DET's production readers and re-encoded byte-for-byte as an executable regression guard. QA confirmed those tests were genuinely format-sensitive (flipped one byte, got a hard decode failure, restored, passed again) before this PR was opened. They were removed afterward at the repo owner's request — this PR now states the wire-compat verdict rests on hash-identical function bodies across the trusted/ordinary decode path (encoder, varint, config, decoder, derive-macro codegen) betweenbincode 2.0.1andgrovedb-bincode 2.1.0, documented inCargo.toml's pin comment and the upgrade notes, with no executable fixture in this repo pinning it going forward.#4625: dpp's deserialization traits split intoTrusted/Untrustedpairs. DET's 3 call sites (pasted state transitions, pasted contracts, and DET's own saved contracts) now use theUntrusteddecoder, which accepts everything the old API did under the same config and is the safer default for all three.#4645:rewards_in_interval_with_explanationgained a required&PlatformVersionargument; passed at both call sites.#4708:PlatformWalletErrorgained 3 shielded-recovery variants.
