fix(platform): record the genesis fee generation and add replay coverage across a fee-version boundary

[DCG-Claude]

Issue being fixed or feature implemented

Part 1 of 2 for R05-05 (smart-contract plan #4626, workstream issue #4689, preparation package #4675): repair fee-version registration and historical refund lookup, and add replay coverage across a fee-version boundary, before the infrastructure work merges.

Two gaps on the current tree:

• A second fee generation has no coverage. No shipped schedule carries a fee_version_number other than 1, and the number-1 arm of consume_to_fees_v0 never reads the fee history. The registry lookup, the epoch-change hook, the saved-state round trip and the history-driven refund path are therefore untested for any generation that is not the first.
• The genesis generation is not recorded. PlatformState::default_with_protocol_versions started with an empty fee history and the epoch-change hook only records a generation on the first non-genesis epoch change. On a network whose genesis schedule is not generation 1, bytes stored in epoch 0 would be refunded at generation 1 rates forever, because the lookup falls back to the first registered generation below the earliest entry.

Refs #4675
Refs #4689

What was done?

A fee generation that exists only under mock-versions (packages/rs-platform-version/src/version/mocks/fee_doubled_storage_test.rs): TEST_FEE_VERSION_DOUBLED_STORAGE is FEE_VERSION3 (the latest shipped schedule) with a new fee_version_number in the shifted test range ((1 << TEST_PROTOCOL_VERSION_SHIFT_BYTES) + 1) and a doubled storage_disk_usage_credit_per_byte (54 000). Processing, hashing, signature and vote resolution rates are unchanged, so any fee difference across a boundary into it is storage, and a refund priced at the wrong generation is off by exactly a factor of two.

A mock protocol version on the latest shipped tables (mocks/v4_test.rs): TEST_PLATFORM_V4 is PLATFORM_V14 with that schedule. An upgrade from the latest version to it changes nothing but the fee generation; no migration in perform_events_on_first_block_of_protocol_change fires. It is registered as the third entry of DEFAULT_PLATFORM_TEST_VERSIONS (protocol_version.rs), which the two get_or_init sites and the system-limits mock test now share.

Shifted-range fee lookup (version/fee/mod.rs): under mock-versions, FeeVersion::get and get_optional resolve a number with the test bit set by number in TEST_FEE_VERSIONS and return UnknownVersionError when it is absent. The production arm, FEE_VERSIONS, first, latest and as_static are untouched; a production build rejects a persisted number in that range.

Genesis fee generation recorded (packages/rs-drive-abci/src/platform_types/platform_state/mod.rs): default_with_protocol_versions seeds previous_fee_versions with (GENESIS_EPOCH_INDEX, FeeVersion::get(genesis schedule's number)). The value is the registry entry rather than the schedule reference so the in-memory map equals the map after a saved-state round trip. The epoch-change hook (upgrade_protocol_version/v0/mod.rs) is unchanged; a comment records that its empty-map branch remains for saved states created before the entry was recorded.

Test helpers (execution/validation/state_transition/state_transitions/mod.rs): process_state_transitions_with_platform_version, setup_identity_with_system_credits_with_platform_version and setup_identity_with_platform_version; the existing helpers delegate with PlatformVersion::latest().

Strategy harness (tests/strategy_tests/strategy.rs, execution.rs): ChainExecutionOutcome gains state_transitions_per_block, the transitions the strategy submitted per block, so a test can prove two runs executed one workload. Existing destructurings use ...

Tests

• platform-version, version/fee/mod.rs: the test generation resolves only through the shifted range (an unregistered shifted number is an error, the production registry carries no shifted number); the test generation equals the latest schedule except for the doubled disk usage rate.
• drive-abci, platform_state/mod.rs (mod fee_history): a fresh state records the genesis generation for the latest version and for the mock; a state carrying the test number round-trips through serialize_to_bytes and versioned_deserialize_trusted with every KnownCostItem at epochs 0 to 5 preserved.
• drive-abci, upgrade_protocol_version/v0/mod.rs: an epoch change within the same generation leaves the seeded map at one entry.
• drive-abci, block_processing_end_events/tests.rs (mod fee_generation_boundary), each run through process_raw_state_transitions with the state's fee history and compared to the same workload under PlatformVersion::latest(): bytes stored in epoch 2 after the doubled generation activated and removed in epoch 3 refund at the doubled rate; bytes stored in the genesis epoch of a chain started at the mock and removed in epoch 1 refund at the genesis generation's rate (this fails without the genesis entry, verified by removing the seed locally); a sectioned removal under a non-first generation is rejected with CorruptedCodeExecution without the fee history and priced with it. The stored document's storage flags are read back through query_documents_with_flags so a write that landed in the wrong epoch fails on the flags.
• drive-abci, tests/strategy_tests/test_cases/fee_version_boundary_tests.rs (not ignored; runs on push and nightly through the existing nextest filter): run_chain_upgrade_across_fee_version_boundary_keeps_replay_and_saved_state_in_agreement upgrades from the latest version to the mock (votes in epoch 0, lock-in at block 61, activation at block 121, fee history [(0, 1), (2, doubled)]), split at block 130 plus 30 blocks; run_chain_started_at_a_new_fee_generation_records_the_genesis_generation_and_survives_a_restart starts at the mock (fee history stays [(0, doubled)] across two epoch changes), split at block 70 plus 60 blocks. Each runs the workload (one identity per block, one to two document inserts and one delete per block on the all-mutable DashPay contract) twice, continuously and reopened from the persisted state at the split, with independent_process_proposal_verification on. The runs must agree on the submitted transition bytes after the split, every per-block result code and gas, every identity balance, the fee history and the root hash, and at least one document written before the split (and, for the upgrade, before activation) must be deleted afterwards.

Book: versioning/platform-version.md (mock versions: the test fee generation and the shifted range), testing/strategy-tests.md (workload-preserving continuation and a "Crossing a Fee-Version Boundary" subsection), fees/overview.md (one sentence on when generations are recorded).

Plan review finding, workload-preserving continuation: continue_chain_for_strategy reseeds from the given entropy and state_transitions_for_block redeploys any start_contracts left in the strategy at the continuation's first block, so a naive "run, reopen, continue" is a different workload. The harness also puts the deployed contracts back into the strategy after remapping the operations. run_split therefore hands the second segment the first segment's mutated strategy with start_contracts cleared, its identities, signer and nonce counters, and reseeds both runs from the same entropy; equality of the submitted transition bytes is asserted before the root hashes are compared.

Findings for sibling tasks (no code here): the None fee-history callers on this tree (withdrawals/*, add_process_epoch_change_operations/v0, update_masternode_identities/v0 at init chain) only remove unflagged elements and cannot trip the non-first-generation guard today; the shifted test range is what a tooling "reject unknown fee versions" check must also reject outside test builds; the first protocol version that ships a schedule with a new number needs no further registration code, only the mock base moved to its table; fee-history values may be schedule references (hook) or registry entries (seed, reload) and agree on every KnownCostItem, so a typed owner encoding must not depend on pointer identity.

How Has This Been Tested?

Local gate (macOS, Rust 1.92, exit codes captured in ~/dashvm/runs/R05-05/):

cargo fmt --all -- --check
cargo clippy -p platform-version -p dpp -p drive -p drive-abci --all-features --all-targets -- -D warnings
cargo check --workspace --all-targets
cargo test -p platform-version --features mock-versions
cargo test -p drive-abci platform_types::platform_state
cargo test -p drive-abci protocol_upgrade::upgrade_protocol_version
cargo test -p drive-abci block_processing_end_events::tests
cargo test -p drive-abci --test strategy_tests fee_version_boundary
cargo test -p drive-abci --test strategy_tests upgrade_fork_tests::tests::run_chain_quick_version_upgrade
cargo test -p drive-abci --test strategy_tests basic_tests::tests::run_chain_stop_and_restart

All exit codes 0. Formatting clean; clippy on the four touched crates with all features and all targets and warnings as errors clean; workspace check with all targets clean. Tests executed (every name checked in the logs, none filtered out): platform-version 23 passed with mock-versions including the two new registry tests and the mock-limits test over the three mocks; platform_types::platform_state 5 passed (the three fee-history tests); upgrade_protocol_version 8 passed (the new same-generation test and the existing empty-map test); block_processing_end_events::tests 9 passed (the three boundary vectors and the six existing refund tests); the two boundary simulations passed in 21 s together; run_chain_quick_version_upgrade and run_chain_stop_and_restart passed, so the extended mock registry and the genesis seed did not disturb the existing upgrade and restart simulations.

Negative checks run locally and reverted: with the genesis seed removed, should_refund_genesis_epoch_bytes_at_the_genesis_fee_generation_rate fails on the fee-history assertion and, with that assertion also removed, on the refund arithmetic (a refund of 11 095 150 credits where 22 191 420 is expected), so the vector observes the seed and not only the map shape.

Breaking Changes

None observable. The genesis seed changes the fee history of a freshly initialised chain from {} to {0 -> registry entry of the genesis schedule's number}. Every existing network (mainnet, testnet, every devnet) has genesis generation 1, FeeVersion::get(1) is FEE_VERSION1, and an empty map resolves every epoch to FeeVersion::first(), the same constant; so every KnownCostItem lookup, every refund and every root hash is identical before and after the change for every reachable input. The fee history lives in the saved platform state (GroveDB aux), not in the merkelised tree, so the extra entry does not touch the app hash. Existing saved states are untouched because init chain does not rerun; the hook's empty-map branch still covers them. The first network whose genesis schedule carries a new number is the boundary at which the seed becomes observable, and it is correct from block 1 there. Production registries and every shipped PLATFORM_V* are byte-identical; no new vN generation, no consensus error, proto, SDK or FFI change.

Decisions taken (provisional values)

• Test-only generation instead of renumbering FEE_VERSION2: the number keys storage-refund behaviour and storage rates never changed, so renumbering would move protocol versions 9 to 14 onto the history-driven path in shipped code.
• Genesis seed in the unversioned state constructor with the unobservability argument above, not behind a new init_chain generation: there is no unreleased protocol version on this tree to gate it on, and the change has no reachable observable effect on existing networks.
• Mock base is PLATFORM_V14 and must move to the newest shipped table when a protocol version is introduced (doc comment on TEST_PLATFORM_V4).
• Doubled storage rate only (54 000, twice FEE_STORAGE_VERSION1); the value is a test constant, not a provisional protocol number.
• Boundary strategy tests sign chain locks with a distinct chain-lock quorum type (ChainLockConfig::default(), four chain-lock quorums) because the independent validator path verifies the chain lock of every proposal it did not build; the harness only signs locks when the chain-lock quorums are distinct from the validator set.
• Split points: block 130 for the upgrade (nine blocks after activation at 121) and block 70 for the chain started at the mock, 60 blocks per epoch. Both simulations run in about ten seconds each in debug.
• Part 2 (on v5.0-dev, after the storage-epoch refund rule lands) adds the pre-boundary vector that the current refund rule cannot pass and reworks the "increasing fees" test.

📝 Walkthrough

Walkthrough

The change adds mock fee-version support, records genesis fee history, validates generation-aware storage refunds, and adds strategy tests for continuous and reopened chains across a fee-version boundary.

Changes

Fee generation boundary handling

Layer / File(s)	Summary
Mock fee-version registry packages/rs-platform-version/src/version/fee/mod.rs, packages/rs-platform-version/src/version/mocks/*, packages/rs-platform-version/src/version/protocol_version.rs, packages/rs-platform-version/src/version/system_limits/mod.rs, book/src/versioning/platform-version.md	Adds the doubled-storage mock fee generation and TEST_PLATFORM_V4. Mock lookups use the shifted test range without falling back to production versions.
Genesis fee history and epoch updates packages/rs-drive-abci/src/platform_types/platform_state/mod.rs, packages/rs-drive-abci/src/execution/platform_events/protocol_upgrade/upgrade_protocol_version/v0/mod.rs, packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/mod.rs, book/src/fees/overview.md	Platform state records the genesis fee generation. Epoch processing avoids duplicate entries when the generation is unchanged. Test helpers accept an explicit platform version.
Storage refund boundary tests packages/rs-drive-abci/src/execution/platform_events/block_processing_end_events/tests.rs	Integration tests verify doubled storage fees, generation-specific refunds, genesis refunds, and rejection of removals without required fee history.
Continued-chain boundary replay packages/rs-drive-abci/tests/strategy_tests/*, book/src/testing/strategy-tests.md	Strategy tests compare continuous and reopened executions across fee-version changes. Snapshots include submitted transitions, balances, roots, protocol versions, and fee history.

Final validation — Phase 2 only (queue backlog)

Verified the Phase-2 review conclusions against exact head ef12ba0. The genesis registry lookup, feature-gated mock fee generation, saved-state coverage, refund assertions, and workload-preserving restart tests support the reviewers' clean assessment; the activation-crossing assertion also contains the reported fix.

• Triage: normal by gpt-6-astra (effort low) — The production change in PlatformState::default_with_protocol_versions is a small, contained genesis fee-history fix, while the substantial diff consists primarily of mock-only fee versions, test harness extensions, and replay/refund coverage rather than intricate changes to critical runtime behavior.

Rebased onto the current v4.2-dev (force-pushed ef12ba0 to 0e7538f, seven commits preserved, none dropped).

Two upstream changes touched the seam this PR builds on, and I carried the PR's intent across both:

• The mock schedule now derives from FEE_VERSION3. Protocol version 14 moved to a new fee schedule (halved contested name fee) after this branch was cut. TEST_FEE_VERSION_DOUBLED_STORAGE is meant to be the latest shipped schedule plus a doubled storage disk usage rate, so its base moved from FEE_VERSION2 to FEE_VERSION3; the alignment test in version/fee/mod.rs would have failed otherwise. The doubled storage table now uses struct update syntax over FEE_STORAGE_VERSION1, so the new ttl_ephemeral_disk_usage_credit_per_byte rate is inherited unchanged rather than listed field by field.
• The saved-state round trip uses the trusted decoder. Upstream split deserialization into trusted (disk) and untrusted (remote) entry points; the round-trip test calls versioned_deserialize_trusted, the same entry point the node uses for its own saved state.

The only textual conflict was the initial PlatformState literal, where upstream added heavy_fields_dirty: true next to the genesis fee history seed; both fields are kept.

Local gate after the rebase: fmt, clippy with warnings as errors on platform-version and drive-abci (all features, all targets), cargo check --workspace --all-targets, the mock fee generation tests, the platform_state, upgrade_protocol_version and fee_generation_boundary modules, and both fee_version_boundary strategy tests, all green.

Re-review — Final validation — Phase 2 only (queue backlog)

Reviewed the complete diff and relevant fee lookup, initialization, persistence, and replay paths; no actionable in-scope defects were found. The genesis entry preserves existing generation-1 pricing, while the feature-gated mock and workload-preserving restart tests exercise fee-generation boundaries without modifying shipped schedules. Local validation passed platform-version tests with and without mock-versions, platform-state compatibility tests, protocol-upgrade and refund suites, both boundary simulations, existing upgrade/restart regressions, and git diff --check; the worktree remains clean.
