This commit lays the type and loader scaffolding for the new fork name without touching consumers yet — the gate remains null-by-default so behavior is bit-identical to pre-P2. Changes: - src/forks/forkConfig.ts: - Split ForkConfig into BaseForkConfig + per-fork variants (OsDenominationConfig, GasFeeSeparationConfig) joined as a discriminated union, plus a ForkConfigByName map type for statically-typed per-fork narrowing. - Add gasFeeSeparation to ForkName and DEFAULT_FORK_CONFIG with a PLACEHOLDER_TREASURY_ADDRESS (`0x` + 64 zeros). The placeholder is valid while activationHeight === null; the loader rejects it once a real activation is scheduled. - src/forks/loadForkConfig.ts: - Per-fork validator dispatch via validateForkEntry switch. The gasFeeSeparation validator enforces a strict-lowercase 0x+64-hex treasuryAddress (PR #778 G-1/G-4 lesson on case mismatch) and refuses to seal genesis with the placeholder zero treasury when a non-null activationHeight is set. - New writeForkConfig dispatcher narrows the union per fork name. - primeFeeDistributionFromForkConfig populates SharedState.feeDistribution with the consensus-fixed addresses (burnAddress = code constant, treasuryAddress from fork payload). Distribution percentages remain undefined until loadNetworkParameters folds them in (P13). - Export GAS_FEE_SEPARATION_BURN_ADDRESS constant. Authoritative home moves to migrations/gasFeeSeparation.ts in P12; re-export keeps callers stable. - src/utilities/sharedState.ts: - feeDistribution: FeeDistributionRuntime | null field with the combined view (addresses fork-fixed, percentages governance-driven). - forkConfig typed as ForkConfigByName (narrowed) so callers can read forkConfig.gasFeeSeparation.treasuryAddress without runtime checks. - src/forks/index.ts: - Re-export new types and GAS_FEE_SEPARATION_BURN_ADDRESS / PLACEHOLDER_TREASURY_ADDRESS constants. - testing/forks/: 13 new test cases in loadForkConfig.test.ts covering treasuryAddress validation (missing/non-string/mixed-case/short), placeholder rejection when scheduled, feeDistribution priming behavior, combined-fork scenario, and re-load preservation of governance-folded percentage groups. - testing/forks/*.test.ts (8 files): snapshot type updated from Record to ForkConfigByName so the narrowed per-fork shape round-trips through test setup/teardown. Test suite: 106 pass / 0 fail / 349 expect() calls across testing/forks/. Typecheck clean except pre-existing L2PS breakage inherited via stabilisation merge (not introduced here). --- src/forks/forkConfig.ts | 106 ++++++-- src/forks/index.ts | 13 +- src/forks/loadForkConfig.ts | 239 ++++++++++++++++-- src/utilities/sharedState.ts | 54 +++- testing/forks/amountCanonical.test.ts | 5 +- .../forks/disableForkMachineryFlag.test.ts | 5 +- testing/forks/forkBoundary.test.ts | 5 +- testing/forks/forkGates.test.ts | 5 +- testing/forks/getNetworkInfo.test.ts | 5 +- testing/forks/integration.test.ts | 5 +- testing/forks/loadForkConfig.test.ts | 218 +++++++++++++++- testing/forks/postForkSerializer.test.ts | 5 +- testing/forks/serializerGate.test.ts | 5 +- 13 files changed, 594 insertions(+), 76 deletions(-) diff --git a/src/forks/forkConfig.ts b/src/forks/forkConfig.ts index e7fff871..41c5b70e 100644 --- a/src/forks/forkConfig.ts +++ b/src/forks/forkConfig.ts @@ -1,22 +1,29 @@ /** * Fork configuration registry. * - * P2 of the DEM → OS denomination migration introduces *hard-fork machinery* - * without activating any rule changes.

03/25] feat(forks): gasFeeSeparation state migration + chainBlocks hook (myc#98, DEM-665 P12) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Creates the two consensus-fixed GCR accounts (burn and treasury) that the post-fork fee-distribution logic writes to. Single job per activation: insert zero-balance rows at known addresses, persist a fork_state ledger entry for idempotency. No balance touching — that remains osDenomination's responsibility, and the chainBlocks hook orders osDenomination FIRST so all balances are in OS units by the time gasFeeSeparation creates fresh accounts. Files: - src/forks/migrations/gasFeeSeparation.ts (NEW): runGasFeeSeparation- Migration() + isGasFeeSeparationMigrationApplied() mirror the osDenomination shape. Atomic via caller EntityManager, idempotent via the fork_state row. Defence-in-depth address validation (lowercase 0x + 64 hex, reject burn-address-as-treasury) on top of the loader's checks. Raw SQL inserts via portable `placeholder()` helper so the same code runs against Postgres (production) and the sqlite test harness. - src/libs/blockchain/chainBlocks.ts: gasFeeSeparation activation hook inside insertBlock's transaction, immediately after osDenomination. Ordering documented in a comment. Reads treasury from getSharedState.forkConfig.gasFeeSeparation.treasuryAddress (hydrated by loadForkConfigFromGenesis in P2). - src/forks/index.ts: re-export new symbols. - testing/forks/migrations/gasFeeSeparation.test.ts (NEW): 16 tests covering constants alignment (BURN_ADDRESS matches loader mirror), idempotency (fresh DB, after-run, double-run rejection), account creation (burn+treasury at balance 0, result struct), pre-existence handling (don't overwrite seeded burn/treasury), fork_state row shape, defence-in-depth validation (non-string, malformed, mixed case, burn-as-treasury), and coexistence with an existing osDenomination fork_state row. Test suite: 122 pass / 0 fail / 376 expect() calls across testing/forks/ (16 new in migrations/gasFeeSeparation.test.ts; the existing 106 unchanged).

Pre-fork rows carry `null` — the legacy lump-sum gas path has no rpc-routing notion. Files: - src/libs/blockchain/transaction.ts: - Constructor seeds rpc_address: null on freshly-built Transaction objects. - toRawTransaction carries the field across via `rpcAddress`. - fromRawTransaction normalises a missing field (undefined) to the explicit `null` declared by TxFee. - src/model/entities/Transactions.ts: - rpcAddress varchar column, nullable. Matches the convention used by the other hex-address columns (from, to, from_ed25519_address). - src/migrations/AddRpcAddressToTransactions.ts (NEW): - Idempotent ADD COLUMN IF NOT EXISTS. `synchronize: true` already handles new boots; this migration is checked in so production deploys are deterministic. - src/forks/serializerGate.ts: - Post-fork canonical serializer passes rpc_address through unchanged (`fee.rpc_address ?? null`). No numeric coercion — plain varchar. - src/libs/blockchain/chainGenesis.ts + src/libs/blockchain/routines/validateTransaction.ts + src/libs/l2ps/L2PSBatchAggregator.ts + src/libs/utils/demostdlib/deriveMempoolOperation.ts + src/features/InstantMessagingProtocol/signalingServer/signalingServer.ts: Structurally-required `rpc_address: null` added to every TxFee literal the SDK type now demands. Internal Operation.fees blocks (genesis fees, defineGas gas operation) are non-routable and carry `null`. - testing/forks/*.test.ts (5 files): Same `rpc_address: null` injection into TxFee test fixtures so the suite typechecks under the new SDK shape. SDK side: TxFee.rpc_address + RawTransaction.rpcAddress already shipped via the local SDK overlay at node_modules/@kynesyslabs/demosdk (P3 SDK commit landed in /Users/tcsenpai/kynesys/sdks). P9 will publish 4.0.0-rc.1 and bump the package.json pin to drop the overlay. Test suite: 122 pass / 0 fail in testing/forks/ (no regressions). The pre-existing tests/governance/snapshotWeightIntegrity.test.ts failure is unrelated to this commit (verified on a clean stash) and tracked separately. Typecheck clean except pre-existing L2PS breakage inherited via stabilisation merge. --- .../signalingServer/signalingServer.ts | 10 +++- src/forks/serializerGate.ts | 4 ++ src/libs/blockchain/chainGenesis.ts | 4 ++ .../routines/validateTransaction.ts | 2 + src/libs/blockchain/transaction.ts | 16 +++++++ src/libs/l2ps/L2PSBatchAggregator.ts | 1 + .../demostdlib/deriveMempoolOperation.ts | 2 + src/migrations/AddRpcAddressToTransactions.ts | 47 +++++++++++++++++++ src/model/entities/Transactions.ts | 14 ++++++ testing/forks/amountCanonical.test.ts | 1 + testing/forks/forkBoundary.test.ts | 1 + testing/forks/integration.test.ts | 1 + .../forks/migrations/genesisFailLoud.test.ts | 1 + testing/forks/postForkSerializer.test.ts | 4 ++ testing/forks/serializerGate.test.ts | 1 + 15 files changed, 108 insertions(+), 1 deletion(-) create mode 100644 src/migrations/AddRpcAddressToTransactions.ts diff --git a/src/features/InstantMessagingProtocol/signalingServer/signalingServer.ts b/src/features/InstantMessagingProtocol/signalingServer/signalingServer.ts index cae6ba92..03300f9c 100644 --- a/src/features/InstantMessagingProtocol/signalingServer/signalingServer.ts +++ b/src/features/InstantMessagingProtocol/signalingServer/signalingServer.ts @@ -658,7 +658,15 @@ export class SignalingServer { gcr_edits: [], nonce, timestamp, - transaction_fee: { network_fee: 0, rpc_fee: 0, additional_fee: 0 }, + transaction_fee: { + network_fee: 0, + rpc_fee: 0, + additional_fee: 0, + // DEM-665: IM signaling tx is signed client-side; + // a validating node populates rpc_address during + // confirmTransaction (P6). + rpc_address: null, + }, } transaction.status = "" diff --git a/src/forks/serializerGate.ts b/src/forks/serializerGate.ts index 1959e15c..58309ed0 100644 --- a/src/forks/serializerGate.ts +++ b/src/forks/serializerGate.ts @@ -97,6 +97,10 @@ function transformToOsTransactionContent( additional_fee: denomination.toOsString( toOsBigint(fee.additional_fee as number | string | bigint), ) as unknown as number, + // DEM-665: rpc_address is plain varchar — no numeric + // canonicalisation.

Treasury and burn addresses remain immutable fork-payload (see P2). Layer 1 (percentage cap): - New `DISTRIBUTION_MAX_CHANGE_PERCENT = 10` constant. - `withinPercentCap` takes the cap as a parameter; distribution keys use the tighter ±10%, everything else keeps the historical ±50%. Layer 2 (absolute floor/ceiling): - NUMERIC_BOUNDS gains `additionalFee: [0, 5000]` and `*Pct: [0, 100]` for every distribution percentage. Layer 3 (NEW — cross-key sum-100): - `checkDistributionSumInvariant` runs on the merged (current ⊕ proposed) view of each group: network_fee: burnPct + treasuryPct === 100 additional_fee: burnPct + treasuryPct === 100 special_ops: burnPct + treasuryPct + rpcPct === 100 Untouched groups are skipped (they were valid by induction). - First-failing key is returned in the BoundsCheck for diagnostic attribution. Governable set: - PHASE_1_GOVERNABLE_KEYS extended with `additionalFee` and every member of the new `DISTRIBUTION_KEYS` set. Hardcoded fallback: - `HARDCODED_FALLBACK_NETWORK_PARAMETERS` carries the SPEC defaults (50/50, 25/75, 25/50/25) plus `additionalFee: 0`. Mirror exposed through `getGenesisNetworkParameters()`. SharedState mirror: - `loadNetworkParameters` now folds the merged percentages onto `getSharedState.feeDistribution`. Addresses (burnAddress, treasuryAddress) primed earlier by `loadForkConfigFromGenesis` (P2) are preserved — only the percentage groups are overwritten. A governance proposal changing any *Pct takes effect on the next tx without a node restart (P5's feeDistribution.ts dereferences this at call time). Tests: - tests/governance/safetyBounds.test.ts gets a new "DEM-665 distribution-percentage governance" describe block with 9 cases: additionalFee bounds, single-key sum-100 violation, balanced two-key shift within cap, +12% rejection above the 10% cap, ceiling rejection, balanced three-key special_ops rebalance, special_ops merged-sum mismatch, untouched-group skip. Test suite: 31 pass / 0 fail in tests/governance/safetyBounds.test.ts; 237 pass / 1 pre-existing fail (snapshotWeightIntegrity — unrelated mock setup, tracked separately) in testing/forks/ + tests/governance/. Typecheck clean except pre-existing L2PS breakage inherited via stabilisation merge.

Emits the network_fee (burn/treasury), rpc_fee (100% to rpc operator), and additional_fee (burn/treasury) blocks in that order. Components with 0 totals are skipped; an rpcAddress=null but rpcFee>0 situation logs a warning and skips the rpc block (P6 will never leave rpcAddress null in production). - generateSpecialOpsFeeEdits: TLSN. Splits a single total across burn / rpc-operator / treasury per the SPEC default 25/50/25. If the rpc operator address is missing, the unrouted share is folded into treasury so the balance still closes. Consensus-critical rounding: every per-recipient share is Math.floor(total * pct / 100); treasury captures the remainder so the sum of `add` amounts equals the `remove` amount exactly. Number math is safe within OS magnitudes 2^53. Reads `getSharedState.feeDistribution` (populated by loadForkConfigFromGenesis at P2 for the addresses, and by loadNetworkParameters at P13 for the percentage groups). Defensive null guard returns [] + logs error — callers MUST gate on isForkActive("gasFeeSeparation", height) upstream because the helper has no block-height context. Tests: tests/blockchain/feeDistribution.test.ts — 16 cases: - generateFeeDistributionEdits: null guard, zero-component skip, 50/50 network split, 100% rpc routing, null-rpc skip, 25/75 additional split, rounding remainder to treasury, 0%-burn branch, isRollback forwarding, block ordering invariant. - generateSpecialOpsFeeEdits: null guard, totalFee=0, 4-edit SPEC default, rounding remainder to treasury, null-rpc fallback (rpc share folded into treasury), isRollback forwarding. Test suite: 16/16 pass / 44 expect() in tests/blockchain/. Regression: 253/254 pass across testing/forks/ + tests/governance/ + tests/blockchain/ (the 1 fail is the pre-existing snapshotWeightIntegrity mock-setup issue unrelated to DEM-665).

The injection runs BEFORE signValidityData() so the appended edits are part of the signed payload (otherwise peers would diverge). Files: - src/libs/blockchain/routines/validateTransaction.ts: - Import calculateFeeBreakdown (from P4) + generateFeeDistribution- Edits (from P5) + isForkActive (from forks barrel). - New `applyGasFeeSeparation(tx, validityData)` helper: 1. Coerces sender pubkey via forgeToHex (same as defineGas). 2. Calls calculateFeeBreakdown — refuses to proceed on a non-integer / negative total. 3. Resolves this node's signing pubkey + stamps transaction_fee.{network_fee, rpc_fee, additional_fee, rpc_address}. 4. PROD-only: reads GCR.getGCRNativeBalance and rejects if senderBalance < total. 5. Calls generateFeeDistributionEdits and prepends the returned GCREdits onto tx.content.gcr_edits. - Gating: invoked only inside `if (isForkActive("gasFeeSeparation", referenceBlock))`. Pre-fork behaviour is unchanged — the legacy defineGas() path remains the no-op placeholder it has been since the original /* REVIEW */ block disabled the live caller. - On failure (balance, breakdown sanity), validityData.valid is set to false with `[Tx Validation] [FEE ERROR] …` message and returned signed. Test suite: 253/254 pass across testing/forks/ + tests/governance/ + tests/blockchain/ (1 pre-existing snapshotWeightIntegrity mock failure unrelated to this commit). Typecheck clean except pre-existing L2PS breakage from stabilisation merge. P6 is a wiring commit — the new code path is exercised by P10 integration tests (fork-boundary rehearsal scenario) once those land.

Pre-fork the legacy single-remove path is preserved verbatim so re-syncing a pre-fork chain stays bit-identical. Files: - src/libs/blockchain/gcr/gcr_routines/handleNativeOperations.ts: - New ONE_DEM = 1_000_000_000 + getTlsnFees(blockHeight) helper: post-fork scales TLSN_REQUEST_FEE / TLSN_STORE_BASE_FEE / TLSN_STORE_PER_KB_FEE by ONE_DEM (1 DEM = 10^9 OS). Pre-fork leaves them at the legacy "1 DEM = 1 unit" values. - tlsn_request case: branches on isForkActive("gasFeeSeparation", blockHeight). Post-fork builds specialOps edits with rpcAddress pulled from tx.content.transaction_fee.rpc_address (stamped upstream by P6). Pre-fork keeps the original single-remove burnFeeEdit untouched. - tlsn_store case: same fork-branch around the storage-fee edit. Pre-fork single-remove preserved; post-fork specialOps edits routed through generateSpecialOpsFeeEdits. The storage-size math (base + perKB × proofSizeKB) is unchanged — only the per-constant magnitudes scale post-fork. Block height source: tx.blockNumber when present, else getSharedState.lastBlockNumber, defaulting to 0 — same fallback chain other call sites use. When rpc_address is missing on a post-fork tx (defensive case — shouldn't happen because P6 always stamps it), the rpc share is folded into treasury inside generateSpecialOpsFeeEdits so the balance still closes; a warning is logged.

A normal `remove` against this pubkey would re-circulate burned coins, defeating the burn-percentage routing done by P5/P6/P7. This commit refuses such removes inside GCRBalanceRoutines.apply. Carve-outs (both intentional): 1. Rollback flow: GCRBalanceRoutines inverts add↔remove BEFORE the guard runs. A rollback of a prior burn-`add` (which now reads as `remove + isRollback=true`) IS allowed — the carve-out keeps fee distribution reversible. 2. Pre-fork: the guard is wrapped in `isForkActive("gasFeeSeparation", lastBlockNumber)`, so any legacy code path that happens to remove from the zero address pre-fork is unchanged. Address comparison is case-normalised via toLowerCase() on both sides — PR #778 G-1/G-4 lesson (myc#6). Files: - src/libs/blockchain/gcr/gcr_routines/GCRBalanceRoutines.ts: - import isForkActive from "@/forks" - New block placed AFTER the rollback inversion and BEFORE the balance math. Reads getSharedState.feeDistribution + getSharedState.lastBlockNumber. No-op when feeDistribution is null or the fork is inactive. - tests/blockchain/GCRBalanceRoutines.test.ts (NEW): 8 cases covering: • normal remove against burn rejected when fork active • rollback inversion against burn allowed • normal remove against burn allowed pre-fork • remove against non-burn account allowed • add to burn allowed (fee-distribution path) • uppercase-hex edit account still hits the guard (case norm) • null feeDistribution falls through (defensive) • lastBlockNumber < activationHeight falls through (gate) Test suite: 8/8 pass / 10 expect().

Tests cover both branches of tlsn_request and tlsn_store: Pre-fork (legacy path): - tlsn_request emits a single 1-DEM remove (legacy burn-by-omission). - tlsn_store emits a single size-scaled remove (storeBase + perKB). Post-fork (new path): - tlsn_request scales fee to 10^9 OS, emits 4 edits with the SPEC default 25/50/25 burn/rpc/treasury split (250M / 500M / 250M). - tlsn_request with rpcAddress=null folds rpc share into treasury so the balance closes (3 edits: remove + burn + treasury 750M). - tlsn_store scales size-based fee × 10^9 and routes through the same special-ops split; sum invariant verified. Mocks tokenManager so the test runs without a live token store — token shape mirrors the real entity just enough for the handler's status / owner / domain checks. P10 status (full picture): ✅ feeDistribution.test.ts (16 tests, P5) ✅ GCRBalanceRoutines.test.ts (8 tests, P8) ✅ calculateCurrentGas.test.ts extended (5 tests, P4) ✅ safetyBounds.test.ts extended (9 tests, P13) ✅ governanceHandlers.test.ts implicit (GENESIS struct now carries the new keys; existing equality assertion still passes) ✅ handleNativeOperations.test.ts (NEW — this commit) ⏭️ validateTransaction.test.ts — applyGasFeeSeparation is a module-private helper. Direct unit coverage requires either extracting it (architectural decision deferred) or mocking Chain/GCR/forgeToHex/Transaction.confirmTx — heavy surface for a wiring layer already exercised by the component tests above. ⏭️ testing/forks/rehearsal/scenarios/09-fee-distribution.ts + 10-burn-spend-rejection.ts — devnet integration scenarios mirror the P5b rehearsal pattern (myc#22). They need a 4-node Postgres devnet harness and a coordinated boundary-cross run, so they are filed for the rehearsal team to run alongside the existing osDenomination scenarios.

The chainBlocks hook runs them sequentially in the same block; running them on different heights means osDenomination scales balances at one height and gasFeeSeparation creates OS-denominated accounts at another, which is a recoverable but pointless state confusion. +- **Don't manually edit the burn or treasury rows in `gcr_main`.** Burn balance is reachable only via `add` edits (and rollback inversions of those). Treasury balance is governance-mutated indirectly through fee distribution. Manual SQL edits are not consensus-replayed and will desync the validator. +- **Don't propose to change every distribution percentage in one go.** Even though the bounds permit ±10% per proposal, large simultaneous shifts give observers no window to react.

The `applyGasFeeSeparation` helper used to be a module-private function inside validateTransaction.ts; mocking the full confirmTransaction surface (Chain, GCR, forgeToHex, Transaction.confirmTx, every signing helper) to reach it was heavier than the helper itself deserved. Moving it into its own file makes every external dependency jest-mockable in isolation. Files: - src/libs/blockchain/routines/applyGasFeeSeparation.ts (NEW): - Exports `applyGasFeeSeparation(tx) -> Promise<{ ok: true } | { ok: false; message: string }>`. - Same behavior as the inline version: stamps transaction_fee.{network_fee, rpc_fee, additional_fee, rpc_address}, PROD-only balance check, prepends generateFeeDistributionEdits onto tx.content.gcr_edits. - Tighter signature — drops the unused `validityData` parameter the inline version carried. - Re-exports an `ApplyGasFeeSeparationTx` Pick so callers can pass either the SDK Transaction or the node-side subclass. - src/libs/blockchain/routines/validateTransaction.ts: - Imports applyGasFeeSeparation from the new module. - Inline copy deleted; the fork-gated call site at line 131 now invokes the imported helper with `applyGasFeeSeparation(tx)` (one-arg). - Removed `calculateFeeBreakdown` + `generateFeeDistributionEdits` imports — the helper owns them now. - tests/blockchain/applyGasFeeSeparation.test.ts (NEW): 15 tests organised into four describes: 1. happy path — stamps transaction_fee fields, prepends edits, emits 5 edits for 50/50 network + 100% rpc breakdown. 2. sender address resolution — string passthrough, forgeToHex coercion for non-string, error path when forgeToHex throws. 3. breakdown sanity — rejects NaN, Infinity, fractional, negative totals. Drives them via sharedStateStub.networkFee instead of mocking the calculateFeeBreakdown module (bun test does not auto-isolate module mocks across files; mocking calculateCurrentGas here leaked into tests/governance/calculateCurrentGas.test.ts during the full suite run). 4. PROD balance check — accept on >=, reject on <, error path when GCR.getGCRNativeBalance throws, no balance call in non-PROD. Test suite: 281/282 pass / 715 expect() calls across testing/forks/ + tests/governance/ + tests/blockchain/. The 1 fail is the pre-existing snapshotWeightIntegrity Jest-mock setup issue unrelated to DEM-665.

Scenario 10 now submits a real signed tx with a malicious remove-from-burn GCREdit and asserts the consensus-critical invariant (burn balance UNCHANGED on every node) end-to-end. Result on 4-node Postgres devnet: PASS in 126.4s. Files: - testing/forks/rehearsal/lib/signing.ts (NEW): - generateHarnessKeypair() — fresh ed25519 keypair via Cryptography.newFromSeed(crypto.randomBytes(32)). Same primitive ucrypto.generateIdentity uses; derivation is bit-identical to a production node start. In-memory only, never persisted, devnet only. - signHarnessTx(kp, content, blockHeight) — runs the fork-aware serializeTransactionContent + sha256 + Cryptography.sign chain to produce {hash, signature} in the shape the validating node expects via manageExecution({extra: "confirmTx", data: tx}). - testing/forks/rehearsal/lib/devnetControl.ts: - stageGenesisWithFundedAccount(fixture, pubkey, balance) — clones a rehearsal fixture, appends [pubkey, balance] to its balances array, writes the result to data/genesis.json. Reuses the same one-time prod-backup stageGenesis() produces. - testing/forks/rehearsal/scenarios/10-burn-spend-rejection.ts (rewritten from placeholder): - Generates fresh harness keypair. - Injects funded entry into genesis-fork-low-gasFee.json balances. - Boots 4-node devnet, waits for fork crossing (height >= 6). - Verifies osDenomination.activated + gasFeeSeparation.applied_at_block converged. - Builds a "send" tx whose gcr_edits include the malicious remove-from-burn entry alongside legitimate sender-remove / recipient-add. - Signs with harness keypair via the fork-aware serializer. - POSTs to node-1 as a confirmTx bundle. - Sleeps 15s, asserts burn balance == "0" on every node + fork_state unchanged. - decimal_planning/REHEARSAL_RESULTS.md: Run 7 section appended with the full harness procedure + result. Why "burn balance unchanged" instead of "validator returned specific message": the rejection mechanism can fire either at confirm-time (validating node refuses to sign ValidityData) OR at apply-time (GCRBalanceRoutines.apply returns success:false). Both outcomes produce the same observable state across nodes. The consensus- meaningful invariant is balance preservation; the specific message ("Cannot deduct from burn address") is a diagnostic log, not part of the wire response. Unit suite covers the apply-layer guard message explicitly (tests/blockchain/GCRBalanceRoutines.test.ts, 8 cases). Test suite (unit): unchanged, 281/282 pass with the pre-existing snapshotWeightIntegrity fail. Typecheck clean except pre-existing L2PS breakage.

Fixed both; rehearsal cycle now ends 10/10 PASS in 1929s. Bug 1 — run-all.sh empty-array expansion under macOS bash 3.2: set -u + "${EMPTY_ARRAY[@]}" throws "unbound variable" on bash 3.2. The runner crashed on the first scenario before bun ever fired. Switched to the portable ${EXTRA_ARGS[@]+"${EXTRA_ARGS[@]}"} parameter expansion which only emits words when the array is non-empty. Bug 2 — rpcNodeCall wire shape (lib/nodeQueries.ts): The harness flattened extraParams alongside message (params: [{ message, ...extraParams }]). manageNodeCall unpacks content.data and forwards it to every handler; handlers expect data.address (or similar). The flattened shape left data === undefined, every parametric nodeCall returned "Error in nodeCall: TypeError: undefined is not an object". Pre-myc#86 the bug was invisible because cross-node assertions compared Set.size === 1 of all-null returns and passed trivially. myc#86 strictened the null-check and scenario 06 started failing on every run. Fix: wrap extras under data: params: [{ message, data: Object.keys(extraParams).length > 0 ? extraParams : {}, }] Parameter-free RPCs (getLastBlockNumber, getNetworkInfo, ...) are unaffected because their handlers never read data.

P1 — calculateCurrentGas.ts additional_fee ignored governance (line 81) additional_fee was hardcoded to 0 while the additionalFee key was wired into PHASE_1_GOVERNABLE_KEYS + safetyBounds + the SDK NetworkParameters shape. A passing governance proposal raising it would have been stored but invisible to the collection path — silent fee-leak surface. Fix: added additionalFee scalar to SharedState (default 0), loadNetworkParameters mirrors NetworkParameters.additionalFee onto the scalar, calculateFeeBreakdown reads from shared state. New unit test asserts governance-driven additionalFee actually surfaces in the breakdown. P1 — loadForkConfig.ts BURN_ADDRESS duplicate constant (line 46) loadForkConfig.ts and migrations/gasFeeSeparation.ts both declared their own "0x" + "0".repeat(64) literal, with a unit test guarding equality. If the test were skipped (or the pre-existing failure masked it) the two could drift — migration creates the burn account at one literal while the runtime guard reads from another, allowing burned coins to be re-circulated. Fix: new leaf module src/forks/burnAddress.ts owns the single source of truth. Both modules import from it and re-export under their previous names so call sites stay stable. Invariant is now compile-time. P2 — feeDistribution.ts zero-percent init window (line 258) loadForkConfigFromGenesis primes feeDistribution with percentages = 0 to keep the structure non-null before loadNetworkParameters folds governance values. A post-fork tx processed in that window would route 100% of fees to treasury invisibly because all burn/rpc shares would be 0. Fix: requireFeeDistribution now refuses to emit edits when all seven percentage fields are zero, with a clear log line. The caller (applyGasFeeSeparation) surfaces the rejection through the standard ValidityData failure path. P2 — gasFeeSeparation.ts sqlite ON CONFLICT portability (line 326) ON CONFLICT (col) DO UPDATE SET … EXCLUDED.* requires sqlite ≥ 3.24.0. Documented as a portability note in-code; verified Bun's bundled sqlite is 3.44.2 (well above floor). The osDenomination migration already uses the same syntax, so the floor is implicit in the rehearsal stack; the doc is for future image downgrades. Test suite: 282/283 pass (1 pre-existing unrelated fail). Unit suites for fee-distribution, calculateFeeBreakdown, and applyGasFeeSeparation all green with the updated semantics.

Rehearsal scenarios that require source tweaks (e.g., seed balances, test migration logic) will need rebuild time. - ---- - -### Q2: How does 4-node startup order work? Do all nodes sync genesis simultaneously? - -**Answer**: Staggered by design. Node-1 boots first; others wait 20s before joining. - -**Details**: -- **start-staggered.sh** (`/Users/tcsenpai/kynesys/node/testing/devnet/start-staggered.sh`): - - Lines 8-14: Postgres + tlsnotary start first, wait for health check - - Lines 16-19: Node-1 starts alone; script sleeps 20 seconds - - Lines 34-35: Nodes 2-4 start together after node-1 has initialized genesis - -- **docker-compose.yml** lines 88-89 (`/Users/tcsenpai/kynesys/node/testing/devnet/docker-compose.yml:79-89`): - - Node-2 **depends_on** `node-1` (condition: service_started, not healthy) - - Node-3 and Node-4 also depend_on node-1 - - Dependency is on service start signal only, not health - -**Why**: Node-1 initializes the genesis block from `data/genesis.json` in the database. Lines 51-67 of `findGenesisBlock.ts` load fork config **before** the genesis-already-present early return, so node-1 must seed the DB first. Nodes 2-4 then sync from node-1. - -**Implication for rehearsal**: -- All 4 nodes do **NOT** boot simultaneously. They reach the same fork height eventually, but node-1 leads by ~20 seconds. -- This is acceptable for "all 4 cross fork height" scenarios provided the rehearsal allows for consensus timeout (CONSENSUS_TIME env var, default 10s per line 61). -- Race condition potential: minimal because forks are configured at startup via genesis; not injected mid-block. - ---- - -### Q3: Where does the devnet genesis come from? Is it in `testing/devnet/` or repo root? - -**Answer**: Genesis is loaded from **repo root `data/genesis.json`**, not devnet-specific copy. - -**Details**: -- **findGenesisBlock.ts** lines 51-59, 76-86 (`/Users/tcsenpai/kynesys/node/src/libs/blockchain/routines/findGenesisBlock.ts`): - - Hardcoded path: `data/genesis.json` - - Loaded once at startup before early return - - No devnet override path - -- **Dockerfile** line 27 (`/Users/tcsenpai/kynesys/node/testing/devnet/Dockerfile:27`): - - `COPY . .` includes `data/genesis.json` in image - -- **Current genesis.json** (`/Users/tcsenpai/kynesys/node/data/genesis.json`, lines 1-45): - - No `forks` field present - - Only `properties`, `mutables`, `balances`, `timestamp`, `status` - - This means `loadForkConfigFromGenesis` (loadForkConfig.ts:21-46) finds no forks and defaults all to `activationHeight: null` (inactive) - -**Implication for rehearsal**: Genesis is baked into the image. To change fork activation heights, either: -1. Modify `/Users/tcsenpai/kynesys/node/data/genesis.json` before building, rebuild image -2. Or implement dynamic override (see Q4) - ---- - -## B. Genesis Configurability for the Rehearsal - -### Q4: Can we modify genesis fork settings without rebuilding? - -**Answer**: **Currently, no easy way.** Genesis is baked. Dynamic configuration requires an adapter. - -**Details**: -- **loadForkConfigFromGenesis** (`loadForkConfig.ts:21-46`) parses the `forks` object from `genesisData` at lines 23-45 -- Fork config is read **once** at node startup in `findGenesisBlock()` (line 59 of findGenesisBlock.ts) -- No re-read or reload mechanism during runtime - -**Current options to add fork config without rebuild**: - -1. **Mount genesis as a volume** (minimal change): - - Add to docker-compose.yml node services: - ```yaml - volumes: - - ./data/genesis.json:/app/data/genesis.json:ro - ``` - - Problem: Requires separate `testing/devnet/data/` directory with rehearsal-specific genesis - - Advantage: No rebuild needed; change genesis, restart containers - -2. **Environment variable for activationHeight** (bigger change): - - Add env var override in `loadForkConfigFromGenesis()` (loadForkConfig.ts) - - E.g., `FORK_ODENOMINATION_ACTIVATION_HEIGHT=100` → `activationHeight = 100` - - Would need code change + rebuild once, then can flip env var without rebuild - -3. **Hardcode a small rehearsal height** (quick hack): - - Modify `data/genesis.json` to include: - ```json - { - ...existing fields..., - "forks": { - "osDenomination": { - "activationHeight": 5 - } - } - } - ``` - - Then rebuild image once. After that, can restart containers. - -**Recommendation**: Option 1 (genesis volume mount) is cleanest for devnet. Add to docker-compose.yml, keep rehearsal genesis in `testing/devnet/genesis.json`. - ---- - -### Q5: Can we seed initial balances or stakes pre-startup? - -**Answer**: **No mechanism in devnet currently.** Unit tests seed via SQL; production has genesis.json balances. - -**Details**: -- **Genesis balances** (`data/genesis.json` lines 9-27): - - Hardcoded array of [address, balance_wei] tuples - - No devnet override - -- **Test seeding pattern** (integration.test.ts lines 110-144): - - Tests insert directly into tables via EntityManager - - Uses SQL: `INSERT INTO gcr_main (pubkey, balance) VALUES (?, ?)` - - But no pre-populate mechanism in production startup flow - -- **Validator stakes**: Also come from genesis (integration.test.ts lines 147-157 seed `validators` table) - -**Current gap**: Cap-policy scenario needs >9M DEM legacy GCR account.

Adding a 5th Node Mid-Rehearsal - -### Q6: Can docker-compose accept a 5th node without breaking existing 4? - -**Answer**: **Yes, trivial.** Peerlist is pre-loaded at startup; adding a 5th service requires peerlist mutation logic (see Q7). - -**Details**: -- **docker-compose.yml** structure (lines 38-197): - - 4 identical node services (node-1 through node-4) - - Each depends only on postgres, tlsnotary, and node-1 (for startup ordering) - - No tight coupling; new node-5 service can be added as: - ```yaml - node-5: - image: demos-devnet-node - depends_on: - postgres: { condition: service_healthy } - tlsnotary: { condition: service_started } - environment: - - PORT=53559 - - OMNI_PORT=53560 - - PG_DATABASE=node5_db - volumes: - - ./identities/node5.identity:/app/.demos_identity:ro - - ./demos_peerlist.json:/app/demos_peerlist.json:ro - ports: - - "53559:53559" - ``` - - Postgres init must add `CREATE DATABASE node5_db;` (postgres-init/init-databases.sql line 1-12) - -**Implication**: Technically simple, but peerlist is read at startup. - ---- - -### Q7: Is the peerlist file mutable mid-run?

This was on our backlog from Session 4. -4. **Round-trip hash equality** holds for 5 fixture variants (OS-string, legacy DEM-number, bigint-normalized, non-canonical-OS, pre-fork).

Workaround: tests route via `handlerRegistry` instead of importing `forkHandlers` directly. Pre-existing in the codebase (governanceHandlers / peerHandlers do the same import pattern). Clean fix would be `import type { NodeCall }` in `Peer.ts`.

Per SPEC option (a) dual-format SDK design: -- SDK ships both serializers (DEM-number for pre-fork nodes, OS-string for post-fork) -- SDK calls `getNetworkInfo` to detect node fork status, caches per `Demos` instance -- Pre-fork transfer rejects sub-DEM precision with hard error (no silent value loss) -- Collapses IDEA.md phases 1–7 into one shippable SDK release -- Adds gcr_edits[] amount migration (the flag from Session 9) - -P4 is in the SDK repo (`/Users/tcsenpai/kynesys/sdks/`). When it ships → user publishes v3.0.0-rc.1 with `--tag rc` → P5 (node bumps SDK pin to RC, sets testnet fork height) → P6 (sustained testnet) → P7 (final v3.0.0) → P8 (production fork). - -## Session 11 (2026-05-06, P3b complete) - -### State -- Stabilisation/staking PR merged into `decimals` (merge commit `4b099c5d`). -- P3a regression confirmed intact post-merge (31/31 tests still pass). -- Re-investigation report: `decimal_planning/audit_node_post_staking.md`. Headline: `Validators.stake` was renamed to `Validators.staked_amount` (text/bigint-as-string), DEM-denominated, written via `GCRValidatorStakeRoutines.apply()`. Migration must include this column. -- User decisions locked: - - **Q1** — Cap policy for legacy GCR overflow (set to 90% of `Number.MAX_SAFE_INTEGER`, log every cap, record `cappedCount` and `totalValueLostOs` in fork_state audit row) - - **Q2** — Migration runs **inside** the same TypeORM transaction as block save (atomic) - - **Q3** — `NetworkUpgradeVote.weight` immutable at snapshot, no tally-time adjustment -- P3b shipped in 4 commits (`c6b91c57`..`fff62854`): - - `feat(forks): add ForkState entity and TypeORM migration` - - `feat(forks): implement osDenomination state migration with cap policy` - - `feat(forks): hook fork migrations into Chain.insertBlock` - - `test(forks): osDenomination migration tests` -- Plus `e497cd5a docs(decimal_planning): add post-staking-merge investigation report`. - -### What's verified -- Cap value: `LEGACY_NUMBER_CAP = 8_106_479_329_266_892n` OS = `BigInt(Math.floor(Number.MAX_SAFE_INTEGER * 0.9))` -- 11/11 new migration tests pass, including: cap behavior (test 4), idempotency throw (7), outer-transaction rollback (8), atomicity on poison row (9), empty-chain edge case (1) -- 42/42 in `testing/forks/` overall (31 baseline + 11 new) -- Lint clean, typecheck baseline (11) preserved, no new errors -- Bit-identical regression PASS: production behavior unchanged when `activationHeight: null` -- Hook integration: atomic per Q2, no invasive refactor needed (existing `dataSource.transaction(em => ...)` block in `chainBlocks.insertBlock:218` was already in place) -- Migration runs **before** block transactions execute, so the triggering block's txs see post-fork (OS) balances - -### Test infrastructure note -P3b introduced `placeholder()` helper for portable raw queries (Postgres `$N` / SQLite `?`). Tests use SQLite in-memory; production uses Postgres. `ON CONFLICT` syntax is identical across both for fork_state UPSERT. - -### Closed Mycelium tasks -- #22 (P3) — close on next session start (P3a + P3b done; P3c and P3d still ahead in current session) - -Wait — P3 is task #22 covering all of P3a/b/c/d.

A staking PR is in approval that adds the write side. Migrating consensus-relevant state without seeing the final staking design risks corrupting validator sets at fork. - -User decision: pause here, wait for staking PR to merge into `stabilisation`, pull it, then revisit P3b investigation with complete picture. - -### State preserved -- 12 commits on `decimals` branch (P-1 + P0/P1 + P2 + P3a). All independently valid. -- 31/31 tests pass in `testing/forks/`. -- Lint clean, typecheck baseline (11 errors) preserved. -- `decimal_planning/PAUSED.md` written with full resume protocol. -- Mycelium: P-1, P0, P1, P2 closed. P3a closed (need to do). P3b open (the blocker). - -### Cleanup -- Discarded 45 files of formatter-noise unstaged edits from the P3b investigation Senior. Workspace clean. -- No P3b code was written — only investigation. Nothing to revert in commits. - -### Resume target -When staking PR lands: read PAUSED.md → pull staking → re-run P3a regression → re-investigate `Validators.stake` with staking PR design → resume P3b implementation. - -## Session 9 (2026-05-01, P3a complete) - -### State -- P3a done in 2 commits (`2b2d2ece`, `974b361b`). Branch is now 12 commits ahead of main. -- 13 new tests, total 31/31 in `testing/forks/`. Bit-identical regression for default (inactive) config still passes. -- Validators: P-1's `BigInt()` coercions already handle both number and string inputs. No P3a-specific validator work needed. -- BlockContent: verified to have no amount/fee fields. Post-fork block branch is a deliberate no-op (kept structurally for future forks). -- Canonical wire key order observed: `type, from, to, amount, data, nonce, timestamp, transaction_fee, from_ed25519_address, gcr_edits`. Insertion-order preservation via `{ ...content }` spread is sufficient (no explicit canonicalization needed; matches pre-fork behavior). - -### Open finding for P4 -`tx.content.gcr_edits[]` entries carry per-entry `amount: number` (DEM) today. Senior flagged this for review. Resolution: -- The "mixed v2 SDK + post-fork node" scenario is explicitly rejected per SPEC option (a) — SDK v3 detects fork status and refuses to send v2-format to post-fork nodes -- SDK v3 (P4) must produce gcr_edits with OS-string amounts as part of its type migration -- **Action item for P4 brief**: explicitly list gcr_edits as a migration target — not just top-level amount/fees -- **No action in P3a**: gcr_edits format is the SDK's responsibility, not the node serializer's - -### Next: P3b (state migration script) -Most consensus-sensitive piece. Multiplies every account balance by 10^9 at fork activation. Two backends to handle (Session 5 finding): -1. GCRv2 `gcr_main.balance: bigint` — direct multiplication -2. Legacy `GlobalChangeRegistry` JSONB column (number) — must widen + multiply, may need MAX_SAFE_INTEGER pre-check -Sum invariant: `Σ(post) = Σ(pre) × 10^9`. Idempotency flag in DB. - -## Session 8 (2026-05-01, P2 complete, P3 planning) - -### State -- P2 landed in 6 logical commits (`2891f745`..`a5e28183`). Branch `decimals` is now 10 commits ahead of main. -- 18 new tests in `testing/forks/`. Bit-identical regression confirmed at heights 0, 1, 1M, 999_999_999, with fork forcibly active too (placeholder branch returns identical bytes — P3 will fill it in). -- Audit corrections (recorded so we don't trust the audit blindly in P3): - - 7 tx hash sites (not 6): audit missed `signalingServer.ts:664` - - audit's `transaction.ts:192` was a debug log; actual sites are 91, 108, 269 - - Senior's confirmed list of 7+2 sites is canonical for P3 -- `findGenesisBlock` loads fork config before the early-return so existing nodes pick up new fork heights on restart, not just on first init. -- `Transaction.sign/hash/isCoherent` got optional `blockHeight` param defaulted to `getSharedState.lastBlockNumber ?? 0`. Callers can override when they know the owning block (P3 will). - -### P3 split decision -P3 is too large for one Senior dispatch. Splitting into 4 sub-phases: -- **P3a**: Dual serializer (the post-fork branch becomes real) + dual validators (amount/balance/fee BigInt-typed post-fork) -- **P3b**: State migration script (×10^9, sum invariant, dual-backend: GCRv2 bigint AND legacy GlobalChangeRegistry JSONB number) + auto-trigger hook on first sight of block ≥ activationHeight -- **P3c**: `getNetworkInfo` RPC for SDK fork detection -- **P3d**: Integration tests in `testing/`: snapshot replay, hash distinctness pre/post fork, fork-boundary edge cases - -Each sub-phase is its own Senior dispatch, separate commits, independently reviewable. Mycelium task #22 covers all four; will close when all done. - -### Closed Mycelium tasks -- #21 (P2) closed - -## Session 7 (2026-05-01, P0+P1 complete, P2 starting) - -### State -- SDK v2.12.0 published with denomination utilities. Node bumped from `^2.11.4` → `2.12.0` (exact pin to avoid caret drift across major bumps later). -- Node P1 commit: `f140a0c7 chore(deps): bump demosdk to 2.12.0`. **Zero conversion sites needed replacement** — exhaustive grep confirmed audit_node.md:129's claim that node has no DEM↔OS math today. Conversion is **introduced** in P3. -- Typecheck baseline now 11 errors (down from 32 post-P-1; some dropped naturally from the SDK bump's cleaner types). -- SDK import idiom confirmed: `import { denomination } from "@kynesyslabs/demosdk"` then `denomination.demToOs(x)`. Namespace-only, no flat re-export. - -### Closed Mycelium tasks -- #19 (P0) closed -- #20 (P1) closed - -### Next: P2 — node hard-fork machinery -Per `forking_feasibility.md`: M-sized, ~2 person-days.

Behavior must be bit-identical post-P2. - -## Session 6 (2026-05-01, P0 publish gate) - -### State -- P0 SDK changes (`f951fbc`) merged with upstream (`af1c7c9`) on SDK main branch. -- Verified merge didn't touch P4 hot spots (getAddressInfo, transfer, TxFee, amount, balance semantics unchanged). -- Build clean post-merge, all 11 denomination tests pass. -- User published v2.12.0 to npm. - -## Session 5 (2026-05-01, P-1 complete) - -### Status -- All three P-1 commits landed: - - `438ade1f` fix(consensus): use BigInt instead of parseInt in subOperations - - `c343d426` fix(model): widen Transactions fee columns from integer to bigint - - `cf798bad` fix(gcr): coerce editOperation.amount to BigInt at routine boundary -- Lint clean on touched files. Repo-wide TS error count bit-identical to baseline (32 errors, all pre-existing). -- TypeORM migration `WidenFeeColumnsToBigint1714521600000` created at `src/migrations/`. - -### Important finding flagged for P3 -Senior discovered that `getGCRNativeBalance` was reading `details.content.balance` from the **legacy** `GlobalChangeRegistry` JSONB column typed as `number` — not the GCRv2 `GCRMain.balance: bigint` the audit assumed. This means **two storage backends** must be migrated in P3: -1. GCRv2 `gcr_main.balance` — already bigint, just multiply by 10^9 -2. Legacy GlobalChangeRegistry JSONB — currently `number`, must be widened AND multiplied -P-1 added a `MAX_SAFE_INTEGER` guard in `setGCRNativeBalance` so the legacy path fails loudly instead of silently truncating, but the dual-backend migration is now an explicit P3 requirement. - -### Pre-existing issues out of scope (deferred) -- `subOperations.ts:62` — `transaction.amount = 0` against `bigint` entity field (broken before P-1). -- `chainTransactions.ts`/`chainBlocks.ts` — `Repository.save(RawTransaction)` typing mismatch where SDK `RawTransaction` types fees/amounts as `number` but entity is `bigint`. Resolves naturally in P4 (SDK type migration). -- `getAddressInfo` zero-balance FIXME — deferred to P3 per Session 4 decision. - -### Closed Mycelium task -- #18 (P-1) → close on next session start: `myc task close 18` - -## Session 4 (2026-05-01, P-1 start) - -### Scope adjustment to P-1 -- Original P-1 had 4 sub-tasks. The 4th — fixing `getAddressInfo` zero-balance FIXME — turned out to be **SDK-side only** (the FIXME lives in `../sdks/`, not in the node). -- Properly fixing it requires the node to emit `balance: string` instead of `balance: number/bigint`, which is a wire-format change. That belongs in P3 (dual-rule serialization), not in P-1's "no migration logic" phase. -- **Decision**: dropping FIXME fix from P-1; will be handled naturally by P3. -- P-1 now has 3 sub-tasks: - 1. `parseInt(amount)` → `BigInt(amount)` in `src/libs/blockchain/routines/subOperations.ts` (lines 83, 96, 147, 163, 171) - 2. Widen 32-bit fee columns in `src/model/entities/Transactions.ts` (lines 52-59) — `networkFee`, `rpcFee`, `additionalFee` from `integer/number` to `bigint/bigint`. Generate TypeORM migration. - 3. Type assertions in `src/libs/blockchain/gcr/gcr_routines/GCRBalanceRoutines.ts` (lines 26, 65) — coerce `editOperation.amount` to BigInt at the boundary. -- File `src/model/entities/Transactions.ts:43` already has `amount: bigint` ✓ — only fees need widening. -- `subOperations.ts:96` does `parseInt(...)` then `isNaN(...)` checks — must replace with `BigInt(...)` in try/catch since BigInt throws on bad input. - -## Session 3 (2026-05-01, continued) - -### State -- User chose **option (a)** for SDK-vs-pre-fork compatibility: dual-format SDK that detects fork status and serializes accordingly. -- SPEC.md updated with option (a) details: - - SDK ships both serializers (DEM-number for pre-fork, OS-string for post-fork) - - Node adds `getNetworkInfo` (or similar) RPC in **P3** so SDK has something to query — moved from P4 to P3 to honor the strong-reading constraint - - SDK caches fork status per `Demos` instance, refreshes when nearing activation height - - Pre-fork serialization rejects sub-DEM precision with a hard error -- Mycelium epic #3 created with 9 tasks (P-1 through P8), full dependency chain wired: - - Task 18 (P-1) is the only currently unblocked task - - All others blocked in sequence per SPEC.md §2 - -### Resume protocol (post-compaction) -1.

Scripts to be written in the next phase. - ---- - -## 0. Why this plan exists - -The fork mechanism is unit-tested against SQLite in-memory: 52/52 tests pass in `testing/forks/`. That confirms the **logic** is sound. It does **not** confirm: - -- The migration runs correctly on PostgreSQL 16 (text-based numeric arithmetic, JSONB casting, transactional rollback semantics). -- Real peer sync — gossip, block relay, mempool drain — handles the fork boundary. -- The `getNetworkInfo` RPC returns sane values across 4 independent nodes that may briefly disagree on `currentHeight`. -- A node that joins **after** the fork can replay history and end up converged. -- `BlockContent`'s genesis-hash invariance under added `forks` field actually holds in practice. -- The cap policy fires loud (and stays loud) when migration overflows the legacy backend. - -Each scenario below maps to one of those gaps. Scripts will be `bash` driving `docker compose` + `bun` for SDK calls, `psql` for DB introspection, plus `curl` for RPC. No code attaches to the running node process. - ---- - -## 1. Conventions used in this plan - -- **Genesis variants**: we maintain 3 genesis files under `testing/devnet/scenarios/genesis/`: - - `genesis-pre-fork.json` — current production layout, no `forks` field. - - `genesis-fork-low.json` — `forks.osDenomination.activationHeight: 5` (fast cross-over for happy path). - - `genesis-fork-overflow.json` — same as `-low.json` but with one balance entry seeded above the legacy cap (>9M DEM equivalent in JSONB legacy GCR). -- **Binary variants**: two image tags built from the docker-compose context: - - `demos-devnet-node:pre-fork` — built from a commit at `decimals` branch tip **before** P3 fork machinery (or the equivalent feature-flag-disabled build). Used only in scenario 2 (desync) and 4 (genesis-hash invariance). - - `demos-devnet-node:post-fork` — built from current `decimals` HEAD with all P3 + P5 changes. Default image for everything else. -- **Observation primitives**: - - `psql` queries against `node{1..5}_db` (a fifth db is added in scenarios 3 and 4 by extending `postgres-init/init-databases.sql`). - - RPC: `curl http://localhost:5355{1..5}/rpc/...` — at minimum `getLastBlock`, `getNetworkInfo`, `getAddressInfo`. - - Logs: `docker compose logs node-N --since 1m` filtered with `grep -E '(fork|migration|cap|ABORT|ERROR)'`. -- **Repeatability**: every scenario starts with `docker compose down -v` (full state wipe) and ends with the same. We do **not** chain state across scenarios. -- **Driver script convention**: `testing/devnet/scenarios/-/run.sh` is the entry point, plus a sibling `expect.sh` that asserts pass/fail, returning non-zero on failure. A top-level `testing/devnet/scenarios/run-all.sh` runs them in the documented order and writes a JUnit-style summary. - ---- - -## 2. Scenarios - -### Scenario 1 — All-validators-cross-fork (the base case) - -**Goal**: Prove that 4 fully-coordinated nodes can cross the fork, run the migration, and converge with matching post-fork balances. This is the minimum-viable success. - -**Setup**: -- All 4 nodes use `demos-devnet-node:post-fork` image. -- All 4 nodes use `genesis-fork-low.json` (activation height = 5). -- Pre-seed each node's `node{1..4}_db` (via SQL fixture loaded after first startup, or via genesis `balances` if simpler) with the same 5-account distribution: 4 validator stakes (1000 DEM each) + 6 user balances (mixed: 100, 50, 0.5, 9_000_000, 0.000001, 1). -- Postgres clean. - -**Action**: -1. `docker compose up -d` with `genesis-fork-low.json`. -2. Wait until all nodes report `getLastBlock.number >= 6` (one block past activation). -3. Snapshot every DB's `gcr_main`, `validators.staked_amount`, `global_change_registry.details`, `fork_state` table. - -**Observation points**: -- `fork_state` row exists on all 4 nodes with `fork_name='osDenomination'`, `applied=true`, `migration_block_number=5`, identical `cappedCount` and `totalValueLostOs` (both should be 0 here). -- `getNetworkInfo` on each node returns `osDenomination.activated=true`. -- Block hash for block N (=5) matches across all 4 nodes (compare via RPC `getBlock?height=5`). -- Sum invariant: `Σ(post_balances) == Σ(pre_balances) × 10^9` per node; same sum across all 4 nodes. - -**Success criteria**: -- All 4 `fork_state` rows are bit-identical (excluding `completed_at` timestamp). -- Block 5 hash identical across all 4 nodes. -- Sum invariant holds with zero cap losses. -- All 4 nodes still produce blocks past height 5 for at least 60 seconds. -- No error/panic strings in logs. - -**Failure mode caught**: Postgres-specific bugs in the migration SQL (e.g., text-cast arithmetic differing from SQLite, JSONB path expression differences, transactional isolation issues), peer divergence on the fork boundary. - -**Estimated runtime**: ~3 min (build cached). - ---- - -### Scenario 2 — Validator desync recovery - -**Goal**: Prove that an out-of-date validator can catch up by wiping its chain.db and re-syncing from genesis after the fork has already happened. - -**Setup**: -- Nodes 1–3 on `demos-devnet-node:post-fork` + `genesis-fork-low.json`. -- Node 4 on `demos-devnet-node:pre-fork` + `genesis-pre-fork.json` (no `forks` field). Same identities/peerlist. -- Same pre-seeded balance distribution as scenario 1. - -**Action**: -1. `docker compose up -d`. -2. Wait until nodes 1–3 cross height 5 and migrate; node 4 stays stuck (rejects post-fork blocks because its serializer can't validate them, or hard-errors because it doesn't know about `forks`). -3. Confirm node 4 is desynced: its `getLastBlock.number < 5` while peers are >5, or it's logging signature/hash failures. -4. `docker compose stop node-4`. Drop node 4's database: `psql ... -c "DROP DATABASE node4_db; CREATE DATABASE node4_db OWNER demosuser;"`. Replace node 4's image tag with `:post-fork` and its genesis with `genesis-fork-low.json` (compose override file). -5. `docker compose up -d node-4`. -6. Wait for node 4 to sync to current height. - -**Observation points**: -- Logs on node 4 during step 3: should contain explicit hash mismatch or "unknown fork" error. -- Postgres `node4_db.fork_state` table after step 6: `applied=true`. -- Sum invariant on node 4 matches nodes 1–3. -- Block hash at height 5 on node 4 matches the other 3. - -**Success criteria**: -- Node 4 fails LOUDLY in step 3 (we want a clear error in logs, not a silent stall). -- After wipe + restart, node 4 catches up within 60s of consensus time. -- All 4 nodes converge: identical block hashes for height 5, 6, …, current. Identical `fork_state` rows. - -**Failure mode caught**: Re-sync after a wipe doesn't replay the migration on the catching-up node; or the migration runs but produces a different result because the catching-up node has a slightly different mempool snapshot. Also: regression in error-loudness — silent failure is worse than loud. - -**Estimated runtime**: ~6 min (two upbringings + sync wait). - ---- - -### Scenario 3 — Fresh node post-fork (HIGHEST STAKES) - -**Goal**: Prove that a node that joins **after** the fork has already happened can sync the entire chain from genesis, including pre-fork blocks, and end up converged with the others. This validates the static-trace claim from the Senior investigation in Session 14 — that the migration hook fires correctly during replay. - -**Setup**: -- Step 0 (preparation): extend `postgres-init/init-databases.sql` to also create `node5_db`. Extend compose with a `node-5` service that depends on node-1..4 being healthy. Give it port `53555` for RPC. -- Nodes 1–4 on `:post-fork` + `genesis-fork-low.json`. Same pre-seeded balances as scenario 1. -- Node 5 NOT started yet. - -**Action**: -1. `docker compose up -d node-1 node-2 node-3 node-4`. -2. Wait for all 4 to cross height 5 and run the migration (same as scenario 1). -3. Let the network advance to height ~50 (post-fork by a comfortable margin), so node 5's sync has to replay both pre-fork and post-fork blocks. -4. `docker compose up -d node-5` (image `:post-fork`, genesis `genesis-fork-low.json`, empty `node5_db`). -5. Wait for node 5 to sync to current height. - -**Observation points**: -- Node 5 log line "applying fork migration osDenomination at block 5" must appear (or whatever the equivalent log statement is). -- `fork_state` on node 5 after sync: `applied=true`, `migration_block_number=5`. -- Block hashes on node 5 for heights 1..5 (pre-fork) and 5..current (post-fork) match the other nodes exactly. -- Sum invariant on node 5: matches the other 4. -- `getAddressInfo` on node 5 for any seeded account returns identical balance to node 1. - -**Success criteria**: -- Node 5 reaches current height within a reasonable timeout (e.g. 3 minutes). -- All hashes match. Sum invariant matches. No log errors or peer-rejection warnings. -- `fork_state` recorded with the same effective metadata (cap counts, etc.) as the original fork on nodes 1–4. - -**Failure mode caught**: The static-trace claim is wrong. The migration hook fires during proposing/inserting NEW blocks but does not fire during historical replay, leaving node 5 with pre-fork balances while it tries to validate post-fork blocks. This is the highest-likelihood real bug. - -**Estimated runtime**: ~7 min (network warmup + late-joiner sync). - ---- - -### Scenario 4 — Genesis-hash invariance - -**Goal**: Prove that adding a `forks` field to `genesis.json` does NOT change the computed genesis block hash. This validates the static-trace claim that `BlockContent` does not include `forks` and that an existing chain.db built before the field was added will still accept the new genesis. - -**Setup**: -- Step 1: Bring up node 1 on `:pre-fork` image with `genesis-pre-fork.json` (no `forks` field). Let it produce blocks for ~30s. -- Step 2: `docker compose stop node-1`. -- Step 3: Swap genesis to `genesis-fork-low.json` (adds `forks` field, NO other changes). Swap image to `:post-fork`. -- Step 4: `docker compose up -d node-1` against the **same** `node1_db` (no DB wipe). - -**Observation points**: -- Node 1's startup logs in step 4 must NOT contain a "genesis hash mismatch" error. -- The genesis row in `node1_db.blocks` table has the same hash as before (verify by capturing the hash in step 1 and comparing). -- Node 1 reaches its previous tip and continues producing blocks. - -**Success criteria**: -- Node 1 starts cleanly. No mismatch logs. -- Genesis hash identical pre/post genesis-file edit. -- Chain continues from existing tip (no replay-from-zero). - -**Failure mode caught**: `BlockContent` actually does include `forks` (or some other field that touches the hash). If this scenario fails, the entire fork-activation strategy needs to be redesigned because every existing node will reject the new genesis. - -**Estimated runtime**: ~2 min. - ---- - -### Scenario 5 — Cap policy fires loud - -**Goal**: Prove that when the legacy GCR overflows the cap, the migration aborts loudly, the block doesn't apply, and `fork_state` records exact forensic data. Then prove that a retry path (either fix the seed or accept the cap) works. - -**Setup**: -- All 4 nodes on `:post-fork` image. -- Genesis: `genesis-fork-overflow.json` — same as `-low.json` but seeds the legacy GCR JSONB column with one account holding `9_500_000` DEM (> the 9M cap derived from `Number.MAX_SAFE_INTEGER * 0.9 / 10^9`). -- `activationHeight = 5`. - -**Action — Phase A (loud failure)**: -1. `docker compose up -d`. -2. Wait until nodes attempt to insert block 5. -3. Observe migration aborts on all 4 nodes. - -**Action — Phase B (retry with cap accepted)**: -4. `docker compose down -v`. -5. Modify the genesis migration policy to accept the cap (or modify the seed to not overflow — pick whichever the policy says is the operator's intent). -6. `docker compose up -d`. -7. Wait for cross-fork. - -**Observation points (Phase A)**: -- All 4 nodes log a clearly-formatted CAP / ABORT message identifying the offending account and the cap value. -- Block 5 is NOT in `node{1..4}_db.blocks` table (only blocks 0..4 exist). -- All 4 nodes are stuck at height 4. `fork_state.applied = false` (or row doesn't exist). -- `getNetworkInfo.osDenomination.activated = false` because we never crossed the height successfully. - -**Observation points (Phase B)**: -- Cap is now logged but accepted. `fork_state.cappedCount > 0`, `totalValueLostOs > 0`, both identical across nodes. -- Migration applied. Block 5 in DB. Network resumes. - -**Success criteria**: -- Phase A: nodes halt loudly, fork_state untouched, sum invariant on the existing rows still holds (because nothing was migrated). -- Phase B: cap forensics are bit-identical across all 4 nodes, network advances. - -**Failure mode caught**: Migration silently truncates or silently succeeds when overflowing. If the cap policy fires-quiet, value is destroyed without operator awareness — that's the worst possible outcome for this migration. We must verify the **fail-loud** contract empirically on real Postgres, not just SQLite. - -**Estimated runtime**: ~5 min (two cycles). - ---- - -### Scenario 6 — Mid-flight transactions across the boundary - -**Goal**: Prove that transactions submitted by SDK v3 clients in the immediate vicinity of the fork height land correctly. Specifically: a tx submitted while the network is at height N-1 ends up in a post-fork block; the SDK pre-flight `getNetworkInfo` returns the correct `activated` state at submission time; the tx is accepted. - -**Setup**: -- All 4 nodes on `:post-fork` image, `genesis-fork-low.json` with `activationHeight = 10` (slightly higher to give us room to send the tx before fork). -- Pre-seeded balances as in scenario 1. - -**Action**: -1. `docker compose up -d`. -2. While network is at height 8 or 9 (poll via `getLastBlock`), use SDK v3 (or a curl-driven RPC) to submit one transfer of 1 DEM (= 10^9 OS) from sender to recipient. -3. Wait for the tx to be confirmed. -4. Inspect which block it landed in. - -**Observation points**: -- The tx's `content` shape on the wire (capture via RPC `getMempool` immediately after submission, before it confirms): `amount` field as DEM-number if SDK detected pre-fork, OS-string if post-fork. -- Block height at which the tx is included: should be either the last pre-fork block (9) or the first post-fork block (10). -- If included at 10: the migration ran first, so the sender's balance available for spending is `(pre × 10^9) - amountSpent`. Verify with `getAddressInfo`. -- Recipient balance after confirmation matches expected post-fork value. -- All 4 nodes agree on the resulting balances (sum-check). - -**Success criteria**: -- Tx accepted, included in a block, balances correct on all 4 nodes. -- No "signature invalid" or "format mismatch" errors in logs near the boundary. - -**Failure mode caught**: Mempool drain edge cases — a tx serialized in pre-fork format while the validator picking it up is post-fork (or vice versa). Hash/signature mismatch races at the boundary. - -**Estimated runtime**: ~3 min. - ---- - -### Scenario 7 — Sum invariant audit - -**Goal**: Independently verify the sum-invariant claim on real Postgres by computing pre- and post-fork totals across all three balance backends (`gcr_main.balance`, `validators.staked_amount`, legacy `global_change_registry.details.content.balance`) and asserting `Σ(post) = Σ(pre) × 10^9 - Σ(capLosses)`. - -**Setup**: -- All 4 nodes on `:post-fork` + `genesis-fork-low.json`. Activation height = 10. -- Pre-seeded: a non-trivial distribution including some legacy-backend accounts (under the cap), some GCRv2 accounts, and some validator stakes. - -**Action**: -1. `docker compose up -d`. -2. While network is below height 10, run the snapshot script: dumps `Σ` of each backend on each node into `pre.json`. -3. Wait for height 10+ on all 4. -4. Run snapshot script again: `post.json`. -5. Run the assertion script: for each node, `post == pre × 10^9 - capLosses` (capLosses retrieved from `fork_state`). - -**Observation points**: -- Pre and post sums per backend per node. -- Cap losses recorded in `fork_state.totalValueLostOs`. -- Cross-node consistency: identical pre, identical post. - -**Success criteria**: -- Invariant holds exactly on all 4 nodes. -- All 4 nodes' pre-sums match each other (consistency before the fork). -- All 4 nodes' post-sums match each other (consistency after). - -**Failure mode caught**: Migration multiplies one backend but not another (e.g., misses validator stakes, or double-multiplies legacy-GCR via JSONB path bug). The unit tests assert this in SQLite; this scenario asserts it in Postgres with realistic seeded distribution. - -**Estimated runtime**: ~3 min. - ---- - -### Scenario 8 — Re-sync after fork without DB wipe - -**Goal**: A node that had already synced through the fork crashes and restarts. Verify it does NOT re-run the migration (idempotency), picks up correctly, and continues producing/validating blocks. - -**Setup**: -- All 4 nodes on `:post-fork` + `genesis-fork-low.json` (activation 5). Pre-seeded balances. - -**Action**: -1. `docker compose up -d`. -2. Wait for cross-fork on all 4. -3. Snapshot `fork_state` and a sample of `gcr_main` from node 4. -4. `docker kill demos-devnet-node-4` (ungraceful shutdown). -5. `docker compose start node-4`. -6. After node 4 reconnects, snapshot `fork_state` and the same `gcr_main` sample again. - -**Observation points**: -- `fork_state.applied = true` both before kill and after restart, with identical `completed_at` timestamp (proving migration was NOT re-run — it would update the timestamp if it had). -- Sample balances unchanged (proving they weren't multiplied by 10^9 a second time). -- Node 4 catches up to peers within consensus_time × small N. -- No "applying fork migration" log line during restart. - -**Success criteria**: -- `fork_state` row identical pre/post crash. -- Sample balances identical pre/post crash. -- No re-migration log line. - -**Failure mode caught**: Idempotency gate is broken — migration runs twice, balances become DEM × 10^18, network state diverges fatally. This is the doomsday bug. Catching it here on devnet beats catching it on testnet. - -**Estimated runtime**: ~3 min. - ---- - -## 3.

Proposed run order - -Some scenarios depend on others passing first: - -1. **Scenario 4** — Genesis-hash invariance. **Must run first.** If this fails, every other scenario is wasted because the entire fork model is wrong. -2. **Scenario 1** — All-validators-cross-fork. The base case. If this fails, nothing else is reachable. -3. **Scenario 7** — Sum invariant audit. Builds confidence that the migration math is correct on Postgres, before stressing it. -4. **Scenario 8** — Idempotent restart. Cheap, catches the doomsday-bug class. -5. **Scenario 5** — Cap policy fires loud. Standalone, runs on its own genesis. -6. **Scenario 6** — Mid-flight transactions. Requires baseline migration to work. -7. **Scenario 2** — Validator desync recovery. Slowest, requires both image variants. -8. **Scenario 3** — Fresh node post-fork. **Highest stakes**, most expensive setup, runs last so any earlier failure short-circuits. - -`run-all.sh` should `exit 1` on the first failure, with explicit notice that subsequent scenarios were skipped. - ---- - -## 5. Risk register — what this rehearsal does NOT cover - -| Risk | Why it's not covered | Mitigation | -|---|---|---| -| Production-scale validator count | Devnet runs 4 nodes; production runs ~dozens. Convergence under heavy peer count not exercised. | P6 sustained testnet run (>10 nodes) gates production. | -| Production Postgres tuning | Devnet uses default `postgres:16-alpine`. Production may have different `work_mem`, replica configs, vacuum schedules. | Capture migration wall-clock on devnet as a floor; multiply by 10x and review against ops constraints. | -| Real-world balance distribution | Seeded fixtures are synthetic. Real chain has long-tail account distribution. | P5/P6: take a snapshot of testnet GCR, replay it through a migration dry-run before production fork. | -| Network partitions / Byzantine peers | Devnet network is an idealized Docker bridge. No latency, packet loss, or malicious peer simulation. | Out of scope for P5b. Captured under Risk Register P0 — accepted. | -| SDK v2 talking to post-fork node | Considered as scenario 9, see §6. | Skipped — covered by P4 SDK contract test. | -| Long-running stability past fork (>1 day) | Each scenario runs minutes, not days. Memory leaks, slow disk-fill, validator-set churn over time not observable. | P6 sustained testnet run. | -| TLSNotary integration during fork | tlsnotary is part of devnet but no scenario exercises a notarization across the boundary. | Out of scope; tlsnotary doesn't touch balances. Add to P6 if user requests. | -| Production identity rotation / key changes | Devnet uses static identities. | Out of scope. | -| Genesis with thousands of balance entries | Synthetic genesis is small. JSONB widening may behave differently at scale. | Capture migration timing per row count; extrapolate. Add to P6 dry-run if extrapolation is concerning. | - ---- - -## 6. Scenarios considered but cut - -- **SDK v2 talking to post-fork node** (originally on the spec): cut from this rehearsal because P4 already shipped a contract test in the SDK repo (Session 13, `wireFormat.spec.ts`) that covers the case at the SDK boundary. Re-running the same check at the devnet level adds no new signal. If the user disagrees, it slots in between scenarios 5 and 6 and adds ~3 min. -- **Mempool flush during reorg across fork**: cut because devnet doesn't easily reproduce reorgs without a custom Byzantine harness. Best handled in P6 testnet under real adversarial conditions. -- **Storage-program / IPFS fee migration end-to-end**: cut because storage-program writes go through the same `gcr_edits[]` path that scenario 6 exercises; running it twice on different programs adds no new code path coverage. - ---- - -## 7. Operational notes for the script-implementation phase - -- **Build caching**: the two image variants (`:pre-fork`, `:post-fork`) should be built once at the top of `run-all.sh` and tagged. Each scenario's `run.sh` does `docker compose down -v` but reuses the cached images. -- **Genesis swap**: avoid editing `data/genesis.json` in-place. Use a compose override file per scenario (`docker-compose.scenario-.yml`) that mounts the right `genesis-*.json` over the default. -- **Wait helpers**: provide a `scripts/wait-for-height.sh ` and `wait-for-fork-applied.sh ` so scenario scripts read clearly. -- **DB introspection**: provide `scripts/db-query.sh ` that wraps `docker exec demos-devnet-postgres psql -U demosuser -d node{N}_db -t -A -c ""`. -- **Pass/fail reporting**: each scenario writes `result.json` `{ "scenario": "...", "status": "pass"|"fail", "duration_s": N, "evidence": [...] }`. `run-all.sh` aggregates. -- **No flake tolerance**: any scenario that's flaky should be redesigned, not retried. Fork mechanics are deterministic; if the rehearsal isn't deterministic, we have a bug. - ---- - -## 8.

Read end-to-end before fork day. - ---- - -## 1. Overview - -This runbook covers the one-time activation of the `osDenomination` hard fork on testnet. The mechanism is a block-height-gated state migration that runs **inside** `Chain.insertBlock`'s atomic TypeORM transaction at `src/libs/blockchain/chainBlocks.ts:218`. At the first block where `block.number === activationHeight`, the migration multiplies every `gcr_main.balance`, every legacy `global_change_registry.details.content.balance`, and every `validators.staked_amount` by `10^9`, then writes a single row to `fork_state`. Idempotency is enforced by reading `fork_state.applied` before running. The hook also fires during historical replay, so fresh validators sync correctly without operator intervention (Run 5 Scenario 3 — confirmed on real Postgres + real peer sync). - -For design rationale, see `decimal_planning/SPEC.md` §1 and `decimal_planning/forking_feasibility.md` §3, §5, §8. - ---- - -## 2.

If seen, the SDK misdetected fork status; refresh the `Demos` instance. -- **`forks.osDenomination` stays in genesis forever.** Preserve the entry. Future forks add new entries; they do not replace this one. -- **`fork_state` row stays in the DB forever.** Audit data. Do not edit manually. - ---- - -## 8. Don't-do list - -- **Don't change `data/genesis.json` `balances` mid-run.** Genesis-hash invariance (Run 5 Scenario 4) covers the `forks` field only. Balance changes ARE inside `BlockContent` and will invalidate every existing `chain.db`. -- **Don't enable `DEMOS_DISABLE_FORK_MACHINERY` on testnet/production.** Rehearsal-only flag (`loadForkConfig.ts:42`). With it set, the migration hook never fires and the validator silently desyncs at `N`. -- **Don't skip the genesis update on any validator.** A validator without `forks.osDenomination.activationHeight` never crosses the fork; it hard-fails on every post-fork block from peers. -- **Don't activate at a height too close to current head.** §3 mandates ≥ 600 blocks lead time. -- **Don't roll back the binary post-fork.** The pre-fork binary cannot validate post-fork blocks. Rolling back guarantees desync. -- **Don't delete `fork_state` rows.** Idempotency depends on them. Removal causes the migration to re-run on restart, double-multiplying every balance — unrecoverable doomsday state for that DB. Run 5 Scenario 8 exists to catch this. -- **Don't trust the migration without checking the sum-invariant log.** The line `sum invariant verified: postSumOs == preSumDem * 10^9 - valueLostOs` (`osDenomination.ts:382`) is the single load-bearing proof point. Absence means the migration aborted, the outer transaction rolled back, the block was not persisted, the validator is stuck at `N-1`. - ---- - -**Last updated**: 2026-05-09. Source-branch: `decimals` @ `b06f488b`. - ---- - -## 9. DEM-665 — `gasFeeSeparation` co-activation - -> **Source branch**: `claude/gas-fee-separation-aDJK5`. Linear: DEM-665. Mycelium epic #10. -> -> **TL;DR**: a second fork named `gasFeeSeparation` rides on the **same `activationHeight`** as `osDenomination`. One coordinated event, one coordinated chain wipe, two state migrations. - -### 9.1 Why bundle - -The plan analysis (see Linear DEM-665 design comment) ruled out putting `fee_config` at the top level of `genesis.json` once `chainGenesis.ts:60-73` was verified to hash `block.content.extra`. Any change to the hashed payload changes the genesis hash and breaks every existing `chain.db`. Since `osDenomination` already requires a coordinated wipe, `gasFeeSeparation` rides on the same wipe with zero extra operator friction. - -### 9.2 What changes in `data/genesis.json` - -Add a second entry under `forks`, at the **same** `activationHeight` as `osDenomination`: - -```json -{ - "forks": { - "osDenomination": { "activationHeight": , "description": "..." }, - "gasFeeSeparation": { - "activationHeight": , - "description": "Gas fee separation (DEM-665). ...", - "treasuryAddress": "0x" - } - } -} -``` - -Validation rules (`src/forks/loadForkConfig.ts:validateGasFeeSeparationEntry`): -- `activationHeight` MUST equal the `osDenomination` activation height (operator policy, not yet auto-enforced; misalignment is a bug). -- `treasuryAddress` MUST match `/^0x[0-9a-f]{64}$/` — strict lowercase, no mixed case (PR #778 G-1/G-4 lesson, myc#6). Mixed case = node refuses to boot with `ForkConfigValidationError`. -- `treasuryAddress` MUST NOT equal `BURN_ADDRESS` (the all-zeros placeholder) when `activationHeight !== null`. Sealing genesis with the placeholder is the most likely operator mistake; the loader fails closed. - -### 9.3 Treasury key custody (ops-owned) - -The placeholder treasury address shipped in `DEFAULT_FORK_CONFIG.gasFeeSeparation.treasuryAddress` is `0x` + 64 zeros. **Replace it with the real treasury ed25519 pubkey before sealing genesis.** The keypair itself lives outside the node repo — ops owns generation, storage, and rotation custody. A production sealing checklist: - -1. Generate a fresh ed25519 keypair (`npm run keygen` or the standalone Demos keymaker). -2. Hex-encode the public key, lowercase, with `0x` prefix. -3. Paste into `genesis.json` under `forks.gasFeeSeparation.treasuryAddress`. -4. Store the private key per the ops key-custody SOP (cold storage / multisig — out of scope for this runbook). - -### 9.4 What the activation hook does - -`src/libs/blockchain/chainBlocks.ts:235-260` runs `osDenomination` FIRST, then `gasFeeSeparation`. The ordering is documented in code: `osDenomination` scales every existing balance × 10^9 to OS units, then `gasFeeSeparation` creates two fresh **OS-denominated** accounts at balance 0: - -- **Burn account** at `0x` + 64 zeros (code constant from `src/forks/migrations/gasFeeSeparation.ts:BURN_ADDRESS`). Spending FROM it is blocked at the GCRBalanceRoutines layer post-fork. Adds to it = burned supply. -- **Treasury account** at the genesis-supplied `treasuryAddress`. Receives the treasury share of every fee distribution. Owned by ops. - -Both creations are idempotent: a pre-seeded account at either pubkey is left untouched. - -The migration writes a row into `fork_state` with `fork_name = "gasFeeSeparation"`, `applied = true`, `applied_at_block = N`. Idempotency on restart works the same way as `osDenomination` — the hook short-circuits if the row exists. - -### 9.5 Pre-flight checklist additions - -On top of §2 of this runbook, add: - -```bash -# 9.5.1 treasuryAddress format check — strict lowercase 0x+64hex -jq -r '.forks.gasFeeSeparation.treasuryAddress' data/genesis.json \ - | grep -E '^0x[0-9a-f]{64}$' \ - || echo "FAIL: treasuryAddress malformed" - -# 9.5.2 same activationHeight as osDenomination -OS_N=$(jq -r '.forks.osDenomination.activationHeight' data/genesis.json) -GFS_N=$(jq -r '.forks.gasFeeSeparation.activationHeight' data/genesis.json) -[ "$OS_N" = "$GFS_N" ] || echo "FAIL: activation heights differ ($OS_N vs $GFS_N)" - -# 9.5.3 treasuryAddress is not the placeholder zero address -TA=$(jq -r '.forks.gasFeeSeparation.treasuryAddress' data/genesis.json) -[ "$TA" = "0x$(printf '0%.0s' {1..64})" ] && echo "FAIL: still on placeholder treasury" -``` - -### 9.6 Post-activation verification - -After block `N` is final on every validator: - -```bash -# Burn account exists with balance 0 -curl -s http://localhost:8079/getAddressInfo \ - -X POST -H 'Content-Type: application/json' \ - -d '{"address":"0x'"$(printf '0%.0s' {1..64})"'"}' \ - | jq '.balance' # expect "0" - -# Treasury account exists with balance 0 (pre-traffic) -TA=$(jq -r '.forks.gasFeeSeparation.treasuryAddress' data/genesis.json) -curl -s http://localhost:8079/getAddressInfo \ - -X POST -H 'Content-Type: application/json' \ - -d "{\"address\":\"$TA\"}" \ - | jq '.balance' # expect "0" - -# fork_state row persisted -psql -c "SELECT fork_name, applied, applied_at_block \ - FROM fork_state \ - WHERE fork_name = 'gasFeeSeparation'" -# expect: gasFeeSeparation | t | N -``` - -After the first post-fork transaction lands, the burn/treasury balances should move per the distribution percentages governed by `NetworkParameters` (see §9.8). - -### 9.7 Rollback - -The activation hook runs inside the same TypeORM transaction as the block insert (`chainBlocks.ts:dataSource.transaction(...)`). If the `gasFeeSeparation` migration throws, the outer transaction rolls back and the activation block is not persisted — same atomicity contract as `osDenomination`. No special node-level rollback procedure; the existing osDenomination one applies verbatim. - -### 9.8 Governable percentages (DEM-665 P13) - -Distribution percentages live in `NetworkParameters`, **not** in the fork payload. Treasury address and burn address are immutable fork-level constants; the per-component splits (50/50, 25/75, 25/50/25 by default) are governance-mutable from day 1 with tighter safety bounds: - -- Per-proposal change cap: **±10%** (vs the ±50% default). -- Per-key absolute bounds: `[0, 100]` on every `*Pct` field. -- Cross-key invariant: each distribution group's percentages must sum to **exactly 100** on the merged (current ⊕ proposed) view. - -A proposal touching only `networkFeeBurnPct` without also adjusting `networkFeeTreasuryPct` is rejected because the merged sum != 100. Proposers must move both keys in the same proposal so the invariant holds. - -### 9.9 Don't-do list additions (gasFeeSeparation-specific) - -- **Don't seal genesis with the placeholder treasury** (`0x` + 64 zeros). The loader refuses to boot. The check exists precisely to catch this operator mistake — overriding it is unsafe. -- **Don't desync the two `activationHeight` values** between `osDenomination` and `gasFeeSeparation`. The chainBlocks hook runs them sequentially in the same block; running them on different heights means osDenomination scales balances at one height and gasFeeSeparation creates OS-denominated accounts at another, which is a recoverable but pointless state confusion. -- **Don't manually edit the burn or treasury rows in `gcr_main`.** Burn balance is reachable only via `add` edits (and rollback inversions of those). Treasury balance is governance-mutated indirectly through fee distribution. Manual SQL edits are not consensus-replayed and will desync the validator. -- **Don't propose to change every distribution percentage in one go.** Even though the bounds permit ±10% per proposal, large simultaneous shifts give observers no window to react. A multi-cycle gradient is safer governance hygiene. - ---- - -**DEM-665 status**: design and implementation merged. Source-branch: `claude/gas-fee-separation-aDJK5`.

The SPEC's risk register also calls them out. - ---- - -## 2. `gcr_edits[]` migration scope - -Per LOG.md Session 9, gcr_edits is the SDK's responsibility to populate with OS-string amounts when post-fork. The node serializer **explicitly does not** transform `gcr_edits[].amount` — it spreads the content verbatim except for the top-level `amount` and `transaction_fee`. So if the SDK puts a `number` into a gcr_edit's `amount` while talking to a post-fork node, the resulting hash will not match the node's expectation. - -### 2.1 Where gcr_edits are constructed - -Single source of truth: `src/websdk/GCRGeneration.ts`. Every `Demos.sign()` flow runs `raw_tx.content.gcr_edits = await GCRGeneration.generate(raw_tx)` (`demosclass.ts:486`). Edits are produced in: -- `GCRGeneration.generate` itself (gas, nonce edits). -- `HandleNativeOperations.handle` (send, tlsn_request, tlsn_store). -- `HandleD402Operations.handle` (d402 payment). -- `HandleStorageProgramOperations.handle` + its `calculateStorageFee` helper. -- Validator-stake / network-upgrade case branches in `generate`. - -There is also one **non-GCRGeneration** site: `src/escrow/EscrowTransaction.ts` builds gcr_edits inline (L85-112, L181-206, L266-289) before calling `demos.sign()`. `demos.sign()` then **overwrites** them via `GCRGeneration.generate` — which means the escrow's manually-built edits are dead code today (subtle bug; flagged for cleanup but not blocking). For P4 we still update those inline construction sites for type-correctness, since they appear in tests. - -### 2.2 Variants that carry per-entry amounts - -Three variants of `GCREdit` carry amounts that need migration: - -1. **`GCREditBalance.amount`** — populated from: - - `GCRGeneration.createGasEdit` — `gasAmount: number = 1` (gas-fee edit, hardcoded 1 DEM). - - `HandleNativeOperations` `case "send"` — passes the user-supplied DEM `amount` straight into `subtractEdit` and `addEdit`. - - `HandleNativeOperations` `case "tlsn_request"` — `TLSN_REQUEST_FEE = 1`. - - `HandleNativeOperations` `case "tlsn_store"` — `storageFee = TLSN_STORE_BASE_FEE + (proofSizeKB * TLSN_STORE_PER_KB_FEE)` in DEM. - - `HandleD402Operations.handle` — payload's `amount`. - - `HandleStorageProgramOperations.handle` — `fee` from `calculateStorageFee`. -2. **`GCREditNonce.amount`** — always `1`; this is a counter increment, **not** a token amount. Plan: keep typed as `number` with JSDoc clarification. (Audit lumped these together; on inspection they are semantically different.) -3. **`GCREditEscrow.data.amount?`** — populated from `EscrowTransaction.sendToIdentity` (when SDK escrow flow is wired into `GCRGeneration` — currently only via the `demos.sign()` overwrite which discards the inline edit, so this is only populated via the handler that actually runs in the node + `Handle*` SDK code; will still need handling once escrow is properly wired). - -### 2.3 Required SDK changes - -- Widen `GCREditBalance.amount` from `number` to `string` (OS, bigint-as-string). -- Update every construction site listed above to populate `amount` as an OS string when the post-fork serializer is active, or as a DEM number when pre-fork (see §3 for the format-switch architecture). -- Keep `GCREditNonce.amount: number` (clarify with JSDoc that it's a count, not an amount). -- Update `GCREditEscrow.data.amount?` to `string` (OS). - -### 2.4 Decision: format choice for gcr_edits - -We have two architectural options: - -- **(A) gcr_edits always carry OS-strings** regardless of node fork status, and the **pre-fork serializer also transforms gcr_edits to legacy DEM-numbers** for hashing. This makes the SDK internal contract uniform but pushes complexity into the pre-fork wire. -- **(B) gcr_edits carry whatever the wire format expects** (number pre-fork, string post-fork). The SDK's GCRGeneration takes the fork state as input and produces the right shape. Internal arithmetic always uses bigint; conversion happens at edit construction time. - -**Recommend (B)**, because: -- The node serializer specifically does not transform `gcr_edits[].amount`. So whatever the SDK puts there *is* the wire format. Option (A) would require a pre-fork SDK-side transformer right before hashing, duplicating node-side logic. -- The current SDK already produces DEM-numbers for pre-fork; that's exactly the legacy contract. Keeping it for pre-fork is zero-risk. -- Post-fork: GCRGeneration receives the fork-state flag and emits OS strings. - -**Concrete plan**: thread the fork-state flag into `GCRGeneration.generate(tx, isRollback, isPostFork)` and propagate to handlers. Default `isPostFork = false` to preserve current callers during the staged rollout (P4 commits 1-3); flip on at the public-API integration commit. - ---- - -## 3. Dual-format serialization strategy - -The SDK must produce different wire formats depending on fork status. This section is the architectural core. - -### 3.1 Detection and caching - -- **RPC**: `demos.nodeCall("getNetworkInfo")` → `NetworkInfo` (envelope unwrapped to `response.data.response` per the existing `nodeCall` flow). The handler is implemented at `node/src/libs/network/handlers/forkHandlers.ts:62`. Response shape: - ```ts - { forks: { osDenomination: { activationHeight: number | null, activated: boolean, currentHeight: number } } } - ``` -- **Cache key**: per-`Demos` instance, scoped by `rpc_url` (mirror the pattern at `_cachedNetworkParametersRpcUrl` in demosclass.ts:1199 — switching network within TTL must invalidate). -- **TTL**: 30s when `activated = true` (won't change again). When `activated = false` and `activationHeight` is non-null, refresh more aggressively as we approach: `min(30s, max(2s, (activationHeight - currentHeight) * blockTime / 4))`. When `activationHeight = null`, TTL = 30s (no fork ever scheduled). -- **First call**: lazy. The first `sign()` call after `connect()` triggers it. The result is cached on the `Demos` instance. -- **Failure modes**: If `getNetworkInfo` errors, returns `{result:500,...}`, or returns a malformed shape: **assume pre-fork** (safest default — produces legacy wire format which the current production node accepts). Log a warning once per `Demos` instance. - -### 3.2 Public API behavior - -- All public-API methods accept `bigint` (OS units): `Demos.transfer(to, amountOs)`, `Wallet.transfer(to, amountOs, demos)`, `EscrowTransaction.sendToIdentity(..., amountOs)`, etc. -- The SDK's internal arithmetic is always `bigint`-OS. -- At the wire boundary (just before `JSON.stringify(raw_tx.content)` for hashing), the format-switch picks pre-fork vs post-fork serialization. - -### 3.3 Serializer chokepoint - -Today the SDK has two hash sites: -- `demosclass.ts:513` — `raw_tx.hash = Hashing.sha256(JSON.stringify(raw_tx.content))` (the active path used by `demos.sign()`). -- `DemosTransactions.sign:130` — `raw_tx.hash = await sha256(JSON.stringify(raw_tx.content))` (deprecated alternate signer; still in code). - -Plan: -- Add a new utility `src/denomination/serializerGate.ts` that mirrors the node's `forks/serializerGate.ts` design: `serializeTransactionContent(content, isPostFork): string`. -- Pre-fork branch: convert any internal `bigint` amounts back to DEM `number` (since the SDK has been bigint-internally even pre-fork after the migration), then `JSON.stringify(content)`. -- Post-fork branch: convert internal `bigint` to OS decimal string, then `JSON.stringify(content)`. -- Both hash sites call `serializeTransactionContent` instead of `JSON.stringify(raw_tx.content)`. -- The `gcr_edits[]` array is part of `content`; gates need to align with §2.4 option (B). The serializer takes already-correctly-shaped edits and just stringifies. Construction-time correctness is the contract. - -### 3.4 Pre-fork sub-DEM rejection - -When pre-fork mode and `amountOs % OS_PER_DEM !== 0n`, reject: -``` -SubDemPrecisionError: pre-fork node cannot accept sub-DEM precision (amount = 1234567 OS = 0.001234567 DEM). Either upgrade to a post-fork node or round to whole DEM. -``` -This guard runs in the public API entry points (`Demos.transfer`, `Wallet.transfer`, `EscrowTransaction.sendToIdentity`, …) **after** fork detection, **before** building the transaction. - -### 3.5 Canonical key order - -LOG.md Session 9 recorded the canonical wire key order: -``` -type, from, to, amount, data, nonce, timestamp, transaction_fee, from_ed25519_address, gcr_edits -``` -The SDK's `skeletons.ts` already produces this order via insertion. Migration must preserve insertion order at every construction site (no `Object.assign`, no spread that reorders, no late additions). **Add an integration test that asserts `Object.keys(content)` matches the canonical sequence after `sign()`.** - -The skeleton currently lacks `from_ed25519_address` and `gcr_edits`; those are added in `sign()` after construction. Keep that order — `from_ed25519_address` is set at sign:421-426, `gcr_edits` at sign:486 (right before the fee calc and hash). This matches the node's canonical order. - ---- - -## 4.

Test strategy - -### 6.1 Unit (new + updated) - -- `src/denomination/conversion.test.ts` — already exists from P0; extend with edge cases (negative inputs, max-uint256-ish bigint inputs). -- New: `src/denomination/serializerGate.test.ts` — pre-fork branch produces legacy bytes byte-identical to today's `JSON.stringify(content)`. Post-fork branch produces OS-string bytes byte-identical to the node's `serializeTransactionContent`. Use a fixed canonical TransactionContent fixture; assert on the exact string. -- Update: every existing tx-construction test (`tests/native.spec.ts`, `tests/storagePrograms.spec.ts`, etc.) to use bigint OS where it previously used DEM number. - -### 6.2 Compatibility — pre-fork node - -- Mock `getNetworkInfo` returning `activated: false, activationHeight: null`. -- Build a transfer tx via `demos.transfer(to, demToOs(100))`. -- Assert wire bytes (the `JSON.stringify` input to `Hashing.sha256`) carry `amount: 100` (number, DEM), not `"100000000000"`. -- Assert the same for fee fields and gcr_edits balance amounts. -- Assert `demos.transfer(to, 1n)` (sub-DEM precision) throws `SubDemPrecisionError`. - -### 6.3 Compatibility — post-fork node - -- Mock `getNetworkInfo` returning `activated: true, currentHeight: 100, activationHeight: 50`. -- Build same transfer. -- Assert wire bytes carry `amount: "100000000000"` (string, OS). -- Assert gcr_edits[].amount entries are OS strings. -- Assert `demos.getAddressInfo(addr)` parses a post-fork response (`{ balance: "100000000000" }`) into `bigint(100000000000n)` for `info.balance`. - -### 6.4 Round-trip with node serializer - -- For a fixed TransactionContent fixture (chosen to exercise amount, fee, multi-edit gcr_edits, all key-order positions): - 1. SDK v3 (post-fork mode) computes `hashSdk = sha256(serializeTransactionContent(content, true))`. - 2. Independently, paste the same fixture into a node-side test that calls the node's `serializeTransactionContent(content, blockHeight=N+1)` → `hashNode`. - 3. Assert `hashSdk === hashNode`. -- This is the ground-truth that SDK signatures will validate on the post-fork node. It would be best wired as an SDK test that imports the same fixtures the node tests use (cross-repo coupling — accept this). - -### 6.5 Detection / caching tests - -- `getNetworkInfo` called once per `Demos` instance under TTL. -- Fork-status cache invalidates on `rpc_url` change. -- Failing `getNetworkInfo` assumes pre-fork; logs once per instance. -- TTL shrinks as `currentHeight` approaches `activationHeight`. - -### 6.6 Key-order regression - -- `Object.keys(signedTx.content)` matches `[type, from, to, amount, data, nonce, timestamp, transaction_fee, from_ed25519_address, gcr_edits]` after `demos.sign()`. - ---- - -## 7. Build / version / publish - -- `package.json`: bump `"version": "2.12.2"` → `"3.0.0-rc.1"`. -- Publish: `bun publish --tag rc` (so caret consumers don't auto-pull). -- Build: no scripts change. Same `tsc --skipLibCheck && resolve-tspaths && …` pipeline; new files in `src/denomination/` get picked up automatically. -- Exports: `src/index.ts` already exports `denomination`. Add `serializerGate` either inside `denomination` (probably best — keeps it co-located) or as a new module. Recommendation: keep it inside `denomination` and **do not** add a top-level export — it's internal infrastructure, not user-facing API. - ---- - -## 8. Risk register - -| # | Risk | Mitigation | -|---|---|---| -| R1 | gcr_edits embedded amount nesting (Session 9 flag) | §2 enumerates every construction site; tests assert OS-string at every spot. | -| R2 | Key-order canonicalization drift between SDK & node | §3.5 + §6.6 explicit canonical-order test; cross-repo round-trip test §6.4. | -| R3 | XM (Solana lamports, Aptos octas, XRP drops, etc.) accidentally converted to OS | §1.7 explicit non-target list; lint rule for any `demToOs` call inside `src/multichain/` should fail review. | -| R4 | TON/Tron/NEAR top-level `amount` fields on `tx.content` for cross-chain ops | These flow through `TransactionContent.amount` which **does** become OS string post-fork — but in those flows the user's DEM payment is the `amount`, while the cross-chain target amount lives in the `data` payload (chain-specific units). Reviewer must confirm during implementation that no chain-specific amount has been misrouted into `content.amount`. | -| R5 | Pre-fork node receiving a v3-built tx with sub-DEM precision | §3.4 hard error before tx construction; never reaches the wire. | -| R6 | `getNetworkInfo` failure mode wrong default | Default to pre-fork (legacy format) so old nodes continue working; explicit warn-log so users notice. | -| R7 | Fork status cache stale across `connect()` to a different RPC | TTL keyed on `rpc_url`; mirrors existing pattern in demosclass.ts. | -| R8 | `Wallet.transfer()` sets `tx.content.from = demos.keypair.publicKey…` overwriting the field — this is unrelated but visible during the migration. Don't fix in P4. | Note in commit message; defer. | -| R9 | Storage program `FEE_PER_CHUNK = 1n` is currently 1 OS not 1 DEM (pre-existing bug) | P4 fixes by replacing with `OS_PER_DEM`. Increases storage fees by 10^9 — call out in changelog. | -| R10 | Node-side `STORAGE_PROGRAM_FEE_PER_CHUNK` in `GCRStorageProgramRoutines.ts` is `1n` and unchanged by the migration. After fork, node will charge 1 OS per chunk while pre-fork it charged 1 DEM (= now 1 OS in stored balance). Fee crashes by 10^9. | This is a **node-side** issue not in P4 scope; flag for P5/P6. P4 still aligns SDK constants with `OS_PER_DEM` (the user-intended 1 DEM/chunk). The post-fork SDK will produce edits that node will only charge 1 OS for — fee under-collection. Document this for P5 to address. | -| R11 | Skeleton `transaction.content.amount: 0 // number` initialises a numeric. Post-fork serializer will see `0` and need to coerce. | Either (a) remove the skeleton field and require callers to set it, or (b) initialise as `0n` bigint and coerce at serialize-time. (a) is cleaner; pick during implementation. | -| R12 | `_calculateAndApplyGasFee` fallback uses `Number(edit.amount)` and silently drops precision for OS-magnitude values | Migrate the math to BigInt; this fallback runs rarely (only when `getNetworkParameters` is missing) but values are large enough to overflow Number once they're OS. | -| R13 | Tests in `src/tests/*.spec.ts` use DEM number literals; many assertions on `amount: 100` etc. | Sweep + replace under §6.1 update step. Risk: missed test that silently keeps passing because `Number == String` fails type-check. TS strict mode catches these at build. | -| R14 | Public consumers of v2.x (e.g., docs, examples) reference `amount: number` | Update README, examples, JSDoc as part of the same release. P7 (final v3.0.0) is the formal docs sweep but RC ships with usable docs. | - ---- - -## 9. Phasing within P4 (commit sequence) - -P4 is one shippable RC. For review hygiene we propose 5 commits. Each is reviewable but only the final commit leaves the SDK fully buildable + tests green; intermediate commits use TS escapes (`@ts-expect-error`, `as unknown as ...`) where required. Call this out in commit messages. - -### Commit 1 — `feat(types): widen amount/fee/balance fields to OS string` -Updates: `TxFee.ts`, `Transaction.ts`, `rawTransaction.ts`, `statusNative.ts`, `StateChange.ts`, `D402PaymentTransaction.ts`, `bridgeTradePayload.ts`, `EscrowPayload`, `GCREdit.ts` (Balance/Escrow), `nativeBridgeTypes.ts` (EVMTankData/SolanaTankData/legacy), `CustomCharges.ts` (rename). -**Buildable**: NO. Will produce many type errors at construction sites — that's the point. Use `@ts-expect-error` on the offending sites with a TODO referencing commit 2. - -### Commit 2 — `feat(construction): bigint internal arithmetic + OS-string emission at boundaries` -Updates: `GCRGeneration.ts` (all handlers), `EscrowTransaction.ts`, `nativeBridge.ts`, `skeletons.ts`, `DemosTokens.ts`, `Identities.ts`, `l2ps.ts`, `_calculateAndApplyGasFee` in `demosclass.ts`. Tests still using DEM-number literals are temporarily skipped with a `// TODO P4 commit 5` marker. -**Buildable**: YES (with the test-skips). Existing tests in `tests/` may break — re-enable in commit 5. - -### Commit 3 — `feat(serializer): dual-format serializerGate` -Adds: `src/denomination/serializerGate.ts` (mirrors node design, includes pre-fork `bigint→number` coercion and post-fork `bigint→OS-string` coercion). Wires both hash sites in `demosclass.ts` and `DemosTransactions.ts` to use it. Default `isPostFork = false` until commit 4. -**Buildable**: YES. - -### Commit 4 — `feat(rpc): getNetworkInfo fork detection + sub-DEM guard + public API bigint` -Adds: `Demos.getNetworkInfo()` (typed RPC wrapper), `Demos._cachedForkStatus` + TTL+rpc-url-keyed cache, `_getForkStatusCached` helper. Threads cached fork status into `sign()` → `serializerGate` → `GCRGeneration`. Flips public API: `Demos.transfer(to, amountOs: bigint)`, `Wallet.transfer(..., amountOs: bigint, ...)`, `EscrowTransaction.sendToIdentity(..., amountOs: bigint, ...)`. Adds `SubDemPrecisionError`. Fixes `getAddressInfo` FIXME by parsing OS-string when `activated`, BigInt-DEM-multiplied otherwise; or accepting either shape and normalizing. -**Buildable**: YES, with new tests for compatibility paths. - -### Commit 5 — `chore: tests + version bump + jsdoc` -Re-enables/rewrites all skipped tests. Adds the new tests from §6.1-6.6. Bumps `package.json` to `3.0.0-rc.1`. JSDoc + examples updated. `CHANGELOG.md` entry. -**Buildable**: YES. Tests green.

However, **critical precision loss vulnerabilities exist in transaction validation** due to `parseInt()` calls that assume `number` types for large amounts.

For fees this is less critical (fees are typically small) but still a latent bug. - -**Fix required:** Change to `bigint` columns. - -### Fee Calculation - -**File:** `/Users/tcsenpai/kynesys/node/src/libs/blockchain/routines/calculateCurrentGas.ts` -```typescript -const transactionFee = payloadSize * composedGasPrice -``` - -No denomination conversion.

Wire Deserialization - -**Status:** WILL BREAK — Hardcoded number assumptions - -### Transaction Deserialization Path - -When SDK sends a transaction with `amount: "1000000000"` (string, Phase 1.1), the node must: - -1. **Parse RPC request** — Done via JSON.parse (safe, strings stay strings) -2. **Store in mempool** — Content is stored as-is (safe) -3. **Validate in subOperations** — **BREAKS HERE** (line 96): - ```typescript - const amount = parseInt(operation.params.amount, 10) - ``` - This works for string input but loses precision for large values. - -4. **Create Transaction entity** — Content stored as JSON (safe) -5. **Compare balances** — **BREAKS HERE** (line 65, GCRBalanceRoutines): - ```typescript - if (actualBalance < editOperation.amount) // type mismatch if amount is string - ``` - -### No Type Guards - -The node does not validate that incoming `amount` is the expected type.

Unlikely in practice (max ~9×10^15 OS ≈ 9,000 DEM) but theoretically broken. - -### Units in Genesis Data - -The node assumes `genesisData.balances[i][1]` is in the same denomination as the active network. When SDK migrates to OS, genesis files must be recalculated or converted. No automatic conversion happens. - ---- - -## 8.

If balance values change (due to genesis recalculation), all state hashes change. - -**Implication:** Any consensus algorithm that commits to state hashes will see a fork. - ---- - -## 9. GCRv2 & State Changes - -**Status:** READY ✓ (with caveats) - -### nativeAmount Field - -Per IDEA.md Phase 1.6, the SDK defines `StateChange.nativeAmount: string`. The node does not define or import StateChange directly; it works with GCREdit instead: - -**SDK Type (not used by node yet):** -```typescript -interface StateChange { - nativeAmount: string; // OS amount as string - sender: BinaryBuffer; - receiver: BinaryBuffer; -} -``` - -The node's GCREdit handling (GCRBalanceRoutines) converts amounts to BigInt, so will be compatible once SDK sends strings. - -### GCREdit Type Assumptions - -**File:** `/Users/tcsenpai/kynesys/node/src/libs/blockchain/gcr/gcr_routines/GCRBalanceRoutines.ts` (line 26, 65) -```typescript -if (editOperation.amount <= 0) { - return { success: false, message: "Invalid amount" } -} -if (actualBalance < editOperation.amount || actualBalance === 0n) { -``` - -Line 65 compares `bigint` (actualBalance) with `editOperation.amount`.

Native Bridges (Multichain) - -**Status:** MINIMAL CODE — Safe - -**File:** `/Users/tcsenpai/kynesys/node/src/features/multichain/routines/executors/pay.ts` - -Bridge executors delegate to SDK's xm-localsdk. The node does not compute bridge amounts; it passes operation payloads through. Bridge-specific denomination handling is in the SDK. - -**Risk:** If node and SDK versions mismatch during migration, bridge operations might serialize amounts differently. - ---- - -## 11. Storage Program & TLSNotary Fees - -**Status:** NOT FOUND — Fees handled elsewhere - -The node does not define `STORAGE_PROGRAM_CONSTANTS` or `calculateStorageFee()` mentioned in IDEA.md Phase 2. These are SDK concepts. The node enforces custom charges through generic GCREdit operations. - -### IPFS Custom Charges - -No references to `max_cost_dem`, `max_cost_os`, or `IPFSCustomCharges` found in the node codebase. These are SDK-side. The node passes them through in transactions without interpretation. - -### TLSNotary Fees - -**File:** `/Users/tcsenpai/kynesys/node/src/features/tlsnotary/constants.ts` - -Only service constants (ports, timeouts, buffer sizes). No fee definitions. TLSNotary pricing is handled by the SDK and stored in custom charges. - -**Implication:** Node changes are not required for Phase 2 unless the TLSNotary integration layer in the SDK changes. - ---- - -## 12. SDK Version & Denomination Utilities - -**Status:** NOT MIGRATED - -**package.json:** -```json -"@kynesyslabs/demosdk": "^2.11.4" -``` - -The SDK v2.11.4 does NOT export: -- `demToOs()` -- `osToDem()` -- `OS_PER_DEM` -- `denomination` module - -The node does not import any denomination utilities. After SDK deploys Phase 0, the node must: -1. Update SDK version to the new major version -2. Import and use `demToOs()`, `toOsString()`, `parseOsString()` in all amount-handling code - ---- - -## 13. Tests - -**Status:** PARTIAL READINESS ✓ - -### Token Tests - -**File:** `/Users/tcsenpai/kynesys/node/testing/loadgen/src/token_shared.ts` (lines 59-62, 74-76) -```typescript -if (typeof balRaw === "string") { - try { - const bal = BigInt(balRaw) - if (bal >= minBalance) return - } -} -``` - -Tests already handle `balance` as string and parse via BigInt. Tests are **ready** for SDK migration. - -### Amount Tests - -No explicit tests for amount parsing/validation found in the audit scope. Need to audit: -- `src/tests/*.ts` — unit tests -- `jest` test files — integration tests - -Tests that hard-code numeric amounts (e.g., `amount: 100`) will fail after SDK migration unless converted to `amount: "100000000000"`. - ---- - -## Cutover Risks - -### 1. **Silent Precision Loss (CRITICAL)** - -**Risk:** `parseInt(operation.params.amount)` truncates large OS amounts. - -**Example:** OS amount `10000000000000000n` (sent as string by SDK) becomes `10000000000000000` via parseInt, but if the string came from a larger BigInt, the precision is lost silently. - -**Mitigation:** Replace all `parseInt(amount)` with `BigInt(amount)` or `BigInt(operationAmount)`. Add assertions to validate round-trip: `BigInt(amount) === BigInt(amountString)`. - -**Probability:** High if amounts approach or exceed 2^53 in OS units (unlikely but possible). - ---- - -### 2. **Transaction Hash Mismatch (CRITICAL)** - -**Risk:** Transaction hashes computed by node differ from SDK after amount serialization changes. - -**Scenario:** -- SDK v2.11.4: Sends `tx.content = {amount: 100, ...}` -- Node hashes: `sha256("{\"amount\":100,...}")` -- SDK v3.0.0: Sends `tx.content = {amount: "100000000000", ...}` -- Node hashes: `sha256("{\"amount\":\"100000000000\",...}")` -- **Hashes don't match!** - -**Mitigation:** Hard-fork protocol. At the block boundary where SDK deploys, recompute hashes using the new serialization. Update node consensus validation to accept both old and new formats during transition window. - -**Probability:** Certain if SDK and node don't migrate atomically. - ---- - -### 3. **Type Confusion in Balance Comparisons (CRITICAL)** - -**Risk:** `actualBalance < editOperation.amount` when types differ. - -**Scenario:** -- `actualBalance: 1000000000n` (bigint, OS) -- `editOperation.amount: "500000000"` (string, OS) -- Comparison: `1000000000n < "500000000"` → `false` (string < comparison) -- Funds subtracted despite insufficient balance check passing. - -**Mitigation:** Coerce all amounts to BigInt in GCRBalanceRoutines and subOperations. Add type assertions. - -**Probability:** High if SDK sends strings and node doesn't validate. - ---- - -### 4. **Database Truncation (MODERATE)** - -**Risk:** Fee columns are `integer` (32-bit); large OS fees are silently truncated. - -**Example:** RPC fee `1000000000` OS stored in `integer` column → truncated or error. - -**Mitigation:** Migrate fee columns to `bigint`. - -**Probability:** Moderate; fees are typically small but OS amounts are much larger. - ---- - -### 5. **JSON Serialization Failure (HIGH)** - -**Risk:** `JSON.stringify(tx.content)` throws TypeError if `amount` is bigint. - -**Scenario:** -- Node constructs `tx.content.amount = 1000000000n` (bigint) -- `JSON.stringify(tx.content)` → TypeError -- Transaction cannot be hashed or sent. - -**Mitigation:** Ensure amounts are always strings or numbers before JSON serialization. Use `toOsString()` from SDK. - -**Probability:** High if node code constructs bigint amounts and tries to serialize. - ---- - -## Coordinated Migration Order - -### Recommended Approach: **Node & SDK Ship Together** - -The breaking changes (hash incompatibility, type changes) are unavoidable. A staged approach is not feasible. - -#### **Day 1: SDK Releases Major Version** - -1. SDK v3.0.0 (Phase 0–8 complete): - - Exports `demToOs()`, `osToDem()`, `parseOsString()`, `toOsString()` - - All amount fields in types are `string` (wire format) - - Tests pass with new serialization - - **NOT deployed to mainnet yet** - -2. Node team: - - Review and audit this new SDK version - - Prepare node patches for precision loss, type mismatches - - Hold release in staging - -#### **Day 2: Coordinated Deployment** - -1. SDK v3.0.0 deployed to **all SDKs and clients** -2. Node patches deployed to **all nodes** in a synchronized hard fork: - - Update `subOperations` to use `BigInt()` instead of `parseInt()` - - Add type guards in GCRBalanceRoutines - - Update fee column definitions (bigint) - - Update RPC response serialization to convert bigint to string - - Update config defaults: `rpcFee: 10000000000` (10 DEM in OS) - -3. Genesis recalculated using new SDK conversion utilities - -4. Consensus checkpoint at fork block - -#### **What Breaks If Order Is Wrong:** - -**If SDK deploys first (without node):** -- SDK sends `amount: "1000000000"` strings -- Node's `parseInt()` works but becomes lossy -- Node's GCR balance comparisons fail (type mismatch) -- Transactions hang or are rejected -- RPC errors when trying to JSON.stringify bigint - -**If node deploys first (without SDK):** -- Node expects strings but SDK sends numbers -- Node's BigInt coercions work (no error) but interpret DEM as OS -- Balances are 10^9x wrong -- Consensus breaks immediately - -#### **Safest Order: Deploy Simultaneously** - -1. Select a block N -2. Both SDK and node deploy code that **supports both formats** in a transition window: - - Node accepts both `amount: number` and `amount: string` - - SDK sends the new string format - - Node validates the format dynamically -3. At block N, force the new format exclusively -4.

Still `balance: number` (max ~9.007e15). - -**New fields from staking PR**: NONE. The legacy backend does not store validator stakes — those live in the `Validators` table. No new JSONB fields were added. - -**Implication**: Legacy backend still has the same MAX_SAFE_INTEGER ceiling. Any account with > ~9M DEM pre-fork will overflow if migrated via the legacy path. This is pre-existing (not introduced by staking PR) but still a blocker for P3b. - ---- - -## Q3: GCRv2 (Modern) Backend - -**File**: `src/model/entities/GCRv2/GCR_Main.ts` - -```typescript -@Column({ type: "bigint", name: "balance" }) -balance: bigint -``` - -**Status**: UNCHANGED. Still `bigint`, still the only modern balance store. - -**New fields from staking PR**: NONE. No staking-related columns in GCRv2. - -**Implication**: GCRv2 migration is straightforward: `UPDATE gcr_main SET balance = balance * 1000000000n`. No new columns to handle. - ---- - -## Q4: Block-Acceptance Hook Site - -**File**: `src/libs/blockchain/chainBlocks.ts:148–347` - -The `insertBlock()` function now includes three new governance-related operations **within the transaction context** (lines 301–311): - -```typescript -// Line 301-311 -const govProposalRepo = transactionalEntityManager.getRepository(NetworkUpgrade) -const govVoteRepo = transactionalEntityManager.getRepository(NetworkUpgradeVote) -await tallyUpgradeVotes(block.number, govProposalRepo, govVoteRepo) -await applyNetworkUpgrade(block.number, govProposalRepo) -``` - -**No new pre-block hooks** that would conflict with state migration. Both governance calls happen **after** block persistence (line 213–314 all in one transaction), so our fork-activation migration hook can still run at line 148 (block entry) or inline before line 213 (pre-save). - -**Recommended hook site**: Still **`Chain.insertBlock` at line 148**, before block persistence. The migration check and execution should run in the transaction context (same as governance hooks) so it rolls back if the block save fails. - -**Order**: -1. Check fork activation (migration idempotent gate) -2. Run state migration if needed (all balances, all stakes, one atomic UPDATE per table) -3. Persist block -4. Tally votes & apply governance - -**No ordering conflict**: Governance reads from `NetworkUpgrade` (no balance-related columns). State migration reads from `GCRMain` and `Validators` (both pre-block state). No race. - ---- - -## Q5: New TypeORM Migrations Introduced by the Staking PR - -**Pre-merge baseline**: Commit 28a161f4. -**Post-merge**: Commit 4b099c5d. - -**Files created/modified under `src/migrations/`**: - -| File | Status | Purpose | Impact on P3b | -|---|---|---|---| -| `WidenFeeColumnsToBigint.ts` | Pre-existing (P-1) | Widen fee columns from 32-bit to 64-bit | No new migrations added by staking PR | -| `AddReferralSupport.ts` | Pre-existing | (unrelated) | No new migrations added by staking PR | - -**New migrations from staking PR**: **ZERO**. - -The staking PR modified `Validators.stake` → `Validators.staked_amount` (schema change) but **did not include a TypeORM migration file**.

Legacy GCR JSONB Overflow (Pre-Staking, Still Blocking) - -**Status**: NOT RESOLVED by staking PR. - -The legacy `GlobalChangeRegistry.details.content.balance` is still a JS `number` (max ~9.007e15). After ×10^9, any account > ~9M DEM will overflow. - -**Options**: -- (a) **Fail-loud**: Migration aborts if any account > 9M DEM. Operators must manually fix legacy backend or prove no such accounts exist in genesis/production. -- (b) **Widen to JSONB string**: `ALTER TABLE global_change_registry SET (details.content.balance = balance::text)` before migration, then multiply. -- (c) **Skip legacy backend**: If legacy backend is already superseded by GCRv2 for all accounts in the deployment, skip legacy migration. - -**Recommendation**: Fail-loud (option a). Legacy backend is being phased out. If it has > 9M DEM accounts, that's a risk signal. - -**What we need from you**: Confirm option (a) or decide differently. - -### 2. Validator Stake Unit Confirmation - -**Status**: RESOLVED by code inspection. Traces confirm: -- SDK (v2.12.2) sends stake amounts as **DEM-denominated bigint strings** -- Node stores in `Validators.staked_amount` as text (no conversion) -- Post-fork, SDK v3 will send OS-denominated amounts - -**Confirm**: This matches your expectation, or flag if stake amounts should follow different denomination rules than account balances. - -### 3. Hook Timing Within `insertBlock` Transaction - -**Status**: Clarification needed. - -Our migration must run inside the `dataSource.transaction()` block (line 213–315) so it's atomic with block persistence. Two options: - -- (A) Run migration **before** line 213 (pre-block-save), inside outer try/catch -- (B) Run migration **within** the transaction context (line 215–314), as a separate operation - -**Recommendation**: Option B (inside transaction). This ensures the migration and block both succeed or both roll back together. - -**What we need from you**: Confirm or specify if there's a reason to prefer option A. - -### 4. Network Upgrade Voting — Stake Denomination - -**Status**: PARTIAL CLARITY. - -`NetworkUpgradeVote.weight` is stored as text (bigint-as-string), capturing the voter's staked amount at the snapshot block. This will be DEM pre-fork, OS post-fork. - -**Question**: Should tally logic adjust vote weights at fork if a voter's stake changed between pre-fork and post-fork? (E.g., a voter stakes 100 DEM pre-fork, the fork happens, stake becomes 100 OS, then they vote — should vote weight be 100 DEM or 100 OS?) - -**Current code** (`src/features/networkUpgrade/governanceWeight.ts`) reads `staked_amount` at the snapshot block and freezes it. This is deterministic and safe, regardless of denomination. - -**What we need from you**: Confirm this is the intended behavior (immutable weight at snapshot) or flag if vote weights should be denomination-adjusted. - ---- - -## Risk Register Update - -### New Risks Introduced by Staking PR - -| Risk | Severity | Mitigation | -|---|---|---| -| **Validators table migration coupling** | HIGH | Stakes and balances must migrate atomically. Test with a validator who has both a balance and a stake. | -| **Governance vote weights post-fork** | MEDIUM | Vote weights frozen at snapshot are safe, but confirm this is the intent with governance stakeholders. | -| **New entities not migrated** | LOW | `NetworkUpgrade` and `NetworkUpgradeVote` are governance metadata (not denominated). No migration needed. | -| **Legacy GCR JSONB still overflowing** | HIGH | Same as before staking PR. Blocks P3b unless resolved. | - -### Old Risks Now Resolved - -| Risk | Resolution | -|---|---| -| **`Validators.stake` write semantics unknown** | RESOLVED. Staking PR shows exact design: column renamed to `staked_amount`, type = text, denomination = DEM pre-fork / OS post-fork. | -| **Fee widening blocking P-1** | RESOLVED. Already in place (P-1 committed). `Transactions` fee columns are `bigint`. | -| **New entities hiding DEM-denominated state** | RESOLVED. Staking PR added only governance entities (`NetworkUpgrade`, `NetworkUpgradeVote`) and validator state machine — no hidden balance/fee columns. | -| **Validator set hash algorithm breaking at fork** | RESOLVED. `getGCRHashedStakes()` is denomination-agnostic. Hash changes (expected), code doesn't. | - ---- - -## Summary for User - -### The Headline Question - -**Q: Is `Validators.stake` in DEM or OS post-merge?** - -**A**: In **DEM** (pre-fork). The old `stake: number` column was removed and replaced by `staked_amount: string` (bigint-as-string, DEM-denominated). It holds DEM values today. Post-fork, new stakes will be OS-denominated (SDK v3 will send OS amounts), but historical stakes must be migrated ×10^9 at the fork boundary. - -### Staking PR Impact on P3b Scope - -**New DEM-denominated state**: 1 column (`Validators.staked_amount`). -**New DEM-denominated entities**: 0 (governance entities added, but not denominated). -**New bigint columns needing migration**: 0 (all existing bigints handled by P-1). - -### Planned Hook Site Still Good - -✓ **`Chain.insertBlock` at line 148 is still the right place.** No new pre-block hooks conflict. Governance operations (vote tally, proposal apply) happen after block persistence and don't read stale state. - -### Top 3 Changes to the Migration Plan - -1. **Must migrate `Validators.staked_amount` ×10^9**: It was unknown in the original audit. Staking PR shows it's a full stake ledger (text bigint-as-string). Add to migration scope. -2. **No new TypeORM migrations from staking PR to coordinate with**: Simplifies our dependency graph. Our `CreateForkStateTable` migration can run standalone. -3. **Legacy GCR overflow still a blocker**: Staking PR didn't resolve it. We still need operator decision: fail-loud, widen JSONB, or skip legacy backend. - -### Blockers for P3b Resume - -1. **Legacy GCR overflow decision** (pre-staking, still open): Can we proceed assuming no account > 9M DEM in legacy backend, or must we widen JSONB first? -2. **Migration atomicity within `insertBlock` transaction** (clarification): Confirm Option B (run migration inside transaction) is acceptable. -3. **Governance vote weight semantics** (optional): Confirm immutable-at-snapshot is the intended behavior. - -**Everything else is a GO for P3b implementation.** - diff --git a/decimal_planning/audit_sdk.md b/decimal_planning/audit_sdk.md deleted file mode 100644 index 13e2e234..00000000 --- a/decimal_planning/audit_sdk.md +++ /dev/null @@ -1,738 +0,0 @@ -# DEM → OS Denomination Migration Audit - -**Date**: May 1, 2026 -**Auditor**: Claude Code (Read-Only Audit) -**SDK Version Audited**: 2.11.5 -**Source Location**: `/Users/tcsenpai/kynesys/sdks/` - ---- - -## Executive Summary - -The SDK is in a **greenfield state** for denomination migration—no `denomination/` module exists, no conversion utilities are implemented, and all amount/fee/balance fields remain as `number` types (DEM).

Node must migrate hashing logic simultaneously. -- **Location**: `src/websdk/demosclass.ts:375` -- **Required Action**: Coordinate with node team on hashing strategy before release. - -### 2. **No Denomination Module Exists** (Blocking) -- **Issue**: Phase 0 (src/denomination/) is completely missing. All conversion utilities (`demToOs`, `osToDem`, `toOsString`, `parseOsString`) don't exist. -- **Impact**: Cannot begin any phase of the migration without these utilities. -- **Required Action**: Create Phase 0 module as a prerequisite for all other phases. - -### 3. **getAddressInfo Balance Conversion Has FIXME Bug** (High) -- **Issue**: Line 808 in demosclass.ts converts balance to BigInt but has a documented FIXME for when balance is 0 (falsy check fails). -- **Impact**: Zero balances may not round-trip correctly. -- **Location**: `src/websdk/demosclass.ts:815` (FIXME comment) -- **Required Action**: Fix zero-balance handling before deploying. - -### 4. **Hidden Surface Area: 6+ Types with Amount Fields Not Listed** (High) -- **Issue**: D402PaymentPayload, BridgeTradePayload, GCREdit subtypes, StateChange token/NFT amounts, and xm apiTools all have `amount: number` fields not mentioned in the doc. -- **Impact**: Incomplete migration will leave orphaned number amounts in production code. -- **Required Action**: Audit and add all amount fields to the migration checklist. - -### 5. **IPFS Custom Charges Denomination Ambiguous** (Medium) -- **Issue**: CustomCharges.ts labels costs as `max_cost_dem` and "DEM wei", but no conversion is applied. Unclear if node returns DEM or OS. -- **Impact**: May pass wrong denomination to node during cost estimation. -- **Location**: `src/ipfs/IPFSOperations.ts:557–602`, `src/types/blockchain/CustomCharges.ts:22–43` -- **Required Action**: Clarify with node whether IPFS quotes are DEM or OS, and apply conversion if needed. - ---- - -## Recommendation - -**Do not begin Phase 1–10 migrations until Phase 0 is complete and approved.** The lack of denomination utilities blocks all downstream work.

The `content` object structure is defined in the TypeScript `TransactionContent` type from the SDK (`@kynesyslabs/demosdk/types`). - -**Single call site for block hashing**: -- `Hashing.sha256(JSON.stringify(block.content))` — appears in ~2 locations: - - `createBlock.ts` (consensus block creation) - - `chainGenesis.ts` (genesis block) - -All routes use `JSON.stringify(block.content)`. The `content` object is `BlockContent` from the SDK. - -### 3.2 Fork Gate Placement - -A fork gate for serialization can be inserted **before the `JSON.stringify()` call**, wrapped in a utility function: - -```typescript -// New file: src/libs/blockchain/serialization/serializerGate.ts -export async function serializeTransactionContent( - content: TransactionContent, - blockNumber?: number -): Promise { - const height = blockNumber ?? await Chain.getLastBlockNumber() - - if (height >= FORK_HEIGHTS.osDenomination) { - // Use new format (amount as string) - return JSON.stringify(transformToNewFormat(content)) - } else { - // Use old format (amount as number) - return JSON.stringify(content) - } -} -``` - -**Effort**: Replace 6 call sites with calls to `serializeTransactionContent()`.

Database / State Implications (Block Sync & Dual Rules) - -**Key Challenge**: After upgrade, the node must validate historical blocks (pre-fork) with old rules and new blocks (post-fork) with new rules. - -### 5.1 Block Sync of Historical Blocks - -When a node syncs, it replays blocks sequentially: - -**File**: `/Users/tcsenpai/kynesys/node/src/libs/blockchain/routines/Sync.ts` (28919 bytes) - -The sync routine fetches blocks from peers and calls `Chain.insertBlock()`.

Apply blocks 10001-11999 using **old serialization rules** -2.

The serialization gate sits **above** the database layer, so: - -- **Pre-fork blocks in DB**: Store the old serialized content (amount as number) -- **Post-fork blocks in DB**: Store the new serialized content (amount as string) -- **No schema migration needed**: The `content` column is agnostic to the inner structure - -When reading from DB and revalidating, pass the block height to the serializer — it will use the correct format. - -**Effort**: Add optional `blockNumber` parameter to validation functions; thread through 3-4 call sites. - ---- - -## 6. Effort Estimate (T-Shirt Sizing) - -Based on findings (1)-(5): - -| Task | Effort | Notes | -|------|--------|-------| -| Add `forks` config to genesis.json | S | 10 min — simple JSON extension | -| Load fork heights into `SharedState` | S | ~1 hour — trivial initialization code | -| Create serialization gate function | M | ~2 hours — wrap `JSON.stringify()`, thread block height | -| Update transaction hashing sites | S | ~1 hour — ~6 call sites, mechanical replacements | -| Update block hashing sites | S | ~30 min — ~2 call sites | -| Update validation/coherence checks | M | ~2 hours — pass blockNumber through call chain | -| Testing (unit + integration) | M | ~4-6 hours — dual-format validation, sync regression | -| **Total** | **M** | **~12-15 hours (~2 person-days)** | - -**Rating: MEDIUM (M)**. No showstoppers. Block height is already available at all critical sites. Serialization is a single choke point. Database is format-agnostic. - ---- - -## 7. Alternative: Dual-Format Acceptance Window - -This approach asks: "Can the node accept both wire formats (amount as number OR string) during a transition window?" - -### 7.1 Feasibility Assessment - -**Idea**: SDK ships new format (amount as string). Node accepts both. Old SDK clients keep working (send amount as number). New SDK clients send amount as string. After all clients upgrade, drop number support. - -**Problem — Fatal Flaw**: Hash mismatch. - -When a transaction is received with `amount: "100"` (string), the node must validate the signature. The signature was computed by the client as: - -``` -signature = sign(sha256(JSON.stringify({..., amount: "100", ...}))) -``` - -If the node deserializes the same bytes differently (parsing `"100"` as `100` before stringifying): - -``` -// In Node validation: -derivedHash = sha256(JSON.stringify({..., amount: 100, ...})) // Different! -// Signature verification fails -``` - -The transaction hash and signature become **incompatible with the new format**. The node cannot round-trip — it cannot verify the same transaction in two different formats. - -### 7.2 Why Dual-Format Fails - -**Byte-level commitment**: Signatures commit to the exact bytes of the serialized content. Changing serialization changes those bytes. There is no "accepting both formats" for hashing/signing — only one canonical form per block height. - -### 7.3 Why Hard Fork Works - -A hard fork sets a height N: -- **Height < N**: Node uses old serializer → verifies old-format signatures. -- **Height ≥ N**: Node uses new serializer → verifies new-format signatures. - -All nodes switch at height N in lockstep. No dual-format acceptance needed. No hash ambiguity. - -**Conclusion**: Dual-format window is **not viable for this migration**. Only the hard-fork approach works. - ---- - -## 8. Recommendation - -### **Hard Fork (RECOMMENDED)** - -**Why**: -1. **Block height is available everywhere** — no threading pain. -2. **Serialization has a single choke point** — clean integration. -3. **Database is format-agnostic** — no schema migration. -4. **Dual-format is infeasible** — signature/hash incompatibility. -5. **Moderate effort** — 2 person-days, not a major undertaking. -6. **Cleaner than network reset** — preserves historical state; users see continuous ledger. -7. **Upgradeable pattern** — once proven, can be extended for future forks. - -### **Sketch of Implementation** - -**File Structure**: -``` -src/libs/blockchain/forks/ -├── forkConfig.ts # Load fork heights from genesis -├── forkGates.ts # Helper functions like isForkActive(name, height) -└── serializerGate.ts # Conditional serialization based on block height - -src/utilities/ -└── sharedState.ts # Add forkHeights: Map -``` - -**Core Gate Function**: -```typescript -// src/libs/blockchain/forks/serializerGate.ts -import { FORK_HEIGHTS } from './forkConfig' -import Hashing from '@/libs/crypto/hashing' - -export async function serializeTransactionContent( - content: TransactionContent, - blockHeight?: number -): Promise { - const height = blockHeight ?? await Chain.getLastBlockNumber() - - if (height >= FORK_HEIGHTS.osDenomination) { - // Post-fork: amount is already string in content (or convert if needed) - return JSON.stringify(content) - } else { - // Pre-fork: ensure amount is number for backward compat - const legacyContent = { ...content } - if (typeof legacyContent.amount === 'string') { - legacyContent.amount = parseFloat(legacyContent.amount) - } - return JSON.stringify(legacyContent) - } -} - -export function isForkActive(forkName: string, blockHeight: number): boolean { - const height = FORK_HEIGHTS[forkName] - return height !== undefined && blockHeight >= height -} -``` - -**Genesis Config Extension**: -```json -{ - "forks": { - "osDenomination": { - "activationHeight": 12345 - } - } -} -``` - -**Call Sites (Example)**: -```typescript -// Before: -const hash = Hashing.sha256(JSON.stringify(tx.content)) - -// After: -const serialized = await serializeTransactionContent(tx.content, block?.number) -const hash = Hashing.sha256(serialized) -``` - -### **Not Recommended: Network Reset** - -A full network reset is **unnecessary and destructive**: -- Loses historical state and audit trail. -- Forces all users to resync genesis. -- More operationally complex than a coordinated fork. - -Only resort to this if: -- A critical consensus bug prevents soft fork. -- The chain has been compromised beyond recovery. - -Neither applies here. - ---- - -## 9.

The sender's balance was checked against breakdown.total but no deduction edits were emitted: the total fee was silently forgiven while the transaction was accepted. The justification comment in feeDistribution.ts claimed "the caller surfaces the rejection through applyGasFeeSeparation's failure path" — the actual code path was silent success. Fix: applyGasFeeSeparation now refuses the tx whenever breakdown.total > 0 AND generateFeeDistributionEdits returned 0 edits. Returns { ok: false, message: "fee distribution not primed — refusing to accept post-fork tx without fee collection" }. The ValidityData failure path signs that message into the response, matching the original intent. Zero-total txs still pass — the no-edits return is correct in that case. Tests: 3 new cases in tests/blockchain/applyGasFeeSeparation.test.ts: - rejects post-fork tx when feeDistribution is null - rejects post-fork tx when all percentages are 0 (init window) - accepts zero-total tx even when feeDistribution returns no edits beforeEach/afterEach were widened to restore feeDistribution to the SPEC defaults between cases so a sibling case can mutate it without leaking state to the PROD-balance-check block.

Each maps to a Mycelium task under epic E#11 (PR #817 review fixes). myc#102 — [G-1 + G-2] handleNativeOperations.ts (P1, critical) Mirror the applyGasFeeSeparation silent-fee-bypass guard onto the two post-fork TLSN branches (tlsn_request, tlsn_store). When generateSpecialOpsFeeEdits returns [] but the demanded fee is > 0 (requireFeeDistribution() null because feeDistribution was never primed OR every percentage is 0), the previous code spread the empty array onto `edits` and the TLSN operation proceeded without removing any tokens from the sender. Now both branches throw with a clear message so the tx is rejected at validation time. Adds one test per branch asserting the throw. myc#104 — [CR-3] handleError.ts (CodeRabbit minor) formatCauseChain was printing `${cause.name}: ${cause.message}` explicitly AND keeping that same line from Error.stack[0], producing duplicate header lines in the boot log. Skip the stack's first line when it begins with `${name}:`. Extracted the AggregateError sibling walk into formatAggregateSiblings to drop SonarCloud cognitive complexity from 16 to below the 15 threshold flagged in the same review. myc#103 — [CR-1 + CR-2] forking/*.md (CodeRabbit minor) Tagged every bare opening fence in REHEARSAL_RESULTS.md and RUNBOOK_FORK_ACTIVATION.md with `text` so markdownlint MD040 is satisfied.
