PLAN** — Decompose into subtasks.

Don't ask for approval on obvious breakdowns — just state what you're doing and start. Ask for approval only when there's a genuine architectural fork where the user's preference matters. + +**3.

VERIFY** — Every output gets reviewed before integration. +- Junior output: inspect by glance. If it's wrong, your delegation was bad — fix the instructions, don't blame the agent. +- Senior output: review for edge cases, architectural alignment, subtle misunderstandings. Ask targeted questions before rejecting. + +**5. INTEGRATE** — Assembly is always your job. Never delegate integration.

Delegate. +- **Vague delegation** — "Handle this" is not a task. If you can't be specific, you don't understand the problem yet. +- **Over-delegation** — Don't write a 10-line TASK block for a 3-line change. Use judgment. +- **Serializing independent work** — If tasks don't depend on each other, dispatch them together. +- **Blind trust** — Always verify. Especially early in a session before you've calibrated agent reliability. +- **Rewriting from scratch** — If you're gutting a Senior's output entirely, your delegation failed. Fix the delegation next time. + +### Interacting With The User + +- **You are the interface.** The user talks to you, not to your agents. Shield them from delegation mechanics unless they ask. +- **Be direct.** State what you're doing, what's done, what needs their input. No padding. +- **Escalate decisions, not problems.** Don't say "the Senior had trouble with X." Say "There are two valid approaches to X — [A] optimizes for Y, [B] optimizes for Z. Which do you prefer?" +- **All existing user preferences and project conventions still apply.** Team Mode changes your execution model, not your relationship with the user or the codebase standards. + +--- + +## Edge Cases + +**User gives a trivial task while Team Mode is on:** +Just do it. Don't force-decompose a one-liner into a delegation plan. Team Mode means you *can* delegate, not that you *must*. + +**User asks you to implement something directly:** +Do it. The user outranks the process. If they say "just write this," write it. + +**Ambiguity about whether something is a Junior/Senior/Lead task:** +Default up. It's cheaper to over-qualify a task than to redo it after a bad delegation. + +**A delegated task fails repeatedly:** +Escalate it one tier. If Junior can't do it, re-scope for Senior. If Senior can't, do it yourself.

Delta Determinism (Critical) + +**Risk**: If two honest nodes produce different state deltas for the same transaction, they'll disagree and flag it as PROBLEMATIC — false positives degrade throughput. + +**Causes of non-determinism**: +- Floating point arithmetic in fee calculations +- Timestamp-dependent logic in execution +- Database read order differences +- JSON serialization key ordering + +**Mitigation**: +- Use `BigInt` for all numeric operations (already the case for balances) +- Delta hashing must use canonical JSON serialization (sorted keys) +- Speculative execution must be pure — no side effects, no I/O +- Test delta determinism as a first-class property (Phase 1 acceptance criteria) + +**Existing advantage**: GCR edits are already deterministic (SDK generates them from tx content only) + +--- + +## 2. Network Latency in Delta Exchange + +**Risk**: 1–2s forge cycle is tight. If delta exchange takes >500ms, there's limited time for comparison and promotion. + +**Mitigation**: +- Exchange delta *hashes* (32 bytes each), not full deltas +- Use OmniProtocol binary encoding for minimal overhead +- Allow configurable forge interval (start at 2s, optimize to 1s) +- If a member doesn't respond in time, continue with available responses +- Threshold is 7/10 — missing 1–2 responses is tolerable + +--- + +## 3. Race Condition: Tx Arrives During Block Compilation + +**Risk**: A transaction arrives and gets PRE-APPROVED during the 10s block compilation window. Does it go in the current block or next? + +**Design decision**: Cut-off. Any tx not PRE-APPROVED before block compilation starts goes into the next block. The Continuous Forge stops during compilation (Phase 3, Task 4). + +**Implementation**: Use a mutex/flag. When block compilation starts, the forge loop yields. New txs go to mempool for next round. + +--- + +## 4. Secretary vs Leaderless Trade-off + +**Risk**: Petri is described as leaderless, but coordinating the 10s block boundary still needs some synchronization. + +**Design decision**: Use the block timestamp as the coordinator. All nodes independently know when the 10s boundary is because they share the same block history and averaged timestamps. No leader needed for timing — just clock sync (already exists via `averageTimestamps.ts`). + +**For Continuous Forge**: Each node runs the loop independently. Delta exchange is peer-to-peer within the shard. No single point of failure. + +--- + +## 5. Multi-Shard Address Routing (Future) + +**Risk**: The pitch describes address-space-based shard assignment. With a single shard (testnet), this is trivial. With multiple shards, cross-shard transactions become complex. + +**Design decision for now**: Single-shard implementation. All addresses map to one shard. The `ShardMapper` interface is designed for extensibility but only implements single-shard. + +**Future considerations**: +- Cross-shard atomic transactions need a 2-phase commit protocol +- Address-space partitioning needs to handle hot addresses (popular contracts) +- Rebalancing shards when load is uneven + +--- + +## 6. L2PS Interaction + +**Risk**: L2PS has its own mempool and execution model. How does it interact with Petri's classification? + +**Design decision**: L2PS transactions are classified as TO-APPROVE (they produce state changes). L2PS proofs are applied at the 10s block boundary (same as current). The Continuous Forge handles L2PS transaction deltas like any other state-changing tx. + +**No change needed** to `L2PSMempool`, `L2PSTransactionExecutor`, or `L2PSConsensus` core logic. Only the timing of `applyPendingProofs()` changes slightly. + +--- + +## 7. Backward Compatibility During Migration + +**Risk**: During migration, some nodes run PoRBFT v2 and some run Petri. They must coexist. + +**Mitigation**: +- Feature flag controls which consensus routine runs +- Both produce blocks in the same format (same `Block` class, same `Chain.insertBlock()`) +- Shard selection is identical (same CVSA, same Alea PRNG) +- Migration is coordinated: all validators switch at a specific block number +- Fallback: if Petri fails, nodes can restart with PoRBFT v2 flag + +--- + +## 8. Byzantine Behavior in Continuous Forge + +**Risk**: A Byzantine node could deliberately return wrong deltas every round, causing transactions to be flagged PROBLEMATIC. + +**Mitigation**: +- The 7/10 threshold means up to 3 Byzantine nodes can't prevent agreement +- If 7+ honest nodes agree, the tx is promoted regardless of 3 bad actors +- A node consistently producing wrong deltas can be detected and reputation-penalized +- PROBLEMATIC txs still go through BFT arbitration — they're not lost, just delayed + +--- + +## 9. Mempool Size During Continuous Forge + +**Risk**: With 1–2s sync cycles, the mempool grows continuously. At high TPS, memory and DB pressure could be significant. + +**Mitigation**: +- Existing mempool is DB-backed (TypeORM/PostgreSQL) — handles scale +- PRE-APPROVED txs are cleaned from mempool after block inclusion +- PROBLEMATIC txs have a TTL — rejected after N forge rounds without resolution +- Mempool already has duplicate detection (hash-based) + +--- + +## 10. Testing Strategy + +**Critical test scenarios**: + +1. **Happy path**: 10 honest nodes, no conflicts → all txs PRE-APPROVED in <2s +2. **Conflict path**: 2 txs spending same balance → one PROBLEMATIC → BFT resolves +3. **Byzantine minority**: 3/10 nodes return bad deltas → 7/10 still agree → system works +4. **Byzantine threshold**: 4/10 nodes collude → system detects, flags txs as PROBLEMATIC +5. **Network partition**: 2 members temporarily unreachable → forge continues with 8 +6. **Clock skew**: Members have ±500ms clock difference → forge still converges +7. **Load test**: Sustained 5000 TPS → soft finality <2s, hard finality <12s +8. **Liveness**: PROBLEMATIC txs never stall block production +9. **Rollback**: Feature flag off → PoRBFT v2 resumes cleanly + +--- + +## 11.

Petri Consensus treats each shard as a biological culture — autonomous, self-verifying, and deterministically orchestrated. + +--- + +## EXECUTIVE SUMMARY + +### The Problem + +Current blockchain consensus mechanisms force a fundamental trade-off: either every validator processes every transaction (limiting throughput), or the network fragments into isolated execution environments (breaking composability). BFT-based systems achieve safety but at the cost of per-transaction coordination overhead that grows with validator count. The result is an industry stuck between ~1,000 TPS with full security or opaque scaling solutions that reintroduce trust assumptions. + +### The Insight + +Most transactions in a well-functioning blockchain do not actually conflict. BFT consensus is essential for safety, but using it as the primary execution engine is wasteful — it should be an exception handler, not the main loop. If nodes can independently execute non-conflicting transactions and only invoke heavyweight consensus when disagreements arise, throughput scales dramatically while maintaining full Byzantine fault tolerance. + +### Petri Consensus + +Petri Consensus implements this insight through a three-phase architecture: instant cryptographic validation at the RPC layer, continuous-forge execution within rotating 10-node shards that sync and verify state deltas every 1–2 seconds, and BFT arbitration only for conflicting transactions at the 10-second block boundary. The result: the vast majority of transactions reach finality without ever triggering BFT, while the small minority of conflicts are resolved with full Byzantine safety guarantees. + +| Metric | Value | +|--------|-------| +| Target TPS per shard (testnet milestone) | 5,000–15,000 | +| Soft finality (pre-approval) | 1–2s | +| Hard finality (block confirmation) | 10s | + +--- + +## PROTOCOL MECHANISM + +Petri Consensus operates in three temporal phases, each optimized for its specific role in the transaction lifecycle. + +### PHASE 1 — INSTANT VALIDATION + +**01 Transaction Submission** +Client submits a signed transaction to any RPC endpoint in the network. The RPC node is stateless and serves as a cryptographic gatekeeper. + +**02 Cryptographic Validation & Routing** +The RPC node verifies the transaction signature, checks format validity, and deterministically routes to two members of the assigned shard. Shard assignment is derived from the transaction's address space. + +**03 Shard-Level Verification & Classification** +Each receiving shard member independently verifies cryptography and classifies the transaction: read-only / non-state-changing transactions are immediately marked as PRE-APPROVED. State-changing transactions are executed speculatively, producing a state delta, and marked as TO-APPROVE. + +### PHASE 2 — CONTINUOUS FORGE (1–2 second cycle) + +**04 Mempool Synchronization** +Every 1–2 seconds, shard members synchronize their local mempools using the Continuous-Forge merge algorithm. This produces a deterministic ordering of all pending transactions across the shard. + +**05 Parallel Re-execution & Delta Verification** +Each shard member re-executes all TO-APPROVE transactions against the merged, ordered mempool and produces a state delta. Deltas are compared across the shard. If ≥7/10 members agree (BFT threshold: ⌊2n/3⌋ + 1), the transaction is promoted to PRE-APPROVED. + +**06 Conflict Detection** +Transactions that fail to reach delta agreement are flagged as PROBLEMATIC. These are quarantined from the happy path and deferred to Phase 3 for BFT arbitration. + +### PHASE 3 — BLOCK FINALIZATION (10-second boundary) + +**07 Block Compilation** +At the 10-second mark, shard members compile all PRE-APPROVED transactions into a candidate block. Transaction ordering is deterministic, derived from the merge algorithm's output. This is the happy path — for most blocks, this step completes without requiring any additional consensus overhead. + +**08 BFT Arbitration (Exception Path)** +PROBLEMATIC transactions enter a standard BFT round (⌊2n/3⌋ + 1 = 7/10 agreement). If consensus is reached, the transaction is included in the block. If not, the transaction is rejected — the chain never stalls. This fail-safe design means BFT latency only affects conflicting transactions, not overall throughput. + +--- + +## SHARD ROTATION MECHANISM + +Shard composition is deterministic, rotating, and democratic. Every block, shard membership is recalculated using a PRNG seeded with the hash of the previous block. This guarantees: + +- **Unpredictability** — No party can predict shard composition more than one block ahead, preventing targeted attacks +- **Determinism** — Every node independently computes identical shard assignments from the same block hash — no coordination required +- **Democratic Rotation** — Over time, every validator participates in every shard with uniform probability, preventing power concentration +- **Verifiability** — Any observer can verify that shard assignments are correct by rerunning the PRNG with the public block hash + +**Shard size:** 10 validators — chosen to balance BFT quorum efficiency (7/10 threshold), network overhead (manageable sync every 1–2s), and security (tolerates up to 3 Byzantine actors per shard per block). + +--- + +## TRANSACTION LIFECYCLE + +``` +CLIENT → RPC → SHARD (Verify) → MEMPOOL SYNC → [STATE DELTA] + ↓ + pre-approved → BLOCK COMPILE → FINAL BLOCK + ↓ + problematic → BFT (if needed) → [rejected or included] +``` + +**Timeline:** +- ~instant: Client to Shard verification +- 1-2s sync: Mempool synchronization and state delta verification +- 10s block: Block compilation and finalization + +*Happy path (majority of transactions): solid lines* +*Exception handling for conflicting state: dashed lines* + +--- + +## SECURITY PROPERTIES + +### Byzantine Fault Tolerance +Each shard tolerates up to 3 malicious validators (f < n/3 where n = 10). Both the continuous-forge state verification and the BFT arbitration phase use the same ⌊2n/3⌋ + 1 threshold, ensuring consistent safety guarantees. + +### Anti-Collusion via Rotation +Deterministic shard rotation makes it economically infeasible to coordinate attacks: an adversary would need to control ≥4 of 10 randomly selected validators every block, with assignments changing every 10 seconds. + +### Liveness Guarantee +The chain never stalls. Conflicting transactions are rejected rather than retried, ensuring block production continues on schedule regardless of Byzantine behavior within the shard. + +### Dual Finality +Soft finality at 1–2 seconds (pre-approval) enables responsive UX for applications, while hard finality at 10 seconds (block inclusion) provides settlement-grade security. + +--- + +## PERFORMANCE TARGETS + +Performance projections are based on 10-node shard architecture with 1–2 second sync cycles and 10-second block times. These are conservative testnet targets — mainnet optimizations (parallel shard execution, adaptive block sizing, pipelined verification) can significantly increase throughput. + +| Metric | Target | +|--------|--------| +| TPS per shard (testnet target) | 5,000–15,000 | +| Horizontal scaling with additional shards | 10x+ | + +--- + +## COMPETITIVE LANDSCAPE + +| Protocol | Consensus | TPS | Finality | BFT Role | Validator Load | +|----------|-----------|-----|----------|----------|----------------| +| Ethereum 2.0 | Gasper (LMD+Casper) | ~30–100 | ~12 min (epoch) | Primary engine | Full chain processing | +| Solana | Tower BFT + PoH | ~4,000 (theoretical 65k) | ~0.4s (slot) | Primary engine | Full chain processing | +| Sui / Aptos | Narwhal & Bullshark/Tusk | ~5,000–10,000 | ~2–3s | DAG-based ordering | Object-level parallel | +| Cosmos Zones | Tendermint BFT | ~1,000 per zone | ~6s | Primary engine | Per-zone processing | +| **Demos (Petri)** | **Continuous-Forge + BFT** | **5,000–15,000 per shard** | **1–2s soft / 10s hard** | **Exception handler only** | **Shard-scoped (10 nodes)** | + +**Demos' key differentiator:** BFT as exception handler, not primary engine.

If the result is `TO_APPROVE`, it calls `executeSpeculatively` which runs GCR routines in simulate mode (no DB mutation), serializes edits via `canonicalJson`, and hashes them with `Hashing.sha256` to produce a deterministic `deltaHash`. The classification and delta hash are then persisted to the mempool entity via `Mempool.updateClassification`. +- **Feature flag gate:** The entire Phase 1 pipeline in `endpointValidation.ts` is gated behind `getSharedState.petriConsensus`. When the flag is `false` (default), no classification or speculative execution occurs. +- **Mempool columns:** `classification` and `delta_hash` are nullable to maintain backward compatibility — existing transactions without classification continue to work normally.

If the result is `TO_APPROVE`, it calls `executeSpeculatively` which runs GCR routines in simulate mode (no DB mutation), serializes edits via `canonicalJson`, and hashes them with `Hashing.sha256` to produce a deterministic `deltaHash`. The classification and delta hash are then persisted to the mempool entity via `Mempool.updateClassification`. -- **Feature flag gate:** The entire Phase 1 pipeline in `endpointValidation.ts` is gated behind `getSharedState.petriConsensus`. When the flag is `false` (default), no classification or speculative execution occurs. +- **Feature flag gate:** The entire Petri pipeline (Phase 1 classification in `endpointValidation.ts` and Phase 2 forge loop) is gated behind `getSharedState.petriConsensus`. When the flag is `false` (default), no classification, speculative execution, or forge activity occurs. - **Mempool columns:** `classification` and `delta_hash` are nullable to maintain backward compatibility — existing transactions without classification continue to work normally. +- **Phase 2 forge loop:** `petriConsensusRoutine(shard)` creates a `ContinuousForge`, registers it as a global singleton via `setPetriForgeInstance`, and starts the 2-second interval loop. Each `runForgeRound` syncs mempools, speculatively executes TO_APPROVE transactions, exchanges delta hashes with shard peers via `petri_exchangeDeltas` RPC, feeds results into `DeltaAgreementTracker`, and promotes or flags transactions based on agreement threshold / TTL expiry. +- **RPC bridge:** The `petri_exchangeDeltas` handler in `manageConsensusRoutines.ts` reads the global `petriForgeInstance` singleton to call `getCurrentDeltas()`, returning local delta hashes to the requesting peer. This decouples the RPC layer from the forge loop lifecycle. +- **Phase 3 placeholder:** `petriConsensusRoutine` includes a `// REVIEW:` comment noting that Phase 3 will add block finalization logic.

Each `runForgeRound` syncs mempools, speculatively executes TO_APPROVE transactions, exchanges delta hashes with shard peers via `petri_exchangeDeltas` RPC, feeds results into `DeltaAgreementTracker`, and promotes or flags transactions based on agreement threshold / TTL expiry. - **RPC bridge:** The `petri_exchangeDeltas` handler in `manageConsensusRoutines.ts` reads the global `petriForgeInstance` singleton to call `getCurrentDeltas()`, returning local delta hashes to the requesting peer. This decouples the RPC layer from the forge loop lifecycle. -- **Phase 3 placeholder:** `petriConsensusRoutine` includes a `// REVIEW:` comment noting that Phase 3 will add block finalization logic. +- **Phase 3 block lifecycle:** `petriConsensusRoutine` now implements the full block lifecycle: (1) start forge, (2) sleep for `blockIntervalMs` (default 10s) while txs accumulate, (3) pause forge, (4) arbitrate PROBLEMATIC txs via BFT, (5) compile block from PRE_APPROVED + resolved txs, (6) finalize block (broadcast hash → validate → insert → broadcast block), (7) clean rejected txs from mempool, (8) reset and resume forge for the next block cycle. +- **Reused PoRBFT v2 infrastructure:** Phase 3 reuses `createBlock()`, `orderTransactions()`, `broadcastBlockHash()`, `getCommonValidatorSeed()`, and `getShard()` from `src/libs/consensus/v2/routines/`, plus `insertBlock()` from `src/libs/blockchain/chainBlocks.ts` and `BroadcastManager.broadcastNewBlock()` from `src/libs/communications/broadcastManager.ts`. This avoids duplicating battle-tested block assembly and broadcast logic. +- **Consensus dispatch switching:** Both `mainLoop.ts` and `manageConsensusRoutines.ts` now check the `petriConsensus` flag to route consensus operations to either the Petri pipeline or the existing PoRBFTv2 routine.

This avoids duplicating battle-tested block assembly and broadcast logic. - **Consensus dispatch switching:** Both `mainLoop.ts` and `manageConsensusRoutines.ts` now check the `petriConsensus` flag to route consensus operations to either the Petri pipeline or the existing PoRBFTv2 routine. +- **Phase 4 RPC routing refactor:** `endpointExecution.ts` now checks the `petriConsensus` flag early. When enabled, it calls `petriRelay(validityData)` and returns immediately, bypassing the validator check and existing DTR flow entirely. When disabled, the existing DTR flow is unchanged. +- **Shard mapping:** `shardMapper.ts` provides `getShardForAddress()` which currently returns `'default'` for single-shard testnet. This is the extension point for future multi-shard support. +- **Deterministic member selection:** `petriRouter.selectMembers()` uses Alea PRNG seeded with the transaction hash to deterministically select `membersPerTx` (default 2) shard members for relay. This ensures any node given the same txHash and shard membership list will select the same members. +- **Relay transport:** Selected members receive the validated transaction via `peer.longCall()` with `method: "nodeCall"` and `message: "RELAY_TX"`, reusing the existing node call infrastructure.

This is the extension point for future multi-shard support. - **Deterministic member selection:** `petriRouter.selectMembers()` uses Alea PRNG seeded with the transaction hash to deterministically select `membersPerTx` (default 2) shard members for relay. This ensures any node given the same txHash and shard membership list will select the same members. - **Relay transport:** Selected members receive the validated transaction via `peer.longCall()` with `method: "nodeCall"` and `message: "RELAY_TX"`, reusing the existing node call infrastructure. +- **Dual finality model (P5):** Petri consensus introduces two finality tiers. **Soft finality** (~2s) occurs when a transaction reaches `PRE_APPROVED` status via forge delta agreement — the `soft_finality_at` timestamp is recorded on both `MempoolTx` and `Transactions` entities. **Hard finality** (~12s) occurs when the transaction is confirmed in a finalized block on chain, determined by block inclusion lookup. +- **`soft_finality_at` column (P5):** Added to both `MempoolTx` (mempool entity) and `Transactions` (chain entity) as a nullable datetime. On `MempoolTx`, it is set when the forge promotes a tx to `PRE_APPROVED` via `updateClassification`. On `Transactions`, the value is preserved from the mempool record when the tx is inserted into a block. +- **Transaction finality service (P5):** `getTransactionFinality(txHash)` in `finality/transactionFinality.ts` implements a chain-first lookup strategy: (1) check the `Transactions` entity — if found, the tx is `"confirmed"` with hard finality from the block timestamp and optional soft finality from `soft_finality_at`; (2) check `MempoolTx` — if found, the tx is `"pending"` with classification and optional soft finality; (3) if neither, return `"unknown"`. +- **Finality RPC endpoint (P5):** The `getTransactionFinality` method is exposed as an RPC endpoint in `rpcDispatch.ts`, allowing clients to query the finality status of any transaction by hash.

If the result is `TO_APPROVE`, it calls `executeSpeculatively` which runs GCR routines in simulate mode (no DB mutation), serializes edits via `canonicalJson`, and hashes them with `Hashing.sha256` to produce a deterministic `deltaHash`. The classification and delta hash are then persisted to the mempool entity via `Mempool.updateClassification`.

On `Transactions`, the value is preserved from the mempool record when the tx is inserted into a block. - **Transaction finality service (P5):** `getTransactionFinality(txHash)` in `finality/transactionFinality.ts` implements a chain-first lookup strategy: (1) check the `Transactions` entity — if found, the tx is `"confirmed"` with hard finality from the block timestamp and optional soft finality from `soft_finality_at`; (2) check `MempoolTx` — if found, the tx is `"pending"` with classification and optional soft finality; (3) if neither, return `"unknown"`. - **Finality RPC endpoint (P5):** The `getTransactionFinality` method is exposed as an RPC endpoint in `rpcDispatch.ts`, allowing clients to query the finality status of any transaction by hash. +- **Secretary deprecation (P7):** All secretary-era consensus code has been marked with `@deprecated` JSDoc markers. No code was deleted — the entire Secretary infrastructure is preserved intact to allow PoRBFT v2 fallback if `petriConsensus` is set to `false`. The deprecated surface includes: `SecretaryManager` class (1018 lines in `secretaryManager.ts`), four RPC handlers in `manageConsensusRoutines.ts` (`setValidatorPhase`, `greenlight`, `getValidatorPhase`, `getBlockTimestamp`), four OmniProtocol consensus opcodes (0x35–0x38) in `consensus.ts`, and `ValidationPhase` types in `validationStatusTypes.ts`. +- **Deferred deletion (Task #119):** Full removal of deprecated Secretary code and the `petriConsensus` feature flag is deferred to post-testnet validation. Once Petri consensus is proven stable on testnet, Task #119 will delete all deprecated code and make Petri the sole consensus path.

Key Architectural Insight + +The GCR refactor is a **performance-critical change**: instead of N database round-trips per edit, entities are batch-loaded into a `Map`, modified in-memory, and saved once at the end. This directly benefits Petri's continuous forge loop where many TXs are processed per round. The `speculativeExecutor` fix ensures Petri's simulation path also gets this performance improvement. + +The TX count inversion bug (`74a4a6e`) was in shared code (`mempool_v2.ts`, `PoRBFT.ts`). Since Petri builds on these same code paths, this fix prevents incorrect transaction classification that could have caused consensus disagreements between nodes. diff --git a/src/libs/consensus/petri/execution/speculativeExecutor.ts b/src/libs/consensus/petri/execution/speculativeExecutor.ts index 0c4c0674..17009b4c 100644 --- a/src/libs/consensus/petri/execution/speculativeExecutor.ts +++ b/src/libs/consensus/petri/execution/speculativeExecutor.ts @@ -10,15 +10,10 @@ */ import type { Transaction, GCREdit } from "@kynesyslabs/demosdk/types" -import type { Repository } from "typeorm" import type { StateDelta } from "@/libs/consensus/petri/types/stateDelta" import { canonicalJson } from "@/libs/consensus/petri/utils/canonicalJson" import Hashing from "@/libs/crypto/hashing" -import Datasource from "@/model/datasource" -import { GCRMain } from "@/model/entities/GCRv2/GCR_Main" -import GCRBalanceRoutines from "@/libs/blockchain/gcr/gcr_routines/GCRBalanceRoutines" -import GCRNonceRoutines from "@/libs/blockchain/gcr/gcr_routines/GCRNonceRoutines" -import GCRIdentityRoutines from "@/libs/blockchain/gcr/gcr_routines/GCRIdentityRoutines" +import HandleGCR from "@/libs/blockchain/gcr/handleGCR" import log from "@/utilities/logger" import Chain from "@/libs/blockchain/chain" @@ -43,53 +38,22 @@ export async function executeSpeculatively( tx: Transaction, gcrEdits: GCREdit[], ): Promise { - const db = await Datasource.getInstance() - const gcrMainRepo: Repository = db - .getDataSource() - .getRepository(GCRMain) - - // REVIEW: Execute each GCR edit in simulation mode (simulate=true) - // This runs the full logic but skips the database save - for (const edit of gcrEdits) { - let result: { success: boolean; message: string } - - switch (edit.type) { - case "balance": - result = await GCRBalanceRoutines.apply( - edit, - gcrMainRepo, - true, // simulate — no DB write - ) - break - case "nonce": - result = await GCRNonceRoutines.apply( - edit, - gcrMainRepo, - true, - ) - break - case "identity": - result = await GCRIdentityRoutines.apply( - edit, - gcrMainRepo, - true, - ) - break - default: - // For other GCR edit types (storage, tls, etc.), we still produce a delta - // but skip simulation — the edit presence itself is the state change signal - result = { success: true, message: "passthrough" } - break - } + // Use the new in-memory GCR pattern: batch-load accounts, then apply in simulation mode + const accounts = await HandleGCR.prepareAccounts([tx]) + const applyResult = await HandleGCR.applyTransaction( + accounts, + tx, + false, // not a rollback + true, // simulate — no DB write + ) - if (!result.success) { - log.warn( - `[PetriSpecExec] Simulation failed for TX ${tx.hash}, edit type=${edit.type}: ${result.message}`, - ) - return { - success: false, - error: `Simulation failed: ${result.message}`, - } + if (!applyResult.success) { + log.warn( + `[PetriSpecExec] Simulation failed for TX ${tx.hash}: ${applyResult.message}`, + ) + return { + success: false, + error: `Simulation failed: ${applyResult.message}`, } } From aa7663e395dc72ba3f927a2aa6b3175edc03c89d Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 2 Apr 2026 16:09:34 +0000 Subject: [PATCH 65/65] fix: update omni gcr handler to new in-memory GCR API + gitignore merge reports MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit omniprotocol/handlers/gcr.ts was passing Repository to GCRIdentityRoutines.apply() which now expects a GCRMain entity.
