📝 Walkthrough

Walkthrough

The change gates finalized committee release on the accusation window, corrects failure attribution after committee expulsions, and moves reward and slash allocations to operator-held entitlements. It also documents fail-closed VectorX pointer rotation and adds integration coverage.

Changes

E3 settlement and committee lifecycle

Layer / File(s) Summary
Accusation-window committee release
packages/interfold-contracts/contracts/lib/RegistrySortitionLib.sol, packages/interfold-contracts/contracts/registry/CiphernodeRegistryOwnable.sol, packages/interfold-contracts/contracts/slashing/SlashingManager.sol, packages/interfold-contracts/test/E3Lifecycle/E3Integration.spec.ts
Finalized committees cannot release until the accusation deadline passes. Unfinalized committees remain releasable at terminal stage.
Failure attribution correction
packages/interfold-contracts/contracts/lib/InterfoldLifecycle.sol, packages/interfold-contracts/contracts/Interfold.sol, packages/interfold-contracts/contracts/slashing/SlashingManager.sol, packages/interfold-contracts/test/E3Lifecycle/E3Integration.spec.ts
Failed E3s can be reclassified to InsufficientCommitteeMembers before settlement.
Settlement documentation and ABI updates
agent/flow-trace/*, agent/INVARIANTS.md, packages/interfold-contracts/artifacts/contracts/interfaces/*, crates/evm/src/event_decoding/catalog.rs
Documentation, generated ABIs, and event decoding describe release gating and failure reclassification.

Operator-held reward and slash entitlements

Layer / File(s) Summary
Operator entitlement accounting
packages/interfold-contracts/contracts/E3RefundManager.sol, packages/interfold-contracts/contracts/interfaces/IE3RefundManager.sol
Success and slash allocations remain keyed by operator. Slash provenance is tracked per penalty target. Claim paths re-check expulsion state.
Reward distribution and claim routing
packages/interfold-contracts/contracts/lib/InterfoldPricing.sol, packages/interfold-contracts/contracts/Interfold.sol
Reward distribution transfers funds to E3RefundManager. Claim and pending-reward paths combine legacy balances with held rewards. Request payment now performs the token pull before recording balances.
Reward settlement validation
packages/interfold-contracts/test/E3Lifecycle/E3Integration.spec.ts, packages/interfold-contracts/test/Pricing/Pricing.spec.ts, agent/flow-trace/05_FAILURE_REFUND_SLASHING.md
Tests cover forfeiture, shared recipients, independent allocations, slash redistribution, custody, and aggregate RewardClaimed events.

Data availability operating constraints

Layer / File(s) Summary
VectorX pointer rotation and invariants
packages/interfold-contracts/contracts/verifiers/AvailVectorXDataAvailabilityVerifier.sol, packages/interfold-contracts/contracts/interfaces/IDataAvailabilityVerifier.sol, agent/INVARIANTS.md
Documentation records per-program provider binding, fail-closed pointer checks, and fixed deadlines.
Availability response documentation
agent/flow-trace/08_DATA_AVAILABILITY.md
The flow trace documents affected programs, unregisterE3Program containment, recovery, and repointing limitations.

Priority: ➖ Normal

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 4fcd6

A finalized committee can remain locked if its frozen slashing-manager address cannot answer the accusation-deadline query, preventing members from releasing collateral and claiming matured exits. Resolve this before merge.

767-767: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Validate the frozen slashing manager before accepting an E3 request.

requestCommittee can snapshot an unset address or an EOA as the E3 slashing manager. The no-return snapshot call can succeed. At Line 767, the later accusationSubmissionDeadline call requires return data and reverts. A finalized terminal E3 then cannot release its committee obligations, so bonded exits can remain blocked. Require a deployed slashing-manager contract when binding E3 dependencies.

- Around line 895-907: Update held-slash tracking so bucket keys are recorded
per holder independently of active committee membership. Add and maintain a
per-holder key list when buckets are created, then make _redistributeHeldSlash
and _clearHeldSlashProvenance iterate that list rather than only
getActiveCommitteeNodes results, preserving redistribution and cleanup for
expelled operators.
