Summary by CodeRabbit

  • New Features

    • Randomness timeouts now mark the system as degraded while keeping the configured provider available.
    • Added randomness health visibility, per-request balance reservations, and owner release of abandoned requests.
    • E3 programs must advertise required interfaces and match their assigned program; requests reject insufficient compute windows.
  • Bug Fixes

    • Failed-E3 refunds now wait for committee-affecting accusations and proposals to resolve, subject to a settlement cutoff.
    • Prevented unpublished data, zero content hashes, and invalid ciphertext publication from passing verification.
  • Documentation

    • Updated flow documentation and audit findings for the revised safeguards.

📝 Walkthrough

Walkthrough

The changes add zero-hash validation, advisory randomness expiry, pending-request VRF balance reservations, failed-E3 settlement gates, refund claim library wiring, and post-callback E3 validation before ciphertext publication.

Changes

Zenith audit fixes and settlement controls

Layer / File(s) Summary
Zero-hash validation
examples/CRISP/..., packages/interfold-contracts/contracts/verifiers/..., packages/interfold-contracts/test/DataAvailability/..., agent/flow-trace/...
Zero encrypted vote hashes and zero Avail content hashes are rejected. Tests and flow documentation record the checks.
Advisory randomness degradation
packages/interfold-contracts/contracts/lib/RegistrySortitionLib.sol, packages/interfold-contracts/contracts/randomness/..., packages/interfold-contracts/contracts/registry/..., packages/interfold-contracts/contracts/test/MockCiphernodeRegistry.sol, packages/interfold-contracts/test/Randomness/..., packages/interfold-contracts/test/Registry/..., packages/interfold-contracts/test/E3Lifecycle/..., agent/INVARIANTS.md, agent/flow-trace/..., templates/default/deployed_contracts.json
Expired responses retain the provider and set randomnessDegraded. VRF requests reserve balance per pending request and support owner release of abandoned requests.
Failed-E3 settlement and refund claims
packages/interfold-contracts/contracts/slashing/SlashingManager.sol, packages/interfold-contracts/contracts/interfaces/ISlashingManager.sol, packages/interfold-contracts/contracts/interfaces/IE3RefundManager.sol, packages/interfold-contracts/contracts/E3RefundManager.sol, packages/interfold-contracts/contracts/lib/RefundClaimLib.sol, packages/interfold-contracts/scripts/..., packages/interfold-contracts/ignition/modules/e3RefundManager.ts, packages/interfold-contracts/test/E3Lifecycle/..., packages/interfold-contracts/test/Slashing/..., packages/interfold-contracts/contracts/test/SlashingManagerProbeHarness.sol, packages/interfold-contracts/test/fixtures/system.ts, packages/interfold-contracts/artifacts/contracts/interfaces/ISlashingManager.sol/ISlashingManager.json, packages/interfold-contracts/artifacts/contracts/interfaces/IE3RefundManager.sol/IE3RefundManager.json, packages/interfold-contracts/artifacts/contracts/interfaces/IInterfold.sol/IInterfold.json, packages/interfold-contracts/artifacts/contracts/interfaces/ICiphernodeRegistry.sol/ICiphernodeRegistry.json, packages/interfold-contracts/artifacts/contracts/token/InterfoldTicketToken.sol/InterfoldTicketToken.json, templates/default/deployed_contracts.json
Failed-E3 settlement waits for accusation closure and committee-affecting proposals. Honest-node claim validation moves to RefundClaimLib, which is linked in deployment and upgrade paths.
Atomic ciphertext publication
packages/interfold-contracts/contracts/lib/InterfoldLifecycle.sol, packages/interfold-contracts/contracts/test/MockE3ProgramHarness.sol, packages/interfold-contracts/contracts/test/MockCiphernodeRegistry.sol, packages/interfold-contracts/test/Slashing/..., packages/interfold-contracts/contracts/test/SlashingManagerProbeHarness.sol, agent/INVARIANTS.md, agent/flow-trace/...
publishCiphertext rechecks the E3 stage and committee viability after verification. Tests cover verifier-triggered slashing and transaction rollback.

Merge Risk: 🟡 Moderate · up to ef446

This PR tightens committee and settlement handling, but the mock can accept provisional committees that production rejects, while related lifecycle inconsistencies remain. These mismatches can hide integration failures, so merge readiness is moderate pending correction.

Update the stale balance-check description.

954-958: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Correct the late-key failure attribution.

If the key is published at or before inputWindow[1], the round can reach KeyPublished and later produce requester-paid ComputeTimeout. If it arrives after inputWindow[1], onCommitteePublished rejects it, the stage remains CommitteeFinalized, and the round follows the committee-paid DKGTimeout path.

above the navigation table and restoring a three-cell header row to match its
three-cell delimiter row, so GitHub-flavored Markdown recognizes the table
correctly.

In `@agent/flow-trace/03_E3_REQUEST_AND_COMMITTEE.md`:
- Around line 684-688: Update the earlier admission-check description near the
minimumSubscriptionBalance discussion to state that each pending/unfulfilled
draw reserves one minimumSubscriptionBalance, with capacity calculated using
pending requests plus the new request. Remove the conflicting statement that
this value is not a reservation, while preserving the surrounding
ChainlinkVrfRandomnessProvider and abandonment behavior.

In `@packages/interfold-contracts/contracts/slashing/SlashingManager.sol`:
- Around line 363-380: The _committeeFinalized probe must fail closed when
canonicalCommitteeNodeAt is unavailable: treat only the explicit
CommitteeNotFinalized() error as “not finalized,” and revert or block settlement
for empty or unknown revert data. Update _committeeFinalized and preserve
settlementOpen/processE3Failure behavior so refunds cannot settle before
accusation and proposal obligations resolve.

In `@packages/interfold-contracts/scripts/deployAndSave/e3RefundManager.ts`:
- Around line 68-76: Update the deployment record created after deploying
E3RefundManager to include a top-level libraries field containing the deployed
RefundClaimLib address from refundClaimLib.getAddress(). Preserve the existing
library linking configuration in e3RefundManagerFactory.
