What and why

Bond owners need a simple way to make and register the ZKPassport proof that #2372 checks. This PR adds an identity section to the operator page of the dashboard. That page already sends the bonding transactions from the owner's wallet.

  • Shows the identity policy, the verifier settings, and the credential of the owner.
  • Creates a ZKPassport request with @zkpassport/sdk and shows it as a QR code or a phone link. The proof binds the owner and the chain. The document must be valid until a date that the owner picks.
  • Registers the proof from the owner's wallet. A Safe owner downloads a Safe Transaction Builder batch instead.
  • Lets the owner count right away. A button refreshes the operator, and under a required policy the Safe batch includes the refresh.
  • Stops a proof with another ZKPassport version, a proof that is too old, and a renewal that shortens the credential. It warns when the credential ends in the current 30-day window, because then the owner does not count.
  • Before a network has the registry, the page can still make a proof and download it as JSON for the fork test.

The SDK loads only when the owner starts a request. There are two new optional network settings: identityDeployBlock and identityRegistry.

Summary by CodeRabbit

  • New Features
    • Added bond-owner identity verification with ZKPassport, including identity-policy and credential status.
    • Operators can create proofs, register directly where available, or download proof files and Safe transaction batches.
    • Added warnings and status messages for credential validity, request capacity, and registration availability.
  • Documentation
    • Documented optional identity-policy scan start-block settings and the RPC log-retention requirement.

The operator guide gains a bond-owner identity panel. It reads the
identity policy from the latest IdentityPolicyUpdated log, the
verifier's fixed settings, and the owner's credential. It creates a
ZKPassport request bound to the owner and the chain, shows the QR code,
and builds the registration evidence from the expiry bound that the
proof committed to. An owner wallet registers directly; a Safe owner
downloads a Safe Transaction Builder batch. Before a deployment, the
panel makes a proof with the planned settings and offers only the
download, which the real-proof fork test replays.

The ZKPassport SDK and the QR code load only when an owner asks for a
proof.

Walkthrough

The dashboard adds bond-owner identity verification using ZKPassport. It reads identity policy, verifier configuration, and owner status; supports proof requests and downloads; and provides direct registration or Safe transaction batches. Network configuration includes an optional identity-policy scan start block.

Resolve the wrong-owner proof binding and configuration validation before merging. Identity status and registration controls also need consistent refresh and verifier checks to avoid misleading owners or preparing rejected registrations.

- The identity panel follows the bond owner, keyed by owner, so a
  wallet change keeps a finished proof and an old request's callbacks
  cannot reach another owner. A proof for another owner or chain is
  refused.
- The registration deadline is the earlier of the proof validity and
  the credential end, shown to the minute and checked against the
  clock, also before a Safe export.
- An EIP-7702 account registers directly; only contract wallets get
  the Safe batch.
- A registry without a verifier shows the credential and takes no
  registration; a cleared registry reads as no policy.
- Salted identifiers request strict FaceMatch, and a proof with
  another identifier type or OPRF key is refused.
- A renewal with an equal expiry is allowed, and capacity warnings
  apply only under a required policy, with the verifier's cap.

314-318: Trivial · Maintainability & Code Quality · Poor tradeoff

Add an interaction test for identity registration.

The current test uses renderToStaticMarkup, so it checks only static markup. Removing onClick={() => onRegister(bundle)} would leave the assertions passing. No other test exercises this button interaction.

Add a DOM-based test that clicks the button and asserts that onRegister receives bundle.

- Around line 132-133: Validate DEPLOY_BLOCK and IDENTITY_DEPLOY_BLOCK
environment overrides during Vite configuration, rejecting non-integer values so
invalid settings fail the build before chain.ts loads and the dashboard shell
renders.

Review comments at @packages/interfold-dashboard/src/lib/identity.ts:
- Around line 100-106: Bound the identity policy lookup around getLogsChunked
and policyScanStart so it does not scan sequentially from IDENTITY_DEPLOY_BLOCK
to the current head; use a bounded query or reuse a cached latest policy result,
while preserving the latest applicable policy for identity status and
registration controls.
- Around line 298-303: Update parseDateInput to preserve years from 0000 through
0099 instead of allowing Date.UTC to remap them to 1900 through 1999. Construct
the date and set its UTC year, month, and day with setUTCFullYear, then retain
the existing rollover validation and timestamp return behavior.

Review comments at @packages/interfold-dashboard/src/Operator.tsx:
- Around line 1522-1523: Update identityService so the derived faceMatch value
is true when either verifier.faceMatchRequired is true or verifier.nullifierType
is 1. Keep the existing behavior for other verifier settings.
- Around line 1435-1450: Update the IdentityPanel loading effect that calls
fetchIdentityPolicy and fetchVerifierConfig so governance policy changes trigger
a refresh without a page reload. Refetch the policy on a timer or in response to
IdentityPolicyUpdated logs, and reload the verifier when the policy registry
changes so registration and Safe batch actions use current configuration.
- Around line 1851-1857: Update the verifier validation in the
`versionMatches`/`keyMatches` flow and the `blocked` condition to also compare
the stored proof’s domain and scope with the reloaded verifier and verify the
proof satisfies its FaceMatch requirement. Add a corresponding warning note for
each failed check so the register and Safe download buttons remain disabled
until the proof matches the verifier.
- Around line 1453-1467: Update the clock effect and loaded-state derivation in
Operator so verification status reflects credential expiry while the panel
remains mounted. Run the clock interval regardless of request phase, and derive
identity.verifiedNow from the current clock and identity.expiresAt whenever the
clock advances, preserving the existing behavior for other loaded fields.
- Around line 234-238: Update the identity-switch handling in useBonding so
status is exposed only when it belongs to the current identity; return null for
stale status during the switch. This prevents Operator’s ownerOf state from
capturing the previous operator’s bond owner while preserving status once the
new identity has loaded.
- Around line 1486-1488: Tag account results with the registry used by
fetchOwnerAccount in the IdentityPanel flow, and update the account state when
the read completes to retain that registry. Update the loaded account selection
to require both owner and current policy registry to match before using the
result.

- useBonding returns no status in the render that switches operators, so
  the identity panel never keeps the previous operator's bond owner.
- The identity panel keeps each owner read with its registry, follows the
  clock in every phase, and shows a credential as expired after its end.
- A salted identifier always requests strict FaceMatch, so the panel and
  the downloaded proof say so.
- parseDateInput keeps years below 100.
- The build stops on a DEPLOY_BLOCK or IDENTITY_DEPLOY_BLOCK override that
  is not a whole number.

Review handled in f52ab84.

Fixed:

  • Block overrides: the build stops on a DEPLOY_BLOCK or IDENTITY_DEPLOY_BLOCK override that is not a whole number, on every network.
  • useBonding returns no status in the render that switches operators, so the panel never keeps the previous bond owner.
  • Each owner read keeps its registry. The clock runs in every phase, and a credential shows as expired after its end.
  • A salted identifier sets faceMatch, so the notice, the request, and the downloaded proof agree.
  • parseDateInput keeps years below 100.

Kept, with reasons in the threads: the policy scan bound, polling for policy changes, and domain or scope checks on a stored proof.

Nitpick (click test for register): skipped. The package tests run in Node with renderToStaticMarkup and no DOM, so a click test would add a DOM library for one button.

Checks: typecheck, 29 tests, vite build, and a build with VITE_MAINNET_IDENTITY_DEPLOY_BLOCK=26300000.0 (stops as expected).

# Conflicts:
#	packages/interfold-dashboard/src/lib/networks.ts
Public RPCs keep about a day of logs, and the identity panel found the
registry only through the latest IdentityPolicyUpdated log. A day after
the upgrade, owners lost the registration path on such an RPC.

- New network setting identityRegistry (VITE_<NETWORK>_IDENTITY_REGISTRY_ADDRESS),
  the OwnerIdentityRegistry proxy, set after the upgrade.
- The policy log still wins when it can be read. Without one in reach,
  the configured registry opens registration and the policy shows as
  unknown.
- README and .env.example: set both identity values and a log-capable
  RPC on the day of the upgrade.
A registration verifies the owner at once, but owner capacity counts it
only after a status refresh of one of its operators. Nodes refresh at
each window start, so a new owner could wait up to 30 days.

- The Safe batch registers and then refreshes the page's operator when
  it is registered (one atomic batch).
- A wallet owner gets "Count the owner now" after registering, when the
  policy is required.
- Tests decode the refresh call and render both paths.
