📝 Walkthrough

Walkthrough

The CLI now waits for asynchronous election-event imports and exposes voter imports without client-side hashing. A telephone IVR load-test script automates election setup. Generated GraphQL schemas and types expose profile, deletion, ballot-publication, increment, and blank-ballot result fields.

Changes

Telephone load-test setup

Layer / File(s) Summary
Election-event import task polling
packages/step-cli/src/graphql/import_election_event.graphql, packages/step-cli/src/commands/import_election_event.rs
The import mutation returns task execution data. The CLI polls for completion, failure, status errors, and timeout before returning the election-event ID.
Voter import command and wiring
packages/step-cli/src/commands/import_voters.rs, packages/step-cli/src/graphql/import_users.graphql, packages/step-cli/src/commands/mod.rs, packages/step-cli/src/main.rs
The CLI adds voter upload, GraphQL import execution, and the ImportVoters subcommand. Client-side SHA-256 computation is removed.
Telephone load-test setup workflow
packages/step-cli/scripts/setup-telephone-load-test.sh
The script validates inputs, creates election data and numeric-password voters, imports voters, completes trustee operations, publishes the event, opens TELEPHONE voting, and writes output files.
Generated GraphQL contract updates
packages/*/graphql.schema.json, packages/*/src/gql/graphql.ts, packages/ballot-verifier/src/gql/gql.ts
Generated schemas and types add task execution details, user-profile configuration, expanded user deletion filters, election-area increments, blank-ballot result metrics, and published ballot-publication identifiers. The admin portal removes undefined from InputMaybe<T>.
Metadata formatting
hasura/metadata/databases/backend-db/tables/sequent_backend_ballot_publication.yaml
The voter permission comment uses a folded YAML block scalar. Permission behavior remains unchanged.

Estimated code review effort: 5 (Critical) | ~90 minutes

Merge Risk: 🟠 High · up to 39091

The load-test setup commits sensitive credentials and can continue after voter-import failures, while allowing threshold values the two-trustee workflow cannot satisfy; this may expose secrets and create incomplete or misleading test environments, so the PR is not ready to merge until these issues are fixed.

Replace is_local with an upload-mode enum.

false does not identify the remote upload mode at this public CLI boundary. Define an explicit UploadMode enum and map it to the legacy boolean only at the upload helper boundary.

Centralize task polling and model task states as an enum.

Remove committed Keycloak credentials.

Line 66 commits the api-key-client secret. Lines 68 and 70 commit trustee passwords. A repository reader can reuse these credentials where the development Keycloak deployment is reachable. The script also passes the client secret to step-cli as an argument.

Read these values from injected environment variables or a secrets store. Require non-empty values after argument parsing. Do not retain literal credential fallbacks.

Restrict the threshold to available trustee completions.

The script accepts any --threshold value. It completes the ceremony only as TRUSTEE1_USER and TRUSTEE2_USER. A threshold greater than two cannot be completed by this workflow.

Reject thresholds outside the supported range, or accept and process credentials for every required trustee.

Return a non-zero exit status after an import failure.

ImportVoters::run logs the error and returns normally. packages/step-cli/src/main.rs then exits with status 0. The telephone load-test setup cannot detect a failed voter import and can continue with an incomplete election event.

Return an error to main or exit with status 1 in this branch.

Proposed fix
             Err(err) => {
-                eprintln!("Error! Failed to import voters: {}", err)
+                eprintln!("Error! Failed to import voters: {}", err);
+                std::process::exit(1);

Add behavior-defining tests for the new import flow.

Add unit tests for a known SHA-256 digest and an unreadable file. Add polling tests for success, failure, timeout, and status-query errors. Extract the task-status reader or sleeper behind an injectable boundary if required.

As per coding guidelines, “Use test-driven development” and “Add unit tests for new functions, including negative and edge cases such as invalid input, None values, and parse errors.”
