🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Classify Keycloak errors from the parsed error field, not a raw substring search.
body.contains("invalid_grant") || body.contains("invalid_client") matches anywhere in the raw response text. If error_description or any other field happens to contain one of these substrings for an unrelated reason, or the body isn't the expected Keycloak JSON error shape, this misclassifies the failure as InvalidCredentials versus a generic Rejected. Deserialize the body into a small struct with an error: String field and match on that value instead.

Parse task statuses with the existing enum.
Reuse sequent_core::types::hasura::extra::TasksExecutionStatus, which defines IN_PROGRESS, SUCCESS, FAILED, and CANCELLED and provides Display and FromStr. Parse row.execution_status, match IN_PROGRESS explicitly, and return an error for unknown values. The current wildcard treats an unknown terminal state as pending, so it may wait 120 seconds and report a misleading timeout. Add tests for each status and an invalid value.

Reject max_concurrent_tenants == 0.
When at least one tenant is configured, Semaphore::new(0) gives no permits. Every tenant task then waits indefinitely on acquire_owned(), so the join_next() loop does not complete. The CLI accepts zero because the Option<usize> argument has no positive-value parser. Reject values below 1 before creating the semaphore.

In `@packages/headless-load-test/src/concurrency.rs`:
- Around line 63-82: Update run_rate_limited to return Result<Vec<T>,
JoinError>, propagating JoinSet errors with ? in both join_next draining
branches instead of discarding them. Adjust run_election_event and callers to
handle the propagated result, and add coverage for a panicking work future.
- Around line 48-49: Configure the interval created in the concurrency flow to
use Tokio’s MissedTickBehavior::Skip, preventing delayed ticker deadlines from
replaying in a burst above votes_per_second. Add a paused-time test covering
delayed executor time and verify missed starts are skipped rather than replayed.
In `@packages/headless-load-test/src/config/layers.rs`:
- Around line 68-91: Update parse_duration to use checked multiplication when
converting minute and hour amounts to seconds, returning the existing
invalid-duration error path on overflow instead of panicking or wrapping. Add
boundary tests covering overflow and maximum valid values for both m and h
units.
- Around line 58-65: Update deserialize_duration to accept both numeric YAML
values as u64 seconds and string values handled by parse_duration, preserving
the documented suffix parsing and mapping invalid inputs through serde errors.
Add a focused test covering a bare integer duration such as 30.
In `@packages/headless-load-test/src/hasura.rs`:
- Around line 72-80: Update data_or_bail to check for non-empty response.errors
before accepting response.data, and bail with format_errors whenever errors are
present. Preserve returning Ok(data) only for responses without errors, while
retaining the existing fallback for responses containing neither data nor
errors.
In `@packages/headless-load-test/src/provision/import.rs`:
- Around line 64-72: Require task execution metadata before provisioning

59-68, apply the same failure behavior to created.task_execution. Preserve

In `@packages/headless-load-test/src/provision/mod.rs`:
- Around line 96-100: Validate the result of voters::get_election_ids before

- Around line 23-60: Add behavior-defining unit tests for upload_document in

- Around line 91-112: Update prepare_ballot and the
prepare_singular_ballot/prepare_multi_ballot helpers to pass VoterSigningPolicy

production classification logic.

Tokio 1.x tokio::time::MissedTickBehavior default Burst interval documentation
💡 Result:
In Tokio 1.x, the default MissedTickBehavior for an Interval is MissedTickBehavior::Burst [1][2]. When an interval is created using tokio::time::interval or tokio::time::interval_at, it defaults to the Burst strategy to maintain backward compatibility [1][3]. Under this behavior, if the interval misses one or more ticks (for example, if the execution of the task takes longer than the interval duration), the Interval will fire ticks as rapidly as possible until it has caught up to the current time [1][4]. Unlike other behaviors such as Skip or Delay, the Burst strategy does not alter the timing of the ticks themselves compared to what they would have been had no ticks been missed; it simply causes the interval to "burst" through the missed ticks to realign with the original schedule [1][3]. You can change this behavior for an existing Interval by using the set_missed_tick_behavior method [2][5].

Configure missed ticks to skip instead of burst.
When executor delay causes multiple ticker.tick() deadlines to be missed, Tokio’s default MissedTickBehavior::Burst can replay them and start a catch-up burst above votes_per_second. Set MissedTickBehavior::Skip and add a paused-time test that confirms missed starts are not replayed.

JoinSet::join_next returns Err(JoinError) when a work task panics or is cancelled.

serde_yaml 0.9 deserialize YAML numeric scalar into String serde::Deserialize String behavior
💡 Result:
In serde_yaml 0.9, the deserialization of a YAML numeric scalar into a String is generally supported when the target type is explicitly known (e.g., a field defined as String in a struct) [1][2]. However, this behavior can be brittle and prone to failure in specific architectural contexts, primarily due to how Serde handles type information and buffering [1][2]. Key technical observations regarding this behavior include: 1. Standard Deserialization: When you deserialize a simple structure where a field is known to be a String, serde_yaml successfully converts numeric YAML scalars into their String representations [1][2]. 2. Contextual Failure (Flattening and Untagged Enums): The conversion often fails when using #[serde(flatten)] or untagged enums [1][2]. In these cases, the deserializer may attempt to determine the type before it has sufficient context that a String is required. Because the YAML scalar is identified as a number (e.g., an integer) early in the process, the deserialization logic fails when it subsequently expects a String but encounters a numeric type [1][2]. 3. Internal Buffering: Issues arise because certain Serde features, such as flattening, introduce internal buffering that can disrupt format-specific features of the deserializer, causing it to lose the flexibility to "coerce" a number into a string [2]. 4. YAML Specification Compliance: Serde_yaml adheres to the YAML specification for tag resolution [3]. If a scalar is not explicitly quoted, it is resolved based on its content (e.g., matching the regex for an integer) [3]. Relying on the library to perform implicit type coercion from a number to a string is discouraged in complex structures because it depends on the deserializer's ability to backtrack or defer type decisions, which is not always possible with the Serde data model [1][2]. For robust code, it is recommended to ensure that YAML data is quoted if it must be treated as a string (e.g., '123' instead of 123) when working with flattening or untagged enums, as this explicitly signals the type to the parser and avoids reliance on implicit coercion [4][1][2].

site:docs.rs/serde_yaml/0.9 serde_yaml String numeric scalar deserialize StringVisitor
💡 Result:
In serde_yaml 0.9.34, deserializing directly into Stringdoes not convert numeric YAML scalars to strings:
value: 123#[derive(Deserialize)]structConfig{value:String,}This fails because deserialize_string delegates to deserialize_str, which only accepts scalar text and calls visit_str; numeric scalars are rejected rather than passed through StringVisitor. (docs.rs)
However, deserialize_any recognizes numeric-looking scalars and invokes numeric visitor methods (visit_u64, visit_i64, etc.). (docs.rs)
Use quoted YAML (value: "123"), deserialize into a numeric type, or implement a custom deserializer accepting both strings and numbers.

data_or_bail discards errors when the response carries partial data.
GraphQL permits a response with both data and errors. This function returns Ok(data) first, so those error messages are dropped. Provisioning callers such as provision/import.rs then find the field None and report "returned no data", which hides the server's actual message and makes a failed run hard to diagnose. Bail when errors is non-empty, regardless of data.

reqwest 0.12.24 ClientBuilder timeout connect_timeout default documentation
💡 Result:
In reqwest version 0.12.24, the default timeout behavior for ClientBuilder depends on whether you are using the asynchronous or blocking client [1]. For the asynchronous reqwest::Client: - The default timeout is None (no timeout) [1]. - The connect_timeout default is None [2]. For the blocking reqwest::blocking::Client: - The default timeout is 30 seconds [2][3]. - The connect_timeout default is None [3]. These settings can be customized using the.timeout(duration) and.connect_timeout(duration) methods on the ClientBuilder [2][3]. The timeout method applies to the entire request (connect, read, and write operations), while connect_timeout specifically limits the time spent establishing the connection [2][3].

Keep VoterSigningPolicy as an enum.
prepare_ballot converts the policy to bool, and both preparation helpers use that value to decide whether to sign. If a new policy variant is added, it will silently follow the unsigned path. Pass VoterSigningPolicy to the helpers and match each variant explicitly.

Extract the classification into one function and test that function.
The test helper classify copies the match arms from cast_vote. The tests therefore verify the copy, not the production path. A later change to the arms in cast_vote keeps all four tests green.
Move the classification into a private function and call it from both places.

Remove the fixed voting-portal client dependency.
Accept the voter client configuration through the load-test configuration layer. Validate unsupported client and secret combinations before the run starts. If only voting-portal is supported, represent and document that restriction explicitly.
As per coding guidelines, “Design features to be client-agnostic rather than implementing client-specific behavior” and “handle incompatible combinations explicitly through validation, warnings, or documentation rather than silently breaking.”
