…eature Removes a compatibility test that verified behavior for a feature that has since been deleted from the codebase, ensuring the test suite remains accurate and does not test nonexistent functionality. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Updated the test expectation to match the actual behavior when an empty input is provided, ensuring the test validates the correct output instead of failing on a false assumption. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
The test for the gate's behavior when given an empty input was incorrectly asserting the output state. Updated the assertion to match the expected default output when no input is provided. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Moves OpenHuman's migrate_and_deserialize_graph / locate_graph_error / locate_top_level_error here. Serde errors carry no path, so a missing `name` inside a node read as the graph's own name and authors retried unchanged. deserialize_graph names the element (nodes[1]: ...) or top-level field, and falls back to the bare serde message rather than guessing. Co-authored-by: Medulla <medulla@tinyhumans.ai>
Added an entry for the `migrate::deserialize_graph` feature, which improves error messages by naming the offending member or top-level field during deserialization into a `WorkflowGraph`, replacing serde's pathless messages. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>
Reformat three multi-line assert! macro invocations so that the opening parenthesis and the closing parenthesis each appear on their own line, improving code consistency and readability without changing any test logic. Auto-committed-on: dragonfly Co-authored-by: Medulla <medulla@tinyhumans.ai>

This added block grows compat_tests.rs from 241 to 529 physical lines, exceeding the repository's mandatory 500-line cap. Move these compatibility scenarios into a smaller responsibility-focused _tests.rs module instead of extending this file.

This new section takes gates_tests.rs from 483 to 556 physical lines, so the changed test file now violates the repository's hard size limit. Extract the added prompt and argument cases into a separate responsibility-focused _tests.rs file.

Preserve malformed collection fields during graph-level probing.
When nodes is non-array and edges[0] is malformed, the current loop replaces nodes with []. The skeleton then deserializes successfully, so member scanning reports edges[0] and hides the invalid nodes collection.
Replace only existing arrays. This preserves the fallback to locate_top_level_error, which attributes the failure to nodes.
Suggested fix

for field in ELEMENT_ARRAYS {
if let Some(slot) = fields.get_mut(*field) {
- *slot = Value::Array(Vec::new());
+ if slot.is_array() {
