Inline comments:
In `@crates/analyzer/src/fsm/runtime.rs`:
- Around line 74-76: Update RtFsmTransition and its is_final method to store and
return an explicit final-state boolean instead of comparing name with "exit".
Modify every RtFsmTransition construction, including simulator setup and tests
in this file, to initialize the new field according to whether the transition is
terminal.
- Line 111: Update RtFsmBuilder::push to retain the duplicate-key result from
OrderedCollector::push, then make try_build reject any duplicate
RtFsmTransition::order_key() with AnalyzerError::Validation, matching the native
builder’s behavior.
In `@crates/analyzer/src/lib.rs`:
- Line 9: Curate the analyzer crate’s public API in lib.rs: make context and
ref_tree private, expose only supported items through explicit pub use
declarations such as RefTreeEntity, and keep internal items pub(crate). Update
cross-crate imports to reference the analyzer package root rather than its
internal modules.
In `@crates/analyzer/src/ref_tree/mod.rs`:
- Line 120: Replace recursive traversal with explicit stack-based iteration
across all affected sites: update validate_acyclic in
crates/analyzer/src/ref_tree/mod.rs at lines 120-120 to validate parent chains
iteratively, construct child nodes iteratively at lines 133-133, and convert the
reference tree iteratively in crates/analyzer/src/resource/tree.rs at lines
75-75. Preserve cycle detection and tree structure while preventing stack
overflow for arbitrarily deep valid trees.
In `@crates/open/src/revision.rs`:
- Line 42: Update the Git command construction in validate_remote to terminate
option parsing before passing the remote argument, ensuring leading-dash
scp-style values are treated only as remotes and not fetch options.
In `@domains/query_engine/analyzer/src/lib.rs`:
- Around line 57-58: Update PlanTree::try_new or the parent-link validation
before PlanTree::build to reject any plan where both parent_query_id() and
parent_plan_id() return Some, returning AnalyzerError instead of treating the
plan as both root and child. Preserve valid plans with either one parent link or
neither.
In `@experimental/vibe/simulator/analyzer/src/boilerplate/plan.rs`:
- Line 75: Update the reference-tree parent lookup to use the plan’s direct
parent when parent_plan_id is present, matching the topology preserved by to_ui,
instead of always using self.0.accumulator().parent_query_id. Keep query
parenting only for plans without a parent plan.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Do not derive is_final from the state name "exit".
RtFsmTransition.name is an application-supplied string. Two failures follow from the name comparison:
- An application whose final state is not named
"exit"reportsis_final() == falsefor every transition, so consumers treat a complete FSM as unterminated. This contradicts the multiple-final-state support added in this PR. - A non-terminal state named
"exit"reportsis_final() == true.
Carry the flag as data instead of inferring it from the name.
As per path instructions: "Avoid magic sentinel strings that can collide with real identifiers; use typed variants, opaque IDs, or prove collision freedom."
🐛 Proposed fix
pub struct RtFsmTransition {
pub name: String,
pub sequence: u16,
+ /// Whether this transition ends the FSM's dynamic lifetime.
+ pub is_final: bool,
pub usages: Vec<RtFsmStateUsage>,
pub timestamp: TimeUnixNanoSec,
pub attributes: Vec<DynamicAttribute>,
} fn is_final(&self) -> bool {
- self.name == "exit"
+ self.is_final
}Callers that construct RtFsmTransition, including the simulator boilerplate and the tests in this file, must set the new field.

Reject duplicate transition keys in RtFsmBuilder.
RtFsmTransition::order_key() uses (timestamp, sequence), but RtFsmBuilder::push discards the duplicate flag returned by OrderedCollector::push. try_build therefore accepts transitions with the same key. Equal-key transitions are kept in arrival order, but they do not define a valid unique state order and create zero-width state spans. The native builder rejects the same input with AnalyzerError::Validation.
Store the duplicate key in RtFsmBuilder and reject it in try_build, as the native builder does.

Terminate Git option parsing before remote.
validate_remote accepts scp-style SSH URLs but does not reject leading-dash values. Git can therefore parse a crafted remote as a fetch option before the trust check's approval matters.

Reject plans with two parent links.
parent_query_id() and parent_plan_id() can both return Some. If a plan has parent_query_id() == Some(query_id) and parent_plan_id() == Some(its_own_id), PlanTree::try_new selects it as a root and PlanTree::build selects it as its own child. The recursion does not terminate and can overflow the stack instead of returning AnalyzerError.
Encode the parent relationship as one exclusive variant, or reject plans that have both parent IDs before tree construction.

Use the direct plan parent in the reference tree.
When parent_plan_id is present, this code still places the plan directly under its query. This flattens nested plans and gives reference-tree consumers incorrect topology. to_ui already preserves the direct parent.

Do not classify every Queueing event as initial.
The schema permits sending -> queueing, and FsmHandle::queueing emits the transition through the existing handle, preserving the same FSM UUID. AnalyzedFsmBuilder only detects missing events when the first transition is non-initial, the topology is invalid, or the final transition is absent. A stream that starts at this later Queueing event can therefore pass validation after Exit and produce inaccurate state spans.
Use a distinct non-initial requeue transition, or create a new Task entity when a new queueing lifetime starts.
