Correct the strict-comparison explanation.
upstream.value != null is an inequality check. A strict comparison would not make this check “always false”; defined values still compare as present. State only that this expression language normalizes absent values to null and gives == and === identical semantics.

This test may pass for the wrong reason.
.replace('enabled: true\n', '') deletes the key and its newline, but not the leading indentation of that line. The remaining spaces merge into the next line, so variable_name: regions becomes over-indented. The YAML parser is likely to reject the document before the schema sees it. The test then proves nothing about the required enabled flag.
Assert the error text, or mutate the parsed object instead of the YAML string.
💚 Proposed fix
- const yaml = serializeDeepnoteFile(file).replace('enabled: true\n', '')
+ const yaml = serializeDeepnoteFile(file).replace(/^(\s*)enabled: true\n/m, '')
expect(yaml).not.toBe(serializeDeepnoteFile(file))
- expect(() => deserializeDeepnoteFile(yaml)).toThrow()
+ expect(() => deserializeDeepnoteFile(yaml)).toThrow(/enabled/)📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Use a key-safe producer map.
IDENTIFIER accepts toString, constructor, and __proto__. A normal object inherits these keys. A step that exports toString therefore fails the duplicate-export check even though no step produced it.
Use Map<string, string> internally, then serialize it with Object.fromEntries() for PipelinePlan.producedBy. Add coverage for inherited-key variable names.

Reject duplicate step ids during planning.
Two notebook-function blocks can produce two planned steps with the same id. pipelineForPlan() stores pending steps in a Map keyed by this id but waits for plan.steps.length settlements. One step overwrites the other, then execution fails with The pipeline stalled.
Validate unique block ids before building drafts. Add a plan-time error test.

A second concurrent step failure becomes an unhandled rejection.
Line 338 awaits Promise.race(running.values()) only. Each promise stored at line 305 has no other consumer. If two steps run at the same time and both reject, the race propagates the first rejection out of pipelineForPlan. The second promise stays rejected and unobserved. Node then emits unhandledRejection, which terminates the process by default and hides the original error.
Two executor throws in one wave are enough to trigger this. allowFailure does not help, because a throw is not a failed result.
Attach a handler when the promise is stored, and re-raise the recorded error after the race.
🐛 Sketch of a fix
+ const errors: unknown[] = []
...
- running.set(
- step.id,
- Promise.all(
+ const work = Promise.all(
...
- })
- )
+ })
+ work.catch(error => {
+ errors.push(error)
+ })
+ running.set(step.id, work)
}
if (running.size > 0) {
- await Promise.race(running.values())
+ await Promise.race([...running.values()].map(p => p.catch(() => undefined)))
+ if (errors.length > 0) {
+ throw errors[0]
+ }
}Note that swallowing the race rejection requires the loop to also stop draining running, otherwise a failed step never leaves the map. Track settlement explicitly instead of relying on rejection to exit.

A pipeline can live in a file instead of in code: a notebook marked
isPipeline: truewhosenotebook-functionblocks each name a module notebook, its inputs, and the values it publishes. The encoding is the one deepnote.com already stores for module imports, extended with four typed keys, so the same file can later be executed natively by the product against the same planner.Dependencies come from variable flow
An input with
variable_namereferences a value another step exports throughfunction_notebook_export_mappings. That is the dependency edge; nothing is declared twice, and independent steps are independent by construction. Identifiers inrun_if, thefor_eachsource, and everyfallbackalternative are edges too.The primitives

for_eachwhose source was skipped. A failed step withoutallow_failurefails the pipeline; unrelated steps in flight finish. The rejection carries the engine'spartialrun plus the runner'svariables,skippedandfailedso far, so a caller can render what finished.Interpreted, not executed
The parent is read as a manifest. Deepnote's block engine runs blocks strictly in order, so executing the parent would serialize the fan-out into one run with one status.
planPipeline(file)returns the graph without running anything. Plan-time errors cover everything checkable without running: missing or duplicateisPipeline, unknown references, duplicate exports, a step naming no notebook,for_each_aswithoutfor_eachor shadowing an export, malformed conditions, cycles.Deliberately not JavaScript
A pipeline definition is data. The condition language has no
eval, no calls, no assignment, own-property lookups only.europe.__proto__evaluates to false andfetch("x")fails at plan time. One rule for every comparison operator: numeric when both operands are numbers or numeric strings, strict otherwise, because the runs API delivers inputs as strings.Conformance fixtures
