Type Alias DeadCodeOutput 

pub type DeadCodeOutput = CheckOutput;

Concrete dead-code output contract returned by typed programmatic runs.

Fields

schema_version: SchemaVersion

Dead-code output schema version; currently [CHECK_SCHEMA_VERSION].

version: ToolVersion

Fallow CLI version that produced this output.

elapsed_ms: ElapsedMs

Wall-clock analysis duration in milliseconds.

total_issues: usize

Total findings across all issue arrays; excludes next_steps.

entry_points: Option<EntryPoints>

Entry-point totals per source, when the analysis recorded them.

summary: CheckSummary

Per-category finding counts.

results: AnalysisResults

Full analysis results, flattened so each issue array sits at the envelope root.

baseline_deltas: Option<BaselineDeltas>

Count deltas against the matched baseline, in baseline runs.

baseline: Option<BaselineMatch>

Which baseline snapshot was matched, in baseline runs.

regression: Option<RegressionResult>

Regression verdict against the baseline, in --fail-on-regression runs.

meta: Option<Meta>

_meta block with docs and rule definitions, when --explain was passed.

workspace_diagnostics: Vec<WorkspaceDiagnostic>

Non-fatal diagnostics about the project itself, from all three stages that record them (issue #473):

• workspace discovery, at config load: undeclared-workspace, malformed-package-json, glob-matched-no-package-json, malformed-tsconfig, tsconfig-reference-dir-missing;
• source discovery, during the file walk: skipped-large-file, skipped-minified-file, source-read-failure;
• dead-code analysis, from the dependency-catalog and override detectors: malformed-pnpm-workspace-yaml, bun-lockb-override-resolution-skipped.

Analysis-stage kinds therefore reach only the envelopes whose run includes a dead-code analyze pass, never a standalone fallow dupes --format json. path is project-root-relative with forward slashes; the array is omitted when empty. The same list is repeated on each top-level command’s envelope so single-command consumers see it without having to look at a separate top-level field.

next_steps: Vec<NextStep>

Read-only follow-up commands computed from this run’s findings, emitted at the JSON root so an agent acting on the output is pointed at fallow’s adjacent verification capabilities (trace, complexity breakdown, audit, workspace scoping). Each command is runnable as-is and never mutating; see [NextStep] for both contracts. Omitted when empty or when FALLOW_SUGGESTIONS=off; does NOT contribute to total_issues.
