fallow: codebase intelligence for TypeScript and JavaScript

Render a saved --format json results file in another format without re-running analysis. Analyze once, retain JSON as the provenance-bearing artifact, then derive every CI presentation from that same result.

fallow check --type-aware --format json -o results.json
fallow report --from results.json --format github-annotations
fallow report --from results.json --format pr-comment-github > comment.md
fallow report --from results.json --format review-github > review.json

The command dispatches on the envelope’s kind, so any saved fallow result renders: dead-code, dupes, health, audit, security, or the bare combined run. Supported targets are:

github-annotations and github-summary
codeclimate and sarif
pr-comment-github and pr-comment-gitlab
review-github and review-gitlab

The PR-comment and review targets preserve the saved audit conclusion, diff positions, ownership grouping, and repository path prefix. Type-aware check and audit results render their final semantically refined findings rather than the earlier syntactic candidates. When semantic evidence is required but incomplete, the analysis run fails closed instead of saving an apparently clean presentation. GitHub annotations and summaries are log-based, so they work on fork PRs without a write token. PR-comment and review envelopes still need the provider posting step described in CI integration.

Options

Flag	Description
`--from <PATH>`	Path to a fallow JSON results file produced by `--format json` (required)
`-f, --format <FORMAT>`	Target format: `github-annotations`, `github-summary`, `codeclimate`, `sarif`, `pr-comment-github`, `pr-comment-gitlab`, `review-github`, or `review-gitlab`
`-r, --root <ROOT>`	Project root directory (used for repository-root path rebasing)
`-q, --quiet`	Suppress progress output on stderr

Exit code

Rendering is exit-neutral: fallow report exits 0 even when the saved file contains findings. Gating belongs to the analysis run that produced the file (--fail-on-issues, the audit verdict); use that run’s exit code in CI and keep report as a pure rendering step.
