Walks every language directory and emits a root-level manifest matching
Kotoshu::Integrity::Manifest's schema:
{ version, generated_at, repo_version, resource_count,
language_count, resources: { "<rel/path>": { size, sha256,
language, type, license?, source? } } }
279 resources across 93 languages. License/source pulled from each
language's package.json (SPDX identifier + repo URL) so the gem has
machine-readable attribution to surface in audit logs.
Re-runnable: scripts/generate_manifest.rb is idempotent modulo the
generated_at timestamp. CI should diff the committed manifest against a
fresh run on every PR.

Summary
Adds
manifest.jsonat the repo root — the source of truth that the kotoshu gem'sKotoshu::Integrity::Manifestverifies downloads against.Generated by
scripts/generate_manifest.rb, which walks each language directory, hashesindex.dic/index.aff/index.js/rules.yaml, extracts license and source frompackage.json, and emits:{ "version": 1, "generated_at": "2026-06-26T...", "resources": { "en/index.dic": {"size": 12345, "sha256": "...", "language": "en", "type": "spelling", "license": "MIT", "source": "..."} } }Result
279 resources across 93 languages.
Why
The gem's ResourceManager rejects any download whose SHA-256 doesn't match the manifest. Without this file, downloads are unsigned.
