Glossary

APK: the Android app archive the CLI reads and writes. Can be a single file or a split set (base plus config splits).

Bundle: a signed .reseam archive holding one or more patches plus the metadata needed to apply them. The unit of distribution. The CLI refuses to load a bundle whose signature doesn't verify against a trusted key.

Patch: a single named change applied to an app: "block ads", "force AMOLED dark". Patches live inside bundles and declare their compatibility, dependencies, and options.

Bundle manifest: manifest.toml inside the bundle. Holds the bundle name, author, description, format version, the engine version that packed it, and the hash of every payload file. Signed by the bundle author's Ed25519 key.

Trusted key: an Ed25519 public key a client accepts as a valid bundle signer. Bundles carry their signer key inside the archive; the client verifies the signature, then applies its own trust policy for that key.

Signing key (APK): the PKCS#8 keypair used to sign the patched APK with Signature Scheme v2. Separate from the bundle signing key. Supplied via --key and --cert, or generated automatically next to the output.

Patch selection: the set of enabled patches and their option values for one patch run. Built from the bundle's defaults and the --enable, --disable, and --option flags.

Split APK: Android's way of distributing a single app as several APKs (base plus config splits for architecture, density, or language). The CLI treats the set as one unit: patches apply across DEX files from every split.

patches.json: the release index for a bundle. Lists the bundle's identity, public key, and every release. Read by the Reseam API and Reseam Manager. Written or updated by reseam publish patches. manager.json is the same shape for Reseam Manager releases, written by reseam publish manager.

DEX: Dalvik executable. The bytecode format inside an APK. Patches operate on DEX methods, classes, and strings.
