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, 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.

Execution plan: 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.

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