GRIP - Core is the foundation library suite for the GRIP addon family. It ships seven LibStub-registered libraries that consumer addons embed via .pkgmeta externals, plus a small standalone hub UI bound to /gripcore.

What it provides

LibGRIPSchema-1.0 -- canonical schema-type registry (FourCC + version + owner).
LibGRIPEncode-1.0 -- wire-format encoder/decoder (!GRIP: envelope, deflate, base91).
LibGRIPVersion-1.0 -- schema migration helpers.
LibGRIPSnapshot-1.0 -- provider registry for unified snapshot collection.
LibGRIPDiff-1.0 -- snapshot diff producing structured change-set tables.
LibGRIPComm-1.0 -- snapshot exchange over addon messages, chunked + deflated + schema-tagged.
LibGRIPBridge-1.0 -- in-game to external bridge (clipboard frame + BattleNet community paste helper).

The lib suite handles serialization, transmission, snapshot collection, and diff comparison so consumer addons (GRIP - Enhanced Macro Sequencer, GRIP - Guild Recruitment, GRIP - Forge, GRIP - Export, plus any third-party consumer) don't have to roll their own.

Status

GRIP - Core is alpha (v0.1.x). The seven lib bodies are implemented and the in-game smoketest passes 56/56 across all groups, but the API is not yet frozen. Public-method signatures and err_table codes may change before v1.0. Pin to a specific git tag in your .pkgmeta externals if you need a stable embed during alpha.

For end users

Most players never see GRIP - Core directly -- managed clients install it as a Required Dependency for the consumer addons. If you do install it standalone, type /gripcore for the hub UI (Snapshots, Export, Diff, Version, Comm tabs), /gripcore version for the loaded-lib inventory, or /gripcore smoketest to run the 56 in-game test cases.
