Mechanical rename produced by scripts/msd-rename.cjs: gsd/Gsd/GSD -> msd/Msd/MSD across contents and paths, upstream package/repo coordinates -> @golem15/msd-core and golem15com/msd-core. Deep links into upstream history, sibling upstream packages, the GSD-2 import feature, CHANGELOG.md and .changeset/ are kept as-is. Hand edits on top: MSD block-letter banner and logos, LICENSE copyright line, package/plugin identity, regenerated lockfile, install-tree fixtures, derived registries and benchmark baseline; migration checksum baseline re-locked (MSD keeps its own install state, so no install had applied the old sums); sort-order and regex-escaped expectations in tests adjusted.

/**
|
|
* Embedding adapter contract — the common `HostIntegrationInterface` both
|
|
* embedding adapters satisfy (ADR-1239 Phase C-1, #1680).
|
|
*
|
|
* INTENTIONALLY MINIMAL (Phase 3 slice 1). The full six-interface-point binding
|
|
* surface (command / dispatch / model / hooks / state / artifact) is DEFERRED
|
|
* until the imperative adapter (AC2) provides a real consumer that fixes the
|
|
* shape — ADR-1239 lists the wire-shape as an open question:
|
|
* "Exact wire-shape of the initialize handshake … Where precisely to cut the
|
|
* engine↔host boundary"
|
|
* (docs/adr/1239-msd-embeddable-orchestration-engine.md#open-questions-narrowed-by-the-research).
|
|
* Freezing a 6-point contract before the imperative adapter exists would risk
|
|
* rework across Phases 3-6. This slice ships only what the declarative adapter
|
|
* (AC1) needs: the kind discriminator + runtime + install/uninstall entry.
|
|
*
|
|
* Both adapters bind the SAME engine (install-engine.cjs / the loop resolver);
|
|
* they differ in HOW — declarative projects files (lossy: drops loop
|
|
* orchestration), imperative drives host primitives in-process. See ADR-1239
|
|
* "How a capability reaches a host (two adapters, one engine)".
