Every CoreServices interface (core/plugin/deps.go) now has a guest-side stub
that marshals to the WO-WZ-001 capability messages and dispatches through the
generic host_call transport, so plugin service code compiles and runs
unchanged against content.Content, settings.Settings, plugin.PluginBridge, etc.
- core/plugin/wasmguest/caps/: one file per family (17 families, 38 methods),
a var _ <iface> = (*stub)(nil) compile proof each, and NewCoreServices(call)
assembling them. The transport is injected (CallFunc) so marshaling is
natively testable; the wasm shim binds it to CallHost, DESCRIBE probes pass
nil (capability calls fail cleanly instead of nil-panicking).
- Error mapping wraps AbiError with <family>.<method> context and maps
DEADLINE_EXCEEDED onto context.DeadlineExceeded.
- RAGService.RegisterContentFetcher stays guest-side (RAGStub) for
HOOK_RAG_FETCH dispatch; Query/OnContentChanged marshal out. dispatch.go and
describe.go now source fetchers from the caps RAG stub.
- caps_roundtrip_test.go: fake transport + 76 deterministic golden payloads
(family_method_{req,resp}.pb) covering 100% of families, plus error-mapping,
deadline, nil-transport, and guest-side-fetcher tests. WO-WZ-006 replays the
same goldens to prevent host/guest drift.
- Acceptance: testdata/fixture Load hook calls deps.Content/Settings/Bridge
unchanged (compiles for wasip1); caps_wasmhost_test.go drives it end-to-end
through a real wazero module + fake host_call table.
- Disposition table in docs/wasm-abi.md: every member stub | host-side
(Pool, Interceptors, AppURL/MediaPath, CoreServiceBindings host-side).

// NewCoreServices assembles the guest-side CoreServices value plugins receive

|

// The transport is injected (not a package global) so the marshaling logic is

// natively testable with a fake CallFunc; the wasm shim (package wasmguest,

|
// wasip1) passes its host_call-backed CallHost. A nil call yields stubs that
|
|
// fail every capability with a clear "no host transport" error — the shape
|
|
// used by DESCRIBE probes, which never reach a live host.
|
|
//
|
|
// Members intentionally left zero because they do NOT cross as capability
|
|
// calls (all documented in core/docs/wasm-abi.md §"Capability calls"):
|
|
//
|
|
// - Pool → the db.* driver messages (db.proto)
|
|
// - Interceptors → host-side connect options; RBAC from the manifest
|
|
// - MediaPath / AppURL → delivered in LoadRequest.host_config at load
|
|
// - CoreServiceBindings → static manifest.core_service_bindings; host mounts
