+# Plugin manifests declare Plugin SDK compatibility
+
+The historical `block_core` compatibility field predates the standalone
+Plugin SDK and is ambiguous: CMS core and the plugin-facing SDK have separate
+release cycles. Interpreting the same constraint against both versions can
+select an artifact that the host cannot load or reject one that is compatible.
+
+Decision: `[compatibility]` gains an optional `plugin_sdk` string containing a
+semantic-version constraint for the plugin-facing SDK/ABI, for example
+`plugin_sdk = ">=0.3.7"`. Manifest parsing preserves the value verbatim;
+registry and host resolvers own constraint validation and matching.
+
+An omitted or empty value is undeclared compatibility, not a wildcard.
+Automated resolution against a host SDK version must fail closed, except for
+an explicitly bounded migration policy for releases published before this
+field existed. `block_core` remains a separate historical constraint and is
+not reinterpreted as the CMS application's own version.
+
+Consequences:
+
+- Plugins can state the actual SDK/ABI range they require.
+- CMS core can evolve independently of the public Plugin SDK.
+- New releases must declare `plugin_sdk` to participate in automatic
+  SDK-compatible selection.

+# Bridge providers receive authenticated caller identity
+
+Bridge payloads are guest-controlled. A provider that uses a payload field as
+an ownership namespace lets one plugin impersonate another plugin and mutate
+or claim its managed records. The consumer-to-host `BridgeInvokeRequest`
+cannot safely carry identity because the consumer constructs that message.
+
+Decision: the host derives the caller plugin from the loaded module or native
+plugin registration. It passes that identity to the provider in
+`BridgeCallRequest.caller_plugin` and, for Go providers, through
+`plugin.WithBridgeCallerPlugin`. Providers read it with
+`plugin.BridgeCallerPlugin` and fail closed when an ownership-sensitive call
+has no authenticated caller.
+
+The new host-to-provider protobuf field is additive. Older providers ignore
+it. New ownership-sensitive providers intentionally reject calls from older
+hosts that cannot authenticate a caller. Hosts must never copy a caller name
+from opaque bridge payloads or a consumer-authored capability field.
+
+Consequences:
+
+- Providers can derive durable ownership from an authenticated principal.
+- Bridge payload schemas do not need security-sensitive source fields.
+- Native and Wasm providers observe the same caller context contract.
+
+Keywords: plugin bridge, caller identity, authentication, ownership,
+BridgeCallRequest, WithBridgeCallerPlugin, Wasm, confused deputy

+# Register sees the current guest host services
+
+Go guest plugins can declare capability-backed runtime surfaces from their
+`Register` callback. Bridge providers are the first such surface: the provider
+stores its invokable value in the guest-local bridge stub while the stub tells
+the CMS host that the named service exists.
+
+`Serve` previously assigned the package-level guest runtime only after
+`newGuest` returned. Because `newGuest` runs `Register` synchronously,
+`HostServices()` returned an empty `CoreServices` value during registration.
+Plugins that correctly nil-checked the bridge silently skipped registration.
+The CMS could therefore mark a Wasm plugin loaded while consumers failed with
+`bridge: no service registered` during a later load hook.
+
+`newGuest` now makes the guest under construction current for the synchronous
+registration pass and restores the previous runtime before returning. `Serve`
+then installs the completed guest as before. This keeps construction isolated
+for native tests while making the documented `HostServices()` escape hatch
+truthful during `Register` on every pooled Wasm instance.
+
+Alternatives rejected were moving bridge registration into `Load`, which runs
+on only one pooled instance, and adding bridge names only to the manifest,
+which would advertise host availability without installing the guest-local
+`BridgeInvokable` value needed by `HOOK_BRIDGE_CALL`.
+
+Consequences:
+
+- Bridge services registered from `Register` exist on every pooled guest
+  instance and remain callable after CMS startup and hot swap.
+- A regression test exercises the observable `Serve` plus
+  `HOOK_BRIDGE_CALL` contract instead of relying on initialization internals.
+- No ABI or protobuf change is required; consumers need a plugin SDK release
+  containing the corrected Go guest runtime.
