Bug: bare model names in init defaults cause silent fallback to mock embeddings

[sparkling]

Embedding model defaults across the CLI use bare names (e.g. all-mpnet-base-v2) instead of prefixed names (Xenova/all-mpnet-base-v2). Additionally, ControllerRegistry does not pass embedding config to AgentDB, causing it to fall back to a different default model. Both issues cause @xenova/transformers to silently fail, and all semantic search degrades to hash pseudo-embeddings.

Bug 1: Bare model names in defaults

File	Value	Should be
init/types.ts FULL_INIT_OPTIONS	all-mpnet-base-v2	Xenova/all-mpnet-base-v2
init/types.ts DEFAULT/CODEX_INIT_OPTIONS	all-MiniLM-L6-v2	Xenova/all-MiniLM-L6-v2
commands/init.ts wizard choices + CLI flags	bare names	prefixed names
mcp-tools/embeddings-tools.ts enum + default	bare names	prefixed names
mcp-tools/hooks-tools.ts status model	bare name	prefixed name

Bug 2: ControllerRegistry does not pass embedding config to AgentDB

@claude-flow/memory/src/controller-registry.ts line 723:

this.agentdb = new AgentDBClass({ dbPath });  // missing embeddingModel + dimension

The registry reads getEmbeddingConfig() at line 713-715 and caches the dimension, but never passes the model to AgentDB. AgentDB falls back to its own default (MiniLM 384-dim) instead of the configured model (mpnet 768-dim). The bridge then rejects the 384-dim result because config expects 768.

Fix

1. Prefix all bare model defaults with Xenova/
2. Pass embeddingModel and dimension from registry to new AgentDBClass()

Verification

After fix: memory store writes 768-dim Xenova/all-mpnet-base-v2 embeddings, memory search returns semantically relevant results.

Fix: #1517

[ruvnet]

Fixed in v3.5.53 (PR #1535). All bare model names prefixed with Xenova/ across 8 files. ControllerRegistry now passes embeddingModel to AgentDB constructor.

Closed via v3.5.53
