A note or task created through MCP was not semantically searchable until the next restart's backfill ran. Embedding fired at the five REST route handlers and nowhere else; the MCP tools call the service directly, so they skipped it. The shape of this bug is the reason to care: it is invisible on an instance that redeploys constantly (this one does, per rule 46) and permanent on one that doesn't. Rule 115 — the product has to stand up for the install that restarts twice a year, not just for the one that restarts hourly. Moved to services/notes.embed_note(), called from create_note and update_note, and deleted from all five routes. Every caller — REST, MCP, recurrence, snippets — now gets it by construction rather than by remembering. Two things fall out of having one implementation instead of six: - It uses note.user_id, the OWNER. The routes were inconsistent: some passed the caller's uid, some the owner's. On a shared record the caller's id mints a second embedding row that nothing reads. - services/snippets.py's _embed_snippet existed only because snippets are created via MCP and the routes couldn't cover them. Every one of its four call sites goes through notes_svc, so the helper and its four calls are gone, along with the eight test patches that existed to neutralise it. RuntimeError (no running loop — unit tests, scripts) and any indexing failure are both swallowed: a write that succeeded must not be failed by its index.

"""Merge records what it absorbed (#2087).

|
|
|
Merging keeps the target's scalar fields, unions locations + tags, and trashes
|
|
the sources. Without provenance the fact that a variant ever existed survives
|
|
only in the trash — and only for someone who already knew to go looking. So the
|
|
survivor carries `merged_from`, written to the body and the indexed mirror from
|
|
one value, and ordinary edits must carry it forward rather than erase it.
