The spawn's explicit embed call went with #280 step 3; the create_note result
had no other reader.

bvandeusenandClaude Fable 5 0e70a3896b feat(embeddings): per-chunk rows — schema, write path, version-aware backfill (#280 steps 2+3)
note_embeddings becomes one row per chunk: PK (note_id, chunk_index), plus
chunk_text (what this vector actually encodes) and chunker_version. Migration
0077 clears the table — embeddings are derived (0067 precedent) and the old
whole-document rows are indistinguishable from single-chunk notes, so the
startup backfill regenerates the corpus at the new shape. The backfill is now
version-aware: a future shape change is a CHUNKER_VERSION bump that re-embeds
exactly the stale notes, not another wipe.

upsert_note_embedding takes (title, body) and chunks internally — one path
for the write path, the recurrence spawn and the backfill. The recurrence
spawn's own embed call is deleted outright: create_note already embeds via
embed_note (#2056), so the spawn was a second copy of the rule. An emptied
record now CLEARS its stale vectors instead of leaving them findable.

`f"{title}\n{body}"` was written out four times. #2486 found three — the write
path, the recurring-task spawn, the startup backfill. The guard added here
found the fourth immediately, and it was the one that mattered most.

`dedup.find_duplicate_note` built the same string as a QUERY, compared against
embedded documents. Shaped differently from the corpus it searches, the gate
degrades silently: it still returns neighbours, just less apt ones, and nothing
says the query and the index stopped agreeing. The spawn path has the same
shape of risk — a recurring task embedded differently from everything else is
ranked against documents it doesn't match.

None of the four had diverged. That is what makes this worth doing now rather
than after: they are identical today, so collapsing them is a no-op, and the
whole point is that the next change to the shape can't hit three of four.

Which is imminent. #2486 measured a dev-log separating from five unrelated
dev-logs by 0.023 where a snippet separates by 0.153 — the difference being
that a snippet states its purpose twice in a short document. Whether that shape
is right is the open question; testing an alternative against four copies would
mean testing a shape that isn't the one in production. This is the precondition
the issue named.

The guard is source inspection, matching the f-string pattern rather than a
variable name, so a copy that renames its locals is still caught. A behavioural
test cannot see this: an inlined copy produces the same string today and
diverges the day the shape changes.

bvandeusenandClaude Opus 4.8 b255a0f90e refactor: rename package fabledassistant -> scribe (code-only)
CI & Build / Python lint (push) Successful in 3s
CI & Build / TypeScript typecheck (push) Successful in 35s
CI & Build / Python tests (push) Successful in 54s
CI & Build / Build & push image (push) Successful in 1m14s
Renames src/fabledassistant -> src/scribe and all imports, plus the
default DB name and DB user/password (fabled -> scribe) in config +
compose. 952 refs / 154 files. Reverses the old 'internal name stays
fabledassistant' convention.

Code-only: live databases are still physically named 'fabledassistant'.
Deployed environments must set POSTGRES_DB / POSTGRES_USER (or rename the
DB) since the defaults now resolve to 'scribe'. Repo (FabledScribe), git
host (fabledsword), MCP (fabled-git) and the image name (fabledscribe)
are intentionally unchanged.

ruff check src/ clean locally; CI (typecheck + pytest) is the gate.
