Update a stale-key row through its requested document id - #146
Conversation
`memory_docs` upserts on `(namespace, key)` but its primary key is
`document_id`, so a write whose key was new while a row of the same
namespace already held its requested id failed with `UNIQUE constraint
failed: memory_docs.document_id`. Sync providers keyed documents by title
before openhuman#4953 while already passing their stable `{toolkit}:{id}`;
re-syncing such an item under the id key hit its own old row, and the
GitHub pipeline, which does not tolerate scope errors, aborted every run
that reached it (openhuman#6147).
Resolve the row before writing, in both the full and the metadata-only
path: a row found by key keeps its id whatever was requested (the DO UPDATE
never rewrote the id, so chunks and the graph job went under an id no row
had); a requested id that names a same-namespace row under another key
re-keys that row inside the write transaction and updates it; an id owned
by another namespace falls back to the derived id instead of failing the
write; a blank id is no request.

- Around line 280-282: Within the transaction in the document write flow,
re-resolve the current key for the document identity after acquiring the
transaction and before inserting or rekeying, rather than relying on the
initially resolved key. Apply the same identity re-resolution to the
metadata-only write path, using the existing document lookup/rekey helpers and
preserving conflict handling.

Included review availability: Your plan provides up to 1 included review per hour; 0 remain after this review.
The identity resolution runs before the markdown sidecar is written and outside the connection lock, and the per-key write lock only serialises writers of one key. A writer reaching the same document through another key could re-key the row in between, and the upsert's ON CONFLICT(namespace, key) would then miss the row and trip the primary key. Look the row up by id inside the transaction and move it under the key being written there, on both write paths; the early resolution now only settles the id and created_at.

Assert that the legacy row is updated in place
The test asserts that arr.len() == 1 and that the returned document's key is the stable ID, but does not check that the content (body) of the row is the new value ("issue body v2"). Without checking the content, the test could pass even if the re-sync inserted a second row with the stable key and left the legacy row untouched — the count would be 2 only if both rows share the same (namespace, key) pair (which they do not: old key is title, new key is stable_id). Actually, because the old row has key=title and the new storage uses key=stable_id, a naive implementation could create a second row, making arr.len() == 2. The count-1 assertion is insufficient; add an assertion that the content is "issue body v2" to prove the update happened in place.

Summary
memory_docsupserts on(namespace, key), but its primary key isdocument_id. A write whose key was new while a row of the same namespace already held its requested id failed withupsert memory_docs: UNIQUE constraint failed: memory_docs.document_id. That is exactly a Composio GitHub document a provider stored under its title before openhuman#4953 and re-syncs under the stablegithub:{id}key since — the GitHub pipeline does not tolerate scope errors, so one such item aborted the whole run, left the cursor where it was, and aborted again every tick (openhuman#6147).Both write paths now resolve the row before writing (
resolve_document_identity):(namespace, key)keeps its id whatever was requested — the upsert'sDO UPDATEnever rewrotedocument_id, so the chunks and the graph job used to go under an id no row had;created_at, chunks, sidecar and graph relations are keyed by the id and stay put). Which key the row carries is re-checked inside the write transaction (rekey_document_in_namespace, one primary-key lookup per write), because the resolution runs before the sidecar write and the per-key lock only serialises writers of one key — a writer reaching the same document through another key can move it in between;Related issue

The loser's insert still trips the primary key once, and its next write resolves the owner and takes the derived id; the interleaving cannot be forced deterministically from the public surface.
