src/openhuman/memory_sources/status.rs
`source_status` derived `chunks_pending` from `mem_tree_chunks.embedding`, a vestigial column that is not in the canonical tinycortex schema and is only added at runtime by `add_column_if_missing`. No production writer ever populates it — embeddings live in the `mem_tree_chunk_embeddings` sidecar keyed by `(chunk_id, model_signature)` — so the column is NULL for every row and `chunks_pending` always equalled `chunks_synced`. Resolve a chunk when it has a vector under the active signature, has a re-embed tombstone for that signature, or was dropped by the admission gate, mirroring `list_sync_statuses` and `has_uncovered_reembed_work`. Refs tinyhumansai#5329
`migrate_legacy_embeddings_to_sidecar` preserves `mem_tree_chunks.embedding` after copying it into the sidecar, so a pre-sidecar vault still carries a usable signal there. Treat a non-NULL legacy blob as resolved alongside the sidecar/tombstone/dropped terms so vaults that predate the sidecar do not regress to "everything pending", and cover it with a dedicated test. Refs tinyhumansai#5329
The doc comments described `chunks_pending` as counting chunks whose `embedding IS NULL` and pointed at the pre-refactor `memory_sources/` path. Both are stale: the counter now resolves chunks against the `mem_tree_chunk_embeddings` sidecar under the active model signature. Comment-only; no behaviour change. Refs tinyhumansai#5329
… scan Re-authored onto the post-tinyhumansai#5328 tree (memory_sources → memory/sources) and rebased on the sidecar-based `chunks_pending` fix (tinyhumansai#5344, cherry-picked as the three preceding commits by @Mustaqeem66) so the batch and the per-source path share one pending definition. `status_list` (polled every 5s by the Memory Sources panel) previously ran one full `mem_tree_chunks` scan per source. It now folds every source's counts into `ceil(N / 128)` scans: one SELECT whose per-source columns are gated by `source_id LIKE ?n`, with the pending column embedding tinyhumansai#5344's exact resolved-predicate (active-signature sidecar vector / re-embed tombstone / dropped lifecycle / legacy blob) inside the gate's `THEN` branch. All reads share the one process-wide chunk-DB connection mutex, so fewer scans — not concurrency — is the only available lever. The nested `CASE` (rather than `LIKE ?n AND NOT(<pred>)`) is deliberate: it reproduces `source_status`'s NULL-predicate → pending behaviour exactly, and because SQL evaluates only the taken branch the `EXISTS` sub-selects run only for a row's own source. If the batched query ever fails, `status_list` falls back to the per-source path, so a query regression degrades latency, never correctness. Equivalence is pinned by a test asserting the batched result matches per-source `source_status` across all five resolution states.

Pull request overview
This PR reduces the cost of openhuman.memory_sources_status_list (polled every 5s by the Memory Sources panel) by batching per-source status computation so that multiple sources are aggregated in a single mem_tree_chunks scan, while preserving the existing per-source semantics (including the updated “pending” predicate from #5344) and falling back to the original per-source path on query failure.
Changes:
- Add a batched fast path that aggregates
(chunks_synced, chunks_pending, last_chunk_at_ms)for up to 128 sources per query, reducing scans from N per poll to ceil(N/128). - Preserve correctness by embedding the “resolved vs pending” predicate inside a nested
CASEsoNULLpredicate results still count as pending (matching the per-source logic). - Update frontend documentation/comments describing what
chunks_pendingrepresents.

- This inline comment says pending means “chunks with no vector for the active embedding signature”, but the core also treats tombstones/dropped chunks and legacy
embeddingblobs as resolved. Updating the wording will keep frontend docs aligned with the core semantics.
// Layer 1 — embeddings. Precise per-source signal (chunks with no vector for

What
memory_sources::status::status_listpowers the Memory Sources panel, whichpolls
openhuman.memory_sources_status_listevery 5s (MemorySourcesRegistry.tsx).It ran one full
mem_tree_chunksscan per source — N sources ⇒ N scans perpoll — and
mem_tree_chunksis indexed on(source_kind, source_id), which asource_id LIKE 'prefix%'predicate can't use, so each is a full table scan.Change
Fold every source's counts into
ceil(N / 128)scans. One SELECT emits threeaggregate columns per source, each gated by
source_id LIKE ?n:chunks_synced—COUNTof the source's chunkschunks_pending— the source's chunks not resolved for the activeembedding signature, using fix(memory-sources): count chunks_pending from the embedding sidecar, not a dead column #5344's exact predicate (sidecar vector under the
active signature / re-embed tombstone / dropped lifecycle / legacy blob)
last_chunk_at_ms—MAX(timestamp_ms)128 sources/batch keeps the statement under SQLite's 2000-column / 999-param caps
(128×3 = 384 cols, 130 binds). All reads share the one process-wide chunk-DB
connection mutex, so fewer scans, not concurrency, is the only lever (batching
also shortens how long the lock is held).
Why the nested
CASEThe pending column is
CASE WHEN source_id LIKE ?n THEN (CASE WHEN <resolved> THEN 0 ELSE 1 END) ELSE 0 END,not a flat
LIKE ?n AND NOT(<resolved>), for two reasons:source_statuscounts a row pending whenever the predicateis false or NULL (
CASE WHEN <pred> THEN 0 ELSE 1). A bareNOT(<pred>)maps NULL → NULL → not-counted, silently under-counting NULL-
lifecycle_statusrows. Nesting the identical inner
CASEreproduces the NULL-→-pendingbehaviour exactly.
CASEbranch, so theEXISTSsub-selects run only for a row's own source — never once per source per row —
without relying on
ANDshort-circuiting.Correctness / fallback
If the batched query fails for any reason,
status_listfalls back to theoriginal per-source path (
status_list_per_source), so a query regressiondegrades latency, never correctness.
Tests
batch_status_matches_per_source_counts— asserts the batched result equalsper-source
source_statusfield-for-field across all five resolution states(active-signature embed, superseded-signature embed, re-embed tombstone,
dropped lifecycle, legacy blob) plus genuinely-pending and empty, and pins the
absolute counts so a bug corrupting both paths identically still fails.
batch_status_spans_multiple_query_batches— 133 sources, verifies theindex→source mapping across a batch boundary.
batch_status_empty_db_is_zeroed_not_errored— theSUM/MAXNULLs of azero-row scan decode to 0 / None.
