fix(memory_sources): Composio dispatch in Apply-all, and seal the tree after a connector sync - #6011
Conversation
…Apply-all
The per-row Sync button special-cased Composio; the Apply-all sweep did not.
It sent every enabled row through `MemorySourceSync::run_source_sync`, which
the driver refuses for this kind ("... is synced through the connector module,
not this engine"), so "sync everything" failed for exactly the rows a user
reaches for it to fix.
Two call sites open-coding one rule is how they drifted, so the decision is now
one pure function — `sync_dispatch` over the registry entry, returning
`SyncDispatch::{Connector, Driver}` — and both sites match on it. The sweep's
trigger closure takes the whole entry rather than the id, because routing needs
the kind, the connection and the per-source cap.
The sweep also hard-errored as a whole when `as_source_sync()` answered `None`,
which for a Composio-only profile turned Apply-all into one flat refusal over a
capability none of its rows use — the same finding the row-level path already
carries (tinyhumansai#5932). The family is now resolved as an `Option` and refused per row,
which is what this sweep already aggregates (tinyhumansai#5820).
The reason stays `manual`: `parse_sync_reason` accepts only `manual`,
`periodic` and `connection_created`, so a sweep-specific reason would fail
every Composio row with "unrecognized sync reason".
This is the secondary half of tinyhumansai#6007. The primary half — connector items never
reaching `mem_tree_chunks` — is fixed in tinymemory (tinyhumansai/tinymemory#134)
and reaches users through a module release and registry re-pin, not this change.

priority: p3
Tree ingest writes its L0 chunk rows synchronously, but the Memory Tree graph and tree-backed recall read *sealed* summaries. A buffer seals on the 50k-token `INPUT_TOKEN_BUDGET` or, failing that, on the seven-day `DEFAULT_FLUSH_AGE_SECS` force-flush — and nothing on the sync path ever asked for a seal. So a large first backfill crossed the token budget repeatedly and looked fine, while an incremental sync of a handful of messages stayed under it and those memories were invisible for up to a week, with the source row reporting them ingested the whole time. `run_sync_pass` now asks the driver to seal once a pass has written something, via `MemoryMaintenance::flush_pending()` (`max_age_secs = 0`, so every buffer is considered rather than only the stale ones). The enqueue wakes the seal worker, so the wait becomes queue-claim plus summariser latency instead of days. Placed inside `run_sync_pass` rather than at its callers because it has three of them — the budgeted loop here, the Slack trigger RPC and the sync bus — and one rule spread across call sites is exactly what caused tinyhumansai#6007. Asking once per page is affordable because the queue dedupes on `date + hour/3`: while a flush is ready/running the later pages answer `enqueued: false` and ride it. The dedupe is a partial unique index over ready/running rows only, so a completed flush leaves the index and the next enqueue succeeds — the three-hour block is the key's granularity, not a cooldown. Best-effort by construction: gated on `written > 0`, a driver serving no Maintenance is skipped, and a flush error is a warn. The records are already committed and an unsealed buffer is a delay rather than a loss, so nothing here may turn a successful sync into a failed one. Two residual behaviours are documented in the PR rather than papered over: the flush is workspace-wide, so a connector sync also seals what folder and github_repo sources left pending; and if a flush is already running when a pass commits, the suppressed enqueue leaves those items for the next sync (the periodic tick does not rescue them — it enqueues the default seven-day age).

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Preserve a follow-up flush for writes that race with an active flush.
flush_pending() deduplicates requests in a three-hour window. A flush can scan the workspace after an earlier page writes, and a later page can then write records. The later call returns enqueued: false, so no flush remains queued for those records. If no later sync occurs, they can wait for the age-based force flush.
Make the maintenance queue record a rerun when writes occur during an active or deduplicated flush. Alternatively, request the flush after the complete multi-page sync finishes.

Valid finding — this race is real, and it is called out in the PR body as the known residual gap. Not fixing it here, because neither remedy is available to the host. Tracked engine-side as tinyhumansai/tinymemory#135.
Why the host cannot close it. flush_pending() takes no arguments and the dedupe key is built inside the driver (date + hour/3), so a caller has no way to express "rerun after the in-flight scan". Worth noting the suppression is only harmful in one of its two cases: suppressed against a ready job is harmless (it has not scanned yet and will pick the new buffers up); only a running job may already have walked past the buffer.
On the suggested alternative — "request the flush after the complete multi-page sync finishes". That one is worse here, and specifically so. The pass loop has three exits, and two of them leave with more_pending: true:
next_pass_budget(...)returningNone— the per-source cap is spent (providers_ops.rs:334)passes >= MAX_PASSES— the 50-page pacing bound (providers_ops.rs:362)
Only the third exit is "the connector says it is done". So gating the flush on batch completeness would skip the seal for exactly the runs that wrote the most records — a capped 5,000-record run would ingest everything and never ask for a seal. Moving the call also does not remove the race: the critical attempt is whichever enqueue happens after the last write, and it is equally suppressible in either placement.
The remaining honest difference is that per-page can self-suppress (an earlier pages job still ready/running` when the final page tries). That is a narrower failure than dropping capped runs entirely, so per-page is the better of the two host-side options — which is why it stayed.
One correction to the finding, in your favour. It says those records "can wait for the age-based force flush", which understates it: the periodic three-hourly tick does not rescue them at all. It enqueues FlushStalePayload::default(), whose max_age_secs is None, and the handler resolves that to L0_DEFAULT_FLUSH_AGE_SECS = 604800 (seven days). So the tick steps straight over a buffer written minutes ago, and the real fallback is the next connector sync, or seven days if none comes.
Still strictly better than before this PR, where every small connector sync waited seven days. tinyhumansai/tinymemory#135 carries both candidate fixes: record a rerun when suppressed against a running job, or put the engines existing per-tree force_flush_treeon the contract (which would also fix the workspace-wide scope complaint, since a connector sync knows its ownpath_scope` and has no business sealing unrelated trees).

@YellowSnnowmann, thanks for the detailed analysis.
I agree that the host cannot close this race with the current flush_pending() contract. The driver owns both the deduplication key and the running-job state. The host cannot request a rerun after a running flush.
I also agree that moving the request to the end of the loop is not a safe replacement. A per-source cap or MAX_PASSES can end a successful run with more_pending: true. Those runs must still request a flush for records that they wrote.
The correction on the fallback is valid. A periodic stale-buffer flush does not seal a newly written buffer. The effective fallback is the next connector sync or the seven-day age threshold.
The current per-pass request remains the better host-side behavior. The remaining race requires the engine-side fix tracked in tinyhumansai/tinymemory#135. I will keep this finding open as that external follow-up.

Learning: In `src/openhuman/integrations/composio/ops/providers_ops.rs`, the host calls the bound memory driver's parameterless `Maintenance::flush_pending()` after each Composio sync pass that writes records. The driver owns the three-hour deduplication key and does not expose a way for the host to request a rerun after a running flush. A write that occurs after a running flush scans its buffer can remain unsealed until the next connector sync or the seven-day stale-buffer threshold. The required engine-side remedy is tracked in `tinyhumansai/tinymemory#135`.

Learning: For Composio sync in `src/openhuman/integrations/composio/ops/providers_ops.rs`, do not replace per-pass flush requests with a flush only after connector completion. The sync loop can end successfully with `more_pending: true` when `next_pass_budget(...)` exhausts a source cap or when it reaches `MAX_PASSES`; an end-only flush would omit those writing runs.

…pace Closes tinyhumansai/tinymemory#135, and does it host-side — that issue said the fix needed a contract addition, a release and a re-pin, and that was wrong. `MemoryTree::flush_source_tree` has been on the contract all along, is served by the pinned module, and OpenHuman already calls it from `flush_source_tree_rpc`. The swap removes the race rather than narrowing it. `flush_pending` enqueues, and that queue dedupes on `date + hour/3`, so a request landing while an earlier flush was already running was suppressed — and if that flush had walked past the buffer this pass just wrote, nothing remained queued for it. The periodic tick does not rescue those either: it enqueues the default seven-day age and steps over a buffer written minutes ago. `flush_source_tree` bypasses the queue entirely, so there is no dedupe key and nothing to be suppressed against. It also settles the second-order complaint from the tinyhumansai#6011 review: `flush_pending` is workspace-wide, so a Gmail sync sealed whatever a folder or `github_repo` source had left pending. This seals one scope. The scope is built exactly as the ingest funnel builds `path_scope` — `{toolkit}:{connection_id}`, toolkit lowercased — because it has to name the same tree the items were filed under; a drift seals nothing and reports `Ok(0)` while doing it. Calling it unconditionally is safe: the contract makes an empty scope `Ok(0)` rather than an error, and an unknown scope `Ok(0)` too. Also fixes the pin note, which claimed to have been re-read at v1.14.1 while the verification command still read `v1.13.8..v1.14.0` — a comment asserting a check it does not perform. The range now names the pinned tag, and the command was run against it: empty, so the family list still stands. Refs tinyhumansai#6012

Summary
The two host-side halves of #6007. Neither needs a module release; both are openhuman-only.
1. Apply all / sync everything never worked for a Composio source
The per-row Sync button special-cased Composio; the Apply-all sweep did not. It dispatched every enabled row through
MemorySourceSync::run_source_sync, which the driver refuses for this kind —"… is synced through the connector module, not this engine"— so "sync everything" failed for exactly the rows a user reaches for it to fix.Two call sites open-coding one rule is how they drifted, so the decision is now one pure function:
sync_dispatch(&entry) -> Result<SyncDispatch, String>, returningSyncDispatch::Connector { connection_id, max_items }orSyncDispatch::Driver. Both the row Sync button and the sweep match on it.trigger_enabled_syncs' closure now takes the wholeMemorySourceEntryrather than just the id, because routing needs the kind, the connection and the per-source cap.A second defect in the same function:
apply_all_in_rpcresolvedas_source_sync()up front and hard-errored the whole sweep when it answeredNone. For a Composio-only profile that turned Apply-all into one flat refusal over a capability none of its rows use — the same trade the row-level path already documents as a review finding on #5932. The family is now resolved as anOptionand refused per row, which is what this sweep already aggregates intosync_errors/sync_failed(#5820).Note the deliberate behaviour change: a driver serving no source sync at all now yields
sync_failed: Nwith one message per row instead of a single RPC error. That is this function's own aggregation contract.One trap worth naming: the sweep passes
manualas the sync reason, not something sweep-specific.parse_sync_reasonaccepts onlymanual,periodicandconnection_created— an invented reason would have failed every Composio row with"unrecognized sync reason", i.e. reproduced the bug through a different door.2. A synced connector item could stay invisible for up to a week
Found while answering "after the fix, will syncing Gmail actually add nodes to the memory tree?" — and the honest answer was "eventually".
Tree ingest writes its L0 chunk rows synchronously, but the Memory Tree graph and tree-backed recall read sealed summaries. A buffer seals on the 50k-token budget (
INPUT_TOKEN_BUDGET) or, failing that, on the seven-day force-flush (DEFAULT_FLUSH_AGE_SECS = 604_800) — and nothing on the sync path ever asked for a seal. So a large first backfill sealed continuously and looked fine, while an incremental sync of a handful of messages stayed under the token budget and its memories were invisible for up to a week, with the source row reporting them ingested the whole time.run_sync_passnow asks the driver to seal once a pass has written something, viaMemoryMaintenance::flush_pending()(max_age_secs = 0, so every buffer is considered rather than only the stale ones). The enqueue wakes the seal worker, so the wait becomes queue-claim plus summariser latency — seconds to a couple of minutes — instead of up to seven days.Placement notes, both deliberate:
Inside
run_sync_pass, not at its callers. It has three (the budgeted loop inproviders_ops.rs, the Slack trigger RPC, and the sync bus). One rule spread across call sites is exactly what caused Gmail/Composio sync writes docs and vectors but skips memory-tree ingest after migration #6007 — two would have got the flush and the third would have been forgotten.Per page is affordable because the engine dedupes on
date + hour/3: while a flush for the current window isready/running, later pages answerenqueued: falseand ride it. Note the dedupe is a partial unique index (idx_mem_tree_jobs_dedupe_active,WHERE status IN ('ready','running')), so a completed flush leaves the index and the next enqueue succeeds — the three-hour block is the key's granularity, not a cooldown.The one residual gap is a race rather than a schedule, and it is worth stating with its real cost: if a flush is already
runningwhen a pass's chunks land, the enqueue is suppressed, and that in-flight job may have already walked past the new buffer. Those items then wait for the next force flush. The periodic scheduler does not rescue them — it enqueuesFlushStalePayload::default(), whosemax_age_secsisNoneand resolves toL0_DEFAULT_FLUSH_AGE_SECS(7 days), so its three-hourly tick only seals genuinely stale buffers. In practice the next connector sync clears it (by then the previous job has completed and left the partial index); absent another sync, it is the seven-day flush.Closing that properly wants a per-tree seal:
force_flush_treeexists in the engine but is not on the driver contract, so reaching it means a new contract member and another module release. Follow-up, not a blocker — the race is narrow and strictly better than the pre-change behaviour, which had every small sync waiting seven days.Best-effort by construction: gated on
outcome.written > 0, a driver serving noMaintenanceis skipped with a debug line, and a flush error is a warn. The records are already committed and an unsealed buffer is a delay rather than a loss, so nothing here may turn a successful sync into a failed one.flush_pendingis not guard-wrapped, so there is no policy gate or denial path in this call.What is NOT in this PR
The primary half of #6007 — connector items writing namespace documents and vector chunks but never
mem_tree_chunks, so Gmail syncs and every tree-backed surface reports zero — is fixed in tinymemory: tinyhumansai/tinymemory#134.It cannot ride along here. This repo only dev-depends on
tinymemory-tinycortex; the production engine ships inside the prebuilt TinyBus module pinned at1.13.7insrc/openhuman/modules/registry_part_01.rs. That half reaches users through a tinymemory patch release plus a registry re-pin (which also requires bumpingARTIFACT_CAPABILITIES_PIN, orthe_capability_list_matches_the_pinned_releasegoes red). Follow-up PR once the release is cut.Half 2 does not do much for connector content until half 1 ships — before it, nothing connector-shaped is in an L0 buffer to seal. But it is not a no-op in the meantime, and that is worth being explicit about:
flush_pendingconsiders every L0 buffer in the workspace, not only the syncing source's, so a connector sync will now also seal whatever a folder orgithub_reposource has left pending. That is a scheduling side effect of using the existing engine-wide flush rather than a per-tree one (force_flush_treeis per-tree, but is not on the contract). It brings other sources' summaries forward, never drops or reorders anything — but it does mean a Composio sync now nudges unrelated trees, so flag it if that is not wanted here.So please do not close #6007 on this merge — hence
Refs, notCloses.Backfill for already-synced records is tracked separately in #6012.

composio_rows_dispatch_to_the_connector_and_everything_else_to_the_driverasserts the rule itself: a connected Composio row routes to the connector carrying its connection and cap, every other kind stays on the driver, and a connection-less Composio row is refused by name. Asserting the rule is what stops the two call sites drifting again.The post-sync flush is not unit-tested, deliberately.
run_sync_passreads the bound driver and the connector module and is not reachable from a test — the same constraint that makes the dispatch decision worth extracting as a pure function. Its observable effect is a queue enqueue inside the module. Stating that rather than implying coverage it does not have.Frontend untouched, so the pnpm lanes were not re-run.
