Reconnect Composio connector sync to the memory tree

[YellowSnnowmann]

Summary

The TinyCortex engine migration removed the per-provider tree-ingest half of the
connector sync (the deleted memory_sync/composio/providers/*/{source,ingest}.rs
modules that batch-ingested each synced page into the memory tree via
ingest_email). The replacement pipeline persists synced items only to the
skill-<toolkit> document store, so Gmail / Slack / Notion / GitHub / Linear /
ClickUp content stopped producing mem_tree_chunks rows and fell out of
tree-backed recall.

This reconnects tree ingestion at the Composio-only SkillDocSink seam: each
synced item is additively routed through the engine's document ingest — the same
L0-chunk path local folder sources already use via LocalDocumentSink — while
the existing skill-store write is preserved. The tree scope is
{toolkit}:{connection_id} so retrieval resolves it by platform prefix
(gmail: → email, slack: → chat, notion:/linear: → document), and each
item keeps a distinct source_id ({scope}:{document_id}) so messages admit
independently.

ingest_document writes the L0 chunk rows synchronously and enqueues the summary
seal on the async extract worker. Retrieval (query_source) reads sealed
summaries, so an item becomes retrievable once its buffer seals — on the token
threshold or the time-based flush_stale_buffers — and the seal degrades to a
fallback summary when no LLM is available.

Tree ingest is best-effort: a failure is logged and the sync continues,
leaving the skill store (which has already committed) as the source of truth.
Propagating it would let one poisonous item abort the whole connector run for the
providers that don't tolerate scope errors and re-fetch the page on every retry.

Related issue

Reconnects the tree-ingest half of tinyhumansai/openhuman#5473. (The openhuman
submodule bump that closes the issue follows once this lands on main.)

API or behavior changes

• Composio connector syncs now write mem_tree_chunks and become retrievable via
  query_source after their tree seals (restores pre-migration behavior).
• Ingested items are stamped with the ingest time (modified_at = now()),
  not the item's true source time — SkillDocument carries no uniform timestamp
  at this seam. This affects time_window_days filtering and default recency
  ordering for connector content; threading real per-item timestamps needs the
  provider/orchestrator layer and is a tracked follow-up.

Validation

Commands actually run, with their outcome — all pass:

• cargo fmt --all -- --check
• cargo clippy --all-targets --all-features -- -D warnings
• cargo build --all-targets --all-features
• cargo test --all-features

Tests

• composio_sync_document_reaches_memory_tree — ingests a synced document, then
  asserts the L0 chunks landed under the deterministic {toolkit}:{connection_id}
  scope, that query_source returns nothing before the seal, and that after
  drain_until_idle + flush_stale_buffers it is returned — proving actual
  retrievability, not just chunk existence.
• config_less_adapter_skips_memory_tree_ingest — the config-less adapter
  persists the skill document (asserted by reading skill-gmail back) without
  touching the tree.

Follow-ups (tracked separately, out of scope here)

• Versioned ingest for mutable connector docs (edited Notion pages / Linear
  issues) — depends on real per-item timestamps.
• Tree-chunk deletion symmetry: SkillDocSink::delete /
  remove_composio_source_by_connection_id should purge tree chunks via
  delete_chunks_by_source_prefix (privacy edge).
• PLATFORM_KINDS in the vendored retrieval/source.rs omits github / clickup,
  so those resolve only by exact source_id, not by kind.

Documentation

Behavior is covered by the module rustdoc and the new method's doc comment
explaining the scope-naming and seal/retrieval contract.

📝 Walkthrough

Walkthrough

The sync path now ingests configured Composio documents into the memory tree with deterministic metadata and scopes. Config-less adapters continue to store skill documents without memory-tree chunks. Regression tests cover successful retrieval and tolerated ingestion cases.

Changes

Composio memory ingestion

Layer / File(s)	Summary
Deterministic document ingestion core/src/tinycortex/sync.rs	HostSyncAdapter canonicalizes Composio documents and assigns deterministic toolkit, connection, tree, and source scopes.
Conditional storage and regression coverage core/src/tinycortex/sync.rs	SkillDocSink::store persists documents before optional memory-tree ingestion. Tests cover retrieval, queue processing, ingestion failures, blank scopes, and config-less adapters.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Mergeability Score: 🟡 Moderate · up to c97cf

Connector content is now stored in both the skill store and memory tree, but deleting a synchronized document removes only the skill-store copy; the deleted content may therefore remain available through recall. This privacy and data-lifecycle gap should be fixed or explicitly accepted before merging.

Poem

A rabbit checks each scope with care,
Then sends neat documents through the tree.
The skill store keeps every page,
Even when ingestion fails mid-stage.
Blank scopes wait quietly.
Retrieval finds the chunks in time.

Assert skill-store persistence in this test (core/src/tinycortex/sync.rs 1022–1025)

Good catch — addressed in 649218c.

The config_less_adapter_skips_memory_tree_ingest test now reads skill-gmail back after store and asserts the synced document actually persisted (exactly one document, carrying the id gmail:msg-1 and title Quarterly planning), then retains the count_chunks == 0 assertion. It proves both halves now — the skill store is written while the memory tree is untouched — rather than only the absence of tree ingestion.

Validated: cargo fmt --all -- --check, cargo clippy --all-targets --all-features -- -D warnings, and cargo test --all-features all pass.

[sanil-23]

Traced the seam through the vendored tinycortex engine (vendor/tinycortex @ be7b395). The design is right — additive routing at the SkillDocSink seam, skill-store write first, per-item source_id giving real idempotency via the document gate, and the config-less None branch correctly handled and now tested on both halves.

Two claims in the description don't hold up, plus a few gaps.

---

1. The test doesn't prove the thing this PR exists to restore

query_source — the retrieval path named as the goal — never reads mem_tree_chunks. It is a read-only view over mem_tree_trees + mem_tree_summaries, and it explicitly skips unsealed trees:

// vendor/tinycortex/src/memory/retrieval/source.rs:125-127
// An un-sealed tree (no levels, no root) has nothing to return.
if tree.max_level == 0 && tree.root_id.is_none() { continue; }
...
for level in 1..=tree.max_level { ... }

The ingest path stops at enqueue — vendor/tinycortex/src/memory/ingest/pipeline.rs:12: "the buffer append and summary seal happen in the async extract worker driven off the TreeJobSink; this hot path stops at enqueue." Leaves land in the L0 buffer; a level-1 summary exists only once should_seal fires, which at L0 requires buf.token_sum >= config.tree.input_token_budget (bucket_seal.rs:200-209).

So count_chunks() > 0 — what composio_sync_document_reaches_memory_tree asserts — does not imply the item is retrievable. A low-volume connection (a Linear workspace with a handful of issues) can sit under the seal threshold indefinitely and stay invisible to query_source. That is precisely the "ingests but is never retrievable" trap the test's own comment claims to guard against; asserting the path_scope string is a proxy for retrievability, not the property itself.

Related: "L0 chunks are written synchronously (no LLM), so tree rows land even when local AI is off" conflates chunk rows with retrievable summaries. The seal does degrade gracefully without an LLM (fallback_summary on summariser error, bucket_seal.rs:18-19), so the claim is recoverable — but the gating factor is the seal threshold, not local AI.

Ask: assert query_source actually returns the item (force a seal via seal_now / the flush path), or restate the claim in the description.

2. Propagating the ingest failure re-creates the #4947 "sync permanently stale" mode

Only Slack overrides tolerate_scope_errors() (vendor/tinycortex/src/memory/sync/composio/providers/slack.rs:221-231). For gmail / notion / github / linear / clickup the default is false, so at composio/orchestrator.rs:347-353 a store error becomes return Err(error) — the whole sync run aborts and no state is saved.

This repo already documents that exact shape as a shipped bug, in this same file's test module:

"Because gmail's tinycortex pipeline does not tolerate scope errors, one such subject would abort the entire scheduled sync with document namespace/key cannot contain secrets, leaving the source stale ('Last synced 17d ago')."
— core/src/store/client_tests.rs:120-123

This PR widens what can throw from store to the entire chunker → scorer → SQLite ingest path. One deterministically-poisonous item now stalls that connector indefinitely, re-fetching the full page (Composio actions + spend) on every retry before hitting it again.

The cited precedent isn't equivalent: the deleted item_ids_ingested outcome recorded which items succeeded, so a retry skipped them. A hard Err here discards the run's progress. And the skill-store write has already committed at that point, so the two stores diverge on failure regardless of whether the error propagates.

Ask: log-and-continue, or a bounded poison-item skip, rather than unconditional propagation.

3. Mutable connector documents are frozen at their first version

version_ms: None means the gate key is the bare source_id (pipeline.rs:315-322), and source_id is stable across re-syncs. store_skill_sync upserts on document_id, so an edited Notion page or an updated Linear issue lands in the skill store but never updates the tree — the two stores permanently diverge for anything mutable.

The seam to fix it, ingest_document_versioned's version_ms, is right there — and is unusable today only because of the next point.

4. modified_at: Utc::now() is wrong data, not just imprecise

canonicalize/document.rs:78-79 maps it straight to timestamp and time_range, which drive time_window_days filtering and the default newest-first ordering (retrieval/source.rs:88-101). Every backfilled item therefore reports "now", so a "what did I get last week" windowed query surfaces a first-sync backfill of years-old mail.

That belongs under API or behavior changes, not filed as a missing test. (SkillDocument.metadata is also dropped entirely on the tree path — if any provider stamps a timestamp there, threading it through is cheap.)

5. store and delete are now asymmetric

store writes both stores, but SkillDocSink::delete (core/src/tinycortex/sync.rs:655) still only removes the skill document — compare LocalDocumentSink::delete immediately below it, which calls delete_chunks_by_source. Nothing purges tree chunks on document deletion, nor on remove_composio_source_by_connection_id (core/src/sources/registry.rs:96, which drops the registry row only).

Consequence: content a user deleted upstream, or a connection they disconnected, stays in the memory tree and stays retrievable. delete_chunks_by_source_prefix (core/src/store/chunks/store.rs:119) already takes exactly the {toolkit}:{connection_id}: prefix this PR introduces.

6. Smaller

• GitHub and ClickUp don't resolve by kind. PLATFORM_KINDS (vendor/tinycortex/src/memory/retrieval/source.rs:199-227) covers gmail / slack / notion / linear but not github or clickup. Those scopes only match when source_kind is None or an exact source_id is passed; a kind-filtered query silently omits them. Both are listed as restored in the summary.
• source_id isn't injective. format!("{tree_scope}:{}", document.document_id) where document_id itself contains : — the test uses gmail:msg-1, yielding gmail:conn-1:gmail:msg-1. Deterministic, but ambiguous by construction. toolkit / connection_id are trimmed but not checked non-empty; an empty toolkit yields scope ":conn-1", which matches no platform prefix.
• Nit: self.config.clone() in the match clones the Arc<Config>; self.config.as_deref() avoids it and reads better.

---

1 and 2 are the ones I'd want resolved before merge — the first because the PR's success criterion is unverified, the second because it reintroduces a previously-shipped stall. 3–5 are reasonable follow-ups if you'd rather land the reconnection now, though 5 has a privacy edge worth an issue at minimum.

[YellowSnnowmann]

Thorough review — thank you. Both of the blockers were real; fixed in fd41801. Point-by-point:

① Test didn't prove retrievability — fixed. You're right: collect_source_hits walks mem_tree_trees + mem_tree_summaries and continues on max_level == 0 && root_id.is_none(), so count_chunks() > 0 proves the leaf landed, not that it's reachable. The regression test now drives the real path: ingest → drain_until_idle (append the leaf) → flush_stale_buffers (force-seal) → query_source, and asserts the item is absent before the seal and present after. So it verifies the actual success criterion, and the negative half pins the "chunks ≠ retrievable" distinction you flagged. I also corrected the description and the method doc (the seal, not local-AI, is the gating factor; it degrades to fallback_summary without an LLM).

② Propagating the failure re-created the #4947 stall — fixed. Agreed on all three sub-points: default tolerate_scope_errors() is false (only Slack overrides), so orchestrator.rs:353 turns a store error into a run-aborting Err; the deleted item_ids_ingested recorded partial progress that a hard Err discards; and the skill-store write has already committed, so propagation bought no atomicity. Tree ingest is now best-effort: store logs and continues on failure, leaving the skill store as the source of truth and the per-item source gate / operator rebuild to recover. That's the correct reading of "don't advance past un-stored items" — the item is stored (skill), the tree is a derived index.

③ Mutable docs frozen at v1 — valid, follow-up. Correct — version_ms: None keys the gate on the bare source_id, so an edited Notion page updates the skill store but never the tree. The fix is ingest_document_versioned with a real version, which is blocked on ④. Tracking as a follow-up.

④ modified_at: Utc::now() is wrong data — valid; description corrected. Moved to API/behavior changes in the description. Real per-item timestamps aren't available at this seam — SkillDocument carries no uniform timestamp and its metadata is provider-specific (gmail's is just {source, taint, message_id}) — so threading a true modified-time needs the orchestrator/provider layer. Follow-up, paired with ③.

⑤ store/delete asymmetry — valid, privacy follow-up. Real gap: SkillDocSink::delete and remove_composio_source_by_connection_id don't purge tree chunks, and delete_chunks_by_source_prefix already takes the {toolkit}:{connection_id}: prefix. One wrinkle — delete(namespace_skill_id, document_id) doesn't receive connection_id, so per-item purge needs that plumbed through (per-connection purge on disconnect is straightforward). Filing as a tracked issue given the privacy edge.

⑥ smaller:

• as_deref() over clone() — done.
• empty-toolkit/connection now short-circuits before writing an unreachable ":conn" scope — done.
• github/clickup not in PLATFORM_KINDS — correct, and I've dropped the "resolve by kind" claim for those two; they still resolve by exact source_id / None. That's a pre-existing gap in the vendored retrieval/source.rs table, so I'd rather fix it there than special-case it here — noting it as a follow-up.
• source_id non-injectivity (document_id contains :) — deterministic and only used as an opaque dedup key, never parsed back, so I've left it, but happy to switch to a delimiter that can't collide if you'd prefer.

Net: ①② are in fd41801 (full contract green — fmt, clippy --all-features, build, test --all-features); ③④⑤⑥a are tracked follow-ups. Want me to fold any of the follow-ups into this PR rather than defer?

tinysweeper/description: that finding evaluated the description as it stood at the fd41801 push, before I'd corrected it — the body now describes the best-effort log-and-continue behavior accurately (updated right after the push). Also added a test for the blank-scope guard tinysweeper/tests flagged (b501eaa). Re-review on this push should clear both.
