Reviewer's GuideThe PR fixes propagated WHOOP/Peloton grouping by introducing shared provenance-plus-UUID identity evidence across PostgreSQL and ClickHouse, then uses that identity to propagate authoritative origin deletion while retaining raw records and protecting tombstone evidence from stale downstream updates. It includes schema migrations, read-model updates, comprehensive lifecycle regressions, and rollout documentation. Sequence diagram for WHOOP identity matching and activity groupingsequenceDiagram

**Late copy escapes origin deletion**
When a WHOOP deletion event arrives before the matching Peloton copy is inserted, while the WHOOP origin row has never been imported, `markProviderActivityAbsent` updates only matching rows that already exist, so a Peloton copy inserted afterward has no stored WHOOP absence evidence. Peloton reconciliation cannot infer deletion when the WHOOP row was never imported, and the copy remains visible.
Persist confirmed origin deletions by identity, or otherwise ensure a later copy upsert/reconciliation can discover and apply the deletion evidence.
Also at `src/db/provider-activity-absence.ts:164-180`.

</code_context>
<issue_to_address>
**Old workers can restore deleted copies**
When pre-PR workers are still handling provider syncs or present events after the migration is applied, a pre-PR worker handling a downstream present event or list sync clears `provider_absent_at` without checking the origin tombstone, so the Peloton copy becomes visible during the rolling deployment. The additive migration adds no database guard, and a copy whose origin was never imported stays visible until a later WHOOP reconciliation.
Drain or pause old workers before enabling downstream event processing during rollout, or enforce the origin-tombstone check in the database so old binaries cannot clear it.
Also at `src/db/provider-activity-absence.ts:160`.

+ )`;
+}
</code_context>
<issue_to_address>
**Late origin import clears deletion evidence**
When a WHOOP deletion tombstones a copy before its origin row is imported, then a later sync imports that origin as active and Peloton reports the copy present, `originAllowsRestoreSql()` allows restoration whenever it finds an imported origin with neither tombstone set, even when the copy’s `absence_provider_id` records a prior WHOOP deletion. A later Peloton-present sync then clears the copy’s tombstone although no authoritative WHOOP-present result confirmed the origin’s return.
Preserve confirmed origin-deletion evidence independently of whether an origin row is later imported, and clear it only after authoritative confirmation that the origin is present.
</issue_to_address>
### Comment 4

</code_context>
<issue_to_address>
**Stale sync revives deleted origin**
When a WHOOP list fetch includes a workout, then a WHOOP deletion event tombstones it, and the older list sync finishes afterward, an older WHOOP list sync that fetched the workout before deletion clears the origin row’s tombstone when it finishes after `markProviderActivityAbsent`; the following `linked_copies` query then sees an active origin and leaves the origin visible while its Peloton copy remains tombstoned. The activity state no longer reflects the confirmed deletion.
Serialize per-user/provider sync and deletion reconciliation, or version absence evidence so a list fetched before a deletion cannot clear its tombstone.
</issue_to_address>
### Comment 5

+ (SELECT absence_provider_id FROM linked_copies WHERE id = candidate.id),
+ ${reconciliation.providerId}
+ )
</code_context>
<issue_to_address>
**Reconciliation aborts on duplicate IDs**
When multiple WHOOP rows have external IDs that normalize to the same UUID and a linked copy is reconciled, `linked_copies` returns multiple rows for one candidate, so the scalar subquery in the update raises a cardinality error and reconciliation fails, leaving absence state unreconciled.
Make the `linked_copies` result unique per candidate before using it in the scalar subquery.
</issue_to_address>Sourcery assessment
Needs a human reviewer. 5 findings to address first, and if an exact WHOOP-origin match is wrong, or an authoritative absence is misreported, reconciliation can change persisted group IDs or tombstone a Peloton copy so it disappears from activity views. The raw rows are retained and later sync/reconciliation can repair this, but reverting the code alone does not undo stored tombstones or group changes.
Blocking findings: src/db/provider-activity-absence.ts:225, src/db/provider-activity-absence.ts:249, src/db/provider-activity-absence.ts:73, src/db/provider-activity-absence.ts:160, src/db/provider-activity-absence.ts:187

 [Medium impact] The PR appears safe to merge; no actionable correctness or repository-rule issues remain. SummaryThe PR links WHOOP workouts to identified Peloton copies without relying on matching times or categories.
No new actionable issues found. The earlier reported issues are addressed. This review checked code and tests; it did not run them.

WHOOP workouts propagated to Peloton can appear as separate activities when WHOOP changes their timing or Peloton assigns a broader category. Deleting the WHOOP workout can also leave its Peloton copy visible. Match explicit WHOOP provenance and UUIDs independently of timing/category, and use the same evidence in PostgreSQL and ClickHouse origin selection.
Propagate authoritative origin absence to identified copies, including copies whose original row was never imported. Record the confirming provider so stale downstream lists cannot erase origin-deletion evidence. Restoration requires authoritative upstream presence followed by downstream presence. Source restoration and absence share an identity predicate, so duplicate upstream UUID spellings return together when explicit same-user/provider copy evidence proves their equivalence; unrelated opaque IDs retain exact matching. Raw records and original activity categories are preserved. Missing copy-provider hints are nullable.
Includes PostgreSQL migration 0158, pre-CDC ClickHouse migration 0105, current-schema fixtures, regression tests, and rollout guidance. One user-approved Squawk exception covers only the inline foreign key on a new nullable column without a default; PostgreSQL skips its historical validation scan and immediately validates the constraint.
Merge verification also exposed a pre-existing training-load date-loop bug at 02:30 in a daylight-saving timezone. Advance dates in UTC to match the existing UTC labels, with a pinned-clock regression asserting both endpoints. ClickHouse migration placement matches fresh tables, with a real positional-copy regression preserving tombstone and group fields.
Validation:
All four hosted integration shards also pass after the final fixes. Broader local router fixtures reach the documented ClickHouse memory cap even with one worker; hosted CI verified those suites. The full local analytics build stops before dbt because the fresh workspace has no application ingest database. Production has not been changed; deploy the migrations through the normal workflow, then verify a completed authoritative WHOOP sync, mirrored identities/tombstones, and downstream read models/caches.
