Closes #3396.

Why. The connector's accounts were invisible to identity resolution. An account was attributable only when some other connector happened to report the exact same address, and POST /v1/resolution/bind could not reach it either — person_map inner-joins identity_inputs with account_assignment, and this connector wrote no rows.

What changed. The chain every identity-producing connector already uses: snapshot → fields-history → identity_inputs tagged silver:identity_inputs, registered in the shared union. A flattening ReplacingMergeTree projection precedes it because the members stream carries the account as a serialized object, which neither macro can reach by name.

Read through toString + JSONExtractString, not subfield access. Installations differ in how the destination types that object — it may be String or JSON — and subfield access compiles only against the latter, so it is not a portable way to read it.

Rows without an account uuid are dropped, rows without an email are kept. That uuid keys the rest of the chain, and an empty one would travel as a real entity. A missing address costs only automatic matching: the account stays bindable by hand.

Not a roster emitter — deliberate. No roster_membership, no person profile claims: the connector observes accounts, it does not assert who exists. One macro argument away if that changes.

No deactivation_condition. The only seat-state columns the stream carries are re-asserted on every read, so a condition over them would emit DELETE rows for every identity field of an account the vendor merely re-described.

One model covers every configured instance: insight_source_id derives from the bronze row, not from a variable. The shared union goes from 13 contributors to 14.

Out of scope. Account-keyed attribution for AI metrics — gold/ai_metric_evidence.sql emits empty account columns and the class contract carries no account id, so resolution stays email-keyed. Not tracked yet; it needs a class-contract column and a numbered migration. Also out of scope: the lower vs lower + trim split between the seed and person_map, which is an identity-resolution defect unrelated to this connector.

Verified. dbt parse on the pinned toolchain (dbt-core 1.11.14, dbt-clickhouse 1.10.2): clean, no new deprecations; the manifest carries the four models with the expected tags and the union's new edge. The extraction expression was exercised against both representations of the column on a real ClickHouse — on the JSON form it returns values identical to subfield access, and on the String form it reads correctly, including a record with no email, one with no uuid, and a null object. The connectors-ddl job builds the warehouse from the DDL snapshot and runs the models against it; that is the gate for the warehouse behaviour.

📝 Walkthrough

Walkthrough

The Claude Team connector now flattens member accounts, tracks identity field history, and emits identity observations through new staging models. The connector version and shared dbt dependency declaration are updated.

Field history feeds the incremental identity-input model. The model emits email, display_name, and the canonical id binding row. The shared model declares the dbt dependency.
Connector declaration

The connector version changes to 3.4.0, with documentation for the identity-observer pipeline and bindings.

The connector did not contribute to identity_inputs, so its accounts were
invisible to identity resolution: a Claude account was attributable only
when another connector happened to report the exact same address, and
POST /v1/resolution/bind had nothing to match either, since person_map
inner-joins identity_inputs with account_assignment.

Adds the standard chain every identity-producing connector already uses.
The members stream carries the account as a serialized object, which
neither the snapshot macro (hashes named columns) nor fields_history
(tracks by name) can reach, so a flattening ReplacingMergeTree projection
precedes the snapshot.

Installations differ in how the destination represents that object, which
may be typed String or JSON, so the projection reads it through toString
plus JSONExtractString rather than subfield access: the former is correct
for both, the latter compiles only against JSON. The projection also drops
rows carrying no account uuid, since that uuid keys the rest of the chain
and an empty one would travel as a real entity; rows carrying no email are
kept, as the account stays bindable by hand.

identity_inputs contributes email and display_name plus the ADR-0002 id
binding row under source_type claude-team, and is registered in the shared
union, whose depends_on edges dbt cannot infer from the tag alone.

The connector stays an observation producer: no roster_membership and no
person profile claims, so it does not assert who exists.

A single model covers every configured instance — insight_source_id is
derived from the bronze row, not from a variable. No migration ships with
it: the staging relations are new, so dbt creates rather than alters them.
No backfill either — snapshot stamps _tracked_at at build time, which the
union's incremental watermark admits.
