Design

Goal

Improve the first-party polyfill fleet's usefulness while preserving provenance honesty. This change is not about making every connector broad; it is about adding streams that materially improve assistant/demo value and can be verified against real owner data or clearly marked unavailable.

Sequencing

Start with connectors that do not require hostile browser automation or new upstream accounts. Local-file connectors and API-backed connectors should generally precede bank/browser connectors. Browser-only streams should require a reproducible live-smoke note before being marked done.

Provenance Rule

Spotify and Reddit are special because local rows have previously been populated by fixture/demo paths. Those rows must not be presented as Tim-account evidence. The implementation must either purge and re-ingest real owner data, or label the connector as blocked/untrusted until real-account ingestion is possible.

Non-Goals

• No new public API surface.
• No fixture-redaction pipeline; that is add-connector-fixture-scrubber-pipeline.
• No partial-run semantics; that is define-partial-run-honesty.
• No runtime scheduler/control-plane redesign.

Acceptance Checks

• Every added stream has manifest schema, parser coverage, and at least one integration-style test.
• Every live-smoke claim distinguishes real owner data from fixture/demo data.
• Spotify/Reddit fake-data cleanup is either completed or visibly tracked as blocked before internal demo evidence is generated from those connectors.
