v0.1.3

Thirteen changes since v0.1.2, centred on making MongoDB → GCS CDC correct for
multi-collection pipelines, plus operator notifications.

Data correctness (CDC)

• #48 — a locked destination_namespace was silently discarded on three
  destinations. A pipeline that declared and locked a destination namespace
  had its CDC rows written into the connection's database/dataset/schema
  instead. Nothing downstream can detect that: the rows land, the counts match,
  the lag is zero, and they are in the wrong place. Two independent halves, both
  fixed — the sink's document-DB CDC branch never forwarded the namespace (while
  its own batch write and reload-drop always did), and mongodb / bigquery /
  redshift accepted the parameter and ignored it. The other ten destinations were
  censused; object stores stay deliberately silent because they key by the source
  table id. Both write lanes — CDC and batch — are now guarded by mutation-proven
  tests.
• #42 — the sink derived its topic prefix by hand and subscribed to topics
  nobody writes. Self-masking, because the pre-create step then created the
  bogus topics: the pipeline reported Running / Healthy / 100% while delivering
  zero rows.
• #45 — every bronze object was written uncompressed, and a compressed parquet
  was unreadable. Billed twice over (object storage plus bytes scanned) and the
  compressed path did not round-trip.
• #39 — MongoDB → GCS CDC fixes and failure notifications.

Notifications

• #43 — admin-configured Slack and SMTP delivery, with email controls, so a
  stopped or failing pipeline reaches the team instead of sitting silent.

Deployment and self-host

• #47 — publish arm64 images, fail fast on an unreachable database, bind dev
  ports to loopback.
• #41 — the one container that resolves connectors was the one with no
  connector mount, which made no pipeline creatable on a quickstart install.
• #40 — arm64 platform pin and MinIO environment-variable fixes.

Explorer, docs and dependencies

• #46 document browse mode for MongoDB connections · #44 README leads with
  "AI-native data pipeline platform"
• #33, #50, #51 — dependency bumps (actions, pip, npm).

Upgrading

Image tags move to v0.1.3. The sink worker and the mongodb / bigquery / redshift
connector images must be pulled for the namespace fix to take effect — a pipeline
that sets no destination namespace is unaffected by it.
