-- Ingest-token write provenance.

|
|
-- The `measurements:write` Bearer scope mints a token a home-automation
|
|
-- bridge pastes into a rule; until now the rows it pushed were attributed
|
|
-- `MANUAL`, the same label a hand-typed reading gets, so afterwards nobody
|
|
-- could tell which readings came off the scale. Rows written under that
|
|
-- scope carry their own `MeasurementSource` value instead, so they are
|
|
-- distinguishable from MANUAL / TELEGRAM / MCP provenance and get an
|
|
-- isolated idempotency namespace `(userId, type, EXTERNAL, externalId)`.
|
|
--
|
|
-- Purely-additive enum extension; no row touched. `ADD VALUE IF NOT EXISTS`
|
|
-- makes a rerun safe. The new value is NOT used elsewhere in this migration,
|
|
-- so it is safe to extend the enum in the same step (Postgres only forbids
|
|
-- USING a freshly-added value in the same transaction). Mirrors the 0189
|
|
-- extension that added TELEGRAM and the 0207 one that added MCP. The enum is
|
|
-- `@@map`-ed to the snake_case type name `measurement_source`.
|
|
--
|
|
-- No backfill, deliberately, and none is possible: `measurements` carries no
|
|
-- actor or token column and the audit trail never records the credential, so
|
|
-- a bridge-written MANUAL row is byte-identical to a hand-typed one. That
|
|
-- indistinguishability is the bug being fixed; any heuristic would relabel
|
|
-- real hand entries as machine ones. Existing rows stay MANUAL — still
|
|
-- editable, and correctly not badged.
|
|
--
|
|
-- Reversibility: Postgres cannot remove an enum value, so `EXTERNAL` stays
|
|
-- (inert with no rows).
