``verified: true`` may also be set by an automated operator (a service) that
attests machine-verified geometry: stability-gated detector boxes inside sane
caps. The restoration pipeline consumes box/script geometry only - the ``text``
field is advisory metadata and never reaches the pixels - so what verification
must guarantee is the geometry, and a machine gate can.
``verified: true`` may also be set by an automated operator that attests

operators should use the geometry-only schema 2, which carries no transcription
or script metadata.

The manifest is a JSON object with `schema_version: 1`, `verified: true`, decoded
RGB dimensions, `source_pixel_sha256`, and a non-empty `lines` array. Each line has
an integer `[x1, y1, x2, y2]` box, exact `text`, a non-empty `script`, and an optional
angle from -30 to 30 degrees. Lines must be in top-to-bottom, left-to-right order.
The manifest is a JSON object with `verified: true`, decoded RGB dimensions,
`source_pixel_sha256`, and a non-empty `lines` array. Schema 1 is retained for
manually reviewed annotations: each line has an integer `[x1, y1, x2, y2]` box,
exact `text`, a non-empty `script`, and an optional angle from -30 to 30 degrees.
Schema 2 is geometry-only: each line has the box and optional angle, with no
required `text` or `script`. Lines must be in top-to-bottom, left-to-right order.
The hash binds the annotations to decoded RGB geometry and pixels, so metadata-only
container changes remain valid while a resized or edited source fails closed. The
