Camera and lens selection needs a catalogue that includes known equipment even
when there is no Gyroflow calibration for it. This adds a generated catalogue
combining the current profile metadata and a pinned Lensfun database, and ships
it through the existing
profiles.cbor.gzrelease.Related to gyroflow/gyroflow#742. The companion
application PR #1212 reads the
reserved
__camera_databaseentry and retains an offline fallback for olderbundles. Existing clients already ignore reserved entries.

supplied. Per-profile video crop factors are not used as sensor measurements.
and tooling fixtures from the calibration bundle.
CC BY-SA 3.0. Existing Gyroflow profiles retain their CC0 licence.
Validation: all five generator tests pass, regeneration matches the committed
JSON, and the production compressor produced a verified bundle containing
9,810 calibration/preset entries plus the version and catalogue metadata. The
companion app successfully loads this bundle.
Lensfun is used here for catalogue metadata. This does not import Lensfun
distortion models as Gyroflow calibrations.
AI and third-party material disclosure: the generator, tests and integration were
produced with OpenAI Codex assistance, then reviewed and tested in that coding
workflow. The catalogue contains third-party Gyroflow profile metadata (CC0) and
Lensfun data (CC BY-SA 3.0); the sources, pinned revision and data licence are
identified in the JSON and CAMERA_DATABASE.md. Those source data are not claimed
as original authorship by this contributor.
