ADR 0006: Rename to slac

Status

Superseded by ADR 0009.

Context

The project was originally named Calibrex (calibration evidence framework). v0.2 made trajectory and odometry first-class elements: rosbag2 odometry ingestion, motion compensation, and KISS-ICP rig-frame odometry. The scope shifted from pure calibration evidence to simultaneous localization and calibration (SLAC).

At that time, the GitHub repository was renamed from rsasaki0109/Calibrex to rsasaki0109/slac. ADR 0009 later reversed this repository rename.

The name slac (lowercase) is deliberate. We are aware of the collision with SLAC National Accelerator Laboratory; this project is unrelated robotics software and uses lowercase branding to distinguish it.

The project is private, unpublished, and has no PyPI release or external users. A wholesale breaking rename is acceptable with no compatibility shims.

Decision

Rename the project to slac ("simultaneous localization and calibration"):

  • Python package: calibrex → slac (src/slac/)
  • CLI console script: calibrex → slac
  • Schema IDs: calibrex.<artifact>/vX.Y → slac.<artifact>/vX.Y
  • Provenance strings: calibrex_native, calibrex_version, and related keys → slac_native, slac_version, etc.
  • Documentation, examples, CI, and issue templates updated to match.

No deprecation aliases, import shims, or schema-version translators are provided. Configs, results, manifests, and cached artifacts must use the new identifiers.

Consequences

  • All in-tree references to Calibrex as the product name are removed except historical mentions in this ADR and an optional one-line README note.
  • Downstream forks or local clones must update imports, CLI invocations, and stored artifacts manually.
  • Schema count remains 17; only the ID prefix changes.
