Stack context

Pipeline 9/12 of the Cartesian ARC arrival-v2 review. Main stack: #311 (38 levels). Optional projection: #317, outside the main tip's ancestry. Parent: codex/arc-rebuild/04-flow-clean-sample-bounds.

What and why

make ResNet ImageNet normalization explicit and opt-in

Needed / not carried forward

This level supplies the capability named above. The integrated stack has one canonical Cartesian codec, fixed independent-stream execution and model-declared decode context; it does not carry duplicate E1/legacy codecs or selectable race/joint-distance algorithms. Independent planar/simulation codecs remain outside this cleanup. No tests, fixtures or local verification scripts are committed. No training job or hardware session is launched.

Compatibility and verification

The full integration intentionally changes ARC targets: source starts at the next frame, row zero is incoming travel, and timing is measured from current proprio. Fresh compatible normalization and new experiment identities are required. Old checkpoints retain their recorded sources; same tensor width does not make them compatible. Complete experiment menus activate at the config integration level; intermediate helper PRs are not production launch candidates.

External CPU checks: 114 codec checks; 457 staged-codec checks; 93 inference/evaluator context checks; 282 open-loop oracle checks; 27 diagnostic checks; numerical post-tokenization statistics and next-frame source/preflight checks. All 325 current YAMLs resolve; 24 ARC and four baseline config-to-decoder context constructions pass. The optional projection extension passed 14 dedicated checks. These are integration receipts, not claims that every intermediate PR ran a complete training or hardware test.
