 calib.jsonl — 10M tokens of agent-shaped RAW text (45% code, 30% prose,
 25% tool-call JSON), one {"prompt": text} per line, pushed to

+local material is only ~1.6M unique tokens; MOE-W4 wants 10M):
+nampdn-ai/tiny-codes (code) and Salesforce/wikitext wikitext-103-raw

+repo's own scripts plus a fleet-ops set, with argument-shaped variants.
