Reshape the aura data namespace around one principle: every verb emits
JSON, no format flag (the headless-agent posture #264 named).
- aura data info <symbol> (new): one flat JSON object — symbol plus the
six neutral geometry fields (digits, pipSize, tickSize, lotSize,
baseAsset, quoteAsset) from DataServer::symbol_meta when the
<SYMBOL>.meta.json sidecar yields geometry; a symbol is known via bar
files OR sidecar (a sidecar-only symbol still reports its geometry);
an unknown symbol refuses with prose, exit 1. description stays out
until the neutral reader exposes it (data-server#4).
- aura data list: NDJSON — one JSON string per line; an empty archive
emits zero stdout lines, with the human affordance moved to a stderr
note in the #278 class vocabulary.
- aura data coverage: retired — #272's per-cell fault isolation subsumed
the prophylactic pre-run check; aura-runner's data_coverage_report and
its presentation helpers go with it, while interior_gap_months stays
as the campaign path's single gap walk (#295).
The three derived design decisions (description omitted, broader
refusal prose, empty-archive stderr notice) are minuted on the issue.
