**Completion evidence — complete:** neutral command, binding, parse, and failure
|
||||
records now live in `internal/commandmeta`; Cobra owns only its mutable session
|
||||
and adapter logic. One cached snapshot projects sorted metadata and keys to its
|
||||
runner table. Parsing returns a snapshot-local key, and execution selects from
|
||||
that same snapshot without a second path lookup. Each invocation creates one
|
||||
session reused by parse/help/usage; presentation refreshes after registration
|
||||
without reinterpreting the original key or replaying callbacks. Core and adapter
|
||||
tests pass, including registration/help refresh, runner-key pairing, runnable
|

parents, fresh input, cancellation, and outcome delivery. No concurrency or
