/**
|
|
* bin/gstack-developer-profile — subcommand behavior tests.
|
|
*
|
|
* Covers:
|
|
* - --read (legacy /office-hours KEY: VALUE format, with defaults when no profile)
|
|
* - --migrate (idempotent; preserves sessions + signals_accumulated)
|
|
* - --derive (recomputes inferred from question-log events)
|
|
* - --trace <dim> (shows contributing events)
|
|
* - --gap (declared vs inferred)
|
|
* - --vibe (archetype match from inferred)
|
|
* - --check-mismatch (threshold behavior; requires 10+ samples)
