/**
|
|
* gstack-decision-log — append a durable decision (or supersede/redact/compact it).
|
|
*
|
|
* Usage:
|
|
* gstack-decision-log '{"decision":"...","rationale":"...","scope":"repo","source":"user"}'
|
|
* gstack-decision-log --supersede <decision-id>
|
|
* gstack-decision-log --redact <decision-id>
|
|
* gstack-decision-log --compact
|
|
*
|
|
* Event-sourced (lib/gstack-decision): every call appends an event and refreshes the
|
|
* bounded active snapshot. NON-INTERACTIVE — never prompts (agents/skills call this;
|
|
* a prompt would hang them). Validation + injection + HIGH-secret rejection happen in
|
|
* validateDecide; a rejected decision exits 1 with a message, nothing persisted.
