From a52e0335764de6d3c7d303d12ab64dc119bfbbea Mon Sep 17 00:00:00 2001 From: Garry Tan Date: Sun, 7 Jun 2026 09:10:27 -0700 Subject: [PATCH] feat(decision): gstack-decision-log + gstack-decision-search bins (non-interactive) Two bins mirroring gstack-learnings-* (D3A). log writes decide/--supersede/--redact/ --compact events + refreshes the bounded snapshot + enqueues for cross-machine sync; search reads the O(active) snapshot, scope-filtered to current branch, newest-first, --all to include superseded, --json for machines. Empty store returns silently (no snapshot write on an empty read).
