From 5b56c66bb5ff7b817662ed142528d3fb694d1671 Mon Sep 17 00:00:00 2001 From: anti Date: Wed, 17 Jun 2026 16:57:21 -0400 Subject: [PATCH] docs(1.1): measured batch-group RAM delta (-350MB / ~70%) 4 live batch workers = 509MB; consolidated startup floor = 118.5MB (imports 102.5 + repo pool 15.7 once vs 4x + bus 0.3). Side-effect-free measurement (no mutation tick). Floor is a lower bound; live adds modest per-worker working set. Exact live number pending controlled unit swap. --- development/RELEASE-1.1.md | 26 +++++++++++++++++++++----- 1 file changed, 21 insertions(+), 5 deletions(-) diff --git a/development/RELEASE-1.1.md b/development/RELEASE-1.1.md index 6b0ee3d2..d32f6cf8 100644 --- a/development/RELEASE-1.1.md +++ b/development/RELEASE-1.1.md @@ -170,9 +170,25 @@ B is incremental, reversible, and keeps the ops model you know — it de-risks t pattern on one group before betting the fleet.
