From a8f3c2c328a94bcbbfa69c2b5d99640a07a3f27c Mon Sep 17 00:00:00 2001 From: BaaRai <130491490+BaaRai@users.noreply.github.com> Date: Mon, 19 Oct 2026 00:32:09 +0200 Subject: [PATCH] feat(rsi): evidence-gated lesson library in shadow mode Extracts candidate lessons from terminal tasks (confirmed, negative, retest caution), gates them on cue + action + evidence, and makes extraction idempotent through a per-source evidence key. ARTEX_RSI_LESSONS selects off / shadow / inject. Shadow logs what would have been shown; inject appends a code-owned, data-not-instructions block after the planner and worker system prompts. No prompt mutation and no adoption: status stays candidate.
