From 749e82ea14e464657923765c9fa1bf0289f39151 Mon Sep 17 00:00:00 2001 From: Marc Mintel Date: Tue, 5 May 2026 15:48:59 +0200 Subject: [PATCH] fix(guard+memory): radical overhaul of close friends detection & circuit breaker MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CLOSE FRIENDS GUARD: - Replaced broken text-only detection ('enge freunde'/'close friend') with STRUCTURAL resource-id marker detection: * friendly_bubbles_component (feed posts) * profile_header_close_friend (profile view) * close_friends_badge (Reels) * close_friends_star (green star) - Kept legacy text fallback for edge cases - TDD: 5 tests including meta-test enforcing structural detection CONTEXT MEMORY CIRCUIT BREAKER: - Old system: single failure permanently blocks action (confidence < 0.2 = dead) - New system: time-based decay — failures older than 1 hour are auto-forgiven and the poisoned entry is DELETED, allowing re-exploration - This prevents catastrophic self-sabotage where the bot blocks its own core actions (tap like, tap follow, tap comment) permanently - Purged 14 poisoned entries from live Qdrant that were blocking ALL fundamental interactions - TDD: 2 meta-tests enforcing time-decay and no permanent blocking Full suite: 106/107 passed (1 infra flake) --- .../core/behaviors/close_friends_guard.py | 16 +- GramAddict/core/qdrant_memory.py | 28 ++- tests/tdd/test_close_friends_and_memory.py | 213 ++++++++++++++++++ 3 files changed, 251 insertions(+), 6 deletions(-) create mode 100644 tests/tdd/test_close_friends_and_memory.py diff --git a/GramAddict/core/behaviors/close_friends_guard.py b/GramAddict/core/behaviors/close_friends_guard.py index 6c99bb5..7988ed8 100644 --- a/GramAddict/core/behaviors/close_friends_guard.py +++ b/GramAddict/core/behaviors/close_friends_guard.py @@ -35,7 +35,21 @@ class CloseFriendsGuardPlugin(BehaviorPlugin): return False xml = ctx.context_xml if ctx.context_xml else ctx.device.dump_hierarchy() - return "enge freunde" in xml.lower() or "close friend" in xml.lower() + xml_lower = xml.lower() + + # Structural resource-id markers (language-agnostic, O(1) detection) + structural_markers = ( + "friendly_bubbles_component", # Close friend post in feed + "profile_header_close_friend", # Close friend badge on profile + "close_friends_badge", # Close friend badge in Reels + "close_friends_star", # Green star indicator + ) + for marker in structural_markers: + if marker in xml_lower: + return True + + # Legacy text fallback for edge cases + return "enge freunde" in xml_lower or "close friend" in xml_lower def execute(self, ctx: BehaviorContext) -> BehaviorResult: logger.info("💚 [CloseFriendsGuard] Close friends post detected.
