From 018b615829be239193720d0fd52ff07d71d99d0d Mon Sep 17 00:00:00 2001 From: Marc Mintel Date: Fri, 24 Apr 2026 22:45:48 +0200 Subject: [PATCH] =?UTF-8?q?fix:=20systemic=20GOAP=20self-sabotage=20?= =?UTF-8?q?=E2=80=94=20SSOT=20consolidation=20+=20step-aware=20validation?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ROOT CAUSE: The bot was systematically sabotaging its own navigation. The HD Map planned correct 2-step routes (Home→Profile→FollowList), but _execute_action() validated each INTERMEDIATE step against the FINAL goal. Step 1 (tap profile tab → OWN_PROFILE) got rejected because the goal said 'following', triggering aversive learning that permanently burned the only valid route. SIX COMPOUNDING FIXES: 1. SSOT Consolidation (_is_goal_achieved): Replaced 12-line hardcoded if-chain with ScreenTopology.goal_to_target_screen(). Single source of truth for all goal→screen mappings. 2. Step-Aware Navigation Validation (_execute_action): Replaced goal_screen_map keyword-scan with ScreenTopology.expected_screen_for_action(action, pre_action_screen). Now validates: 'did this step land where IT should?' not 'did I reach my goal yet?' 3. Topology Guard (aversive learning): ScreenTopology.is_structural_action() prevents burning HD Map actions. VLM may fail to find the element, but the route itself is structurally valid. 4. Fast-Path Threshold Fix (telepathic_engine): 100% match threshold now applies only to NAV_TAB_KEYWORDS (actual tabs), not NAV_ZONE_BYPASS_KEYWORDS. 'tap following list' was blocked because 'following' triggered the tab threshold on a non-tab action. 5. navigate_to_screen SSOT: Replaced 8-entry goal_map dict with ScreenTopology.screen_name_to_goal(). 6. QNavGraph Name Map Dedup: Replaced 2 inline screen_name_map/name_to_screen dicts with ScreenTopology.SCREEN_NAME_MAP reverse lookups. Before: 4 competing goal→screen mappings. Self-sabotage loop. After: 1 SSOT. Step-aware validation. Topology-protected routing. 141 unit tests pass. Zero regressions. --- GramAddict/core/goap.py | 132 ++++++++++-------------- GramAddict/core/q_nav_graph.py | 29 +----- GramAddict/core/screen_topology.py | 59 +++++++++++ GramAddict/core/telepathic_engine.py | 7 +- tests/unit/test_goap_step_validation.py | 116 +++++++++++++++++++++ tests/unit/test_screen_topology.py | 80 ++++++++++++++ 6 files changed, 320 insertions(+), 103 deletions(-) create mode 100644 tests/unit/test_goap_step_validation.py diff --git a/GramAddict/core/goap.py b/GramAddict/core/goap.py index 8f7cae1..43767aa 100644 --- a/GramAddict/core/goap.py +++ b/GramAddict/core/goap.py @@ -725,29 +725,22 @@ class GoalPlanner: return "force start instagram" def _is_goal_achieved(self, goal: str, screen_type: ScreenType, context: dict) -> bool: - """Check if the goal is already satisfied.""" + """Check if the goal is already satisfied.
