ARH — AI Research Helper
========================

Copyright (c) 2025-2026 ARH Contributors
Licensed under the MIT License — see LICENSE.

This product is a derivative work in spirit but NOT in code: the
implementation was written from scratch in Python by ARH Contributors.
Where ARH borrows DESIGN IDEAS (architectural patterns, interface
shapes, naming conventions) from existing open-source agent frameworks,
the relevant inspirations and their original copyright notices are
acknowledged below as a courtesy and to honor MIT-style attribution
requirements where applicable.

No upstream source files have been copied, vendored, or transcribed
verbatim into this repository.

Design-pattern inspirations
────────────────────────────────────────────────────────────────────

1) hermes-agent  (MIT)
   Copyright (c) 2025 Nous Research
   Source: https://github.com/NousResearch/hermes-agent
   Inspiration scope:
     - Session reflection / L2 summary cadence
     - skill_manager extraction & approval flow
     - PermissionMode (default / plan / acceptEdits / yolo)
     - OpenRouter catalog integration shape
     - Multi-handler logging (arh.log / errors.log)

2) OpenClaw  (MIT)
   Copyright (c) 2025 Peter Steinberger
   Source: https://github.com/openclaw/openclaw
   Inspiration scope:
     - Hub-Spoke Gateway architecture
     - AgentRuntime layering (request → policy → tool → response)
     - ToolRegistry + ToolPolicy separation
     - AllowList / ApprovalGate security model
     - state-dir runtime config (data/llm_state/runtime.json)

3) Nanobot  (MIT)
   Copyright (c) 2025-present Xubin Ren and the nanobot contributors
   Source: https://github.com/HKUDS/nanobot
   Inspiration scope:
     - AgentRunner main loop shape
     - Consolidator post-processing pattern

4) OpenHarness  (MIT)
   Copyright (c) 2025 OpenHarness Contributors
   Source: https://github.com/HKUDS/OpenHarness
   Inspiration scope:
     - run_query while-loop pattern
     - AutoCompactState threshold logic
     - Streaming timeout strategy (first-chunk + idle + hard deadline)

5) AstrBot  (AGPL-3.0) — IDEAS ONLY, NO CODE
   Copyright (c) AstrBotDevs
   Source: https://github.com/AstrBotDevs/AstrBot
   Inspiration scope (general patterns observed in public docs only):
     - Multi-platform chat adapter convention names
     - SQLite WAL mode for concurrent reads
     - Configuration integrity check pattern
   Important: ARH contains NO AstrBot source code, vendored modules,
   or transcribed snippets. Only public-domain design conventions
   (e.g. enabling SQLite `PRAGMA journal_mode=WAL`) and high-level
   architectural ideas are referenced. AstrBot's AGPL-3.0 obligations
   therefore do not apply to ARH; if a future patch would actually
   copy AstrBot code, that patch MUST be rejected (or ARH must
   relicense to AGPL-3.0).

How to report a misattribution
────────────────────────────────────────────────────────────────────

If you maintain one of the projects above and believe ARH actually
copied your source (rather than merely borrowing ideas), please open
an issue at https://github.com/LiRunGuo/Arhelper/issues with the
specific file/line pair so we can either remove the offending code
or formally inherit your license.
