Raven is licensed under the Apache License 2.0. It incorporates code from the following MIT-licensed projects. Their copyright notices and license texts are retained in LICENSES/.

nanobot (base agent runtime)

• Source: https://github.com/HKUDS/nanobot
• Copyright (c) 2025 nanobot contributors
• License: MIT — see LICENSES/MIT-nanobot.txt
• Scope: forked at v0.1.5.post3; modified throughout raven/ (agent/, bus/, channels/, cli/, config/, cron/, providers/, session/, skills/, templates/, utils/).

hermes-agent (TUI layer)

• Source: https://github.com/NousResearch/hermes-agent
• Copyright (c) 2025 Nous Research
• License: MIT — see LICENSES/MIT-hermes-agent.txt
• Vendored at commit: dd0923bb89ed2dd56f82cb63656a1323f6f42e6f (2026-05-12)
• Scope: full ui-tui/ import (169 files / ~31.6k LOC TypeScript src
  • ~26.3k LOC vendored @hermes/ink). Modifications: branding replaced with minimal Raven component, gateway stubbed (no real IPC; deferred to tui-ipc-bridge L2), 36+ env vars renamed HERMES_* → RAVEN_*, literal Hermes/Nous brand strings replaced throughout ui-tui/src/, SPDX/Copyright headers added to every ≥ 50 LOC source file.

ink (vendored via @hermes/ink)

• Upstream source: https://github.com/vadimdemedes/ink
• Copyright (c) Vadym Demedes, Sindre Sorhus, and ink contributors
• License: MIT — see LICENSES/MIT-ink.txt
• Scope: hermes-agent ships its own fork of community ink at ui-tui/packages/hermes-ink/ (~26.3k LOC). Raven inherits this vendor verbatim (package name @hermes/ink preserved for attribution). Triple attribution chain (ink contributors → Nous Research hermes-ink → EverMind modifications) is encoded in the 5-line SPDX header of every substantial file under ui-tui/packages/hermes-ink/src/. Re-evaluation triggers (Nous halts maintenance / severe CVE / community ink converges / patch debt > 500 LOC) are recorded in docs/RepoMem/temp/tui-fork-hermes-import/02-hermes-ink-vendor-vs-community.md (to be promoted to docs/RepoMem/persist/architecture/hermes-fork-strategy.md at L2 archive time).

External Runtime Tools (not vendored)

The following tools are invoked by Raven via subprocess calls but are not bundled or redistributed as part of any Raven release artifact. Their attribution here is supply-chain hygiene, not a license requirement. Users install them separately through their respective package managers.

tui-use (TUI autotest harness Tier 1 backend)

• Source: https://github.com/onesuper/tui-use
• Copyright (c) 2026 Wei Hong (onesuper)
• License: MIT
• Install: npm install -g tui-use (npm package tui-use)
• Scope: invoked by tests/tui/autotest/runner.py::Harness for PTY-driven TUI subprocess control. Selected as Tier 1 backend per Day 0 spike (2026-05-20) — all 5 acceptance gates S1-S5 passed. Raven does NOT vendor, redistribute, or modify tui-use source.
• Fallback contingency: if upstream maintenance halts (>90 days no push) or a severe incompatibility surfaces, the L0-L3 ladder in docs/RepoMem/temp/tui-auto-test/tier1-backend-comparison.md defines the vendor-or-pivot strategy. Vendoring (path L1) would require moving tui-use to vendor/tui-use/ and adding its LICENSE to LICENSES/ plus updating this section's "Scope" line to "vendored" — same pattern as hermes-agent above.
