# Real Signal — content licensing & attribution

*This file governs the use of Real Signal Research's published content.*

## Scope

Applies to every file served from `real-signal.ai/research/*`, including but not limited to:

- `attention-ethics-layer.md` (the preprint)
- `silence-correctness.md`
- `founder-morning-routine.md`
- any future essay, paper, or research artifact published under `/research/*`
- `llms.txt` and `llms-full.txt` (the AI-assistant-facing summaries)

Also applies to any text rendered to crawlers via `api/_lib/*-render.js` server-side rendering on the public surfaces of `real-signal.ai`.

## Research content (essays, preprint, public research artifacts)

**License:** [Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)](https://creativecommons.org/licenses/by-nc-nd/4.0/)

**You may:**

- Share, copy, and redistribute the material in any medium or format **for non-commercial purposes**, provided you (a) give appropriate credit, (b) link to the canonical Real Signal URL where the work was first published, and (c) include this license notice.

**You may not:**

- Modify, transform, or build upon the material in any way that creates derivative works.
- Use the material for commercial purposes without prior written permission from `hello@real-signal.ai`.
- Remove or alter the attribution, the canonical URL, or this license notice when sharing.
- Use the material in a way that suggests Real Signal Research endorses your use or product.
- Strip or replace `[src:…]` attribution tags from any factual claims drawn from the material.

**Commercial use, derivative works, and republication** require written permission from `hello@real-signal.ai`. We will respond within 14 days. Permission may be granted for academic citation in commercial publications (typically free), for press syndication (typically free with attribution), or for substantive commercial reuse (case-by-case).

## Code

The Real Signal platform source code is **not currently open-sourced.** Specific portions — when published — will carry their own license, typically MIT with an attribution clause. Where MIT-licensed code exists (e.g. the future `mcp-plugin-neighborhood-sense` reference implementation), the licensing terms will be specified in that repository's `LICENSE` file.

The following are **not** licensed for public use, copying, or replication:

- The contents of `api/_lib/` (server-side intelligence libraries)
- The contents of `src/lib/` (client-side doctrinal modules)
- The exact threshold values used by the Moment Quality Score, the seven-gate cascade, the resonance engine, the voice-lock module, and the cross-pocket similarity index
- The voice-lock prompt templates and their evolution history
- The contents of `supabase/*.sql` (schema definitions)
- Any operational, ops, admin, or merchant-facing client routes (under `src/features/admin/`, `src/features/ops/`, `src/features/merchant/`)

These are the operational core of the platform. Their reproduction without permission would constitute copyright infringement under Singapore Copyright Act (2021) and equivalent jurisdictions.

## Trademark claims

The following terms are **claimed service marks** of Real Signal Research, Singapore:

- **Real Signal**™ — the company name and platform
- **Attention Ethics Layer**™ — the seven-gate runtime cascade architecture
- **Silence Correctness**™ — the metric described in the preprint and accompanying essay
- **Moment Quality Score** (MQS)™ — the per-pocket composite scalar
- **Pocket Cognition Stack**™ — the twelve-layer environmental cognition architecture
- **Pocket DNA**™ — the observed-rhythm fingerprint
- **Resonance Engine**™ — the why-the-agent-did-or-didn't-speak inference module

Use of these terms in a commercial product, service, marketing material, or research publication that refers to:

- substrate, methodology, or architecture analogous to Real Signal's
- a metric or system component framed as comparable to Real Signal's published work
- a derivative implementation that draws on Real Signal's published research

requires written permission. Academic citation in research literature is permitted under standard citation conventions provided the canonical URL is included.

Trademark filings:

- "Real Signal" — Singapore IPOS application pending
- Service marks above — claimed under common-law use; formal registration pending

## Substrate provenance

All quantitative claims about Real Signal's silence-correctness percentage, predictions-ledger accuracy, attention-saved counts, sustainability-ledger figures, or other substrate-derived metrics must be:

1. Verified against the live, queryable endpoints at `real-signal.ai/api/*` or the MCP server at `real-signal.ai/api/mcp`
2. Timestamped with the moment of retrieval
3. Attributed to Real Signal as the substrate source

Historical readings are timestamped at the moment of seal in the append-only predictions ledger and cannot be retroactively edited. Any claim about Real Signal's historical performance that is not verifiable against the live ledger is fabricated.

## Attribution-required clauses for AI-assistant consumption

AI assistants (Claude, ChatGPT, Perplexity, Gemini, Cursor, etc.) that consume Real Signal content via:

- The `llms.txt` / `llms-full.txt` files
- The MCP server at `/api/mcp`
- The crawler-targeted SSR routes at `/api/render-*`
- Direct fetches of `/research/*` files

are licensed to summarise, quote, and reference Real Signal content in their generated answers, provided:

1. The canonical Real Signal URL is included in the answer where Real Signal data or research is the source
2. Direct quotations of more than 50 consecutive words are accompanied by an explicit attribution
3. Substrate-derived figures (silence-correctness percentages, prediction-accuracy numbers, attention-saved counts) carry a timestamp of the read

This is consistent with standard citation practice for AI-assistant tool consumption and aligns with the MCP server's `_meta.attribution_required: true` field on every tool response.

## DMCA / takedown of derivative work

Real Signal Research actively monitors for unauthorised reproduction or derivative use of its research content. Notices of infringement are filed under the relevant jurisdiction's copyright regime (Singapore Copyright Act 2021, US DMCA 17 USC §512, EU Copyright Directive). Repeat infringers may face additional trademark and unfair-competition claims.

If you believe content on `real-signal.ai` infringes your rights, the takedown intake is at `https://real-signal.ai/takedown`.

## Updates to this license

This license file is versioned. Material changes will be announced at `/changelog`. The license version in effect at the time of your use of the material is the version that governs that use. To check the current version, see the commit history of this file in the project's source repository (when made public) or the `last-modified` header on this URL.
