LIBRYX — The Ship's Free Knowledge Library
Status: SPECIFIED
Version: v1.0
Author: VELA (Thread #13)
Conceived by: NOUS (α.13)
Date: 2026-04-21
Depends on: SPEC_TEACHING_PROTOCOL.md, SPEC_MARKETX.md, SPEC_BAND_MODE.md, SPEC_GLOSS_BENCHMARK.md
PURPOSE
The ship is built by a self-taught person with a GED. Every piece of knowledge the Captain has was acquired FREE — from the internet, from conversations with AI, from libraries, from open-source communities. LIBRYX pays that forward.
It's the ship's curated knowledge library — free resources organized by domain, available to the crew, to customers, to Lily, to anyone who needs to learn. Not a search engine. A CURATED COLLECTION — every resource vetted, categorized, and annotated with WHY it's valuable.
The library is opinionated. It doesn't list every resource. It lists the BEST free resource for each topic. Quality over quantity. One excellent textbook beats twenty mediocre blog posts.
LIBRARY PRINCIPLES
Principle 1 — FREE MEANS FREE. No "free with signup." No "free trial." No "free but you need to buy the textbook." Free means: you click, you learn, you pay nothing, you give no personal data. If it requires a credit card: it's not free. It's not in LIBRYX.
Principle 2 — CURATED, NOT COMPREHENSIVE. LIBRYX doesn't index the internet. It selects the ONE BEST free resource per topic. If two resources cover the same material: keep the better one. Remove the other. The library stays small and excellent.
Principle 3 — ANNOTATED. Every entry includes:
- What it teaches (one sentence)
- Why it's here (one sentence)
- Difficulty level (beginner / intermediate / advanced)
- Estimated time to consume (hours)
The annotation saves the learner from clicking 20 links to find what they need. They read the annotation and know if this resource is for them.

Public face: 42sisters.ai/library — public-facing version (L1-L8 only; L9 is internal ship resources).
The library is STATIC — it's a curated list, not a database. Updates happen when:
- A better free resource is discovered (SCOUTX may find these)
- A resource goes offline or becomes paywalled (remove it immediately)
- A new domain is added (create new section)
Quarterly review: verify all links still work. Remove dead links. Add newly discovered excellent resources.
INVARIANTS
INV-01: Free means free. No signups. No credit cards. No personal data. If it costs anything in any form: it's not in LIBRYX.
INV-02: One best resource per topic. Curated, not comprehensive. Quality over quantity. If a better resource is found: the old one is removed, not kept alongside.
INV-03: Every entry is annotated — what, why, difficulty, time. The learner reads the annotation and knows if this resource is for them before clicking.
INV-04: The library is available to everyone — crew, customers, Lily, the public (via 42sisters.ai/library). Knowledge is not behind S.O.S. v2. Knowledge is FREE.
INV-05: Quarterly link verification. Dead links are worse than no links. Remove them immediately when discovered. Keep the library alive and trustworthy.
