# FeedTheJoe Library

> A research library on how websites are discovered, understood and cited by search engines and AI systems. 143 volumes on 5 shelves by Joseph W. Anady, published by THATDEVELOPERGUY LLC.

Every volume has a reading page, which is the address to cite, and a Markdown edition at the same address ending in .md. Library release 2026.09.12-g40; site edition 2026-10-14. The whole corpus is at https://library.feedthejoe.com/llms-full.txt and the machine catalogue at https://library.feedthejoe.com/catalog.json.

## Operating model

How the disciplines work as one accountable system: routing, handoffs, acceptance, integration and decision ownership.

- [Operating model](https://library.feedthejoe.com/operating-model/00-operating-model.md): A website problem is not automatically an SEO task.
- [Master routing protocol](https://library.feedthejoe.com/operating-model/01-master-router.md): The purpose is to classify work, load appropriate instructions and enforce interfaces. Telling a model it is “the world's best” in 26 jobs does not supply tools, credentials, access, current documentation or independent verification.
- [Handoff contracts](https://library.feedthejoe.com/operating-model/02-handoff-contracts.md): A handoff carries a question to be resolved, not merely a conclusion.
- [Acceptance and independence](https://library.feedthejoe.com/operating-model/03-acceptance-and-independence.md): Acceptance tests the stated requirement on the stated build and environment. A builder cannot redefine a failed requirement after seeing the result.
- [Build public expertise from the internal discipline library](https://library.feedthejoe.com/operating-model/04-search-expertise-publishing.md): The private operating layer teaches an AI assistant how to route work, gather evidence and avoid conflicting fixes.
- [Integrate the discipline library into an actual AI coding project](https://library.feedthejoe.com/operating-model/05-integration-guide.md): The downloaded package contains role charters, standalone prompts, an advisory router and evidence record checks.
- [Decision ownership and conflicting repair matrix](https://library.feedthejoe.com/operating-model/06-conflict-resolution.md): “Exclusive” means one accountable decision owner, not an isolated silo. Implementation may be carried out by another authorized operator.
- [Full audit coverage without launching 26 uncontrolled agents](https://library.feedthejoe.com/operating-model/07-full-audit-coverage.md): A scoped task activates only the necessary specialists. A comprehensive website audit accounts for all 26 roles by marking each active, review only, not applicable with a reason, or blocked.
- [Instructions for AI assisted use of this library](https://library.feedthejoe.com/operating-model/agents.md): Use the current project facts and explicit client authorization first. For library guidance, use the new researched modules and rewritten core guides before legacy material.
- [Change log](https://library.feedthejoe.com/operating-model/changelog.md): Added all 26 user requested roles with source linked charters, standalone prompts and distinct publication briefs; a master routing/ownership model; eight cross discipline playbooks; six unapproved methodology drafts; private evidence/coverage/acceptance…
- [The 26 discipline operating library](https://library.feedthejoe.com/operating-model/library-disciplines.md): 09-d26 · 9 September 2026.
- [SEO / AIO Library](https://library.feedthejoe.com/operating-model/library-readme.md): html for the integrated offline browser. It now includes all 26 professional role charters, their operating model, cross discipline playbooks, public content workbench and the prior current/legacy library.
- [26 discipline validation](https://library.feedthejoe.com/operating-model/discipline-validation.md): 09-d26. These are artifact/tool validation results, not production site acceptance or an independent external audit.
- [26-Discipline Expansion](https://library.feedthejoe.com/operating-model/discipline-expansion-report.md): The updated SEO library now contains all 26 user requested professional responsibilities, with the original numbering preserved.
- [Discipline gap map](https://library.feedthejoe.com/operating-model/discipline-gap-map.md): This maps the operational coverage added in this edition. It does not claim that every related concept was absent from the million word baseline or that every inherited assertion has been verified.
- [Discipline expansion](https://library.feedthejoe.com/operating-model/discipline-source-register.md): Reviewed 9 September 2026. These 49 source records supplement, not replace, the baseline S01 to S52 register. Some sources overlap intentionally so each expansion role has a self contained authority trail.
- [Discipline library integration snippet](https://library.feedthejoe.com/operating-model/agents-snippet.md): md only with authorization. Replace LIBRARY_ROOT with the verified project relative library path; do not delete existing instructions.
- [Discipline templates](https://library.feedthejoe.com/operating-model/templates-disciplines.md): All templates start unverified, unassessed or BLOCKED. Null means unknown, not zero. Replace planning placeholders only with verified project facts and actual authorization; never fill them with plausible inventions.
- [Discipline utilities](https://library.feedthejoe.com/operating-model/disciplines-readme.md): 10+; standard library only. The existing four baseline utilities remain in place. The two additions are local decision support tools, not an agent runtime, credential system or deployment service.

## Playbooks

End to end procedures that cross several charters, with the evidence each step must leave behind.

- [Cross discipline playbooks](https://library.feedthejoe.com/playbooks/library-playbooks.md): Use these dependency oriented workflows with the routing protocol. They coordinate specialist work without merging distinct evidence states or granting production permissions.
- [Bubbles: outside in availability and public reachability](https://library.feedthejoe.com/playbooks/01-bubbles-public-reachability.md): An intended public customer journey fails, or works only on a private/Tailscale connection. Bubbles is a host label, not evidence of its OS, addresses or service names.
- [Contact form to actual mailbox: an end to end evidence chain](https://library.feedthejoe.com/playbooks/02-contact-to-mailbox.md): A user sees form success but there is no confirmed inquiry. Use synthetic data and an authorized controlled recipient; this playbook grants no permission to email real customers.
- [From public delivery to useful answers and observed AI citations](https://library.feedthejoe.com/playbooks/03-discovery-to-ai-citations.md): The business wants relevant search/AI visibility, or a particular named surface does not show its content. No position or citation can be guaranteed by completing the checklist.
- [Browser and accessibility regressions across a complete task](https://library.feedthejoe.com/playbooks/04-browser-accessibility.md): A critical task fails in a browser/device or cannot be completed with keyboard/screen reader operation. The acceptance matrix must identify actual versus emulated environments.
- [Improve measured performance without damaging the website](https://library.feedthejoe.com/playbooks/05-performance-without-regressions.md): A measured field or lab bottleneck affects representative customer journeys. The goal is not an isolated score improvement at any cost.
- [Turn verified work into a public expertise asset](https://library.feedthejoe.com/playbooks/06-evidence-to-public-expertise.md): A documented method or actual authorized engagement can answer a distinct buyer question. This is a publication workflow, not an instruction to declare expertise without proof.
- [Coordinate hostname, URL and content migrations](https://library.feedthejoe.com/playbooks/07-migration-and-url-changes.md): An approved migration changes hosting, hostname, routes, content relationships or identity references. Do not initiate a domain consolidation merely because two brands exist.
- [Preflight, controlled release and fresh acceptance](https://library.feedthejoe.com/playbooks/08-release-and-independent-acceptance.md): An actual owner authorized change has a defined build/environment and predeclared acceptance contract. The library itself performs no deployment.

## Reference modules

Researched guidance on search engines, AI surfaces, crawling, structured data and measurement, plus the records of how the library was audited.

- [Agent access, MCP and security boundaries](https://library.feedthejoe.com/reference/framework-agent-access-security.md): A readable website and an authenticated tool interface solve different problems. Do not install an MCP server, expose a database or publish privileged actions merely to satisfy an SEO checklist.
- [AI answer observation and controlled evaluation](https://library.feedthejoe.com/reference/framework-ai-observation-protocol.md): An observation panel is a controlled sample, not a census of every answer an engine gives. Begin with a business question such as whether a factual service page is cited for a defined set of customer needs.

- [Regional Search eligibility and policy differences](https://library.feedthejoe.com/reference/framework-regional-search-eligibility.md): Record the business's operating jurisdiction, the content's intended market and the searcher's location. They are not interchangeable.
- [Research maintenance and documentation drift control](https://library.feedthejoe.com/reference/framework-research-maintenance.md): Each maintained rule needs an owner, current source, observed date, affected modules and a next review condition.
- [Structured data lifecycle and feature eligibility](https://library.feedthejoe.com/reference/framework-schema-lifecycle.md): Ask whether the JSON is syntactically valid, whether the vocabulary describes the page truthfully, and whether a named consumer currently supports a related feature.
- [Schema types in 2026](https://library.feedthejoe.com/reference/framework-schema-types-2026.md): org vocabulary and search engine feature support are separate layers. A valid type can describe content even when Google does not offer a corresponding rich result.
- [ChatGPT Search](https://library.feedthejoe.com/reference/framework-searchgpt.md): This filename is retained for compatibility with the earlier library, but the subject is ChatGPT Search and the currently documented publisher controls.
- [SEO release contracts and reproducible acceptance tests](https://library.feedthejoe.com/reference/framework-seo-release-contracts.md): “SEO installed” is not a release criterion.

This edition creates a real decision framework while rejecting the implication that a universal ranking algorithm is available.
- [Executed validation](https://library.feedthejoe.com/reference/validation.md): All 24 unit tests passed locally. txt. Tests exercise the four new utilities, including deliberately invalid inputs; they do not execute the preserved original script or legacy code examples.
- [SEO library audit and research update](https://library.feedthejoe.com/reference/audit-report.md): 09
- [Coverage matrix](https://library.feedthejoe.com/reference/coverage-matrix.md): This is a coverage disclosure, not a pass/fail score. Complete structural inventory and hash preservation apply to all 146 unique originals.
