# Open SEO Foundation

> Use when porting a pay-as-you-go SEO platform's reusable machinery: Cloudflare Workflows run orchestration (per-step Postgres scoping, partial-index single-flight guards, stale-run reconciliation), SERP rank-check adapters over a metered third-party API (live vs task-queue vs live-fallback ladders), credit estimation that matches per-call rounding, drift-free schedule anchoring for cron admission control, R2 cache keys that survive schema evolution, URL/domain research-scope grammar, AI-search (LLM mentions) fan-out with cache-only-on-complete, Durable-Object crawl scratchpads, and agent-facing MCP tool registration or in-app agent turn hooks. Source code and direct tests are ground truth; references carry decisive excerpts and graph retrieval.

# OpenSEO: metered SEO platform foundation

## Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is
historical, revision-pinned evidence rather than timeless guidance. Current
project source, tests, requirements, and runtime behavior outrank this
projection and decide what ships.

## Provenance and revision

- Source record: `open-seo`; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
- Recorded revision: `main@cd6a782092556d6f7a0e3ab1cdb66a4dada30e28`.
- Full provenance, coverage caveats, boundaries, and preserved evidence:
  `references/index.md`.

## Topic map

- Representative topics: Workflow kernel; Rank tracking; DataForSEO adapter;
  Shared infra; AI measurement; Site audit; Agent surfaces.
- Scope and retrieval questions: `references/index.md#use-this-for`.
- Complete capsule chooser: `references/index.md#load-the-matching-source-dump`.
- Detailed grouped map: `references/index.md#capsule-map`.
- Source limitations and portability boundaries: `references/index.md#boundaries`.

## Retrieval

Open the index, choose one capsule matching the active question, and load only
that capsule. Revalidate its cited source and revision before relying on it. Do
not bulk-load the inventory, treat historical claims as current truth, or apply
this foundation as a procedure.
