+## 📚 How the pipeline works
+
+The full mechanism behind these outputs is documented in the GitGalaxy docs site's **Legacy
+Bridge** chapter: the [refraction controller](https://squid-protocol.github.io/gitgalaxy/05-01-legacy-refraction-controller)
+(the deterministic COBOL→architecture mapping), [Spring Boot scaffolding](https://squid-protocol.github.io/gitgalaxy/05-02-spring-boot-scaffolding),
+[entity & memory mapping](https://squid-protocol.github.io/gitgalaxy/05-03-entity-and-memory-mapping)
+(`PIC`/`OCCURS`/`REDEFINES` → JPA), [API & service contracts](https://squid-protocol.github.io/gitgalaxy/05-04-api-and-service-contracts),
+the [autonomous agent tickets](https://squid-protocol.github.io/gitgalaxy/05-05-autonomous-agent-tickets)
+that populate `ai_agent_jobs/`, and the [batch test harness](https://squid-protocol.github.io/gitgalaxy/05-06-batch-test-harness)
+that generated this whole repo. The source lives in the engine's
+[`gitgalaxy/tools/cobol_to_java`](https://github.com/squid-protocol/gitgalaxy/tree/main/gitgalaxy/tools/cobol_to_java).
+
+Several of the source repos here (cics-genapp, cics-java-jcics-samples, gnucobol) also appear in
+[gitgalaxy-raw-output](https://github.com/squid-protocol/gitgalaxy-raw-output) as unedited
+analysis scans, and in the [language-crucible](https://github.com/squid-protocol/language-crucible)
+COBOL/JCL benchmark corpus — the same codebases, seen by the analysis, benchmark, and
+translation legs of the system.
+
+## The GitGalaxy constellation
+
+This repo is one strand of the web of repos that build, prove, and showcase
+[GitGalaxy](https://github.com/squid-protocol/gitgalaxy):
+
+- [gitgalaxy](https://github.com/squid-protocol/gitgalaxy) — the engine (this repo showcases its `cobol_to_java` pipeline)
+- **cobol_to_java_examples** — *you are here*: 10 auto-generated, compiling Spring Boot translations
+- [gitgalaxy-raw-output](https://github.com/squid-protocol/gitgalaxy-raw-output) — unedited analysis scans of real repos, including several of this repo's sources
+- [language-crucible](https://github.com/squid-protocol/language-crucible) — the pinned adversarial corpus (COBOL/JCL heavy) behind the engine's regression gate
+- [keyword-rosetta](https://github.com/squid-protocol/keyword-rosetta) — one planted program in 46 languages, measuring cross-language measurement consistency
+- [gitgalaxy-population-analyses](https://github.com/squid-protocol/gitgalaxy-population-analyses) — statistical analyses over the scan population
+- [squid-telemetry](https://github.com/squid-protocol/squid-telemetry) — public distribution/adoption metrics
+- Docs: [architecture & methodology site](https://squid-protocol.github.io/gitgalaxy/) · [Legacy Bridge chapter](https://squid-protocol.github.io/gitgalaxy/05-01-legacy-refraction-controller) · [Museum of Code](https://squid-protocol.github.io/gitgalaxy/museum-of-code/) · [gitgalaxy.io](https://gitgalaxy.io/)
