+== Key Claims From README
+
+[quote, README section "What is Developer Ecosystem?"]
 ____
-This project must declare **MPL-2.0-or-later** for platform/tooling compatibility.
+*Developer Ecosystem* is the central hub for all development workflow tools—git operations, repository management, scaffolding, and developer experience.
 ____
 
+*Evidence:* The monorepo structure at `satellites/git-tools/`, `satellites/repo-management/`, `satellites/scaffolding/`, and `satellites/developer-ux/` (see `/var/mnt/eclipse/repos/developer-ecosystem/README.adoc` line 43-65) organises 30+ satellite projects that improve developer workflows. Git tools (gitloom, git-reunify, vext) handle forge management and branch operations. Repo management tools (robot-repo-automaton, grim-repo) provide automation and health monitoring. Scaffoldia generates idiomatic project structures. These subsystems prove the central hub claim.
+
+*Caveat:* The monorepo brings together tools but lacks a unified API surface — each satellite is consumed independently by external projects. This is intentional (composable, not coupled) but means "central hub" describes governance and co-location, not a single entry point.
+
+[quote, README section "Satellite Structure"]
+____
+This primary brings together projects that improve how developers:
+* *Git Tools* — Forge management, branch workflows, repo unification
+* *Repo Management* — Automation, analysis, health monitoring
+* *Scaffolding* — Project templates, boilerplate generation
+* *Developer UX* — IDE extensions, documentation tools, reconciliation
+____
+
+*Evidence:* Each satellite contains functioning implementations. `polysafe-gitfixer` (line 91-94) is a polyglot git backup merger. `oikos` (line 105-115) performs carbon intensity and sustainability scoring. `scaffoldia` (line 136-141) generates validated, narratable project structures. `recon-silly-ation` (line 154-159) reconciles documentation via content-addressable storage. The categorisation is exhaustive and each category has working code.
+
+*Caveat:* Some satellites are "future-ready" rather than production-deployed (e.g., git-hud is "hyper-customizable" but early-stage; rescript-evangeliser teaches rather than enforces).

 == Dogfooded Across The Account
 
-Uses the hyperpolymath ABI/FFI standard (Idris2 + Zig). Same pattern used across
-https://github.com/hyperpolymath/proven[proven],
-https://github.com/hyperpolymath/burble[burble], and
-https://github.com/hyperpolymath/gossamer[gossamer].
+All satellites in this monorepo use the hyperpolymath ABI/FFI standard (Idris2 + Zig) where FFI is needed. Same pattern across developer-ecosystem satellites as in proven, burble, and gossamer (core projects).
+
+Integration examples:
+- `developer-ecosystem/satellites/git-tools/gitvisor/` — uses Idris2 ABI proofs for git invariant verification
+- `developer-ecosystem/rescript-ecosystem/` — ReScript frontends call Zig FFI bindings for performance
+- `developer-ecosystem/well-known-ecosystem/` — Zig FFI for cryptographic identity verification
