+# DEPRECATED — the canonical inventory moved.
+#
+# This file is no longer the source of truth. As of 2026-10-02 the canonical
+# inventory is:
+#
+#     GrayCodeAI/graycode-eco  ->  ecosystem.yaml
+#
+# Why it moved: a product cannot own the registry of its siblings. This file
+# lived inside `rho` and described itself as canonical, which meant `rho` could
+# rename itself without signalling the other nine repositories. It did exactly
+# that — the organization holds `hawk` and `eyrie` as redirects from the prior
+# names of `rho` and `flux`. The list also omitted `beam` entirely.
+#
+# What is still true below, and what is not:
+#
+#   - The `contracts` block is accurate and is now maintained in the roof.
+#   - The repository list is INCOMPLETE: `beam` is missing, and `lean-prover`
+#     and `graycode-logo` are unaccounted for.
+#   - `tracks_eagle` and other historical fields describe a removed ecosystem.
+#
+# Consumers should migrate:
+#
+#   scripts/ecosystem-manifest.sh          reads this file
