+
+# What This Is
+
+`ideas-to-alphas` is the **incubator** of the hyperpolymath type theory
+pipeline: the theory→practice stage where a finding from the **lab**
+(`kategoria`) is matured from **idea to alpha** before it earns its own
+production (typed) repo.
+
+> [!NOTE]
+> This repo is mid-rename. The GitHub repo and local directory are still
+> named `kategoria-pipeline` until the owner runs `gh` `repo` `rename`
+> `ideas-to-alphas` (+ local `mv`). The role split — **lab** =
+> `kategoria` (research/discovery), **incubator** = this repo
+> (idea→alpha), **portal** = `nextgen-typing` (front-page on-ramp for
+> people) — is captured in
+> `dev-notes/2026-06-16-typing-sub-estate-roles-and-lifecycle.adoc`.
+> Also update `project` `=` `"katagoria"` → `"ideas-to-alphas"` in
+> `.machine_readable/6a2/STATE.a2ml` at rename time.
+
+# Pipeline Position
+
+    katagoria  →  typell  →  typed-wasm  →  PanLL
+    (this repo)   (kernel)   (target)    (eNSAID env)
+
+`katagoria` is upstream of everything. Ideas here are **speculative**:
+proofs-of-concept, reading notes, prototype Idris2/Lean formalizations.
+They graduate to `typell` when they are ready to be integrated into the
+production verification kernel.
+
+Coordination monorepo:
+[nextgen-typing](https://github.com/hyperpolymath/nextgen-typing)
+
+# What Lives Here
+
+- Type theory prototypes — Idris2, Lean 4, Agda proofs-of-concept
+
+- Research notes on papers being read and formalized
+
+- Experimental level definitions for the TypeLL open-ended progression
+
+- Speculative session type extensions (multi-party, probabilistic,
+  temporal)
+
+- Tropical type theory experiments (connections to protocol-squisher)
+
+# What Does NOT Live Here
+
+- Production Rust code — goes in `typell`
+
+- WasmGC type safety proofs — goes in `typed-wasm`
+
+- Anything with stability guarantees — this repo is deliberately
+  unstable
+
+# Relationship to TypeLL
+
+TypeLL is an **open-ended progressive** type safety framework. The
+current L1-L10 implementation in typell was designed here first, then
+graduated. Future levels (L11, L12, …) will originate here before
+promotion.
+
+There is no fixed ceiling. katagoria is where the ceiling gets pushed.
+
+# Status
+
+Pre-alpha. Newly created (2026-04-11). Research artefacts will
+accumulate over time.
