From db3dd3c3a5f4c5cde9a736cb688f05af9f79d718 Mon Sep 17 00:00:00 2001 From: Ralph Amissah Date: Mon, 25 May 2026 10:21:59 -0400 Subject: separate abstraction lib from output processing create new directories under ./src/sisudoc ocda & outputs in order to separate the document abstraction library from downstream output processing (stuff broken till paths & modules fixed) ---

+  sisudoc.abstraction - public surface of the document-abstraction
+  library.
+
+  Pipeline position: markup -> abstraction -> output.
+  This package is the abstraction stage. The output stage lives in
+  sisudoc.io_out and consumes the values produced here.
+
+  Entry points:
+    - spineAbstraction!() (from sisudoc.meta.metadoc) - A-layer:
+        builds the in-memory document object model from a manifest
+        (pod path, .sst path). Reads the document body, parses YAML
+        headers, returns a struct with .abstraction (the object
+        model) and .matters (the conf/meta/src wrapper).
+    - docAbstraction!()   (from sisudoc.meta.metadoc_from_src) -
+        B-layer: builds the abstraction from already-loaded body
+        text plus a pre-built ConfComposite. Pure, no file I/O.
+
+  The A-layer is a thin wrapper over the B-layer; consumers that
+  want a minimal-dependency entry should use docAbstraction!()
+  directly.
+
+  Serialisation:
+    - sisudoc.abstraction.ssp - PEG-parsable text serialisation of
+        the abstraction (the .ssp format). See specs/doc-abstraction-
+        format/ for the format reference.
+
+  This file is a re-export-only surface. No logic lives here; it
+  exists so external consumers can `import sisudoc.abstraction;` and
+  reach the entry points without depending on spine's directory
+  layout.
