-# Discrete Structural & Topological Schema Extension
-### *Formal Contract for Discrete Graph-Theoretic Ground Truth in Time-Lapse Artifacts*
-
-This specification defines the formal discrete mathematical and topological extension to the canonical time-lapse repository schema. It associates physical drawing recordings (`record_id: tla-...`) and physical artworks (`work_id: tlaw-...`) with verified graph-theoretic ground truth.
-
-Per `SCHEMA.md`, all style and aesthetic classifications are excluded; these fields record only objective discrete graph topology (incidence, vertices, edges).

-## 1. Schema Fields & Types
-
-| Field Name | Type | Value Domain | Meaning |
-|:---|:---:|:---|:---|
-| `topological_family` | string / enum | `planar_network`, `chordal_ring`, `triangulated_lattice`, `bipartite_partition`, `extremal_configuration`, `hypercube_projection`, `unclassified` | The formal topological classification of the discrete network structure inscribed. |
-| `terminal_node_count` | integer (or blank) | $\mathbb{Z}_{\ge 0}$ | Exact ground-truth count of discrete vertices/intersections in the completed work. |
-| `terminal_edge_count` | integer (or blank) | $\mathbb{Z}_{\ge 0}$ | Exact ground-truth count of connecting line segments in the completed work. |
-| `graph_invariants` | semicolon list (or blank) | Key-value pairs (e.g., `is_planar=true; chromatic_number=4; is_connected=true; diameter=3`) | Formal structural invariants verified on the completed terminal graph. |
-| `recurrence_relation_id` | string (or blank) | e.g., `MANTEL-T2-FL4`, `ANDRASFAI-5T2` | Formal identifier linking the network sequence to a symbolic recurrence relation. |
-| `derivation_manifest_ref` | string (or blank) | e.g., `tlad-graph-v1-...` | Reference identifier linking the work to a verified derivation manifest in `time-lapse-artifacts-derived`. |

-## 2. Missing-Value & "Rec01" Scope Rules (Strict Integrity)
-
-To prevent models or researchers from falsely interpreting an in-progress intermediate clip as a finished drawing, the following rules are strictly enforced per `SCHEMA.md` (§ Missing-Value Rules):
-
-1. **Single-Recording Drawings (No `RecNN` Suffix):**
-   * The fields describe the completed work and are populated directly on that row.
-2. **Multi-Clip Recordings (`Rec01`, `Rec02`, ..., `RecNN`):**
-   * **Only `Rec01` (the primary reference clip)** carries the terminal ground-truth values (`topological_family`, `terminal_node_count`, `terminal_edge_count`, `graph_invariants`).
-   * **All intermediate and non-terminal clips (`Rec02` through `RecNN`) must remain BLANK.**
-   * As defined in `SCHEMA.md`: *"Blank numeric values must remain blank; they are not zero."* An intermediate clip is an incomplete drawing state, not a graph with 0 nodes.
-3. **Pre-Standard / Fragment Holdings Without Terminal Verification:**
-   * Fields remain **blank** until an explicit human-verified ground-truth audit is performed. Blank values must never be promoted to inferred zero.
-4. **Physical Work Identity (`Work_Identity/works.csv`):**
-   * These fields also attach to `works.csv` at the `work_id` (`tlaw-...`) level, ensuring that each of the 425 physical artworks retains exactly one authoritative structural ground-truth definition.

-## 4. Validation Integration
-
-During ingestion:
-1. `tools/validate_metadata.py` verifies that `terminal_node_count` and `terminal_edge_count` are valid positive integers whenever present.
-2. The validator asserts that for any multi-clip sequence, only `Rec01` has non-blank values; if `Rec02` carries values, validation emits an error to prevent duplicate counting.
-3. Automated offline validators confirm that any `derivation_manifest_ref` resolves to a valid derivation record in `time-lapse-artifacts-derived`.
