+# pid-parser showcase
+
+Precomputed results of [pid-parser](https://github.com/dzakybd/pid-parser) on three synthetic P&ID sheets: the drawing with what the model read, the graph, the tables, and the SQL, CSV, GraphML and Cypher exports. The page calls no model.
+
+Install the skill in your own agent with `npx skills add dzakybd/pid-parser`.
+
+Drawings: synthetic sheets from [PID2Graph](https://zenodo.org/records/14803338) ([paper](https://arxiv.org/abs/2411.13929)), CC BY-SA 4.0. The drawings and the outputs derived from them are shared under CC BY-SA 4.0. The pid-parser code is MIT licensed.

+# Connection pass and review
+
+All 12 marked tiles reviewed by row (0_0–0_3, 1_0–1_3, 2_0–2_3), with overlap continuations checked. Tile 2_3 blank.
+
+## Traces
+Row 0: s21–s4–s16–s1; s18–s19–s10–s5. Split s1 oversized detection into lower control valve s1 and upper equipment s22, joined by dashed signal. Upper symbol type uncertain; no readable tag.
+Row 1: s5–s7–s13–j2; s2–j2–s14–s11–s12. j2 at (3183,2363) is a three-way process tee. Removed s3, a false detection around the upper leg of the pipe loop feeding s14. s15–j1–s17–s8; j1 at (2548,1965) is a takeoff with dashed signal to s2.
+Row 2: s8–s6 dashed signal. s21–s9 solid process continuation. s20–s6 route changes from dashed to solid at approximately (1914,3730); retained as signal with explicit mixed-style note. That four-way crossing has neither a dot nor a tee; not connected to the vertical s21–s9 route. At (1914,2705), the vertical has a clear gap; also not connected. Unmarked upper crossings are not tees.
+
+## Limitations
+Printed annotations are unusual and their exact role/readings are uncertain; no guessed line identifiers added. s12 and s15 each have only one connected pipe as drawn; no fabricated second ports. s22 specific symbol identification unresolved. Mixed style on s20–s6 is documented in graph edge notes; binary kind is signal based on dashed origin, not a claim that all its segments are dashed. Edge orientation is tracing order, not verified flow direction.
