Completes requirement V1. A compound (multi-column) FK now routes a
bus connector — each paired endpoint's stub merges into a shared
vertical channel that splits to the other side — plus an explicit
"(a, b) ▶ P.(x, y)" pairing line; the bus generalises the single-column
jog (reproducing it exactly, so prior snapshots are unchanged).
Self-referential FKs render as two same-named boxes.
- output_render.rs: gutter_seg routes all endpoint pairs via a
junction() bus; pairing line for compound FKs; compound, self-ref,
and compound-from-data (build_diagram_table glue) tests + snapshots
- compound_fk.rs: worker test that show_relationship carries both
paired column lists into the diagram payload
- db.rs: document do_show_one's now-app-superseded relationship prose
branch (retained as a worker-API/text fallback; could back a future
non-visual display option, cf. ADR-0044 OOS-7)
Second /runda pass over the implementation: confirmed ADR-compliance,
UTF-8/byte-range safety, and edge-case routing. The ADR §3 last-resort
helper line was considered and rejected (vertical fallback + ratatui
truncation cover all realistic cases). ADR-0044 marked implemented;
requirements.md V1 -> [x].
Full suite 2207 pass / 0 fail / 1 ignored; clippy nursery clean.
Two-table connector diagrams (Style A) for relationships, resolving
ADR-0016 OOS-1 and the open half of requirements.md V1. Reach is
'relationship-relevant' (show relationship / show table / relationship
DDL echoes; incidental echoes keep prose). App-side rendering, width-
adaptive side-by-side vs vertical, compound-FK pair routing, bold box
title rows. Revised after a /runda DA pass corrected three inverted-
architecture claims (App-side rendering, untracked output width,
prose-in-worker show-relationship).
Index updated per ADR-0000.
