Repo migration: GitHub → Gitea (commit `b17148b`) + +The repo moved off GitHub to a self-hosted **Gitea** at +`git.lazyeval.net` (`oli/rdbms-playground`). `tea` auto-detects this +repo correctly off the remote **even though the machine's default +`tea` login is a different host** (`git.oliversturm.com`) — verified. + +- **Durable GitHub-specifics scrubbed:** `Cargo.toml` `repository` + URL; `requirements.md` backlog note ("now tracked as Gitea + issues"); **ADR-0001 Amendment 1** reopens the prebuilt-binary + distribution channel (was "GitHub releases") as an undecided choice + for a future distribution ADR (the Decision text was *not* + rewritten, per supersede-don't-rewrite). +- **Left as historical:** all `docs/handoff/*.md` (append-only log). +- **`CLAUDE.md` gained** an *Issue tracking* working-style bullet + + an *Issue tracking — Gitea via `tea`* section (adapted from another + project; repo coordinates corrected, `tea` gotchas kept). **Working + method now: file bugs/enhancements as Gitea issues, cross-reference + in commits/handoffs; `requirements.md` + ADRs remain the source of + truth for scope/decisions; a change to a decided area still earns an + ADR.** No heavyweight planning workflow (we're near completion of + the initial requirements). +- No open Gitea issues; the 18-issue campaign backlog (#1–#18) is all + closed. V1 lives in `requirements.md`, not an issue. + +## §3. V1 — relationship visualization (the big one) + +**ADR-0044** (`docs/adr/0044-relationship-visualization.md`, Accepted +2026-06-09, **implemented 2026-06-10**). Resolves **ADR-0016 OOS-1** +and closes `requirements.md` **V1** (`[x]`). The +relationship-as-line-art half that had been "repeatedly pushed away" +now renders as **Style-A two-table connector diagrams**. + +**Design forks (all user-chosen):** +- **Style A** (two structure boxes + connector) over a compact key + card or crow's-foot ER. +- **Reach = "relationship-relevant"** (over global / show-only): + diagrams where the relationship is the *subject* — + `show relationship `, `show table `, and + `add`/`drop relationship` echoes; incidental DDL echoes (add column, + drop index, change column, plain create table) keep the prose + `References:` / `Referenced by:` form. +- **`show table` layout:** focal structure box, then a + **Relationships** section of **stacked compact** per-relationship + diagrams (over a focal-centred subgraph — no crossing lines, scales + via scroll, two-boxes-wide fits any terminal). + +**Visual conventions:** child (FK holder) on the **left**, parent +(referenced) on the **right**, arrow → (child references parent), +**`n` … `1`** cardinality, referential actions beneath, and a +**bold title row + rule** on every box so a table name can't read as +a column. Compound FKs route a shared **bus** (each endpoint stub +merges into a vertical channel that splits to the paired endpoints) +plus an explicit `(a, b) ▶ P.(x, y)` **pairing line**. +Self-referential FKs draw two same-named boxes. **Width-aware**: +side-by-side when it fits, else a **vertical stack** fallback. + +**Three implementation increments:** +- `cad90ec` — `show relationship ` full diagram (both tables as + full structure boxes). +- `a0ee323` — `show table` compact stacked diagrams + the + `Diagram|Prose` render mode. +- `0a34303` — compound-FK bus routing + pairing line, self-referential + diagrams, V1 → `[x]`. + +**Two `/runda` passes.** The design pass (pre-build) **caught an +inverted-architecture assumption** carried in from a code survey +(rendering is App-side, not worker-side; width was claimed "already +tracked" but wasn't; `show relationship` built prose in the worker). +The implementation pass confirmed ADR-compliance, UTF-8/byte-range +safety, and edge-case routing, and added a compound-from-data glue +test. The §3 **last-resort helper line was considered and rejected** +(vertical fallback + ratatui truncation cover all realistic cases). + +## §4. Key implementation facts (read before touching the renderer) + +- **Rendering is App-side.** `output_render.rs` helpers + (`render_structure`, `render_data_table`, and the new diagram + functions) are called from **`app.rs`**, never `db.rs`. The worker + returns structured data (`TableDescription`); the App formats it. + *(An Explore survey got this backwards — verify architecture claims + against the code, not a summary.)* +- **The diagram renderer** lives in `output_render.rs` under the + `// ── Relationship visualization (ADR-0044)` banner: a styled `Seg` + engine (text + `OutputSpan` runs that compose by concatenation with + offset-shifting); `render_box` (full or compact box with a title + row); `gutter_seg` + `junction` (the bus connector — routes **all** + endpoint pairs, reduces exactly to the single-column jog); + `compose_side_by_side` / `compose_vertical`; + `render_relationship_layout` (width dispatch + pairing line); + `render_relationship_diagram` (the `show relationship` entry, builds + full `DiagramTable`s from `RelationshipDiagramData`); + `render_structure_with_diagrams` (the `show table` entry: focal box + + compact diagrams; `render_structure` was refactored into section + helpers — `structure_box_lines` / `relationship_prose_lines` / + `index_lines` / `constraint_lines` — with **byte-identical** prose + output so the old snapshots held). +- **`show relationship` worker path:** `db.rs` + `RelationshipDiagramData` (rel + both endpoint `TableDescription`s) + + `Database::show_relationship` + `do_show_relationship`; runtime + `CommandOutcome::ShowRelationship` (boxed — two `TableDescription`s + dwarf the other variants) reroutes a named relationship before the + prose `show_list` fallback; event `DslShowRelationshipSucceeded`; + app `handle_dsl_show_relationship_success`. +- **The Diagram/Prose split** is in `handle_dsl_success`: it renders + diagrams for `ShowTable | AddRelationship | DropRelationship`, prose + otherwise. +- **Width:** new `App::last_output_width` (default `80`), set from + `ui.rs` `render_output_panel` next to `note_output_viewport`. + Snapshot at command time — **no live reflow** (that's V4). +- **Styling:** four new `OutputStyleClass` variants + (`DiagramTableName` / `DiagramKey` / `DiagramCardinality` / + `DiagramConnector`), mapped in `ui.rs::output_span_style` to + **existing** theme colours (no new `Theme` fields). `Seg` only ever + pushes whole strings/chars, so styled-run byte ranges are always + valid UTF-8 boundaries (exercised live by the `add relationship` + `rendered_text` test through `ui.rs`'s `text[start..end]` slice). +- **`do_show_one`'s relationship prose branch is now dead-for-users** + (the reroute supersedes it) but **retained** — reachable via the + `Database::show_list` worker API, covered by a worker test, and a + candidate text fallback for a future non-visual display option (cf. + ADR-0044 **OOS-7** relationship-display setting). Documented in + `db.rs`. +- **Two bugs the tests caught** (both in compact boxes, which the + single-relationship full-box tests didn't exercise): an eager + `widths[1]` index panic (`then_some` → `then`), and body-cell + padding under title-widening (pass the widened `widths[0]`, not the + pre-widening `label_w`). + +## §5. Remaining open landscape + +**Still `[/]` partial / `[~]` / larger (unchanged from handoff-59):** +- **V2 / S3** multi-result tabs — output-model redesign. +- **V3** whole-DB ER export; **V4** scrollable journal + Markdown + (the home for diagram live-reflow, OOS-1 here). +- **A1** app-commands — blocked on `seed` (SD1) + `hint` (H2). +- **DOC1** reference docs; **X1** logging density. + +**`[ ]` not started:** H2 `hint`, SD1 `seed`, C4 m:n, B3 +query-timeout, I1 multi-line, I1b readline, I5 cancellation, **TT5 +CI** (now Gitea Actions, ties into ADR-0001's reopened distribution +question), TT4 PTY (spec-only), D1–D3 distribution, NFR-1…7. + +**ADR-0044 OOS for later:** OOS-7 user-configurable +relationship-display setting (always-prose / always-diagram / +auto-by-width); compound display polish if needed. + +## §6. Next job — candidates + +No forced next step. By readiness: +1. **X1 logging** — mechanical, no ADR; brings instrumentation to the + `CLAUDE.md` "log liberally" bar (~25 `tracing` sites today). +2. **TT5 CI** — test infra solid (2207 green); no pipeline. Now + **Gitea Actions / Woodpecker**, not GitHub Actions — a fresh + decision tied to today's migration + ADR-0001's distribution + question. +3. **T3 residuals** (ADR-0043 §4) — two messaging-only polish items + (inline-FK arity error wording; compound-FK-violation friendly + error names only the first pair). +4. **V2/S3 multi-result tabs** or **V4 journal** — larger, + design-first (own ADR). + +## §7. How to take over + +1. Read handoffs 58 → 59 → 60, then `CLAUDE.md` (now with the + *Issue tracking — Gitea via `tea`* section), `docs/requirements.md` + (V1 now `[x]`), `docs/adr/README.md`. +2. **For relationship diagrams: read ADR-0044**, then the + `// ── Relationship visualization` block in `src/output_render.rs` + (§4 above maps the functions). +3. **Gitea/`tea`:** plain `tea issues` works here (auto-detects + `git.lazyeval.net`); the gotchas section in `CLAUDE.md` matters + (stdin-hang → `< /dev/null`; multiline bodies via temp file; the + display blind-spot for milestones/comments). +4. Codebase on `main` at `0a34303`, clean, 5 commits unpushed. +5. Process pins that paid off this session: **verify architecture + claims against the code, not a survey** (the §3 inversion); + **`/runda` after design AND after implementation** (both found real + things); **tests on the *compact* path caught bugs the full-box + path missed** — exercise every variant; **escalate genuine forks** + (every V1 design choice was the user's). Commits user-confirmed, + append-only, no AI attribution.
