Continues from handoff-58 (H1a done). This +session did **three** distinct things, in order: (1) a +**tracking-integrity audit + reconciliation** of `requirements.md` +against the actual code; (2) a **partials sweep** closing V5, H3, +and a new V5a; (3) the big one — **T3 compound-PK foreign-key +references**, designed in **ADR-0043**, `/runda`-verified twice, +and implemented end-to-end across both surfaces. + +## §1.

The tracking reconciliation (read this — it changes how you plan) + +Planning off handoffs/`requirements.md` was **unreliable**: an +audit of all 35 `[ ]` items against the source found **~46 % +mis-marked**, overwhelmingly *under*-claimed (tab completion `I3` +and syntax highlighting `I4` were shipped but marked "not yet +implemented"). Root cause: the **binary legend** — a shipped +feature, a half-built one, and an untouched one all wore the same +`[ ]`. + +Fix (commit `28e7596`): added a **`[/]` "partial / in progress"** +marker to the legend, with a dated reconciliation note. Re-marked: +- **7 shipped-but-`[ ]` → `[x]`:** S1, S4, S5, I1a, I3, I4, C1. +- **9 substantially-built → `[/]`** with explicit gap notes: S3, + A1, V1, V2, V5, T3, H3, DOC1, X1. +- Fixed a **false `CLAUDE.md` claim** ("Tier 4 is wired") — no PTY + tests exist; TT4 is spec-only. + +**Discipline going forward:** move items `[ ]` → `[/]` → `[x]`; +keep the gap note current. Don't trust a marker without checking +the code — verify empirically. + +## §3. The partials sweep (V5, H3, V5a) + +Three small/medium, no-ADR partials closed (the others — V1, S3/V2, +A1, DOC1, X1 — need an ADR / output-model redesign / new features, +so were left `[/]`, see §5): + +- **V5 `[x]`** (`8dec784`): `show tables` / `show relationships` / + `show indexes` as one `Command::ShowList { kind }`; read-only + worker `show_list`. 10 tests. +- **H3 `[x]`** (`757711f`): `help ` per-command detail + (HELP node takes an optional `BarePath` topic; `note_help_topic` + renders every command sharing the entry word) + `help types` + + friendly unknown-topic pointer. 9 tests. +- **V5a `[x]`** (`1d898ad`): singular `show relationship ` / + `show index ` detail — folded into `ShowList { kind, name: + Option }`. Raised + closed this session (it was the + honest tracked home for V5's `[]` clause). + +## §4. T3 — compound-PK foreign-key references (the big one) + +**ADR-0043** (`docs/adr/0043-compound-pk-foreign-key-references.md`, +Accepted + implemented). The open leg of T3: a FK that *references* +a parent's compound PK. The audit found single-column FK woven +through ~15–20 sites; it earned an ADR, not an inline build. + +**Four forks, all user-confirmed at the recommended option:** +- **F-A** reference the parent's **full** PK (subset/UNIQUE-target + OOS), matched **positionally** to an equal-length child list. +- **F-B** **house-style uniform lists, no migration** — the + decisive simplifier: the user confirmed **back-compat is not + required** (pre-release, no installed base), so `project.yaml` + endpoints became `columns: [a, b]` (like `primary_key: [id]`), + metadata `TEXT` cells store the list **comma-joined** (bare for + single), and **no F3 migrator / version bump** was needed. +- **F-C** parenthesized DSL `from P.(a, b) to C.(x, y)` (single + bare form unchanged). +- **F-D** bare table-level SQL `FOREIGN KEY (x,y) REFERENCES P` + auto-expands to the parent's full PK when arities match. + +**Implementation (two commits):** +- `b14f019` — **the refactor**: relationship model `String → + Vec` through all six layers (`AddRelationship` / + `SqlForeignKey` AST, `RelationshipSchema`, metadata, + `project.yaml`, `ReadForeignKey`, `RelationshipEnd`). **Single- + column behaviour preserved** (one-element vecs); the existing + single-column relationship suite was the regression net. This is + the safe green checkpoint. +- `4752ba2` — **the grammar + tests**: multi-column parsing on both + surfaces (`AR_PARENT_COLS`/`AR_CHILD_COLS` Choice in `ddl.rs`; + `FK_*_COL_LIST` Repeated in `sql_create_table.rs`; + `consume_fk_reference` + the table-level/ALTER parsers collect + lists). Executor: `resolve_fk_parent_columns` (F-A validation + + F-D auto-expand + arity), per-pair `check_fk_type_compat`, + `schema_to_ddl` multi-column emission, `pragma_foreign_key_list` + read **grouped by `id`, ordered by `seq`** (positional pairing), + auto-name joins lists, `--create-fk` per-column, multi-column + teaching echo. 12 tests in `tests/it/compound_fk.rs`. + +**`/runda` ran twice** (once on the ADR pre-build, once on the +finished code). The post-build pass **found 3 coverage gaps and +they were closed**: save→rebuild round-trip (the riskiest — proves +comma-encode/decode + yaml + FK reconstruction survive a text→db +rebuild), undo (one step), per-pair type-mismatch. + +**Two residuals, confirmed non-blocking (noted in code):** +1. inline `col REFERENCES P(a,b)` gives a *generic* arity error, + not the ADR's tailored "use the table-level form" pointer. +2. a compound-FK *violation*'s friendly error names only the first + column pair (the ADR-0019 facts model is single-column). +Both are messaging-only; FK correctness/enforcement is unaffected. + +**Process note (a real scare):** a broad regex script over test +files (to wrap `add_relationship` call args + struct fields in +`vec![]`) **over-reached into lib structs** it shouldn't have +(`RelationshipSelector::Endpoints`, `FailureContext`/ +`TranslateContext` — all deliberately single-column), briefly +breaking the lib build. Recovered by reverting those specific +sites. Lesson: scripted edits across `src/` are dangerous when a +field name (`parent_column`) is shared between the struct you're +migrating and ones you're not — prefer compiler-guided manual fixes +or scope the script tightly. + +## §5. Remaining open landscape (now trustworthy) + +**Still `[/]` partial (need design/ADR or are larger):** +- **V1** relationship line-art visualization — **needs a + visualization ADR** (the most-requested deferred item). +- **S3 / V2** multi-result tabs — output-model redesign (single + buffer → tab abstraction). +- **A1** app-commands — blocked on `seed` (SD1) + `hint` (H2), + both unbuilt features. +- **DOC1** reference docs — writing effort. +- **X1** logging density — broad/mechanical (~25 `tracing` sites + today; `CLAUDE.md` wants "log liberally"). + +**`[ ]` not started:** H2 `hint`, SD1 `seed`, C4 m:n, B3 +query-timeout, I1 multi-line, I1b readline, I5 cancellation, TT5 +CI, TT4 PTY (spec-only), D1–D3 distribution, NFR-1…7. + +## §6. Next job — candidates + +No forced next step. By readiness: +1. **V1 relationship visualization** — design-first (its own ADR). + The user has flagged it repeatedly; it's the prominent open + design item. +2. **X1 logging** — mechanical, no ADR; brings the codebase to the + `CLAUDE.md` "log liberally" bar. +3. **TT5 CI** — test infra is solid (2193 green); no workflow yet. +4. The two T3 residuals (§4) — small messaging polish if they bug + you. + +## §7. How to take over + +1. Read handoffs 57 → 58 → 59, then `CLAUDE.md`, + `docs/requirements.md` (now with the `[/]` marker + the §2 + reconciliation note), `docs/adr/README.md`. +2. **For relationships/FK: read ADR-0043.** The model is list-based + (`Vec`); single-column is the one-element case. +3. Codebase on `main` at `4752ba2`, clean, 8 commits unpushed. +4. Process pins that paid off: **verify the tracker against code, + don't trust the marker**; **escalate genuine forks** (the four + ADR-0043 forks were the user's); **`/runda` after planning AND + after implementation** (the post-build pass found 3 real gaps); + **scope scripted edits tightly** (§4 scare). Commits + user-confirmed, append-only, no AI attribution.
