1+# Lofi-owned schema facade over the Jazz 2 DSL2+3+Date: 2026-07-18\4+Reviewed dependency: `jazz-tools@2.0.0-alpha.53`\5+Decision: adopt a curated one-to-one re-export; reject a translating facade6+7+## Question8+9+The developer-experience contract deferred whether a lofi-owned schema facade is "honest and10+affordable" (previously gated on #7). Until now `src/schema.ts` and `src/permissions.ts` were the11+two deliberate raw-Jazz surfaces in author source, importing `schema as s` from `jazz-tools`12+directly.13+14+## Context and control15+16+The baseline (control) is the M1 arrangement: direct pinned `jazz-tools` imports in author schema17+and permission files, with the author-boundary test exempting those two files from its raw-Jazz18+rule. Two facts changed the trade-off:19+20+1. Jazz 2 replaced the publicly documented 1.x CoValue API (`co.map`, `co.list`, `co.feed`, CoText,21+ FileStream) with a relational table DSL. Public Jazz documentation describes 1.x, so a22+ transparent surface delegates authors to documentation that is wrong for the pinned version.23+2. Alpha releases change behavior without notice (see24+ [group-creator-authority-alpha53](group-creator-authority-alpha53.md)); every schema author was25+ exposed to that churn directly.26+27+## Decision28+29+Adopt the **re-export kind** of facade and reject the **translating kind**:30+31+- `@nzip/lofi/schema` exports `s`, a curated `Pick` of the pinned Jazz 2 `schema` namespace. Every32+ exposed member is the Jazz original by object identity — verified by test — so names, semantics,33+ error messages, and tooling output cannot drift from what runs underneath. The module also34+ re-exports the DSL's schema-authoring types (`App`, `Schema`, `InsertOf`, `WhereOf`, and related).35+- Curation is by omission only: the deprecated `col.rename` and the unexercised `defineSliceableApp`36+ are left out. Nothing is renamed, wrapped, or reinterpreted; a translating facade (a lofi-invented37+ schema language) remains rejected as a non-goal.38+- Author files declare data exclusively through `@nzip/lofi/schema`. The generated author-boundary39+ test now applies the raw-Jazz rule to every author source file with no exemptions. Direct40+ `jazz-tools` imports remain possible as an explicitly unsupported escape hatch, per the existing41+ escape-hatch row of the contract.42+43+Honest: the facade translates nothing, so it cannot misrepresent the vendor surface. Affordable: it44+re-exports rather than reimplements, so its maintenance cost is the curation list and one identity45+test.46+47+## Procedure and evidence48+49+- `package/schema/mod.ts` — the facade; `package/schema/mod_test.ts` verifies member identity50+ against `jazz-tools` and round-trips `defineApp`/`definePermissions` through the facade.51+- `package/schema/merge_sync_test.ts` — concurrent-writer merge semantics (lww, counter, g-set) over52+ a real JazzServer with two synced clients and a fresh observer.53+- `package/schema/migration_test.ts` — the schema-evolution surface (`defineSchema`,54+ `defineMigration`, `renameTableFrom`, `add`/`drop`/`renameFrom`) over a real JazzServer: forward55+ and backward lens directions plus the missing-migration deploy guardrail.56+- `apps/reference/tests/author-boundary_test.ts` — rejects `jazz-tools` imports in all author57+ source, including `schema.ts` and `permissions.ts`.58+- `deno task check` and `deno task build` pass with the reference app (and therefore the starter,59+ which copies it) migrated to the facade.60+61+## Contract delta62+63+The author-boundary rows for `schema.ts` and `permissions.ts` no longer allow direct pinned Jazz64+declarations; both declare through `@nzip/lofi/schema`. The schema safe default changes from "use65+the smallest verified Jazz 2 surface" to "expose the pinned DSL through the re-export, never a66+second schema language." Version bumps of `jazz-tools` become package releases: upstream renames are67+absorbed by the facade instead of breaking application schemas.68+69+## Conformance findings (alpha.53)70+71+The column-type conformance suite (`package/schema/conformance_test.ts`, task72+`deno task test:conformance`, part of `deno task check`) exercises every facade column type through73+the official policy test harness against the real engine. Verified working end to end: string,74+boolean, int (within i32), float, timestamp storage, enum, ref, json, array, bytes (≥32-byte75+payloads observed reliable), `.optional()`, `.default()`, `.transform()` (view type on76+insert/read/update; `where` filters take the stored type), lww merge (the default; concurrent77+conflicts resolve to the last write to reach the server on every replica), counter merge78+(single-session), g-set merge (single-table apps, cross-writer union), policy conditions over typed79+columns with `anyOf` alternatives, `permissionIntrospectionColumns` (`$canRead`/`$canEdit`/80+`$canDelete` selected per row, mirroring the deployed policy), and the full migration surface81+(`defineSchema`, `defineMigration`, `renameTableFrom`, `add`/`drop`/`renameFrom`; forward and82+backward lens directions carry data correctly, and deploying a changed schema without its migration83+reports `status: "missing"` and withholds permissions). The three merge strategies (`lww`,84+`counter`, `g-set`) are the complete collaborative-value surface of the pinned alpha — Jazz 285+exports no successor to the 1.x CoValue types. Engine and type bugs found and pinned in the suite so86+an alpha bump surfaces any change:87+88+1. **`.merge()` and `.transform()` erase column typing.** The legacy untyped signatures89+ (`merge(): this`, `transform(): ColumnBuilder`) shadow the typed overloads, degrading the column90+ to `ColumnBuilder` and poisoning the whole table's row types. Runtime unaffected. Workaround91+ documented on `@nzip/lofi/schema`: cast the result back (e.g.92+ `as unknown as93+ IntColumn<false, true>`, `as unknown as StringColumn<false, false, string[]>`).94+2. **Int columns are i32 at runtime.** Values outside i32 are rejected with95+ `InvalidArg … expected96+ i32` despite the `number` static type. Pinned.97+3. **Timestamp where-equality matches every row** (verified with distinct non-epoch dates), and98+ running that query wedges the FFI driver: the next harness boot in the same process hangs on its99+ first write. Pinned; the scalar test deliberately runs last.100+4. **A g-set column destabilizes cross-table writes.** In a process that has booted harnesses101+ before, writing a sibling table before the g-set table's first write hangs indefinitely102+ (reproduced five times in bisection); a fresh process may not reproduce it. Covered by a tolerant103+ subprocess canary; g-set coverage stays isolated in a single-table app.104+5. **Short byte payloads are unreliable.** A 2-byte insert has been observed succeeding, failing105+ with `WriteError … data too short for column value`, and hanging, depending on process context.106+ Covered by a tolerant subprocess canary.107+6. **Counter merge semantics are inconsistent across replica lifetimes.** Verified with two synced108+ clients plus a fresh observer (`package/schema/merge_sync_test.ts`): the server keeps the last109+ causally ordered update value and sums only concurrent updates, while live replicas apply every110+ update — including the echo of their own reconnected write — as a delta. A replica that watched111+ the history diverges permanently from what a fresh boot reads (observed: canonical 8, first112+ writer 13 after a concurrent 5/3 conflict on 0; canonical 3, live replicas 5 after causal 2 then113+ 3). The full matrix is pinned. G-set union merge, by contrast, is verified convergent across114+ writers and fresh boots.115+116+Hangs cannot be cancelled through FFI, so the canaries run in child processes that force-exit117+(`package/testdata/gset_hang_canary.ts`, `package/testdata/bytes_short_payload_canary.ts`).
