Summary

First of several phased slices toward #113 (see plan discussion on the issue) — introduces the durable SQLite catalog from the approved workspace-sharding.md design as the source of truth for Document/Collection titles and hierarchy, kept in sync by dual-writing from the service layer alongside each Y.Doc mutation. The existing single global Y.Doc stays the one real content shard for now — this does not attempt the full per-Document/per-Collection shard split, shard-aware WS/MCP routing, SSE feed, or shard-scoped holds/Awareness, which are large enough to warrant their own follow-up issues (to be filed after this lands).

  • New tables (spaces, catalog_documents, catalog_collections, record_locator, catalog_revisions, catalog_outbox) per §3.1/§4, with a simplified single-transaction committed-write path (no cross-shard pending_content staging yet, since nothing spans shards until a real shard split exists).
  • documents.ts/collections.ts dual-write to the catalog on create/rename/move/delete. Create now reserves the id in the workspace-wide record locator before touching the Y.Doc, replacing the prior silent-overwrite-on-duplicate-id behavior with RecordIdConflictError (§3.1).
  • +page.server.ts/+layout.server.ts (home page + sidebar) now read the catalog instead of the Y.Doc directly.
  • ensureCatalogBootstrapped() backfills the catalog from existing Y.Doc content the first time a workspace/shard resolves — an explicit dev/test convenience, not §7's versioned/checksum-verified production migration (that's a separate future issue).
  • parentDocumentId is deliberately not a hard foreign key: a Document can be created by a client writing directly to the Y.Doc over Yjs sync, bypassing the service layer entirely (a supported pattern — see audit-coverage.md and tests/e2e/tier-a.test.ts's direct-Yjs-client cases). A strict FK there would throw on an otherwise-valid nested create_document call; caught by a failing tests/e2e/tier-a.test.ts/src/lib/mcp/server.test.ts case during implementation and fixed before this PR.

Test plan

  • npm run test — 644/644 passing
  • npm run lint — clean
  • npm run check — clean
  • Manual verification: fresh npm run dev against an empty DB boots and bootstraps the catalog; created a document via the real createDocument form action (curl against the running dev server) and confirmed catalog_documents/catalog_revisions/catalog_outbox all updated correctly, with both the home page and sidebar consistently reflecting the new document

    • Imports existing documents and collections during workspace setup.
    • Supports catalog-aware searches and operations across document shards.
  • Bug Fixes
    • Prevents duplicate IDs across documents, collections, and records.
    • Improves workspace isolation and cross-workspace data consistency.
    • Enforces database relationships for more reliable catalog data.

…se A)

Introduces the durable SQLite catalog from docs/specifications/workspace-sharding.md
(spaces, catalog_documents, catalog_collections, record_locator, catalog_revisions,
catalog_outbox) as the source of truth for Document/Collection titles and hierarchy,
kept in sync by dual-writing from the service layer alongside each Y.Doc mutation.
The existing single global Y.Doc stays the one real content shard for now — this is
the first of several phased slices toward #113's full shard-aware architecture, not
the full cutover (see docs/specifications/workspace-sharding.md's approved design).

- New tables + ensureCatalogBootstrapped() dev/test backfill (src/lib/server/catalog.ts)
- documents.ts/collections.ts dual-write on create/rename/move/delete, replacing
  silent id-collision overwrite with RecordIdConflictError (§3.1's locator reservation)
- +page.server.ts/+layout.server.ts now read the catalog instead of the Y.Doc directly
- parentDocumentId is deliberately not a hard FK: a Document can be created by a
  client writing directly to the Y.Doc over Yjs sync, bypassing the service layer
  entirely (a supported pattern per audit-coverage.md) — verified via tier-a.test.ts

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds a workspace-scoped SQLite and Y.Doc catalog. It adds default-space bootstrapping, lifecycle tracking, record-ID conflict checks, composite foreign keys, shard-aware service operations, and catalog-based route loading.

Changes

Workspace Catalog Synchronization

Layer / File(s) Summary
Catalog storage and migration
src/lib/server/db/*, drizzle/0002_lovely_stranger.sql, drizzle/meta/*
Adds spaces, catalog tables, record locators, revisions, outbox events, composite foreign keys, unique space keys, and SQLite foreign-key enforcement.
Catalog operations and lifecycle
src/lib/server/catalog.ts, src/lib/server/catalog.test.ts
Adds transactional document and collection mutations, workspace filtering, revision and outbox updates, recursive deletion, locator management, and lifecycle tests.
Workspace catalog bootstrap
src/lib/server/workspace-store.ts, src/lib/server/workspace-store.test.ts, src/lib/server/catalog.ts, src/lib/server/catalog.test.ts
Bootstraps stable default spaces, backfills existing Y.Doc records, and exposes defaultSpaceId through workspace context.
Document and collection synchronization
src/lib/services/documents.ts, src/lib/services/collections.ts, src/lib/services/services.test.ts, src/routes/+layout.server.ts, src/routes/+page.server.ts
Synchronizes document and collection mutations with the catalog, rejects cross-type ID collisions, and loads workspace-scoped catalog data in routes.
Shard-aware records, permissions, holds, and search
src/lib/services/records.ts, src/lib/services/permissions.ts, src/lib/services/holds.ts, src/lib/services/search.ts, src/lib/services/services.test.ts
Resolves catalog-selected shards for records, permissions, holds, releases, and search operations.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to 783fd

Record creation and deletion can leave the durable record locator inconsistent with stored content when one write fails, causing records to become inaccessible or routed to the wrong shard. This merge-blocking correctness risk should be addressed before merging.

…isions, and cross-workspace scoping

- Thread one shared transaction through each catalog lifecycle mutation,
  its revision bump, and its outbox insert (previously separate calls,
  some not transacted at all) — a crash could leave a committed catalog
  change with no matching revision/outbox event.
- createDocument/createCollection now also check the live Y.Doc for
  existing content at a caller-supplied id, not just the SQL locator —
  closes the gap where an id colliding with content written directly to
  the Y.Doc (bypassing the service layer) would still silently overwrite
  it. Narrower than the reviewer's suggested full reconciliation, which
  is Phase B/C/D-scale machinery already documented as out of scope here.
- catalog_documents/catalog_collections now use a (workspaceId, id)
  composite primary key instead of a bare global id, matching
  record_locator's own (workspaceId, recordId) scoping — a bare id PK
  would let workspace A's locator reservation succeed and then throw an
  unhandled SQL error the moment workspace B tried the same id.

648/648 tests passing (4 new, covering all three fixes).

…hard assignment yet (#120)

Every service function that used to call resolveWorkspaceContext() bare now
resolves its actual target shard via new catalog primitives
(resolveShardForParent/resolveShardForRecord), falling back to the default
context when untracked. createCollection still assigns shardId: 'default'
deliberately — this proves the resolution mechanism correct for a genuinely
separate shard (tests manually construct one, same pattern as the holds
eviction-wiring fix) without changing where content actually lives yet, so
production behavior is unchanged and no client/attach-ws changes are needed
in this slice.

- catalog.ts: reserveRecordLocator/releaseRecordLocator (row-level, closes
  the gap where write_record/delete_record/hold_records only ever receive
  a bare recordId), resolveShardForParent/resolveShardForRecord.
- permissions.ts: resolveParentWorkspaceContext/resolveRecordWorkspaceContext/
  groupRecordIdsByShard — shared resolution helpers; requireAccessibleRecord
  is now itself shard-aware, which every existing caller already goes through.
- records.ts: createRecord reserves a row locator when its parent is a
  Collection; writeRecord/deleteRecord/getRecord resolve via the record's
  own locator.
- collections.ts: queryCollection/updateCollectionTitle/deleteCollection
  resolve the collection's real shard.
- holds.ts: hold_records/release_records group recordIds by resolved shard
  and operate against each shard's own Awareness (a cross-document agent
  batch is a stated acceptance criterion — see collaboration.md).
- search.ts: Collections are enumerated via the catalog first (resolving
  each one's real shard, including its own meta entry — not just its rows),
  with a fallback pass over the default doc for uncataloged (direct-Yjs-
  written) Collections the catalog loop can't see.

No MCP tool schema changes needed — every tool already carries enough of an
id for server-side shard resolution.

661/661 tests passing (13 new).

Refs #120. Branched off feat/workspace-catalog-113-phase-a (PR #119, not yet

…checks

- spaces gains a (workspaceId, id) unique index; catalog_documents/
  catalog_collections/record_locator's spaceId is now a composite FK on
  (workspaceId, spaceId) -> spaces(workspaceId, id) instead of a bare
  spaceId -> spaces.id reference. spaces.id was already globally unique,
  so nothing exploits this today, but nothing in the schema previously
  stopped a row from storing a workspaceId that disagreed with its
  referenced Space's actual workspace either.
- createDocument/createCollection's existing-content check (added for the
  prior "direct Y.Doc write" finding) only checked the same-type map. A
  Collection written directly to the Y.Doc, followed by createDocument
  with the same id, didn't collide there — documentsMap/collectionsMap
  are separate Y.Maps, so it wasn't a literal overwrite, but parentKindOf
  checks documentsMap first, making the original Collection permanently
  unreachable via any parentId lookup. Both creation paths now check both
  maps.

653/653 tests passing (5 new).

Make CRDT and locator updates failure-atomic.

Line 100 reserves the locator after crdtCreateRecord has written the row. If locator reservation rejects the ID or SQLite fails, a row in a non-default shard has no locator. Later record operations fall back to the default shard and cannot find that row.

Deletion has the inverse failure mode. If locator release fails after the CRDT deletion, the durable locator remains stale.

Generate and reserve the record ID before the CRDT write. Add compensation or reconciliation for failures after either side of a dual write.

  • src/lib/services/records.ts#L100-L100: reserve the generated row ID before crdtCreateRecord, and release the reservation if the CRDT write fails.
  • src/lib/services/records.ts#L207-L208: ensure a failed locator release is retried or reconciled so it cannot leave a stale shard mapping.
