Two-tab remote-subset browser oracle

  • Reviewed oracle commit: 15301fd409fdebdc84eebbbf0ae9e1f095b3b26c
  • Comparison main: d3c38c8f4e83cef4545e8011dc3419be1fcf527a
  • Owner: packages/browser-db-sqlite-persistence/e2e/remote-subset-two-tab.opfs.spec.ts
  • Runtime: real Chromium, two same-origin pages, one OPFS database, QueryClient-backed on-demand source, filtered live-query Collection
RequirementOutcome
ORC-001Pass within the stated scope. The browser coordinator's documented remote-subset contract keeps live signal and subscription references local while it transports clone-safe request data. Issue #1498 supplies the two-tab failure history. The test does not run React, Firefox/Zen, or a live backend.
ORC-002Pass. The fixed query input independently specifies the one expected public row and label. Neither the coordinator's transport projection nor its response computes that expectation.
ORC-003Pass for a fixed history. The test header states the law, model, history, driver, checkpoint, and limits. The adjacent fixture drives the real QueryClient, Collection, coordinator, BroadcastChannel, and OPFS path.
ORC-004Not applicable. This test executes one deterministic two-tab history. It makes no generated-history grammar claim.
ORC-005Pass. The follower's load carries where, signal, and a callback-bearing subscription. A remote-subset RPC post occurs, the follower makes no upstream Query call, and its public live-query row matches the fixed input after preload. An invalid nested function fails with its exact wire path before another post.
ORC-006Pass. A temporary mutant stored raw options instead of transportedOptions in the outbound acquisition. The focused test failed at follower readiness with four DataCloneError posts for the AbortSignal. This reached the intended browser path; it was not a setup failure or timeout. The mutant was removed, and the focused test passed again at the reviewed commit.
ORC-007Not applicable. This is not an important generated property.
ORC-008Not applicable. The fixed expected row adds no stateful reference model.
ORC-009Pass. The source and live-query Collection names follow the glossary. The follower post is a transport observation, not evidence that every provider request or browser host works.
ORC-010Pass. The test closes both pages and calls fixture cleanup. It keeps a primary mismatch separate from each cleanup error through an AggregateError cause and errors. It does not shrink or normalize a history.
ORC-011Not triggered. No plausible semantic fault shared by the fixed input model and transport implementation requires a second formulation. React rendering, Firefox/Zen, and a live backend remain unverified host boundaries.
ORC-012Pass. This versioned record accounts for ORC-001 through ORC-011 against the exact oracle commit above.

At the reviewed commit, the complete Chromium OPFS suite passed 3/3 tests. The package TypeScript check, ESLint, Prettier, and git diff --check passed. The local pre-commit hook could not start pnpm lint-staged because pnpm tried to replace the worktree's linked dependency directory. Equivalent ESLint and formatting checks ran directly before the normal commit.
