[TheGreatAxios]

Replays a full Builder project end to end against a real Hub, Postgres, sidecar and workspace sandbox without calling a live model provider.

• test/e2e/support/recorded-model.ts serves an OpenAI-compatible /v1/chat/completions SSE endpoint backed by recorded exchanges under test/fixtures/pipeline/. Each request matches its expect.json structurally by run kind, ordered tool declarations, user/tool turn shapes and required tool-result substrings, captures runtime values (approvalId, appUrl) from tool results and substitutes {{bind:<key>}} placeholders in streamed tool call arguments. Any divergence fails with the scenario, stage, run, exchange index and re-record instructions.
• test/e2e/pipeline.test.ts drives the animated weather app through the planning documents (problem_brief, constraints, approaches v1, reviewer revision to approaches v2, product_requirements), the three-screen HTML design (check_design in headless Chrome), build_plan, the coder (app_status, Playwright browser_* checks, bun test, git commit) and the built app (v1 from starter setup and v2 after the coder commits, fetched via GET /api/projects/:id/app, extracted and verified with bun test), asserting each stage's Hub state and the ordered runs and artifacts sequences against manifest.json.
• apps/hub/src/builds/posix-sandbox.ts, apps/hub/src/builds/sidecar-tools.ts and apps/hub/src/live-app/host.ts pass --conditions=intx-src to the sandboxed tool child, keep TMPDIR pointed at a writable directory inside wrapped commands while denying writes to /tmp/claude, allow the Linux proxy bridge Unix sockets in allowRead, relay the dev app over a Unix socket across Linux sandbox network namespaces (createAppRelay with bwrap mount/PID isolation), enable allowAllUnixSockets on Linux for sidecar-owned browser/relay helpers after wrapping the agent tool child, and prefix Linux sandbox wrappers with exec so kill terminates the bubblewrap namespace owner directly.
• apps/hub/src/middleware/correlation.ts attaches requestContext as contextLocalStorage when LogTape was initialized with the default sink before setupHubLogging().
• .github/workflows/ci.yml keeps e2e on the fast tests (custom-provider, oauth-model-login, specialist-end-notices, recorded-model) and runs test/e2e/pipeline.test.ts in its own e2e-pipeline job (continue-on-error: true).
• test/AGENTS.md documents the test layout, how recorded replay works and how to update or re-record fixtures when prompts, tools or starter files change.

Verified with bun run format:check, bun run lint, bun run typecheck, bun run test, bun --conditions=intx-src test ./test/e2e/support/recorded-model.test.ts, bun --conditions=intx-src test ./test/e2e/pipeline.test.ts, bun run pins:verify and bun run vendor:verify.
