Summary

  • Remove the /sandbox route: deletes frontend/src/app/sandbox/** (page, client, OG image, /sandbox/results/[id]). Drops the sitemap entry and the /sandbox marketing-analytics section. sandboxCta() never returns /sandbox now.
  • /compare links: /compare itself returns 404. No bare links to it exist on current main. compare/* pages are left as they are.
  • Drill simulator: "Download Sample CSV" is now "Download CSV template". It downloads traceability-records-template.csv with the header row only and no example records. The tool itself stays.
  • Removes tests that only covered the deleted route: sandbox-front-door.test.tsx, sandbox-shared-result-base-url.test.ts and e2e sandbox-front-door.spec.ts. tests/visual/routes.json already expects /sandbox to 404.

Out of scope (owned elsewhere)

Checks

  • tsc --noEmit: one error in src/instrumentation.ts (queues). That file was not touched, so the error comes from main or from the installed dependencies.
  • eslint on the touched files: clean.
  • vitest: the drill and sandbox-diagnosis tests pass. marketing-analytics-routes.test.ts fails the same way on unmodified main locally (cookie env), so CI decides.

Note

Medium Risk
Removes a public marketing route and changes primary CTA destinations to /ingest, which can break bookmarks and external links; drill simulator download behavior changes for users expecting filled sample data.

Overview
Retires the public /sandbox experience and routes “try your CSV” marketing CTAs to /ingest instead of /sandbox or /demo. The change deletes the Next.js sandbox app (page, upload client, OG image, shared /sandbox/results/[id]), related diagnosis/PDF UI, sitemap advertising, and the sandbox front-door unit/e2e tests.

sandboxCta() is simplified so it always returns enabled: false with copy and link aimed at CSV upload on /ingest, even when the experimental backend sandbox router is on. Marketing analytics drops /sandbox from trackable public sections (sensitive /sandbox/results paths stay excluded); one test no longer expects bare /sandbox pageviews to track.

Drill simulator replaces “Download Sample CSV” with “Download CSV template” — a headers-only traceability-records-template.csv via new generateCsvTemplate() — while in-browser sample loading is unchanged.

Walkthrough

The public sandbox landing page, client, Open Graph image, and shared-result pages are removed. The sitemap, marketing-path allowlist, and CTA no longer expose the sandbox route. Related sandbox test coverage is removed or updated. The drill simulator now downloads a header-only CSV template with a template-specific filename and label.

Priority: Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Low · up to b63b7

The sandbox retirement appears mergeable. The CSV template does not show the optional TLC Source field, so users who need it must add the column themselves.

Security architecture risk: Low · up to 059da

The change removes public sandbox pages and directs CSV upload links through the existing sign-in boundary. No new privilege or data-access expansion was established. Removing the pages does not establish that the underlying sandbox service is disabled.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The demonstrated propagation is across frontend marketing entry points into an existing authenticated application route. The inspected comparison does not establish an increase in backend authority, tenant scope, or data-store access.

Trust Boundaries and Controls

  • observed — The new CTA destination /ingest is classified as an authenticated application route. Existing request handling applies application authentication and redirects unauthenticated visitors to login; the PR does not remove those controls.

Template download lacks tests

Low Severity

generateCsvTemplate and the "Download CSV template" path are new behavior, but there is no test that the file is headers-only or that those headers still match the drill parser.

Expose tlcSource in the template if it should cover all parsed fields.

COLUMN_MAP and PARSED_RECORD_FIELDS support tlcSource, but REQUIRED_KDES does not require or validate it. The sample CSV also omits TLC Source. The current omission only prevents users from supplying this optional parsed field through the generated template.

CTA copy mismatches ingest destination

High Severity

sandboxCta() now promises a CSV FSMA 204 check, but href is authenticated /ingest. Public compare and homepage visitors hit a login redirect, and even a signed-in user lands on the URL tab rather than CSV upload. /ingest persists tenant data instead of evaluating a file like the retired sandbox.

REVIEW: PASS grok 059da16

Re-scoped verdict. My earlier draft failed this head only because the drill simulator Load Sample Data button (DrillSimulatorClient.tsx:212-216, 492-494) calls generateSampleCSV() with invented records. C.Lee decided to keep the drill simulator sample data as a recall-simulation exception, so that is out of scope here.

In scope and verified: frontend/src/app/sandbox/** removed with no leftover imports or /sandbox links; sandboxCta() returns /ingest (Upload your CSV); /sandbox dropped from marketing routes and sitemap; generateCsvTemplate() is header-only.

Nits: tests/visual/routes.json notes still say /sandbox and /demo return 200; /ingest needs sign-in. tsc and vitest were not rerun locally because of high Mac load; rely on CI.

Posted with C.Lee's approval (Oct 23, 2026, 7:18 PM PT).
