📄 Description

Summary

Recovers tRPC HTTP link URLs whose options are declared with expression-free template literals (e.g. httpLink({ url: /api/template })). Isolates the remaining producer fix and RPC-link regressions from #2805 after route and dynamic-import template handling landed on main in 88afcc738.

Problem and expected behavior

When recovering client-side transport URLs in javascriptRpcEndpoints.ts, trpcLinkUrl extracts the url property using semanticFinalObjectStringProperty(options, "url"). Previously, semanticFinalObjectStringProperty strictly checked t.isStringLiteral(value).

As a result, constant transport URLs declared as expression-free template literals (such as (0, t.httpLink)({ url: /api/template }) or httpBatchLink({ url: /trpc/template })) were dropped rather than captured as network endpoints (trpc:link:<factory>).

Expected behavior: Transport URL options declared as expression-free template literals should be extracted with their exact string value, while dynamic interpolated templates remain unknown.

Change and scope

  • Update semanticFinalObjectStringProperty in src/domain/javascript/javascriptAstValues.ts to use readExactJavaScriptLiteral(value) so that expression-free template literals are resolved to their exact string values without accepting dynamic interpolations or non-string primitives.
  • Note on scope: As semanticFinalObjectStringProperty is a shared helper, constant expression-free template literals also resolve when reading GraphQL operation properties (kind, operation, name.value).
  • Add unit tests in src/domain/javascript/javascriptRpcEndpoints.test.ts verifying constant and interpolated template literal link URLs across object-property ownership tables and bundled factory wrappers.
  • Add regression coverage in tests/acceptance/applications/javascriptRpcPropertyOwnershipCli.test.ts validating that template literal RPC options are retained in both CLI and stdio MCP graphs.

Contract and boundary impact

  • Semantic owner and earliest changed stage: AST inspection in src/domain/javascript/javascriptAstValues.ts.
  • Contribution scope fit and linked maintainer decision: Follows maintainer review on #2963 to isolate the unmerged RPC link producer fix and regression coverage from #2805.
  • CLI and MCP/tool-catalog contract: Unchanged schema; improves recall for constant RPC link endpoints.
  • Provider, bridge, target-format, or platform compatibility: Pure static AST analysis; platform-independent.
  • Evidence, artifact, provenance, or reconstruction contract: Preserves exact coordinates and trpc:link:* mechanisms.
  • Target selection, authority, upstream behavior, and cleanup details: Read-only static AST analysis.
  • Generated metadata impact: None.

Expected effects:

  • Read existing files or captured data.
  • Launch or attach to a process.
  • Inject instrumentation or run scripts/code.
  • Change process memory, registers, files, or configuration.
  • Contact network services.
  • Recover protected code or work around protections.
  • Documentation or usability only; no target interaction.
  • Not sure yet; investigation or maintainer guidance needed.

Evidence and regression coverage

  • Tests added or updated:
    • src/domain/javascript/javascriptRpcEndpoints.test.ts: Added table test cases covering constant template literals, final overrides, and rejected interpolations in RPC link options, as well as template literal URL recovery in bundled call wrappers.
    • tests/acceptance/applications/javascriptRpcPropertyOwnershipCli.test.ts: Added fixture and assertions verifying template literal link URLs through CLI and stdio MCP analysis.
  • Base reproduction: Base revision dropped { url: /api/template } link options.
  • Remaining proof gaps: None.

For evidence-bearing changes:

  • Observed, derived, and inferred claims remain distinguishable.
  • Artifact identity, source provenance, and failed attempts remain preserved.
  • Unsupported, incomplete, unavailable, or uncertain outcomes remain visible.

Validation performed

  • npm run check:fast — passed (typecheck and lint)
  • npm run format:check — passed (oxfmt)
  • npm run verify:module-boundaries — passed (1928 source files checked)
  • npm run verify:test-discovery — passed (1326 test files verified)
  • npm run test:focused -- src/domain/javascript/javascriptRpcEndpoints.test.ts tests/acceptance/applications/javascriptRpcPropertyOwnershipCli.test.ts — passed (102 tests passed)

Compatibility, safety, and release

  • Breaking changes or migration steps: None.
  • Real Hopper/Ghidra, browser, or OS coverage: Pure domain AST analysis.
  • Package or release metadata impact: None.
  • Security, privacy, process, or containment review: Pure static analysis; no execution or mutation authority.
