📄 Description

Summary

Fixes #4375. Preserve Hopper startup diagnostics when the same typed error also carries provider-neutral diagnostic context.

Problem and expected behavior

projectAnalysisError first projected HopperProcessError.diagnostic into details.diagnostics, then replaced that object with AnalysisError.diagnostics. A private-display startup diagnostic therefore disappeared when caller or secondary-failure context was also present. Both sets of caller-safe facts should remain available.

Change and scope

At the shared error-projection boundary, merge an object-valued primary diagnostic with generic diagnostics before constructing the final details. Generic keys retain their existing precedence on collisions. Provider-only projections and non-object primary diagnostic behavior stay unchanged.

Follow the contribution scope. This is an ordinary fix within the existing typed error-projection boundary; a separate maintainer scope decision is not applicable.

Contract and boundary impact

  • Semantic owner and earliest changed stage: projectAnalysisError, typed error projection.
  • Contribution scope fit and linked maintainer decision: ordinary bug fix within an existing boundary; not applicable.
  • CLI and MCP/tool-catalog contract: existing projected errors can now retain both startup and generic fields in details.diagnostics; schemas and tool catalogs are unchanged.
  • Provider, bridge, target-format, or platform compatibility: no provider execution changes; the recovered fields originate from Hopper startup failures.
  • Evidence, artifact, provenance, or reconstruction contract: preserves caller-safe diagnostic provenance that was previously dropped.
  • Target selection, authority, upstream behavior, and cleanup details (if applicable): cleanup enrichment is preserved without changing ownership or retry behavior.
  • Generated metadata (docs/public/product-catalog.json), package, or installation impact: none.

Expected effects (check known effects; use documentation-only on its own).

  • 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: added a Hopper startup projection regression covering the provider-only control, constructor-supplied generic context, and retainSecondaryFailure enrichment.
  • Base reproduction or other evidence: on d72d856f58d4747c5eb4307426e80d20934e017c, the new focused test failed because the projection contained only { caller_context: "retained" } and omitted all startup fields.
  • User-visible CLI/MCP output (if applicable): projected details.diagnostics now contains the retained startup facts alongside generic context; no compiled CLI/MCP run was performed.
  • Remaining proof gaps: no real Hopper startup failure was run. The issue's production-parser reproduction and existing boundary coverage establish the diagnostic shape; this change was verified at its domain projection owner.

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

  • Regression test before the fix — failed with expected { caller_context: 'retained' } to deeply equal the combined startup and generic diagnostics.
  • npm run test:focused -- src/domain/analysisErrorProjection.test.ts — 55 tests passed.
  • npm run check:fast — typecheck and lint passed, including module-boundary verification.
  • node scripts/verify/architecture-guards.mjs with Node 24.18.0 — passed across 1,455 source files.
  • oxfmt --check src/domain/analysisErrorProjection.ts src/domain/analysisErrorProjection.test.ts — passed.
  • git diff --check — passed.
  • npm run check with Node 24.18.0 — unavailable because this clone lacks native/windows/build/manifest.json and native/windows/build/rea-windows-x64.node; the command stopped in the native-artifact precheck before repository checks ran.

Compatibility, safety, and release

  • Breaking changes or migration steps: none.
  • Real Hopper/Ghidra, browser, or OS coverage: no real provider run; Windows domain tests and static checks only.
  • Package or release metadata impact: none.
  • Security, privacy, process, or containment review: merges already validated caller-safe JSON diagnostics; no new data collection, process launch, or authority.

Author readiness

Human owner: @ericbyz

  • I reviewed the final diff and relevant existing code, understand the change and its edge cases, and take responsibility for the complete PR, including AI-assisted work.
  • I checked the evidence above, confirmed it supports the current change, and recorded meaningful validation gaps.
  • I declare this PR ready for initial maintainer review.

Before merge

  • This PR addresses a concrete problem or an agreed enhancement.
  • Material scope and authority questions are resolved, and any required maintainer scope decision covers the final diff.
  • The PR has one focused outcome and the title follows type(scope): outcome.
  • Related issue is linked, or the reason for not linking one is stated above.
  • Tests cover changed observable behavior and meaningful failure paths.
  • Owning docs, contracts, and generated metadata are updated where needed.
  • User-visible CLI/MCP changes include representative output.
  • I checked the final diff for secrets, unrelated cleanup, and unsupported claims.
