📄 Description

gh pr create --title "fix(kuna): reject version/digest mismatch from replaced executable" --body "## Summary

`inspectKunaInstallation` hashed the executable after the `--version` process exited. A binary that replaced itself in that window produced a success result pairing the old version string with a digest of the new bytes. This PR hashes before and after the probe and returns `version_unresolved` when the digests differ.

Fixes #5611

Problem and expected behavior

Trigger: Any executable that atomically replaces itself between the moment `--version` exits and the moment `hashStableFile` runs.

Violated invariant: `KunaInstallation.sha256` must be the digest of the bytes that produced `KunaInstallation.version`. When the binary is replaced mid-probe, the returned `sha256` belongs to a different build than the one that printed the version string.

Expected: Return `version_unresolved` with `pre_probe_sha256` and `post_probe_sha256` in diagnostics when the digests differ.

Change and scope

Hash the executable with `hashStableFile` once before spawning `execFileOutput` (`preProbeHash`) and once after (existing `fingerprint`). If they differ, return `version_unresolved`. The post-probe fingerprint is still the one returned on success.

Contribution scope: not applicable — ordinary correctness fix within the existing Kuna installation boundary.

Contract and boundary impact

  • Semantic owner and earliest changed stage: `src/kuna/KunaInstallation.ts` — Kuna readiness / provider boundary
  • Contribution scope fit and linked maintainer decision: not applicable
  • CLI and MCP/tool-catalog contract: none — `KunaInstallation` shape unchanged; new failure path uses existing `version_unresolved` code
  • Provider, bridge, target-format, or platform compatibility: none
  • Evidence, artifact, provenance, or reconstruction contract: none
  • Target selection, authority, upstream behavior, and cleanup details: not applicable
  • Generated metadata impact: none

Expected effects:

  • Read existing files or captured data.

Evidence and regression coverage

  • Tests added: `rejects a version/digest pair when the executable is replaced during the probe` in `tests/boundary/providers/kuna/kunaInstallation.test.ts` — gates the fake kuna probe, replaces the binary, releases the gate, asserts `version_unresolved` with differing digests.

  • Base reproduction: source-derived — the TOCTOU window is structural; the new test reproduces it mechanically via the existing `gate` behavior in `writeFakeKuna`.

  • User-visible CLI/MCP output: none under normal conditions; under replacement, `version_unresolved` instead of a silently mismatched identity.

  • Remaining proof gaps: not tested against a real self-updating Kuna release; only fake-kuna path exercised.

  • 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 + lint)
  • `npm run test:local -- tests/boundary/providers/kuna/kunaInstallation.test.ts` — could not run on Windows; native artifacts missing; requires POSIX or CI

Compatibility, safety, and release

  • Breaking changes or migration steps: none
  • Real Hopper/Ghidra, browser, or OS coverage: not applicable
  • Package or release metadata impact: none
  • Security, privacy, process, or containment review: none
