Validation Report: Issues #578 and #579

Status: Conditional Approval (functional acceptance passed for scope; quality follow-ups open) Date: 2026-02-24 Research Doc: docs/plans/issues-578-579-research-2026-02-24.md Design Doc: docs/plans/issues-578-579-design-2026-02-24.md Verification Report: docs/reports/issues-578-579-verification-report-2026-02-24.md

Executive Summary

The implemented changes validate the intended user outcomes for ticket scope:

  • #578: terraphim-agent search now supports machine-readable output contract in robot/json modes.
  • #579: TerraphimGraph search now has lexical fallback when graph query is empty.

Validation is conditional because UBS summary reports unresolved critical findings in terraphim_service scan output and strict clippy remains blocked by pre-existing workspace warnings.

System Testing Results

End-to-end scenarios

| ID | Workflow | Expected Outcome | Result | Status | |---|---|---|---|---| | E2E-578-1 | terraphim-agent --robot search <query> --limit N | Parseable JSON with query, role, count, results | Verified by integration tests | PASS | | E2E-578-2 | terraphim-agent --format json-compact search ... | Compact JSON machine output | Verified by integration tests | PASS | | E2E-579-1 | TerraphimGraph with no graph term match but lexical haystack hit | Non-empty results via fallback | Verified by dedicated fallback integration test | PASS |

NFR/System checks

| Category | Tool/Method | Result | Status | |---|---|---|---| | Static bug scan | UBS (--diff --only=rust) | Agent: 0 critical; Service: 4 critical (summary) | CONDITIONAL | | Formatting | cargo fmt | clean for touched packages | PASS | | Linting | cargo clippy -p terraphim_agent -p terraphim_service -- -D warnings | blocked by pre-existing terraphim_types warnings | CONDITIONAL |

Acceptance Testing (UAT-style)

Acceptance Criteria

| Ticket | Criterion | Evidence | Status | |---|---|---|---| | #578 | search respects machine mode with --robot and --format json* | robot_search_output_regression_tests.rs | Accepted | | #578 | no TerraphimGraph banner pollution in machine contract | service banner removal + JSON parsing tests | Accepted | | #579 | graph-empty false-zero fixed via lexical fallback | terraphim_graph_lexical_fallback_test.rs | Accepted |

Requirements Traceability

See:

  • docs/reports/issues-578-579-traceability-matrix-2026-02-24.md

Defects and Loop-back

| ID | Defect | Classification | Loop-back | |---|---|---|---| | VAL-1 | UBS critical findings in service scan summary | Verification/implementation quality | Phase 3 triage/fix | | VAL-2 | Pre-existing clippy blockers in workspace | Technical debt outside ticket scope | Phase 3 debt cleanup |

Stakeholder Acceptance Summary

Stakeholder instruction accepted progression through implementation and requested verification/validation reports and ticket traceability updates. Formal production go/no-go remains conditional on closing VAL-1 and VAL-2.

Final Validation Decision

Pass with Follow-ups (Conditional) Functional scope for #578 and #579 is validated; final quality gate requires triage/closure of outstanding scanner/lint follow-ups.
