Independent review verdict: BLOCKING at df66be1 (lint gate only; the DTO itself is correct)Reviewer: a fresh Claude agent (Sonnet 5.5, high effort), not the author, given a cold brief. It reviewed this PR's own commit ( Blocking (gate)golangci-lint v2.10.1 reports 5 new issues.
Repro: What was verified (clean)
Local verification (fixture-based)
Notes
Next: fix the 5 lint issues as a new commit. The same reviewer will then re-check the delta. |

len(entries) as its capacity before the append loop, while preserving its
initially empty contents and existing filtering behavior.
Review comments at @internal/archera/recommendation_dto_test.go:
- Around line 166-168: Rename the shadowed locals in both subtests around
`contractMatchFixture` and `buildFixture` to avoid the pinned golangci-lint
shadow diagnostics. Keep each subtest’s fresh fixture and update all references
to the renamed contract, items, result, and error variables.
- Around line 227-236: In the hostile-input test around buildFixture, replace
the literal bidirectional control characters in the hostile string and the
NotContains assertion with escaped Unicode representations, preserving the same
test input and assertion.

Preallocate out in vendorEntries.
The enabled prealloc linter can report this unallocated append loop. The ordinary CI workflow runs pinned golangci-lint v2.10.1 over the root module and exits nonzero when lint fails, so this can block CI.

What and why
Adds the recommendation-only response DTO for the per-recommendation Archera comparison (#799 R2, PR2 of the plan).
BuildRecommendationComparisonprojects the vendor comparison and line items, runsMatchRecommendation, and renders only the matched row: one current offer plus its vendor-linked candidates.fetched_at, null currency with the existing currency note, a null comparable delta, and the disclosures.ErrUnrepresentable. A matched result with no vendor row is a fixed error.vendorEntrieshelper (also used byvendorAlternatives), so indexes stay aligned and the current offer is never an alternative.Decimal,CleanStringand the mapper financials helpers; never callsBuildComparison.Tests (synthetic fixtures, no real Archera account)
Distinct monthly/upfront/selected/native/lease values per field; very precise decimals; zero vs null; candidate mismatch; unrepresentable current and candidate; unmatched (source, ambiguous) with no figures; unrelated rows not leaking; hostile vendor string sanitized; input not mutated; current offer in the candidate list (fails with the filter removed).
Mutations (synthetic fixtures, scratch overlay, none in the tree)
20 mutants across every field mapping, the status/provenance/fetched_at/premium/ID rules and index alignment: 20 killed, 0 survived. One extra fail-before probe (drop the
IsCurrentfilter) fails the new test. Null currency and delta have no assignment to mutate; asserted byNilchecks.Verification
