fix(base): verify null numeric record-list cells

[AiniTang]

A rare matrix response from base +record-list can contain null for a populated Number/Currency cell while the record batch-get endpoint returns the stored value. Because the command currently accepts the matrix response as-is, downstream totals can be silently understated.

This change treats null numeric cells as ambiguous and verifies only those cells through records/batch_get. It reconciles by stable field ID, keeps confirmed legal nulls unchanged, and returns a typed invalid_response error when verification omits a record/field, reports record_not_found, or returns a conflicting revision. Verification is chunked to the API's 200-record and 100-field limits. Responses that do not expose revisions remain compatible; when both endpoints expose revisions, they must match.

Validation:

• go test ./shortcuts/base/...
• make fmt-check
• make vet
• make unit-test
• QUALITY_GATE_CHANGED_FROM=origin/main make quality-gate
• Live read-only smoke test against a 357-row table: both pages returned the same revision and a known populated currency cell returned its stored value

Summary by CodeRabbit

• Bug Fixes
  • Improved record-list reliability by recovering missing numeric and currency values that may appear as null.
  • Preserved legitimate null values while validating and restoring silently missing number cells.
  • Added safeguards for incomplete, malformed, or inconsistent record responses.
  • Improved handling of large result sets by validating and repairing missing values in batches.

📝 Walkthrough

Walkthrough

Record-list execution now verifies null number and currency cells through batched batch_get requests. It validates response structure and revisions, repairs verified values, and adds coverage for batching, legacy responses, and invalid responses.

Changes

Record list consistency

Layer / File(s)	Summary
Verification matrix and parsing contracts shortcuts/base/record_list_consistency.go	Adds internal response structures and strict parsing for fields, records, rows, types, revisions, and not-found records.
Null number-cell verification shortcuts/base/record_list_consistency.go	Detects null number and currency cells, fetches affected records and fields in batches, validates responses, and writes verified values into the list result.
Record-list integration and validation shortcuts/base/record_ops.go, shortcuts/base/record_export.go, shortcuts/base/record_list_consistency_test.go, shortcuts/base/base_execute_test.go	Routes record-list paths through verification and tests repaired values, preserved nulls, legacy responses, malformed responses, revision changes, and batching limits.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to a2c00

Record listing now verifies ambiguous null number and currency cells with batched record reads while preserving legal nulls and returning typed errors for inconsistent responses. No concrete merge-blocking risk remains.

In `@shortcuts/base/record_list_consistency.go`:
- Line 133: Update the matrix verification flow around verifyNullNumberCells so
parsing failures for matrices with all required keys return the typed
invalidRecordVerificationMatrix error instead of converting the parse error to
false and emitting malformed data. Preserve the existing missing-legacy-key
behavior for absent keys, and ensure the command-facing failure uses the
established errs.* error type.
- Line 52: Update the field-type check in the record-list consistency logic to
include currency alongside number so populated Currency cells are verified
through batch_get. Add a nearby regression test covering a populated Currency
cell that would otherwise remain null.

Addressed both review findings in a2c0053:

• Currency nulls now follow the same batch-get verification path as Number nulls, with a regression test for value repair.
• A matrix with all required keys but malformed content now returns the established typed internal/invalid_response; only responses missing legacy keys keep the compatibility fallback.

Revalidated with focused Base tests, fmt, vet, the full race-enabled unit suite, quality gate, and a live read-only 357-row smoke test.
