Worth a look — the grounded gate found no coupling regressions or blocking issues, but 3 advisory finding(s) below merit a look before merge.

Graphify review — findings

Streams XLSX export from the local SQLite viewer in 10k-row query chunks (yielding to the event loop between batches) instead of loading every row at once, so large tables export without blocking the UI. Adds a row-count control letting the user pick how many rows to export or select "all", caps the total at XLSX_MAX_ROWS, and names the download <table>-<n>-linhas.xlsx. Updates the file-size guidance copy to mention the SQLite WASM in-memory limit.

• Concurrent file opens can publish a stale database and leak the newer one — src/components/db/local-db-viewer.tsx:43 · Escalate · medium
  • agreed by 2 of 2 members but NOT verified (no proof, no reproducing execution) — consensus is not a verdict; needs human review

Analysis details — impact, health, verification

Impact & health

Graphify review

Impact — 7 functions depend on the 7 functions this change touches.

Health — grade A; no new coupling hotspots.

Verification — 7 functions in the blast radius were not formally verified this run (proofs are advisory here).

Gate & verification

graphify gate

PASS — objectively clean (no health regressions, tests not run — proofs not run this pass (advisory)). Grounded, not self-assessed.

Advisory (not blocking):

• verification_scope: 7 function(s) in the blast radius were not formally verified this run
