Purpose

Make the large-files result usable and understandable with assistive technology and a keyboard: name the table, bind column headers, expose overflowing rows as a named keyboard-scrollable region, and replace an empty table with a clear next action. Scan data, visible file paths, sorting, byte formatting, navigation, and filesystem authority remain unchanged.

Exact current state

  • independently resolved live main: 5f7c7ae38adafd1f3b3640016a8333767c89d78a
  • exact current head: 9d573f04145eb4168098623042484fdf73c2ab74
  • the branch was non-destructively converged onto live main with a two-parent merge; fresh main -> head comparison is ahead-only, behind_by = 0, and the merge base is exactly live main
  • the effective semantic delta against live main remains exactly src/lib/TopFiles.svelte plus src/lib/topFilesAccessibilityContract.test.ts; all four newer main-side dependency commits are preserved in the resulting tree
  • PR remains open, Draft, and GitHub reports it mergeable; Draft/mergeable state is not merge authorization
  • fresh exact-head Test 32660726478, Release 32660726533, Security Scan 32660726515, and SAST Semgrep 32660726607 are queued and therefore non-passing
  • predecessor workflow success and predecessor review evidence do not transfer to this converged head

Test-first accessibility repair retained on the converged head

  • RED head d37ad25d6544214110d3a36128ee477aafe849ba first required a programmatic table name and explicit column scopes while protected main exposed neither.
  • The visible heading has stable id top-files-heading; the table derives its accessible name with aria-labelledby="top-files-heading"; both headers declare scope="col".
  • A later focused RED proved the 40vh overflow was attached to the entire section, leaving the rows without a dedicated sequential keyboard-scroll target, and that an empty result still rendered a structurally empty table with no next action.
  • Current implementation moves overflow to a role="region", tabindex="0" wrapper named by the same heading, includes a visible .table-scroll:focus-visible outline, and renders 표시할 대용량 파일이 없습니다. 다른 폴더를 스캔하거나 스캔 범위를 넓히세요. as a status message when no files are present.
  • The focused contract asserts the heading/table relationship, column scopes, named keyboard-scroll region, focus indicator, and action-oriented empty state.

Existing row text, customer-visible file paths, file-size values, sticky headers, scan data, sorting, navigation, and filesystem authority are unchanged.

Stale convergence proof

Before converging, fresh comparison showed this branch was 8 commits ahead and 4 commits behind live main with merge base 93aa7477629753187da101a8af0e7276480f1a86. Fresh 93aa747... -> main comparison showed the four main-side commits changed only package.json, package-lock.json, and src-tauri/Cargo.lock; they did not overlap either TopFiles accessibility file. The current merge tree therefore starts from the exact live-main tree and overlays only the two existing feature blobs, preserving every main-side file while retaining the complete unique accessibility delta. The branch ref was advanced with force: false; no rebase or history rewrite was used.

Review and governance boundary

The earlier CodeRabbit request to contract-test the focus indicator is satisfied by current source, but its predecessor review is not current-head approval. Reacquire review evidence as required after the head move. Repository-wide exact 100% owned-production region/statement-equivalent, branch, function, and line coverage remains owned by Draft #156 and is not satisfied by this feature-local lane.

Live main still reports protected: true while the effective branch-protection payload has required-status enforcement disabled and required checks empty; governance restoration remains tracked by #248. This PR must not infer merge authority from the protection badge, mechanical mergeability, or predecessor green checks.

Scope / non-duplication

This lane owns only src/lib/TopFiles.svelte and its focused accessibility contract. It does not modify src/routes/+page.svelte owned by #202, Treemap accessibility #196, repository-wide coverage #156, canonical documentation #149, or cleanup/cloud/provider authority.

Required before merge

Keep Draft until one unchanged latest head satisfies every applicable live Test/Release/Security/SAST/coverage/package/review gate, every valid current finding/thread is resolved, effective branch/ruleset enforcement is actually live, fresh base ancestry remains current, repository-wide exact coverage is satisfied without exclusions or threshold weakening, and any qualifying independent latest-push approval required by policy is present. Pending, queued, skipped-required, neutral-required, failed, stale, predecessor, synthetic, diagnostic-only, status-only, model-only, author-only, rate-limited, no-source-scanner, or infrastructure-only evidence is non-passing.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to a3f90

This localized accessibility change names the table, binds its headers, supports keyboard access to overflowing rows, and provides a clear empty state without changing file data or navigation behavior; no actionable merge-blocking risk remains beyond normal checks and review.
