Observed writing choices, not acceptance rules. This study examines the inspected manuscript version. It does not establish why the paper was accepted or that its presentation choices should be copied unchanged.

Figure, table and section ledger

Editorial contribution type: Architecture & representation (primary).

Layout extraction, not a required paper template. Counts are distinct caption labels; a multi-panel figure counts once. Section spans are estimated from heading positions, including floats and whitespace. Method and limitations.

Extraction notes: No attached appendix boundary detected. Zero means no recognized caption, not independently verified absence.

Section-by-section lengths and source pages

The title/abstract/front matter precede the first numbered heading. A span ends at the next detected top-level heading, not at the last sentence; end-page whitespace is included. References and statements are listed separately. These are not measurements of text-only or artwork area.

Separate source files—excluded from canonical-PDF totals

A separate author version may repeat main text and references. Whole-file lengths and counts are not extra appendix material and are never added to the canonical PDF totals. Read the study's source scope for which sections received substantive reading versus layout inspection.

Separate PDF (or ZIP containing it): whole-file layout of 9 physical pages; 4 detected figures and 2 tables. These may include overlapping main-text material.

Located appendix only: starts on physical p.1; ≈ 8.93 page-equivalents, 4 figure labels and 2 table labels. This interval is distinct from the whole file.

Argument and organization

1. Problem and contribution

   Identifies a concrete exploitable property of neighboring obfuscating lines rather than claiming previous methods fail without mechanism.

2. Argument sequence

   Introduces lifted-point localization and the recovery attack before the proposed line geometry and pose-estimation procedure.

3. Evidence and verification

   The evaluation separates recovered-point/image quality from localization accuracy and discusses additional server-side access.

Clarity and writing conventions

A compact capability table precedes the detailed related-work discussion, but later numerical tables provide the actual comparison.

What to reuse—and what not to infer

Transferable lesson: Explain the adversary's mechanism before the defense and show retained task utility as a separate claim.

Boundary: Resistance to the tested recovery procedures is not a universal privacy guarantee; retain server access and descriptor assumptions.

Apply this lesson using the argument and evidence worksheet.
