From 117270338952e7f7c1684600fdc7962eb72166ae Mon Sep 17 00:00:00 2001
From: Mohit Gupta <mohgupta@nvidia.com>
Date: Thu, 10 Sep 2026 11:57:21 +0530
Subject: [PATCH 01/12] fix: avoid false analysis limits in documentation

Distinguish Markdown code delimiters from shell substitutions during coverage checks, and reject JSON value closers as fallback removal-marker openers. Add documentation regressions and preserve shell reconstruction coverage across scripts and Markdown code blocks.

From: Mohit Gupta <mohgupta@nvidia.com>
Date: Thu, 10 Sep 2026 16:15:51 +0530
Subject: [PATCH 03/12] fix: preserve literal syntax in list and HTML blocks

Keep list-relative indentation and HTML block terminators when identifying Markdown delimiters. Exercise incomplete-result gates with and without semantic analyzers. Prepared by Codex on behalf of Mohit Gupta.

Subject: [PATCH 08/12] fix: respect JSON strings and Markdown block boundaries

Recognize structural quotes in bounded, validated JSON arrays, objects,
scalar strings and explicit JSON fences, including container prefixes and
frontmatter bodies. Preserve source offsets and linear, cancellable scanning.

Keep inline delimiter pairing within Markdown blocks so separate list items
and headings cannot hide unresolved runtime commands. Retain genuine command
findings, incomplete coverage and existing advisory risk policies.

Add tests-first reviewer reproductions, neighboring JSON and Markdown
controls, linear-work/deadline checks and inline Make reference regressions.
Exercise CLI and MCP with deterministic enabled/disabled LLM transports.

Prepared by Codex on behalf of Mohit Gupta.

Subject: [PATCH 09/12] test: cover Markdown table and JSON ownership
 boundaries

Add tests-first reproductions for table row and cell boundaries, tab-column JSON containers, hidden runtime commands and bounded owned-string recovery. Preserve benign documentation, raw findings, strict CLI and MCP coverage gates in enabled and disabled LLM transport modes.

Prepared by Codex on behalf of Mohit Gupta.

 gates

Retain complete and installable benign table exits in both semantic modes, and reproduce empty-list items incorrectly opening a paragraph before the next table header. Preserve red evidence before correcting that state transition.

From ca0ceb77e252c0ad5dc84eb435323edb80d28c57 Mon Sep 17 00:00:00 2001

Subject: [PATCH 12/12] fix: preserve table cells and tab-indented JSON
 ownership

Keep inline delimiters within proven table cells and respect contextual header, row and block boundaries. Interpret JSON container indentation in visual columns while preserving raw source offsets. Recover skipped runtime JSON strings through disjoint projected spans without overlapping suffix parses or changing raw finding evidence.

Validated against tests-first regressions, documentation and JSON overlap tests, GFM reference cases, bounded-work checks and enabled/disabled CLI/MCP transport modes.

Prepared by Codex on behalf of Mohit Gupta.
