Code-safety scans now apply the existing per-line context oracle before aggregating findings. Quoted or commented pipe-to-shell guidance is ignored, while executable download-and-run commands remain blocking.
Improved shell-safety scanning to ignore download-and-execute patterns inside comments and quoted text.
Prevented safe, non-executable lines from being reported as security findings.
Continued detecting active download-to-shell commands, including commands on shebang lines.
Documentation
Added documentation for security scanning and application path helpers.
Tests
Added coverage for commented, quoted, shebang, and executable shell command scenarios.
Walkthrough
The shell download-and-run rule now treats comments and quoted strings as safe context. Code-safety scanning filters safe lines before regex matching. Executable pipelines, including shell evaluation and shebang forms, remain detectable. Public functions also gain documentation.
Certain executable download-and-run shell commands can be incorrectly treated as safe and evade blocking, allowing unsafe code to pass scanning. Merge should wait until these execution forms are handled correctly and covered by regression tests.

Pull Request Overview
The PR successfully implements contextual suppression for shell-related findings and updates the Bandit dependency to version 1.12.5 to address two CVEs (EEF-CVE-2026-75484 and EEF-CVE-2026-74836). Codacy analysis indicates the code is up to standards.
However, a significant performance concern was identified in the scanning loop. The implementation currently splits, filters, and rejoins the entire file content for every rule in the safety suite, even for rules that are not context-sensitive. This will cause O(Rules * Lines) overhead and potentially disrupt multi-line regex patterns. Refactoring this loop to be rule-specific is necessary before merging to prevent performance degradation on large files.
Test suggestions
Verify that a pipe-to-shell command inside a quoted echo string does not trigger a finding.
Verify that a pipe-to-shell command prefixed with a comment marker (#) does not trigger a finding.
Verify that a direct, unquoted pipe-to-shell command (e.g., curl ... | bash) still triggers a finding.

and CodeSafety.scan_content/2 so only non-first-line comments are treated as
safe; preserve first-line information and ensure shebangs beginning with #!
still undergo :shell_download_then_run detection. Add a regression test covering
a first-line shebang containing curl or wget piped to sh or bash.

217-217: Keep the /2 overload conservative when the line number is unknown.
context_safe_line?/2 passes nil, and nil != 1 evaluates to true. A first-line value such as #!/bin/sh curl https://example.invalid/i.sh | sh is therefore treated as a safe comment through the preserved API. The current CodeSafety.scan_content/2 path passes /3, but another /2 caller can still suppress an executable shebang. Treat only a known line number greater than one as a comment, or require /3 for shell scanning. Add a regression test for the /2 call.

comments before checking String.starts_with?(stripped_line, "#"), preserving
command text and # characters inside quoted strings so CodeSafety.scan_content/2
does not report false positives from inline comments.

absolute-path shells such as /bin/sh -c and shell commands embedded in command
substitutions like echo "$(curl ... | sh)" before quoted content is removed.
Preserve suppression only for genuinely non-executable lines, and add regression
tests covering both missed forms.

Handle inline shell comments.
String.starts_with?(stripped_line, "#") recognises only a full-line comment. For echo done # curl https://example.com/install.sh | sh, the match is inside the trailing shell comment, but context_safe_line?/3 returns false and CodeSafety.scan_content/2 reports a false positive. Strip only an unquoted trailing # comment before applying this rule, while retaining real commands and # inside quoted text.

Keep executable shell contexts out of the suppression path.
executable_shell_evaluation?/1 recognises only a bare sh/bash command at the start of the stripped line, plus the exact env -S and shebang forms. It returns false for /bin/sh -c 'curl ... | sh' and for echo "$(curl ... | sh)". strip_quoted_segments/1 then removes the match, so the suppression condition classifies executable download-and-run code as safe. Use shell-aware parsing or cover these execution forms before removing quoted text, and add regression tests.

Outcome
Code-safety scans now apply the existing per-line context oracle before aggregating findings. Quoted or commented pipe-to-shell guidance is ignored, while executable download-and-run commands remain blocking.
The lockfile also moves Bandit from 1.12.4 to 1.12.5, clearing EEF-CVE-2026-75484 and EEF-CVE-2026-74836.
