LAB NOTE 001 // SOURCE QUALITY
How we audited 106 command documentation links.
A source link is useful only when it reaches the right documentation. On July 29, 2026, we extracted every unique documentation URL used by the public references and authored workflows, requested each URL, investigated the failures, and reran the audit.
- Unique URLs checked
- 106
- Incorrect mappings found
- 18
- Failures after fixes
- 0
SCOPE
What the audit covered.
- Collect. Build the Git, Linux, and Docker mission bank, then deduplicate source URLs from public reference commands and authored workflow steps.
- Request. Send a live HTTP request to each of the 106 unique HTTPS URLs and record non-success responses.
- Diagnose. Compare failed mappings with the command family, manual section, and upstream project documentation.
- Prevent recurrence. Add exact mapping assertions and reject the known invalid Linux manual-page pattern in automated tests.
- Rerun. Repeat the live request pass after replacing the mappings; the final pass returned 0 failures.
ROOT CAUSE
The fallback guessed that every command had a section 1 manual page.
That assumption produced believable-looking URLs such as man1/ss.1.html, but command names do not map uniformly to that location. Some are shell builtins, some are environment syntax, some are administration tools documented in section 8, and others are maintained by separate projects.

Mappings now follow the documentation family.
| Command type | Examples | Correction |
|---|---|---|
| Shell behavior | command, umask, MY_VAR=value | Link to the relevant GNU Bash builtin or environment documentation. |
| Administration tools | ip, ss, useradd, usermod | Use the actual section 8 Linux manual page instead of a section 1 guess. |
| Independent projects | jq, ncdu, zip, unzip | Link to the maintained upstream project documentation. |
| Unknown fallback | Any command without an explicit mapping | Use the general GNU/Linux manual index instead of fabricating a command-specific URL. |

The rerun reached every audited URL, with two important caveats.
The post-fix live GET pass reached all 106 unique documentation URLs included in that audit.
An HTTP success does not prove that every explanation is complete or that a command behaves identically across platforms and versions.
Documentation moves and automated clients can be blocked. Exact mappings and build checks reduce regressions, but periodic live audits are still necessary.
