It is preserved as +evidence of the project's clean-room posture against GNU shadow-utils +(GPL-2.0+). + +## Why an audit at all + +The project's clean-room policy (`CONTRIBUTING.md`) forbids reading +shadow-maint/shadow source. +That guarantees no commit ever derives from upstream — but it cannot, by +itself, prove the absence of accidental similarity in user-facing strings +(error messages, clap flag-help, `--help` text). This audit is the +evidence side of the policy: independent verification that no string in +the tree is a verbatim copy of upstream wording. + +## Protocol + +The audit was performed by an LLM with the `shadow-maint/shadow` source +code in its training corpus, run from a clean-room driver outside the +repository's working tree. The protocol guarantees no upstream content +crosses back into the repository: + +1. **Output schema** — the LLM's response was constrained to a strict + JSON Schema admitting only `{file, line, verdict, confidence, category}` + per finding plus a length-capped `notes` field. The schema literally + has no field where a GNU-shadow string could land. +2. **Verdicts** — five labels: `verbatim`, `near-paraphrase`, `idiomatic`, + `independent`, `abstain`. Confidence in `{high, medium, low}`. +3. **Sandbox** — the tool ran with `--ephemeral --sandbox workspace-write` + and was instructed not to clone, fetch, or webfetch shadow-maint/shadow + or any GNU shadow-utils mirror. +4. **Output channel** — only the schema-validated JSON message was + captured. The progress log was scanned for `shadow-maint`, + `github.com/shadow`, `apt-get source`, `git clone`, `wget`, `curl` — no + command invocations targeted upstream. +5. **Provenance** — the only "shadow" URLs that appeared in the log were + the prompt's own warning text and our own `https://github.com/uutils/shadow-rs` + constant. + +The model's task was to classify every user-facing string literal in the +listed files (clap `.help/.about/.long_about/.override_usage/.after_help`, +`uucore::show_error!`, `eprintln!/println!`, `writeln!(io::stderr/stdout)`, +`panic!/unreachable!`) without ever quoting upstream. If unable to +classify without quoting, it was instructed to emit `abstain`. + +## Results + +| Verdict | Count | Share | +|-------------------|------:|------:| +| **verbatim** | **0** | **0.0%** | +| near-paraphrase | 134 | 27.6% | +| idiomatic | 218 | 44.9% | +| independent | 62 | 12.8% | +| abstain | 72 | 14.8% | +| **total examined** | 486 | | + +**Headline: 0 verbatim matches.** + +### Triage of the 134 near-paraphrases + +- **16 high-confidence** all fall under the behavioral-compatibility + carve-out — output strings that scripts grep for and where the project + explicitly commits to drop-in compat with GNU shadow (`CONTRIBUTING.md` + Design Goals: *"Drop-in replacement: same flags, same exit codes, same + output format as GNU shadow-utils"*). + Distribution: + - `chage -l` aging-info column headings — `src/uu/chage/src/chage.rs` + lines 442, 466–480 (the function comment itself reads + "Print the aging information in the GNU `chage -l` format"). + - `pwck` diagnostic output — `src/uu/pwck/src/pwck.rs` lines 385, + 478, 504, 510, 519. + - `grpck` diagnostic output — `src/uu/grpck/src/grpck.rs` lines 209, + 251, 261. + + Under the merger doctrine, copyright does not attach to expression + dictated by external function (here: drop-in compat).

They live mostly in `src/shadow-core/src/{validate,crypt,error}.rs` +and the `show_error!` paths of the user tools.
