# Lardon3D — Source Comment Audit

## Status

```text
SOURCE_COMMENT_AUDIT=PASS
SOURCE_COMMENT_REMEDIATION=PASS
SOURCE_COMMENT_SCOPE=include/lardon3d/** + src/**
SOURCE_COMMENT_LANGUAGE=ENGLISH
SOURCE_CODE_BEHAVIOR_CHANGED=NO
```

The audit covered 148 C/C++ source/header files under `include/lardon3d/**` and `src/**`.

The initial static inventory reported:

```text
comment blocks                         807
raw non-English lexical candidates     33
actual French comment blocks            29
English false positives                  4
stale-contract candidates                0
raw unannotated-public declarations    324
```

## Remediation

All 29 actual French source comments were translated to English.

The four raw language-detector false positives were already English and were left unchanged.

The remediation touched comments only. A file-level lexical comparison removed comments entirely and verified that every non-comment source
byte remained identical before and after the declared replacements.

No executable UI/error string was changed in this pass. UI language is a separate explicitly scoped
implementation pass.

## Stale and misleading comments

The lexical stale-contract pass found zero candidate comments.

No scientific threshold, schema version, Task Kind, resource contract, persistence identity or FROZEN
boundary was changed by this audit.

## Public API adjacency heuristic

The first inventory reported 324 public declarations without an immediately adjacent comment.

That number is **informational only**, not 324 defects.

The repository Source Comment Contract requires comments where WHY, CONTRACT, INVARIANT, OWNERSHIP,
IDENTITY, persistence ordering, restart, cancellation, concurrency, resource accounting or a FROZEN
boundary is non-obvious. It does not require one redundant comment for every getter, thin wrapper,
paired create/load/list function or declaration already covered by a surrounding contract block.

Therefore absence of an adjacent comment alone is not a valid
`UNDER_COMMENTED`/`SEVERELY_UNDER_COMMENTED` finding.

Future audits must review semantic contract coverage rather than using declaration adjacency as a
blanket failure criterion.

## Source Comment Contract

Production source comments:

- are English;
- explain non-obvious WHY/CONTRACT/INVARIANT facts;
- preserve ownership and lifetime boundaries;
- preserve persistence/restart ordering;
- preserve concurrency/resource-accounting boundaries;
- preserve scientific identity and FROZEN constraints;
- do not paraphrase obvious code line-by-line;
- are updated when behavior changes.

## Validation

The remediation runner requires:

```text
branch = docs-audit
no unrelated worktree changes
all expected old comments match exactly once
file-level source with all comments removed remains byte-for-byte identical
no strong French-comment candidate remains
git diff --check passes
```
