Verified dead-code + duplication cleanup over the WireGuard feature surface
(found via an audit workflow, every item adversarially re-verified by grep):
Dead code removed:
- lang keys not_configured_title / not_configured_body (both locales) — orphaned
when the unconfigured empty state became the in-page setup form (setup_title /
setup_intro). 0 references anywhere. de/en parity kept (83/83).
- WgTraffic::series() 'buckets' return key — written, never read by blade/route/test.
- blade $fmtB byte-formatter — byte-identical duplicate of the top-level $fmtBytes
already in scope; collapsed onto $fmtBytes.
DRY / readability (behavior-preserving):
- Index: PEER_NAME_RE constant (was the same regex literal at 5 sites), portInRange()
+ clampWindow() helpers (window default now self::WINDOWS[0]), openConfirm() helper
(5 confirm-modal openers shared one dispatch), onFlag() helper (2 apply handlers).
- WgBridge: validPort() helper (port check was duplicated verbatim).
- clusev-wg.sh: _write_server_conf() shared by both setup paths (the byte-identical
server bring-up was copy-pasted); single CIDR_RE constant for the 3 subnet checks;
fixed a stale header comment that still claimed SSH is "NEVER matched" (the v0.9.40
ssh-lock can match 22); documented the defence-in-depth re-validation in _set_*.
- WgStatus: documented server.pubkey is part of the /wg-status.json contract (kept).
No DB/migration changes (peer_name write-only column left intact — needs a
coordinated migration). 348 tests pass, shellcheck clean, Pint clean, R12 verified
in both the configured + unconfigured states (200, no console errors, no leaked
keys, traffic formatter renders 1.5 MB / 200 KB correctly).
