Periphery 3.7.4 audit of both schemes (macOS + iOS, intersected so platform-specific code is never touched), with test targets indexed and the share extension built. 277 dead declarations removed or demoted: dead forwarding wrappers (ChatViewModel+Nostr/+PrivateChat), removed- feature remnants (autocomplete command suggestions, back-swipe tuning, MediaSendError, GeohashParticipantTracker), unused Tor dormancy bindings, assign-only properties, unused parameters (renamed to _), and redundant public accessibility. 13 orphaned localization keys deleted across all 29 locales (old pre-#1392 location-notes UI, app_info warnings). Two real tests were flagged as unused because they never ran: Swift Testing methods missing @Test (NostrProtocolTests. testAckRoundTripNIP44V2_Delivered, NotificationStreamAssemblerTests. testAssemblesCompressedLargeFrame). Re-armed both; they pass. Deliberately kept, now recorded in .periphery.baseline.json: iOS-only code invisible to the CI macOS scan, C FFI signatures, keep-alive NWPathMonitor reference, InboundEventKey.eventID (dedup semantics), wifiBulk capability bit (reserved for Wi-Fi bulk work, used by BitFoundation package tests), and the String secureClear cluster (exercised by package tests). New: .periphery.yml config and an advisory Dead Code CI job (mirrors the SwiftLint precedent from #1361) that fails on findings not in the committed baseline. Verified: full macOS app suite, BitFoundation (119) and BitLogger (13) package tests green; periphery scan --strict exits clean.
