rdmbair15m5-changelog-20260910-1943-subnet-calculator-app

Completed end-to-end development, strict concurrency verification, adversarial hardening, and independent victory audit of the modern Subnet Calculator for macOS, iOS, and iPadOS.

Scope

• Host: rdmbair15m5 (local work environment)
• Target: /Users/richh/teamwork_projects/subnet_calculator
• Platforms: macOS 15+, iOS 18+, iPadOS 18+ (first-class Stage Manager)

What Was Done

1. Multiplatform IPv4 & IPv6 Subnet Engine (SubnetCore):
   • Implemented full addressing properties for IPv4 /0-/32 and IPv6 /0-/128.
   • Verified edge cases: RFC 3021 /31 point-to-point (2 usable hosts), /32 single host routes, RFC 6164 /127 inter-router links, /128 single host routes.
   • Implemented 256-bit safe scalar capacity arithmetic (BigIntUInt) guaranteeing zero overflow up to $2^{128}$ hosts.
   • Structured visual bitwise representations and multi-format hex layout bundles.
   • Hierarchy navigation: parent supernet, preceding/succeeding siblings, split child subnets.
2. Intelligent Paste Ingestion & Multi-Format Parser (SubnetParser):
   • Formats supported: CIDR, IP with subnet mask (space/slash/tab), IP with Cisco wildcard, hyphenated IP ranges, and unstructured configs (Cisco IOS/ASA, Junos, Arista EOS, Linux iproute2, Windows netsh).
   • $O(1)$ bitwise mask contiguity verification ((~maskRaw &+ 1) & ~maskRaw) == 0.
   • Greedy minimal power-of-two CIDR range decomposition with ceiling overflow protections.
   • Non-blocking syntax diagnostics matching all E2E error codes.
3. Offline IANA Categorization & Asynchronous RDAP Engine (SubnetLookup):
   • Zero-latency longest-prefix match (LPM) classifier over 25 IPv4 + 21 IPv6 IANA special-purpose registries.
   • Pre-flight filter eliminating outbound queries for private/documentation addresses.
   • RFC 9224 multi-RIR bootstrap routing (ARIN, RIPE, APNIC, LACNIC, AFRINIC) with actor isolation, HTTP redirect loop guards, and jittered exponential backoff.
   • Dual-tier cache: in-memory LRU + atomic disk persistence with SHA-256 keys and offline fallback.
4. Apple-Native SwiftUI UI with Liquid Glass (SubnetUI & SubnetIntents):
   • Adaptive multiplatform layout: 3-column split view with collapsible inspector on macOS 15+ and iPadOS 18+ (Stage Manager), drill-down navigation on iOS 18+.
   • ecs0lib Liquid Glass design tokens with availability-gated translucent materials and system fallbacks.
   • Exhaustive metric cards, visual subnet tree, interactive bitwise demarcation, and 1-click clipboard copy.
   • Apple Intelligence surface (AppEntity, CalculateSubnetIntent, AppShortcutsProvider).
   • Universal2 (x86_64 arm64) release packaging signed with Developer ID under Team ID ZU2882L4HT and Bundle ID com.eastcoastscience.SubnetCalculator, with Metadata.appintents and Apple Privacy Manifest (PrivacyInfo.xcprivacy).
5. Quality & Verification:
   • Swift 6 strict concurrency (-strict-concurrency=complete): 0 warnings, 0 errors.
   • SwiftPM unit & adversarial tests: 325 / 325 passed (100%).
   • Independent opaque-box E2E tests: 379 / 379 passed (100%).
   • Independent Victory Audit: Unconditional VICTORY CONFIRMED by post-victory auditor (e04db8dd-67be-4ebb-b0b7-ace0eb8065d5).

Commands Run

• swift build -Xswiftc -strict-concurrency=complete
• swift test
• python3 tests/e2e/test_runner.py
• ~/bin/fleet_sign_unlock && ./scripts/build_macos_release.sh
• lipo -archs dist/SubnetCalculator.app/Contents/MacOS/SubnetCalculator

Verification Evidence

• SwiftPM test suite: 325/325 passing across SubnetCoreTests, SubnetParserTests, SubnetLookupTests, SubnetUITests, SubnetIntentsTests.
• E2E test suite: 379/379 passing across Tiers 1-4.
• Universal2 release artifact: dist/SubnetCalculator.app (x86_64 arm64).
• App Intents metadata: dist/SubnetCalculator.app/Contents/Resources/Metadata.appintents/extract.actionsdata (40 intents).
• Victory Audit: VICTORY CONFIRMED recorded in .agents/victory_auditor/audit_report.md.

Outstanding Owner Actions

• Ready for App Store submission or TestFlight distribution under Team ID ZU2882L4HT.

Post-Reset Auto-Resume & Custom Icon Update (2026-09-10 21:14 EDT)

• Quota Reset Resume: Executed fleet/agy-session-watch/agy-resume-at-reset.sh --arm. Blocked session on ttys000 (8c745619) successfully nudged and resumed (0 blocked, 2 working).
• Custom App Icon: Converted /Users/richh/Desktop/macOS-iOS_subnet-calculator.png via sips into 10 iconset resolutions and compiled to Config/AppIcon.icns using iconutil.
• Packaging & Desktop Launch: Bundled AppIcon.icns into dist/SubnetCalculator.app/Contents/Resources/AppIcon.icns, re-verified universal2 binary (x86_64 arm64), re-signed with Developer ID Richard Doty (S65Q255HA8), deployed to /Users/richh/Desktop/SubnetCalculator.app, and launched on the desktop (PID 41737).
