rdmbair15m5-changelog-20260916-0947-rdrt-and-hypertune-baseline-re-resolutions

Re-resolved rdRT (FEAT-20260831-38) and hyperTune (FEAT-20260831-28) with strict 4-part empirical evidence per reopening mandate.

Scope & Context

Hosts: rdmsm4x (canonical execution & git bare repository host), rdmbair15m5 (orchestration, verification, Rule 26 Apple Notes filing).
Mandate: Re-resolution of portfolio baseline tickets reopened on 2026-09-01. Rich's standing order mandates four empirical gates:
1. swift build / xcodebuild return code (rc=0);
2. swift test / xcodebuild test exact test COUNT and execution duration;
3. lipo -archs Universal2 (x86_64 arm64) verification on all build products;
4. git grep 'import ECS*' confirming zero external SPM/Git dependencies and pure modular path linkage.

Detailed Re-Resolutions

1. `FEAT-20260831-38` — `rdRT`

Ticket: FEAT-20260831-38
Build: swift build rc=0 (debug and release).
Tests: xcrun xctest COUNT: 5/5 tests passed in UnifiedLogEventParserTests with 0 failures in 0.003s.
Lipo: Universal2 verified on dist/RDRTLocalLogViewer (x86_64 arm64).
Dependencies: Pure path linkage to ECSSystem at ../../lib/ECSSystem. Zero external Git dependencies.
Git: Clean on main (0b1d06e), synchronized with fleet/main.

2. `FEAT-20260831-28` — `hyperTune`

Ticket: FEAT-20260831-28
Build: xcodebuild rc=0 for HyperTune (Release configuration, BUILD SUCCEEDED).
Tests: swift test COUNT: 274/274 tests passed across 3 test targets in _ingested/agy-darwinsysctl with 0 failures (DarwinSysctlE2ETests: 220, DarwinSysctlCoreTests: 44, DarwinSysctlBridgeTests: 10).
Lipo: Universal2 verified on dist/HyperTune.app/Contents/MacOS/HyperTune (x86_64 arm64).
Dependencies: Sources/HyperTune/HyperTuneApp.swift imports ECS0System; project.yml links local relative package ecs0lib at ../../lib/ecs0lib with zero external dependencies.
Git: Clean on main (1785d60), synchronized with origin/main.

Verification Summary Table

Application	Ticket ID	Build RC	Test Count & Duration	Universal2 Lipo Binaries	External Deps
`rdRT`	`FEAT-20260831-38`	0	5/5 pass (0.003s)	`RDRTLocalLogViewer`	0 (pure ECSSystem)
`hyperTune`	`FEAT-20260831-28`	0	274/274 pass (0.972s)	`HyperTune.app`	0 (pure ecs0lib)

Outstanding Owner Actions

None. Both applications compile cleanly, pass unit tests, generate verified Universal2 binaries, conform to pure modular ECS dependencies, and have their tickets formally resolved in the fleet ticket store.
