rdmsm4x-changelog-20260825-1457-rtty-build42-fleet-deploy

RTTy 0.3.820 build 42 deployed to all six fleet Macs and 234 legacy app bundles removed, each hashed into a per-host manifest before deletion.

Scope

All six hosts: rdmsm4x, rdmbair13m5, rdmbair15m5, rdmpw3265m, rdmpw3275m, jdmbair13m5 (reached via .local; .ts address dropped connections).

/Applications/RTTy.app on every host replaced with the 0.3.820 build 42 universal candidate (arm64 + x86_64, min macOS 26.7, commit 001cbd8, branch codex/rtty-build42-20260824, team ZU2882L4HT hardened runtime). Deployed with script/deploy_preview_remote.sh: archive sha256 28ccfd40…b9b19f, executable sha256 71628a6b…c6d1cd, checksum + codesign + universal-arch verified on every host before install; app relaunched in each console session; preferences migrated/preserved (already-present on five hosts, fresh defaults on jdmbair13m5).
Rollback: each host keeps /Applications/RTTy.app.backup-build40-<stamp> from today. Restore = quit RTTy, sudo mv the backup back, relaunch.
Legacy cleanup (Rich's instruction): 234 bundles removed fleet-wide — pre-rename LatencyBar.app/Logstreamed.app backups and rollbacks, stale RTTy.app/LogTTY.app backups/rollbacks/failed candidates, stray copies (RTTy copy.app, ~/Applications side-loads). Kept everywhere: current /Applications/RTTy.app + LogTTY.app and today's build-40 backups. Every removal recorded first (path, CFBundleVersion, executable sha256) in Project/build42/fleet-cleanup-manifests/legacy-cleanup-<host>.txt, committed at 0beb8f4 on codex/rtty-build42-20260824 (pushed to github.com/richhdoty/RTTy).
Mystery closed: BUILD-42-PLAN WS6's unknown 822.42 artifact was a stray ~/Applications/RTTy.app on rdmbair15m5; hashed in that manifest, removed.

Build: ./script/build_and_run.sh --verify (universal + signature verify)
Package: ditto -c -k --keepParent dist/RTTy.app /tmp/rtty-0.3.820-b42.zip
Per host: bash /tmp/deploy_preview_remote.sh <zip> <archive-sha> <exe-sha> then bash /tmp/cleanup_legacy_builds.sh (script preserved in the session scratchpad and reproduced by the manifests' header).

Every host reports CFBundleVersion 42 from /Applications/RTTy.app and a running process at that path post-install.
Build 42 content: build-39 feature restoration, macOS 26.7/27 retarget, latency-chart continuity + cadence fixes, Keychain test isolation, privacy boundary tests, continuous-then-one-shot nettop flow monitor (per-app flows band, Direct channel), 699/702 test cases green, qa gates 1–4+8 passed.

Accessibility (TCC) grant on rdmsm4x for qa gates 5–7 — cannot be scripted.
