rdmsm4x-changelog-20260903-2028-rtty-xcode266-removed-session-state

Session state recorded after RTTy Build 48 acceptance; Xcode 26.6 was moved to Trash by Rich mid-diagnosis, which blocks future Standard/mobile archive gates until DEC-20260903-07 is decided.

Scope

• Host: rdmsm4x only. No fleet host touched. No Xcode bundle moved by the agent.

What changed (agent)

• ~/dev/_handoff/rtty-native-nettop-20260903/universe/apps/RTTy/SESSION-STATE.md — new top section (six-question handoff), committed on branch codex/rtty-native-nettop-20260903 and pushed to origin (branch only; main untouched).
• ~/dev/PROJECTS.md — RTTy row status cell notes the archive blocker and ticket IDs.
• Tickets: ISSUE-20260903-35 (incident, needs-decision, blocked-by DEC-20260903-07); DEC-20260903-07 (three options: restore from Trash / re-pin to Xcode 27 / clean reinstall 26.6).

What changed (Rich, observed)

• 19:51 EDT: /Applications/Xcode.app (Xcode 26.6, 17F113) plus its caches/prefs moved to ~/.Trash.

Verification

• Trash copy complete: du -sh -A 8.3G, 120215 files, all platforms/SDKs/toolchain present, ProductBuildVersion 17F113.
• Pin evidence: grep -rn '/Applications/Xcode.app\|17F113' script Tests in the RTTy writer tree (ISSUE-20260903-35 lists the files).
• Today's Xcode hang reports (Xcode_2026-09-03-091736, -174321) are Xcode 27 beta 6 (1166 s, 28730 s).

Undo

• Restore toolchain: mv ~/.Trash/Xcode.app /Applications/Xcode.app (Rich's call, DEC-20260903-07).
• Revert state note: git revert <commit> on the branch; PROJECTS.md row is a one-line edit.

Outstanding owner actions

• Decide DEC-20260903-07. Do not empty the Trash first.
• Register rdawU3 and rdavp1 (DEC-20260903-03 decoupled physical iOS validation stands).
