Wave C Closeout

Wave Closeout

  • Wave: Wave C
  • Status: completed (hard-close)
  • Date: 2026-03-09
  • Owner: Codex
  • Objective: establish a repeatable packaging and distribution path for desktop and extension artifacts.

Scope Completed

  • added and validated a release-readiness gate script for packaging prerequisites
  • added and executed a repeatable Wave C evidence collector script
  • validated unsigned AppImage packaging and linux-unpacked artifact startup
  • validated VS Code extension install/build/pack-dry-run path
  • added explicit Electron env isolation wrapper to prevent global ELECTRON_RUN_AS_NODE contamination
  • updated runbooks with the scoped legacy-command pattern

Files Changed

Breaking Changes Introduced

  • none to runtime behavior; changes are additive and control-oriented

Compatibility Shims Added

  • scripts/with_clean_electron_env.sh to isolate Electron runs from shell-global env contamination

Compatibility Shims Removed

  • none

Verification Performed

  • maestro/scripts/release_readiness_check.sh
  • maestro/scripts/release_collect_evidence.sh
  • Evidence artifact set: reports/wave-c_20260309T154457Z/*

Residual Risks

  • update/publish endpoint ownership remains inherited and is explicitly deferred to Wave D
  • host-level snap libgiolibproxy warning remains visible in smoke logs
  • dependency vulnerability remediation remains out of scope for this hard-close due to frozen-lane controls

Rollback Point

  • pending commit for Wave C hard-close

Entry Criteria For Next Wave

  • Wave C evidence and closeout published
  • modernization matrix marks Wave C complete
  • Wave D begins with external ownership inventory and migration constraints
