Step 4 MVP Triage — Completion Walkthrough

Change Made

One file modified:

• README.md — Added a 6-line blockquote copy-notice header at the top of the file, before the existing upstream README content. The header:
  • Identifies this as a locally corrected copy
  • Points to ../PROVENANCE.md for correction details
  • Warns that re-copying from upstream without reapplying corrections will reintroduce known defects
  • Does not modify any of the original upstream README body

Validation

Check	Result
git diff --check	✅ Clean (exit 0)
python devlog_editor.py --validate	✅ "devlog is valid"

Triage Summary

Finding	Classification	Action Taken
F-1 INVALID_ARGUMENTS	Not actually a defect — §9.5 mandates INVALID_VALUE	None needed
F-2 Descriptor validation	Safe to defer — permissive but conformant	Deferred to restore milestone
F-3 README framing	Should fix now — evidence-integrity risk	Applied
F-4 Browser evidence	Informational only	None needed
F-5 stateRevision session persistence	Informational only — already in Authoring Guide	None needed

Next Steps

• No commit or push was performed (per AGENTS.md rules)
• The milestone verdict can now be changed to: STEP 4 MVP COMPLETE — READY FOR NEXT STEP 4 PHASE
• New application files remain untracked until the owner requests staging/commit
