<objective> Mark milestone {{version}} complete, archive to milestones/, and update ROADMAP.md and REQUIREMENTS.md.

Purpose: Create historical record of shipped version, archive milestone artifacts (roadmap + requirements), and prepare for next milestone. Output: Milestone archived (roadmap + requirements), PROJECT.md evolved, git tagged. </objective>

<execution_context> **Load these files NOW (before proceeding):**

• @~/.claude/gsd-core/workflows/complete-milestone.md (main workflow)
• @~/.claude/gsd-core/templates/milestone-archive.md (archive template)

</execution_context>

<context> **Project files:**

• `.planning/ROADMAP.md`
• `.planning/REQUIREMENTS.md`
• `.planning/STATE.md`
• `.planning/PROJECT.md`

**User input:**

• Version: {{version}} (e.g., "1.0", "1.1", "2.0")

</context>

<process>

**Follow complete-milestone.md workflow:**

0. **Check for audit:**

• Look for `.planning/v{{version}}-MILESTONE-AUDIT.md`
• If missing or stale: recommend `/gsd-audit-milestone` first
• If audit status is `gaps_found`: recommend closing the gaps inline

(the audit output already enumerates them — insert closure phases via `/gsd-phase --insert <N>` plus the standard discuss/plan/execute chain) before proceeding.

• If audit status is `passed`: proceed to step 1

   ## Pre-flight Check

   {If no v{{version}}-MILESTONE-AUDIT.md:}
   ⚠ No milestone audit found. Run `/gsd-audit-milestone` first to verify
   requirements coverage, cross-phase integration, and E2E flows.

   {If audit has gaps:}
   ⚠ Milestone audit found gaps. The audit output already enumerates the
   unsatisfied requirements, cross-phase issues, and broken flows — insert
   a closure phase per gap with `/gsd-phase --insert <N>` and run the
   standard `/gsd-discuss-phase` → `/gsd-plan-phase` → `/gsd-execute-phase`
   chain. Or proceed anyway to accept the gaps as tech debt.

   {If audit passed:}
   ✓ Milestone audit passed. Proceeding with completion.

1. **Verify readiness:**

• Check all phases in milestone have completed plans (SUMMARY.md exists)
• Present milestone scope and stats
• Wait for confirmation

2. **Gather stats:**

• Count phases, plans, tasks
• Calculate git range, file changes, LOC
• Extract timeline from git log
• Present summary, confirm

3. **Extract accomplishments:**

• Read all phase SUMMARY.md files in milestone range
• Extract 4-6 key accomplishments
• Present for approval

4. **Archive milestone:**

• Create `.planning/milestones/v{{version}}-ROADMAP.md`
• Extract full phase details from ROADMAP.md
• Fill milestone-archive.md template
• Update ROADMAP.md to one-line summary with link

5. **Archive requirements:**

• Create `.planning/milestones/v{{version}}-REQUIREMENTS.md`
• Mark all v1 requirements as complete (checkboxes checked)
• Note requirement outcomes (validated, adjusted, dropped)
• Delete `.planning/REQUIREMENTS.md` (fresh one created for next milestone)

6. **Update PROJECT.md:**

• Add "Current State" section with shipped version
• Add "Next Milestone Goals" section
• Archive previous content in `<details>` (if v1.1+)

7. **Commit and tag:**

• Stage: MILESTONES.md, PROJECT.md, ROADMAP.md, STATE.md, archive files
• Commit: `chore: archive v{{version}} milestone`
• Tag: `git tag -a v{{version}} -m "[milestone summary]"`
• Ask about pushing tag

8. **Offer next steps:**

• `/gsd-new-milestone` — start next milestone (questioning → research → requirements → roadmap)

</process>

<success_criteria>

• Milestone archived to `.planning/milestones/v{{version}}-ROADMAP.md`
• Requirements archived to `.planning/milestones/v{{version}}-REQUIREMENTS.md`
• `.planning/REQUIREMENTS.md` deleted (fresh for next milestone)
• ROADMAP.md collapsed to one-line entry
• PROJECT.md updated with current state
• Git tag v{{version}} created (if `git.create_tag` enabled)
• Commit successful
• User knows next steps (including need for fresh requirements)

</success_criteria>

<critical_rules>

• **Load workflow first:** Read complete-milestone.md before executing
• **Verify completion:** All phases must have SUMMARY.md files
• **User confirmation:** Wait for approval at verification gates
• **Archive before deleting:** Always create archive files before updating/deleting originals
• **One-line summary:** Collapsed milestone in ROADMAP.md should be single line with link
• **Context efficiency:** Archive keeps ROADMAP.md and REQUIREMENTS.md constant size per milestone
• **Fresh requirements:** Next milestone starts with `/gsd-new-milestone` which includes requirements definition
