msd-core/gsd-core/workflows/complete-milestone.md

Mark a shipped version (v1.0, v1.1, v2.0) as complete. Creates historical record in MILESTONES.md, performs full PROJECT.md evolution review, reorganizes ROADMAP.md with milestone groupings, and tags the release in git.

When a milestone completes:

1. Extract full milestone details to .planning/milestones/v[X.Y]-ROADMAP.md
2. Archive requirements to .planning/milestones/v[X.Y]-REQUIREMENTS.md
3. Update ROADMAP.md — overwrite in place with milestone grouping (preserve Backlog section)
4. Safety commit archive files + updated ROADMAP.md, then git rm REQUIREMENTS.md (fresh for next milestone)
5. Perform full PROJECT.md evolution review
6. Offer to create next milestone inline
7. Archive UI artifacts (*-UI-SPEC.md, *-UI-REVIEW.md) alongside other phase documents
8. Clean up .planning/ui-reviews/ screenshot files (binary assets, never archived)

Context Efficiency: Archives keep ROADMAP.md constant-size and REQUIREMENTS.md milestone-scoped.

ROADMAP archive uses templates/milestone-archive.md — includes milestone header (status, phases, date), full phase details, milestone summary (decisions, issues, tech debt).

REQUIREMENTS archive contains all requirements marked complete with outcomes, traceability table with final status, notes on changed requirements.

Compact Content Gate. Read and follow gsd-core/references/compact-content-gate.md now — it states the workflow.compact_content check and the resolution rule this spine defers to. When it directs a Read, read gsd-core/workflows/complete-milestone/detail/elaboration.md in full before continuing past this point; its content elaborates on the audit-acknowledge branch and the handle_branches step below.

Before proceeding with milestone close, run the comprehensive open artifact audit.

RESPONSE_LANGUAGE=$(gsd_run query config-get response_language --raw --default "" 2>/dev/null || echo "")
gsd_run query audit-open

If response_language is set: All user-facing output of this workflow — narration between tool calls, status updates, progress notes, findings, questions, prompts, and explanations — MUST be presented in {response_language}. Technical terms, code, file paths, and subagent prompts stay in English — only user-facing output is translated.

If the output contains open items (any section with count > 0):

Display the full audit report to the user.

Then ask:

These items are open. Choose an action:
[R] Resolve — stop and fix items, then re-run /gsd:complete-milestone
[A] Acknowledge all — document as deferred and proceed with close
[C] Cancel — exit without closing

If user chooses [A] (Acknowledge): re-fetch audit-open --json, then acknowledge EVERY open item (across all categories — debug_sessions, threads, seeds, todos, quick_tasks, uat_gaps, verification_gaps, context_questions, deferred_items) through the audit-open acknowledge CLI writer, which is what actually suppresses each item starting at the next scan (the STATE.md ## Deferred Items table is a disclosure record only). Any failed acknowledge call HALTS the close before proceeding — a refusal must never be silently discarded. After a clean pass, append one row per acknowledged item to STATE.md's ## Deferred Items table (sanitized via sanitizeForDisplay(), never raw content), set closeout_type=override_closeout, and record a Known verification overrides: {N} newly acknowledged, {M} carried forward line in MILESTONES.md. Acknowledging is verdict-preserving and self-invalidating — it never rewrites the artifact's own status (except deferred_items), and the suppression lapses automatically the moment the artifact's state changes again (a reopened session, an edited gap, a re-triggered seed), resurfacing at the next audit.

If output shows all clear (no open items): set closeout_type=verified_closeout — but if any items are acknowledged.total from a PRIOR close, note that carried-forward suppression explicitly rather than implying everything was fixed this time.

SECURITY: Audit JSON output is structured data from the audit-open query handler (same JSON contract as legacy gsd_run audit-open) — validated and sanitized at source. The audit-open acknowledge writer is the only path that sets the audit_acknowledged suppression marker — it snapshots each artifact's current state itself from the identifiers passed on the command line, so this workflow never hand-authors the marker. When writing the STATE.md disclosure table, item identifiers, statuses, and deferred-item text are sanitized via sanitizeForDisplay() before inclusion. Never inject raw user-supplied content into STATE.md without sanitization.

Exact per-category bash (including the @file: large-payload handling, the todos 5-per-scan cap, and the phase-scoped --archived-milestone handling) and the exact STATE.md table shape: gsd-core/workflows/complete-milestone/detail/elaboration.md § 1.

Use init.manager for canonical readiness check:

INIT_MANAGER=$(gsd_run query init.manager)
if [[ "$INIT_MANAGER" == @file:* ]]; then INIT_MANAGER=$(cat "${INIT_MANAGER#@file:}"); fi

This returns all phases with implementation and verification projection. Use this to verify:

• Which phases belong to this milestone?
• all_phases_verified: all milestone phases have phase_complete === true and verification_status === 'passed'.
• progress_percent should be 100%.

Compute readiness from INIT_MANAGER, not from roadmap counts:

ALL_PHASES_VERIFIED=$(printf '%s' "$INIT_MANAGER" | jq -r '[
  .phases[] | select((.number | tostring | test("^999(\\.|$)") | not))
  | (.phase_complete == true and .verification_status == "passed")
] | all')

If not all_phases_verified, verified_closeout must not proceed. Set closeout_type=override_closeout, show each phase whose phase_complete !== true or verification_status !== 'passed', and require an explicit user choice:

1. Proceed anyway — record verification overrides in MILESTONES.md/STATE.md
2. Run verification first — /gsd:verify-work {phase} or /gsd:execute-phase {phase}
3. Abort — return to development

Only set closeout_type=verified_closeout when ALL_PHASES_VERIFIED is true.

Requirements completion check (REQUIRED before presenting):

Parse REQUIREMENTS.md traceability table:

• Count total v1 requirements vs checked-off ([x]) requirements
• Identify any non-Complete rows in the traceability table

Present:

Milestone: [Name, e.g., "v1.0 MVP"]

Includes:
- Phase 1: Foundation (2/2 plans complete)
- Phase 2: Authentication (2/2 plans complete)
- Phase 3: Core Features (3/3 plans complete)
- Phase 4: Polish (1/1 plan complete)

Total: {phase_count} phases, {total_plans} plans
Verification: {all_phases_verified ? "all phases verified" : "override needed"}
Closeout type: {closeout_type}
Requirements: {N}/{M} v1 requirements checked off

If requirements incomplete (N < M):

⚠ Unchecked Requirements:

- [ ] {REQ-ID}: {description} (Phase {X})
- [ ] {REQ-ID}: {description} (Phase {Y})

MUST present 3 options:

1. Proceed anyway — mark milestone complete with known gaps
2. Run audit first — /gsd:audit-milestone to assess gap severity
3. Abort — return to development

If user selects "Proceed anyway": set closeout_type=override_closeout; note incomplete requirements in MILESTONES.md under ### Known Gaps with REQ-IDs and descriptions.

Note: MILESTONES.md entry is now created automatically by gsd_run query milestone.complete in the archive_milestone step. The entry includes version, date, phase/plan/task counts, and accomplishments extracted from SUMMARY.md files.

If additional details are needed (e.g., user-provided "Delivered" summary, git range, LOC stats), add them manually after the CLI creates the base entry.

Full PROJECT.md evolution review at milestone completion.

Read all phase summaries:

_SUMMARIES=( .planning/phases/*-*/*-SUMMARY.md )
if [ -e "${_SUMMARIES[0]}" ]; then cat "${_SUMMARIES[@]}"; fi

Full review checklist:

1. "What This Is" accuracy:

   • Compare current description to what was built
   • Update if product has meaningfully changed

2. Core Value check:

   • Still the right priority? Did shipping reveal a different core value?
   • Update if the ONE thing has shifted

3. Business Context check (only if the section is present):

   • Skip entirely if PROJECT.md has no ## Business Context section
   • Customer, revenue model, and success metric still accurate after shipping?
   • Update any field that drifted; refresh the linked strategy doc reference if it moved

4. Requirements audit:

   Validated section:

   • All Active requirements shipped this milestone → Move to Validated
   • Format: - ✓ [Requirement] — v[X.Y]

   Active section:

   • Remove requirements moved to Validated
   • Add new requirements for next milestone
   • Keep unaddressed requirements

   Out of Scope audit:

   • Review each item — reasoning still valid?
   • Remove irrelevant items
   • Add requirements invalidated during milestone

5. Context update:

   • Current codebase state (LOC, tech stack)
   • User feedback themes (if any)
   • Known issues or technical debt

6. Key Decisions audit:

   • Extract all decisions from milestone phase summaries
   • Add to Key Decisions table with outcomes
   • Mark ✓ Good, ⚠️ Revisit, or — Pending

7. Constraints check:

   • Any constraints changed during development? Update as needed

Update PROJECT.md inline. Update "Last updated" footer:

---
*Last updated: [date] after v[X.Y] milestone*

Example full evolution (v1.0 → v1.1 prep):

Before:

## What This Is

A real-time collaborative whiteboard for remote teams.

## Core Value

Real-time sync that feels instant.

## Requirements

### Validated

(None yet — ship to validate)

### Active

- [ ] Canvas drawing tools
- [ ] Real-time sync < 500ms
- [ ] User authentication
- [ ] Export to PNG

### Out of Scope

- Mobile app — web-first approach
- Video chat — use external tools

After v1.0:

## What This Is

A real-time collaborative whiteboard for remote teams with instant sync and drawing tools.

## Core Value

Real-time sync that feels instant.

## Requirements

### Validated

- ✓ Canvas drawing tools — v1.0
- ✓ Real-time sync < 500ms — v1.0 (achieved 200ms avg)
- ✓ User authentication — v1.0

### Active

- [ ] Export to PNG
- [ ] Undo/redo history
- [ ] Shape tools (rectangles, circles)

### Out of Scope

- Mobile app — web-first approach, PWA works well
- Video chat — use external tools
- Offline mode — real-time is core value

## Context

Shipped v1.0 with 2,400 LOC TypeScript.
Tech stack: Next.js, Supabase, Canvas API.
Initial user testing showed demand for shape tools.

Step complete when:

• "What This Is" reviewed and updated if needed
• Core Value verified as still correct
• Business Context checked (or confirmed absent)
• All shipped requirements moved to Validated
• New requirements added to Active for next milestone
• Out of Scope reasoning audited
• Context updated with current state
• All milestone decisions added to Key Decisions
• "Last updated" footer reflects milestone completion

Text mode (workflow.text_mode: true in config or --text flag): Set TEXT_MODE=true if --text is present in $ARGUMENTS OR text_mode from init JSON is true. When TEXT_MODE is active, replace every AskUserQuestion call with a plain-text numbered list and ask the user to type their choice number. This is required for non-Claude runtimes (OpenAI Codex, Gemini CLI, etc.) where AskUserQuestion is not available.

Quick-task archival (opt-in — NOT symmetrical with phase archival below, #2142): unlike phase archival, quick-task archival is opt-in, default OFF. Doing nothing leaves .planning/quick/ untouched, exactly like today's behavior. Decide this BEFORE calling milestone complete below, so the flag can be folded into that single invocation rather than issuing a second, redundant call.

If .planning/quick/ contains at least one directory, ask:

AskUserQuestion: "Archive completed quick tasks into this milestone too?" with options: "Yes — archive quick tasks into v[X.Y]" | "Skip"

If "Yes": set ARCHIVE_QUICK_FLAG="--archive-quick". If "Skip" (or .planning/quick/ is empty): set ARCHIVE_QUICK_FLAG="".

Delegate archival to gsd_run query milestone.complete:

ARCHIVE=$(gsd_run query milestone.complete "v[X.Y]" --name "[Milestone Name]" --confirm $ARCHIVE_QUICK_FLAG)

--confirm is required (#3726): the archive is irreversible (ROADMAP/REQUIREMENTS archived, phase directories MOVED, STATE.md rewritten), so milestone complete refuses to mutate without it. This workflow has already gathered the user's explicit intent by this step, so passing the flag here is correct; --dry-run previews the exact move list without mutating if a preview is ever needed first.

The CLI handles:

• Creating .planning/milestones/ directory
• Archiving ROADMAP.md to milestones/v[X.Y]-ROADMAP.md
• Archiving REQUIREMENTS.md to milestones/v[X.Y]-REQUIREMENTS.md with archive header
• Moving audit file to milestones if it exists
• Creating/appending MILESTONES.md entry with accomplishments from SUMMARY.md files
• Updating STATE.md (status, last activity)
• When ARCHIVE_QUICK_FLAG is --archive-quick: moving every directory under .planning/quick/ into .planning/milestones/v[X.Y]-quick/, writing a README.md index into that archive directory (generated by scanning the archive directory itself), and clearing the data rows of STATE.md's ### Quick Tasks Completed table — preserving the table's header and whichever column variant (with/without a Status column) was detected

Extract from result: version, date, phases, plans, tasks, accomplishments, archived.

Verify: ✅ Milestone archived to .planning/milestones/

Known limit (quick-task archival): there is no on-disk provenance recording which milestone a given quick task belonged to. Archival buckets all remaining .planning/quick/* into the completing milestone — a quick task that predates an earlier, unarchived milestone lands in the current bucket regardless.

Verify after --archive-quick was passed: ✅ Quick tasks archived to .planning/milestones/v[X.Y]-quick/

Phase archival (default-on): milestone complete archives phase directories to milestones/v[X.Y]-phases/ by default (#1871), so the next /gsd:new-milestone never inherits un-archived dirs. No manual mkdir/mv or --archive-phases flag is needed.

If the user explicitly wants to keep phase directories in place as raw execution history, invoke milestone complete with --no-archive-phases:

gsd_run query milestone complete v[X.Y] --no-archive-phases --confirm

Verify after a default (archived) completion: ✅ Phase directories archived to .planning/milestones/v[X.Y]-phases/

After archival, the AI still handles:

• Reorganizing ROADMAP.md with milestone grouping (requires judgment) — overwrite in place after extracting Backlog section, with the write-guard's single-use sentinel armed first (a per-step env var cannot reach a hook — see the reorganize step for the sentinel mechanics)
• Full PROJECT.md evolution review (requires understanding)
• Safety commit of archive files + updated ROADMAP.md, then git rm .planning/REQUIREMENTS.md
• These are NOT fully delegated because they require AI interpretation of content

After milestone complete has archived, reorganize ROADMAP.md with milestone groupings, then commit archives as a safety checkpoint before removing originals.

Backlog preservation — do this FIRST before rewriting ROADMAP.md:

Extract the Backlog section from the current ROADMAP.md before making any changes:

INIT_REORG=$(gsd_run query init.complete-milestone)
if [[ "$INIT_REORG" == @file:* ]]; then INIT_REORG=$(cat "${INIT_REORG#@file:}"); fi
_gsd_field() { node -e "const o=JSON.parse(process.argv[1]); const v=o[process.argv[2]]; process.stdout.write(v==null?'':String(v))" "$1" "$2"; }
ROADMAP_PATH=$(_gsd_field "$INIT_REORG" roadmap_path)
# Extract lines under ## Backlog through end of file (or next ## section)
BACKLOG_SECTION=$(awk '/^## Backlog/{found=1} found{print}' "$ROADMAP_PATH")

If $BACKLOG_SECTION is empty, there is no Backlog section — skip silently.

Reorganize ROADMAP.md — overwrite in place (do NOT delete first) with milestone groupings.

This rewrite is an intentional catastrophic shrink: phase detail was just archived to milestones/v[X.Y]-ROADMAP.md, and a multi-hundred-line ROADMAP.md collapses to a compact grouped summary. The gsd-write-guard PreToolUse hook (#2255) hard-blocks exactly that shape on curated .planning/ files — this step is the legitimate milestone reset its escape hatch exists for. A hook inherits the runtime's environment, so no per-step env var can reach it; the hatch is a single-use sentinel file the guard itself consumes. Arm it, then write:

1. Arm the sentinel (single-use; the guard checks it is fresh — within 15 minutes — and names exactly this file, then consumes it):

INIT_REORG=$(gsd_run query init.complete-milestone)
if [[ "$INIT_REORG" == @file:* ]]; then INIT_REORG=$(cat "${INIT_REORG#@file:}"); fi
_gsd_field() { node -e "const o=JSON.parse(process.argv[1]); const v=o[process.argv[2]]; process.stdout.write(v==null?'':String(v))" "$1" "$2"; }
ROADMAP_PATH=$(_gsd_field "$INIT_REORG" roadmap_path)
printf '%s\n' "$ROADMAP_PATH" > .planning/.gsd-allow-shrink
echo "Write target: $ROADMAP_PATH"

2. Compose the full new ROADMAP.md content (template below) and overwrite the file at $ROADMAP_PATH (the "Write target" path printed above — under an active workstream this is the workstream-scoped roadmap, NOT the literal .planning/ROADMAP.md) with the Write tool — the normal path. The guard allows this one shrink and deletes the sentinel. If the Write is blocked anyway, the sentinel was stale or consumed — re-run the printf and retry the Write.

Template for the composed content:

# Roadmap: [Project Name]

## Milestones

- ✅ **v1.0 MVP** — Phases 1-4 (shipped YYYY-MM-DD)
- 🚧 **v1.1 Security** — Phases 5-6 (in progress)

## Phases

<details>
<summary>✅ v1.0 MVP (Phases 1-4) — SHIPPED YYYY-MM-DD</summary>

- [x] Phase 1: Foundation (2/2 plans) — completed YYYY-MM-DD
- [x] Phase 2: Authentication (2/2 plans) — completed YYYY-MM-DD

</details>

Re-append Backlog section after the rewrite (only if $BACKLOG_SECTION was non-empty):

Append the extracted Backlog content verbatim to the end of the newly written ROADMAP.md. This ensures 999.x backlog items are never silently dropped during milestone reorganization.

Safety commit — commit archive files BEFORE deleting any originals:

INIT_REORG=$(gsd_run query init.complete-milestone)
if [[ "$INIT_REORG" == @file:* ]]; then INIT_REORG=$(cat "${INIT_REORG#@file:}"); fi
_gsd_field() { node -e "const o=JSON.parse(process.argv[1]); const v=o[process.argv[2]]; process.stdout.write(v==null?'':String(v))" "$1" "$2"; }
STATE_PATH=$(_gsd_field "$INIT_REORG" state_path)
ROADMAP_PATH=$(_gsd_field "$INIT_REORG" roadmap_path)
ARCHIVE_DIR=$(_gsd_field "$INIT_REORG" archive_dir)
MILESTONES_PATH=$(_gsd_field "$INIT_REORG" milestones_path)
PROJECT_PATH=$(_gsd_field "$INIT_REORG" project_path)
gsd_run query commit "chore: archive v[X.Y] milestone files" --files "${ARCHIVE_DIR}/v[X.Y]-ROADMAP.md" "${ARCHIVE_DIR}/v[X.Y]-REQUIREMENTS.md" "${ARCHIVE_DIR}/v[X.Y]-MILESTONE-AUDIT.md" "$MILESTONES_PATH" "$PROJECT_PATH" "$STATE_PATH" "$ROADMAP_PATH"

This creates a durable checkpoint in git history. If anything fails after this point, the working tree can be reconstructed from git.

MILESTONES.md and PROJECT.md are workstream-scoped the same way STATE.md/ROADMAP.md are (planningPaths(cwd).planning/.project) — under an active workstream this commits the actual files milestone complete wrote, not the root copies.

Remove REQUIREMENTS.md via git rm (preserves history, stages deletion atomically):

INIT_REORG=$(gsd_run query init.complete-milestone)
if [[ "$INIT_REORG" == @file:* ]]; then INIT_REORG=$(cat "${INIT_REORG#@file:}"); fi
_gsd_field() { node -e "const o=JSON.parse(process.argv[1]); const v=o[process.argv[2]]; process.stdout.write(v==null?'':String(v))" "$1" "$2"; }
REQUIREMENTS_PATH=$(_gsd_field "$INIT_REORG" requirements_path)
git rm "$REQUIREMENTS_PATH"

Append to living retrospective:

Check for existing retrospective:

ls .planning/RETROSPECTIVE.md 2>/dev/null || true

If exists: Read the file, append new milestone section before the "## Cross-Milestone Trends" section.

If doesn't exist: Create from template at ~/.claude/gsd-core/templates/retrospective.md.

Gather retrospective data:

1. From SUMMARY.md files: Extract key deliverables, one-liners, tech decisions
2. From VERIFICATION.md files: Extract verification scores, gaps found
3. From UAT.md files: Extract test results, issues found
4. From git log: Count commits, calculate timeline
5. From the milestone work: Reflect on what worked and what didn't

Write the milestone section:

## Milestone: v{version} — {name}

**Shipped:** {date}
**Phases:** {phase_count} | **Plans:** {plan_count}

### What Was Built
{Extract from SUMMARY.md one-liners}

### What Worked
{Patterns that led to smooth execution}

### What Was Inefficient
{Missed opportunities, rework, bottlenecks}

### Patterns Established
{New conventions discovered during this milestone}

### Key Lessons
{Specific, actionable takeaways}

### Cost Observations
- Model mix: {X}% opus, {Y}% sonnet, {Z}% haiku
- Sessions: {count}
- Notable: {efficiency observation}

Update cross-milestone trends:

If the "## Cross-Milestone Trends" section exists, update the tables with new data from this milestone.

Commit:

gsd_run query commit "docs: update retrospective for v${VERSION}" --files .planning/RETROSPECTIVE.md

Most STATE.md updates were handled by milestone complete, but verify and update remaining fields:

Project Reference:

## Project Reference

See: .planning/PROJECT.md (updated [today])

**Core value:** [Current core value from PROJECT.md]
**Current focus:** [Next milestone or "Planning next milestone"]

Accumulated Context:

• Clear decisions summary (full log in PROJECT.md)
• Clear resolved blockers
• Keep open blockers for next milestone

Check the project's branching_strategy (from init.execute-phase/init.complete-milestone). "none" skips straight to git_tag. For "phase" or "milestone", list the matching branches (by the configured prefix template); no branches found also skips to git_tag. Resolve the base branch through the single shared resolver, never a bare main/master fallback (Issue #1146):

BASE_BRANCH=$(gsd_run query git.base-branch)

If branches exist, present them and ask (AskUserQuestion): Squash merge (recommended) / Merge with history / Delete without merging / Keep branches. All three merge/delete options iterate every matching branch (phase strategy) or the one milestone branch, checking out BASE_BRANCH first and returning to the original branch after; both merge options strip .planning/ from staging first when commit_docs is false. "Keep branches" just reports them as preserved for manual handling.

Exact bash for each of the four options (squash, history-preserving merge, delete, keep): gsd-core/workflows/complete-milestone/detail/elaboration.md § 2.

If section_manifest is null or "git-tag" is in its included list: read and execute gsd-core/workflows/complete-milestone/steps/git-tag.md. Otherwise skip — do not read the file; proceed to git_commit_milestone.

Commit the REQUIREMENTS.md deletion (archive files and ROADMAP.md were already committed in the safety commit in reorganize_roadmap_and_delete_originals).

<milestone_naming>

Version conventions:

• v1.0 — Initial MVP
• v1.1, v1.2 — Minor updates, new features, fixes
• v2.0, v3.0 — Major rewrites, breaking changes, new direction

Names: Short 1-2 words (v1.0 MVP, v1.1 Security, v1.2 Performance, v2.0 Redesign).

</milestone_naming>

<what_qualifies>

Create milestones for: Initial release, public releases, major feature sets shipped, before archiving planning.

Don't create milestones for: Every phase completion (too granular), work in progress, internal dev iterations (unless truly shipped).

Heuristic: "Is this deployed/usable/shipped?" If yes → milestone. If no → keep working.

<success_criteria>

Milestone completion is successful when:

• Pre-close artifact audit run and output shown to user

• Deferred items recorded in STATE.md if user acknowledged

• Known deferred items count noted in MILESTONES.md entry

• MILESTONES.md entry created with stats and accomplishments

• PROJECT.md full evolution review completed

• All shipped requirements moved to Validated in PROJECT.md

• Key Decisions updated with outcomes

• ROADMAP.md Backlog section extracted before rewrite, re-appended after (skipped if absent)

• ROADMAP.md reorganized with milestone grouping (overwritten in place, not deleted)

• Roadmap archive created (milestones/v[X.Y]-ROADMAP.md)

• Requirements archive created (milestones/v[X.Y]-REQUIREMENTS.md)

• Safety commit made (archive files + updated ROADMAP.md) BEFORE deleting REQUIREMENTS.md

• REQUIREMENTS.md removed via git rm (fresh for next milestone, history preserved)

• STATE.md updated with fresh project reference

• Git tag created (v[X.Y]) (if git.create_tag enabled)

• Milestone commit made (includes archive files and deletion)

• Requirements completion checked against REQUIREMENTS.md traceability table

• Incomplete requirements surfaced with proceed/audit/abort options

• Known gaps recorded in MILESTONES.md if user proceeded with incomplete requirements

• RETROSPECTIVE.md updated with milestone section

• Cross-milestone trends updated

• User knows next step (/gsd:new-milestone)
