Prerequisites

Before executing, read (in priority order — load essential state first, defer the rest):

1. .gse/status.yaml — current state (highest priority)
2. .gse/plan.yaml — living sprint plan (if it exists) — source of workflow trajectory
3. .gse/profile.yaml — user profile and preferences
4. .gse/config.yaml — project configuration
5. .gse/backlog.yaml — sprint tasks only (current sprint filter)
6. Remaining files loaded on demand during workflow

Workflow

Step 0 — Verify Pause State

Read status.yaml → session_paused and status.yaml → pause_checkpoint to confirm the project is in a coherent paused state before searching for a checkpoint to load. This step closes the read-side gap of the pause.md ↔ resume.md state symmetry: pause Step 3 writes session_paused: true + pause_checkpoint: checkpoint-{...}.yaml and resume Step 6 clears them, but until v0.62.2 these two fields were write-only — never consulted to drive resume behavior.

Skip conditions:

• If --list is specified, skip this step entirely (read-only listing has no state to validate).
• If --checkpoint FILE is specified, this step still runs but only emits an informational note on inconsistency — it does not block the explicit override.

Three coherence cases:

1. Coherent paused state — session_paused: true AND pause_checkpoint is non-empty AND the file .gse/checkpoints/{pause_checkpoint} exists on disk.

   • Use pause_checkpoint as the default checkpoint for Step 1 (overrides the "latest by filename" search).
   • Proceed silently.

2. Inconsistent paused state — session_paused: true BUT pause_checkpoint is empty OR the named file is missing on disk.

   • Report:

     Status marked as paused, but the named checkpoint cannot be located.
       pause_checkpoint: "{value or '(empty)'}"
       .gse/checkpoints/ contains: {N} file(s)
     

   • Present Gate decision:
     • Use latest (default if any checkpoint exists) — Continue with the most recent checkpoint by filename.
     • Repair status — Reset session_paused: false and pause_checkpoint: "" in status.yaml, then suggest /gse:go.
     • Discuss — Investigate the divergence with the user.

3. Not paused — session_paused: false (or absent for pre-v0.47.8 projects).

   • Report:

     No active pause detected (status.yaml.session_paused = false).
       Last activity: {last_activity} at {last_activity_timestamp}
       Available checkpoints: {N}
     

   • Present Gate decision:
     • Run /gse:go instead (default) — Switch to normal orchestration; resume is not the right command here.
     • Force resume from latest — Override and resume anyway (rare: e.g., recovery from manual state corruption).
     • Discuss — Investigate.

Step 1 — Load Checkpoint

1. If --list is specified:

   • List all files in .gse/checkpoints/ sorted by date (newest first)
   • Display: timestamp, status_snapshot.current_sprint, status_snapshot.current_phase, note (if any)
   • Exit

2. If --checkpoint FILE is specified:

   • Load the specified checkpoint file

3. Otherwise:

   • Use the pause_checkpoint confirmed by Step 0 case 1 if a coherent paused state was detected.
   • Otherwise (Step 0 case 2 "Use latest" or case 3 "Force resume from latest"), find the latest checkpoint in .gse/checkpoints/ (sorted by filename, newest first).
   • If no checkpoints exist: report "No checkpoint found. Use /gse:go to start." and exit.

4. Read the checkpoint YAML and extract: git_state.worktrees, status_snapshot, backlog_sprint_snapshot, last_task, note

Step 2 — Verify Worktrees

Run git worktree list to get the current worktree state on disk.

For each worktree recorded in the checkpoint:

Worktree is present

1. Check for external changes since the checkpoint:

   git log {saved_last_commit}..HEAD --oneline
   

   (executed within the worktree directory)

2. If new commits exist: mark as [CHANGED] — someone (or another session) modified this branch

3. If no new commits: mark as [OK] — unchanged since pause

4. Check for uncommitted changes: mark as [DIRTY] if any

Worktree is missing

1. Mark as [MISSING]
2. Check if the branch still exists: git branch --list {branch_name}
3. If branch exists: propose recreation:

   git worktree add {original_path} {branch_name}
   

4. If branch is also missing, consult the class-2 backup tags before declaring anything lost (DELIVER Step 0 tags every branch it deletes — spec §10.6 — Safety and Recovery):

   git tag -l "gse-backup/sprint-{NN}-{type}-{name}-deleted"
   

   • Tag exists and its commit is in main (git merge-base --is-ancestor <tag> main): report as [DELIVERED] — the work was merged and the branch cleaned up; the checkpoint is simply stale. Informational, no action needed.
   • Tag exists but its commit is NOT in main: report as [LOST] with recovery available — the Step 3 Gate offers Recover from backup tag.
   • No tag: report as [LOST] — manual intervention needed (spec §10.6 — Safety and Recovery).

No worktrees in the checkpoint (branch-only / none strategy)

If git_state.worktrees[] is empty, verify the current branch instead, with the same grid:

1. Compare git branch --show-current with git_state.current_branch — if different, note the branch switch in the report.
2. New commits since pause: git log {git_state.head}..HEAD --oneline → any output → [CHANGED], else [OK]. (If git_state.head is absent — checkpoint predating this field — skip this comparison with an Inform note.)
3. Uncommitted changes: git status --porcelain → any output → additionally [DIRTY] (this catches changes left uncommitted by the Pause Commit Gate option 3 or --no-commit, as well as edits made outside GSE between sessions).
4. Include the branch line in the Step 3 report with the same symbols as worktrees.

Step 3 — Report Worktree State

Display worktree verification results with symbols:

WORKTREES
  [OK]      .worktrees/sprint-02-feat-api      — TASK-003 (unchanged)
  [CHANGED] .worktrees/sprint-02-feat-auth     — TASK-004 (2 new commits since pause)
  [DIRTY]   .worktrees/sprint-02-doc-readme    — TASK-005 (uncommitted changes)
  [MISSING] .worktrees/sprint-02-test-unit     — TASK-006 (branch exists, propose recreate)
  [DELIVERED] .worktrees/sprint-01-feat-done   — TASK-001 (merged to main, cleaned up — stale checkpoint)
  [LOST]    .worktrees/sprint-01-feat-old      — TASK-002 (branch deleted, backup tag found)

If any worktrees are [MISSING] or [LOST], present Gate:

• Recreate — Recreate missing worktrees from their branches
• Recover from backup tag — for [LOST] entries with a backup tag (spec §10.6 — Safety and Recovery): git branch {branch_name} gse-backup/sprint-{NN}-{type}-{name}-deleted, then recreate the worktree
• Skip — Continue without them
• Discuss — Investigate what happened

[DELIVERED] entries need no Gate — mention them in the Step 4 briefing as already merged (stale checkpoint, nothing to recover).

Step 4 — Context Briefing

Present a summary of where the user left off:

SESSION RESUMED
  Paused: {checkpoint_timestamp} ({relative time, e.g., "2 days ago"})
  Sprint: S{NN} ({current_phase})
  Last activity: {last_activity}
  Last task: TASK-{ID} ({task_title})

Open the briefing with the session context: "You paused while working on {last_task}." (skip if last_task is empty).

If a note was attached to the checkpoint:

  Note: "{note text}"

Sprint progress:

  Tasks: {done}/{total} complete
  Budget: {used}/{total} complexity points
  Health: {health.score}/10

If .gse/plan.yaml exists with status: active, append a workflow trajectory block:

  Next in plan: {workflow.active}
  Pending:      {workflow.pending}
  Completed:    {count} of {expected_count}
  {if coherence.alerts is non-empty}:
  ⚠ Alerts:     {list of active alerts}

This is more precise than status.yaml.last_activity alone (which says "where we were" but not "where we're going"). For beginners, translate the activity names per P9 Adaptive Communication (e.g., reqs → "writing down what the app should do", produce → "building").

Step 5 — Propose Next Action

Determine the next action using, in priority order:

1. Primary — .gse/plan.yaml.workflow.active if plan.yaml exists with status: active. The workflow's active field is the declarative source of truth for "what comes next" (see orchestrator Decision Tree). This is more reliable than inferring from last_activity.
2. Fallback — status_snapshot.last_activity if plan.yaml is absent (Micro mode or pre-v0.20 projects). Use the table below.

Checkpoint State	Proposed Action
last_activity: /gse:produce, task in-progress	"Continue producing TASK-{ID}: {title}" → /gse:produce --task {ID}
last_activity: /gse:produce, task done	"All production done. Ready for review." → /gse:review
last_activity: /gse:review, fixes pending	"Review complete, fixes needed." → /gse:fix
last_activity: /gse:fix	"Fixes applied. Ready for delivery." → /gse:deliver
last_activity: /gse:deliver	"Sprint delivered. Time to capitalize." → /gse:compound
last_activity: /gse:compound	"Capitalization done. Ready to integrate." → /gse:integrate
last_activity: /gse:pause (nested)	Unwrap to the activity before the pause

Present the proposal and wait for user confirmation.

Step 6 — Finalize

1. Update status.yaml session state only:
   • session_paused: false
   • Reset pause_checkpoint: "" (empty string — preserves schema stability vs dropping the field; readers get a well-defined absence representation)
   • Update sessions_without_progress — compare current backlog.yaml TASK statuses against status.yaml → task_status_snapshot (map TASK-id → status written at the end of this step; treat an absent or empty snapshot as "first session" → reset to 0). If no TASK status has changed since the last session → increment sessions_without_progress by 1; if at least one has changed → reset to 0. Then refresh the snapshot: write the current map of {TASK-id: status} to status.yaml → task_status_snapshot. This drives the stale-sprint Gate (see /gse:go Step 4 — Stale Sprint Detection) and the coach mid_sprint_stall event trigger (feeds axes 3-4 — sprint velocity, workflow health; activates at >= 2).
   • Integrity-counter backstop — run python3 "$([ -s .gse/registry ] && cat .gse/registry || cat ~/.gse-one)/tools/counters.py" health; if "stale": true, emit the same Inform note as /gse:go Step 4 — Stale Sprint Detection (P16 integrity counters unmoved across ≥ 5 transitions — re-check spec §P16 counting obligations).
   • (Cursor fields last_activity, last_activity_timestamp are maintained centrally by the orchestrator after the activity closes — see plugin/agents/gse-orchestrator.md — section "Sprint Plan Maintenance", and gse-one-implementation-design.md §10.1 — Sprint Plan Lifecycle (v0.53.0). RESUME writes no cursor fields directly.)
2. The session is now active. Proceed with the accepted action or wait for user command.
