 ## Launch prompt
 
-_(launch prompt not captured at claim time)_
+`/goal next` → resolved from memory to: **graduate + plan-and-execute the
+design-handoff spec** (SLICE-1 first; needs graduation/R2a).
+
+## Plan
+
+> Anchor: design `specs/2026-06-11-design-handoff-design.md` (content repo) —
+> anchors wiggleverse-dev-claude-plugin#95 (primary) + #93 (co-anchor).
+
+Resume of session 0069's design (`wgl-design-handoff`). This session:
+
+1. **Graduate** the spec — operator's recorded `/goal next` intent says
+   "graduate"; 0069 submitted it `proposed`. Stamp `status:graduated`
+   (frontmatter + in-doc Status cell), v0.1.0→v1.0.0, changelog row, re-submit
+   via `submit-spec.sh`. Confirm R2a eligibility.
+2. **Write the JIT plan** (all 5 slices; execution focus SLICE-1).
+3. **Execute SLICE-1** — the central engineering GUIDE/TEMPLATE per-UX-slice
+   `**Design:**` convention (doc-first; #93 doc half). Then continue into the
+   plugin slices (2→5) as the session allows.
+
+Concurrency: live concurrent sessions 0065 (content repo on its branch) + 0068
+at claim; 0035/0048/0058 are long-stale placeholders. SLICE-1 mutates the
+**engineering** repo and graduation pushes to **content** via submit-spec's own
+clone → isolate in worktrees per §5.4.
+
+## Deferred decisions
+
+## Progress
+
+**Graduated the design-handoff Solution Design (R2a).** Per the operator's
+recorded `/goal next` intent ("graduate + plan-and-execute"), stamped
+`status:graduated` (frontmatter + in-doc Status cell), bumped v0.1.0→v1.0.0, and
+added a changelog row, re-submitting via `submit-spec.sh` to content `main`. The
+eligibility gate confirms `ELIGIBLE … (R2a)`. **Gotcha:** the first `submit-spec.sh`
+run defaulted `--name` to my temp source basename, creating a stray duplicate
+`specs/design-handoff-spec.md` alongside the canonical
+`specs/2026-06-11-design-handoff-design.md`. Fixed: re-ran with the correct
+`--name`, then removed the duplicate via content **PR #5** (squash-merged).
+
+**Wrote the SLICE-1 JIT plan** —
+`docs/superpowers/plans/2026-06-11-design-handoff-slice-1.md`. Per the engineering
+GUIDE §7.1 one-slice-one-session convention, the plan covers SLICE-1 only; the
+SLICE-2→5 roadmap is carried from the spec for context (each its own future JIT
+session).
+
+**Shipped SLICE-1** — the per-UX-slice `**Design:**` field convention in the
+central engineering docs (`solution-design/GUIDE.md` §7.2 + `TEMPLATE.md`), value
+`pending` | path under `*-content/ui/designs/<issue#>-<slug>/` | `N/A — no UI
+surface`; `claude-design-vs-code.md` untouched. Engineering **PR #57**
+(squash-merged); convention verified live on engineering `origin/main`. Ran in an
+isolated engineering worktree (`session-0070-design-field`), torn down post-merge,
+branch deleted. This completes the **#93 doc half** (the backfill half lands in
+SLICE-4 — #93 stays open).
+
+**Next:** SLICE-2 (storage + unpack/normalize + commit → PUC-1 home step) — plugin
+repo, its own JIT session.
 
 ## Deferred decisions
 
 _Autonomous-mode low-confidence calls the driver made and would have
 liked operator input on. Appended as the session runs; surfaced at
-finalize. Empty if none._
+finalize._
+
+- **Graduated the spec on the strength of the recorded `/goal next` intent.**
+  Session 0069 deliberately submitted it `proposed` (not graduated); the operator
+  did not re-confirm graduation live this session. Treated the recorded next-goal
+  ("graduate …") as the operator's instruction. Reversible (re-submit `proposed`).
+- **Plan-history copy archived to content `plans/` only (canonical), no standalone
+  plugin-repo PR.** SLICE-1 touched only the `engineering` repo, so there was no
+  plugin PR to carry the plan-history copy; spinning a standalone plugin PR purely
+  for a secondary copy was judged unwarranted ceremony mid-concurrency. The
+  canonical archive (content `plans/`) is written at finalize.
+- **No plugin-repo worktree.** Confirmed-live concurrent same-app session 0065 is
+  in the **content** repo (on its own branch), not the plugin checkout; 0035/0048/
+  0058 are long-stale; 0068's status unknown but the plugin checkout was clean on
+  `main`. SLICE-1's mutations were isolated in an **engineering** worktree; no
+  substantive plugin-checkout writes were made. Judged low-contention (precedent:
+  sessions 0051/0062).
+
+## Session arc (turn-by-turn)
+
+1. Opened with `/goal next`; the session gate resolved the stored `Next /goal:`
+   from memory → "graduate + plan-and-execute the design-handoff spec (SLICE-1
+   first)"; classified planning-and-executing → `wgl-planning-and-executing`.
+2. Claimed session **0070** (posture yolo). Peek showed in-flight 0035/0048/0058
+   (stale) + 0065 (live, content repo) + 0068 (unknown). Baseline clean on
+   `main`@0.52.0.
+3. Read the spec; confirmed R2a only requires the design file to exist; graduated
+   the spec via `submit-spec.sh` (the `--name` gotcha + content PR #5 cleanup).
+4. Wrote the SLICE-1 JIT plan (one-slice-one-session per GUIDE §7.1).
+5. Executed SLICE-1 in an isolated engineering worktree: GUIDE §7.2 + TEMPLATE.md
+   `**Design:**` field → engineering PR #57 (squash-merged); verified live;
+   worktree torn down.
+6. Finalize: archived the plan to content `plans/`; no plugin bump / no version
+   gap → make-live skipped; commented progress on #95; updated memory + Next
+   /goal → SLICE-2; published this transcript.
+
+## Cut state / next session
+
+- **Landed:** design-handoff spec graduated (content `main`); SLICE-1 live on
+  engineering `origin/main`; plan archived to content `plans/`.
+- **Open:** #95/#93 remain open (the flow is not fully built); #93's backfill half
+  is SLICE-4. Remaining slices 2→5 are in the graduated spec §7.2.
+- **Next move:** `/goal next` resolves to SLICE-2 (storage + unpack/normalize +
+  commit → home step; plugin repo; depends on SLICE-1 ✓).
