+## Launch prompt
+
+```
+/goal Ensure that implementation never happens without an implementation plan.
+Ensure that implementation plans are never written without a solution design
+that includes that slice
+```
+
+## Plan (as captured live in the placeholder)
+
+**Goal:** Enforce the build chain in the plugin — no implementation without an
+implementation plan; no implementation plan without a Solution Design that
+includes that slice.
+
+Recursive by nature: honoring the goal while building it means design → plan →
+implement. Session opened as **coding** (operator choice).
+
+**Design decisions (operator-confirmed via AskUserQuestion):**
+1. Enforcement strength: **soft, house-style** (verify → route → ask-when-unsure
+   → fail open), matching the session-gate + finalize-on-goal posture. No hard
+   blocking hook.
+2. Artifacts (map to existing vocab): Solution Design = SPEC.md / spec-RFC
+   (§3.3) — or a committed `docs/superpowers/specs/` design doc where a repo
+   designs in-repo — that *includes the slice*; Implementation Plan =
+   `docs/superpowers/plans/` (writing-plans output); Implementation = via
+   superpowers:executing-plans.
+3. Scope: **focused enforcement layer only** on the current three session types
+   (keep spec/coding/discovery names); Effort B (full superpowers realignment +
+   spec-init→plan-init rename) stays deferred.
+
+**Approach (as planned):** Document the invariant canonically in
+SESSION-PROTOCOL.md (docs lead automation, §4.1), then wire coding-init to gate
+on it (G1: plan required before implementing; G2: covering Solution Design
+required before a plan) and route implementation through
+superpowers:executing-plans. Light touch on session-gate + spec-init. Bump
+0.17.0 → 0.18.0.
+
+## What actually happened to this work (reconstructed)
+
+The session's planned standalone enforcement layer at 0.18.0 was **not shipped as
+planned** — it was redirected:
+
+- **v0.18.0** (PR #13, `275c633`) instead became the *superpowers verbiage
+  rename* (the three session types → `brainstorming` / `writing-plans` /
+  `executing-plans`) — the operator's "effort B" realignment that this session's
+  Plan had explicitly deferred.
+- The build-chain invariant this `/goal` was chasing was then absorbed
+  **structurally** by the **two-session model** (v0.22.0, PR #22): `wgl-writing-plans`
+  folded into `wgl-brainstorming` (= reviewed spec), and `wgl-planning-and-executing`
+  came to *own the write-the-plan step* before executing. The build chain is
+  encoded in the session topology rather than as a separate soft-enforcement hook.
+
+So the `/goal` here is best read as a productive provocation: it surfaced the
+"design → plan → implement" chain that the later two-session model made
+load-bearing, rather than producing its own merged artifact.
+
+## Pre-existing note (carried from the live placeholder)
+
+> Session 0020 is a dead/unfinalized placeholder whose work (the
+> session-end-finalize-guard hook, PR #12) already merged; flagged for cleanup,
+> out of scope here.
+
+(That cleanup is the same 2026-06-08 pass that finalized this transcript.)
+
+## Cut state / outcome
+
+- No standalone merged artifact attributable to this session ID; its line of
+  thought lives on in v0.22.0's two-session model.
+- Plugin source is now at v0.23.0; tree clean and pushed.
+
+## Deferred decisions
+
+_None recoverable (context lost on /clear). The live placeholder's
+deferred-decisions section was empty._
+
+## Ended-unfinalized banner (original, from the SessionEnd guard)
+
+> ⚠️ This session ENDED WITHOUT A COMPLETED FINALIZE at 2026-06-07T15-58 (PST; reason: clear).
+> This placeholder holds only the last local checkpoint; the rich finalize
+> (narrative, memory update, PR/branch survey) did not run. The next session
+> should ADOPT and finalize this transcript via wgl-session-finalize, which
+> replaces this placeholder with the finalized record.
