## 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.
