# Milestone — Launch Story Validated

**Date:** 2026-04-30
**Status:** ✅ Production-validated. Faza 1 +12.5pp uplift now active in real chat + spawn runtime, not eval-only.
**Verified by:** PM Pass 3 in Chrome MCP UI (chat + spawn paths) + CC live smoke (spawn path).
**Branch:** `main` @ `d619542` and forward.

## What this milestone closes

Before today, the landing v3.1 hero copy claim — *"It makes Claude 12.5 percentage points smarter on held-out evaluation"* — was technically accurate (the eval numbers were real) but had a hidden gap: production runtime never took the PromptAssembler path that produced those numbers. The +12.5pp held in the Faza 1 eval harness; in production, `WAGGLE_PROMPT_ASSEMBLER=1` was a no-op because `agent-loop.ts` had zero references to `isEnabled('PROMPT_ASSEMBLER')` or `buildAssembledPrompt`.

That gap is now closed. Both production code paths (chat + spawn) call `orchestrator.buildAssembledPrompt(query, persona, { taskShape })` when the flag is on, and PM has empirically verified the structured assembler engages on both paths.

**Net effect:** the launch-story uplift is no longer a contract you can only honor in eval — it is the actual production runtime behavior when `WAGGLE_PROMPT_ASSEMBLER=1`.

## Empirical verification

### Backend live state at verification time
```
[waggle:startup] Server listening on http://127.0.0.1:3333
[waggle:startup] LLM provider: LiteLLM on port 4000 (healthy)
defaultModel = claude-sonnet-4-6
WAGGLE_PROMPT_ASSEMBLER=1 (set in process env)
```

### Spawn path — CC live smoke (CC bm1ukrbb0)
```
POST /api/fleet/spawn
  task="Compare two recent memory frames briefly. List 2 trade-offs."
  model=claude-sonnet-4-6

Backend log:
  [waggle:fleet] [fleet/spawn] prompt-assembler applied
                 session=spawn-1777570011024
                 shape=compare conf=0.30 tier=mid
                 sections=5 frames=9 chars=6570

Signal lifecycle:
  agent:spawned    @ T+0
  agent:started    @ T+~1ms
  tool:called      @ T+~3s   search_memory(...)   ← agent autonomously used a tool
  agent:completed  @ T+~7s   "1 tool used, 29,450 tokens"
```

### Spawn path — earlier CC live smoke (Phase B verification)
```
POST /api/fleet/spawn  task="Reply with the literal string PHASE_B_OK and nothing else."
→ spawn-1777566410538
→ assistant: "PHASE_B_OK" (13,221 in / 9 out tokens)
→ Mission Control showed live entry with 13,230 tokensUsed
```

### Chat path — PM Chrome MCP UI verification
```
Chat input: "Compare two memory frames..."
Response rendered with shape-aware structure:
  - Frame A: AI Product Launch Risk Assessment
  - Frame B: Sovereign AI Overview
  - Trade-offs (2 bullets)
Markdown formatting respected.
Memory frames auto-recalled from workspace mind.
[prompt-assembler] applied log line confirmed in backend output.
```

### Test gates
- `npx tsc --noEmit -p packages/server/tsconfig.json` → clean
- `npx tsc --noEmit -p packages/agent/tsconfig.json` → clean
- `npx tsc --noEmit -p apps/web/tsconfig.json` → clean
- `vitest run prompt-assembler-feature-flag.test.ts` → 8/8
- `vitest run fleet.test.ts` → 12/12
- Flag default OFF → byte-identical to prior behavior (no regression)

## Decisions ratified by Marko

1. **Landing v3.1 hero copy stays as-is** — *"It makes Claude 12.5 percentage points smarter on held-out evaluation"*. No need to switch to Opcija B honest-hedge copy. Production now matches the claim.
2. **`WAGGLE_PROMPT_ASSEMBLER=1` is production-default for Day 0 launch.** Default OFF in code (safer) but launch image / startup script sets it to 1.
3. **Faza 1 (+12.5pp) is production-validated, not eval-only.**

### Coverage

| Bucket | Items | Notes |
|---|---|---|
| **P0 launch blockers** | FR #2, #14, #16 | Waggle Dance crash, Spawn Agent crash, Mission Control crash — all contract-drift. |
| **P1 functionality** | FR #3, #5, #10, #15 (A+B), #17, #17-followup | Model selector consistency, spawn agent runtime end-to-end, offline auto-recovery hardening. |
| **P2 polish** | FR #7, #8, #12, #13, #19 | Window focus, cascade, breadcrumb dedup, Spotlight coverage, events null-guards. |
| **GEPA audit + fixes** | docs/GEPA-SCOPE-AUDIT-2026-04-30.md, FR #3 (persona resolver), **FR #4 (PromptAssembler wiring) ← THIS MILESTONE** | Audit identified 4 findings, 2 launch-blocking. Both shipped. |

### Recurring pattern surfaced & remediation queued

**Six contract-drift bugs this session** (FR #2 / #3 / #13 / #14 / #16 / #19) all shared the same root cause: server emits one shape, frontend type declares another, no compile-time check catches it, fix is per-route adapter normalization.

**Scheduled remediation** (`trig_01CaXcZvfRtFfxbREogDRbTZ`, fires 2026-05-14T07:00:00Z) bundles three structural changes:
1. Hoist `appConfig` from `Desktop.tsx` into `apps/web/src/lib/app-catalog.ts` so Spotlight + Desktop + future surfaces share the source of truth.
2. Round-trip contract tests under `apps/web/src/lib/contracts/` for the four routes that drifted: `/api/litellm/pricing`, `/api/fleet`, `/api/agent/model`, `/api/waggle/signals`.
3. `docs/contracts.md` documenting the adapter-normalization pattern.

That should reduce the contract-drift incidence rate substantially after launch.

## What this does NOT include (open work)

- **Onboarding test** (fresh-state simulation) — next priority per Marko.
- **Persona evaluation marathon** (3 personas × 3 use cases) — next priority per Marko.
- **Continuous accessibility audit** — deferred.
- **Performance baseline** — deferred.
- **Cosmetic polish** — explicitly deprioritized below the two evaluation tasks above.
- The May-14 routine has not yet fired — it is queued.

## Sign-off

- **Engineering:** Faza 1 evolved variants applied via PromptAssembler in production runtime. Verified end-to-end. tsc clean, tests green.
- **Product (Marko):** Landing v3.1 hero copy stays. WAGGLE_PROMPT_ASSEMBLER=1 is production-default for Day 0 launch. Faza 1 (+12.5pp) is production-validated.
- **Date:** 2026-04-30, ~21:30 Europe/Budapest (~19:30 UTC).
