# Session 0003.0 — Transcript

> App: human-experience-filter-art

> Status: **FINALIZED**

## Launch prompt

> We should create a simulator, just something that is web-based, potentially that
> runs on localhost, running in a Docker container. It allows us to play virtually
> with the dials and see the content that has been curated, and then we can get to
> the actual physical stack. I think we want to make sure that we have the
> principles well done and the interface figured out, and then the middle will come
> in to play.

## Plan

Discovery session: explore the proposed **web experience simulator** and produce
its first artifacts — BDD scenarios and/or a spec — plus (chosen mid-session) an
implementation plan. Orientation:

```
/goal Discover the web-based experience simulator — produce BDD scenarios and/or
a spec, per human-experience-filter-art/docs/ROADMAP.md
```

## Pre-session state

- `main` clean and pushed at `b7f19e0`. Sub-projects 1 (catalog/selection) and 2
  (ingest/review) shipped; physical stack (3 Pi player, 4 firmware) ahead.
- `catalog/library.jsonl` empty (0 bytes) — tooling exists, no media ingested.
- No prior simulator artifacts. Memory pointed at sub-project 3 as next.

## Turn-by-turn arc

1. **Session gate / routing.** Opening prompt straddled coding vs. discovery;
   asked the operator → **discovery**. Ran `wgl-discovery-session-init`: claimed
   ID **0003** (`--type discovery`), verified clean pushed `main`, read memory,
   oriented from `docs/ROADMAP.md`.
2. **Brainstorming.** Accepted the visual companion (server on :61057). Settled
   scope via one-at-a-time questions:
   - Primary purpose → **feel the selection model** (curator's instrument).
   - Catalog source → **synthetic fixture catalog** (real catalog is empty).
   - Screen layout (browser mockups A/B/C) → **B · Curator's X-ray** (full
     transparency: pick + ranked pool + distances + brain/mood grid maps).
   - Approved the **additive `hef.selection.ranked_candidates()`** change.
   - **Include** the model knobs (weights, pool size, approved-only).
3. **Architecture.** Chose **Approach 1** — FastAPI + vanilla-JS, real
   `hef.selection` as single source of truth; Docker on localhost.
4. **Artifacts written + committed** (`76a9526`): design spec
   `docs/superpowers/specs/2026-06-04-experience-simulator-design.md` + 4 BDD
   feature files under `features/`. Self-reviewed; fixed the pick-determinism
   ambiguity (deterministic `rng=None` pick; pool = the room's shuffle-set).
   Operator approved the spec.
5. **Implementation plan** (chose "draft the plan now"): wrote
   `docs/superpowers/plans/2026-06-04-experience-simulator.md` — 7 bite-sized TDD
   tasks; self-reviewed for spec coverage / placeholders / type consistency.
   Committed (`e7ab227`).
6. **Memory + handoff.** Saved resume pointer
   `experience-simulator-ready-to-build.md` (+ MEMORY.md index) so the next
   coding session auto-surfaces the `/executing-plans` line.
7. **Finalize.** Push raced twice against concurrent session-claim commits (0003
   then 0004); rebased onto each (disjoint paths, non-destructive) and pushed.

## Cut state (end of session)

- `main` synced with origin. Discovery artifacts landed:
  - spec `40d7434`→`9cb4fb6` (rebased): `docs/superpowers/specs/2026-06-04-experience-simulator-design.md` + `features/*.feature`
  - plan `19a2dbc`→`ddec45d` (rebased): `docs/superpowers/plans/2026-06-04-experience-simulator.md`
- Final `main` tip: **`ddec45d`**.
- No code written this session (discovery only). Test suite untouched (baseline
  111 passed / 2 skipped).
- Visual-companion files persist under `.superpowers/brainstorm/` (gitignored).

## What lands on the operator's plate

- **Build is queued, not started.** The simulator exists only as spec + BDDs +
  plan. Next session executes the plan.
- **Structural gap (flagged, not blocking):** this app's `app.json` has no
  `contains:["bdd"]` or `contains:["spec-rfc"]` repo, so there is no external
  corpus/spec-RFC target — the discovery artifacts live in-repo (committed) by
  design. If a dedicated BDD/spec-RFC repo is ever wanted, register it in
  `app.json`.
- **Concurrent session 0004** was claimed during this finalize and may still be
  in flight.
- No deferred (low-confidence autonomous) decisions this session.

## Prompt the operator can paste into the next session

```
/goal Build the experience simulator — execute the plan task-by-task:
/executing-plans docs/superpowers/plans/2026-06-04-experience-simulator.md
```

Read `memory/experience-simulator-ready-to-build.md` first. The plan recommends
subagent-driven execution with review between tasks; the only shipped-code change
is the additive `hef.selection.ranked_candidates()` (Task 1).
