## Plan

Execute `docs/superpowers/plans/2026-06-04-experience-simulator.md` via
`superpowers:executing-plans`: build the `simulator/` package — a FastAPI service
wiring the five dials to the **real** `hef.selection` code and serving a
vanilla-JS "X-ray" (picked piece + ranked candidate pool with distances +
brain/mood 5×5 maps), fed by a deterministic synthetic fixture catalog since
`catalog/library.jsonl` is empty. The only `hef/` change is additive:
`hef.selection.ranked_candidates()` with `select()` refactored onto it. 7 tasks,
TDD throughout; Docker + compose + `make` targets package it for localhost.

## Pre-session state

- Clean `main`, synced with `origin/main` at `ddec45d`; 111 tests green, 2 skipped.
- Memory pointer: simulator spec + BDDs + plan produced in discovery 0003
  (2026-06-04); next coding session runs `/executing-plans` on the simulator plan.
- Discovery session **0003** still `--INPROGRESS` (committed its artifacts to main
  but never finalized) — dormant, not actively editing the tree.
- `fastapi` not yet installed; `python` not on PATH (use `.venv/bin/python`).

## Turn-by-turn arc

1. **Session gate → coding init.** Classified the `/executing-plans` launch as a
   coding session; ran `wgl-session-coding-init`. Dry-run peek surfaced the
   in-flight 0003 placeholder; autonomous default → noted it and proceeded.
   Claimed session **0004**. Reconciled an initially-stale "ahead 2" read:
   local `main` == `origin/main` == `ddec45d` (the 0003 spec/BDD/plan commits are
   on origin). Verified clean baseline: **111 passed, 2 skipped**.
2. **Plan review.** Read the plan + `hef/selection.py`, `hef/catalog.py`,
   `pyproject.toml`. Critical review: all assumed symbols exist
   (`Coordinate`/`Weights`/`distance`/`candidates_for_mode`/`select`,
   `CONTENT_MODES`/`SELECTOR_MODES`; `Record` carries every fixture field). No
   blockers. Confirmed Docker present, `docs/USER_GUIDE.md` + `features/` exist.
3. **Workspace.** `using-git-worktrees` → native `EnterWorktree`
   (`worktree-experience-simulator`, branched from `origin/main`). Fresh `.venv`
   in the worktree; base package + pytest installed; baseline re-confirmed
   **111 passed, 2 skipped**.
4. **Tasks 1–7, TDD (red → green → commit each):**
   - **T1** `hef.selection.ranked_candidates()` + `select()` refactored onto it
     (single source of truth; behavior-preserving) — 24 passed (new + existing
     selection suite unchanged).
   - **T2** declare `simulator` package + `[project.optional-dependencies] sim`
     (fastapi/uvicorn/httpx); installed `-e ".[sim]"`; imports resolve.
   - **T3** `simulator/fixtures.py` — deterministic 625-cell synthetic catalog
     (all modes, mixed review status, no media) — 6 passed.
   - **T4** `simulator/app.py` — FastAPI `create_app`, `POST /api/select`
     (pick + ranked pool with distance/rank + coverage), `GET /api/catalog/meta`,
     real-catalog-or-fixtures loader, guarded static mount — 6 passed.
   - **T5** `simulator/static/` X-ray UI (dials, model knobs, ranked pool,
     brain/mood maps) + static smoke test — 7 passed. Manual browser eyeball
     substituted with live `curl` verification (no interactive browser): `/` 200,
     `/api/catalog/meta` 625 records all-modes/mixed-status, `/api/select` ranked
     pool ascending distances (1.0 → 1.41…), `none` → void, static assets 200.
   - **T6** Dockerfile + compose + `Makefile` (literal-tab recipes). First build
     **failed**: `package directory 'tools' does not exist` — `tools` is a
     declared setuptools package but wasn't copied into the image. Root-caused
     from the build log; fixed by adding `COPY tools ./tools`. Rebuilt → container
     serves (`/` 200, 625-record fixture catalog). Torn down.
   - **T7** USER_GUIDE "Playing with the simulator" section; **full suite: 133
     passed, 2 skipped** (baseline 111 + 22 new).
5. **Finish branch.** `finishing-a-development-branch` (autonomous): pushed branch
   as `experience-simulator`; created **PR #3** via the Gitea API
   (`wgl-gitea-admin` token mechanism, `git.benstull.org`); merged it (merge
   commit `618b691`); deleted the merged remote branch; FF'd local `main`;
   re-verified the merged result **133 passed, 2 skipped**; removed the worktree
   (all 7 commits confirmed ancestors of `main` first).
6. **Finalize.** Added `*.egg-info/` to `.gitignore` (editable-install artifact)
   and pushed to `main` (`40dfbfd`); updated memory; published this transcript.

## Cut state (final)

- `main` @ `40dfbfd`, clean, synced with `origin/main`. No open PRs, no dangling
  branches, worktree removed.
- **133 passed, 2 skipped.** Docker `make sim` builds and serves; `make sim-local`
  runs uvicorn. Simulator is operator-runnable on localhost.
- The simulator is a **curator's discovery tool**, not a roadmap sub-project — the
  roadmap frontier is unchanged.

## Deferred decisions

Autonomous-mode calls made without operator input:

1. **Dockerfile `COPY tools ./tools` (plan deviation).** The plan's Dockerfile
   copied only `hef`/`simulator`/`catalog`, but `pyproject.toml` declares
   `packages = ["hef", "tools", "simulator"]`, so the in-image editable install
   failed. Added the missing COPY. *Alternative:* trim `tools` from the package
   list — rejected (it's a real, used package). High confidence; the image now
   matches the declared packages.
2. **Manual browser eyeball → programmatic curl (T5 Step 7).** No interactive
   browser available, so verified the running server with `curl` (HTML, meta,
   `/api/select`, void, static assets) instead of visually. Behavior fully
   exercised, but no human visual confirmation of the rendered UI.
3. **Autonomous PR-merge instead of the interactive finish menu.** Per §6.5
   autonomous default + §5.4 (branch→PR→merge), pushed + opened + merged PR #3
   without surfacing the 4-option finish prompt. The preferred path was
   unambiguous and the merge is revertible.
4. **`*.egg-info/` gitignore committed straight to `main`.** Trivial one-line
   hygiene; landed directly rather than via PR.

## Next-session prompt

The simulator is shipped. The roadmap's next milestone is **sub-project 3
(Player Runtime / Pi)** — no spec/plan yet, so it starts with discovery.

```
/goal Develop sub-project 3 (Player Runtime / Pi): read the controls, call hef.selection.select(), play the chosen segment across the single panoramic projector, crossfade on change, dark on None — start with a discovery session to produce BDDs + spec, per docs/ROADMAP.md §3
```

Read first: memory `experience-simulator-ready-to-build.md` (what shipped + the
Dockerfile-copies-every-package gotcha), `pano-projector-nature-video.md` (single
pano projector, sub-project 5 dropped), and `docs/ROADMAP.md §3`. Open decisions
to settle: player stack (mpv/ffmpeg/custom), `approved`-only enforcement, and the
serial protocol framing shared with sub-project 4.

> Housekeeping: discovery session **0003** is still `--INPROGRESS` in
> `sessions/0003/` (artifacts long since merged) — finalize or close it out.
