Session 0004.0 — Transcript

App: human-experience-filter-art Type: coding Start: 2026-06-05T03-32 (PST) · End: 2026-06-05T03-56 (PST) Goal: Execute the experience-simulator (curator's X-ray) implementation plan. Outcome: Shipped. All 7 plan tasks built TDD-first and merged to main via PR #3. Suite: 133 passed, 2 skipped. Docker image builds + serves.

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.
