## Plan
Begin sub-project 3 (Player Runtime + alteration engine) per `docs/ROADMAP.md` §3
and the approved machine-altered-perception design (§4 alteration engine, §5 mood
grade, §6 7-way content dial, §7 intensity). Sub-project 3 is large (runtime
grading + overlay compositing + v2v variant selection + serial input + mpv/GPU +
white-noise DSP); this session ships **slice 1 — the pure-logic core** as a new
`player/` package, fully unit-tested with all I/O behind injected interfaces,
mirroring how sub-project 1 was the pure-logic dependency root. Process:
writing-plans → TDD → branch → PR → merge.
## Launch prompt
```
/goal next — drive the roadmap to its next frontier item.
Per project memory (session 0005, machine-altered-perception design SPEC merged
to main via PR #4), the roadmap frontier is sub-project 3: the player /
machine-alteration engine. This coding session builds that.
```
## Pre-session state
- `main` @ `77746e4` locally (behind `origin/main` by 2 — session 0005's finalized
transcript + this session's claim placeholder); fast-forwarded to `origin/main`
during init.
- Sub-projects 1 & 2 done/merged; design of record = the machine-altered-perception
revision (PR #4). No `player/` package and no sub-project-3 plan existed yet.
- Launch cwd was the stale, already-merged worktree
`.worktrees/feature-BuildSimulator11/` (branch `feature/machine-altered-perception-spec`,
remote gone) — same situation as session 0005.
## Turn-by-turn arc
1. **Gate / classify.** `/goal next` → unambiguously a coding session (roadmap
frontier = sub-project 3 build). Ran `wgl-session-coding-init`.
2. **Claim snag (same as 0005, kept in the record).** `resolve-app.py` reported
**ambiguous** — the nested worktree's `app.json` discovered alongside the main
clone's. Read the resolver to confirm root cause (`find_app_jsons` prunes
`.git/node_modules/…` but not `.worktrees/`). Worked around with
`WGL_APP_SCAN_DEPTH=4` (prunes the depth-5 worktree copy, keeps the depth-3 main
one). Claimed session **0006**, type coding, at `e694489`. Filed a plugin-feedback
note for the recurring gap (`feedback/2026-06-05T18-13-resolver-nested-worktree-ambiguous.md`).
3. **Baseline + branch.** Fast-forwarded the main clone; confirmed PR #4 merged;
created `feature/player-alteration-core` off `origin/main` in the worktree.
4. **Read the design.** Read ROADMAP §3 + the machine-altered-perception spec
(§4 alteration engine, §5 mood grade, §6 7-way dial, §7 intensity), and the
existing `hef/` conventions (frozen dataclasses, pure modules, heavy unit tests).
5. **Scoped the session → slice 1.** Sub-project 3 is too large for one session;
chose the pure-logic core (controls model, content-dial resolver, alteration
render-plan, player state machine) with all I/O behind injected interfaces, and
deferred the renderer/serial/white-noise/v2v/catalog slices (named in the plan).
6. **Surfaced a spec ambiguity (Deferred decision).** §3 "(2,2,2,2) neutral" vs
§4.2 (Left/Right stack as independent layers) vs §5 (mood center = identity)
cannot all be literally true for four independent knobs. Resolved with a
swappable calibration: brain `value/4`, mood `(lightdark)/4`; flagged for
operator confirm.
7. **writing-plans.** Wrote `docs/superpowers/plans/2026-06-05-player-alteration-core.md`
(6 TDD tasks, full code + tests, self-review against the spec).
8. **TDD implementation.** Red→green→commit per module: `player/controls.py`
(Controls, validation, parse), `player/content.py` (§6 7-way table),
`player/alteration.py` (RenderPlan: ColorGrade/AnalyticalOverlay/Restyle +
calibration helpers), `player/state.py` (Player state machine + Transition
kinds). Registered the package in `pyproject.toml`; updated ROADMAP §3.
9. **Verify.** Full suite green: **189 passed, 2 skipped** (the opt-in ffprobe
tests), 56 of them new player tests. No regressions.
10. **Ship.** Pushed the branch; created **PR #5** and merged it via the Gitea API
helper (merge commit `aeeed66`); synced the main clone; deleted the remote
feature branch.
11. **Wrap.** Filed plugin feedback, updated memory, finalized.
## Cut state
- `main` @ `aeeed66` (PR #5 merged). `player/` package present: `controls.py`,
`content.py`, `alteration.py`, `state.py` + 4 test files. Full suite 189 passed /
2 skipped.
- Sub-project 3 = **⏳ in progress**. Slice 1 done; remaining slices listed in
ROADMAP §3 and `[[sub-project-3-player-progress]]`.
- Working tree clean. Remote feature branch deleted; the local worktree remains on
the now-merged `feature/player-alteration-core` branch (harmless).
## Deferred decisions (operator plate)
Two low-confidence calls made autonomously this session — both flagged for operator
confirmation:
1. **Knob→strength calibration (§3 vs §4.2/§5 conflict).** §3 says "(2,2,2,2) is
neutral," but §4.2 (Left/Right stack as independent layers: overlay vs substrate)
and §5 (mood center = identity) conflict with that for four independent physical
knobs. Implemented: brain knobs `strength = value/4` (0 = off, 4 = max — full
range, honors §4.2 stacking), mood `tone = (light dark)/4` (equal dark/light →
identity, honors §5). Under this the un-altered base is `(0,0,·,·)` with
`dark==light`, **not** `(2,2,2,2)` — read as a vestige of the old coordinate-grid
*center*. The calibration is three one-line helpers in `player/alteration.py`;
flipping to a "centered at 2 = no push" convention is a localized change that
leaves the RenderPlan shape and all downstream logic untouched. **Recommend
operator confirm the intended panel UX.**
2. **Volume/Brightness granularity.** Modeled as `0..4` ints for uniformity with the
experience knobs and the Arduino's `0..4` quantization (roadmap §4). The spec
calls them "levels" without fixing granularity; revisit if the panel warrants
finer steps.
## Next-session prompt
The roadmap frontier is now the remaining sub-project-3 slices. Read
`[[sub-project-3-player-progress]]` and the slice-1 plan first. Two strong
candidates for the next slice — the **runtime renderer** (makes the core visible)
or the **serial framing contract + input adapter** (unblocks sub-project 4 in
parallel):
```
/goal Sub-project 3 slice 2 — settle the 3⇄4 serial framing contract and build the
USB-serial / keyboard input adapter that feeds the player a `Controls` stream
(unblocks sub-project 4), per docs/ROADMAP.md §3 and docs/superpowers/plans/2026-06-05-player-alteration-core.md.
Alternatively start the runtime renderer (mpv/ffmpeg + grade/overlay). First
confirm the open knob→strength calibration decision (§3 vs §4.2/§5).
```
Gotcha to carry forward: running from the nested `.worktrees/…` checkout breaks
`resolve-app.py` (ambiguous app.json) — run from the main clone, or use
`WGL_APP_SCAN_DEPTH=4` on claim and explicit `--sessions-*` flags on publish, until
the plugin fix lands.
