Session 0006.0 — Transcript

App: human-experience-filter-art Type: coding Start: 2026-06-05T17-52 (PST) · End: 2026-06-05T18-15 (PST) Goal: /goal next — drive the roadmap to its next frontier item (sub-project 3, the player / machine-alteration engine), and build it. Outcome: Sub-project 3 slice 1 — the pure-logic alteration-engine + player core — built and MERGED to main via PR #5 (merge commit aeeed66). New player/ package; 56 new tests (189 passed / 2 skipped total). Sub-project 3 advanced from "next" to "in progress."

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 (light−dark)/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.
