Session 0010.0 — Transcript

App: human-experience-filter-art Start: 2026-06-07T23-09 (PST) End: 2026-06-07T23-22 (PST) Type: coding Status: FINALIZED Posture: autonomous (yolo) Landed: PR #8 (merge 638cf58) — calibration lock + dark-grade look fix

Launch prompt

Tune the alteration look by eye in the simulator (python simulator/setup_sample_media.py then make sim-local) and LOCK the knob→strength calibration into DEFAULT_CALIBRATION in player/alteration.py (+ a unit test) — settling the open session-0006 calibration decision. While there, judge whether more neutral "scales of nature" base clips + a real multi-strength flow-stabilized Right re-bake are worth doing next vs. moving to scale-ring navigation (endless encoder + AI zoom transitions). Keep deferring Pi renderer + serial/firmware. Read sub-project-3-player-progress memory + docs/superpowers/specs/2026-06-07-reconciled-simulator-alteration-slice-design.md (§8) first.

Pre-state

• main clean at e753a68 (then ff'd to the 0010 claim commit 7d2a306).
• Sub-project 3 slice 2 (sim alteration) merged in session 0009 (PR #7). Engine in player/alteration.py carried a Calibration + DEFAULT_CALIBRATION with behavior-preserving placeholder values; the knob→strength calibration had been the open decision since session 0006.
• Sample media already populated under simulator/sample_media/forest/ (base + Right strengths 1–4; only strength 4 is the real flow-stabilized restyle, 1–3 are ffmpeg blend placeholders). POC artifacts present in ~/hef-poc/out/.

The arc

1. Session open + grounding

• Classified the launch prompt as a coding session; ran wgl-session-coding-init, claimed session 0010 (no other sessions in flight). Verified clean pushed main baseline + CLAUDE.md stub.
• Read the resume context: sub-project-3-player-progress memory + the reconciled slice design §8 (open questions: calibration curve shape, grade-vs-overlay ordering, crossfade timing, placeholder fidelity).
• Inspected the engine (player/alteration.py), its test, the sim frontend (simulator/static/app.js), and the content/clip plumbing. Established that the calibration's three params (mood_gain, overlay_gain, right_variant_map) are the lock target, and that the grade look itself lives in app.js CSS filters (frontend), not in DEFAULT_CALIBRATION.

2. Tuning the look by eye (the key finding)

• python/ffmpeg weren't on the non-interactive shell PATH; used the project .venv. Baseline suite: 192 passed / 2 skipped.
• Viewed the operator's own POC renders in ~/hef-poc/out/ (all_axes.png, right_three.png, dark_frame.png, light_frame.png, lefthud_frame.png) — the by-eye-approved (session 0008) looks: tasteful cool-blue dark, warm golden light, soft dreamy flow restyle, legible analytical HUD.
• Booted the sim (uvicorn simulator.app:app) and drove it with headless Chrome (puppeteer-core) to screenshot the actual rendered look across all four axes at full knob, plus the whole-brain-dark corner.
• Finding: the sim's dark mood pole was rendering a full-frame hue-rotate(-cool*200deg) → rock turned orange, trees purple — a psychedelic look, exactly the "disorienting, not peaceful" effect the operator rejected in 0008, and nothing like the POC dark_frame. Light / Left / Right all looked good and peaceful. So the dark grade was the one thing blocking a likable look.

3. Dark-grade fix

• Replaced the hue-rotate in applyGrade (simulator/static/app.js) with: darken + slight desaturate on the video filter for the cool pole, plus a multiply-blended deep-blue wash (#tint, new element) that lifts shadows toward blue while preserving natural greens. Placed #tint below the SVG overlay so the Left HUD stays legible regardless of mood (resolves the §8 grade-vs-overlay ordering question → overlay above).
• Re-screenshotted: full dark now reads cool/somber with natural greens (matches POC dark_frame); whole-brain-dark corner peaceful + HUD legible; light/neutral unchanged (the warm path is algebraically identical for tone ≥ 0).

4. Locking the calibration

• With full tilt now tasteful on every axis (POC + sim evidence), the data says full knob = full look, 5 notches map 1:1 to the 5 discrete Right bakes, equal Dark/Light = identity → unity gains + linear variant map.
• Promoted DEFAULT_CALIBRATION from placeholder to a deliberately locked Calibration(mood_gain=1.0, overlay_gain=1.0, right_variant_map=(0,1,2,3,4)) with a provenance comment; this also confirms the session-0006 convention (0=off..4=max, equal Dark/Light = identity — no "centered at 2 = no push").
• Added test_default_calibration_is_locked pinning the literal constants. Suite: 193 passed / 2 skipped.
• Updated design §8 (calibration-curve + grade-vs-overlay resolved; dark-grade fix recorded).

5. Land + build-vs-next judgment

• Committed on feature/lock-alteration-calibration, pushed, opened PR #8 (Gitea API via wgl-gitea-admin helper), merged to main (638cf58), deleted the branch.
• Presented the build-vs-next judgment the prompt asked for. Recommendation (operator-confirmed via AskUserQuestion): move to scale-ring navigation next — pull in 1–2 cheap, true-PD neutral base clips (NASA cosmos, NOAA deep-sea) so the ring is demonstrable, build the endless-encoder control + placeholder zoom transitions in the sim, and defer the expensive real multi-strength flow-stabilized Right re-bake until the ring experience is liked (re-baking before the clip set is final risks wasted renders). Keep deferring Pi renderer + serial/firmware.

Cut state

• main @ 638cf58, clean, pushed. Suite 193 passed / 2 skipped.
• DEFAULT_CALIBRATION locked; dark-grade look fixed; design §8 updated; memory updated with the session outcome + the new Next /goal.
• Deferred (unchanged): Pi renderer, serial/firmware; the expensive Right re-bake.

Deferred decisions

• Locked DEFAULT_CALIBRATION to unity/linear autonomously. The operator asked to "tune by eye" and lock; I made the by-eye judgment (via POC renders + headless-Chrome sim screenshots) that full tilt is peaceful on every axis after the dark fix, so no softening of gains was warranted, and locked the unity/linear values. Alternative: soften mood_gain/overlay_gain (<1.0) so full knob is gentler — set aside because the evidence showed full tilt is already calm. The calibration stays fully parameterized, so flipping the feel is a one-line edit + the lock test if the operator disagrees on review.
• Dark-grade fix landed in the sim frontend (not the final renderer). The fix makes the simulator look right for tuning; the Pi/mpv renderer (later slice) will do proper grading. Recorded in §8.
• The build-vs-next direction was not a deferred call — it was put to the operator directly and confirmed.

Operator plate

• Calibration is settled and guarded; the long-open session-0006 decision is closed. The sim look is now likable on the one forest clip across all axes.
• Next session's first move is the /goal below (scale-ring navigation).

Next-session prompt

/goal Build scale-ring navigation in the simulator — add an endless rotary-encoder control (relative, vs the absolute 0-4 experience knobs) that walks a closed ring of neutral "scales of nature" clips with placeholder AI zoom/warp transitions between scales. Add 1–2 cheap, true-PD neutral base clips so the ring is demonstrable (NASA/Hubble cosmos + NOAA Ocean Exploration deep sea). Defer the expensive real multi-strength flow-stabilized Right re-bake until the ring is liked; keep deferring the Pi renderer + serial/firmware.
