Session 0009.0 — Transcript

App: human-experience-filter-art Start: 2026-06-07T22-41 (PST) End: 2026-06-07T23-03 (PST) Type: coding Status: FINALIZED

Launch prompt

Opened with /goal next — resume the goal recorded at the 0008 finalize. The session gate resolved the stored Next /goal: from memory:

Reconcile the 0007 simulator-alteration-preview design (UNMERGED) with the merged 0008 scales-library + flow-stabilized Right-axis design — resolve the Left-HUD conflict (baked-into-5×5-grid vs runtime Pango/HarfBuzz overlay) FIRST — then writing-plans → build the simulator-first slice: deterministic Dark/Light/Left + a flow-stabilized Right restyle over ONE neutral scale clip wired into the simulator. Defer Pi renderer, endless-encoder/serial, AI zoom-transitions.

Plan

Brainstorm the reconciliation (resolve Left-HUD first) → write a unified design doc → writing-plans → build & merge the simulator-first alteration slice.

Pre-state

  • On main at c99a669, clean tree; ran from the main clone (not a nested worktree — avoiding the session-resolver ambiguity gotcha flagged in 0008).
  • Two unmerged design threads: session-0007's feature/simulator-alteration-preview (baked-HUD 5×5 grid, design doc only, no code) vs. session-0008's merged scales-library/right-axis design (runtime-overlay HUD). The Left-HUD conflict between them was the thing to resolve.
  • Slice-1 engine (player/) on main: RenderPlan {grade, overlay, restyle} with a continuous Restyle.blend and a runtime AnalyticalOverlay. Simulator still on the old selection surface (/api/select, X-ray, fixtures.py).
  • 0008 POC artifacts present in ~/hef-poc/out/ (outside repo): real neutral.mp4 base + right_flow.mp4 flow-stabilized restyle.

Session arc (uncurated)

  1. Claimed 0009 (coding) from the main clone; resolver worked cleanly. Read both specs + memory in full.

  2. Surfaced the conflict precisely — it was 2-D, not 1-D. Beyond the Left-HUD rendering question, the two designs disagreed on the shape of the pre-baked set: 0007 made BOTH Left and Right a 5×5 grid of 24 authored clips; 0008 made only Right pre-baked and Left a runtime overlay. Key realization: 0008 §1.2 already IS the hybrid the operator floated ("authored box positions + runtime-shaped text") — authored annotation track for layout, runtime shaping for cheap i18n.

  3. Brainstorming → one operator question. Asked the single load-bearing fork (Left HUD: runtime-overlay+authored-track vs fully-baked vs defer). Operator chose runtime overlay + authored track (the 0008 / hybrid position). Everything else followed from approved material, so I proceeded autonomously.

  4. Found the engine was already most of the way there. The merged slice-1 engine already keeps a runtime AnalyticalOverlay — only 0007's unmerged doc proposed removing it. So the reconciliation was surgical: continuous Restyle.blend → discrete Restyle.variant; add AnalyticalOverlay.level; add a frozen Calibration. Wrote the reconciled design doc (brought the 0007 doc onto the branch so its superseded position is preserved + links resolve), committed.

  5. writing-plans → a full TDD plan (docs/superpowers/plans/...), then executed it task-by-task with executing-plans:

    • Task 1–2 (engine): Calibration+DEFAULT_CALIBRATION (behavior-preserving), Restyle.variant, AnalyticalOverlay.level, render_plan_to_dict. state.py needed no logic change (compares whole Restyle). Tests rewritten/green.
    • Task 3 (clips): simulator/clips.py manifest model; retired fixtures.py + test_fixtures.py.
    • Task 4 (API): /api/alteration + /api/clips; removed /api/select + /api/catalog/meta. Wrong turn: asserted retired POST returns 404, but the static catch-all yields 405 for an unrouted POST — relaxed the assertion to "404 or 405 = gone."
    • Task 5 (media): sample_media/manifest.json + setup_sample_media.py that copies the real POC neutral.mp4→base and right_flow.mp4→Right-strength-4 and ffmpeg-blends placeholder strengths 1–3. mp4s gitignored. Ran it — 5 files produced.
    • Task 6 (UI): rewrote simulator/static/ as the alteration preview (live grade via CSS filters, Right-variant <video> crossfade, live SVG Left overlay from the annotation track + string table, calibration panel, RenderPlan readout).
    • Task 7 (docs): parent design §4.3/§10 pointers; ROADMAP slice 2 done + deferred slices; USER_GUIDE simulator section rewritten.
    • Environment: python not on PATH; used .venv/bin/python throughout.

  6. Verified end-to-end. pytest -q → 192 passed, 2 skipped. Booted the sim on a scratch port: /api/clips returns the manifest (variant 0→base), the engine plan is correct by eye (left=3→level 3/intensity 0.75, right=4→variant 4, dark=4→tone −1.0), and the real right4.mp4 + base served as video/mp4.

  7. Shipped. Pushed the branch, created Gitea PR #7 via the keychain-token API helper, merged it (autonomous posture), synced main, re-verified tests green on the merged result, deleted my merged feature branch (local + remote).

Cut state (what landed)

  • PR #7 merged to main (merge 554eb50): the reconciliation design + the built simulator-first alteration slice (engine + simulator + media tooling + docs). 9 commits.
  • main green: 192 passed / 2 skipped. Sim verified booting + serving real media.
  • Memory updated: sub-project-3-player-progress.md (+ MEMORY.md index) — conflict resolved, slice 2 shipped, new Next /goal.
  • POC artifacts untouched in ~/hef-poc/ (still the source for setup_sample_media.py).

Deferred decisions

  • Brought the 0007 design doc into main + intended to delete the superseded branch. Decided autonomously to carry 2026-06-06-simulator-alteration-preview-design.md forward (so the reconciliation's links resolve and the superseded position is preserved) and to delete the now-stale feature/simulator-alteration-preview. The branch deletion (git branch -D / push --delete) was permission-denied by the harness — left in place. Safe to delete later (its content is in main); or the operator may want to keep it. Flagging rather than forcing.
  • Merged under autonomous posture without a separate /code-review. TDD + the written plan were the quality gates; no independent review pass was run before merge. Low risk for a slice this size, but noting it.
  • Used the POC's Yosemite clip as the sim's sample base. It's a "forest"-scale neutral clip, good enough to tune the look; framed in the manifest/USER_GUIDE as look-tuning only, not shipped content. Strict-PD scale-library sourcing stays a later slice — unaffected.
  • Calibration defaults are still behavior-preserving, not operator-tuned. The knob→strength calibration (open since session 0006) is now tunable by eye in the sim but not yet locked — that's the next goal.

Next /goal

/goal 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.
