Session 0014.0 — Transcript

App: human-experience-filter-art Start: 2026-06-24T06-58 (PST) End: 2026-06-24T08-29 (PST) Type: brainstorming Posture: careful Claude-Session: 50301aba-c534-4a7c-9f33-8b0881920ab2 Anchor: docs/ROADMAP.md sub-project 3 (Player Runtime) — content pipeline Status: FINALIZED

Launch prompt

Launch: /goal next → resolved from memory to the recorded Next /goal:
START A NEW SESSION for the content pipeline — sourcing full neutral video clips + processing + labeling. Brainstorm/scope it into a content-pipeline spec FIRST, deciding: (1) sourcing (strict-PD clips, which scales); (2) clip length + seamless-loop strategy; (3) labeling approach (static vs motion-tracked; hand-authored vs detection-assisted; same for affect); (4) format target (res/fps/codec for sim now + Pi later). Anchor fact: Right dream is real-time, no per-clip bake → pipeline is transcode + authoring, NOT ML baking.

Plan

Anchor: docs/ROADMAP.md sub-project 3 content pipeline. Roadmap-anchored repo (no Gitea issue tracker used 0001–0013); content pipeline is one cohesive Feature → design-eligible. See Deferred decisions for the R1 deviation.

Goal: Explore the content pipeline (source full neutral PD clips → process → label/author) and write its Solution-Design spec. Anchor fact: the Right dream is real-time (session 0013), so the pipeline is transcode + human authoring, not ML baking.

What happened (arc)

This opened as /goal next; the session gate resolved the stored Next /goal: from memory (content pipeline) and routed to brainstorming (the goal said "brainstorm/scope it into a spec first"). Init claimed session 0014 (careful posture, the brainstorming default), no concurrent sessions, clean main.

Orientation. Read the roadmap (sub-project 3), the scales-library/right-axis design (§1/§3/§4), the two session-0013 specs (real-time dream supersedes the SD bake; affect channel), and the current content shape (simulator/clips.py, manifest.json, setup_scales_media.py). Confirmed the key simplifier: the Right dream is real-time, so the pipeline is transcode + authoring, not ML baking.

Brainstorming (careful, agree-up-front → draft-whole → review-whole). Walked the four launch-prompt decisions as AskUserQuestion checkpoints:

Scale set → lean 5 (cosmos · orbit · forest/land · reef · abyss; microscopic dropped — thinnest PD-video pool).
Loop → crossfade loop (tail→head overlap).
Labels → motion-tracked, HYBRID (ML proposes where it can; hand-seed + classical tracker elsewhere). Surfaced that label semantics must always be hand-authored (a generic detector can't produce "siphonophore"/"z ≈ 0.04"); tracking only propagates box geometry.
Format → master + 1080p H.264 proxy.

Drafted the full spec docs/superpowers/specs/2026-06-24-content-pipeline-design.md, pushed to feature/content-pipeline, handed over the rendered Gitea URL for whole-document review. Operator chose "Approve + plan now".

Planning. Wrote docs/superpowers/plans/2026-06-24-content-pipeline-increment-1.md (Increment 1 = real footage, no ML): 9 bite-sized TDD tasks. Self-reviewed against the spec (coverage, types, one dead-variable fix). Operator chose "Execute now (subagent-driven)".

Execution (subagent-driven, 2-stage review per group). Implementer + reviewer subagents (sonnet), grouped by file coupling:

Tasks 1–3 (tools/pipeline/ffmpeg_ops.py pure builders) — DONE; review added an overlap<=0 test.
Tasks 4–5 (provenance.py, manifest.py) — DONE; review added append-fallback + N=1 self-wrap tests.
Task 6 (run.py runner + integration test) — the test gated on shutil.which and SKIPPED (ffmpeg not on PATH). Increment 1's goal is to prove the pipeline on real footage, so I hardened the runner to resolve the bundled imageio-ffmpeg (matching setup_scales_media.py) and switched duration probing to cv2 (no ffprobe dep — Pi-friendly). Re-run actually exercised real ffmpeg on the real forest base and surfaced a genuine bug: trim yields 1/0 framerate which xfade rejects (needs CFR) — fixed with fps=30 after each trim segment. Test now PASSES (proxy 1920×1080 verified via cv2). Closed an ffprobe-gap minor too.
Task 7 (client annotation-track interpolation, app.js) — DONE; node --check clean, API serves the track. Visual drift deferred to operator by-eye.
Task 8 (ring 3→5: orbit + reef placeholders) — DONE; /api/ring shows 5 scales
- 5 edges. Ring spin deferred to operator by-eye.
Task 9 (sourcing doc + ROADMAP + stale-docstring fix) — DONE.

Final whole-branch review: READY TO MERGE (no critical/blocking). 246 passed / 2 skipped. Operator chose "Merge to main now" → pushed, created PR #13 via the Gitea API, merged (delete branch), synced main, deleted local branch. Stamped the spec graduated on main.

Outcome

Content-pipeline spec (graduated) + Increment-1 plan (archived in-repo)
- Increment 1 implementation all merged to main (PR #13, merge bb5ecf0; spec stamp 73e5c4a). Suite 246 passed / 2 skipped.
New tools/pipeline/ package; keyframed annotation-track schema (client-interpolated, backward compatible); scale ring extended 3→5.
docs/content-sourcing.md (strict-PD sourcing procedure); ROADMAP updated.

Deferred decisions

R1 anchor (no Gitea issue): the brainstorming gate wants a non-epic type/* tracker issue as the design anchor. This repo has never used a Gitea issue tracker (roadmap-driven, 0001–0013), so the spec is anchored to docs/ROADMAP.md sub-project 3 — matching every prior brainstorming session here (0005/0007/0008/0013). Flagged rather than force-filing an issue that would break established repo practice; operator can request issue-tracking if wanted.
Session-type blur (operator-directed): a brainstorming session normally ends at the spec; the operator explicitly extended it through plan → execute → merge. Each transition was an explicit operator choice via AskUserQuestion, so the careful-posture gates were honored, not bypassed.
Crossfade duration source (minor, non-blocking): process_clip probes the duration from the source, not the post-frame mezzanine; GOP alignment can make the tail segment ±~33 ms off. ffmpeg handles EOF gracefully; imperceptible on calm footage. Noted for a future fast-motion clip.

Pending for next session

Operator by-eye review of Increment 1 in the sim: the track drift (water/fish boxes follow playback + loop seamlessly) and spinning the 5-scale ring cosmos→orbit→forest→reef→abyss→wrap. A dev sim (session-0013 live-reload) was running on :8000 during the session.

Next /goal

/goal content-pipeline Increment 2 — source real strict-PD bases per docs/content-sourcing.md (run each through tools/pipeline/run.py process_clip) + build the hybrid motion-track pass tools/pipeline/track.py + a simulator author mode; FIRST do the pending by-eye review of Increment 1. Per docs/superpowers/specs/2026-06-24-content-pipeline-design.md

Still-deferred (tracked in docs/ROADMAP.md, this repo's queue): real i2v ring transitions (need a generative-video model + adjacent real bases); Pi renderer + serial/firmware (simulator-first).
