## 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:
1. Scale set → **lean 5** (cosmos · orbit · forest/land · reef · abyss; microscopic
   dropped — thinnest PD-video pool).
2. Loop → **crossfade loop** (tail→head overlap).
3. 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.
4. 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).
