 - **White-noise generation** — runtime white/pink noise for that content position.
-- **Offline v2v variant pipeline** — author the pre-baked Right restyle variants
-  via the local flow-stabilized SD pipeline (now ~free, not a paid API — see the
-  scales-library/right-axis design §1/§4); a real multi-strength flow-stabilized
-  re-bake per base clip + the multilingual label/string tables + TTS. The
-  **scale-ring transitions** (forward/reverse per-edge morphs) are part of this
-  offline pipeline too.
-  - **Vertical slice done (session 0012):** the Right-variant half is
-    productionized and run for the **forest** scale — `simulator/bake_right_variants.py`
-    (the POC flow-restyle algorithm, repo-resident) bakes real strengths 1–4 on a
-    by-eye keyframe-strength ramp; forest now carries real Right variants in the
-    sim, so the dreamlike-axis look is judgeable on real footage. **Still
-    deferred:** real Right variants for cosmos/abyss (need their real strict-PD
-    bases sourced first) and the **real i2v ring transitions** (need a 2nd real
-    base + a generative-video model not in the POC). Plan:
-    [`2026-06-08-v2v-vertical-slice-forest-right-variants.md`](./superpowers/plans/2026-06-08-v2v-vertical-slice-forest-right-variants.md).
+- **Content pipeline + label track** — source strict-PD neutral bases, run them
+  through the offline pipeline, and author the annotation tracks that drive the
+  Left-HUD overlay. The Right dream is now **real-time** (Kuwahara WebGL shader,
+  session 0013 — no per-clip ML bake), so the pipeline is
+  **source → crossfade-loop → master+proxy transcode → hand-authored /
+  motion-tracked labels → manifest**, not ML baking. Historical note: the
+  flow-stabilized SD-turbo v2v bake (session 0012, `simulator/bake_right_variants.py`)
+  was superseded when the operator found the baked-SD Right "too fluid" and the
+  design pivoted to the deterministic real-time dream; `bake_right_variants.py`
+  is now parked. Spec:
+  [`2026-06-24-content-pipeline-design.md`](./superpowers/specs/2026-06-24-content-pipeline-design.md).
+
+  - **Increment 1 — deterministic tooling + 5-scale ring (session 0014) ✅ Done.**
+    `tools/pipeline/` (frame/loop/transcode/manifest, pure + unit-tested + an
+    opt-in integration test on real footage); the backward-compatible keyframed
+    annotation-track schema with client interpolation; and the **full 5-scale ring**
+    (cosmos → orbit → forest → reef → abyss) with orbit + reef as placeholder
+    scales alongside the existing cosmos/abyss/forest. Plan:
+    [`2026-06-24-content-pipeline-increment-1.md`](./superpowers/plans/2026-06-24-content-pipeline-increment-1.md).
+
+  - **Increment 2 — hybrid motion-track pass + author mode (pending).** The
+    `tools/pipeline/track.py` classical OpenCV tracker + optional ML detect+track,
+    plus a simulator **author mode** for reviewing/editing annotation tracks in the
+    browser. Real strict-PD bases for all five scales sourced per
+    [`docs/content-sourcing.md`](./content-sourcing.md).
+
+  - **Still deferred:** real **i2v ring transitions** (need a generative-video
+    model + adjacent real bases); Pi renderer + serial/firmware.
 - **Catalog model changes** — audio *source* + "neutral base" vs "altered
   variant" flag (sub-project 2 territory, design §13).

+
+For each scale, acquire a calm, neutral source clip from a **strict public-domain**
+US-government source, verify the license, then run it through the pipeline.
+
+| Scale  | Source                         | Where                              |
+|--------|--------------------------------|------------------------------------|

+**License check (mandatory):** confirm the asset is US-gov PD (17 U.S.C. §105) or
+explicitly CC0. "Free stock" (Pexels/Pixabay/etc.) is royalty-free but NOT public
+domain — do not use. Record a `Provenance` (tools/pipeline/provenance.py) per clip.
+
+**Run the pipeline** (replaces the placeholder bytes for a scale):
+
+```bash
+python -c "from tools.pipeline.run import process_clip; \
+  process_clip('downloads/<scale>.mp4', 'simulator/sample_media/<scale>', \
+  start=<in_s>, duration=<len_s>, overlap=<0.5..1.0>)"
+```
+
+This writes `simulator/sample_media/<scale>/base.mp4` (proxy) + `master.mp4`. Then
+author the labels (Increment 2: the hybrid track pass + simulator author mode) or
+hand-edit the annotation track for now (spec §4). The ring + manifest entry already
+exist; `process_clip` only replaces the media bytes.
