conductor(deob_umbrella): Initialize Pass 2 de-obfuscation campaign umbrella

Pass 2 of 3 multi-pass research campaign. 5 folders total (1 umbrella + 1 warmup + 3 phase children).
- Umbrella spec.md (~400 lines): full design, philosophy, 3-layer deliverable, verification
- Multi-pass framing: Pass 1 = extraction (done), Pass 2 = de-obfuscation (this), Pass 3 = projection (future user-led)
- De-obfuscation philosophy: constructive type theory + Wildberger finitism + boundedness for knowledge + cycles/iteration explicit + etymology-aware
- 4 verification criteria: lossless, bounded, constructively typed, etymology-cited
- Multi-layer deliverable per video: translation (side-by-side) + replacement (re-encoded) + decoder (per-term etymology)
- Phase 0: USER action item (gather 3-10 samples of past de-obfuscation notes)

+# Video Analysis De-obfuscation Campaign (2026-06-21) — Pass 2 of 3
+
+**Status:** Active (spec approved 2026-06-21)
+**Owner:** Tier 1 Orchestrator (umbrella spec); Tier 2 Tech Lead (per-track execution)
+**Type:** Multi-track research campaign (5 folders total)
+**User-as-source:** The warmup is blocked on the user providing samples (Phase 0).
+
+This is **Pass 2 of 3** in the research campaign to penetrate the AI field. See [spec.md](./spec.md) for the full design and the user's de-obfuscation philosophy (constructive type theory, bounded forms, cycles/iteration explicit, etymology-aware).

+|---|-------|--------|-------|
+| Warmup | [../video_analysis_deob_warmup_20260621/](../video_analysis_deob_warmup_20260621/) | [ ] | Produces `report.md` + `prompt_template.md` from the user's past samples. User must provide samples first. **Blocks the 3 children below.** |

+- `[x]` shipped
+- `[!]` blocked
+
+## Cluster / phase legend
+
+- **Warmup** — research-style track; produces the initial lexicon + LLM prompt template
+- **Phase 1 (lexicon)** — refines the warmup's draft into a codified operational spec
+- **Phase 2 (pilot)** — applies the lexicon to 2 videos (1 foundational + 1 math-heavy) for validation
+- **Phase 3 (apply)** — applies the refined lexicon to the remaining 10 + synthesis
+
+## Multi-layer deliverable (per video)
+
+For each de-obfuscated video, the output is 3 files in `artifacts/<slug>/`:
+1. **`translation.md`** — side-by-side table: original expression ↔ re-encoded form
+2. **`deobfuscated.md`** — the re-encoded report (replacement; same 8-section structure as Pass 1)
+3. **`decoder.md`** — per-term decoder: form anchor, etymology, definition history, link to original section
+
+## Verification (4 criteria per deliverable)
+
+- **Lossless** — every Pass 1 concept is represented
+- **Bounded** — no `∞_val` or `∞_card`; all values are finite forms
+- **Constructively typed** — every expression has a type
+- **Etymology-cited** — every new term has a 1-line origin + 1-line definition history in the decoder
