Quarantine sorry blocks, fix RcloneIntegration proof, add ENE wiki re-ingest and ZFS setup.

Lean sorry audit (lake build passes, 3539 jobs): - FixedPointBridge: 10 sorrys quarantined with TODO(lean-port) — all blocked on Float→Q bridge lemmas (Q0_16/Q16_16 round-trip error bounds) - HyperbolicStateSurface: 3 sorrys quarantined — need Q16_16.sqrt error-bound and Q16_16.add_pos_of_pos lemmas - CostEffectiveVerification: 1 sorry quarantined; also fixed pre-existing struct/structure typo, Array.Repr, Real.abs syntax, and Bool/Prop mismatch - MMRFAMMUnification: 1 sorry quarantined — Array.foldl induction lemma missing - WaveformTeleport: constantWaveformAtFixedPoint_base native_decide was numerically false; replaced with sorry + TODO(lean-port) - RcloneIntegration: startTask_pending_non_increasing PROVED — only sorry fully closed, using List.partition_eq_filter_filter + List.filter_sublist - DiffusionSNRBias, GPUVerificationMetaprobe, QFactor, SSMS: already properly quarantined; verified build passes Infrastructure additions: - ene_wiki_body_reingest.py: 5-source priority resolver for ene.wiki_revisions text="" gap (TiddlyWiki → filesystem → Notion → package description → stub) - zfs-pool-setup.sh: stackcache pool (500G sparse vdev) with hot/warm/cold thermal-zone dataset hierarchy; requires reboot to 7.0.9-1-cachyos kernel Docs: - ROADMAP.md: mark Lean→Verilog/FPGA targets as LONG-TERM in Phase 6 - UNIFIED_SIGNAL_ARCHITECTURE.md: add FPGA-column deferral notice Generated with [Devin](https://cli.devin.ai/docs) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com>

+  WaveformTeleport.lean
+
+  Formalizes "waveform teleportation" via RG-flow invariant extraction:
+  instead of transmitting a raw waveform (O(TB)), extract its RG fixed-point
+  attractor (the scale-invariant shape) and reconstitute at the destination
+  from the attractor alone.
+
+  The teleport receipt proves roundtrip identity:
+    reconstruct (extract w) ~ w   (up to irrelevant UV modes)
+
+  This is the formal basis for "cheating" Glacier-class cold storage —
+  storing only the attractor token rather than the raw bytes.
+
+  No Float arithmetic anywhere in this file. All arithmetic is:
+    Q16_16  (UInt32 saturating 16.16 fixed-point)
+    Q0_16   (UInt16 pure-fraction)
+    Nat / Int intermediates only.
+
+  Depends on:
+    Semantics.FixedPoint      (Q0_16, Q16_16)
+    Semantics.LocalDerivative (StabilityClass)
+    Semantics.SemanticRGFlow  (BetaFunction, SemanticAttractor)

+-- ============================================================
+
+/--
+  A waveform is a finite sequence of Q16_16 samples together with an
+  SHA-256 digest stored as eight UInt32 words (256 bits total).
+  The SHA-256 is the identity anchor for the teleport receipt.

+  identifies a waveform's shape under RG coarse-graining.

+  This is what gets stored in Glacier instead of the raw bytes.

+# Creates a ZFS pool named "stackcache" backed by a sparse file on the local
+# NVMe btrfs filesystem.  This is Tier 0 of the three-tier cache:
+#
+#   Tier 0  stackcache  (local NVMe, ZFS, fast scratch)          ← this script
+#   Tier 1  node drives (rclone SFTP, see add-node-remote.sh)
+#   Tier 2  gdrive:research-stack-offload  (cold overflow)
+#
+# Why a sparse file instead of a raw partition?
+#   The NVMe is already partitioned (btrfs root).  A sparse file lets us
+#   carve out ZFS space without repartitioning.  Btrfs + ZFS file vdevs
+#   coexist safely; ZFS does its own checksumming and compression.

+# Pool layout:

+#   mounted at /mnt/stackcache

+# Thermal-zone dataset hierarchy (per Universal Computational Modeling substrate):

+#     stackcache/hot/db            — active SQLite scratch databases
+#   stackcache/warm                — batch I/O, moderate latency
+#     stackcache/warm/pgdump       — pg_dump / COPY TO overflow from Aurora RDS
+#     stackcache/warm/rclone       — rclone VFS cache directory
+#   stackcache/cold                — archival, high compression, sequential I/O
