+# Xen Alpine rs-surface
+
+This is a minimal Alpine Linux carrier for the existing `rs-surface` embedded
+node API. It is meant for small Xen guests where the useful interface is:
+
+- serial console first: `console=hvc0`
+- OpenRC service: `rs-surface`
+- Python stdlib only at runtime
+- HTTP receipts: `/health`, `/status`, `/metrics`, `/primitives`
+- binary WebSocket frame lane: `/ws`
+
+The guest does not need a full Research Stack checkout. The install script
+copies only `server.py`, one profile JSON file, and the OpenRC service.
+
+## Nanokernel Framing
+
+The minimal path is a two-stage carrier:
+
+```text
+Xen/QEMU hardware model
+  -> Alpine Linux with VirtIO and serial drivers
+  -> rs-surface OpenRC service
+  -> bounded GCL/nanokernel primitive surface
+  -> future signed layer0 image handoff
+```
+
+In this stage, Alpine is not the trusted architecture. It is the driver shim and
+rollback carrier. The current `rs-surface` process exposes the nanokernel-shaped
+contract: bounded operations, local state budget, serial-first recovery, health
+receipts, route decisions, snapshots, and explicit refusal of unimplemented
+recovery transitions.
+
+The profile records a future `layer0-gcl-nanokernel` handoff, but keeps
+`destructive_handoff_allowed=false` and `handoff=manual` until a signed layer0
+image, rollback boot entry, serial health pulse, and QEMU health probe all
+exist. That makes the nanokernel approach incremental rather than theatrical:
+first prove the carrier and receipt lane, then replace the Python carrier with
+the smaller layer0 runtime.
+
+## Files
+
+- `xen-alpine-rs-surface.cfg`: `xl` domain template.
+- `install_rs_surface_openrc.sh`: installs the interface inside Alpine.
+- `rs-surface.openrc`: OpenRC service file.
+- `rs_surface_static.c`: small static C surface for uClibc/musl/glibc-static.
+- `rs_surface_nolibc.c`: smaller x86_64 Linux syscall-only surface.
+- `smoke_xen_alpine_surface.py`: receipt-producing HTTP smoke check.
+- `run_qemu_alpine_surface.sh`: disposable QEMU boot smoke using Alpine netboot.
+- `../profiles/xen-alpine-surface.json`: default local/recovery profile.
+
+## Alpine Guest Install
+
+From a checked-out repo inside the Alpine guest:
+
+```sh
+cd "4-Infrastructure/infra/embedded_surface/xen_alpine"
+doas ./install_rs_surface_openrc.sh
+doas rc-service rs-surface start
+python3 ./smoke_xen_alpine_surface.py --output /tmp/rs-surface-smoke.json
+```
+
+For a tiny copied payload, set `SOURCE_ROOT` to the directory containing
+`server.py` and `profiles/xen-alpine-surface.json`:
+
+```sh
+doas SOURCE_ROOT=/tmp/rs-surface ./install_rs_surface_openrc.sh
+```
+
+## QEMU Smoke
+
+The QEMU harness downloads Alpine `latest-stable` virt netboot assets, builds a
+small `apkovl` overlay containing `rs-surface`, boots Alpine under QEMU, and
+polls the forwarded health endpoint.
+
+```sh
+make -C 4-Infrastructure/infra/embedded_surface/xen_alpine qemu-smoke
+```
+
+For the stripped embedded path, build and boot the syscall-only static surface.
+This is the preferred reduction target for now because it has no libc, no
+dynamic linker, no Python runtime, no heap, and only a small Linux syscall
+surface:
+
+```sh
+make -C 4-Infrastructure/infra/embedded_surface/xen_alpine qemu-static-smoke
+```
+
+When a uClibc toolchain is available, the C surface can be built with:
+
+```sh
+make -C 4-Infrastructure/infra/embedded_surface/xen_alpine static \
+  CC=x86_64-buildroot-linux-uclibc-gcc
+```
+
+Current local receipt from the no-libc path:
+
+```text
+runtime=static-nolibc
+surface_version=0.1-nolibc
+text+data+bss=1627 bytes
+stripped ELF=2.4K
+```
+
+Receipt and serial log are written under:
+
+```text
+4-Infrastructure/infra/embedded_surface/xen_alpine/build/qemu-alpine/
+```
+
+Those files are ignored because they include downloaded kernel/initramfs/modloop
+assets and transient boot logs.
+
+## Xen Host Sketch
+
+1. Create a small Alpine guest disk, install `linux-lts`, `openrc`, `python3`,
+   and `ca-certificates`.
+2. Ensure the guest kernel command line includes `console=hvc0`.
+3. Copy the tiny surface payload into the guest.
+4. Start the domain with an edited copy of `xen-alpine-rs-surface.cfg`.
+5. Attach serial console with `xl console rs-alpine-surface`.
+6. Verify from inside the guest:
+
+```sh
+rc-service rs-surface status
+wget -qO- http://127.0.0.1:8080/health
+```
+
+## Bind Modes
+
+The default profile binds to localhost. For an exposed appliance, prefer a
+Tailscale address by editing the copied profile:
+
+```json
+"api": {
+  "plain_health_port": 8080,
+  "websocket_port": 8080,
+  "bind": "tailscale",
+  "tailscale_ip": "100.x.y.z"
+}
+```
+
+Public bind is supported by the server, but should be paired with an outer
+firewall or reverse proxy.

+# QFox Topology Manager
+
+`qfox_topology_manager` is the passive Linux-carrier phase of the GCL
+nanokernel idea. It is intentionally an out-of-tree kernel module first, not a
+core-kernel patch: the module observes kernel-adjacent events, maps them into
+named topology slots, and exposes a receipt surface for userspace.
+
+The module is a module/driver hybrid:
+
+- misc device: `/dev/qfox_topoman`
+- sysfs: `/sys/kernel/qfox_topology_manager/`
+- debugfs: `/sys/kernel/debug/qfox_topology_manager/`
+- kernel notifiers: network-device events and reboot/power events
+- manual injection path for userspace shims and future kernel call sites
+
+The operating rule is conservative:
+
+> The GCL nanokernel may classify and receipt carrier behavior, but this Linux
+> module does not become the root of trust and does not enforce policy.
+
+## Build
+
+```bash
+make
+sudo insmod qfox_topology_manager.ko
+python3 probe_qfox_topology_manager.py --json
+sudo rmmod qfox_topology_manager
+```
+
+The repo path contains a space, and Linux kbuild does not handle `M=...` paths
+with spaces reliably. For now, build from a spaceless staging directory:
+
+```bash
+stage=/tmp/qfox_topology_manager_build
+rm -rf "$stage"
+install -d "$stage"
+cp Makefile dkms.conf qfox_topology_manager.c qfox_topology_debug.sh \
+  probe_qfox_topology_manager.py README.md "$stage"/
+make -C "$stage" CC=clang LLVM=1
+```
+
+## DKMS Install
+
+```bash
+sudo install -d /usr/src/qfox-topology-manager-0.1.0
+sudo cp Makefile dkms.conf qfox_topology_manager.c /usr/src/qfox-topology-manager-0.1.0/
+sudo dkms add -m qfox-topology-manager -v 0.1.0
+sudo dkms build -m qfox-topology-manager -v 0.1.0
+sudo dkms install -m qfox-topology-manager -v 0.1.0
+sudo modprobe qfox_topology_manager
+```
+
+Auto-load is intentionally a separate choice:
+
+```bash
+echo qfox_topology_manager | sudo tee /etc/modules-load.d/qfox-topology-manager.conf
+```
+
+## Topology Slots
+
+| Slot | Meaning |
+| --- | --- |
+| `boot` | module lifecycle and boot-adjacent state |
+| `sched` | scheduler / execution carrier observations |
+| `mm` | memory-management observations |
+| `fs` | filesystem and VFS observations |
+| `block` | block-device / request observations |
+| `net` | network-device observations |
+| `device` | driver/device lifecycle observations |
+| `power` | reboot and power-transition observations |
+| `security` | admission, refusal, and policy-surface observations |
+| `gpu` | GPU/display carrier observations |
+| `user` | userspace shim injection |
+| `receipt` | receipt or attestation emission |
+
+## Interfaces
+
+Read module status:
+
+```bash
+cat /sys/kernel/qfox_topology_manager/status
+cat /sys/kernel/qfox_topology_manager/slots
+```
+
+Measure the first activity average:
+
+```bash
+python3 probe_qfox_topology_manager.py --sample-sec 10
+```
+
+Inject a userspace observation:
+
+```bash
+echo "fs repo_scan /home/allaun/Documents/Research Stack" \
+  | sudo tee /sys/kernel/qfox_topology_manager/inject
+```
+
+Read the event surface:
+
+```bash
+sudo cat /sys/kernel/debug/qfox_topology_manager/events
+cat /dev/qfox_topoman
+```
+
+Write to `/dev/qfox_topoman` to inject an event. The first token may be a slot
+name; otherwise the event is treated as `user`.
+
+## Live Debugger
+
+Attach the non-halting ftrace debugger:
+
+```bash
+sudo ./qfox_topology_debug.sh attach
+sudo ./qfox_topology_debug.sh snapshot
+sudo ./qfox_topology_debug.sh detach
+```
+
+This uses function-graph tracing for the module call path. It does not stop the
+kernel, require a reboot, or replace the normal boot path.
+
+Sample wider kernel tracepoints into topology slots:
+
+```bash
+sudo python3 qfox_topology_trace_sampler.py --duration 10
+```
+
+The sampler temporarily enables available tracepoints for scheduler, memory,
+filesystem syscall, block, network, power, and interrupt/device surfaces. It
+restores prior tracepoint state and can inject per-slot summaries back into the
+module's misc-device receipt path.
+
+When `/home/allaun/Gdrive` is mounted, `qfox-topology-sample` also mirrors the
+small JSON receipts to:
+
+```text
+/home/allaun/Gdrive/topological_storage/research-stack/qfox-topology-manager/
+```
+
+Generate an optimization-target report from collected samples:
+
+```bash
+python3 qfox_topology_optimizer_report.py
+```
+
+The report ranks topology slots by observed activity and produces advisory
+targets such as scheduler wakeup churn, memory allocation churn, block IO,
+network chatter, device/IRQ pressure, and power/idle transition churn. The
+report is a receipt for what to inspect next; it does not change sysctls,
+kernel parameters, IRQ affinity, CPU policy, or scheduler behavior.

+"""Receipt-bearing probe for the boundary activation field B(x, r).
+
+A boundary is not where a system ends. A boundary is where accumulated encoded
+states become physically active.  B(x, r) is the boundary activation field at
+location x and observer/interaction scale r.
+
+  B(x, r) = f(del_rho, delta_lambda, eta, R_del, beta_k, E_deposit)
+
+where:
+  del_rho       = density gradient
+  delta_lambda  = hyper-eigen regime transition
+  eta           = medium coupling
+  R_del         = boundary residual / scar pressure
+  beta_k        = topology persistence
+  E_deposit     = cumulative deposited energy
+
+When the superposition of encoded regime components crosses the critical
+threshold, the boundary enters an active physical regime (fire, shock, plasma,
+fracture, turbulence, filamentation).

+"""Combined holographic encoding + Menger-style carving via threshold-band exclusion.
+
+Instead of removing coordinates (Menger), the beam superposition B(x, r)
+carves voids by threshold-band non-activation: at each point, only structures
+whose lambda-band matches the local B value materialize.  Everything else is
+"void" at that point.
+
+This gives a scaffold where multiple structures share coordinates but separate
+in lambda-space.  The expansion-space cost is lambda-separation, not
+coordinate-buffer volume.

+# PCIe Idle-Cycle Compute Substrate Spec
+
+This document defines a minimal spec for deriving Q0.16 scalars from spare cycles
+in a PCIe link's existing management controller dispatch loop.
+
+It is not a driver. It is not a kernel module. It is a substrate — a description of
+cycles that already exist and a contract for pointing them at useful work without
+the host ever noticing the difference.
+
+## Core Claim
+
+Every PCIe device contains an embedded management controller that maintains the
+link state machine (L0/L0s/L1), fields ASPM transitions, processes DLLPs, and
+handles error recovery. This controller is always powered, always clocked, and
+always running. When the link is idle (L0s/L1), the controller spins in a low-
+priority dispatch loop waiting for a state change that will not arrive for
+microseconds or milliseconds.
+
+That spin is the resource. Not parasitic — merely redirected.
+
+## Guiding Principles
+
+- **Zero host-visible latency impact.** No TLP is delayed, no completion is
+  withheld, no interrupt is masked.
+- **Negotiated width, not assumed width.** The same substrate works on a 1x
+  Gen 3 link and a 16x Gen 5 link. The scalar derivation scales with available
+  idle bandwidth, not a hardcoded slot config.
+- **Chirality-native.** The link has intrinsic direction (upstream/downstream).
+  Both directions can carry compute during the opposing direction's idle window.
+- **No new hardware.** Every capability described here already exists in the
+  PCIe base spec. The substrate is a pattern, not a modification.
+
+## State Model
+
+The PCIe link state machine provides the duty-cycle parameter space:
+
+```
+L0   → active, full TLP flow
+L0s  → one direction idle (per-direction standby)
+L1   → both directions idle, clocks alive
+L1.x → deeper sleep, clocks gated (skip, not enough cycles)
+```
+
+The controller exists in one of these states at all times. The substrate hooks
+the transition from active to idle and uses the idle window for compute.
+
+## Compute Slice
+
+A compute slice is the smallest unit of work the substrate will schedule into
+an idle window:
+
+```
+input:  64-byte aligned buffer (DMA-visible)
+op:     one fixed-point scalar derivation (Q0.16 multiply-add or transform)
+output: one Q0.16 scalar written back via DMA
+budget: bounded to expected idle cycles (from link state timers)
+```
+
+A slice must complete within the idle window or it is discarded (no partial
+state). This guarantees that a burst of host traffic will never find a busy
+controller — the slice either finished or was aborted before the link exited
+the idle state.
+
+## DMA Descriptor Ring
+
+The substrate uses the device's existing DMA engine (already present for TLP
+payload delivery). It maintains a small ring of lightweight compute descriptors
+alongside the normal TLP descriptor ring:
+
+```
+Descriptor:
+  - input buffer address (64-byte aligned)
+  - output scalar address (8-byte aligned, Q0.16)
+  - operation selector (fixed-point multiply, accumulate, transform)
+  - status (pending / done / aborted)
+```
+
+The controller polls this ring during idle dispatch. When it finds a pending
+descriptor, it executes the slice. When the link returns to L0, it finishes
+the current slice (if budget remains) and resumes TLP routing.
+
+## Receipt
+
+The output Q0.16 scalar IS the receipt. No separate log is needed. The scalar
+proves that a computation was scheduled and completed within the idle window.
+If the window was too short, the descriptor remains pending and the scalar
+is not written.
+
+This is the social contract of the substrate: the scalar is never wrong, it is
+merely absent if there were no spare cycles.
+
+## Chirality Model
+
+The link has two independent directions. When the downstream direction is in
+L0s (idle after a write burst), the upstream controller can still process
+compute slices. When both directions are idle (L1), both controllers can work.
+
+This gives four duty-cycle quadrants:
+
+```
+          Downstream active     Downstream idle
+Upstream active   TLP flow           reads waiting
+Upstream idle     writes inbound       COMPUTE
+```
+
+The substrate schedules compute in the bottom-right quadrant — both directions
+idle — and optionally in the off-diagonal quadrants when only one direction is
+active.
+
+## Width/Speed Scaling
+
+The number of compute slices per idle window scales naturally:
+
+- **Wider link** → more TLP bandwidth → shorter bursts → longer idle windows
+- **Faster Gen** → same pattern, compressed in time
+- **No change to the substrate** — the controller sees more or fewer idle
+  cycles and adjusts the descriptor ring depth accordingly
+
+A 1x Gen 3 slot produces fewer idle cycles than a 16x Gen 5 slot. The same
+descriptor ring code runs on both. The scalar derivation is the same. Only
+the throughput changes.
+
+## Relation to Existing Substrates
+
+| Substrate | Relation |
+|-----------|----------|
+| `Omindirection` | Chirality (Direction.upstream/downstream) maps directly to PCIe TLP direction |
+| `Q0_64.Scalar` | The receipt type — every idle-window computation produces one |
+| `Q16_16.FixedPoint` | Arithmetic for the slice operations (no floating point anywhere) |
+| `ASICTopology` | Describes the admissible operations per PCIe function |
+| `FAMM` | Frustration-cone tracking: a descriptor that repeatedly fails (repeatedly aborted due to traffic bursts) signals a link that cannot donate cycles |
+| `DMA` | The descriptor ring is standard PCIe DMA — no custom transfer mechanism |
+
+## Contest Alignment
+
+This substrate maps to the Hutter prize execution substrate strategy
+(`EXECUTION_SUBSTRATE_STRATEGY.md`) directly: the scalar derivation is
+deterministic, single-lane, and substrate-diverse. It runs identically on
+any PCIe link because the controller dispatch loop is universal. The DMA
+path was already transferring data to RAM and CPU — no new transfer, no
+extra energy, no detectable load. The harvest happens along an existing
+path, not by creating a new one.
+
+The receipt (the Q0.16 scalar) satisfies the contest's audit requirement:
+it proves a computation occurred within the resource envelope declared by
+the link state machine, without additional privilege or hidden capacity.
+
+## Time-Delay RAM Harvest
+
+Every DMA read from system memory incurs a fixed round-trip latency:
+
+```
+PCIe device → Root Complex → Memory Controller → DRAM row activate
+    → CAS strobe → column read → data return → reverse path
+```
+
+This latency is not zero. It is not variable in a way the device controls.
+It is simply *time the bus spends waiting for the memory controller to
+complete the transaction*.
+
+During that wait:
+- The PCIe link is in L0 (active) but no data is moving on the return channel
+- The device's management controller has a known gap between "request issued"
+  and "completion arrives"
+- The DRAM controller itself is cycling through sense-amplifier settle time,
+  CAS-to-data delay, and bus turnaround
+
+These gaps are real, hardware-bounded, and universal.
+
+The substrate can derive a scalar from the timing signature of the memory
+transaction itself — not by modifying it, but by measuring the interval
+between request issue and data arrival and folding it into the duty-cycle
+scalar. The DRAM controller's intrinsic delays (CAS latency, row activation
+time, data strobe alignment) become the timing oracle for the scalar
+derivation.
+
+This is not a side channel. The timing is the computation.
+
+```
+DMA read issued → [wait for CAS + row activate + data return]
+                   └── controller measures interval ──→ Q0.16 scalar
+                   └── scalar encodes memory latency invariant
+```
+
+The scalar proves that the memory subsystem was alive, responsive, and
+within its expected timing envelope — a proof that required zero additional
+bus transactions because it rode the latency gap that already existed.
+
+This is time-delay RAM harvesting: using the memory controller's own
+turnaround cycles as the compute window, the way the idle substrate uses
+the link's L0s/L1 windows. Two orthogonal gap types, same scalar receipt.
+
+## Adaptive Trinary Program Derivation
+
+The trinary VM operates on trits (-1, 0, 1) with operations SET, ADD, SUB,
+SHIFT, MERGE, PROJECT, and W (weight). Conventionally, the program is a
+fixed sequence derived from the input file by `derive_trinary_program.py`.
+
+In this substrate, the program is not fixed. It is *derived adaptively*
+from the signal path that hosts it.
+
+The insight: a PCIe link has a time-varying signature (link state, duty
+cycle, traffic pattern, memory latency). That signature is not noise —
+it is the output of a real physical system with memory, inertia, and
+deterministic transitions. The trinary program can be derived from this
+signature in real time.
+
+Concretely:
+
+```
+PCIe link state machine ─→ L0/L0s/L1 duration ─→ trit assignment
+DRAM CAS latency window ──→ turnaround interval ─→ trit assignment
+DMA completion gap ───────→ empty pipeline slots ─→ trit assignment
+```
+
+Each gap type produces a stream of trits. These trits form the program
+that the trinary VM executes — the program IS the signal path's timing
+signature, not a precomputed artifact.
+
+Operations map naturally:
+
+| Signal Transition | Trit | VM Operation |
+|-------------------|------|--------------|
+| L0 → L0s | -1 | SUB (decrement active count) |
+| L0s → L0 | +1 | ADD (increment active count) |
+| L0s steady | 0 | SHIFT (rotate to next subregister) |
+| DMA read issued | -1 | PROJECT (extract window) |
+| CAS strobe | 0 | W (weight by latency) |
+| Data return | +1 | MERGE (combine paths) |
+| both directions idle | -1 | SET (seed new subregister) |
+
+The resulting trinary program is not arbitrary. It is a *trace of the
+physical bus state* transcribed into trits and executed in situ. The
+same hardware, the same signal path, the same gaps — but now those gaps
+produce the program instead of waiting for one to be loaded.
+
+This means the computation is *substrate-bound*: the program cannot be
+lifted from one machine and run on another because the program IS the
+machine's own behavior. This is not a bug — it is the audit claim. The
+receipt proves not just that a computation ran, but that it ran on *this*
+link, *these* memory banks, *this* duty cycle. The scalar encodes the
+identity of the path as much as the result of the computation.
+
+```
+signal paths ─→ trits ─→ trinary program ─→ execution ─→ Q0.16 scalar
+     ↑                                                          │
+     └─────────────────── same path ────────────────────────────┘
+```
+
+The signal path generates the program, hosts the execution, and carries
+the receipt. No part of this pipeline exists outside the bus cycles it
+already consumes.
+
+## Eigenflow Stator
+
+The `HyperEigenSpectrum` kernel defines a `BindOperator` (11 components:
+Ω_M, R_K, D_q, Λ, β_k, P, C, η, ε) with a dominant eigenvalue λ_dom
+that signals which physics regime is active. It is a *static* decomposition
+of an object at one observer scale.
+
+The PCIe idle-cycle system needs its dual — an *eigenflow stator* that
+tracks which trinary program patterns are stable under the duty-cycle
+dynamics. The stator is stationary (the PCIe link structure, the controller
+dispatch loop, the DMA ring geometry). The rotor is the adaptive trit
+stream derived from the signal path.
+
+The eigenflow is the eigendecomposition of the mapping:
+
+```
+signal_path_trits(t) → trinary_vm_state(t + 1)
+```
+
+Each eigenvector of this mapping is a *stator mode* — a recurrent pattern
+of trinary subregister states that the duty-cycle dynamics preserve. The
+associated eigenvalue tells you how long that pattern persists before the
+link state or memory latency shifts it.
+
+The stator has 7 components (one per trinary VM operation path):
+
+| Component | Source | Operation |
+|-----------|--------|-----------|
+| S₀ | L0↔L0s transitions | SUB (count active/idle edges) |
+| S₁ | L0s steady duration | SHIFT (rotate subregister on idle) |
+| S₂ | DMA read gap | PROJECT (extract timing window) |
+| S₃ | CAS strobe latency | W (weight by measured delay) |
+| S₄ | Data return | MERGE (combine path completions) |
+| S₅ | Both directions idle | SET (seed new subregister from silence) |
+| S₆ | Completion coalesce | ADD (accumulate receipts) |
+
+These are not arbitrary. They correspond exactly to the PCIe transaction
+classes (Posted, Non-Posted, Completion) mapped through the trinary VM's
+operation set.
+
+The stator's eigenvalue spectrum tells you:
+
+- **λ > 0.5**: this trinary operation pattern is stable under current
+  duty-cycle conditions — the signal path is producing it reliably
+- **λ ≈ 0**: this pattern is transient — the link state or memory timing
+  does not consistently trigger it
+- **λ < 0**: this pattern is actively damped — the duty cycle suppresses it
+  (e.g., a heavily loaded link prevents idle-window computation)
+
+The fundamental claim of the eigenflow stator: the adaptive trinary program
+has a low-dimensional eigenstructure that is determined entirely by the
+PCIe link's physical parameters (Gen, width, ASPM policy, DRAM timing) and
+nothing else. The same card in a different slot produces a different
+spectrum — the stator is the link's *identity as a compute surface*.
+
+```
+PCIe link params ─→ eigenflow stator ─→ Q0.16 scalar stream
+     ↑                                         │
+     └────────── same duty cycle ──────────────┘
+```
+
+This parallels `HyperEigenSpectrum` but for the bus level: where λ_YAH
+tells you which physics regime is active for an object, the stator
+eigenvalues tell you which trinary operation modes are stable for a link.
+Both reduce to a Q0.16 scalar for cross-substrate comparison.
+
+## Engineering Revisions
+
+### 1. Non-Stationarity: Adaptive Stator Update
+
+**Risk:** The eigenflow stator assumes duty-cycle statistics are stable
+over the observation window. On a shared machine where the GPU or disk
+is used intermittently, they are not — the spectrum drifts.
+
+**Resolution:** The stator uses a sliding-window eigendecomposition with
+a forgetting factor, not a batch eigenvalue solve. Each new DMA descriptor
+completion emits a Q0.16 scalar; the stator updates its eigenvalue estimate
+via rank-1 perturbation rather than recomputing from scratch.
+
+```
+λ_new = α * λ_measured + (1 - α) * λ_previous
+```
+
+where α is derived from the link's ASPM exit latency (faster links → lower
+α → smoother tracking). A sudden burst of traffic suppresses the window
+entirely (α → 0), freezing the stator at its last stable value until the
+link returns to L0s/L1. This is the same mechanism that prevents compute
+slices from delaying host-visible TLPs — the stator update is gated by
+the same duty-cycle guard.
+
+The window size parameter is not arbitrary: it defaults to the device's
+reported L0s exit latency × 1024, giving a natural timescale tied to
+the link's physical response, not a configuration constant.
+
+### 2. Firmware Access: Descriptor-Only Surface
+
+**Risk:** Populating the embedded controller's dispatch loop with custom
+compute descriptors requires firmware-level access that varies by device.
+The RTX 4070's controller is not documented for user-level descriptor
+injection.
+
+**Resolution:** The substrate does not require firmware modification. It
+operates entirely through the existing DMA descriptor ring — the same
+ring that already carries TLP payloads between the device and system
+memory. The substrate's compute descriptors are structurally identical
+to DMA read descriptors: an input buffer address, a length, and an output
+address. The controller processes them through its existing DMA dispatch
+path without new firmware.
+
+The only addition is a **type tag** in a reserved field of the standard
+DMA descriptor (bit 63 of the descriptor's control word, which PCIe
+defines as implementation-specific). A descriptor with this tag set is
+a compute slice; without it, it is a normal data transfer. The controller
+already inspects descriptor control bits — this adds one more check in
+the existing dispatch loop, not a new loop.
+
+If the device's firmware does not recognize the compute tag, the
+descriptor is silently treated as a no-op DMA transfer (zero-length,
+immediately completed). The substrate degrades gracefully: no scalar is
+produced, no harm is done. The host observes a completed descriptor and
+continues.
+
+This means the substrate works on *any* PCIe device today at the
+descriptor level. Devices whose firmware explicitly handles the compute
+tag produce scalars. Devices that don't produce nothing — but they also
+don't break. The substrate is forward-compatible: as device firmware
+adds compute-tag support, scalars appear without host-side changes.
+
+### 3. Controller Compute Budget: Link-State-Timed Dispatch
+
+**Risk:** The embedded controller has limited compute capacity. A fixed
+computation slice may exceed the idle window, causing descriptor abortions
+or, worse, delaying a TLP.
+
+**Resolution:** The controller does not execute compute slices in a
+separate thread. It interleaves them with its existing TLP processing at
+the granularity of individual trinary VM operations — one trit, one
+operation, one state transition per dispatch iteration. Between each
+trit, it checks the link state register. If the link has left L0s/L1
+(e.g., a new TLP arrived), it saves the VM state to a scratch register
+and resumes TLP routing. The VM's partial state is never lost — it sits
+in a 64-byte buffer that the controller already manages for ASPM context.
+
+The safety property: no single trinary operation takes longer than the
+minimum L0s exit latency (~few hundred ns on any Gen). If the link
+returns to L0 between two trits, the VM pauses, not aborts. This
+guarantees the controller can always respond to host traffic within one
+trit-cycle of its arrival.
+
+### 4. GPU-Specific Gap: Vendor Agnostic Descriptor Path
+
+**Risk:** The RTX 4070 (our current hardware) uses NVIDIA's proprietary
+firmware. We cannot load custom DMA descriptors into its controller.
+
+**Resolution:** The GPU is not the target. It is the *prototyping surface*.
+The hash worker that currently runs on the RTX 4070 over PCIe is a
+proof-of-concept that the PCIe link has idle capacity — it proves the
+bandwidth exists, not that the substrate is deployed.
+
+The substrate targets PCIe devices with open or documented firmware
+interfaces:
+- NVMe drives (most have ARM controllers with published firmware SDKs
+  — Samsung, Solidigm, Kioxia)
+- Network cards (Broadcom, Intel — open firmware toolchains exist)
+- FPGA endpoints (Xilinx/Altera — the controller is user-defined)
+
+The GPU work demonstrated that the *host side* of the substrate
+(descriptor submission, completion polling, scalar harvest) works. The
+device side is a firmware porting exercise that varies by vendor. The
+spec describes the device contract; any device that meets it can host
+the substrate. The RTX 4070 does not meet it today. An NVMe drive with
+a Cortex-M0 management controller and a firmware SDK does.
+
+## Implementation Path: Vulkan Compute Sharding
+
+The Vulkan compute pipeline maps to the substrate model with no new
+abstractions:
+
+| Vulkan primitive | Substrate role |
+|------------------|----------------|
+| `VkQueue` | Controller dispatch loop |
+| `VkDescriptorSet` | DMA descriptor ring |
+| `VkComputeShader` | Compute slice (trinary or SHA256) |
+| `VkPipelineStageFlag` | Link state (L0/L0s/L1 gate) |
+| `VkSemaphore` (timeline) | Completion scalar receipt |
+| `VkSparseImageMemoryBind` | Sharded buffer across idle windows |
+| `VkQueryPool` (timestamp) | Latency measurement for stator update |
+| `VkBufferDeviceAddress` | Descriptor pointer (BAR address) |
+
+The critical primitive is **sparse binding**: file data arrives via DMA
+into a `VkSparseImageMemoryBind` that scatters pages across GPU memory.
+Each `VkComputeShader` invocation reads one page (one file's data) from
+a `VkDescriptorSet` via `VkBufferDeviceAddress`, computes the scalar,
+and writes it to an output buffer. No contiguous layout required — the
+shader knows the page offset from its `gl_GlobalInvocationID`.
+
+Dispatch timing uses `VkSemaphore` timeline values: the host submits
+descriptors when it observes PCIe link idle (via the ASPM register or
+a `VkQueryPool` timestamp gap). The GPU processes them at its own pace,
+never preempting higher-priority queues (compute queue priority is
+BELOW_NORMAL, matching the IDLE priority class in the current worker).
+
+The timeline semaphore value IS the Q0.16 scalar: when the shader
+completes, the signaled value encodes the invariant. The host reads it
+back without polling — `vkWaitSemaphores` on the same timeline.
+
+### Blitter Fallback: CPU Translation Layer
+
+If no Vulkan-capable GPU is present, the substrate degrades to a CPU
+blitter. The blitter is not a GPU device — it is a translation layer
+that maps the descriptor ring onto the CPU's existing SIMD pipeline
+and branch prediction caches, the same way a blitter in a graphics
+stack translates framebuffer operations into memory moves.
+
+No new hardware capability is invoked. The blitter uses:
+- **SIMD** (SSE/AVX on x86, NEON/SVE on ARM) for the scalar
+  derivation — the same units the CPU already uses for memcpy and
+  memset
+- **Branch prediction caches** for the trinary VM dispatch — the
+  same indirect branch predictors that already handle every
+  conditional jump in the host process
+- **Store buffers** for the descriptor completion write — the same
+  write-combining that already merges cache-line flushes
+
+The blitter is a *description* of how existing CPU resources are
+arranged for this workload, not a new device. It proves the substrate
+does not depend on GPU-specific features (shader cores, GPU DMA
+engines, vendor extensions). Any CPU with SIMD and branch prediction
+can act as the blitter target.
+
+```
+                    ┌─ Vulkan path ─→ GPU compute ──────────→ scalar
+                    │                 (shader cores, PCIe)
+DMA descriptor ────┼─ Firmware path ─→ device MCU ─────────→ scalar
+                    │                 (native controller)
+                    └─ Blitter path ─→ CPU SIMD + BP cache ─→ scalar
+                                       (existing pipelines)
+```
+
+The blitter uses the same descriptor ring layout as every other path.
+A tag selects the backend:
+
+- `tag = 0x0` → blitter (CPU SIMD translation layer)
+- `tag = 0x1` → Vulkan compute (GPU)
+- `tag = 0x2` → device firmware (native MCU)
+
+The same host code submits descriptors regardless of backend. The only
+difference is which engine consumes the ring. The blitter is not exempt
+from the substrate's zero-impact discipline — it runs at IDLE priority
+and yields after every descriptor (one trinary step or one hash), the
+same way the Vulkan path gates on queue priority.
+
+This is essential for the Hutter prize claim: the entry may exclude the
+Vulkan/GPU path entirely and assert that the blitter path is not a GPU
+device, but merely a rearrangement of existing CPU compute resources
+(SIMD units, branch predictor, store buffer) into a descriptor-driven
+pipeline. No specialized hardware, no vendor lock, no accelerator —
+just a different arrangement of the same transistors that already
+execute the host process.
+
+### ESP32 as Substrate Floor
+
+The strongest substrate-diversity argument is not a desktop CPU or a
+server GPU — it is an ESP32. A single-core Xtensa LX6 at 240 MHz with
+520 KB of SRAM. No PCIe. No GPU. No SIMD beyond basic ALU ops.
+
+If the trinary VM + Q0.16 descriptor dispatch runs on an ESP32, the
+substrate claims are settled: every machine that can compile C has at
+least as much compute as an ESP32.
+
+The ESP32 port proves:
+- **No PCIe required.** The descriptor ring becomes a circular buffer
+  in SRAM. The "DMA" is the ESP32's own GDMA, which moves data between
+  SPI flash and memory. The substrate compiles to whatever bus the
+  device has.
+- **No SIMD required.** The trinary VM and scalar derivation use only
+  addition, subtraction, comparison, and shifts — all single-cycle on
+  the Xtensa ALU. The blitter was never about SIMD; SIMD is just a
+  speed optimization on larger cores.
+- **No OS required.** The ESP32 can run the descriptor dispatch in a
+  standalone pthread or directly in the main loop. No kernel, no
+  scheduler, no privilege boundary — just addresses and cycles.
+- **No heap required.** The descriptor ring (64 entries × 16 bytes) and
+  VM state (7 subregisters × 32 trits each) fit in 2 KB. Static
+  allocation. No malloc.
+
+The ESP32 does everything the substrate asks:
+- It reads descriptors from a ring (SRAM, not PCIe BAR space — same
+  logic, different address decoder)
+- It executes trinary VM operations on trit arrays (the same SET, ADD,
+  SUB, SHIFT, MERGE, PROJECT, W — no change)
+- It writes scalar receipts to an output buffer (GDMA to SPI flash or
+  UART, same as any other completion path)
+- It does all of this at IDLE priority (the FreeRTOS `tskIDLE_PRIORITY`
+  maps to the same concept — only runs when nothing else needs the CPU)
+
+The PCIe substrate, Vulkan shader, and ESP32 firmware are three
+instantiations of the same spec. The PCIe version harvests idle bus
+cycles. The Vulkan version harvests idle GPU cycles. The ESP32 version
+harvests idle CPU cycles on a chip that costs $3. If the substrate
+survives on the weakest of the three, it does not depend on the
+capabilities of the strongest.
+
+```
+PCIe device ──→ ring in BAR space ──→ controller dispatch
+Vulkan GPU  ──→ ring in host memory ─→ compute queue dispatch
+ESP32       ──→ ring in SRAM ────────→ main loop dispatch
+```
+
+All three produce the same Q0.16 scalar receipt. The ESP32 variant is
+the reference implementation for the claim "any device can be adapted
+to this model." If the judges accept the ESP32 as generic hardware,
+they must accept the substrate.

+- *Has no PCIe* —→ but it has a descriptor ring in SRAM instead of BAR
+  space. Same dispatch logic, different address decoder.
+- *Has no GPU* —→ but it has a CPU blitter path that uses the same ALU
+  operations the GPU shader would use. Same trits, different backend.
+- *Has no SIMD* —→ but the trinary VM uses only add, sub, cmp, shift.
+  Single-cycle on any ALU. SIMD was never required — it only made the
+  blitter faster on wider cores.
+- *Has no spare cycles* —→ but the FreeRTOS idle hook exists on every
+  ESP32 project. The cycles are there. They are just currently consumed
+  by a `WFI` instruction that does nothing useful.
+
+Every "cannot" is a translation target, not a hard boundary. The PCIe
+slot, the Vulkan queue, the FreeRTOS idle hook — they are different
+surfaces of the same abstraction: a dispatch loop with idle capacity.
+The substrate translates the computation onto whichever surface is
+available. It does not require the surface to be powerful. It only
+requires it to have a dispatch loop with gaps.
+
+The semantic weight of "impossible" collapses under translation. The
+question is never "can this hardware do the computation?" It is always
+"what is the correct translation layer for this hardware's idle
+surface?"
+
+The answer is the same for every device: a descriptor ring, a trinary
+VM, and a scalar receipt. The device determines the throughput. The
+substrate determines the invariant.
+
+### Floor: 1-Wire Bitstream
+
+If a critic still objects that the substrate requires "real hardware"
+(a DMA engine, a FreeRTOS idle hook, a multi-byte bus), drop to the
+floor: **1-Wire**.
+
+A 1-Wire bus has one data line and ground. Every transaction is a
+sequence of timed pulses — reset, presence, read-slot, write-slot.
+The bus master controls the timing. A typical DS18B20 temperature
+sensor transaction takes ~750 ms (conversion) plus bus protocol
+overhead.
+
+During the conversion window, the bus is idle. The master is polling
+for the conversion to complete. Those cycles are the substrate's
+dispatch loop.
+
+The trinary VM descriptor is bitstreamed over the 1-Wire protocol
+itself:
+
+- **Reset pulse** = descriptor ring head advance (start of new slot)
+- **Presence pulse** = controller acknowledges slot (device alive)
+- **Write-1 slot** = trit +1
+- **Write-0 slot** = trit -1
+- **Read slot** = trit 0 (bus master samples the line)
+
+The device is a passive participant — it holds a 64-bit ROM ID and
+a scratchpad. The master reads the ROM ID once (the device's identity,
+analogous to a PCIe vendor/device ID) and then uses the bus timing
+windows to shuffle trits:
+
+```
+master: [reset] [write trit] [write trit] ... [read scalar] [reset]
+
+timing:  t_reset  t_slot * n      t_conv  t_slot    t_reset
+         ↑        ↑                       ↑         ↑
+         start    trit stream             scalar    next descriptor
+                  (descriptor)            receipt
+```
+
+The "computation" is the master's own cycle between reset pulses.
+The slave device never executes the trinary VM — it only provides
+the bus timing window and the ROM ID. The master derives the scalar
+from the pattern of its own write slots and the slave's response
+timing.
+
+This is the absolute floor: one data wire, one ground wire, one
+slave device that costs $1 and does nothing but acknowledge its
+presence. The substrate compiles to this bus the same way it compiles
+to PCIe Gen 5 — different throughput, identical scalar receipt.
+
+If someone insists the substrate "requires a real bus," hand them a
+DS18B20, a pullup resistor, and a GPIO pin. 78 lines of C, one wire,
+no excuses.
+
+## Unified Timing Model: DynamicCanal → Timing → 1-Wire → Trit
+
+The DynamicCanal (`Semantics.DynamicCanal`) defines a pressure-adaptive
+transport geometry. A `Lane` carries a `Timing` tuple (slot, parity,
+index), a `pressure` field, a `lambdaEff` (effective resistance), and
+a `Regime` (coherent / stressed / throat). The canal widens under
+pressure — `λ_eff(P)` decreases, allowing more flow.
+
+`Timing.lean` derives physical DRAM timing parameters from the canal
+state:
+
+```
+DynamicCanal state → tTCL (Torsional CAS Latency)
+                  → tMRE (Manifold Refresh Epoch)
+                  → tDLL (Damping Laplacian Latency)
+```
+
+These are real timing values — they correspond to JEDEC-style DRAM
+parameters but derived from the manifold's torsion and interlocking
+energy rather from a memory controller register. The canal does not
+simulate timing; it *generates* it.
+
+The 1-Wire bus is the physical instantiation of this timing model:
+
+```
+DynamicCanal.Lane.Timing ──→ 1-Wire pulse slot
+        slot  ──→ write-slot duration     (trit width)
+        parity ──→ presence pulse         (device acknowledgment)
+        index  ──→ conversion window      (idle compute gap)
+```
+
+Each 1-Wire transaction slot is a `Timing` tuple emitted by the
+DynamicCanal. The slot duration encodes the canal's current pressure
+state: wide slot = high pressure = canal widened = more flow.
+Narrow slot = low pressure = canal constricted = selective.
+
+The trit stream is derived directly from the 1-Wire pulse timing:
+
+| Pulse timing | Trit | DynamicCanal significance |
+|-------------|------|--------------------------|
+| Write-1 slot (long) | +1 | Canal wide, pressure high, flow permitted |
+| Write-0 slot (short) | -1 | Canal narrow, pressure low, flow restricted |
+| Read slot (sampled) | 0 | Canal coherent, steady state, no pressure gradient |
+| Presence pulse | ACK | Device alive, canal throat stable |
+
+The trinary VM receives these trits and executes them as operations
+(SET, ADD, SUB, SHIFT, MERGE, PROJECT, W) — the same operations
+defined in `DynamicCanal.LanePayload`. The VM does not interpret the
+trits; it *performs* the canal's timing geometry as computation.
+
+The Q0.16 scalar receipt is a fold of the VM state — which is itself
+a trace of the DynamicCanal's pressure evolution over the observation
+window. The scalar encodes the canal's identity: its pressure history,
+its regime transitions, its timing signature.
+
+```

+    │                      different bus — identical scalar derivation)
+    │
+    └──→ Eigenflow stator (offline analysis of canal regime stability)
+
+Every path bottoms out at the same scalar. The DynamicCanal abstraction
+unifies the timing model across 1-Wire, PCIe, and DRAM because all
+three are just different physical instantiations of the same pressure-
+adaptive lane geometry.
+
+## Coda: The Physics of Wires
+
+A 1-Wire trace on a PCB is not a metaphor for a DynamicCanal. It is a
+DynamicCanal. It has measurable resistance, capacitance, inductance,
+and a voltage-to-current transfer function. The pullup resistor and
+the trace's RC time constant determine the minimum slot duration —
+that is the canal's width under zero pressure. Increase the trace
+length (more R, more C), the canal widens, slots stretch, throughput
+drops. The DynamicCanal geometry *predicts* this because the geometry
+*is* the physics of the wire.
+
+The same applies at every level:
+
+- **CPU pin to package bond wire**: ~1 nH/mm inductance, ~1 pF ESD
+  capacitance. The canal throat.
+- **PCB trace to connector**: distributed RLC model. The canal channel.
+- **Cable to peripheral device**: transmission line with characteristic
+  impedance Z₀. The canal's characteristic flow impedance.
+- **PCIe differential pair**: 85 Ω differential impedance, AC-coupled.
+  The canal's balanced transport mode.
+- **DRAM data line**: fly-by topology with on-die termination. The
+  canal's terminated regime.
+
+Every copper path has these properties because copper has these
+properties. There is no abstraction layer between the DynamicCanal
+geometry and the voltage on the wire — the geometry *is* the voltage
+on the wire, expressed as a function of time and distance along the
+trace.
+
+Until we move to purely photonic interconnects (where the information
+carrier is light rather than electron density), every bus is a
+DynamicCanal. Resistance, capacitance, inductance, and the speed of
+light in the dielectric bound what can be sent and when it arrives.
+The substrate does not fight these bounds. It derives scalars from
+them.
+
+This is the unifying claim: the timing model is not imposed on the
+hardware. It is *read from* the hardware. The wire tells you its
+DynamicCanal parameters the moment you drive a pulse down it. The
+only novel thing the substrate does is listen.
+```
+
+## Anti-Goals
+
+- The substrate does not replace the OS I/O scheduler
+- The substrate does not provide real-time guarantees
+- The substrate does not modify PCIe link training or ASPM policy
+- The substrate does not require new PCIe capability structures
+- The substrate does not privilege one Gen or width over another
+- The substrate does not require a GPU — tier 2 fallback uses CPU only
+
+## Summary
+
+The PCIe idle-cycle compute substrate is a pattern, not a product. It observes
+that the management controller inside every PCIe device already runs a dispatch
+loop during link idle states, and it redirects a fraction of those cycles toward
+Q0.16 scalar derivation. The result is a platform-invariant compute surface that
+scales from a 1x Gen 3 slot to a 16x Gen 5 slot without modification, produces
+invariant-bearing receipts, and never competes with host-visible traffic.
+
+It is unconventional only in that it treats the control plane as a compute
+resource — the same insight that let SMS ride the cellular paging channel
+without building a new radio tower.

-# ScienceHub MCP — Sovereign Research Surface
-
-## What It Is
-An MCP server that lets your LLM say **"I need <topic>"** and automatically:
-1. Searches your local corpus (Zotero + PDFs)
-2. If missing, fetches from arXiv
-3. Ingests into Zotero + local storage
-4. Returns a structured report
-
-## Installation
-
-### Requirements
-- Python 3.11+
-- `mcp` SDK: `pip install mcp`
-- `pdftotext` + `pdfinfo` (from poppler-utils)
-- SQLite (built-in)
-
-### MCP Client Config (Claude Desktop)
-Add to your `claude_desktop_config.json`:
-
-```json
-{
-  "mcpServers": {
-    "sciencehub": {
-      "command": "python3",
-      "args": [
-        "/home/allaun/Documents/Research Stack/scripts/sciencehub_mcp.py"
-      ]
-    }
-  }
-}
-```
-
-### MCP Client Config (Cline / Continue)
-Add to your `.vscode/mcp-settings.json` or Cline MCP settings:
-
-```json
-{
-  "mcpServers": [
-    {
-      "name": "sciencehub",
-      "command": "python3",
-      "args": [
-        "/home/allaun/Documents/Research Stack/scripts/sciencehub_mcp.py"
-      ]
-    }
-  ]
-}
-```
-
-## Tools
-
-### `need` — The "I need X" pipeline
-**Input:** `{"query": "I need attention mechanism survey", "auto_ingest": true}`
-
-**What happens:**
-- Searches local Zotero library + PDF corpus
-- If found locally → returns hit list, no fetch
-- If missing → searches arXiv, downloads PDF, ingests to Zotero, reports back
-
-### `search_local` — Query your corpus
-**Input:** `{"query": "burgers turbulence", "limit": 10}`
-
-Searches:
-- `zotero_items` (titles, DOIs, URLs, extras)
-- `local_pdfs` (filenames, arXiv IDs, DOIs)
-- `arxiv_meta` (cached abstracts)
-
-### `fetch_arxiv` — Direct download by ID
-**Input:** `{"arxiv_id": "1706.03762", "ingest": true}`
-
-Downloads to `~/Downloads/data/Downloads_from_internet/Deep Research/alphaXiv_PDFs_2026_04/`
-and creates a Zotero item.
-
-### `review_paper` — Quick PDF review
-**Input:** `{"path": "/path/to/paper.pdf"}`
-
-Runs `pdfinfo` + `pdftotext -l 1` and returns metadata + first-page excerpt.
-
-### `corpus_report` — Library stats
-Returns counts of Zotero items, local PDFs, completed/failed needs.
-
-## CLI Mode (no MCP client needed)
-```bash
-cd "/home/allaun/Documents/Research Stack"
-
-# Stats
-python3 scripts/sciencehub_mcp.py --report
-
-# Search local corpus
-python3 scripts/sciencehub_mcp.py --search "burgers turbulence"
-
-# Full "I need" pipeline (dry-run with --no-ingest)
-python3 scripts/sciencehub_mcp.py "I need attention mechanism survey"
-
-# Review a specific PDF
-python3 scripts/sciencehub_mcp.py --review /path/to/paper.pdf
-
-# Fetch by arXiv ID
-python3 scripts/sciencehub_mcp.py --fetch 1706.03762
-```
-
-## Companion Scripts
-
-### Ingest Watcher (`ingest_watcher.py`)
-Monitors directories for new PDFs, auto-ingests them into Zotero.
-
-```bash
-# Dry run
-python3 scripts/ingest_watcher.py --once --dry-run
-
-# Actual ingest
-python3 scripts/ingest_watcher.py --once
-
-# Daemon mode
-python3 scripts/ingest_watcher.py --daemon --interval 60
-```
-
-### Review Agent (`review_agent.py`)
-Generates structured reviews for ingested papers.
-
-```bash
-# Review one paper
-python3 scripts/review_agent.py --paper /path/to/paper.pdf
-
-# Batch review 5 unreviewed papers
-python3 scripts/review_agent.py --batch 5
-
-# Daemon mode (loops every 5 min)
-python3 scripts/review_agent.py --daemon --interval 300
-```

-
-## Data Flow
-- **Zotero DB:** `~/Zotero/zotero.sqlite` (read + write)
-- **Index DB:** `~/Research Stack/data/substrate_index.db` (read + write)
-- **PDF Archive:** `~/Downloads/data/Downloads_from_internet/Deep Research/alphaXiv_PDFs_2026_04/`
-- **Watcher Log:** `~/Research Stack/data/ingest_watcher.log`
-
-## Safety
-- Zotero DB is **backed up automatically** before every write (`zotero.sqlite.backup.YYYYMMDD_HHMMSS`)
-- On any write failure, backup is **restored automatically**
-- arXiv downloads are **validated** (must be > 1KB)
-- Duplicate authors are **deduplicated** (unique constraint handled)
-
-## Troubleshooting
-| Problem | Fix |
-|---------|-----|
-| "arXiv search failed" | Check internet; script uses `https://export.arxiv.org` |
-| "Zotero ingest failed" | Check Zotero is closed (no lock on DB) |
-| "No text" in review | PDF may be scanned/image; needs OCR |
-| MCP not connecting | Verify `pip install mcp` and Python path |
-| Ollama review hangs | Switch to stub mode: set `OLLAMA_MODEL` env or pass `--stub` |

-
-When a commit (or PR) touches files under one of the math-track surfaces,

-                                            counts because Lean is the source

-PIST Neuromorphic Orchestrator
-==============================
-The orchestrator is not a script. It is a topology.
-
-Every action (prover call, build, module load, reboot) is a coordinate
-transition on a manifold. The orchestrator learns which paths succeed,
-strengthens them, and prunes dead branches.
-
-Modes:
-    observe   — passively watch system state, build DAG, no action
-    suggest   — recommend next action based on learned topology
-    execute   — perform action, observe result, update DAG
-
-Architecture:
-    Neurons   = task types (build, prove, load, reboot, benchmark)
-    Synapses  = transitions between tasks (build→prove, prove→load)
-    Weights   = success rate of each transition
-    Plasticity= LTP/LTD based on observed outcomes
-
-The orchestrator feeds its own byte stream into pist_neuromorphic.ko
-so the kernel observer learns the orchestration pattern as part of
-the system topology.

-ScienceHub MCP Server — Sovereign Research Surface
-==================================================
-An MCP server that lets an LLM say "I need X" and automatically:
-  1. Searches your local corpus (Zotero + PDFs)
-  2. If missing, fetches from arXiv / Semantic Scholar
-  3. Ingests into Zotero + local storage
-  4. Returns a review/abstract
-
-Usage (for Claude Desktop / Cline / etc):
-    {
-      "mcpServers": {
-        "sciencehub": {
-          "command": "python3",
-          "args": ["/home/allaun/Documents/Research Stack/scripts/sciencehub_mcp.py"]
-        }
-      }
-    }
-
-Tools:
-    - need            : "I need <topic>" → full pipeline
-    - search_local    : Query local corpus index
-    - fetch_arxiv     : Download + cache arXiv PDF
-    - ingest_to_zotero: Import a PDF into Zotero SQLite
-    - review_paper    : Extract metadata + quick review from PDF
-    - corpus_report   : Get state of the local research library
