Replace the TODO(lean-port) sorry with a complete proof of the
projectionOrdering theorem: for positive SourceValue pairs s1 < s2
with s2 ≤ maxExpected, projectToCoding preserves strict ordering
of the Q0_64 values.
The proof uses Nat-only arithmetic (no Float) and handles two cases:
- a2 < d: both values fit in Q0_64 range, ordering follows from
monotonicity of integer division
- a2 = d: a2*s/d = s clamped to q0_64MaxRaw; a1*s/d < q0_64MaxRaw
via the key inequality (d-1)*s < (s-1)*d

This squashes all local history (768 commits) onto the scrubbed PR #90
baseline. Individual commits were lost during filter-repo corruption;
the working tree content is preserved intact.

- Bootstrapped microvm-racknerd node on its live Tailscale IP 100.80.39.40.
- Connected racknerd to the central QFox cluster.
- Assigned racknerd to its own vps zone with 1G capacity.
- Made garage-cluster-init.sh robust and idempotent.
- Updated comments and topology mappings.

- Vectorized create_yuv420_frame when numpy is available to eliminate the 500k-iteration scalar Python loop.
- Pre-filled memoryview slice buffers in the fallback path.
- Updated 4-Infrastructure/AGENTS.md to document the optimization.

Synthesized and placed-and-routed the UART beacon design on Tang Nano 9K with physical reset bypassed (rst_n_internal = 1'b1). Programmed the SRAM using openFPGALoader (CRC check: Success). Verified the physical UART blockage due to BL702 bridge firmware limitations via local probe, confirming the virtual serial route (virtual://q16-pty) as the active verification path. Updated scoped AGENTS.md files with the latest hardware status and Lean build baselines.

- Revert builder image in embedded_surface Dockerfile to rust:bookworm for glibc compatibility with bookworm-slim runner.
- Replace racknerd-surface.json Git LFS pointer with the actual retrieved JSON config to resolve parse errors.
- Separated and imported regenerated docker images for stubs and credential-server on all cluster nodes.
- Fixed Ingress resources and middleware to target the correct authentik-server service name.
- Rewrote verification script checks to handle iptables-based ports and relative redirects robustly.
- Updated nixos-laptop IP in node topology documentation.

Full Observe→Decide→Act→Emit loop for the restic + Garage + rclone stack:
- storage_agent.py: probes Garage health, restic snapshot count and dedup
ratio (Q16_16), backup log staleness, cold-copy drift; triggers corrective
actions (snap, cold-copy, verify, forget, offload, garage restart) based
on Q16_16 threshold comparisons. Emits hash-chained receipts to both a
local JSONL log (~/.cache/storage-agent.jsonl) and
s3://research-stack/agent-receipts/ in Garage.
- storage-agent.service / storage-agent.timer: systemd units installed
system-wide; timer fires every 15 min (RandomizedDelaySec=60). Includes
PATH=/home/allaun/.local/bin:... so aws cli and restic are resolved.
- .git/hooks/post-commit updated: agent runs (--once) in the background
after each restic snap, so post-commit state is always observed.
- 4-Infrastructure/AGENTS.md: full documentation of agent contract,
receipt schema, trigger table, log paths, and usage examples.
Shim boundary: zero logic — pure subprocess calls to existing CLI tools.
No Float, no new dependencies. py_compile and live dry-run verified.
