Official laguna-s-2.1-DFlash-BF16.gguf is on disk but this llama.cpp
rejects it (expected 76 tensors, got 69). Leave the draft unwired so
Laguna loads; keep amdgpu DPM high.
A second request (opencode background agent, pi alongside opencode) no
longer queues behind the first. kv-unified keeps the full 131072-token
context available to either slot instead of splitting it to 65536.

The unit re-applied --https=443 every 5s and fought Mattermost for
that port. llama is served on :10000, managed outside Nix.

OpenCode talks to https://straylight.scylla-hammerhead.ts.net/v1, which is
Tailscale Serve on :443 proxying localhost:11434. Re-apply the serve
config on a timer so cannot leave the API dark.
whisper.cpp large-v3-turbo on :11435 (CPU, OpenAI transcriptions path)
so ASR does not take GTT from llama-server. Flash-Next is the cygnal
IQ4_XS-NGQ4 GGUF (~98 GB, gfx1151), qwen4exp, mmproj pinned; unload
Laguna before loading.
Ornith 1.5 9B is a dense text model, not vision. Replace that role with
prithivMLmods Qwen3-VL-8B Instruct abliterated v2 (mradermacher Q4_K_M)
and pin mmproj-url so router mode actually loads the projector.
Bind 0.0.0.0 and open 11434 on tailscale0 only, so localhost and
other tailnet machines can reach the OpenAI-compatible API. LAN
stays closed. rebuild-nixos deploys committed master, not the
working tree.
Drop the b9828 source pin and take llama.cpp from a refreshed
nixpkgs-unstable (0.4.0), which supports the Laguna and Gemma 4
architectures. Run llama-server in router mode with a preset file:
abliterated Qwen3.6-35B-A3B and Gemma 4 26B-A4B for benchmarking,
Poolside Laguna S 2.1 as the primary coding agent, and Ornith kept for
comparison. At most two models stay resident; idle models unload after
six hours. Add llama-models and llama-unload helper commands.

The TTM default caps GTT at half of RAM (~62 GiB), which is too small for
the 118B-parameter model straylight will serve. Set ttm.pages_limit and
ttm.page_pool_size to 27262976 pages (104 GiB); takes effect on reboot.

Pin herdr v0.9.0 from the upstream flake (nixpkgs-unstable only has
0.7.1) and install it on straylight to host coding-agent terminals.

Host-only 10.99.0.0/24 bridge with no uplink/NAT; firewall drops VM
traffic leaving the bridge so unikernel VMs can reach only the gateway
(mc-proxy). Implements Phase 2 mandatory-mediation networking.

Override the shared mcp.nix sandbox (PrivateDevices) on straylight so the
MCP agent can boot Nanos unikernel VMs under QEMU/KVM and manage TAP
devices for isolated networking.

Add configs/mcp.nix (mcp user UID 850 + mcp-agent service) and open
firewall ports for DNS/mc-proxy/agent/master as straylight takes over
the master + MCIAS + MCNS core role from rift.

All nodes now list 1.1.1.1 and 8.8.8.8 as fallback nameservers after
MCNS. When MCNS is down, internal names (.svc.mcp.metacircular.net)
fail but external DNS (google.com, github.com, etc.) keeps working.
Lesson from 2026-04-03 incident: without fallbacks, MCNS failure
caused total DNS blackout including external services, forcing
Tailscale to be disabled to restore any DNS resolution.

Replace fragile environment.etc.crypttab.text with
boot.initrd.luks.devices for the second SSD, matching
the pattern used for the root drive.
