§3.11. Three consecutive "what about X as a base?" questions in one session,
each answerable in minutes, none of which had been asked before a 7-hour
training window was committed. Writing the check down so it runs first.
1. does it fit for TRAINING - BF16 weights against the real measured peak,
not the weight figure (Gemma-4 is 48.1 GiB of weights and peaks at
79.7 GiB at mb2/seq-16k). Model-line names lie: "Mistral Small 4" is 119 B,
238 GB in BF16, more than both cards combined. QLoRA is not an escape
hatch for MoE - bitsandbytes walks nn.Linear and fused 3-D experts are not
that.
2. if MoE - does the serving engine implement get_expert_mapping. Zero means
LoRA cannot be served at all. gemma4*.py -> 0; deepseek_v2, mixtral,
glm4_moe, ernie45_moe -> present.
3. does the model class support LoRA - and GREP THE CLASS, NOT THE FILE.
Point 3 has teeth and I nearly got it wrong twice in one turn. mistral.py greps
as SupportsLoRA=0 and is fully LoRA-capable via LlamaForCausalLM.
mistral_large_3.py greps as 0 for both and inherits get_expert_mapping from
DeepseekV3ForCausalLM. Capability is inherited; a file-level grep misses it and
only MRO resolution answers it. Same class of error as asserting a substring
instead of an effective value.
Worked results recorded for the three candidates evaluated:
Gemma-4 26B-A4B fits, no expert mapping -> trainable, MERGE-ONLY
Mistral Small 4 119B 238 GB, has mapping -> servable, NOT trainable here
Ministral 3 14B ~28 GB, dense, inherited -> passes all three
Adds a fourth glance at architecture shape, since it predicts how much of this
playbook applies at all: uniform head_dim <= 128 with no sliding window keeps
both flash and cuDNN reachable and makes §3.1/§3.3 moot, while mixed head dims
plus a sliding window is exactly what forces dense O(n^2) attention onto
Ampere-generation kernels for 65% of the step.
eshpfi-management
Infrastructure management workspace for the PFI fleet (plus the ESH home-lab host). Tracks server state, canonical Docker Compose stacks, per-host configs, and the tooling that moves them around.
See CLAUDE.md for the full set of conventions and the rules Claude Code sessions follow when working here.

Common tasks
Refresh one host's snapshot:
scripts/refresh-server-info.sh ana-docker
Refresh all hosts:
scripts/refresh-server-info.sh all
Refresh all Proxmox nodes (separate flow — captures VM/LXC/backup-coverage):
scripts/refresh-proxmox-info.sh all
Add a new host:
scripts/add-host.sh <name> <ip-or-user@ip>
scripts/refresh-server-info.sh <name>
Validate discovery (without hitting the network):
scripts/refresh-server-info.sh --validate-only all
Push a stack to a host (with diff + confirm):
scripts/deploy-stack.sh <host> <stack>
Pull every server's compose/conf trees into stacks-mirror/ (not committed — see .gitignore):
scripts/sync-stacks.sh all
Bootstrap a new fleet repo from this one:
scripts/fork-fleet.sh ~/development/<other-fleet>-management
# optional: override the fleet-name baked into the skeleton CLAUDE.md / README
scripts/fork-fleet.sh ~/development/<dest> <fleet-name>
Mirrors the reusable tooling (everything under scripts/, the
generic playbook templates, .gitignore, conventions section of
CLAUDE.md) into the destination dir, strips fleet-specific content
(servers/, stacks/, configs/, fleet-named playbooks
(deploy-*, decouple-*), docs/orientation.md, docs/runbooks/,
docs/pfi/, STATUS.md, host-pinned helper scripts), regenerates
skeleton CLAUDE.md / README.md / STATUS.md with the new fleet
name, and initializes a fresh git history with one "Initial commit".
The script does not create a gitea remote or push — namespace +
repo name are an explicit manual step. The "next steps" output prints
the exact tea repo create + git remote add + git push commands
to wire it up when ready.
Backup pipeline
Backups are driven by per-host resticprofile configs under configs/restic/<host>/, scheduled via systemd timers on each host:
- Writes: each host backs up to its site-local rest-server (
rest-server-anaorrest-server-nh3), over HTTP basic-auth. - Authentication: shared
.htpasswdfile on both rest-servers, one entry per host; credentials stored in/etc/restic/restic.envon each client host. - Encryption: per-host client-side passphrase in
/etc/restic/password(unique per repo; losing it = losing that host's backups). - Visibility: Backrest (
http://10.250.50.70:9898) shows every repo for browsing/restore. - Schedule: backup at 01:00 daily,
forgetat 03:00 daily, weeklycheck --read-data-subset 10%on Sundays. - Prune: manual ceremony (rest-server runs with
--append-only, which blocks destructive prune ops). - Off-site: cross-site rsync between the two rest-server data dirs is planned (not yet implemented).
Coverage status (as of 2026-04-29)
Goal: every Docker host + configs + every database covered, not just VM images.
| Layer | State |
|---|---|
| VM-level (Proxmox vzdump) | ✅ All running guests covered across pfi-pve / nh3-pve / esh-pve-nas; esh-pve has VMID 108 uncovered |
| ana-docker restic (host files + DBs) | ✅ configs/restic/ana-docker/ with pre-backup hooks for synapse / seafile / vaultwarden-pg / gitea (native dump) / openwebui |
| ana-ml2 restic | ✅ configs/restic/ana-ml2/ — bare-metal host files (no DB hooks needed) |
| nh3-docker restic | ✅ Light — no DB hooks needed |
| esh-docker-vm restic | ✅ With DB hooks for paperless-postgres (external), home-assistant + pgadmin + uptime-kuma (host-side sqlite3), calibre-web-automated (in-container sqlite3) |
| vm-esh-nas restic | ✅ Light — NFS mounts explicitly excluded |
| nh3-dev (workstation) restic | ✅ /home/lkraven + /etc with language-toolchain and build-output excludes |
| irv-ml1 restic | ✅ Cross-site to rest-server-nh3 via WireGuard |
| esh-vm-db restic | ✅ With pg_dumpall + mongodump pre-backup hooks |
| Cross-site redundancy | ✅ ana-nas → nh3-nas rsync at 04:00 daily; nh3-nas → ana-nas at 05:00 daily (configs/rsync/) |
| Prune ceremony | ✅ Quarterly manual ritual documented in docs/runbooks/nh3-prune-ritual.md (DSM-mediated --append-only toggle) |
| offen/docker-volume-backup sidecars on esh-docker-vm | ❌ Remove once restic proves itself (~1 week of clean runs) |
Authoritative vs. mirror
- Authoritative: files on each server under
/opt/docker/compose/<stack>/and/opt/docker/conf/<stack>/. - This workspace: source-of-truth copies under
stacks/<name>/(hand-curated), and a gitignored mirror understacks-mirror/pulled bysync-stacks.sh.
Edit in stacks/, push with deploy-stack.sh. Never commit stacks-mirror/ — it can contain embedded plaintext secrets from upstream compose files that haven't been audited yet.
