The three rungs now sit on the same unwrapped corpus, seed, step count and token count, so carrier size is the only variable. Held-out loss reads 3.329 at 0.6B, 3.018 at 1.7B and 2.814 at 4B -- deltas of 0.311 and then 0.204, diminishing but still real. 4B answers the question the rung existed for. Scene-level continuity holds: on the office-kitchen prompt it produces a named character with motivated dialogue, a spatial layout the narrator navigates, and a physical description, all in one passage, where 1.7B wrote pretty but eventless prose about opening doors and looking at stars. On the letter prompt it opens the letter, promises to quote it, and then quotes it across a paragraph break. Voice saturation is also the best of any rung: curly quotes 17 of 18 against its own base arm's 1 of 18, and collapse 0 of 18 against 4 of 18. Two findings that change earlier conclusions. 4B is the first rung to overfit inside one epoch. Its series runs 2.832, 2.816, 2.814, 2.820, 2.824, 2.825, 2.825 -- a minimum around step 75 and then a turn. Both smaller rungs plateaued without turning, so the optimal epoch count shrinks as the carrier grows and my earlier "one epoch is right for this corpus" holds only for the small end. The consequence is operational: the adapter directory holds the end-of-run weights at 2.825 rather than the step-75 best at 2.814, and it exists as a recoverable checkpoint only because save_steps was set. The voice arms were cut from the end-of-run adapter, so the booth understates 4B slightly. The tone-override also appears to close. On the operator's frame prompt asking for a wonderful story, 1.7B held the frame on every seed but killed the animals on two of four; 4B kept them alive on both seeds, and one of them had the narrator doubt the story he was told and supply a parallel childhood memory to explain the doubt. That is a narrator with an interior position on the tale. Two samples per arm, so directionally right rather than established.
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.
