The playbook covered why a run is SLOW. It did not cover the more expensive
failure: a run that COMPLETES, reports plausible numbers, and is wrong about
itself. Seven of those turned up on the Gemma-4 ERP/RP tune between 08-24 and
08-26 and not one raised an error.
New §4, seven landmines plus a pre-launch checklist:
4.1 a cache key must cover the MEANING of the cached thing. The encode
cache missed the impersonation mask; run 2 would have reused run 1's
unmasked encodings and written impersonation_mask_sha256 into its own
manifest while doing it. No error, no count change, normal loss curve.
4.2 validating a VALUE is not validating the PARAMETER. warmup_ratio was
in range and deleted from transformers 5. Build kwargs as data and
diff the NAMES against the installed signature -- you cannot check the
argument list of a call you have already made.
4.3 record what the run RESOLVED to, never what it requested. Run 1
recorded no attention backend, so an MFU panel profiled the serving
seat under sdpa and recommended adopting flex_attention for a run that
was already using it.
4.4 never train from a dirty tree; harness_commit will name a commit that
does not describe the run. Annotate afterwards, never edit the shipped
artifact -- and state what is NOT wrong, or the note casts doubt on
every field it omits.
4.5 a watchdog whose pgrep pattern appears in its own argv can only ever
return "alive". The inert-gate shape in a liveness check.
4.6 an instrument nobody runs is not an instrument. Mutation-check any
test guarding a property that fails silently.
4.7 fix a stale measurement at the source. "~4.3 HOURS to rebuild the
encode cache" (really 145.5 s) was copied into a new launcher by the
same person who had just measured the real number.
4.8 the pre-launch honesty checklist, ten minutes.
Also:
- Header and framing widened. The file is now a training playbook with a
throughput half and an integrity half; the filename stays for inbound links.
- Sections 4-7 renumbered to 5-8. External refs are all to §1.1 and §3.4 and
are unaffected.
- Four rows added to the superseded-claims table, including the kernel table /
68% quadratic / 8.6% MFU set, which describe the serving seat rather than
the training run.
- gemma4-erp-tune-sizing.md §6 carries a correction banner with the explicit
falls/survives split, because that is the doc someone actually reads before
a run.
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.
