Part 4 (ships): `david` — a prospective customer with hosts=0, host_deletions=0, reports=0 — e-mailed an expected_dbdump_missed ERROR at 03:00 UTC three mornings running. The existing down-skip could never cover it: it reads the staleness checker's state, which is seeded from a query over the `reports` table, so a customer that never reported has no state at all and GetState() returns "" rather than "down". store.HasEverBoundHost (hosts row OR host_deletions tombstone) is consulted once per customer at the top of the deadline loop. The discriminator is "was a host EVER bound", never "has a report arrived" — a box installed and never heard from is a real fault and keeps alarming. Fail-OPEN on a read error. Red-proof observed: removing the guard fails with `got [expected_dbdump_missed]`, verbatim the event david sent. Parts 0-3 (spike, NO production code for R-193/R-192): audits/SPIKE-offsite-credential-recovery-2026-08-04.md establishes that the one-shot provider password is the RECOVERABLE secret and the restic repository password is the irreplaceable one — and that a guest rebuild mints a fresh one, orphaning the previous off-site history. Measured without touching a box, by comparing host_escrow.restic_pw_sha256 against host_escrow_superseded: BOTH demo boxes changed (demo-hp 15 snapshots / 40.9 MB, demo-felhom 36 snapshots / 1.14 GB). demo-felhom's "lucky" 76-second recovery restored delivery and not the repository, silently, for 13h. ReissueCredentials does NOT rotate the restic password (R-39's record and two hub comments are wrong -> R-196); candidate (b) is not implementable against a zero-knowledge escrow; candidate (a) already exists as F3 and is wired to the wrong event. Ends in ranked options and an unanswered question for the operator. R-195 SHIPPED; R-196 + R-197 filed; R-192 + R-193 updated, neither closed.
Felhom — Documentation
Felhom is a managed home-server service for Hungarian households, built on a three-component model over Proxmox:
- Hub — operator backend on k3s (
hub.felhom.eu). Repo:felhom.eu/hub/. - Host agent — one per Proxmox host; operator-tier; owns all Proxmox interaction. Repo:
felhom-agent/. - In-guest controller — one per customer LXC; Docker-only; manages the customer's apps. Repo:
felhom-controller/.
This directory is the central, code-verified documentation home for all three components plus the platform and the security-audit record.

Conventions
- Code-verified, not memory-derived. Architectural claims here are checked against the actual current source; if a claim can't be verified it is omitted and flagged, not guessed.
- Per-repo operational working files (
CLAUDE.md,CONTEXT.md,CHANGELOG.md,BUGHUNT.md,REPORT.md,TASK.md) live in their own repos — they are operational, not published docs. - Authoritative versions at last refresh: controller v0.59.0, agent v0.29.1, hub v0.11.0.
