Both halves of the R-113 conjunction are path-presence tests: GuestSeesMount (intermediary.go:276) and isHostMountpoint (:394) compare field 5 of a mountinfo line and never read field 3, so neither can see that the bind and the raw mount name different devices. Measured BoundUnderParent=TRUE over a namespace that EIOs on every read and write. Reproduced 3/3 on a purpose-built scratch LXC on demo-hp; predicates evaluated by a throwaway probe calling the real localapi code from d4eb259. Three results that change the shape of the fix: - Q7: a bind can die in STEADY STATE with no detach/return cycle. The gate produces no action and nothing is emitted on any channel. A Return-branch fix cannot reach this half, and a devno comparison does not detect it. - Q6/R-117d: AttachDrive's normalize leg already performs the repair, and three call sites already invoke it - including the controller's Return branch before it restarts apps. All defeated by one early return at :235. Unblock the existing path; do not add a new one. - Q1: the device-node change is a CONSEQUENCE, not a precondition. The stale bind pins the dead superblock, forcing the returning device onto a new number. Control test: released, the letter is reused. Not established: the hang case. Venue and probes built, run lost to a site internet outage; the thread-leak hypothesis is not claimed as a result. Teardown of the spike venue is owed - commands in the findings doc; nothing fenced was touched and no hub-side record was created.
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.
