Mitchell-JohnsonandClaude Opus 5 d8bf5df89f Fullscreen on Safari, and a fallback where there is none
Safari on a Mac wants the webkit prefix; Safari on iOS has no fullscreen for an ordinary
element at all, only for a <video>, so requestFullscreen was simply undefined and the tab
threw. It now uses whichever spelling the browser has, and where there is none the frame
fills the viewport in-page instead — the same result minus the browser's own chrome — with
a Done button and Escape to come back. The button reads Expand rather than Fullscreen when
that is what it will do.

Mitchell-JohnsonandClaude Opus 5 e64b0a1727 PLAN: the KVM tab is per machine

Mitchell-JohnsonandClaude Opus 5 f3441ae718 The KVM tab is per machine, and follows the machine switcher
It was a hub-side list you pointed at machines, which had it backwards. A machine has one
KVM; switch to grid and you get grid's. The address is still kept on the hub rather than on
the machine, because a KVM earns its keep exactly when that machine is down and cannot
answer for itself — so the tab reaches the device either way. Adding a second KVM for a
machine replaces the first rather than sitting beside it.

The tab is no longer hub-only and now sits beside Machines in the rail.

Mitchell-JohnsonandClaude Opus 5 fd88c4ff78 A KVM tab: paste an address, get the device's own page
Ham Lab proxies each KVM from its own origin, which is what makes the simple version
possible. A KVM that speaks only plain HTTP would otherwise be blocked outright as mixed
content in a TLS console; served from here it loads, it is behind this login rather than a
second one, and the iframe is same-origin.

Nothing in it knows anything about any particular device. The prefix /kvm/<id>/ is only the
entry point — a device UI asks for its assets by absolute path, which no prefix can rewrite
away, so any request Ham Lab does not serve itself is routed back to whichever KVM the
asking page belongs to, worked out from the Referer and from a cookie when there is no
Referer, as on a WebSocket upgrade. Ham Lab's own routes always match first, so a device can
never shadow the console, and the fallback is gated on a live session.

The list is hub-side on purpose: a KVM earns its keep when the machine is down, which is
when that machine's own Ham Lab cannot answer.

On the keyboard, a page cannot forward keys into an iframe and does not need to — one with
focus receives them directly. Fullscreen plus navigator.keyboard.lock() is what takes
Escape, Tab and Ctrl-W back from the browser; that is Chromium-only and the tab says so
rather than pretending otherwise.

Mitchell-JohnsonandClaude Opus 5 daf33a44b2 The datasets table is a snapshot explorer, and snapshots can be deleted
Renamed Datasets to Snapshots and turned the columns around to match: how many each
dataset has and what they cost come first, the dataset's own size after. Opening one lists
its snapshots with when it was taken, when it expires — read from the TTL in its own name,
so no server call is needed — its size, and a Delete button. Deleting takes the same-named
snapshot on descendant datasets too, which is how a recursive schedule made it, and says so
before it does anything.

Dropped "What would it delete?" from the schedule cards, and the endpoint behind it. Run
now says plainly that expired snapshots go at the same time, which is the whole of what the
preview was telling anyone.

2026-09-24 13:12:17 -07:00
Mitchell-JohnsonandClaude Opus 5 09b7558d44 Snapshot schedules are real cron jobs, written and owned by Ham Lab
A schedule is now a line in /etc/cron.d/hamlab-zfs, which Ham Lab owns and rewrites whole
whenever the schedules change; the line calls `hamlab zfs-snapshot <id>` as the account Ham
Lab runs as, reaching zfs through sudo exactly as the daemon does. The daemon's own ticker
is gone. Snapshots are backup-shaped and should not stop because a web console is down,
being upgraded, or uninstalled — and a cron line is greppable by anyone looking at the
machine the normal way, which a schedule hidden inside a daemon is not.

A cron expression is now the single description of when a schedule fires: the four common
shapes render to one, a custom schedule states it outright, and the next run is read back
with the same evaluator the Jobs tab uses on everyone else's lines. So the page, the file
and the prediction cannot disagree.

Schedules gain a custom cron expression and an optional snapshot name prefix. What a run
did moves out of the policy into zfs-runs/<id>.json beside the config, because the cron job
is a separate process and must never write state.json behind the daemon's back.

The detected external job can be adopted: its schedule, retention and dataset are read out
of the cron line into a new Ham Lab schedule, ready to check rather than retype.

Mitchell-JohnsonandClaude Opus 5 7d0ec5e018 ZFS gets its own tab, with scheduled snapshots and a retention period
Pools, datasets and snapshots move out of Disks — Disks is the hardware, this is the
filesystem on top of it. New: snapshot schedules, hourly to monthly, with a retention
period and a floor that keeps the newest few whatever their age.

The naming is zfSnap's, deliberately. grid has run zfSnap from root cron since before this
repo existed and it works, so rather than invent a second convention this writes and reads
exactly what zfSnap does: 2026-09-24_02.30.01--6w, with the retention in the name. Ham Lab
can therefore show and expire the snapshots zfSnap already took, the two cannot disagree
about what a snapshot is, and changing a schedule never re-dates old ones — each carries
the rule it was taken under. An existing cron job is detected and shown on the page, with a
warning if a Ham Lab schedule is running as well.

Nothing is destroyed unseen. Every schedule answers what it would delete, with the list,
before Run now touches anything, and only names that parse as a stamp and a TTL are ever
candidates. A snapshot taken by hand is invisible to it.

Disks: one row per physical drive with its model, size, temperature and IO, and a usage
bar built from the filesystems the sampler can attribute to it. Attribution is new — a
mount's source device is resolved through sysfs to the drive behind it, following one
layer of device-mapper or md and folding NVMe namespaces the way the sampler does. A pool
member gets no usage bar, because one drive's share of a raidz pool is not a real number.

Net: every interface that is up is listed and tappable, defaulting to the one that has
actually carried traffic rather than whichever the kernel listed first.

a dashboard could silently reset the sampling rate for the whole machine, overriding the
fleet refresh rate set in Settings. The sampler now has one source: `refreshMs` in the UI
prefs, which the hub fans out, remembered per machine as `sampler_ms`.
- **ZFS tab, with scheduled snapshots** — **shipped 2026-09-24** (`internal/storage/snapshots.go`,
`internal/api/zfs.go`, `ZFS.tsx`). Pools, datasets and snapshots moved out of Disks —
Disks is the hardware, ZFS is the filesystem on top of it — and the tab gained what it was
split out for: **snapshot schedules**. Hourly, daily, weekly or monthly, per dataset,
optionally recursive, with a **retention period** and a floor that keeps the newest few
whatever their age. A missed window (the machine was off) runs once on return rather than
being skipped.
**The naming is zfSnap's, deliberately.** `grid` has run zfSnap v1.11.1 from root cron at
02:30 with a 6-week TTL since before this repo existed, and it works. So rather than
invent a second convention for two tools to disagree over, this writes and reads exactly
what zfSnap does — `tank@2026-09-24_02.30.01--6w`, **retention encoded in the name**. Three
consequences: Ham Lab shows and expires the snapshots zfSnap already took; the two can run
side by side without fighting, since both only remove what has passed the expiry written
into its own name; and changing a schedule never re-dates old snapshots, because each
carries the rule it was taken under. The page **detects the existing cron job**
(zfSnap, zfs-auto-snapshot, sanoid, or a bare `zfs snapshot`) and says so, warning if a Ham
Lab schedule is running as well.
**Nothing is destroyed unseen.** Only names that parse as a stamp and a TTL are ever
candidates for expiry, so a snapshot taken by hand is invisible to a schedule; Run now
says that expired snapshots go with it; and a snapshot deleted by hand is confirmed first
and needs its full name echoed back by the caller. (A "what would it delete?" preview
shipped and was removed the same day as redundant — Mitchell's call.)
The datasets table is a **snapshot explorer**: each dataset shows how many snapshots it has
and what they cost, and opens into the snapshots themselves — when each was taken, **when
it expires** (read from the TTL in its own name, so no server call), its size, and Delete.
Deleting takes the same-named snapshot on descendant datasets too, which is how a recursive
schedule made it.
**A schedule is a real cron job** (2026-09-24, Mitchell's call after the first cut ran it
from a ticker inside the daemon). Ham Lab writes `/etc/cron.d/hamlab-zfs`, owns it, and
rewrites it whole on every change; each line calls `hamlab zfs-snapshot <id>` as the
account Ham Lab runs as, reaching zfs through sudo as the daemon does. Snapshots are
backup-shaped and must not stop because a console is down, upgrading, or uninstalled — and
a cron line is greppable by anyone looking at the machine the normal way. **A cron
expression is the single description of when a schedule fires**: the four common shapes
render to one, `custom` states one outright, and the next run is read back with the same
evaluator the Jobs tab uses on everyone else's lines, so the page, the file and the
prediction cannot disagree. A run's outcome is written to `zfs-runs/<id>.json` beside the
config, never to `state.json`, because the cron job is a separate process and the daemon
would clobber it. An existing external job can be **adopted** — its schedule, retention
and dataset read out of the cron line into a new Ham Lab schedule.
**zfSnap is retired on `grid`** as of that day: Ham Lab now takes the nightly `tank`
snapshot, the package is purged and the old cron line is gone, with the 515 snapshots it
had taken left untouched and fully readable here — which is what adopting its naming
bought. See `hamlet/docs/hosts.md`.
- **KVM tab** — **shipped 2026-09-24** (`internal/api/kvm.go`, `KVM.tsx`, `config.KVM`).
Paste a device's address; its own web page appears in the tab. **Nothing in it knows
anything about any particular KVM** — the first device here is a Sipeed NanoKVM on `grid`
at `10.0.0.217`, but none of that is in the code.
**Why it proxies rather than framing the device directly.** Ham Lab is served over TLS and
a KVM usually is not, so a bare `http://…` iframe is blocked as mixed content before it
loads. Serving the device from Ham Lab's own origin (`/kvm/<id>/…`) fixes that, puts it
behind **Ham Lab's** login rather than a second one, and makes the iframe same-origin.
**The general problem, and the answer.** A device UI asks for its assets by absolute path
— `/assets/app.js`, `/api/whatever` — which no path prefix can rewrite away, and rewriting
bodies per device would not be general. So the prefix is only the entry point: any request
Ham Lab does not serve itself is routed to whichever KVM the asking page belongs to, read
from the **Referer**, falling back to a **cookie** when there is none (a WebSocket upgrade).
Ham Lab's own routes always match first, so a device can never shadow the console, and the
fallback is gated on a live session. The device never receives Ham Lab's session cookie,
and its `X-Frame-Options`/CSP/HSTS are dropped on the way out since Ham Lab is the origin
now. Redirects to the device's root are rewritten back through the prefix.
**One catch found in testing:** Ham Lab's own `frame-ancestors 'none'` forbids framing even
from the same origin, so `/kvm/` paths send `'self'` instead. Without that the iframe was
refused before it loaded.
**The keyboard** needs less than it sounds: a page cannot forward keys into an iframe and
does not need to, since one with focus receives them directly. Fullscreen plus
`navigator.keyboard.lock()` is what takes Escape, Tab and Ctrl-W back from the browser;
that is Chromium-only, and the tab says which version you are getting rather than
pretending.
**One KVM per machine, and the tab follows the machine switcher** (corrected the same day:
the first cut was a hub-side list you pointed at machines, which had it backwards). Switch
to `grid` and you get grid's; adding a second for a machine replaces the first. The
addresses are still kept **on the hub** rather than on each machine, because a KVM earns
its keep exactly when the machine is down and its own Ham Lab cannot answer — the hub
proxies the device either way — and a KVM need not belong to a machine Ham Lab manages at
all. Not done: holding the device's own login on the hub, so its page does not ask for a
second password.

pulls it. Ham Lab has no equivalent. Decide whether to build it or to drop it — most
stacks here have no row in that table anyway, so dropping it may be honest.
- **Scheduled image updates.** Ham Lab checks for new images only when asked (a registry
request Docker Hub counts) and never updates by itself. If anything relies on Dockhand
updating on a schedule, that must move here or be dropped on purpose.
- **Webhooks / per-host environments**, if either is in use — inventory before deciding.
- **Deploying from a host path without an orchestrator container.** Ham Lab already runs
compose inside `dockhand` because that is how the stacks were deployed; once they move
to a neutral home the "via" path is unused for them, but a stack deployed to `grid` or
the Mac still goes over `tcp://<node>:2375` from the hub. Decide whether Ham Lab should
instead ask the node's own Ham Lab to deploy locally, which would end the `*:2375`
exposure (its own item in `docs/pending.md`).

2026-09-24 to take in Docker tab polish and feature work, on the same reasoning as the
Files item: it is one tab, and the gaps that block retiring the old tool and the things
that would simply make it better are the same body of work. The *homelab* half —
migrating every stack off Dockhand's data dir, then removing the container — is `hamlet`'s
`docs/pending.md` → "Retire Dockhand; Ham Lab becomes the orchestrator", agreed
2026-09-20. This entry is the *app* half.
Where it stands: Stacks already creates, edits, deploys, updates, restarts, stops, downs
and deletes stacks on every machine, and Containers does start/stop/restart, logs that
follow, inspect, and the images/volumes/networks tables. So this is not a rewrite.
- **What Dockhand still does that Ham Lab does not.**
- *Git-sourced stacks.* Dockhand's `stack_sources` table points a stack at a repo and
pulls it. Ham Lab has no equivalent. Decide whether to build it or drop it — most
stacks here have no row in that table anyway, so dropping it may be the honest answer.
- *Scheduled image updates.* Ham Lab checks for new images only when asked, since each
check is a registry request Docker Hub counts, and never updates by itself. If
anything relies on Dockhand updating on a schedule, that must move here or be dropped
on purpose. Note the Jobs tab and the ZFS schedules already show the shape this would
take: a cron line Ham Lab owns, not a ticker in the daemon.
- *Webhooks and per-host environments*, if either is in use. Inventory before deciding.
- **Known gaps in the tab itself**, worth closing whether or not Dockhand goes:
- *Removing networks* — volumes and images can be pruned and removed, networks cannot.
- *Container detail is thin next to the stack view.* No per-container resource limits,
restart-policy editing, or exec-into-container from the tab (the Terminal tab is the
workaround). Decide which of these belong here at all.
- *Logs are polled with `--since` rather than followed over a held connection.* That was
deliberate and works, but a long tail is choppier than the Services tab's live tail,
which does hold a connection. Worth reconciling the two.
- *Image update checks are remembered six hours and asked for per stack*, so there is no
one view of "what is out of date across the fleet".
- **The `*:2375` question, which this is the moment to settle.** Ham Lab runs compose
inside `dockhand` because that is how the stacks were deployed; once they move to a
neutral home that path is unused for them, but a stack deployed to `grid` or the Mac
still goes over `tcp://<node>:2375` from the hub. Decide whether the hub should instead
ask the node's own Ham Lab to deploy locally, which would end the unauthenticated
Docker socket exposure — its own item in `docs/pending.md`, currently filed under
"decided, no action", and this is the change that would make closing it free.
- *Not app work, but the trigger:* nothing above blocks starting the migration except the
inventory. Do that first.
- **Rename the Space tab** — asked for 2026-09-23, not started. "Space" is vague; the tab
is WizTree for a disk or pool. Candidates: **Usage**, **Disk Usage**, **Storage**. Note
`Disks` already exists and `Storage` would muddle with it, so Usage is probably the one.
The rename touches the rail label, the `View` id, the hash route (`#/<machine>/space`,
which people may have bookmarked — decide whether to keep `space` as the id and change
only the label), the footer's page name and `Space.tsx`'s own strings.
- **ZFS gets its own tab, under Disks** — asked for 2026-09-23, not started. Today ZFS is a
section inside `Disks.tsx`: pools with health, capacity, fragmentation, scrub controls, a
dataset tree and per-dataset snapshot lists with "Snapshot now". Moving it out makes room
for what is actually wanted: **scheduled snapshots with a retention policy**, configured
from the console rather than by hand. What exists to build on — `grid` runs `zfSnap`
nightly at 02:30 from root cron with 6-week expiry (`zfsnap-cron-6w-daily.sh`, predates
this repo), and Ham Lab's Cron tab can already read, write and run root crontabs, so the
job can be managed rather than reinvented. Decide: does Ham Lab drive `zfSnap`/`zfs-auto-
snapshot` if present, or write and own its own timer? Per-dataset policies or one for the
pool? And it must show what a retention rule *will* delete before it runs.
- **Rename Cron to something generic** — asked for 2026-09-23, not started. Mitchell's
reasoning: the Services tab is systemd but "Services" is the right generic name for it,
so the scheduling tab should be named for the job it does, not the tool. **Scheduled** or
**Jobs**. The tab already covers more than cron — `/etc/crontab`, `/etc/cron.d`, user
crontabs, `run-parts` directories *and* systemd timers — so the generic name is the
honest one. Same rename surface as the Space tab: rail label, `View` id, hash route,
footer name.
- **A Virtualization tab** — asked for 2026-09-23, not started, and **large**. Run and

// IP-KVMs: a device's own web page, shown inside Ham Lab.
//
// The whole difficulty is that Ham Lab is served over TLS and a KVM usually is not, so a
// browser refuses to put the device's page in an iframe — mixed content, blocked before
// anything loads. The fix is to serve the device from Ham Lab's own origin, which also
// means it inherits Ham Lab's login instead of needing a second one, and makes the iframe
// same-origin.
//
// Proxying an arbitrary web app under a path prefix is the hard part, and nothing here
// knows anything about any particular device. A device UI asks for its assets by absolute
// path — "/assets/app.js", "/api/whatever" — which a prefix cannot rewrite away. So the
// prefix is only the entry point: any request Ham Lab does not serve itself is routed to
// whichever KVM the asking page belongs to, worked out from the Referer, and from a cookie
// when there is no Referer (a WebSocket upgrade, say). Ham Lab's own routes always win, so
// a device can never shadow the console.

// Scheduled snapshots with a retention period: take a snapshot of a dataset on a schedule,

// **The naming is zfSnap's, deliberately.** grid has run zfSnap v1.11.1 from root cron since

// Two rules make this safe to run unattended. Only a snapshot whose name parses as a stamp
// and a TTL is ever a candidate — anything taken by hand or named anything else is invisible
// to it. And every policy can be asked what it would delete, before it deletes anything.
