Mitchell-JohnsonandClaude Opus 5 32fdbf169a Fix the blank VPN tab, and stop one page taking the console with it 
On a machine with wireguard-tools installed but no tunnel up — core, which is
the machine the console opens on — the tunnel list was a nil slice, which is
null in JSON, and the page took its length. That throws, React unmounts the
whole tree, and what is left is a blank window with nothing to go on.

Two fixes, because either alone leaves the failure possible. The parse returns
an empty list rather than nil, with a test that pins the marshalled shape; and
the page treats a missing list as an empty one, so a node still running an older
build cannot blank the console either.

And the reason a small mistake had such a large blast radius: nothing caught it.
Each page now renders inside a boundary, so a fault costs that page and says
what it was, while the rail, the switcher and every other tab carry on. The
terminals are deliberately left outside it — they hold live WebSockets, and
remounting them to recover from somebody else's error would drop the sessions.

Mitchell-JohnsonandClaude Opus 5 acb83d3a4a A peer that never connected has no timestamp, and names are readable 
Two faults in the VPN tab, both found by running it against the real machines.

omitempty does nothing for a zero time.Time, so a peer that has never handshaken
was serialised as the year one and the page would have shown mbp14 as last seen
on 1 January 0001 instead of "never connected". The field is a pointer now, and
a test pins the JSON.

And peer names on a wg-quick host were never going to appear: /etc/wireguard is
root-only because it holds private keys, and the file was being opened as the
daemon's own user. It now falls back to reading it as root, the same way the
kernel state beside it is already read. Only comments and public keys are taken
from it.

Mitchell-JohnsonandClaude Opus 5 6f634bbe11 A VPN tab: the tunnels, and who is on them 
Beside Network, per machine. Every WireGuard interface on the machine in the
switcher, with its address, listen port and public key, and under it the peers:
name, allowed addresses, last handshake, where they connect from, and what they
have moved.

Per machine is the point rather than a limitation. The tunnel devices dial into
and a tunnel a machine dials out through are different boxes here, and putting
them on one page would invite the question of which box you were looking at.

The kernel is the truth and the configuration only supplies names: wg show all
dump has the handshakes and the counters and knows nothing but public keys, so
the # comment above a peer in a wg-quick file, or a UCI section's description on
OpenWrt, is read alongside purely to label them. Whether a tunnel is dialled or
dialling is worked out from the shape of its peers, and says neither when it
cannot tell.

Online means a handshake in the last three minutes, and the tab says so in as
many words: WireGuard is silent when idle, so there is no connection to be in.

Read-only, and no secrets leave: the private key is the second column of the
dump and is read past, pre-shared keys are noted as present and never read.

The Network tab keeps listing tunnels as the interfaces they are, and hands off
to here for anything about them.

Mitchell-JohnsonandClaude Opus 5 48d3887514 A second download source, for when the first one refuses 
Cloudflare rate-limits by volume, and the block it handed out while this was
being built lasted over twenty minutes — too fragile to be the only thing behind
a button. So the download phase tries its sources in order: the anycast endpoint
first, then a plain 100 MB file on Linode's Seattle mirror, which has no opinion
about how much has been pulled today.

Only a refusal moves to the next one; anything else would fail the same way
twice. Every result names the source it used, and the page says "from
linode-seattle" rather than "via SEA" when it was the fallback — that mirror is
in one fixed place, so somewhere else it reads low, and a figure that quietly
came from a different continent would be a lie.

Upload stays on Cloudflare, which has never been the one to refuse.

Also: the too-short-window guard was refusing to divide 512 MiB by ten
milliseconds on a link fast enough to hit the runaway budget before the first
tick. It now guards against dividing by zero and nothing more.

Mitchell-JohnsonandClaude Opus 5 2f59a54678 A Network tab, with an internet speed test 
Per machine like every other tab: the interfaces as the kernel has them
(addresses, MAC, MTU, negotiated link speed, carrier, totals, live rates from
the sampler's own sensors), the default route and resolvers, what the internet
sees of this connection, and a speed test with the last fifty results kept.

The test runs in the daemon, not the browser, so the figure is the line of the
machine in the switcher — the router's, if you switch to gate — and it carries
on when the phone locks. It measures against Cloudflare's public speed
endpoints, so there is nothing to install on any host, which is what makes it
work the same on Debian and on OpenWrt where flash is scarce.

What the measurement does and does not count:

  - Several streams, HTTP/2 deliberately off. One stream over one connection
    measures a congestion window, and HTTP/2 would put every stream back onto
    one connection and measure the same thing.
  - The first second of each phase is thrown away as the ramp.
  - A phase ends on 64 MiB as well as on four seconds, so a fast line says what
    it is without moving a gigabyte. A minimum window keeps a very fast line
    from filling the cap before there is anything to divide by.
  - Latency is the round trip less the far end's own Server-Timing. A zero-byte
    response is mostly Cloudflare's worker thinking: left in, it reported 31 ms
    for a line the edge itself measures at 3.5. Jitter is the mean change
    between consecutive probes, so one slow probe cannot run away with it.
  - The far end rate-limits by volume. So: a 20 s cooldown counted from the last
    attempt rather than the last success, streams that retry twice, the rate
    computed over the window in which bytes were actually still arriving, and a
    plain sentence when it was refused. Coasting to the end of the clock with
    nothing arriving reported a third of the truth.

The last result is published as net.internet.* sensors, each stamped with when
the test ran, so the line can be a widget, a graph, an alert or a Prometheus
series like anything else. The public address is refreshed on its own quarter
hour, which is worth having here: it is a DHCP lease and it moves.

Tests are offline — the window, the byte cap, the refusal and the cancellation
run against a local server; the route parser's byte order is pinned by a case
that would have caught the bug it did. The live measurement is behind
HAMLAB_NET_TEST=1.

Mitchell-JohnsonandClaude Opus 5 a0987c940f Twenty login tries before the backoff starts, not five 
A guest password is typed by hand off a message on a phone. Five tries is not
many when a hyphen lands in the wrong place, and being told to wait is worse
than the brute-force risk here: past twenty the doubling lockout still applies,
the global backstop is unchanged, and the password is ~78 bits.

Mitchell-JohnsonandClaude Opus 5 ed64aca63b An eye on the login form, to see what is being typed 
A guest password is read off a message and typed by hand, and from the login
form a mistyped character and a wrong password look identical. Revealed, the
field is a text field, so it also turns off capitalisation and autocorrect,
which a phone keyboard would otherwise offer for it.

Mitchell-JohnsonandClaude Opus 5 179f342a2c A guest login is a full account with a clock on it 
Mitchell, on the read-only version built earlier today: scratch it. He hands
these to people he trusts and revokes them otherwise, so a console with half
its tabs missing solved a problem he doesn't have.

So the allow-list, the middleware check and every "not for a guest" branch in
the UI are gone. What is left is the part that was the point: a throwaway
account that expires by itself, is checked on every request, swept once a
minute, and can be ended in one tap. A guest now gets the whole console on
every machine, terminal included.

Said once, since it is his call and he has made it: that means a guest has a
root-capable shell on every host, and can make an account or a token of its own
that outlives the guest login.

Mitchell-JohnsonandClaude Opus 5 8a7167bf03 A guest login: temporary, look-only, revocable 
Users -> Guest logins makes a throwaway user name and password, good for half
an hour by default, to hand to somebody who wants to see the console. It is a
normal account with `guest: true` and an expiry, so login, sessions and the
saved look need no special case, and it is left out of the account list, out of
"the last account can't be removed", and out of the one account an empty user
name means.

What a guest may do is one allow-list, checked in the auth middleware, rather
than a flag ~190 handlers have to remember. The list is matched by asking the
router which handler a request would reach, so it cannot drift from the routes
it names, and it is checked against the scoped path — /api/nodes/grid/procs is
/api/procs on grid — because the hub proxies to a node with a token that is
full control of that node. The node cannot tell a guest from its owner, so the
only place it can be stopped is here, before the request leaves.

A guest gets the dashboard, containers, stacks, disks, hardware, ZFS and usage,
on this machine and on any managed one, and nothing else: no terminal (attaching
is a GET, and it is a root shell), no files, no container logs or environments,
no stack files, no alert channels, no cron, no tokens, no settings, no power.

Expiry is enforced on every request and swept once a minute, so a console left
open on a visitor's phone stops within the minute rather than at their next
click; revoking signs them out at once. The console hides what a guest cannot
use and says how long is left where the power button would be.

Mitchell-JohnsonandClaude Opus 5 4450f1285d Install under procd, so OpenWrt counts as a host too 
The binary was already static and musl-clean; the only thing standing between
Ham Lab and an OpenWrt box was that setup.go knew systemd and OpenRC and
nothing else, so an install there ended at "nothing starts it at boot."

Adds an embedded procd init script, detected on /sbin/procd + /etc/rc.common
ahead of the OpenRC branch. Both backends write /etc/init.d/hamlab, so
uninstall tells them apart by USE_PROCD=1 rather than by path.

Verified on the new router: procd supervises the instance, S95/K10 symlinks
land, and the hub drives its Docker and stacks like any other node. The
Updates tab needed nothing — apk-tools 3 answers the same query Alpine's does.

Mitchell-JohnsonandClaude Opus 5 4e3c817b2a A Recreate action, and the Updates tab uses the whole window 
Recreate is `up -d --force-recreate`. It exists because Deploy and Update
both leave a container alone when its definition has not changed, which is
precisely the state a container is in when Docker will not start it — pinned
to a network that has since been recreated, answering "network … not found"
to everything. siyuan landed there today and there was no way out from the
console.

The Updates tab is a page, not a list with a detail pane, so on a wide window
it was being squeezed into the right-hand half with an empty list column
taking the left — which read as a phone layout on a desktop. It now sits
under the tab strip at full width. The list-and-detail tabs are unchanged.
The rule needed :not(.has-sel) to outrank the wide-window rule that grows the
list to fill the row.

Mitchell-JohnsonandClaude Opus 5 94800b8207 Update from the list that says what is out of date 
The Updates tab could tell you eleven images were behind and offer nothing to
do about it; updating meant knowing which stack each image belonged to and
going to find it. Now each row has Update and the header has Update all.

Updating is per stack, because that is the unit compose deals in, so a row
acts on whichever stacks use that image — postgres:15-alpine is wikijs's,
postgres:17 is vikunja's — and Update all walks the affected stacks through a
queue one at a time, with each task's output on screen, rather than
recreating half the machine at once. A stack that finishes says "updated just
now" rather than re-checking, since every check is a registry request and
Docker Hub counts them.

Also: cron expressions read as English. "daily at 3:15am", with 15 3 * * *
kept beside it. Jobs.tsx had a smaller version of this for its own list; it
now uses the shared one, which handles lists, ranges, steps, names,
weekdays/weekends, midnight and noon, and says nothing at all when it is not
certain — the caller falls back to the expression.

Mitchell-JohnsonandClaude Opus 5 03e0761f3e Hardware: a Motherboard card 
The board, the chassis and the firmware on it, which the System card was
reducing to two lines. Maker, model, version, serial and asset tag; chassis
and where the board sits in it; the firmware's vendor, version, revision,
date, ROM size and whether the machine boots UEFI — that last one is a line
in SMBIOS's characteristics list rather than a field, so the parser now keeps
those lists too.

Expansion slots come with it, with the device found at each occupied slot's
PCI address rather than the address alone. They are only shown when the
firmware tracks occupancy at all: core's NucBox lists five PCIe x1 slots it
does not physically have, all "Available", copied out of a reference design.
grid's board reports real addresses and real occupancy, which is the case
worth printing.

A machine with no SMBIOS gets a card that says so.

Mitchell-JohnsonandClaude Opus 5 776bcb236d A Hardware tab: what the machine is made of 
Per machine, like every other page. Four tiles — processor, memory, storage,
graphics — over a card for each.

Memory is the part that had nowhere to live before: every slot, with the
module's size, type, form factor, rated and running speed, maker, part
number, serial, rank and voltage, and the empty slots marked empty. A module
whose maker is only a JEDEC id gets a name when it is one we know and keeps
the number when it is not, because a wrong name is worse than a code.

Everything is read from what Debian already has: dmidecode for the parts only
the firmware knows, lscpu, lspci, sysfs. None of it changes under a running
kernel, so it is read once and kept for ten minutes; Re-read is for the one
thing that does change, a drive plugged in.

Every reader is allowed to come back empty. A machine with no dmidecode, no
root to read it with, or no PCI bus at all still gets a page, with a note
saying what was missing and why. Checked against the Mac mini, which is all
three cases at once: no SMBIOS memory table, a GPU only the device tree knows
about, and cores that are not all alike — lscpu counts one cluster as "cores
per socket" there, so without SMT the thread count is the honest answer.

Mitchell-JohnsonandClaude Opus 5 09dc846730 docker: logs follow a held connection, and networks can be removed 
Two gaps the Docker tab had against Dockhand and against its own Services
tab next door.

Logs: one `docker logs -f` per viewer over a WebSocket, the shape the
Services tab's journal tail already uses, instead of asking again every two
seconds. stdout and stderr both, with stderr marked so the page can colour
what went wrong. Docker replays the backlog down two pipes in no particular
order, so the opening 300 ms is held and sorted by the stamp Docker wrote;
after that the log is live and in order. A reconnect resumes from the last
line rather than from the top — `--since` is inclusive and two lines can
share a nanosecond, so the client drops what it has already shown by line,
not by "later than". A container that has stopped ends the stream at once,
so reconnects back off to 15 s.

Networks: remove and prune, which images and volumes have had all along.
The overview now says which containers are attached to each network, so the
✕ appears only on one nothing uses, and never on bridge, host or none.
`network rm` prints the real reason and then an aggregate "exit status 1",
so the message shown is the first line, not the last.

Prune is not exercised against `core`: several networks here belong to
stacks that are merely down, and pruning would give them new subnets on
their next deploy.

Mitchell-JohnsonandClaude Opus 5 f17a365ea1 stacks: remember where a container's bind mounts pointed 
Every stack on core and grid is labelled with a path inside Dockhand's
filesystem — /app/data/stacks/… — because Dockhand ran compose from inside its
own container. Ham Lab resolves those by walking the bind mounts of running
containers, which works right up until the container doing the mounting is
removed. Retiring Dockhand would, in one step, make seventeen stacks on core
and five on grid unfindable.

So the mounts are written down as they are seen, and a path no live container
explains is looked for in what was seen before. A remembered mount resolves
with no container to run in, which is the right answer: compose runs on the
host, against the host's own copy of the file.

The same problem bites a scheduled update, which captures how to invoke
compose when it is made so the cron job never has to rediscover the world at
3am. repoint() checks the named container is still running and falls back the
same way if it is not — and pointedly leaves the spec alone if nothing
explains the path, so it fails loudly rather than deploying a guess.

Out in cron the record is read and never added to: the daemon owns state.json
and would clobber anything written from there.

Mitchell-JohnsonandClaude Opus 5 192504ead3 docker: the eight things Dockhand did that Ham Lab did not 
Dockhand is being retired, so the Docker tab has to cover what it actually
earned its keep doing. Eight pieces, all per container or per machine:

- Stats: CPU, memory and IO over time, from sensors already collected.
- Health: the container's own healthcheck, with the last few probe outputs —
  which is where a failing check says why.
- Events: `docker events` keeps a minute of backlog and nothing more, so Ham
  Lab follows the stream and keeps a ring of its own. A restart at 4am is
  still there at 9.
- Shell: `docker exec` into a container, in the terminal already here.
- Limits: memory, CPU and restart policy changed live, without hand-editing
  the compose file for a number you want to try.
- Updates: what the registry has that this machine does not, for every image
  at once rather than one stack at a time.
- The same across every machine, asked of the hub — which is the only thing
  that can reach them all.
- Schedules: a real line in /etc/cron.d/hamlab-docker calling the binary,
  in the same shape as the ZFS snapshot schedules. Dockhand updated DNS and
  ingress nightly from a ticker inside a web app; a cron line keeps running
  when the console does not, and is visible to anyone reading the machine the
  normal way.

internal/compose is new and shared, so a deploy from the console and a deploy
from cron invoke compose identically — including the case where compose has to
run inside the orchestrator's own container, where the paths are that
container's and not the host's.

Mitchell-JohnsonandClaude Opus 5 a70f3e2ed2 Container events are Ham Lab's own record, not Docker's short memory 
docker events is a live stream with a small in-memory backlog: ask for thirty days and you
get a few minutes, and a daemon restart loses the lot. That is why Dockhand kept its own
copy. A watcher now follows the stream and appends lifecycle events to a ring beside the
config, flushed every thirty seconds, so the question of what happened to a container last
week has an answer. Health-check exec events are excluded — three per probe, thousands a
day, and the health panel says it better.

Mitchell-JohnsonandClaude Opus 5 b3e1c495f0 Docker: a container's stats, health, events, shell and limits 
Five things the tab could not do, all on the container detail.

Stats draws CPU and memory over time from the container sensors the sampler already keeps,
so there is nothing new to collect.

Health shows the check's verdict, the failing streak and what the last five probes actually
printed, and says plainly when an image defines no health check at all rather than leaving
a blank panel.

Events asks Docker what has happened to the container over the last day, week or month —
started, died, killed, health going bad, with exit codes — rather than keeping a copy that
would only go stale.

Shell opens a session inside the container as an ordinary terminal, so it reattaches,
resizes and scrolls back like the rest and works on a managed machine through the same
proxy. The terminal manager grew a CreateCmd for it; every session is the same thing
afterwards.

Limits changes memory, CPUs and restart policy on the running container with docker update,
live and without recreating it. That is also the catch, and the dialog says so: it does not
edit the compose file, so a deploy puts back whatever the file says.

A read-only version was built first and **cut the same day**: Mitchell hands these to people he trusts and revokes them otherwise, so a console with half its tabs missing was solving a problem he doesn't have. Consequences, stated once and accepted: a guest has the Terminal tab, which is a root-capable shell on every host, and can make an account or token of its own that outlives the guest login. The one thing a guest is not is *an account*: it is left out of the Users list, out of "the last account can't be removed", and out of the single account an empty user name resolves to. |

The switcher is the only place a machine is chosen, so there is exactly one answer to "which machine am I looking at" — a page that quietly reaches across breaks that, and it is never obvious which machine an action would land on. The hub still *proxies* for a node, and hub-only admin (Machines, Users, Settings, Alerts) is unaffected. |

- **Updating from the Updates tab** — **shipped 2026-09-26**: the "what is out of date" list
was read-only, so seeing a newer image and doing something about it were different places.
Each row now has **Update**, and the header has **Update all**. Updating is per stack —
that is the unit compose deals in — so a row acts on whichever stacks use that image, and
several stacks run through a queue one at a time rather than recreating half the machine at
once, each with its task output on screen. A row that succeeds says "updated just now"
instead of re-checking, since a check is a registry request.
- **Recreate, and the Updates tab at full width** (2026-09-26): a stack's actions gained
**Recreate** (`up -d --force-recreate`), the only way out of a container Docker refuses to
start — one pinned to a network that has since been recreated answers "network … not
found" to Deploy and Update alike, because as far as compose is concerned nothing about it
changed. Found the hard way when a SiYuan update landed in exactly that state. The Updates
tab also stopped rendering as a list-and-detail pair: it is a page, not a list, so on a
wide window it now sits under the tab strip at full width instead of being squeezed into
the right-hand half beside an empty column.
- **Cron in English** (`crontext.ts`, 2026-09-26): schedules read "daily at 3:15am" rather
than `15 3 * * *`, with the expression kept beside it. Handles lists, ranges, steps, day
and month names, `@daily` and friends, weekdays/weekends, midnight and noon — and declines
to describe anything it is not sure of, because a confident wrong sentence is worse than
five fields. The Jobs tab had its own smaller version of this; it now uses this one.
- **Hardware tab** — **shipped 2026-09-25** (`internal/hardware`, `internal/api/hardware.go`,
`Hardware.tsx`): what the machine is physically made of, per machine like every other page.
Four headline tiles (processor, memory, storage, graphics) over cards for each: the
processor with its cores, clock range, socket, caches, microcode and the handful of feature
flags anyone asks about; **every memory slot** with size, type, form factor, rated and
running speed, maker, part number, serial, rank and voltage, and the empty ones marked
empty; each drive with model, size, bus, firmware and serial; each display adapter with its
driver, PCI address and video memory; and the board itself — model, firmware and date,
serial, kernel. Read from what Debian already has (dmidecode for what only the firmware
knows, lscpu, lspci, sysfs) and cached for ten minutes, since none of it changes under a
running kernel; "Re-read" is there for the one thing that does, a drive plugged in.
Every reader may come back empty and the page says what it could not read and why: a
machine with no dmidecode, no root, or no PCI bus still gets a page. Verified on `core`
(SMBIOS, Intel graphics) and on the Mac mini (Asahi: no SMBIOS memory table, a
device-tree GPU, heterogeneous cores — where lscpu's "cores per socket" counts one
cluster, so without SMT the thread count is the honest core count).

## Network tab (2026-09-27)
A **Network** tab, per machine like every other: the interfaces as the kernel has them
(addresses, MAC, MTU, negotiated link speed, carrier, byte totals, live rates from the
sampler's own sensors), the default route and resolvers, what the internet sees of this
connection, and an **internet speed test**.
Decisions worth keeping:
- **Measured by the daemon, not the browser.** The test runs on the machine in the switcher,
so the figure is that machine's line — the router's, if you switch to `gate` — and it
carries on if the phone locks or the tab closes. The page polls a run it is not driving.
- **No tool to install.** It measures against Cloudflare's public speed endpoints
(`__down`, `__up`, `cdn-cgi/trace`), which is what makes it work identically on Debian and
on OpenWrt, where `opkg install` costs flash. That is the feature's one external
dependency, and it is named in `internal/network/speedtest.go`.
- **Several streams, HTTP/2 off, and the ramp thrown away.** One stream over one connection
measures a congestion window; HTTP/2 would put every stream back on one connection and do
the same. The first second of each phase is measured and discarded.
- **Latency is the round trip less the far end's own Server-Timing.** A zero-byte response
is mostly Cloudflare's worker running — 20 to 45 ms of it against a few ms of wire. Left
in, it reported 31 ms for a 7 ms line. Jitter is the mean change between consecutive
probes, not a standard deviation, so one slow probe doesn't run away with it.
- **A refused phase is not a number.** The far end rate-limits by volume, and a test moves a
few hundred megabytes; several in a row earn 429s, and the block observed while building this
lasted over twenty minutes. So: a 20-second cooldown counted from the last *attempt* (a
refused test still used the line), a stream that retries twice before giving up, the rate
computed over the window in which bytes were actually still arriving, and a plain sentence
when it was cut short. Coasting to the end of the clock with nothing arriving reported a
third of the truth.
- **A second download source, for when the first refuses.** A plain 100 MB file on Linode's
Seattle mirror, which has no opinion about volume. It is only reached after a refusal, and
every result names the source it used — that mirror is in one place, so on a machine far from
Seattle it would read low, and a number that quietly came from somewhere else would be a lie.
Upload stays on Cloudflare, which has never been the one to refuse.
- **The last result is published as sensors** (`net.internet.*`), so the line is a widget, a
graph, an alert or a Prometheus series like anything else. Each carries the time the test
ran, not the time it was asked for.
- **Not scheduled.** Nothing takes a speed test on its own. A nightly one recorded to the
history is the obvious next step and deliberately not built yet — the cron shape for it
already exists twice over (ZFS snapshots, Docker image updates).
## VPN tab (2026-09-27)
A **VPN** tab beside Network, per machine: every WireGuard tunnel on the machine in the
switcher, and the devices on it — name, address, last handshake, where it connects from, and
what it has moved.
- **Per machine is the point, not a limitation.** The tunnel people dial into and a tunnel a
machine dials out through are on different boxes here (`gate` and `hamtv`), and a combined
view would invite exactly the question "which box is this on".
- **The kernel is the truth, the config only supplies names.** `wg show all dump` has the
handshakes and counters and knows nothing but public keys; names come from the `# comment`
above a peer in a wg-quick file, or a UCI section's `description` on OpenWrt. Both are read
only to label what the kernel already said.
- **Server or client is worked out, not declared.** A peer allowed `0.0.0.0/0` that has an
endpoint is a way out, so a tunnel holding one is this machine dialling out; a tunnel with a
listen port and peers is one being dialled. Anything else says neither rather than guessing.
- **"Online" is a handshake in the last three minutes**, and the tab says so. WireGuard is
silent when idle; there is no connection to be in, and a tab claiming otherwise would be
lying twice a day.
- **Read-only, and no secrets.** Private keys are in the second column of the dump and are
read past; pre-shared keys are noted as present and never read. Adding or editing peers is
not here: it means generating keys and writing the machine's network configuration, which is
a bigger thing than this tab, and a bad thing to get half right.

that record when no running container explains its path, running compose on the host

// The speed test. It measures against Cloudflare's public speed endpoints, the same ones
// speed.cloudflare.com uses: a plain GET of N bytes down, a plain POST of N bytes up, and a
// zero-byte GET for the round trip. No account, no API key, nothing to install, and an edge
// close to every one of these machines.
//
// The method, since a number without one means little — it is stated in the UI too:
//
// - Latency is the round trip of a zero-byte response on a connection that is already open,
// less the time the far end says it spent on the request (its Server-Timing header). That
// subtraction is the difference between measuring the line and measuring Cloudflare's
// thinking time: a zero-byte response is almost entirely the latter — tens of
// milliseconds of worker, against a few of actual wire. The figure reported is the best of
// several probes; jitter is the average change from one to the next.
// - Download and upload each run several streams at once for a fixed few seconds. One
// stream measures one TCP connection's congestion window as much as the line, which is
// why every speed test ever made uses more than one.
// - The first second of each phase is thrown away. That is the ramp: counting it reports a
// number nobody's connection ever actually did.
// - Each phase is capped in bytes as well as seconds, so a very fast line cannot run away
// with the meter.
//
// The one thing to know about the far end: it rate-limits by volume, and a test moves a few
// hundred megabytes. Several in a row will start earning 429s, which is why there is a
// cooldown between tests and why a phase that gets refused says so instead of reporting the
// decayed figure it would otherwise compute.
//
// HTTP/2 is deliberately off: over one HTTP/2 connection the streams would share a single
// congestion window, which measures the window, not the line.
