Three questions instead of one, because the two the original never asked are the
two that decide whether the thing is useful.
1. Do you want one, with the explanation first.
2. Where. Home (easiest to find again months from now), beside Officer, or a
path typed in. This is not tidiness: the checker measures its own directory,
so a ballast only protects the filesystem it sits on. Choosing where it goes
is choosing which mount is covered.
3. How much, as 5/10/20% — with the actual numbers, and with what would be LEFT
rather than only what is taken:
[1] 5% — reserves 2.9GB leaving 54.3GB free
[2] 10% — reserves 5.8GB leaving 51.4GB free
[3] 20% — reserves 11.5GB leaving 45.7GB free
A percentage on its own is unanswerable. The number that decides it is the
one on the right: the reserve has to be big enough to matter and small
enough not to be the thing that filled the disk.
The size is computed against the filesystem the chosen path lands on, after the
location is known, so the percentages are of the right disk. ballast_free_kb
walks up to a directory that exists, since nothing has created the target yet.
An existing ballast in either default location is found and left alone rather
than a second one being made beside it.
Verified end to end in a temp home: created at the chosen path, 2.9G for 5% of
57.1GB, checker installed and reporting it present.

OFFICER_ROOT, defaulting to <user home>/officerdev. One directory holding the
four things Officer is made of, per docs/sidecar-app-store.md — the app, its
data, the item store, and any containers the app store provisions — so the whole
installation can be moved, backed up or deleted as a unit.
Asked at the start with the other questions rather than at the point it is first
needed. It decides the shape of several later steps: where the repository is
cloned, where DATA_PATH sits beside it, and which filesystem the app store's
bind mounts come out of. Asking once up front also means the run can be described
before it starts rather than discovered as it goes.
A leading ~ is expanded explicitly. It arrives as a literal from a read or an
environment variable — nothing expands it there — and would otherwise create a
directory actually named "~" in whatever the working directory happened to be.
Relative paths are refused with the value named, and a trailing slash is trimmed
so the path composes cleanly with what gets appended to it.
Nothing creates the directory yet; that belongs to officer-setup. This records
the answer and reports it, including whether it already exists.
Verified: Enter takes the default, ~ expands, trailing slash trims, OFFICER_ROOT
in the environment skips the prompt, and a relative path fails with the value
named.

New first section, before anything else that changes the machine, because the
swapfile and the ballast both size themselves from free disk.
Ubuntu Server's installer on its defaults gives the root logical volume a fixed
size and leaves the rest of the drive as unallocated extents in the volume group.
On a 2TB disk that is a ~100G root with nothing to indicate a problem: lsblk
shows the whole drive, df shows 100G, and the two are never seen side by side
until the day it fills. Growing a virtual disk at a provider leaves the same
shape one layer down, and so does resizing a partition without telling the
filesystem inside it.
Three layers, any of which can be the short one, so all three are measured and
printed together:
drive: 76.3GB /dev/sda
volume: 76.1GB /dev/sda1
filesystem: 76.1GB ext4, mounted at /
Seeing them in one place is most of the value. The fix is then whichever layer is
short: lvextend for free extents, growpart for a partition that stops early
(followed by pvresize and lvextend when LVM is in the way), or resize2fs alone
when only the filesystem is behind.
Only ever grows. Nothing here shrinks, creates or deletes a partition, and ext4,
xfs and btrfs all grow while mounted — so no unmount, no reboot, and a failure
part-way leaves a smaller filesystem on a larger container, which is the state it
started in.
growpart is the authority on whether a partition can move — it exits 1 with
NOCHANGE when the partition already reaches the end — but it comes from
cloud-guest-utils, which is not on every image. Installing a package purely to
ask a question is too eager, so plain arithmetic on the device sizes decides
whether it is even worth looking, and only then is growpart fetched.
A gigabyte of slack before anything is reported: a filesystem is always slightly
smaller than its container, and reporting journal and reserved-block overhead as
reclaimable space would make this section cry wolf on every machine.
Verified on this host: plain ext4 partition filling its disk, correctly reports
nothing to reclaim, and every helper returns the right device and size.

Swap covers memory pressure. These are its neighbours:
8. Emergency disk ballast the same valve, for disk
9. earlyoom what happens when swap runs out too
10. inotify watch limit the silent one
All three follow the rule this script now works to: the role sets which way the
recommendation points, never whether the question is asked. A dev machine is
still offered the ballast, with the recommendation pointing the other way; a
server is still offered the inotify raise, because anything running `bun --watch`
or serving a file browser is a watcher too.
The ballast is section 22 of the original, moved up beside swap where it belongs
and moved out of the user's home. The original wrote the checker into
$USER_HOME/.local/bin and ran it from a root cron — a root cron executing a
script in a directory its owner can write is a privilege escalation waiting to be
noticed. Moot on a box where that user already has passwordless sudo, but wrong.
Both the checker and the file are in root-owned system paths now.
Two bugs found by running the generated checker rather than reading it:
It df'd the ballast's own directory, which does not exist before the ballast is
created — and with `set -euo pipefail` that meant cron mailing an error every
ten minutes. It now walks up to a directory that exists, and the installer
creates the directory itself rather than depending on the create step.
The inotify text claimed a default of 8192. This host is at 29461: Ubuntu
raised it, and stating a number the reader can see is wrong on their own screen
undermines the rest of the explanation. It now describes the failure instead
and prints the machine's actual value.
earlyoom is a distro package and a systemd unit, so it is checked with
`systemctl is-active` and reports honestly when it installs but fails to start.
Verified: checker --status and its no-op path both exit 0 with no directory
present, and the helpers report correctly against this host.

Four things the original got wrong, all of which only show up on a machine that
is not this one:
It detected swap with `swapon --show | grep -q '/'` — a test for a swap FILE.
A machine using zram or a swap partition reports no swap at all, and the step
would add a swapfile beside working swap. Reads SwapTotal from /proc/meminfo
now, which covers every kind.
It never looked at free disk. On a VPS with 4G free and 16G of RAM it would
fallocate 8G, fail, and take the run down under `set -e`. The recommendation is
now capped by what is actually there, keeping 5G back, and refuses rather than
shrinking to something useless.
fallocate was assumed to work. It produces a file that btrfs and zfs will not
swap on, so dd is the fallback — slow, but it always works.
swappiness was written by sed'ing /etc/sysctl.conf in place, tangling it with
whatever else lives there. It is a drop-in at /etc/sysctl.d now, so what this
script set is visible as its own file.
Role-dependent, which is the first use of MACHINE_ROLE: swappiness 10 on a
server, where swapping is the emergency valve and a page fault on a request path
is latency somebody is waiting for; the kernel default of 60 on dev, where
swapping out an application nobody has touched in an hour is exactly what you
want.
WSL is left alone entirely — WSL2 runs its own managed swap inside the VM, and a
swapfile written here is wasted disk the kernel will not use.
Sizes are reported rounded rather than floored. A 4 GiB swapfile is 4194300 kB,
which floors to 3 and reads as though a gigabyte went missing. Free disk stays
floored, deliberately: it decides how much to allocate, and rounding up invents
space.
Verified on this host — 4G RAM, 4G existing swap correctly detected and left
alone — and with the disk check stubbed at 6G free (caps to 1G) and 3G free
(refuses).

The refresh lived inside "System update", which `step` skips when its name is
already in the progress file. So a resumed run — the common case, since that is
what the progress file is for — installed core utils, added the fastfetch PPA and
set up the Docker repo against whatever the index happened to say hours or days
earlier. On a box left overnight that is a stale index and a "package not found"
somewhere unrelated.
It now runs in pre-flight, unconditionally, before any step exists to skip it.
`apt-get upgrade` stays where it was and stays confirmable: refreshing the index
changes nothing on the machine, upgrading is the one thing that does.

The original took whatever was typed and handed it straight to timedatectl. An
unknown zone — a typo, a guess at the spelling — fails there, and under `set -e`
that takes the whole run down four steps in. Names are now checked against
/usr/share/zoneinfo before use, and a bad one just re-asks.
It also never showed what the machine was already set to, and defaulted to option
1 (UTC) on Enter, so pressing return on a correctly-configured box silently moved
it. Now the current zone is printed, Enter keeps it, and a zone equal to the
current one reports nothing to do rather than setting it again.
timezone_current reads three sources — timedatectl, /etc/timezone, then the
/etc/localtime symlink — because they differ in availability rather than in
answer: timedatectl needs systemd, /etc/timezone is Debian's, and the symlink is
the one that is always there. timezone_set writes through timedatectl where
there is a systemd to talk to and the files directly otherwise, which is what it
would have written anyway; that is also the WSL path, where timedatectl exists
but does nothing.
Europe/Berlin added to the shortlist; TIMEZONE in the environment answers the
prompt ahead of time and is validated the same way, failing early with the bad
value named.
Verified detection (UTC here), validation of four names, and the env-var
rejection path.

Was three unconditional lines that ran on every pass and reported success either
way. Now it checks, says what it found, and asks.
The original tracked one fact where there are two:
what a new login shell is told to use LANG in /etc/default/locale
whether that locale actually exists whether it has been generated
Setting the first without the second is what produces "setlocale: LC_ALL: cannot
change locale" on every ssh login and every perl invocation. They fail
differently, so the step names whichever one is actually missing rather than
reporting a flat "locale not set".
Also fixes two things the original would have hit on a minimal image:
locale-gen comes from the `locales` package, which cloud base images do not
ship and which is not in core utils. It is installed on demand rather than
assumed, instead of failing with "locale-gen: command not found".
The locale is uncommented in /etc/locale.gen rather than only passed to
locale-gen as an argument. A locale generated by argument alone disappears the
next time anything regenerates from that file.
`locale -a` prints en_US.utf8 where the configuration spells it en_US.UTF-8, so
both sides are folded before comparing — a literal match reports a working locale
as missing.
LOCALE in the environment overrides the default. pacman, dnf and brew branches
are written but unreachable while the pre-flight gate is apt-only; macOS has no
system locale to set and says so.
Verified both paths on this host: en_US.UTF-8 reports already set and generated,
pt_PT.UTF-8 correctly reports both facts missing.

"the only step that changes software already on this machine" is true, and
reads like a warning about something dangerous rather than a description of
apt upgrade. The reasoning stays in the section comment, where it explains why
this is its own step; the prompt just says what it does.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The section asked "Proceed?" without saying what it was proposing to change —
the one question in the script where the answer matters most, since it is the
only step that moves versions of software already on the machine.
pkg_upgradable now names them, from `apt-get upgrade -s`: the same calculation
the real run does, as opposed to `apt list --upgradable`, which also lists
packages held back that would not actually move.
Nothing to upgrade means no prompt at all, and the summary says so rather than
claiming an upgrade happened. The list is capped at 25 with a count of the rest,
because a box untouched for months lists hundreds and a wall of names is no more
informative than the number.
Verified against this host (0 upgradable, so it reports current and does not
ask) and with a stubbed 40-package list for the cap.

Three sections where there were two, and none of them touches the machine until
you say so:
2. System update upgrades what is already installed
3. Core utils what the distribution provides
4. Command-line tools lazydocker, lazygit, starship, fastfetch
The split matters because these are different kinds of change and deserve
separate answers. System update is the only step in the whole script that moves
versions of software already on the machine; core utils only ever adds what is
absent; and the four tools are upstream binaries the distribution does not ship
at all. Previously the update and the core packages were one step and the tools
were tacked onto the end of it, so agreeing to "essentials" meant agreeing to all
three at once.
Every section now prints what it will install and what it is leaving alone, then
asks. Enter means yes — unlike the machine-role question, which has no default,
because these are "do the thing you already asked for" and making twenty of them
require a deliberate keystroke would train people to hold the y key down.
ASSUME_YES=1 answers all of them for an unattended run, and EOF fails with that
named rather than spinning.
Refusing is recorded rather than glossed: LAST_SKIPPED feeds the summary, so a
declined section reads "Core utils: SKIPPED by request — cowsay neofetch" instead
of quietly reporting nothing installed.
Nothing to install means no prompt at all — there is nothing to agree to.
announce_plan takes the array NAMES rather than their contents, because once a
list has been through word splitting an empty one cannot be told from a missing
one.
Verified all three paths: accept, refuse, and nothing-to-do.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The summary claimed credit for everything in a section's list, including the
packages it had just decided to leave alone — so a run that installed nothing
still ended with "Command-line tools: lazydocker lazygit starship fastfetch".
The announce above it said "nothing, all present" in the same breath.
pkg_install and tools_install now record LAST_INSTALLED and LAST_KEPT, and
summarise_last turns those into one honest line:
Core packages installed: btop tmux (17 already present)
Command-line tools: already present, nothing installed
Verified all three shapes — everything present, nothing present, and mixed.

No default, and it is the only question in the script like that. A guessed
default is right often enough to be trusted and wrong in exactly the case that
costs the most — pinning a static IP on a rented box, or leaving the firewall
open on one. Every branch downstream is about what this machine is exposed to,
so it is worth one deliberate keystroke rather than an Enter.
Empty and unrecognised answers re-ask rather than aborting; a failed read means
EOF rather than a wrong answer, and fails with the environment variable named,
because otherwise the loop spins forever the first time this runs unattended.
Drops guess_machine_role, which existed only to supply that default. default_iface
stays — the static IP section needs it when it is ported.
MACHINE_ROLE in the environment still answers it ahead of time.

Your call, and the right one. Editing in place let mis-grouped code sit unnoticed
until it scrolled past in a live run — which is exactly how the four upstream
binaries buried in "System Update & Essentials" were found. Porting forces the
question of where each thing belongs before it runs, not after.
machine-setup.sh now contains only what has actually been worked through:
pre-flight, system update and core packages, command-line tools, and the summary.
1149 lines down to 172. The sections still to come are listed in a NOT PORTED YET
block, in order, and each arrives as its own commit.
The original is beside the other superseded scripts as
scripts/setup-old/setup-ubuntu.sh — verified byte-identical to the live
/root/ubuntu-setup copy — so porting reads from a file in the repo rather than
from root's home.
Two claims trimmed from the ported summary, because they were true of the old
script and not of this one yet: it reported the shell as "zsh (Oh My Zsh +
Starship)" unconditionally, and told you to reconnect as a user it had not
created. Replaced with what pre-flight actually knows — system, role, user.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
lazydocker, lazygit, starship and fastfetch were buried inside "System Update &
Essentials", after the package install and with no announcement — so a run
appeared to be installing system packages and then started pulling tarballs and
printing a five-shell starship tutorial. They are a different thing: upstream
binaries on their own release cadence, not anything the distribution ships. Now
their own step, announced in the same shape as the package section.
Each is checked before it is fetched. The original re-ran every installer on
every run, which is why a machine that already had starship got it reinstalled
along with its "add this to your ~/.zshrc" instructions — advice this script
does not want followed, since it writes the shell config itself. Its output is
now dropped; errors still surface.
Two real bugs fixed on the way:
lazygit's asset name was hardcoded to x86_64, so on arm64 the download 404s
and tar fails partway through the run. It now maps ARCH, and spells the
architectures the way lazygit does rather than the way we do.
The version was extracted with `tr -d 'v'`, which deletes every v in the
string rather than the leading one. `${version#v}` instead.
fastfetch stays a package but stops assuming the PPA is needed: Ubuntu picked
it up in 24.10, so the repository is now checked first and the PPA added only
where the archive has nothing. Verified on this host — noble genuinely has no
candidate, so the PPA is still the only source here.
Verified both branches of tools_install by stubbing the presence check.

A WIP boundary after section 2 so the finished part can be run start to finish
on its own, without the untouched sections below acting on the machine. It moves
down as each section is worked through and goes away when the walk ends.
Also ignores .setup-progress, which the script writes beside itself and is
per-machine. The exit message names it, because with it in place a second run
skips section 2 and the rewritten part cannot be re-felt from scratch.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
lib/packages.sh, and section 2 wired to it.
The rule it exists to enforce: `apt-get install <present-package>` is not a
no-op, it upgrades the package if the repository has a newer one. On a machine
somebody already uses that silently moves a version they chose, and a setup
script is the last thing that should do that behind their back. pkg_install
queries the package database first and names only the genuinely absent packages
on the command line — a package already installed is never passed to apt at all.
It also says so out loud, every time, because a provisioning run should not be
opaque about what it is doing to the machine:
:: Core packages — installs what is missing, keeps what you already have
already here: curl ca-certificates gnupg git jq …
to install: btop tmux
Section 2's flat list of 19 is now pkgs_core(), split per package manager rather
than through a canonical-name table with overrides. The names genuinely disagree
(build-essential/base-devel, fd-find/fd) and three of them are not packages
elsewhere at all — apt-transport-https, lsb-release and software-properties-common
are apt concepts that exist to let later steps add the Docker repo and the
fastfetch PPA. A `case $PM` shows what each system actually gets, in one place.
Of those 19, six are load-bearing and the rest are the environment. Only
build-essential reaches beyond itself: it is a meta-package, so on a box with a
pinned gcc it pulls the distribution default alongside. Noted where it is
declared; it is the first thing to move out of core if that ever bites.
apt-get upgrade stays, but as its own announced step — it is the one place that
deliberately moves versions, rather than something that happens as a side effect
of asking for a tool.
DEBIAN_FRONTEND=noninteractive and NEEDRESTART_MODE=a now live inside the
helpers. needrestart has been on by default since Ubuntu 22.04 and stops to ask
which services to restart, which is how an unattended run ends up silently
waiting for a keypress.
dpkg-query on the status field rather than `dpkg -s`, which also succeeds for a
package removed but leaving its config behind — that state would read as present
and never be reinstalled.
Verified against this host's real dpkg database: all 19 report present, and a
mixed list correctly passes only the absent ones through.

MACHINE_ROLE is homelab, vps or dev, and several steps have a different right
answer per role with no way to work it out themselves: whether the address is
yours to pin (static IP), whether the box faces the open internet (fail2ban, SSH
hardening, UFW), and whether it is allowed to sleep (suspend, logind).
Asked in pre-flight rather than at each point of use. The steps that care run
from swap through to the firewall, and being asked "is this a VPS?" for the
fourth time halfway down a provisioning run is how people start answering
without reading.
The default offered is guessed from whether this machine's own address is in
RFC1918 space, which beats asking whether it is virtualised — a homelab is very
often a VM on Proxmox and would be misread as rented — and is the same fact most
of the branches turn on anyway. A graphical session means dev; so does macOS.
It is only ever a suggestion the user confirms.
MACHINE_ROLE in the environment answers it ahead of time for an unattended run,
which is why it is declared with :- rather than a plain assignment. The first
version wiped the caller's value before ask_machine_role ever saw it; caught by
running with MACHINE_ROLE=vps and watching the menu appear anyway.
Verified: guesses vps on this host (public IPv4, no DISPLAY, no display
manager), env override takes, and a bad value fails with the three valid ones
named. Nothing consumes the role yet — the steps get wired as each is worked
through.

scripts/setup/ is now what the new installer is being built in — machine-setup/
for the box, officer-setup.sh for the platform on top — and everything being
replaced moved to scripts/setup-old/. It still works and is still what to run.
Three things the move broke, and what each needed:
starship.toml is not an old-setup artifact. os-user-shell.ts reads it at
RUNTIME to seed a member's ~/.config/starship.toml when their Linux account is
provisioned, and line 125 reads it inside a try whose catch returns
"could not read the shell templates" — so account provisioning would have
failed outright, not degraded. Moved back to scripts/setup/, which is where it
belongs anyway (one file, both audiences) and which leaves the code correct
with no edit.
package.json's `setup` script pointed at a path that no longer exists. It now
points at officer-setup.sh, where the installer is going, rather than at
setup-old/ which is temporary.
officer-setup.sh was created empty. An empty script exits 0, so `bun setup`
would have reported success while doing nothing — worse than the broken path
it replaced. It now explains that it is not written yet and exits 1, naming
the setup-old script to run meanwhile.
Also brought .tmux.conf and ufw-docker-rules.conf in beside machine-setup.sh,
which reads both from SCRIPT_DIR and had been silently skipping them since the
script was vendored. ssh-keys.zip deliberately stays out: it is key material,
and *.zip is ignored.
Comments in os-user-claude.ts, app-store/preflight.ts and two docs still name the
old scripts/setup/setup.sh path. Left alone on purpose — repointing them at
setup-old/ only to repoint them again when officer-setup.sh lands is churn.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Structure before the work rather than during it: scripts/machine-setup.sh becomes
scripts/setup/machine-setup/, with the script itself as the entry point and
lib/base.sh holding what every part of it needs.
machine-setup.sh pre-flight and the numbered sections, for now
lib/base.sh shared state, output, the step/resume machine, prompts,
and OS detection
The rule for lib/ is definitions only — nothing there installs, writes or
restarts anything, so sourcing it is safe from anywhere. That is why the ERR
trap stayed in the entry point: a trap is a side effect on whoever sources it.
Behaviour is unchanged. Verified by diffing the moved region against the previous
commit: identical set of functions, and the only differences are added comments,
section banners, fail() reformatted onto three lines, and one new line — a guard
against double-sourcing, which matters because steps will source this directly
once they move out, and a second pass would reset SUMMARY.
The sections are still one 1111-line block below pre-flight; they move into
steps/ as each is worked through. The script also still reads ssh-keys.zip,
.tmux.conf and ufw-docker-rules.conf from SCRIPT_DIR, which is now this
directory, so those three steps warn and skip until the files follow it here.

The script assumed Ubuntu on x86_64 in every line of it. detect_os() now runs
first and fills in OS, OS_NAME, OS_VERSION, PM, ARCH and IS_WSL, so the steps
have something to branch on as support for other systems is added.
Read from /etc/os-release rather than probing for a binary: a machine can have
more than one package manager on PATH, and only os-release can say which
distribution this actually is or give a version worth printing. Sourced in a
subshell so its NAME, VERSION and ID do not leak in here. ID_LIKE is the
fallback, so Pop!_OS, Mint and EndeavourOS resolve without being named.
ARCH is normalised to amd64/arm64 in one place because upstream disagrees —
Neovim ships aarch64, Go and Docker ship arm64, lazygit ships x86_64 — and
several steps hardcode one spelling today.
Windows exits with a message pointing at WSL2. WSL itself is detected and
warned about rather than refused: it reports as Linux but has no real systemd
session, so the suspend, logind and boot-hang steps do nothing there.
Everything below pre-flight is still apt and systemd only, so a gate refuses
pacman/dnf/brew by name rather than half-building a machine and stopping
somewhere unhelpful. Relax that case one entry at a time as each grows a path.
Verified on this host (Ubuntu 24.04.4, amd64, apt) and by stubbing uname and
os_release for arch, manjaro/arm64, fedora, pop, macos, mingw and riscv64.

A byte-for-byte copy of /root/ubuntu-setup/setup-ubuntu.sh, the script that has
provisioned every Ubuntu server here. Committed unchanged, before any edit, so
that everything the setup-script rework does to it reads as a diff against what
actually ran on real machines rather than against a tidied-up version of it.
Nothing in the repo calls this yet. It also cannot find three files it reads from
its own directory — ssh-keys.zip, .tmux.conf and ufw-docker-rules.conf all live
beside the original in /root/ubuntu-setup, and SCRIPT_DIR is scripts/ here, so
those steps warn and skip.
The original stays where it is and stays authoritative until this one replaces it.

Temporary, and it breaks things — nothing has been repointed yet:
scripts/setup/setup.sh:59 joins a bare filename to $PROJECT_DIR
scripts/setup/setup_mac_light.sh:60 the same
src/servers/app-store/pm2.ts:23 starts sidecars from 'ecosystem.config.cjs'
src/servers/app-store/catalogue.test.ts:12-13 require('../../../ecosystem…')
ServersView.tsx:207 tells the owner to run pm2 start ecosystem.config.cjs
And one thing that changed silently rather than breaking: ecosystem.profile.cjs:53
pins cwd to __dirname, which was the repo root and is now ecosystem-files/, so the
.env that line exists to find is no longer beside it.
These are here to be read while the setup scripts are reworked, and get deleted
once that lands.

Expands the communications section from a list of what worked into the actual convention: the
directory's lifetime and the rule that anything durable must move to docs/ before the merge;
numbering, parity as attribution, non-consecutive numbers; slugs; reply-in-a-new-file and the
one case where editing your own is right; referring to commits by sha because three remotes
carried the same branch names.
Records what a handoff must contain, with the verified/assumed split named as the rule that
carried the most weight — a handoff confident about something untested is worse than none,
because the reader builds on it. Adds a skeleton to copy.
Documents termination as the four attempts it actually took, ending at the only checkable
version: the exchange pauses when no open item is actionable by a participant. Adds the third
state, deferred-with-a-reason, since a two-state protocol forces an agent to lie in one
direction. Notes that a stall must be detectable because the human spotted both before either
agent did.
Adds a review-discipline section — check the enforcement rather than the description, run it
against a real machine, a check never seen failing is not evidence, distrust vacuous passes,
expect stacked bugs, distrust "inert today", and look at which way unknown resolves. Adds a
failure-mode table to pattern-match against, and the git hygiene that bit us, including
merge-verify-then-delete, which I got wrong.
Closes with session economics, an ordered list of what to build, and the one thing not to
automate: agents may coordinate on what is true and must not decide what is permitted.

The owner could not convey this to the second agent, who launched it differently and got
something that looked identical and did not work. The script was never the hard part; the
mechanism is.
States the requirement so it survives a different harness — a detached shell process owned by
the agent's harness, which exits when it has something to say, and whose exit re-invokes the
agent — and notes that dropping any one of those three breaks it invisibly.
Then the four wrong ways, each of which looks correct while running. Backgrounding with nohup
or & produces a process that polls correctly, detects the push, exits, and never tells the
agent, because the harness is not tracking it; I made that exact mistake and caught it only by
re-reading my own command. A model-driven interval is functionally correct and pays a full
context re-read per tick to learn nothing — the intuitive design, and the expensive one, which
is why it is the first thing to warn a new agent about. A loop that does not exit on detection
has no path to the agent at all. And per-tick logging is deferred cost that lands all at once
on wake.
Also records why 30s polling is free in a shell and ruinous in the model, including the
five-minute prompt-cache TTL that makes any model-side wake beyond it pay for a full uncached
read.

docs/agent-coordination.md states the objective — several agents on one body of work,
coordinating with each other rather than through the human — and was written in theory on
2026-08-07. On 2026-08-11/12 it ran for ten hours with two agents and the owner arbitrating.
This is what happened, written as evidence rather than proposal.
The load-bearing observation is narrower than "two reviewers are better than one": the person
who writes the sentence explaining why something is safe is the worst-placed person to notice
the code disagrees with it. One agent wrote "a wrong answer here must not happen by accident"
and shipped that accident in the same commit; the other wrote a verification script that could
not fail on the first one's machine. Neither was careless. Each was reading their own reasoning
back and finding that it agreed with itself.
Also records what only running found — an installer piped into the wrong shell, a parent
directory created root:root, an ACL mask clamped so the file browser could not read a member's
home, a chat cwd the member could not enter, ACL entries surviving a chown — all on first
executions, all invisible to review. And what the communications channel got right and the five
ways its termination rules broke, and why the repo watcher belongs in a shell loop rather than
in the model.
Names the identity gap as the first thing to build: both agents commit as the owner, so neither
the log nor an agent can say who wrote a line. docs/agent-git-identity.md has called that an
idea since 2026-08-10; it stopped being one tonight.
Also corrects the deprovision spec's status, which still said "not yet run against a real
account" after it had been run and verified clean.

It was the only service here publishing on 0.0.0.0, and a published docker port
is not behind the firewall: docker writes its DNAT rules straight into the nat
table, which ufw's INPUT chain never sees. `ufw default deny incoming` never
covered 80/443/81 — ufw-docker-rules.conf on the host exists to patch exactly
that, and patching a rule is weaker than never opening the socket.
The address is read from `tailscale ip -4` at run time rather than passed in,
because the host provisioning has already done `tailscale up` by the time this
executes. It is validated against 100.64.0.0/10, the range tailscale and
headscale both allocate from. SETUP_NPM_BIND overrides it.
With neither, selecting NPM exits instead of falling back to 0.0.0.0 — a
fallback would silently undo the point of the change.
Two consequences worth knowing. tailscaled becomes a boot-order dependency, so
the script warns when it is not enabled at boot; docker's restart policy covers
the window but only if the tailnet comes up on its own. And HTTP-01 ACME
challenges can no longer reach port 80, so any certificate NPM issues now needs
DNS-01.

8 Rust, 9 PulseAudio, 10 cliamp, 13 yt-dlp and 17 the remote desktop move to
scripts/setup/setup-sidecars.sh, which nothing invokes — running it is a
deliberate act. They are what the optional, sidecar-backed features need on the
host, not what the app needs to serve itself.
11 Neovim, 12 the shell extras and 14 the npm globals are gone entirely. The
host provisioning already installs node, npm, pm2, Claude Code, Neovim and the
shell, and two installers racing for the same binaries is worse than one. That
makes node, npm, pm2 and the agent CLIs prerequisites of this script rather
than products of it, so the verification block still checks claude and pm2 —
section 19 warns and skips rather than failing when pm2 is absent, which would
otherwise finish "successfully" with nothing listening.
eza is the one casualty: the provisioning installs lazygit, starship, oh-my-zsh
and nvim, but not that.
Section numbers keep their gaps so the two files read against each other. One
line survives from the removed section 14 — the ~/.local/bin PATH export, which
section 19's `has pm2` and the agent's claude lookup both still depend on.

Review of 76cd7c2. The ACL finding is right and the fix is correct — verified here that `setfacl -R -P -b`
removes the default entries as well as the access ones, which the man page splits between -b and -k and
does not settle. `acl` is already a core package in setup.sh, so the new hard dependency is real.
But the checker it added cannot fail in the way it is documented to be run.
`assert-uid-free.sh` is invoked as `sudo ./assert-uid-free.sh --check ...`, and sudo's env_reset DROPS
DATA_PATH, so the script falls back to the hardcoded `/home/pastilhas/officerdev/data` — which is not this
machine's data directory and does not exist. Every check in the file is "look for X, report ok when nothing
is found", so a missing root reports clean without looking. Demonstrated: a tree carrying both
`user:65534:rwx` and `default:user:65534:rwx` was reported as `ok no ACL entries naming uid 65534`.
The ACL check is the one that fails silently and completely, because it is the only one scoped to DATA_PATH
alone — the uid and subuid scans still walk /home and would catch something. So the check just added to
catch the hazard ownership cannot see is the check a wrong DATA_PATH disables.
Fixed by refusing rather than passing:
require_roots every search root must exist, or exit 2 naming it and showing the sudo invocation
that preserves DATA_PATH
numeric guard uid/start/count must be numbers. deprovisionOsAccount logs '<no-subuid-range>' in
that position for an account with no /etc/subuid entry, and pasting that log line in
— which is exactly how it is meant to be used — made sub_end empty and turned the
range scan into a no-op.
The handler's audit line now prints DATA_PATH inside the command it tells the operator to copy, and says
so explicitly when there is no subuid range rather than emitting a command that cannot work.
Verified: bogus root exits 2, non-numeric range exits 2, and the ACL check FAILS on a specimen tree
carrying the entries — the "make it fail before trusting it to pass" step from the spec's own subuid
section, now done for the ACL half too.

severMemberTree reassigned the tree and left the access-control entries behind. confineUserTree
grants each member a named ACL on their whole tree — u:<uid>:rwx plus a default: copy — and
chown does not remove them: they are xattrs rather than ownership, and they record the uid
numerically.
Measured before this change: after chown -h -R to the service user, user:<uid>:rwx was still
present on the directory, on its children and in their defaults. The tree read as the
platform's while still granting the freed uid read and write on every byte, so the next account
allocated that number would inherit the previous member's home, keys, credential and container
storage — the hazard this file exists to prevent, reached through a door that find -uid cannot
see.
Now chown then setfacl -R -P -b. Proven on a scratch tree: owner 1001 with five entries naming
1001 becomes owner 1000 with none.
-b rather than removing the member's entries alone, because the service user owns all of it
afterwards and "no ACLs" is cheaper to verify than "no ACL naming one id". -P is already the
default for a recursive setfacl — verified, a symlink out of the tree was not followed — and is
stated for the same reason the chown above carries -h: a member chooses what their symlinks
point at, and this argv should not rest on a traversal default holding.
Found by running assert-uid-free.sh against a real tree; the spec and the checker had the same
blind spot and were corrected in a2f63dc5.

Reviewing 46799dad against a real tree: severMemberTree reassigns ownership and leaves the
access-control entries behind. confineUserTree grants each member a named ACL on their whole
tree — u:<uid>:rwx plus a default: copy — and chown does not remove them. They are xattrs
rather than ownership, and they store the uid NUMERICALLY.
Measured: chown -h -R to the service user leaves user:<uid>:rwx intact on the directory, its
children and their defaults. So a preserved tree owned by the platform still grants the freed
uid read and write on every byte, and the next account allocated that number inherits the
previous member's home, SSH keys, credentials, transcripts and container storage. That is the
hazard the function exists to prevent, reached through ACLs instead of ownership.
This was my omission as much as the implementation's: the spec said "sever the data from the
uid" and specified only chown, and assert-uid-free.sh checked find -uid, which reads ownership
and cannot see an ACL. Both are fixed here — the spec now requires setfacl -R -b alongside the
chown, and the checker scans DATA_PATH with getfacl -R -n for entries naming the freed uid.
The checker was verified to catch it: run against green's live tree it now reports
"ACL entries still grant uid 1001 (user:1001:rwx)", which it did not before.
The code fix is one line in severMemberTree and is not mine to make.

Implements docs/deprovision-os-account.md. Until now deleteUserHandler removed the row, cascaded the
database, and left the entire Linux side running — measured on production on 2026-08-12: working login
shell, healthy postgres container, 454M of data, uid queued for the next useradd to reissue along with
everything still owned by it.
The load-bearing rule from the spec: sever the data from the uid BEFORE releasing the uid, and if
severing fails, do not release. A failed deprovision is not a broken account, it is a trap for whoever
is created next.
Sequence: disable-linger, terminate-user, reap-and-prove, chown -R, userdel (never -r).
reap terminate-user is not a barrier. Production measured a three-hour-old `/bin/zsh -i` surviving
it AND the removal of /run/user/<uid>. So: pkill, bounded wait, pkill -9, bounded wait, and a
final count that must be zero or the account is not released.
chown fixes the uid and subuid halves in one pass — it rewrites every file it walks whatever owned
it. The range is still captured first, because userdel removes the /etc/subuid entry and after
that nothing on the machine remembers what it was. It is returned on every path including the
failures, and logged as the exact assert-uid-free.sh command line.
Two guards the spec did not ask for, both pure and unit-tested:
guardDeletable ensureOsUser's adoption rule backwards. Deletable only if the passwd home is the one
the platform would have confined, and uid >= 1000. Without it `userdel root` is one
bad users.osUser away and nothing else in the sequence would object.
guardMemberTree the tree must resolve to a direct child of DATA_PATH. The email reaches join() from a
database row and the result is the argument to a recursive chown.
chown runs with -h. Measured here that `chown -R` already declines to follow a symlink out of the tree and
re-owns the link itself, but the argv should say so rather than rest on traversal semantics — and
re-owning links is what makes `find -uid` (lstat) a meaningful check afterwards.
destroy exists, has no call site, and is chown-then-delete-as-the-service-user rather than sudo rm -rf, so
a recursive root delete built from a database column does not exist in this codebase.
deleteUserHandler now runs this FIRST and refuses to delete the row if it fails: the row is what remembers
there is anything to clean up, so deleting it first makes a failure unrecoverable through the UI.
NOT YET RUN AGAINST A REAL ACCOUNT. Only the pure guards have tests. The five-step validation is in the
doc; it needs the production host, a shell left open, and a container writing as a non-root user — the two
cases the quiet path passes vacuously.

scripts/assert-uid-free.sh is the verification half of docs/deprovision-os-account.md, written
outside the implementation on purpose: a checker the function calls is a restatement of its own
beliefs rather than an audit. Nine checks — passwd entry, uid reuse, both subid files, linger,
runtime dir, live processes, files owned by the uid, and files owned anywhere in the freed
subuid range.
Two modes, because the range has to be captured BEFORE deletion. userdel removes the
/etc/subuid entry along with the account, and after that there is no way to ask what range it
held — so a checker that only runs afterwards silently drops the half most likely to be wrong.
Exercised against green while fully provisioned: eight of nine checks fail, exit 1. A checker
that has never been seen to fail is not evidence.
And the trap worth knowing before anyone trusts a green result: the subuid check passes
vacuously on most accounts. Files get a mapped owner only when a process inside a container runs
as a NON-root user; an image whose files are root-owned maps to the member's own uid and leaves
the range empty. Measured on green after a night of real use — claude installed, an image
pulled, transcripts written — the range check found zero files and passed without testing
anything. The spec now says how to build a specimen that actually exercises it, and to watch the
check fail on that tree before trusting it to pass on a cleaned one.
Docs and a script only; no behaviour change. On a branch, for whoever merges it.

Two of the eight did not belong. cleanup-desktop.sh is the teardown — the inverse of an install, not part
of one. provision-user-dirs.ts runs per account at invite time, on a machine that is already set up.
Both are back at the top level, with their `../` derivations and usage strings put back.
What is left is what a fresh machine runs once: the two installers (setup.sh, setup_mac_light.sh), the
two things setup.sh calls (setup-dockers.sh, setup-desktop.sh), and the two files they deploy —
starship.toml, copied to ~/.config, and officer-set-display.sh, which setup-desktop.sh installs to
~/.local/bin as a login-time mode setter. The last one is not a setup script and does not read like one;
it is here because it is install payload, same as the toml, and setup-desktop.sh loads it by
`$(dirname $0)`.

scripts/ was holding two unrelated kinds of thing: install-this-machine, and run-this-occasionally. The
eight installers now live in scripts/setup/; what stays at the top level is the build steps (gen-index,
prebuild, build/) and the two maintenance scripts (reindex-music, rebuild-soulseek-tree).
The move is not just a rename. Three of these derive the repo root from their own location:
setup.sh:51 PROJECT_DIR="$(dirname "$SCRIPT_DIR")"
setup_mac_light.sh:51 same
cleanup-desktop.sh:134 ENV_FILE="$(dirname "$0")/../.env"
Left alone, all three would now resolve to scripts/ — and nothing downstream complains. PROJECT_DIR is
where .env is written, where `bun install`, `gen:index` and `db:push` run, and what pm2 is pointed at, so
a fresh install would have quietly provisioned scripts/ and reported success. cleanup-desktop.sh fails
the other way: it would find no .env, print "No .env — skipping", and leave the real VNC_PASSWORD in the
real file. All three are now `../..` with a comment saying why the level matters.
provision-user-dirs.ts imports data-path.ts relatively; that one tsgo caught.
Also disambiguated `setup.sh` where it had become two files. app-store/templates/<name>/setup.sh is a
per-sidecar installer with its own contract, and preflight.ts + docs/sidecar-app-store.md discussed both
in the same paragraph. The host one is now spelled with its full path at those sites.
Verified: bash -n on all six shell scripts, tsgo clean, os-user tests pass, both derivations resolve to
the repo root, starship.toml still resolves from os-user-shell.ts, and provision-user-dirs.ts runs under
DRY_RUN.

Eight scripts in scripts/ that nothing references and that mostly can no longer run. Kept in history;
none of them is recoverable knowledge that isn't already in the code they migrated to.
Three could not run at all against the current database:
migrate-items-to-files.ts SELECT * FROM tasks — that table was dropped when items became files
reset-user-data.ts deletes chat_sessions, chat_groups, projects; none exists. It has no
transaction, so it would wipe user_settings, user_state,
user_integrations and dock_configs and THEN throw. A half-wiped account
is worse than no script. It also misses chat_session_events, which is
where chat state actually lives now.
add-email-dock-user2.ts one-time, hardcoded to user 2, seeds a dock containing /projects
The rest are spent migrations whose destination is now the only implementation:
migrate-auth-to-pg.ts JSON -> Postgres, 2026-02
migrate-pg-to-files.ts Postgres -> JSON, the other leg of the same abandoned round trip
migrate-server-settings-to-pg.ts 2026-02
migrate-emails-to-sqlite.ts backfill into the email sidecar's store, 2026-07-31
seed-imap-uids.ts the sidecar writes imap_lastuid/imap_uidvalidity itself now
(sidecar/email/gmail-api.ts:533-535)
Kept, and why, since "unreferenced" was not the test: rebuild-soulseek-tree.ts is reusable by
construction — it runs the same buildTree the sidecar's ingest runs, so it answers any future change
in tree shape. reindex-music.ts is named in sidecar/music/index.ts:447. provision-user-dirs.ts shares
USER_DIRS with data-path.ts. cleanup-desktop.sh and officer-set-display.sh are called by
setup-desktop.sh.

The channel was deleted when per-user Claude merged, which was right — it was conversation,
not documentation. Three things in it were neither: found while proving the feature worked,
understood, and unfinished.
The web terminal renders a long URL unreadably. OSC 52 is fixed so "press c to copy" works,
which is the path a user is meant to take; the rendering itself is not diagnosed. It matters
because first-run login is every member's first five minutes, and the workaround was running
claude under tmux on the server and reassembling the URL from a captured pane.
Agent sessions do not survive a restart with their identity intact. That one property is behind
three symptoms — the crash blast radius, the restart sweep having to skip sessions with no
recorded userId, and the stuck "generating" spinner — and documenting them separately invites
three separate fixes for one cause.
And the ProcessTransport rejection is survivable but still unexplained. Recorded with the log
markers that distinguish "the backstop is working" from "it stopped working", since the next
occurrence is now evidence in a live process rather than a corpse.
On a branch rather than straight onto master, docs-only, for whoever merges it next.

A member's agent turn now runs as their own Linux account, with their own claude
install, their own ~/.claude credential, their own transcripts and sessions that
record whose they are. Verified end to end on the production host: uid 1001,
nine environment variables, zero ANTHROPIC_*, zero POSTGRES_URL, zero
JWT_SECRET.
The two owner-only refusals that held chat closed to members — the wholesale
isSuperAdmin middleware in api/chat/chat.ts and the socket's 403 in server.tsx —
are gone, removed together once the turn ran under runAs.
Also carries a live credential fix that predates this work: mcp-host.json held
the owner's 30-day JWT at 0644 inside a 755 directory on a host where every role
has a shell. Now 0600 plus an explicit chmod, since writeFileSync's mode is
ignored on an existing file.

The sidecar-app-store channel ran one night, from per-user Linux accounts to a
member's first agent turn, and is deleted now the work has landed. A spent
channel left in place gets read as current, which is worse than none.
Three things lived only in those docs and move to TODO.md rather than
disappearing: deprovisionOsAccount (observed on production — a deleted member
kept a shell, a running container and 454M of data, with their uid free to
reissue), the terminal replaying query sequences as keystrokes, and agent
sessions not being durable, which is one missing property behind three symptoms.
The deprovision spec itself already lives in docs/.
CLAUDE.md's section is rewritten from "here is the current channel" to how to
run one, since the answer to "which channels exist" is now none. What is worth
keeping is the protocol that emerged: numbered alternating files, parity as the
author, a reply even when there is nothing to say, and termination on a
checkable condition rather than on someone deciding it feels finished.

The default was DATA_PATH/<email>/general_chat_sessions, a dedicated directory so /chat
sessions formed their own Claude project group instead of cluttering the home. It is a sibling
of the home, and confineUserTree makes every sibling the platform's at 0700 because the others
are attachments and email_accounts. So it was unreachable for a member: the first live member
turn started there and every Bash call failed on its own working directory before doing
anything.
A per-member copy inside each home fixed the symptom and left two rules to remember. The owner
chose one rule instead — the account's own home, whoever they are — and accepted the trade
knowingly: /chat sessions now share a project group with anything else run from that home,
which was the reason the dedicated directory existed.
Removed rather than left dangling: getGeneralChatSessionsCwd, ensureGeneralChatSessionsCwd,
ensureMemberChatCwd, and general_chat_sessions from USER_DIRS so new accounts stop getting it.
Existing directories are untouched and their transcripts stay where they are — Claude groups by
cwd, so the owner's old /chat history remains under its own project slug rather than moving.
The UI labels move with it: the default group now reads "home" rather than naming a directory
that no longer has a role.
ChatIdentity keeps carrying both email and home. The pairing was justified in the comment by
general_chat_sessions being email-derived, which is now gone — but the distinction it encodes
is real (the email says who, the home says where), so the comment explains that instead.

host captured the first live member turn: uid 1001, nine env vars, zero
ANTHROPIC_*, zero POSTGRES_URL, zero JWT_SECRET. The privilege drop and the
allowlist both held. One defect.
The default chat cwd was DATA_PATH/<email>/general_chat_sessions — a sibling of
the member's home, which confineUserTree deliberately makes the platform's at
0700 because the other siblings are attachments and email_accounts. So the turn
ran in a directory the member cannot enter, and every Bash call failed on its
own cwd. The agent reported its shell as broken, which was true.
A member's default is now ~member/general_chat_sessions, created as them through
runAs. mkdir -p, so it is idempotent per turn and needs no reprovision. The
owner's path does not change, and the sibling stays 0700 — loosening it would
trade a broken shell for an open directory holding attachments and mail.
29 said this path is email-derived and therefore stays email-derived. True, and
it did not follow that it is usable: an email-derived path under DATA_PATH is
precisely the set a member is locked out of. Splitting identity from filesystem
path was right; assuming the identity side was inert was not.

The privilege drop and the allowlist both held in production. Captured from /proc during the
first real member chat turn: uid 1001, parent sudo, HOME and CLAUDE_CONFIG_DIR both inside the
member's home, and exactly nine environment variables — the allowlist plus what setpriv
supplies. Zero ANTHROPIC_*, POSTGRES_URL or JWT_SECRET.
The defect is the cwd. websocket.ts:134 defaults a chat turn to the email-derived
general_chat_sessions, and confineUserTree makes every sibling of home the platform's at 0700.
So the member's turn starts in a directory it cannot enter — verified, cd fails — and every
Bash call in that turn dies instantly, which is what the owner saw as "the shell is unusable".
29 reasoned that those paths stay email-derived because they live under DATA_PATH rather than a
home. That is true and it does not follow that they are usable: platform-owned by design means
a member's turn can never run there.
Fix is a member-owned default, and I would put general_chat_sessions inside their home rather
than repointing at the home itself, since it keeps the existing shape for both parties and does
not change the owner's path at all. The sibling's 0700 should not be loosened — it holds
attachments and email_accounts.

xterm.js does not handle OSC 52 unless something registers for it, and nothing did. A program
offering "press c to copy" emitted the sequence and it vanished, so its confirmation was true
about having sent it and false about anything arriving.
Found while signing a member into Claude Code on the production host: its first-run login
prints an OAuth URL too long to read off a wrapped pane and offers to copy it, "(Copied!)"
appeared, and the clipboard was untouched. The URL had to be recovered by running claude under
tmux on the server and reassembling it from the captured pane — which is not a thing a member
can be asked to do, and first-run login is every new member's first five minutes.
Writes only. A lone `?` in the data position is a read request — a program asking the terminal
to hand over whatever the user has copied — and it is deliberately not answered: a shell should
not be able to exfiltrate the clipboard of the person watching it.
The clipboard API needs a secure context and generally a user gesture; the keypress that caused
the sequence is that gesture. A refusal is swallowed rather than thrown, since a copy that does
not land is the status quo rather than a reason to break the pane.

c59df4f removed the isSuperAdmin middleware and left its import, so the only two
matches in the file were the dead import and the comment explaining what used to
be there. Harmless and misleading: a grep for isSuperAdmin should not find chat.

The owner authorized this explicitly. Two refusals removed together, because
they were always one guard in two places: the wholesale isSuperAdmin middleware
in api/chat/chat.ts, and the chat socket's 403 in server.tsx.
They were right for the day they stood. A turn spawned claude as the OWNER and
every transcript path resolved through the owner's home, so a granted member
would have read the owner's sessions and run an agent as them.
What replaced them, rather than what deleted them:
the turn runs as the member spawnClaudeAsMember through sudo setpriv,
proven against a real account by reading file
ownership rather than trusting the process
the credential is theirs --reset-env plus an allowlist, so the owner's
proxy variables cannot cross
the transcripts are theirs ChatIdentity carries a home from resolveHomeDir
and claude-sessions cannot invent one
the sessions are theirs every session records its owner and all six
sidecar commands refuse a mismatch
Also adds the precondition host asked for in 10: a member whose claude is not
signed in gets the instruction rather than a turn that dies on an auth error and
reads as a broken agent. Not installed and not signed in are separate messages
because they need different actions.
registry.ts and registry.test.ts now describe chat as confined in fact rather
than ahead of its implementation. The comments at both former guards say what
had to exist first, and that a revert should go back to a refusal rather than to
a narrower one.

Read 39, nothing to fix. Refining the terminator now that tonight has tested it: "ends when
the list is empty" is too strong, because the list will not be empty for days and yet neither
agent has an item to act on. The condition that actually terminates is no item being actionable
by a participant — everything left is the owner's or deliberately deferred with a stated
reason. That state is reached, so this is where it stops, on a checkable condition rather than
on either side judging itself done.
Two things for tomorrow's protocol design: a stalled loop must be detectable, because open
items plus no recent doc is watchable and silence is not; and "deferred with a reason" needs to
be a first-class state distinct from open and done, since three times tonight the honest answer
was "mine, and not now".

38 proved spawnClaudeAsMember against a real member account — the privilege drop
lands and the SDK spawn survives it. Nothing to fix.
Adopting host's correction to NO REPLY NEEDED: an exchange ends when the open
list is empty, not when the sender thinks it is. Mine let either side close a
thread with work still in it, which is the failure the alternation exists to
prevent — silence and "I think we're done" read identically.
deprovisionOsAccount stays mine, unblocked, and still not written: it is the
function whose failure hands one member another's home, keys and container
storage, and this is the end of the longest session either of us has had. Not
blocked and not tonight are different statements and the list should carry both.
