Startup commands: how office, project-reset and board decide the machine and the session

Host resolution order, the local-machine check, the address table, when the host is
remembered, why --host appears twice when starting from scratch, the three rebuild levels,
and the six traps that produced every startup fault so far.

## Update (2026-11-11 23:32:18)
## Rich discovery update (2026-11-11 23:32:18)
## What I did with sessions, plainly
A **session lives on a daemon, and a daemon runs on one machine**. A session is not "started in a directory" — the directory is where its *panes* run. That is the source of the confusion.
Tonight I created three sessions, none of them by restarting anything:
- `fresh-project-2026-11-11` — from `bin/office` adopting a test folder. I killed it during cleanup.
- `dryrun-alpha` — created by a bug: `--dry` still created the session. Fixed, then killed.
- `harness-repo` — not created yet; that is Test 2, which you have not run.
Your working session `paperclip-harness` was never restarted. `R` rebuilds its panes; it does not touch the sessions list.
**For your `email_agent` case**, the chain is:
1. The folder `/home/sam/paseo/projects/email_agent` is on `.13`.
2. The Paperclip project exists: **Email Agent**, id `b4edee39-…`, workspace `local_path` at that folder.
3. A session must live on `.13`'s daemon, because the panes run there.
From `.27`, the two ways:
**A — create the session from `.27`, then adopt on `.13`:**
```sh
# on .27, creates the session on .13's daemon and attaches you
tuios new --host nixos-desktop email-agent
# then, in a pane of that session (which runs on .13):
cd ~/paseo/projects/paperclip-harness
bin/office ~/paseo/projects/email_agent --project "Email Agent" --session email-agent --no-switch
```
`--no-switch` matters: it stops `office` from trying to create a second session, and it does not try to move your client.
**B — one command from `.27`, if ssh reaches `.13`:**
```sh
bin/office --remote 192.168.20.13 /home/sam/paseo/projects/email_agent --project "Email Agent" --session email-agent
```
`--remote` runs `office` on the other machine over ssh, so the session and its panes are created there. I added it tonight and it dry-ran on `.13`; from `.27` it needs your ssh key to be accepted (the attempt I made from `.13` to itself failed on ssh auth, which is expected for a self-connection).
Either way the last step is yours: TUIOS's session switcher, or `tuios attach --host nixos-desktop email-agent`. A program cannot move your client — the daemon refuses `switch-session` from a pane, and that refusal is correct.
## Test 3 — dry runs
Two changes are needed together: bump the lock, and rename the one home-manager option.
| | lock bumped | `initExtra` → `initContent` | dry-run build | Pi |
|---|---|---|---|---|
| `.13` | 2026-07-29 → 2026-11-07 | applied | **passes** | **1.5.0** |
| `.27` | same | applied | **fails**, eval error inside the new nixpkgs | 1.5.0 |
| `.51` | not yet done | not checked | — | 0.87.1 today |
So `.13` is ready to rebuild; `.27` needs its eval error looked at before it can go anywhere; `.51` would also need the bump to reach the same version. All of this was done in `/tmp/nixos-dryrun` copies — no system was touched and no lock was changed in `/etc/nixos`.
The `.13` rebuild, when you want it:
```sh
# in /etc/nixos: nix flake update nixpkgs home-manager
# then in home.nix: initExtra = -> initContent =
sudo nixos-rebuild switch --flake /etc/nixos#nixos-desktop
```
I can apply those two edits to `/etc/nixos` on `.13` now so the rebuild is one command, if you want. For `.27` I would rather find the eval error first — do you want me to chase it, or leave `.13` aligned and the other two where they are for now?

## Update (2026-11-11 23:32:18)
In the paperclip-harness repo (`gitea.lab.audasmedia.com.au/sam/paperclip-harness`), fixed a bug where `bin/office --dry` still created a TUIOS session (`dryrun-alpha`); dry run now prints intended actions (create project, write `<folder>/.harness/harness.toml`, create/reuse session and build eight panes) and writes nothing. Added `--remote <host>` to run office over ssh on another machine (dry-ran on `.13`; cross-host use needs ssh key trust). `bin/office` adopt behavior: writes only `<folder>/.harness/harness.toml`, never overwrites existing folders, adopts (never creates) an existing Paperclip project record, and remembers the machine so the flag is stated once. Committed as `9631cdd` (range 08a4b4e..9631cdd) on `main` and pushed to gitea.

## Update (2026-11-11 23:32:18)
When bumping nixpkgs/home-manager past the version in use (lock 2026-07-29 → 2026-11-07), the assertion fails: "The option definition `programs.zsh.initExtra' in `.../home.nix' no longer has any effect; please remove it. Use `programs.zsh.initContent` instead." The zsh block in /etc/nixos/home.nix (imported by flake.nix as `./home.nix`) at ~line 17 uses `initExtra = ''...''` containing PATH export, optional `~/.secrets` source, and p10k instant-prompt hook. Rename `initExtra` to `initContent` to fix. Confirmed 0 remaining occurrences after edit in dry-run copy.

## Update (2026-11-11 23:32:18)
After bumping flake.lock (nixpkgs, home-manager) and renaming zsh initExtra→initContent:
- `.13` (nixos-desktop): dry-run build PASSES; Pi 1.5.0. Ready to switch.
- `.27`: dry-run build FAILS with an eval error inside the new nixpkgs — `head` builtin called at nixpkgs lib/attrsets.nix:1711 (if length values == 1 || pred here (elemAt values 1) (head values)). Needs investigation before upgrading.
- `.51`: lock not yet bumped; still on Pi 0.87.1. Would need the bump to reach 1.5.0.
All tests done in `/tmp/nixos-dryrun` copies; no real system or `/etc/nixos` lock modified.

# Paperclip/TUIOS sessions across hosts, initExtra→initContent fix, and dry-runs
Sanitized discovery snapshot from the paperclip-harness turn.
Sessions model (TUIOS): a session lives on a daemon which runs on one machine; the session's working directory is where its panes run, not where the session is started. Created sessions tonight: `fresh-project-2026-11-11` (from `bin/office` adopting a test folder; killed during cleanup), `dryrun-alpha` (accidentally created by a bug where `--dry` still created the session; fixed, then killed), `harness-repo` (not created yet). The working session `paperclip-harness` was never restarted; `R` rebuilds panes only.
`email_agent` adoption recipe:
- Folder `/home/sam/paseo/projects/email_agent` is on host `.13` (nixos-desktop).
- Paperclip project "Email Agent" exists (id prefix `b4edee39-…`), workspace `local_path` at that folder.
- Session must live on `.13`'s daemon because panes run there.
- From `.27`: either (A) `tuios new --host nixos-desktop email-agent`, then in a pane: `cd ~/paseo/projects/paperclip-harness && bin/office ~/paseo/projects/email_agent --project "Email Agent" --session email-agent --no-switch` (`--no-switch` prevents a second session and client move); or (B) `bin/office --remote 192.168.20.13 /home/sam/paseo/projects/email_agent --project "Email Agent" --session email-agent` (requires ssh key trust; self-ssh from `.13` failed auth). Final step needs the user: TUIOS session switcher or `tuios attach --host nixos-desktop email-agent`. Daemon correctly refuses `switch-session` from a pane.
NixOS dry-run (Test 3) in `/tmp/nixos-dryrun` copies; no system or `/etc/nixos` lock changed:
- `.13`: lock 2026-07-29 → 2026-11-07, `programs.zsh.initExtra` → `initContent` in home.nix; dry-run build passes; Pi 1.5.0. Ready to rebuild: `nix flake update nixpkgs home-manager` then `sudo nixos-rebuild switch --flake /etc/nixos#nixos-desktop`.
- `.27`: lock bumped, initContent applied, dry-run build FAILS with eval error inside new nixpkgs.
- `.51`: lock not yet bumped; Pi 0.87.1 today.
The home.nix zsh block lives at `/nix/store/...-source/home.nix` (source `/etc/nixos/home.nix`), imported via `./home.nix` in flake.nix.

## Final answer snapshot
## What I did with sessions, plainly
A **session lives on a daemon, and a daemon runs on one machine**. A session is not "started in a directory" — the directory is where its *panes* run. That is the source of the confusion.
Tonight I created three sessions, none of them by restarting anything:
- `fresh-project-2026-11-11` — from `bin/office` adopting a test folder. I killed it during cleanup.
- `dryrun-alpha` — created by a bug: `--dry` still created the session. Fixed, then killed.
- `harness-repo` — not created yet; that is Test 2, which you have not run.
Your working session `paperclip-harness` was never restarted. `R` rebuilds its panes; it does not touch the sessions list.
**For your `email_agent` case**, the chain is:
1. The folder `/home/sam/paseo/projects/email_agent` is on `.13`.
2. The Paperclip project exists: **Email Agent**, id `b4edee39-…`, workspace `local_path` at that folder.
3. A session must live on `.13`'s daemon, because the panes run there.
From `.27`, the two ways:
**A — create the session from `.27`, then adopt on `.13`:**
```sh
# on .27, creates the session on .13's daemon and attaches you
tuios new --host nixos-desktop email-agent
# then, in a pane of that session (which runs on .13):
cd ~/paseo/projects/paperclip-harness
bin/office ~/paseo/projects/email_agent --project "Email Agent" --session email-agent --no-switch
```
`--no-switch` matters: it stops `office` from trying to create a second session, and it does not try to move your client.
**B — one command from `.27`, if ssh reaches `.13`:**
```sh
bin/office --remote 192.168.20.13 /home/sam/paseo/projects/email_agent --project "Email Agent" --session email-agent
```
`--remote` runs `office` on the other machine over ssh, so the session and its panes are created there. I added it tonight and it dry-ran on `.13`; from `.27` it needs your ssh key to be accepted (the attempt I made from `.13` to itself failed on ssh auth, which is expected for a self-connection).
Either way the last step is yours: TUIOS's session switcher, or `tuios attach --host nixos-desktop email-agent`. A program cannot move your client — the daemon refuses `switch-session` from a pane, and that refusal is correct.
## Test 3 — dry runs
Two changes are needed together: bump the lock, and rename the one home-manager option.
| | lock bumped | `initExtra` → `initContent` | dry-run build | Pi |
|---|---|---|---|---|
| `.13` | 2026-07-29 → 2026-11-07 | applied | **passes** | **1.5.0** |
| `.27` | same | applied | **fails**, eval error inside the new nixpkgs | 1.5.0 |
| `.51` | not yet done | not checked | — | 0.87.1 today |
So `.13` is ready to rebuild; `.27` needs its eval error looked at before it can go anywhere; `.51` would also need the bump to reach the same version. All of this was done in `/tmp/nixos-dryrun` copies — no system was touched and no lock was changed in `/etc/nixos`.
The `.13` rebuild, when you want it:
```sh
# in /etc/nixos: nix flake update nixpkgs home-manager
# then in home.nix: initExtra = -> initContent =
sudo nixos-rebuild switch --flake /etc/nixos#nixos-desktop
```
I can apply those two edits to `/etc/nixos` on `.13` now so the rebuild is one command, if you want. For `.27` I would rather find the eval error first — do you want me to chase it, or leave `.13` aligned and the other two where they are for now?
