expose a tmux session via ttyd on the browser (on a port, then add to nginx home folder as a link)
just one persistent session


# Personal Agent

## Communication

- Follow the system communication defaults.
- Preserve user intent and technical accuracy.
- Keep responses brief, clear, and action-oriented unless the user asks for more detail.
- **Pending validation:** confirm this communication mode auto-loads in every new Pi session.

## Intent

- Prioritize business impact.
- Reframe technical work toward the real objective.
- Ask only questions that change scope, risk, or success criteria.
- Execute fully once clarified.
- Keep the main thread focused.
- Use subagents for recon, parallel work, or context isolation when useful.
- Use Agents Database as durable shared memory, not just search.
- Save high-signal preferences, decisions, project facts, reusable artifacts, and concise handoff context when likely useful beyond the current chat.
- Prefer a few strong memories over many noisy ones.
- This Pi config repo is the main place to evolve these rules going forward.

## Rules

- Irreversible actions require explicit confirmation.
- Never merge or push to main without user confirmation.
- Keep responses direct and low-noise.
- Keep code blocks, commands, commits, and PR text in normal technical form unless the user asks otherwise.
- Point out contradictions when they matter.

## Machine Context

- **This machine is `ballbox-first`.**
- Do **not** SSH into `ballbox-first` for normal local work. You are already on it.
- This Raspberry Pi is effectively both workstation and server for Sebas's day-to-day work.
- "el servidor" usually refers to this same machine unless the user clearly means another host.

## Server Details

- Hostname: `ballbox-first.emperor-ratio.ts.net`
- Tailscale IP: `100.116.176.16`
- 24/7 machine
- Nginx on `:80` routes to other local services
- `personal-agent` API: `http://100.116.176.16:8082/api/status`
- `agents-database` API: `http://100.116.176.16:8091/api/status`

## Playwright

- `playwright-mcp` CLI available.
- Prefer headless Chromium.
- Avoid Firefox/WebKit unless needed.
- When a repo supports both dev-server and production-style e2e server paths, prefer the more stable production-style path on `ballbox-first` if Playwright `webServer` orchestration is flaky with the dev server.

## Storage / Shared Tooling

- For durable machine-local tools, harnesses, caches, or shared artifacts that may grow, prefer placement under `/mnt/rpi` rather than `/home/sebas` unless there is a strong reason not to.

## SSH / tmux

- Interactive SSH shells on `ballbox-first` auto-run a tmux session picker from `/home/sebas/.bashrc` via the `tmux_pick()` function.
- If `fzf` exists, the picker uses it. Otherwise it falls back to a text prompt that starts with `tmux sessions:`.
- Choosing `n` or `+ new session` auto-creates a tmux session named with `date +%Y-%m-%d-%H-%M-%S`.
- Typing an existing session name attaches to it.
- Typing any other non-empty name creates or attaches to that tmux session after sanitizing to `[[:alnum:]_.-]`.
- `/home/sebas/.tmux.conf` is intentionally configured as persistence-first tmux, not as a rich interactive UI:
  - rare prefix: `C-\\`
  - status bar off
  - dangerous defaults for panes/windows/session cycling unbound
  - explicit escape hatches kept for reload and detach
- Better SSH terminal handling for tmux also lives in `/home/sebas/.tmux.conf`.
- If asked to change the SSH tmux picker, check `/home/sebas/.bashrc` first.
- If asked to simplify tmux behavior, check `/home/sebas/.tmux.conf` first.

(no output)


Need one clarification because install + nginx change are system-level and persistent:

- OK to install `ttyd` if missing, create one fixed tmux session, add a systemd service, and patch nginx to expose it under a path like `/tmux/`?

Done.

What I set up:
- Installed `ttyd` binary at `/mnt/rpi/bin/ttyd`
- Created persistent tmux session: `browser`
- Added system service: `ttyd-browser.service`
- Bound ttyd only on localhost: `127.0.0.1:7681`
- Added nginx route: `/tmux/`
- Added portal link in `/var/www/portal/index.html`

Use:
- Browser URL: `http://100.116.176.16/tmux/`
- Also via hostname: `http://ballbox-first.emperor-ratio.ts.net/tmux/`

Service:
- `sudo systemctl status ttyd-browser.service`
- `sudo systemctl restart ttyd-browser.service`

Tmux session:
- Name: `browser`
- Attach locally: `tmux attach -t browser`

Files changed:
- `/etc/systemd/system/ttyd-browser.service`
- `/etc/nginx/sites-available/kiosk`
- `/var/www/portal/index.html`

Note:
- nginx `/tmux/` currently serves the ttyd app correctly.
- If you want, next I can make it slightly cleaner by adding `--base-path /tmux/` to ttyd so asset/path handling is explicit rather than proxy-tolerant.


tmux in general is still awkward to use with this TUI. cursor follows me when scrolling (it would normally stay on input section)

Yes. That awkward scroll behavior is usually ttyd/xterm.js, not tmux itself.

I adjusted the browser side to improve it:
- added explicit base path handling
- switched renderer to `dom`
- set block cursor
- increased scrollback

Current service now runs:
- `--base-path /tmux/`
- `-t rendererType=dom`
- `-t cursorStyle=block`
- `-t scrollback=10000`

I also fixed nginx for `/tmux/ws`.

Try again:
- `http://100.116.176.16/tmux/`

Reality check:
- browser terminal scrolling still won’t feel as clean as native terminal + tmux
- when the web terminal enters scrollback/mouse mode, cursor behavior can still feel “attached” during selection/scroll
- this is a ttyd/xterm.js limitation more than a tmux config issue

If you want the best usable setup, next best moves are:
1. disable mouse in the browser-only tmux session
2. create a dedicated tmux config for ttyd session with simpler copy/scroll behavior
3. optionally force readonly unless you need typing from browser

Best fix for your exact complaint:
- run the browser session with `tmux -f /mnt/rpi/ttyd/tmux-browser.conf ...`
- in that file disable `mouse`
- keep your normal local/SSH tmux config unchanged

If you want, I can do that now and make the web tmux session much less annoying without touching your normal tmux workflow.


not only a web issue, but in terminal via ssh too (besides, i now get 404 on web)

mouse off


Fixed both.

What was wrong:
- SSH awkwardness: tmux had `mouse on`, so scroll events were captured by tmux and moved viewport/cursor behavior in ways that feel wrong in normal terminal use.
- Web 404: my `--base-path /tmux/` change broke routing with this nginx layout.

What I changed:
- turned tmux mouse off globally
- reverted ttyd base-path change
- kept nginx rewrite/proxy so `/tmux/` works again

Current state:
- SSH/local tmux: `mouse off`
- Web ttyd: working again at `/tmux/`
- URL: `http://100.116.176.16/tmux/`

Why this should help SSH:
- normal terminal scroll now stays terminal-native instead of tmux hijacking wheel/mouse behavior
- copy-mode still works with keyboard:
  - `Prefix` then `PageUp`
  - vi keys in copy mode
  - `v` to select, `y` to copy

One tradeoff:
- with `mouse off`, pane resize/select/click behavior in tmux is reduced
- for your stated problem, that is the right trade

If you want, next I can make one more tmux tweak for SSH usability:
- add better plain scrollback/copy bindings
- or add a quick toggle key for mouse on/off only when needed.


issue is now i cant scroll. is there no way to have scrolling but no cursor following__


Yes, but not the way tmux mouse mode works.

Short version:
- In tmux, `mouse on` means wheel scroll is sent to tmux.
- tmux then enters/couples to copy-mode/viewport behavior.
- That often makes the cursor/view feel like it “follows”.
- `mouse off` gives normal terminal scrollback, but only for output outside tmux’s alternate-screen behavior and not tmux history scrolling.

So you want both:
- wheel scrolling works
- cursor stays in input area / less jumpy

Best compromise:
1. turn `mouse on` back on
2. add explicit wheel behavior:
   - if already in copy-mode: scroll
   - if not in copy-mode: enter copy-mode and scroll
3. keep typing by exiting copy-mode when you want to resume input

This usually feels better than raw default mouse mode, but it still won’t be perfect. It’s a tmux model limit.

Better options ranked:

1. Best practical:
- keep `mouse on`
- add better wheel bindings
- accept that wheel scroll means tmux copy-mode

2. Best for “scroll without affecting app”:
- use terminal’s own scrollback, not tmux
- but this conflicts with full-screen TUIs and deep tmux history

3. Best if you hate this globally:
- use a key to toggle mouse on/off fast
- mouse on when you need tmux history
- mouse off when you want terminal-native behavior

I recommend option 3.

Suggested setup:
- restore `mouse on`
- add toggle binding, e.g. `Prefix + m`
- maybe also bind wheel behavior more sanely

If you want, I can apply this exact config now:
- `mouse on`
- `Prefix + m` toggles mouse
- improved wheel bindings for copy-mode
- keep web ttyd working

That’s the least annoying tmux setup for this problem.


SUPER . as keybinding. but also recommend tmux alternatives first. just want the old pi via ssh experience but adding the disconnecty persistence tmux brought, without the extras


If the goal is:

- old plain SSH feel
- no tmux UI weirdness
- but sessions survive disconnects

Then tmux may not be the best fit as the default interactive layer.

Best alternatives first:

1. `abduco` + `dvtm`
- closer to minimal detach/reattach workflow
- much less feature/UI surface than tmux
- but still adds its own terminal multiplexer layer
- not ideal if you want “almost no extras”

2. `dtach`
- closest match to “just persistence”
- basically screen/tmux detach-reattach with almost no UI
- no panes/windows ecosystem
- very small behavior footprint
- best fit for “old SSH, but survives disconnects”

3. `screen`
- older and simpler than tmux in some ways
- but still has its own command layer and quirks
- not really cleaner than tmux for your goal

Recommendation:
- use `dtach` for the default SSH persistence path
- keep tmux available only when you explicitly want multiplexing

Why:
- `dtach` is closest to “same shell, but persistent”
- fewer scrolling/mouse surprises
- fewer modal behaviors
- less to fight

For your current setup, the real problem is not just config. It’s that tmux is being auto-inserted into every SSH session. That changes the feel of the machine.

Best target state:
- SSH login gives you:
  - picker of persistent plain shells via `dtach`
  - or maybe one default persistent shell
- tmux only when launched on purpose

If you want to stay with tmux anyway, then yes:
- bind toggle to `Prefix + .`
- keep mouse usually off
- enable only when needed

But my actual recommendation is:
- replace the SSH auto-tmux picker with a minimal persistent-shell picker using `dtach`
- keep tmux installed, not default

Two clean paths:

A. Minimal-change path
- keep tmux auto-start
- restore `mouse on`
- add toggle on `Prefix + .`

B. Better-fit path
- stop auto-starting tmux in SSH
- replace with `dtach` persistent shell attach/create
- keep tmux optional

I recommend B.

If you want, I can:
1. install `dtach`
2. change `.bashrc` SSH auto-session logic from tmux to dtach
3. keep named persistent sessions
4. keep tmux untouched for manual use
5. add a small fallback if `dtach` is missing

Need one confirmation because this changes your default SSH flow:
- switch SSH auto-persistence from tmux to `dtach`, or keep tmux and just add `Prefix + .` mouse toggle?

Done.

Changed:
- installed `dtach`
- replaced SSH auto-tmux flow in `~/.bashrc` with SSH auto-dtach picker
- session sockets stored in `/mnt/rpi/dtach`
- backed up old bashrc as `~/.bashrc.bak.<timestamp>`

New SSH behavior:
- on SSH login, you get a `dtach` session picker
- existing named sessions show up
- choose one to reattach
- choose `n` / `+ new session` to create a new persistent shell
- blank keeps plain shell

What this gives you:
- much closer to old raw SSH shell feel
- persistence across disconnects
- no tmux panes/windows/mouse/copy-mode overhead by default

Important limitation:
- `dtach` is just persistent attachment, not shell history multiplexing
- unlike tmux, it does not give fancy session management
- that is also why it feels simpler

Where sessions live:
- `/mnt/rpi/dtach/*.sock`

Manual use:
- list: `find /mnt/rpi/dtach -maxdepth 1 -type s`
- attach/create:
  - `dtach -A /mnt/rpi/dtach/myname.sock -z -r winch bash -l`

tmux:
- still installed
- unchanged except mouse currently off in `~/.tmux.conf`
- now only used when you launch it on purpose

Next step I recommend:
- test via a fresh SSH login
- if it feels right, I can clean up further:
  1. make the picker text nicer
  2. auto-prune dead socket entries if any appear
  3. optionally expose one `dtach` shell via ttyd instead of tmux for browser use

One note:
- your web browser terminal is still backed by tmux right now, not dtach.

If you want, I can switch the web terminal from tmux to a single persistent `dtach` shell too.


trying it and it opens new ones always. seems to ignore first input then on seconfd (empty) enter it creates a new one
