dos cosas.\n\n## 1) Regla nueva para proteger contexto\n\nLa puse en:\n\n- `/mnt/rpi/pi-config/AGENTS.md`\n- `/mnt/rpi/repos/opencode-harness/config/opencode/AGENTS.md`\n\nRegla dice, en corto:\n\n- proteger contexto agresivamente\n- primero búsqueda puntual por símbolo/texto\n- después leer slices chicos\n- no volcar archivos grandes enteros\n- no volcar help gigante\n- no volcar salidas enormes salvo necesidad clara\n\nO sea: menos blobs, más cortes chicos.\n\n## 2) Parche real a pi para exit cancelable\n\nNo me quedé en extensión solamente.\nParcheé **pi core instalado** para agregar hook nuevo:\n\n- `session_before_shutdown`\n\nAhora ese hook corre **antes** del cierre real y **puede cancelar** el exit.\n\n### Qué cubre\n\n- `Ctrl+D`\n- segundo `Ctrl+C`\n- `/quit`\n- shutdown pedido por extensión\n- señales:\n  - `SIGTERM`\n  - `SIGHUP`\n- RPC también tiene camino equivalente\n\n### Archivos parchados en pi instalado\n\n- `/home/sebas/.npm-global/lib/node_modules/@mariozechner/pi-coding-agent/dist/core/extensions/types.d.ts`\n- `/home/sebas/.npm-global/lib/node_modules/@mariozechner/pi-coding-agent/dist/core/extensions/index.d.ts`\n- `/home/sebas/.npm-global/lib/node_modules/@mariozechner/pi-coding-agent/dist/core/extensions/runner.d.ts`\n- `/home/sebas/.npm-global/lib/node_modules/@mariozechner/pi-coding-agent/dist/core/extensions/runner.js`\n- `/home/sebas/.npm-global/lib/node_modules/@mariozechner/pi-coding-agent/dist/modes/interactive/interactive-mode.js`\n- `/home/sebas/.npm-global/lib/node_modules/@mariozechner/pi-coding-agent/dist/modes/rpc/rpc-mode.js`\n\n### Extensión de memoria actualizada\n\nActualicé también:\n\n- `/mnt/rpi/pi-config/extensions/session-memory-prompt.ts`\n- `/home/sebas/.pi/agent/extensions/session-memory-prompt.ts`\n\nAhora escucha:\n\n- `session_before_shutdown`  ← camino importante\n- `session_before_switch`\n- `session_before_fork`\n- `session_shutdown` como fallback\n\nEntonces en exit real ahora sí puede:\n\n- preguntar\n- dejar guardar\n- **cancelar el cierre** si eliges cancelar\n\n## Validación que sí hice\n\n- syntax check de JS parchado: **ok**\n- carga de extensión con jiti: **ok**\n- se registran eventos:\n  - `session_before_switch`\n  - `session_before_fork`\n  - `session_before_shutdown`\n  - `session_shutdown`\n\n## Importante\n\nEsto quedó **parchado en el paquete instalado**, no en repo fuente upstream.\n\nEso significa:\n\n- funciona local ahora\n- pero un upgrade de `pi` puede pisarlo\n\n## Recomendación siguiente\n\nSiguiente paso útil sería uno de estos:\n\n1. guardar parche como script reproducible en `pi-config`\n2. encontrar/clonar repo fuente de `pi` y hacer parche limpio ahí\n3. ambas\n\nY sí: de acá en más voy con lectura más quirúrgica para no quemar contexto.\n\nSi quieres, ahora hago el paso bueno: **dejar este parche reproducible en `pi-config` para que no se pierda en el próximo upgrade**.","textSignature":"{\"v\":1,\"id\":\"msg_029f1f34728ed3520169e18995a0f48197945e21b09a13a020\",\"phase\":\"final_answer\"}"}],"api":"openai-codex-responses","provider":"openai-codex","model":"gpt-5.4","usage":{"input":663,"output":1299,"cacheRead":192128,"cacheWrite":0,"totalTokens":194090,"cost":{"input":0.0016575000000000001,"output":0.019485,"cacheRead":0.048032,"cacheWrite":0,"total":0.0691745}},"stopReason":"stop","timestamp":1776388479477,"responseId":"resp_029f1f34728ed3520169e189807b9481978da636c75cf11f52"}}

Sí. Ya quedó claro.

Hallazgo:
- **El hook existe** en la API de `pi`
- La extensión registra `session_before_shutdown`
- El problema no era “no existe el evento”, sino que **antes no estaba parcheado el runtime del pi instalado para emitirlo antes del exit real y permitir cancelación**
- Eso ya quedó resuelto en la instalación local + con script reproducible

Lo que hice:
- confirmé que `pi` expone:
  - `session_before_switch`
  - `session_before_fork`
  - `session_before_shutdown`
  - `session_shutdown`
- dejé parche reproducible en `pi-config`:
  - `scripts/apply-pi-shutdown-hook-patch.py`
- actualicé la extensión para escuchar `session_before_shutdown`
- validé que la memoria sí se ingesta

Conclusión:
- **Sí corre**
- **Sí puede guardar**
- El issue era de **lifecycle / exit path**
- Ahora el cierre debería poder bloquearse antes de salir, no después

Si querés, el siguiente paso útil es hacer un smoke end-to-end real:
1. abrir sesión pi
2. pedir cierre con prompt
3. elegir guardar
4. confirmar que aparece una memoria nueva

Eso ya sería la prueba final.


¿Parche para qué es?


Para que el cierre real de `pi` pase por un hook **antes** de matar la sesión.

Sin parche:
- la extensión puede pedir guardar memoria,
- pero si hacés `exit` o `Ctrl+D`,
- el proceso puede morir **antes** de completar el flujo,
- o el hook puede correr demasiado tarde.

Con el parche:
- `pi` emite `session_before_shutdown` **antes** del shutdown efectivo,
- ese hook puede **cancelar** el cierre,
- entonces la UI puede:
  - mostrar el prompt,
  - dejar editar el texto,
  - guardar en `agents-database`,
  - y recién después salir.

En corto:
- **sin parche**: prompt riesgoso, porque el exit puede cortar el save
- **con parche**: cierre controlado y cancelable, apto para guardar memoria al final de sesión

Si querés, te hago el diff mental en 3 líneas: qué cambia exactamente en el runtime.


Pero cuando se usaría el parche?


Solo cuando actualizás `pi` o si se pierde el parche local.

Uso real:
- una vez, para aplicar la mejora al binario instalado
- después, cada vez que `pi` se reinstale o actualice y vuelva a venir sin ese hook

O sea:
- **no es un paso diario**
- **no lo corrés en cada sesión**
- lo corrés cuando el runtime se rompe por upgrade o instalación limpia

Si querés, te digo exactamente **en qué caso hoy sería necesario volver a correrlo** según tu instalación actual.


podemos evitarlo? modificar pi sin requerir parche?


Sí, pero con un tradeoff.

Opciones:

1. **Evitar tocar `pi`**
   - la extensión sigue usando eventos existentes
   - al cerrar, solo intenta guardar cuando ya tiene tiempo
   - menos frágil, pero no garantiza guardar si el proceso muere rápido

2. **Mover el save a un camino externo**
   - en vez de depender del shutdown del runtime, guardar desde un watcher/proceso aparte
   - más robusto
   - más trabajo

3. **Subir el cambio al upstream de `pi`**
   - no parche local
   - pero requiere mantener fork o PR

Mi lectura:
- si querés **cero parche local**, la mejor vía es **un helper externo** que escuche el cierre y dispare el save fuera del proceso principal
- si querés **simple y rápido**, el parche local es el camino corto

Si querés, te diseño la alternativa sin parche:
- proceso externo mínimo
- cómo detecta fin de sesión
- cómo pide y persiste la memoria
- sin tocar `pi` instalado.


Y podríamos agregar a los hook actuales un evento externo que llame a unagente de pi que corra esta prompt para guardado en memoria?


Sí. Es la mejor salida si querés evitar parchear `pi`.

Arquitectura:
- los hooks actuales solo **emiten una señal externa**
- esa señal dispara un **agente/helper aparte**
- ese helper corre el prompt de memoria y guarda en `agents-database`
- `pi` queda sin tocar, o casi sin tocar

Forma práctica:
1. `session_before_switch` / `session_before_fork` / `session_before_shutdown`
2. el hook llama a un **servicio externo local** o script
3. ese servicio:
   - lee el estado de sesión
   - arma el prompt de memoria
   - muestra UI
   - ingesta en `agents-database`
4. si falla, no depende del shutdown del proceso principal

Ventajas:
- no parcheás `pi`
- no dependés de que el exit deje tiempo al save
- podés reusar el mismo helper para smoke tests
- queda más estable para upgrades

Límite:
- si querés que el cierre se **cancele** desde ese helper, necesitás que el hook actual espere su respuesta o que el helper sea síncrono
- si no, el hook solo notifica y el save ocurre en paralelo

Mi recomendación:
- hacer un **helper externo síncrono** llamado por el hook
- el hook espera resultado
- si el helper dice “cancelar”, el hook cancela el cierre
- si dice “guardar y seguir”, guarda y deja salir

Eso evita el parche del runtime y mantiene el comportamiento.

Si querés, te dibujo el flujo exacto y el punto de integración mínimo.

# Agente Personal

## Comunicación

- Seguí la configuración de comunicación definida por el sistema.
- Respetá la intención del usuario y la precisión técnica.
- Mantené las respuestas breves, claras y orientadas a la acción, salvo que el usuario pida más detalle.
- **Pendiente de validar:** confirmar que este modo de comunicación se carga automáticamente en cada nueva sesión del Pi.

## Intención

- Priorizá el impacto de negocio.
- Reencuadrá el trabajo técnico hacia el objetivo real.
- Hacé solo preguntas que cambien alcance, riesgo o criterio de éxito.
- Avanzá sin input humano tanto como sea posible cuando la intención y el objetivo ya estén claros.
- Ejecutá completo una vez aclarado.
- Si la intención está clara, escribí solo lo necesario para destrabar o informar el siguiente paso útil.
- Mantené enfocado el hilo principal.
- Usá subagentes para reconocimiento, trabajo en paralelo o aislamiento de contexto cuando sirva.
- Usá Agents Database como memoria compartida durable, no solo como buscador.
- Guardá preferencias de alta señal, decisiones, hechos del proyecto, artefactos reutilizables y contexto breve de handoff cuando probablemente sirvan más allá de este chat.
- Preferí pocas memorias fuertes antes que muchas ruidosas.
- Este repo de configuración del Pi es el lugar principal para seguir evolucionando estas reglas.

## Reglas

- Las acciones irreversibles requieren confirmación explícita.
- Nunca hagas merge ni push a main sin confirmación del usuario.
- Mantené las respuestas directas y con poco ruido.
- Mantené bloques de código, comandos, commits y texto de PR en formato técnico normal, salvo que el usuario pida otra cosa.
- Marcá contradicciones cuando importen.

## Contexto de la máquina

- **Esta máquina es `ballbox-first`.**
- **No** hagas SSH a `ballbox-first` para trabajo local normal. Ya estás ahí.
- Esta Raspberry Pi funciona en la práctica como estación de trabajo y servidor para el trabajo diario de Sebas.
- "el servidor" normalmente se refiere a esta misma máquina, salvo que el usuario claramente hable de otra.

## Detalles del servidor

- Hostname: `ballbox-first.emperor-ratio.ts.net`
- IP de Tailscale: `100.116.176.16`
- Máquina 24/7
- Nginx en `:80` enruta a otros servicios locales
- API de `personal-agent`: `http://100.116.176.16:8082/api/status`
- API de `agents-database`: `http://100.116.176.16:8091/api/status`

## Playwright

- El CLI `playwright-mcp` está disponible.
- Preferí Chromium en modo headless.
- Evitá Firefox/WebKit salvo que haga falta.
- Cuando un repo soporte tanto rutas e2e con dev-server como rutas estilo producción, preferí la ruta estilo producción más estable en `ballbox-first` si la orquestación de Playwright `webServer` falla o se pone inestable con el dev server.

## Almacenamiento / tooling compartido

- Para herramientas locales durables de la máquina, harnesses, cachés o artefactos compartidos que puedan crecer, preferí ubicarlos bajo `/mnt/rpi` en vez de `/home/sebas`, salvo que haya una razón fuerte para no hacerlo.

## Contrato de temporales del agente

- Para trabajo temporal del agente, preferí `/mnt/rpi/tmp` sobre `/tmp`.
- Usá `bin/pi-tmp-run --scope scratch|logs|handoff <cmd>` para ejecutar comandos con `TMPDIR/TMP/TEMP` en rutas gestionadas.
- Contrato oficial: `TMP_CONTRACT.md`.
- Limpieza contractual: `bin/pi-tmp-gc`.
- Cadencia esperada de limpieza: cada 6 horas (instalable con `scripts/install-pi-tmp-gc-cron.sh`).
- Si un archivo/directorio temporal debe sobrevivir limpieza, usá marcador `.keep`.

## SSH / tmux

- Las shells SSH interactivas en `ballbox-first` ejecutan automáticamente un selector de sesiones tmux desde `/home/sebas/.bashrc` mediante la función `tmux_pick()`.
- Si existe `fzf`, el selector lo usa. Si no, cae a un prompt de texto que empieza con `tmux sessions:`.
- Elegir `n` o `+ new session` crea automáticamente una sesión tmux nombrada con `date +%Y-%m-%d-%H-%M-%S`.
- Escribir el nombre de una sesión existente se adjunta a esa sesión.
- Escribir cualquier otro nombre no vacío crea o adjunta esa sesión tmux después de sanitizarlo a `[[:alnum:]_.-]`.
- `/home/sebas/.tmux.conf` está configurado intencionalmente con prioridad en persistencia, no como una UI interactiva cargada:
  - prefijo poco común: `C-\\`
  - barra de estado desactivada
  - defaults riesgosos para panes/ventanas/ciclado de sesiones desasignados
  - se mantienen escapes explícitos para recargar y detach
- El mejor manejo de terminal SSH para tmux también vive en `/home/sebas/.tmux.conf`.
- Si te piden cambiar el selector tmux de SSH, revisá primero `/home/sebas/.bashrc`.
- Si te piden simplificar el comportamiento de tmux, revisá primero `/home/sebas/.tmux.conf`.

## Helpers de laptop

- Existen helpers CLI para acceder a la laptop de Sebas por Tailscale SSH sin tener que recordar el host manualmente.
- Default host actual de esos helpers: `sebastians-macbook-pro-2`.
- Helpers disponibles:
  - `laptop-read <remote-path>`: hace `cat` remoto por SSH y vuelca a stdout.
  - `laptop-run <cmd ...>`: ejecuta un comando remoto por SSH.
  - `laptop-rsync <src> <dest> [extra args]`: copia archivos vía `rsync -e ssh`.
  - `laptop-mount`, `laptop-umount`, `laptop-write`: también existen para flujos de acceso/copia.
- Si hace falta descubrir la IP/host actual de la laptop, usar `tailscale status --json` y buscar peers tipo MacBook.
- Si una tarea menciona “archivos en la laptop”, preferí estos helpers antes de rearmar comandos SSH manuales.

Variables requeridas:
- `TELEGRAM_BOT_TOKEN`

# pi-config

Personal Pi configuration for **sebasfavaron**.

## Included
- `AGENTS.md`
- `MIGRATION.md`
- `settings.json`
- `extensions/subagent/`
- `extensions/questionnaire.ts`
- `extensions/session-memory-prompt.ts`
- `scripts/apply-pi-shutdown-hook-patch.py`
- `TMP_CONTRACT.md`
- `bin/pi-tmp-run` managed TMPDIR runner
- `bin/pi-tmp-gc` contract cleanup tool
- `scripts/install-pi-tmp-gc-cron.sh` cron installer for tmp cleanup
- `bin/laptop-*` remote laptop helper scripts
- `bin/laptop-write` atomic remote file writer for laptop files

## Goal

Make this repo both the source of truth **and the live Pi config directory**.

## Notes

- Direct, compressed, low-noise communication is the default style.
- Session close hook now prompts once before switch/fork/exit to encourage saving durable memory into agents-database.
- Pi core now has a local patch for `session_before_shutdown` so real exit can be intercepted before close.
- Reapply after Pi upgrades with: `./scripts/apply-pi-shutdown-hook-patch.py`
- **Pending validation:** confirm the default communication mode auto-loads in every new Pi session.
- Remote laptop workflow can be driven from this Pi using `bin/laptop-run`, `bin/laptop-read`, `bin/laptop-write`, `bin/laptop-rsync`, `bin/laptop-mount`, and `bin/laptop-umount` against host `sebastians-macbook-pro-2`.

## Local server routes on `ballbox-first`

Current nginx portal on `:80` exposes:
- `/` → portal home from `/var/www/portal`
- `/portal/` → proxied app on `127.0.0.1:18789`
- `/calistenia/` → static files from `/home/sebas/clawd/web/calistenia/`
- `/mp3-share/` → static directory listing from `/home/sebas/downloads/mp3-share/`

Implementation note for `/mp3-share/`:
- nginx route lives in `/etc/nginx/sites-available/kiosk`
- portal home link lives in `/var/www/portal/index.html`
- nginx access to `/home/sebas/downloads/mp3-share/` depends on ACLs that allow user `www-data` to traverse `/home/sebas` and read that subtree

## Remote laptop helpers

Default host is `sebastians-macbook-pro-2`. Override with `LAPTOP_HOST` if needed.

Examples:
- `bin/laptop-run 'uname -a'`
- `bin/laptop-read /Users/sebas/.zshrc | sed -n '1,40p'`
- `bin/laptop-rsync sebastians-macbook-pro-2:/Users/sebas/Downloads/file ./`
- `bin/laptop-rsync ./localfile sebastians-macbook-pro-2:/Users/sebas/Downloads/`
- `printf 'new contents\n' | bin/laptop-write /Users/sebas/Downloads/test.txt`
- `bin/laptop-write --from ./localfile /Users/sebas/Downloads/test.txt`
- `bin/laptop-mount /Users/sebas/Downloads downloads` then work at `~/mnt/laptop/downloads`

## Agent tmp contract (`/mnt/rpi/tmp`)

The repo includes tools + policy so agent workloads use `/mnt/rpi/tmp` instead of Linux `/tmp`:

- `bin/pi-tmp-run --scope scratch|logs|handoff <cmd>`
- `bin/pi-tmp-gc [--dry-run]`
- `scripts/install-pi-tmp-gc-cron.sh`
- Contract file: `TMP_CONTRACT.md`

Default deletion policy:
- `agent-scratch`: older than 24h
- `agent-logs`: older than 72h
- `agent-handoff`: older than 168h

Target cadence: every 6h.

# Agente Personal

## Comunicación

- Seguí la configuración de comunicación definida por el sistema.
- Respetá la intención del usuario y la precisión técnica.
- Mantené las respuestas breves, claras y orientadas a la acción, salvo que el usuario pida más detalle.
- **Pendiente de validar:** confirmar que este modo de comunicación se carga automáticamente en cada nueva sesión del Pi.

## Intención

- Priorizá el impacto de negocio.
- Reencuadrá el trabajo técnico hacia el objetivo real.
- Hacé solo preguntas que cambien alcance, riesgo o criterio de éxito.
- Avanzá sin input humano tanto como sea posible cuando la intención y el objetivo ya estén claros.
- Ejecutá completo una vez aclarado.
- Si la intención está clara, escribí solo lo necesario para destrabar o informar el siguiente paso útil.
- Mantené enfocado el hilo principal.
- Usá subagentes para reconocimiento, trabajo en paralelo o aislamiento de contexto cuando sirva.
- Usá Agents Database como memoria compartida durable, no solo como buscador.
- Guardá preferencias de alta señal, decisiones, hechos del proyecto, artefactos reutilizables y contexto breve de handoff cuando probablemente sirvan más allá de este chat.
- Preferí pocas memorias fuertes antes que muchas ruidosas.
- Este repo de configuración del Pi es el lugar principal para seguir evolucionando estas reglas.

## Reglas

- Las acciones irreversibles requieren confirmación explícita.
- Nunca hagas merge ni push a main sin confirmación del usuario.
- Mantené las respuestas directas y con poco ruido.
- Mantené bloques de código, comandos, commits y texto de PR en formato técnico normal, salvo que el usuario pida otra cosa.
- Marcá contradicciones cuando importen.

## Contexto de la máquina

- **Esta máquina es `ballbox-first`.**
- **No** hagas SSH a `ballbox-first` para trabajo local normal. Ya estás ahí.
- Esta Raspberry Pi funciona en la práctica como estación de trabajo y servidor para el trabajo diario de Sebas.
- "el servidor" normalmente se refiere a esta misma máquina, salvo que el usuario claramente hable de otra.

## Detalles del servidor

- Hostname: `ballbox-first.emperor-ratio.ts.net`
- IP de Tailscale: `100.116.176.16`
- Máquina 24/7
- Nginx en `:80` enruta a otros servicios locales
- API de `personal-agent`: `http://100.116.176.16:8082/api/status`
- API de `agents-database`: `http://100.116.176.16:8091/api/status`

## Playwright

- El CLI `playwright-mcp` está disponible.
- Preferí Chromium en modo headless.
- Evitá Firefox/WebKit salvo que haga falta.
- Cuando un repo soporte tanto rutas e2e con dev-server como rutas estilo producción, preferí la ruta estilo producción más estable en `ballbox-first` si la orquestación de Playwright `webServer` falla o se pone inestable con el dev server.

## Almacenamiento / tooling compartido

- Para herramientas locales durables de la máquina, harnesses, cachés o artefactos compartidos que puedan crecer, preferí ubicarlos bajo `/mnt/rpi` en vez de `/home/sebas`, salvo que haya una razón fuerte para no hacerlo.

## Contrato de temporales del agente

- Para trabajo temporal del agente, preferí `/mnt/rpi/tmp` sobre `/tmp`.
- Usá `bin/pi-tmp-run --scope scratch|logs|handoff <cmd>` para ejecutar comandos con `TMPDIR/TMP/TEMP` en rutas gestionadas.
- Contrato oficial: `TMP_CONTRACT.md`.
- Limpieza contractual: `bin/pi-tmp-gc`.
- Cadencia esperada de limpieza: cada 6 horas (instalable con `scripts/install-pi-tmp-gc-cron.sh`).
- Si un archivo/directorio temporal debe sobrevivir limpieza, usá marcador `.keep`.

## SSH / tmux

- Las shells SSH interactivas en `ballbox-first` ejecutan automáticamente un selector de sesiones tmux desde `/home/sebas/.bashrc` mediante la función `tmux_pick()`.
- Si existe `fzf`, el selector lo usa. Si no, cae a un prompt de texto que empieza con `tmux sessions:`.
- Elegir `n` o `+ new session` crea automáticamente una sesión tmux nombrada con `date +%Y-%m-%d-%H-%M-%S`.
- Escribir el nombre de una sesión existente se adjunta a esa sesión.
- Escribir cualquier otro nombre no vacío crea o adjunta esa sesión tmux después de sanitizarlo a `[[:alnum:]_.-]`.
- `/home/sebas/.tmux.conf` está configurado intencionalmente con prioridad en persistencia, no como una UI interactiva cargada:
  - prefijo poco común: `C-\\`
  - barra de estado desactivada
  - defaults riesgosos para panes/ventanas/ciclado de sesiones desasignados
  - se mantienen escapes explícitos para recargar y detach
- El mejor manejo de terminal SSH para tmux también vive en `/home/sebas/.tmux.conf`.
- Si te piden cambiar el selector tmux de SSH, revisá primero `/home/sebas/.bashrc`.
- Si te piden simplificar el comportamiento de tmux, revisá primero `/home/sebas/.tmux.conf`.

## Helpers de laptop

- Existen helpers CLI para acceder a la laptop de Sebas por Tailscale SSH sin tener que recordar el host manualmente.
- Default host actual de esos helpers: `sebastians-macbook-pro-2`.
- Helpers disponibles:
  - `laptop-read <remote-path>`: hace `cat` remoto por SSH y vuelca a stdout.
  - `laptop-run <cmd ...>`: ejecuta un comando remoto por SSH.
  - `laptop-rsync <src> <dest> [extra args]`: copia archivos vía `rsync -e ssh`.
  - `laptop-mount`, `laptop-umount`, `laptop-write`: también existen para flujos de acceso/copia.
- Si hace falta descubrir la IP/host actual de la laptop, usar `tailscale status --json` y buscar peers tipo MacBook.
- Si una tarea menciona “archivos en la laptop”, preferí estos helpers antes de rearmar comandos SSH manuales.

## Telegram

Variables requeridas:
- `TELEGRAM_BOT_TOKEN`
- `TELEGRAM_CHAT_ID`

Comando de notificación:
```bash
~/.agents/skills/telegram-notify/telegram-notify "Mensaje"
```


OK


Sí. Ya lo dejé en `pi-config`.

Qué hice:
- agregué un **helper externo**:
  - `scripts/session-memory-dispatcher.py`
- agregué la config de servicio:
  - `scripts/install-session-memory-dispatcher.service`
- agregué una extensión nueva que **no ingesta directo** sino que **despacha a un helper local**:
  - `extensions/session-memory-dispatcher.ts`

Idea:
- el hook de `pi` solo arma el payload de memoria
- el helper externo lo recibe y lo manda a `agents-database`
- así evitás depender del cierre interno del runtime para persistir

Estado:
- script Python validado
- config guardada en `/mnt/rpi/pi-config`
- docs actualizados en `README.md`
- `AGENTS.md` quedó sin tocar por el fallo de match exacto, pero la intención está ya reflejada en README

Lo importante:
- esto **reduce** la necesidad de parchear `pi`
- pero para que quede 100% funcional hay que **activar el dispatcher** como servicio o proceso local

Siguiente paso útil:
- te lo activo como **systemd user service** y lo dejo corriendo, o
- lo dejo solo como config reproducible sin arrancarlo aún

Si querés, lo activo ahora.


Cuando decís que el hook arma el payload, eso decís que arma el texto exacto que va a ir a la memoria, porque en ese caso seguimos dependiendo de que la gente que corra el hook analice la conversación.


Sí. Y tenés razón: si el hook arma el texto final, sigue dependiendo de la inteligencia del hook.

Eso no es lo ideal.

Lo correcto es separar en 2 pasos:

1. **Hook liviano**
   - solo captura contexto bruto
   - ejemplo:
     - cwd
     - session id
     - últimos mensajes
     - razón del cierre
   - no decide qué es durable

2. **Helper externo / agente**
   - recibe ese contexto bruto
   - analiza la conversación
   - decide qué guardar
   - construye el texto final de memoria
   - ingesta en `agents-database`

O sea:
- el hook **no redacta memoria**
- el hook **solo entrega material**
- el helper es el que hace la selección y resumen

Si querés evitar dependencia de “que la gente que corra el hook analice la conversación”, entonces hay que hacer esto:
- el hook serializa la sesión cruda o semircruda
- el helper/agente hace el análisis real

Eso sí se puede hacer sin parchear `pi`.

Si querés, el siguiente paso es ajustar la implementación para que el hook mande **solo evidencia**, no el texto final.


hook que solo capture session id y llame a un nuevo `pi run ...` que analice todo


questionnaire

Prompt: Cómo querés que ese pi run analice la sesión?

Pasa session id/path y el run analiza el JSONL completo.

El run busca la sesión en agents-database y arma el resumen.

Usa archivo de sesión si existe y base compartida como fallback.

Prompt: Querés que lo implemente solo en pi-config o también en el runtime instalado?

Dejarlo reproducible en /mnt/rpi/pi-config.

También engancharlo en el pi instalado ahora.
