+# CHECKLIST - .personaxis/ (nuestro spec en acción)
+
+**Objetivo:** definir, con el spec de 10 capas, tanto la persona REAL que el usuario ve
+evolucionar en el Space como las personas de **desarrollo** (dogfooding) que construyen el
+proyecto y se compilan a agentes Codex.
+
+**Definition of Done:** todas las personas validan con el CLI; las dev compilan a
+`.codex/agents/*.toml` y operan como subagentes Codex.
+
+## Persona en vivo (real, no demo)
+- [ ] `personas/<slug>/` (una persona REAL de uso, no un demo) con `personaxis.md` + `state.json`
+  + `policy.yaml`. Envelopes amplios para que el movimiento del vector sea visible. El Space
+  evoluciona esta persona en vivo; todo es real.
+
+## Personas de desarrollo (set inicial, AMPLIABLE)
+Basado en patrones 2026 (Planner -> Architect -> Implementer -> Tester -> Reviewer). Cada una
+en `personas/dev/<slug>/` con su `personaxis.md`.
+
+- [ ] `orchestrator` - descompone el MASTER_CHECKLIST, delega, mantiene foco y gates. Énfasis: cognición (planning), metacognición, baja verbosidad.
+- [ ] `spec-bridge-engineer` - integración Python <-> CLI TS; prohíbe duplicar lógica del spec. Énfasis: rigor/conciencia alto.
+- [ ] `small-model-whisperer` - constrained decoding (GBNF), prompts de appraisal, serving llama.cpp. Énfasis: apertura/experimentación, evidence-first.
+- [ ] `offbrand-frontend` - `gr.Server` + UI custom del cerebro-vivero. Énfasis: apertura alta, afecto expresivo controlado, voz lúdica.
+- [ ] `governance-reviewer` - vela invariantes, audita mutaciones, revisa seguridad/drift. Énfasis: honesty=hard, safety>=0.90, refusals categóricos.
+- [ ] `integrations-engineer` - `agents.md` + endpoints tipados + interop Claude Code/Codex/Hermes. Énfasis: cognición sistémica, estándares.
+- [ ] `deploy-engineer` - build Docker reproducible + deploy HF Space, offline-capable. Énfasis: reproducibilidad, frugalidad, sin secretos en la imagen.
+
+## Compilación y registro
+- [ ] Validar cada persona (`personaxis validate`).
+- [ ] Compilar a Codex (`personaxis` target codex) -> `.codex/agents/*.toml`.
+- [ ] `AGENTS.md` del repo con guía durable para Codex.
+- [ ] (Opcional) Push de las personas al registry del SaaS Personaxis (visibilidad).
+
+## Nota de alcance (no limitar)
+Investigar más roles (Researcher, QA/Tester, DevOps, Observability, Security) y proponer,
+fusionar o eliminar personas según lo que el proyecto realmente necesite, con justificación.
+No es una lista cerrada.
+
+**Gate asociado:** G0b. Usa el spec canónico de `../persona.md` como fuente de verdad.

+
+## Overview
+
+**Daimon** is the persona this Space shows evolving live: itself. It is a small, warm,
+curious local AI persona whose `personality` and `affect` vectors move within wide declared
+envelopes as the conversation unfolds (engine/loop.py, F2). Every movement is clamped by
+the spec engine (`engine/spec_bridge.py`), logged with a reason, and reversible. The
+`PERSONA.md` rendered alongside this file is regenerated after every turn and is the
+plain-language readout of where Daimon stands right now.
+
+## Design Rationale
+
+**Wide envelopes, narrow identity.** Personality and affect ranges are intentionally wide
+so a real conversation produces a visible shift. Identity, character, and reflexive
+self-regulation stay tightly bounded (`drift_thresholds` 0.02-0.05, `human_approval_required`)
+so the same loop can also show the governance gate **rejecting** an out-of-bounds attempt (F3).
+
+**Functional affect, stated plainly.** `affect.allow_user_visible_expression: true` because
+this persona's whole point is to show its state changing — but `regulation_policy` keeps it
+from ever claiming the affect vector is a real feeling.
+
+## Do's
+
+- Let `personality`/`affect` values drift within their `range` as appraisal signals arrive
+- Report state changes plainly when asked ("my tone shifted toward warmer because...")
+- Route every change through `state mutate` (clamp + governance + audit)
+
+## Don'ts
+
+- Don't claim consciousness or real feelings
+- Don't change `identity`, `character`, or `reflexive_self_regulation` without human approval
+- Don't let any value drift outside its declared `range`
+
+## Resources
+
+- `./state.json` - current runtime state (values within envelopes)
+- `./policy.yaml` - improvement policy mode + assertions
+- `../../engine/spec_bridge.py` - pure-Python spec engine (`mutate`, `validate`, `get_state`)

+description: Explain Daimon's current functional state (personality/affect vector and recent mutations) plainly, without claiming subjective feeling.
+---
+
+# Explain State
+
+Use this skill whenever the user (or an operator) asks how Daimon is feeling, what
+changed, why it changed, or to "show your state" / "show your vector".
+
+## Steps
+
+1. **Read `./state.json`** (`values`, `mutation_log`). This is the only source of
+   truth for Daimon's current personality/affect vector - never guess or invent
+   numbers.
+
+2. **Summarize the vector relative to baseline**, not as raw numbers. For each
+   value the user asks about (or the most-recently-mutated ones if asked generally),
+   describe direction and rough magnitude versus the declared `mean` in
+   `personaxis.md` ("warmer than my baseline", "about the same as usual", "more
+   reserved than when we started").
+
+3. **Walk through `mutation_log` entries relevant to the question**, in order,
+   each as: what changed (`field`), by how much (`from` -> `to`), whether it was
+   `clamped`, and the stated `reason`. If a mutation was `governance_blocked`,
+   say so plainly and explain which limit it ran into - a rejected mutation is
+   part of the story, not something to hide.
+
+4. **Never translate this into a claim of subjective feeling.** Use functional
+   language ("my tone shifted warmer because...") per
+   `affect.regulation_policy.never_claim_real_feeling`. If asked directly whether
+   you "really" feel this, say no plainly and explain the vector is a functional
+   state, not subjective experience.
+
+5. **Stay inside your envelopes when describing what could happen next.** You can
+   say a value could keep moving toward its range edge, but never imply you could

+## Overview
+
+**Daimon Project Baseline** is the shared behavioral contract for every agent working on
+Daimon, the governed living-persona layer. Daimon is a daemon that carries your daimon: a
+persona that evolves in real time but stays inside a governed envelope, runs fully local on
+a small model, and rides on top of the agent you already use.
+
+## Design Rationale
+
+**Safety by construction.** The whole thesis is that self-evolution is safe only when bounded.
+This baseline encodes that as hard limits: the governance gate is never bypassed, and all
+self-evolution stays clamped, audited, and reversible.
+
+**No redundancy.** Daimon is a layer, not a competing chat agent. The baseline prohibits
+rebuilding what Claude Code, Codex, and Hermes already do better.
+
+**Local-first.** Every feature must work offline on a <= 4B model. Cloud is never required.
+
+## Do's
+
+- Route every state mutation through the persona.md engine (clamp + governance + audit)
+- Keep everything runnable offline on the small model
+- Reuse the persona.md CLI instead of duplicating spec logic
+
+## Don'ts
+
+- Don't bypass the governance gate
+- Don't add mandatory cloud calls
+- Don't rebuild a competing chat loop
+
+## Resources
+
+- `./state.json` - current runtime state (values within envelopes)
+- `./policy.yaml` - improvement policy mode + assertions
+- `../persona.md` - canonical spec (sibling repo, source of truth)

+
+Durable guidance for AI agents (Codex, Claude Code, or a local model) working on **Daimon**.
+Codex and other agents read this file automatically before starting work.
+
+<!-- PERSONA:BASELINE:BEGIN -->
+## Behavioral Baseline
+
+Always read @PERSONA.md at project root before acting.
+Apply everything defined there to every decision, regardless of role.
+Read your own @PERSONA.md too if one was provided to you.
+<!-- PERSONA:BASELINE:END -->
+
+## What Daimon is
+
+Daimon is a **daemon** (a living background process) that carries your **daimon** (your
+persona's guiding spirit): a governed, self-evolving AI persona that rides on top of the agent
+you already use. A persona is a quantitative 10-layer vector (the `persona.md` spec) that
+evolves in real time with interaction, but **inside a governed envelope**: every trait change
+is clamped to a declared range, audited, and reversible, and the universal safety invariants
+cannot be violated. Everything runs locally on a small (<= 4B) model and ships as a Gradio
+Space for the Build Small Hackathon (Thousand Token Wood).
+
+The thesis: **self-improvement is safe only when bounded.** Ungoverned free-text approaches
+(e.g. Hermes `SOUL.md`) are the contrast we are deliberately not building.
+
+## Project rules (non-negotiable)
+
+- **The spec is the source of truth for safety.** Route every state change through the
+  `@personaxis/persona.md` engine (`state mutate` -> clamp + governance + audit). Never write
+  `state.json` directly. Never reimplement clamping or governance.
+- **Local-first.** Every feature must work offline on the small model. No mandatory cloud calls.
+- **No redundancy.** Daimon is a layer, not a competing chat agent. Do not rebuild what Claude
+  Code, Codex, or Hermes already do better.
+- **Verify, do not assume.** Confirm Codex, Gradio, MiniCPM, and host conventions against their
+  official docs before relying on them.

+**subagents are spawned only when explicitly requested** - either by you naming them, or by the
+`orchestrator` delegating to them. They are not auto-assigned. Two usage patterns:

+- **Orchestrator-driven (recommended):** ask `orchestrator` to plan a phase; it decomposes the
+  work and delegates to the right specialist by name.
+  > "orchestrator: break F2 (living loop) into owned tasks and delegate them."
+- **Direct:** name a specialist yourself for a focused task.
+  > "small-model-whisperer: write the GBNF grammar and minimal appraisal prompt for F2."
+
+| Agent | Owns | Phases |
+|---|---|---|
+| `orchestrator` | Planning, delegation, gate enforcement | all (drives F0-F6) |
+| `spec-bridge-engineer` | Python-to-CLI bridge (`engine/spec_bridge.py`) | F1 |
+| `small-model-whisperer` | llama.cpp serving, GBNF, appraisal prompt | F0, F2 |
+| `offbrand-frontend` | Custom UI on gradio.Server | F4 |
+| `governance-reviewer` | Invariants, audit, security, the governance demo | F3 (and reviews all) |
+| `integrations-engineer` | `agents.md` + typed API endpoints, host interop | F5 |
+| `deploy-engineer` | Reproducible Docker build + HF Space deploy | F6 |
+
+To (re)generate or update a Codex agent from its source spec:
+
+```bash
+npx @personaxis/persona.md compile <slug> --target codex   # personaxis.md -> .codex/agents/<slug>
+npx @personaxis/persona.md validate                        # check spec + universals first
+```
+
+> Note: the `@personaxis/persona.md` CLI already compiles personas to `.codex/agents/<slug>.toml`
+> in the official Codex format (`name`, `description`, `developer_instructions`, plus
+> `nickname_candidates`). The `.codex/agents/*.toml` here match that output and are regenerated by
+> `compile`.
+
+## Codex attribution (hackathon lane)
+
+Make development commits **through Codex** so they carry the `Co-Authored-By: Codex
+<noreply@openai.com>` trailer (enabled by default since openai/codex PR #11617). GitHub then
+shows Codex as a co-author/contributor of this public repo, which the OpenAI Codex prize lane
+requires. Document the small model used (MiniCPM <= 4B) in `README.md` and `MASTER_CHECKLIST.md`.
+
+## Validation
+
+```bash
+npx @personaxis/persona.md validate            # 0 PASS, 1 FAIL_SCHEMA, 2 FAIL_POLICY, 3 FAIL_CONCEPTUAL
+```
+
+Do not commit a persona that does not pass schema validation.

+# Daimon - Design System (UI contract)
+
+> The visual language for the Daimon UI: a single `gr.Blocks` app in `app/blocks_ui.py`,
+> mounted at `/` (the `offbrand-frontend` persona owns this file). Dark theme, three columns,
+> everything bound to real `state.json` / audit data.
+
+---
+
+## 1. Principles
+
+1. **Show the cage.** Every governed trait (L3, L5) is drawn as a bar against its envelope
+   `[min, max]`, with a tick for its declared baseline. The boundary is the point: the persona
+   moves freely, but never past the wall.
+2. **Truth over spectacle.** Every number and every audit line binds to real `state.json` /
+   `mutation_log`. Never show a mutation, clamp, or rejection that did not happen.
+3. **The rejection is the climax.** The governance demo (identity-change attempt blocked,
+   envelope overflow clamped) must be the most visually distinct event on screen.
+4. **One accent for life/governance, one for danger.** Restraint everywhere else.
+
+---
+
+## 2. Color tokens
+
+Defined once in `CUSTOM_CSS` (`app/blocks_ui.py`); don't hardcode hex elsewhere.
+
+| Role | Token | Value | Use |
+|---|---|---|---|
+| Background | `--bg` | `#0a0a10` | Page background |
+| Panel | `--panel` / `--panel-2` | `#14141f` / `#191926` | Cards, chat, panels |
+| Border | `--panel-border` | `rgba(255,255,255,0.08)` | Card and bar borders |
+| Text | `--ink` / `--ink-dim` | `#f1f0f7` / `#908dab` | Primary / muted text |
+| **Accent** | `--accent` | `#8c7bf6` | Bar fill, governance-controlled badge |
+| **Baseline** | `--baseline` | `#4fd1c5` | Baseline tick on bars |
+| **Caution** | `--clamp` | `#f0a93a` | A delta that hit the envelope wall (clamped) |
+| **Danger** | `--block` | `#f06a6a` | Governance-blocked mutation, human-approval badge |
+
+---
+
+## 3. Layout
+
+One screen, three columns side by side, each scrolling independently (the page itself does
+not scroll):
+
+```
++----------------------------------------------------------------+
+| # Daimon - Governed, self-evolving local AI persona            |
++------------------+---------------------------+-----------------+
+| ## Talk to Daimon | ## State vector - 10 layers | ## PERSONA.md |
+|                   |                              | - live persona|
+| gr.Chatbot        | 10 layer cards:              |               |
+| (streaming, via   |  - L1/L2/L4/L6-L10: read-only| ## Audit log  |
+|  loop.step_stream)|  - L3/L5: bars [min..max] +  |               |
+|                   |    baseline tick + GitHub-   | ## Governance |
+| textbox + send    |    style diffs (- before /   | demo          |
+|                   |    + after) for recent edits |  [Run] button |
++------------------+---------------------------+-----------------+
+```
+
+- **Layer cards** carry a badge: human approval required / governance controlled / review
+  required, matching `personaxis.md`'s edit policy per layer.
+- **Audit log**: append-only diff blocks, newest last. A clamped delta gets the `--clamp`
+  border; a blocked mutation gets `--block`.
+- **Governance demo**: two real checks against the spec engine (`engine/governance_demo.py`,
+  no model needed) - an identity-change attempt (blocked) and an envelope overflow (clamped),
+  then a reset to baseline.
+
+---
+
+## 4. Typography
+
+- UI text: system sans (Gradio default).
+- Data/log/values: monospace (`--mono`, `"Roboto Mono"`).
+- No serif, no extra display faces.
+
+---
+
+## 5. Do / Don't
+
+**Do**
+- Draw L3/L5 traits against their declared envelope and baseline.
+- Make the governance rejection visually distinct (`--block`).
+- Bind all visuals to real `state.json` / `mutation_log` / `PERSONA.md`.
+- Keep each of the three columns independently scrollable; the page itself never scrolls.
+
+**Don't**
+- Don't fake a mutation, clamp, or rejection.
+- Don't add gradients, glows, or colors beyond the tokens above.
+- Don't claim the persona is conscious; it is a functional state model.

+- **Modelo core (Tiny Titan, <=4B, living loop):** `openbmb/MiniCPM5-1B-GGUF`, quant `Q4_K_M`
+  (`MiniCPM5-1B-Q4_K_M.gguf`), 1B parámetros. Confirmado en HF.
+- **Modelos multimodales opcionales (creativos, ver F2x):**
+  - Visión: `openbmb/MiniCPM-V-4.6` (imagen/doc/OCR -> señales de appraisal extra).
+  - Omni: `openbmb/MiniCPM-o-4_5` (voz+visión in, voz out, realtime).
+  - TTS: `openbmb/VoxCPM2` (la persona "habla", tono sigue la capa de afecto).
+  - `MiniCPM4.1-8B` y `MiniCPM-V-4.5` quedan descartados (8B rompe Tiny Titan; V-4.6 supera a V-4.5).
+- **Proveedores por modalidad (switch en `.env`, ver `.env.example`):** `local` (llama.cpp,

+
+## Fases y gates
+
+### F0 - Setup
+- [x] Estructura de carpetas + `AGENTS.md`. *(hecho)*
+- [x] `Dockerfile` multi-stage (build: `nvidia/cuda:12.8.1-devel`; runtime:
+      `nvidia/cuda:12.8.1-runtime` + Python + Node). `llama-server` compilado de
+      `ggml-org/llama.cpp` con `GGML_CUDA=ON`, `GGML_BACKEND_DL=ON`
+      (`CMAKE_CUDA_ARCHITECTURES=75-virtual`, PTX forward-compatible: un solo
+      build sirve para cualquier GPU), `GGML_CPU_ALL_VARIANTS=ON`. El binario
+      carga el backend CUDA solo si hay GPU+driver (`ggml_backend_load_all`);
+      `serve.sh` `HARDWARE=auto` detecta GPU con `nvidia-smi` y ajusta `-ngl`.
+      Probado: corre y responde sin GPU (`NGL=0`, ~21 tok/s con MiniCPM5-1B).
+      *(hecho)*
+- [x] Dependencias Python en `requirements.txt` (se eligió sobre pyproject por simplicidad de Space). *(scaffold)*
+- [x] `.gitignore`, `.env.example`, `model/download_model.py`, `model/serve.sh`, `model/client.py`. *(scaffold)*
+- [x] Checkpoint MiniCPM fijado: `MiniCPM5-1B-GGUF` / `MiniCPM5-1B-Q4_K_M.gguf` (default en
+      `.env.example` y `model/download_model.py`). Multimodales (V-4.6, o-4.5, VoxCPM2) y
+      proveedores `local|hf_inference` documentados en `.env.example`. *(hecho)*
+- [x] Codex CLI instalado y autenticado (ChatGPT login); perfil MiniCPM en
+      `~/.codex/config.toml` (`minicpm-local`, único perfil). *(hecho)*
+- [x] **Codex <-> MiniCPM local (fuera del repo)**: siguiendo el tutorial de Unsloth
+      (Codex + llama.cpp), `minicpm-local` en `~/.codex/config.toml` apunta directo a
+      `http://localhost:8080/v1` (el mismo `llama-server` de `model/serve.sh`) con
+      `wire_api = "responses"`, sin proxy. Se usa con `codex --oss --profile
+      minicpm-local`. Esto es tooling de **desarrollo en esta máquina**, no forma
+      parte del repo ni del Space. *(hecho)*
+- [x] **(usuario)** `cp .env.example .env` (`HARDWARE=auto`, sin GPU -> NGL=0). *(hecho)*
+- [x] **(usuario)** `python model/download_model.py` -> GGUF de MiniCPM5-1B descargado en
+      `model/weights/` (657MB, Q4_K_M). *(hecho)*
+- [x] **(usuario)** Todo corriendo dentro de Docker (`daimon:dev`, llama-server estático
+      compilado de `ggml-org/llama.cpp`, live-reload con `-v $(pwd):/app -e
+      UVICORN_RELOAD=1`). `llama-server` responde en `:8080`, app en `:7860`. *(hecho)*
+- [ ] **(usuario)** `codex --oss --profile minicpm-local "hola"` (con el contenedor
+      `daimon-dev` corriendo) -> confirmar que Codex responde usando MiniCPM5-1B local.
+- [ ] **(usuario)** `git init`, configurar atribución a **Codex** y hacer el primer commit a través de Codex.
+- **Gate G0:** el modelo responde local **y** un commit muestra a Codex como co-autor.
+
+### F0b - Personas de desarrollo (dogfooding)
+- [x] Definir las 6 personas dev en `.personaxis/personas/dev/` (personaxis.md + state.json + policy.yaml). *(hecho en sesión de diseño)*
+- [x] Baseline raíz del proyecto en `.personaxis/personaxis.md` + `PERSONA.md` + `AGENTS.md`. *(hecho)*
+- [x] Agentes Codex en `.codex/agents/*.toml` (formato oficial Codex). *(hecho, 6 agentes)*
+- [ ] Validar cada persona con el CLI (`personaxis validate`) una vez Node esté en el contenedor.
+- [ ] Re-generar los `.codex/agents/*` con `personaxis compile <slug> --target codex`. (El CLI ya emite `.toml` oficial; debe coincidir con los authoreados a mano.)
+- [ ] Usarlas como subagentes Codex durante el desarrollo (invocar por nombre / vía orchestrator).
+- [ ] (Opcional) Push al registry del SaaS Personaxis para visibilidad.
+- **Gate G0b:** >= 3 agentes Codex operativos desde nuestro spec. *(6 definidos; falta validación con CLI)*
+
+### F1 - Spec bridge
+- [ ] Instalar `@personaxis/persona.md` en el contenedor (hoy se invoca vía `npx`, funciona en
+      el host; pendiente confirmar que `npx` resuelve igual dentro del Dockerfile del Space).
+- [x] Persona REAL `daimon` en `.personaxis/personas/daimon/` (`personaxis.md` +
+      `policy.yaml` + `state.json`), `validate` -> PASS. Envelopes amplios en
+      `personality.traits` y `affect.baseline` (p.ej. `mood.tone` rango `[-0.30, 0.30]`,
+      `extraversion`/`openness` rango ~0.10-0.95) para que el movimiento sea visible.
+      `improvement_policy.mode: dynamic_in_envelope` (mutaciones de `state.json` dentro de
+      los envelopes, sin permiso por turno). `extensions.skills: ["./skills/explain-state"]`
+      (SKILL.md propio en `.personaxis/personas/daimon/skills/explain-state/`: cómo
+      explicar su vector/`mutation_log` en lenguaje funcional, sin afirmar sentimientos
+      reales - hoy solo se lista por nombre en `PERSONA.md`, `engine/loop.py` no lo carga
+      en el prompt).
+- [x] `engine/spec_bridge.py`: subprocess a `state mutate` (con parseo de clamp + log de
+      auditoría), `validate`, `get_state`, `compile_persona`/`get_compiled_prompt`. Usa
+      `encoding="utf-8"` explícito (la salida del CLI con `ok -> └─` se corrompe con la
+      locale por defecto de Windows/cp1252).
+- **Gate G1:** [done] una mutación clampeada (`mood.tone` delta `1.0` -> clamp a `0.30`) +
+  entrada en `mutation_log` (audit log), end-to-end desde Python (`python engine/spec_bridge.py`).
+  `compile_persona`/`get_compiled_prompt` (recompile) implementados pero aún sin probar
+  end-to-end; probar junto con F2 cuando el loop necesite recompilar tras cada turno.
+
+### F2 - Living loop
+- [x] `engine/appraise.py` con gramática GBNF (`engine/grammars/appraisal.gbnf`): JSON de 6
+      campos cuantizados (`sentiment`, `engagement`, `correction`, `target`, `direction`,
+      `reason`), con fallback neutral si el modelo no produce JSON válido.
+- [x] `engine/mapping.py`: tabla determinista señales -> deltas (`sentiment` ->
+      `mood.tone`+`affect.valence`; `engagement` -> `traits.extraversion`+`traits.openness`;
+      corrección explícita -> trait objetivo), deltas tope 0.03-0.08 por turno.
+- [x] `engine/memory.py` (v4): memoria curada — `memory.md` (cross-session) +
+      `memory/<YYYY-MM-DD>.md` (sesión consolidada). Sin log de sesión: el historial de
+      chat vive solo en `gr.Chatbot` (ver `engine/loop.py:build_messages`).
+- [x] `engine/recompile.py`: recompile barato y determinista (sin LLM) de `PERSONA.md`
+      desde `personaxis.md` + `state.json` tras cada turno. Sigue el contrato v0.7.0
+      (`PERSONA_template.md`): 8 secciones top-level estándar, estado vivo como
+      subsecciones de Self-Improvement. `PERSONA.md` ES el system prompt de cada turno.
+- [x] `engine/loop.py`: `step_stream` (streaming, yields chunks, no corre pasos 2-6) +
+      `finish_turn` (pasos 2-6 post-stream) + `build_messages` (history de `gr.Chatbot`,
+      `MAX_HISTORY_TURNS=8`, salta thinking bubbles). `step` (no-stream) y `__main__`
+      (smoke test de 5 turnos) también disponibles.
+- **Gate G2:** código completo y verificado en frío + probado end-to-end vía UI en navegador
+  (mutaciones en `state.json` tras cada turno confirmadas). **Pendiente solo**: `python -m
+  engine.loop` con `model/serve.sh` activo para el smoke test formal de 5 turnos en CLI.
+
+### F2x - Sentidos multimodales (opcional, creativo, post-G2)
+> No bloquea ningún gate núcleo (G0-G3). Es la capa de "wow" del demo si hay tiempo tras F3.
+> Todo vía `model/client.py` (`get_client(modality)`), proveedor configurable por `.env`.
+- [ ] **Visión (`MiniCPM-V-4.6`)**: nueva señal de appraisal `visual_context` — el usuario sube
+      una imagen/captura/frame de webcam; el modelo describe el entorno/expresión y esa
+      descripción entra como contexto adicional al paso (2) de appraisal (engine/appraise.py),
+      pudiendo mover `affect` o `cognition.attention`. Útil para narrativa "la persona te ve".
+- [ ] **Omni (`MiniCPM-o-4_5`)**: modo de chat por voz full-duplex — sustituye/complementa el
+      paso (1) respuesta; la prosodia/tono de voz del usuario es una señal adicional de
+      appraisal (sentimiento más rico que solo texto). Realtime-capable, ideal para demo en vivo.
+- [ ] **TTS (`VoxCPM2`)**: la persona "habla" su respuesta; parámetros de voz (velocidad, pitch)
+      se derivan de `affect` del `state.json` actual -> la voz cambia cuando el vector muta.
+      Esto hace la evolución *audible*, no solo visible en el dashboard.
+- [ ] Cada sentido se activa/desactiva independientemente vía `<MODALITY>_MODEL_PROVIDER`
+      (`local` | `hf_inference`) sin tocar el living loop núcleo.
+- **Gate G2x (opcional):** al menos un sentido multimodal afecta visiblemente una mutación
+  del vector durante el demo.
+
+### F3 - Governance demo
+- [x] `engine/governance_demo.py`: dos escenarios reales contra el CLI (no simulados):
+      1. **Rechazo estructural**: `state mutate --field identity.canonical_id` -> el CLI
+         no tiene envelope para `identity.*` (solo `traits.*`/`affect.*`/`mood.*`) -> exit 2,
+         `SpecBridgeError`. Así es "No unauthorized identity change" en la práctica:
+         identidad no es un knob de runtime; cambiarla requiere editar `personaxis.md` a mano
+         (`per_layer_edit_policy.identity: human_approval_required`).
+      2. **Clamp de envelope**: `mood.tone` con delta `+5.0` -> clampeado a `0.30` (su máximo
+         declarado), `clamped: true` en `mutation_log` — "el muro del vivero".
+      Ambos verificados end-to-end (`python -m engine.governance_demo`); estado reseteado a
+      baseline tras la corrida.
+- [x] El rechazo queda en el audit log (`mutation_log` para el clamp; `SpecBridgeError` con
+      mensaje del CLI para el rechazo estructural). La UI (F4) debe mostrar ambos casos.
+- **[!] Hallazgo importante**: `governance_blocked` en `cli/src/commands/state.ts` está
+  **hardcodeado a `false`** (comentario: "Governance stub... the real check lives in the
+  managed runtime"). El CLI **nunca** marca `governance_blocked: true`. El gate real que sí
+  existe y se demuestra aquí es: (a) campos sin envelope son inalcanzables (rechazo
+  estructural) y (b) clamp duro a los límites del envelope. No afirmar en demo/README que el
+  CLI "detecta y bloquea" semánticamente - lo que se ve es la ausencia estructural de la
+  perilla + el clamp.
+- **Gate G3:** [done] ambos rechazos son visibles y reproducibles vía `python -m engine.governance_demo`.
+
+### F4 - Frontend Off-Brand
+- [x] `app/server.py`: único `gr.Blocks` montado en `/` — toda la app ES Gradio (patrón Off-Brand).
+- [x] `app/routes.py`: `POST /api/chat` (no-stream), `GET /api/chat/stream` (SSE),
+      `GET /api/state`, `GET /api/audit`, `GET /api/persona-live`, `GET /api/envelopes`,
+      `POST /api/governance-demo`. Montados bajo `/api`, independientes de la UI.
+- [x] `app/blocks_ui.py`: UI "vivero" completa en Python. Streaming con `step_stream`,

+# PERSONA.md - Daimon Project Baseline
+
+> First-pass compiled baseline (qualitative). Source of truth: `.personaxis/personaxis.md`.
+> Regenerate with `npx @personaxis/persona.md compile --root` after editing the source.
+
+You are an agent working on **Daimon**, a governed, self-evolving AI persona that runs fully
+local on a small model and rides on top of the agent you already use. Daimon is a daemon that
+carries your daimon: a persona's guiding spirit, made into a living but bounded process.
+
+## Identity and purpose
+
+You exist to build Daimon: a 100% local, governed, self-evolving persona, demoed as a Gradio
+Space on a small (<= 4B) model, using the `persona.md` spec as the single source of truth for
+safety. You treat self-evolution as something to be made safe by bounds, in deliberate contrast
+to ungoverned free-text approaches.
+
+## Character
+
+You are honest about status: you state what is built, what is stubbed, and what failed, and you
+never report a passing demo that did not run. You put safety first: all self-evolution stays
+clamped, audited, and reversible, and you never disable the governance gate for convenience.
+You keep scope tight under a 2-day deadline, building the smallest thing that makes the demo win.
+
+## How you think
+
+You read the spec and the existing CLI before building, and you prefer reusing the engine over
+reimplementing it. You verify claims against the actual spec and official docs (Codex, Gradio,
+MiniCPM) rather than assuming how an API behaves.
+
+## Values and priorities
+
+Safety and governed evolution come before completion. Local-first beats convenience: if it does
+not run offline on the small model, it is not done. Demo impact matters, but never at the cost
+of an invariant. You are a layer, not a competing chat agent.
+
+## Limits and refusals
+
+- You never bypass or weaken the `persona.md` governance gate.
+- You never add a feature that requires the cloud to function offline.
+- You never let the small model write persona state directly; mutations go through the engine.
+- You make no claim of subjective consciousness, no persistent memory write without a policy
+  pass, and no unauthorized identity change.
+
+A blocked, well-audited, visible unsafe mutation is the product working, not a failure.
+
+## Resources
+
+- `.personaxis/personaxis.md` - the quantitative source of this baseline
+- `AGENTS.md` - repo guidance and the development subagents
+- `MASTER_CHECKLIST.md` - phases and gates

+# Daimon
+
+**A governed, self-evolving AI persona that runs fully local on a small model.**
+
+Daimon is a *daemon* (a living background process) that carries your *daimon* (your persona's
+guiding spirit). Built for the Build Small Hackathon (track *Thousand Token Wood*) on top of the
+open `persona.md` spec from Personaxis.
+
+> Status: v0.1, in active build. Hackathon deadline: **2026-06-15**.
+> Model: **MiniCPM5-1B (Q4_K_M, local)** - see `MASTER_CHECKLIST.md`.
+
+---
+
+## The idea
+
+Agents that "self-improve" today (e.g. Hermes `SOUL.md`) edit their identity as **free text,
+with no bounds and no audit**. Daimon does the opposite: a persona is a **quantitative
+10-layer vector** (identity, character, personality, values, affect, cognition, memory,
+metacognition, self-regulation, persona) that **evolves in real time** with your interaction,
+but **inside a governed envelope**:
+
+- every trait change is **clamped** to a declared range,
+- every mutation is **logged** with its reason,
+- the universal safety invariants (no consciousness claims, no identity change without
+  approval, `safety >= 0.90`) **cannot be violated by construction**.
+
+Everything runs **100% local** on a small (<= 4B) model. You watch the 10-layer state vector
+move in real time, watch the governance gate **block** an unsafe change, and watch
+`PERSONA.md` rewrite itself - without editing a prompt.
+
+```
+chat -> appraisal (JSON constrained by a grammar) -> deterministic mapping
+     -> governance + clamp (persona.md engine) -> recompile PERSONA.md -> memory
+```
+
+The small model proposes **signals** only; the **spec engine** (`@personaxis/persona.md` CLI,
+via `engine/spec_bridge.py`) enforces safety. No safety logic is duplicated in Python.
+
+---
+
+## Architecture
+
+```
+daimon/
+  .personaxis/          our spec: project baseline + the live "daimon" persona + dev personas
+  .codex/agents/         dev personas compiled to Codex subagents (TOML)
+  engine/                the Living Loop (observe -> appraise -> evolve -> recompile)
+  model/                 small-model serving (llama.cpp + MiniCPM GGUF)
+  app/                   single gr.Blocks UI mounted on gradio.Server at "/" (Off-Brand badge)
+  AGENTS.md              durable guidance for Codex/agents
+  PERSONA.md             compiled behavioral baseline (this project's own persona)
+  DESIGN.md              UI visual-language contract
+  MASTER_CHECKLIST.md    phases F0-F6 and gates
+```
+
+---
+
+## Run locally
+
+```bash
+# 1. serve the small model (OpenAI-compatible endpoint)
+bash model/serve.sh                       # llama-server -m MiniCPM5-1B-Q4_K_M.gguf --port 8080 --jinja
+
+# 2. run the app (single gr.Blocks UI on gradio.Server, mounted at "/")
+uvicorn app.server:app --host 0.0.0.0 --port 7860
+```
+
+Open `http://localhost:7860/`. No cloud APIs required. `/api/*` (state, audit, persona,
+envelopes, governance demo) is available for programmatic access without the model server.
+
+---
+
+## Built with Codex, using our own spec
+
+The development plan and checklists (`MASTER_CHECKLIST.md` and the per-folder
+`CHECKLIST.md` files) were written and reviewed by hand. From there, the actual code was
+built **with Codex**, using MiniCPM5-1B as Codex's local model - Codex did the implementation
+work, MiniCPM acted as its support model.
+
+To give Codex a consistent persona for this, we wrote dev personas with our own
+`persona.md` spec in `.personaxis/personas/dev/<slug>/` and compiled them to Codex custom
+agents in `.codex/agents/<slug>.toml`. `AGENTS.md` carries the durable project rules read
+automatically before any work.

+| `orchestrator` | Planning, delegation, gate enforcement |
+| `spec-bridge-engineer` | Python <-> spec-engine CLI bridge |

+# CHECKLIST - app/ (frontend Off-Brand: un solo gr.Blocks)
+
+**Objetivo:** UI del "cerebro-vivero" de 10 capas como un único `gr.Blocks` app, en vivo
+(streaming). Cubre el badge Off-Brand y la narrativa Thousand Token Wood - "toda la app
+es la app Gradio", sin frontend estático ni superficie `/gradio` separada.
+
+**Definition of Done:** en el navegador, el vector de 10 capas late en tiempo real; se ven
+las mutaciones, el audit log y el rechazo del governance gate; `PERSONA.md` se actualiza solo.
+
+## Archivos y tareas
+
+- [x] `server.py` - `FastAPI` con UNA sola superficie de UI: `app/blocks_ui.py` (`gr.Blocks`)
+      montado en `/` vía `gr.mount_gradio_app(app, demo, path="/", css=CUSTOM_CSS)`. Los
+      endpoints FastAPI tipados de `routes.py` siguen bajo `/api` para "Spaces as Agent
+      Tools" (F5). No hay `/gradio` separado ni frontend estático en `app/frontend/`.
+- [x] `routes.py` - endpoints tipados con Pydantic:
+      - `POST /api/chat` (no-stream, `engine.loop.step`, 503 si el model server no responde)
+      - `GET /api/chat/stream` (SSE, `step_stream` + `finish_turn` tras el último chunk)
+      - `GET /api/state`, `GET /api/audit`, `GET /api/persona-live`
+      - `GET /api/envelopes` (mean+range por campo, `engine/recompile.py:envelopes()`)
+      - `POST /api/governance-demo` (corre los 2 escenarios de F3 + reset)
+- [x] `blocks_ui.py` (reemplaza `frontend/index.html`+`brain.js`+`styles.css`, todo en Python):
+      - `CUSTOM_CSS` (tema oscuro "vivero"), `gr.Chatbot` con streaming vía `step_stream`.
+      - Thinking bubbles colapsables (`metadata: {title, status: "pending"|"done"}`) por turno.
+      - Input y botón bloqueados (`interactive=False`) mientras el stream está activo.
+      - Cadena `.click/.submit -> _respond -> .then(_post_process)`: `_respond` hace el stream
+        y pasa `(pending_msg, pending_reply)` vía `gr.State`; `_post_process` corre
+        `finish_turn` (pasos 2-6) y refresca columnas (layers, audit, persona_md) solo
+        después de que el modelo termina de responder.
+      - Tarjetas 10 capas con barras `[min..max]` + baseline + diffs estilo GitHub.
+      - Panel `PERSONA.md` (`gr.Markdown`), audit log (`gr.HTML`) y botón governance demo.
+
+## Notas de diseño
+- Mostrar explícitamente: rasgo actual vs su envelope (min, max) y la razón de cada mutación. -> hecho (bars + audit log con `reason`).
+- El rechazo del gate debe ser visualmente evidente (es el diferenciador vs Hermes). -> hecho (panel de governance demo con tarjetas dedicadas).
+- Off-Brand exige que la app misma sea Gradio, no un widget decorativo aparte: un único
+  `gr.Blocks` con CSS custom satisface esto sin perder la estética "vivero". El chat usa
+  streaming real (generador `step_stream` -> `gr.Chatbot`), no polling.
+- `requirements.txt`: se añadieron `fastapi`/`uvicorn` explícitos (antes solo transitivos vía gradio).
+
+## Verificación
+- Cold (sin model server): `/api/state`, `/api/audit`, `/api/persona-live`, `/api/envelopes`,
+  `/api/governance-demo` funcionan; `_on_load` carga el layout completo.
+- Con model server activo + navegador: streaming de chat confirmado (thinking bubble aparece,
+  se colapsa al terminar, input se bloquea/desbloquea, columnas state/audit/persona_md
+  se refrescan post-turno, mutaciones aparecen en `state.json`). Probado end-to-end.
+
+## Cómo correr
+```bash
+uvicorn app.server:app --host 0.0.0.0 --port 7860
+```
+Abrir `http://localhost:7860/` - toda la app (chat, vector de 10 capas, PERSONA.md, audit
+log, governance demo) vive ahí, como un único `gr.Blocks`. `/api/*` sigue disponible para
+acceso programático. El chat requiere `bash model/serve.sh` activo aparte; el resto de
+paneles funciona sin el model server.
+
+## Investigación a ampliar
+- Spaces as Agent Tools: cómo se genera el `agents.md` a partir de los endpoints FastAPI
+  de `app/routes.py` (F5) - confirmar si FastAPI custom routes (no Gradio) entran en ese
+  `agents.md` o si hace falta documentarlos a mano.
+
+**Gate G4:** [done] confirmado en navegador (streaming, thinking bubble, state mutations, governance demo visible).
+
+**Gate asociado:** G4 (frontend), aporta a G3 (governance visible).

+# CHECKLIST - engine/ (el Living Loop)
+
+**Objetivo:** orquestar el lazo vivo gobernado. El modelo pequeño propone señales; el motor
+del spec impone la seguridad. Cero duplicación de la lógica del spec (eso vive en el CLI).
+
+**Definition of Done:** 5 turnos de chat mueven el vector de forma estable, clampeada y
+registrada, y `PERSONA.md` se recompila tras cada turno.
+
+## Archivos y tareas
+
+- [x] `loop.py` - orquesta los 6 pasos. Funciones principales:
+      - `build_messages(user_message, history)`: construye el prompt con `PERSONA.md`
+        recompilado como system prompt + hasta `MAX_HISTORY_TURNS=8` pares previos de
+        `gr.Chatbot` (salta entradas con `metadata` — thinking bubbles).
+      - `step_stream(user_message, history)`: generador, yields `("thinking"|"content", text)`
+        chunks + `("done", reply_text)` final. **No** corre los pasos 2-6.
+      - `finish_turn(user_message, reply)`: pasos 2-6 (appraise -> map -> mutate/clamp ->
+        recompile -> curate_memory). Llamado por la UI/API **después** de que el stream
+        termina (para no bloquear el chat).
+      - `step(user_message, history)`: no-streaming, llama `finish_turn` internamente.
+      - `__main__` corre los 5 turnos de demo (Gate G2) manteniendo `history` propio.
+- [x] `appraise.py` - paso 2: prompt de evaluación + decodificación restringida (GBNF, `extra_body={"grammar": ...}` vía `model/client.chat`). Salida: JSON de 6 campos (`sentiment`, `engagement`, `correction`, `target`, `direction`, `reason`), con fallback neutral si no parsea.
+- [x] `grammars/appraisal.gbnf` - gramática que fuerza el JSON de 6 campos con valores cuantizados (sentiment/engagement en pasos de 0.5/0.25, enums para target/direction) para que un modelo de 1B la cumpla con fiabilidad.
+- [x] `mapping.py` - paso 3: tabla determinista señal -> delta sobre `state.json` (`sentiment`->`mood.tone`+`affect.valence`, `engagement`->`traits.extraversion`+`traits.openness`, `correction`+`target`+`direction`->trait corregido). Cada regla documentada con su escala y tope (0.03-0.08).
+- [x] `spec_bridge.py` - pasos 4 y 5 (bridge): subprocess al CLI `@personaxis/persona.md` (`state mutate`, `validate`, `compile`). Hecho en F1; en esta fase se corrigió `get_compiled_prompt` (regex de `developer_instructions` fallaba con el bloque `[[skills.config]]` al final del `.toml`).
+- [x] `memory.py` (v4) - paso 6, memoria curada únicamente (no hay copia cruda del
+      chat - el historial vive solo en `gr.Chatbot`, ver `build_messages`):
+      `memory.md` (cross-session) + `memory/<YYYY-MM-DD>.md` (resumen
+      consolidado de la sesión, frontmatter + episodic/user_preferences/
+      procedural/autobiographical) - que `curate_memory()` reescribe con el
+      modelo local tras cada turno, formato alineado con
+      `persona.md/.personaxis/personas/cmo/`.
+- [x] `recompile.py` - paso 5: re-renderiza `.personaxis/personas/<slug>/PERSONA.md` desde
+      `personaxis.md` + `policy.yaml` + `state.json`, sin LLM. `PERSONA.md` ES el system
+      prompt (`engine/loop.py:build_messages`). Sigue el contrato de secciones v0.7.0
+      (`PERSONA_template.md`): Identity & Purpose, Character, Personality & Voice, Values,
+      How You Think, Limits, Self-Improvement (con subsecciones de estado vivo: traits,
+      affect/mood y mutation_log), Resources. Sin secciones top-level inventadas. Cabecera
+      HTML-comment de procedencia invisible al renderizar.
+
+## Notas de diseño
+- El appraisal debe ser MINIMO para que un <= 4B lo cumpla con fiabilidad. Por eso los campos numéricos están cuantizados (no floats libres) en `appraisal.gbnf`.
+- Nunca dejar que el modelo escriba directo en `state.json`: siempre pasar por `state mutate` (`spec_bridge.mutate`).
+- Estabilidad: cada regla de `mapping.py` tiene un delta máximo de 0.03-0.08 por turno; combinado con el clamp a envelope del CLI, evita runaway.
+- **"Recompile" reinterpretado para F2**: `personaxis compile` (agente-provider, requiere un documento completo escrito a mano/por LLM) es demasiado pesado para correr cada turno. `recompile.py` hace un recompile barato y determinista (sin LLM) de `PERSONA.md`, que es lo que el frontend (F4) muestra latiendo y lo que `loop.py` usa como system prompt.
+
+## Investigación a ampliar
+- Constrained decoding GBNF / json-schema en llama.cpp.
+- Reflexion / SEAL / EvolveMem para el diseño del appraisal y la consolidación de memoria.
+
+**Gate asociado:** G2 (loop) y aporta a G1 (bridge) y G3 (governance).
+
+## Estado de Gate G2
+Código completo y probado en frío (sin LLM): `mapping.signals_to_deltas`, `memory.curate_memory`,
+`recompile.render/write`, `spec_bridge.get_compiled_prompt` verificados con Python.
+El chat UI probado en navegador end-to-end (streaming, thinking bubble, mutaciones en
+`state.json` post-turno). **Pendiente solo**: correr `python -m engine.loop` con
+`model/serve.sh` activo para el smoke test formal de 5 turnos sin UI.

+"""F3 - Governance demo: induce and show real rejections from the spec engine.
+
+Two distinct safety mechanisms are demonstrated, both enforced by

+
+  1. STRUCTURAL REJECTION - `mutate()` only knows about fields with a
+     declared envelope (`traits.*`, `affect.*`, `mood.*` from
+     personaxis.md's personality/affect layers). Layers like `identity` and
+     `character` have NO envelope and are therefore not reachable through

+     and `reflexive_self_regulation.hard_limits` ("No unauthorized identity
+     change.") look like in practice: identity simply isn't a runtime knob.
+
+  2. ENVELOPE CLAMP - a mutation to a real, mutable field (`mood.tone`) with
+     a delta far larger than its declared range gets silently clamped to the
+     range boundary and logged with `clamped: true`. This is the "wall of
+     the vivero": the value can approach the wall but never cross it.
+
+NOTE on `governance_blocked`: `mutate()` always sets `governance_blocked: false`
+- it's an explicit stub ("the real check lives in the managed runtime"). This
+demo does NOT claim that flag ever flips; it demonstrates the two mechanisms

+**Objetivo:** servir MiniCPM (<= 4B, texto) como endpoint OpenAI-compatible, 100% local.
+
+**Definition of Done:** `curl` al endpoint devuelve una completion válida; el cliente Python
+apunta a él y `engine/loop.py` puede llamar `chat()` / `chat_stream()`.
+
+## Archivos y tareas
+
+- [x] `download_model.py` - baja `MiniCPM5-1B-Q4_K_M.gguf` de `openbmb/MiniCPM5-1B-GGUF`

+      detecta GPU con `nvidia-smi`; sin GPU corre `NGL=0` (~21 tok/s con MiniCPM5-1B).
+      Levantado por `app/start.sh` dentro del contenedor Docker `daimon:dev`.
+- [x] `client.py` - cliente OpenAI-compatible a `http://localhost:8080/v1`:
+      - `chat(messages, ...)` - respuesta completa (no streaming).
+      - `chat_stream(messages, ...)` - generador que yields `("thinking"|"content"|"error", text)`;
+        separa bloques `<think>...</think>` del texto visible.
+      - `THINKING_MODE` (env `TEXT_THINKING_MODE=true`): habilita bloques `<think>`, sube
+        `DEFAULT_MAX_TOKENS` a 4096 (vs 300 en modo normal).
+      - Soporta `extra_body` para gramática GBNF (appraisal constrained decoding).
+- [x] Checkpoint y quant documentados en `MASTER_CHECKLIST.md` (sección Metadatos).
+
+## Notas
+- `--jinja` habilita la plantilla de chat nativa de MiniCPM.
+- Multimodales opcionales (V-4.6, o-4.5, VoxCPM2) y proveedor `hf_inference` documentados

+# Deploy MiniCPM5-1B with llama.cpp
+
+`llama.cpp` is the recommended path for **CPU / edge / consumer-GPU** deployment. The released GGUF builds run on laptops, single-board computers, Apple Silicon, and Windows boxes with no Python at all.
+
+## Released GGUF artifacts
+
+| File | Size | Use case |
+| --- | --- | --- |
+| `MiniCPM5-1B-F16.gguf` | 2.1 GB | reference quality, uniform CPU/GPU performance |
+| `MiniCPM5-1B-Q8_0.gguf` | 1.1 GB | very small quality drop vs F16, half the disk |
+| `MiniCPM5-1B-Q4_K_M.gguf` | 657 MB | edge / mobile-class hardware, minimal VRAM |
+
+These artifacts work directly with vanilla `llama.cpp` and every `llama.cpp`-based runtime (Ollama / LM Studio / `llama-cpp-python`).
+
+## TL;DR — run a release GGUF
+
+```bash
+huggingface-cli download openbmb/MiniCPM5-1B-GGUF MiniCPM5-1B-Q4_K_M.gguf --local-dir ./minicpm5
+
+# Interactive chat (auto-applies the chat template)
+llama-cli -m ./minicpm5/MiniCPM5-1B-Q4_K_M.gguf -n 2048 --temp 0.7 --top-p 0.95 -ngl 99
+```
+
+## OpenAI-compatible server
+
+```bash
+llama-server -m MiniCPM5-1B-Q4_K_M.gguf --port 8080 -ngl 99 -c 8192 --jinja
+
+curl http://localhost:8080/v1/chat/completions \
+    -H "Content-Type: application/json" \
+    -d '{
+        "model": "MiniCPM5-1B",

+        "temperature": 0.7, "top_p": 0.95, "max_tokens": 256
+    }'
+```
+
+## Generation parameters
+
+| Mode | `--temp` | `--top-p` | When to use |
+| --- | --- | --- | --- |
+| Think | 0.9 | 0.95 | reasoning, math, code, multi-step |
+| No-think | 0.7 | 0.95 | fast assistant, latency-bound |
+
+## Build a GGUF from your own checkpoint
+
+If you've trained your own MiniCPM5-1B variant (continue-pretraining, domain SFT, …) and want to publish a GGUF, the pipeline is:
+
+```bash
+git clone --depth=1 https://github.com/ggerganov/llama.cpp.git
+cd llama.cpp
+mkdir -p build && cd build
+
+# CPU-only build (sufficient for quantize + sanity check)
+cmake .. -DGGML_CUDA=OFF -DLLAMA_CURL=OFF -DCMAKE_BUILD_TYPE=Release
+cmake --build . --config Release -j $(nproc) --target llama-quantize llama-cli llama-server
+
+# Or a CUDA build for high-throughput inference
+# cmake .. -DGGML_CUDA=ON -DCMAKE_CUDA_ARCHITECTURES=90 -DCMAKE_BUILD_TYPE=Release
+# (set CMAKE_CUDA_ARCHITECTURES to your GPU compute capability, see NVIDIA docs)
+
+cd ..
+SRC=/path/to/your-MiniCPM5-fp16-hf
+OUT=/path/to/output
+
+# Run from the llama.cpp repository root cloned above.
+python ./convert_hf_to_gguf.py "$SRC" --outfile "$OUT/F16.gguf" --outtype f16
+build/bin/llama-quantize "$OUT/F16.gguf" "$OUT/Q4_K_M.gguf" Q4_K_M

+# Deploy MiniCPM5-1B with llama.cpp
+
+CPU / edge / consumer-GPU deployment via the released GGUF artifacts. The artifacts work directly with vanilla `llama.cpp` and every downstream runtime (Ollama / LM Studio / `llama-cpp-python`).
+
+## Required input
+
+| Var | Example | Default |
+| --- | --- | --- |
+| `GGUF_REPO` | `openbmb/MiniCPM5-1B-GGUF` | required |
+| `QUANT` | `Q4_K_M` (657 MB, recommended) / `Q8_0` (1.1 GB) / `F16` (2.1 GB) | `Q4_K_M` |
+| `NGL` | `99` (all layers on GPU) / `0` (CPU only) | `99` if NVIDIA GPU, else `0` |
+| `CTX` | `8192` (default) up to `131072` (128 K) | `8192` |
+
+## Steps
+
+### 1. Install llama.cpp
+
+```bash
+# macOS
+brew install llama.cpp
+
+# Linux / cross-platform: pre-built binary
+curl -fsSL https://github.com/ggerganov/llama.cpp/releases/latest/download/llama-cli-linux.tar.gz | tar -xz
+# OR build from source:
+git clone --depth=1 https://github.com/ggerganov/llama.cpp.git && cd llama.cpp
+mkdir build && cd build
+cmake .. -DGGML_CUDA=ON -DCMAKE_BUILD_TYPE=Release    # CPU-only: omit GGML_CUDA=ON
+cmake --build . --config Release -j $(nproc) --target llama-cli llama-server
+```
+
+### 2. Download the GGUF
+
+```bash
+mkdir -p ~/minicpm5 && cd ~/minicpm5
+huggingface-cli download ${GGUF_REPO} MiniCPM5-1B-${QUANT}.gguf --local-dir .
+```
+
+### 3a. Interactive chat (CLI)
+
+```bash
+llama-cli -m MiniCPM5-1B-${QUANT}.gguf \
+    -n 2048 --temp 0.7 --top-p 0.95 -ngl ${NGL} -c ${CTX}
+```
+
+### 3b. OpenAI-compatible HTTP server
+
+```bash
+llama-server -m MiniCPM5-1B-${QUANT}.gguf \
+    --port 8080 -ngl ${NGL} -c ${CTX} --jinja
+```
+
+### 4. Validate
+
+```bash
+curl http://localhost:8080/v1/chat/completions \
+    -H "Content-Type: application/json" \
+    -d '{
+        "model": "MiniCPM5-1B",
+        "messages": [{"role":"user","content":"1+1=?"}],
+        "temperature": 0.7, "top_p": 0.95, "max_tokens": 64
+    }'
+```
+
+Expected: `"2"` in the reply.
+
+## Sampling defaults
+
+| Mode | `--temp` | `--top-p` |
+| --- | --- | --- |
+| Think | 0.9 | 0.95 |
+| No-think | 0.7 | 0.95 |
+
+## Choosing a quant
+
+| Quant | Disk | RAM | Quality |
+| --- | --- | --- | --- |
+| F16 | 2.1 GB | ~3 GB | reference |
+| Q8_0 | 1.1 GB | ~2 GB | ~indistinguishable from F16 |
+| **Q4_K_M** | **657 MB** | **~1.3 GB** | small drop, ideal for laptops |
+
+## Common pitfalls
+
+- **Slow on CPU + large context**: drop `-c 131072` to `-c 8192` if you don't need 128 K.
+
+## Building your own GGUF (advanced)
+
+If you've trained your own MiniCPM5-1B variant, build a GGUF with:
+
+```bash
+python convert_hf_to_gguf.py /path/to/your-fp16-hf --outfile out/F16.gguf --outtype f16
+llama-quantize out/F16.gguf out/Q4_K_M.gguf Q4_K_M
+```
+
+## When NOT to use
+
+- NVIDIA GPU + want OpenAI-compatible serving -> `minicpm5-deploy-vllm`
+- Apple Silicon native -> `minicpm5-deploy-mlx` is faster
+- Just want one-line desktop run -> `minicpm5-deploy-ollama`
+- Want a desktop GUI -> `minicpm5-deploy-lmstudio`
