telos-os 1.3.1

Declarative MILP runtimes: .telos manifests, safe linear/memory expression parsers, PuLP (CBC/HiGHS), actuators

Telos Framework / Telos OS

Telos OS is a Python framework for declarative optimization runtimes: .telos YAML manifests, MILP solving with PuLP (CBC or HiGHS), a temporal TelosRuntime (memory, chained matrices), and optional actuators. Infrastructure-as-Physics is a tagline for describing goals and constraints as math—not a second product line.

New here? docs/START_HERE.md — glossary, telos validate / telos run / telos test, how to read a manifest.

Canonical path: .telos + MILP + runtime

1. Author or generate a .telos file (YAML → TelosSchema).
2. telos validate / telos run / telos test — or embed TelosParser + TelosRuntime in Python.
3. Optionally attach actuators so numeric solutions drive Docker, Kubernetes, or custom side effects.

Expression handling: objectives and invariants use telos.linear_milp—every accepted expression is linear in decision variables; / only when the denominator is decision-free. Memory update strings use telos.memory_expr. Checked-in manifests are covered by corpus tests; dev CI runs Hypothesis fuzz on the parsers (bounded time per sample). Still treat .telos, canvas JSON, and LLM output as trusted configuration. See docs/SDK.md and ../SECURITY.md.

Architecture (MILP-first)

Layer	Module	Role
Manifests	telos/parser.py	TelosParser.load / loads — YAML → validated dict
MILP schema	telos/models.py	TelosSchema, Variable, Memory, etc.
MILP compiler	telos/compiler.py	PuLP TelosCompiler.compile (CBC / HiGHS; see MILP solver below)
Linear expressions	telos/linear_milp.py	Safe parser for objectives / invariants
Memory expressions	telos/memory_expr.py	Safe scalar update evaluator (max/min)
Runtime	telos/runtime.py	TelosRuntime.tick — memory, router→hardware order, actuators
Actuators	telos/actuators/	DockerActuator, KubernetesActuator, FinTechActuator
Debugger	telos/debugger.py	LatentDebugger — Monte Carlo parameters
Generator (optional)	telos/generator.py	LLM → draft .telos
CLI	telos/cli.py	telos run, validate, test, generate; install is stub

Experimental — continuous mode (TIR)

Module	Role
telos/schema.py	TIRSchema — string variable lists, SymPy-oriented (fractional variables)
telos/tir_compiler.py	SciPy SLSQP for TIRSchema
telos/agent.py	Natural language → TIR (not the primary .telos workflow)
main.py	Demos: intent → TIR → SciPy, or hand-authored finance TIR

TIR does not provide mixed-integer guarantees. Prefer .telos + PuLP for production-style discrete decisions.

Requirements

Python 3.10+ (3.13 works in development).

Install

Editable (registers telos CLI):

cd telos-framework
python -m pip install -e ".[all]"   # + docker, k8s, server
# or minimal MILP SDK:
python -m pip install -e .

PyPI: pip install telos-os — extras [docker], [kubernetes], [server], [milp-highs] (HiGHS / highspy for native ARM64 solves), [all].

Legacy: python -m pip install -r requirements.txt

License: MIT (LICENSE).

---

First commands (MILP)

telos validate examples/router_minimal.telos
telos run examples/router_minimal.telos --actuator none --params examples/params/router_minimal.json
telos test vulnerable.telos --iters 500

MILP backend: telos validate and telos run accept --solver {auto,cbc,highs} (sets TELOS_PULP_SOLVER for that process). On Apple Silicon (arm64), the default auto uses HiGHS when highspy is installed (recommended: pip install "telos-os[milp-highs]"); otherwise install that extra or pass --solver cbc only if your Python runs under Rosetta (x86_64).

Variable	Purpose
TELOS_PULP_SOLVER	auto (default), cbc, or highs — selects the PuLP MILP backend (see docs/SDK.md).

Optional LLM draft (review output before running):

telos generate "Describe routing, costs, caps..." --out app.telos

Experimental stub (not a registry):

telos install vendor/my-actuator

Backends for generate / agent: OPENAI_API_KEY, or TELOS_LLM_BACKEND=ollama with ollama serve. See Environment variables below.

---

Optional canvas

python server.py

Open http://127.0.0.1:8000 (not file://). Port: TELOS_PORT. TELOS_RELOAD=1 for uvicorn reload (WebSockets can be flaky on Windows).

---

Headless MILP demo

python headless.py

Loads infrastructure.telos and a parameter timeline; uses DockerActuator when Docker is available.

---

Experimental TIR demos (main.py)

python main.py          # intent → agent → TIR → SciPy (optional LLM)
python main.py finance  # hand-authored TIR, no LLM

These illustrate the continuous track only.

---

SDK usage (MILP)

from pathlib import Path
from telos import TelosRuntime, TelosParser, DockerActuator

rt = TelosRuntime()
rt.attach_actuator(DockerActuator())

result = rt.tick(
    {"router": router_dict, "hardware": hardware_dict},
    {"cap_s1": 1.0, "cost_s1": 20.0},
)

schema = TelosParser.load(Path("infrastructure.telos"))
result = rt.tick({"main": schema}, {"us_cap": 1.0, "eu_cost": 20.0})

See docs/SDK.md for the full tick contract.

---

Configuring the agent (TIR / experimental)

TelosAgent backend order when auto: OpenAI if OPENAI_API_KEY, else Ollama if reachable, else mock.

Variable	Purpose
OPENAI_API_KEY	OpenAI
TELOS_LLM_BACKEND	auto · openai · ollama · mock
OLLAMA_HOST	Ollama base URL
TELOS_OLLAMA_MODEL	Model name
TELOS_GENERATOR_MODEL	Chat model for TelosGenerator (default gpt-4o)
TELOS_PORT	Canvas port
TELOS_RELOAD	1 for uvicorn autoreload

---

TIR JSON shape (reference only — experimental)

Expressions must be valid for SymPy (sympify). eq → == 0, ineq → ≥ 0.

{
  "ontology": {
    "variables": ["x", "y"],
    "bounds": [[0.0, 1.0], [0.0, 1.0]]
  },
  "teleology": {
    "direction": "minimize",
    "objective": "x + 2*y"
  },
  "invariants": [
    { "type": "eq", "expression": "x + y - 1.0" },
    { "type": "ineq", "expression": "0.5 - x" }
  ]
}

---

Limitations

• MILP: PuLP with CBC (default on most platforms) or HiGHS (via highspy, used automatically on Darwin arm64 when available); linear expression parser for manifest strings.
• TIR: continuous SLSQP only; experimental / demo-oriented.
• Executable “matrix” is a dict of numbers, not a binary tensor format.
