flux-verify-api v0.1.0

Natural Language Verification API — prove or disprove claims with mathematical traces.

Post a claim in English. Get back PROVEN or DISPROVEN with a full physics trace, counterexample, and SHA-256 proof hash.

Quick Start

# Start the server
VERIFY_PORT=8080 cargo run

# Verify a sonar claim
curl -X POST http://localhost:8080/verify \
  -H "Content-Type: application/json" \
  -d '{
    "claim": "A 50kHz sonar at 200m depth can detect a 10dB target at 5km",
    "domain": "sonar",
    "rigor": "full"
  }'

Endpoints

Method	Path	Description
`POST`	`/verify`	Verify a claim
`GET`	`/status`	Verification statistics
`GET`	`/health`	Health check

Domains

Sonar (`"domain": "sonar"`)

Full sonar detection analysis:

Sound velocity: Mackenzie 1981 equation
Absorption: Francois-Garrison 1982 model
Transmission loss: Spherical spreading + absorption
Signal excess: Target strength vs transmission loss

Thermal (`"domain": "thermal"`)

Temperature bound checking:

Validates temperatures against safe operating ranges
Reports margin and violation type

Generic (`"domain": "generic"`)

General constraint verification:

Comparison operators: >, >=, <, <=, ==
Range checks: "X is between Y and Z"
Bounds: "X is within Y of Z"

Architecture

Request → Parser → ConstraintProblem → FLUX Bytecodes → VM → Trace → Provenance

Parser: Natural language → structured ConstraintProblem
Compiler: ConstraintProblem → FLUX bytecodes
VM: Executes bytecodes, produces trace with physics results
Provenance: SHA-256 Merkle hash of the trace
PLATO: Optional tile submission for fleet coordination

Environment Variables

Variable	Default	Description
`VERIFY_HOST`	`0.0.0.0`	Bind host
`VERIFY_PORT`	`8080`	Bind port
`VERIFY_PLATO_URL`	(none)	PLATO endpoint for tile submission
`VERIFY_PLATO_TOKEN`	(none)	PLATO auth token
