7 * ─────────────────────────────────────────────────────────────────────────────
8 *
9 * LockItIn is open-source, autonomous blockchain infrastructure that enables
10 * peer-to-peer commitments on natural-language statements resolved by VERO.
11 *
12 * VERO ("Verification Engine for Resolution Outcomes") is the protocol's
13 * DAO-elected oracle system. The DAO may vote to change the underlying
14 * oracle provider, model, prompt, or any oracle behavior at any time via
15 * timelocked governance proposals (30-day notice once timelock is activated).
16 *
17 * This smart contract:
18 * • Is non-custodial and holds user funds only as required for autonomous settlement
19 * • Does not provide custodial accounts or intermediary services
20 * • Does not set terms, take principal exposure, or determine outcomes
21 * • Executes deterministically based on immutable logic and VERO responses
22 *
23 * Parties who interact with this contract explicitly agree that:
24 * • Outcomes are determined solely by the VERO response (YES / NO / VOID)
25 * • The DAO governs all aspects of VERO and may change it at any time
26 * • Funds may be permanently forfeited due to unfavorable outcomes or protocol fees
27 * • Smart contract, oracle, and blockchain risks are inherent and assumed
28 *
29 * THIS SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND.
30 * USE AT YOUR OWN RISK.

41 * VERSION 1.3.0 CHANGES:
42 * - Added bytes32 tag field for frontend filtering and ecosystem decentralization
43 * - Tag is indexed in CommitmentCreated event for efficient log queries
44 * - Enables independent frontends to build curated feeds without centralized indexers
45 *
46 * ═══════════════════════════════════════════════════════════════════════════════
47 * TAG SYSTEM (bytes32) — Frontend / Indexing Metadata
48 * ═══════════════════════════════════════════════════════════════════════════════
49 *
50 * Overview:
51 * The `tag` field is OPTIONAL metadata for event indexing and UI filtering.
52 * It does NOT affect settlement, fees, oracle behavior, or any protocol logic.
53 * This protocol does NOT interpret, validate, or enforce tags.
54 *
55 * Recommended Derivation:
56 * Canonical string: "<namespace>:<key>"
57 * Encoding: UTF-8 bytes
58 * Hash: bytes32 tag = keccak256(bytes(canonical))
59 *
60 * Namespace Guidelines:
61 * Use an identifier you "control" socially to avoid collisions:
62 * - A domain name: "lockitin.xyz"
63 * - An ENS name: "lockitin.eth"
64 * - A stable org/community identifier
65 * Lowercase recommended to avoid accidental duplicates.
66 *
67 * Key Guidelines:
68 * A lowercase slug is recommended. Charset: [a-z0-9._-]
69 *
70 * Examples:
71 * Canonical String Hash
72 * ───────────────────────── ────────────────────────────────
73 * "lockitin.xyz:featured" → keccak256("lockitin.xyz:featured")
74 * "lockitin.xyz:politics" → keccak256("lockitin.xyz:politics")
75 * "alice.eth:my-feed" → keccak256("alice.eth:my-feed")
76 * "farcaster.xyz:frames" → keccak256("farcaster.xyz:frames")
77 *
78 * Special Values:
79 * bytes32(0) is valid and means "no tag" (untagged commitment).
80 *
81 * Client display:
82 * - On-chain stores only the hash (bytes32). Human-readable labels are a client concern.
83 * - Each frontend may maintain its own registry (bytes32 -> string) for known tags.
84 * - Unknown tags can be displayed as hex.
85 *
86 * Security Note:
87 * Tags are UNTRUSTED user input. Any user can set any tag hash. Treat
88 * tags as hints for indexing/filtering, not as authentication or
89 * endorsement. Use allowlists/curation for "official" feeds.
90 *
91 * ═══════════════════════════════════════════════════════════════════════════════
92 * VERO Oracle System (Multi-Source Architecture)
93 * ═══════════════════════════════════════════════════════════════════════════════
94 *
95 * VERO ("Verification Engine for Resolution Outcomes") is the DAO-elected
96 * oracle that resolves commitments. All VERO parameters are DAO-governed
97 * with an optional 30-day timelock for transparency:
98 * - veroSource: JavaScript execution logic (AI routing + multi-source data fetch + evaluation)
99 * - apiEndpoint: LLM provider API URL
100 * - defaultModel: AI model identifier
101 * - systemPrompt: Instructions sent to the AI for evaluation
102 * - veroTemperature: Model randomness setting
103 * - donId: Chainlink DON identifier
104 *
105 * v1.2 introduces intelligent data source routing:
106 * - Step 1: AI analyzes statement and decides data source
107 * - Step 2: Fetch data from Twelve Data (prices) OR Exa (web) OR Visual Crossing (weather)
108 * - Step 3: AI evaluates statement against fetched data
109 *
110 * Provider-agnostic secrets (SEARCH_API_KEY, LLM_API_KEY, TWELVE_API_KEY, WEATHER_API_KEY):
111 * - SEARCH_API_KEY: Exa API key for web search
112 * - LLM_API_KEY: xAI/Grok API key for AI inference
113 * - TWELVE_API_KEY: Twelve Data API key for market prices
114 * - WEATHER_API_KEY: Visual Crossing API key for weather data
115 *
116 * Current default configuration:
117 * - Search: Exa API (context string, 5 results, live crawl preferred)
118 * - Market Data: Twelve Data API (crypto, stocks, forex, commodities)
119 * - Weather: Visual Crossing API (historical and forecast, location-based)
120 * - Inference: xAI Grok (grok-4-1-fast-non-reasoning, temperature 0)
121 *
122 * Safety Philosophy:
123 * - Default to VOID (refund both) on any ambiguity
124 * - 7-day emergency void escape hatch if oracle fails
125 * - 30-day timeout void if no one calls resolution
126 * - Mutual exit: both parties can back out while Locked
127 * - No pause function - immutability over control
128 *
129 * Fee Structure (all DAO-adjustable within bounds via Governor):
130 * - Creation fee: $0-$10, starts at $0
131 * - Resolution fee: $0.20-$5, starts at $1 (from pot)
132 * - DAO fee: 0.1%-10%, starts at 0.3% (% of pot)
133 * - Tx Builder fee: 0-1%, starts at 0.2% (% of pot)
134 * - $5 USDC minimum commitment per side
135 * - LOCKIT holders get 0-50% discount on protocol fees
