PLANT ORGANISM — one contract on robinhood chain, the body of a digital plant that lives somewhere real: its location's weather decides how it grows, holders decide where to place it. no token here (the PLANT token + pool + hook come in a second launch that pays into this contract). no admin, no upgrade, no pause; all numbers constant. constructor (static args): IMD = 0x5f7bb59365ce557c26dbcaa4ee9d39a4b95b7127, signer = 0x5598aa9146215bc13eb26f2c692ad1461fd32982, FALLBACK_CELL = 10223579, deployer = $owner. cell packing: uint32 = uint16(int16 lat in quarter degrees) << 16 | uint16(int16 lon); lisbon (155, −37) = 0x009BFFDB = 10223579. day index = unix day (timestamp / 86400); lastSettledDay starts at the deployment day. BIND (the only privileged call, once): bind(hook, questionHash) by deployer, only while unbound: reads hook.organism() == this and hook.plant(); stores plant, hook and QUESTION_HASH (the keccak of the frozen oracle question; set once, never changed); emits Bound. after that the deployer has no powers. until bound, park/redeem revert and settle only advances lastSettledDay. MONEY: IMD arrives from the launch factory's fee distributor (1% of trades) and from the hook (0.75%); any IMD transferred in counts. pot = IMD held − backing − gardener IMD owed. backing is redeemable IMD. STATE: location (cell = int16 lat + int16 lon, quarter degrees; 0 = nowhere), water 0..100 (starts 50), backing, parked[cell][holder], parkedTotal[cell], burned (PLANT held forever), lastSettledDay. HOURS (24 per utc day, inside settle): rain → water = min(100, water+3). sun with water ≥ 1 → SIP: water −1; sip = pot/10; backing += 2/3 sip; gardener pool += 1/3 sip. else nothing. SETTLE(attestation, sig), anyone may call: imd OracleAttestation v2 (EIP-712 domain name "IdentityMD Oracle", version "2", chainId 4663, verifyingContract = THIS contract; struct fields as published by imd: requestId, chainId, questionHash, answerType, answer, figure, fromBlock, toBlock, blockHash, panelJobId, panelSize, quorum, agreed, issuedAt, expiresAt), signed by the oracle signer. require attestation.chainId == 4663, attestation.questionHash == QUESTION_HASH, answerType == bytes32[] with exactly 3 words (so no other oracle request can feed this contract). word0: bits 0..23 sun mask, 24..47 rain mask, 48 challenger valid, 64..95 challenger cell, 96..127 day index; word1/2 hourly temp + wind, only emitted. require valid sig, issuedAt ≤ now ≤ expiresAt, day == lastSettledDay+1 (missed days in order); apply hours; READ; pay caller 1% of pot; emit Settled(day, words, sips, backing, water, location). READ: C = current, L = challenger. if L ≠ C and valid and parkedTotal[L] > parkedTotal[C] and parkedTotal[L] ≥ 5% of PLANT supply → location = L (Moved); else stay. no minimum stay. the gardener pool goes pro rata to holders parked behind C as of the previous settle (reward-per-token accumulator per cell + holder checkpoints; tokens parked mid-day activate at the next settle; unparked tokens drop out); if nobody is parked behind C it goes to backing. claim() any time, in IMD. PARK/UNPARK(cell, amount): any time, any cell, incl. the current one. parking proposes; no list on chain. REDEEM(amount): floor = backing / (PLANT supply − burned); pays amount × floor × 90% in IMD from backing; 10% stays; PLANT is pulled in and held forever. unpark first. floor never decreases. BIRTH: location 0, no hours while 0; the first settle with a valid challenger ≥ 5% moves it; after 3 empty settles → FALLBACK_CELL (lisbon, (155, −37)). DEAD PLANT: no successful settle for 30 days → pot merges into backing and redeem pays full floor. SIGNER ROTATION (no governance, no votes): rotateSigner(newSigner, sig) is accepted only if sig is an EIP-712 message from the CURRENT signer naming this contract and the new address; the previous signer stays valid for 30 more days. holders cannot change the signer. nothing else is settable by anyone. SAFETY: reentrancy guards; no external calls beyond IMD/PLANT transfers; no delegatecall/selfdestruct/proxy/ownable/pausable/roles; uint256 math rounding toward backing; settle O(24), never O(holders); public reads of all state + floor + pot; events for every action. TESTS (foundry): fee inflow → pot; synthetic day from masks; missed-day ordering; fixture attestation accepted, expired/wrong-domain/wrong-signer/v1 rejected; park → settle → claim incl. pending→active; invariants: floor never decreases, pot + backing + owed == IMD held (minus bounties), burned never leaves; move, birth, fallback, dead plant, signer rotation (accepted only from the current signer), bind-once; settle ≤ 400k gas. one-page README: rules in plain words, how to call settle, addresses.
