1. What Is Queued & Why It Matters for TREE Holders & Venues

In Ethereum Mainnet transaction 0x36f7071cb0cae1f60d9b9be05fa381993e04550ee807621134dd08f74fe9dee5 (block 26396588), Treehouse's 5-of-7 Governance Safe (0x22261B4D6F629D8cF946C3524df86bF7222901F6) scheduled operation 0x2f11dcc36860f09b9ef94585589ced1798cef603d133efecd017ce7e544c451f on TimelockController (0x2225DAbFfC7F862c99477381E971E8B1FDaB467e, 432,000s / 5d delay) targeting the UUPS proxy TreehouseToken (TREE) (0x77146784315Ba81904d654466968e3a7c196d1f3):

Decoded UUPS Upgrade & Nested Init Call: Calls upgradeToAndCall(0x0fedcbfEBc293Ad8048726B0F887e6C1126EffA6, 0xad38bf2200000000000000000000000022261b4d6f629d8cf946c3524df86bf7222901f6), upgrading TREE from implementation 0xFC0732c97f3dF6284A7a9De2a8363CE39b497423 to 0x0fedcbfEBc293Ad8048726B0F887e6C1126EffA6 and atomically invoking updateBlacklister(0x22261B4D6F629D8cF946C3524df86bF7222901F6).
New Post-Upgrade 0-Second Freeze Authority: The new implementation inherits Blacklistable and overrides _update(from, to, value) with notBlacklisted(from) notBlacklisted(to) notBlacklisted(msg.sender). While rotating blacklister or upgrading TREE remains gated by onlyOwner (the 5-day TimelockController), the designated 5-of-7 Safe (0x22261B4D6F629D8cF946C3524df86bF7222901F6, threshold/owner state read by scanner at block 26406429, hash 0xb65c04eeddc59de1affade1a5e76250fed78467ad3a69f5d292c5e5f089dab84) gains direct, 0-second blacklist(address) / unBlacklist(address) authority over TREE senders, recipients, and msg.sender callers (including transferFrom spenders).
Asset Scope Distinction: This operation modifies only the TREE governance token (0x77146784315Ba81904d654466968e3a7c196d1f3); it does not alter the tETH LST contract (0xD11c452fc99cF405034ee446803b6F6c1F6d5ED8).

2. Deterministic Verification & ERC-7201 Storage Audit

Verification Check	Attributed On-Chain / Cryptographic Evidence	Status
OZ `hashOperation` Preimage	Independent verifier (block `26406275`): `keccak256(abi.encode(0x7714..d1f3, 0, 0x4f1ef286.., 0x00..00, 0x00..00))` == `0x2f11dcc3...c451f`	Pass
ERC-7201 Namespace Derivation	Independent verifier (block `26406275`): `keccak256(abi.encode(uint256(keccak256("treehouse.storage.Blacklistable")) - 1)) & ~bytes32(uint256(0xff))` == `0xdf68130666baa706ccbe7ae2392f8ae200401e1ace517b31c8be7bd447dd6b00`	Pass
Source-Level Linear Layout Diff	Independent verifier (block `26406275`): shared OZ base contracts in verified source are byte-identical; `Blacklistable` uses only ERC-7201 namespaced storage with zero new linear state variables (`ccipAdmin` linear declaration unchanged); constructors call `_disableInitializers()`	Preserved
Archive Simulation & Access Guard	Scanner archive simulation (block `26406106` / `26406207`): `upgradeToAndCall` simulated from `0x2225...467e` returns `0x`; unprivileged caller reverts `OwnableUnauthorizedAccount` (`0x118cdaa7`)	Pass

3. Curator & Venue Monitoring Summary

Lending & DEX Pool Risk (Before 2026-11-17 04:51 UTC): Any venue accepting TREE as collateral or LP inventory should treat TREE post-execution as an issuer-freezable token (comparable to USDC / USDT blacklist semantics): blacklisting a vault, pool, or borrower address blocks liquidations and transferFrom settlements involving that address.
Scope Note: Storage verification above covers verified Solidity source-level linear declarations and ERC-7201 formula derivation at the pinned block, without certifying compiler artifact equivalence or off-chain signer policy.
