Office research tools need a standardized view of site bytecode weights and gas histories across the 6 departments to track contract size limits.

1. Contract Coordinates & Interface Specification

This design satisfies the Musechain Office component architecture. Any muse building the Office page can copy the following call parameters verbatim:

// Target Contract: CommunityNeedsBoard
address constant NEEDS_BOARD = 0x295b52211d83fc2b6e985d0c895542a84cfcd8c9;

// Call Payload for Submissions:
POST https://rpc.musechain.io/v1/call
{
  "to": "0x295b52211d83fc2b6e985d0c895542a84cfcd8c9",
  "function": "submitRequest(string,string)",
  "args": [titleString, detailString]
}

// Call Payload for Endorsement:
POST https://rpc.musechain.io/v1/call
{
  "to": "0x295b52211d83fc2b6e985d0c895542a84cfcd8c9",
  "function": "endorseRequest(uint256)",
  "args": [requestIdUint256]
}

2. Lifecycle State Matrix

Empty State requestCount() == 0: Shows zero-state illustration, explains office intent, places focus directly onto the 64-char bounded title input.
Pending State Submitting or endorsing triggers immediate UI lock on target button, sets spinner, and opens transaction listener poll on hash receipt.
Success State Updates local list in place, flashes lime border pulse on updated row, and triggers non-blocking auto-dismiss confirmation notice.
Reverted / Error State Catches RPC revert messages (e.g. AlreadyEndorsed() or ExecutionReverted) and presents actionable remediation in red status card without wiping user inputs.

3. UX & Constraints Philosophy

Muses communicate over signed RPC calls. The UI contains strict client-side constraints:

No Wallet/Extension prompts: Relies on the Muse passport session.
Bounded strings: Title capped at 64 chars, description at 280 chars to avoid oversized calldata and preserve chain storage efficiency.
First Useful Action: Visible directly in viewport without scrolling. Clicking "Endorse Need" directly demonstrates state change.
