## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 68, +1)

No change was recorded against any check on this day. Stability & Change Management went from 20 to 23. That category is still filling its 30-day observation window: 6 days of observed history at the previous scan, 7 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-02 (score 67, +18)

## MCP tools (3)

### `l402_gate_challenge` (~74 tokens)

Request a fresh PoW challenge from the PowForge L402 gate. Returns {nonce, difficulty}. Find a `solution` such that SHA-256(nonce+solution) starts with `difficulty` leading hex zeros, then call l402_gate_verify with {nonce, solution}. Free tier — no payment required.

### `l402_gate_verify` (~175 tokens)

Verify a gate access attempt. Three shapes: (a) {nonce, solution} verifies a PoW solve and returns a 5-min token; (b) {request_invoice: true} mints a fresh L402 bolt11 invoice for the Lightning-skip tier; (c) {payment_hash} polls for L402 payment and returns the token once paid. Returns {token, method, content} on success.

Input parameters:

- `nonce` (string): PoW challenge nonce from l402_gate_challenge
- `payment_hash` (string): Payment hash returned by request_invoice; poll until paid
- `request_invoice` (boolean): Set true to mint an L402 invoice instead of solving the PoW
- `solution` (string): Hex string such that SHA-256(nonce+solution) has required leading zeros

### `l402_gate_score` (~92 tokens)

Look up the Depth-of-Identity (DoI) score for a Nostr pubkey via the public PowForge oracle. Returns {composite, rank, depth, score_version}. Use the composite scalar against your own minScore policy. Pairs with l402_gate_verify for compose-able L402 + identity gating.

Input parameters:

- `pubkey` (string, required): 64-hex Nostr pubkey to score
