## 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.

### 2026-08-15 (score 74, +1)

No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

### 2026-08-14 (score 73, +3)

- [functional improvement] Stability: unverified → 0.23

### 2026-08-11 (score 70, +2)

- [functional] We updated how we score, so this day's move reflects our rubric, not a change to the server

### 2026-08-07 (score 68)

First indexed and scored.

## MCP tools (4)

### `xql_validate` (~39 tokens)

Validate XQL query text by parsing and planning it, without executing it against live data.

Input parameters:

- `query` (string, required): Raw XQL query text

### `xql_explain` (~40 tokens)

Parse and plan an XQL query, returning its execution plan and a human-readable explanation.

Input parameters:

- `query` (string, required): Raw XQL query text

### `xql_run` (~63 tokens)

Parse, plan, and execute an XQL query against live market data, returning matching instruments. Call xql_validate on the query first to catch syntax errors before spending a live-data round trip on this call.

Input parameters:

- `query` (string, required): Raw XQL query text

### `xql_nl_reference` (~93 tokens)

Fetch the XQL natural-language reference document, mapping retail-trader phrasing to valid XQL syntax and documenting hard limits (300-bar lookback ceiling, closed market/timeframe enums, the atr no-source-argument exception, etc.). Call this before writing a query, or after xql_validate/xql_explain/xql_run returns isError: true, to see the exact construct you likely got wrong.
