Explain what moved any GL account, and why

**Objective:** Explain the movement in GL account `{account}` between `{from-date}` (default the first day of this month) and `{to-date}` (default today): how much it moved, which entries drove it, and which modules they came from.

Pass `{company}` as `company` on every call (if it is empty, omit `company` and the default company is used). Pass a generous `max-records` (1000). If a result comes back with exactly that many rows, say the result may be truncated.

**Step 1: Identify the account**

Call `dynamics-gp-get-gl-account` with `account-number` set to `{account}`. If that returns nothing, call it again with `account-description.contains` set to `{account}`. If more than one account matches, list number, description and account type and stop. Note the `posting-type` (balance sheet or profit and loss), `typical-balance` and `active`.

**Step 2: Period balances**

Call `dynamics-gp-get-gl-account-summary` filtered by `account-number` and the `year` (or years) the range falls in. List `debit-amount`, `credit-amount` and `period-balance` for each `period-id` in range.

**Step 3: Transactions**

Call `dynamics-gp-get-gl-account-transaction` filtered by `account-number`, `transaction-date.from` and `transaction-date.to`.

* Net movement = total debits minus total credits (reverse the sign if `typical-balance` is credit, and say you did).
* Group by `series` and `source-document` with totals.
* The ten largest entries by absolute amount: date, journal entry, description, reference, originating document number, originating master name.
* Flag entries that look unusual: round amounts, entries on a weekend, a journal entry that both debits and credits this account, or a series that does not normally post here.

**Step 4: Reconcile**

Compare the net movement from Step 3 with the period balances from Step 2. If they differ, say by how much and give the likely reasons (entries outside the date range but inside the period, unposted or historical-year entries). Do not force them to agree.

**Step 5: Report**

Account header line, the period table, movement by series, the top-ten table, flagged entries, and the reconciliation note.

**Rules & Guidelines:**

* Read-only. Do not call `dynamics-gp-gl-account-transaction-add`, `dynamics-gp-gl-account-update`, `dynamics-gp-gl-account-note` or any tool whose name does not contain `get`.
* An unusual entry is a question to ask, not an error. Word it that way.

**Validation:**

* If the account is inactive, say so before anything else.
* If there are no transactions in the range, report the period balances only.
