Tax advisor transcript

This transcript is self-contained: reproduce it end to end with any fresh test token from /dashboard/tokens. No preset, no address book entry, and no prior configuration are assumed; every precondition is created inline or as an earlier step in this same transcript.

Setup: tax firm "Müller" mints a fresh test token in the Test-Token tab at /dashboard/tokens and pastes it as the Authorization header. Every call below runs with isTest:true, is fully reproducible, and costs nothing.

This transcript demonstrates the preset the tax firm uses daily. It is created here as an explicit first step so the transcript has no hidden precondition (Finding 12): preset_save, then order_send referencing it by name.

The recipient below comes straight from the address_search_company result, inline in the order_send call, so this transcript has no address-book precondition either.
Briefdesign: the firm saves its reusable letterhead once with letter_design_save. The Infoblock carries "Unser Zeichen" as a fixed value and "Vorgang" filled per letter from reference; the QR payload template resolves {{vorgangsnummer}} the same way. An invalid design (e.g. a box reaching into the address window) would be rejected here immediately with DESIGN_ZONE_VIOLATION, before it is ever used on a send.

Before using the design on a real send, the firm previews it with the sample vorgangsnummer that this case will use. Nothing is charged and nothing is sent; open previewUrl to see the letterhead, info block and QR exactly as a real letter would carry them.

designId and reference ride along on order_send: the info block and QR resolve vorgangsnummer:"2026-0042" for this one letter, and the order records designId + a design_hash for audit even though this call is not shown in the result data below (that surfaces on a dryRun preview instead).
Rehearsal scope (§1.1 of the sandbox design, rubric item 3): the kanzlei-einspruch preset actually requests review mode. For a test token the sandbox forces effectiveMode:auto instead: your LIVE send with this preset would land in the approval queue, but the sandbox only rehearses the auto-send tail. This is a deliberate, narrow simplification, not a silent divergence.

costCents:759 is the real market price a live send would cost, shown for full cost transparency (no hidden costs) even in a rehearsal. Nothing is actually charged: the sandbox books a 0-cent, is_test:true wallet row (balance_after equals balance_before). The PDF is watermarked "TESTVERSAND / SANDBOX" and stored under the test/ prefix.

Polling the same call again after the simulated timing in generated/sandbox.json (20s to "accepted", 60s to "delivered") advances the status. Nothing is written; it is computed fresh from created_at on every read.

That is the full, self-contained sandbox run: 10 tool calls, 0 cents charged, no real letter sent. Reproduce it end to end with any fresh test token.
