Receipts - print the check

Receipts are per-run cost artifacts written by serve and simmer into the current repo at .sous-chef/receipts/<utc-timestamp>.md (ignored via .git/info/exclude, never committed). Each holds the run's measured numbers and ends with a shareable one-liner. The global ledger (~/.sous-chef/ledger.jsonl) stays the cross-repo running tab; receipts are the per-run, per-repo story.

Printing the check

Read the last 10 receipts by filename (newest last) and render one table:

| when | task | worker | tokens | ~cost | ~saved vs Fable list | verdict |

Close with one line - "last N runs: ~$X of worker spend, ~$Y saved vs same-token Fable list." Sum only lines that exist; a receipt missing a number contributes nothing to that column - say so rather than papering over it.

If the user wants to share one, print that receipt's quoted summary verbatim - it is written to be pasted unedited.

No .sous-chef/receipts/ here? Say so - receipts appear after the first serve or simmer in this repo (a bare fire tabs the ledger, not receipts).

The files behind it

• references/receipt-template.md - the format serve and simmer write, and the honesty rules every number follows.
• references/prices.md - the rough price table (API list, dated); edit it when list prices move.
