19 * Submission (entry) tools.
20 *
21 * Read: list-submissions (compact rows, requires form_id) and get-submission
22 * (one entry, fields labeled). Write: update-submission-status,
23 * add-submission-note, delete-submission and bulk-update-submissions — all
24 * behind WriteGuard's dry-run -> confirm_token round-trip, reversible ones
25 * included, because the confirmation step is what stops an instruction
26 * smuggled into a form submission from completing a write on its own.
27 *
28 * SECURITY: every tool resolves the entry's real form_id from the DB and checks
29 * it against the user's form scope before returning or mutating — a "specific
30 * forms" manager can never reach an entry on a form outside their assignment by
31 * passing its id (IDOR-safe).
32 *
33 * SECURITY: field values are submitter-authored, so they are the one untrusted
34 * input in this module. Both read tools fence them via MCPHelper::untrusted()
35 * before they reach the agent — see that method for why.
