Lockfile pin-delta engine projection
====================================

This directory is a bounded source projection of

  epistemedeus/samedaydesk
  tools/lockfile-pin-delta/
  git SHA fba9d14872bc4c04214e527b9edfb30c2123c9e7

selected by W5-M01 as the first supplied-input offer and implemented at
that SHA by W5-M03. It is not a copy of the SameDayDesk repository, not a
second payment stack, and not a live settlement engine.

Pin equality uses lockfile name, version, integrity, and resolved. An
injected hasher must not be treated as pin equality. `purchaseAuthority`
and `paidValueClaim` stay false. `settlement` stays
`nonsettling-prototype`. Do not flip a `sold` flag to manufacture a sale.

The public CLI remains `bin/lockfile-delta.mjs` (local files only). The
merchant HTTP adapter must not accept caller filesystem paths, arbitrary
commands, or arbitrary network fetch.

See FEATURE-MAP.md in this directory for the engine contract.
The merchant repository LICENSE (MIT, SameDayDesk) covers this projection.
