demo-data.js

Emitted only when the build is run with --seed. Creates the sample rows declared under the mapping's demo_items, so a freshly deployed site can be demonstrated with realistic content in seconds — and torn down just as fast.

The marker contract

Every demo row's Title begins with [DEMO] . The marker is the whole contract:

• It is visible in every view and form, so nobody mistakes demo content for records.
• Each row's text identifies it as demonstration data to delete before active use.
• rollback.js trusts it: a list whose items are all marked is demo-only content and is removed without the non-empty refusal prompt — deploy, demonstrate, delete.

The build validator enforces the marker on every declared demo Title, so an unmarked demo row cannot be produced.

Value semantics

Declared values resolve at generation and run time (see demo_items for the grammar):

• "@me" on a person column writes the pasting operator.
• "today+N" / "today-N" on a date column resolves against the day the demo runs, so cadence-driven surfaces (reviews due, overdue, tolerance expiring) light up whenever it is demonstrated.
• demo_ref links resolve to the Ids of rows created earlier in the same run, following list dependency order.

Idempotence

Rows are matched by Title: re-pasting skips existing rows (their Ids still resolve for later demo_ref links) and never duplicates. Paste order is deploy.js first, then demo-data.js, both from the same bundle.
