Invariant 17 makes the intent-to-spec relation 1:n; the intent chapter's kinds table maps a standalone intent to one spec (1:1)

Invariant 17 makes the intent-to-spec relation 1:n; the intent chapter's kinds table maps a standalone intent to one spec (1:1)

A premise contradiction (severity minor) found by the cross-document consistency pass.

• End A: .abcd/development/brief/02-constraints/03-invariants.md:171 — "the intent↔spec relation is 1:n: an intent that has been thought through stands as written"
• End B: .abcd/development/brief/04-surfaces/05-intent.md:83 — "One spec (1:1) | itd-3, itd-4, itd-7, most of the corpus"

03-invariants holds that an intent owns one or more specs and ships when its last one closes, while the kinds table in 05-intent states a standalone intent maps to one spec, 1:1. A standalone intent with a remainder spec is legal under the invariant and excluded by the table.
