Trust boundary checks - #7

Conversation
Add `assert_axioms`, a concise sibling of `assert_no_sorry` that pins a declaration's trusted base to a tier — standard axioms, or standard plus `native_decide` — by matching on the axiom kind rather than its toolchain-dependent name. Use it in a new `CompElliptic.TrustBoundary` census, imported by the library root so `lake build` enforces it. Correct the README: drop the stale `Lean.ofReduceBool` claim (current toolchains add a per-declaration `native_decide` axiom instead), and hedge that independent re-checking catches a bad oracle only if someone performs the check.

The phrase was required under the 1910 Buenos Aires convention but has no effect under Berne; every Buenos Aires signatory has been a Berne signatory since 2000. Remove it from all file headers, including the copyright line the field-file generators emit (so regeneration still reproduces the committed files).

Supports CompElliptic's independently re-checkable trust principle with a build-time check, and corrects the trust-discipline wording in its prose description.

The second commit removes
"All rights reserved."from every file header (it was required under the 1910 Buenos Aires convention but has no effect under Berne, and every Buenos Aires signatory has been a Berne signatory since 2000). This includes the copyright line the field-file generators emit, so thatscripts/gen_*.pystill reproduces the committed field files.🤖 Claude Opus 4.8
