Milestone-close fieldtest for the raw-buf milestone, milestone-scope
variant: four end-to-end scenarios derived top-down from the milestone
promise (construct via (new RawBuf <elem> <size>), fill/read via
set/get, size-only buffers, element variety across {Int,Float,Bool},
forbidden-element reject at check, buffer threading under own/borrow).
Result confirms the milestone-promise hypothesis — RawBuf is clean
end to end, zero bugs:
- mrb_1 Int fill/read loop: check ok, run + native build both print 70
- mrb_2 Float own->own threading + borrow read: prints 3.5
- mrb_3 size-only Bool buffer (#51 legitimate-but-unobserved case): prints 8
- mrb_4 Unit element: rejected at check with a precise
param-not-in-restricted-set diagnostic; build stops at the same
error, codegen never reached (the #51 fix)
Two [working] findings (carry-on) and one [spec_gap]: the
kernel-extensions whitepaper (design/models/0007) teaches bare-mode
fn-type slots that the post-#55 parser rejects. Verified and triaged
separately; the ledger fix follows in its own commit.
