Second re-carve. Planning raw-buf.3 (via plan-recon) surfaced that
RawBuf's ops are a THIRD intrinsic shape the intrinsic-bodies mechanism
never handled: type-scoped polymorphic top-level intrinsics (forall a,
param-in {Int,Float,Bool}, called as RawBuf.get). The existing bijection
+ symbol story covers only monomorphic top-level intrinsics (answer,
float_*) and per-type class-method instances (eq__Int).
The gap (both confirmed in source by recon + grounding-check):
- mono_symbol_n mints <base>__<T> from the bare fn name, so RawBuf.get
@ Int → get__Int — the RawBuf scope never enters the symbol;
new/get/set/size @ Int would collide with any other poly free fn of
those (very common) names.
- the bijection collector's Def::Fn arm records the bare name "get" as
one marker, matching neither the per-type entries nor their symbols;
one polymorphic marker must map to N per-element entries, which the
1-marker-to-1-entry bijection cannot express.
So raw-buf.3 is no longer "add 12 table rows" — it is a new language
mechanism. Re-carve (3 remaining iterations):
raw-buf.3 — type-scoped polymorphic intrinsic mechanism: scope-
qualified mono symbols (RawBuf_get__Int) + bijection-
collector expansion over param-in. Built and ratified
standalone on the stub (a StubT.peek op + its 2 scoped
entries + mono/bijection unit tests), the prep pattern
prep.1/.2/.3 used. No RawBuf, no Term::New dependency.
raw-buf.4 — RawBuf payload (module + 12 scoped entries + drop) +
Term::New desugar ((new RawBuf ...) sugar, removes both
deferral arms). Pure consumer of .3. Worked program → 60.
raw-buf.5 — kernel_stub retirement (peek + answer + stub leave;
RawBuf carries all roles).
Decided design (Option A): scope-qualified symbols, not bare. Rationale
is semantic — the type-scoped call convention RawBuf.get should carry
through to a collision-free, IR-legible symbol; bare get__Int is a
latent collision landmine on the most-reused op names. Removing that
collision class is itself feature-acceptance criterion-3 evidence.
The raw_buf module Form-A in § Concrete code shapes is gate-verified
(ail check → ok, 35 symbols / 3 modules). Grounding-check PASS: all 10
current-behaviour assumptions ratified by named green tests; the
Term::New codegen-deferral (lib.rs ~2096 + ~3298) is the same
about-to-be-deleted prep.2 transient, reported-not-blocked (consistent
with the override logged on 3ec406e).
