Brummel 8ac8756682 iter raw-buf.4 rawbuf-payload-termnew-desugar (DONE, drop-call deferred to .5): RawBuf works, prints 60 (refs #7) 
Ships RawBuf end-to-end as a consumer of the raw-buf.3 scope-qualified
intrinsic mechanism, plus the general Term::New construction sugar.
Working subset committed; the drop-CALL ratification (no-leak) is
re-carved to raw-buf.5 (see b49f57d) — the flat drop FUNCTION ships here,
its call-insertion needs a codegen resolution mechanism.

What ships (all green):
- raw_buf kernel-tier submodule (crates/ailang-kernel/src/raw_buf/):
  RawBuf TypeDef (param-in {Int,Float,Bool}, ctor B a) + four
  (intrinsic) ops new/get/set/size. parse_raw_buf + workspace injection
  (kernel-tier auto-imported); workspace count 4 -> 5.
- 12 scope-qualified INTERCEPTS entries RawBuf_{new,get,set,size}__{Int,
  Float,Bool} + emit fns: new allocs an @ailang_rc_alloc slab
  (8-byte i64 size header + n*width element bytes), get/set
  getelementptr+load/store at offset 8 + i*width, size loads the header.
  Mechanical on the raw-buf.3 naming + bijection machinery; bijection
  green (4 markers -> 12 entries).
- Term::New desugar (crates/ailang-core/src/desugar.rs): (new T <types>
  <values>) -> (app T.new <values>), runs before check so the
  type-scoped callee flows through the raw-buf.3 scope threading to
  RawBuf_new__T; drops the NewArg::Type (element type inferred from
  use). Both codegen Term::New deferral arms removed (replaced with
  unreachable!). Ratified by new_stubt_builds_and_runs.
- Flat intrinsic-storage drop FUNCTION @drop_raw_buf_RawBuf (single
  @ailang_rc_dec on the slab), emitted for any TypeDef whose new op is
  (intrinsic)-bodied — distinguishes RawBuf (intrinsic new) from StubT
  (real-body new -> generic ADT drop).
- E2E: raw_buf_int (-> 60), raw_buf_float (-> 4.0), raw_buf_bool
  (-> 42), raw_buf_param_in_reject (param-not-in-restricted-set).

In-scope additions beyond the literal plan (both sound, ratified):
- qualify_workspace_term now normalises a monomorphic cross-module
  type-scoped callee (StubT.new) to <home>.f; without it
  new_stubt_builds_and_runs cannot build (StubT.new is monomorphic, so
  the raw-buf.3 poly-mono path mints no symbol). Same-module + polymorphic
  callees carved out.
- diagnostic-behaviour: (new T ..) missing-new-op now surfaces
  type-scoped-member-not-found (desugar runs before check, bypassing
  synth's Term::New arm); new-arg-kind-mismatch obsoleted. Two unit
  tests updated to the new behaviour. param-in reject unaffected.

The 5 .ll snapshots gained @drop_raw_buf_RawBuf (+ partial) — injecting
raw_buf emits its drop fn into every program; benign, regenerated to the
final IR. (The plan's "snapshots stay green" assumption was wrong.)

Verification (orchestrator, this session): cargo test --workspace 676
passed / 0 failed / 2 ignored. raw_buf_int_e2e prints 60; bijection,
round-trip, new_stubt, float/bool/reject all green. The raw_buf_no_leak
test is NOT in this commit — it moves to raw-buf.5 with the drop-call
resolution that makes it pass (the slab currently leaks at scope close;
tracked, fixed next iter; milestone not released until close).

Brummel fd37fa6489 iter raw-buf.3 typescoped-intrinsic-mechanism (DONE 2/2): scope-qualified mono symbols + bijection expansion (refs #7) 
New language mechanism: a type-scoped polymorphic top-level (intrinsic)
op now mints a scope-qualified mono symbol (StubT_peek__Int, not the
colliding bare peek__Int), and the intrinsic<->intercept bijection
expresses one such polymorphic marker as its N per-param-in-element
entries. Ratified standalone on the stub via a new StubT.peek op; no
RawBuf, no Term::New, no codegen E2E this iteration (RawBuf consumes the
mechanism in raw-buf.4).

Task 1 — scope threading. Added scope: Option<String> to FreeFnCall +
MonoTarget::FreeFn + the synth free_fn_owner tuple. Populated Some(prefix)
ONLY on the type-scoped T.f resolution branch (lib.rs:3538, gated on
type_home.is_some()); None on every local / same-module / implicit-import
branch, so existing bare-resolved symbols stay byte-identical. Consumed
via a scoped_base helper at both mono-symbol mint sites (synthesise +
rewrite, which read the same MonoTarget → automatically in lockstep) and
folded into mono_target_key so a scoped op and a bare op of the same name
never dedup-collide.

Task 2 — ratifier + bijection. Added StubT.peek to the stub source;
extended workspace_intrinsic_markers with a type-scoped-poly arm that
finds the unique same-module TypeDef referenced in the fn signature and
expands over its param-in set, building the T_f__<elem> strings via the
SAME mono_symbol_n on Type::Con elems so collector and mint agree
byte-for-byte; registered StubT_peek__Int/Float entries + emit fns;
extended kernel_stub_module_round_trips to cover peek; added
mono_scoped_symbol integration test (own-param calls, no Term::New, no
codegen — asserts both scoped symbols minted and bare peek__Int absent).

Latent bug fixed inline (regression caught at the full-suite gate, RED via
the existing escape_local_demo E2E). kernel_stub is implicitly imported,
so poly_free_fn_names_for_module unconditionally added peek's bare name to
every consumer; a consumer with its OWN monomorphic peek then had its
local call mistreated as a poly-free-fn site, over-advancing the mono slot
cursor and misaligning a print target. Fix: suppress the bare
implicit-import name when the current module declares a same-name global,
mirroring synth's resolution ladder (same-module global beats
implicit-import). Applied in lockstep to both poly_free_fn name + and
constraint-count maps; dot-qualified / type-scoped spellings stay
unconditional. This was a pre-existing inconsistency between mono's
name-set and synth's resolution that peek (first implicitly-imported poly
free fn colliding with a fixture-local name) exposed.

Plan deviations (all sound): collect_con_heads omits Borrow/Own recursion
(no such Type variant — borrow/own are ParamMode on Type::Fn, verified
ast.rs:752); scope bound via the existing synthesise_mono_fn_for_free_fn
MonoTarget destructure rather than a new param; the mono-pin fixture uses
own params (borrow + peek-returns-a trips consume-while-borrowed; peek is
never instantiated so the mode is immaterial to the scope-symbol
ratification).

Verification (orchestrator, this session): cargo build --workspace clean;
cargo test --workspace 670 passed / 0 failed / 2 ignored (669 baseline +
the one new mono test). Bijection green (1 marker -> 2 entries),
round-trip green, escape_local_demo green. .ll snapshots unchanged (peek
polymorphic -> never instantiated without a call site). Existing eq__*/
compare__*/float_* symbols byte-identical (mono_hash_stability green).

Brummel fbdbe740e6 iter raw-buf.2-kernel-rename (DONE 2/2): ailang-kernel-stub → ailang-kernel family-crate (refs #7) 
Pure crate rename, zero behavioural change. ailang-kernel-stub becomes
the ailang-kernel family-crate: a re-export hub (src/lib.rs) plus one
submodule per kernel-tier module (today only kernel_stub:
src/kernel_stub/{mod.rs, source.ail}). raw-buf.3 plugs raw_buf in as a
sibling submodule; this iter only builds the home.

Task 1 (atomic — the rename breaks the build until every site is
threaded):
- git mv crates/ailang-kernel-stub → crates/ailang-kernel.
- Carved the STUB_AIL Form-A body verbatim (byte-identical, verified
  via diff against HEAD's raw string) into src/kernel_stub/source.ail,
  loaded by mod.rs via include_str!. The answer (intrinsic) fn is
  byte-preserved — its INTERCEPTS bijection partner stays pinned.
- lib.rs is now the hub: `pub use kernel_stub::SOURCE as STUB_AIL;`.
  The public symbol STUB_AIL is preserved, so ailang-surface and the
  bijection test bind to it unchanged.
- 8 compile sites threaded across 6 files: Cargo package name,
  workspace member + dep-alias, ailang-surface dep, loader.rs
  use-paths (ailang_kernel_stub → ailang_kernel). Cargo.lock
  auto-regenerated.

Task 2 (doc/ledger honesty, no build impact):
- design/INDEX.md, CLAUDE.md code-layout row + lockstep-pair row,
  design/models/0007 ×2 — crate-path strings updated to the new
  ailang-kernel/src/kernel_stub path.
- Scope note: the spec's raw-buf.2 Components row named only
  design/INDEX.md + the CLAUDE.md code-layout row. plan-recon found two
  more present-tense crate-path refs (CLAUDE.md:312 lockstep row,
  model 0007:8/235). Folded them in per the honesty-rule — a rename
  that leaves stale present-state paths is an incomplete rename.
  Path-only; the retirement narrative stays for raw-buf.4.

The AILang module name kernel_stub (the Form-A string + parse_kernel_stub
fn) is deliberately unchanged — only the crate identifier moved.

Verification (orchestrator, this session): cargo build --workspace
clean; cargo test --workspace 669 passed / 0 failed / 2 ignored
(baseline held exactly — no test added/removed). Carve byte-identity
confirmed by diff; no stale ailang-kernel-stub / ailang_kernel_stub
refs remain in-tree (git grep, excl. history + lockfile). The four
rename-invisible ratifiers (kernel_stub_module_round_trips,
intercepts_bijection_with_intrinsic_markers, .ll snapshots,
workspace_pin) all green via the preserved re-export.
