Decomposes raw-buf.2 (parent spec docs/specs/0054-raw-buf.md
§ Architecture point 2, § Components row 2, § Testing strategy
"raw-buf.2") into 7 atomic tasks:
Task 1 — crate rename + reshape: crates/ailang-kernel-stub/ →
crates/ailang-kernel/, restructured as a family-crate with
src/kernel_stub/{mod.rs,source.ail}; 13 steps covering 8
compile-checked rename sites plus design/INDEX.md + CLAUDE.md
path updates.
Task 2 — add raw_buf submodule: src/raw_buf/{mod.rs,source.ail}
with the spec's Form-A source (4 fns + 1 TypeDef with
param-in (a Int Float Bool)); RAW_BUF_AIL re-export.
Task 3 — wire raw_buf into ailang-surface: parse_raw_buf fn,
re-export at lib.rs:39, workspace injection alongside the
existing kernel_stub block, workspace_pin count bump 4→5.
Task 4 — round-trip test raw_buf_module_round_trips, verbatim
structural clone of kernel_stub_module_round_trips.
Task 5 — E2E raw_buf_check_e2e: (con RawBuf (con Int)) consumer
checks clean.
Task 6 — E2E raw_buf_param_in_reject_e2e: (con RawBuf (con Str))
consumer rejected at check with param-not-in-restricted-set.
Task 7 — E2E raw_buf_build_intercept_missing_e2e: (new RawBuf …)
consumer accepted at check, rejected at build with the
existing Term::New deferral message.
Three substantive plan-time decisions resolving plan-recon's
open questions:
1. The intercept-not-registered diagnostic is NOT introduced.
The spec hedged ("intercept-not-registered: new__RawBuf__Int
(or the existing Term::New-deferral diagnostic)") between
shipping a fresh diagnostic and reusing the existing deferral
at crates/ailang-codegen/src/lib.rs:2075-2078. Plan picks
reuse: the deferral already names "milestone raw-buf" and is
self-describing; a new diagnostic would exist for ~1 iter
(raw-buf.2 → raw-buf.3) before going away — disposable infra.
Task 7's test asserts on the substring "Term::New requires
the type's" which is stable in the existing message.
2. In-tree references to crates/ailang-kernel-stub/ AFTER the
rename — split-scope between raw-buf.2 and raw-buf.3.
The path changes in raw-buf.2 (the crate moves now), so
path-references in design/INDEX.md:112 and the CLAUDE.md
Code-layout table get updated in Task 1 Steps 10-11. The
retire-language (stub as "ratifying fixture for kernel-
extension-mechanics" → "retired by raw-buf") stays for
raw-buf.3 close, per spec § Components row 3.
3. parse_raw_buf gets a mirror re-export at ailang-surface/
src/lib.rs:39 alongside parse_kernel_stub. Recon's natural
reading; load-bearing because the new round-trip test calls
ailang_surface::parse_raw_buf() directly.
Plan honours the project's compile-gate discipline. Task 1's
13 steps thread all 8 rename sites inside the same task —
no deferred caller across the build gate. Task 3 bundles the
workspace_pin count bump with the loader injection that drives
it; the assertion goes 4→5 in the same task that makes it true.
Test-count trajectory: 667 (post-raw-buf.1 baseline) → 667
(Tasks 1, 2, 3 — refactor + wiring, no new test) → 668 (Task 4
round-trip) → 669 (Task 5 check E2E) → 670 (Task 6 reject E2E)
→ 671 (Task 7 deferral E2E).
