Second and final iteration of the intrinsic-bodies milestone. Migrates
the 13 authored prelude dummy bodies to (intrinsic), rebaselines the two
hash pins that move, and locks the registry to the source with a
bijection. Behaviour-preserving: the codegen intercepts emit identical
IR; the prelude placeholder bodies were already dead (intercepted by
name before lower_term, since raw-buf.1).
What landed (4 tasks):
Task 1 — examples/prelude.ail: 13 authored dummy bodies → (intrinsic).
7 Eq/Ord instance methods (eq Int/Bool/Str/Unit, compare
Int/Bool/Str) keep their lambda shell (params/ret = the method's
local signature, Design X); the inner (body false)/(body true)/
(body (term-ctor Ordering EQ)) becomes (intrinsic). 6 float_* fns
((body false) → (intrinsic) in the fn body slot). The honesty-rule
infraction the milestone exists to fix is now closed: no prelude
body lies about what runs.
Task 2 — hash rebaselines (the prelude bytes changed):
prelude module hash af372f28c726f29f → 2ea61ef21ebc1913
eq__Int 86ed4988438924d3 → cc7b99b63d1e44ae
eq__Bool d62d4d8c51f433f8 → fd0412f127986512
eq__Str 3d32f377c66b03e0 → fa269285754a52da
compare__Int 6d6c20520766368b → 0a02bd9effc9746c
compare__Bool 02b64e8fadc913eb → d0dc108dacf4e543
compare__Str 9645929d53cd3cc9 → d1419595dc52a456
The 4 show__* mono pins did NOT move (Show bodies are real).
Task 3 — intercepts.rs: registry_contains_all_legacy_arms (one-
directional, hardcoded 18-name list) replaced by
intercepts_bijection_with_intrinsic_markers. The in-source test
walks prelude + kernel_stub pre-mono for Term::Intrinsic markers,
recovers each marker's codegen symbol (mono_symbol(method, type) for
instance methods; the fn name for top-level float_*/answer), and
asserts a bijection over the intrinsic-backed class: (A) every
marker resolves to an INTERCEPTS entry, (B) every INTERCEPTS entry
not on the optimisation-only allowlist has a marker, plus a guard
that the allowlist names are themselves registered. The allowlist is
the 5 *__Int icmp-family entries, which intercept the monomorphised
specialisation of the real-bodied polymorphic lt/le/gt/ge/ne — an
optimisation, not a compiler-supplied body, so no marker. The pin
passing independently confirms Task 1 missed no prelude site.
Task 4 — confirmed no codegen path lowers an intercepted body (already
true since raw-buf.1: try_emit_primitive_instance_body matches by
name before f.body is inspected). Refreshed the now-accurate comment
at lib.rs:1310-1319. design/contracts/0007-honesty-rule.md needed NO
edit — it is a general present-tense rule and does not name the
prelude dummies (confirmed by grep), so editing it would have been
invented work.
Verification:
cargo test --workspace → 669 passed, 0 failed (post-.1 baseline held;
one test replaced net-0).
Behaviour-preservation ratifiers GREEN (the safety net):
eq_primitives_smoke_compiles_and_runs,
compare_primitives_smoke_prints_1_2_3_thrice (e2e.rs);
float_compare_smoke_prints_true_true_false (float_compare_smoke_e2e.rs);
eq_ord_polymorphic_runs_end_to_end (eq_ord_e2e.rs).
Bijection pin GREEN. Both hash pins GREEN at the new baselines.
bench/check.py + compile_check.py → 0 regressed.
Plan-text imprecision (no outcome impact, noted for the record): Task 1
Step 5 wrote `--test e2e` for all four ratifiers, but
float_compare_smoke_prints_true_true_false and
eq_ord_polymorphic_runs_end_to_end live in their own test targets
(float_compare_smoke_e2e.rs, eq_ord_e2e.rs). The verification-filter
self-review checked that the fn names exist, not that they sit in the
named target — a sharper form of the filter-zero discipline. The
implementer ran each in its real target; all four green.
Milestone intrinsic-bodies is now feature-complete (.1 mechanism +
.2 migration+lock). Audit + close follow.
