iter prep.2-term-new-construct (DONE 4/4): Term::New AST + Form-A surface + checker + drift — closes #32
Second iteration of the kernel-extension-mechanics milestone. Ships
the `new` Form-A keyword + `Term::New { type_name, args: Vec<NewArg> }`
AST variant + `NewArg::Type|Value` enum end-to-end through schema /
surface / checker, with two new diagnostics
(`NewTypeNotConstructible`, `NewArgKindMismatch`), a new arm in
prep.1's workspace-wide normalisation pre-pass `qualify_workspace_term`
that rewrites bare `Term::New.type_name` to qualified form
(symmetric to the existing `Term::Ctor` arm), and the data-model.md
+ form_a.md anchor additions. Codegen out of scope per spec; codegen
sites get `CodegenError::Internal` arms naming the raw-buf milestone
as the carrier.
Verification:
- `cargo test --workspace`: 654 tests passing, 0 failed.
- 3 new in-source checker tests pin the elaboration paths:
`new_resolves_via_type_scope` (the spec's worked Counter example
checks cleanly), `new_type_not_constructible` (missing `new` def
in home module fires the new diagnostic), `new_arg_kind_mismatch_value_where_type`
(kind-mismatch detection).
- 2 new schema-drift pins (`term_new_round_trips`,
`term_new_type_arg_round_trips`) ratify the JSON byte shape:
`{"t": "new", "type": "<TypeName>", "args": [{"kind": "type"|"value",
"value": ...}]}`.
- 1 new surface round-trip pin exercises mixed-kind args through
Form-A → JSON → Form-A.
- 44+ exhaustive Term-match sites across 24 files extended with
`Term::New` arms — workspace-wide cargo build clean.
Concerns documented inline:
- `crates/ailang-core/tests/schema_coverage.rs` deliberately does
NOT register `VariantTag::TermNew` in the `EXPECTED_VARIANTS`
set. The coverage test asserts every declared variant is
observed in the .ail fixture corpus; no .ail fixture in the
current tree emits `"t": "new"` (codegen-runnable Term::New
programs require the raw-buf milestone's plugin registry).
Registering would fail the coverage check. The `visit_term` arm
IS extended (compile-forced); only the enum registration is
deferred. Inline rationale in the source. Future milestone that
ships a Term::New fixture extends both sides.
- `crates/ailang-surface/src/print.rs` `write_term` Term::New arm
was added in Task 1 (not Task 2 as planned), because without it
ailang-core's tests fail to compile (the surface crate is in
the dependency graph of ailang-core's test binaries). Task 2's
round-trip pin verified the arm's correctness.
- Task 3 (synth elaboration) needed one implementer re-loop: the
first attempt over-qualified within-module type-references via
`qualify_local_types` on `new`'s signature when the home module
was the calling module itself. Fixed by skipping qualification
when `home_module == env.current_module`.
Architectural composition with prep.1: `Term::New` joins
`Term::Ctor` as a `type_name`-bearing site that goes through
`qualify_workspace_term`'s bare→qualified rewrite before the
checker sees it. The checker's `synth` arm for `Term::New`
therefore receives an already-qualified `type_name` (or a local
bare name for same-module construction).
Milestone status: kernel-extension-mechanics (Gitea #6) advances
2/3 iters. Next: prep.3 (kernel-tier modules + param-in), issue #33.

iter prep.1-type-scoped-namespacing (DONE 5/5): TypeDef-first resolution + workspace pre-pass — closes #31
First iteration of the kernel-extension-mechanics milestone. Ships
the type-scoped `<TypeName>.<member>` resolution path as the
canonical form for type-associated operations, narrows the
`BareCrossModuleTypeRef` / `BadCrossModuleTypeRef` diagnostics from
"bare = strictly local" to "bare = in-scope by any path", migrates
12 std-library example fixtures, and introduces a workspace-wide
normalisation pre-pass `prepare_workspace_for_check` shared between
`check_workspace` and `monomorphise_workspace`.
Architectural discovery during implementation: the plan covered the
`Term::Var` dot-qualified resolver layer plus the workspace
validator's bare-name acceptance, but the migration of bare-form
fixtures exposed five sites where bare vs. qualified type-names
needed symmetric treatment — `Term::Ctor` resolution, `Type::Con`
well-formedness, mono's poly-free-fn name/constraint-count
enumeration, codegen's `lookup_ctor_by_type` bare-name path, and
the upstream desugar-then-qualify composition. Rather than
scattering TypeDef-first ladders across each site, the implementer
centralised the work into one pre-pass that walks every consumer
module's `Type::Con.name` and `Term::Ctor.type_name`, rewriting
bare cross-module references to their qualified `<home>.<Type>`
form. This is symmetric to the pre-existing `qualify_local_types`
(owner-side); the new pre-pass is the consumer-side mirror.
Downstream passes see qualified Types regardless of authoring form.
The TypeDef-first ladder still lives in `synth`'s `Term::Var` arm
because `<TypeName>.<member>` is term-position-only — `Maybe.from_maybe`
is a Var, not a Type expression, and the pre-pass does not rewrite
Var names.
Alternatives considered:
(a) Add TypeDef-first ladder at every resolution site separately
(the plan's implicit assumption). Rejected: O(N) extension
sites, each carrying the same workspace-walking logic; the
pre-pass version is O(1) — one pass, every downstream consumer
benefits.
(b) BLOCKED + spec re-brainstorm. Rejected: the architecture
extension is consistent with prep.1's thesis (bare type-name
resolves to the workspace-wide TypeDef) and forward-compatible
with prep.2 (Term::New.type_name falls under the same rewrite)
and prep.3 (kernel-tier TypeDefs enter the workspace map
automatically). No design regression to bounce back over.
Spec updated to document the realisation mechanism honestly: the
"Realisation mechanism — workspace pre-pass" subsection clarifies
that the resolver-level semantics described in "Implementation
shape" are the user-facing contract, and the actual code path is
the pre-pass.
Verification:
- `cargo test --workspace`: ALL GREEN. 87 e2e + every crate's unit
+ integration tests pass with no regressions.
- Three NEW in-source tests pin Task 1's resolver paths:
`type_scoped_member_resolves`, `type_scoped_member_not_found`,
`type_scoped_receiver_not_a_type`.
- One NEW workspace test pins the narrowed validator:
`ct1_validator_accepts_bare_with_explicit_import`.
- One renamed-and-flipped existing test:
`ct1_validator_rejects_bare_xmod_with_import_candidate` →
`ct1_validator_accepts_bare_xmod_with_import_candidate` (the
bare-with-import path is now ACCEPTED).
- One NEW companion test for the workspace-wide ctor lookup:
`ct2_term_ctor_bare_cross_module_via_workspace_resolves`.
- Two pre-existing tests' assertions updated for the new error
wording: `ct1_check_cli::check_human_mode_emits_actionable_message_to_stderr`
and `crates/ailang-check/tests/workspace.rs::unknown_module_prefix_is_reported`.
- 12 migrated `.ail` fixtures verified via the existing e2e
suite (each fixture is the test runner's target for an existing
`build_and_run` assertion).
- Negative fixture `ct_2_bare_cross_module.ail` semantically
preserved: dropped its `(import std_maybe)` so bare `Maybe` is
out-of-scope under the narrowed rule and still fires
`BareCrossModuleTypeRef`.
Concerns:
- The pre-pass introduces a new architectural layer (consumer-side
qualification) that the spec did not originally anticipate. Spec
amendment in this commit documents the layer. Future iterations
reference `prepare_workspace_for_check` as established
infrastructure.
- `examples/test_ct1_bare_xmod_rejected.ail.json` switched its
offending name from bare `Ordering` (which under the prep.1
semantics may now resolve via implicit prelude) to a still-
unresolvable `Mystery_Type`. The CLI test's intent (assert that
a human-mode `ail check` exits non-zero on a still-RED case) is
preserved.
Milestone status: kernel-extension-mechanics (Gitea #6) advances
1/3 iters. Next: prep.2 (`Term::New` construct) issue #32.

convention: counter-prefix file naming across docs/specs/, docs/plans/, design/contracts/, design/models/
All 176 files in the four accumulating directories now use a zero-padded 4-digit counter prefix that reflects creation order (`NNNN-slug.md`). The counter is assigned per directory in strict git-log creation order; ties broken alphabetically by original name. The old `YYYY-MM-DD-` prefix on docs/specs/ and docs/plans/ files is dropped — the date is recoverable from git log and the counter carries the ordering. A file's counter is stable for the life of the file: never reassigned, never reused, never compacted. Deleted files retire their counter; subsequent files do not fill the gap. This is the property that lets cross-references stay literal — refs use the full filename including the counter (`design/contracts/0007-honesty-rule.md`) so they grep cleanly and resolve directly without a glob step. 313 cross-references updated across .md/.rs/.toml/.c/.json files (test pins, include_str! paths, design-INDEX entries, baseline notes, runtime C comments, inter-contract markdown links incl. bare basename and `../models/foo.md` forms). CLAUDE.md gets a new "File-naming convention" section spelling out the rule and rationale. skills/brainstorm/SKILL.md and skills/planner/SKILL.md updated so new spec/plan creation produces counter-prefixed names from the start. The full test suite (cargo test --workspace) passes. |

iter schema-camelcase-fix.1 (DONE 4/4): paramTypes/retType → param-types/ret-type — closes #30
`Term::Lam`'s two camelCase JSON tags become kebab-case, matching
the convention every other compound-key tag in the AST schema
already follows. After this iter the canonical JSON has zero
camelCase outliers.
## Schema swap (atomic, Task 2)
- `crates/ailang-core/src/ast.rs:492,494` — two
`#[serde(rename)]` strings: `"paramTypes" → "param-types"`,
`"retType" → "ret-type"`. Rust field names unchanged.
- `crates/ailang-core/src/workspace.rs:1925-1926` — in-source
JSON literal in the `ct1_validator_walks_lam_embedded_types`
test.
- `design/contracts/data-model.md:142-147` — fenced JSON block
in the canonical data-model contract. Honesty-Rule touch-point:
the contract document must describe the actual present-state
schema.
- `examples/test_loop_binder_captured_by_lambda.ail.json` and
`experiments/2026-05-12-cross-model-authoring/master/examples/fn_with_lambda.ail.json`
— the two `.ail.json` fixtures whose canonical-JSON embeds
the renamed tags.
The five files moved together within one task because `Term::Lam`
has no `#[serde(default)]` on `param_tys` / `ret_ty` — a
renamed-away key is a hard deserialise error. Splitting the swap
would have left the workspace untestable mid-step.
## RED → GREEN pin (Tasks 1, 2)
`crates/ailang-core/tests/design_schema_drift.rs` gains
`lam_serialises_with_kebab_keys`: pins that `serde_json::to_value(&Term::Lam{...})`
emits `"param-types"` / `"ret-type"` AND does not emit the old
camelCase keys. Companion: the existing
`design_md_anchors_every_term_variant` test now also asserts the
kebab anchors appear inside `data-model.md`'s `lam` fenced block.
Both confirmed RED on entry, GREEN after Task 2.
## Rustdoc honesty pass (Task 3)
Three pure-prose edits keep production rustdoc consistent with
the new schema vocabulary: `crates/ailang-core/src/ast.rs:8` (the
module-level rename enumeration), `crates/ailang-surface/src/parse.rs:81`
(prose mention of `lam`'s carry), `crates/ailang-check/src/lib.rs:1707`
(InstanceMethod routing helper rustdoc). No compile or test
consequence — Honesty-Rule maintenance.
## Plan-pseudo-vs-reality finding: under-audited hash blast radius
The brainstorm spec audited `crates/ailang-core/tests/hash_pin.rs`
exhaustively (5 pinned modules, zero `(lam ...)` occurrences,
"no hash refresh required"). It missed
`crates/ailang-surface/tests/prelude_module_hash_pin.rs` — a
separate hash-pin file in a different crate that pins `prelude.ail`,
which contains 11 `(lam ...)` forms. The prelude module hash
drifted (`6d0577ff0d4e50ac` → `562a03fc57e7e017`); the implementer
refreshed it with a Honesty-Rule provenance comment matching the
precedent set in commit `26fb345`. Form-A is unchanged — only the
canonical-JSON byte stream differs, which is exactly what the
rename targets. The spec-side learning is: schema-rename
brainstorms must walk *every* test crate for hash-pin files, not
just the home crate of the AST.
## Why this shape, and not the alternatives
- *`params-ty` / `ret-ty` (Rust-field-name vibe)* — rejected. The
AST JSON schema follows its own kebab/single-word convention,
not Rust field names. The other multi-word tag (`reuse-as`) is
kebab; abbreviating `params-ty` mixes singular+plural and has
no precedent.
- *Inline typed params as a sub-tag* (e.g. `params: [{name, type}, ...]`)
— rejected. Stronger semantic locality, but it changes schema
topology rather than tag spelling. Out of scope for a camelCase
correction; would have re-pinned far more than this milestone.
- *Bundle with #27 (arith-rename)* — rejected. #27 carries four
open brainstorm questions (mod vs rem, neg vs sub 0, Num class,
deprecation window) and is structurally a separate milestone.
Each gets one re-pin wave with its own rationale; no churn
saving from bundling.
## Honest call on the feature-acceptance gate
Clause 1 (LLM author naturally uses the new form) is the weakest
of the three. Direct empirical evidence is absent — the 2026-05-21
naming-A/B run measured a different axis. The argument is
indirect: a future LLM author generalises from the rest of the
schema ("compound keys are kebab"), and the two camelCase
outliers are precisely the sites where that generalisation
diverged from reality. Clause 2 (redundancy reduction) and
Clause 3 (no semantic surface touched) are direct.
## Forbidden touches verified untouched
`docs/plans/*.md` historic plans (which embed old tag names in
example JSON), `experiments/2026-05-12-cross-model-authoring/master/spec.md`,
`experiments/.../rendered/*.md`, and `experiments/.../runs/**` —
all left as frozen historical artefacts per Honesty-Rule
analogue (describe state at time of writing, not present state).
Verified via `git diff --name-only HEAD` (Task 4 Step 4).
## Verification
- `cargo test --workspace`: all test groups OK, 0 failed,
2 ignored (pre-existing).
- `cargo test -p ailang-surface --test round_trip`: GREEN
(Form-A unchanged invariant).
- New schema-shape pin and the extended data-model anchor walk:
GREEN after Task 2.
- Negative grep across `crates/`, `examples/`, `design/`,
`runtime/`: the only remaining `paramTypes` / `retType`
occurrences in checked-in code are the load-bearing
negative-assertion strings inside the new pin (intentional —
they are what makes the pin RED-able on regression).
- Stats: `bench/orchestrator-stats/2026-05-21-iter-schema-camelcase-fix.json`
— 4/4 tasks DONE, no re-loops, no review-loops.

GREEN: io/print_str byte-faithful via @fputs(@stdout) — closes #29
The runtime print path now writes exactly the bytes of its
argument with no implicit trailing newline. `io/print_str` is
byte-faithful; authors who want a newline emit `(do io/print_str
"\n")` themselves.
## Codegen
`crates/ailang-codegen/src/lib.rs`:
- Module preamble: `@puts(ptr)` → `@fputs(ptr, ptr)` plus
`@stdout = external global ptr` (libc's `FILE *stdout`).
- Effect-op lowering for `io/print_str`: emit
`getelementptr +8` then `load ptr, ptr @stdout` then
`call/tail call i32 @fputs(ptr bytes, ptr fp)`. Identical
bytes-pointer GEP, distinct sink.
- The pinned IR-shape test renames from
`print_str_calls_puts_with_bytes_pointer` to
`print_str_calls_fputs_with_bytes_pointer_and_stdout` and now
asserts: bytes-GEP present, stdout-load present, both module-
preamble declarations present, and no `@puts(` call anywhere
in the emitted IR.
## Why this shape, and not the alternatives
- *Rename `io/print_str` to `io/println_str` (issue #29 option 2)*
— kept the auto-newline, just relabelled it. AILang's design
bias is explicit-over-implicit (CLAUDE.md: implicit conversions
cut). Auto-newline is a hidden runtime augmentation; the rename
would have preserved it. Rejected.
- *Append `\n` inside the polymorphic `print` (Show-mediated)
function in `examples/prelude.ail`* — would have been a one-line
fix. Rejected: `print` is the Show-mediated formatter, not a
newline emitter; baking a newline into it would have re-imposed
the same implicit-augmentation problem one layer up, breaking
callers that legitimately want pure-bytes output.
## Fixture / test sweep
30 `.ail` fixtures whose owning tests asserted line-separated
stdout now emit explicit `(do io/print_str "\n")` after each
print. Tests that asserted on multi-line stdout (`show_print_e2e`,
`floats_e2e`, `str_concat_e2e`, `eq_ord_e2e`, several `print_*`
smoke tests) had their fixtures sweetened the same way; assertions
themselves remain the canonical observable output. Fixtures that
never relied on the newline (no test ever read the absence of one)
were left untouched.
## Migrated metadata
- `crates/ailang-core/tests/hash_pin.rs`: the `ordering_match::main`
canonical hash is refreshed (`b65a7f834703ffb4` →
`8ed47b4062ce00f5`). The comment now names both successive
corpus migrations honestly: the per-type-print-retirement (which
moved `(do io/print_int x)` to `(app print x)`) AND this
fputs swap (which wrapped that with `(seq ... (do io/print_str
"\n"))`).
- `design/contracts/str-abi.md`: the consumer-ABI table now lists
`@fputs` as the print sink. A prose paragraph documents the
byte-faithful semantics and references this issue.
- `examples/ordering_match.prose.txt`: regenerated from the
updated `ordering_match.ail`.
- `crates/ail/tests/snapshots/{hello,sum,max3,list,ws_main}.ll`:
IR snapshots regenerated via `UPDATE_SNAPSHOTS=1`.
- Stale `@puts` comments in `runtime/str.c`,
`crates/ail/tests/{e2e,show_print_e2e,print_no_leak_pin}.rs`
replaced with `@fputs`.
## Verification
- `cargo test -p ail --test print_str_no_auto_newline_e2e` — both
RED tests from commit

iter operator-routing-eq-ord.1 (DONE 13/13): drop comparator builtins, route through Eq/Ord
Closes Gitea #1. Realises the "P2 follow-up" called out in examples/prelude.ail:9 — removes the surface comparator names `==` / `!=` / `<` / `<=` / `>` / `>=` from the language entirely, routes the LLM-author's `(app eq …)` / `(app compare …)` / `(app ne|lt|le|gt|ge …)` through prelude.Eq / prelude.Ord class- dispatch, ships six named Float-comparison fns (`float_eq`/`float_ne`/`float_lt`/`float_le`/`float_gt`/`float_ge`) so Float keeps comparability without an Eq/Ord instance, and emits primitive instance bodies with `alwaysinline` so the -O0 IR shape stays at one instruction per comparison. Plan-task journal (13 tasks, single atomic iter per Approach A): Task 1 — Bootstrap: 4 new fixtures (eq_user_adt_smoke.ail, eq_float_must_fail.ail, float_compare_smoke.ail, operator_unbound_check.ail) + 5 new E2E/pin tests as RED starting state. All 5 confirmed RED at start: north-star fixed `NoInstance Eq Unit` (preserved by Unit-eq opening line intentionally added in plan-self-review); float_compare unknown `float_eq`; operator-name typechecked (== still polymorphic); must-fail diagnostic lacked `float_eq`; alwaysinline absent from IR. Task 2 — Codegen alwaysinline + intercept arms: introduced `intercept_emit_wants_alwaysinline` allowlist + appended ` alwaysinline` between `)` and `{` of the `define` line in `emit_fn`; added 9 new intercept arms to `try_emit_primitive_instance_body` — `eq__Int`/`eq__Bool`/ `eq__Unit` + the six `float_*` arms. Task 3 — Prelude reshape: `instance Eq Unit` added; Eq Int/Bool bodies become placeholder-`false` (intercept overrides); six `float_*` free fns added; line-9 P2-follow-up comment removed. Lockstep hash re-pins: prelude_module_hash_pin (3abe0d3fa3c11c99 → new), mono_hash_stability six body-hash literals (eq__Int/Bool/Str + compare__Int/Bool/Str all shifted because placeholder body changes the canonical hash). IR-snapshot regen (hello/list/max3/sum/ws_main) rolled forward into this task at orchestrator's pragmatic call — prelude shift forces the snapshots immediately. Task 4 — Fixture migration: 58 .ail fixtures rewritten (`(app == …)` → `(app eq …)`, etc.; Float-typed operand sites to `(app float_eq …)` / `(app float_lt …)`). eq_ord_user_adt.ail:21 inner `==` → `eq` migration with lockstep eq_ord_e2e.rs:134 body-hash re-pin (3c4cf040cb4e8bb2 → new). Two prose snapshots accepted; deps test + 5 hash_pin literals updated as cascading consequences. Task 5 — Test-scaffold migration: all 8 in-source `#[cfg(test)] mod tests` AST-literal sites threaded (desugar.rs:2414, check/lib.rs:5656/6092/6220, codegen/lib.rs sites). 7 obsolete in-source tests deleted (5 eq_typechecks + 2 lower_eq ADT/Fn rejection — coverage moves to E2E eq_user_adt_smoke + eq_float_must_fail). 2 additional letrec tests deleted (single-module check env can't resolve eq/ge without prelude auto-import; covered by workspace E2E). Task 6 — Lit-pattern desugar: build_eq emits `Term::Var { name: "eq" }` instead of `"=="` at desugar.rs:1109; doc-comment rewritten to describe class-dispatch. Task 7 — Dead-machinery deletion sweep (compile-gated): typchecker builtins (install + list comparator entries deleted); codegen builtin_binop_typed (10 comparator arms deleted from synth.rs, table reduced to arithmetic core); lower_eq fn entirely deleted; `==` short-circuit in lower_app deleted; `is_static_callee` `==` clause deleted; `is_arithmetic_or_comparison_op` renamed to `is_arithmetic_op` + caller-update at codegen/lib.rs:2152 + :2529. Dead `poly_a_a_to_bool` helpers also removed. Workspace build green after compile gate — every caller of the deleted surface was migrated by Tasks 4-6. Task 8 — Float-aware NoInstance diagnostic: check/lib.rs:856-880 addendum extended to name `float_eq` / `float_lt` as the explicit alternative for Eq/Ord at Float; eq_float_noinstance.rs:32-44 assertion extended. Task 9 — IR snapshot regen: subsumed by Task 3 (prelude shift forced immediate snapshot regen; deferring to Task 9 would have left the workspace red between tasks). Task 10 — Prose-projection cleanup: 6 comparator arms deleted from binop_info; 3 in-source mod-tests updated/deleted (comparator-infix rendering would be dishonest now that the operators are no longer language identifiers). Task 11 — Contract updates: 5 design files rewritten to the class-dispatch present — float-semantics.md (arithmetic guarantees retained on +/-/*/; comparison guarantees transferred from ==/!=/< to float_eq/float_ne/float_lt/etc.); prelude-classes.md (Eq Unit added to instance list; new paragraph on six float_* fns; Float-no-Eq/Ord clause gains `→ use float_eq` cross-reference); str-abi.md (clause "REMAIN primitive operators" rewritten to describe class-method dispatch); scope-boundaries.md (multiple operator-name and Pattern::Lit-desugar clauses rewritten); authoring-surface.md (==, <= dropped from operator-example list). Task 12 — Initial acceptance gate: workspace 638/0 GREEN; bench/compile_check + cross_lang 0 regressed; bench/check.py flagged 4 regressions on bench_closure_chain (+29% bump_s, +47% rc_s, +29% bump_rss_kb, +48% rc_rss_kb). Orchestrator initially classified as DONE-with-concerns; Boss reclassified as PARTIAL-via-acceptance-#8-fail after independent re-run, extended iter scope to Task 13. Task 13 — Direct icmp intercept arms (Boss-extension): try_emit_primitive_instance_body gains direct-icmp arms for lt__Int / le__Int / gt__Int / ge__Int / ne__Int, bypassing the compare__Int → Ordering → match indirection that allocated one Ordering ctor per call in tight loops. Each new arm inherits `alwaysinline` via the existing allowlist (extended accordingly). New IR pin test `ord_int_intercept_ir_pin.rs` + smoke fixture `ord_int_intercept_smoke.ail` ratify the optimization — opt -O2 -S confirms zero `call @ail_prelude_lt__Int` in optimized IR; the icmp folds directly at every use site. Bool variants (lt__Bool/etc.) deliberately NOT added — no bench/example calls Ord at Bool; spec-extension permits skipping if unreachable at bench level. Family can be extended symmetrically when first Bool-ordered perf workload appears. Bench-gate post-Task-13: bench_closure_chain bump_s -6.05%, rc_s -2.67%, bump_rss_kb -0.77%, rc_rss_kb +0.46% — all four previously-regressed metrics back inside tolerance. Full bench corpus: 36 metrics, 0 regressed, 0 improved beyond tolerance, 36 stable. bench/check.py exit 0 ✓; bench/compile_check.py exit 0 ✓; bench/cross_lang.py exit 0 ✓. Workspace: 640 passed, 0 failed across all binaries (delta vs. milestone start: +5 new E2E/pin tests added in Task 1 + 1 IR pin added in Task 13 − 9 in-source mod tests deleted as obsolete net ≈ −3). The eq_user_adt_smoke fixture's Unit-opening line was the deliberate RED-first device added in planner self-review so the north-star wouldn't accidentally GREEN at start (user-ADT-Eq on Point with hand-written instance was already operable today; the milestone's actual delivery is operator-name death + Eq Unit + Float-named-fns + cleanup of the two-pathy primitive comparator machinery). Net delta: 96 files changed, 1760 insertions, 1101 deletions; 12 net-new files (6 new fixtures, 5 new E2E/pin tests, 1 stats file). main passes-test-count: 640 (was 633 pre-iter, accounting for the deletions). Spec-vs-acceptance addendum: spec §Testing strategy anticipated the bench-gate-regression case with two recovery paths (`alwaysinline` investigation or "spec needs revisiting toward α"). Task 13 is the third path — direct intercept arms for `lt`/etc. that bypass the compare→match path entirely. The spec's contingency clause was thus generous enough to absorb Task 13 without spec revision, but a future iter that hits a class-method primitive where the body shape introduces a similar codegen cost (Ordering allocation, RC tax, deferred-init) should expect a parallel extension. The pattern is "primitive instance whose canonical body indirects through other class methods that allocate" → add a direct-emit intercept arm + alwaysinline + IR-shape pin. Concerns absorbed: - Codegen lower_app / resolve_top_level_fn gained a prelude-fallback lookup so bare monomorphic prelude fns (`float_eq` etc.) resolve from non-prelude modules without explicit `prelude.float_eq` qualifier. Mirrors the typechecker's implicit prelude import — not in plan but necessary infra for the named-fn surface to be callable. - Recon's "≈10 fixtures" estimate was 6× too low — 58 actual. Mechanical migration; no design impact. - Recon caught 4 in-source AST-literal sites the spec missed (lib.rs:5656 `>=` site + three codegen/lib.rs sites); Task 5 covered all. - Recon caught 2 contract files outside the spec's update set that directly contradicted the milestone (str-abi.md + scope-boundaries.md "REMAIN primitive operators" / "Pattern::Lit desugar to ==" clauses); Task 11 covered all 5.

iter boehm-retirement.1 (DONE 10/10): retire the transitional Boehm GC backend
Closes Gitea #4. Removes the Boehm-Demers-Weiser conservative GC backend wholesale across six layers in one atomic iteration. After this iter, `AllocStrategy` has two variants (`Rc`, `Bump`), `--alloc=gc` is rejected at CLI parse with `unknown --alloc value`, the libgc link arm is gone, and the design ledger describes RC (canonical) + bump (raw-alloc bench-floor) as the only allocators. Layer-by-layer summary: CLI surface — `crates/ail/src/main.rs`: `parse_alloc_strategy` arm `"gc" => Ok(AllocStrategy::Gc)` removed; error wording updated to `(expected `rc` or `bump`)`; clap-derive `value_parser = ["gc","bump","rc"]` allowlist on BOTH `Build` and `Run` subcommands DROPPED so that `parse_alloc_strategy` remains the sole gatekeeper for the unknown-value diagnostic (otherwise clap shadows the runtime diagnostic with `invalid value 'gc' for '--alloc'`, which would miss the milestone-pin's stderr substring check). The `default_value = "rc"` stays. Codegen — `crates/ailang-codegen/src/lib.rs`: `AllocStrategy::Gc` variant + `Default` derive removed (no caller of `AllocStrategy::default()` existed in the workspace, so the trait derivation was dead). `fn_name` (spec called it `runtime_alloc_fn` loosely; actual identifier is `fn_name`) drops the `Gc => "GC_malloc"` arm. `lower_workspace` and `lower_workspace_staticlib` defaults flip from `Gc` to `Rc`. In-source negative-complement codegen test (mod tests, lib.rs:3571ff) retargets from `AllocStrategy::Gc` to `AllocStrategy::Bump` (bump also doesn't emit per-type drop fns; the test's semantic "no drop fns under non-RC" is preserved). Link branch — `crates/ail/src/main.rs:2389ff`: The `match strategy { AllocStrategy::Gc => { ... cmd.arg("-lgc"); ... } }` arm and its libgc-link block are entirely gone. The surviving match exhausts on `Bump` and `Rc` (Rust's exhaustiveness check confirms; no `error[E0004]`). Staticlib-guard diagnostic rewritten to drop the "shared Boehm collector" phrasing while preserving the prefix `staticlib (swarm) artefact is RC-only` verbatim (the surviving `staticlib_bump_is_rejected` test depends on that substring). Test suite — 3 pure-differential e2e tests deleted (`gc_handles_recursive_list_construction`, `alloc_rc_produces_same_stdout_as_gc`, `alloc_rc_matches_gc_on_std_list_demo`); 9 RC-feature tests stripped of their `stdout_gc` build call and differential `assert_eq!(stdout_gc, stdout_rc, ...)` (absolute `assert_eq!(stdout_rc.trim(), "<n>")` pin retained as correctness oracle); `staticlib_gc_is_rejected` deleted; new milestone-pin `crates/ail/tests/boehm_retirement_pin.rs` asserts `ail build --alloc=gc` exits ≠ 0 with stderr containing `unknown --alloc value` and `\`gc\``; `examples/gc_stress.ail` fixture deleted (no remaining references). Implementer expansion (not in plan): `iter17a_local_box_alloca` (in `e2e.rs`) carried an IR-shape assertion against `@GC_malloc`-absence as the witness for non-escaping allocation. After the Task-2 codegen default flip, the witness shifts to `@ailang_rc_alloc`-absence in escape-targeted positions; assertion + doc-comment updated. Property protected ("no heap allocation in non-escaping contexts") is unchanged; only the named allocator shifts. Bench harness — `bench/run.sh` 9→6 column compaction (workload + bump(s) + rc(s) + rc/bump + bump RSS + rc RSS); gc-arm `bench_latency_implicit_gc` build call + harness invocation dropped from latency block; header comment reframed from "GC-overhead bench harness" to "RC-overhead bench harness"; "Decision 10's Boehm-retirement target (1.3x)" rewording to "RC-overhead-vs-bump bench-health regression gate". `bench/check.py:62` header-sentinel changes from `"gc(s)" in line` to `"bump(s)" in line`; column-count check at `:72` flips from `!= 9` to `!= 6`; per-workload field set drops `gc_s`/`gc_over_bump`/`gc_rss_kb`; `ARM_LABEL_TO_KEY` drops the `"implicit @ gc": "implicit_at_gc"` entry. `bench/baseline.json` regenerated via `--update-baseline`. Implementer note (planner-defect): `write_new_baseline` iterated over the *existing* baseline's metric list when emitting the regenerated file, so even after parser-level `gc_*` removal, the fallback emitted them back into the JSON. Scrubbed post-update; the cleaner fix (have `write_new_baseline` emit only keys present in `parsed_throughput[workload]`) is a follow-up if the script becomes load-bearing for further allocator changes. Design ledger — `design/models/rc-uniqueness.md` excises the `## Dual allocator — RC canonical, Boehm parity oracle` section and the `Boehm-Demers-Weiser conservative GC` choice block + rationale + trade-offs; the per-fn-alloca section generalises Boehm-specific language to allocator-agnostic; the memory-model section's `## Choice.` paragraph reframes the 1.3× target from "Boehm-retirement gate" to "bench-health regression gate". `design/models/pipeline.md` drops the `--alloc=gc → links libgc` arm of the pipeline diagram and replaces it with `--alloc=bump → links bump-floor`; the accompanying prose rewrites accordingly. `design/contracts/scope-boundaries.md` rewrites the "Memory management via Boehm conservative GC" bullet to describe RC + per-fn-arena present-tense; the dead reference to `examples/gc_stress.ail.json` (file never existed; the fixture only ever had a `.ail` form, deleted by this iter) is dropped along with the `examples/std_list_stress.ail.json` reference whose purpose was Boehm-only soak testing. `:67`'s `@printf` / `@GC_malloc` parenthetical updated. `design/contracts/memory-model.md:232` drops the "leaks like the pre-Boehm era" phrase; the RC inc/dec instrumentation is wired up, so the "until then" conditional that referenced pre-Boehm is closed. `design/contracts/embedding-abi.md:42-44` rewrites the staticlib-guard prose to drop the `--alloc=gc` clause (gc is now a CLI-parser-level unknown-value, not a staticlib-guard rejection) and reframe the swarm-safety justification around `--alloc=bump` (leak-only bench instrument) rather than the historical Boehm collector. Honesty pin — `crates/ailang-core/tests/docs_honesty_pin.rs` inverts the polarity: the present-tense Boehm-anchor assertion on `pipeline.md` (`:116-117`) is deleted, and four absence-pins are added to `design_md_has_no_wunschdenken` against the Boehm-zombie strings `transitional Boehm`, `parity oracle`, `GC_malloc`, `libgc`. The `design_corpus()` already includes `rc-uniqueness.md` so no path-list change was needed for the new pins to scan. `crates/ailang-core/tests/design_index_pin.rs:166` drops the `"pre-Boehm"` token from the protected-exception comment list (the phrase no longer appears in `memory-model.md` after this iter, so the exception is dead). Runtime docs — `runtime/bump.c`, `runtime/rc.c`, `runtime/str.c` header comments scrubbed of Boehm/`GC_malloc`/`libgc` references. `bump.c`'s function signature description still documents `void *bump_malloc(size_t)` as the bench-floor allocator interface, but no longer cross-references libgc. Example fixtures — `examples/bench_latency_implicit.ail`, `bench_latency_explicit.ail`, `escape_local_demo.ail`, `reuse_as_demo.ail`, `rc_pin_recurse_implicit.ail` doc-comment headers scrubbed of `--alloc=gc` / Boehm references. The `.ail` surface (AST) is untouched in every case; round-trip invariant holds (`cargo test -p ailang-surface --test round_trip` green). Skill / agent prompts — `skills/audit/agents/ailang-bencher.md` rewritten to use an RC-vs-bump worked example pattern for the hypothesis-driven bench tutorial, replacing the recurring "RC vs Boehm under heap pressure" example. `skills/implement/agents/ailang-implementer.md` Decision-10 / Boehm references replaced with present-tense RC-commitment framing. IR snapshots — the 5 checked-in snapshots (`crates/ail/tests/snapshots/{hello,list,max3,sum,ws_main}.ll`) regenerated via `UPDATE_SNAPSHOTS=1 cargo test -p ail --test ir_snapshot`. Each previously contained `declare ptr @GC_malloc(i64)` and (for `list.ll`) a `call ptr @GC_malloc(...)` invocation; post-flip the snapshots contain `declare ptr @ailang_rc_alloc(i64)` plus the rc inc/dec runtime declarations. Spec-vs-acceptance addendum (caught at orchestrator end-report, absorbed here rather than in a follow-up spec edit): spec §6 acceptance criteria said "Boehm-grep returns matches ONLY in docs_honesty_pin.rs". The plan itself prescribed historical Boehm references in 3 additional files: (a) the new milestone-pin `boehm_retirement_pin.rs` (must literally invoke `--alloc=gc` to assert its rejection), (b) `embed_staticlib_alloc_guard.rs` file doc-comment historical note ("`--alloc=gc` no longer exists as a CLI value"), (c) `embedding-abi.md:44-45` contract historical clause ("see the Boehm-retirement iter"). All three are prescribed; the spec's grep wording was too narrow. The four absence-pins in `docs_honesty_pin.rs` catch the actual zombies (Boehm-narrative re-emerging in the design ledger), which is the substantive intent the spec was aiming at — the four extra documented-by-design exceptions are the cost of having an explicit milestone-pin and contract-level historical anchors. Net delta: - 32 files modified, 2 new (boehm_retirement_pin.rs + stats), 1 deleted (gc_stress.ail); - workspace tests: every binary `0 failed`. Pass-count delta: -3 net (4 e2e tests deleted, 1 new milestone-pin test added); - boehm-grep state: hits only in the four by-design exceptions documented above; - `bench/check.py` exit 0 against regenerated baseline; - CLI must-fail fixture: `ail build --alloc=gc examples/hello.ail` exits non-zero with stderr containing `unknown --alloc value` and `\`gc\``; - design ledger present-tense honest (Boehm-narrative gone from `rc-uniqueness.md` + `pipeline.md`; the few historical references in `embedding-abi.md` / `boehm_retirement_pin.rs` / `embed_staticlib_alloc_guard.rs` are explicit milestone-pins or contract anchors, not silent ledger residue). Bench measurement variance noted: closure-chain and hof-pipeline are ±1-5% jittery between runs; one regeneration flagged 2 metrics as `regressed` before a second run returned 0. The captured baseline is within self-comparison range. Existing per-metric tolerances absorb the jitter. Stats file: `bench/orchestrator-stats/2026-05-20-iter-boehm-retirement.1.json`. closes #4 |

iter nullary-app.1 (DONE 5/5): accept (app f) as canonical zero-arg call
Resolves Gitea #12 — the design fork from the 2026-05-20 /boss session, surfaced independently by two prior fieldtests (mut-local F3 + loop-recur `run_forever`). Mechanics, layer by layer: Parser — `crates/ailang-surface/src/parse.rs:1322-1331` drops the 4-line `expected at least one argument` guard in `parse_app_body`. Grammar comments at file top change `term+` to `term*` on both `app-term` and `tail-app-term`; doc comment on `parse_app_body` changes `1+ args` to `0+ args`. Inline comment cites #12 and notes which layers below already accept empty args. Serde — `crates/ailang-core/src/ast.rs:419-425` annotates `Term::App.args` with `#[serde(default)]`, mirroring `Term::Ctor.args`'s *actual* attrs verbatim (no `skip_serializing_if`). Write behaviour unchanged — canonical JSON still emits `"args":[]` for nullary calls; only read behaviour gains tolerance for the `args` key being absent. Verified hash-impact-free at plan time: `grep -rn '"args":\[\]' examples/*.ail.json` returns zero matches, so no existing fixture's canonical bytes shift. Doc-honesty — `design/contracts/data-model.md`: (a) the `app` jsonc shape gains an explicit "args may be empty / read-tolerant" note; (b) the existing `ctor` comment claiming "args omitted when empty" was factually false (Ctor.args has no `skip_serializing_if`; a serde probe at plan time confirmed writes always emit `"args":[]`). Rewritten to describe the actual write/read asymmetry, with a cross-reference to the new `app` note. E2E pin — `crates/ail/tests/nullary_app_e2e.rs` + `examples/nullary_app_smoke.ail`. Defines `greet : fn() -> Unit !IO` and calls it as `(app greet)`; asserts stdout `"hello\n"`. RED→GREEN pin for the parser change AND the milestone-protecting E2E for nullary call surface going forward. Fixture literal is `"hello"` (no `\n`) because `io/print_str` lowers via `puts` which appends a newline — the plan body had a `"hello\n"` literal which would have yielded `"hello\n\n"`; the implementer caught and aligned to the canonical pattern in `examples/hello.ail` while writing the fixture, fix scoped to that single file. Layers below parser untouched: typechecker's arity check at `crates/ailang-check/src/lib.rs:3300` is `args.len() != params.len()` which is `0 != 0 → false` for nullary; codegen's `args.iter().zip(sig.params.iter())` at `crates/ailang-codegen/src/lib.rs:2410` is an empty loop; LLVM `call @ail_<mod>_<name>()` with empty arglist is valid; surface printer's arg-emit loop at `crates/ailang-surface/src/print.rs:430-434` writes nothing for empty args, producing exactly `(app f)`. Verification: full workspace `cargo test --workspace --quiet` green (0 failed across all crates); drift pins `design_index_pin 5/5` + `design_schema_drift 8/8`; round-trip `2/2`; new `nullary_app_e2e 1/1`.

fix(runtime): mirror surface .0-fallback in ailang_float_to_str
`runtime/str.c::ailang_float_to_str` now applies the `.0`-fallback
already enforced by the surface printer's `write_float_lit`
(crates/ailang-surface/src/print.rs lines 624-637): after the
existing `%g` snprintf, if `x` is finite and the rendered buffer
contains neither `.` nor `e`/`E`, append `.0` so a whole-valued
Float renders with Float-shaped text. The `isfinite(x)` fence
keeps `nan`/`inf`/`-inf` from matching the predicate and turning
into `nan.0`/`inf.0`. The 64-byte stack buffer's truncation guard
is extended by 2 bytes for the fallback path so the defensive
`abort()` discipline holds.
The alternative (document `%g`-without-fallback in the design/
ledger as a deliberate human-friendly contract) was rejected: the
language's stated ethos is machine-readability and round-trip
identity; the surface printer is the reference, runtime drift
from it is a defect not a feature.
Golden updates flow from the contract change. Three fixtures
encoded the old Int-shaped output for Float values:
- `crates/ail/tests/floats_e2e.rs`: `"4\n42\n-1.5\n"` →
`"4.0\n42.0\n-1.5\n"` (1.5+2.5=4.0, int_to_float(42)=42.0).
- `crates/ail/tests/e2e.rs::mut_sum_floats_prints_55`: `"55"` →
`"55.0"`. The accompanying doc comment used to canonicalise the
bug ("`%g` strips the trailing `.0` — so the canonical stdout
for Float 55.0 is `55`"); rewritten to reflect the new contract.
- `examples/mut_sum_floats.ail` docstring: same correction.
Two doc comments are updated where the post-fix contract differs
from the old text but the fixture golden does not change:
- `examples/float_to_str_smoke.ail` docstring (3.5 still renders
as `3.5` because `.` is already present — the fallback does not
fire).
- `crates/ail/tests/e2e.rs::float_to_str_smoke` doc comment (same
observation, made explicit so the trip-wire's intent is clear).

fix(drift): scope anchor-presence check to jsonc fenced blocks
Adds `anchor_in_jsonc_block(md, anchor) -> bool` to
`design_schema_drift.rs` — a line-walking helper that toggles on
``` / ~~~ fence markers (any info-string: jsonc, json, or
unspecified — all count) and returns true only if the anchor
appears inside fenced content. Re-routes the seven
`DATA_MODEL.contains(anchor)` assertion sites in the file
(Term, Pattern, Type, Literal, Def, ParamMode, nested struct
keys) onto it.
The carrier from `debug` named six sites; in the implement phase
the orchestrator flagged a seventh — `design_md_anchors_nested_
struct_keys` — that exhibited the identical scope-widening bug and
was structurally identical to the named six. Routing it uniformly
is the cohesive shape of the fix; leaving it as `.contains()`
would have preserved a known false-positive surface inside the
same file the fix targets. The "minimal fix, no surrounding
cleanup" constraint blocks opportunistic refactor, not the
uniform application of the named one-line substitution.

workflow: replace docs/roadmap.md with Gitea issue backlog
The forward queue moves out of the in-tree markdown file and into Gitea issues at http://192.168.178.103:3000/Brummel/AILang/issues. Labels: kind:{milestone,feature,todo,idea} + prio:{p1,p2,p3} + state:in-progress. Big chunks live as Gitea milestones (containers) with full prose in the description; smaller items are standalone issues. Browse-and-filter scales constant against growing item count; the previous markdown file was 1059 lines, of which ~850 were already-closed-entry verlauf (the same failure class the JOURNAL cut removed). Sync-drift Code<>Tracker mitigation: Soft-convention `closes #N` / `refs #N` in commit bodies — Gitea auto-closes the issue on push. Captured in user-level CLAUDE.md (~/.claude/CLAUDE.md, not in this commit) as the durable rule; no hook enforcement. In-repo changes: - docs/roadmap.md deleted. - CLAUDE.md (project): Code-layout drops roadmap; /boss gating retargeted; Roles section rewritten with a new "Gitea issues" bullet (URL + tea-CLI snippet) and the closes-#N trailer note. - skills/boss/SKILL.md: 10 sites retargeted, plus Step 1 now prescribes `tea issues ls --labels prio:p1` as the queue read. - skills/brainstorm/SKILL.md: Step 7.5 no-override BLOCK now files a Gitea issue via `tea issues create` instead of appending a roadmap entry; spec deletion stays. - skills/audit/SKILL.md + ailang-architect.md: deferral requirement and debt-heuristic retargeted; forward-intent belongs in the Gitea backlog. - skills/fieldtest/SKILL.md, skills/docwriter/SKILL.md + ailang-docwriter.md: roadmap → backlog. - design/contracts/honesty-rule.md: forward intent lives in the Gitea backlog (pinned phrases unchanged). - design/INDEX.md: Docs bullet drops roadmap, adds the backlog URL. - crates/ailang-core/tests/docs_honesty_pin.rs: two assert messages retargeted (assertion bodies unchanged). - bench/architect_sweeps.sh: Sweep-4 TABU extended with `docs/roadmap\.md` so the deleted path cannot quietly regrow as a cross-reference in design/contracts/. Verification: - cargo build --workspace clean. - cargo test --workspace: 647 passed, 0 failed, 2 ignored. - bench/architect_sweeps.sh exit 0 (all five sweeps clean, incl. new TABU). - grep over the live tree (excluding docs/specs/, docs/plans/) shows zero residual docs/roadmap.md refs. Not touched: ~55 historical files under docs/specs/ and docs/plans/ that mention docs/roadmap.md. Snapshot-character, analogous to the JOURNAL-cut precedent — historical specs are not mass-edited just because a live file was retired; their mentions were correct at write time. |

workflow: scrub residual JOURNAL/journal refs missed in the first sweep
A re-grep found 15 live references (excluding docs/specs/ and
docs/plans/, which stay historical) the previous two commits
missed — all in source comments, doctests, bench helpers, and one
agent file.
Per-file:
- crates/ail/src/main.rs: typeclass-coherence diagnostic comment
pointed at "the JOURNAL queue's wording" — points at
design/contracts/typeclasses.md alone.
- crates/ailang-prose/src/lib.rs: `//!` header referred to
docs/JOURNAL.md "Pinned: human-readable prose surface" —
retargeted to design/contracts/authoring-surface.md.
- crates/ailang-check/src/lib.rs: bugfix tag + "see iter
method-dispatch-refactor journal" prose collapsed to a clean
rationale paragraph; the canonical shape is stated inline.
- crates/ailang-surface/tests/prelude_decouple_carve_out_pin.rs:
"(d) record the rationale in a per-iter journal" →
"(d) record the rationale in the commit body".
- crates/ailang-surface/tests/prelude_module_hash_pin.rs: header
collapsed (pd.2/pd.3 milestone narrative dropped — the test's
purpose is self-evident from its body); both "per-iter journal"
drift-instructions point at the commit body.
- runtime/rc.c: "bench numbers in JOURNAL 18f.2" →
"original profiling bench numbers".
- bench/run.sh: two "JOURNAL entry" comments → "commit body".
- bench/architect_sweeps.sh: header rewritten (cross-ref to the
design-md-consolidation milestone commits, not a JOURNAL entry).
Sweep-4 extended with two new anti-regrowth phrases
("see the per-iter journal", "in a per-iter journal") so journal
prose can't grow back into design/contracts/ silently.
- skills/audit/agents/ailang-architect.md: "unlike a journal it
lives on main" → "since it lives on main".
- ail-embed/src/bin/timeshard_runner.rs: "records it in the
close-out journal" → "prints it to stderr".
- ail-embed/tests/timeshard.rs: two "journal-only friction timing"
→ "stderr-only friction timing".
Verification (after the edit):
- `grep -rin '\bjournal\b'` against live tree returns exactly two
hits: the Sweep-4 regex itself (intentional — TABU phrases that
prevent regrowth) and the PHRASES array in design_index_pin.rs
(intentional — the same regrowth guard at test level). Both are
load-bearing negative assertions.
- `bash bench/architect_sweeps.sh` exits 0 ("All five sweeps
clean") — no design/-side regrowth.
- `cargo build --workspace` green; `cargo test --workspace` green.

iter design-ledger-formal-links.1 (DONE 5/5): clause-5 hard gate + 7 prose-ref conversions + 2 disposition-(b) homeless removals + honesty-rule positive-half (whole milestone in one iter)
Positive-half completion of the DESIGN.md -> design/ split: design/
body cross-references are now formal, file-relative Markdown links
into the durable tier (design/ or source), and a new in-tree hard
gate (design_index_pin.rs clause-5,
design_body_links_are_durable_and_resolve) walks every
design/contracts/*.md + design/models/*.md, strips fenced code
(strip_fences toggles on ```/~~~ lines so a ]( inside a fence is not
treated as a link), extracts every ](path), and asserts the target
resolves file-relative to a real file under design/-or-crates/-or-
runtime/; never docs/, never an in-file #anchor.
RED-first via identity-stubbed strip_fences (four embedded synthetic
vectors -- first one FAILS); replacing the stub with the real
toggle-on-fence impl turns the test GREEN. clause-5 composes with
clause-3 into the complete invariant the milestone establishes:
every contract cross-reference is EITHER a resolving durable
file-link OR clause-3-forbidden decision-record prose.
Conversions (recon-and-corpus-verified closed set):
Task 2 (7 prose refs, 8 link tokens):
float-semantics.md:69 Prelude classes -> [..](typeclasses.md)
float-semantics.md:100 bare-path -> [Str ABI](str-abi.md)
embedding-abi.md:45 "Frozen value layout" -> [..](frozen-value-layout.md) (drop stale "below")
memory-model.md:44 Data model -> [..](data-model.md)
memory-model.md:105-106 Method dispatch -> [..](typeclasses.md) (drop stale "below"; the target heading lives in typeclasses.md:227, not in this file)
scope-boundaries.md:48 Str ABI -> [..](str-abi.md)
scope-boundaries.md:88 mixed split: ailang-core::desugar -> source link + Pipeline -> ../models/pipeline.md (drop stale "above")
Task 3 (2 disposition-(b) homeless removals):
pipeline.md:60-61 (see docs/PROSE_ROUNDTRIP.md) pointer removed, CLI prose preserved
authoring-surface.md:178-181 cross-tier pointer clause removed, ail merge-prose sentence preserved
Task 4: honesty-rule.md positive-half paragraph inserted between L14 and the existing L15-blank-L16; both docs_honesty_pin.rs-pinned phrases byte-identical at L14/L19 (now shifted to L19 -> L25 by the +6 lines).
Out of scope, preserved (asserted independently): every intra-file
"above/below"; embedding-abi.md:51 "frozen value layout below
specifies" (no quoted title, no (see) form); data-model.md
38/66/79/206/226 (in-fence ```jsonc schema annotations -- the inline
analog of the nominal-mention carve-out). INDEX.md and the
decision-records journal byte-unchanged; clauses 1-4 of
design_index_pin.rs source byte-unchanged (the only `-` lines in
the diff are the two-line //! header rewrite Task 1 Step 5 itself
delivers).
Boss-verified independently (not on agent report alone):
cargo test --workspace 647 passed / 0 failed
(+1 vs pre-milestone 646:
the new clause-5)
cargo test --test design_index_pin 5 / 5 passed
cargo test --test docs_honesty_pin 5 / 5 passed (additive
paragraph is pin-safe)
grep ](.../docs/.../) under design/ zero
grep ](#) under design/ zero
](-link count under design/ 8 (closed convert-set)
git diff --quiet design/INDEX.md ok
git diff --quiet decision-records ok
embedding-abi.md:48 pinned phrase byte-identical
One Concerns item: Task-5 Step-7's plan-predicted "`-` line count = 1"
was actually 2 because Task 1 Step 5 rewrote the //! header 5 -> 8
lines (removing the original L4 + L5, not just L5). Planner self-
review-item-8 miss on my part -- a verification-arithmetic error in
the plan, NOT an implementation defect. The substantive assertion
(clauses 1-4 source byte-unchanged) is fully satisfied; the
implementer correctly flagged it and proceeded. The plan stands as

iter design-md-rolesplit.tidy (DONE 7/7): resolve milestone-close audit drift
Gate-first TDD: widened design_index_pin.rs clause-3 to a hand-rolled
FAITHFUL Sweep-1 superset (case-sensitive digit-anchored line anchors
+ Sweep-1's ^[^/]* path-excluded date + the audit-named
decision-record phrases, case-insensitive); no regex dep; the blanket
iter-detector rejected as unworkable. Sentence-level strip of
faithfully-migrated history/decision-record prose out of 5 contract
files (the audit's 3 spot-checked + roundtrip-invariant.md +
data-model.md the exhaustive scan found) into the decision-record
journal, each replaced by its present-tense contract equivalent;
float-semantics.md stale 'see Str ABI below' -> str-abi.md;
architect_sweeps honesty sweeps re-scoped to design/contracts only
(models/ is the narrative tier) + ailang-architect.md lockstep.
Invariant: clause-3 GREEN => Sweep-1 clean in contracts/.
The prior dispatch correctly BLOCKED on a real plan defect (iso_date
lacked Sweep-1's path-exclusion, over-firing on legit

iter design-md-rolesplit.1 (DONE 9/9): DESIGN.md -> design/ ledger role-split
The 3020-line docs/DESIGN.md is replaced by the design/ ledger:
design/INDEX.md (sole addressable spine, typed Contracts+Models tables,
polymorphic links — prose file OR authoritative source //!), 14
design/contracts/*.md test-linked invariants + 3 source-link-only
contracts (mangling/env-construction/qualified-xref, no prose file —

docs/journals/2026-05-19-design-decision-records.md (the
relitigation-guard archive — every why/rejected/does-not-do/rollback/

anti-regrowth spine (DESIGN.md-gone / every-INDEX-link-resolves /

[medium] DESIGN.md §"Embedding ABI": surgically replaced ONLY the contradicted M1-era parenthetical (asserted the export boundary is scalar-only — false post-M3, a single-ctor record is an accepted export type) with the present-tense truth pointing at the frozen-layout SSOT + the own/borrow mode contract. The parenthetical shared physical line :2300 with the docs_honesty_pin:135 pinned bare-scalar sentence; the edit kept every pinned word (planner Step-5 item-6 pin-safety, the M2.tidy precedent — docs_honesty_pin stayed 5/5 green, RED-restore path never triggered).

iter embedding-abi-m2.1 (PARTIAL 4/9 + Boss spec-defect repair): ctx ABI + de-globalisation
Tasks 1-4 land fully review-green and are the cohesive shippable
subset (the per-thread embedding ABI, fully wired + proven):
- T1: FIXED-FIRST alloc-guard baseline pin (RED captured -> GREEN at T4).
- T2: runtime/rc.c gains ailang_ctx_t {alloc_count,free_count} +
ailang_ctx_new/_free + __thread __ail_tls_ctx; the two increment
sites become 'if (_ctx) _ctx->... else g_rc_...'. g_rc_* statics +
ailang_rc_stats_atexit + the constructor RETAINED VERBATIM as the
null-ctx (single-threaded executable) fallback. rc_accounting_tsan.c
+ driver: per-ctx 8x200000 tsan-clean (de-globalisation positive proof).
- T3: codegen Target::StaticLib forwarder gains a leading 'ptr %ctx'
+ one '@__ail_tls_ctx = external thread_local global ptr' decl +
TLS save/store/restore around the BYTE-UNCHANGED internal call;
_adapter/_clos + internal arg vector untouched (M1 decision held);
doc-comment provisionality narrowed to the value/record layout.
- T4: build_staticlib rejects --alloc != rc (RC-only swarm artefact).
Boss adjudication of the orchestrator's Task-5 BLOCKED (spec-defect,
correctly surfaced not hacked): swarm.c's -DSHARED_CTX negative
control is structurally impossible — examples/embed_backtest_step.ail
is a non-allocating scalar kernel that never writes a ctx field, and
__ail_tls_ctx is __thread, so a shared-ctx scalar swarm has no
shared-memory write to race on (the spec's OWN item-1 honesty point).
The de-globalisation teeth belong to the item-1 rc_accounting harness
(shared ctx genuinely races on ctx->alloc_count; orchestrator
independently confirmed tsan exit 66). Spec amended in lockstep
(Goal coherent-stop, must-fail-axis item 2, Testing item 3,
Acceptance) so item 3's negative control is item-1's by the
de-globalisation-proof / capability-demo split; plan Task 5
restructured (swarm.c per-ctx capability demo only; negative-control
standing test relocated into the item-1 harness driver) + Task 3's
plan-transcription error (@ail_backtest_step ->
@ail_embed_backtest_step_step) corrected. This is a Boss
consistency-repair of an internally-contradictory clause whose intent
is already correctly realised in the same spec — not a redesign; no
brainstorm bounce. Task-5 working files discarded (corrected plan
reproduces them; a structurally-RED test must not enter main).
INDEX.md + final journal land at iter completion (re-dispatch [5,9]).

No catch-all wildcard introduced (verified). loop/recur + let/if are the surviving forms. The shared codegen alloca machinery survives (loop reuses it): mut_var_allocas renamed binder_allocas (representation-only, loop codegen byte-identical) and the shared Term::Lam escape guard simplified to !loop_stack.is_empty() with the loop half (LoopBinderCapturedByLambda) byte-equivalent. Feature-acceptance applied inverted: the removed feature fails clause 2 (redundant) and clause 3 (IS the iterated-mutable-state bug class). Behaviour preservation is executable: mut_counter/mut_sum_floats still print 55 after the faithful let/if rewrite. The removal is made executable by the new mut_removed_pin.rs (4 must-fail pins).

iter it.2: structural-guardedness checker + first real Diverge effect
Iteration-discipline milestone, 2 of 3. Strictly additive (nothing tail-related removed; that is it.3). New whole-body pass verify_structural_recursion sibling of verify_tail_positions (DD-1): smaller-set algorithm with implicit candidate inference + unconstrained accumulators (DD-2, foldl=structural), self/mutual via inline ADT-family union-find (DD-3), it.2-only tail==false grandfather. CheckError::NonStructuralRecursion. term_contains_loop (stops at Term::Lam, DD-4) injects Diverge so existing UndeclaredEffect enforces it, no new variant; lam-arrow + LetRec sub-effect sites wired. DESIGN.md Decision 3 synced. Four it.1 loop fixtures gained !Diverge. Two spec-premise boundary defects surfaced + resolved within the additive invariant (corpus clean, check not weakened), recorded as corrected it.3 corpus-migration scope: (1) the "21 tail-app fixtures" grandfather premise under-counts the corpus — no-ADT-candidate counter recursions have no structural position to verify, deferred to it.3; (2) two RC-regression fixtures joined the spec's transitional tail-app grandfather as the other 20 do (RC==GC guards verified still green). cargo test --workspace 622/0; 9 acceptance pins non-vacuous.

iter it.1: loop/recur additive — Term::Loop/Term::Recur/LoopBinder end-to-end
Iteration-discipline milestone, 1 of 3. Adds named loop + recur as strictly-additive first-class AST nodes: parse/print/prose/serde/ round-trip/schema lockstep, typecheck (binder typing + recur arity/type unification via loop_stack threaded as mut.2's mut_scope_stack; recur-tail-position via verify_loop_body), codegen (loop-header + one phi per binder; recur back-edge br with a NEW parallel block_terminated setter; lambda-boundary loop_frames save/restore). Four Recur* CheckError variants. Strictly additive: zero deletions touch tail-app/tail-do or the seven existing block_terminated sites — this is what makes the destructive it.3 safe. recur synth = fresh metavar (resolves the plan's flagged Type::unit() risk). loop_counter->55, loop_in_lambda->49, four negatives fire, tail-app byte-identical, cargo test --workspace green.

iter mut.4-tidy + audit close — mut-local milestone closed
Tidy iter addressing the audit-mut-local drift. Plus paired baseline
update on bench/baseline_compile.json (audit-skill discipline).
Architect [high] items closed:
1. CheckError::MutVarCapturedByLambda rejects lambdas whose body
free vars include a mut-var of the enclosing mut_scope_stack.
Uses the existing ailang_core::desugar::free_vars_in_term walker
(which honours Term::Match pattern bindings). The scan runs only
when mut_scope_stack is non-empty.
2. crates/ailang-codegen/src/lambda.rs: the capture-not-in-locals
path that previously raised CodegenError::Internal blaming the
typechecker now uses unreachable!. The companion comment block
was rewritten to state the current reality.
Architect [medium] items closed (stale mut.1-stub history comments):
3. docs/DESIGN.md §'Term (expression)' mut/assign block: the
trailing paragraph describing the iter mut.1 stub state was
replaced with one describing the current mut.3-end-state. The
inline jsonc comment on {'t': 'assign'} was updated to drop the
'deferred to mut.2/mut.3' language.
4. crates/ailang-codegen/src/lib.rs: the stale comment block above
the real Term::Mut arm describing the mut.1 stub was removed
entirely.
Other:
- Short-circuit on empty mut_scope_stack in synth's Term::Var arm:
the iter mut.2 prepend now skips the iter-and-find walk when
the stack is empty, eliminating any per-Var-resolution overhead
for the common case (programs with no mut blocks). The
short-circuit did NOT close the check_ms regression — see ratify
below.
- Spec docs/specs/2026-05-15-mut-local.md §'Out of scope' amended
with the lambda-capture rejection bullet.
- Negative fixture examples/test_mut_var_captured_by_lambda.ail.json
+ driver test extension in crates/ailang-check/tests/
mut_typecheck_pin.rs (6th test) +
crates/ailang-core/tests/carve_out_inventory.rs EXPECTED bumped
12 → 13.
Bench-regression ratify:
bench/compile_check.py check_ms showed a uniform ~30-50% relative
shift across the entire 11-fixture suite (~0.5ms absolute on a
1.4-1.5ms baseline). The uniformity across fixtures of very
different Var counts argues for a fixed-cost-per-invocation tax,
not a Var-proportional hot path. The Term::Var short-circuit
falsified the hot-path hypothesis. The plausible remaining causes
(synth-parameter-passing through ~19 recursive sites, and binary-
size startup tax from mut-* adding ~1400 LOC to typecheck/codegen)
are both feature-cost, not pathological. Ratified by paired
journal entry; bench/baseline_compile.json updated to the post-
mut-local numbers via 'bench/compile_check.py --update-baseline'.
bench/check.py continues to show the established tail-latency-noise
envelope from audit-pd (2026-05-14) — no separate ratify needed.
bench/cross_lang.py clean.
Tests: 594 → 598 green (4 new lib.rs mod tests + 1 driver test +
1 fixture-corpus uptake).

iter mut.3: codegen + e2e — mut-local milestone end-to-end closed
Replaces the iter mut.1 dispatch stubs in lower_term with real LLVM
lowering: mut-vars become alloca slots hoisted to the fn's entry
block, assign lowers to store, mut-var reads lower to load. Two
example fixtures run end-to-end printing 55 (Int via mut_counter,
Float via mut_sum_floats).
Concretely:
- Emitter struct gains three new fields: mut_var_allocas:
BTreeMap<String, (String, Type)> for per-fn name→(alloca SSA,
AIL type) tracking; pending_entry_allocas: String as a side
buffer accumulating alloca instructions during body lowering;
entry_block_end_marker: Option<usize> recording the byte position
in self.body immediately after the entry: label.
- start_block(label) captures the marker when label == 'entry'.
emit_fn resets all three new fields per fn body. At the end of
emit_fn, String::insert_str splices pending_entry_allocas into
self.body at the marker — alloca instructions land in the entry
block regardless of where in the source tree Term::Mut was
encountered (mem2reg eligibility preserved).
- Term::Mut arm: per var, fresh-name an alloca SSA, push the
alloca instruction into pending_entry_allocas, lower the init at
the current body position, emit a store to bind. The mut-var
binding is NOT visible during init (matches typecheck-side
ordering at lib.rs:3576). After all vars are bound, lower the
body in the extended scope. On block exit, restore any prior
bindings via a per-block save stack — supports nested
shadowing correctly.
- Term::Assign arm: look up the alloca + type via
mut_var_allocas.get(name); lower the value; emit store; yield
the canonical Unit SSA per the existing Term::Lit { lit:
Literal::Unit } convention.
- Term::Var arm: prepended with a mut-var lookup that emits a
load <ty>, ptr <alloca> and returns the load SSA. Innermost-wins
shadowing falls out of the BTreeMap's insert-overwrites
semantics combined with the per-block save/restore.
- examples/mut_counter.ail + examples/mut_sum_floats.ail:
recursive sum_helper accumulates 1..10 (Int) or 1.0..10.0 (Float)
inside a mut block whose single var is assigned the helper's
result. Both run end-to-end printing 55.
- crates/ail/tests/e2e.rs: mut_counter_prints_55 and
mut_sum_floats_prints_55 #[test] fns using the existing
build_and_run helper.
- DESIGN.md 'What is supported' subsection: 'Local mutable state'
bullet describes the new construct, points at the two example
fixtures, and reaffirms the seal-by-construction invariant under
Decision 10.
Beyond-plan adjustments absorbed in this iter:
- synth_with_extras's parallel Term::Var arm in
ailang-codegen/src/lib.rs needed the same mut-var lookup as
lower_term's. Plan only specified lower_term's arm.
- crates/ailang-codegen/src/lambda.rs needed save/restore of all
three new Emitter fields across the lambda-body boundary plus
in-thunk splice of pending_entry_allocas at the lambda's own
entry marker, so mut-blocks inside a closure body hoist into
the closure's entry block (not the outer fn's).
