fieldtest: kernel-extension-mechanics — 6 examples, 9 findings (3 bugs, 1 friction, 1 spec_gap, 4 working)
Post-audit fieldtest for the kernel-extension-mechanics milestone. Fieldtester wrote 6 .ail consumer programs against the public interface only (design ledger + spec + ail CLI; no source crate reads), one per axis with two for the param-in pair (accept + reject). All artefacts in examples/fieldtest/ + the spec. **Working (4):** F5 NewTypeNotConstructible diagnostic is precise (names the home module + missing def in one sentence). F6 Term::New codegen-deferral diagnostic explicitly names the raw-buf milestone where support lands. F7 param-in accept-path is end-to-end (check + build + run prints 17). F8 ParamNotInRestrictedSet names type-arg + var + TypeDef. **Bugs (3, action: debug):** - F1 (axis 1) — Same-module type-scoped call `(app Type.member …)` rejected with phantom-qualified `expected <this>.T, got T`. Bare `(app member …)` from inside Type's home module works. Spec's "Canonical form decision" promises type-scoped works uniformly; the resolver appears to disagree with the workspace pre-pass on whether `<this-module>.T` equals bare `T`. Repro: examples/fieldtest/kem_2b_min_repro.ail. - F3 (axis 3) — Kernel-tier auto-import scopes the name but does not register the module as a resolvable qualifier prefix. Per the pre-pass, a bare `StubT` in a type slot is qualified to `kernel_stub.StubT`; the resolver then rejects `kernel_stub` as unknown. Asymmetric: prelude's free fns work (per prelude_free_fns.rs), but the stub's TypeDef is effectively unreachable from any consumer. Repro: examples/fieldtest/kem_3_stub_consumer.ail. - F4 (axis 3, spec/ship coherence) — The spec's prep.3 worked- consumer relies on `(new StubT 42)`, but the shipped STUB_AIL has only a TypeDef + ctor — the `(fn new ...)` the spec designed is missing from the implementation. The diagnostic the resolver does emit on the consumer (F5) is precise; the bug is the absent def itself. Resolution: re-add the `new` to STUB_AIL (the spec's design), refresh the drift pin. **Friction (1, action: plan-or-defer):** - F2 — Loader's sibling-only module resolution forces symlinks for any cross-module fixture sitting outside the canonical `examples/` directory. The kem_1 example required local symlinks for std_list.ail + std_maybe.ail. Secondary: the diagnostic message names only the .ail.json path even though .ail also resolves — actively misleading. Recommended: small tidy iter for loader workspace-search-path + diagnostic clarity. **Spec-gap (1, action: ratify):** - F9 — `design/models/0007-kernel-extensions.md:80` uses `unit` as a value literal of type Unit; the checker treats it as a Term::Var lookup and emits [unbound-var]. Either ratify `unit` as the canonical Unit-value literal in the language, or tighten the design model to use the existing idiom. The current model/ surface disagreement is a small but real LLM-author trap. **Symlinks committed** as evidence of the F2 workaround: examples/fieldtest/std_list.ail and std_maybe.ail are symlinks into ../. They are the fingerprint of the friction — removing them silently would erase the evidence. Per Iron Law, fieldtester did not work around bugs — they were all surfaced and recorded. The kem_2b_min_repro.ail fixture exists specifically because F1 surfaced mid-drafting and got minimised; kem_3_stub_consumer.ail also stays as the F3 RED-side fixture. Triage (next-step routing for /boss): F4 → small inline fix (add (fn new ...) to STUB_AIL + drift refresh) F9 → small inline ratify (whitepaper edit) F2 → backlog issue, deferred (single tidy iter someday) F1, F3 → debug skill dispatches, then implement mini-mode F5-F8 → carry-on, recorded as wins |

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 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. Stats file: `bench/orchestrator-stats/2026-05-21-iter-operator-routing-eq-ord.1.json`. closes #1 |

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 —
code is SoT), 5 design/models/*.md whitepapers, and
docs/journals/2026-05-19-design-decision-records.md (the
relitigation-guard archive — every why/rejected/does-not-do/rollback/
empirical ### moved out at ###-granularity). Clean cut: git rm
docs/DESIGN.md, no stub.
RED-first crates/ailang-core/tests/design_index_pin.rs — the 4-clause
anti-regrowth spine (DESIGN.md-gone / every-INDEX-link-resolves /
every-contract-names-a-resolvable-ratifier /
contracts-carry-no-decision-record-prose) — demonstrably RED before,
GREEN after. Build-atomic by task ordering: design_schema_drift.rs's
include_str! (the only compile-time consumer) retargeted to
design/contracts/data-model.md BEFORE the deletion; its
## Data model/## Pipeline slicer dropped (a simplification the split
enables). 2 NoInstance diagnostics + 2 lockstep E2Es retargeted to
design/contracts/{float-semantics,typeclasses}.md. ~12 agent reading
lists + 5 SKILL bodies + CLAUDE.md + skills/README.md + ~25
code/C/.ail/spec comment xrefs retargeted; OQ7 dangling 'Iter 13b'
cite deleted (no forward target — a pointer would be fiction).
honesty-rule.md rewritten so the rule names the new home
(rationale->journals), resolving the recon-found internal
contradiction; the two docs_honesty_pin.rs:70,72 pinned phrases kept
verbatim+contiguous.
Boss-verified independently: cargo test --workspace 646 passed /
0 failed; design_index_pin 4/4; acceptance grep CLEAN of live
DESIGN.md refs (residuals = only the spec-mandated clause-4
deletion-enforcer). 2 DONE_WITH_CONCERNS routed to the mandatory
milestone-close audit: (a) str-abi.md:23 '(iter str-concat,
2026-05-13)' provenance stamp trips advisory architect_sweeps Sweep-1
— Boss-confirmed byte-identical to DESIGN.md@deeffb1:2062-2065, a
faithfully-migrated PRE-EXISTING anchor (regexes verbatim, only path
retargeted), NOT split-introduced — RATIFY-or-tidy at audit; (b) a
now stale-direction intra-prose 'see Str ABI below' cross-ref in
float-semantics.md — audit-adjudication candidate. Plan defect noted:
Task 9 Step 4's verbatim acceptance grep used a ^./ anchor not
matching the system's grep -rIn output; substance re-verified CLEAN.

fieldtest: embedding-abi-m1 — 4 examples, 4 findings (0 bug, 1 friction, 2 spec_gap, 3 working)
Surface-touch fieldtest of M1's (export "<sym>") + --emit=staticlib + scalar/effect-free gate. DESIGN.md + public examples only (no compiler source). The M1 thesis is empirically substantiated: - [working] Int EMA + Float leaky-integrator both first-try clean end-to-end (author -> --emit=staticlib -> C link -> typed scalar return; s==67 / s==1.875, exit 0). Clause-1 confirmed. - [working] Both clause-3 rejections precise + self-correcting (export-non-scalar-signature on IntList param; export-has-effects on !IO). Clause-3 confirmed. - [working] (export) orthogonality + zero-export staticlib guard match spec. - [friction] form_a.md 'wrap every param in own/borrow' misdirects the headline scalar export -> body-pointing use-after-consume / consume-while-borrowed; only bare (con Int) checks. Pre-existing form_a.md defect M1 made acute (not introduced). - [spec_gap] form_a.md item 1 unconditional; scalar params take no mode (shares root with the friction). - [spec_gap] no public emit-ir --emit=staticlib though Decision 5 makes kernel-IR readability load-bearing. Boss verified independently via the public CLI (positive E2E builds both archives; both rejections fire the documented codes). 0 bugs: M1 capability + gate sound. Findings route to the roadmap as follow-up (not M1-blocking, no debug). |

fieldtest: remove-mut-var-assign — 4 examples, all working; milestone CLOSED
Post-audit downstream-LLM-author field test of the post-removal Form-A surface. 4 fresh real-world programs written from DESIGN.md + form_a.md + public examples only (no compiler source): running sum-of-squares accumulator (loop/recur → 385), grade cascade (let-threaded if → 4/2/0), Horner polynomial straight-line build-up (let-shadow chain → 73), multi-state bracket scanner threading (rest,depth,ok) by tail recursion → true/false. 0 bugs, 0 friction, 0 spec_gap, 4 working — every task clean and correct on the first try with only let/if/loop/recur; all parse|render|parse byte-identical; zero mut/var/assign tokens produced (a doc-faithful author did not reach for the removed construct). The closest-to-friction case (multi-state machine restates the full state tuple per tail-call) is correctly classified working, not a spec_gap: that explicit-dataflow cost is the local-reasoning pillar working as designed; mut's implicit cross-iteration persistence is exactly the failure class the removal eliminates. mut-keyword rejection is fail-closed with a diagnostic that enumerates the surviving forms (no tombstone, no-nostalgia, as spec'd). Removal thesis empirically CONFIRMED — mut was redundant with let/if/loop/recur in 100% of the fresh tasks. The remove-mut-var-assign milestone is fully ratified and CLOSED: spec+plan+iter, audit clean (architect [high] form_a.md fixed in .tidy, bench causally exonerated), fieldtest clean. Roadmap P0 flipped [~]→[x]; WhatsNew user-facing entry appended. |

iter remove-mut-var-assign.1: atomic removal of mut/var/assign
mut/var/assign removed from AILang entirely and atomically. Deleted: Term::Mut/Term::Assign/struct MutVar; the three Form-A keywords + parse_mut/parse_assign + grammar EBNF; the 4 mut CheckError variants; the mut_scope_stack synth threading (param dropped from synth + every internal/external/test caller); the two lower_term arms; and every exhaustive no-_ Term::Mut/Term::Assign match arm across 17 source files — cut in lockstep with DESIGN.md, fixtures, the drift trio, carve-out and roadmap so the schema is honest at every commit. 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). Independent verification: cargo test --workspace 605/0, zero residual mut symbols in any crate source, loop/recur non-regression all green (55 / 500000500000 / infinite-compiles / the lambda_capturing_loop_binder pin), roundtrip_cli PASS. One DONE_WITH_CONCERNS: a 4th recurrence of the recon-undercount class (in-source mod tests + a drift-pin fn + 5 orphaned mut .ail.json carve-outs + a non-enumerated E0599); all resolved within implementer remit, no behaviour change. Milestone-close audit then fieldtest remain. spec docs/specs/2026-05-18-remove-mut-var-assign.md (grounding PASS) plan docs/plans/remove-mut-var-assign.1.md |

fieldtest: loop-recur — 10 examples, 6 findings (milestone CLOSE, clean on all axes)
Post-audit downstream-LLM-author field test of the shipped loop/recur surface (DESIGN.md + public examples only). 3 real iterative programs (Newton isqrt, Collatz, Euclidean gcd) + 5 plausible-mistake negatives + 2 no-termination probes, all run through the public ail CLI. 0 bugs. 4 working findings on the milestone's own axes: rejection diagnostics point-exact AND self-fixing; recur tail-position threads through match/let/outer-if (spec only showed if); loop composes as a value sub-expression + byte-stable round-trip; no-termination boundary exact. This empirically substantiates the "LLM author can now write iterative programs" claim. Two orthogonal non-blocking findings, neither in loop/recur scope, both routed to P2 todos (refused the scope creep into a loop/recur tidy): niladic (app f) spec_gap independently re-confirms the existing mut-local-F3 roadmap item (the design-fork decision deliberately NOT auto-ratified under /boss — parked, priority-strengthened); module-level (doc) diagnostic-hint friction (one-line tidy). Boss-verified independently (gcd->27; recur-outside-loop fires exact). The standalone loop/recur milestone is fully ratified and CLOSED: 3 iterations + tidy shipped, audit clean (drift resolved, bench pristine carry-on), fieldtest clean on every axis. Roadmap P0 marked closed. |

fieldtest: mut-local — 6 examples (4 positive + 2 negative probes), 0 bugs / 3 friction / 1 spec_gap
Boss-dispatched fieldtest after audit-mut-local closed. Six AIL
Surface (.ail) fixtures under examples/fieldtest/ exercise the
shipped mut-local surface from a downstream-LLM-author's perspective
(no compiler-source access; DESIGN.md + public examples only).
Positive fixtures all run end-to-end first-try:
- mut-local_1_factorial.ail: straight-line Int accumulator
unroll (5!), prints 120.
- mut-local_2_classify_temp.ail: nested-if assigns into a Unit-
typed mut block, prints classification code.
- mut-local_3_horner.ail: Float mut accumulator for polynomial
evaluation, prints 18.
- mut-local_4_has_small_factor.ail: Bool mut flag via four
if-then-assign checks, prints true.
Negative probes confirm diagnostics fire as documented:
- mut-local_5_lambda_capture_probe.ail: [mut-var-captured-by-lambda].
- mut-local_6_diag_probe.ail: [mut-var-unsupported-type].
Findings:
[friction] F1 — mut without iteration: the accumulator-over-an-
iteration shape never materializes. Without while/for, the LLM-
author still writes a tail-recursive helper (the very pattern
the milestone Goal said mut would replace). examples/mut_counter.ail
illustrates the degeneration. Routing: planner for a while/for
iteration OR tighten DESIGN.md to name the gap honestly.
[friction] F2 — all four mut-related diagnostics emit their
bracketed [code] twice ('error: [code] fn-name: [code] message').
Mechanical bug: the #[error('[code] ...')] Display attributes I
authored in mut.2/mut.4-tidy include the bracketed prefix in the
message body, and the cli-diag-human formatter adds another from
CheckError::code(). Routing: debug (mechanical message-body
cleanup).
[friction] F3 — no surface form to call a zero-arg fn ('(app f)'
rejected at parse with 'expected at least one argument').
Orthogonal to mut-local but surfaced building the closure-factory
probe. Routing: planner for a small tidy iter.
[spec_gap] F4 — DESIGN.md does not name the 'use a tail-rec
helper instead' workaround for the iteration-over-accumulator
shape that mut alone cannot express. Routing: ratify in DESIGN.md
alongside F1's resolution.
[working] W1/W2/W3 — surface reachable on first read; diagnostics
pinpoint cause (mut-assign-out-of-scope even lists available
vars); composes cleanly with if + lambda-without-capture +
final-expression position.
Spec: docs/specs/2026-05-15-fieldtest-mut-local.md (333 lines).

iter rpe.1: retire per-type print effect-ops
Single iter shipping the post-milestone-24 follow-up named in
docs/specs/2026-05-14-retire-per-type-print-effects.md. After this
iter the only surviving direct-output effect-op is `io/print_str`;
all per-type print primitives are replaced by the polymorphic
`print` helper (prelude, iter 24.3).
Components:
- 92 examples/*.ail fixtures migrated (do io/print_<T> x) →
(app print x); 6 .prose.txt snapshots regenerated via `ail prose`.
- Four-site lockstep compiler deletion: crates/ailang-check/src/builtins.rs
(3 effect_ops.insert blocks + 3 list() rows + the
install_io_print_float_signature test + module + EffectOpSig
doc-comments); crates/ailang-codegen/src/lib.rs lower_app
(3 arms + lowers_io_print_float test); crates/ailang-codegen/src/synth.rs
builtin_effect_op_ret match-arm pattern. Dead `intern_string`
helper removed as a follow-up.
- Five incidental test-body migrations (ailang-check x2, ailang-core
spec_drift + design_schema_drift, ailang-surface/src/lex.rs,
ailang-prose/src/lib.rs round-trip test).
- Cat B test-harness patch: six IR-shape tests in
crates/ail/tests/e2e.rs gained a monomorphise_workspace call
before lower_workspace_with_alloc so they follow the same
pipeline as `ail build` (the home-rolled desugar+lift loop
stayed because mono's precondition is "already lifted"; mono
inserts after lift).
- Six doc-comment touch-ups (lex.rs module doc, parse.rs
diagnostic example, ail/src/main.rs x2, runtime/str.c %g anchor,
crates/ailang-core/specs/form_a.md surface-spec example).
- DESIGN.md seven-site sweep (Decision 11 example, Polymorphic
print past-tense, Heap-Str output sentence, effect-op
invocation comment, Float NaN paragraph re-anchored on
float_to_str, two "What is supported" lists).
- Three E2E test-comment polish + four IR-snapshot refresh + one
canonical-hash pin update (plan-unanticipated downstream
consequences of the corpus migration).
- bench/{check,compile_check,cross_lang}.py: all exit 0; no
ratification needed.
- Roadmap entry struck through; per-iter journal at
docs/journals/2026-05-14-iter-rpe.1.md.
Tests 564/0/3. cargo clippy and cargo doc: zero warnings.
Two upstream codegen bugs surfaced during the first BLOCKED
attempt and were fixed in separate iters before this retry:

fieldtest-form-a: 4 fixtures + spec report; agent doctrine update
Boss-dispatched fieldtest at milestone close. Agent authored 4 .ail fixtures (factorial smoke + Show user-ADT + user-class Describe with two instances + two-module workspace) from DESIGN.md + form_a.md only (no compiler-source reads, no spec-of-milestone reads). All four fixtures `ail check` ok and `ail run` produces expected stdout. Findings (1 bug, 1 friction, 2 spec_gaps, 3 working): - [bug] instance-method-body unbound-var bypasses `ail check` — forma_3 first attempt called `str_concat` inside the instance method body; `ail check` returned ok, `ail build` died with the monomorphise_workspace "unknown identifier" diagnostic. Same shape at fn-body level correctly fires `[unbound-var]` at check time. Next: debug skill, RED-first against `ail check`. - [friction] no `str_concat` primitive. Every realistic Show MyType body wants string concatenation; the absence forced the agent to shape examples around bare int_to_str / ctor-arity-1 patterns. Next: small planner tidy iter wiring `str_concat` symmetric to `str_clone` and `int_to_str`. - [spec_gap] form_a.md has zero references to class, instance, constraint, or method productions — pre-22 surface only. The form-a-default-authoring milestone made .ail the authoring form, but the form_a spec doc remains pre-typeclass. - [spec_gap] form_a.md leaves the class-qualifier ambiguity in `(instance (class X))` unspecified — bare-class-name vs canonical- form rule from mq.1 is not documented at the surface level. The agent picked the bare-name reading from the corpus; the canonical- form reading is equally plausible from the schema. Boss-side cleanup at commit time: - Deleted 8 stale .ail.json sidecars in examples/fieldtest/ (4 forma_* derived by the fieldtester per old dual-form workflow + 4 pre-existing floats_* from the prior fieldtest milestone that iter form-a.1 T8 missed because the bash deletion loop globbed only examples/*.ail.json direct children). - Updated skills/fieldtest/agents/ailang-fieldtester.md to remove the now-obsolete "generate canonical JSON sidecar" step (Phase 3 rewritten + Iron Law + Reading list + Common Rationalisations + Red Flags all aligned to the post-form-a single-form doctrine). cargo test --workspace: 557 passed, 0 failed, 3 ignored (unchanged from audit-form-a — the fieldtest fixtures are standalone, not referenced by any test). Findings deferred to follow-up iters; the milestone close itself is still clean. |

iter ext-rename: .ailx → .ail across the live toolchain
The surface-form file extension changes from .ailx to .ail. AILang's
authoring surface now uses the same .ail stem as its canonical JSON
form (.ail.json), giving the language a single coherent extension
family: .ail is the LLM-authored Form A, .ail.json is the canonical
JSON-AST Form B.
Scope (touched):
- 61 example renames examples/**/*.ailx → .ail (git mv)
- 1 rename experiments/.../rendered/ailx.md → ail.md
- 35 content-edited live-toolchain files (crates/, docs/DESIGN.md,
docs/roadmap.md, docs/PROSE_ROUNDTRIP.md, skills/, bench/reference/*.c,
experiment crates under experiments/.../{render,harness,master})
- Experiment-crate cohort rename Cohort::Ailx → Cohort::Ail,
Form::Ailx → Form::Ail, per_cohort/ailx → per_cohort/ail,
{form-only: ailx} → {form-only: ail}, ```ailx → ```ail
Out of scope (deliberately untouched, to preserve honest history):
- docs/journal-archive.md (content-frozen per CLAUDE.md)
- docs/journals/, docs/specs/, docs/plans/, bench/orchestrator-stats/
- experiments/.../runs/ (frozen LLM-output artefacts; models actually
saw .ailx — renaming would falsify the experimental record)
Verification: cargo build/test --workspace green; experiment crate
cargo test green; bench/check.py + compile_check.py + cross_lang.py
all 0-regressed; negative grep for ailx|Ailx|AILX outside the
out-of-scope paths returns zero matches.
Opens immediate follow-up: roadmap.md P2 todo `ail check`/build/run
accept .ail extension — after this rename, .ail is canonical
authoring surface but the CLI still produces a misleading JSON-parse
error on `ail check foo.ail`. That's the next iter.
