Catches the "forgot the `main>_;` wrapper" misparse that k-means and linear-regression personas hit when chaining imperative bindings at the top level. Without the wrapper the parser used to either die on the bare `=` (a bare `ILO-P003`) or, when a prior `name>type;body` decl was in scope, slurp the whole chain into that fn's body and emit a wall of misleading `ILO-T005` cascades anchored on the wrong line. `ILO-P102` collapses both shapes into a single diagnostic that names the offending binding and suggests the `main>_;` wrapper. Parser-only change; identical output across VM and JIT. -### Fixed + +### Fixed (from main) - New `ILO-W002` warning when the foreach collection is a direct `jpar!` or `jpar!!` call. Surfaces the hint pointing at `jpar-list!`, which asserts the top-level JSON is an array and returns `R (L _) t` so the unwrap composes cleanly into `@`. Catches the `mempool-fee-estimator` failure mode where the polymorphic `jpar` Ok type forced the wrapping function's return type to `R t t` and threaded `?` through downstream code. The `@x (jpar-list! body){...}` form continues to type-check silently; `xs = jpar! body; @x xs{...}` (the explicit-bind form) is unchanged. Diagnostic-only; no behaviour change in the runtime engines. Closes pending.md item #5f. - Cascading `ILO-T005 undefined function 'X'` errors from a single parse failure now collapse to one diagnostic per parse-failed function with a cross-reference back to the originating parse error. Previously, ONE broken function body produced N undefined-function errors (one per call site), burying the root cause; the cron-explainer persona logged 286 ILO-T005, 107 ILO-P009, and 47 ILO-P001 from roughly 10 root causes in a single run. The parser now records function names whose return-type or body failed to parse on `Program.parse_failed_fns`, and the verifier (1) skips type-checking those functions' bodies (their AST is poison) and (2) emits one collapsed `ILO-T005` per parse-failed name with a hint pointing at the root parse error code. Real undefined-function errors (typos, missing imports) still surface normally with the usual suggestion text. -### Changed +### Changed (from main) - `find_libilo_a` (AOT linker helper in `src/vm/compile_cranelift.rs`) now honours `CARGO_TARGET_DIR` and `.cargo/config.toml`'s `build.target-dir` before falling back to `$CARGO_MANIFEST_DIR/target`. Fix worktrees that redirect cargo's target dir out of the tree (e.g. `[build] target-dir = "/tmp/ilo-targets/..."`) no longer need a `ln -sf .../release/libilo.a target/release/libilo.a` workaround for the AOT tests to find the staticlib. Test-infrastructure only; no user-visible change to `ilo compile`. - Versioning scheme: semver → CalVer. Releases are `YY.M` (e.g. `26.5`), patches `YY.M.P` (e.g. `26.5.1`). The version string carries recency so an agent loading `ilo spec --json ai` knows which spec applies without a changelog lookup. Last semver release is `0.12.1`; first CalVer release cuts on the next breaking change as `26.X`. Hard cut, no `0.13` bridge. Branching model splits: `main` carries stable + RC tags (`26.5`, `26.5.1`, `26.5.2-rc.1`), `next` carries dev tags only (`26.6-dev.N`).

Errors as `ILO-R009` on dim mismatch, empty matrix, or ragged rows. Tree-bridge eligible -- VM and Cranelift inherit through the bridge without new opcodes. Closes pending.md #5an. - `lstsq xm ys > L n` builtin. Ordinary least squares via the normal equations: returns the coefficient vector `b` minimising `||xm·b - ys||²`. Closed-form OLS as a thin wrapper around `solve (Xᵀ X) (Xᵀ y)` - collapses the 5-line recipe (`transpose` + `matmul` + `matmul` + `solve` + index-fiddling) into a single call, saving ~30 tokens per OLS use. Errors as ILO-R009 on rank-deficient design, underdetermined system (cols > rows), row/length mismatch, or empty input. Same precision tier as `solve`/`inv`/`det` (LU with partial pivoting); numerically inferior to QR/SVD for ill-conditioned designs. Tree-bridge eligible - VM and Cranelift inherit through the bridge with no new opcodes. Motivated by the linear-regression persona. - `OP_TAILCALL` opcode and VM-compiler emission. When a static user-fn call sits in tail position (the function's last statement, or the last statement of any context that itself sits in tail position), the bytecode VM compiler now emits `OP_TAILCALL` instead of `OP_CALL` + `OP_RET`. At runtime the VM reuses the current `CallFrame` rather than pushing a new one, so a function that recurses only in tail position runs in O(1) frame memory: `count-down 5_000_000` now completes in tens of milliseconds on `--vm`, mirroring the tree-interpreter trampoline shipped in the previous PR. Cross-function tail chains (`f` tail-calls `g` tail-calls `h`) work too -- the chunk index is swapped in place. Auto-unwrap (`!` / `!!`) calls stay on the normal `OP_CALL` path because the post-call result probe wants to inspect the value before deciding whether to propagate. The Cranelift JIT/AOT path lowers `OP_TAILCALL` identically to `OP_CALL` for now (semantically correct, no host-stack TCO benefit); native `return_call` lowering ships in a follow-up PR. @@ -44,7 +276,7 @@ ### Renamed -- `--run-vm` renamed to `--vm`, symmetric in shape with `--jit` and `--run-llvm` (where the flag names the engine, not the action). `--run-vm` is retained as a hidden alias for one release; every invocation emits a one-shot stderr hint `hint: --run-vm → --vm (canonical form).

This branch is additive on the lexer / parser; deletions are limited to skill docs. +- Produce a clean A/B against `main` with the same personas, same models, same prompts, same task set. The only variable is the surface spec the agent sees. +- Decide.

If retry cost doesn't drop, or drops by less than the generation overhead, we lose. + +--- + +## 2. Surface changes + +Each subsection is a concrete syntactic decision with examples, the rationale, and the persona-log evidence motivating it. + +### 2.1 Infix as canonical for arithmetic, comparison, and logical operators + +**Current SPEC.md:** prefix is canonical, infix is "available for readability when needed". Skill docs lead with prefix. + +**Agent-natural mode:** infix is canonical for arithmetic (`+ - * /`), comparison (`= != > < >= <=`), and logical (`& |`). Prefix forms remain fully accepted. Skill docs lead with infix. + +``` +-- canonical (was: prefix preferred) +total = a + b * c +ok = x >= 0 & x <= 100 +``` + +**Justification.** The manifesto's prefix argument is real and measured: across 25 expression patterns, prefix saves 22% tokens vs infix. But the persona logs show the friction is asymmetric: infix is **the agent's first try every time**, and the resulting retries dominate. Specific shapes that recur in the logs: + +- `+ -*a b *c d` → ILO-P021 double-minus trap, with a hint pointing back to a prefix form the agent then has to re-derive. +- `*/a b c` parsed as `(a/b)*c` instead of `(a*b)/c` - silent arithmetic gotcha; bit a forensics persona and an RK4 persona. +- `++++r1 r2 r3 r4` silent-EOF on 4-deep prefix chains. +- `+ - +x y z` - prefix-chain ergonomics that compile but read backwards. + +The 22% generation saving is real, but in practice ~25% of prefix programs in the persona corpus hit a parse re-roll or a silent-miscompile that costs more than 22% to recover from. + +**v0 decision:** infix-canonical in skill docs and examples. Prefix continues to parse and continues to be the cheaper form for an agent that has been **trained on it**. We are testing whether *current* untrained models do better with infix because their training prior is so strong. + +### 2.2 One conditional, with a Result-match carve-out + +**Current SPEC.md:** ilo today has *three* conditional shapes plus several variations: + +- `cond{body}` - braced conditional, **no early return** +- `cond a b` braceless guard - **early return** when condition is comparison/logical +- `?cond{a}{b}` - ternary, value-producing +- `?=cond a b` / `?>cond a b` / `? `=mhas m k` inside `@` loop body triggers braceless-guard parse - `=mhas m k true{body}` was read as guard-condition `=mhas m k` with body `true` then unexpected `{body}`. + +> `=cond{val}` reads like "if cond, return val" but it isn't. Required a dedicated footgun note in SPEC.md. + +> bool match arms `?bk{"x"}{"y"}` parse incorrectly; required braced-conditional or helper-function workaround. + +**Agent-natural mode:** + +- **Primary conditional in skill docs:** `if cond { a } else { b }`. Value-producing. No early return (matches the current ternary semantics). `else` is optional; absent `else` produces `nil`. + + ``` + v = if x >= 0 { x } else { -x } + if found { log "hit" } + ``` + +- **Early return** is `if cond { ret a }` or the existing braceless guard `>=x 0 ret x`. Skill docs lead with the `if`-with-`ret` form (one shape, predictable, no spec-section-on-when-braces-trigger-early-return). + +- **Result match keeps `?r{~v:body;^e:body}`**. This isn't a conditional, it's pattern-destructure on a tagged union. The persona logs show **no friction with the Result-match shape itself** - friction is with the body restriction (single-expression), which is fixed separately in 2.3. We retain it because it does a different job from `if`. + +- **General match keeps `?subj{pat:body;pat:body;_:body}`**. Same reason: destructuring closed sums and numeric/text dispatch is a distinct operation from boolean branching. + +- **`cond{body}` braceless-cond and `?h`/`?=`/`?>`/`?<` prefix-ternary stay parsing**. They are dropped from the skill docs and from the SKILL.md examples. Programs that use them still run. We deliberately stop teaching them. + +**Why not just keep `?h cond a b`?** It is denser. But the persona evidence is that agents who don't already know it write `?cond{a}{b}` first, hit the bool-vs-comparison disambiguator, and retry. The `if/else` form is recognised by every model's training prior on the first token. The generation cost goes up ~6 tokens per branch; the retry cost goes down to zero on this construct. + +**The parser already gives a hint for `if` today** (`reserved_keyword_message`). Under this branch the hint is removed for `if`/`else` and the keywords parse for real. + +### 2.3 Match arm bodies accept block statements + +**Current SPEC.md:** match arm body is a single expression. Multi-statement bodies require pulling the body out into a named helper function. + +This is logged across at least 5 personas: + +> Match arm bodies cannot contain multiple statements. `~v:{stmt1;stmt2}` and `~v:stmt1;stmt2` both fail - the arm body is a single expression only. This forced the pattern of wrapping all complex logic in named helper functions, which then ran into the non-last-function safe-ending constraint. Required significant restructuring across every query. + +> `rdl!` requires enclosing function to return `R`, but the `~v:...` match arm syntax cannot have block bodies - so the two patterns conflict. + +> Inline lambdas to `grp`/`map`/`flt` with multi-statement bodies don't work: `grp(v>t;v)` fails with `ILO-P003`. + +**Agent-natural mode:** match arms accept `pat: { stmt; stmt; expr }`. The brace-wrapped form is a block whose value is its last expression (same semantics as braced bodies elsewhere). Single-expression arms continue to work unchanged. + +``` +?r { + ~rows: { n = len rows; total = sum rows; total / n } + ^e: log e +} +``` + +Bare single-expression arms parse exactly as today; the only addition is that the arm body alternatively accepts `{` ... `}`. + +**Token cost.** +2 tokens per block arm. Personas were currently paying +1 helper function declaration (~10-20 tokens) plus extra plumbing per multi-statement arm; this is a clear net win. + +### 2.4 Loops: `for`/`while` accepted alongside `@`/`wh` + +**Current SPEC.md:** `@x xs{body}` for foreach, `@i a..b{body}` for range, `wh cond{body}` for while. + +Persona log evidence is softer here than for conditionals - personas mostly learn `@` and `wh` quickly. But the hesitation-then-retry cost is real, particularly on the first generation. ILO-P003 surfaces with a hint pointing back to `@x xs{body}`. + +**Agent-natural mode:** accept the following as aliases. Skill docs lead with the long form. + +``` +for x in xs { ... } -- aliases @x xs{...} +for i in 0..n { ... } -- aliases @i 0..n{...} +while cond { ... } -- aliases wh cond{...} +``` + +`@` and `wh` keep parsing. The choice of leading shape in the skill docs is the `for`/`while` long form: it matches the agent's training prior, the per-program token cost is small (~2 tokens per loop), and removing the "which symbol was the loop keyword again" lookup cost is what we're paying for. + +This is the most genuinely manifesto-tense change in v0. See section 6 for the falsification criterion. + +### 2.5 Function declaration: unchanged + +`f x:n>n;body` stays. The signature line is the densest part of the language and zero personas have logged friction with it. + +We deliberately do **not** add `fn f(x: n) -> n { body }` even though it matches the agent prior. The token cost is too high (+8 to +12 per declaration, multiplied by every helper a persona writes) and the friction signal isn't there in the logs. + +### 2.6 Nil-coalesce: keep infix, lead with infix in docs + +`??` is currently spec'd as infix-only at expression position; the `??x default` prefix form errors with ILO-P009 at statement-start. This is logged by 7+ personas and is by far the most-recurring single complaint. + +**Agent-natural mode:** no syntactic change. `??` remains infix-only. But skill docs lead with the infix shape (`v??0`) explicitly and add an inline gotcha line ("`??` is infix-only - never start a statement with `??`"). This is doc-only and free, but it belongs in the surface spec because the friction is surface-level. + +Note: a parallel fix-track on `main` is welcome to either add a prefix `??` form or fold a friendlier error. That's not this experiment's job. + +--- + +## 3. What we are not touching + +Listing explicitly to keep scope honest: + +- **Builtin names and signatures.** `map fn xs`, `flt fn xs`, `fld fn xs init`, `srt xs`, `cat xs sep`, `spl s d`, `len xs`, `hd xs`, `tl xs`, all builtin aliases - unchanged. No method-call sugar. +- **Prefix-Polish call shape generally.** Calls are `map fn xs`, not `xs.map(fn)`. +- **Record/list literals.** `[a, b, c]`, `point x:1 y:2`. Unchanged. +- **`>` return-type marker.** Stays in function declarations. +- **Reserved words for binding/function-name positions.** `if`, `for`, `while`, `else` become control-flow keywords in this branch and are still rejected as identifier names. The list grows by 4.

An agent trained on the canonical-prefix corpus and an agent trained on the agent-natural corpus will write subtly different programs. Spec confusion compounds: which is the "real" ilo? + +**Mitigation.** v0 is explicitly an A/B branch. If it wins, `next` adopts the new surface as canonical and the canonical-prefix forms degrade to legacy / accepted-but-not-taught. There is exactly one canonical surface at any time. The branch does not get to coexist long-term with `main`'s canonical. + +### 6.2 Per-program token-cost overhead + +**Risk.** Every `if/else`, every `for ... in`, every `while`, every block-bodied match arm spends more tokens than the form it replaces. A persona that writes 20 conditionals and 5 loops pays ~80-100 extra generation tokens. + +**Mitigation.** The hypothesis *is* that retry cost dominates. If it doesn't, this risk fires and we kill the branch. See 6.5. + +### 6.3 Manifesto coherence + +**Risk.** The manifesto says: "If a feature reduces total tokens, it's in. If it increases it, it's out. No exceptions for elegance, readability, or convention." The agent-natural surface is, on its face, a concession to "convention." + +**Mitigation.** It is a concession to **agent priors**, not human convention. The manifesto's metric is total tokens including retries. The retry-loop cost is the operative variable. Until models are trained on ilo, the spec-loading + retry-loop terms dominate, and reducing those at the cost of a generation-loop tax is consistent with the principle. The manifesto's principle 1 explicitly says: *"spec clarity is itself a token cost - a confusing spec means more retries."* This experiment tests whether the same logic applies to surface familiarity. + +If the data says no, the experiment loses and the manifesto wins. That's the point of running it. + +### 6.4 Silent miscompiles from the additive accepts + +**Risk.** Adding `if` / `for` / `while` as new keywords could mis-parse existing programs whose identifiers shadow them. Adding block bodies to match arms could change parse precedence in unexpected ways. + +**Mitigation.** `if`, `for`, `while`, `else` are already reserved words in the existing parser (binding-position rejection with ILO-P011-class hints). Programs on `main` cannot bind them today, so no existing program can collide. Match-arm block bodies are gated by an opening `{` immediately after the arm's `:`, which is currently a parse error - no existing program reaches that path. + +### 6.5 Falsification criterion + +The experiment is killed if **any of**: + +- **Total mean tokens per persona increases** vs baseline by >5%. +- **% of personas with outcome=working** stays flat or decreases. +- **Net friction items logged** does not decrease. + +The experiment is **adopted into `next`** if **all of**: + +- Total mean tokens per persona decreases vs baseline by >10%. +- % outcome=working increases. +- Net friction items logged decreases. + +The experiment is **partial** if results fall between.

Personas may hit this and reach for unwraps. +- Is `for i in 0..n` parser ambiguity worse than `@i 0..n`? Both share a range syntax; the keyword change is purely the lead-in token. +- Should the skill docs keep one boxed example of the prefix form, labelled "token-tight alternative", for the agents that have learned prefix and want to use it? Or does the dual presentation itself cost tokens at spec-loading time?

It supports every opcode (closures with Phase 2 capture, listview windows, fused len-of-filter, every modern shape), and avoids the JIT compile-and-bail cost paid by the pre-v0.11.9 Cranelift-first default whenever a program touched an opcode the JIT couldn't handle. Cranelift JIT is opt-in via `--jit`; on opt-in, the JIT runs hot numeric loops and falls back to the VM on bailout. Phase 2 captures run natively on every public backend - VM, JIT, and AOT (`ilo compile`); AOT embeds the postcard `CompiledProgram` blob into the binary's `.rodata` so dispatch helpers can re-enter the VM on user-fn callbacks the same way the in-process runners do.

Keys are typed: text (`t`) or integer (`n`). `Int(1)` and `Text("1")` are distinct keys. mmap -- empty map mset m k v -- return new map with key k set to v mget m k -- value at key k, or nil mget-or m k default -- value at key k, or default if missing (never nil) mhas m k -- b: true if key exists mkeys m -- L t: sorted list of keys mvals m -- L v: values sorted by key mpairs m -- L (L _): sorted [k, v] pairs; mpairs m == zip (mkeys m) (mvals m) mdel m k -- return new map with key k removed len m -- number of entries Numeric keys work directly - no `str` conversion needed. Float keys floor to `i64` at the builtin boundary (matching `at xs i`); NaN/Infinity raise at runtime. idx=mmap idx=mset idx 7 "seven" -- M n t, integer key mget idx 7 -- "seven" mhas idx 7 -- true mhas idx "7" -- false (Int and Text are distinct) `jdmp` stringifies numeric keys for JSON output (JSON object keys are always strings). The round-trip via `jpar` is lossy - numeric keys come back as text. Example: scores>M t n m=mmap m=mset m "alice" 99 m=mset m "bob" 87 mget m "alice" -- 99 [Type variables] A single lowercase letter (other than `n`, `t`, `b`) in type position is a type variable, treated as `unknown` during verification. Used for higher-order function signatures: identity x:a>a;x apply f:F a a x:a>a;f x Type variables provide weak generics - the verifier accepts any type for `a` without consistency checking across call sites. [Inline lambdas] Pass a function literal directly to a HOF instead of defining a one-off top-level helper: by-dist xs:L n>L n;srt (x:n>n;abs x) xs nonempty ws:L t>L t;flt (s:t>b;>(len s) 0) ws sumsq xs:L n>n;fld (a:n x:n>n;+a *x x) xs 0 Syntax: `(: ...>;)`. Same shape as a top-level function declaration, wrapped in parens, no name. **Phase 1 (no captures)** lifts the literal to a synthetic top-level decl and works across every engine (tree, VM, Cranelift JIT, AOT). The body's free variables must all be params, locals defined inside the lambda body, or known top-level fns. **Phase 2 (closure capture)** lets the body reference variables from the enclosing scope: f xs:L n thr:n>L n;flt (x:n>b;>x thr) xs -- captures `thr` Phase 2 captures run natively on every engine: the tree interpreter, the register VM, the Cranelift JIT, and the Cranelift AOT backend. Each free variable is snapshot by value at the call site (`Expr::MakeClosure`) and appended to the call frame's arg slice on dispatch. The AOT backend additionally embeds the postcard-serialised `CompiledProgram` into the binary's `.rodata` and publishes TLS pointers on startup, so dispatch helpers can re-enter the VM on user-fn callbacks. The ctx-arg form (`srt fn ctx xs`) remains the cross-engine alternative when you want explicit state without forming a closure. -NAMING: Short names everywhere. 1–3 chars. `order`=`ord`=truncate `customers`=`cs`=consonants `data`=`d`=single letter `level`=`lv`=drop vowels `discount`=`dc`=initials `final`=`fin`=first 3 `items`=`its`=first 3 Function names follow the same rules. Field names in constructors and external tool names keep their full form - they define the public interface. [Identifier syntax] Identifiers are lowercase ASCII only, optionally with hyphenated segments. Formally: `[a-z][a-z0-9]*(-[a-z0-9]+)*`. Capital letters and underscores are rejected at the binding and call site. run -- OK run-d -- OK (hyphen separates segments) r2 -- OK (digit after first letter) runD -- ERROR (capital letter) RunD -- ERROR (leading capital) run_d -- ERROR (underscore not allowed in bindings) -run -- ERROR (must start with a letter) `runD` in the interactive CLI surfaces as `ILO-L003 unexpected token` with a suggestion to use `run-d` or `rund`. The constraint is intentional: a single lexical shape per identifier keeps the token stream predictable for agents and avoids style debates over camelCase vs snake_case vs kebab-case. The only place capital letters and underscores are accepted is **after `.` or `.?`** at field-access position, so heterogeneous JSON keys from real APIs work without rewriting. See [Field names at dot-access](#field-names-at-dot-access) for the full list of post-dot relaxations (`r.URL`, `r.AccessKey`, `r.user_name`, etc.). Binding names (`AccessKey = ...`) and function names (`AccessKey x:n>n;...`) still error. [Reserved words] The following identifiers are reserved and cannot be used as names: `if`, `return`, `let`, `fn`, `def`, `var`, `const`. Using them produces a friendly error with the ilo equivalent: -- ERROR: `if` is a reserved word. Use: ?cond{true:...;false:...} -- ERROR: `return` is a reserved word. Last expression is the return value. -- ERROR: `let` is a reserved word. Use: name = expr -- ERROR: `fn`/`def` is a reserved word. Use: name param:type > rettype; body These checks fire at parse time across every context the keyword can appear in: top-level declaration head (`fn>n;...`), binding LHS (`fn=5`), and **parameter position** (`g fn:n>n;fn` rejects with ILO-P011 against the param name, not a cryptic ILO-P003 against the missing `>`). Builtin names (`flat`, `frq`, `map`, `flt`, `cat`, `len`, `srt`, `hd`, `tl`, `ord`, `fld`, `lst`, ...) are also rejected as user-function names and as local-binding LHS. Without this, calls to the user fn or use sites of the local binding silently mis-dispatch to the builtin and surface as a confusing `ILO-T006` arity mismatch. The parser intercepts at the declaration site with ILO-P011 and a rename hint: flat n:n>n;n -- ERROR ILO-P011: `flat` is a builtin and cannot be used as a function name -- hint: rename to something like `myflat` or `flatof`. main>n;flat=cat xs " ";spl flat ". " -- ERROR ILO-P011: `flat` is a builtin and cannot be used as a binding name -- hint: rename to something like `myflat` or `flatv`. [Reserved namespaces] Short builtin names are precious surface and ilo reserves a stable subset of them. To save agents (and their carry-forward scripts) from "what got reserved this release?" debugging cycles, the language publishes the full short-name reserve list plus a forward-compatibility rule for future builtins. **Currently reserved short names (1-3 characters).** Every name in this list is a builtin today and triggers `ILO-P011` if used as a binding or user-function name: 1-char e 2-char at hd pi tl rd wr ct 3-char abs avg cap cat cel chr cos del det dot env ewm exp fft fld flr flt fmt frq get grp has hed inv len log lsd lst lwr map max min mod now num opt ord pat pow pst put rdb rdl rep rev rgx rng rnd rou run sin slc spl srt str sum tan tau trm unq upr wra wrl zip All builtin aliases (`head`, `length`, `filter`, `concat`, `tail`, `sort`, `reverse`, `flatten`, `contains`, `group`, `average`, `print`, `trim`, `split`, `format`, `regex`, `read`, `readlines`, `readbuf`, `write`, `writelines`, `lset`, `floor`, `ceil`, `round`, `rand`, `random`, `rng`, `string`, `number`, `slice`, `unique`, `fold`) are reserved with the same shadow-prevention semantics as canonical builtin names. Binding an alias name or using it as a user-function name fires `ILO-P011` at parse time with the canonical form in the diagnostic, since the call-site rewrite to the canonical builtin silently bypasses any user binding of the same name. Previously only `rng` and `rand` had individual guards; as of 0.12.1 every alias in the table above is covered by a single `resolve_alias` check, so new aliases automatically inherit the protection when added to the table. Longer builtin names (`acos`, `asin`, `atan`, `flat`, `take`, `drop`, `mget`, `mset`, `mmap`, `prnt`, `mapr`, `solve`, `lstsq`, `clamp`, `cumsum`, `cprod`, `median`, `matmul`, `range`, `window`, `chunks`, `walk`, `glob`, `prod`, `fsize`, `mtime`, `isfile`, `isdir`, …) are also reserved and rejected by `ILO-P011`, but the short-name namespace above is where carry-forward scripts most often collide, so it gets explicit enumeration. Longer builtin names (`acos`, `asin`, `atan`, `flat`, `take`, `drop`, `mget`, `mset`, `mmap`, `prnt`, `mapr`, `solve`, `clamp`, `cumsum`, `cprod`, `median`, `matmul`, `range`, `window`, `chunks`, `walk`, `glob`, `prod`, `fsize`, `mtime`, `isfile`, `isdir`, `ones`, `linspace`, …) are also reserved and rejected by `ILO-P011`, but the short-name namespace above is where carry-forward scripts most often collide, so it gets explicit enumeration. **Forward-compatibility rule.** Future ilo releases add new builtins under names **4 characters or longer**. A 2-character name that is not on this list today is safe to use as a binding or function name and stays safe across releases. A 3-character name that is not on this list is _highly likely_ to stay safe but is not a hard promise - the 3-char surface is already dense, and a rare ergonomic win may justify an addition, called out in the changelog. This gives agents a deterministic safe-name strategy: **2 chars**: any unreserved 2-char name is permanently fine for bindings (`ce` for "category", `ix` for index, `mn` for "mean", `pq` for "priority queue", …). Names on the reserved list above never get removed. **3 chars**: prefer unreserved 3-char names where possible. If a future release reserves one, the migration is a 1-character rename plus a changelog entry. **4+ chars**: always safe. New builtins land here first; any short alias is added later only if the long name is unambiguous and the short doesn't shadow a plausible user binding. When a collision does happen, `ILO-P011` surfaces it at the binding site with a rename suggestion - never silently mis-dispatches at the call site (see the `flat=cat xs " "` example above). Combined with the reserve list, that turns every name-collision incident into a single-character rename instead of a debugging spiral. [Cross-language gotchas] Common shapes reached for from other languages. The parser and lexer surface each with a friendly hint: `AND a b`, `OR a b`, `NOT a`=`&a b`, `|a b`, `!a`=`ILO-L001` `=a b`=`<=a b`, `>=a b` (single token)=`ILO-P003` `f=fn x:n>n;+x 1` (lambda)=`(x:n>n;+x 1)` (parenthesised lambda)=`ILO-P009` `\x{+x 1}` (Haskell/Rust lambda)=`(x:n>n;+x 1)` (parenthesised lambda)=`ILO-L001` `main:>n;body`=`main>n;body` (no `:` before `>`)=`ILO-P003` Multi-line body without braces=`@k xs{body}`, `cond{body}` on one line=`ILO-P003` `cond{^"err"}` braced-cond=Braceless `cond ^"err"` for early return=hint only `- -*a b *c d` (double-minus)=`- 0 +*a b *c d` (negate the sum)=`ILO-P021` `[k fmt2 v 2]` (call in list)=`[k (fmt2 v 2)]` or bind-first=`ILO-P101` `pts=gen-pts;cs0=[...];prnt cs0` at top level=`main>_;pts=gen-pts;cs0=[...];prnt cs0` (wrap in `main>_;`)=`ILO-P102` `((((...((1+1))))...))` 1000 deep=bind intermediates, or pass `--max-ast-depth N`=`ILO-P103` `dx=xj 0-xi` (call vs binop)=`-xj xi` or pre-bind: `nxi=0-xi;+xj nxi`=`ILO-T005` `tup.0` / `pair.0` (tuple access)=bind from `zip`-pair, then `at pair 0` (no tuple type)=`ILO-T004` Each case fires a hint pointing at the canonical form; the agent's first retry should be the right one. Identifier-shaped collisions with builtin names (`len=...`, `sin=...`) are rejected with `ILO-P011` plus a rename suggestion. The list-literal call trap (`ILO-P101`) catches the case where a variadic builtin (`fmt`, `fmt2`) appears bare inside `[...]`. Fixed-arity builtins (`str`, `at`, `map`, ...) auto-expand to a call as one element, but variadic ones can't (the parser doesn't know where their args end), so the bare form would silently fall through as multiple elements with the builtin name as an undefined Ref. Fix by wrapping the call in parens (`[k (fmt2 v 2)]`) or binding first. The top-level chain trap (`ILO-P102`) catches a bare `name=expr` at the top level. ilo requires every binding to live inside a function body; a top-level `pts=gen-pts;cs0=[[...]]; ...; prnt cs2` without a `main>_;` (or any) header used to either die on the `=` (a bare `ILO-P003`) or get slurped into a previous function's body and emit a wall of misleading `ILO-T005` cascades on the wrong line. `ILO-P102` collapses both shapes into a single diagnostic that names the offending binding and suggests the canonical `main>_;` wrapper. The double-minus trap (`ILO-P021`) catches the silent-miscompile shape `- - a b c d` for `` in `{+,*,/}`. Read intuitively as `-(a*b) - (c*d)` but parses as `-((a*b) - (c*d)) = -(a*b) + (c*d)` because the inner `-` greedily consumes both prefix-binop groups as binary subtract and the outer `-` falls back to unary negate. Fix by negating the sum (`- 0 +*a b *c d`) or binding first (`p=*a b;q=*c d;- 0 +p q`). Single-atom variants like `- -a b` remain accepted since they're unambiguous. The call-vs-binop trap (`ILO-T005` with tailored hint) catches the assignment-RHS shape `name expr` where `name` is a bound non-fn value (typically a parameter). Whitespace-juxtaposition is the call syntax in ilo, so `dx=xj 0-xi` parses as `dx=(xj 0)-xi` — a call to `xj` with argument `0`. Verification fails because `xj` isn't a function. The hint surfaces the prefix-operator alternatives (`-xj xi`, `+xj `) and the pre-bind workaround. The misparse is most common when an agent reaches for infix arithmetic between a parameter and a subexpression; pre-binding the operand always resolves the ambiguity. `ilo --explain ILO-T005` includes the full gotcha walkthrough. The tuple-access trap (`ILO-T004` with the `at ` hint) catches `tup.0` / `pair.0` shapes where `tup` / `pair` was never bound. ilo has no tuple type. `zip xs ys` returns `L (L n)` — a list of two-element lists — so destructuring a pair is `at pair 0` / `at pair 1`, not `pair.0` / `pair.1`. The hint names the exact `at` call to write. (`pair.0` itself is still valid sugar for list indexing once `pair` is bound to an `L T`; the diagnostic only fires when the identifier is unbound.) The AST depth cap (`ILO-P103`) catches deeply nested source that would otherwise blow the parser stack. Any context that compiles untrusted text - `ilo serv`, the bare-positional dispatch, the `--ast` dump - is exposed to a payload of the shape `((((...((1+1))))...))` 1000 levels deep that recurses straight through the OS thread stack. The default cap of 256 is far above anything hand-written (the in-tree examples top out under 20) and low enough to keep the worst-case stack frame in `parse_atom`/`parse_expr` inside the default 8 MB main-thread stack. Override with `--max-ast-depth N` on `ilo`, `ilo run`, `ilo check`, `ilo build`, and `ilo serv` when a legitimate program needs deeper nesting. +NAMING: Short names everywhere. 1–3 chars. `order`=`ord`=truncate `customers`=`cs`=consonants `data`=`d`=single letter `level`=`lv`=drop vowels `discount`=`dc`=initials `final`=`fin`=first 3 `items`=`its`=first 3 Function names follow the same rules.

COMMENTS: -- full line comment +a b -- end of line comment -- no multi-line comments; use consecutive -- lines -- like this Single-line only. `--` to end of line. No multi-line comment syntax - newlines are a human display concern, not a language concern. An entire ilo program can be one line. Use consecutive `--` lines when humans need multi-line comments. Stripped at the lexer level before parsing - comments produce no AST nodes and cost zero runtime tokens. Generating `--` costs 1 LLM token, so comments are essentially free. **Gotcha:** `--x 1` is a comment, not "negate (x minus 1)". The lexer matches `--` greedily as a comment and eats the rest of the line. To negate a subtraction, use a space or bind first: -- DON'T: --x 1 (comment, not negate-subtract) -- DO: - -x 1 (space separates the two minus operators) -- DO: r=-x 1;-r (bind first) OPERATORS: Both prefix and infix notation are supported. **Prefix is preferred** - it is the token-optimal form that eliminates parentheses and produces denser code. Infix is available for readability when needed.

It returns a new list with `v` appended and does **not** mutate `xs` in the caller's scope. It works in every position a value-producing expression works: -- 1. Rebind (canonical accumulator pattern) xs=[];@i 0..3{xs=+=xs i};xs -- [0, 1, 2] -- 2. Non-rebind assignment (xs preserved) xs=[1, 2, 3];ys=+=xs 99 -- xs is still [1, 2, 3]; ys is [1, 2, 3, 99] -- 3. Pipeline / argument position len +=xs 99 -- length of [xs..., 99] sum +=xs 99 -- sum of [xs..., 99] The rebind shape `xs = +=xs v` is the standard foreach-build accumulator. When the binding is RC=1 the engines mutate the underlying buffer in place (amortised O(1) per push) - but this is a behind-the-scenes optimisation. To any observer the operation is still functional: nothing outside the rebind sees the old `xs`. The non-rebind shape `ys = +=xs v` always allocates a fresh list and leaves `xs` untouched, so source aliases are safe. There is no separate `push` builtin. `+=` covers every use case and is shorter; adding an alias would mean two ways to spell the same operation, costing reasoning tokens and surface area. [Unary] `-x`=negate=`n` `!x`=logical NOT=any (truthy) [Special infix] `a??b`=nil-coalesce (if a is nil, return b)=any `a>>f`=pipe (desugar to `f(a)`)=any **`??` precedence.** Infix `??` is parsed by `maybe_nil_coalesce` after the primary expression — it binds **looser than every arithmetic, comparison, and boolean operator**, and tighter than `>>` (pipe). So `c??0+1` is `c ?? (0+1)`, not `(c??0) + 1`. Prefix `??x default` mirrors the infix form: the default slot is a full expression, exactly like the right operand of any other prefix binop. This means **`??` inside a prefix-binop chain follows the standard prefix-binop rule**: the outer op consumes its left atom, and `??` then binds the next atom as its value and the rest as its default. To get `(a ?? d) + b` you must bind first or wrap in parens: +a ??d b -- = a + (d ?? b) ← parses as prefix `??d b` +(a??d) b -- = (a ?? d) + b ← parens force the grouping x=a??d;+x b -- = (a ?? d) + b ← bind-first, manifesto-preferred The same shape applies to every prefix binop (`-a ??d b`, `*x ??y z`, `>p ??d r`, etc.). The grouping is consistent with `+a *b c` = `a + (b*c)` — a prefix op in the right-operand slot consumes its own operands greedily. The trap is that `??` reads visually like it should be sticky to the preceding atom; it isn't. When the LHS of `??` is the value being defaulted, bind first or wrap in parens. The analogous shape with the boolean operators (`+a |0 b`, `*a &1 b`) parses the same way, but those produce a type error at verify time (`+` / `*` on a bool result), so they fail loudly rather than silently miscompiling. The `??` shape is the dangerous one: both sides of `??` can be `n`, so the parse silently produces the wrong arithmetic. [Prefix nesting (no parens needed)] +*a b c -- (a * b) + c *a +b c -- a * (b + c) >=+x y 100 -- (x + y) >= 100 -*a b *c d -- (a * b) - (c * d) +a ??c 0 -- a + (c ?? 0) ← not (a ?? 0) + c *x ??y 1 -- x * (y ?? 1) ← not (x ?? y) * 1 The outer prefix op binds the inner prefix subexpression as its **left** operand, regardless of operator precedence. With two same-precedence ops side by side this is easy to misread: */a b c -- (a/b) * c ← NOT (a*b)/c /*a b c -- (a*b) / c ← NOT (a/b)*c +-a b c -- (a-b) + c ← NOT (a+b)-c -+a b c -- (a+b) - c ← NOT (a-b)+c The runtime emits a `hint:` diagnostic when one of these four pairs appears at a prefix position, since the parse order disagrees with the natural left-to-right reading. To force the other grouping, swap the ops or bind the inner result first: -- Want (a*b)/c with a=6, b=2, c=3: r=*a b;/r c -- bind, then divide → 4 /*a b c -- equivalent, swapping the prefix-pair order [Infix precedence] Standard mathematical precedence (higher binds tighter): 6=`*` `/` 5=`+` `-` `+=` 4=`>` `<` `>=` `<=` 3=`=` `!=` 2=`&` 1=`|` 0=`??` (binds looser than every arithmetic/boolean op; tighter than `>>`) Function application binds tighter than all infix operators: f a + b -- (f a) + b, NOT f(a + b) x * y + 1 -- (x * y) + 1 (x + y) * 2 -- parens override precedence Each nested prefix operator saves 2 tokens (no `(` `)` needed). Flat prefix like `+a b` saves 1 char vs `a + b`. Across 25 expression patterns, prefix notation saves **22% tokens** and **42% characters** vs infix. See [research/explorations/prefix-vs-infix/](research/explorations/prefix-vs-infix/) for the full benchmark. Disambiguation: `-` followed by one atom is unary negate, followed by two atoms is binary subtract. [Operands] Operator operands are **atoms** (literals, refs, field access), **nested prefix operators**, or **known-arity function calls**. The prefix-binop operand parser dispatches to call parsing when the ident at the cursor is a known-arity user fn or builtin AND the next token can start another operand: wh >len q 0{body} -- parses as wh > (len q) 0 { body } +f g h -- if f is 1-arity: BinOp(+, Call(f, [g]), h) -lnx 5 lnx 3 -- BinOp(-, Call(lnx, [5]), Call(lnx, [3])) dbl 5 -- Negate(Call(dbl, [5])) - unary on a call This parallels the `??` precedent: `??x default` accepts a call expression on the value side. Applies to every prefix-binop family member - `+`, `-`, `*`, `/`, comparisons, `&`, `|`, `+=` - and to unary negate when the call consumes the only operand. The same expansion also applies to the then/else slots of the prefix-ternary family (`?=cond a b`, `?>cond a b`, …) and the `?h cond a b` keyword form, so `?h =a b sev sc "NONE"` parses `sev sc` as a nested call without parens or a bind-first. Bare locals that shadow a user fn name still resolve via `Ref` rather than expanding into a zero-arg call, so `&e f{...}` where `f` is a local still parses as the bool operator with two refs. When the call expansion isn't available (the ident is a local that shadows a fn name, or the call's arity doesn't fit the remaining tokens), bind the call result first: r=fac p;*n r -- bind, then operate - always unambiguous **Negative literals vs binary minus**: the lexer greedily includes a leading `-` into number tokens. `-1`, `-7`, `-0` are all number literals at fresh-expression positions. To subtract from zero at the start of a statement, use a space: `- 0 v` (Minus token, then `0`, then `v`). f v:n>n;-0 v -- WRONG: -0 is Number(-0.0); v is a stray token f v:n>n;- 0 v -- OK: binary subtract: 0 - v = -v The lexer splits a glued negative literal back into `Minus + Number` when the previous token is one of `;`, `\n`, `=`, `{`, `(`, or `-`. The `-` context covers the operand slot of an outer prefix-minus, so `- -0 a b` lexes as `-, -, 0, a, b` and parses as `Subtract(Subtract(0, a), b)` = `-a - b` rather than tripping `ILO-P020`. Negative literals after an Ident, `[`, or another prefix binop (`+`, `*`, `/`) stay glued so call args (`at xs -1`), list literals (`[-2 1 3]`), and binary operands (`+a -3`) read naturally. **Subtraction spacing convention**: for general subtraction at statement position, write `a - b` with spaces on **both** sides. `a -b` (glued, no space before the `-`) is not a binary subtract: the lexer packs `-b` into a negative-literal token because the previous token (`a`, an Ident) is one of the keep-glued contexts above. That's deliberate so call args and list elements read naturally, but it means `0 -1.5` is a parse error (`ILO-P001: expected declaration, got number `-1.5`` with a tailored hint pointing at this rule). For a bare negative value as an expression, wrap in parens: `(-1.5)`. STRING LITERALS: Text values are written in double quotes.

"hello\nworld" -- two-line string "col1\tcol2" -- tab-separated spl text "\n" -- split file content into lines spl pdf "\f" -- split pdftotext output into pages [Triple-quoted strings: `"""..."""`] Same surface as `"..."` (same escape decoding, same `{name}` interpolation) with two extra affordances: 1. Raw newlines are allowed inside the literal, so multi-line content does not need `cat`-concatenation or `\n` escapes. 2. When the closing `"""` sits on its own line, the leading newline is dropped and the common leading whitespace (matching the indent of the closing-`"""` line) is stripped from every content line. The terminating `\n` of the last content line is preserved. This is the Python PEP 257 / Rust `indoc!` convention, so indented source produces clean output. banner>t """ line one line two """ -- value is "line one\nline two\n" inline>t """foo bar""" -- value is "foo\n bar" (no dedent: closing inline) len """hello""" -- 5 (single-line form, no newline) len """""" -- 0 (empty body) Inside `"""..."""` a single `"` is literal: only `"""` ends the literal. Escapes (`\n`, `\t`, ...) and `{name}` interpolation decode identically to the single-quoted form, so triple-quoted is a drop-in upgrade rather than a parallel surface. [Interpolation: `{name}`] A bare `{name}` slot inside a double-quoted string desugars at parse time to a `fmt` call with the binding looked up by name. Manifesto principle 1: `"hello {name}"` is cheaper for an agent to write than the verbose `fmt "hello {}" name`, and both produce the same AST so they cost nothing extra at verify or run time. greet name:t>t fmt "hello {name}" -- desugars to: fmt "hello {}" name pair a:t b:t>t fmt "{a} and {b}" -- multiple slots, resolved left-to-right with-braces name:t>t fmt "{{json}} {name}" -- {{ / }} escape to literal { / } Scope (deliberately tight to keep the surface predictable): Only single-identifier slots matching the ident regex (`[a-z][a-z0-9]*(-[a-z0-9]+)*`). `{a-b}` works; `{Foo}`, `{x + 1}`, `{ }` pass through verbatim. `{{` / `}}` escape to literal `{` / `}`, but only inside strings that actually contain at least one `{ident}` slot. Strings with no interpolation slot keep `{{` / `}}` verbatim so existing programs (e.g. JSON templates) are not silently rewritten. Bare `{}` keeps its existing meaning as a positional placeholder filled by trailing args of the enclosing `fmt` call. Mixing `{ident}` and bare `{}` in the same string is left verbatim: pick one style per string. Use `fmt "{name} {} done" other` and the parser keeps the `{name}` literal so the bare `{}` resolves to `other`, or write `"{name} {other} done"` and drop the trailing arg. Undefined `{name}` slots surface as a normal ILO-T004 undefined-variable diagnostic against the desugared `fmt` arg, not a silent empty substitution. Interpolation does not apply in pattern literals (`"foo":` arm of a match) - literal patterns stay literal. @@ -13,9 +14,10 @@ MATCH ARMS: `"gold":body`=literal text `42:body`=literal number `~v:body`=ok - b CALLS: Positional args, space-separated, no parens: get-user uid send-email d.email "Notification" msg charge pid amt [Call Arguments] Call arguments can be atoms or prefix expressions: fac -n 1 -- Call(fac, [Subtract(n, 1)]) fac +a b -- Call(fac, [Add(a, b)]) g +a b c -- Call(g, [Add(a,b), c]) - 2 args fac p -- Call(fac, [Ref(p)]) Use parentheses when you need a full expression (including another call) as an argument: f (g x) -- Call(f, [Call(g, [x])]) Known-arity calls can also chain directly without parens — the parser consumes exactly the inner call's arity when an ident with a registered arity follows the outer call: abs atan2 1 1 -- Call(abs, [Call(atan2, [1, 1])]) abs rndn 0 0.1 -- Call(abs, [Call(rndn, [0, 0.1])]) abs clamp 5 0 10 -- Call(abs, [Call(clamp, [5, 0, 10])]) pow atan2 1 1 2 -- Call(pow, [Call(atan2, [1, 1]), 2]) This works for every builtin and user fn whose arity is known at parse time. If the inner call is variadic or unknown-arity (e.g. `fmt`, custom name with no signature on this side of the file), wrap it in parens to disambiguate. RECORDS: Named, nominal product types - the structured-data shape (cf. `M k v` maps, which are dynamic and homogeneous). Reach for a record when fields are fixed and statically known; reach for a map when keys are dynamic or the shape varies at runtime. Define: type point{x:n;y:n} Fields separated by `;`. Each field is `name:type`. Type sigils match the rest of the language (`n`, `t`, `b`, `L n`, `O t`, `M t n`, another record name). Construct (type name as constructor): p=point x:10 y:20 Space-separated `field:value` pairs, no braces, no commas. Constructor arity and field types are checked at verify time (ILO-T021/T022 surface at update sites; ILO-T019 on missing field at access). Access: p.x -- strict: missing field is verifier error ILO-T019 / runtime ILO-R005 p.?x -- tolerant: nil if field missing, value is nil, or value isn't a record. Returns `O T`. See [Safe Field Navigation]. ord.addr.country -- chains across nested records Records are **nominal**: `type a{x:n}` and `type b{x:n}` are distinct types even though their fields match. A function `f p:point>n` won't accept a `b` value. Pass `_` (Unknown) when you genuinely want to accept any record shape. The `.field` / `.N` chain also applies to any parenthesised expression, so a call result can be read directly without binding to a name first: (at rows i).2 -- numeric dot-index on a call result (p with x:30).x -- field access on a record-update map (i:n>n;(at rs i).2) ixs -- inside an inline lambda body Destructure: {x;y}=p Binds `x` to `p.x` and `y` to `p.y`. All named fields must exist on the record. Update: ord with total:fin cost:sh [Display order] `prnt` and `fmt "{}"` render records with fields sorted lexicographically by name, regardless of declared or insertion order. The same rule applies on every engine (tree, VM, Cranelift JIT), so `diff` of stdout across engines is stable and safe for agent self-verification. `jdmp` JSON output already canonicalises keys the same way. [Field names at dot-access] After `.` or `.?`, the parser accepts any identifier-shaped token as a field name, including: **Reserved keywords** - `r.type`, `r.if`, `r.use`, `r.true`, `r.nil`. JSON keys commonly mirror language keywords and dot-access must just work. **camelCase** - `r.cvssMetricV31`, `r.userId`. Real-world JSON from APIs is rarely snake_case. **Leading uppercase** - `r.Items`, `r.UserName`. PascalCase keys from .NET / Java backends are first-class. **snake_case** - `r.type_id`, `r.user_name`. **kebab-case** - `r.x-request-id` (requires the leading segment to be an identifier). These relaxations are scoped to post-dot position only - top-level identifiers still follow the standard naming rules. TOOLS (EXTERNAL CALLS): tool "" > timeout:,retry: tool get-user"Retrieve user by ID" uid:t>R profile t timeout:5,retry:2 Tool declarations are verified statically like functions - call sites are type-checked and arity-checked. At runtime, tool calls dispatch through a provider configured via `--tools `: { "tools": { "get-user": { "url": "https://api.example.com/get-user", "method": "POST", "timeout_secs": 5, "retries": 2, "headers": { "Authorization": "Bearer token" } } } } ilo serialises call arguments as `{"args": [...]}` (JSON array), sends them to the endpoint, and deserialises the response body back to an ilo value. HTTP 2xx → `Ok(response)`, non-2xx → `Err("HTTP : ...")`. Without `--tools`, tool calls return `Ok(_)` (stub behaviour). **Value ↔ JSON mapping:** `n`=number `t`=string `b`=boolean `_`=null `L n`=array `R ok err`=`{"ok": ...}` or `{"err": ...}` record=object Tool return type `>t` is the escape hatch - any JSON response is coerced to a text string without parsing. -IMPORTS: Split programs across files with `use`: use "path/to/file.ilo" -- import all declarations use "path/to/file.ilo" [name1 name2] -- import only named declarations All imported declarations merge into a flat shared namespace - no qualification, no `mod::fn` syntax.

PATTERNS (FOR LLM GENERATORS): [Bind-first pattern] Always bind complex expressions to variables before using them in operators. Operators only accept atoms and nested operators as operands - not function calls. -- DON'T: *n fac -n 1 (fac is an operand of *, not a call) -- DO: r=fac -n 1;*n r (bind call result, then use in operator) [Recursion template] >;;...;;combine 1. **Guard**: base case returns early - `<=n 1 1` (or `<=n 1{1}`) 2. **Bind**: bind recursive call results - `r=fac -n 1` 3. **Combine**: use bound results in final expression - `*n r` [Factorial] fac n:n>n;<=n 1 1;r=fac -n 1;*n r `<=n 1 1` - braceless guard: if n <= 1, return 1 `r=fac -n 1` - recursive call with prefix subtract as argument `*n r` - multiply n by result [Fibonacci] fib n:n>n;<=n 1 n;a=fib -n 1;b=fib -n 2;+a b `<=n 1 n` - braceless guard: return n for 0 and 1 `a=fib -n 1;b=fib -n 2` - two recursive calls, each with prefix arg `+a b` - add results [Tail-call optimisation] ilo guarantees that **tail calls do not consume host-stack frames**. A function that recurses only in tail position can run to arbitrary depth — the runtime trampolines the call by rebinding parameters in place rather than pushing a frame. The manifesto's "Constrained" rule (every feature must pay for itself in tokens) vetoed adding a `loop` keyword. Instead, tail-recursive accumulator patterns are the canonical idiom for iteration beyond what `@` foreach covers, and the TCO guarantee makes them safe at any depth. A call is in **tail position** when its return value is the function's return value: the last statement of the body, the expression of a `ret` statement, an arm of a tail-position `?` match, or the body of a braceless guard. Calls inside `@` foreach, `@` range, `wh` loops, or as operands of further computation are NOT in tail position. -- Tail-recursive countdown — runs to arbitrary depth. count-down n:n>n;=n 0 0;count-down -n 1 -- Tail-recursive accumulator — sums a list without growing the host stack. sum-acc xs:L n acc:n>n;empty=len xs;=empty 0 acc;sum-acc tl xs +acc hd xs Constraints on the tail-call peephole: The callee must be a direct user-defined function name (not a FnRef in scope, not a closure, not a builtin, not a tool). The call must have no auto-unwrap (`!` / `!!`) — those forms inspect the result before deciding whether to propagate. These constraints leave the common shapes (recursive accumulators, state machines, mutual recursion via direct names) covered. Other shapes still recurse the host stack as before; for deep recursion through non-tail-eligible shapes, restructure into an accumulator. Tree interpreter and bytecode VM (`--vm`) support shipped in 0.12.x; the VM emits `OP_TAILCALL` for tail-position user-fn calls and reuses the current call frame instead of pushing a new one, so depth is bounded only by available heap. Cranelift (`--jit`, AOT) gains matching `return_call` lowering in a subsequent PR; until then, deep tail-recursion under the JIT/AOT path recurses the host stack and is bounded by it. [Multi-statement bodies] Semicolons separate statements. Last expression is the return value. f x:n>n;a=*x 2;b=+a 1;*b b -- (x*2 + 1)^2 Bodies may also be written across multiple newline-separated lines, indented under the signature. The parser stays inside the same function body while it sees an open bracket (`[`, `(`, `{`) or a pipe operator continuation. This makes long literals and multi-line conditional pipelines readable without semicolons: f x:n>n a=*x 2 b=+a 1 *b b g>L n [10, 20, 30, 40, 50, 60, 70, 80] Statement separation reverts to standard rules once brackets close. A blank line ends the current declaration. Windows CRLF (`\r\n`) is normalised to `\n` before lexing, so files edited on Windows parse identically to Unix-line-ending files. [Multi-function files] Functions in a file are separated by **newlines**. The parser strips all newlines, so the token stream is flat. After parsing each function body, the parser uses the next newline-delimited boundary to start the next declaration. A non-last function body's **final expression must not be a bare variable reference (`Ref`) or a function call**, because the parser greedily reads following tokens as additional call arguments. Safe endings prevent this: Binary operator=`+n 0`, `*x 1`=✓=fixed arity - no greedy loop Index access=`xs.0`, `rec.field`=✓=returns `Expr::Index`, not `Ref` Match block=`?v{…}`=✓=ends with `}` ForEach block=`@x xs{…}`=✓=ends with `}` Parenthesised expr=`(x>>f>>g)`=✓=ends with `)` Record constructor=`point x:1 y:2`=✓=parses as `Expr::Record`, not `Ref` Text/number literal=`"ok"`, `42`=✓=literal, not `Ref` Bare variable (`Ref`)=`n`, `result`=✗=greedy loop fires Bare function call=`len xs`, `f a`=✗=greedy loop fires The **last function in a file** can end with anything - greedy parsing stops at EOF. -- Non-last functions: end with a binary expression digs n:n>n;t=str n;l=len t;+l 0 -- +l 0 = l (binary, safe) clmp n:n lo:n hi:n>n;n hi hi;+n 0 -- +n 0 = n (binary, safe; `clamp` is a builtin) -- Last function: bare call is fine sz xs:L n>n;len xs -- EOF - greedy loop stops naturally To use a pipe chain in a non-last function, wrap it in parentheses: dbl-inc x:n>n;(x>>dbl>>inc) -- parens prevent >> from consuming next function's name inc-sq x:n>n;x>>inc>>sq -- last function - no parens needed [DO / DON'T] -- DON'T: fac n:n>n;<=n 1 1;*n fac -n 1 -- ↑ *n sees fac as an atom operand, not a call -- DO: fac n:n>n;<=n 1 1;r=fac -n 1;*n r -- ↑ bind-first: call result goes into r, then *n r works -- DON'T: +fac -n 1 fac -n 2 -- ↑ + takes two operands; fac is just an atom ref -- DO: a=fac -n 1;b=fac -n 2;+a b -- ↑ bind both calls, then combine -ERROR DIAGNOSTICS: ilo verifies programs before execution and reports errors with stable codes, source context, and suggestions. [Error codes] Every error has a stable `ILO-` code. The letter is the namespace - the phase that raised the diagnostic - so agents and tools can route on prefix without parsing the message. Numeric ranges are reserved per namespace with generous gaps, so future codes slot in cleanly and the contract is forward-compatible. `ILO-L000-099`=L=Lexer / tokenisation=active `ILO-P100-199`=P=Parser / syntax=active `ILO-N200-299`=N=Names / resolution=reserved `ILO-I300-399`=I=Imports=reserved `ILO-T400-499`=T=Types=active `ILO-V500-599`=V=Verifier (post-type checks)=reserved `ILO-R600-699`=R=Runtime=active `ILO-D700-799`=D=Deprecation warnings=reserved `ILO-E800-899`=E=Engine-specific limitations=reserved `ILO-S900-999`=S=Skill / spec system=reserved **Historical codes.** ilo shipped with flat numbering inside each namespace - `ILO-L001`, `ILO-P001`, `ILO-T001`, `ILO-R001`, `ILO-W001`, all starting at 001. Those codes remain valid forever. The hundreds-block allocation above applies to new codes from now on, and a cross-engine regression test asserts every emitted code lives in a documented range. **Reserved namespaces.** `N`, `I`, `V`, `D`, `E`, `S` carry no codes today. They are forward declarations so the first code in each category slots into its own range without conflicting with the active namespaces. `D` is earmarked for deprecation warnings: when a feature is scheduled for removal it emits an `ILO-D7xx` warning at compile time without failing the build. Use `--explain` to see a detailed explanation: ilo --explain ILO-T004 [Source context] Errors point at the relevant source location with a caret: error[ILO-T005]: undefined function 'foo' (called with 1 args) --> 1:9 1 | f x:n>n;foo x = note: in function 'f' = suggestion: did you mean 'f'? Parser, verifier, and runtime errors all show source spans. The verifier uses the enclosing statement span as the best available location for expression-level errors. [Suggestions] The verifier provides context-aware hints: **Did you mean?** - Levenshtein-based suggestions for undefined variables, functions, fields, and types **Type conversion** - suggests `str` for n→t, `num` for t→n **Missing arms** - lists uncovered match patterns with types **Arity** - shows expected parameter signature [Error output formats] --ansi / -a ANSI colour (default for TTY) --text / -t Plain text (no colour) --json / -j JSON (default for piped output) --no-hints / -nh Suppress idiomatic hints --silent / -s Suppress program stdout (mainly for --bench; see below) NO_COLOR=1 Disable colour (same as --text) **`--silent` / `-s`.** Suppresses the program's own stdout (`prnt`, `prnv`, `jprn`, etc.) for the duration of execution. Designed for `ilo --bench`: combined with `--json` it lets agent harnesses (e.g. persona cost rollup) consume the bench JSON envelope on stdout without it being drowned in the benchmarked function's own output. Stderr is never silenced, so genuine errors still surface. Diagnostic output (including the bench JSON envelope and the human-readable bench summary block) is always emitted on stdout regardless of `--silent` — the flag only redirects program-level prints. Unix only (no-op on Windows for the program-stdout half; bench output still reaches stdout there). JSON error output follows a structured schema with `severity`, `code`, `message`, `labels` (with spans), `notes`, and `suggestion` fields. Runtime errors raised from the Cranelift JIT (opt-in via `--jit`) populate `labels` with the source span of the failing operation, matching tree and VM behaviour. Span coverage threads through every JIT runtime helper (unwrap, panic-unwrap, list-get, slice, index, jpth, mget, record-field strict access, builtin dispatch, dynamic call); AOT-compiled binaries inherit the same coverage. Pre-v0.11.6 builds surfaced `{"labels":[]}` for these shapes - if you see an empty labels array on a runtime error, the binary is out of date. AOT binaries also install an async-signal-safe handler in `ilo_aot_init` that catches fatal signals (SIGSEGV, SIGBUS, SIGFPE, SIGILL, SIGABRT) and writes a single JSON line on stderr identifying the signal before the process terminates with the conventional 128+signo exit code. The diagnostic uses `ILO-R015` (AOT runtime fault). Without the handler, a hard fault inside compiled native code would leave the process with raw signal exit (e.g. 139 for SIGSEGV) and no diagnostic — agents driving ilo couldn't distinguish a clean non-zero exit from a hard fault. A SIGSEGV from an AOT binary is always a bug in ilo (codegen or runtime helper); file an issue with the source program and the JSON line. AOT binaries also install an async-signal-safe handler in `ilo_aot_init` that catches fatal signals (SIGSEGV, SIGBUS, SIGFPE, SIGILL, SIGABRT) and writes a single JSON line on stderr identifying the signal before the process terminates with the conventional 128+signo exit code.

A SIGSEGV from an AOT binary is always a bug in ilo (codegen or runtime helper); file an issue with the source program and the JSON line. [Top-level program output] For a program whose entry function returns a Result, the `~`/`^` wrapper is split across streams and exit codes so shell callers do not have to strip a prefix: `~v` (Ok)=`v` (bare)=-=0 `^e` (Err)=-=`^e`=1 any non-Result=`v`=-=0 In `--json` mode the value is always wrapped (`{"schemaVersion": 1, "ok": v}` / `{"schemaVersion": 1, "error": {...}}`) and emitted to stdout; exit codes match the plain-mode table. The `schemaVersion` field was added in 0.12.1 to every CLI `--json` envelope (`run`, `graph`, `--ast`, `serv`, `tools --json`, `spec --json`) so agents can route on a single field across every command. See `JSON_OUTPUT.md` for the full audit table. `Display` on `Value::Ok` / `Value::Err` still renders `~v` / `^e` in every other context (nested values, `prnt`, REPL prompts, error messages, debug output) - only the top-level program-return print path is split. The contract applies uniformly to in-process runners (`ilo prog.ilo`, `--vm`, `--jit`) and to AOT-compiled standalone binaries from `ilo compile`. Both strip the top-level `~`/`^` wrapper on stdout, route `^e` to stderr, and use the same exit codes - output is byte-for-byte identical across every backend. **Auto-echo suppression for `prnt` + status sentinel.** When the entry function has at least one *unconditional top-level* `prnt` call AND the tail expression is a bare wrapped string literal (`~"text"` or `^"text"`), the top-level auto-echo is suppressed. The wrapped literal is treated as a status sentinel rather than a value the caller wants captured. Without this rule, a function shaped like `m>R t t;prnt "report";~"ok"` emits `report\nok\n` on stdout and shell callers piping the output have to strip the trailing `ok`. The rule does NOT fire when (a) there is no `prnt` in the body — `m>R t t;~"ok"` still prints `ok` because the wrapped literal IS the program's output (the `cli-tasks-save-ok.ilo` pattern); (b) the `prnt` is nested inside a guard, loop, or match arm — those are conditional and the `prnt` may never run; (c) the tail is `~v` where `v` is a binding or call — that's a real return value. `^"text"` errors still go to stderr with exit 1; the suppression rule never silently swallows an Err. Pinned by `tests/regression_tilde_str_noecho.rs` and `examples/tilde-str-noecho.ilo`. [Idiomatic hints] After successful execution, ilo scans the source for non-canonical forms and emits hints to stderr: hint: `==` → `=` saves 1 char (both mean equality in ilo) hint: `length` → `len` (canonical short form) Builtin alias hints appear at most once per program (the first long-form name found). In JSON mode, hints appear as `{"hints":["..."]}` on stderr. Suppress with `--no-hints` / `-nh`. [CLI invocation] ilo 'code' [args...] -- inline program; default-runs the entry function ilo program.ilo [func] [args] -- if `func` is omitted and the file declares exactly one function, that function runs automatically ilo run program.ilo [func] [a] -- verb form; same dispatch as the bare positional ilo check program.ilo [--json] [--strict] -- run the verifier without executing (exit 0 = clean; --strict treats warnings as exit-code errors) ilo build program.ilo -o out -- AOT compile to a standalone binary (alias for `compile`) ilo program.ilo --ast -- print parsed AST as JSON and exit ilo --explain ILO-T004 -- print error explanation and exit ilo help ai -- compact AI spec to stdout (= contents of ai.txt) ilo serv -- long-lived JSON request/response loop ilo --max-ast-depth N -- cap parser nesting at N (default 256; protects `ilo serv` and other untrusted-source paths from DoS payloads, raises ILO-P103) ilo --max-runtime SECS -- cap wall-clock runtime at SECS (default 60; 0 disables; raises ILO-R016) ilo --max-output-bytes BYTES -- cap stdout output at BYTES (default ~100 MB; 0 disables; raises ILO-R017) **Production-safety guards (`ILO-R016`, `ILO-R017`).** `ilo run` caps wall-clock runtime at 60 s and stdout output at ~100 MB by default. A runaway loop (missing increment, recursion with no base case) aborts with `ILO-R016` once the time budget hits, instead of burning CPU forever; a `prnt` loop without termination aborts with `ILO-R017` once the byte budget hits, instead of filling the agent transcript with megabytes of garbage. Both guards write a structured diagnostic to stderr and exit 1. Defaults are well above any legitimate program (real agent tasks finish under 10 s and produce kilobytes); raise with `--max-runtime SECS` / `--max-output-bytes BYTES`, set either to `0` to disable. The guards were installed by the mandelbrot persona report (2026-05-20) which spun in an infinite loop and wrote 165 MB of stdout before the harness intervened. **Verb-noun aliases.** `ilo run ` is an exact alias for the bare positional `ilo ` - same dispatch, same engine selection, same arg handling. `ilo build -o ` is an alias for `ilo compile -o `. Both exist to match the toolchain conventions used by `cargo`, `go`, and `zero` so agents and humans can guess the command name without consulting the help text. The bare positional forms remain fully supported for backwards compatibility; nothing has been removed. **`ilo check`.** Standalone verifier invocation: lex, parse, resolve imports, and run the type verifier without proceeding to bytecode compilation or execution. Exit code 0 means the program is well-typed and verifier-clean; exit code 1 means at least one diagnostic was emitted on stderr. The output mode follows the global flags (`--json` for NDJSON diagnostics, `--text` for plain text, `--ansi` for coloured output; auto-detected when omitted - JSON when stderr is not a TTY, ANSI otherwise). `ilo check` works on both files and inline code; on a syntactically-broken input it still reports the parse error rather than crashing, which is important for editor and agent loops that may feed in half-written programs. **`ilo check --strict`.** Treats every warning-severity diagnostic (ILO-T032 bare `fmt`, ILO-T033 bare `mset` / `+=` / `mdel`, ILO-W002 `@x (jpar! …){…}` steering to `jpar-list!`, future warning codes) as a hard exit-code failure. The diagnostic stream itself is unchanged: warnings still emit with `severity: "warning"` in the JSON output, so editor integrations that route by severity stay correct. Only the exit code is elevated. CI harnesses that gate merges on `ilo check` should use `--strict` so warnings can't slip through silently; for interactive use, the default (warnings-are-advisory) is the right behaviour. **Default-run.** Inline programs (`ilo 'code'`) and single-function files run their entry function with the remaining CLI args; no explicit function name needed. Multi-function files auto-pick a function called `main` when no positional func arg is supplied. The same heuristic applies to the explicit engine flags - `--vm` and `--jit` both auto-pick `main` on multi-fn files, matching the default-engine behaviour. With no `main` declared, supply a function-name argument. **AOT entry-pick.** `ilo compile file.ilo -o out` (alias `ilo build`) follows the same entry-pick rules as the in-process engines: a single user-defined function is used directly; on multi-function files the entry is `main` if defined, otherwise the explicit positional `func` arg (`ilo compile file.ilo -o out run`); otherwise the compile fails with `ILO-E801` and exits 1 without writing a binary. AOT does not fall back to "first declared function" - that historical default produced binaries that called the wrong entry symbol and SIGSEGV'd at runtime. **Default engine.** The bytecode register VM is the default execution path. It supports every opcode (closures with Phase 2 capture, listview windows, fused len-of-filter, every modern shape), and avoids the JIT compile-and-bail cost paid by the pre-v0.11.9 Cranelift-first default whenever a program touched an opcode the JIT couldn't handle. Cranelift JIT is opt-in via `--jit`; on opt-in, the JIT runs hot numeric loops and falls back to the VM on bailout. Phase 2 captures run natively on every public backend - VM, JIT, and AOT (`ilo compile`); AOT embeds the postcard `CompiledProgram` blob into the binary's `.rodata` so dispatch helpers can re-enter the VM on user-fn callbacks the same way the in-process runners do. For long-running workloads where the JIT pays for itself, opt in explicitly; for most agent workloads the VM is the right default. **Tree-walker is internal-only.** The tree-walking interpreter is no longer user-selectable: `--run-tree` and its `--run` alias were removed from the public CLI in 0.12.1 (they now error with the unknown-flag guard). The interpreter stays in-tree as the dispatch target for HOF / regex / fmt-variadic / IO / sleep / ct / rsrt / closure-bind-ctx shapes the VM and Cranelift haven't lifted natively yet - the VM bails to it transparently for the ops listed by `is_tree_bridge_eligible` (`rgx`, `rgxall`, `rgxall1`, `rgxall-multi`, `rgxsub`, `fmt`, `fmt2`, `rd`, `rdb`, `rdjl`, `rdin`, `rdinl`, `sleep`, `lsd`, `walk`, `glob`, `dirname`, `basename`, `pathjoin`, `fsize`, `mtime`, `isfile`, `isdir`, `run`, `env-all`, `jkeys`, `tz-offset`, `ct` 2-arg and 3-arg, `rsrt` 2-arg and 3-arg, `dur-parse`, `dur-fmt`, and the closure-bind ctx variants of `map`/`flt`/`fld`/`srt`). Cross-engine parity for those shapes is pinned by `tests/regression_builtin_bridge.rs` and `tests/regression_tree_bridge_invariants.rs`. 0.13.0+ is on track for a hard drop once the bridge consumers are lifted natively and the shared runtime types (`Value`, `MapKey`, `RuntimeError`, math helpers) are extracted from `src/interpreter/` to a non-engine module. **Subcommand dispatch.** The first positional argument is interpreted as a function name when it has the shape of an ilo identifier - `[a-z][a-z0-9]*(-[a-z0-9]+)*` - so `ilo file.ilo list-orders` routes to the `list-orders` function. Args that don't match the ident shape (file paths like `/tmp/data.json`, numbers, sigils, bracketed lists, anything with a `.` or `/`) route to `main` (or the entry function) as a positional CLI arg instead. Trailing dashes (`foo-`), doubled dashes (`foo--bar`), and negative numbers (`-1`) are not idents and pass through as data. **Unknown `--flag` guard.** Any token in the positional tail matching the clean long-flag shape `--word` or `--word-with-dashes` that isn't a recognised flag is rejected upfront with `error: unrecognised flag '--'. Use 'ilo --help' for valid flags. To pass it as a literal arg, separate with '--' first.` and exit 1. This prevents `ilo main.ilo --engine tree` from silently consuming `--engine` as a positional arg (which used to surface as misleading `ILO-R012 no functions defined` or `ILO-R004 main: expected N args, got N+1`). To pass a hyphen-prefixed token through as literal data, place the `--` separator first: `ilo main.ilo -- --foo`. Anything after the first `--` is data. Tokens with `=` (`--key=val`), trailing or doubled dashes (`--foo-`, `--foo--bar`), and negative numbers (`-1`) are not clean flag shapes and pass through unchanged. **Text-typed params.** When the entry function declares a parameter of type `t`, the CLI passes the raw arg through without numeric coercion. `ilo 'f x:t>t;x' 42` returns the string `"42"`, not the number 42. **Exit codes.** A program returning `Value::Err` (or `^reason` from the entry function) exits with code 1 and prints the err payload on stderr. `~v` (Ok) and any non-Result return value exit 0. Verifier and parser errors exit 2. **List args from the CLI.** Comma-separated args become `L n` or `L t` automatically: `ilo 'f xs:L n>n;sum xs' 1,2,3`. +ERROR DIAGNOSTICS: ilo verifies programs before execution and reports errors with stable codes, source context, and suggestions.

Exit code 0 means the program is well-typed and verifier-clean; exit code 1 means at least one diagnostic was emitted on stderr. The output mode follows the global flags (`--json` for NDJSON diagnostics, `--text` for plain text, `--ansi` for coloured output; auto-detected when omitted - JSON when stderr is not a TTY, ANSI otherwise). `ilo check` works on both files and inline code; on a syntactically-broken input it still reports the parse error rather than crashing, which is important for editor and agent loops that may feed in half-written programs. **`ilo check --strict`.** Treats every warning-severity diagnostic (ILO-T032 bare `fmt`, ILO-T033 bare `mset` / `+=` / `mdel`, ILO-W002 `@x (jpar! …){…}` steering to `jpar-list!`, future warning codes) as a hard exit-code failure. The diagnostic stream itself is unchanged: warnings still emit with `severity: "warning"` in the JSON output, so editor integrations that route by severity stay correct. Only the exit code is elevated. CI harnesses that gate merges on `ilo check` should use `--strict` so warnings can't slip through silently; for interactive use, the default (warnings-are-advisory) is the right behaviour. **Default-run.** Inline programs (`ilo 'code'`) and single-function files run their entry function with the remaining CLI args; no explicit function name needed. Multi-function files auto-pick a function called `main` when no positional func arg is supplied. The same heuristic applies to the explicit engine flags - `--vm` and `--jit` both auto-pick `main` on multi-fn files, matching the default-engine behaviour. With no `main` declared, supply a function-name argument. **AOT entry-pick.** `ilo compile file.@ -o out` (alias `ilo build`) follows the same entry-pick rules as the in-process engines: a single user-defined function is used directly; on multi-function files the entry is `main` if defined, otherwise the explicit positional `func` arg (`ilo compile file.@ -o out run`); otherwise the compile fails with `ILO-E801` and exits 1 without writing a binary. AOT does not fall back to "first declared function" - that historical default produced binaries that called the wrong entry symbol and SIGSEGV'd at runtime. **Default engine.** The bytecode register VM is the default execution path. It supports every opcode (closures with Phase 2 capture, listview windows, fused len-of-filter, every modern shape), and avoids the JIT compile-and-bail cost paid by the pre-v0.11.9 Cranelift-first default whenever a program touched an opcode the JIT couldn't handle. Cranelift JIT is opt-in via `--jit`; on opt-in, the JIT runs hot numeric loops and falls back to the VM on bailout. Phase 2 captures run natively on every public backend - VM, JIT, and AOT (`ilo compile`); AOT embeds the postcard `CompiledProgram` blob into the binary's `.rodata` so dispatch helpers can re-enter the VM on user-fn callbacks the same way the in-process runners do. For long-running workloads where the JIT pays for itself, opt in explicitly; for most agent workloads the VM is the right default. **Tree-walker is internal-only.** The tree-walking interpreter is no longer user-selectable: `--run-tree` and its `--run` alias were removed from the public CLI in 0.12.1 (they now error with the unknown-flag guard). The interpreter stays in-tree as the dispatch target for HOF / regex / fmt-variadic / IO / sleep / ct / rsrt / closure-bind-ctx shapes the VM and Cranelift haven't lifted natively yet - the VM bails to it transparently for the ops listed by `is_tree_bridge_eligible` (`rgx`, `rgxall`, `rgxall1`, `rgxall-multi`, `rgxsub`, `fmt`, `fmt2`, `rd`, `rdb`, `rdjl`, `rdin`, `rdinl`, `sleep`, `lsd`, `walk`, `glob`, `dirname`, `basename`, `pathjoin`, `fsize`, `mtime`, `isfile`, `isdir`, `run`, `env-all`, `jkeys`, `tz-offset`, `ct` 2-arg and 3-arg, `rsrt` 2-arg and 3-arg, `dur-parse`, `dur-fmt`, and the closure-bind ctx variants of `map`/`flt`/`fld`/`srt`). Cross-engine parity for those shapes is pinned by `tests/regression_builtin_bridge.rs` and `tests/regression_tree_bridge_invariants.rs`. 0.13.0+ is on track for a hard drop once the bridge consumers are lifted natively and the shared runtime types (`Value`, `MapKey`, `RuntimeError`, math helpers) are extracted from `src/interpreter/` to a non-engine module. **Subcommand dispatch.** The first positional argument is interpreted as a function name when it has the shape of an ilo identifier - `[a-z][a-z0-9]*(-[a-z0-9]+)*` - so `ilo file.@ list-orders` routes to the `list-orders` function. Args that don't match the ident shape (file paths like `/tmp/data.json`, numbers, sigils, bracketed lists, anything with a `.` or `/`) route to `main` (or the entry function) as a positional CLI arg instead. Trailing dashes (`foo-`), doubled dashes (`foo--bar`), and negative numbers (`-1`) are not idents and pass through as data. **Unknown `--flag` guard.** Any token in the positional tail matching the clean long-flag shape `--word` or `--word-with-dashes` that isn't a recognised flag is rejected upfront with `error: unrecognised flag '--'. Use 'ilo --help' for valid flags. To pass it as a literal arg, separate with '--' first.` and exit 1. This prevents `ilo main.@ --engine tree` from silently consuming `--engine` as a positional arg (which used to surface as misleading `ILO-R012 no functions defined` or `ILO-R004 main: expected N args, got N+1`). To pass a hyphen-prefixed token through as literal data, place the `--` separator first: `ilo main.@ -- --foo`. Anything after the first `--` is data. Tokens with `=` (`--key=val`), trailing or doubled dashes (`--foo-`, `--foo--bar`), and negative numbers (`-1`) are not clean flag shapes and pass through unchanged. **Text-typed params.** When the entry function declares a parameter of type `t`, the CLI passes the raw arg through without numeric coercion. `ilo 'f x:t>t;x' 42` returns the string `"42"`, not the number 42. **Exit codes.** A program returning `Value::Err` (or `^reason` from the entry function) exits with code 1 and prints the err payload on stderr. `~v` (Ok) and any non-Result return value exit 0. Verifier and parser errors exit 2. **List args from the CLI.** Comma-separated args become `L n` or `L t` automatically: `ilo 'f xs:L n>n;sum xs' 1,2,3`. FORMATTER: Dense output is the default - newlines are for humans, not agents. No flag needed for dense format: ilo 'code' Dense wire format (default) ilo 'code' --dense / -d Same, explicit ilo 'code' --expanded / -e Expanded human format (for code review) [Dense format] Single line per declaration, minimal whitespace. Operators glue to first operand: cls sp:n>t;>=sp 1000{"gold"};>=sp 500{"silver"};"bronze" [Expanded format] Multi-line with 2-space indentation. Operators spaced from operands: cls sp:n > t >= sp 1000 { "gold" } >= sp 500 { "silver" } "bronze" Dense format is canonical - `dense(parse(dense(parse(src)))) == dense(parse(src))`.

The walker is widened in later stages as HIR carries enough +information for arithmetic, branching, and the shim cases above. + +## Error namespace (`ILO-B3##`) + +| Code | Meaning | +| --- | --- | +| `ILO-B301` | `zero check`/`zero build` rejected the emitted source | +| `ILO-B302` | HIR construct not supported by the Zero backend yet | +| `ILO-B303` | `zero` compiler missing on PATH (`--0bin` only) | +| `ILO-B304` | IO failure writing artefact | +| `ILO-B305` | Entry function not found | + +All `BackendError` variants round-trip through `BackendError::to_json()` +for `ilo build --json`. + +## `--0` vs `--0bin` + +- `--0` emits `.0` source.

Slower (subprocess overhead + Zero compilation). Use + when you want a binary built by Zero's toolchain. + +Both paths produce identical `.0` source. The `--0bin` path adds the +build step on top. + +## Subprocess invocation + +``` +zero check .0 # validate (optional, fast) +zero build .0 --json --out # native binary, JSON diagnostics +``` + +The Zero backend passes `--json` by default for machine-readable +diagnostics. Both stdout and stderr are captured because Zero 0.1.2 +prints diagnostics to stdout, not stderr. The exit code is reliable. + +## Cross-target compilation + +`zero doctor` reports `target compiler: missing` on Stage 5e's pinned +build -- only affects cross-host builds. Native darwin-arm64 is fine. +`--0bin` defaults to the host target. + +## When the Zero compiler upgrades + +The pin file (`.zero-version` at the repo root) records the exact Zero +version Stage 5e targets. Upgrades require: + +1. Run the full Zero backend test suite against the new Zero version + (`cargo test --release --features cranelift --test zero_emit + --test zero_binary --test zero_capability`). +2. Update `.zero-version` and the `PINNED_ZERO_VERSION` constant in + `src/backend/zero/mod.rs`. +3. Update this matrix if syntax or builtin support changed. +4. CHANGELOG entry under the patch release. + +Pre-1.0 Zero will move fast.

The lowering pass therefore re-infers types +during the AST→HIR walk, using the same rules as the verifier (literals, +constructors, builtin return types). Where inference cannot determine a type +without re-running full type-checking, the slot is `Ty::Unknown`. This is +acceptable for Stage 5a: backends that need a concrete type can either +re-infer themselves or run their own pass over the HIR. Stage 5b can introduce +a richer type-annotation channel from the verifier if Cranelift demands it. + +## Module layout + +``` +src/hir/ +├── mod.rs public surface, re-exports +├── types.rs HIR types (mirrors verify::Ty) +├── expr.rs HIR expressions +├── decl.rs top-level declarations +├── program.rs program-level Hir struct +├── lower.rs ast::Program → hir::Program +├── raise.rs hir::Program → ast::Program (for the throwaway walker) +├── walker.rs `walk(hir, args)` — raises to AST + invokes interpreter +└── DESIGN.md +``` + +`lower.rs` is the lowering pass. `raise.rs` round-trips HIR back to AST so the +throwaway `walker.rs` can reuse the existing tree-walker for correctness tests. +This is deliberately throwaway: Stage 5f deletes `raise.rs` and `walker.rs` +once the real backends supersede them. Keeping a raise pass also gives us a +free invariant for free in Stage 5b — if the Cranelift refactor goes wrong, +the raise-to-AST path remains a working reference. + +## Departures from the AST + +The HIR differs from the AST in the following ways. Each is small and +purpose-driven; nothing is rewritten for its own sake. + +### 1. Explicit tail expressions on function bodies + +The AST represents a function body as a flat `Vec>` where the +final statement may be an `Expr` whose value is the implicit return. The HIR +splits this: + +```rust +pub struct Body { + pub stmts: Vec, // side-effecting prefix + pub tail: Option,// implicit return value, if any +} +``` + +This makes the "what's the return value?" question O(1) at every backend +instead of "scan the last statement and special-case it." Stage 5b +(Cranelift refactor) will lean on this; the alternative was re-deriving the +tail in every backend. + +### 2. Guards split by intent + +The AST encodes three different guard shapes in one `Stmt::Guard` variant +(braced conditional with no else, braced conditional with else, braceless +early-return). The HIR splits them into: + +- `Stmt::If { cond, then, else_ }` — braced conditional; `else_` is optional. +- `Stmt::GuardReturn { cond, value }` — braceless early-return. + +Negation is folded into the lowering: `!cond{body}` becomes +`If { cond: not(cond), then: body, else_: None }`. Backends don't need to +care about `negated`. + +### 3. Ternaries flattened to If-expressions + +`Expr::Ternary` and `?expr{arms}` used as a value both lower to the same +underlying form. Stage 5a keeps `Expr::Match` for `?expr{arms}` (because +patterns are richer than a true/false split) but rewrites `Ternary` to +`If` — symmetric with the statement-level split above. + +### 4. Pipes already gone + +The AST does not carry pipes — the parser desugars `x>>f>>g` into nested +calls before AST construction. Nothing to do at the HIR layer. + +### 5. Alias / Use / Error decls dropped + +`Decl::Alias` is pure sugar (resolved at verify time). `Decl::Use` is resolved +before verification. `Decl::Error` is a parser error-recovery poison node and +the verifier rejects programs that contain them. The HIR omits all three. + +### 6. Spans preserved, but optional + +Every HIR node carries an optional `Span` for diagnostics. Spans are not +load-bearing for execution; backends that don't care about them can ignore the +field. + +## Types + +`hir::Ty` mirrors `verify::Ty` exactly. We re-export the verifier's enum +rather than duplicate it so future changes to the type lattice (e.g. +introducing effect rows) propagate without a parallel update. `Ty::Unknown` +is the escape hatch for the bits of the AST whose static type isn't +determinable from a local inspection. + +## Things the HIR does NOT do (yet) + +The brief is explicit: thin in v1. The following are out of scope and tracked +as open questions for later stages. + +### Closure lifting + +The parser already lifts inline lambdas to `__lit_N` top-level functions and +emits `Expr::MakeClosure { fn_name, captures }`. The HIR carries this through +unchanged. A backend that needs strictly-typed closures (e.g. WASM Component +Model) will need its own pass to flatten captures into struct fields. Stage 5b +will add a helper if Cranelift needs one. + +### `with` / record update + +Today `Expr::With` desugars at runtime into a copy-on-write record clone. HIR +keeps `With` as a single node. A lower HIR would expand it to an explicit +clone-and-update sequence. Defer. + +### Match exhaustiveness + +The verifier checks exhaustiveness; HIR does not record the result. Backends +that care (WASM, native) can either re-derive it or trust the verifier ran. +Stage 5b: revisit if Cranelift's match emit benefits from explicit "this is +exhaustive, no default needed" markers. + +### Effect / capability annotations + +Phase 6+ work. Not modelled at HIR Stage 5a. + +## Round-trip strategy (Stage 5a only) + +The brief calls for `tests/hir_roundtrip.rs` that asserts AST-walk output +matches HIR-walk output across every `examples/*.ilo` file with an annotated +`-- run:` / `-- out:` pair. + +Stage 5a implements `hir::walk` as `lower → raise → interpreter::run`. This is +the cheapest correctness gate: it proves the lowering preserves enough +information to reconstruct an equivalent AST. Once Stage 5b lands the real +Cranelift backend driven from HIR, the raise + walker stub can go. + +## Acceptance gates met by this design + +- [x] HIR exists with module layout `src/hir/{types,expr,decl,program,lower,raise,walker}.rs` +- [x] `hir::lower(ast, verify_out) → Result` +- [x] `hir::walk(hir, args) → Value` for the round-trip test +- [x] Documented departures from AST above +- [x] Documented open questions / deferrals above + +## Open questions for Stage 5b+ + +1. **Type annotations on `Expr`.** Today every HIR expression carries an + optional `Ty` slot computed by `lower.rs`. Cranelift may want a *required* + non-`Unknown` type on every node; if so, Stage 5b extends the verifier to + emit a typed-AST output that lowering can consume directly. Decision + deferred until Cranelift's lowering pass starts being written. + +2. **Effects channel.** When ilo grows explicit effect rows (Phase 6+), the + HIR will need either an effect annotation per call or a separate "effect + map" structure. Punt. + +3. **HIR stability.** Treating HIR as a public Rust API would prevent breaking + downstream crates as new HIR nodes appear. Today it's `pub` but + undocumented as stable. Stage 5b should mark crate-internal-only via doc + comments and keep HIR private until Phase 6 settles. diff --git a/src/hir/decl.rs b/src/hir/decl.rs new file mode 100644 index 00000000..680e0b51 --- /dev/null +++ b/src/hir/decl.rs @@ -0,0 +1,48 @@ +//!

The other 84 are + pre-existing AOT-compile failures (duplicate symbol bugs, unsupported + opcodes) that this refactor is not in scope to fix. +- The 87 runtime-mismatch baselines noted in `/tmp/ilo-baselines/ + verify-mismatches.tsv` (binaries that segfault when run with no args) + do NOT affect this test — we assert object-file byte identity, not + runtime behaviour. The existing `tests/examples_engines.rs` cross-engine + parity suite covers runtime correctness. + +## Capture environment + +- Host: macOS 15.5 arm64 +- Rust: stable matching `rust-toolchain`

Phase 5 Stage 5b regression test: post-refactor Cranelift AOT codegen is +//! byte-for-byte identical to the pre-refactor baseline at the Cranelift +//! object-file level. +//! +//! ## Why the object file, not the linked binary +//! +//! The linked binary contains all of `libilo.a`. Every Rust code addition to +//! the `ilo` crate (the trait scaffolding, the HIR module, anything new) +//! changes `libilo.a` and therefore the linked binary, even when Cranelift +//! codegen is unchanged. Asserting byte-identity on the linked binary would +//! fail spuriously on every code addition to the crate. +//! +//! The Cranelift-emitted `.o` file isolates the AOT codegen output. It +//! contains exactly the bytes Cranelift produced from the ilo source, plus +//! a `main()` shim, plus a Mach-O / ELF header. It is deterministic across +//! runs and across output paths (verified empirically — see manifest). +//! +//! ## How baselines are captured +//! +//! The build sets `ILO_KEEP_OBJ=1` to preserve the `.o` file that +//! `compile_to_binary` would otherwise delete after the link step. The +//! baseline-capture pass walks every `-- run:` annotated example, records +//! the sha256 of each `.o`, and writes them to +//! `tests/aot-baselines/obj-baselines.tsv`. Stage 5b reproduces those +//! sha256s; future stages re-capture when the codegen itself intentionally +//! changes. +//! +//! ## Running locally +//! +//! `cargo test --release --features cranelift --test aot_byte_identical`. +//! The test parallelises poorly because each entry spawns a full +//! `ilo build`, but the corpus is small (~136 examples) and the wall time +//! is acceptable as a release-gate. + +// Byte-identity baselines were captured on macOS 15.5 arm64 (Mach-O AArch64 +// object files).

Phase 5 Stage 5c regression test: post-refactor Python transpile output is +//! byte-for-byte identical to the pre-refactor `--emit python` output. +//! +//! ## How the baselines were captured +//! +//! Before moving `src/codegen/python.rs` to `src/backend/python/`, the +//! pre-refactor `ilo --emit python` stdout was captured for a +//! curated set of examples and committed to `tests/python-baselines/`.
