Summary by CodeRabbit
WalkthroughThe compiler now supports pure helper calls, conditional expressions, statement branches, and bounded list loops. Core IR, canonical encoding, lawpack projection, validation, CLI serialization, tests, and documentation cover these constructs. Wasmtime is updated to 46.0.2. ChangesCompiler spine

Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to This PR adds lawpack-bound helper and type resolution plus bounded control-flow lowering, but unresolved loop bounds can understate helper cost, local names can resolve as imported helpers, and recursive type references can accept foreign facts. These issues can produce incorrectly validated Core, so merge should wait for fixes or explicit owner acceptance. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@crates/edict-syntax/src/compiler.rs`:
- Around line 1119-1139: Update check_for_stmt and its BodyState recursion to
enforce cumulative loop-step accounting across sequential and nested loops,
multiplying nested bounds by the enclosing step factor and rejecting checked
arithmetic overflow or totals above intent.budget.max_steps with InvalidBound.
Add a RED test covering nested bounded loops before implementing the fix, and
preserve the existing bound validation behavior.
- Around line 672-681: Align the non-literal coordinate-bound handling in
type_ref_shape with string_shape and bytes_shape by using one consistent
CompilerErrorKind for this unsupported compiler subset. Since the sibling
functions use UnsupportedSourceShape, update the list maximum branch to emit
that same kind while preserving its existing diagnostic and early return.
- Around line 2388-2390: Update conditional branch checking around
check_expr_with_expected so bare integer literals can inherit the expected width
from either branch, reusing is_bare_integer_literal as in
check_compare_predicate. Preserve explicit expectations and ensure both
then/else ordering cases are accepted; add the mirrored compiler_spine fixture
and CSPINE-TP-024 test-plan entry.
In `@crates/edict-syntax/tests/compiler_spine.rs`:
- Around line 451-477: Add a coordinate-bound regression test alongside
digest_bound_coordinate_loop_cap_lowers_to_core and
missing_coordinate_loop_cap_rejects_before_core that supplies BoundFact values 3
and 9 for bounds.maxItems, verifies compile_to_core returns InvalidBound for
both unsound and over-budget cases, and records this verification against
CSPINE-TP-028 in test-plan.md.
In `@crates/edict-syntax/tests/lawpack.rs`:
- Around line 790-834: Extend
exact_lawpack_constant_enters_loop_bound_compilation with a U32 acceptance case
and a U64 case exceeding the list maximum; assert the latter returns
CompilerErrorKind::InvalidBound rather than merely checking failure. Update
docs/topics/lawpacks/test-plan.md lines 82-83 to list the new test names in the
Evidence column, retaining the U32 and static-proof claims only when backed by
those tests.

- Around line 2957-2966: Update the recursive lookup in
imported_type_definition_shape to require
coordinate_is_below_lawpack(fact.coordinate, lawpack) in addition to the
existing lawpack match, rejecting foreign coordinates before recursive
resolution; add a regression test covering a malformed nested TypeShapeFact that
would otherwise be lowered into a List item.
In `@crates/edict-syntax/tests/external_action_requests.rs`:
- Around line 414-437: Add a companion boundary test near the existing
nesting-limit case in the core module encoding test, constructing exactly
MAX_CANONICAL_NESTING_DEPTH loop layers rather than using an inclusive range.
Clear core.imports before encoding, then assert the result reaches
request-closure validation with CanonicalErrorKind::UnsupportedValue; retain the
existing excessive-depth assertion for the rejecting case.
In `@crates/edict-syntax/tests/lawpack.rs`:
- Around line 844-883: The test
nested_exported_type_closure_enters_pure_helper_compilation needs a negative arm
that preserves the nested GreetingKey definition while omitting the
hello.echo@1.GreetingAtom export, then asserts the compilation fails with
CompilerErrorKind::UnresolvedType rather than only asserting success. In
docs/topics/lawpacks/test-plan.md:82, remove the nested exported-type portion
from implemented or list it under Open Gaps until that negative test provides
executable evidence.

Do not create draft pull requests, and never use acodexprefix in branch names, pull request titles, or commit messages.
Pull requests for issue work must include GitHub auto-close text such asCloses#123`` for every issue they intend to close.
Usecodex-think --remember --jsonwhen starting a session, entering the repository, or regaining context, and record significant durable events with `codex-think "..." --json`. Treat Think as memory rather than repository truth.

Use Mermaid diagrams for nontrivial flow, lifecycle, ownership, or component interaction when clearer than prose; every diagram requires an introductory paragraph, the diagram, the exact collapsed caption structure, and a concluding interpretation.
Tag each material technical claim at first occurrence as `[claim:, confidence:]`, cite evidence using repository-relative paths, line numbers, and Git SHAs, and end the explanatory body with a collapsed citations appendix.
If CodeRabbit is actively reviewing, obtain its approval before merge; if unavailable due to limits or credits, request `@codex review please` and wait for the alternate response. Do not treat unavailability as approval unless a maintainer explicitly overrides the gate.

In `@crates/edict-syntax/src/compiler.rs`:
- Around line 1064-1076: Update helper_cost_for_stmt’s Stmt::For handling to
propagate failure from helper_cost_loop_bound instead of defaulting an
unresolved bound to zero, preserving fail-closed helper-cost accounting. Add a
deterministic regression test for a costed helper inside a loop with an
unresolved coordinate bound, asserting the cost-stage error kind, and record the
case in the owning test plan.
- Around line 1681-1687: Update resolve_loop_bound to replace the nested
let-else and unreachable! with one exhaustive match over BoundRef, preserving
the existing coordinate handling and returning the same literal CoreBound tuple
for the Int variant.
In `@crates/edict-syntax/tests/compiler_spine.rs`:
- Around line 1072-1091: Add a bound-path test alongside
coordinate_bound_source_qualifier_must_match_the_owning_import that preserves
the imported bounds alias but changes only the coordinate-bound export suffix,
asserting compilation fails with MissingContextFact. This must isolate
canonical-suffix validation from missing-alias validation; update the
CSPINE-TP-030 oracle in the test plan to record the new bound-path witness.
- Around line 690-710: Extend the branch-order witness in
crates/edict-syntax/tests/compiler_spine.rs:690-710 by increasing
max_allocated_bytes to 600 and max_output_bytes to 200, so both budget
dimensions distinguish component-wise maximum from summation alongside
max_steps. After this test change, retain the component-wise maximum statement
in docs/topics/compiler-spine/README.md:100-102. Update
docs/topics/compiler-spine/test-plan.md:61 to mark CSPINE-REQ-031 as verifying
all three dimensions; if the witness is not extended, narrow the README claim
and record allocation/output as open gaps instead.
- Around line 767-777: In the compiler spine tests around EXPORTED_LIST_LOOP,
add a control case that compiles the unchanged source with loop_helper_context()
and asserts success. Keep the existing witness test that adds helpers.bump and
expects InvalidBound, making clear the control removes only helpers.bump while
retaining the outside-loop helpers.identityList call.
In `@crates/edict-syntax/tests/lawpack.rs`:
- Around line 899-912: Extract the duplicated typed-helper intent source
construction into a helper such as typed_helper_list_source that accepts the
manifest digest and returns the formatted source. Replace both source literals
with calls to this helper, preserving identical content except for the digest so
the missing-nested-export test remains isolated.
- Around line 884-887: Harden the mutation in the lawpack test by verifying that
the element removed from the types collection is specifically GreetingAtom,

- Line 82: Update the LAWPACKS-TP-012 Evidence column to include
pure_helper_costs_are_charged_at_call_sites_and_inside_loops from
compiler_spine.rs, alongside the existing ownership test, so the documented
compiler cost-charging claim has executable evidence.
In `@docs/topics/result-projections/test-plan.md`:
- Line 22: Extend
structured_core_effects_cannot_disappear_from_projection_validation in
result_projection.rs with a CoreNode::For whose CoreBlock body contains the
existing branch/effect scenario, importing CoreBound as needed. Ensure the test
exercises recursion through both loop and branch constructs; otherwise narrow
RESULT-PROJ-REQ-008 and record loop handling as an open gap.

- Around line 121-122: Update the compiler-spine test plan to add an executable
witness for let-else inside a bounded loop, confirming CoreNode::Effect is
emitted within CoreNode::For; record that result-projection validation rejects
the enclosing loop with CoreTargetMismatch and Target IR lowering rejects the

Use Mermaid diagrams for nontrivial flow, lifecycle, ownership, or component interaction when clearer than prose; every diagram requires an introductory paragraph, the diagram, the exact collapsed caption structure, and a concluding interpretation.
Tag each material technical claim at first occurrence as `[claim:, confidence:]`, cite evidence using repository-relative paths, line numbers, and Git SHAs, and end the explanatory body with a collapsed citations appendix.
If CodeRabbit is actively reviewing, obtain its approval before merge; if unavailable due to limits or credits, request `@codex review please` and wait for the alternate response. Do not treat unavailability as approval unless a maintainer explicitly overrides the gate.
For release preparation, write the release thesis first, reconcile changes from the previous tag, update release policy and tests, verify the milestone has no open issues and no unauthorized crates.io publication occurred, and record a durable release report.

When an Edict helper matches a variant, this loop never reads the arm's case and admits any declared binder directly into scope without checking it against the case payload. A helper can therefore use a nonexistent or duplicate case, omit cases entirely, or bind a payload as an unrelated type while still being projected as a total, signature-correct helper. Fresh evidence after the earlier variant-constructor validation is that match expressions still discard the inferred scrutinee type and never compare their arms with its case map; require exhaustive unique cases and case-specific binder presence/types.

When an inline helper contains a call predicate, this arm validates only its argument expressions and never even reads the required predicate coordinate. Consequently, a nonexistent predicate, wrong arity/types, or a recursive predicate call is accepted without entering the exported-helper call graph, allowing a digest-bound helper that cannot execute totally to become a compiler fact. Fresh evidence after the earlier callee validation is that this predicate-specific path bypasses both signature lookup and the scanner that recognizes only callee fields; validate it against an owned signature or reject this predicate form until supported.

There was a problem hiding this comment.
When a helper's declared result is any type—including U64 or a bounded collection—a Core capability constant is inferred as that expected type verbatim, so the subsequent exact-type check necessarily succeeds. The lawpack can therefore advertise an ordinary typed result while its implementation returns a capability receipt value, and application compilation trusts the false signature. Fresh evidence after the earlier scalar fixes is this remaining arm's unconditional propagation of expected; resolve and require the CapabilityRef<...> family instead.

When one Edict helper calls an exported generic helper, each supplied type argument is accepted as any nonempty string rather than being resolved against built-ins, the exported type closure, or the caller's type parameters. A nongeneric outer helper can therefore call a generic component or Edict helper with an unused type parameter instantiated as NotAType; its concrete arguments and result still pass validation, the outer helper becomes callable, and execution is left with an invalid instantiation despite the totality claim. Fresh evidence after the earlier generic application-call fix is that this internal inline-call path checks only argument count and text shape.

Summary
Architecture boundary
This is the compiler-side bounded-program substrate from #192. It adds no Jim, Jedit, rope, or ReplaceRange vocabulary to Echo. Edict-authored source and digest-bound lawpacks own application meaning; runtime execution remains a separate generic-target slice.
Branch-result joins remain in stacked PR #194.
Verification
The complete local gate passed at 6cf652d:
Focused red/green regressions cover dedicated helper-budget closure, exported signature mismatches, forged or unbound locals, mistyped bindings and call arguments, out-of-domain integers, over-bound strings/lists/maps, invalid record and variant selection, cyclic or over-depth helper graphs, over-depth imported aliases, branch-correlated helper/loop costs, and fail-closed helper accounting for unresolved loop bounds. Calibrated controls retain both 128-level depth boundaries and reject the 129th level; the loop-cost control retains the outside-loop helper while removing only the budget-breaking inside-loop helper. The broader gate covers formatting, warnings-denied Clippy, all workspace tests and doctests, canonical and golden checks, contract checks, CLI goldens, provider fixtures, and diff hygiene.
