kyq (metadatastician/kyq, the estate's KYAML processor) states that "AffineScript 0.1.1 does not parse src/". At 9167b04 the parsing works, but checking and running kyq turned up six faults. Each one is now pinned by a test in test/test_module_root_flatten.ml that fails without its fix; I verified that by reverting each fix in turn.
#
Fault
Fix
1
A file declaring module A.B; in .../A/ resolved imports from .../A/, so use A.C; looked for .../A/A/C.affine. This is a regression from #642: kyq's affine-check passed 11/11 files when the search started at the CWD.
The CLI roots module search above the declared path's directories when they match (Module_loader.module_root_dir). Otherwise it uses the file's own directory, as before (#642).
2
Silent hole. A file found for A.B that declares module A; was accepted as A.B, so use A.Nonexistent::* type-checked and imported A's exports.
New ModuleDeclMismatch load error. No stdlib file's declaration disagrees with its path (checked).
3
A missing transitive dependency (e.g. prelude) was reported as undefined module: <the importer's own import>.
The missing module is named.
4
eval interpreted the unflattened program, so no imported function was bound. Flattening also emitted a selected function before its private helpers, and carried no helpers at all for glob or plain imports.
eval flattens like compile. Every import kind is closed over its helpers, which are emitted in the imported module's declaration order.
5
The interpreter had no ++ on arrays and no ==/!= beyond Int, Float, String and Bool, though the checker accepts them.
Structural Value.value_eq, array append, and Char ordering.
6
H2. Bun-ESM compiled a return in a match arm of a let initializer as a return from the match's IIFE: wrong value, no error.
let initializers and function and lambda tails are lowered to statements (gen_tail_to). A match used as an argument or operand with a return in an arm is refused at compile time rather than miscompiled. expr_contains_return now sees match arms.
Not addressed: H7 (interpreter let mut) and H1 (interpreter early return). Those still stop eval on most real programs, so I ran kyq through Bun-ESM.
docs/COMPLETION-PLAN.adoc: H2 narrowed; H20–H22 recorded as found and fixed, with their test anchor.
Evidence
dune test --force: 573 OK and 33 FAIL. All 33 failures are walker-* tests that need the tree-sitter CLI, which is absent locally. The same 33 fail on a pristine 9167b04 worktree (565 OK there, so the difference is exactly the 8 new tests).
tools/check-capability-anchors.sh: OK.
tools/check-soundness-ledger.sh fails locally on property 4 ("stamp 65c2ae3 not present in history"), identically on pristine HEAD. This is a shallow-clone artefact.
kyq at HEAD, run with this compiler:
all 11 .affine files (8 under src/, plus tests and bench) type-check;
its 19 parser tests and 1 lint test pass under Bun-ESM;
a planted off-by-one in Parser.affine turns 3 of the parser tests red.
Smaller bug noticed, not fixed: affinescript eval --help crashes with a cmdliner "Illegal escape char 'x'". The $(b,\x ->) in the face docstring is the cause.
… kyq)
Checking and running metadatastician/kyq, the estate's KYAML processor,
turned up six faults, each now pinned by a test in
test/test_module_root_flatten.ml that fails without its fix:
- Module root: a file declaring `module A.B;` in .../A/ resolved imports
from .../A/, so `use A.C;` looked for .../A/A/C.affine. The CLI now
roots the search above the declared path's directories when they match
(Module_loader.module_root_dir); otherwise the file's own directory,
as before (#642).
- A file found for `A.B` that declares `module A;` was accepted as
`A.B`, so `use A.Nonexistent::*` type-checked. It is now a
ModuleDeclMismatch load error.
- A missing transitive dependency was reported as the importer's own
import being undefined; the missing module is now named.
- `eval` interpreted the unflattened program, so no imported function
was bound. It now flattens like `compile`. Flattening also emitted a
selected function before the private helpers it calls and carried no
helpers for glob or plain imports; every import kind now carries them,
in the imported module's declaration order.
- The interpreter had no `++` on arrays and no `==`/`!=` beyond Int,
Float, String and Bool, all of which the checker accepts.
- Bun-ESM compiled a `return` in a match arm of a `let` initializer as a
return from the match's IIFE (H2). `let` initializers and function and
lambda tails are now lowered to statements; a match used as an argument
or operand with a `return` in an arm is refused at compile time.
`expr_contains_return` now sees match arms.
H7 (interpreter `let mut`) and H1 (interpreter early return) are not
addressed. docs/COMPLETION-PLAN.adoc: H2 narrowed, H20-H22 recorded.
dune test: 573 OK; the 33 walker-* failures need the tree-sitter CLI and
fail identically on 9167b04. With this change all 11 kyq source, test and
bench files type-check, and kyq's 20 tests pass under Bun-ESM.

The interpreter now supports array concatenation, equality comparisons across value types, and ordering comparisons between characters.
Bug Fixes
Module imports now resolve dependencies more reliably, including private helpers needed by imported declarations. Files whose declared module paths do not match their requested paths are reported as errors.
In Bun-ESM builds, return in match arms now exits the enclosing function or lambda in supported positions. Compilation rejects cases where it cannot safely preserve that behavior.
Module loading now uses declared module paths and validates module declarations. Evaluation flattens imports before interpretation. The interpreter supports additional binary operators. Bun-ESM code generation handles returns in supported match and expression positions and rejects unsupported sub-expression cases.
Loader configuration uses the parsed program’s declared module path. The loader reports declaration mismatches, and import resolution distinguishes a missing requested module from a missing transitive dependency.
Import closure and evaluation lib/module_loader.ml, bin/main.ml, test/test_module_root_flatten.ml, docs/COMPLETION-PLAN.adoc
Import flattening includes referenced helpers and enum types, and emits declarations in source order. Both evaluation paths flatten imports before interpretation.

Summary
Return lowering and validation lib/ast.ml, lib/codegen_deno.ml, test/test_module_root_flatten.ml, test/test_main.ml, docs/COMPLETION-PLAN.adoc
Code generation preserves returns in supported tail and initialiser positions. It rejects match expressions with returns when used as sub-expressions. Tests cover emitted JavaScript behaviour and the rejection case.
hyperpolymath/affinescript#786: Documents the Bun-ESM match-arm return issue and the interpreter early-return issue. This PR changes Bun-ESM return lowering but does not address the general interpreter early-return issue.

Review comments at @bin/main.ml:
- Around line 191-194: Update the language-server configuration around
Affinescript.Module_loader.module_root_dir to derive the loader root from the
document path and parsed module declaration, matching the CLI’s resolution
behaviour; preserve the document’s navigation cache when module resolution
fails.
- Around line 191-194: Normalise the source directory before matching module
paths so paths containing components such as `.` resolve to the same module root
as their canonical form. Update the `current_dir` calculation using
`Filename.dirname absolute_path` and
`Affinescript.Module_loader.module_root_dir`, preserving filesystem path
semantics and the existing `mod_path`.
- Around line 191-194: Update the module search-path setup in the config
construction around `Affinescript.Module_loader.module_root_dir` to search both
the package root and the source directory, preserving imports such as `A.Main`
finding sibling `A/Helper.affine`. Add a regression test covering this
nested-module import.
- Around line 327-328: Update both evaluation paths around
Affinescript.Interp.eval_program to check for main in the original root prog
declarations before automatically invoking it; do not let main added by
Affinescript.Module_loader.flatten_imports trigger an automatic call. Preserve
imported functions for normal program resolution.
Review comments at @lib/codegen_deno.ml:
- Around line 1677-1681: The match-arm return check using expr_contains_return
only catches returns in directly traversed expressions, allowing returns nested
in aggregates to be consumed by the block IIFE. Extend the check for arm.ma_body
to detect returns recursively inside aggregate expressions, retain the existing
arm.ma_guard check, and fail before generating the unsupported match expression.
- Around line 1960-1963: Update the `let js` lowering decision to handle
wildcard initialisers containing early returns: lower them to statements while
discarding their normal values. Preserve the existing IIFE behaviour for `if`
and block initialisers where it allows the function to continue.
- Around line 1968-1972: Update temporary-name allocation around
`let_tmp_counter` and the generated `__scrut_N` names so both `__let_tmp_N` and
scrutinee temporaries are checked against source identifiers and previously
allocated temporaries. Choose an unused name before emitting each declaration,
preserving the existing lowering behaviour while preventing collisions and
shadowing.
- Around line 1909-1914: Update the arm generation in arms_js so pattern
bindings from gen_pattern_bindings are introduced before evaluating ma_guard. If
the pattern matches but the guard is false, continue to arms_js for the
remaining arms; preserve the existing pattern-mismatch fall-through.
- Around line 1901-1903: Update the `if` and `ExprMatch` generation paths in
`gen_tail_to` so return-bearing conditions and scrutinees are emitted as
statements before branch or arm selection, rather than wrapped in an IIFE by
`gen_expr`; preserve the existing branch and arm behaviour for inputs without
returns.
- Around line 1911-1914: Update the guard handling in `arms_js` so returns in
match guards propagate from the enclosing function instead of being evaluated as
truthy IIFE results. Lower return-bearing guards as statements; if that cannot
be supported safely, reject them explicitly rather than emitting incorrect match
behavior.
Review comments at @lib/interp.ml:
- Around line 559-562: Character ordering currently fails during type checking
before the interpreter’s relational operator arms can handle it. Update the type
checker’s comparison rules to allow ordering comparisons on characters, and add
a source-level regression test confirming a character ordering expression
type-checks and evaluates correctly.
Review comments at @lib/module_loader.ml:
- Around line 238-240: Update the module candidate search around the
ModuleDeclMismatch branch to continue checking remaining configured directories
after a parent-file mismatch; report the mismatch only if no valid candidate is
found, preserving the existing mismatch error in that case.
- Around line 238-240: Update the module-loading failure handling around
loader.loading and ModuleDeclMismatch so every failed load removes the current
module’s loading marker, including when a dependency fails. Preserve the
original error result and ensure retrying the parent module with the same loader
does not report a false cycle.
- Around line 465-467: Update find_free_vars to collect dependencies from record
shorthand fields and record spreads, resolving shorthand names as free-variable
references and traversing spread expressions. Preserve the existing dependency
traversal for other expression forms.
- Around line 550-552: Update the `close_over` result handling in the `List.map`
that calls `bound_name_of` and `rename_decl` so an imported alias also preserves
the original module-local binding required by declarations such as `api`. Ensure
references within imported declarations continue to resolve to `helper` while
the aliased name `renamed` remains available to the importing module.
- Line 506: Update the binding construction around List.stable_sort so
interpreter closures capture the complete function environment, including later
helpers and their own recursive bindings, rather than only names available in
source order. Preserve the existing ordering behaviour where it is needed, but
ensure it does not exclude functions from closure environments.
- Line 509: Update the ImportGlob handling in close_over so private helpers from
each imported module retain module-specific bindings, and update references
within that module to use those bindings. Ensure helpers with identical names
remain distinct after flattening, while preserving the existing public
declarations.
Review comments at @test/test_module_root_flatten.ml:
- Around line 248-251: Add an Alcotest case alongside the existing list and glob
cases in the test registration block, reusing flatten_carries_helpers with a
plain import to cover ImportSimple.

Use the document’s package root in the language server.
When the server starts outside the package root, it can report Kyaml.Types as missing even though CLI checking finds it. Resolution failure also clears the document’s navigation cache. Derive the loader root from the document path and parsed module declaration, as the CLI does.

Make later and recursive functions available to interpreter closures.
If an imported function calls a later helper or itself, source ordering leaves that name outside its captured environment. Evaluation then fails with an unbound-variable error, even though the module checks successfully. Make the interpreter’s function bindings available to these closures.

Review comment at @lib/module_loader.ml at line 506:
Update the binding construction around List.stable_sort so interpreter closures
capture the complete function environment, including later helpers and their own
recursive bindings, rather than only names available in source order. Preserve
the existing ordering behaviour where it is needed, but ensure it does not
exclude functions from closure environments.

Keep private helpers distinct across modules.
When two glob-imported modules use private helpers with the same name, flattening retains only the later helper. Both wrappers can then call that helper and return the wrong value. Give each imported helper a module-specific binding and update its references.

Update the ImportGlob handling in close_over so private helpers from each
imported module retain module-specific bindings, and update references within
that module to use those bindings. Ensure helpers with identical names remain
distinct after flattening, while preserving the existing public declarations.

Preserve module-local references when applying import aliases.
When use M::{helper as renamed, api} imports a helper that api calls, flattening renames the helper but leaves api referencing helper. Calling api during evaluation can then fail with Unbound variable: helper. Preserve the helper’s module-local binding when applying the alias.

Review comment at @lib/module_loader.ml around lines 550 - 552:
Update the `close_over` result handling in the `List.map` that calls
`bound_name_of` and `rename_decl` so an imported alias also preserves the
original module-local binding required by declarations such as `api`. Ensure
references within imported declarations continue to resolve to `helper` while
the aliased name `renamed` remains available to the importing module.

Add a simple-import helper regression test.
The helper tests cover list and glob imports, but not ImportSimple. If that branch stops carrying private helpers, these tests will not detect it. Register the existing fixture for a plain import.

kyq (metadatastician/kyq, the estate's KYAML processor) states that "AffineScript 0.1.1 does not parse src/". At
