Phase 25.1b: Complete SSA fix - eliminate all global ValueId usage in function contexts.
Root cause: ~75 locations throughout MIR builder were using global value
generator (self.value_gen.next()) instead of function-local allocator
(f.next_value_id()), causing SSA verification failures and runtime
"use of undefined value" errors.
Solution:
- Added next_value_id() helper that automatically chooses correct allocator
- Fixed 19 files with ~75 occurrences of ValueId allocation
- All function-context allocations now use function-local IDs
Files modified:
- src/mir/builder/utils.rs: Added next_value_id() helper, fixed 8 locations
- src/mir/builder/builder_calls.rs: 17 fixes
- src/mir/builder/ops.rs: 8 fixes
- src/mir/builder/stmts.rs: 7 fixes
- src/mir/builder/emission/constant.rs: 6 fixes
- src/mir/builder/rewrite/*.rs: 10 fixes
- + 13 other files
Verification:
- cargo build --release: SUCCESS
- Simple tests with NYASH_VM_VERIFY_MIR=1: Zero undefined errors
- Multi-parameter static methods: All working
Known remaining: ValueId(22) in Stage-B (separate issue to investigate)

Implemented:
- UsingResolverBox full implementation in using_resolver_box.hako
- state_new(): Empty state creation
- load_modules_json(): Load modules JSON from nyash.toml
- resolve_path_alias(): Resolve paths from aliases
- resolve_namespace_alias(): Tail segment matching with case-insensitive support
- to_context_json(): Generate context JSON for ParserBox
- Added sh_core entry to nyash.toml modules section
- Maps to lang/src/shared/common/string_helpers.hako
- Fixes "using not found: 'sh_core'" errors
- Cleaned up compiler_stageb.hako
- Removed problematic using statements
- Added documentation
Known Issue (to be fixed next):
- Body extraction bug in compiler_stageb.hako:51-197
- Multiline source extraction fails for "static box Main { main() {...} }"
- Results in empty Program JSON body
- Causes Stage-B emit pipeline to fall back to jsonfrag (ratio=207900%)
- This is the root cause blocking selfhost builder path
Impact:
- ✅ sh_core resolution errors fixed
- ✅ UsingResolverBox infrastructure complete
- ❌ Stage-B emit pipeline not restored (body extraction bug)
- ❌ Selfhost builder path still blocked
Next Priority: Fix body extraction bug to restore Stage-B pipeline

- restore: lang/src/compiler/** (parser/emit/builder/pipeline_v2) from e917d400
- docs: docs/development/selfhosting/index-operator-hako.md
- smokes(hako): tools/smokes/v2/profiles/quick/core/index_operator_hako.sh (opt-in)
- smokes(vm): adjust index_operator_vm.sh for semicolon gate + stable error text
- rust/parser: allow IndexExpr and assignment LHS=Index; postfix parse LBRACK chain
- rust/builder: lower arr/map index to BoxCall get/set; annotate array/map literals; Fail‑Fast for unsupported types
- CURRENT_TASK: mark Rust side done; add Hako tasks checklist
Note: files disappeared likely due to branch FF to a lineage without lang/src/compiler; no explicit delete commit found. Added anchor checks and suggested CI guard in follow-up.
