S0 of the ratified Fork C plan (zero-legacy name-resolution redesign, S0→S6).
Pure setup/documentation: NO production code change, NO behavior change.
Single-author output byte-identical to wt-stdlib-base by construction.
Deliverables under docs/fork-c/ (docs/, not current/, because current/ is
gitignored and the contract must be committed):
S0.1 — byte-baseline + commit-discipline: the committed examples/expected/*
snapshots are the single-author byte-identity reference; the zero-diff repro is
`zig build && zig build test && bash tests/run_examples.sh`. Resolver-target set
explicitly excluded + listed. Commit-classification rule: mirror | consumer-cutover | deletion.
S0.2 — E6b disposition + two-corpus partition: transitional E6b src NOT merged
(grep-clean: no resolveRegistrationSigTypeInSource / sig_registration_mode /
e6br_gate.test.zig on baseline). Harvested 0811–0829 trees + goldens (never the
src), empirically partitioned by running each through the base compiler vs the
E6b target:
- baseline-green (mirror-equivalence): 0795–0798 (merged) + 0823, 0828 — given
examples/expected/ markers, locked into the S0 baseline.
- resolver-target (known-wrong old behavior): 0811–0822, 0824–0827, 0829 + the
re-filed E6BR-5 nested-pattern regression — a listed xfail harness under
tests/resolver-target/ (manifest + TARGET goldens, NO active marker), flips
active+green at S3.9. 0811/0829 noted as old-selector-wrong on the E6b-unmerged
base; E6BR-5 subsumed by the whole-AST resolver, NOT an E6b attempt-6.
S0.3 — A–E6 reuse/delete ledger: every load-bearing A–E6 artifact mapped REUSED
(Fork C home) or DELETED/TRANSITIONAL (S3/S6 phase); E6c/d/e dropped, F/H/I/K
absorbed/superseded.
Gate over the baseline-green corpus: zig build + zig build test (LSP corpus sweep
574 files, no crash) + bash tests/run_examples.sh (540 passed, 0 failed) all exit 0.

// E6b — per-decl nominal identity for ERROR-SET decls. A bare ERROR-SET reference
|
|
// is non-transitive AND ambiguity-checked at every site, exactly like the struct
|
|
// leaf (0755) and the enum/union leaves (0795/0797). `main` flat-imports two
|
|
// modules that each author a same-name `IoErr` error set and authors none itself,
|
|
// so EACH of the following bare ERROR-SET forms is a genuine collision the source
|
|
// cannot disambiguate — and each must emit the LOUD "type 'IoErr' is ambiguous"
|
|
// diagnostic and poison the result, NEVER silently pick a global `findByName`
|
|
// last-wins author:
|
|
//
|
|
// - reflection / type-arg slot `size_of(IoErr)`
|
|
// - typed error-value annotation `e : IoErr = error.Disk`
|
|
// - type-as-value `t : Type = IoErr`
|
|
// - type-category match arm `case IoErr:`
|
|
// - `!Named` failable channel `-> !IoErr` (E6b audited use surface)
|
|
//
|
|
// Fail-before (pre-E6b): the stateless `type_bridge.resolveInlineErrorSet`
|
|
// `findByName` short-circuit interned ONE global last-wins `IoErr`, so every bare
|
|
// form silently resolved to it; the `!IoErr` channel resolved through
|
|
// `resolveErrorType -> resolveTypeName` straight to that global slot. The program
|
|
// exited 0.
