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absorbed/superseded.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 — own-wins-over-flat for ERROR-SET per-decl nominal identity. `main`
|
|
// flat-imports `dep.sx` (which authors `IoErr { Net }`) AND authors its OWN
|
|
// `IoErr { Disk }`. A bare `IoErr` reference in `main` resolves to `main`'s OWN
|
|
// author, not the flat-imported one (the querying source's author wins outright —
|
|
// no ambiguity), so `e : IoErr = error.Disk` binds `main`'s set (whose `Disk` tag
|
|
// dep's `IoErr` lacks) while `dep_err()` returns dep's DISTINCT `IoErr`.
|
|
//
|
|
// Fail-before (pre-E6b): the stateless `type_bridge.resolveInlineErrorSet`
|
|
// `findByName` short-circuit interned ONE global last-wins `IoErr`, so `main`'s
|
|
// `IoErr` and dep's `IoErr` collapsed to a single nominal. Whichever author won
|
|
// the global slot, the OTHER module's tag is not in it — so exactly one of
|
|
// `error.Disk` (main) / `error.Net` (dep, in `dep_err`'s body) fails its
|
|
// membership check and the program exits 1.
|
|
//
|
|
// Pass-after: distinct nominal TypeIds — `error.Disk` validates against main's
|
|
// `{ Disk }` and `error.Net` against dep's `{ Net }`, both pass, exit 0.
