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absorbed/superseded.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.

Resolver-target corpus (Fork C)
The second of the two Fork C resolver-acceptance corpora. See the full contract in
../../docs/fork-c/S0.2-e6b-disposition-and-two-corpus-partition.md.
- What it is: harvested E6b semantics goldens (+ the re-filed E6BR-5 regression)
that encode the TARGET behavior of the Fork C resolver for cases where the
old name-selector is known-wrong on
wt-stdlib-base(E6b unmerged) — it silently resolves a global last-wins author / under-diagnoses / picks the wrong author. On this base the old selector is not a valid oracle, so these are NOT baseline-green. - Why separate: the S2 assert-only mirror proves
resolver == old-selectorover the baseline-green corpus ONLY. Asserting that over these cases would force the new resolver to reproduce the old bug. So they live here, inactive, with NO activeexamples/expected/marker —tests/run_examples.shdoes not run them. - Never silently dropped: every case is enumerated in
manifest.md, its TARGET golden is recorded inexpected/, andrun_resolver_target.shasserts each case currently FAILS to match its target (xfail). If any case unexpectedly MATCHES on the base, the runner flags itLEAKED— it is actually baseline-green and must be re-classified (moved toexamples/expected/), never left here. - Flip at S3.9: the Fork C resolver makes these pass; each golden moves to
examples/expected/<name>.{exit,stdout,stderr}and this harness goes empty.
Layout
manifest.md enumerated list of all 18 cases (class / base-now / target / note)
expected/<name>.exit TARGET exit (08xx: exact E6b bytes; e6br5: spec)
expected/<name>.stdout TARGET stdout (08xx only — exact E6b bytes)
expected/<name>.stderr TARGET stderr (08xx only — exact E6b bytes)
expected/e6br5-*.target.md E6BR-5 spec target (exact bytes finalized at S3.9)
cases/e6br5-*.sx + dir/ E6BR-5 authored reproducer (self-contained)
run_resolver_target.sh xfail runner (NOT part of the baseline gate)
The 08xx source trees live under examples/ (harvested as authored, so their
#import paths resolve exactly as their baseline-green siblings do) but carry no
examples/expected/ marker, so they are inert to run_examples.sh. Only their
goldens live here. The E6BR-5 reproducer lives entirely under cases/ (it is
self-contained — modules/std.sx resolves via the library/ search path).
Run
zig build # build the compiler first
bash tests/resolver-target/run_resolver_target.sh
Expected today (S0): all 18 cases print xfail, 0 leaked, exit 0.
