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absorbed/superseded.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.

// E6BR-4 (MIXED pack source — the trap cell) — a pack-closure param-impl source
|
|
// `Closure(*Box, ..$args) -> $R` mixes a CONCRETE fixed prefix (`*Box`) with pack
|
|
// metadata (`..$args`, `$R`). The reconciled choke-point decides template-vs-author
|
|
// AT THE LEAF: `*Box` is resolved SOURCE-AWARE through `resolveCompound` while
|
|
// `..$args`/`$R` stay pack metadata via `PackResolver` — NOT a top-level
|
|
// "contains-unbound → no-author wrapper" router, which would send `*Box` down the
|
|
// global last-wins path (the trap both engines flagged). With two flat `Box`
|
|
// authors and none own, the concrete `*Box` prefix is a genuine collision and the
|
|
// build exits 1 — proving the prefix IS routed source-aware (it caught the
|
|
// ambiguity) while the pack parts did not spuriously error.
|
|
//
|
|
// Fail-before (pre-E6BR-4): the wrapped/pack source fell to the no-author
|
|
// `type_bridge.resolveTemplateSignatureType` wrapper (global last-wins, no
|
|
// diagnostic), so the `*Box` collision registered silently. Protects the pure-pack
|
|
// `Closure(..$args) -> $R` bridge in `library/modules/std/objc_block.sx` (0504 /
|
|
// 1302 / 1304 stay byte-identical), whose single author keeps the prefix-free path.
