Resolver-target corpus — enumerated manifest

Status: INACTIVE / xfail from S0 through S3.8. Flips to active + green at S3.9. Not part of the baseline gate (run_examples.sh does not run these — no active examples/expected/ marker). The harness runner run_resolver_target.sh asserts every case below currently FAILS to match its TARGET, so the set is never silently dropped between S0 and S3.9.

These cases encode known-wrong old behavior on wt-stdlib-base (E6b unmerged): the old name-selector silently resolves a global last-wins author (exit 0) where the TARGET is a loud ambiguity (exit 1), OR fails to resolve an own-author where the TARGET is success (exit 0), OR resolves the wrong author (right exit, wrong bytes). On this base the old selector is not a valid oracle for them — so they are NOT baseline-green and the S2 mirror must NEVER assert resolver == old-selector over this corpus (see ../../docs/fork-c/S0.2-e6b-disposition-and-two-corpus-partition.md).

The 08xx TARGET goldens here are the exact bytes the E6b branch (flow/stdlib/E6b @ af737b0) produced; copied verbatim, never the transitional src. e6br5-… has a spec target only (*.target.md) — its exact bytes are produced by the Fork C resolver at S3.9.

Failure classes

• SILENT-RESOLVE (ambiguous): base exits 0 (silently picks last-wins) where TARGET is exit 1 (loud ambiguity). The resolver must error.
• UNDER-DIAGNOSE (ambiguous): base exits 1 but emits FEWER ambiguity diagnostics than the TARGET (catches one site, silently resolves the rest).
• WRONG-AUTHOR (own-wins): base exits 0 but resolves the wrong author → garbage runtime bytes vs the TARGET stdout.
• OWN-WINS-FAILS (own-wins): base exits 1 (fails to resolve the own-author) where TARGET is exit 0 (own-author wins and the program runs).

Provenance

• Cases 1–17: source trees harvested from flow/stdlib/E6b @ af737b0 into examples/<name>.sx (+ sibling module dir), goldens copied verbatim from flow/stdlib/E6b:examples/expected/<name>.* into expected/<name>.* here. The transitional E6b src was NOT harvested.
• Case 18 (E6BR-5): authored reproducer (no E6b tree ever existed); lives entirely under cases/ with a spec target in expected/…target.md.

Flip at S3.9

Each row maps to an active examples/expected/<name>.{exit,stdout,stderr} marker when it flips (the 08xx trees are already in examples/; only the goldens move from expected/ here to examples/expected/). After S3.9 this harness is empty and every entry above is an active, green baseline test validated against its TARGET.
