…c/parse_conform.t27 Ports the W577 parser conformance table (all 25 rows), evaluate's verdict decision (evaluate_from), the per-row check of run (case_ok), run as a failure count over injected results, and total. evaluate keeps an undefined body: it calls the host's parsers.

Ports
bootstrap/src/parse_conform.rs(W577 parser conformance table) tospecs/port/bootstrap/src/parse_conform.t27. One file,.t27only.What is ported
CASES: all 25 rows (name, input, verdict, expected decls, expected discards), extracted mechanically from the Rust table. The prosenoteof each row stays in the original; no logic reads it.evaluate(src): it calls the host's parsers (Compiler::parse_ast,parse_ast_strict,parse_ast_accounted), which a spec cannot call. It keeps its name with anundefined;body that no test calls. Its decision isevaluate_from: given the three parse results, it returns(Verdict, decls, discards).run(): the original formats failures into aVec<Outcome>. t27 has noformat!and no growable list, sorun(actuals)takes the evaluated results, one per row, and returns the number of failing rows. The per-row decision iscase_ok. Decls are compared only for a pinned row with aFullverdict, and discards only when the row pins them, as in the original.total():CASES.len, which is 25.Acceptance criteria
These were run on the Railway t27c lab, with t27c built from origin/master e7afb32 (the Mac binary is stale).
gen-rustandgen-calso succeed.Negative control. I flipped three expected values (total 25->24, run count 2->3, discards 3->0).
test-reportthen printedpass 6, FAIL 3, naming exactly those three tests. The tests are not vacuous.🤖 Generated with Claude Code
