Subject: [PATCH] conformance: migrate go onto shared driver (dict, 609/609
 parity)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Go has the same structure as erlang: suites load into one session and each
exposes a pass counter plus a *count* (total) counter rather than a fail
counter. MODE=dict fits — each suite's runner is a dict literal
{:passed P :failed (- count P) :total count}. No driver change; conformance.conf
+ 3-line shim, historical scoreboard schema preserved.

Parity verified 609/609 (0 fail), every suite matching baseline.

 ## Progress log (newest first)
 
+- 2026-06-07 — go: migrated to `MODE=dict`, 609/609 exact parity (lex 129, parse 179,
+  types 102, eval 106, runtime 40, stdlib 41, e2e 12). Same shape as erlang — one-session
+  load, per-suite pass + *count* (total) counters — so each suite's dict-literal runner
+  computes `:failed (- count pass)`. No driver change; conformance.conf + shim only.
+  Kept historical scoreboard schema (language/total_pass/total/suites[name,pass,total,status]).
