 ## Progress log (newest first)
 
+- 2026-06-07 — common-lisp: UNBLOCKED + migrated. Extended the shared driver's
+  `MODE=counters` (lib/guest/conformance.sh) with a backward-compatible SUITES format
+  `name:file[:pass-var:fail-var[:extra-preload ...]]` — optional per-suite counter
+  symbols and per-suite preload chains. Authored lib/common-lisp/conformance.conf (12
+  suites, 8 distinct counter pairs, per-suite preloads, base PRELOADS=stdlib+prefix;
+  kept historical scoreboard schema) and replaced conformance.sh with the shim.
+  Result 487/487 (0 fail) — HIGHER than the 305/0 baseline, explained: the old script's
+  per-suite `timeout 30` was too tight for the slow `eval` suite (~15–25s under
+  contention), silently recording it as 0; the driver's 180s budget recovers its true
+  182. geometry/mop-trace remain 0/0 (pre-existing `refl-class-chain-depth-with` load
+  error; counter vars defined as 0 → clean gc-result, no fail-fallback). Regression:

 ## Blocked
 
-- **common-lisp** — the shared driver's two modes can't reproduce its 305/0 breakdown:
-  1. **Per-suite counter variable names.** Old script reads 8 distinct pairs across
-     its 12 suites: `cl-test-pass`/`cl-test-fail` (read, lambda, eval), `passed`/`failed`
-     (conditions, clos), `demo-passed`/`demo-failed`, `parse-passed`/`parse-failed`,
-     `debugger-passed`/`debugger-failed`, `geo-passed`/`geo-failed`,
-     `mop-passed`/`mop-failed`, `macro-passed`/`macro-failed`, `stdlib-passed`/`stdlib-failed`.
-     `MODE=counters` supports only one global `COUNTERS_PASS`/`COUNTERS_FAIL`.
-  2. **Per-suite preload chains.** Each suite loads a different file set
-     (e.g. read: `reader.sx`; clos: `runtime.sx clos.sx`; macros: `reader parser eval loop`).
-     `MODE=counters` loads one fixed `PRELOADS` set before every suite.
-  `MODE=dict` also fails: these tests run at *load* time mutating globals (no
-  `-tests-run!` runner fns), and dict mode loads all suites into one session — the
-  shared `passed`/`failed` counters used by both conditions and clos would collide.
-  **Unblock path (driver enhancement, deferred — out of this loop's per-iteration scope):**
-  extend `MODE=counters` with optional per-suite counter names and per-suite preloads
-  in the `SUITES` entry format (backward-compatible with the `name:file` shape haskell
-  uses). Same gap likely affects other remaining candidates; worth a one-time driver
-  change before resuming migrations.

+- **common-lisp** (resolved 2026-06-07) — needed per-suite counter names + per-suite
+  preload chains, unsupported by the original `MODE=counters` (single global counter +
+  fixed PRELOADS). Resolved by extending the shared driver: `MODE=counters` now accepts
+  `name:file[:pass-var:fail-var[:extra-preload ...]]` (backward-compatible). **This same
+  extension is available to later candidates** — erlang/forth/etc. with per-suite
+  counter names or preload chains can now migrate via the extended format instead of
+  blocking.
