 # Completed Steps
 
-- 2026-08-09: `script/test` now runs
-  `go test -timeout 30s -race -cover ./...` and, on failure, reruns
-  verbosely and then exits non-zero, so a test that fails once and
-  passes on the retry can no longer produce a green build (closes #32).
-  Enabling `-race` showed the suite cannot meet the 20-second policy
-  budget: `internal/cli` exceeds the 30-second timeout because the
-  99MB/100MB boundary cases in `secrets_size_test.go` run roughly 10x
-  slower under race instrumentation. No flags were weakened and no
-  tests skipped; the conflict is tracked in #52 for a decision.
 - 2026-07-07 Adopted scripts-to-rule-them-all: `script/` entrypoints,
   Makefile shims, README Entrypoints section
 - 2026-03-11: Secure Enclave unlocker for hardware-backed secret
