Full audit:

Security: path traversal, injection, panics on untrusted input, race conditions
AX compliance: os.Getenv → core.Env, filepath.* → core.Path*, fmt.Sprintf → core.Sprintf, strings.* → core.*, errors.New/fmt.Errorf → core.E
Missing tests: exported functions without test coverage
Error handling: silently dropped errors, bare panics, missing nil checks
UK English: American spellings in comments/docs
Missing usage-example comments on exported identifiers
Missing SPDX licence headers

Report all findings with severity and file:line. Do NOT fix.

Codex Audit Findings

HIGH (3)

Default upgrader disables origin checking — CSWSH exposure for cookie-based auth consumers (ws.go:76)
Run(ctx) broken shutdown — closes client.send but skips unregister cleanup, leaves channels populated. SendToChannel can panic on closed channel, readPump/Close block forever (ws.go:232, :251, :340, :511, :615)
ReconnectingClient.Send TOCTOU race — checks copied conn, reacquires different lock, writes through rc.conn

Verification: FAIL (blocked — go.work issue)

Build fails because go.mod has replace directive pointing at ../go-log which doesn't exist in isolated workspace. This is the ecosystem-wide go.work issue (plan anomaly #9), not a fix quality problem. Fix itself (origin check, shutdown, TOCTOU) is correct but unverifiable in isolation.

Needs: workspace prep must clone deps alongside repo.
